Description

The present invention relates to a spatial structure that divides independent spaces.

Spatial structures that use multiple beams to divide independent spaces are used to create multi-purpose spaces in large indoor spaces such as offices, exhibition halls, hospitals, and schools. Known types of spatial structures include ceiling-suspended spatial structures that divide independent spaces using multiple beams suspended horizontally by hanging fixtures hanging from a structure, and erected spatial structures that divide independent spaces using multiple beams connecting multiple supports.

The spatial structure shown in Patent Document 1 has multiple pillars that stand upright from the floor, the upper ends of which are connected by horizontally extending beams. Partition panels can be attached to the areas of the spatial structure that are surrounded by adjacent pillars, the beams connecting them, and the floor, dividing the interior space into spaces of a specified size.

A groove that opens to the side is formed along the longitudinal direction on the side of each beam, and the grooves can be used to attach and detach connectors used to connect beams together, as well as various optional components such as shelves and panels.

Japanese Patent No. 6712854 (page 9, figure 8)

The spatial structure of Patent Document 1 has excellent scalability because the beams can be connected to each other and optional components can be attached at any position using the grooves extending in the longitudinal direction. In such a spatial structure of Patent Document 1, the beams are made of metal such as aluminum, but there are cases where the color of the beams does not match the color of the surrounding environment in which the spatial structure is installed, so there has been a demand to match the color of the beams to the color of the surrounding environment.

The present invention was made to address these problems, and aims to provide a spatial structure that can easily impart color to a beam.

In order to solve the above problems, the spatial structure of the present invention comprises:
A spatial structure in which a space is divided by a beam formed along a longitudinal direction of a C-shaped gutter having a C-shaped cross section that opens to the side,
It is characterized by having a cover member consisting of a decorative part extending in the longitudinal direction of the beam and covering the side of the beam, an attachment part provided on the back surface of the decorative part, extending in the longitudinal direction and having an engagement groove opening to the beam side, and a locking part that is fitted into the engagement groove of the attachment part and is detachably engaged with the C-shaped gutter.
According to this feature, the cover member can be removably attached to the side of the beam by engaging the engaging portion with an existing C-shaped gutter, so that by selecting the color of the decorative portion of the cover member, the side of the beam can easily be given a color that blends in with the surrounding environment.

The beam has a pair of opposing pieces extending toward each other from the upper and lower edges of the opening of the C-shaped gutter, and the engaging portion has claw portions that are engaged with the back surfaces of the pair of opposing pieces.
According to this feature, the claw portions of the locking portion are locked to the rear surfaces of the pair of opposing pieces that make up the C-shaped gutter, so that movement of the cover member in a direction away from the beam can be restricted.

The back surface of the decorative part is provided with an attachment part having an engagement groove extending in the longitudinal direction and opening to the beam side, and the locking part is arranged to be engaged with the engagement groove of the attachment part.
According to this feature, the locking portion can be fitted and positioned at any position in the longitudinal direction of the mounting portion, so that the locking portion can be positioned in a well-balanced manner relative to the decorative portions having different longitudinal lengths.

The mounting portion is formed of a single plate member, and upper and lower ends of the mounting portion are each bent toward the beam.
According to this feature, since the strength of the plate member constituting the mounting portion is increased, deformation of the decorative portion on which the mounting portion is disposed can be prevented even if an external force is applied to the beam side.

The decorative portion is formed from a single plate member, and the upper and lower ends of the decorative portion are each bent toward the beam.
According to this feature, the strength of the upper and lower ends of the decorative part is increased, so that deformation of the decorative part can be prevented even if an external force is applied to the upper and lower ends of the decorative part.

The side edge of the beam is provided with an upwardly rising upright piece, and the upper end of the decorative part is formed with a fitting portion that fits into the upper end of the upright piece from above.
According to this feature, the decorative part can be positioned vertically relative to the beam by fitting the fitting portion into the upper end of the standing piece.
[Preferred embodiment]

A counter comprising a plurality of columns and beams connected between the columns, the counter having a top plate attached to the beams of a space structure that divides a space, via brackets,
The bracket comprises a base which is fixed to the bottom or side wall of a groove which is formed along the longitudinal direction on the upper part of the beam and opens upward, and whose upper end is positioned above the opening of the groove, and a top plate support part which extends approximately horizontally from the upper end of the base to the side of the beam.
This allows the base of the bracket to be fitted into the groove, and the tabletop support portion extends approximately horizontally from the upper end of the base, past the upper end of the side wall of the groove and protruding out to the side of the beam, so that the height dimension of the tabletop support portion positioned below the tabletop can be reduced and the space below the tabletop can be used more widely.

The base includes a bottom portion fixed to the bottom portion of the groove, and a side portion extending upward from a side edge of the bottom portion along a side wall portion of the groove.
With this, the side of the bracket is positioned close to the side wall of the groove, making it easy to insert the bottom of the bracket into the bottom of the groove from above and fix it, and since the bracket is positioned along the bottom and side wall of the groove, most of the groove can be used as wiring space.

A C-shaped upper groove having a C-shaped cross section that opens upward is formed along the longitudinal direction at the bottom of the recessed groove, and the bottom plate portion is fixed to a mounting bracket that is placed in the C-shaped upper groove.
This allows the mounting bracket to be placed at any position in the longitudinal direction of the C-shaped upper groove, so that the position of the bracket relative to the beam can be freely changed.

The bottom is fixed to the mounting bracket by a bolt.
This allows the bracket to be easily and firmly fixed to the mounting fixture by the bolt.

The top plate is supported by each of the top plate supporting portions of a pair of brackets arranged in the width direction of the beam.
With this, the tabletop is supported at two points in the width direction of the beam by the pair of brackets, so that moments in opposite directions from each tabletop act on the bottom of the groove from the base of the pair of brackets, making the total moment acting on the beam small, and the tabletop can be stably supported. Also, since the pair of brackets can be fine-tuned separately and fixed to the beam, assembly precision is high.

The pair of brackets have recessed and protruding fitting portions that restrict relative movement between them in the horizontal direction.
According to this, the relative movement of the pair of brackets in the horizontal direction is restricted by the concave-convex fitting portions, so that the pair of brackets and the top plate can be accurately aligned.

A C-shaped gutter having a C-shaped cross section and opening laterally is formed along the longitudinal direction on the side surface of the beam,
A cover member is attached to the side of the beam and is composed of a decorative part extending in the longitudinal direction of the beam and covering the side of the beam, and a locking part provided on the back surface of the decorative part and lockingly attached to the C-shaped gutter.
With this, the cover member is attached to the side of the beam by engaging the engaging portion with the C-shaped gutter, so that the decorative portion of the cover member can easily give the side of the beam a color that blends in with the surrounding environment.

The top plate has a through groove formed therein that passes through in the vertical direction and communicates with the recessed groove.
This allows wiring to be led out from the recessed groove through the through hole onto the top plate.

A slide surface body device is attached to a beam of a spatial structure in which a space is divided by a plurality of beams having a C-shaped cross section and opening to the side along a longitudinal direction, the beams comprising:
A frame member extending in the longitudinal direction of the beam is fixed to the side surface of the beam via a mounting bracket disposed in the C-shaped gutter,
The frame material has a rail groove that opens downward and is formed along the longitudinal direction, and a slide surface body that is movable in the longitudinal direction is suspended in the rail groove.
With this, the frame material is fixed to the side of the beam using mounting brackets arranged in the C-shaped gutter, and the sliding surface body is suspended below the rail groove of the frame material, thereby suppressing the swaying of the sliding surface body relative to the beam.

The beam is provided with a pair of opposing pieces extending in a direction approaching each other from upper and lower edges of the opening of the C-shaped gutter,
The pair of opposing pieces are sandwiched between the mounting bracket and the frame material by a bolt being screwed into the mounting bracket.
With this, the pair of opposing pieces are sandwiched in the width direction between the mounting bracket and the frame material, so that the frame material can be firmly fixed to the beam.

The side of the beam located below the C-shaped gutter and the side of the frame material are in face-to-face contact.
With this, the side of the beam, which is located below the C-shaped gutter, and the side of the frame material are in face contact, so that rotation and twisting of the frame material relative to the beam is restricted and the frame material can be stably fixed to the beam.

The two C-shaped gutters are formed in the vertical direction on the side surface of the beam,
The frame material is fixed to the lower C-shaped gutter via the mounting bracket,
A cover member that covers the side surface of the beam is engaged with the upper C-shaped gutter,
The cover member extends downwardly to the frame member.
With this, the cover member can easily give the side of the beam a color that blends in with the surrounding environment, and since the cover member extends to the frame material, the beam is not exposed between the frame material and the cover member, resulting in an aesthetically pleasing appearance.

A slide surface body device attached to a beam of a spatial structure in which a space is divided by a plurality of beams having a C-shaped cross section that opens downward and a C-shaped lower groove formed along a longitudinal direction,
a base member disposed in the C-shaped lower groove; and a hanging member extending downward from the base member through an opening of the C-shaped lower groove,
Two rail members, which respectively suspend and support a slide planar body movable along the longitudinal direction of the beam, are supported by the hanging member on both sides in the width direction of the hanging member.
According to this, the pair of rail members and slide planar bodies can be aligned in the width direction and attached to the beam by utilizing the C-shaped groove as well as the base member and the hanging member.

The hanging member is provided with a pair of support parts extending outward from both sides in a width direction of the beam, and the support parts are provided to be movable in a vertical direction relative to the base member,
The two rail members are vertically sandwiched between the pair of support portions and the lower surface of the beam.
According to this, the two rail members can be sandwiched together between the pair of supports and the lower surface of the beam, so that the two rail members can be firmly and easily attached below the beam.

The beam has a pair of skirt plate portions extending downward from both sides thereof, and the two rail members are housed between the pair of skirt plate portions.
This provides an aesthetically pleasing design because the pair of foot plates prevent the two rail members from being exposed from the sides. In addition, the two rail members can be placed close to each other to form a sliding structure, and because they do not protrude beyond the beams to the sides, the design can be made compact.

The two rail members are in contact with the pair of bottom plate portions, respectively.
With this, the two rail members are each in contact with a pair of base plate portions, so that the rail members can be firmly fixed to the beam and the rail members can be prevented from falling between the pair of support portions and the underside of the beam.

The pair of support portions each have a support surface that slopes downward from the hanging member toward the outside in the width direction.
According to this, when the two rail members are sandwiched between a pair of support portions and the underside of the beam, each rail member is pressed against a pair of base plate portions by each support surface, allowing the two rail members to be firmly attached to the beam.

A C-shaped gutter with a C-shaped cross section that opens laterally is formed along the longitudinal direction on the side of the beam, and a cover member that covers the side of the beam is engaged with the C-shaped gutter, and the cover member extends downward to cover the base plate portion.
With this, the cover member can easily give the side of the beam a color that blends in with the surrounding environment, and since the cover member extends to the base plate portion, the base plate portion is not exposed from the side, resulting in an aesthetically pleasing appearance.

The following describes the implementation of the spatial structure according to the present invention based on the examples.

The spatial structure according to the first embodiment will be described with reference to Figs. 1 to 7. In the following description, the front side of the paper in Fig. 2 will be referred to as the front side (forward side) of the spatial structure, and the left and right sides as viewed from the front side will be referred to as the left and right sides of the spatial structure.

As shown in FIG. 1, the spatial structure 1 is installed to divide a large indoor space, such as an office, exhibition hall, hospital, or school, into a highly independent space, and is used, for example, as a meeting space.

The spatial structure 1 of this embodiment is mainly composed of multiple pillars 2 erected from the floor surface, multiple beams 3 extending horizontally to connect adjacent pillars 2, and a cover member 4 covering the side surface 3f (see Figure 2) of each beam 3. Additionally attached are fixed panels 5A, 5B attached using the beams 3 connecting adjacent pillars 2, and a counter device 6 installed using a beam (see Figure 6) connecting adjacent pillars 2 at a specified height. In this way, the beam 3 is not limited to connecting the upper ends of the pillars 2, but can be attached at any position in the height direction of the pillars 2.

First, we will explain the basic structure of the spatial structure 1.

As shown in Figure 1, the support pillar 2 is a vertically extending long member manufactured by extruding aluminum material, and extends from the floor surface to a position lower than the ceiling surface of the room. In other words, the upper end of the support pillar 2 and the ceiling surface are spaced apart in the vertical direction. It goes without saying that the upper end of the support pillar 2 may also abut the ceiling surface.

The beam 3 is a long, horizontally extending member made by extruding aluminum, with both longitudinal ends of the beam 3 connected to the opposing surfaces of adjacent columns 2.

As shown in FIG. 2, the beam 3 has standing pieces 3b, 3b that rise upward from both side edges. As a result, an upwardly facing groove 3A that opens upward is formed along the longitudinal direction at the top of the beam 3.

At the bottom 3a of the upward recessed groove 3A, a C-shaped upper groove 31 with a C-shaped cross section that opens upward is formed along the longitudinal direction of the beam 3. The beam 3 has a pair of opposing pieces 31b, 31b that extend in a direction approaching each other, i.e., in the width direction, from the upper edges of both side surfaces that make up the C-shaped upper groove 31, i.e., the left and right opposing surfaces 31a, 31a, and an opening 31c of the C-shaped upper groove 31 is formed between the opposing pieces 31b, 31b.

The beam 3 also has bottom plate portions 3d, 3d that hang down from both side edges. As a result, a downwardly facing groove 3B that opens downward is formed in the lower part of the beam 3 along the longitudinal direction. The lower ends 3e of the bottom plate portions 3d are also arranged to extend in directions that approach each other.

At the bottom 3c of the downward recessed groove 3B, a C-shaped lower groove 32 with a C-shaped cross section that opens downward is formed along the longitudinal direction. The beam 3 has a pair of opposing pieces 32b, 32b that extend in a direction approaching each other, i.e., in the width direction, from the lower end edges of both side surfaces that make up the C-shaped lower groove 32, i.e., the left and right opposing surfaces 32a, 32a, and an opening 32c of the C-shaped lower groove 32 is formed between the opposing pieces 32b, 32b.

On both sides 3f, 3f of the beam 3, two C-shaped gutters 33, 34 are provided, spaced apart in the vertical direction, each having a C-shaped cross section that opens to the side and extends in the longitudinal direction. In the following, the upper C-shaped gutter will be referred to as C-shaped gutter 33, and the lower C-shaped gutter will be referred to as C-shaped gutter 34.

The beam 3 has an upper and lower surface that constitutes the C-shaped gutter 33, i.e., a pair of opposing pieces 33b, 33b that extend in a direction approaching each other, i.e., in the vertical direction, from the opening side edges of the upper and lower opposing surfaces 33a, 33a, and an opening 33c is formed between the opposing pieces 33b, 33b. Note that the C-shaped gutter 34 has the same structure as the C-shaped gutter 33, so its description will be omitted.

The C-shaped upper groove 31, C-shaped lower groove 32, and C-shaped side grooves 33 and 34 of these beams 3 can be used as mounting grooves for mounting the fixing panels 5A and 5B described in detail later, and various optional components with functionality such as shelves and lighting.

The cover members 4 are attached to both side surfaces 3f, 3f of the beam 3. Note that since both cover members 4 have the same configuration, only one of the cover members 4 will be explained.

As shown in Figs. 2 and 3, the cover member 4 is mainly composed of a decorative member 41 as a decorative part that covers the entire side surface 3f of the beam 3, a C-shaped member 421 as an attachment part that is provided on the back surface of the decorative member 41 and has a fitting groove 42 that opens toward the beam 3 and extends in the longitudinal direction, a locking member 43 as a locking part that is fitted into the fitting groove 42, and a fitting part 44 that is provided along the upper end 41a of the decorative member 41 and fits from above onto the upper end of the standing piece part 3b of the beam 3. The C-shaped member 421 and the locking member 43 are the locking parts of the present invention.

The decorative member 41 is made of a single thin metal plate, and a sheet (not shown) (e.g., various wood-grain sheets) printed with colors and patterns that match the surrounding environment of the spatial structure 1 is attached to its surface. The upper end 41a and lower end 41b of this decorative member 41 are approximately L-shaped and are formed by bending from the surface base 41c of the decorative member 41, which extends vertically, to the beam 3 side. In other words, the upper end 41a and lower end 41b of the decorative member 41 have horizontal parts 411a, 411b that extend horizontally from the surface base 41c to the beam 3 side, and vertical parts 412a, 412b that extend perpendicularly from the end on the beam 3 side and face the surface base 41c.

The fitting groove 42 is composed of a C-shaped member 421 formed by bending a single metal plate member. The C-shaped member 421 has a vertical portion 421a extending along the surface base 41c of the decorative member 41, horizontal portions 421b, 421b extending parallel to the beam 3 side from the upper and lower ends of the vertical portion 421a, and opposing portions 421c, 421c extending vertically from the ends of the horizontal portions 421b, 421b in a direction approaching each other, and the portion between the opposing portions 421c, 421c forms the opening of the fitting groove 42.

The decorative member 41 and the C-shaped member 421 are open at their front-to-rear ends, i.e., their longitudinal ends.

The locking members 43 are made of synthetic resin molded products, and are arranged at appropriate intervals along the longitudinal direction of the C-shaped member 421 (only one locking member 43 is shown in FIG. 3). The locking member 43 is made up of a base portion 431 that is U-shaped when viewed from the front, extension portions 432, 432 that are generally L-shaped when viewed from the front and extend horizontally toward the rear beam 3 from both ends of the opening side of the base portion 431 in a direction approaching them, and claw portions 433, 433 that extend from the free ends of the extension portions 432, 432 in directions away from each other, i.e., in the vertical direction.

The surface 433a of each claw portion 433 facing the beam 3 is approximately parallel to the back surface 433b of the claw portion 433 facing the fitting groove 42. In addition, the claw portion 433 has an inclined surface 433c that tapers from the back surface 433b to the front surface 433a.

The locking member 43 is loosely inserted into the fitting groove 42 from one of the openings at the longitudinal end of the fitting groove 42 of the C-shaped member 421. When the locking member 43 is placed in the fitting groove 42, the base portion 431 is prevented from slipping out toward the beam 3 by the facing portion 421c extending up and down provided at the opening of the C-shaped member 421, and each extension portion 432 extends to the outside of the C-shaped member 421 through the opening of the fitting groove 42, and each claw portion 433, 433 is positioned closer to the beam 3 than the facing portion 421c of the C-shaped member 421. The number and position of the locking members 43 arranged in the longitudinal direction of the C-shaped member 421 can be freely changed. Furthermore, the locking members 43 are not limited to being arranged in multiple positions along the length of the C-shaped member 421. For example, as long as the claw portion 433 of the locking member 43 has a sufficient length along the length, one locking member 43 may be arranged for one C-shaped member 421.

The fitting portion 44 is configured to open downward and is made up of a vertical portion 412a of the upper end portion 41a of the decorative member 41 and an L-shaped member 441 fixed to the upper end portion 41a of the decorative member 41. The L-shaped member 441 has a horizontal portion 441a that extends along the upper surface of the horizontal portion 411a of the upper end portion 41a of the decorative member 41, and a vertical portion 441b that extends downward from the tip of the horizontal portion 441a.

The horizontal portion 441a of the L-shaped member 441 is fixed to the upper surface of the horizontal portion 411a of the decorative member 41 by welding or the like, and the vertical portion 441b of the L-shaped member 441 is positioned closer to the beam 3 than the vertical portion 441b of the decorative member 41.

To attach the cover member 4, as shown on the right side of the page in Figure 2, the fitting portion 44 of the cover member 4 is fitted from above into the upper end of the standing piece portion 3b, and the lower end of the cover member 4 is swung toward the beam 3 using the fitting portion 44 as a fulcrum, so that the locking member 43 is locked into the C-shaped gutter 33 of the beam 3, and the cover member 4 is attached to the beam 3.

To remove the cover member 4, (not shown) when the cover member 4 is attached to the beam 3, the cover member 4 is lifted upward until the fitting portion 44 is released from the upper end of the standing piece portion 3b, causing the upper extension portion 432 of the locking member 43 to elastically deform and disengaging the lower claw portion 433 from the C-shaped gutter 33. In this state, the cover member 4 can be tilted and pulled down diagonally to remove it from the beam 3.

In this way, the cover member 4 can be detachably attached to the side surface 3f of the beam 3 by engaging the engaging member 43 with the existing C-shaped gutter 33 provided on the beam 3, so that the decorative member 41 of the cover member 4 can cover the side surface 3f of the beam 3 and easily impart a color that blends in with the surrounding environment of the spatial structure 1.

When the cover member 4 is attached to the beam 3, the inclined surfaces 433c of each claw portion 433 of the locking member 43 come into contact with the edges of a pair of opposing pieces 33b, 33b that form the opening 33c of the C-shaped gutter 33, so that the inclined surfaces 433c function as a guide and the extensions 432, 432 elastically deform in directions approaching each other, making it easy to position each claw portion 433 within the C-shaped gutter 33.

When each claw portion 433 is placed in the C-shaped gutter 33, the claw portion 433 elastically returns to its original position, and the back surface 433b of each claw portion 433 engages with the back surface of each opposing piece 33b. This makes it possible to restrict the movement of the cover member 4 in the width direction away from the beam 3.

In addition, because the C-shaped member 421 extends along the longitudinal direction of the decorative member 41, the locking member 43 can be positioned at any position along the longitudinal direction of the C-shaped member 421. This allows the locking members 43 to be positioned in a well-balanced manner for various decorative members 41 with different longitudinal lengths. In other words, the decorative member 41 can be cut to fit various beams 3 with different longitudinal lengths, making it easy to manufacture the decorative member 41.

The locking member 43 is fitted into the C-shaped member 421 fixed to the back surface of the decorative member 41, so that the decorative member 41 and the locking member 43 are positioned vertically. When the cover member 4 is swung around the fitting portion 44 as a fulcrum during the work of attaching the cover member 4 to the beam 3, the locking member 43 is securely engaged with the C-shaped gutter 33.

The fitting groove 42 is formed by a C-shaped member 421, which is a single metal plate member, and the horizontal portions 421b, 421b located at the upper and lower ends of the C-shaped member 421 are bent toward the beam 3. This increases the strength of the C-shaped member 421, so that deformation of the decorative member 41 can be prevented even if an external force toward the beam 3 is applied to the portion of the decorative member 41 near where the C-shaped member 421 is attached. In addition, the opposing portions 421c, 421c are bent upward or downward to form an opening from the horizontal portions 421b, 421b, further increasing the strength of the C-shaped member 421.

In addition, the upper end 41a and the lower end 41b of the decorative member 41 are each bent toward the beam 3, so that the strength of the upper end 41a and the lower end 41b of the decorative member 41 is increased, and deformation of the decorative member 41 can be prevented even if an external force is applied to the upper end 41a and the lower end 41b of the decorative member 41.

In addition, the upper end 41a and lower end 41b of the decorative member 41 prevent the space between the decorative member 41 and the beam 3, in which the locking member 43 is arranged, from being exposed from above and below, improving the aesthetic appearance.

In addition, when the cover member 4 is attached to the beam 3, the upper and lower vertical portions 412a, 412b of the decorative member 41 are in contact with the standing piece portion 3b and the bottom plate portion 3d of the beam 3, so that the cover member 4 is prevented from swinging relative to the beam 3, and the attachment state of the cover member 4 is stable. Note that, when the cover member 4 is attached to the beam 3, the upper and lower vertical portions 412a, 412b of the decorative member 41 may be slightly spaced apart from the standing piece portion 3b and the bottom plate portion 3d of the beam 3.

In addition, a fitting portion 44 is provided on the upper end portion 41a of the cover member 4, and the fitting portion 44 is fitted from above into the standing piece portion 3b. This allows the top end surface of the cover member 4 and the top end surface of the beam 3 to be aligned vertically, allowing the cover member 4 to be accurately attached to the beam 3 and improving the appearance. In addition, since the fitting portion 44 is fitted from above into the standing piece portion 3b, the cover member 4 is less likely to come off the beam 3. Since the fitting portion 44 is fitted from above into the standing piece portion 3b and the lower end portion 41b abuts against the beam 3, the cover member 4 is even less likely to come off the beam 3.

Although the decorative portion is made of a metal plate, it may be made of wood, synthetic resin, or the like. Furthermore, although the present embodiment illustrates a form in which the locking portion is made of synthetic resin, it may be made of metal, or the like, and preferably it is sufficient that it is configured to be elastically deformable.

In addition, in this embodiment, the decorative part and the locking part are configured as separate members, but the decorative part and the locking part may be configured as one piece with the same member without providing a C-shaped member. Also, the locking part may be fixed to the decorative part by welding, etc.

In addition, in this embodiment, the fitting portion is formed by a decorative portion and an L-shaped member that is a separate member from the decorative portion, but these may be integrally formed from the same member as the decorative portion.

In addition, in this embodiment, an example is given of a configuration in which two C-shaped gutters, one above the other, are formed on the side of the beam, but this is not limited to this, and one or three or more C-shaped gutters may be formed on the side of the beam.

In addition, in this embodiment, an example is given in which the cover member is attached to the side of the beam by using the upper C-shaped gutter, but the cover member may also be attached to the side of the beam by using the lower C-shaped gutter.

Next, the fixed panels 5A and 5B will be described. As shown in Figures 1 and 4, the fixed panels 5A are lattice-shaped partition panels that separate the space inside the spatial structure 1 from the space outside the spatial structure 1. In this embodiment, two fixed panels are attached to both the left and right sides of the beam 3 on the front side of the spatial structure 1, and four are attached to the beam 3 on the rear side. That is, in the center of the front side of the spatial structure 1, there is formed an entrance 1A that is rectangular in front view and surrounded by the beam 3, the fixed panels 5A spaced apart on the left and right, and the floor surface. In addition, the entire rear side of the spatial structure 1 is partitioned by the fixed panel 5A.

The fixed panel 5A has a rectangular shape when viewed from the front, and at its upper end, multiple connecting fittings 51 that protrude upward are provided along the upper surface of the fixed panel 5A, and at its lower end, multiple expanding fittings 52 that protrude downward are provided along the lower surface of the fixed panel 5A.

The connecting fitting 51 is composed of a first member 511 having a square plate-shaped plate portion 511a arranged above the fixed panel 5A and extending on both sides along the longitudinal direction of the beam 3, a flat second member 512 extending in the longitudinal direction of the beam 3 and inserted into the C-shaped lower groove 32 of the beam 3, and a bolt 513 connecting the plate portion 511a of the first member 511 to the second member 512. The plate portion 511a of the first member 511 and the second member 512 are fastened together by the bolt 513, so that the opposing pieces 32b, 32b are sandwiched between the plate portion 511a of the first member 511 and the second member 512 in the vertical direction.

The expansion fitting 52 is capable of moving up and down relative to the fixed panel 5A, and by moving the expansion fitting 52 downward relative to the fixed panel 5A, a reaction force is received from the floor surface, and the plate portion 511a of the first member 511 is pressed against the bottom portion 3c of the downward groove 3B of the beam 3.

Returning to Figure 1, the fixed panel 5B is a rectangular plate-shaped panel that is shorter in vertical dimensions than the support posts 2, and is attached across both the front and back sides using the C-shaped gutters of multiple upper and lower beams (not shown) that extend parallel to each other at a position lower than the beams 3 that connect the upper ends of the support posts 2.

Next, the counter device 6 will be described with reference to Figures 5 to 7.

As shown in FIG. 5, the counter device 6 includes a beam 3 that is installed at a predetermined height between adjacent columns 2 in the spatial structure 1, a cover member 4 that covers both side surfaces 3f of the beam 3, a first bracket 61 and a second bracket 62 that serve as a pair of widthwise brackets fixed in multiple sets to the upper part of the beam 3, and a top plate 63 supported by the first bracket 61 and the second bracket 62. Note that the beam 3 and cover member 4 used in the counter device 6 have the same configuration as the beam 3 and cover member 4 used in the spatial structure 1 described above, and therefore a description thereof will be omitted.

As shown in Figures 6(a) and 7, the first bracket 61 is formed by bending a single metal plate, and includes a bottom plate portion 611 as the bottom of the bracket extending parallel to the bottom 3a of the upward groove 3A, a side plate portion 612 as the side of the bracket extending upward from the right edge of the bottom plate portion 611, and a top plate support portion 613 that projects in a horizontal plate shape from the upper edge of the side plate portion 612 in the opposite direction to the bottom plate portion 611. The bottom plate portion 611 and the side plate portion 612 form the base of the first bracket 61.

The front-to-rear width of the bottom plate portion 611 is shorter than the front-to-rear width of the side plate portion 612, and is provided in the front-to-rear center of the lower edge of the side plate portion 612. In addition, two through holes 611a are formed in the bottom plate portion 611 side by side in the front-to-rear direction.

In addition, in this embodiment, the tabletop support portion 613 has four long holes 613a extending in the front-rear direction. Specifically, two pairs of long holes 613a are formed in the front and rear, with two pairs aligned in the left-right direction.

As shown in Figures 6(b) and 7, the second bracket 62 is formed by bending a single metal plate, and includes bottom plate portions 621, 621 as the bottom portion of the bracket extending parallel to the bottom portion 3a of the upward groove 3A, a side plate portion 622 as the side portion of the bracket extending upward from the left edge of the bottom plate portions 621, 621, and a top plate support portion 623 that projects in a horizontal plate shape from the upper edge of the side plate portion 622 in the opposite direction to the bottom plate portion 621. The bottom plate portions 621, 621 and the side plate portion 622 form the base of the second bracket 62.

The bottom plate portions 621, 621 are disposed in front of and behind the lower edge of the side plate portion 622, which is a single plate-like portion, and a recess 624 having a concave shape when viewed from above is formed between the bottom plate portions 621, 621. In addition, each of the bottom plate portions 621, 621 has a through hole 621a formed therein.

In addition, in this embodiment, the tabletop support portion 623 has four long holes 623a extending in the front-rear direction. Specifically, two pairs of long holes 623a are formed in the front and rear, with two pairs of long holes 623a aligned in the left-right direction.

As shown in FIG. 6(c), the first bracket 61 and the second bracket 62 are configured to restrict their relative horizontal movement by fitting the bottom plate portion 611 of the first bracket 61 sideways into the recessed portion 624 of the second bracket 62. In other words, the bottom plate portion 611 of the first bracket 61 and the recessed portion 624 of the second bracket 62 function as a recess-recessed fitting portion that restricts their relative horizontal movement.

Returning to FIG. 5, the top plate 63 is a wooden board extending in the front-to-rear direction, and is formed with approximately the same front-to-rear length as the beam 3. In the center of the left-to-right direction of this top plate 63, multiple through holes 63a are formed in the front-to-rear direction, penetrating vertically.

As shown in FIG. 7, the first bracket 61 and the second bracket 62 are fixed to the beam 3 to which the cover member 4 is attached in a state in which the first bracket 61 and the second bracket 62 are fitted together (see also FIG. 6(c)). In more detail, the first bracket 61 and the second bracket 62 are fixed to the upper part of the beam 3 by inserting bolts 64 into the through holes 611a, 621a of the bottom plate portions 611, 621 and fastening them to plate-shaped mounting brackets 65 arranged in the C-shaped upper groove 31 of the beam 3.

When the first bracket 61 and the second bracket 62 are fixed to the beam 3, most of the bottom plate portion 611 and the side plate portion 612 that constitute the base of the first bracket 61, and most of the bottom plate portions 621, 621 and the side plate portion 622 that constitute the base of the second bracket 62 are accommodated in the upward groove 3A of the beam 3. The upper ends of the side plate portions 612, 622 are positioned above the opening of the upward groove 3A.

The side plate portions 612, 622 are disposed close to the standing pieces 3b, 3b and extend upward along the standing pieces 3b, 3b. The groove-shaped space S, which is open upward and surrounded by the bottom plate portions 611, 621 and the side plate portions 612, 612, is designed to allow wiring such as power lines for supplying electricity and signal lines for communication to pass through.

The top plate support parts 613, 623 extend horizontally along the upper surfaces of the standing pieces 3b, 3b. Specifically, the horizontal parts 441a constituting the fitting part 44 of the cover member 4 are sandwiched vertically between the top plate support parts 613, 623 and the standing pieces 3b, 3b.

The top plate 63 is disposed across the top plate support parts 613, 623 of the first bracket 61 and the second bracket 62, and is fixed to the top plate support parts 613, 623 using the long holes 613a, 623a and the bolts 66. At this time, each through hole 63a of the top plate 63 is connected to the groove-shaped space S.

As described above, the counter device 6 is attached to the spatial structure 1 that divides a predetermined space with a plurality of support columns 2 and a plurality of beams 3 that connect them. In the counter device 6 of this embodiment, the bases of the first bracket 61 and the second bracket 62 can be accommodated in the upward recessed groove 3A, and each tabletop support portion 613, 623 is configured to extend from the upper end of the side plate portion 612, 622 beyond the upper end of the standing piece portion 3b, 3b to the side of the beam 3 in a horizontal plate shape. This makes it possible to reduce the height dimension of the tabletop support portion 613, 623 arranged below the tabletop 63, and to widely use the space below the tabletop 63, especially the space at the corner between the tabletop 63 and the beam 3. Therefore, for example, the first bracket 61 and the second bracket 62 are prevented from contacting the feet of a seated person when the counter device 6 is in use, and the first bracket 61 and the second bracket 62 are difficult to see from the side of the counter device 6, improving the aesthetics.

In addition, since the top plate support parts 613, 623 are not positioned to the side of the side surface 3f of the beam 3, the cover member 4 can be attached using the C-shaped gutters 33, 34 of the beam 3, which makes it easy to give the side surface 3f of the beam 3 a color that blends in with the surrounding environment.

In addition, the horizontal portion 441a that constitutes the fitting portion 44 of the cover member 4 is sandwiched vertically between the top plate support portions 613, 623 and the vertical pieces 3b, 3b, so that the cover member 4 can be firmly attached to the beam 3.

The bases of the first bracket 61 and the second bracket 62 each include a bottom plate portion 611, 621 fixed to the upper surface of the beam 3, and a side plate portion 612, 622 extending upward from the side edge of the bottom plate portion 611, 621 along the standing piece portion 3b, 3b. The side plate portions 612, 622 are spaced apart in the width direction, and a groove-like space S surrounded by the bottom plate portions 611, 621 and the side plate portions 612, 612 is formed in the upward recessed groove 3A. This allows the bottom plate portions 611, 621 to be easily fixed from above the beam 3 using the groove-like space S, and the groove-like space S can be used as a wiring space.

In addition, because the bottom plate portions 611, 621 are fixed to the mounting brackets 65 that are placed in the C-shaped upper groove 31 provided on the top surface of the beam 3, the mounting brackets 65 can be placed at any position in the longitudinal direction of the C-shaped upper groove 31, so the positions of the first bracket 61 and the second bracket 62 relative to the beam 3 can be freely changed. For example, the first bracket 61 and the second bracket 62 can be appropriately placed in a position that provides balanced support for the top plate 63 or in a position that does not interfere with wiring.

The bottom plate portions 611, 621 are fixed to the mounting bracket 65 by bolts 64. As a result, the opposing pieces 31b, 31b that make up the C-shaped upper groove 31 are sandwiched vertically between the bottom plate portions 611, 621 and the mounting bracket 65, so that the first bracket 61 and the second bracket 62 can be firmly and easily fixed to the beam 3.

Moreover, the top plate 63 is supported by top plate support portions 613, 623 of a pair of a first bracket 61 and a second bracket 62 arranged in the width direction of the beam 3. With this, the top plate 63 is supported at two points in the width direction relative to the beam 3 by the first bracket 61 and the second bracket 62, so that a moment in the opposite direction from the top plate 63 acts from the bases of the first bracket 61 and the second bracket 62 to the bottom 3a of the upward recessed groove 3A, and the moment acting on the beam 3 as a whole is small, and the top plate 63 can be stably supported.
Furthermore, since the first bracket 61 and the second bracket 62 can be finely adjusted separately and fixed to the beam 3, it is easy to align the top board supports 613, 623 horizontally, and assembly precision is high.

In addition, the first bracket 61 and the second bracket 62 are restricted from moving horizontally relative to each other by fitting the bottom plate portion 611 of the first bracket 61 laterally into the recessed portion 624 of the second bracket 62, so that the first bracket 61 and the second bracket 62 can be accurately aligned with the top plate 63.

In addition, each through hole 63a of the top plate 63 is connected to the groove-shaped space S, so that the wiring in the groove-shaped space S can be brought out onto the top plate 63 through the through holes 63a, improving the functionality of the counter device 6.

The top plate 63 is formed with approximately the same front-to-rear length as the beam 3, so that the top plate 63 can cover the upward groove 3A of the beam 3 in the longitudinal direction, preventing the accumulation of dirt in the upward groove 3A and providing an aesthetically pleasing appearance.

In this embodiment, the base of the bracket is fixed to the bottom of the groove, but it may be fixed to the side wall of the groove.

In this embodiment, the base of the bracket is exemplified as being roughly L-shaped with a bottom plate and a side plate, but the shape can be freely changed as long as it is fixed to the bottom or side wall of the groove and its upper end is positioned above the opening of the groove.

In addition, in this embodiment, the bracket is made by bending a single metal plate, but this is not limited to this, and each part may be made of a separate material. The bracket may also be made of a material other than metal, such as synthetic resin.

Furthermore, the bracket is not limited to being attached to the beam using bolts and mounting hardware, but may also be attached to the beam by welding, for example.

In addition, in this embodiment, an example is given of a form in which the top plate is supported at both ends by each top plate support portion of a pair of brackets arranged in the width direction, but if a top plate is provided that extends only to the right or left from the beam, it may be supported at one end by a single bracket.
In addition, in this embodiment, a hat-shaped bracket with a tabletop support portion extending to the left and right is formed by a pair of brackets. However, the hat-shaped bracket may be formed by a single member.

The configuration of the concave-convex fitting parts of the pair of brackets may be freely changed. Furthermore, the configuration of the concave-convex fitting parts may be omitted. Furthermore, the pair of brackets may be attached at different positions in the longitudinal direction of the beam without being assembled in the width direction.

The material that makes up the tabletop is not limited to wood, and it may be made of metal, synthetic resin, etc. By preparing various tabletops and replacing them as appropriate according to changes in the surrounding environment, a counter device that blends in with the surrounding environment can be created.

Next, the spatial structure of Example 2 will be described with reference to Figures 8 to 10. Note that the description of the configuration that overlaps with the configuration shown in Example 1 will be omitted.

As shown in FIG. 8, the spatial structure 200 of this embodiment 2 is equipped with a slide panel device 7 as a slide surface body device instead of the counter device 6.

The sliding panel device 7 is mainly composed of a beam 3, cover members 4, 4' attached to the beam 3, a fixed panel 5A, a frame member 71 extending along the longitudinal direction of the beam 3 and attached to one side of the beam 3, and a sliding panel 73 as a sliding surface body suspended movably along a rail member 713 provided on the frame member 71. The beam 3, cover member 4, and fixed panel 5A used in the sliding panel device 7 are the same as those in the spatial structure 1 of the above-mentioned embodiment 1, so their description is omitted. Furthermore, as will be described in detail later, the cover member 4' has the same configuration as the cover member 4 except for the vertical dimensions. Also, the panel attached to the C-shaped lower groove 32 of the beam 3 (see Figure 2) may be a sliding panel instead of the fixed panel 5A.

Fixed panels 5A are arranged below the front and rear of the beam 3 that constitutes the sliding panel device 7. Two lattice-shaped sliding panels 73 are suspended from the frame material 71, and can be switched between a closed state (see FIG. 9(a)) in which the sliding panels 73 are brought close to each other to block the doorway 200A between the front and rear fixed panels 5A, and an open state (see FIG. 9(b)) in which the sliding panels 73 are moved away from each other to open the doorway 200A. For ease of explanation, the fixed panels 5A are not shown in FIG. 9.

As shown in FIG. 10, a frame member 71 is attached to the right side surface 3f of the beam 3. Specifically, the frame member 71 is attached via a plate-shaped mounting bracket 74 and a bolt 75 that are inserted into the lower C-shaped gutter 34 of the C-shaped gutters 33, 34 provided on the right side surface 3f of the beam 3.

The frame material 71 is composed of a base body 711 extending in the front-rear direction, a cover body 712 attached below the base body 711, and a rail member 713 fixed to the cover body 712.

The base body 711 is constructed by fixing a first member 714, which is formed by bending a single metal plate material and has a generally downward U-shape, and a second member 715, which is also generally downward U-shape, by a predetermined fixing method such as welding.

The first member 714 comprises a left side plate 714a that faces the right side surface 3f of the beam 3, an upper plate 714b that extends horizontally to the right from the upper end of the left side plate 714a, a right side plate 714c that extends vertically downward from the right end of the upper plate 714b, and a lower plate 714d that extends horizontally to the left from the lower end of the right side plate 714c. The space between the lower part of the left side plate 714a and the left part of the lower plate 714d is open downward, and an insertion hole 714e through which a bolt 75 can be inserted is formed in the left side plate 714a.

The second member 715 comprises a left side plate portion 715a extending vertically along the right surface of the left side plate portion 714a, an upper plate portion 715b extending horizontally to the right from the upper end of the left side plate portion 715a, and a right side plate portion 715c extending vertically downward from the right end of the upper plate portion 715b. The left side plate portion 715a of the second member 715 is fixed at a position lower than the insertion hole 714e in the left side plate portion 714a of the first member 714. The right side plate portion 715c of the second member 715 is fixed to the right side plate portion 714c with its lower end placed on the upper surface of the lower plate portion 714d of the first member 714.

The upper plate portion 715b of the second member 715 has a through hole 715d formed near the through hole 714e of the first member 714. This through hole 715d can be used to insert the bolt 75 into the through hole 714e and tighten the bolt 75 to the mounting bracket 74.

The cover body 712 is formed by bending a single metal plate material, and has a horizontal plate portion 712a that extends horizontally to the right from the side surface of the right foot plate portion 3d of the beam 3, and a U-shaped cover portion 712b that has a downward U-shaped groove that opens downward at the right end side of the horizontal plate portion 712a. The right side surface of the cover portion 712b is in contact with the lower plate portion 714d of the first member 714.

The rail member 713 is formed by bending a single metal plate into a downward U-shape, and horizontal pieces 713b are provided that extend toward each other from the lower ends of the left and right side plate portions 713a of the rail member 713, and rollers 73a provided on the upper part of the slide panel 73 can run on the upper surface of each horizontal piece 713b. In other words, the rail member 713 has a rail groove formed on its inside that opens downward.

The cover portion 712b of the cover body 712 can be fitted with the rail member 713 from below, and the bottom of the cover portion 712b and the bottom of the rail member 713 are fixed to the upper plate portion 715b of the second member 715 by bolts 76. The cover body 712 prevents the bolts 75 from being exposed from below, resulting in an aesthetically pleasing appearance.

As described above, the sliding panel device 7 has a frame member 71 attached to the lower part of the side surface 3f of the beam 3 via mounting brackets 74 and bolts 75, and the frame member 71 is provided with a rail member 713 that forms a rail groove that opens downward, and the sliding panel 73 is movably suspended from this rail member 713. In this way, since the sliding panel 73 is movably suspended from the rail member 713 of the frame member 71 that is fixed to the beam 3 using the C-shaped side groove 34 of the beam 3, it is possible to suppress the swinging of the sliding panel 73 relative to the beam 3.

In addition, a downward groove 73b extending in the front-to-rear direction is formed on the underside of the sliding panel 73, and this downward groove 73b is slidably fitted to a rail 77 laid on the floor surface, so that the fitting of the rail 77 with the downward groove 73b can suppress the swinging of the sliding panel 73.

In addition, by fastening the bolts 75 to the mounting brackets 74, the pair of upper and lower opposing pieces 34b that form the opening of the C-shaped gutter 34 are sandwiched in the width direction between the mounting brackets 74 and the frame material 71, so that the frame material 71 can be firmly fixed to the beam 3.

In addition, the left end of the left side plate 715a and the horizontal plate 712a of the frame material 71 face-contact the side surface 3f and the right side skirt plate 3d of the beam 3, so that rotation and twisting of the frame material 71 relative to the beam 3 is restricted and the frame material 71 can be stably fixed to the beam 3. In addition, the left end of the horizontal plate 712a of the cover body 712 contacts the side surface 3f of the beam 3, and the right side surface of the cover portion 712b contacts the lower plate 714d of the first member 714, so that the cover body 712 functions as a structural strength member for the frame material 71.

Furthermore, the frame material 71 is fixed to the lower C-shaped gutter 34 as one C-shaped gutter, and the cover member 4' is engaged with the upper C-shaped gutter 33 as the other C-shaped gutter, with the lower end of the cover member 4' extending to near the upper part of the frame material 71. This allows the cover member 4' to easily impart a color that blends in with the surrounding environment to the side surface 3f of the beam 3, and since the lower end of the cover member 4' extends to the frame material 71, the side surface 3f of the beam 3 is not exposed between the frame material 71 and the cover member 4', resulting in an aesthetically pleasing appearance.

The above-mentioned cover member 4 is attached to the left side surface 3f of the beam 3 to which the frame material 71 is not attached, and the left side surface 3f of the beam 3 can be decorated almost entirely. In this way, by preparing cover members 4, 4' with different vertical dimensions in advance, the beam 3 can be decorated according to whether or not the frame material 71 is present.

In this second embodiment, the frame material is made up of multiple members, but it may be made up of a single member. Also, the material that makes up the frame material can be freely changed.

In addition, in this embodiment 2, an example is given in which the frame material is attached to the lower C-shaped gutter of the two upper and lower C-shaped gutter structures, but the frame material may also be attached to the upper C-shaped gutter. In this case, a cover member can be attached to the lower part of the frame material using the lower C-shaped gutter.

Next, the spatial structure of Example 3 will be described with reference to Figures 11 to 14. Note that the description of the configuration that overlaps with the configuration shown in Example 1 will be omitted.

As shown in FIG. 11, the spatial structure 300 of this embodiment 3 has curtains 81 attached to the front at a distance from each other on the left and right. In addition, curtain devices 8 as sliding planar body devices are attached to the back and right side of the spatial structure 300. Note that only the curtain device 8 on the right side of the spatial structure 300 will be described below.

The curtain device 8 is mainly composed of a beam 3, a cover member 4 attached to the beam 3, and four curtains 81 suspended below the beam 3. The curtain 81 as a sliding surface body in this embodiment is a felt curtain with excellent soundproofing properties, and is in the form of a plate that does not stretch in the front-to-rear direction. The curtain may be an accordion-shaped curtain that can stretch in the front-to-rear direction. Furthermore, the beam 3 and cover member 4 used in the curtain device 8 have the same configuration as those in the spatial structure 1 of the above-mentioned embodiment 1, so a description thereof will be omitted.

Below the beam 3 constituting the curtain device 8, rail members 82 for movably suspending two curtains 81 are arranged in a line in the left-right direction (see Figure 13), and the state can be changed as appropriate to a closed state in which the entire right side of the spatial structure 300 is closed (see Figure 12(a)), a first open state in which an entrance/exit 300A is formed in the center of the right side of the spatial structure 300 (see Figure 12(b)), or a second open state in which the curtain 81 is moved to one side of the front or rear of the right side of the spatial structure 300, and an entrance/exit 300A is formed on the other side of the front or rear (see Figure 12(c)).

As shown in FIG. 13, the rail member 82 has a downward C-shape in cross section, and the curtain 81 is suspended movably by rollers 81a provided at the upper end of the curtain 81. The rail member 82 is attached to the lower part of the beam 3 in a line in the left-right direction using the C-shaped lower groove 32 of the beam 3 and a mounting bracket 83. The mounting bracket 83 is composed of a plate-shaped base member 831 loosely inserted into the C-shaped lower groove 32, a bolt 832 as a hanging member that extends downward from the base member 831 through the opening 32c of the C-shaped lower groove 32, and a plate-shaped support member 833 having a pair of support parts 833a that are inserted into the bolt 832 and extend from the bolt 832 to the left and right sides. The support member 833 is engaged with the head of the bolt 832 from below.

The left and right rail members 82 are supported by a pair of support parts 833a on both the left and right sides of the bolt 832. In this way, the pair of left and right rail members 82 can be easily attached to the beam 3 by lining them up in the left-right direction using the C-shaped lower groove 32 pre-installed in the bottom 3c of the downward groove 3B of the beam 3 and the mounting bracket 83.

In more detail, by fastening the bolt 832 to the base member 831, the support member 833 moves upward, and the left and right rail members 82 are sandwiched in the vertical direction between the pair of support parts 833a and the bottom 3c of the downward groove 3B. By fastening the bolt 832 to the base member 831, the left and right rail members 82 can be sandwiched together between the pair of support parts 833a and the bottom 3c of the downward groove 3B, so that the left and right rail members 82 can be firmly and easily attached below the beam 3.

The left and right rail members 82 are disposed in the downward groove 3B when attached to the beam 3. This provides an aesthetically pleasing appearance, as the left and right rail members 82 are not visible from the sides due to the pair of skirt plate portions 3d. The left and right rail members 82 can also be placed close to each other in the left-right direction to form a sliding structure, and because they do not protrude laterally beyond the beam, a compact structure can be achieved.

The left and right rail members 82 are in contact with a pair of bottom plate portions 3d. More specifically, the right rail member 82 has its left end portion supported by the support portion 833a at the lower end, and its right end portion side surface in contact with the right bottom plate portion 3d. The left rail member 82 has its right end portion supported by the support portion 833a at the lower end, and its left end portion side surface in contact with the left bottom plate portion 3d. This allows the rail member 82 to be firmly fixed to the beam 3, and prevents the rail member 82 from falling between the bottom plate portion 3d and the support portion 833a.

The pair of support parts 833a each have a support surface 833b that slopes downward from the bolt 832 toward the outside in the width direction. With this, when the bolt 832 is fastened to the base member 831, the left and right rail members 82 are pressed against the pair of skirt plate parts 3d by each support surface 833b, so that the rail members 82 can be firmly attached to the beam 3.

A cover member 4 is attached to the side surface 3f of the beam 3 using a C-shaped gutter 33, and this cover member 4 extends to the lower end of the skirt plate portion 3d. This allows the cover member 4 to easily impart a color that blends in with the surrounding environment to the side surface 3f of the beam 3, and because the cover member 4 extends to the skirt plate portion 3d, the skirt plate portion 3d is not exposed from the side, resulting in an aesthetically pleasing appearance.

Next, another form of curtain device will be explained using Figure 14.

As shown in FIG. 14, the curtain device 800 has six rail members 82 arranged in a row in the left-right direction below the beam 3. In more detail, two rail members 82, one on each side, are attached to the bottom of the beam 3 using the C-shaped lower groove 32 of the beam 3 and mounting brackets 83. Frame members 803 are attached to both the left and right sides of the beam 3 via mounting brackets 801 and bolts 802 that are placed in the left and right C-shaped side gutters 34, and two rail members 82, one on each side, are attached to the bottom of the frame members 803 using mounting brackets 804.

The frame material 803 has a downward U-shaped cross section and extends along the longitudinal direction of the beam 3. When the bolts 802 are fastened to the mounting brackets 801, the side plate portion 803a of the frame material 803 on the beam 3 side and the pair of upper and lower opposing pieces 34b that form the opening of the C-shaped gutter 34 are firmly attached by being clamped in the left-right direction between the heads of the bolts 802 and the mounting brackets 801.

In addition, the side plate portion 803a of the frame material 803 is in face contact with the bottom plate portion 3d below the C-shaped gutter 34, so that twisting of the frame material 803 relative to the beam 3 is restricted, and the frame material 803 can be stably fixed.

The mounting bracket 804 is composed of a base member 805 fixed to the horizontal plate portion 803c of the frame material 803, a bolt 806 fastened to the base member 805 from below, and a support member 807 having a pair of support portions 807a extending on both the left and right sides of the bolt 806. The rail member 82 is supported by the pair of support portions 807a on both the left and right sides of the bolt 806.

The rail member 82 is housed between the side plate portions 803a and 803b on both the left and right sides of the frame material 803, so it is not visible from the sides of the frame material 803 and has an excellent aesthetic appearance.

In addition, since the rail member 82 is in contact with the side plate portion 803a or the side plate portion 803b of the frame material 803, the rail member 82 is prevented from falling between the side plate portions 803a, 803b and the pair of support portions 807a.

The cover member 40 is attached to the side surface 3f of the beam 3 using the C-shaped gutter 33, and the cover member 40 extends to the frame material 803. This ensures that the side surface 3f of the beam 3 is not exposed between the frame material 803 and the cover member 40, resulting in an aesthetically pleasing appearance.

In this way, by attaching frame members 803 to the beam 3 as necessary, up to six rail members 82 can be arranged in the left-right direction. For example, if four rail members 82 are required in the left-right direction, one of the rail members 82 can be removed from the state shown in FIG. 14.

In this third embodiment, the supporting portion moves vertically together with the hanging member by fastening the hanging member to the base member, but the present invention is not limited to this. The supporting portion may move vertically relative to the hanging member by screwing a nut onto a threaded portion of the hanging member fixedly attached to the base member.

Furthermore, the rail member is not limited to being clamped between the underside of the beam and the support portion; for example, the rail member may be supported by being placed on the support portion.

In addition, in this embodiment 3, an example is given in which two rail members are housed between a pair of skirt plate portions, but the configuration of the pair of skirt plate portions may be omitted.

In addition, in this embodiment 3, an example is given in which the frame material is attached to the lower C-shaped gutter of the two upper and lower C-shaped gutter structures, but the frame material may also be attached to the upper C-shaped gutter. In this case, a cover member can be attached to the lower part of the frame material using the lower C-shaped gutter.

[Modification]
Next, a modified example of a fixed panel that is attached using a beam will be described with reference to FIG.

As shown in FIG. 15, the fixed panel 500 that constitutes part of the spatial structure of this modified example is composed of multiple upper and lower beams 3 that extend parallel to each other at a position lower than the beams 3 that connect the upper ends of the columns 2, a first board 501 that is attached across the left faces of the multiple upper and lower beams 3, a second board 502 that is attached across the right faces of the multiple upper and lower beams 3, and a shelf device 503 that is attached to the lower part of the lower beam 3.

The first board 501 is a whiteboard and includes a front surface member 501a on which characters, figures, etc. can be written, and a back surface member 501b attached to the back surface of the front surface member 501a. The back surface member 501b is provided with a locking portion 501c that can be locked to each of the C-shaped gutters 34 of the upper and lower beams 3. When the back surface member 501b is attached to the beams 3, the back surface member 501b is in face-to-face contact with the side surface 3f of each beam 3.

The second board 502 comprises a front surface member 502a decorated with felt or the like, and a back surface member 502b attached to the back surface of the front surface member 502a, and the back surface member 502b is provided with locking portions 502c that can be locked to the C-shaped gutters 34 of the upper and lower beams 3. When the back surface member 502b is attached to the beams 3, the back surface member 502b abuts against the side surface 3f of each beam 3. In addition, documents and the like can be attached to the front surface member 502a with pins or the like.

The shelf device 503 includes a plate-shaped mounting bracket 503a that is placed in the C-shaped lower groove 32 of the beam 3, a bolt 503b that extends downward from the mounting bracket 503a through the opening 32c of the C-shaped lower groove 32, a plate-shaped body 503c that extends to both the left and right sides from the lower end of the bolt 503b, and a cylindrical spacer 503d that surrounds the outer periphery of the bolt 503b. The plate-shaped body 503c is designed to accommodate pens and other accessories.

By fastening the bolt 503b to the mounting bracket 503a, the spacer 503d is clamped vertically between the bottom 3c of the downward recessed groove 3B and the plate-like body 503c, and the pair of opposing pieces 32b that form the opening 32c of the C-shaped lower groove 32 are clamped vertically by the mounting bracket 503a and the spacer 503d, so that the shelf device 503 can be firmly attached to the beam 3.

In addition, the shelf device 503 can be accessed from both the left and right sides, i.e., from the first board 501 and second board 502 sides, so that equipment can be taken in and out of the shelf device 503 from the first board 501 and second board 502 sides.

Although the embodiments of the present invention have been described above with reference to the drawings, the specific configuration is not limited to these embodiments, and the present invention also includes modifications and additions that do not deviate from the gist of the present invention.
