Description

The present invention relates to a wall structure for installing panels on a wall and a construction method for the wall structure.

Conventionally, one example of a technique for retrofitting panels onto an existing wall is the partition wall described in Patent Document 1. The partition wall described in Patent Document 1 comprises multiple vertical frames, multiple horizontal frames that are hung between two adjacent vertical frames, and a wall panel that is installed on an installation frame formed by the vertical and horizontal frames. The multiple vertical frames are then fixed by being stretched between the ceiling and floor, and the vertical or horizontal frames and the wall panel are connected by the magnetic force of magnets.

Generally, ceilings have low strength and may be damaged if pushed with a strong force. For this reason, there is a problem with the ceiling being damaged if a vertical frame is stretched between the ceiling and floor as in the technology described in Patent Document 1.

In recent years, in apartment buildings and the like, anchors with screw holes are often embedded in the upper part of the wall in advance to prevent holes from being made in the wall by screws such as hooks. In such walls, the screw holes of the anchors can be used to fasten panels to the wall. However, since these anchors are installed in a row on the upper part of the wall, although there are multiple anchors in the horizontal direction, there is only one anchor in the vertical direction. For this reason, even if a panel can be installed on such a wall, there is a problem in that the stability of the panel is insufficient.

Therefore, the objective of the present invention is to provide a wall structure and a construction method for the wall structure that allows panels to be stably installed on the wall without damaging the ceiling.

The wall structure according to the present invention comprises a support that is fixed to a wall in order to mount a panel on the wall, the support having a vertical frame extending vertically, a fastening mechanism that fastens the vertical frame to the wall, and a tensioning mechanism that tensions the vertical frame against the floor.

In this wall structure, the fastening mechanism fastens the vertical frame to the wall, and the tensioning mechanism tensions the vertical frame to the floor, so that the vertical frame can be stably installed on the wall without abutting the vertical frame against the ceiling. Therefore, by attaching a panel to the vertical frame installed on the wall, the panel can be stably installed on the wall without damaging the ceiling. For example, if a screw hole is formed in the wall, the vertical frame can be fastened to the wall using the screw hole. Note that "fastening the vertical frame to the wall" does not only mean that the vertical frame is fastened directly to the wall, but also means that the vertical frame is fastened indirectly to the wall via another member. Similarly, "tensioning the vertical frame to the floor" does not only mean that the vertical frame is tensioned directly to the floor, but also means that the vertical frame is tensioned indirectly to the floor via another member.

In the above wall structure, screw holes may be formed in the wall, and the fastening mechanism may fasten the vertical frame to the screw holes. In this wall structure, the vertical frame is fastened to the screw holes formed in the wall, so that the panel can be stably installed on the wall without damaging the wall.

In the above wall structure, the vertical frame may have a notch for hanging the panel. In this wall structure, the vertical frame has a notch for hanging the panel, so that the panel can be easily installed by hanging the panel in the notch.

In the above wall structure, the wall structure includes a first vertical frame and a second vertical frame arranged horizontally next to each other as vertical frames, and the fastening mechanism may include a horizontal frame extending horizontally and connected to the first vertical frame and the second vertical frame, and a fastening screw for fastening the horizontal frame to the wall. In this wall structure, the first vertical frame and the second vertical frame are connected to the horizontal frame, and the horizontal frame is fastened to the wall by the fastening screw, so that the first vertical frame and the second vertical frame are fastened to the wall via the horizontal frame and the fastening screw. And, because the first vertical frame and the second vertical frame are arranged horizontally next to each other, the stability of the panel can be improved when the panel is attached to the first vertical frame and the second vertical frame.

In the above wall structure, the horizontal frame may have a horizontal long hole that extends horizontally and into which the fastening screw is inserted. In this wall structure, since the horizontal frame has a horizontal long hole that extends horizontally and into which the fastening screw is inserted, the position of the horizontal frame relative to the wall can be adjusted horizontally when the fastening screw is screwed into the wall. Therefore, for example, when a screw hole is formed in the wall, the first vertical frame and the second vertical frame can be fastened to the wall even if the horizontal positional accuracy of the screw hole is poor.

In the above wall structure, the fastening mechanism further includes a connection screw for fastening the first vertical frame and the second vertical frame to the horizontal frame, and one of the vertical frame and the horizontal frame may have a connection screw hole into which the connection screw is screwed, and the other of the vertical frame and the horizontal frame may have a vertical long hole extending vertically into which the connection screw is inserted. In this wall structure, one of the vertical frame and the horizontal frame has a connection screw hole into which the connection screw is screwed, and the other of the vertical frame and the horizontal frame has a vertical long hole extending vertically into which the connection screw is inserted, so that when the connection screw is screwed into the connection screw hole, the position of the first vertical frame and the second vertical frame relative to the horizontal frame can be adjusted vertically. Therefore, for example, after fastening the horizontal frame to the wall, the first vertical frame and the second vertical frame can be braced against the floor by adjusting the fastening position of the vertical long hole relative to the connection screw. Furthermore, for example, if screw holes are formed in a wall, the first vertical frame and the second vertical frame can be fastened to the wall even if the vertical positional accuracy of the screw holes is poor.

The above wall structure may further include a middle horizontal frame arranged to extend horizontally below the horizontal frame and connected to the first vertical frame and the second vertical frame. In this wall structure, the middle horizontal frame arranged to extend horizontally below the horizontal frame is connected to the first vertical frame and the second vertical frame, so that the support can be configured in a frame shape. This increases the rigidity of the support and prevents the positional relationship between the first vertical frame and the second vertical frame from shifting.

In the above wall structure, the middle horizontal frame may have a notch for hanging the panel. In this wall structure, the middle horizontal frame has a notch for hanging the panel, so that the panel can be easily installed by hanging the panel in the notch.

The wall structure described above may further include a panel that is installed on the support, and the panel may have a hook portion that protrudes from the surface facing the support and is hooked to the support. In this wall structure, the panel can be easily installed by hooking the hook portion of the panel to the support.

In the above wall structure, the panel has a protrusion protruding from the surface facing the support below the hooking portion, and the support may have a hooked portion to which the hooking portion is hooked vertically, and an insertion hole into which the protrusion is inserted when the hooking portion is hooked to the hooked portion. In this wall structure, the panel can be installed on the support by hooking the hooking portion of the panel to the hooked portion of the support. Here, if an upward force acts on the panel due to a worker bumping into it, the panel may bounce up and the hooking portion may come off the hooked portion. However, since the protrusion of the panel is inserted into the insertion hole of the support, the upward movement of the panel is restricted even if an upward force acts on the panel due to a worker bumping into it. This prevents the panel from bouncing up, and therefore prevents the hooking portion from coming off the hooked portion.

In the above wall structure, the hooking portion has a first hooking portion that protrudes from the surface on the support side and is hooked to the support in the vertical direction, and a second hooking portion that extends downward from the first hooking portion and is hooked to the support from the opposite side of the panel, and the vertical length of the second hooking portion may be longer than the length of the vertical gap above the protrusion in the insertion hole. In this wall structure, when the hooking portion of the panel is hooked to the hooked portion of the support, the first hooking portion is placed on the hooked portion and the second hooking portion is hooked to the support from the opposite side of the panel. And because the vertical length of the second hooking portion is longer than the length of the vertical gap above the protrusion in the insertion hole, even if an upward force acts on the panel due to a worker bumping into it, the hooking portion can be prevented from coming off the hooked portion.

In the above wall structure, the hooking portion has a first hooking portion that protrudes from the surface on the support side and is hooked to the support in the vertical direction, and a second hooking portion that extends downward from the first hooking portion and is hooked to the support from the opposite side of the panel. If the length obtained by subtracting the vertical length from the hooked portion to the insertion hole from the vertical length from the first hooking portion to the protruding portion is taken as the upper gap length, the vertical length of the second hooking portion may be longer than the upper gap length. In this wall structure, when the hooking portion of the panel is hooked to the hooked portion of the support, the first hooking portion is placed on the hooked portion, and the second hooking portion is hooked to the support from the opposite side of the panel. And, since the panel can only move upward by the upper gap length, the vertical length of the second hooking portion is longer than the upper gap length, even if an upward force acts on the panel due to a worker bumping into it, the hooking portion can be prevented from coming off the hooked portion.

In the above wall structure, the vertical frame may include a ferromagnetic material. In this wall structure, since the vertical frame includes a ferromagnetic material, the panel can be attached to the vertical frame by, for example, a magnet.

The wall structure may further include a panel and a magnet that attaches the panel to the support. In this wall structure, the panel is attached to the support by the magnetic force of the magnet, so that the panel can be easily attached to and detached from the vertical frame.

The wall structure construction method of the present invention fastens a vertical frame that extends perpendicular to the wall and braces the vertical frame against the floor.

In this wall construction method, the vertical frames that extend perpendicular to the wall are fixed and braced against the floor, allowing the vertical frames to be stably installed on the wall without abutting against the ceiling. Therefore, by attaching panels to the vertical frames installed on the wall, the panels can be stably installed on the wall without damaging the ceiling.

In the above wall construction method, the vertical frame may be fastened to screw holes formed in the wall. In this wall construction method, the vertical frame is fastened to screw holes formed in the wall, so the panel can be stably installed on the wall without damaging the wall.

In the above-mentioned wall structure construction method, a first vertical frame and a second vertical frame may be arranged horizontally side by side as the vertical frames, a horizontal frame extending horizontally may be connected to the first vertical frame and the second vertical frame, and the horizontal frame may be fastened to the wall with fastening screws. In this wall structure construction method, a horizontal frame extending horizontally is connected to the first vertical frame and the second vertical frame, and the horizontal frame is fastened to the wall with fastening screws, so that the first vertical frame and the second vertical frame are fastened to the wall via the horizontal frame and the fastening screws. And because the first vertical frame and the second vertical frame are arranged horizontally side by side, the stability of the panel can be further improved when the panel is attached to the first vertical frame and the second vertical frame.

In the above wall construction method, the panel may be attached to the vertical frame by the magnetic force of a magnet. In this wall construction method, the panel is attached to the vertical frame by the magnetic force of a magnet, so that the panel can be easily attached and detached from the vertical frame.

The present invention allows panels to be stably installed on walls without damaging the ceiling.

The wall structure and the construction method of the wall structure according to the embodiment will be described in detail below with reference to the drawings. Note that the same or corresponding parts are given the same reference numerals in all the drawings, and duplicate explanations will be omitted.

[First embodiment]
1 to 3, the wall structure according to this embodiment is a wall structure in which a panel 5 is installed on an existing wall 1, or a wall structure for installing a panel 5 on an existing wall 1. In the following description, the up-down direction refers to the up-down direction in the wall structure. The wall 1 stands vertically from a floor 2, and a baseboard 3 is attached to the lower end of the wall 1.

The wall structure according to this embodiment includes a wall 1, a support 4, and a panel set 6 made up of a plurality of panels 5. However, the wall structure may include a single panel 5 instead of the panel set 6 made up of a plurality of panels 5. The wall 1 is a wall of a building that rises vertically from the floor 2. A baseboard 3 that rises vertically from the floor 2 is attached to the lower end of the wall 1.

As shown in FIG. 1(a), a plurality of screw holes 7 are formed in the wall 1. In this embodiment, the plurality of screw holes 7 are arranged in a horizontal row at equal intervals at a predetermined height position on the upper part of the wall 1. In other words, a plurality of screw holes 7 are formed in the wall 1 in the horizontal direction, but only one screw hole 7 is formed in the wall 1 in the vertical direction. However, a plurality of screw holes 7 may be formed in the vertical direction. The vertical direction is also referred to as the up-down direction, the vertical direction, etc.

As shown in FIG. 1(b), each screw hole 7 is formed, for example, by an anchor 8 embedded in the wall 1. The anchor 8 is an embedded anchor that is embedded in the wall 1 when the wall 1 is constructed, and has a screw hole 9 formed on its inner peripheral surface. The anchor 8 is embedded in the wall 1 while being coupled to, for example, a stud (not shown).

As shown in Figures 2 and 3, the support 4 is a member that is attached to the wall 1 and to which the panel set 6 is attached. The support 4 includes a first vertical frame 11, a second vertical frame 12, an upper horizontal frame 13, a middle horizontal frame 14, a middle horizontal frame 15, and a lower horizontal frame 16.

Each of the first vertical frame 11, the second vertical frame 12, the upper horizontal frame 13, the middle horizontal frame 14, the middle horizontal frame 15, and the lower horizontal frame 16 includes a material that can be attracted by magnetic force. In other words, each of these frames may be entirely made of a ferromagnetic material that is attracted by magnetic force, or may be partially made of such a ferromagnetic material. Also, each of these frames may be entirely made of a magnet, or may be partially made of a magnet. In addition, a form in which a portion is made of a magnet may be a form in which a portion of the frame itself is made of a magnet, or a form in which a magnet is provided on the panel attraction surface of a frame made of a material other than a magnet. The panel attraction surface of the frame is the surface on which the panel 5 is placed (attracted). Also, a magnet may be provided on the entire panel attraction surface side of the frame, or a magnet may be provided on a portion of the panel attraction surface side.

The first vertical frame 11 and the second vertical frame 12 are members that serve as supports for the support body 4. Each of the first vertical frame 11 and the second vertical frame 12 is formed in a straight line and extends in the vertical direction. The first vertical frame 11 and the second vertical frame 12 are arranged side by side in the horizontal direction. The horizontal cross section of each of the first vertical frame 11 and the second vertical frame 12 is formed in a C-shape (see Figure 4). The horizontal cross section is a horizontal cross section that is perpendicular to the vertical direction in which the first vertical frame 11 and the second vertical frame 12 extend.

As shown in Figs. 6 and 7, a notch 11a is formed at the lower end of the first vertical frame 11, which corresponds to the baseboard 3 installed on the wall 1. A large-area grounding portion 11b is formed at the lower end of the first vertical frame 11 to ensure stable grounding against the floor 2. A notch 12a is formed at the lower end of the second vertical frame 12, which corresponds to the baseboard 3 installed on the wall 1. A large-area grounding portion 12b is formed at the lower end of the second vertical frame 12 to ensure stable grounding against the floor 2. A resin elastomer such as elastic polyurethane may be provided at the lower part of the grounding portion 11b and the lower part of the grounding portion 12b to increase the frictional resistance against the floor 2 and improve installation stability, or a protective material such as felt material to protect the floor surface may be provided.

A vertical long hole 11f, a screw hole 11g, a screw hole 11h, and a screw hole 11i are formed in the side wall of the first vertical frame 11 on the side of the second vertical frame 12. The screw hole 11g is located below the vertical long hole 11f, the screw hole 11h is located below the screw hole 11g, and the screw hole 11i is located below the screw hole 11h. In addition, a vertical long hole 12f, a screw hole 12g, a screw hole 12h, and a screw hole 12i are formed in the side wall of the second vertical frame 12 on the side of the first vertical frame 11. The screw hole 12g is located below the vertical long hole 12f, the screw hole 12h is located below the screw hole 12g, and the screw hole 12i is located below the screw hole 12h.

As shown in Figures 2 and 4 to 7, the vertical long holes 11f and 12f are long holes that are long in the vertical direction, into which the connection screws 18 that connect the upper horizontal frame 13 to the first vertical frame 11 or the second vertical frame 12 are inserted. The screw holes 11g and 12g are screw holes into which the connection screws 19a that connect the middle horizontal frame 14 to the first vertical frame 11 or the second vertical frame 12 are screwed. The screw holes 11h and 12h are screw holes into which the connection screws 19b that connect the middle horizontal frame 15 to the first vertical frame 11 or the second vertical frame 12 are screwed. The screw holes 11i and 12i are screw holes into which the connection screws 19c that connect the lower horizontal frame 16 to the first vertical frame 11 or the second vertical frame 12 are screwed.

The first vertical frame 11 and the second vertical frame 12 are each constructed by connecting a plurality of segments from the viewpoint of ease of transportation. The first vertical frame 11 includes a first vertical frame segment 11c and a first vertical frame segment 11d that extend in a straight line, and a fastening member 11e such as a screw that connects the first vertical frame segment 11c and the first vertical frame segment 11d. The first vertical frame 11 is constructed by connecting the first vertical frame segment 11c and the first vertical frame segment 11d with the fastening member 11e. The second vertical frame 12 includes a second vertical frame segment 12c and a second vertical frame segment 12d that extend in a straight line, and a fastening member 12e such as a screw that connects the second vertical frame segment 12c and the second vertical frame segment 12d. The second vertical frame 12 is constructed by connecting the second vertical frame segment 12c and the second vertical frame segment 12d with the fastening member 12e.

The upper horizontal frame 13, middle horizontal frame 14, middle horizontal frame 15, and lower horizontal frame 16 are each members that extend horizontally and are connected to the first vertical frame 11 and the second vertical frame 12. In other words, the upper horizontal frame 13, middle horizontal frame 14, middle horizontal frame 15, and lower horizontal frame 16 are each connected so as to span the first vertical frame 11 and the second vertical frame 12. The middle horizontal frame 14 is disposed below the upper horizontal frame 13, the middle horizontal frame 15 is disposed below the middle horizontal frame 14, and the lower horizontal frame 16 is disposed below the middle horizontal frame 15.

As shown in Figures 2 and 8, the upper horizontal frame 13 has a first connection portion 13a, a second connection portion 13b, a first fastening portion 13c, a second fastening portion 13d, and an intermediate portion 13e.

The first connection part 13a is located at one end of the upper horizontal frame 13 and is connected to the first vertical frame 11. The horizontal cross section of the first connection part 13a is formed in a C-shape corresponding to the first vertical frame 11 (see FIG. 4). The first connection part 13a is fitted into the first vertical frame 11 so that it can slide up and down relative to the first vertical frame 11.

The second connection part 13b is located at the end of the upper horizontal frame 13 opposite to the first connection part 13a, and is connected to the second vertical frame 12. The horizontal cross section of the second connection part 13b is formed in a C-shape corresponding to the second vertical frame 12. The second connection part 13b is fitted into the second vertical frame 12 so that it can slide up and down relative to the second vertical frame 12.

The side wall of the first connection part 13a facing the second connection part 13b and the side wall of the second connection part 13b facing the first connection part 13a each have a connection screw hole 13h into which a connection screw 18 is screwed to connect the upper horizontal frame 13 to the first vertical frame 11 or the second vertical frame 12.

The first fastening portion 13c is a portion that abuts against the wall 1 and is fastened to the wall 1. The first fastening portion 13c is connected to the second connection portion 13b side of the first connection portion 13a. The first fastening portion 13c has a horizontal slot 13f into which a fastening screw 17 (see Figures 2 and 4) is inserted to fasten the upper horizontal frame 13 to the wall 1. The horizontal slot 13f is a slot that is long in the horizontal direction. The fastening screw 17 is inserted into the horizontal slot 13f and then screwed into the screw hole 7 formed in the wall 1, thereby fastening the upper horizontal frame 13 to the wall 1.

The second fastening portion 13d is a portion that abuts against the wall 1 and is fastened to the wall 1. The second fastening portion 13d is connected to the first connection portion 13a side of the second connection portion 13b. The second fastening portion 13d is formed with a horizontal elongated hole 13g into which a fastening screw 17 (see FIG. 2) is inserted to fasten the upper horizontal frame 13 to the wall 1. The horizontal elongated hole 13g is a long hole that is long in the horizontal direction. The fastening screw 17 is inserted into the horizontal elongated hole 13g and screwed into the screw hole 7 formed in the wall 1 to fasten the upper horizontal frame 13 to the wall 1.

The intermediate portion 13e is a portion that connects the first fastening portion 13c and the second fastening portion 13d. The intermediate portion 13e is bent with respect to the first fastening portion 13c and the second fastening portion 13d to increase the rigidity of the upper horizontal frame 13. Therefore, the intermediate portion 13e is spaced apart from the wall 1.

Here, the upper horizontal frame 13 is fastened to the wall 1 by fastening screws 17, and is connected to the first vertical frame 11 and the second vertical frame 12 by connecting screws 18. In other words, the first vertical frame 11 and the second vertical frame 12 are indirectly fastened to the wall 1 via the upper horizontal frame 13, fastening screws 17, and connecting screws 18. Therefore, the upper horizontal frame 13, fastening screws 17, and connecting screws 18 constitute a fastening mechanism that indirectly fastens the first vertical frame 11 and the second vertical frame 12 to the wall 1.

When connecting the upper horizontal frame 13 to the first vertical frame 11 or the second vertical frame 12, the connection screw 18 is inserted into the vertical long hole 11f of the first vertical frame 11 and the vertical long hole 12f of the second vertical frame 12. Since the vertical long hole 11f and the vertical long hole 12f are long holes that are long in the vertical direction, the fastening position of the vertical long hole 11f and the vertical long hole 12f relative to the connection screw 18 can be changed in the vertical direction. As a result, after fastening the upper horizontal frame 13 to the wall 1, the first vertical frame 11 and the second vertical frame 12 can be braced against the floor 2 by adjusting the fastening position of the vertical long hole 11f and the vertical long hole 12f relative to the connection screw 18. Therefore, the upper horizontal frame 13, the fastening screw 17, the connection screw 18, the vertical long hole 11f, and the vertical long hole 12f constitute a bracing mechanism that braces the first vertical frame 11 and the second vertical frame 12 against the floor 2.

In addition, since the horizontal long holes 13f and 13g are long holes that are long in the horizontal direction, the positions of the horizontal long holes 13f and 13g relative to the fastening screws 17 can be changed. This allows the fastening position of the upper horizontal frame 13 to be adjusted horizontally.

As shown in Figures 2 and 9, the middle horizontal frame 14 has a first connection portion 14a, a second connection portion 14b, a first abutment portion 14c, a second abutment portion 14d, and an intermediate portion 14e.

The first connection portion 14a is located at one end of the middle horizontal frame 14 and is connected to the first vertical frame 11. The first connection portion 14a is formed in a flat plate shape parallel to the side wall of the first vertical frame 11 on the second vertical frame 12 side. The second connection portion 14b is located at the end of the middle horizontal frame 14 opposite the first connection portion 14a and is connected to the second vertical frame 12. The second connection portion 14b is formed in a flat plate shape parallel to the side wall of the second vertical frame 12 on the first vertical frame 11 side. Each of the first connection portion 14a and the second connection portion 14b has a through hole 14f into which a connection screw 19a is inserted to connect the middle horizontal frame 14 to the first vertical frame 11 or the second vertical frame 12.

The first abutment portion 14c is connected to the second connection portion 14b side of the first connection portion 14a and abuts against the wall 1. The second abutment portion 14d is connected to the first connection portion 14a side of the second connection portion 14b and abuts against the wall 1. Note that the first abutment portion 14c and the second abutment portion 14d do not have holes formed therein that correspond to the horizontal long holes 13f and 13g of the upper horizontal frame 13.

The intermediate portion 14e is a portion that connects the first abutment portion 14c and the second abutment portion 14d. The intermediate portion 14e is bent with respect to the first abutment portion 14c and the second abutment portion 14d in order to increase the rigidity of the middle horizontal frame 14. Therefore, the intermediate portion 14e is spaced apart from the wall 1. The intermediate portion 14e has a slit 14g that extends horizontally. The slit 14g is a notch that is formed in the intermediate portion 14e to hook the panel 5. The slit 14g crosses the intermediate portion 14e in the horizontal direction. In other words, the slit 14g extends from the tip of the intermediate portion 14e on the first abutment portion 14c side to the tip of the intermediate portion 14e on the second abutment portion 14d side. However, the slit 14g does not have to cross the intermediate portion 14e in the horizontal direction, and may be formed only in a part of the intermediate portion 14e.

The middle horizontal frame 15 has the same configuration as the middle horizontal frame 14. That is, the middle horizontal frame 15 includes a first connection portion 15a corresponding to the first connection portion 14a, a second connection portion 15b corresponding to the second connection portion 14b, a first abutment portion 15c corresponding to the first abutment portion 14c, a second abutment portion 15d corresponding to the second abutment portion 14d, and an intermediate portion 15e corresponding to the intermediate portion 14e. A through hole 15f corresponding to the through hole 14f is formed in each of the first connection portion 15a and the second connection portion 15b. A slit 15g corresponding to the slit 14g is formed in the intermediate portion 15e. Note that a connection screw 19b that connects the middle horizontal frame 15 to the first vertical frame 11 or the second vertical frame 12 is inserted into the through hole 15f.

2 and 10, the lower horizontal frame 16 has the same basic structure as the middle horizontal frame 14, and differs from the middle horizontal frame 14 only in that the slit 14g of the middle horizontal frame 14 is not formed. That is, the lower horizontal frame 16 includes a first connecting portion 16a corresponding to the first connecting portion 14a, a second connecting portion 16b corresponding to the second connecting portion 14b, a first abutting portion 16c corresponding to the first abutting portion 14c, a second abutting portion 16d corresponding to the second abutting portion 14d, and an intermediate portion 16e corresponding to the intermediate portion 14e. A through hole 16f corresponding to the through hole 14f is formed in each of the first connecting portion 16a and the second connecting portion 16b. Note that a connection screw 19c that connects the lower horizontal frame 16 to the first vertical frame 11 or the second vertical frame 12 is inserted into the through hole 16f. Also, a notch corresponding to the slit 14g of the middle horizontal frame 14 is not formed in the intermediate portion 16e.

As described above, the panel set 6 is made up of multiple panels 5, but in this embodiment, it will be described as being made up of an upper panel 51, a middle panel 52, and a lower panel 53. The upper panel 51 is the panel that is positioned at the top of the panel set 6, the middle panel 52 is the panel that is positioned below the upper panel 51, and the lower panel 53 is the panel that is positioned below the middle panel 52 and is the lowest panel in the panel set 6.

As shown in Figures 3, 11(a), and 12(a), the upper panel 51 includes a panel body 51a and a hook portion 51b.

The panel body 51a is a member that is attached to the support body 4. By being attached to the support body 4, the panel body 51a becomes part of the interior of a space such as a room.

The panel body 51a includes a material that can be attracted by magnetic force. In other words, the entire panel body 51a may be made of a ferromagnetic material, or only a part of the panel body 51a may be made of a ferromagnetic material. Also, the entire panel body 51a may be made of a magnet, or only a part of the panel body 51a may be made of a magnet.

The panel body 51a is formed in a thin rectangular plate shape. The panel body 51a can be manufactured, for example, by fitting a pair of box-shaped members, each of which is formed by folding the four sides of a rectangular plate, together so that the front surface 51c side is covered by the back surface 51d side, and filling the inside with a core material such as urethane foam. This allows the edges of the front surface 51c side of the panel body 51a to be rounded, and the weight of the panel body 51a to be reduced. In this case, for example, if the pair of box-shaped members are made of a ferromagnetic material, the panel body 51a can be attracted by magnetic force. Of the front and back surfaces of the panel body 51a, the front surface 51c is the surface facing the opposite side of the wall 1 of the panel body 51a, and the back surface 51d is the surface facing the wall 1 side of the panel body 51a (the surface on the support body 4 side).

The hook portion 51b is a member for hooking the upper panel 51 to the upper horizontal frame 13. The hook portion 51b is fixed to the upper center of the back surface 51d of the panel main body 51a, and extends in a hook shape (key shape) from the back surface 51d. Therefore, by hooking the hook portion 51b to the upper horizontal frame 13 from above, it is possible to hook the upper panel 51 to the middle portion 13e of the upper horizontal frame 13. There may be only one hook portion 51b, or multiple hook portions 51b.

As shown in Figures 3, 11(b), and 12(b), the middle panel 52 is basically the same as the upper panel 51, and differs from the upper panel 51 only in that it has a hook portion 52b instead of the hook portion 51b. That is, the middle panel 52 has a panel body 52a corresponding to the panel body 51a, and a hook portion 52b. Of the front and back surfaces of the panel body 52a, the front surface 52c is the surface of the panel body 52a facing away from the wall 1, and the back surface 52d is the surface of the panel body 52a facing the wall 1 side (the surface on the support body 4 side).

The hook portion 52b is a member for hooking the middle panel 52 to the middle horizontal frame 14. The hook portion 52b is fixed to the upper center of the back surface 52d of the panel main body 52a, and extends horizontally from the back surface 52d in a flat (straight) shape. The thickness of the hook portion 52b is thinner than the width of the slit 14g. Therefore, by inserting the hook portion 52b into the slit 14g, it is possible to hook the middle panel 52 to the intermediate portion 14e of the middle horizontal frame 14. There may be only one hook portion 52b, or multiple hook portions 52b.

3, 11(c), and 12(c), the lower panel 53 has the same configuration as the middle panel 52. That is, the lower panel 53 has a panel body 53a corresponding to the panel body 52a, and a hooking portion 53b corresponding to the hooking portion 52b. Of the front and back surfaces of the panel body 53a, the front surface 53c is the surface of the panel body 53a facing away from the wall 1, and the back surface 53d is the surface of the panel body 53a facing the wall 1 (the surface on the support body 4 side). The hooking portion 53b is a member for hooking the lower panel 53 to the middle horizontal frame 15, and by inserting it into the slit 15g of the middle horizontal frame 15, the lower panel 53 can be hooked to the intermediate portion 15e of the middle horizontal frame 15.

In the wall structure thus constructed, the upper horizontal frame 13 is fastened to the wall 1 by the fastening screws 17, the first vertical frame 11 and the second vertical frame 12 are connected to the upper horizontal frame 13 by the connecting screws 18, and the middle horizontal frame 14, the middle horizontal frame 15, and the lower horizontal frame 16 are connected to the first vertical frame 11 and the second vertical frame 12 to form the support body 4. Therefore, the first vertical frame 11 and the second vertical frame 12 are indirectly fastened to the wall 1 via the upper horizontal frame 13, the fastening screws 17, and the connecting screws 18. The fastening positions of the vertical long holes 11f and the vertical long holes 12f relative to the connecting screws 18 are adjusted so that the first vertical frame 11 and the second vertical frame 12 are braced against the floor 2.

The upper panel 51, middle panel 52, and lower panel 53 are attached to the support 4 by magnets 21 (see FIG. 18). The upper panel 51 is attached to the support 4 by hooking the hook portion 51b onto the upper horizontal frame 13 and by magnetic attraction of the magnet 21. The middle panel 52 is attached to the support 4 by inserting the hook portion 52b into the slit 14g and by magnetic attraction of the magnet 21. The lower panel 53 is attached to the support 4 by inserting the hook portion 53b into the slit 15g and by magnetic attraction of the magnet 21.

The magnet 21 is attracted by the magnetic force of a magnetic sheet or the like. The magnet 21 may be attached to the upper panel 51, the middle panel 52, and the lower panel 53 and the support 4 only by the magnetic attraction of the magnet 21, or may be attached to the upper panel 51, the middle panel 52, and the lower panel 53 and the support 4 by other means such as magnetic attraction and adhesion of the magnet 21. In the latter case, for example, the magnet 21 may be adhered to the upper panel 51, the middle panel 52, and the lower panel 53, or may be adhered to the support 4. Note that the magnet 21 is preferably attached to all frames constituting the support 4, but may be attached to only some of the frames constituting the support 4 as long as the upper panel 51, the middle panel 52, and the lower panel 53 can be attached to the support 4.

Next, we will explain the construction method for the wall structure according to this embodiment.

First, as shown in FIG. 13, the upper horizontal frame 13 is fastened to the wall 1. When fastening the upper horizontal frame 13 to the wall 1, the fastening screws 17 are screwed into the screw holes 7 formed in the wall 1 through the horizontal long holes 13f and 13g. At this time, by adjusting the fastening positions of the horizontal long holes 13f and 13g relative to the fastening screws 17, horizontal positional deviation of the screw holes 7 formed in the wall 1 can be tolerated.

Next, as shown in FIG. 14, the first vertical frame 11 and the second vertical frame 12 are connected to the upper horizontal frame 13. When connecting the first vertical frame 11 and the second vertical frame 12 to the upper horizontal frame 13, the first vertical frame 11 and the second vertical frame 12 are placed over the first connecting portion 13a and the second connecting portion 13b, and the first connecting portion 13a and the second connecting portion 13b are fitted into the first vertical frame 11 and the second vertical frame 12. Then, the connection screws 18 are screwed from the vertical long holes 11f of the first vertical frame 11 and the vertical long holes 12f of the second vertical frame 12 into the connection screw holes 13h of the first connecting portion 13a and the second connecting portion 13b. As a result, the first vertical frame 11 and the second vertical frame 12 are indirectly fastened to the wall 1 via the upper horizontal frame 13, the fastening screws 17, and the connection screws 18.

At this time, the fastening positions of the vertical elongated holes 11f and 12f relative to the connection screws 18 are adjusted so that the first vertical frame 11 and the second vertical frame 12 are braced against the floor 2. This causes the first vertical frame 11 and the second vertical frame 12 to be braced against the floor 2.

15 and 16, the middle horizontal frame 14, middle horizontal frame 15, and lower horizontal frame 16 are connected to the first vertical frame 11 and the second vertical frame 12. When connecting the middle horizontal frame 14 to the first vertical frame 11 and the second vertical frame 12, the connection screws 19a are screwed from the through holes 14f of the first connection portion 14a and the second connection portion 14b into the screw holes 11g of the first vertical frame 11 and the screw holes 12g of the second vertical frame 12. When connecting the middle horizontal frame 15 to the first vertical frame 11 and the second vertical frame 12, the connection screws 19b are screwed from the through holes 15f of the first connection portion 15a and the second connection portion 15b into the screw holes 11h of the first vertical frame 11 and the screw holes 12h of the second vertical frame 12. When connecting the lower horizontal frame 16 to the first vertical frame 11 and the second vertical frame 12, the connection screws 19c are screwed from the through holes 16f of the first connection portion 16a and the second connection portion 16b into the screw holes 11i of the first vertical frame 11 and the screw holes 12i of the second vertical frame 12. This makes the support 4 a frame structure, increasing the rigidity of the support 4.

Next, as shown in FIG. 17, magnets 21 are attached to each of the first vertical frame 11, the second vertical frame 12, the upper horizontal frame 13, the middle horizontal frame 14, the middle horizontal frame 15, and the lower horizontal frame 16. The magnets 21 are attracted by the magnetic force of a magnetic sheet or the like. The magnets 21 may be attached to each of the first vertical frame 11, the second vertical frame 12, the upper horizontal frame 13, the middle horizontal frame 14, the middle horizontal frame 15, and the lower horizontal frame 16 by, for example, magnetic attraction of the magnets 21 or by adhesion. At this time, the magnets 21 are attached to the middle horizontal frame 14 and the middle horizontal frame 15 so that the slits 14g and 15g are not hidden. This completes the construction of the support body 4.

The magnets 21 may be attached in advance to each of the first vertical frame 11, the second vertical frame 12, the upper horizontal frame 13, the middle horizontal frame 14, the middle horizontal frame 15, and the lower horizontal frame 16.

18 and 19, the upper panel 51, the middle panel 52, and the lower panel 53 are attached to the support 4. When attaching the upper panel 51 to the support 4, the hook portion 51b of the upper panel 51 is hooked onto the upper horizontal frame 13, and the panel body 51a of the upper panel 51 is attracted to the magnet 21 attached to the support 4. When attaching the middle panel 52 to the support 4, the hook portion 52b of the middle panel 52 is inserted into the slit 14g of the middle horizontal frame 14, and the panel body 52a of the middle panel 52 is attracted to the magnet 21 attached to the support 4. When attaching the lower panel 53 to the support 4, the hook portion 53b of the lower panel 53 is inserted into the slit 15g of the middle horizontal frame 15, and the panel body 53a of the lower panel 53 is attracted to the magnet 21 attached to the support 4. This results in a panel set 6 consisting of an upper panel 51, a middle panel 52, and a lower panel 53 being attached to the wall 1.

Here, the upper panel 51, the middle panel 52, and the lower panel 53 contain materials that can be attracted by magnetic force. Therefore, as shown in FIG. 20, various items that can be attracted by magnetic force, such as shelves, ornaments, and frames, can be attached to the panel set 6. For example, a magnetic suction shelf 30 as shown in FIG. 21 can be attracted to the panel set 6.

The magnetic suction shelf 30 shown in FIG. 21 is a box having a back panel 31, side panels 32 that stand up like a frame from the back panel 31, and a magnet 33 joined to the back panel 31. The magnetic suction shelf 30 is divided into a number of divisions 34, 35, 36, and 37. Each of the divisions 34, 35, 36, and 37 includes at least a portion of the back panel 31, a portion of the side panels 32, and a portion of the magnet 33. As shown in FIG. 22, the divisions 34 and 37 include a portion of the back panel 31, a portion of the side panels 32 on two sides, and a portion of the magnet 33. As shown in FIG. 23, the divisions 35 and 36 include a portion of the back panel 31, a portion of the side panel 32 on one side, and a portion of the magnet 33. In such a magnetic suction shelf 30, each of the divided bodies 34, 35, 36, and 37 can be freely arranged on the panel set 6, so the divided bodies 34, 35, 36, and 37 can be used as a shelf combined with a box body, and each of the divided bodies 34, 35, 36, and 37 can also be used as a shelf.

In this embodiment, the upper horizontal frame 13, fastening screws 17, and connecting screws 18 functioning as a fastening mechanism fasten the first vertical frame 11 and the second vertical frame 12 to the wall 1, and the upper horizontal frame 13, fastening screws 17, connecting screws 18, vertical long holes 11f, and vertical long holes 12f functioning as a tension mechanism tension the first vertical frame 11 and the second vertical frame 12 against the floor 2. This allows the first vertical frame 11 and the second vertical frame 12 to be stably installed on the wall 1 without abutting the first vertical frame 11 and the second vertical frame 12 against the ceiling. Therefore, by attaching the panel 5 to the first vertical frame 11 and the second vertical frame 12 installed on the wall 1, the panel 5 can be stably installed on the wall 1 without damaging the ceiling.

In addition, because the first vertical frame 11 and the second vertical frame 12 are fastened to the screw holes 7 formed in the wall 1, the panel 5 can be stably installed on the wall 1 without damaging the wall 1. Moreover, even if there is only one screw hole 7 formed in the wall 1 in the vertical direction, the panel 5 can be stably installed on the wall 1.

The first vertical frame 11 and the second vertical frame 12 are fastened to the wall 1 via the upper horizontal frame 13, fastening screws 17, and connection screws 18, and are arranged side by side in the horizontal direction. This improves the stability of the panel 5 when the panel 5 is attached to the first vertical frame 11 and the second vertical frame 12.

In addition, since the upper horizontal frame 13 has horizontal long holes 13f and 13g that extend horizontally and into which the fastening screws 17 are inserted, the position of the upper horizontal frame 13 relative to the wall 1 can be adjusted horizontally when the fastening screws 17 are screwed into the wall 1. Therefore, for example, even if the horizontal positional accuracy of the screw holes 7 formed in the wall 1 is poor, the first vertical frame 11 and the second vertical frame 12 can be fastened to the wall 1.

In addition, since the upper horizontal frame 13 has a connection screw hole 13h into which the connection screw 18 is screwed, and the first vertical frame 11 and the second vertical frame 12 have vertical long holes 11f and 12f that extend vertically and into which the connection screw 18 is inserted, the positions of the first vertical frame 11 and the second vertical frame 12 relative to the upper horizontal frame 13 can be adjusted vertically when the connection screw 18 is screwed into the connection screw hole 13h. Therefore, after fastening the upper horizontal frame 13 to the wall 1, the first vertical frame 11 and the second vertical frame 12 can be braced against the floor 2 by adjusting the fastening positions of the vertical long holes 11f and 12f relative to the connection screw 18. In addition, even if the vertical positional accuracy of the screw holes 7 formed in the wall 1 is poor, the first vertical frame 11 and the second vertical frame 12 can be fastened to the wall 1.

In addition, the middle horizontal frames 14 and 15, which are arranged to extend horizontally below the upper horizontal frame 13, are connected to the first vertical frame 11 and the second vertical frame 12, so that the support body 4 can be configured in a frame shape. This increases the rigidity of the support body 4 and prevents the positional relationship between the first vertical frame 11 and the second vertical frame 12 from shifting.

In addition, slits 14g and 15g for hanging the panel 5 are formed in the middle horizontal frame 14 and the middle horizontal frame 15, so the panel 5 can be easily installed by hanging the panel 5 in the slits 14g and 15g.

In addition, because each frame that constitutes the support 4 contains a ferromagnetic material, the panel 5 can be attracted to each frame of the support 4 by the magnet 21, and the panel 5 can be easily attached and detached to each frame of the support 4.

In addition, the panel 5 can be easily installed by hooking the hook portions 51b, 52b, and 53b of the panel 5 to the upper horizontal frame 13, middle horizontal frame 14, and middle horizontal frame 15 of the support body 4.

[Second embodiment]
Next, a second embodiment will be described. The second embodiment is basically the same as the first embodiment, and differs from the first embodiment only in that slits are formed in the first vertical frame and the second vertical frame, that the middle horizontal frame is not provided, and that the hooking portions of the middle panel and the lower panel are different. Therefore, only the differences from the first embodiment will be described below, and the same matters as the first embodiment will be omitted.

As shown in Figures 24 and 25, the support 4A of the wall structure according to the second embodiment includes a first vertical frame 11a, a second vertical frame 12a, an upper horizontal frame 13, and a lower horizontal frame 16. Note that the support 4A does not include members corresponding to the middle horizontal frame 14 and the middle horizontal frame 15 of the first embodiment.

The first vertical frame 11a and the second vertical frame 12a are basically the same as the first vertical frame 11 and the second vertical frame 12 of the first embodiment, but in the first embodiment, slits 11j and 12j are formed at the position where the middle horizontal frame 14 is connected, and in the first embodiment, slits 11k and 12k are formed at the position where the middle horizontal frame 15 is connected.

Slits 11j and 11k are notches formed in the first vertical frame 11a to hang the panel 5. Slits 11j and 11k cross the first vertical frame 11a in the horizontal direction. However, slits 11j and 11k do not have to cross the first vertical frame 11a in the horizontal direction, and may be formed only in a part of the first vertical frame 11a.

Slits 12j and 12k are notches formed in the second vertical frame 12a to hang the panel 5. Slits 12j and 12k cross the second vertical frame 12a in the horizontal direction. However, slits 12j and 12k do not have to cross the second vertical frame 12a in the horizontal direction, and may be formed only in a part of the second vertical frame 12a.

The panel set of the wall structure according to the second embodiment consists of an upper panel 51 (see Figures 11(a) and 12(a)), a middle panel 52A, and a lower panel 53A.

As shown in FIG. 26, the middle panel 52A is basically the same as the middle panel 52 of the first embodiment, and differs from the middle panel 52 of the first embodiment only in that a pair of hooks 52b are fixed to both upper ends of the back surface 52d of the panel body 52a. The pair of hooks 52b are members for hooking the middle panel 52A to the first vertical frame 11a and the second vertical frame 12a, and are fixed at positions corresponding to the slits 11j of the first vertical frame 11a and the slits 12j of the second vertical frame 12a.

The lower panel 53A is basically the same as the lower panel 53 of the first embodiment, and differs from the lower panel 53 of the first embodiment only in that a pair of hooks 53b are fixed to both upper ends of the back surface 53d of the panel body 53a. The pair of hooks 53b are members for hooking the lower panel 53A to the first vertical frame 11a and the second vertical frame 12a, and are fixed at positions corresponding to the slits 11k of the first vertical frame 11a and the slits 12k of the second vertical frame 12a.

In the wall structure thus constructed, the upper horizontal frame 13 is fastened to the wall 1 by the fastening screws 17, the first vertical frame 11a and the second vertical frame 12a are connected to the upper horizontal frame 13 by the connecting screws 18, and the lower horizontal frame 16 is connected to the first vertical frame 11a and the second vertical frame 12a to form the support body 4A. Therefore, the first vertical frame 11a and the second vertical frame 12a are indirectly fastened to the wall 1 via the upper horizontal frame 13, the fastening screws 17, and the connecting screws 18. The fastening positions of the vertical long holes 11f and the vertical long holes 12f relative to the connecting screws 18 are adjusted so that the first vertical frame 11a and the second vertical frame 12a are braced against the floor 2.

The upper panel 51, middle panel 52A, and lower panel 53A are attached to the support 4A by magnets 21 (see FIG. 18). The upper panel 51 is attached to the support 4 by hooking the hook portions 51b onto the upper horizontal frame 13 and by magnetic attraction of the magnets 21. The middle panel 52A is attached to the support 4A by inserting a pair of hook portions 52b into slits 11j and 12j and by magnetic attraction of the magnets 21. The lower panel 53A is attached to the support 4A by inserting a pair of hook portions 53b into slits 11k and 12k and by magnetic attraction of the magnets 21.

When constructing a wall structure configured in this manner, first, as in the first embodiment, the upper horizontal frame 13 is fastened to the wall 1, the first vertical frame 11a and the second vertical frame 12a are connected to the upper horizontal frame 13, and the lower horizontal frame 16 is connected to the first vertical frame 11a and the second vertical frame 12a. Magnets 21 are then attached to each of the first vertical frame 11a, the second vertical frame 12a, the upper horizontal frame 13, and the lower horizontal frame 16. This completes the construction of the support body 4A.

Next, as in the first embodiment, the upper panel 51, the middle panel 52A, and the lower panel 53A are attached to the support 4A. When attaching the middle panel 52A to the support 4A, the pair of hooks 52b of the middle panel 52A are inserted into the slits 11j of the first vertical frame 11a and the slits 12j of the second vertical frame 12a, and the middle panel 52A is attracted to the magnet 21 attached to the support 4A. When attaching the lower panel 53A to the support 4A, the pair of hooks 53b of the lower panel 53A are inserted into the slits 11k of the first vertical frame 11a and the slits 12k of the second vertical frame 12a, and the lower panel 53A is attracted to the magnet 21 attached to the support 4A. This results in a panel set consisting of the upper panel 51, the middle panel 52A, and the lower panel 53A being attached to the wall 1.

In this manner, in this embodiment, the first vertical frame 11a and the second vertical frame 12a are formed with slits 11j and 12j for hanging the middle panel 52A, and slits 11k and 12k for hanging the lower panel 53A. By hanging the middle panel 52A and the lower panel 53A in the slits, the middle panel 52A and the lower panel 53A can be easily installed.

In this embodiment, the pair of hook portions 51b of the upper panel 51 are fixed to both upper ends of the back surface 51d of the panel body 51a in the same manner as the middle panel 52A and the lower panel 53A, and openings may be formed at the top of the first vertical frame 11a and the second vertical frame 12a, and the pair of hook portions 51b of the upper panel 51 may be hooked onto the openings at the top of the first vertical frame 11a and the second vertical frame 12a.

[Third embodiment]
Next, a third embodiment will be described. The third embodiment is basically the same as the first embodiment, and differs from the first embodiment only in that no slits are formed in the middle horizontal frame and that the hooking portions of the middle panel and the lower panel are different. Therefore, only the differences from the first embodiment will be described below, and the same matters as the first embodiment will be omitted.

As shown in FIG. 27, the support 4B of the wall structure according to the third embodiment includes a first vertical frame 11, a second vertical frame 12, an upper horizontal frame 13, a middle horizontal frame 14B, a middle horizontal frame 15B, and a lower horizontal frame 16.

The middle horizontal frame 14B and the middle horizontal frame 15B are the same as the middle horizontal frame 14 and the middle horizontal frame 15 of the first embodiment, except that they do not have notches corresponding to the slits 14g and 15g of the first embodiment.

The panel set of the wall structure according to the third embodiment consists of an upper panel 51 (see Figures 11(a) and 12(a)), a middle panel 52B, and a lower panel 53B.

As shown in FIG. 28, the middle panel 52B is basically the same as the middle panel 52 of the first embodiment, and differs from the middle panel 52 of the first embodiment only in that it has a hook portion 52e instead of the hook portion 52b. The hook portion 52e is a member for hooking the middle panel 52B to the middle horizontal frame 14B. The hook portion 52e has the same configuration as the hook portion 51b of the upper panel 51. The hook portion 52e is fixed to the upper center of the back surface 52d of the panel main body 52a, and is hooked to the intermediate portion 14e of the middle horizontal frame 14B.

The lower panel 53B is basically the same as the lower panel 53 of the first embodiment, and differs from the lower panel 53 of the first embodiment only in that it has a hook portion 53e instead of the hook portion 53b. The hook portion 53e is a member for hooking the lower panel 53B to the middle horizontal frame 15B. The hook portion 53e has the same configuration as the hook portion 51b of the upper panel 51. The hook portion 53e is fixed to the upper center of the back surface 53d of the panel main body 53a, and is hooked to the intermediate portion 15e of the middle horizontal frame 15B.

In the wall structure thus constructed, the upper horizontal frame 13 is fastened to the wall 1 by the fastening screws 17, the first vertical frame 11 and the second vertical frame 12 are connected to the upper horizontal frame 13 by the connecting screws 18, and the middle horizontal frame 14B, the middle horizontal frame 15B, and the lower horizontal frame 16 are connected to the first vertical frame 11 and the second vertical frame 12 to form the support body 4B. Therefore, the first vertical frame 11 and the second vertical frame 12 are indirectly fastened to the wall 1 via the upper horizontal frame 13, the fastening screws 17, and the connecting screws 18. The fastening positions of the vertical long holes 11f and the vertical long holes 12f relative to the connecting screws 18 are adjusted so that the first vertical frame 11 and the second vertical frame 12 are braced against the floor 2.

The upper panel 51, middle panel 52B, and lower panel 53B are attached to the support 4B by magnets 21 (see FIG. 18). The upper panel 51 is attached to the support 4B by hooking the hook portion 51b onto the upper horizontal frame 13 and by magnetic attraction of the magnet 21. The middle panel 52B is attached to the support 4B by hooking the hook portion 52e onto the middle horizontal frame 14B and by magnetic attraction of the magnet 21. The lower panel 53B is attached to the support 4B by hooking the hook portion 53e onto the middle horizontal frame 15B and by magnetic attraction of the magnet 21.

When constructing a wall structure configured in this manner, first, as in the first embodiment, the upper horizontal frame 13 is fastened to the wall 1, the first vertical frame 11 and the second vertical frame 12 are connected to the upper horizontal frame 13, and the middle horizontal frame 14B, middle horizontal frame 15B, and lower horizontal frame 16 are connected to the first vertical frame 11 and the second vertical frame 12. Then, magnets 21 are attached to each of the first vertical frame 11, the second vertical frame 12, the upper horizontal frame 13, the middle horizontal frame 14B, the middle horizontal frame 15B, and the lower horizontal frame 16. This completes the construction of the support body 4B.

Next, as in the first embodiment, the upper panel 51, the middle panel 52B, and the lower panel 53B are attached to the support 4B. When attaching the middle panel 52B to the support 4B, the hook portion 52e of the middle panel 52B is hooked onto the middle portion 14e of the middle horizontal frame 14B, and the middle panel 52B is attracted to the magnet 21 attached to the support 4B. When attaching the lower panel 53B to the support 4B, the hook portion 53e of the lower panel 53B is hooked onto the middle portion 15e of the middle horizontal frame 15B, and the lower panel 53B is attracted to the magnet 21 attached to the support 4B. This results in a panel set consisting of the upper panel 51, the middle panel 52B, and the lower panel 53B being attached to the wall 1.

[Fourth embodiment]
Next, a fourth embodiment will be described. The fourth embodiment is basically the same as the first embodiment, and differs from the first embodiment only in that no slits are formed in the middle horizontal frame and that the hooking portion of the upper panel is different. Therefore, only the differences from the first embodiment will be described below, and the same matters as the first embodiment will be omitted.

As shown in FIG. 29, the support 4C of the wall structure according to the fourth embodiment has the same configuration as the support 4B of the third embodiment (see FIG. 27). That is, the support 4C includes a first vertical frame 11 and a second vertical frame 12, an upper horizontal frame 13, a middle horizontal frame 14C having the same configuration as the middle horizontal frame 14B of the third embodiment, a middle horizontal frame 15C having the same configuration as the middle horizontal frame 15B of the third embodiment, and a lower horizontal frame 16.

The panel set for the wall structure in the fourth embodiment consists of an upper panel 51C, a middle panel 52C, and a lower panel 53C.

30, the upper panel 51C is basically the same as the upper panel 51 of the first embodiment, and differs from the upper panel 51 of the first embodiment only in that a pair of hooks 51f are fixed to both upper ends of the back surface 51d of the panel body 51a instead of the hooks 51b. The pair of hooks 51f are members for hooking the upper panel 51C to the upper end 11m of the first vertical frame 11 and the upper end 12m of the second vertical frame 12. The pair of hooks 51f are fixed at positions corresponding to the first vertical frame 11a and the second vertical frame 12a, and extend from the back surface 51d in a hook shape (key shape). Therefore, by hooking the pair of hooks 51f to the upper end 11m of the first vertical frame 11 and the upper end 12m of the second vertical frame 12 from above, it is possible to hook the upper panel 51C to the upper end 11m of the first vertical frame 11 and the upper end 12m of the second vertical frame 12.

As shown in FIG. 31, the middle panel 52C is basically the same as the middle panel 52 of the first embodiment, and differs from the middle panel 52 of the first embodiment only in that it has a hook portion 52f instead of the hook portion 52b. The hook portion 52f is a member for hooking the middle panel 52C to the middle horizontal frame 14C. The hook portion 52f is fixed to the upper center of the back surface 52d of the panel main body 52a, and extends in a hook shape (key shape) from the back surface 52d. Therefore, by hooking the hook portion 52f to the middle portion 14e of the middle horizontal frame 14C from above, it is possible to hook the middle panel 52C to the middle portion 14e of the middle horizontal frame 14C. There may be only one hook portion 52f, or multiple hook portions 52f.

The lower panel 53C is basically the same as the lower panel 53 of the first embodiment, and differs from the lower panel 53 of the first embodiment only in that it has a hook portion 53f instead of the hook portion 53b. The hook portion 53f is a member for hooking the lower panel 53C to the middle horizontal frame 15C. The hook portion 53f is fixed to the upper center of the back surface 53d of the panel main body 53a, and extends from the back surface 53d in a hook shape (key shape). Therefore, by hooking the hook portion 53f to the middle portion 15e of the middle horizontal frame 15C from above, it is possible to hook the lower panel 53C to the middle portion 15e of the middle horizontal frame 15C. There may be only one hook portion 53f, or multiple hook portions 53f.

In the wall structure thus constructed, the upper horizontal frame 13 is fastened to the wall 1 by the fastening screws 17, the first vertical frame 11 and the second vertical frame 12 are connected to the upper horizontal frame 13 by the connecting screws 18, and the middle horizontal frame 14C, the middle horizontal frame 15C, and the lower horizontal frame 16 are connected to the first vertical frame 11 and the second vertical frame 12 to form the support body 4C. Therefore, the first vertical frame 11 and the second vertical frame 12 are indirectly fastened to the wall 1 via the upper horizontal frame 13, the fastening screws 17, and the connecting screws 18. The fastening positions of the vertical long holes 11f and the vertical long holes 12f relative to the connecting screws 18 are adjusted so that the first vertical frame 11 and the second vertical frame 12 are braced against the floor 2.

The upper panel 51C, middle panel 52C, and lower panel 53C are attached to the support 4C by magnets 21 (see FIG. 18). The upper panel 51C is attached to the support 4C by hooking a pair of hooking parts 51f onto the first vertical frame 11 and the second vertical frame 12 and by magnetic attraction of the magnets 21. The middle panel 52C is attached to the support 4C by hooking a hooking part 52f onto the middle horizontal frame 14C and by magnetic attraction of the magnets 21. The lower panel 53C is attached to the support 4C by hooking a hooking part 53f onto the middle horizontal frame 15C and by magnetic attraction of the magnets 21.

When constructing a wall structure configured in this manner, first, as in the first embodiment, the upper horizontal frame 13 is fastened to the wall 1, the first vertical frame 11 and the second vertical frame 12 are connected to the upper horizontal frame 13, and the middle horizontal frame 14C, middle horizontal frame 15C, and lower horizontal frame 16 are connected to the first vertical frame 11 and the second vertical frame 12. Then, magnets 21 are attached to each of the first vertical frame 11, the second vertical frame 12, the upper horizontal frame 13, the middle horizontal frame 14C, the middle horizontal frame 15C, and the lower horizontal frame 16. This completes the construction of the support body 4C.

Next, as in the first embodiment, the upper panel 51C, the middle panel 52C, and the lower panel 53C are attached to the support 4C. When attaching the upper panel 51C to the support 4C, the pair of hook portions 51f of the upper panel 51C are hooked onto the upper end 11m of the first vertical frame 11 and the upper end 12m of the second vertical frame 12, and the upper panel 51C is attracted to the magnet 21 attached to the support 4C. When attaching the middle panel 52C to the support 4C, the hook portion 52f of the middle panel 52C is hooked onto the middle portion 14e of the middle horizontal frame 14C, and the middle panel 52C is attracted to the magnet 21 attached to the support 4C. When attaching the lower panel 53C to the support 4C, the hook portion 53f of the lower panel 53C is hooked onto the middle portion 15e of the middle horizontal frame 15C, and the lower panel 53C is attracted to the magnet 21 attached to the support 4C. This results in a panel set consisting of the upper panel 51C, middle panel 52C, and lower panel 53C being attached to the wall 1.

[Fifth embodiment]
Next, a fifth embodiment will be described. The fifth embodiment is basically the same as the fourth embodiment, and differs from the fourth embodiment only in that a protrusion is formed on the panel and that an insertion hole is formed in the support portion. Therefore, only the differences from the fourth embodiment will be described below, and the same matters as the fourth embodiment will be omitted.

The panel set of the wall structure according to the fifth embodiment includes an upper panel 51H, a middle panel 52H, and a lower panel 53H.

As shown in FIG. 38, the upper panel 51H is basically the same as the upper panel 51C of the fourth embodiment, and differs from the upper panel 51C of the fourth embodiment only in that a pair of protrusions 51h are fixed to the back surface 51d of the panel body 51a. The pair of protrusions 51h protrude from the back surface 51d below the pair of hooking portions 51f. More specifically, the pair of protrusions 51h are fixed at positions corresponding to the first vertical frame 11H and the second vertical frame 12H below the pair of hooking portions 51f, and extend in a rod-like shape horizontally from the back surface 51d. Note that "below" below the pair of hooking portions 51f means below in the vertical direction, and does not necessarily have to be at the same position in the horizontal direction. The pair of hooks 51f are the same as those in the fourth embodiment, but have a first hook 51f1 that protrudes from the back surface 51D and hooks vertically to the support 4H, and a second hook 51f2 that extends downward from the first hook 51f1 and hooks to the support 4H from the opposite side of the upper panel 51H. The first hook 51f1 extends horizontally from the back surface 51D, and is formed to a length such that the second hook 51f2 is positioned on the opposite side of the first vertical frame 11H and the second vertical frame 12H from the upper panel 51H.

As shown in FIG. 39, the middle panel 52H is basically the same as the middle panel 52C of the fourth embodiment, and differs from the middle panel 52C of the fourth embodiment only in that a pair of protrusions 52h are fixed to the back surface 51d of the panel body 51a. The pair of protrusions 52h protrude from the back surface 51d below the hooking portion 52f. More specifically, the pair of protrusions 52h are fixed at positions corresponding to the first vertical frame 11H and the second vertical frame 12H below the hooking portion 52f, and extend in a rod-like shape horizontally from the back surface 51d. Note that "below" below the hooking portion 52f means below in the vertical direction, and does not necessarily have to be at the same position in the horizontal direction. The pair of hooks 52f are the same as those in the fourth embodiment, but have a first hook 52f1 that protrudes from the back surface 51D and hooks vertically to the support 4H, and a second hook 52f2 that extends downward from the first hook 52f1 and hooks to the support 4H from the opposite side of the middle panel 52H. The first hook 52f1 extends horizontally from the back surface 51D, and is formed to a length such that the second hook 52f2 is positioned on the opposite side of the first vertical frame 11H and the second vertical frame 12H from the middle panel 52H.

The lower panel 53H is basically the same as the lower panel 53C of the fourth embodiment, and differs from the lower panel 53C of the fourth embodiment only in that a pair of protrusions 53h are fixed to the back surface 51d of the panel body 51a. The pair of protrusions 53h protrude from the back surface 51d below the hooking portion 53f. More specifically, the pair of protrusions 53h are fixed at positions corresponding to the first vertical frame 11H and the second vertical frame 12H below the hooking portion 53f, and extend in a rod-like shape horizontally from the back surface 51d. Note that "below" below the hooking portion 53f means below in the vertical direction, and does not necessarily have to be at the same position in the horizontal direction. The pair of hooks 53f are the same as those in the fourth embodiment, but have a first hook 53f1 that protrudes from the back surface 51D and hooks vertically to the support 4H, and a second hook 53f2 that extends downward from the first hook 53f1 and hooks to the support 4H from the opposite side of the lower panel 53H. The first hook 53f1 extends horizontally from the back surface 51D, and is formed to a length such that the second hook 53f2 is positioned on the opposite side of the lower panel 53H of the first vertical frame 11H and the second vertical frame 12H.

As shown in Fig. 37, the first vertical frame 11H and the second vertical frame 12H are basically the same as the first vertical frame 11 and the second vertical frame 12 of the fourth embodiment, but differ from the first vertical frame 11 and the second vertical frame 12 of the fourth embodiment only in that insertion holes are formed. The upper end 11m of the first vertical frame 11H and the upper end 12m of the second vertical frame 12H are hooked portions to which a pair of hooking portions 51f of the upper panel 51H are hooked in the vertical direction, the upper end 14h of the intermediate portion 14e of the middle horizontal frame 14C is hooked portions to which the hooking portion 52f of the middle panel 52H is hooked in the vertical direction, and the upper end 15h of the intermediate portion 15e of the middle horizontal frame 15H is hooked portions to which the hooking portion 53f of the lower panel 53H is hooked in the vertical direction. In the following description, the pair of hooking portions 51f of the upper panel 51H, the hooking portion 52f of the middle panel 52H, and the hooking portion 53f of the lower panel 53H are also referred to simply as "hooking portions", and the upper end 11m of the first vertical frame 11H and the upper end 12m of the second vertical frame 12H, the upper end 14h of the middle portion 14e of the middle horizontal frame 14C, and the upper end 15h of the middle portion 15e of the middle horizontal frame 15H are also referred to simply as "hooked portions".

The first vertical frame 11H and the second vertical frame 12H are formed with insertion holes 11r and 12r into which the pair of protrusions 51h of the upper panel 51H are inserted, insertion holes 11s and 12s into which the pair of protrusions 52h of the middle panel 52H are inserted, and insertion holes 11t and 12t into which the pair of protrusions 53h of the lower panel 53H are inserted. The insertion holes 11r and 12r are formed at positions corresponding to the pair of protrusions 51h of the upper panel 51H when the pair of first hooking portions 51f1 of the upper panel 51H are hooked to the upper end 11m of the first vertical frame 11H and the upper end 12m of the second vertical frame 12H. The insertion holes 11s and 12s are formed at positions corresponding to the pair of protrusions 52h of the middle panel 52H when the first hook portion 52f1 of the middle panel 52H is hooked to the upper end 14h of the intermediate portion 14e of the middle horizontal frame 14C. The insertion holes 11t and 12t are formed at positions corresponding to the pair of protrusions 53h of the lower panel 53H when the first hook portion 53f1 of the lower panel 53H is hooked to the upper end 15h of the intermediate portion 15e of the middle horizontal frame 15H. The shapes of the insertion holes 11r, 12r, 11s, 12s, 11t, and 12t are not particularly limited and may be, for example, a square, a circle, or the like. In FIG. 37, these insertion holes are shown as a rectangle (square) with a horizontal bottom side as an example.

As shown in FIG. 40, the vertical length of the second hook portion 51f2 is preferably longer than the length of the vertical gap above the protrusion 51h in the insertion hole 11r and the insertion hole 12r. To explain in detail, the vertical length of the second hook portion 51f2 is the hook portion length A1, the vertical length from the upper end 11m of the first vertical frame 11H and the upper end 12m of the second vertical frame 12H to the protrusion 51h is the length C1, the vertical length from the upper end 11m of the first vertical frame 11H and the upper end 12m of the second vertical frame 12H to the insertion hole 11r and the insertion hole 12r is the length D1, and the length obtained by subtracting the length D1 from the length C1 is the upper gap length B1. In this case, it is preferable that the hook portion length A1 is longer than the upper gap length B1.

As shown in FIG. 41, the vertical length of the second hook portion 52f2 is preferably longer than the length of the vertical gap above the protrusion 52h in the insertion hole 11s and the insertion hole 12s. To explain in detail, the vertical length of the second hook portion 52f2 is the hook portion length A2, the vertical length from the upper end 14h of the intermediate portion 14e of the middle horizontal frame 14C to the protrusion 52h is the length C2, the vertical length from the upper end 14h of the intermediate portion 14e of the middle horizontal frame 14C to the insertion hole 11s and the insertion hole 12s is the length D2, and the length obtained by subtracting the length D2 from the length C2 is the upper gap length B2. In this case, it is preferable that the hook portion length A2 is longer than the upper gap length B2.

The vertical length of the second hook portion 53f2 is preferably longer than the length of the vertical gap above the protrusion 53h in the insertion hole 11t and the insertion hole 12t. To explain in detail, the vertical length of the second hook portion 53f2 is the hook portion length A3, the vertical length from the upper end 15h of the intermediate portion 15e of the middle horizontal frame 15C to the protrusion 53h is C3, the vertical length from the upper end 15h of the intermediate portion 15e of the middle horizontal frame 15C to the insertion hole 11t and the insertion hole 12t is D3, and the length C3 minus length D3 is the upper gap length B3. In this case, it is preferable that the hook portion length A3 is longer than the upper gap length B3.

In the wall structure thus constructed, the upper horizontal frame 13 is fastened to the wall 1 by the fastening screws 17, the first vertical frame 11H and the second vertical frame 12H are connected to the upper horizontal frame 13 by the connecting screws 18, and the middle horizontal frame 14C, the middle horizontal frame 15C, and the lower horizontal frame 16 are connected to the first vertical frame 11H and the second vertical frame 12H to form the support body 4H. Therefore, the first vertical frame 11H and the second vertical frame 12H are indirectly fastened to the wall 1 via the upper horizontal frame 13, the fastening screws 17, and the connecting screws 18. The fastening positions of the vertical long holes 11f and the vertical long holes 12f relative to the connecting screws 18 are adjusted so that the first vertical frame 11H and the second vertical frame 12H are braced against the floor 2.

The upper panel 51H, middle panel 52H, and lower panel 53H are attached to the support 4H by magnets 21 (see FIG. 18). The upper panel 51H is attached to the support 4H by hooking a pair of hooking parts 51f onto the first vertical frame 11H and the second vertical frame 12H and by magnetic attraction of the magnet 21. The middle panel 52H is attached to the support 4H by hooking a hooking part 52f onto the middle horizontal frame 14C and by magnetic attraction of the magnet 21. The lower panel 53H is attached to the support 4H by hooking a hooking part 53f onto the middle horizontal frame 15C and by magnetic attraction of the magnet 21.

When constructing a wall structure configured in this manner, first, as in the first embodiment, the upper horizontal frame 13 is fastened to the wall 1, the first vertical frame 11H and the second vertical frame 12H are connected to the upper horizontal frame 13, and the middle horizontal frame 14C, middle horizontal frame 15C, and lower horizontal frame 16 are connected to the first vertical frame 11H and the second vertical frame 12H. Then, magnets 21 are attached to each of the first vertical frame 11H, the second vertical frame 12H, the upper horizontal frame 13, the middle horizontal frame 14C, the middle horizontal frame 15C, and the lower horizontal frame 16. This completes the construction of the support body 4H.

Next, as in the first embodiment, the upper panel 51H, middle panel 52H, and lower panel 53H are attached to the support 4H. When attaching the upper panel 51H to the support 4H, the pair of hook portions 51f of the upper panel 51H are hooked onto the upper end 11m of the first vertical frame 11H and the upper end 12m of the second vertical frame 12H, and the pair of protrusions 51h of the upper panel 51H are inserted into the insertion holes 11r of the first vertical frame 11H and the insertion holes 12r of the second vertical frame 12H. Then, the upper panel 51C is attracted to the magnet 21 attached to the support 4C. When the middle panel 52H is attached to the support 4H, the hook portion 52f of the middle panel 52H is hooked to the middle portion 14e of the middle horizontal frame 14C, and the pair of protrusions 52h of the middle panel 52H are inserted into the insertion hole 11s of the first vertical frame 11H and the insertion hole 12s of the second vertical frame 12H. Then, the middle panel 52H is attracted to the magnet 21 attached to the support 4H. When the lower panel 53H is attached to the support 4H, the hook portion 53f of the lower panel 53H is hooked to the middle portion 15e of the middle horizontal frame 15C, and the pair of protrusions 53h of the lower panel 53H are inserted into the insertion hole 11t of the first vertical frame 11H and the insertion hole 12t of the second vertical frame 12H. Then, the lower panel 53H is attracted to the magnet 21 attached to the support 4H. This results in a panel set consisting of the upper panel 51H, middle panel 52H, and lower panel 53H being attached to the wall 1.

In addition, the upper panel 51H, the middle panel 52H, and the lower panel 53H may be attracted to the support 4H by the magnetic force of the magnet 21 even if they are not hooked to the support 4H. Therefore, the magnet 21 may have a magnetic force such that the upper panel 51H is not attracted to the support 4H by the magnetic force of the magnet 21 when the pair of protrusions 51h of the upper panel 51H are not inserted into the insertion holes 11r and 12r and are abutted against the surfaces of the first vertical frame 11H and the second vertical frame 12H. In addition, the magnet 21 may have a magnetic force such that the middle panel 52H is not attracted to the support 4H by the magnetic force of the magnet 21 when the pair of protrusions 52h of the middle panel 52H are not inserted into the insertion holes 11s and 12s and are abutted against the surfaces of the first vertical frame 11H and the second vertical frame 12H. In addition, the magnet 21 may have a magnetic force such that when the pair of protrusions 53h of the lower panel 53H are not inserted into the insertion holes 11t and 12t and are in contact with the surfaces of the first vertical frame 11H and the second vertical frame 12H, the lower panel 53H is not attracted to the support 4H by the magnetic force of the magnet 21.

In this manner, in this embodiment, the pair of hook portions 51f of the upper panel 51H, the hook portion 52f of the middle panel 52H, and the hook portion 53f of the lower panel 53H can be hooked to the upper end 11m of the first vertical frame 11H and the upper end 12m of the second vertical frame 12H, the upper end 14h of the middle portion 14e of the middle horizontal frame 14C, and the upper end 15h of the middle portion 15e of the middle horizontal frame 15H, thereby allowing the upper panel 51H, the middle panel 52H, and the lower panel 53H to be installed on the support 4H.

Here, if an upward force acts on the upper panel 51H due to a worker bumping into it, the upper panel 51H may bounce up, and the pair of hooking portions 51f of the upper panel 51H, which are the hooking portions, may come off from the upper end 11m of the first vertical frame 11H and the upper end 12m of the second vertical frame 12H, which are the hooked portions. However, since the pair of protrusions 51h of the upper panel 51H are inserted into the insertion holes 11r and 12r of the support body 4H, even if an upward force acts on the upper panel 51H due to a worker bumping into it, the upward movement of the upper panel 51H is restricted. This prevents the upper panel 51H from bouncing up, and therefore prevents the pair of hooking portions 51f of the upper panel 51H, which are the hooking portions, from coming off from the upper end 11m of the first vertical frame 11H and the upper end 12m of the second vertical frame 12H, which are the hooked portions. The same applies to the middle panel 52H and the lower panel 53H.

In addition, when the pair of hooks 51f of the upper panel 51H are hooked to the upper end 11m of the first vertical frame 11H and the upper end 12m of the second vertical frame 12H, the first hook 51f1 is placed on the upper end 11m of the first vertical frame 11H and the upper end 12m of the second vertical frame 12H, and the second hook 51f22 is hooked to the support 4H from the opposite side of the upper panel 51H. As shown in FIG. 42, the vertical length of the second hook 51f2 is longer than the length of the vertical gap above the pair of protrusions 51h in the insertion holes 11r and 12r, so that even if an upward force acts on the upper panel 51H due to a worker bumping into it, the pair of hooks 51f can be prevented from coming off the upper end 11m of the first vertical frame 11H and the upper end 12m of the second vertical frame 12H. In other words, while the upper panel 51H can only move upward by the upper gap length B1, the hooking portion length A1 is longer than the upper gap length B1, so even if an upward force acts on the upper panel 51H due to a worker bumping into it, the pair of hooking portions 51f of the upper panel 51H can be prevented from coming off the upper end 11m of the first vertical frame 11H and the upper end 12m of the second vertical frame 12H. This is also true for the middle panel 52H and the lower panel 53H, as shown in FIG. 43.

The above describes a preferred embodiment of the present invention, but the present invention is not limited to the above embodiment and can be modified as appropriate.

For example, in the above embodiment, the horizontal cross section of each of the first vertical frame and the second vertical frame has been described as being U-shaped, but, for example, as in the wall structure support 4D shown in FIG. 32, recesses may be formed in the first vertical frame 11D and the second vertical frame, and the connection screws 18 may be screwed into the wall 1 from the recesses. This can improve the workability of fastening the connection screws 18 while preventing the connection screws 18 from protruding from the first vertical frame 11D and the second vertical frame.

In the above embodiment, the first vertical frame and the second vertical frame are described as being indirectly fastened to the wall via the upper horizontal frame, but for example, as in the wall structure support 4E shown in FIG. 33, the first vertical frame 11E and the second vertical frame 12E may be directly fastened to the wall 1 by the fastening screw 17. In this case, a vertically long hole is formed in the upper part of the first vertical frame 11E and the second vertical frame 12E, into which the fastening screw 17 is inserted. This allows the first vertical frame 11E and the second vertical frame 12E to be fastened to the wall 1, and allows the first vertical frame 11E and the second vertical frame 12E to be braced against the floor 2. In addition, instead of the upper horizontal frame 13, an upper horizontal frame 13E having the same shape as the lower horizontal frame 16 may be used.

In the above embodiment, the first and second vertical frames are braced against the floor by forming vertical long holes in the first and second vertical frames. However, for example, as in the wall structure support 4F shown in FIG. 34, extendable support legs 11n and 12n may be attached to the lower ends of the first and second vertical frames 11F and 12F. In this case, after connecting the first and second vertical frames 11F and 12F to the upper horizontal frame 13, the first and second vertical frames 11F and 12F can be braced against the floor 2 by extending the support legs 11n and 12n. Also, instead of the upper horizontal frame 13, an upper horizontal frame 13F having the same shape as the lower horizontal frame 16 may be used.

In the above embodiment, the lower ends of the first vertical frame and the second vertical frame are described as having notches formed therein corresponding to the baseboard 3, but if there is no baseboard as shown in FIG. 34, or if the baseboard does not pose a problem when installing the first vertical frame and the second vertical frame, it is not necessary to form such notches.

In the above embodiment, the first vertical frame and the second vertical frame are described as being directly supported against the floor, but they may be indirectly supported against the floor via other members such as baseboards.

In the above embodiment, the first vertical frame and the second vertical frame are used as the vertical frame, but it may be composed of only one vertical frame 11G, for example, as in the wall structure support 4G shown in FIG. 35. In the support 4G shown in FIG. 35, a vertical long hole 11p is formed in the upper part of the vertical frame 11G, into which the fastening screw 17 is inserted. Therefore, the vertical frame 11G can be fastened to the wall 1 by screwing the fastening screw 17 into the wall 1 through the vertical long hole 11p, and the vertical frame 11G can be braced against the floor 2 by adjusting the fastening position of the fastening screw 17 relative to the vertical long hole 11p. The panel 5 can be attached to the vertical frame 11G by, for example, magnetic attraction or adhesion.

In addition, in the above embodiment, multiple panels are attached to the support, but, for example, only one panel may be attached to the support.

In the above embodiment, all or part of the frame may be made of a ferromagnetic material or magnets that are attracted by magnetic force, but only the vertical frame or only part of the vertical frame may be made of magnets. This allows the panel to be stably fixed at low cost, and also makes it easier to adjust the fixing position of the panel.

In the above embodiment, the horizontal and vertical frames are described as having slits into which flat plate-shaped hooks are inserted as cutouts for hanging the panels, but instead of slits, they may have large openings into which hook-shaped hooks are inserted.

In the above embodiment, the upper horizontal frame is described as having no cutouts such as slits, but the upper horizontal frame may have cutouts such as slits formed in the middle horizontal frame. This allows the panel to be hung on the upper horizontal frame as well.

In the above embodiment, the horizontal frame is described as having a screw hole for connection and the vertical frame is described as having a vertical long hole, but the vertical frame may be described as having a screw hole for connection and the horizontal frame is described as having a vertical long hole.

In addition, in the above embodiment, the multiple screw holes 7 are described as being arranged in a horizontal row at equal intervals at a predetermined height position on the upper part of the wall 1, but the multiple screw holes 7 do not have to be arranged at equal intervals, and may be arranged with a certain regularity or periodicity other than equal intervals.

In the above embodiment, the vertical frame is fastened to the wall by screwing the fastening screws into the screw holes formed in the wall. However, if there are no screw holes in the wall or if there are no screw holes in the desired fastening position, the vertical frame may be fastened to the wall by screwing the fastening screws into the wall itself.

In the above embodiment, the panel body of the panel is described as being formed in a box shape with the entire surface covered, but it may be formed in a shape with the back surface 5d side open, as in the panel 5A shown in FIG. 36. The panel 5A shown in FIG. 36 includes a panel body 5a and a hook portion 5b fixed to the back surface 5d of the panel body 5a for hooking the panel 5A to the support. The panel body 5a is formed in a shape with the back surface 5d side and the top and bottom surfaces open by folding both ends of a single steel plate from the front surface 5c side to the back surface 5d side. The panel body 5a may be formed in a shape with only the back surface 5d side open by folding all four sides of a single steel plate from the front surface 5c side to the back surface 5d side.

In addition, in the above embodiment, the panel is attached to the support by magnet attraction, but the panel may be attached to the support without a magnet (without magnet attraction).
