Summary of the Invention

Problems to be Solved by the Invention

[0004] In the space structure described in Patent Document 1, a plurality of C-shaped grooves are formed on both side surfaces of the beam, and although it is convenient to attach a frame material or a cover member for supporting the upper end portion of an optional member such as a slide panel, since the beam is manufactured by extrusion molding of an aluminum material to form this shape, the material cost is high. Further, since projecting pieces are integrally continuously provided on both side edge portions of the upper and lower surfaces of the beam, the cross-sectional shape of the beam becomes complicated, and the manufacturing cost of the mold for extrusion molding also increases, resulting in an increase in the cost of the beam.

[0005] This invention addresses these problems and aims to provide a spatial structure that reduces the cost of beams and allows for easy attachment of optional components to the beams without requiring any special processing. [Means for solving the problem]

[0006] To solve the above problems, the spatial structure of the present invention is In a spatial structure comprising multiple support columns whose lower ends are supported by the floor surface, and beams connecting the upper ends of adjacent support columns, The beam is formed from a rectangular tube, and a side mounting member is attached to at least one side of the beam, the lower end of which extends downward from the lower surface of the beam, and the extension portion of the side mounting member that extends downward from the lower surface of the beam is used as a mounting portion for an optional member. This feature allows the beam to be formed from a square tube, resulting in an extremely simple cross-sectional shape. This not only enables the beam to be manufactured inexpensively, but also allows the use of readily available, inexpensive steel square tubes, thus reducing beam costs. Furthermore, by using the extension portion of the side mounting member that extends downward from the underside of the beam as the mounting portion for optional components, there is no need to perform any special processing on the beam to attach the optional components, and the optional components can be easily attached to the mounting portion without interfering with the beam.

[0007] The aforementioned side mounting member is characterized by being formed in a hollow shape by fixing inward-facing pieces formed on the upper and lower edges of two metal plates together. This feature allows for weight reduction while ensuring the strength of the side mounting components.

[0008] The upper end of the side mounting member is characterized by extending to the upper end of the beam. This feature increases the mounting area of ​​the side mounting member on the side of the beam, thereby increasing the mounting strength of the side mounting member on the side of the beam.

[0009] A side mounting member is also attached to the other side of the beam so as to extend downward from the lower surface of the beam, and the space enclosed by the extension of this other side mounting member, the mounting portion of the one side mounting member, and the lower surface of the beam is characterized in that it is used as a mounting space for an optional member other than the optional member. This feature allows for the attachment of different optional components to the mounting space below the beam and to the mounting portion of the side mounting member attached to one side of the beam, thereby increasing the range of optional component options.

[0010] Within the aforementioned mounting space, a lower mounting member with a downward-facing U-shaped cross-section is attached to the lower surface of the beam, to which the upper end of the other optional member can be attached. This feature allows the upper end of the optional component to be attached to the underside of the beam via a lower mounting member, eliminating the need to perform any special processing on the beam itself or change the shape of its underside.

[0011] The beam is characterized by having an upper mounting member with an upward-facing U-shaped cross-section attached to its upper surface. This feature allows for the attachment of the upper end of optional components such as covers to the upper mounting member, or for the neat routing of wiring and other components within the upper mounting member, without altering the shape of the beam's upper surface.

[0012] The width of the support column is made larger than the width of the beam, and the width of the beam when the side mounting members are attached to both sides of the beam is made to be approximately equal to the width of the support column. This feature makes it possible to align the sides of the support column and the side mounting member almost flush with each other, improving the appearance. [Brief explanation of the drawing]

[0013] [Figure 1] This is a perspective view of a spatial structure according to an embodiment of the present invention. [Figure 2]This is an enlarged longitudinal cross-sectional view along line AA in Figure 1. [Figure 3] This is an enlarged cross-sectional view along line BB in Figure 1. [Modes for carrying out the invention]

[0014] Embodiments for implementing the spatial structure of the present invention will be described below based on examples. [Examples]

[0015] The movable partition device according to this embodiment will be described with reference to Figures 1 to 3. As shown in Figure 1, the spatial structure 1 of this embodiment is installed independently on the floor surface F in order to partition a large indoor space such as an office or exhibition hall into a rectangular shape.

[0016] The spatial structure 1 comprises four rectangular tubular support columns 2 arranged at predetermined intervals in the front, back, left, and right directions, with their lower ends supported by adjusters (not shown), which are height adjustment means, on the floor surface F; a beam 3 made of four rectangular tubes in the front, back, left, and right directions, connecting the upper ends of adjacent support columns 2 at right angles; two grid-like fixed panels 4a on the left and right, spaced apart from each other between the lower end of the front beam 3 and the floor surface F; four grid-like fixed panels 4a, spaced apart from each other between the lower end of the left beam 3 and the floor surface F; two grid-like fixed panels 4a, spaced apart from each other between the lower end of the right beam 3 and the floor surface F, such that an entrance is formed between the opposing surfaces; three plate-like fixed panels 4b, spaced between the lower end of the rear beam 3 and the floor surface F; and two grid-like sliding doors 5, 5, spaced between the outer surface of the beam 3 and the floor surface F, so as to be able to open and close an entrance (not shown) formed between the two front grid-like fixed panels 4a.

[0017] The lattice-shaped fixed panel 4a, the plate-shaped fixed panel 4b, and the sliding door 5 correspond to optional members. In this embodiment, the columns 2 and the beams 3 are formed in a square tube shape from steel, but they can also be formed by extrusion molding of an aluminum material. Further, the lattice-shaped fixed panel 4a can be changed to a plate-shaped fixed panel, the plate-shaped fixed panel 4b can be changed to a lattice-shaped fixed panel, and the lattice-shaped sliding door 5 can be changed to, for example, a plate-shaped panel or a glass panel.

[0018] As shown in FIG. 3, at the longitudinal ends of each beam 3, a U-shaped bracket 6 in plan view is fixed by welding, and by fixing this bracket 6 to the side surface of the upper end of the column 2 with bolts 7 and nuts 8, both ends of the beam 3 are fixed to the column 2. The bolt 7 can be inserted into the inside from an opening (not shown) formed on the upper surface of the side end of the beam 3, and the nut 8 can be inserted into the inside from the upper end opening of the column 2. The width of the column 2 is set to be larger than the width of the beam 3 by a predetermined dimension, so that the width when the side mounting members 9 and 16 described later are attached to both side surfaces of the front beam 3 is substantially equal to the width of the column 2. Further, when the front cover 24 and 26 described later are attached to both side surfaces of the beam 3, the side surfaces of the column 2 and the front cover 24 and 26 can be aligned on the same plane.

[0019] As shown in FIG. 2, on the side surface of the front side of the front beam 3, a side mounting member 9 having a length substantially equal to the left-right length of the beam 3 is attached so as to extend downward from the lower surface of the beam 3 and the upper end thereof is substantially aligned with the upper end surface of the beam 3. The extending portion of the side mounting member 9 that extends downward from the beam 3 serves as the mounting portion 91 for the left and right sliding doors 5. The side mounting member 9 is composed of two front and rear metal plates 92, 92, and is formed in a hollow shape by overlapping and welding the inward pieces 92a, 92a that are bent so as to face each other at the upper and lower edges thereof.

[0020] The side mounting member 9 is fixed to the beam 3 at a plurality of locations in the left - right direction as follows. That is, the screw 10 inserted through the opening 92b formed in the front - side metal plate 92 is screwed into the female screw hole 3a formed in the front wall of the beam 3 through the through - hole 92c formed in the rear - side metal plate 92, whereby the side mounting member 9 is attached to the side surface on the front - side of the beam 3.

[0021] On the side surface on the front - side of the mounting portion 91 of the side mounting member 9, a support frame 11 for supporting the upper end portion of the sliding door 5 is attached. The support frame 11 has a base body 111 having substantially the same length as the left - right length of the mounting portion 91, a cover member 112 having a downward U - shaped cross - section fixed along the left - right direction to the lower surface of the base body 111, and a rail member 113 having a substantially downward U - shaped cross - section continuously arranged in the left - right direction and fitted inside the cover member 112. In this embodiment, the cover member 112 is formed of a metal plate, and the rail member 113 is formed by extrusion molding of an aluminum material.

[0022] The base body 111 is configured by fixing the front and rear downward pieces 111b and 111e of the upper and lower two metal plates 111a and 111d having a substantially downward U - shaped cross - section to each other by welding or the like so as to have a space inside. The base body 111 is attached to the mounting portion 91 as follows. That is, a plurality of left - right bolts 12 are inserted into the base body 111 through the plurality of openings 111c formed in the lower metal plate 111a, each bolt 12 is inserted through the through - hole of the rear - side downward piece 111e of the upper - side metal plate 111d, and a plurality of locations in the longitudinal direction are fixed to the screw holes of the front - side metal plate 92 of the mounting portion 91, whereby the base body 111 is attached to the side surface on the front - side of the mounting portion 91 so as to protrude forward.

[0023] A plurality of locations in the left - right direction of the cover member 112 and the rail member 113 are fixed by bolts 113b inserted from below the rail member 113 to the lower surface of the lower - side metal plate 111a. On the upper surface of the upper - side metal plate 111d of the base body 111, a plurality of cover mounting members 114 having an upward U - shaped cross - section for fixing the lower end portion of the decorative cover 26 described later are fixed along the longitudinal direction.

[0024] At the lower end of the rail member 113, two inward-facing horizontal pieces 113a, 113a are arranged in opposition to each other. The upper surfaces of these inward-facing horizontal pieces 113a, 113a support a pair of front and rear rollers 13, 13 located at both ends of the upper part of the sliding door 5, thereby allowing them to move freely. The sliding door 5 is thus substantially suspended from the support frame 11. A downward-facing groove 14, which is continuous in the left-right direction, is formed on the lower surface of the sliding door 5. By slidably fitting this groove 14 into a guide rail 15 laid on the floor surface F, the sliding door 5 can be opened and closed stably in the left-right direction.

[0025] As shown in Figure 2, multiple side mounting members 16 for attaching the lower end of the exterior cover 24 (described later) are fixed to the rear side of the front beam 3 at predetermined intervals in the longitudinal direction by screws 17. The lower half of the side mounting member 16 has a bent portion 16a that bulges out to the rear, and an L-shaped locking portion 16b is integrally attached to the lower end of the bent portion 16a. The bent portion 16a extends below the lower surface of the beam 3, and its vertical dimension is approximately equal to the vertical dimension of the mounting portion 91 of the front side mounting member 9. Side mounting members 16 of this shape are attached to both sides of all beams 3 except the front beam 3 (see Figure 3). The space enclosed by the front side mounting member 9, the bent portion (extended portion) 16a of the rear side mounting member 16 and the lower surface of the beam 3 is the mounting space 18 for the upper end of the lattice-shaped fixing panel 4a, which is an optional member separate from the sliding door 5.

[0026] Within the mounting space 18, a lower mounting member 19 with a downward-facing U-shaped cross-section is fixed to the center of the lower surface of the beam 3 in the front-to-back direction by bolts 12B for attaching the upper end of the grid-like fixing panel 4a. The left-to-right dimensions of the lower mounting member 19 are equal to the left-to-right dimensions of the beam 3.

[0027] As shown in Figure 2, a grid-like fixing panel 4a is fixed between the lower mounting member 19 and the floor surface F in the following manner. At the opening edge of the lower end of the lower mounting member 19, inward-facing horizontal pieces 19a, 19a are arranged in opposition to each other. Furthermore, mounting rods 21, each having two clamping plates 20, 209 spaced vertically apart at their upper ends, are projected upward from both the left and right sides of the upper surface of the grid-like fixing panel 4a, and similarly, telescopic adjusters 22 are provided on both the left and right sides of the lower surface.

[0028] To fix the lattice-shaped fixing panel 4a, first, two clamping plates 20, 20 are inserted into the inward-facing horizontal pieces 19a, 19a of the lower mounting member 19, clamping the inward-facing horizontal pieces 19a, 19a from above and below. This insertion can be done from the side end of the lower mounting member 19 with one of the opposing support columns 2 removed. Next, by extending the telescopic adjuster 22 and pressing it against the floor surface F, the lattice-shaped fixing panel 4a can be fixed between the lower mounting member 19 and the floor surface F.

[0029] Multiple upper mounting members 23, each having an upward-facing U-shaped cross-section with a width greater than the width of the beam 3, are fixed to the upper surface of the beam 3 at predetermined intervals along the longitudinal direction by bolts 12C. A surface cover 24 is attached between the upper mounting members 23 and the side mounting members 16 along the longitudinal direction as follows: The upward-facing U-shaped portion 24a at the lower end of the surface cover 24 is fitted from below into the locking portion 16b of the side mounting member 16, and then the inward-facing bent piece 24b connected to the upper end of the surface cover 24 is fixed with screws 25 to the inward-facing bent piece 23a connected to the upper end of the rear side of the upper mounting member 23. The interior of the upper mounting members 23 can be used as a wiring space, etc. Surface covers 24 of this shape are attached to both sides of all beams 3 except the front beam 3 (see Figure 3). The upper mounting members 23 may be formed in a shape that is continuous along the longitudinal direction. Furthermore, a cushioning material 30 is provided between the side mounting member 16 and the outer cover 24 to prevent rattling.

[0030] An L-shaped cross-section covering cover 26 is attached to the front side of the front beam 3, covering the outer surface of the side mounting member 9 and the upper surface of the support frame 11, as follows: First, an inwardly bent piece 26a connected to the upper end of the covering cover 26 is fixed with screws 25 to an inwardly bent piece 23a connected to the upper end of the front side of the upper mounting member 23. Next, with the horizontal piece 26b at the lower end of the covering cover 26 supported by the upper edge of the cover mounting member 114 fixed to the upper surface of the support frame 11, a plurality of bolts 27 on the left and right are passed through the horizontal piece 26b and the cover mounting member 114 and screwed into female screw holes 28 formed on the upper surface of the support frame 11, thereby fixing the horizontal piece 26b to the upper surface of the support frame 11.

[0031] In the spatial structure 1 according to the embodiment, the beam 3 is formed from a square tube, and since its cross-sectional shape is extremely simple, not only can the beam 3 be manufactured inexpensively, but inexpensive, readily available steel square tubes can also be used as is, thus reducing the cost of the beam 3.

[0032] Furthermore, by making the extension portion of the side mounting member 9 that extends downward from the lower surface of the beam 3 into a mounting portion 91 for the optional sliding door 5, there is no need to perform any special processing on the beam 3 to attach the sliding door 5, and the sliding door 5 can be easily attached to the mounting portion 91 without interfering with the beam 3.

[0033] Furthermore, since the side mounting member 9 is formed in a hollow shape, it is possible to reduce the weight while ensuring the strength of the side mounting member 9. Moreover, since the upper end of the side mounting member 9 extends to the upper end of the beam 3, the mounting area of ​​the side mounting member 9 to the side of the beam 3 is increased, and the mounting strength of the side mounting member 9 can be increased.

[0034] Furthermore, a side mounting member 16 is attached to the rear side of the beam 3 so as to extend downward from the lower surface of the beam 3. The space enclosed by the extended portion of this side mounting member 16, the mounting portion 91 of the front side mounting member 9, and the lower surface of the beam 3 is used as the mounting space 18 for the optional lattice-shaped fixing panel 4a. This makes it possible to attach different optional members to this mounting space 18 and to the mounting portion 91 of the side mounting member 9 attached to the side of the beam 3, thereby increasing the range of optional members that can be used.

[0035] Furthermore, within the mounting space 18, a lower mounting member 19 with a downward-facing U-shaped cross-section is attached to the lower surface of the beam 3, to which the upper end of the lattice-shaped fixing panel 4a can be attached. Since the upper end of the lattice-shaped fixing panel 4a can be attached to the lower surface of the beam 3 via the lower mounting member 19, there is no need to perform any special processing on the beam 3 itself or change the shape of its lower surface.

[0036] Furthermore, since multiple upper mounting members 23 with an upward-facing U-shaped cross-section are attached to the upper surface of the beam 3 in the longitudinal direction, the upper end of the optional covering cover 24 can be attached to the upper mounting members 23, or wiring and other components can be housed inside the upper mounting members 23 for a neater appearance, without changing the shape of the upper surface of the beam 3.

[0037] Furthermore, by making the width of the support column 2 greater than the width of the beam 3, and by making the width when the side mounting members 9 and 16 are attached to both sides of the beam 3 approximately equal to the width of the support column 2, it becomes possible to align the sides of the support column 2 and the side mounting members 9 and 16 to be almost flush, improving the appearance.

[0038] Although embodiments of the present invention have been described above with reference to the drawings, the specific configurations are not limited to these embodiments, and additions and modifications that do not depart from the spirit of the present invention are also included.

[0039] For example, in the above embodiment, a hollow side mounting member 9 is used, but a flat side mounting member 9 with high strength can also be used.

[0040] Furthermore, in the above embodiment, for example, the sliding door 5 is attached to the mounting portion 91 of the side mounting member 9, but it is also possible to attach multiple optional members such as sliding panels.

[0041] Furthermore, for example, in the above embodiment, the upper end of the grid-shaped fixing panel 4a is attached to the lower mounting member 19. However, the upper end of an optional member such as a sliding panel can also be movably supported. [Explanation of symbols]
