[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2015-183497 Summary of the Invention [Problem to be solved by the invention]

[0004] However, the above-mentioned gypsum board mounting hardware was not suitable as a base for mounting gypsum board on the indoor side of a square pillar that supports the beams between beams of a building.

[0005] In view of the above circumstances, an object of the present invention is to provide a building structure in which gypsum boards can be efficiently attached to the indoor side of square pillars that support the beams between beams of a building, and a pillar-side gypsum board base that serves as the base for attaching the gypsum boards. [Means for solving the problem]

[0006] In order to solve the above problems, the building structure of the present invention includes a fixing member attached to the underside of a beam connected to a rectangular pillar of a building near a roof; One or more rectangular tubular members arranged with corners facing one or more column corner portions of the rectangular prism and having upper sides fixed to roof components of the building; a bent plate member that is disposed with the convex corner side of the corner abutting against the column corner portion, and the lower part of each of the rectangular tubular members is fixed to the concave corner side of the back surface of the convex corner side, and the left and right ends are fixed to the fixing member; a gypsum board fixed to the rectangular tubular member to cover the indoor side of the rectangular pillar near the roof; The present invention is characterized by comprising:

[0007] With the above configuration, a board mounting base surface is formed on the indoor side of the square pillar by the side surface of the square tubular member, the board mounting base surface being spaced apart from and parallel to the side surface of the square pillar. The gypsum board can then be easily attached to the side surface of the square pillar in parallel to the side surface, thereby efficiently constructing a building structure in which the indoor side of the square pillar near the roof is covered with the gypsum board.

[0008] The bent plate member and the rectangular tube member may be separate members that can be assembled three-dimensionally using fastening members. In this way, when transporting materials to a site, the bent plate member and the rectangular tube member can be separated to efficiently utilize the cargo space, and the bent plate member and the rectangular tube member can be assembled three-dimensionally at the site using fastening members.

[0009] The fastening member may be a screw that is screwed into the side surface of the rectangular tubular member from the bent plate member side, thereby achieving a structure in which the head of the fastening member is not present on the side surface of the rectangular tubular member.

[0010] The rectangular tubular member may be fixed to the roof component by a fastening member at an upper end bent piece integrally formed at the upper end of the rectangular tubular member, thereby making the rectangular tubular member firmly fixed to the roof component.

[0011] The bent plate member may have a bent portion at a lower side thereof, the bent portion being bent at the lower side to form a substantially U-shaped cross section, thereby improving the strength of the bent plate member.

[0012] The end face of the bent portion may abut against the surface portion that becomes the corner, thereby preventing the corner from bending excessively beyond a specified angle.

[0013] The fixing member may be a runner that is fastened to the interior side of the ceiling inner wall fixing hardware attached to the underside of the beam, thereby allowing the fixing member to be installed using the existing ceiling inner wall fixing hardware.

[0014] Furthermore, the column-side gypsum board base of the present invention is a column-side gypsum board base for fastening gypsum boards to be placed in the vicinity of the roof of a square column of a building, and is characterized by comprising: a square tube member placed with its corner portion facing one or more column corner portions of the square column; and a bent plate member placed with the convex corner side of the corner portion abutting against the column corner portion, and to which the lower part of each of the square tube members is fixed on the concave corner side of the back surface of the convex corner side.

[0015] In the column-side gypsum board base, the bent plate member and the rectangular tubular member may be separate members, and the bent plate member and the rectangular tubular member may be assembled three-dimensionally by fastening members. [Effects of the Invention]

[0016] According to the present invention, the board mounting base surface formed on the side of a rectangular prism makes it possible to easily attach gypsum boards to the side of the rectangular prism parallel to the side, thereby achieving the effect of efficiently constructing a building structure in which the indoor side of the rectangular prism near the roof and the indoor side of the beams are covered with the gypsum boards.

DETAILED DESCRIPTION OF THE INVENTION

[0018] Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. As shown in Fig. 1, a building 1 of this embodiment includes a fixing member 2, a square tube member 4 and a curved plate member 5 that form a column-side gypsum board base 3, gypsum board 6, gypsum board 7, a heat insulating material 8, and a beam-side gypsum board base 9. The example building structure (an example of an under-eaves exterior wall structure) shown in Fig. 1 shows a corner of the building 1, and beams 12 made of H-shaped steel are fixed to two faces of a square column 11 made of a square steel pipe. End plates provided at the ends of each beam 12 are bolted to joining plates welded to the square column 11.

[0019] In this embodiment, the fixing member 2 is attached to the underside of a beam 12 connected to a position near the roof of a rectangular pillar 11 of the building 1. As shown in Fig. 2(A), the fixing member 2 is made up of a runner 22 fastened to the indoor side of a ceiling interior wall fixing hardware 21 attached to the underside of the beam 12 by bolting.

[0020] As shown in Figure 2(B), the square tubular members 4 are arranged with their corners butted against one or more (three in this example building structure located on the indoor side) corners of the square pillars 11, and their upper sides are fixed to the roof components 13 of the building 1. The roof components 13 are made of, for example, ALC panels.

[0021] The bent plate member 5 has three corners 51 corresponding to the three column corners of the square column 11, and is positioned with the convex corner side of each corner 51 abutting against the column corners. The lower part of the square tube member 4 is fixed to each of the concave corners on the backside of the convex corner side of the bent plate member 5. The left and right ends of the bent plate member 5 are fixed to runners 22 with fastening members B (such as tapping screws).

[0022] As shown in Fig. 3, the column-side gypsum board base 3 is made up of separate members: a square tube member 4 and a curved plate member 5; the curved plate member 5 and the three square tube members 4 are three-dimensionally assembled and integrated using fastening members B. In the illustrated example of building structure, the column-side gypsum board base 3 has screws as fastening members B that are screwed into the side of the square tube member 4 from the side of the curved plate member 5. As a result, the indoor side of the portion of the bent plate member 5 that is parallel to the side of the square column 11 and the indoor side of the square tube member 4 are flush with each other to form a board base surface, and the screw heads of the fastening members B are not present on this board base surface.

[0023] Moreover, the square tubular member 4 has an upper end bent piece 41 integrally formed at the upper end of the square tubular member 4, which is fixed to the underside of the roof constituent material 13 by a fastening member B (such as a truss screw). Moreover, the strength of the square tubular member 4 is improved by having an embedded piece 42 formed at the upper end of the square tubular member 4 embedded within the square tubular member 4.

[0024] As shown in Figure 4(A), the gypsum board 7 is arranged to cover the lower side of the square tube member 4 on the column-side gypsum board base 3, the bent plate member 5, and the runner 22, and is fixed by driving fastening members B (gypsum board screws) into them.

[0025] As shown in FIG. 4(B), the heat insulating material 8 is disposed between the upper and lower flanges of the H-shaped steel beam 12, facing the indoor side of the web of the H-shaped steel beam 12.

[0026] As shown in Figure 5(A), the beam-side gypsum board base 9 has a bent piece portion 91 formed integrally by bending at the upper end of the beam-side gypsum board base 9, which is fixed to the underside of the roof component 13 by a fastening member B (such as a truss screw), and the lower side of the beam-side gypsum board base 9 is fixed by a fastening member B (gypsum board screw).

[0027] As shown in Figure 5(B), the gypsum board 6 covers the roof-near position of the square pillar 11 and the indoor side of the beam 12. In this embodiment, the gypsum board 6 is made up of two ordinary gypsum boards, one for underlayment and one for overlayment, and these two ordinary gypsum boards are fixed to the square tubular member 4 of the pillar-side gypsum board base 3 and the beam-side gypsum board base 9 with the joints of these two ordinary gypsum boards offset from each other by fastening members B (gypsum board screws). Note that the pillar-side gypsum board base 3 and the beam-side gypsum board base 9 do not have to be used together.

[0028] With the above configuration, the side surfaces of the square tubular members 4 form a board mounting base surface on the indoor side of the square pillar 11, spaced apart from and parallel to the side surface of the square pillar 11. The board mounting base surface makes it easy to mount the gypsum boards 6 on the side surfaces of the square pillar 11 in parallel to the side surfaces, and a building structure can be efficiently constructed in which the indoor side of the square pillar 11 near the roof and the indoor side of the beams 12 are covered with gypsum boards 6.

[0029] If the square tube member 4 and the bent plate member 5 that form the column-side gypsum board base 3 are separate members and the square tube member 4 and the bent plate member 5 can be assembled three-dimensionally using the fastening member B, when transporting materials to the site, the square tube member 4 and the bent plate member 5 can be separated to efficiently utilize the loading space, and the square tube member 4 and the bent plate member 5 can be assembled three-dimensionally at the site using the fastening member B.

[0030] When the screw serving as the fastening member B is screwed into the side surface of the rectangular tube member 4 from the bent plate member 5 side, the head of the screw serving as the fastening member B does not exist on the mounting surface of the gypsum board 7 .

[0031] When the upper end bent piece 41 formed integrally at the upper end of the rectangular tubular member 4 is fixed to the roof component 13 by the fastening member B, the rectangular tubular member 4 is firmly fixed to the roof component 13.

[0032] Furthermore, if the fixing member 2 consists of a runner 22 that is fastened to the indoor side of the ceiling interior wall fixing hardware 21 attached to the underside of the beam 12, the fixing member 2 can be efficiently installed using the existing ceiling interior wall fixing hardware 21.

[0033] 6, the bent plate member 5 has a bent portion 52 at the lower side of the bent plate member 5, the bent portion 52 having a generally U-shaped cross section that is open on the upper side by bending the lower side of the bent plate member 5. The presence of such a bent portion 52 improves the strength of the bent plate member 5.

[0034] Moreover, since both end faces of the bent portion 52 are configured to abut on the surface portion that becomes the corner portion 51, excessive bending of the corner portion 51 beyond the specified angle (90 degrees) can be suppressed.

[0035] Furthermore, the illustrated building structure was a structure for a protruding corner of the building 1, but is not limited to this. The column-side gypsum board substrate 3 used in other building parts may be of a type arranged in a straight section of the building 1, as shown in Fig. 7. In this type, the column-side gypsum board substrate 3 abuts the corners of the square tubular member 4 against two column corners on the indoor side of a square column 11. Furthermore, the column-side gypsum board substrate 3 shown in Fig. 7 and the column-side gypsum board substrates 3 described below may also be structured so that a bent portion 52 is formed in the bent plate member 5.

[0036] Furthermore, the column-side gypsum board base 3 used in other building parts may be a type that is a left-hand part of a straight section of the building 1 as shown in Figure 8(A), a type that is a right-hand part of a straight section of the building 1 as shown in Figure 8(B), or a type that is a left-hand part of a protruding corner of the building 1 as shown in Figure 8(C).

[0037] Furthermore, the column-side gypsum board base 3 used in other building parts may be a type that serves as the right-hand part of an outside corner of the building 1 as shown in Figure 9(A), a type that is used in an outside corner as shown in Figure 9(B), or a type that serves as an inside corner of the building 1 as shown in Figure 9(C).

[0038] Although the embodiments of the present invention have been described above with reference to the drawings, the present invention is not limited to the illustrated embodiments. Various modifications and variations can be made to the illustrated embodiments within the same scope as the present invention or within an equivalent scope. [Explanation of symbols]
