Description

[Technical field]

[0001] The present invention relates to a slide planar body device. [Background technology]

[0002] Spatial structures that divide independent spaces with multiple beams are used to divide multi-purpose spaces in large indoor spaces such as offices, exhibition halls, hospitals, schools, etc. Known types of such spatial structures include ceiling-suspended spatial structures that divide independent spaces with multiple beams suspended horizontally by suspenders hanging from a building frame, and standing spatial structures that divide independent spaces with multiple beams connecting multiple supports.

[0003] The spatial structure shown in Patent Document 1 has multiple pillars standing upright from the floor surface, the upper ends of which are connected by horizontally extending beams. Partition panels can be attached to the areas of the spatial structure surrounded by adjacent pillars, the beams connecting them, and the floor surface, dividing the interior space into spaces of a specified size.

[0004] A groove that opens laterally is formed along the longitudinal direction on the side of each beam, and the grooves allow the attachment and detachment of connecting devices used to connect the beams together, as well as various optional components such as shelves and panels.

[0005] [Patent Document 1] Patent No. 6712854 (page 9, figure 8) Summary of the Invention [Problem to be solved by the invention]

[0006] The spatial structure of Patent Document 1 has excellent scalability because the beams can be connected to each other and optional members can be attached at any position by 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 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.

[0007] The present invention has been made in response to such problems, and aims to provide a slide surface body device in which a pair of rail members and a slide surface body can be aligned in the width direction and attached to a beam. [Preferred embodiment] [Means for solving the problem]

[0008] 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, and a locking part provided on the back surface of the decorative part and capable of being 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.

[0009] The beam is provided with 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 is characterized by having 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 form the C-shaped gutter, so that movement of the cover member in a direction away from the beam can be restricted.

[0010] 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 decorative portions having different longitudinal lengths.

[0011] The mounting portion is formed from a single plate member, and upper and lower ends of the mounting portion are each bent towards 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.

[0012] 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.

[0013] 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]

[0014] A counter comprising a plurality of columns and beams connected between the columns, the beams being a space structure that divides a space, and a top plate being attached to the beams 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.

[0015] 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.

[0016] 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.

[0017] 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.

[0018] 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 the moment acting on the beam as a whole is small because the moment from each tabletop acts in the opposite direction from the base of the pair of brackets to the bottom of the groove, and the tabletop can be stably supported. Also, the pair of brackets can be fine-tuned separately and fixed to the beam, so assembly precision is high.

[0019] 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.

[0020] A C-shaped gutter having a C-shaped cross section that opens 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.

[0021] 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.

[0022] 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, A frame member extending in the longitudinal direction of the beam is fixed to the side 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.

[0023] 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.

[0024] 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-to-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.

[0025] 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.

[0026] In order to solve the above problems, the slide surface body device of the present invention is A horizontally extending elongated member; and A C-shaped groove with a C-shaped cross section that opens downward is formed along the longitudinal direction. Tabi Mounted on the frame , to divide the interior space A slide surface body device comprising: A base member is disposed in the C-shaped lower groove, and a hanging member extends downward from the base member through an opening of the C-shaped lower groove, A movable member along the longitudinal direction of the beam. A pair The slide planar bodies are each suspended and supported. Cross section: downward C-shaped Two rail members are supported by the hanging member on both sides in the width direction of the hanging member. And, The hanging member has a bolt and a pair of support parts that protrude from the bolt on both sides in the width direction of the beam, and when the bolt is fastened to the base member, the two rail members are sandwiched in the vertical direction between the pair of support parts and the lower surface of the beam. There are. 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, the base member and the hanging member.

[0027] The hanging member is provided with a pair of support portions extending outward from both sides in a width direction of the beam, and the support portions 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.

[0028] The beam has two ends. edge downwards from Forms a downward-facing groove that hangs down and opens downward. A pair of skirt plate portions are provided. The downward groove The two rail members are housed in the This has an aesthetic appeal 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 laterally beyond the beam, a compact structure can be achieved.

[0029] The two rail members are The left end side surface of the rail member on the left side in the width direction and the right end side surface of the rail member on the right side in the width direction The pair of bottom plate portions are in contact with each other. With this, the two rail members are each in contact with a pair of base plate portions, thereby enabling the rail members to be firmly fixed to the beam and preventing the rail members from falling between the pair of support portions and the underside of the beam.

[0030] The pair of support parts bolt slants downwards from the outside in the width direction and supports the lower sides of the two rail members. Each of the support surfaces has a The support surface extends beyond the support surface to both sides in the width direction. do. 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.

[0031] 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.

[0033] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment for carrying out a slide planar body device according to the present invention will be described below with reference to the accompanying drawings. EXAMPLES

[0034] A spacial structure according to a first embodiment will be described with reference to Fig. 1 to Fig. 7. In the following description, the front side of the paper in Fig. 2 is the front side (front side) of the spacial structure, and the left and right sides as viewed from the front side are the left and right sides of the spacial structure.

[0035] 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.

[0036] The spatial structure 1 of this embodiment is mainly composed of a plurality of columns 2 erected from the floor surface, a plurality of beams 3 extending horizontally and connecting adjacent columns 2, and a cover member 4 covering the side surface 3f (see FIG. 2) of each beam 3, and is additionally equipped with fixed panels 5A, 5B attached using the beams 3 connecting adjacent columns 2, and a counter device 6 installed using a beam (see FIG. 6) connecting adjacent columns 2 at a predetermined height position. In this way, the beam 3 is not limited to connecting the upper ends of the columns 2, but can be attached at any position in the height direction of the columns 2.

[0037] First, the basic structure of the spatial structure 1 will be described.

[0038] As shown in Fig. 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 be in contact with the ceiling surface.

[0039] The beam 3 is a long member extending horizontally and manufactured by extruding aluminum material, and both ends of the beam 3 in the longitudinal direction are connected to the opposing surfaces of adjacent columns 2.

[0040] 2, the beam 3 is provided with standing pieces 3b, 3b that stand upward from both side edges thereof. As a result, an upwardly facing recessed groove 3A that opens upward is formed in the upper part of the beam 3 along the longitudinal direction.

[0041] At the bottom 3a of the upward recessed groove 3A, a C-shaped upper groove 31 having 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 directions approaching each other, i.e., in the width direction, from the upper edges of both side surfaces that constitute 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.

[0042] The beam 3 is provided with bottom plate portions 3d, 3d that hang down from both side edges. As a result, a downwardly facing recessed groove 3B that opens downward is formed along the longitudinal direction in the lower part of the beam 3. The bottom ends 3e of the bottom plate portions 3d are provided so as to extend in directions approaching each other.

[0043] At the bottom 3c of the downward recessed groove 3B, a C-shaped lower groove 32 having a C-shaped cross section that opens downward is formed along the longitudinal direction. The beam 3 has a pair of opposed pieces 32b, 32b extending in a direction approaching each other, i.e., in the width direction, from the lower end edges of both side surfaces constituting the C-shaped lower groove 32, i.e., the left and right opposed surfaces 32a, 32a, and an opening 32c of the C-shaped lower groove 32 is formed between the opposed pieces 32b, 32b.

[0044] Two C-shaped gutters 33, 34, each having a C-shaped cross section that opens laterally and extends in the longitudinal direction, are provided spaced apart in the vertical direction on both side surfaces 3f, 3f of the beam 3. In the following, the upper C-shaped gutter will be referred to as the C-shaped gutter 33, and the lower C-shaped gutter will be referred to as the C-shaped gutter 34.

[0045] The beam 3 has a pair of opposed pieces 33b, 33b that extend in a direction approaching each other, i.e., in the vertical direction, from the upper and lower surfaces that constitute the C-shaped gutter 33, that is, the opening side edges of the upper and lower opposed surfaces 33a, 33a, and an opening 33c is formed between the opposed pieces 33b, 33b. Note that the C-shaped gutter 34 has the same configuration as the C-shaped gutter 33, so its description will be omitted.

[0046] The C-shaped upper groove 31, C-shaped lower groove 32, and C-shaped side grooves 33, 34 of these beams 3 can be used as mounting grooves for attaching the fixed panels 5A, 5B, which will be described in detail later, and various optional components with functionality such as shelves and lighting.

[0047] The cover members 4 are attached to both side surfaces 3f, 3f of the beam 3. Since both cover members 4 have the same configuration, only one of the cover members 4 will be explained.

[0048] 2 and 3, the cover member 4 is mainly composed of a decorative member 41 as a decorative part covering the entire surface of the side surface 3f of the beam 3, a C-shaped member 421 as a mounting part provided on the back surface of the decorative member 41 and having 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 part of the present invention.

[0049] The decorative member 41 is made of one thin metal plate, and a sheet (not shown) (e.g., various wood-grain sheets) printed with colors and patterns matching the surrounding environment of the spatial structure 1 is attached to the surface of the decorative member 41. The upper end 41a and the lower end 41b of the decorative member 41 are substantially L-shaped, and are formed by bending from a surface base 41c of the decorative member 41 extending vertically toward the beam 3 side. That is, the upper end 41a and the lower end 41b of the decorative member 41 have horizontal parts 411a, 411b extending horizontally from the surface base 41c toward the beam 3 side, and vertical parts 412a, 412b extending vertically perpendicularly from the end on the beam 3 side and facing the surface base 41c.

[0050] 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 includes 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. The opening of the fitting groove 42 is between the opposing portions 421c, 421c.

[0051] The decorative member 41 and the C-shaped member 421 have openings at their front and rear ends, i.e., at their longitudinal ends.

[0052] The locking members 43 are made of a synthetic resin molded product, and are arranged in a plurality at appropriate intervals in 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 from both ends of the opening side of the base portion 431 in a direction approaching the base portion 431 and horizontally toward the rear beam 3, 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 up-down direction.

[0053] A surface 433a of each claw portion 433 on the beam 3 side is approximately parallel to a back surface 433b of the claw portion 433 on the fitting groove 42 side. Also, the claw portion 433 has an inclined surface 433c tapering from the back surface 433b to the front surface 433a.

[0054] The locking member 43 is adapted to be loosely inserted into the fitting groove 42 from any of the openings at the longitudinal ends of the fitting groove 42 of the C-shaped member 421. When the locking member 43 is disposed in the fitting groove 42, the base portion 431 is prevented from slipping out toward the beam 3 by the facing portions 421c extending vertically and 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 of the claw portions 433, 433 is disposed on the beam 3 side relative to the facing portions 421c of the C-shaped member 421. The number and positions at which the locking members 43 are disposed 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 longitudinal direction of the C-shaped member 421. For example, one locking member 43 may be arranged for one C-shaped member 421 as long as the claw portion 433 of the locking member 43 has a sufficient length in the longitudinal direction.

[0055] 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 extending 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 extending downward from the tip of the horizontal portion 441a.

[0056] 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 away from the vertical portion 441b of the decorative member 41 toward the beam 3.

[0057] 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, whereby the locking member 43 is engaged with the C-shaped gutter 33 of the beam 3 and the cover member 4 is attached to the beam 3.

[0058] In addition, to remove the cover member 4, although 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 comes off the upper end of the standing piece portion 3b, whereby the upper extension portion 432 of the locking member 43 is elastically deformed and the engagement between the lower claw portion 433 and the C-shaped gutter 33 is released. In this state, the cover member 4 can be tilted and pulled diagonally downward to remove it from the beam 3.

[0059] In this way, the cover member 4 can be removably 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 side surface 3f of the beam 3 can be covered with the decorative member 41 of the cover member 4, thereby easily imparting a color that harmonizes with the surrounding environment of the spatial structure 1.

[0060] In addition, when attaching the cover member 4 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 constitute the opening 33c of the C-shaped gutter 33, so that the inclined surfaces 433c function as a guide and the extension portions 432, 432 elastically deform in directions approaching each other, making it easy to position each claw portion 433 within the C-shaped gutter 33.

[0061] In addition, when each of the claws 433 is disposed in the C-shaped gutter 33, each of the claws 433 elastically returns to its original position, and the back surface 433b of each of the claws 433 is engaged with the back surface of each of the opposing pieces 33b. This makes it possible to restrict the movement of the cover member 4 in the direction away from the beam 3 in the width direction.

[0062] In addition, since the C-shaped member 421 extends along the longitudinal direction of the decorative member 41, the locking member 43 can be arranged at any position in the longitudinal direction of the C-shaped member 421. This allows the locking members 43 to be arranged in a well-balanced manner for various decorative members 41 having different longitudinal lengths. In other words, the decorative member 41 can be cut to fit the length of various beams 3 having different longitudinal lengths, making it easy to manufacture the decorative member 41.

[0063] In addition, 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 in the vertical direction. 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.

[0064] Furthermore, fitting groove 42 is formed by C-shaped member 421, which is a single metal plate member, and horizontal portions 421b, 421b located at the upper and lower ends of C-shaped member 421 are bent toward beam 3. This increases the strength of C-shaped member 421, so that deformation of decorative member 41 can be prevented even if an external force toward beam 3 is applied to a portion of decorative member 41 near where C-shaped member 421 is attached. Furthermore, opposing portions 421c, 421c are bent upward or downward to form an opening from horizontal portions 421b, 421b, further increasing the strength of C-shaped member 421.

[0065] In addition, the upper end 41a and the lower end 41b of the decorative member 41 are each bent toward the beam 3, thereby increasing the strength of the upper end 41a and the lower end 41b of the decorative member 41, and preventing deformation of the decorative member 41 even if an external force is applied to the upper end 41a and the lower end 41b of the decorative member 41.

[0066] Furthermore, 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, thereby improving the aesthetic appearance.

[0067] Furthermore, 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 base plate portion 3d of the beam 3, preventing the cover member 4 from swinging relative to the beam 3 and stabilizing the attachment state of the cover member 4. 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 from the standing piece portion 3b and the base plate portion 3d of the beam 3.

[0068] Furthermore, a fitting portion 44 is provided on the upper end portion 41a of the cover member 4, and the fitting portion 44 is fitted into the standing piece portion 3b from above. This allows the upper end surface of the cover member 4 and the upper end surface of the beam 3 to be aligned in the vertical position, allowing the cover member 4 to be accurately attached to the beam 3, improving the appearance. Furthermore, since the fitting portion 44 is fitted into the standing piece portion 3b from above, the cover member 4 is less likely to come off the beam 3. Since the fitting portion 44 is fitted into the standing piece portion 3b from above 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.

[0069] Although the decorative portion is made of a metal plate, it may be made of wood, synthetic resin, etc. Furthermore, although the present embodiment illustrates an example in which the locking portion is made of synthetic resin, it may be made of metal, etc., and preferably, it is sufficient that the locking portion is made elastically deformable.

[0070] In addition, in the present 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 body using the same member without providing a C-shaped member, for example. Also, the locking part may be fixed to the decorative part by welding or the like.

[0071] In addition, in this embodiment, a form in which the fitting portion is formed by a decorative portion and an L-shaped member that is a separate member from the decorative portion has been exemplified, but these may also be formed integrally from the same member as the decorative portion.

[0072] In addition, in this embodiment, an example is given of a form in which two C-shaped gutters, one on the top and one on the bottom, 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.

[0073] In addition, in this embodiment, an example is given of a form in which the cover member is attached to the side of the beam by utilizing the upper C-shaped gutter, but the cover member may also be attached to the side of the beam by utilizing the lower C-shaped gutter.

[0074] Next, the fixed panels 5A and 5B will be described. As shown in Fig. 1 and Fig. 4, the fixed panel 5A is a lattice-shaped partition panel that separates 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 fixed panels 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 is surrounded by the beam 3, the fixed panels 5A arranged spaced apart on the left and right, and the floor surface. Also, the rear side of the spatial structure 1 is entirely partitioned by the fixed panel 5A.

[0075] The fixed panel 5A has a rectangular shape when viewed from the front, and at its upper end, a plurality of connecting fittings 51 protruding upward are provided along the upper surface of the fixed panel 5A, and at its lower end, a plurality of expansion fittings 52 protruding downward are provided along the lower surface of the fixed panel 5A.

[0076] The connecting fitting 51 is composed of a first member 511 arranged above the fixed panel 5A and having a square plate-shaped plate portion 511a extending on both sides along the longitudinal direction of the beam 3, a flat plate-shaped 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 facing pieces 32b, 32b are sandwiched between the plate portion 511a of the first member 511 and the second member 512 in the vertical direction.

[0077] The expandable fitting 52 is capable of moving vertically relative to the fixed panel 5A, and by moving the expandable 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 3c of the downward groove 3B of the beam 3.

[0078] Returning to Figure 1, the fixed panel 5B is a rectangular plate-shaped panel whose vertical dimensions are shorter than the support pillars 2, and is attached across its front and back surfaces 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 pillars 2.

[0079] Next, the counter device 6 will be described with reference to FIGS.

[0080] 5, the counter device 6 includes a beam 3 installed at a predetermined height between adjacent columns 2 in the spatial structure 1, a cover member 4 covering both side surfaces 3f of the beam 3, a first bracket 61 and a second bracket 62 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 the cover member 4 used in the counter device 6 have the same configuration as the beam 3 and the cover member 4 used in the spatial structure 1 described above, and therefore a description thereof will be omitted.

[0081] 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 portion of the bracket extending parallel to the bottom portion 3a of the upward recessed groove 3A, a side plate portion 612 as the side portion 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.

[0082] 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.

[0083] In this embodiment, four long holes 613a extending in the front-rear direction are formed in the top board support portion 613. Specifically, two pairs of long holes 613a arranged side by side in the left-right direction are formed in the front and back.

[0084] 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 recessed 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.

[0085] The bottom plate portions 621, 621 are disposed in front of and behind the lower edge of a single plate-like side plate portion 622, and a recess 624 having a recessed shape in top view is formed between the bottom plate portions 621, 621. Further, each of the bottom plate portions 621, 621 has a through hole 621a formed therein.

[0086] In this embodiment, four long holes 623a extending in the front-rear direction are formed in the top board support portion 623. Specifically, two pairs of long holes 623a arranged side by side in the left-right direction are formed in the front and rear.

[0087] 6(c), the first bracket 61 and the second bracket 62 are adapted to restrict relative horizontal movement therebetween by laterally fitting the bottom plate portion 611 of the first bracket 61 into the recessed portion 624 of the second bracket 62. That is, the bottom plate portion 611 of the first bracket 61 and the recessed portion 624 of the second bracket 62 function as a concave-convex fitting portion that restricts relative horizontal movement therebetween.

[0088] 5, the top plate 63 is a wooden board extending in the front-rear direction, and is formed to have approximately the same front-rear length as the beam 3. A plurality of through holes 63a are formed in the front-rear direction at the center in the left-right direction of the top plate 63, penetrating vertically.

[0089] 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 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 a plate-shaped mounting bracket 65 arranged in the C-shaped upper groove 31 of the beam 3.

[0090] 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 constituting the base of the first bracket 61, and most of the bottom plate portions 621, 621 and the side plate portion 622 constituting the base of the second bracket 62 are housed in the upward recessed groove 3A of the beam 3. The upper ends of the side plate portions 612, 622 are disposed above the opening of the upward recessed groove 3A.

[0091] The side plate portions 612, 622 are disposed close to the standing pieces 3b, 3b and extend upward along the standing pieces 3b, 3b. A groove-like space S that is surrounded by the bottom plate portions 611, 621 and the side plate portions 612, 612 and opens upward is designed to allow wiring such as power lines for supplying electricity and signal lines for communication to pass through.

[0092] 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.

[0093] The top plate 63 is disposed across the top plate support portions 613, 623 of the first bracket 61 and the second bracket 62, and is fixed to the top plate support portions 613, 623 by utilizing 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.

[0094] 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 the support columns 2. 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 extends 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 makes it possible 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 used, and the first bracket 61 and the second bracket 62 are difficult to see from the side of the counter device 6, improving the aesthetic appearance.

[0095] Furthermore, since the tabletop 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 by utilizing the C-shaped gutters 33, 34 of the beam 3, thereby easily imparting a color to the side surface 3f of the beam 3 that blends in with the surrounding environment.

[0096] Furthermore, the horizontal portion 441a constituting the fitting portion 44 of the cover member 4 is sandwiched vertically between the top board support portions 613, 623 and the standing pieces 3b, 3b, so that the cover member 4 can be firmly attached to the beam 3.

[0097] 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 portions 3b, 3b, and are spaced apart from the side plate portions 612, 622 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 by utilizing the groove-like space S, and the groove-like space S can be used as a wiring space.

[0098] Furthermore, because the bottom plate portions 611, 621 are fixed to the mounting bracket 65 arranged in the C-shaped upper groove 31 provided on the upper surface of the beam 3, the mounting bracket 65 can be arranged at any position in the longitudinal direction of the C-shaped upper groove 31, and therefore 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 arranged at a position where the top plate 63 can be supported in a well-balanced manner or at a position where they do not interfere with wiring.

[0099] In addition, the bottom plate portions 611, 621 are fixed to the mounting bracket 65 by the bolts 64. As a result, the opposing pieces 31b, 31b constituting 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.

[0100] Furthermore, 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, the top board support parts 613, 623 can be easily aligned horizontally, resulting in high assembly precision.

[0101] In addition, the first bracket 61 and the second bracket 62 are adapted to restrict relative horizontal movement between them by laterally engaging the bottom plate portion 611 of the first bracket 61 with the recess 624 of the second bracket 62, thereby enabling the first bracket 61 and the second bracket 62 to be accurately aligned with the top plate 63.

[0102] Furthermore, since each through hole 63a of the tabletop 63 is connected to the groove space S, the wiring within the groove space S can be brought out onto the tabletop 63 through the through holes 63a, thereby improving the functionality of the counter device 6.

[0103] Furthermore, since the top plate 63 is formed with approximately the same front-to-rear length as the beam 3, the top plate 63 can cover the upward groove 3A of the beam 3 along the longitudinal direction, preventing the accumulation of dirt in the upward groove 3A and providing an aesthetically pleasing appearance.

[0104] 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.

[0105] In addition, in this embodiment, the base of the bracket is exemplified as being approximately L-shaped consisting of a bottom plate portion and a side plate portion, but the shape can be freely changed as long as it is fixed to the bottom or side wall portion of the groove and its upper end is positioned above the opening of the groove.

[0106] In the present embodiment, the bracket is made by bending a single metal plate, but the present invention is not limited to this and each part may be made of a separate member. The bracket may also be made of a material other than metal, such as synthetic resin.

[0107] Furthermore, the bracket is not limited to being attached to the beam using bolts and mounting hardware, but may be attached to the beam by welding, for example.

[0108] 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 in the case of a top plate that extends only to the right or left from the beam, it may be supported at one end by a single bracket. Furthermore, 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.

[0109] The configuration of the recessed and projecting fitting parts of the pair of brackets may be freely changed. Furthermore, the recessed and projecting 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.

[0110] Furthermore, the material of the tabletop is not limited to wood, but may be 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 constructed. EXAMPLES

[0111] Next, a spacial structure according to a second embodiment will be described with reference to Fig. 8 to Fig. 10. Note that a description of the configuration overlapping with the configuration shown in the first embodiment will be omitted.

[0112] As shown in FIG. 8, a spatial structure 200 of the second embodiment is provided with a slide panel device 7 as a slide surface body device instead of the counter device 6. As shown in FIG.

[0113] 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 planar 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, and therefore 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. The panel attached to the C-shaped lower groove 32 (see FIG. 2) of the beam 3 may be a sliding panel instead of the fixed panel 5A.

[0114] Fixed panels 5A are disposed 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 appropriately switched between a closed state (see FIG. 9(a)) in which the sliding panels 73 are moved toward each other to close 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.

[0115] 10, a frame material 71 is attached to the right side surface 3f of the beam 3. Specifically, the frame material 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.

[0116] 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.

[0117] The base body 711 is constructed by fixing a first member 714 having an approximately downward U-shape and a second member 715 having an approximately downward U-shape formed by bending a single metal plate material, using a predetermined fixing means such as welding.

[0118] The first member 714 includes a left side plate portion 714a that faces the right side surface 3f of the beam 3, an upper plate portion 714b that extends horizontally to the right from the upper end of the left side plate portion 714a, a right side plate portion 714c that extends vertically downward from the right end of the upper plate portion 714b, and a lower plate portion 714d that extends horizontally to the left from the lower end of the right side plate portion 714c. The space between the lower portion of the left side plate portion 714a and the left portion of the lower plate portion 714d is open downward, and an insertion hole 714e through which the bolt 75 can be inserted is formed in the left side plate portion 714a.

[0119] The second member 715 includes 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 to 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.

[0120] Further, a through hole 715d is formed in the upper plate portion 715b of the second member 715 near the insertion hole 714e of the first member 714. The through hole 715d can be used to insert the bolt 75 into the insertion hole 714e and fasten the bolt 75 to the mounting bracket 74.

[0121] The cover body 712 is formed by bending a single metal plate material, and has a horizontal plate portion 712a extending horizontally to the right from the side surface of the right skirt plate portion 3d of the beam 3, and a U-shaped cover portion 712b having a downward U-shaped recessed 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.

[0122] The rail member 713 is formed by bending a single metal plate into a downward U-shape, and horizontal pieces 713b are provided extending in directions approaching 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 surfaces of the horizontal pieces 713b. That is, the rail member 713 has a rail groove formed on its inner side that opens downward.

[0123] Rail member 713 can be fitted into cover portion 712b of cover body 712 from below, and the bottom of cover portion 712b and the bottom of rail member 713 are fixed to upper plate portion 715b of second member 715 by bolts 76. Cover body 712 prevents bolts 75 from being exposed from below, resulting in an aesthetically pleasing appearance.

[0124] As described above, in the slide panel device 7, the frame material 71 is attached to the lower part of the side surface 3f of the beam 3 via the mounting brackets 74 and the bolts 75, the frame material 71 is provided with the rail member 713 forming a rail groove that opens downward, and the slide panel 73 is movably suspended relative to this rail member 713. In this way, since the slide panel 73 is movably suspended on the rail member 713 of the frame material 71 fixed to the beam 3 by utilizing the C-shaped side groove 34 of the beam 3, it is possible to suppress the swinging of the slide panel 73 relative to the beam 3.

[0125] 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 into a rail 77 laid on the floor surface. Since the fitting of the rail 77 with the downward groove 73b makes it possible to suppress the swinging of the sliding panel 73.

[0126] 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 clamped 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.

[0127] Furthermore, since the left end portion of the left side plate portion 715a and the left end portion of the horizontal plate portion 712a of the frame material 71 are in face contact with the side surface 3f and right side base plate portion 3d of the beam 3, 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. Furthermore, since the left end portion of the horizontal plate portion 712a contacts the side surface 3f of the beam 3 and the right side surface of the covering portion 712b contacts the lower plate portion 714d of the first member 714, the cover body 712 functions as a structural strength member for the frame material 71.

[0128] Moreover, 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, and the lower end of the cover member 4' extends to near the upper part of the frame material 71. With this, the cover member 4' can 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 excellent aesthetic appearance.

[0129] Moreover, 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, so that it is possible to decorate almost the entire surface of the left side surface 3f of the beam 3. In this way, by preparing the cover members 4, 4' having different vertical dimensions in advance, it is possible to decorate the beam 3 according to whether or not the frame material 71 is present.

[0130] In the second embodiment, the frame material is made up of a plurality of members, but it may be made up of a single member. Also, the material constituting the frame material can be freely changed.

[0131] In addition, in the second embodiment, the frame member is attached to the lower C-shaped gutter of the two upper and lower C-shaped gutter, but the frame member may be attached to the upper C-shaped gutter. In this case, the cover member can be attached to the lower part of the frame member by utilizing the lower C-shaped gutter. EXAMPLES

[0132] Next, a spacial structure according to a third embodiment will be described with reference to Fig. 11 to Fig. 14. Note that a description of the configuration overlapping with the configuration shown in the first embodiment will be omitted.

[0133] As shown in Fig. 11, curtains 81 are attached to the front surface of the spacial structure 300 of the third embodiment at a distance from each other on the left and right sides. Curtain devices 8 as sliding planar body devices are attached to the rear and right side surfaces of the spacial structure 300. Only the curtain device 8 on the right side surface of the spacial structure 300 will be described below.

[0134] 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 the sliding planar 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, and therefore a description thereof will be omitted.

[0135] Below the beam 3 that constitutes the curtain device 8, rail members 82 for movably suspending two curtains 81 are arranged side by side in the left-right direction (see Figure 13), and the state can be appropriately changed to a closed state in which the entire right side of the spatial structure 300 is blocked (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 of the front or rear sides of the right side of the spatial structure 300, forming an entrance / exit 300A on the other front or rear side (see Figure 12(c)).

[0136] As shown in Fig. 13, rail member 82 has a downward C-shape in cross section, and curtain 81 is suspended by rollers 81a provided at the upper end of curtain 81 so that curtain 81 can move. Rail member 82 is attached to the lower part of beam 3 in the left-right direction by utilizing C-shaped lower groove 32 of beam 3 and mounting bracket 83. Mounting bracket 83 is composed of plate-shaped base member 831 loosely inserted into C-shaped lower groove 32, bolt 832 as a hanging member extending downward from base member 831 through opening 32c of C-shaped lower groove 32, and plate-shaped support member 833 having a pair of support parts 833a inserted through bolt 832 and extending to the left and right sides from bolt 832. Support member 833 is engaged with the head of bolt 832 from below.

[0137] The left and right rail members 82 are supported by a pair of support parts 833a on both the left and right sides sandwiching the bolt 832. In this manner, by utilizing the C-shaped lower groove 32 provided in advance in the bottom 3c of the downward recessed groove 3B of the beam 3 and the mounting bracket 83, the pair of left and right rail members 82 can be lined up in the left-right direction and easily attached to the beam 3.

[0138] Specifically, 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 portions 833a and the bottom 3c of the downward groove 3B. Since the left and right rail members 82 can be sandwiched together between the pair of support portions 833a and the bottom 3c of the downward groove 3B by the operation of fastening the bolt 832 to the base member 831, the left and right rail members 82 can be firmly and easily attached below the beam 3.

[0139] The left and right rail members 82 are disposed in the downward recessed groove 3B when attached to the beam 3. This provides an aesthetically pleasing appearance as the left and right rail members 82 are not exposed from the sides due to the pair of skirt plate portions 3d. Also, the left and right rail members 82 can be arranged close to each other in the left-right direction to form a sliding structure, and since they do not protrude laterally beyond the beam, a compact structure can be achieved.

[0140] The left and right rail members 82 are in contact with a pair of bottom plate portions 3d, respectively. More specifically, the right rail member 82 has its left end portion supported by the support portion 833a at its lower left side 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 its lower right side 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.

[0141] Further, the pair of support portions 833a each have a support surface 833b that slopes downward toward the outside in the width direction from the bolt 832. 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 base plate portions 3d by the respective support surfaces 833b, so that the rail members 82 can be firmly attached to the beam 3.

[0142] In addition, a cover member 4 is attached to the side surface 3f of the beam 3 by utilizing a C-shaped gutter 33, and this cover member 4 extends to the lower end of the base 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 since the cover member 4 extends to the base plate portion 3d, the base plate portion 3d is not exposed from the side, resulting in an excellent aesthetic appearance.

[0143] Next, another embodiment of the curtain device will be described with reference to FIG.

[0144] 14, in the curtain device 800, six rail members 82 are arranged in a line in the left-right direction below the beam 3. More specifically, 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 arranged in the left and right C-shaped side gutters 34, respectively, and two rail members 82, one on each side, are attached to the bottom of the frame members 803 using mounting brackets 804, respectively.

[0145] The frame material 803 has a cross section that is U-shaped with its cross section facing downward, 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 a pair of upper and lower opposing pieces 34b that form the opening of the C-shaped gutter 34 are firmly held in the left-right direction by the heads of the bolts 802 and the mounting brackets 801.

[0146] Furthermore, since the side plate portion 803a of the frame material 803 is in face-to-face contact with the base plate portion 3d below the C-shaped gutter 34, twisting of the frame material 803 relative to the beam 3 is restricted, and the frame material 803 can be stably fixed.

[0147] 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, and the rail member 82 is supported on both the left and right sides of the bolt 806 by the pair of support portions 807a.

[0148] The rail member 82 is housed between the side plate portions 803a, 803b on both the left and right sides of the frame material 803, and is therefore not visible from the sides of the frame material 803, resulting in an aesthetically pleasing appearance.

[0149] Furthermore, 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 from between the side plate portions 803a, 803b and the pair of supports 807a.

[0150] In addition, a cover member 40 is attached to the side surface 3f of the beam 3 by utilizing the C-shaped gutter 33, and the cover member 40 extends to the frame material 803. This prevents the side surface 3f of the beam 3 from being exposed between the frame material 803 and the cover member 40, resulting in an excellent aesthetic appearance.

[0151] In this way, a maximum of six rail members 82 can be arranged in the left-right direction by attaching frame members 803 to the beam 3 as necessary. 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.

[0152] In this third embodiment, a configuration has been exemplified in which the support portion moves vertically integrally with the hanging member by fastening the hanging member to the base member, but the present invention is not limited to this. The support 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.

[0153] Furthermore, the rail member is not limited to being sandwiched between the lower surface of the beam and the support portion. For example, the rail member may be placed on and supported by the support portion.

[0154] In addition, in the third embodiment, the two rail members are housed between the pair of bottom plate portions, but the configuration of the pair of bottom plate portions may be omitted.

[0155] In addition, in the third embodiment, the frame material is attached to the lower C-shaped gutter of the two upper and lower C-shaped gutter, but the frame material may be attached to the upper C-shaped gutter. In this case, the cover member can be attached to the lower part of the frame material by utilizing the lower C-shaped gutter.

[0156] [Variations] Next, a modified example of a fixed panel that is attached using a beam will be described with reference to FIG.

[0157] As shown in Figure 15, the fixed panel 500 which constitutes part of the spatial structure of this modified example is composed of multiple upper and lower beams 3 which extend parallel to each other at a position lower than the beams 3 which connect the upper ends of the pillars 2, a first board 501 which is attached across the left faces of the multiple upper and lower beams 3, a second board 502 which is attached across the right faces of the multiple upper and lower beams 3, and a shelf device 503 which is attached to the lower part of the lower beam 3.

[0158] 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 locking portions 501c that can be locked to 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 surfaces 3f of the beams 3.

[0159] 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. Also, documents and the like can be attached to the front surface member 502a with pins or the like.

[0160] The shelf device 503 includes a plate-shaped mounting bracket 503a to be placed in the C-shaped lower groove 32 of the beam 3, a bolt 503b extending downward from the mounting bracket 503a through the opening 32c of the C-shaped lower groove 32, a plate-shaped body 503c extending to both the left and right sides from the lower end of the bolt 503b, and a cylindrical spacer 503d surrounding the outer periphery of the bolt 503b. Pens and other fixtures can be placed and stored on the plate-shaped body 503c.

[0161] By fastening the bolt 503b to the mounting bracket 503a, the spacer 503d is sandwiched in the vertical direction between the bottom 3c of the downward 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 sandwiched in the vertical direction by the mounting bracket 503a and the spacer 503d, so that the shelf device 503 can be firmly attached to the beam 3.

[0162] In addition, shelf device 503 can be accessed from both the left and right sides, that is, from the first board 501 and second board 502 sides, so that fixtures can be taken in and out of shelf device 503 from the first board 501 and second board 502 sides.

[0163] 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.
