Description

The present invention relates to a structure and method for installing a frame on two sides of an opening formed in an interior wall that extends from the floor to the ceiling.

In recent years, in buildings such as houses, fittings (so-called high doors) that open and close openings that reach from the floor to the ceiling without having a drop wall at the opening have been widely used. In order to give this type of fitting a good appearance, some fittings are constructed so that the upper frame of the three-sided frame is embedded in the ceiling, making it look as if two-sided frames have been installed (for example, see Patent Document 1 below).

In the fitting device disclosed in Patent Document 1, a three-sided frame is assembled and fixed inside the opening before the ceiling material is installed, and then the ceiling material is installed so that the underside of the ceiling material is flush with the underside of the upper frame. In the fitting device disclosed in Patent Document 1, the three-sided frame is installed in this way so that the upper frame is embedded in the ceiling, making it appear as if a two-sided frame without an upper frame has been installed.

JP 2019-11559 A

However, while the above-mentioned fixture device configuration can create the appearance of a neat two-sided frame without an upper frame, it is not easy to fix the ceiling material while adjusting its position so that the undersides of the ceiling material and the upper frame are flush, and it is also necessary to install separate parts for adjusting the position, which makes the installation work complicated.

The present invention was made in consideration of these points, and its purpose is to make it easier to install two-sided frames in openings that extend from the floor to the ceiling.

To achieve the above objective, the present invention provides a construction structure in which a pair of vertical frames that form two sides of the frame are removably connected to connecting members that vertically connect at least the upper ends of the frames.

Specifically, the first invention is a two-sided frame construction structure for constructing two-sided frames in an opening formed in an interior wall that extends from the floor to the ceiling, and is characterized in that it comprises a pair of vertical frames that form the two-sided frames, and a connecting member that vertically connects at least the upper ends of the pair of vertical frames, and that the connecting member is removably fixed to each of the vertical frames.

In the first invention, in order to construct a good-looking two-sided frame without an upper frame, a construction structure is used in which a connecting member that connects at least the upper end vertically is removably fixed to a pair of vertical frames that make up the two-sided frame. With this construction structure, the construction structure is fitted into an opening formed in an interior wall that extends from the floor to the ceiling, and after the pair of vertical frames are fixed, the connecting member is simply removed, and a good-looking two-sided frame without an upper frame can be easily constructed in the opening without complex alignment.

The second invention is the first invention, characterized in that a groove for providing a door stop is formed on the opposing inner surfaces of the pair of vertical frames, and the connecting member extends from within the groove of one of the pair of vertical frames to within the groove of the other vertical frame, and is removably fixed to each of the vertical frames.

In the second invention, the connecting member is removably fitted across the grooves that provide the doorstops of a pair of vertical frames. With this configuration, even if a nail-shaped member such as a screw is used to fasten the connecting member, the hole made by the nail-shaped member is hidden by the doorstop and cannot be seen after the connecting member is removed. Therefore, according to the second invention, a good-looking two-sided frame without a top frame can be easily installed in the opening without compromising the design.

The third invention is the second invention, characterized in that the connecting member is removably fixed to each of the vertical frames by a nail-shaped member that is driven from the space side between the pair of vertical frames toward the inner surface of the groove so as to penetrate the connecting member.

The construction structure is fixed in the opening by being fixed to the pillars installed on both sides of the opening. Therefore, if the connecting members are fixed to each vertical frame by driving nail-shaped members from the outside of a pair of vertical frames toward the ends of the connecting members, the nail-shaped members cannot be pulled out after the construction structure is installed in the opening.

Therefore, in the third invention, the nail-shaped members that secure the connecting members to the vertical frames are driven from the space between the pair of vertical frames toward the inner surface of the door-stop groove into which the end of the connecting member fits, penetrating the connecting members. By driving the nail-shaped members in this direction, it becomes possible to pull out the nail-shaped members after the construction structure is secured in the opening, and it becomes possible to remove the connecting members.

The fourth invention is the second invention, characterized in that the connecting member is arranged to connect the upper and lower ends of the pair of vertical frames.

In the fourth invention, the upper and lower ends of a pair of vertical frames are connected by two connecting members, respectively, making it possible to easily and visually install the pair of vertical frames in an opening while maintaining a parallel positional relationship.

The fifth invention is a method for constructing a two-sided frame in an opening extending from the floor to the ceiling formed between two pillars in a wall inside a room, characterized in that it includes a fixing step of placing the construction structure according to the first invention at a predetermined construction position in the opening and fixing the pair of vertical frames to the two pillars installed on both sides of the opening, and a removal step of removing the connecting member from the construction structure fixed to the two pillars.

The sixth invention is a method for constructing a two-sided frame in an opening formed between two pillars of an interior wall and extending from the floor to the ceiling, and is characterized by comprising a fixing step of placing a construction structure according to any one of the second to fourth inventions at a predetermined construction position within the opening and fixing the pair of vertical frames to the two pillars installed on both sides of the opening, a removal step of removing the connecting member from the construction structure fixed to the two pillars, and a door stop construction step of providing the door stop in each of the grooves of the pair of vertical frames.

In the fifth and sixth inventions, the above-mentioned construction structure is used to construct the two-sided frame, and the construction structure is placed in a predetermined construction position within the opening, and the pair of vertical frames are fixed to two pillars installed on both sides of the opening. After that, the connecting members are removed from the construction structure, so that only the pair of vertical frames that will become the two-sided frame are constructed within the opening. With this construction method, a good-looking two-sided frame without an upper frame can be easily constructed within the opening without the need for complicated positioning as in the past.

In addition, in the sixth invention, after the connecting member is removed, a door stop is provided in the groove of the pair of vertical frames through which the connecting member was spanned. Therefore, even if a nail-shaped member such as a screw is used to fasten the connecting member, the hole made by the nail-shaped member will be hidden by the door stop and will not be visible after the connecting member is removed. Therefore, according to the sixth invention, a good-looking two-sided frame without a top frame can be easily installed in the opening without compromising the design.

As explained above, according to the present invention, a construction structure is constructed in which a pair of vertical frames that form two sides are removably connected to connecting members that vertically connect at least the upper ends of the frames, making it easier than ever to construct a good-looking two-sided frame without an upper frame in an opening that extends from the floor to the ceiling.

First Embodiment of the Invention
Fig. 1 is a front view of a fitting device 1 equipped with a two-sided jamb 10 and a door (fitting) 50 constructed by the two-sided jamb construction method according to the present invention in a rectangular opening O formed in a wall W of a room, Fig. 2 is a cross-sectional view of the fitting device 1, and Fig. 3 is a vertical cross-sectional view of the fitting device 1. For ease of explanation, the left side, right side, upper side, and lower side of Fig. 1 will be referred to as "left", "right", "upper", and "lower", respectively. Also, the near side in the direction perpendicular to the paper surface of Fig. 1 will be referred to as "front" and the far side as "rear".

As shown in Figures 1 to 3, the wall W is a large-wall structure wall, and is constructed by fixing multiple wall underlayment materials 3, 3 to both the front and rear sides of the pillars (including partitions) 2, 2. The ceiling C is a suspended ceiling, and is constructed by fixing multiple sidings 6, 6 to the lower ends of multiple siding supports 5, 5 fixed to multiple hanging beams (not shown) so that they are perpendicular to the multiple siding supports 5, 5, and further fixing multiple ceiling materials (such as gypsum boards) 7, 7 to the lower ends of the multiple sidings 6, 6. The opening O is formed between the two pillars 2, 2 in the wall W. The upper end of the opening O is defined by the ceiling surface Cs (the lower surface of the ceiling finishing material such as wallpaper), which is the decorative surface of the ceiling C, and the lower end of the opening O is defined by the floor surface Fs, which is the decorative surface of the floor F. In other words, the opening O is formed so as to reach the ceiling surface Cs.

In this embodiment 1, the fitting device 1 comprises a two-sided frame 10 that is installed in an opening O of a wall W, and a door 50. The door 50 is attached to the two-sided frame 10 by upper and lower hinges 51, 51 so as to be able to swing, and is equipped with a lever 52 for opening and closing. The present invention is characterized by a construction structure A and construction method for easily constructing the two-sided frame 10. The two-sided frame 10, construction structure A, and construction method will be described in detail below in that order.

-Detailed structure of the two-sided frame-
The door frame 10 is a two-sided frame with a pair of vertical frames 11, 11, with no upper or lower frame. The door frame 10 is attached to the left and right ends of the wall W that defines the opening O. In this embodiment 1, the door frame 10 is attached to the inner surface (the surface on the opening O side) of two pillars 2, 2 in the wall W that defines the opening O via a spacer 4. The spacer 4 is made of a long wooden board material with a thickness of 10 to 20 mm and a width equal to or less than the thickness of the wall W. The door frame 10 is attached to the left and right ends of the wall W including the spacer 4. In this embodiment 1, a pair of trim members 12, 12 and a door stop 13 are attached to each vertical frame 11.

2 and 3, a pair of vertical frames 11, 11 have the same cross-sectional structure and are arranged symmetrically. The vertical frame 11 is a long wooden board member extending in the vertical direction and made of wood materials such as wood, plywood, medium density fiberboard, particle board, and laminated wood, and has an H-shaped cross section. The vertical frame 11 has a front-to-back width (projected dimension) shorter than the thickness of the wall W, a thickness (visible dimension) of 18 to 30 mm, and a vertical length the same as the vertical length of the opening O (the distance between the floor surface Fs and the ceiling surface Cs). The vertical frame 11 is arranged in the opening O so that its outer surface abuts against the end face of the end of the wall W (in this embodiment, the inner surface of the spacer 4), and is fixed to the pillar 2 via the spacer 4 by adhesive and nail-shaped members 41 such as nails, pin nails, and screws. The vertical frame 11 may be made of resin or steel.

A groove 15 is formed on the front and rear surfaces of the vertical frame 11, extending vertically in the middle in the left-right direction (viewing direction). The groove 15 is formed so as to extend from the upper end to the lower end of the vertical frame 11. The ends of a pair of trim pieces 12, 12 are inserted into the groove 15.

A groove 16 is formed on the inner surface of the vertical frame 11 (the surface where the pair of vertical frames 11, 11 face each other) in the middle of the front-to-rear direction (projection direction) and extends vertically. The groove 16 is formed so as to extend from the upper end to the lower end of the vertical frame 11. The support leg 13b of the door stop 13 is inserted into the groove 16.

The trim 12 is a long wooden board member extending in the vertical direction, made of wood materials such as wood, plywood, medium density fiberboard, particle board, laminated wood, etc., and its vertical length is the same as that of the vertical frame 11. The trim 12 has a vertical board portion 12a extending in the projection direction and a horizontal board portion 12b extending in the projection direction from the end of the vertical board portion 12a, and is formed with an L-shaped cross section. The end of the vertical board portion 12a of the trim 12 is inserted into a groove 15 formed on the front and rear surfaces of the vertical frame 11, and the end of the horizontal board portion 12b is positioned and fixed in a position where it abuts against the end of the wall W. The trim 12 covers and hides the joint between the vertical frame 11 and the end of the wall W. The trim 12 may be made of wood, resin, or steel.

The door stop 13 is a long member extending in the vertical direction, made of a resin material such as ABS (Acrylonitrile Butadiene Styrene) resin, and its vertical length is formed to be the same as that of the vertical frame 11. The door stop 13 has a main body portion 13a and a support leg portion 13b. The main body portion 13a has a U-shaped cross section. The support leg portion 13b consists of two support legs that protrude outward from the two ends of the main body portion 13a. The two support legs are made of plate-shaped pieces that extend in the vertical direction and the front direction (left and right direction), and face each other in the front direction (front and back direction). The outer ends of the two support legs are formed with engagement protrusions that engage with the inner surface of the groove 16 of the vertical frame 11. The door stop 13 is fixed to the vertical frame 11 with an adhesive or the like, with the support leg portion 13b inserted into the groove 16 formed on the inner surface of the vertical frame 11.

The details will be described later, but in this embodiment 1, in addition to its role as a normal door stop, the door stop 13 also serves to hide the screw holes (nail holes) of the screws (nail-shaped members) 31 that secure the connecting members 14 of the construction structure A, which will be described later.

- Two-sided frame construction structure -
In the first embodiment, the construction of the two-sided frame 10 is facilitated by constructing the two-sided frame 10 using the construction structural body A shown in FIGS.

The construction structure A includes a pair of vertical frames 11, 11 that form two side frames 10, and a connecting member 14 that connects the pair of vertical frames 11, 11 vertically in a parallel state.

In the first embodiment, the connecting member 14 is composed of a strip-shaped member extending in the left-right direction. The connecting member 14 is formed so that the thickness in the front-rear direction is slightly thinner than the width in the front-rear direction of the groove 16 so that the left and right ends of the connecting member 14 fit into the groove 16 for providing the door stop 13 formed on the inner surface of the vertical frame 11. The length in the front-rear direction (left-right direction) of the connecting member 14 is formed to a length that connects the pair of vertical frames 11, 11 at the desired installation interval (a designed interval that allows the pair of vertical frames 11, 11 to be installed in the opening O) when the left and right ends of the connecting member 14 are inserted until they abut against the groove bottoms in the grooves 16, 16 of the pair of vertical frames 11, 11 and fixed to each vertical frame 11.

In the first embodiment, the pair of vertical frames 11, 11 are connected by two connecting members 14, 14. One of the two connecting members 14, 14 is provided so as to span between the upper ends of the pair of vertical frames 11, 11, connecting the upper ends. The other of the two connecting members 14, 14 is provided so as to span between the lower ends of the pair of vertical frames 11, 11, connecting the lower ends.

In addition, in the first embodiment, each connecting member 14 extends from the groove 16 for providing the door stop 13 of one of the pair of vertical frames 11, 11 to the groove 16 for providing the door stop 13 of the other vertical frame 11, and is removably fixed to each vertical frame 11. By fixing each connecting member 14 to each vertical frame 11 with the left and right end faces of each connecting member 14 abutting against the bottom faces of the grooves 16, 16 of the pair of vertical frames 11, 11, the pair of vertical frames 11, 11 are connected with the desired installation interval described above.

In the first embodiment, the connecting members 14 are removably fixed to each vertical frame 11 with screws (nail-shaped members) 31.

Specifically, as shown in Figs. 4 and 6, the connecting member 14 is fixed to each vertical frame 11 by driving the screws 31 from the space S side sandwiched between the pair of vertical frames 11, 11 toward the inner surface of the groove 16 so as to penetrate the left and right ends of the connecting member 14. In this way, the screws 31 are driven from the space S side sandwiched between the pair of vertical frames 11, 11 toward the inner surface of the groove 16, rather than being driven toward the connecting member 14 from the outside of the pair of vertical frames 11, 11, so that the screws 31 can be removed after the construction structure A is placed in the opening O and the pair of vertical frames 11, 11 are fixed to the columns 2, 2. The connecting member 14 can be removed from the pair of vertical frames 11, 11 by pulling out the screws 31, cutting, etc. In the first embodiment, the left and right ends of the connecting member 14 are fixed to the pair of vertical frames 11, 11 with the screws 31 as described above, so that the connecting member 14 is removably fixed to each vertical frame 11.

-How to install two-sided frames-
Next, a description will be given of a method for constructing the two-sided frame 10. As described above, in the first embodiment, the two-sided frame 10 is constructed using the construction structure A in which a pair of vertical frames 11, 11 are connected by the connecting member 14.

First, the construction structure A is assembled (assembly process). Specifically, as shown in FIG. 4, the left and right ends of the connecting member 14 are inserted into the grooves 16, 16 for providing the door stop 13 of a pair of vertical frames 11, 11 until the end faces abut the bottom of the groove, and screws 31 are driven from the space S side between the pair of vertical frames 11, 11 toward the inner surface of the groove 16 so as to penetrate the left and right ends of the connecting member 14, thereby removably fixing the connecting member 14 to each vertical frame 11.

After the assembly process, as shown in FIG. 7A, the assembled construction structure A is placed at a predetermined construction position in the opening O, and a pair of vertical frames 11, 11 of the construction structure A are fixed to the pillars 2, 2 installed on both sides of the opening O. Specifically, a spacer 4 is inserted between each vertical frame 11 and each pillar 2, and a screw 41 is driven from the inner side of each vertical frame 11 toward the pillar 2, thereby fixing each vertical frame 11 to the corresponding pillar 2 via the spacer 4.

After the fixing process, as shown in FIG. 7B, the connecting member 14 is removed from the construction structure A fixed to the pillars 2, 2 installed on both sides of the opening O (removal process). Specifically, the screws 31, 31 that were driven into the left and right ends of the connecting member 14 are pulled out and the connecting member 14 is removed from the pair of vertical frames 11, 11. In the first embodiment, after the screws 31, 31 are pulled out, the connecting member 14 is cut and removed.

After the removal process, as shown in FIG. 7C, the door stop 13 is attached to the pair of vertical frames 11, 11 (door stop installation process). Specifically, adhesive is applied to the grooves 16, 16 of the pair of vertical frames 11, 11, and the narrow portion 13b of the door stop 13 is inserted and fixed.

Through the above steps, the two-sided frame 10 is installed inside the opening O.

The trim material 12 is attached to the pair of vertical frames 11, 11 after the wall base materials 3, ..., 3 are installed. The trim material 12 is fixed to the vertical frames 11 with nail-shaped members such as pin nails after the ends of the vertical plate portions 12a are inserted into the grooves 15 formed on the front and rear surfaces of the vertical frames 11 and the ends of the horizontal plate portions 12b are positioned to abut the ends of the wall W (the ends of the wall base materials 3).

--Effects of the First Embodiment--
In this embodiment 1, in order to construct a good-looking two-sided frame 10 without an upper frame, a construction structural body A is used in which a connecting member 14 that connects at least the upper end portions vertically is removably fixed to a pair of vertical frames 11, 11 that constitute the two-sided frame 10. With such a construction structural body A, the construction structural body A is fitted into an opening O formed in a wall W of a room, which extends from a floor surface Fs to a ceiling surface Cs, and after the pair of vertical frames 11, 11 are fixed, the connecting member 14 is simply removed, and the good-looking two-sided frame 10 without an upper frame can be easily constructed in the opening O without complex alignment.

In addition, in this embodiment 1, the connecting member 14 is removably fitted across the groove 16 in which the door stop 13 of the pair of vertical frames 11, 11 is provided. With this configuration, even if a screw (nail-shaped member) 31 is used to fasten the connecting member 14, after the connecting member 14 is removed, the hole made by the screw (nail-shaped member) 31 is hidden by the door stop 13 and cannot be seen. Therefore, according to this embodiment 1, a good-looking two-sided frame 10 without an upper frame can be easily installed in the opening O without compromising the design.

The construction structure A is fixed in the opening O by being fixed to the pillars 2, 2 installed on both sides of the opening O. Therefore, if the connecting member 14 is fixed to each vertical frame 11 by driving a screw (nail-shaped member) 31 from the outside of the pair of vertical frames 11, 11 toward the end of the connecting member 14, the screw (nail-shaped member) 31 cannot be pulled out after the construction structure A is installed in the opening O.

Therefore, in this embodiment 1, the screws (nail-shaped members) 31 that secure the connecting members 14 to each vertical frame 11 are driven from the space S between the pair of vertical frames 11, 11 toward the inner surface of the door stop groove 16 into which the end of the connecting member 14 fits, penetrating the connecting members 14. By driving the screws (nail-shaped members) 31 in this direction, it becomes possible to pull out the screws (nail-shaped members) 31 after the construction structure A is secured within the opening O, and it becomes possible to remove the connecting members 14.

In addition, in this embodiment 1, the upper and lower ends of a pair of vertical frames 11, 11 are connected by two connecting members 14, 14, respectively, so that the pair of vertical frames 11, 11 can be easily and visually installed in the opening O while maintaining a parallel positional relationship.

In addition, in the construction method of the first embodiment, a construction structure A is used to construct the two-sided frame 10, and the construction structure A is placed at a predetermined construction position in the opening O, and the pair of vertical frames 11, 11 are fixed to the pillars 2, 2 installed on both sides of the opening O. Then, the connecting member 14 is removed from the construction structure A, so that only the pair of vertical frames 11, 11 that will become the two-sided frame 10 are constructed in the opening O. With this construction method, a good-looking two-sided frame 10 without an upper frame can be easily constructed in the opening O without the need for complicated positioning as in the conventional method.

In addition, in the construction method of this embodiment 1, after removing the connecting member 14, the door stop 13 is provided in the grooves 16, 16 of the pair of vertical frames 11, 11 across which the connecting member 14 was spanning. Therefore, even if a screw (nail-shaped member) 31 is used to fasten the connecting member 14, the hole made by the screw (nail-shaped member) 31 is hidden by the door stop 13 and cannot be seen after removing the connecting member 14. Therefore, according to the construction method of this embodiment 1, a good-looking two-sided frame 10 without an upper frame can be easily constructed in the opening O without compromising the design.

Other Embodiments
In the above-mentioned first embodiment, in the construction structure A, the pair of vertical frames 11, 11 are connected by two connecting members 14, 14, but the number of connecting members 14 is not limited to this. The number of connecting members 14 may be one or three or more as long as at least the upper ends of the pair of vertical frames 11, 11 are connected by the connecting members 14.

In addition, in the above embodiment 1, the connecting member 14 is configured as a strip-shaped member, but it may be configured as a non-elongated rectangular plate-shaped member whose left and right ends are inserted and fixed into the grooves 16, 16 of the pair of vertical frames 11, 11.

In addition, in the above embodiment 1, in the construction structure A, the connecting members 14 are removably fixed to each vertical frame 11 using screws 31 (nail-like members), but the means for removably fixing the connecting members 14 to each vertical frame 11 is not limited to screws 31, and they may be fixed using nail-like members other than screws 31, such as nails or pin nails.

Furthermore, the means for removably fixing the connecting member 14 to each vertical frame 11 may be other than nail-shaped members. For example, dowel grooves may be formed on the underside of the left and right ends of the connecting member 14, and the connecting member 14 may be removably fixed to each vertical frame 11 using dowels. Also, the connecting member 14 may be removably fixed to each vertical frame 11 using knockdown metal fittings or the like, in which the connecting member 14 side and the vertical frame 11 side engage with each other when the screw in the connecting member 14 side engaging member is tightened after the connecting member 14 side engaging member is inserted until it abuts the bottom surface of the grooves 16, 16 of the pair of vertical frames 11, 11. When using dowels or knockdown metal fittings, it is preferable to embed the dowels or engaging members in the grooves 16, 16 of the vertical frames 11. This is because the dowel holes and the embedding holes of the engaging members can be hidden by the door stop 13 simply by providing the door stop 13 after removing the connecting member 14.

In addition, in the above embodiment 1, the connecting member 14 is provided so as to span between the bottom surfaces of the grooves 16 of the pair of vertical frames 11, 11, but the connecting member 14 may also be spanned between parts of the inner surfaces of the pair of vertical frames 11, 11 other than the grooves 16, 16, and removably fixed to each vertical frame 11.

In the above embodiment 1, one groove 16 is formed on the inner surface of each vertical frame 11 for one door stop 13, into which the two support legs constituting the support leg portion 13b are inserted, but two grooves 16 may be formed and the two support legs may be inserted separately. In this case, for example, the connecting member 14 may be removably fixed to each vertical frame 11 by driving a screw 31 (nail-shaped member) from the space S between the pair of vertical frames 11, 11 into the two grooves 16, 16 and between the two grooves 16, 16 so as to penetrate the connecting member 14 while the left and right ends of the connecting member 14 are in contact with the two grooves 16, 16 on the inner surface of each vertical frame 11.

In the above embodiment 1, the door stop 13 is configured to have a main body 13a and a support leg 13b, but the door stop 13 may have any configuration as long as it can fulfill the role of a door stop and the role of hiding the screw hole (nail hole) of the screw (nail-shaped member) 31 as described above. For example, the door stop 13 may not have two support legs, but may have a wide portion with a long width (length in the prospective direction) and a narrow portion with a short width, be composed of a hollow member extending in the vertical direction with a convex cross section, and be fixed to the vertical frame 11 with an adhesive or the like while the narrow portion is inserted into the groove 16.

The shape of the vertical frame 11 is not limited to that of the first embodiment, and may be any shape. The vertical frame 11 may not have a groove 15 and may not have trim materials 12, 12.

Furthermore, the door stop 13 and the groove 16 are not limited to the shape of embodiment 1 and may have any shape.

This invention is useful for installing two-sided frames in openings formed in interior walls that extend from the floor to the ceiling.
