Description

[Technical field]

[0001] The present invention relates to a spatial structure that is installed independently on a floor surface and divides an indoor space such as an office or exhibition hall into spaces of a predetermined size. [Background technology]

[0002] An example of such a conventional spatial structure is described in Patent Document 1. This conventional spatial structure includes four support columns spaced apart in the front, back, left and right directions and supported by the floor surface via adjusters, four connecting rods connecting the upper ends of the opposing support columns, and a cross-shaped connecting rod connecting the opposing surfaces of the middle parts of the opposing beams, and multiple partition panels are attached between the opposing support columns.

[0003] [Patent Document 1] JP 2017-89242 A (page 4, figure 1) Summary of the Invention [Problem to be solved by the invention]

[0004] In the spatial structure described in Patent Document 1, the lower end of each pillar is only supported on the floor surface via an adjuster, so the strength of the spatial structure is relatively low, and it is expected that the entire spatial structure will sway in the event of an earthquake, etc. If this occurs, optional materials such as partition panels attached between the connecting rods and adjacent pillars cannot be stably supported, and there is a risk that, for example, when the optional material is a glass panel, the glass panel may be damaged.

[0005] Furthermore, not only is it impossible to increase the support strength of the bottom end of optional materials such as partition panels, but the workability of installing the optional materials is poor. Furthermore, if the bottom end of the optional materials is supported by the floor surface, there is a risk that the floor surface will be damaged by the weight of the optional materials.

[0006] The present invention has been made in consideration of such problems, and aims to provide a spatial structure that has increased strength to stably support optional materials such as partition panels, while also improving the support strength and ease of construction of the lower ends of the optional materials. [Means for solving the problem]

[0007] In order to solve the above problems, the spatial structure of the present invention comprises: A spatial structure including a plurality of columns each having a lower end supported on a floor surface via a height adjustment means, A flat base member is placed across the floor surface between the height adjustment means of adjacent pillars, and both longitudinal ends of the base member are fixed to the inner surfaces of the adjacent pillars by fixing means. According to this feature, by fixing both ends of the base member that contact the floor surface to the inner surfaces of the adjacent supports, a strong frame is formed by the adjacent supports, beams, and base member, and the strength of the spatial structure is increased. As a result, optional materials such as partition panels can be stably supported between the adjacent supports, beams, and base member. In addition, the base member can support the lower ends of optional materials such as partition panels, improving the support strength of the lower ends of the optional materials and the ease of installation of the optional materials.

[0008] The height adjustment means has a polygonal base placed on the floor surface, and a longitudinal side end of the base member is abutted against an inner side of the base. According to this feature, the base abuts against the base member and is prevented from rotating, so that the height of the support column can be prevented from changing after the height is adjusted.

[0009] The inner surfaces of adjacent pillars and both side ends of the base member are fixed by L-shaped fastening fittings, which are the fixing means and consist of an inward horizontal portion and an upright portion. According to this feature, both side ends of the base member can be easily and firmly connected to the inner surfaces of adjacent posts.

[0010] The base member is characterized in that a recessed groove is formed at a side end thereof, into which the lower end of the rising portion of the fixing metal fitting can be fitted. According to this feature, with the side end of the base member abutting against the inner edge of the pedestal, the side end of the base member can be fixed to the inner surface of the support column by a fixing bracket.

[0011] The inner surface of the support and the inner edge of the base are aligned in the same plane. According to this feature, the upright portion of the fixing bracket abuts against the inner surface of the support and the inner edge of the base, increasing the fixing area of ​​the upright portion, so that the upright portion can be firmly fixed to the inner surface of the support.

[0012] A long vertical hole is formed in either the upright portion of the fixing bracket or the inner surface of the support, into which a screw for fixing the upright portion to the inner surface of the support is inserted. According to this feature, after adjusting the height of the support pole, the support pole and the base member can be easily fixed with the fixing metal fittings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0014] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A spacial structure according to an embodiment of the present invention will be described below with reference to the accompanying drawings. EXAMPLES

[0015] Hereinafter, the spatial structure according to this embodiment will be described with reference to Fig. 1 to Fig. 8. As shown in Fig. 1, the spatial structure 1 of this embodiment is installed in a self-supporting manner on a floor surface F in order to divide a large indoor space such as an office or an exhibition hall into a square shape.

[0016] The spatial structure 1 comprises a frame body 2. The frame body 2 comprises six square tubular pillars 4 arranged at predetermined intervals in the front, rear, left and right directions, whose lower ends are supported on a floor surface F via adjusters 3 serving as height adjustment means, seven beams 5 arranged in the front, rear, left and right directions, whose upper ends of the pillars 4 are connected at right angles to each other to form a sun shape in a plan view, and seven flat base members 6 installed across the floor surface F between the adjusters 3, 3 of adjacent pillars 4, 4, with both longitudinal side ends fixed to the inner surfaces of the lower ends of the pillars 4, 4.

[0017] A glass sliding door 7 and two transparent or semi-transparent glass panels (partition panels) 8, 8 are attached between the left and right support columns 4, 4, the beam 5, and the base member 6 on the front side, with the glass panel 8 positioned at the rear (inside the room). In addition, three transparent or semi-transparent glass panels 8, 8, 8 are attached between the adjacent support columns 4, 4, the beam 5, and the base member 6 on both the left and right side sides and the rear side. Note that a steel panel, a wooden panel, or the like can be used instead of the glass panel 8. Furthermore, a steel sliding door, a wooden sliding door, or the like can be used for the glass sliding door 7.

[0018] The glass sliding door 7 is suspended from a guide rail with a downward U-shaped cross section, the upper end of which is attached to the underside of the beam 5, via multiple rollers (not shown) so as to be movable in the left-right direction. The upper end of each glass panel 8 is supported by fitting from below into a support member (not shown) with a downward U-shaped cross section, which is attached to the underside of the beam 5. The lower ends of the glass sliding door 7 and glass panels 8 are supported by a base member 6, as will be described in detail later. A door stop member 9 is attached to the inner surface of the left support pillar 4 on the front side, against which the left side end face of the glass sliding door 7 abuts. It goes without saying that the door stop member 9 and other decorative panels may be attached to the support pillar 4.

[0019] Next, the connection (fixing) structure between the support pillar 4 and the base member 6 in part A in FIG. 1 will be described with reference to FIGS.

[0020] First, the adjuster 3 will be described. The adjuster 3 is composed of a base 31 placed on the floor surface F, a male screw 32 extending in the vertical direction whose lower end is fixed to the center of the base 31, and a fixed nut 33 welded to the blocking material 4a. The upper part of the male screw 32 is inserted into a hole 4b in the center of the blocking material 4a fixed to the inside of the lower end of the support 4 having a square cross section, and is screwed into the nut 33 fixed to the blocking material 4a on the opposite side of the hole 4b. The base 31 forms a regular square (polygon) that is the same as the outer shape of the support 4, and the four sides of the base 31, front, back, left, and right, and the front, back, left, and right side surfaces of the support 4 are aligned on the same plane. The height of the support 4 can be adjusted by rotating the base 31 to adjust the amount of screwing between the male screw 32 and the nut 33.

[0021] The base member 6 is composed of a reinforcing member 61 formed of a steel plate having a thickness of, for example, about 1 to 2 mm, and an upper surface member 62 made of a thin plate material such as stainless steel, which covers the upper surface and both side surfaces in the width direction of the reinforcing member 61, and the vertical dimension of the base member 6 is, for example, about 10 mm. On both ends in the width direction of the upper surface member 62, downward bent portions 62a, 62a forming a 45-degree inclined surface, and inward bent portions 62b, 62b continuing from the lower ends of the downward bent portions 62a, 62a and the inward bent portions 62b, 62b are integrally provided, and both side surfaces in the width direction of the reinforcing member 61 are covered by these downward bent portions 62a, 62a and inward bent portions 62b, 62b. On the left end edge of the upper surface member 62 near the inside (room side), a U-shaped recessed groove 62c (see Figs. 2 and 3) is formed in a plan view. Furthermore, two screw insertion holes 62d, 62d are drilled in the left end portion of the upper surface member 62 toward the inside.

[0022] In the widthwise center of the reinforcing material 61, bent convex portions 61a, 61a with an upward U-shaped cross section in side view, whose upper surfaces abut against the back surface of the upper surface material 62, are formed continuously in the lengthwise direction at a distance from each other in the widthwise direction, and a hollow portion that opens downward is formed inside both bent convex portions 61a. In addition, upward pieces 61b, 61b whose upper ends abut against the back surface of the upper surface material 62 are continuously provided at both ends in the widthwise direction of the reinforcing material 61. The heights of the bent convex portions 61a, 61a and the upward pieces 61b, 61b are approximately the same. A U-shaped groove 61c in plan view is formed at the left end edge of the bent convex portion 61a on the inner side (inside the room) so as to be aligned vertically with the groove 62c of the upper surface material 42. Furthermore, two screw insertion holes 61d, 61d are drilled in the side end of the inner bent convex portion 46a so as to be aligned vertically with the screw insertion holes 62d, 62d of the upper surface member 62.

[0023] A fixing bracket 10 having an L-shape in front view and consisting of an inward horizontal portion 10a and an upright portion 10b that stands up from its outer end is used to connect the support 4 and the base member 6. Two female screw holes 11, 11 that match two screw insertion holes 61d, 62d of the reinforcing member 61 and the top surface member 62 are formed in the inward horizontal portion 10a. Furthermore, three long holes 12, 12, 12 that face in the vertical direction are formed in the upright portion 10b. The width dimension of the fixing bracket 10 is formed to be approximately equal to the width dimension of the hollow portion so that the inward horizontal portion 10a fits into the hollow portion of the bent convex portion 61a without any play.

[0024] The support column 4 and the base member 6 are connected, for example, in the following manner. [1] Adjusting the height of the support The height of the support 4 is adjusted by the adjuster 3.

[0025] [2] Assembling the base components The base member 6 is assembled. Specifically, with the upper surface member 62 placed on the reinforcing member 61, the inward horizontal portion 10a of the fixing bracket 10 is inserted into the hollow portion of the inner bent convex portion 61a of the reinforcing member 61. At this time, the lower end of the upright portion 10b is fitted from the side into the concave grooves 61c, 62c formed in the reinforcing member 61 and the upper surface member 62. Next, as shown in Figs. 4 and 5, two low head flat head screws 13, 13 are inserted from above into the two screw insertion holes 62d, 61d of the upper surface member 62 and the reinforcing member 61, and screwed into the female screw holes 11, 11 of the inward horizontal portion 10a of the fixing bracket 10. As a result, the upper surface member 62, the reinforcing member 61, and the inward horizontal portion 10a are fixed (see Figs. 4 and 5).

[0026] [3] Fixing the base member to the support Next, the longitudinal side end of the base member 6 is brought into contact with the inner side of the pedestal 31 of the adjuster 3, and the outer side of the rising portion 10b of the fixing bracket 10 is brought into contact with the inner side of the pedestal 31 and the inner side of the support 4, and the flat head screws 13 inserted into the three long holes 12 of the rising portion 10b are screwed into the female screw holes 14 formed on the inner side of the support 4 to fix the rising portion 10b to the inner side of the support 4. At this time, the inner side of the pedestal 31 and the inner side of the support 4 are aligned on the same plane, and the outer side of the rising portion 10b comes into contact with both of these surfaces, so that the fixing area of ​​the rising portion 10b is increased. Also, the lower end of the rising portion 10b is fitted into the recessed grooves 61c, 62c of the reinforcing member 61 and the upper surface member 62, so that the side end of the base member 6 can be brought into contact with the inner side of the pedestal 31.

[0027] When the base member 6 and the support pillar 4 are fixed, the side end of the base member 6 abuts against the inner side of the pedestal 31, preventing the pedestal 31 from rotating and preventing the height of the support pillar 4 from changing. In addition, a long hole 12 is formed in the standing portion 10b, making it easy to fix the base member 6 to the support pillar 4. In addition, both ends of the base member 6 are connected to the inner side surfaces of the left support pillars 4, 4, respectively, so that a strong frame is formed by the left and right support pillars 4, 4, the beam 5, and the base member 6. Although not shown in the drawings, the base members 6 on both the left and right side surfaces and the rear side are also connected to the inner side surfaces of the adjacent support pillars 4, 4 in the same procedure.

[0028] Next, the support structure of the bottom ends of the glass sliding door 7 and the glass panel 8 by the base member 6 on the front side will be described with reference to Fig. 6 and Fig. 7. As shown in Fig. 6, the glass sliding door 7 comprises a glass plate 7a and a frame member 7b with a downward U-shaped cross section that holds its bottom edge. The bottom end of a guide rod 15 facing up and down is fixed to the top surface of the top surface member 62 above the bent convex portion 61a on the outer side (outside the room) of the base member 6 by a bolt 16 inserted from inside the hollow portion of the bent convex portion 61a. The guide rod 15 is fixed in a position that is hidden by the glass sliding door 7 when the glass sliding door 7 is opened, so as not to impede passage when entering and exiting the spatial structure 1.

[0029] A horizontally rotating guide roller 17 is attached to the upper end of the guide rod 15, and by inserting this guide roller 17 into the U-shaped space in the edge frame material 6b, the lower end of the glass sliding door 7 is supported by the base member 6 so that it can move left and right.

[0030] As shown in Fig. 7, an edge frame material 18 is fitted into the lower edge of the glass panel 8. A panel support member 19 having an upward U-shaped cross section that is continuous in the longitudinal direction is fixed to the upper surface of the upper surface material 62 above the inner bent convex portion 61a of the base member 6 by screwing a plurality of bolts 20 inserted from above into square nuts 21 that are fitted in the internal space of the bent convex portion 61a and prevented from rotating.

[0031] A plurality of edge frame support members 22 having a downward U-shape when viewed from the side are fitted inside the panel support member 19, and by placing the edge frame material 18 on the upper surfaces of these plurality of edge frame support members 22, the lower end portion of the glass panel 8 is stably supported by the base member 6.

[0032] Next, the support structure of the lower end of the glass panel 8 by the base member 6 on the right side will be described with reference to Fig. 8. The support structures of the glass panel 8 on the left side and rear side are the same as those on the right side, and therefore their description will be omitted. Also, since the base member 6 on the right side supports only the glass panel 8, it is formed smaller in width than the base member 6 on the front side, and the bent convex portion 61a is formed in the center of the width direction of the reinforcing member 61. Other than this, it has the same configuration as the base member 6 on the front side, and therefore its detailed description will be omitted.

[0033] A panel support member 19 similar to that of the front glass panel 8 is fitted in the opposite left-right direction to the lower edge of the glass panel 8. Also, a panel support member 19 similar to the support form of the front glass panel 8 is fixed by bolts 20 and nuts 21 to the upper surface of the upper surface member 62 above the bent convex portion 61a of the base member 6, and a plurality of edge frame support members 22 are fitted inside this panel support member 19. By placing edge frame materials 18 on the upper surfaces of the plurality of edge frame support members 22, the lower end portion of the glass panel 8 on the right side surface side is stably supported by the base member 6.

[0034] As described above, in the spatial structure 1 according to the embodiment, by fixing both end portions of the base member 6 in contact with the floor surface F to the inner surfaces of the adjacent supports 4, 4, a strong frame is formed by the adjacent supports 4, 4, the beam 5, and the base member 6, thereby increasing the strength of the spatial structure 1. As a result, optional materials such as a glass sliding door 7 or a glass panel 8 can be stably supported between the adjacent supports 4, 4, the beam 5, and the base member 6.

[0035] In addition, the lower ends of the glass sliding door 7 and the glass panel 8 can be supported by incorporating bolts 16 and nuts 21 into the hollow portion of the bent convex portion 61a of the base member 6, thereby increasing the support strength and ease of installation at the lower ends, and there is no risk of damaging the floor surface F, as the base member 6 bears the load of the glass panel 8.

[0036] Furthermore, the base 31 of the adjuster 3 is a regular rectangle, and the longitudinal side end of the base member 6 abuts against its inner side to prevent the base 31 from rotating, thereby preventing the height of the support 4 from changing.

[0037] Furthermore, grooves 61c, 62c are formed on the side ends of the base member 6 into which the lower end of the upright portion 10b of the fixing bracket 10 fits, so that the side end of the base member 6 can be fixed to the inner surface of the support 4 with the side end of the base member 6 abutting against the inner edge of the pedestal 31.

[0038] Furthermore, since the inner surface of the support 4 and the inner edge of the base 31 are aligned on the same plane, the rising portion 10b of the fixing bracket 10 abuts against the inner surface of the support 4 and the inner edge of the base 31, increasing the fixing area of ​​the rising portion 10b, so that the rising portion 10b can be firmly fixed to the inner surface of the support 4. Furthermore, the rising portion 10b of the fixing bracket 10 is formed with a vertical long hole 12 into which a countersunk screw 13 is inserted for fixing the rising portion 10b to the inner surface of the support 4, so that the height of the support 4 can be adjusted with the base member 6 placed on the floor surface F.

[0039] Furthermore, the base member 6 is composed of a reinforcing material 61 and an upper surface material 62, and the upper surface material 62 is formed with a downward bent portion 62a covering both widthwise sides of the reinforcing material 61 and an inward bent portion 62b continuing from the lower end of the downward bent portion 62a, so that the strength of the base member 6 is high and the reinforcing material 61 can be covered by the upper surface material 62 in an attractive manner.

[0040] Furthermore, at the centre and both ends in the width direction of the reinforcing material 61, there are formed upwardly U-shaped bent convex portions 61a and upward pieces 61b which extend in the length direction and whose upper surfaces abut the rear surface of the upper surface material 62, respectively. This increases the load-bearing capacity of the base member 6 and enables the lower end of the glass panel 8 to be stably supported. At the same time, bolts 16 and nuts 21 for supporting the lower end of the glass sliding door 7 and glass panel 8 by the base member 6 can be inconspicuously accommodated at any position within the bent convex portion 61a.

[0041] Furthermore, since the downward bent portion 62a of the upper surface member 62 is formed into an inclined surface, it is possible to prevent tripping over the base member 6 when entering or exiting the spacial structure 1, and it is also possible to easily enter or exit the space structure 1 in a wheelchair.

[0042] Although the embodiments of the present invention have been described above with reference to the drawings, the specific configurations are not limited to these embodiments, and additions and modifications that do not deviate from the gist of the present invention are also included in the present invention.

[0043] For example, in the above embodiment, the base member 6 is made up of the reinforcing member 61 and the upper surface member 62, but the upper surface member 62 may be omitted.

[0044] Also, for example, in the above embodiment, the base 31 of the adjuster 3 as the height adjustment means is a regular rectangle with the side end of the base member 6 abutting against its inner edge to prevent rotation of the base 31, but it may also be a triangle or a polygon with more sides than a rectangle with the side end of the base member 6 abutting against its inner edge.

[0045] Furthermore, for example, in the above embodiment, the elongated hole 12 is formed in the rising portion 10b of the fixing metal fitting 10, but the elongated hole may be formed on the inner surface of the support pole 4.

[0046] Furthermore, for example, in the above embodiment, the base member 6 supports the glass sliding door 7 and the glass panel 8, but it can also support optional items such as a counter. In this case, the left-right width of the base member 6 and the position of the bent convex portion 61a can be appropriately changed in accordance with the width dimension of the optional item to be supported.
