FIG.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
In some drawings, some of the detailed reference numerals used in other drawings are omitted.
In the following embodiment, directions such as up and down directions will be described based on the state in which the partition wall device according to this embodiment is installed.

1 to 8 are diagrams that diagrammatically show an example of a partition wall device, a partition wall construction method, and a partition wall structure according to this embodiment.
As shown in Figure 1, the partition wall device 1 of this embodiment comprises a pair of pillars 20, 20 whose lower ends are fixed to the floor 2, and a plurality of partition panels 10, 10 arranged between the pair of pillars 20, 20.
The building to which this partition wall device 1 is applied is not limited to a residential building such as a detached house or an apartment building, but may be a commercial facility, a public facility, etc. Furthermore, this partition wall device 1 can be installed in various locations.
Furthermore, the floor 2 on which the lower end of this partition wall device 1 is to be installed may be a floor substructure or a floor finishing material fixed to the floor substructure.

This partition wall device 1 includes a column-shaped connecting member 17 that connects adjacent partition panels 10, 10, and a floor-side frame 31 that extends between a pair of supports 20, 20 and holds the lower end protrusions 15 that constitute the lower end of the partition panel 10. The partition wall device 1 also includes an upper frame 41 that extends between a pair of supports 20, 20, has each longitudinal end fixed to each of the pair of supports 20, 20, and holds the upper end protrusions 14 that constitute the upper end of the partition panel 10, 10. With this configuration, the lower end protrusions 15 of the multiple partition panels 10, 10 can be held by the floor-side frame 31, and the adjacent partition panels 10, 10 can be connected by the column-shaped connecting member 17, and a partition wall can be easily constructed using these multiple partition panels 10, 10. In addition, since the columnar connecting members 17 are provided between the adjacent partition panels 10, 10, the gap between the adjacent partition panels 10, 10 can be shielded by the columnar connecting members 17. In addition, by fixing each longitudinal end of the upper frame 41 to a pair of supports 20, 20, the multiple partition panels 10, 10 can be stably held by the pair of supports 20, 20, the floor side frame 31, and the upper frame 41. In addition, since there is no need to fix the upper frame 41 to the ceiling surface 3 or ceiling substrate, the partition wall device 1 can be installed without being affected by the ceiling side structure.

As shown in Fig. 3(b) and Fig. 4(a), the partition wall device 1 is provided with an unevenness adjustment member 35 for adjusting unevenness on the floor 2 side. The unevenness adjustment member 35 is elongated along the longitudinal direction of the floor side frame 31 and includes a base member 36 installed on the floor 2 and a height adjustment member 39 attached at multiple locations along the longitudinal direction of the base member 36 at intervals. The height adjustment member 39 is configured to be able to adjust the protruding height from the upper surface of the base member 36 and to support the floor side frame 31 so that the floor side frame 31 is arranged horizontally. With this configuration, the height of the height adjustment member 39 can be adjusted relative to the base member 36 so that the floor side frame 31 supported by the base member 36 is arranged horizontally, thereby allowing each partition panel 10 held by the floor side frame 31 to be installed at the same height. This improves workability compared to a device that requires adjustment of the adjuster bolts of each partition panel. This unevenness adjustment member 35 and the floor side frame 31 form the panel bottom end holding device 30.

The partition panel 10 is a generally rectangular flat plate that is long in the vertical direction. In this embodiment, the partition panel 10 has a vertical dimension that allows it to be installed with a space between it and the ceiling surface 3, as shown in Fig. 6(c). With this configuration, as in the above, the partition wall can be constructed without being affected by the framework on the ceiling side, and workability can be improved.
The vertical dimension (panel height dimension) of the partition panel 10 may be an appropriate dimension depending on the desired height of the partition wall constructed by the partition wall device 1, and may be, for example, about 1200 mm to 2400 mm. The width dimension of the partition panel 10 may be an appropriate dimension from the viewpoint of ease of handling and construction, and may be, for example, about 300 mm to 1500 mm. The thickness dimension of the partition panel 10 may be about 30 mm to 80 mm.

As shown in Fig. 2, the partition panel 10 is a so-called flush panel in which facing materials 13, 13 are provided on both sides in the panel thickness (wall thickness) direction of a panel core material 11 that is framed on all four sides. This configuration makes it possible to reduce the weight compared to a panel made of solid wood, etc. Note that one of the facing materials 13, 13 on both sides in the wall thickness direction of the partition panel 10 may be fixed at the construction site, or may be detachable from the panel core material 11.
The panel core material 11 includes an upper frame and a lower frame extending in the panel width direction at both ends in the vertical direction (panel height direction), and a pair of vertical frames extending in the panel width direction at both ends in the panel width direction. The panel core material 11 may be made of a wood-based material such as a wood laminate such as plywood or LVL (laminated veneer lumber), or may be made of a metal-based material. The panel core material 11 may also include a core material such as a paper honeycomb core, vertical bars, horizontal bars, etc.

The facing material 13 may be a general wall base board, for example, gypsum board (plasterboard), or may be a wood-based board such as an insulation board, MDF (medium density fiberboard), hardboard, or a wood-based board such as a wood laminate. The facing material 13 is not limited to such gypsum board or wood-based board, and may be a relatively thin metal plate such as an iron plate. The surface of the facing material 13 may be a decorative surface that has been appropriately treated by attaching a decorative sheet or painting.
The upper end protrusion 14 of the partition panel 10 is provided so as to protrude upward and extend over almost the entire width of the panel. The dimension of this upper end protrusion 14 along the panel thickness direction is smaller than that of the central portion in the up-down direction of the partition panel 10 so that a step is formed on both sides in the panel thickness direction. In this embodiment, this upper end protrusion 14 is formed by the upper end of the panel core material 11. In other words, this shows an example in which the facing materials 13, 13 are attached so as to expose the upper end of the panel core material 11, and the exposed upper end is used as the upper end protrusion 14.

The lower end protrusion 15 of the partition panel 10 is provided so as to protrude downward and extend over almost the entire width of the panel. Like the upper end protrusion 14, the dimension of the lower end protrusion 15 along the panel thickness direction is smaller than the vertical center portion of the partition panel 10 so that a step is formed on both sides in the panel thickness direction. In addition, an example is shown in which the surface materials 13, 13 are attached so as to expose the lower end of the panel core material 11, and the exposed lower end of the panel core material 11 is made into the lower end protrusion 15. Note that instead of the embodiment in which such an upper end protrusion 14 and a lower end protrusion 15 are provided, the upper end and lower end themselves of the partition panel 10, which are made uniform in thickness over the entire vertical direction, may be held by the upper frame 41 and the floor side frame 31 described later. Alternatively, an engaged portion such as an engaging groove corresponding to the engaging portion provided on the upper frame 41 and the floor frame 31 may be provided on the upper and lower ends of the partition panel 10.

In addition, both ends of the partition panel 10 in the panel width direction are provided with engagement recesses 16, 16 into which side portions of columnar connecting members 17, which will be described later, are fitted. With this configuration, as shown in Fig. 3(a) , by fitting each side portion of the columnar connecting member 17 in the wall width (panel width) direction into the engagement recesses 16, 16 of the adjacent partition panels 10, 10, it is possible to connect the adjacent partition panels 10, 10 in a manner that suppresses displacement in the wall thickness (panel thickness) direction.
The engagement recess 16 is formed in a groove shape that opens toward the outside in the panel width direction and extends over the entire panel height direction. The groove bottom of the engagement recess 16 is defined by the outer end face of the panel core material 11 in the panel width direction, and both sides of the groove width direction of the engagement recess 16 are defined by the face materials 13, 13 on both sides in the panel thickness direction. In other words, the face materials 13, 13 on both sides in the panel thickness direction are fixed to protrude toward the outside in the panel width direction beyond the panel core material 11, and the engagement recesses 16, 16 are provided at both side ends in the panel width direction. Note that instead of this embodiment, a groove that constitutes the engagement recess 16 may be provided at the side end of the panel core material 11 in the panel width direction.

2, the upper frame of the upper end of the panel core material 11 is provided with a wiring insertion hole 12 that penetrates vertically. With this configuration, the cable 4 inserted into this wiring insertion hole 12 can be connected to the equipment (interphone 6 in the illustrated example) installed in the partition panel 10, improving wiring workability. The illustrated example shows an example in which multiple (four in the illustrated example) wiring insertion holes 12 are provided at intervals in the panel width direction in the upper frame of the panel core material 11. Although not shown, a wiring insertion hole that penetrates vertically is also provided in the lower frame of the lower end of the panel core material 11. The illustrated example shows an example in which the cable 4 inserted into the wiring insertion hole of this lower frame is connected to an outlet (plug connector) 5. When a core material or a crosspiece is provided in the partition panel 10, it may be provided at an appropriate position so that the cable 4 inserted through the upper and lower wiring insertion holes 12 can be routed. The cable 4 may be a high-voltage cable (various power cables) or a low-voltage cable (LAN cable, optical fiber, telephone line, television line, or other communication line). The equipment installed in the partition panel 10 is not limited to the above-mentioned plug-in connector 5 and intercom 6, but may be various other equipment such as a switch (control panel), lighting equipment, and audio equipment.

As shown in FIG. 1, the columnar connecting member 17 is elongated in the vertical direction. As shown in FIG. 3(a), in this embodiment, the columnar connecting member 17 is configured such that both side portions in the wall width direction are fitted into the engagement recesses 16, 16 of the partition panels 10, 10 so that the center portion in the wall width direction is exposed between the adjacent partition panels 10, 10. In addition, the columnar connecting member 17 is configured to have an attachment recess 18a in the wall width direction center to which a support member 8 supporting a supported object 9 is attached. With this configuration, the supported object 9 can be supported on the front side of the partition panel 10 by attaching the support member 8 to the attachment recess 18a of the joint groove formed between the partition panels 10, 10.

In this embodiment, the columnar connecting member 17 is hollow tubular. With this configuration, it is possible to reduce the weight of the columnar connecting member 17. Also, mounting recesses 18a, 18a are provided in the tubular wall portions 18, 18 on both sides in the wall thickness direction of the columnar connecting member 17 so as to penetrate the respective tubular wall portions 18, 18. With this configuration, the support members 8 that support the supported object 9 can be attached to both sides in the wall thickness direction of the columnar connecting member 17.
In addition, a cushioning material 19 is inserted into the columnar connecting member 17. With this configuration, it is possible to prevent sound, light, and the like from leaking through the mounting recesses 18a, 18a on both sides in the wall thickness direction. In addition, the cushioning material 19 can reduce rattling of the insertion piece portion 8a of the support member 8 inserted into the mounting recess 18a.

In this embodiment, the columnar connecting member 17 is substantially rectangular tubular, and both side portions in the wall width direction form engaged portions that are fitted into the engaging recesses 16, 16 of the partition panels 10, 10. In other words, the center portion of the columnar connecting member 17 in the wall width direction is disposed so as to form the groove bottom of a joint groove formed between the end faces of the face materials 13, 13 of adjacent partition panels 10, 10.
The vertical dimension of this columnar connecting member 17 is approximately the same as the vertical dimension of the partition panel 10. Furthermore, the dimension of this columnar connecting member 17 along the wall thickness direction is approximately the same as the groove width dimension along the wall thickness direction of the engagement recess 16 of the partition panel 10. Furthermore, the dimension of this columnar connecting member 17 along the wall width direction is appropriately set according to the groove depth dimension along the wall width direction of the engagement recess 16 so that the central portion is exposed when both side portions are fitted into the engagement recesses 16, 16 of adjacent partition panels 10, 10.

Instead of the above-mentioned embodiment in which both side portions in the wall width direction are engaged portions that are fitted into the engaging recesses 16, 16, a configuration in which an appropriate convex or single-piece shaped engaged portion that is fitted into the engaging recesses 16, 16 may be provided on both side portions in the wall width direction of the columnar connecting member 17. Alternatively, instead of the embodiment in which the engaging recesses 16, 16 are provided on both side ends in the panel width direction of the partition panel 10, a convex portion may be provided and the columnar connecting member 17 may have a recess that receives the convex portion. Instead of the embodiment in which such a convex portion is provided on both side ends in the panel width direction of the partition panel 10, a configuration in which a recess that receives both side ends in the panel width direction of the partition panel 10 is provided on the columnar connecting member 17 may be provided.
This columnar connecting member 17 defines a hollow portion which is rectangular in shape when viewed in the longitudinal direction (approximately square in the illustrated example) by tubular wall portions 18, 18 on both sides in the wall thickness direction, which are plate-like with their thickness direction aligned in the wall thickness direction, and by both side wall portions on both sides in the wall width direction, which are plate-like with their thickness direction aligned in the wall width direction.

The mounting recess 18a is provided so as to be located at the center of the wall width direction of the tube wall portion 18. This mounting recess 18a is an elongated hole that is long in the vertical direction (see FIG. 1). In this embodiment, the columnar connecting member 17 is configured to have multiple mounting recesses 18a spaced apart in the vertical direction. With this configuration, the support member 8 that supports the supported object 9 can be provided at any height position, or multiple support members 8 can be provided at intervals in the vertical direction. These multiple mounting recesses 18a may be provided at equal intervals in the columnar connecting member 17. Note that the mounting recesses 18a are not shown in FIGS. 6(b) and (c).

The insertion piece 8a of the support member 8 inserted into the mounting recess 18a may be a plate-like piece with its thickness aligned along the wall width direction, and may be a hook-like piece with an appropriate anti-removal piece. The support member 8 may also be a bracket-like piece extending toward one side in the wall thickness direction. The illustrated example shows an example in which the support members 8, 8 are attached to the mounting recesses 18a, 18a of two columnar connecting members 17, 17 spaced apart in the wall width direction, and the supported object 9 is supported by bridging the support members 8, 8. The supported object 9 may be a shelf, a storage box, or any other type of equipment.

The cushion material 19 is provided so that it cannot be seen from one side in the wall thickness direction to the other side through the mounting recesses 18a, 18a on both sides in the wall thickness direction of the columnar connecting member 17. The cushion material 19 is compressed and deformed by the insertion piece portion 8a inserted through the mounting recess 18a, and is provided so as to surround the insertion piece portion 8a. The vertical dimension of this cushion material 19 may be approximately the same as the vertical dimension of the columnar connecting member 17. The dimensions of this cushion material 19 along the wall thickness direction and wall width direction may be approximately the same as the dimensions along the wall thickness direction and wall width direction of the hollow portion of the columnar connecting member 17. The cushion material 19 may be any material that has flexibility that allows compressive deformation, and may be formed from a resin foam such as urethane foam. It is also possible to configure the columnar connecting member 17 without providing such a cushion material 19 inside the columnar connecting member 17. Also, instead of the mounting recess 18a being a through hole, it may be a bottomed recess that opens outward in the wall thickness direction.

In addition, in this embodiment, the partition wall device 1 includes a columnar connecting member 17 having a mounting recess 18a and a columnar connecting member 17A having no mounting recess 18a. With this configuration, the columnar connecting member 17 having the mounting recess 18a and the columnar connecting member 17A having no mounting recess 18a can be selected and installed as needed. The columnar connecting member 17A is substantially rectangular tubular, and has the same configuration as the columnar connecting member 17 having the mounting recess 18a described above, except that the mounting recess 18a is not provided. Instead of this embodiment, a configuration in which only one of the columnar connecting member 17 having the mounting recess 18a and the columnar connecting member 17A having no mounting recess 18a is provided may be used.
In addition, in this embodiment, the columnar connecting members 17 (17A) are provided not only between adjacent partition panels 10, 10, but also between the pillars 20, 20 at both ends of the wall width direction and the partition panels 10, 10 adjacent to each of the pillars 20, 20.

The floor side frame 31 is elongated in the wall width direction as shown in Fig. 1. The length of the floor side frame 31 may be an appropriate dimension from the viewpoints of ease of handling and construction, and may be approximately an integral multiple of the panel width dimension of the partition panel 10, for example, about 600 mm to 4000 mm.
In this embodiment, as shown in Fig. 4(a), the floor side frame 31 is provided with a receiving groove 33 extending in the longitudinal direction, in which both inner walls 33a, 33a in the groove width direction are arranged to face both side surfaces 38a, 38a in the wall thickness direction of the base member 36 of the unevenness adjustment member 35. With this configuration, the height adjustment member 39 of the unevenness adjustment member 35 can be covered and hidden by both side pieces that define both sides in the groove width direction of the receiving groove 33 of the floor side frame 31. Also, by inserting the base member 36 into the receiving groove 33 of the floor side frame 31, it is easy to align the floor side frame 31 with the base member 36 along the wall thickness direction.
The receiving groove 33 is provided so as to open downward and extend over the entire length of the floor side frame 31, and has a substantially rectangular groove shape when viewed in the longitudinal direction of the groove.

In addition, in this embodiment, the floor side frame 31 is provided with an engagement groove 32 into which the lower end protrusion 15 of the partition panel 10 is fitted. With this configuration, the lower end protrusion 15 of the partition panel 10 can be fitted into the engagement groove 32 of the floor side frame 31 to suppress movement of the lower end side of the partition panel 10 in the panel thickness (wall thickness) direction. This engagement groove 32 is provided so as to open toward the upward side and extend over the entire length of the floor side frame 31, and is approximately a square groove shape when viewed in the groove longitudinal direction. In other words, in this embodiment, the floor side frame 31 is provided with an engagement groove 32 and a receiving groove 33 that open on both the upper and lower sides, and is H-shaped when viewed in the longitudinal direction. In the illustrated example, the groove width dimension of the engagement groove 32 and the groove width dimension of the receiving groove 33 are approximately the same dimension, and the groove depth dimension of the engagement groove 32 and the groove depth dimension of the receiving groove 33 are approximately the same dimension, but this is not limited to such an embodiment. The floor frame 31 may be made of a suitable metallic material.

The illustrated example shows an example in which decorative materials 31a, 31a are provided on both sides of the floor-side frame 31 in the wall thickness direction to cover both side surfaces in the wall thickness direction. In the illustrated example, the decorative materials 31a, 31a on both sides are shown as strip-shaped members with a relatively large dimension along the wall thickness direction, but they may also be in the form of a thin sheet. In addition, the surfaces of these decorative materials 31a, 31a facing outward in the wall thickness direction may be configured to be approximately flush with the surface facing outward in the wall thickness direction of the partition panel 10 whose lower end protrusion 15 is fitted into the engagement groove 32 of the floor-side frame 31.

The base member 36 of the unevenness adjustment member 35 has an upper piece 37 facing the groove bottom piece 34 that defines the groove bottom of the receiving groove 33 of the floor side frame 31, and both side pieces 38, 38 extending from both ends of the upper piece 37 in the wall thickness direction toward the floor 2 side. In addition, the groove bottom piece 34 of the floor side frame 31 and the upper piece 37 of the base member 36 are configured to have wiring insertion holes 34b, 37b that communicate with each other. With this configuration, as shown in FIG. 2, the space between the both side pieces 38, 38 of the base member 36 can be used as a wiring space. In addition, the cable 4 wired in the wiring space can be led out to the partition panel 10 side through the wiring insertion holes 34b, 37b of the groove bottom piece 34 of the floor side frame 31 and the upper piece 37 of the base member 36, and the cable 4 on the partition panel 10 side can be led out to the wiring space side.

The base member 36 is inserted so as to be fitted into the receiving groove 33 of the floor side frame 31. The dimension of the base member 36 along the wall thickness direction corresponds to the groove width dimension of the receiving groove 33. The dimension of the base member 36 along the vertical direction may be an appropriate dimension from the viewpoint of making the base member 36 fitted into the receiving groove 33 less noticeable or from the viewpoint of suppressing contact of the floor side frame 31 with the floor 2. The dimension of the base member 36 along the vertical direction may be an appropriate dimension so that the floor side frame 31 does not abut against the floor 2 in a state in which a height adjustment member 39 described later is provided on the base member 36 with a minimum protruding height. In the illustrated example, an example is shown in which the dimension of the base member 36 along the vertical direction is approximately the same as the groove depth dimension of the receiving groove 33, but this is not limited to such an embodiment. The length of the base member 36 may be an appropriate dimension from the standpoint of ease of handling and construction, and may be approximately the same as the length of the floor-side frame 31, or may be smaller than the length of the floor-side frame 31. The base member 36 may be made of an appropriate metallic material.

The wiring insertion hole 37b of the base member 36 is provided so as to penetrate the upper piece 37 in the thickness direction (vertical direction). The wiring insertion hole 34b of the floor side frame 31 is provided so as to penetrate the groove bottom piece 34 in the thickness direction (vertical direction). These wiring insertion holes 34b, 37b are provided so as to be in the same position as each other. In the illustrated example, the wiring insertion holes 34b, 37b are shown as elongated holes elongated in the wall width direction, but are not limited to this form. In addition, these wiring insertion holes 34b, 37b are provided at multiple locations at intervals in the longitudinal direction of the floor side frame 31 and the base member 36. In addition, these wiring insertion holes 34b, 37b are provided so as to communicate with the wiring insertion hole provided at the lower end of the partition panel 10 (see FIG. 2). In addition, the side piece 38 of the base member 36 and the side piece of the floor frame 31 may also be provided with wiring insertion holes that communicate with each other.
The base member 36 is provided with an attachment portion 37c to which the attachment receiving portion 39b of the height adjustment member 39 is attached. In the illustrated example, the attachment portion 37c is an attachment hole penetrating the upper piece portion 37 of the base member 36 in the thickness direction (vertical direction). Although the attachment portion 37c is an elongated hole elongated in the wall width direction, the present invention is not limited to this form. The attachment portion 37c is provided at a plurality of locations spaced apart in the longitudinal direction of the base member 36, as shown in FIG. 3B.

The floor side frame 31 and the base member 36 are provided with fastener insertion holes 34a, 37a through which the shafts of fasteners such as screws for fixing them to the floor 2 are inserted. The floor side frame 31 and the base member 36 may be fixed to the floor 2 by fasteners attached to the floor 2 through the fastener insertion holes 34a, 37a, or may be fixed to the floor 2 by adhesives, adhesives, etc. instead of or in addition to the fasteners. These fastener insertion holes 34a, 37a are provided so as to penetrate the groove bottom piece 34 and the upper piece 37 in the thickness direction, similarly to the above. These fastener insertion holes 34a, 37a are also provided so as to be in the same position as each other. In the illustrated example, the fastener insertion holes 34a, 37a are shown as elongated holes elongated in the wall width direction with the minor diameter smaller than the minor diameter of the wiring insertion holes 34b, 37b, but are not limited to such an embodiment. The fastener insertion holes 34a, 37a may be provided at multiple locations spaced apart in the longitudinal direction of the floor frame 31 and the base member 36, or may be provided at both longitudinal ends. The fastener insertion hole 37a and the mounting portion 37c of the base member 36 may be used interchangeably. The base member 36 has an upper piece 37 and both side pieces 38, 38, and is not limited to a roughly C-shape (roughly U-shape, roughly U-shape) with a downward opening when viewed in the longitudinal direction, but may be a square shape or other shape.

3B, in this embodiment, the height adjustment members 39 are configured from a plurality of types of height adjustment members 39A, 39B, 39C each having a spacer portion 39a with different height dimensions from the upper surface of the base member 36. With this configuration, the floor side frame 31 can be supported horizontally by selecting a height adjustment member 39 having a spacer portion 39a with an appropriate height dimension so that the floor side frame 31 is arranged horizontally and attaching the height adjustment member 39 to the base member 36.
The mounting portion 39b of the height adjustment member 39 is columnar and inserted into the mounting portion 37c of the base member 36. In the illustrated example, the mounting portion 39b is cylindrical, but is not limited to this. The mounting portion 39b may be press-fitted into the mounting portion 37c. The mounting portion 39b may be made of an elastic material such as rubber having a relatively high hardness.

The spacer portion 39a of the height adjustment member 39 is made larger in diameter than the attached portion 39b. In the illustrated example, the spacer portion 39a is made disk-shaped (cylindrical). In the illustrated example, the height adjustment member 39A in which the height dimension (dimension along the vertical direction) of the spacer portion 39a is small, the height adjustment member 39B in which the height dimension of the spacer portion 39a is medium, and the height adjustment member 39C in which the height dimension of the spacer portion 39a is large are illustrated. The spacer portion 39a may be made of an elastic material such as rubber with a relatively high hardness. The height adjustment member 39 is not limited to three types of height adjustment members 39A, 39B, and 39C in which the height dimensions of the spacer portion 39a are different, and may be provided with four or more types of height adjustment members. In addition, the spacer portion 39a may be a mode in which the height dimension is variable by adjusting the number of stacked layers of a multi-layer laminate that can be freely attached and detached from each other.

The unevenness adjustment member 35 is capable of absorbing the unevenness of the floor 2 by interposing a spacer portion 39a having an appropriate height dimension between the upper piece portion 37 of the base member 36 installed on the floor 2 and the groove bottom piece portion 34 of the floor side frame 31 so that the groove bottom piece portion 34 is horizontal. In other words, the unevenness adjustment member 35 is capable of absorbing the unevenness of the floor 2 by attaching an appropriate height adjustment member 39 to the base member 36 so that the floor side frame 31 is horizontal with respect to the base member 36 that is arranged at an angle due to the unevenness of the floor 2. Note that, although Fig. 3(b) shows an example in which the angle of inclination due to the unevenness of the floor 2 is relatively large, the present invention is not limited to such an embodiment.
In addition, as the panel lower end holding device 30 equipped with the unevenness adjustment member 35, instead of the one configured as described above, a panel lower end holding device 30A relating to a modified example shown in Figure 4 (b) may be adopted.

The panel lower end holding device 30A according to this modification is mainly different from the above-mentioned example in the configuration of the unevenness adjustment member 35A. In this modification, the height adjustment member 39D is provided with male threads 39d that are screwed into female threads 37d provided at intervals along the longitudinal direction on the upper surface side of the base member 36A. With this configuration, the protruding height of the height adjustment member 39D can be adjusted by adjusting the screwing amount of the male threads 39d of the height adjustment member 39D relative to the female threads 37d of the base member 36A. As a result, compared to the above-mentioned example, it is possible to reduce the number of parts while allowing fine adjustment of the protruding height, and improve the ease of handling.
The upper piece 37A of the base member 36A is provided with female threads 37d penetrating in the thickness direction and constituting an attachment portion. As described above, the female threads 37d are provided at a plurality of locations spaced apart in the longitudinal direction of the base member 36A. The female threads 37d may be formed by nuts that are integrally (fixedly) or separately provided to the upper piece 37A of the base member 36A.

The height adjustment member 39D is in the form of a bolt having a head 39c on the base end side of a male screw portion 39d. The head 39c is provided with an operating portion that is operated when screwing the male screw portion 39d of the height adjustment member 39D into the female screw portion 37d of the base member 36A. In the illustrated example, an example is shown in which the operating portion is in the form of a cross recess that engages with the tip of a screwdriver, but the present invention is not limited to this form.
In this unevenness adjustment member 35A, similarly to the above, the height adjustment member 39A is screwed to the base member 36A so that the floor side frame 31 is horizontal to the base member 36A, thereby making it possible to absorb unevenness in the floor 2. Note that the unevenness adjustment members 35, 35A are not limited to the above-mentioned embodiment, and various other modifications are possible.

The upper frame 41 is elongated in the wall width direction as shown in Fig. 2. The length of the upper frame 41 may be an appropriate dimension from the viewpoints of ease of handling and construction, and may be an approximate integral multiple of the panel width of the partition panel 10, for example, about 600 mm to 4000 mm. The length of the upper frame 41 may be approximately the same as the length of the floor side frame 31 described above.
In this embodiment, the upper frame 41 is provided with an engagement groove 42 into which the upper end protrusion 14 of the partition panel 10 is fitted. With this configuration, it is possible to suppress movement of the upper end side of the partition panel 10 in the wall thickness direction by fitting the upper end protrusion 14 of the partition panel 10 into the engagement groove 42 of the upper frame 41. This engagement groove 42 is provided so as to open downward and extend over the entire length of the upper frame 41, and has a substantially rectangular groove shape when viewed in the groove longitudinal direction.

In addition, in this embodiment, the upper frame 41 is provided with a receiving groove 43 that opens upward and extends over the entire length of the upper frame 41. With this configuration, the cable 4 can be accommodated in the receiving groove 43 of the upper frame 41. In other words, the upper frame 41 is provided with an engagement groove 42 and a receiving groove 43 that open on both the top and bottom sides, and is H-shaped when viewed in the longitudinal direction, similar to the floor frame 31 described above. In addition, the groove bottom piece 44 that defines the groove bottom of these engagement grooves 42 and receiving grooves 43 is provided with elongated wiring insertion holes 44b that are elongated in the longitudinal direction and spaced apart in the longitudinal direction so as to penetrate in the thickness direction, similar to the above. The wiring insertion holes 44b are provided so as to communicate with the wiring insertion holes 12 provided at the upper end of the partition panel 10. Note that the side pieces of the upper frame 41 may also be provided with wiring insertion holes.

In addition, the example shown in the figure shows an example in which the groove width dimension of the engagement groove 42 and the groove width dimension of the receiving groove 43 are approximately the same dimension, and the groove depth dimension of the engagement groove 42 and the groove depth dimension of the receiving groove 43 are approximately the same dimension, but is not limited to such an embodiment.
The figure shows an example in which the upper frame 41 is provided with decorative materials 41a, 41a on both sides in the wall thickness direction, similar to those described above, to cover both side surfaces in the wall thickness direction. The upper frame 41 and the floor frame 31 may be formed by appropriately cutting extruded members having a similar configuration. With such a configuration, it is possible to standardize parts and improve ease of handling.

The illustrated example shows an example in which a cover material 40 is provided so as to cover the receiving groove 43. With such a configuration, the cable 4 wired in the receiving groove 43 can be made less noticeable, and dust and the like can be made less likely to accumulate in the receiving groove 43. The cover material 40 is inserted so as to be fitted into the receiving groove 43. The cover material 40 has an upper piece and both side pieces extending from both ends of the upper piece in the wall thickness direction towards the floor 2, and is generally C-shaped (generally U-shaped or roughly U-shaped) with a downward opening when viewed in the longitudinal direction.
The illustrated example shows an example in which an illumination member 7 is attached to the upper surface of the cover material 40. With such a configuration, the illumination member 7 can function as indirect lighting for the upper end of the partition wall. The illumination member 7 is a so-called tape LED in which LEDs (light emitting diodes) serving as light sources are provided at intervals in the longitudinal direction on a tape-shaped substrate. The illumination member 7 is not limited to such a configuration, and may have various other configurations. Also, the illumination member 7 may not be provided, and the cover material 40 may not be provided.

As shown in FIG. 1, the pair of pillars 20, 20 are substantially rectangular pillars elongated in the vertical direction. The vertical dimensions of the pillars 20, 20 correspond to the vertical dimensions of the partition panel 10. That is, in this embodiment, the pillars 20, 20 are vertically sized to be installed with a space between them and the ceiling surface 3, as shown in FIG. 6(c). With this configuration, a space can be formed above the partition wall constructed by the partition wall device 1. This makes it possible to share equipment such as air conditioning and lighting in the spaces on both sides of the partition wall in the wall thickness direction. In other words, the need to relocate equipment can be reduced when changing the layout. Since the pillars 20, 20 have the same configuration, the following description will be given by taking one of them as an example.
3(a) and 4(a), a receiving groove 21 is provided on all four sides of the support 20 to receive a support-side piece 28 of a fastener 27 that fastens the upper frame 41 and/or the floor-side frame 31. In addition, a groove-filling member 25 is provided on all four sides of the support 20 so as to be detachable and cover the receiving groove 21.

With the above-mentioned configuration, both or one of the upper frame 41 and floor frame 31 can be fixed to the support 20 via the fastener 27 whose support side piece 28 is received in the receiving groove 21 of the support 20. In addition, the support side piece 28 of the fastener 27 does not protrude from the side of the support 20, and interference between the support side piece 28 and other members (in this embodiment, the column-shaped connecting members 17, 17A) can be suppressed. In addition, the receiving groove 21 can be provided by removing the groove filling member 25 of the side that needs to fix both or one of the upper frame 41 and floor frame 31 among the four sides of the support 20. This allows the support 20 to be flexibly installed regardless of the number of frames fixed or the installation direction.

For example, as shown in Fig. 1 and Fig. 3(a), a fastener 27 can be attached to a receiving groove 21 provided by removing a groove filling member 25 from one of the four circumferential sides of a support 20. By providing a partition panel 10 on the groove opening side of the receiving groove 21, a partition wall extending toward the groove opening direction of the receiving groove 21 can be constructed. Also, as shown in Fig. 5(a), fasteners 27, 27 can be attached to receiving grooves 21, 21 provided by removing groove filling members 25, 25 from two mutually intersecting sides of the four circumferential sides of the support 20. By providing partition panels 10, 10 on the groove opening sides of these receiving grooves 21, 21, a partition wall that is approximately L-shaped in plan view can be constructed. Also, as shown in FIG. 5B, the fasteners 27, 27, 27 can be attached to the receiving grooves 21, 21, 21 that are provided by removing the groove-filling members 25, 25, 25 on three of the four sides of the support 20. As a result, by providing partition panels 10, 10, 10 on the groove opening sides of these receiving grooves 21, 21, 21, a partition wall that is approximately T-shaped in plan view can be constructed. Also, although not shown, the fasteners 27, 27, 27, 27 can be attached to the receiving grooves 21, 21, 21, 21 that are provided by removing the groove-filling members 25, 25, 25, 25 on all four sides of the support 20. As a result, by providing partition panels 10, 10, 10, 10 on the groove opening sides of these receiving grooves 21, 21, 21, 21, a partition wall that is approximately +-shaped in plan view can be constructed.

The receiving grooves 21 are provided so as to open on each side surface of the four circumferences of the support 20. In this embodiment, the receiving grooves 21 are provided so as to extend over the entire length of each side surface of the four circumferences of the support 20. Note that the receiving grooves 21 and groove filling members 25 on each side surface of the four circumferences have the same configuration, so the following description will be given by taking one as an example.
The receiving groove 21 is configured to receive the column side pieces 28, 28 of the fasteners 27, 27 that fix the upper frame 41 and the floor side frame 31 to the column 20. The receiving groove 21 also functions as an engagement recess into which the side of the column-shaped connecting member 17, 17A described above is fitted. With this configuration, the column 20 and the partition panel 10 can be connected via the column-shaped connecting member 17, 17A, and the gap between them can be blocked by the column-shaped connecting member 17, 17A. Furthermore, the column-shaped connecting member 17, 17A can suppress displacement of the partition panel 10 relative to the column 20 in the wall thickness direction.

The groove opening side of the receiving groove 21 is provided with protruding pieces 22, 22 protruding in opposing directions from both sides in the groove width direction. These protruding pieces 22, 22 are provided so as to make the groove width dimension of the receiving groove 21 smaller on the groove opening side than on the groove bottom side.
The groove width dimension of the groove opening side of the receiving groove 21 corresponds to the dimension along the wall thickness direction of the columnar connecting member 17, 17A. The groove depth dimension of the receiving groove 21 is appropriately set so that the center portion is exposed when the side portion of the columnar connecting member 17, 17A is fitted into the groove.
The bottom of the receiving groove 21 is defined by an axial center side columnar portion 23 provided on the axial center side of the support 20. A fastener such as a screw for fixing the fixture 27 to the support 20 may be attached to this axial center side columnar portion 23. The illustrated example shows an example in which a hollow portion is provided through the entire length of the axial center portion of the axial center side columnar portion 23, which is substantially rectangular prism-shaped.

The groove filling member 25 is mounted in the receiving groove 21 so that the surface facing the outer periphery of the support 20 is substantially flush with the side surface of the support 20. The dimension of this groove filling member 25 along the groove depth direction of the receiving groove 21 is substantially the same as the groove depth dimension of the receiving groove 21. In addition, the dimension of this groove filling member 25 along the groove width direction of the receiving groove 21 is substantially the same as the groove width dimension of the groove opening side of the receiving groove 21. In the illustrated example, the groove filling member 25 is substantially rectangular when viewed in the longitudinal direction of the support 20. The groove filling member 25 may be removably fixed to the groove bottom of the receiving groove 21 by, for example, an adhesive or a sticky material.
Also, a suitable decorative sheet is attached to each side surface of the four periphery of the support 20. In the illustrated example, a decorative sheet is attached in a continuous manner to the surfaces at the four corners of the support 20, the tip surface of the protruding piece 22, and the surface of the tip of the protruding piece 22 facing the axial center side. A decorative sheet of the same color and pattern may also be attached to at least the surface of the groove filling member 25 facing the outer periphery of the support 20. Also, a decorative sheet may be attached in a continuous manner to the side surfaces of the four periphery of the support 20, including the surface of the groove filling member 25 facing the outer periphery of the support 20. In this case, the groove filling member 25 may be removable by cutting off the decorative sheet.

In addition, as shown in FIG. 4(a), the upper end of the support 20 is provided with an upper end recess 24 that communicates the receiving grooves 43 of the multiple upper frames 41 fixed to the upper end of the support 20 (see also FIG. 1). With this configuration, the cable 4 wired to the receiving grooves 43 of the multiple upper frames 41 fixed to the upper end of the support 20 can be wired through the upper end recess 24 without being cut off by the support 20. This upper end recess 24 is provided so as to open on each side surface around the upper end of the support 20 and to penetrate the support 20 in a direction perpendicular to each side surface. In addition, the upper end recess 24 is provided in a cutout shape so as to open toward the upper side. In addition, as shown in FIG. 1, a configuration may be made in which a cover material is provided to cover the upper end recess 24 on the side to which the upper frame 41 is not fixed. In addition, the support 20 may be formed from an appropriate metal material. The groove filling member 25 may be made of the same material as the support 20, or may be made of a synthetic resin material, etc.

The columns 20 are connected to the upper frame 41 and the lower frame 31 in a vertical direction. The fixtures 27 for fixing the upper frame 41 to the columns 20 and the fixtures 27 for fixing the floor frame 31 to the columns 20 are the same parts.
The fixture 27 includes a pillar side piece 28 that is fixed to the pillar 20, and a frame side piece 29 that is fixed to the upper frame 41 and the lower frame 31. In the illustrated example, the fixture 27 is shown to be substantially L-shaped when viewed in the wall thickness direction.
The pillar side piece 28 is formed in a plate shape with its thickness direction aligned along the wall width direction, and is configured to be arranged along the groove bottom of the receiving groove 21 of the pillar 20. In the illustrated example, the dimension along the wall thickness direction of this pillar side piece 28 is made larger than the groove width dimension on the groove opening side, and corresponds to the groove width dimension of the groove bottom of the receiving groove 21.
Further, the pillar side piece 28 is provided with an insertion hole through which the shaft of a fastener such as a screw is inserted. The pillar side piece 28 is fixed to the pillar 20 by a fastener attached to the axis-side columnar portion 23 via the insertion hole.

The frame side piece 29 is a plate-like member with its thickness aligned in the vertical direction, and is arranged to fit along the groove bottom pieces 44, 34 of the upper frame 41 and the lower frame 31. The frame side piece 29 may be arranged to fit along one of the upper and lower surfaces of the groove bottom pieces 44, 34 of the upper frame 41 and the lower frame 31. The frame side piece 29 is provided with an insertion hole through which the shank of a fastener such as a screw is inserted. The frame side piece 29 is fixed to the upper frame 41 and the lower frame 31 by a fastener attached to the groove bottom pieces 44, 34 via the insertion hole.
In addition, the frame side piece 29 has an engagement portion 29a, 29a at its base end on the support side piece 28 side, which engages with the protruding piece 22, 22 provided on the groove opening side of the receiving groove 21 to suppress the movement of the fixture 27 toward the receiving groove 21 opening side. In the illustrated example, the tip side of the frame side piece 29 has a dimension corresponding to the dimension along the wall thickness direction of the groove bottom piece 44, 34, and the engagement portion 29a, 29a is step-shaped, but this is not limited to this embodiment. For example, the engagement portion 29a, 29a may be a notched recess shape that receives the protruding piece 22, 22. The fixture 27 may be made of an appropriate metal material. The fixture 27 for fixing the upper frame 41 and the floor side frame 31 to the support 20 is not limited to the above-mentioned configuration, and may have various other configurations.

As shown in Fig. 4(a), the partition wall device 1 is provided with a fixed base 26 for fixing the lower end of the support 20 to the floor 2. In other words, the lower end of the support 20 is fixed to the floor 2 via the fixed base 26. The fixed base 26 is configured to be arranged so as to overlap the support 20 in a plan view. With this configuration, the appearance can be improved compared to a configuration in which the lower end of the support 20 is fixed to the floor 2 via a fixing piece that protrudes outward from the lower end of the support 20.
The fixed base 26 includes a base portion 26a fixed to the floor 2 by a fastener such as a screw, an adhesive, or a sticky material, and an engagement portion 26b engaged with the support 20. In the illustrated example, the engagement portion 26b is a convex portion inserted so as to be fitted through the lower end opening of the receiving groove 21 provided on each side of the four circumferences of the support 20. Note that instead of such a configuration, a configuration may be used in which the engagement portion 26b is provided so as to be fitted through the lower end opening of the hollow portion of the axis-side columnar portion 23. The support 20 may be configured to be self-supporting by having its lower end held by the fixed base 26 fixed to the floor 2. Note that the manner in which the lower end side of the support 20 is fixed to the floor 2 is not limited to the above configuration, and may be, for example, fixed to the floor 2 via a floor-side frame 31 fixed to the floor 2.

The partition wall device 1 configured as above may be constructed as follows by the partition wall construction method according to this embodiment, as shown in FIG.
6(a), this partition wall construction method includes a step of installing the first support 20A with its lower end fixed to the floor 2. At this time, the above-mentioned fixed base 26 may be fixed to the floor 2, and then the first support 20A may be installed on the floor 2 with its lower end held by the fixed base 26.
The partition wall construction method also includes a step of arranging a floor side frame 31 extending in the wall width direction so as to connect the first end to the lower end of the first support 20A. At this time, the floor side frame 31 may be held on the base member 36 of the unevenness adjustment member 35 arranged on the floor 2 to check the horizontal level of the floor side frame 31, and the floor side frame 31 may be installed so as to be horizontal using the height adjustment member 39 described above as necessary. The floor side frame 31 (and the base member 36) may also be fixed to the floor 2 by a fastener such as a screw, an adhesive, a sticky material, or the like. The first end of the floor side frame 31 and the lower end of the first support 20A are connected by a fixing device 27. Note that the fixing device 27 may be engaged and fixed in the receiving groove 21 of the first support 20A before the lower end side of the first support 20A is held by the fixed base 26. Alternatively, the fixing device 27 may be fixed to the floor side frame 31 side in advance.

As shown in Fig. 6(b), the partition wall construction method includes a step of arranging a plurality of partition panels 10, 10 by interposing a columnar connecting member 17 between adjacent partition panels 10, 10 and holding the lower end protrusions 15 of each panel to the floor frame 31. In this embodiment, a columnar connecting member 17A is also interposed between the first support 20A and the adjacent partition panel 10. First, one side of the columnar connecting member 17A is fitted into the receiving groove 21 of the first support 20A to install the columnar connecting member 17A, and then the other side of the columnar connecting member 17A is fitted into one of the engagement recesses 16 to install the partition panel 10. Also, the columnar connecting member 17 may be installed by fitting one side of the columnar connecting member 17 into the other engagement recess 16 of the partition panel 10, and then the next partition panel 10 may be installed by fitting the other side of the columnar connecting member 17 into one of the engagement recesses 16. Thereafter, the partition panels 10 and the columnar connecting members 17 may be installed in the same manner. In this case, although not shown in the figure, the columnar connecting member 17 provided with the mounting recess 18a and the columnar connecting member 17A without the mounting recess 18a may be appropriately selected and installed.

The partition wall construction method also includes a step of installing the second support 20B by fixing its lower end to the floor 2 side so as to connect the lower end to the second end of the floor-side frame 31. In this case, as described above, the fixed base 26 may be fixed to the floor 2, and then the second support 20B may be installed on the floor 2 with the lower end of the second support 20B held by the fixed base 26, and the lower end of the second support 20B may be connected to the second end of the floor-side frame 31 by the fixing device 27. As described above, the fixing device 27 may be fixed to the second support 20B or the floor-side frame 31 in advance. In this embodiment, a column-shaped connecting member 17 is also interposed between the second support 20B and the partition panel 10 adjacent thereto.
The partition wall construction method also includes a step of fixing each longitudinal end of the upper frame 41, which holds the upper end protrusion 14 of the partition panel 10, to the upper ends of the first support 20A and the second support 20B, as shown in Fig. 6(c). At this time, the fasteners 27 for fixing each longitudinal end of the upper frame 41 to the upper ends of the first support 20A and the second support 20B may be fixed in advance to the first support 20A and the second support 20B or the upper frame 41. In addition, when the partition panel 10 is provided with various equipment (in the illustrated example, the intercom 6 and the plug connector 5) as described above, the cables 4 may be wired in the upper frame 41, the floor frame 31, and the partition panel 10.

In addition, after installing multiple partition panels 10, 10 in the wall width direction between a pair of supports 20, 20 (first support 20A and second support 20B) in this way, multiple partition panels 10, 10 may be installed along the wall width direction. In other words, in this case, a partition wall is constructed by multiple partition panels 10, 10 on both sides of the second support 20B in the wall width direction. In addition, multiple partition panels 10, 10 may be installed so that a partition wall is constructed between a pair of supports 20, 20 (first support 20A and second support 20B) that is perpendicular in plan view to the partition wall constructed by multiple partition panels 10, 10 (see Figure 5). Note that the above installation procedure is merely one example, and various modifications are possible.

The above example shows a partition wall constructed so that a space is formed between it and the ceiling surface 3, but one modified example of the partition wall device 1 according to this embodiment makes it possible to construct a partition wall all the way up to the ceiling surface 3.
As shown in Fig. 7(a), the partition wall device 1 includes a pair of auxiliary supports 20C, 20C attached to the upper side of the pair of supports 20, 20, with their upper ends abutting the ceiling surface 3. The partition wall device 1 also includes a ceiling-side frame 48 arranged along the ceiling surface 3 so as to extend between the pair of auxiliary supports 20C, 20C, and a board fixing member 45 arranged between the ceiling-side frame 48 and the upper frame 41 and capable of expanding and contracting in the vertical direction. The partition wall device 1 also includes auxiliary boards 13A, 13A fixed to both sides of the board fixing member 45 in the wall thickness direction so as to close the space between the ceiling-side frame 48 and the upper frame 41.

With the above-mentioned configuration, the space between the ceiling-side frame 48 and the upper frame 41 can be blocked by the auxiliary boards 13A, 13A fixed to both sides of the board fixing member 45 in the wall thickness direction. This allows the installation to be performed without being affected by the ceiling-side structure as described above, while also allowing for cases where a partition wall is to be constructed up to the ceiling surface 3 for light blocking, sound blocking, etc. Also, by expanding and contracting the board fixing member 45, even if there is unevenness in the ceiling surface 3, the unevenness can be absorbed and the ceiling-side frame 48 can be installed along the ceiling surface 3. Also, if the pair of auxiliary supports 20C, 20C, the ceiling-side frame 48, the board fixing member 45, and the auxiliary boards 13A, 13A are not installed, a space can be formed above the partition wall constructed by the partition wall device 1 as described above.

The auxiliary support 20C has a configuration generally similar to that of the support 20 described above. The auxiliary support 20C may be formed by appropriately cutting a long member that will become the extruded support 20. With such a configuration, it is possible to standardize parts. The auxiliary support 20C and the support 20 may be connected by an appropriate connector. The auxiliary support 20C may be fixed by engaging a fixing device 27 similar to the above that connects the auxiliary support 20C and the ceiling side frame 48 with the receiving groove 21 of the auxiliary support 20C. The auxiliary support 20C may also be configured to have a fixing base 26 similar to the above that fixes the upper end of the auxiliary support 20C to the ceiling surface 3.

The ceiling frame 48 is elongated in the wall width direction. The ceiling frame 48 is provided with a receiving groove 49 that receives the upper end protrusion 46b of the board fixing member 45. The receiving groove 49 is provided so as to open downward and extend over the entire length of the ceiling frame 48, and is approximately rectangular when viewed in the groove longitudinal direction. The receiving groove 49 of the ceiling frame 48 is defined by an upper piece and both side pieces extending downward from both ends of the upper piece in the wall thickness direction. The auxiliary boards 13A, 13A on both sides in the wall thickness direction are fixed to both sides of the ceiling frame 48 in the wall thickness direction. The dimension of the ceiling frame 48 along the wall thickness direction may be an appropriate dimension so that the surface of the auxiliary boards 13A, 13A facing outward in the wall thickness direction is approximately flush with the surface of the partition panel 10 facing outward in the wall thickness direction. The ceiling-side frame 48 may be fixed along the ceiling surface 3 with fasteners such as screws, adhesives, or pressure-sensitive adhesives. The ceiling-side frame 48 may be made of a metal material, but may also be made of a synthetic resin material so that it can conform to the unevenness of the ceiling surface 3.

7B, in this embodiment, the board fixing member 45 has a double cylindrical structure that is expandable in the vertical direction. The board fixing member 45 includes a main body 46 that constitutes an outer cylindrical portion, and an expandable portion 47 that is fitted into the main body 46 and constitutes an inner cylindrical portion.
The auxiliary boards 13A, 13A on both sides in the wall thickness direction are fixed to both sides of the main body 46 in the wall thickness direction. The dimensions of the main body 46 along the wall width direction and the vertical direction may be appropriately determined so that the auxiliary boards 13A, 13A on both sides in the wall thickness direction can be stably fixed. The dimensions of the main body 46 along the wall thickness direction may be appropriately determined so that the surfaces of the auxiliary boards 13A, 13A facing outward in the wall thickness direction are approximately flush with the surfaces of the partition panel 10 facing outward in the wall thickness direction.
Further, an upper end protrusion 46b is provided at the upper end of the main body 46, which is fitted into a receiving groove 49 of the ceiling-side frame 48. The upper end protrusion 46b is provided so as to form a step on both sides of the upper end of the main body 46 in the wall thickness direction.

A portion of the expandable portion 47 is housed within the main body portion 46 via a lower opening of the main body portion 46, and the expandable portion 47 expands and contracts relative to the main body portion 46. A lower end of the expandable portion 47 is inserted into the receiving groove 43 of the upper frame 41. The lower end of the expandable portion 47 may be provided with a receiving recess for receiving the cable 4 wired in the receiving groove 43 of the upper frame 41.
The telescopic section 47 and the main body section 46 are provided with fasteners 46a and multiple female threaded sections 47a which constitute a fixing section and a fixed section for fixing the telescopic position of the telescopic section 47 relative to the main body section 46. In the illustrated example, multiple female threaded sections 47a are provided at intervals in the vertical direction on both sides in the wall width direction of the telescopic section 47, and fasteners 46a having male threaded sections which screw into the female threaded sections 47a of the telescopic section 47 are provided on both sides in the wall width direction of the main body section 46, but the present invention is not limited to this embodiment.

This board fixing member 45 may be provided so as to be located directly above the columnar connecting member 17 provided between the partition panels 10, 10. The surface of this board fixing member 45 may be the same color as the surface of the columnar connecting member 17. This board fixing member 45 may be formed from a metal material or a synthetic resin material. The expansion and contraction structure of the board fixing member 45 is not limited to the above-mentioned structure, and may be, for example, one provided with an adjuster bolt-like member, or may have various other structures.
The auxiliary boards 13A, 13A fixed to both sides of the board fixing member 45 in the wall thickness direction may have the same configuration as the face material 13 of the partition panel 10. In the illustrated example, the dimension of the auxiliary board 13A along the wall width direction is approximately the same as the dimension along the wall width direction of the face material 13 of the partition panel 10 so that a similar joint groove is formed approximately directly above the joint groove between the partition panels 10, 10. Note that instead of this embodiment, the auxiliary board 13A may be provided in a continuous manner across the auxiliary supports 20C, 20C.

Next, an example of a partition wall structure using the above-mentioned partition wall device 1 will be described with reference to Fig. 8. Note that, in the example of Fig. 8, an example is shown in which the partition wall is constructed so as to form a space between the partition wall and the ceiling surface 3, but some or all of the partition walls may be partition walls that reach the ceiling surface 3 as described above.
This partition wall structure 50 is structured by installing a plurality of partition blocks 53-56 in which the partition panels 10, 10 are connected to each other so as to be perpendicular to each other in a plan view. With this configuration, the partition blocks 53-56 are structured by connecting the partition panels 10, 10 to each other so as to be perpendicular to each other in a plan view, so that the installation stability of the partition blocks 53-56 can be improved.

In addition, the partition wall structure 50 has the first partition block 53 and the second partition block 54 of the multiple partition blocks 53 to 56, which are connected to each other via the first connecting member 51 and are installed at a distance in the first direction. In addition, the partition wall structure 50 has the third partition block 55 installed at a distance in the second direction perpendicular to the first direction and connected to the first partition block 53 and the second partition block 54, which are connected to each other via the first connecting member 51, via the second connecting member 52. With this configuration, the partition blocks 53 to 56, each of which has the partition panels 10, 10 arranged perpendicularly, are arranged at positions spaced apart in the first and second directions perpendicular to each other via the connecting members 51, 52. This improves stability even when a load is applied along the first or second direction, and effectively suppresses the overturning of the partition blocks 53 to 56. That is, as described above, even when the lower end of the support 20 is engaged and held by the fixed base 26 and the lower end protrusion 15 of the partition panel 10 is engaged and held by the engagement groove 32 of the floor-side frame 31, it is possible to make the support 20 and the partition panel 10 less likely to tip over. In other words, the support 20 and the partition panel 10 can be easily installed without directly fixing the lower end side of the support 20 and the partition panel 10 to the floor 2, and yet tipping over can be prevented.

In this embodiment, the first connecting member 51 and the second connecting member 52 are connected to the upper ends of the respective connection targets. With this configuration, the stability can be improved and the partition blocks 53 to 56 can be more effectively prevented from falling over, compared to when the first connecting member 51 and the second connecting member 52 are connected to the middle part in the height direction or the lower end part of the respective connection targets. Also, the first connecting member 51 and the second connecting member 52 can be prevented from getting in the way.
In this embodiment, the above-mentioned support pillars 20 are provided at the intersections of the partition panels 10, 10 in the partition blocks 53 to 56 and at the outer end of the partition panel 10 in the panel width direction. Also, the longitudinal ends of the first connecting member 51 and the second connecting member 52 are connected to the support pillars 20. With this configuration, both longitudinal ends of each connecting member 51, 52 are connected to the support pillars 20, which allows for a stronger connection than when the connecting members 51, 52 are connected to the upper end of the partition panel 10, thereby further improving stability.

One or both of the first connecting member 51 and the second connecting member 52 are provided so as to extend outward in the panel width direction from one end side in the panel width direction of any of the partition panels 10 constituting the partition blocks 53 to 56 to be connected at least on one end side in the longitudinal direction. With this configuration, the longitudinal direction of one or both of the first connecting member 51 and the second connecting member 52 is along the panel width direction of the partition panel 10, so that stability can be improved compared to a case where the first connecting member 51 and the second connecting member 52 are connected in the panel thickness direction to a middle portion in the panel width direction.
The first and second connecting members 51 and 52 are configured in the same manner as the upper frame 41 described above. That is, the first and second connecting members 51 and 52 are provided with an engagement groove 42 (see FIG. 2, etc.) that opens downward and a receiving groove 43 (see FIG. 2, etc.) that opens upward. With this configuration, the cable 4 can be wired in the receiving groove 43 of the first and second connecting members 51 and 52. In addition, the first and second connecting members 51 and 52 and the upper frame 41 may be formed by appropriately cutting extruded members having the same configuration. With this configuration, it is possible to standardize parts and improve handleability.
The longitudinal ends of the first connecting member 51 and the second connecting member 52 may be connected to the support pillars 20 by the same fasteners 27 as described above. The upper and lower ends of the partition panels 10 of each of the partition blocks 53 to 56 are provided with the upper frame 41 and the floor frame 31 (panel lower end holding device 30) described above.

The partition blocks 53 to 56 are structured by connecting the partition panels 10, 10 so that they have any one of an L-shape, a T-shape, a C-shape, and a square shape in plan view. With this configuration, the partition blocks 53 to 56 can be installed in an installation manner according to the installation location.
In the illustrated example, the first partition block 53 is rectangular in plan view. Also, the first partition block 53 is square in plan view. Each side of the first partition block 53 is made up of three partition panels 10, which are connected by supports 20 at the four corners. Any side of the first partition block 53 may be provided with an entrance and fittings such as a sliding door or hinged door for opening and closing the entrance. Such fittings may be installed in place of any of the partition panels 10, or the fittings may be unitized with the partition panel 10.

Also shown is an example in which the second partition block 54 connected to the first partition block 53 via the first connecting member 51 is T-shaped in plan view. In the illustrated example, a support 20 provided at one end of the horizontal side of the T-shaped second partition block 54 and a support 20 provided at one corner of the first partition block 53 are connected by the first connecting member 51. Also, the longitudinal direction of the first connecting member 51 is aligned with the panel width direction of the partition panel 10 constituting one side of the first partition block 53 and the partition panel 10 constituting the horizontal side of the second partition block 54.
In addition, the second partition block 54 has a structure in which a support 20 is provided at the intersection between the horizontal side and the vertical side of the second partition block 54. In the illustrated example, the horizontal sides on both sides of the support 20 at this intersection are each formed of four partition panels 10, but this is not limited to this embodiment. In addition, the vertical side of the second partition block 54 is formed of three partition panels 10, but this is not limited to this embodiment.

Also, an example is shown in which the third partition block 55 is C-shaped (U-shaped, U-shaped) in plan view. Also, an example is shown in which each side of the C-shaped third partition block 55 is composed of three partition panels 10, but this is not limited to this form. Also, a structure is formed in which a support 20 provided at the intersection of the mutually orthogonal sides of the third partition block 55 and a support 20 provided at one end of the horizontal side of the second partition block 54 are connected by a second connecting member 52. Also, a structure is formed in which the longitudinal direction of this second connecting member 52 is aligned with the panel width direction of the partition panel 10 that constitutes one side of the third partition block 55. Also, a structure is formed in which this second connecting member 52 and the first connecting member 51 are arranged perpendicular to each other via a support 20 provided at one end of the horizontal side of the second partition block 54.

In addition, in this embodiment, the fourth partition block 56 is installed spaced apart in the second direction while being connected to the second partition block 54 via the second connecting member 52.
Also, this fourth partition block 56 is shown as an example having an L-shape in plan view. Also, this example shows an example in which each side of the L-shaped fourth partition block 56 is formed by three partition panels 10, but this is not limited to such an embodiment. Also, a structure is formed in which a support 20 provided at the outer end of one side of the fourth partition block 56 and a support 20 at the intersection of the second partition block 54 are connected by a second connecting member 52. Also, a longitudinal direction of this second connecting member 52 is aligned along the panel width direction of the partition panel 10 that constitutes one side of the fourth partition block 56, and aligned along the panel width direction of the partition panel 10 that constitutes the vertical side of the second partition block 54.

The first connecting member 51 and the second connecting member 52 are not limited to those having the same configuration as the upper frame 41, and may have various other configurations. Furthermore, the connection target of each end of the first connecting member 51 and the second connecting member 52 is not limited to the upper end of the support 20, but may be the lower end or a vertical intermediate portion of the support 20, the upper frame 41 or partition panel 10 constituting each partition block 53 to 56, the floor side frame 31, etc.
In addition, in this embodiment, an example is shown in which four partition blocks 53 to 56 having different shapes in plan view are provided, but all or some of them may have the same shape in plan view. In addition, an example is shown in which four partition blocks 53 to 56 are provided, but the partition block may have at least a first partition block, a second partition block, and a third partition block, or may have five or more partition blocks. In addition, the partition wall structure 50 using the partition wall device 1 according to this embodiment is not limited to the above example, and various other modifications are possible. In addition, in this embodiment, an example is shown in which an unevenness adjustment member 35 that supports the floor side frame 31 horizontally is provided, but such an unevenness adjustment member 35 may not be provided. The configurations of the members and parts of the partition wall device 1 according to this embodiment are not limited to the above configurations, and various other modifications are possible.
