Description

[Technical Field]

[0001] The present invention relates to a ceiling structure technology equipped with braces. [Background technology]

[0002] Conventionally, techniques for ceiling structures equipped with braces have been publicly known, as described in Patent Document 1, for example.

[0003] Patent Document 1 describes a rafter that supports a ceiling material, a rafter support that supports the rafter via a hanger at the lower end of a hanging bolt, and a brace that is fixed to the rafter and the rafter support via a brace lower mounting fixture. The brace is attached to the area where the rafter and the rafter support intersect via the brace lower mounting fixture.

[0004] With this configuration, the soffit supports and soffits are firmly fixed to the braces, so that shaking stresses (horizontal stresses) during an earthquake can be transmitted directly from the soffit supports and soffits to the braces. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Patent Application Laid-Open No. 2015-7326 Summary of the Invention [Problem to be solved by the invention]

[0006] However, with the technology described in Patent Document 1, stress tends to concentrate around the lower brace mounting fixture (around the lower end of the brace) during an earthquake, which can cause deformation or damage (hereinafter simply referred to as "deformation") to the joist support and joist located around this area. Furthermore, because the hanger is engaged with the joist support (not directly fixed), if the hanger is deformed by the shaking stress during an earthquake, the joist support may fall off the hanger. If the joist support, joist, or hanger is deformed in this way, the ceiling material may fall off.

[0007] The present invention has been made in consideration of the above-mentioned circumstances, and the problem it aims to solve is to provide a ceiling structure that can prevent ceiling materials from falling off. [Means for solving the problem]

[0008] The problem to be solved by the present invention is as described above, and the means for solving this problem will now be described.

[0009] That is, in claim 1, a siding that supports the ceiling material of the building, a siding support member that supports the siding, a brace that is installed between the building's skeleton and the siding support member and is fixed to the skeleton and the siding support member, a reinforcing member that is fixed to the siding support member and the brace, a hanging bolt that is fixed to the reinforcing member and supports the siding support member via the reinforcing member, a pipe member through which the suspension bolt is inserted, and the suspension bolt is fixed to the reinforcing member via the pipe member. It is something.

[0010] In claim 2, The structure comprises a siding that supports the ceiling material of a building, a siding support member that supports the siding, a brace that is installed between the building's skeleton and the siding support member and is fixed to the skeleton and the siding support member, a reinforcing member that is fixed to the siding support member and the brace, a hanging bolt that is fixed to the reinforcing member and supports the siding support member via the reinforcing member, and a fixing member for fixing the reinforcing member and the hanging bolt, and the hanging bolt supports the siding support member via a hanger fixed to the lower end of the hanging bolt in addition to the reinforcing member, and the fixing member is provided above the hanger. It is something.

[0011] In claim 3, The reinforcing member includes a first fixing portion for fixing the hanging bolt, and the first fixing portion is integrally formed with a second fixing portion for fixing the joist support member and the brace in the reinforcing member. It is something.

[0012] In claim 4, One brace is provided for the reinforcing member, and the brace and the hanging bolt are arranged side by side in a direction along the longitudinal direction of the soffit support member, and are spaced apart from each other in the longitudinal direction as they go upward. It is something. [Effects of the Invention]

[0016] The present invention has the following effects.

[0017] In the present invention, it is possible to prevent the ceiling material from falling off. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0019] In the following description, the up-down direction, left-right direction, and front-rear direction are defined according to the arrows shown in the drawings.

[0020] A ceiling structure 1 according to the first embodiment will be described below with reference to FIG.

[0021] The ceiling structure 1 is a ceiling structure in a building H. For convenience, FIG. 1 shows only a portion of the entire ceiling structure in the building H. Below, the ceiling structure 1 shown in FIG. 1, i.e., a portion of the entire ceiling structure, will be described. The ceiling structure 1 comprises hanging bolts 10, hangers 20, joist supports 30, joists 40, ceiling surface material 50, braces 60, first reinforcing brackets 70, second reinforcing brackets 80, and reinforcing pipes 90.

[0022] The hanging bolts 10 are attached to inserts (not shown) provided in the body A. In FIG. 1, three hanging bolts 10 are shown aligned in the front-to-rear direction. Of the three hanging bolts 10, the hanging bolt 10 located in the center of the front-to-rear direction is fixed to a first reinforcing bracket 70, as described below. The hanging bolts 10 support the joist 40 directly or indirectly via the first reinforcing bracket 70.

[0023] The hangers 20 support the soffit supports 30, which will be described later. The hangers 20 are fixed to the lower ends of the hanging bolts 10. In this embodiment, the hangers 20 are provided on two of the three hanging bolts 10, the hanging bolts 10 located on the front and rear sides.

[0024] The joist support 30 supports the joist 40 described later. The joist support 30 is formed in an elongated shape and is suspended from the skeleton A of the building H via suspension bolts 10 or the like.

[0025] The joists 40 support the ceiling surface material 50, which will be described later. The joists 40 are formed in an elongated shape and are arranged so as to be perpendicular to the joist support 30 in a plan view. The joists 40 are supported by the joist support 30 using clip members 41.

[0026] The ceiling surface material 50 constitutes the ceiling surface. The ceiling surface material 50 is formed, for example, from a plate-shaped plasterboard. The ceiling surface material 50 is fixed to the lower surface of the rough joist 40 using screws S (see FIG. 6).

[0027] The brace 60 is installed between the skeleton A of the building H and the joist support 30. The brace 60 has a roughly C-shaped cross section and is arranged with its longitudinal direction tilted relative to the vertical. In FIG. 1, one brace 60 is arranged so that it extends upward and to the right with respect to a first reinforcing bracket 70, which will be described later. The upper end of the brace 60 is fixed to the skeleton A of the building H by a predetermined fixing means. The lower end of the brace 60 is fixed to the joist support 30 by a screw B (see FIG. 4).

[0028] The configuration of the first reinforcing metal fitting 70 will be described in detail below with reference to FIGS.

[0029] As shown in Figure 1, the first reinforcing bracket 70, together with the second reinforcing bracket 80 and the reinforcing pipe 90, reinforces the ceiling structure 1. The first reinforcing bracket 70 is formed by appropriately bending a single flat metal member. The first reinforcing bracket 70 includes a main body 71, an upper end extension 72, a lower end extension 73, a claw 74, an upper fixing piece 78, and a lower fixing piece 79.

[0030] The main body 71 is the main structure of the first reinforcing metal fitting 70. The main body 71 is formed in a flat plate shape. The main body 71 is disposed with its longitudinal direction oriented in the left-right direction. The main body 71 is fixed to the brace 60.

[0031] The upper end extensions 72 are portions that extend rearward from the upper end of the main body 71. The upper end extensions 72 are formed on the left and right sides of the main body 71 so as to sandwich the upper fixed piece 78 therebetween.

[0032] The lower end extensions 73 are portions that extend rearward from the lower end of the main body 71. The lower end extensions 73 are formed on the left and right sides of the main body 71 so as to sandwich the lower fixed piece 79 therebetween.

[0033] The claw portions 74 extend generally downward from the left and right lower end portions of the main body portion 71. The left and right claw portions 74 are formed symmetrically in the left-right direction. The claw portions 74 are fixed to the second reinforcing bracket 80 and the siding support 30. The claw portions 74 include a first portion 75 and a second portion 76.

[0034] The first portion 75 is a portion between the second portion 76 and the main body portion 71. The first portion 75 is formed in a generally rectangular flat plate shape when viewed from the front. The first portion 75 is formed in an inclined shape that moves away from the main body portion 71 in the front-to-rear direction as it extends downward.

[0035] The second portion 76 extends downward from the first portion 75. The second portion 76 is formed in a generally rectangular flat plate shape when viewed from the front. The second portion 76 is provided with its plate surface facing the front-rear direction. The rear side of the second portion 76 is formed so as to be generally flush with the front side of the main body 71 in the front-rear direction. The second portion 76 is formed with screw holes 77 that penetrate in the front-rear direction.

[0036] The upper fixing piece 78 is the portion to which the hanging bolt 10 is fixed. The upper fixing piece 78 extends forward from the center of the left and right sides of the upper end of the main body 71. The upper fixing piece 78 is formed in a substantially rectangular flat plate shape in a plan view. An upper through-hole 78a is formed in the upper fixing piece 78. The inner diameter of the upper through-hole 78a is formed to be substantially the same as the outer diameter of the hanging bolt 10.

[0037] The lower fixed piece 79 is a portion to which the suspension bolt 10 is fixed together with the upper fixed piece 78. The upper fixed piece 78 is disposed below the upper fixed piece 78 and extends forward from the center of the left and right sides of the lower end of the main body 71. The lower fixed piece 79 has substantially the same shape as the upper fixed piece 78. A lower through-hole 79a is formed in the lower fixed piece 79. The inner diameter of the lower through-hole 79a is formed to be substantially the same as the outer diameter of the suspension bolt 10.

[0038] In this way, in the first reinforcing bracket 70, the upper fixing piece 78 and the lower fixing piece 79 are formed integrally with the main body 71 and the claw portion 74. That is, in the first reinforcing bracket 70, the portion fixed to the hanging bolt 10 (the upper fixing piece 78 and the lower fixing piece 79) is formed integrally with the portion fixed to the brace 60 and the portions fixed to the second reinforcing bracket 80 and the joist support 30.

[0039] The configuration of the second reinforcing metal fitting 80 will be described in detail below with reference to FIGS.

[0040] As shown in Figure 1, the second reinforcing bracket 80, together with the first reinforcing bracket 70 and the reinforcing pipe 90, reinforces the ceiling structure 1. The second reinforcing bracket 80 is formed by appropriately bending a single flat metal member. The second reinforcing bracket 80 includes a main body 81, an upper extension 82, and a lower extension 83.

[0041] The main body 81 is the main structure of the second reinforcing metal fitting 80. The main body 81 is formed in a flat plate shape. The main body 81 is arranged with its longitudinal direction oriented in the left-right direction. The main body 81 is formed with a plurality of screw holes 89 that penetrate in the front-to-rear direction. A plurality of screw holes 89 (three in this embodiment) are formed at intervals from each other in the left-to-right direction.

[0042] The upper end extension 82 extends rearward from the upper end of the main body 81. The rear end of the upper end extension 82 is formed into a rib shape bent downward. The front-to-rear length of the space defined by the upper end extension 82 and the main body 81 is formed to be approximately the same as the front-to-rear length of the soffit support 30.

[0043] The lower end extension 83 is a portion that extends rearward from the lower end of the main body 81. The rear end of the lower end extension 83 is formed into a rib shape that is bent upward. The length of the lower end extension 83 in the front-to-rear direction is formed to be longer than the length of the upper end extension 82 in the front-to-rear direction.

[0044] The configuration of the reinforcing pipe 90 will be described in detail below with reference to FIGS. 1 and 4 to 6. FIG.

[0045] The reinforcing pipe 90, together with the first reinforcing metal fitting 70 and the second reinforcing metal fitting 80, reinforces the ceiling structure 1. Specifically, the reinforcing pipe 90 reinforces a specific suspension bolt 10 (in this embodiment, the suspension bolt 10 in the center between the front and rear as shown in FIG. 1 ) among the multiple suspension bolts 10 that make up the ceiling structure 1. Note that hereinafter, unless otherwise specified, the suspension bolt 10 in the center between the front and rear will be simply referred to as the "suspension bolt 10." The reinforcing pipe 90 is formed from a hollow square pipe made of metal or resin. The length of the reinforcing pipe 90 is shorter than the length of the suspension bolt 10. The inner diameter of the reinforcing pipe 90 is formed to be approximately the same as or slightly larger than the outer diameter of the suspension bolt 10.

[0046] As shown in FIG. 5 , a hanging bolt 10 is inserted into a reinforcing pipe 90. In this embodiment, the entire reinforcing pipe 90 is inserted except for the lower portion of the hanging bolt 10. In other words, the hanging bolt 10 is exposed below the reinforcing pipe 90. The upper end of the reinforcing pipe 90 abuts against the body A from below via a washer 91. The lower end of the reinforcing pipe 90 is tightened upward via the washer 91 by a nut N inserted into the hanging bolt 10. In this way, the reinforcing pipe 90 is fixed to the hanging bolt 10.

[0047] As a result, the reinforcing pipe 90 can improve the strength of the suspension bolt 10 (for example, strength against compressive force in the axial direction) and suppress buckling of the suspension bolt 10.

[0048] The method of fixing the reinforcing pipe 90 to the suspension bolt 10 is not limited to the method described above. For example, the upper end of the reinforcing pipe 90 may not be brought into contact with the body A, but may be tightened downward by a nut inserted into the suspension bolt 10 via a washer 91. This leaves a gap between the upper end of the reinforcing pipe 90 and the body A, allowing the suspension bolt 10 to be exposed above the reinforcing pipe 90.

[0049] The manner in which the ceiling structure 1 is attached will be described below with reference to FIGS. 1 and 4 to 6. FIG.

[0050] First, among the mounting modes for the ceiling structure 1, the mounting mode for the second reinforcing metal fitting 80 will be described.

[0051] In this embodiment, two second reinforcing metal fittings 80 are attached as described above. The attachment manner of the two second reinforcing metal fittings 80 is substantially the same, except that they are symmetrical in the left-right direction. Therefore, the following description will focus mainly on the second reinforcing metal fitting 80 on the right side, and description of the second reinforcing metal fitting 80 on the left side will be omitted where appropriate.

[0052] The second reinforcing bracket 80 is hooked from above onto the siding support 30 by the upper end extension 82. More specifically, the upper end of the siding support 30 is positioned in the space defined by the main body 81 and upper end extension 82 of the second reinforcing bracket 80. The rear side of the main body 81 abuts against the front side of the siding support 30. The lower side of the upper end extension 82 abuts against the upper side of the siding support 30. The second reinforcing bracket 80 is fixed to the siding support 30 by screws S inserted into screw holes 89 (see FIG. 3). In other words, the second reinforcing bracket 80 is fixed to the siding support 30 by fixing means (screws) inserted laterally.

[0053] Furthermore, when a worker performs the work of fixing the second reinforcing bracket 80 to the joist support 30, the second reinforcing bracket 80 can be hooked onto the joist support 30 and fastened (temporarily fastened) even before it is fixed with the screws S. This improves the ease of installation when performing the work of installing the second reinforcing bracket 80.

[0054] Furthermore, the lower surface of the lower end extension 83 of the second reinforcing bracket 80 is flush in the vertical direction with the lower surface of the joist 40. With the lower surface of the lower end extension 83 in contact with the upper surface of the ceiling surface material 50, the second reinforcing bracket 80 is fixed to the ceiling surface material 50 with a plurality of screws S inserted from below to above the ceiling surface material 50. In this way, the second reinforcing bracket 80 is fixed to the joist support 30 and the ceiling surface material 50, respectively.

[0055] Next, among the mounting modes for the ceiling structure 1, a mounting mode for the first reinforcing metal fitting 70 will be described.

[0056] In this embodiment, the attachment modes of the right and left halves of the first reinforcing bracket 70 are substantially the same except that they are symmetrical in the left-right direction. Therefore, the following description will focus on the right half of the first reinforcing bracket 70, and description of the left half will be omitted as appropriate.

[0057] The first reinforcing bracket 70 is provided above the soffit support 30, clip member 41, and second reinforcing bracket 80. The first reinforcing bracket 70 is provided so as to be in direct or indirect contact with the soffit support 30, clip member 41, and second reinforcing bracket 80 from above. Specifically, the lower end extension 73 of the first reinforcing bracket 70 is placed directly on the clip member 41 and second reinforcing bracket 80. Furthermore, the lower end extension 73 of the first reinforcing bracket 70 is placed indirectly on the soffit support 30 (via the clip member 41 and second reinforcing bracket 80).

[0058] Furthermore, the rear surface of the second portion 76 of the claw portion 74 of the first reinforcing bracket 70 abuts from the front side against the front surface of the main body 81 of the second reinforcing bracket 80. In this way, the claw portion 74 of the first reinforcing bracket 70 abuts against the siding support 30 via the main body 81 of the second reinforcing bracket 80.

[0059] Additionally, the first reinforcing bracket 70 is fixed to the second reinforcing bracket 80 and the siding support 30 by screws S inserted through screw holes 77 (see FIG. 2). In this way, the first reinforcing bracket 70 and the second reinforcing bracket 80 are fastened together via screw holes (screw holes 77 and 89) that are provided so as to overlap in the front-to-rear direction.

[0060] Furthermore, the first reinforcing bracket 70 abuts against the rear side surface of the brace 60. Specifically, the brace 60 abuts against the first reinforcing bracket 70 so as to diagonally cross the right half of the first reinforcing bracket 70 when viewed from the front.

[0061] Furthermore, the first reinforcing bracket 70 is fixed to the brace 60 with a screw S. The screws S are provided at both the top and bottom of the first reinforcing bracket 70. In this way, the brace 60 is not only fixed directly to the joist support 30 with the screws B, but also indirectly to the joist support 30 via the first reinforcing bracket 70 and the second reinforcing bracket 80. In other words, the brace 60 can support the ceiling surface material 50 not only via the joist 40 supported by the joist support 30, but also via the first reinforcing bracket 70 and the second reinforcing bracket 80 (more specifically, the lower end extension 83). In other words, the brace 60 can support the ceiling surface material 50 not only at a location relatively close to the lower end of the brace 60, but also at a location relatively far away.

[0062] Furthermore, the first reinforcing bracket 70 is directly fixed to the hanging bolt 10 by the upper fixing piece 78 and the lower fixing piece 79. Specifically, the hanging bolt 10 is inserted from above into the upper through-hole 78a of the upper fixing piece 78 and the lower through-hole 79a of the lower fixing piece 79 (see FIG. 2). The upper fixing piece 78 and the lower fixing piece 79 are then tightened from above and below by nuts N inserted into the hanging bolt 10. This fixes the hanging bolt 10 to the upper fixing piece 78 and the lower fixing piece 79, respectively. In this way, the hanging bolt 10 is fixed to the ceiling surface material 50 via the first reinforcing bracket 70 and the second reinforcing bracket 80.

[0063] The following describes the effects and advantages obtained from the ceiling structure 1 described above.

[0064] That is, in the ceiling structure 1, the reinforcing pipe 90 is fixed to the hanging bolt 10, and the hanging bolt 10 is fixed to the first reinforcing bracket. As a result, the hanging bolt 10, together with the brace 60, can function as a typical pair (two) of braces arranged in a V-shape in side view. The ceiling structure 1 also has a first reinforcing bracket 70 and a second reinforcing bracket 80. With this configuration, the ceiling structure 1 can effectively prevent the ceiling surface material 50 from falling off.

[0065] Specifically, for example, when the ceiling surface material 50 shakes during an earthquake, the horizontal force generated in the ceiling surface material 50 is effectively transmitted to the joist support 30 by the first reinforcing bracket 70 and the second reinforcing bracket 80, and is then effectively transmitted to the hanging bolts 10 (reinforcing pipes 90) and the braces 60. In this way, the hanging bolts 10 and the braces 60 displace the various members that make up the ceiling structure 1 as a whole, preventing them from colliding with, for example, the walls of the building H, and preventing the ceiling surface material 50 from falling off due to the collision.

[0066] Furthermore, the hanging bolts 10 and braces 60 are fixed to the ceiling surface material 50 not only via the siding support 30 and siding 40, but also via the siding support 30 and the second reinforcing bracket 80 (more specifically, the lower end extension 83). This makes it possible to prevent stress from concentrating between the hanging bolts 10 and braces 60 and the ceiling surface material 50. This makes it possible to prevent various components (for example, the siding support 30) from being deformed due to stress concentration, and to prevent the ceiling surface material 50 from falling off due to this deformation.

[0067] Furthermore, the hanging bolt 10 is directly fixed to the upper fixed piece 78 and the lower fixed piece 79 of the first reinforcing bracket 70 using nuts N. In this way, even if the ceiling surface material 50 shakes during an earthquake, causing the upper fixed piece 78 and the lower fixed piece 79 to deform, the upper fixed piece 78 and the lower fixed piece 79 can be prevented from coming off the hanging bolt 10. This makes it possible to prevent the ceiling surface material 50 from falling off during an earthquake.

[0068] The ceiling structure 1 according to the second embodiment will be described below with reference to Figures 7 and 8. For convenience, the suspension bolts 10 are indicated by two-dot chain lines in Figures 7 and 8.

[0069] In the ceiling structure 1 according to the second embodiment, the method of fixing the first reinforcing bracket 70 and the suspension bolt 10 is different from that in the first embodiment. Specifically, in the ceiling structure 1 according to the second embodiment, as shown in Fig. 7, the first reinforcing bracket 70 does not have an upper fixing piece 78 or a lower fixing piece 79, and the first reinforcing bracket 70 and the suspension bolt 10 are fixed via a specified metal piece (first mounting metal piece 110).

[0070] The first mounting bracket 110 is a metal member. The first mounting bracket 110 is formed into a substantially L-shape by a reinforcing bracket side fixing portion 111 and a hanging bolt side fixing portion 112, each of which is a flat portion. The reinforcing bracket side fixing portion 111 abuts against the first reinforcing bracket 70 and is fixed with a screw S. The hanging bolt side fixing portion 112 protrudes forward from the reinforcing bracket side fixing portion 111 and has a hole (not shown) that penetrates it vertically. Multiple (two) first mounting brackets 110 are provided, and are arranged at the upper and lower ends of the first reinforcing bracket 70, respectively.

[0071] In this way, the hanging bolt 10 is fixed to the first reinforcing bracket 70 via the two first mounting hardware 110. Specifically, the hanging bolt 10 is inserted from above into each of the holes in the hanging bolt-side fixing portions 112 of the two first mounting hardware 110. Then, the two hanging bolt-side fixing portions 112 are tightened from above and below by nuts N inserted into the hanging bolts 10, respectively. In this way, the two first mounting hardware 110 and the hanging bolts 10 are fixed.

[0072] In this way, the hanging bolt 10 is fixed to the two first mounting hardware 110 (which are fixed to the first reinforcing brackets 70 by screws S) with nuts N. In other words, the hanging bolt 10 is fixed to the first mounting hardware 110 and the first reinforcing bracket 70 using a predetermined fixing means. As a result, the ceiling structure 1 according to the second embodiment can also achieve the same effects as the ceiling structure 1 according to the first embodiment.

[0073] In the second embodiment, the configuration of the first mounting hardware 110 is not limited to that described above. For example, in a ceiling structure 1 according to another example of the second embodiment shown in FIG. 8, the first mounting hardware 110 has a suspension bolt-side fixing portion 112 and a member (connecting portion 113) that connects two reinforcing bracket-side fixing portions 111 together. The connecting portion 113 abuts against the first reinforcing bracket 70 and is fixed with a screw S. As a result, in the ceiling structure 1 according to another example of the second embodiment, the number of required hardware is reduced to one, reducing the number of parts and improving workability. Furthermore, the abutment of the connecting portion 113 of the first mounting hardware 110 with the first reinforcing bracket 70 increases the out-of-plane rigidity of the first reinforcing bracket 70.

[0074] A ceiling structure 1 according to the third embodiment will be described below with reference to Figures 9 and 10. For convenience, in Figures 9 and 10, a reinforcing pipe 90 is indicated by a two-dot chain line.

[0075] In the ceiling structure 1 according to the third embodiment, the method of fixing the first reinforcing bracket 70 and the suspension bolt 10 differs from that of the first and second embodiments. Specifically, in the ceiling structure 1 according to the third embodiment, as shown in Fig. 9, the first reinforcing bracket 70 does not have an upper fixing piece 78 and a lower fixing piece 79, as in the second embodiment, and the first reinforcing bracket 70 and the suspension bolt 10 are fixed via a specified metal fitting (second mounting metal fitting 210). Furthermore, in the ceiling structure 1 according to the third embodiment, the suspension bolt 10 is fixed to the first reinforcing bracket 70 via a reinforcing pipe 90.

[0076] Specifically, as shown in Fig. 9, the lower end of the hanging bolt 10 is attached to the siding support 30 via the hanger 20, similar to the two hanging bolts 10 arranged on the front and rear sides shown in Fig. 1. That is, the lower end of the hanging bolt 10 is inserted from above into a hole (not shown) at the upper end of the hanger 20, and is tightened from above and below by a nut N inserted into the hanging bolt 10. In this way, the lower end of the hanging bolt 10 is fixed to the hanger 20.

[0077] Unlike the first and second embodiments, the lower end of the reinforcing pipe 90 is located near the lower end of the suspension bolt 10. In this way, the lower part of the reinforcing pipe 90 is formed so as to overlap with the first reinforcing metal fitting 70 in a front view.

[0078] The second mounting bracket 210 is a metal member. The second mounting bracket 210 is formed into a substantially L-shape by a reinforcing bracket-side fixing portion 211 and a hanging bolt-side fixing portion 212, each of which is a flat portion. The reinforcing bracket-side fixing portion 211 abuts against the first reinforcing bracket 70 and is fixed with a screw S. The hanging bolt-side fixing portion 212 protrudes forward from the reinforcing bracket-side fixing portion 211 and has a hole (not shown) that penetrates it from left to right. Multiple (two) second mounting brackets 210 are provided, and are arranged on the left and right sides of the reinforcing pipe 90 at the upper end of the first reinforcing bracket 70.

[0079] In this way, the suspension bolt 10 is fixed to the first reinforcing metal fitting 70 via the reinforcing pipe 90 and the two second mounting hardware 210. Specifically, the reinforcing pipe 90 is inserted vertically between the suspension bolt-side fixing portions 212 of the two second mounting hardware 210. The reinforcing pipe 90 is then fixed to each of the two suspension bolt-side fixing portions 212 with screws S.

[0080] In this way, the hanging bolt 10 is fixed to the reinforcing pipe 90 and the second mounting hardware 210 using a predetermined fixing means. As a result, the ceiling structure 1 according to the third embodiment can also achieve the same effects as the ceiling structure 1 according to the first embodiment. Furthermore, in the third embodiment, the first reinforcing metal fitting 70 is fixed to the hanging bolt 10 via the reinforcing pipe 90, so deformation of the hanging bolt 10 can be effectively suppressed.

[0081] It should be noted that in the third embodiment, the configuration of the second mounting hardware 210 is not limited to that described above. For example, in a ceiling structure 1 according to a first modified example of the third embodiment shown in Fig. 10, the second mounting hardware 210 is formed so that the suspension bolt side fixing portion 212 connects the two reinforcing hardware side fixing portions 211 between them. The suspension bolt side fixing portion 212 is abutted against the rear side of the reinforcing pipe 90 (the surface on the first reinforcing hardware 70 side) in advance, and is fixed to the reinforcing pipe 90 with a screw S. As a result, in the ceiling structure 1 according to the modified example of the third embodiment, the number of required hardware is reduced to one, reducing the number of parts and improving workability.

[0082] Furthermore, in the third embodiment, the configuration of the reinforcing pipe 90 is not limited to the one described above. For example, in a ceiling structure 1 according to a second modified example of the third embodiment shown in FIG. 11 , the reinforcing pipe 90 is formed so that its length along the longitudinal (vertical) direction is slightly longer than the vertical width of the first reinforcing bracket 70. In other words, the upper end of the first reinforcing bracket 70 is positioned slightly higher than the first reinforcing bracket 70. In this way, the reinforcing pipe 90 is provided only near the lower end of the hanging bolt 10 (i.e., the portion generally aligned with the first reinforcing bracket 70). Even with this configuration, the reinforcing pipe 90 can improve the strength of the hanging bolt 10 and prevent buckling of the hanging bolt 10.

[0083] The ceiling structure 1 according to the fourth embodiment will be described below with reference to Figures 12 and 13. For ease of explanation, in Figures 12 and 13, illustrations of various parts such as the brace 60 are omitted as appropriate, and the actual shapes and the like are simplified.

[0084] In the ceiling structure 1 according to the fourth embodiment, the method of fixing the first reinforcing metal fitting 70 and the suspension bolt 10 differs from that of the first, second, and third embodiments. Specifically, in the ceiling structure 1 according to the fourth embodiment, as shown in Fig. 12, a reinforcing pipe 90 is not provided, and the first reinforcing metal fitting 70 and the suspension bolt 10 are fixed via a predetermined metal fitting (third mounting metal fitting 310). Furthermore, the ceiling structure 1 according to the fourth embodiment is reinforced by a predetermined metal fitting (third reinforcing metal fitting 370).

[0085] The third mounting hardware 310 is a metal member. The third mounting hardware 310 includes a hanging bolt holding portion 311 and a first reinforcing bracket side fixing portion 312. The hanging bolt holding portion 311 is a portion that holds the hanging bolt 10. The hanging bolt holding portion 311 is formed in a substantially cylindrical shape with an open rear side so that it can be fitted onto the hanging bolt 10. The inner diameter of the hanging bolt holding portion 311 is formed to be substantially the same as the outer diameter of the hanging bolt 10. In this way, the third mounting hardware 310 holds the hanging bolt 10 so that it is difficult for the hanging bolt 10 to move relative to the third mounting hardware 310.

[0086] 12(b), a gap is provided between the hanging bolt 10 and the first reinforcing bracket 70, but this gap can also be eliminated. For example, if the hanging bolt 10 is attached so that it abuts against the first reinforcing bracket 70 using the third mounting bracket 310, the hanging bolt 10 can be held relative to the third mounting bracket 310 so that it is more difficult for it to move.

[0087] The first reinforcing bracket side fixing portions 312 are formed so as to extend outward in the left-right direction from the left and right rear end portions of the hanging bolt holding portion 311. The first reinforcing bracket side fixing portions 312 abut against the first reinforcing bracket 70 and are fixed with screws S. Multiple (two) third mounting brackets 310 are provided, and are arranged above and below the first reinforcing bracket 70, respectively.

[0088] The third reinforcing bracket 370 is a metal angle bar. The third reinforcing bracket 370 is formed into a generally L-shape by a first reinforcing bracket-side fixing portion 371 and a rising portion 372, each of which is a flat plate. The first reinforcing bracket-side fixing portion 371 abuts against the first reinforcing bracket 70 and the soffit support 30, and is fixed with screws (not shown). The rising portion 372 is formed to protrude forward (rise up) from the end of the first reinforcing bracket-side fixing portion 371 on the hanging bolt 10 side in the left-right direction.

[0089] The third reinforcing bracket 370 is provided with its longitudinal direction facing the vertical direction. The upper end of the third reinforcing bracket 370 is provided near the upper end of the first reinforcing bracket 70. The lower end of the third reinforcing bracket 370 is provided near the lower end of the soffit support 30. In this way, the third reinforcing bracket 370 is provided so as to straddle the first reinforcing bracket 70 and the soffit support 30 in the vertical direction. Multiple (two) third reinforcing brackets 370 are provided, and are arranged on the left and right sides of the hanging bolt 10.

[0090] In this way, the hanging bolt 10 is fixed to the first reinforcing bracket 70 via the two third mounting brackets 310. In addition, third reinforcing brackets 370 are provided on the left and right sides of the hanging bolt 10, so the hanging bolt 10 can be restrained by the first reinforcing bracket 70. As a result, the ceiling structure 1 according to the fourth embodiment can also achieve the same effects as the ceiling structure 1 according to the first embodiment.

[0091] Furthermore, in the fourth embodiment, the third reinforcing bracket 370 has a length in the vertical direction and is arranged to straddle the first reinforcing bracket 70 and the siding support 30 in the vertical direction, thereby effectively suppressing deformation of the hanging bolt 10. Furthermore, the first reinforcing bracket-side fixing portion 371 of the third reinforcing bracket 370 abuts against the first reinforcing bracket 70, thereby increasing the out-of-plane rigidity of the first reinforcing bracket 70.

[0092] In the fourth embodiment, the configuration of the third mounting bracket 310 is not limited to the above. For example, in a ceiling structure 1 according to another example of the fourth embodiment shown in FIG. 13, the third mounting bracket 310 is formed to have a length in the vertical direction. Specifically, the third mounting bracket 310 shown in FIG. 13 can be formed into one, rather than the multiple (two) third mounting brackets shown in FIG. 12, by making its vertical length closer to the vertical length of the first reinforcing bracket 70. Specifically, the vertical length of the third mounting bracket 310 shown in FIG. 13 is formed to be longer than half the vertical length of the first reinforcing bracket 70. This reduces the number of required hardware and the number of parts in the ceiling structure 1 according to another example of the third embodiment, thereby improving workability. Furthermore, the first reinforcing bracket-side fixing portion 312 of the third mounting bracket 310 abuts against the first reinforcing bracket 70 over a relatively large area, thereby increasing the out-of-plane rigidity of the first reinforcing bracket 70.

[0093] The ceiling structure 1 according to the fifth embodiment will be described below with reference to FIG.

[0094] The ceiling structure 1 of the fifth embodiment differs from the first embodiment in that, whereas in the ceiling structure 1 of the first embodiment, the brace 60, the first reinforcing bracket 70 and the second reinforcing bracket 80 were attached to the soffit support 30, the brace 60, the first reinforcing bracket 70 and the second reinforcing bracket 80 are attached to the soffit support member 130.

[0095] The siding support member 130 is a long member. The siding support member 130 is arranged above a plurality of siding support members 30 (three in FIG. 14 ) with its longitudinal direction perpendicular to the longitudinal direction of the siding support members 30. The siding support member 130 is arranged to span the three siding support members 30 and is fixed to these siding support members 30.

[0096] The first reinforcing metal fitting 70 and the second reinforcing metal fitting 80 are attached in the same manner as in the manner in which they are attached to the joist support 30 of the ceiling structure 1 according to the first embodiment.

[0097] As described above, in the ceiling structure 1, A joist 40 supporting a ceiling surface material 50 (ceiling material) of the building H; A siding support 30 (and / or a siding joint member 130) (siding support member) that supports the siding 40; A brace 60 is installed between the skeleton A of the building H and the joist support 30 (joist support member) and fixed to the skeleton A and the joist support 30 (joist support member), A first reinforcing metal fitting 70 (reinforcing member) fixed to the sill support 30 (sill support member) and the brace 60; A hanging bolt 10 fixed to the first reinforcing metal fitting 70 (reinforcing member) and supporting the siding support 30 (siding support member) via the first reinforcing metal fitting 70 (reinforcing member); It is equipped with the following.

[0098] With this configuration, it is possible to prevent the ceiling surface material 50 from falling off.

[0099] In addition, in ceiling structure 1, The structure further includes a reinforcing pipe 90 (pipe member) through which the hanging bolt 10 is inserted.

[0100] With this configuration, the strength of the suspension bolt 10 (for example, strength against compressive force in the axial direction) can be improved, and buckling of the suspension bolt 10 can be suppressed.

[0101] Also, in ceiling structure 1, The hanging bolt 10 is It is fixed to the first reinforcing metal fitting 70 (reinforcing member) via the reinforcing pipe 90 (pipe member) (see FIGS. 9 and 10).

[0102] This configuration prevents force from being directly transmitted from the first reinforcing metal fitting 70 to the suspension bolt 10, thereby effectively preventing the suspension bolt 10 from buckling.

[0103] Also, in ceiling structure 1, The first reinforcing metal fitting 70 (reinforcing member) is The first fixing portion (upper fixing piece 78 and lower fixing piece 79) for fixing the hanging bolt 10 is provided, The first fixing portion (upper fixing piece 78 and lower fixing piece 79) is The first reinforcing fitting 70 (reinforcing member) is integrally formed with a main body portion 71 and a claw portion 74 (second fixing portion) for fixing the sill support 30 (sill support member) and the brace 60.

[0104] This configuration allows the number of parts to be reduced, and workability to be improved.

[0105] In addition, in ceiling structure 1, The apparatus further includes fixing members (first mounting hardware 110 and second mounting hardware 210) for fixing the first reinforcing metal fitting 70 (reinforcing member) and the suspension bolt 10 together.

[0106] With this configuration, for an existing ceiling structure to which a first reinforcing bracket (for example, one that does not have an upper end extension portion 72 or a lower end extension portion 73) is attached, the first mounting bracket 110 and the second mounting bracket 210 can be used to fix the hanging bolt to the first reinforcing bracket, and thus the ceiling structure 1 of this embodiment can be adopted.

[0107] Also, in ceiling structure 1, The hanging bolt 10 is In addition to the first reinforcing metal fitting 70 (reinforcing member), the soffit support 30 (soffit support member) is supported via a hanger 20 fixed to the lower end of the hanging bolt 10, The second mounting hardware 210 (fixing member) is It is provided above the hanger 20 (see FIGS. 9 and 10).

[0108] With this configuration, the hanger 20 can be used to more effectively prevent the ceiling surface material 50 from falling off.

[0109] Also, in ceiling structure 1, One brace 60 is provided, One brace 60 and one hanging bolt 10 are They are arranged side by side in a direction along the longitudinal direction of the sill support 30 (sill support member), and are spaced apart from each other in the longitudinal direction as they go upward.

[0110] With this configuration, even with a single brace 60 rather than the typical pair (two) of braces, it is possible to prevent the ceiling surface material 50 from falling off. That is, for example, if a pair of braces were installed, it may interfere with other equipment, or it may not be possible to install a pair (two) of braces in a narrow space such as the eaves. In such cases, if only one brace is installed, when the ceiling surface material 50 shakes during an earthquake, for example, the horizontal force generated in the ceiling surface material 50 cannot be smoothly transmitted.

[0111] However, in the ceiling structure 1 according to this embodiment, the hanging bolt 10 is fixed to the first reinforcing metal fitting, and therefore the hanging bolt 10 can function as a pair (two) of braces together with the brace 60. With this configuration, the ceiling structure 1 can prevent the ceiling surface material 50 from falling off.

[0112] The first reinforcing metal fitting 70 is one embodiment of an inter-brace reinforcing member. The second reinforcing metal fitting 80 is an embodiment of a fixed reinforcing member. The siding support 30 is one embodiment of a siding support member. Moreover, the furring strip support member 130 is one embodiment of a furring strip support member. The reinforcing pipe 90 is an embodiment of a pipe member.

[0113] Although one embodiment has been described above, the present invention is not limited to the above configuration, and various modifications are possible within the scope of the invention described in the claims.

[0114] For example, in this embodiment, the sill 40 is a single sill, but it may also be a double sill that is wider than a single sill.

[0115] Furthermore, in this embodiment, one brace 60 is provided for each first reinforcing metal fitting 70, but this is not limiting. That is, a pair (two) of braces 60 formed symmetrically to each other in the horizontal direction may also be provided. This can further prevent the ceiling surface material 50 from falling off in the event of an earthquake, for example.

[0116] Furthermore, the configuration of the first reinforcing metal fitting 70 is not limited to that according to this embodiment. For example, the size and shape of the first reinforcing metal fitting 70 can be modified as appropriate. Furthermore, although the claw portions 74 of the first reinforcing metal fitting 70 are configured to abut against the second reinforcing metal fitting 80 from the sides, they may also abut from above, or from above and the sides.

[0117] Furthermore, the configuration of the upper fixing piece 78 of the first reinforcing bracket 70 according to the first embodiment is not limited to that according to the present embodiment. For example, in the ceiling structure 1 according to the sixth embodiment shown in Figures 15(a) to 15(c), the upper fixing piece 780 of the first reinforcing bracket 70 includes a first portion 781 and a second portion 782.

[0118] The first portion 781 extends forward from the center of the left and right sides of the upper end of the main body 71. The first portion 781 is formed in a generally rectangular flat plate shape in a plan view. A first notch 781a is formed in the first portion, cut from the front to the rear. The left-right width of the first notch 781a is formed to be generally the same as the outer diameter of the hanging bolt 10.

[0119] The second portion 782 is a member formed separately from the first portion 781. The second portion 782 is formed by bending upper and lower intermediate portions of a generally plate-shaped member, to provide an upper portion (second upper portion 783) and a lower portion (second lower portion 784) that extend rearward. The second upper portion 783 and the second lower portion 784 are provided with a gap between them in the vertical direction. The second upper portion 783 and the second lower portion 784 each have a second notch 782a cut out from rear to front. The left-right width of the second notch 782a is formed to be approximately the same as the outer diameter of the hanging bolt 10.

[0120] In this way, the second portion 782 is attached to the first portion 781, and the upper fixing piece 780 is formed by fixing them to each other. Specifically, as shown in FIG. 15(b), the upper fixing piece 780 is formed by fitting the first portion 781 into the gap between the second upper portion 783 and the second lower portion 784 of the second portion 782 and fixing them to each other using any fixing means such as screws. Accordingly, as shown in FIG. 15(c), the innermost (rearmost) portion of the first notch 781a of the first portion 781 and the innermost (frontmost) portion of the second notch 782a of the second portion 782 overlap in the vertical direction, thereby forming a through hole (upper through hole 780a) that penetrates in the vertical direction. In this way, the upper through hole 780a is configured to allow the suspension bolt 10 to be inserted therethrough, similar to the upper through hole 78a according to the first embodiment.

[0121] In Figure 15, an alternative embodiment of the upper fixed piece 78 of the first reinforcing bracket 70 according to the first embodiment has been described, but a similar configuration (alternative embodiment) can also be adopted for the lower fixed piece 79 of the first reinforcing bracket 70 according to the first embodiment.

[0122] Furthermore, the configuration of the second reinforcing metal fitting 80 is not limited to that according to this embodiment. For example, the size and shape of the second reinforcing metal fitting 80 can be changed as appropriate.

[0123] Furthermore, the second reinforcing metal fitting 80 does not necessarily have to be provided. Furthermore, the reinforcing pipe 90 does not necessarily have to be provided. Furthermore, the reinforcing pipe 90 (pipe member) may be formed from a plurality of members, rather than from a single member as in this embodiment. Specifically, the reinforcing pipe 90 (pipe member) may be formed by combining two elongated members, such as channel bars, that are U-shaped when viewed in the longitudinal direction.

[0124] Although the furring strip support member according to the present invention is provided with the furring strip support 30, it is not limited to this. That is, the furring strip support member may be a member (furring strip support member) arranged above the furring strip support 30 with its longitudinal direction perpendicular to the longitudinal direction of the furring strip support 30.

[0125] Furthermore, the configurations of the first, second, third, fourth, fifth, and sixth embodiments can be used in any combination. For example, a hanger 20 can be fixed to the lower end of the suspension bolt 10 according to the first and second embodiments (below the portion where the suspension bolt 10 is fixed to the first reinforcing metal fitting 70). Furthermore, the first mounting bracket 110 according to the second embodiment can be fixed to the suspension bolt 10 via a reinforcing pipe 90. [Explanation of symbols]
