Description

[Technical field]

[0001] The present invention relates to building walls and buildings. [Background technology]

[0002] Patent Document 1 discloses a support structure for a shutter device. The shutter device is attached to a hanging wall of a building by a bracket. Specifically, the bracket is disposed between the wall surface of the hanging wall and the shutter device. The shutter device is fixed to the hanging wall by a screw penetrating a part of the shutter device and the bracket. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2015-94141 A Summary of the Invention [Problem to be solved by the invention]

[0004] The wall surface of the hanging wall on which the bracket is placed is a design surface and may have an uneven shape. In this case, the bracket may not be stably attached to the predetermined position on the wall surface of the hanging wall, and the shutter device may not be stably attached to the hanging wall. [Means for solving the problem]

[0005] (1) A wall of a building that solves the above-mentioned problems is a wall of a building to which a shutter device is attached by a bracket, and comprises a frame fixed to a main body, a reinforcing member fixed to the frame, an exterior wall panel arranged so that a first wall surface faces the reinforcing member, and a fixing panel arranged on a second wall surface of the exterior wall panel, which is the surface opposite to the first wall surface, wherein the fixing panel has a first surface facing the exterior wall panel and a second surface which is the surface opposite to the first surface, the second surface includes a positioning surface on which the bracket is positioned, the positioning surface is a flat surface, and the bracket is fixed to the reinforcing member by a fastening member that penetrates the exterior wall panel and the fixing panel.

[0006] According to this configuration, the fixing panel is disposed between the exterior wall panel and the bracket. The mounting surface of the fixing panel on which the bracket is disposed is a flat surface. Therefore, even if the second wall surface of the exterior wall panel has an uneven shape, the bracket is disposed on the flat surface. Therefore, the shutter device can be stably attached.

[0007] (2) In the wall of the building described in (1) above, a hook is provided on the second surface of the fixing panel, and a loosening prevention member is hooked onto the hook, and the loosening prevention member has a support portion that is hung on the hook and an engagement portion that engages with the head of the fastening member.

[0008] According to this configuration, the loosening prevention member is hooked onto the hook, and the engagement portion of the loosening prevention member engages with the head of the fastening member. Therefore, even if the fastening member is subjected to vibrations caused by opening and closing the shutter device for many years, the fastening member is unlikely to loosen. Therefore, the bracket, the fixed panel, and the exterior wall panel can be stably fixed to the reinforcing member. In addition, since the support portion of the loosening prevention member is sandwiched between the second surface of the fixed panel and the hook, the loosening prevention member is unlikely to come off the fixed panel even if the shutter device vibrates when opening and closing.

[0009] (3) A wall of the building described in (1) or (2) above includes a first exterior wall panel as the exterior wall panel, a second exterior wall panel as the exterior wall panel adhered to the first exterior wall panel by a joint material, a first fixing panel as the fixing panel arranged on the second surface of the first exterior wall panel and having a first bracket as the bracket arranged on its arrangement surface, and a second fixing panel as the fixing panel arranged on the second surface of the second exterior wall panel and having a second bracket as the bracket arranged on its arrangement surface, and the joint material is exposed from a gap between the first fixing panel and the second fixing panel. With this configuration, the joint material is not hidden by the fixed panel, making maintenance of the joint material easy.

[0010] (4) In the wall of the building described in (3) above, the shutter device comprises a pair of guide rails, a curtain that opens and closes an opening of the storage space by moving along the pair of guide rails, and an auxiliary mechanism that assists the movement of the curtain, wherein the auxiliary mechanism has a rotating shaft, a pair of drums connected to both ends of the rotating shaft and rotating integrally with the rotating shaft, a pair of wires that are wound around the pair of drums and have ends connected to the curtain, a first coil spring through which the rotating shaft is inserted, and a second coil spring through which the rotating shaft is inserted, wherein a first end of the first coil spring is connected to the first bracket, a second end of the first coil spring is connected to the rotating shaft, a first end of the second coil spring is connected to the second bracket, and a second end of the second coil spring is connected to the rotating shaft.

[0011] According to this configuration, when the opening of the storage space is changed from an open state to a closed state, the pair of wires are paid out from the pair of drums due to the weight of the curtain, causing the pair of drums to rotate. When the pair of drums rotate, the rotation shaft also rotates.

[0012] A first end of the first coil spring is connected to the first bracket. A second end of the first coil spring is connected to the rotating shaft. Therefore, when the rotating shaft rotates, the first coil spring is twisted. At this time, the first coil spring exerts a force on the first bracket in a direction away from the first exterior wall panel.

[0013] The first bracket is connected to the reinforcing member via the first fixing panel and the fastening member. The force acting on the first bracket is applied to the reinforcing member and the frame connected to the reinforcing member, so the force applied to the first exterior wall panel is small. Therefore, the first exterior wall panel is less likely to be lifted up.

[0014] Similarly, a first end of the second coil spring is connected to the second bracket. A second end of the second coil spring is connected to the rotating shaft. Therefore, when the rotating shaft rotates, the second coil spring is twisted. At this time, the second coil spring exerts a force on the second bracket in a direction away from the second exterior wall panel.

[0015] The second bracket is connected to the reinforcing member via the second fixing panel and the fastening member. The force acting on the second bracket is applied to the reinforcing member and the frame connected to the reinforcing member, so the force applied to the second exterior wall panel is reduced. Therefore, the second exterior wall panel is less likely to be lifted up.

[0016] (5) In the wall of the building described above in (4), the fixed panel is fixed to the frame by additional fastening members that penetrate the exterior wall panel. According to this configuration, the fixed panel is not only fixed to the reinforcing member by the fastening member, but also fixed to the frame by the additional fastening member. This makes the fixed panel more firmly fixed. Therefore, the exterior wall panel is less likely to be turned up.

[0017] (6) In a wall of any one of the buildings (1) to (5) above, the reinforcing member has a bolt insertion hole through which a bolt serving as the fastening member is inserted, and a nut is fixed to surround the bolt insertion hole, and the bracket, the fixing panel, the exterior wall panel, and the reinforcing member are fastened together by screwing the bolt into the nut.

[0018] One method for fixing the bracket, the fixing panel, and the exterior wall panel to the reinforcing member is, for example, to fix the bracket, the fixing panel, and the exterior wall panel to the reinforcing member with screws. However, in this case, when the screws are removed to replace the shutter device or the bracket, the areas around the screw holes in the fixing panel and the reinforcing member deteriorate, and the fixing panel and the reinforcing member must also be replaced.

[0019] In contrast, according to the above-mentioned configuration, the bolt is inserted into the bolt insertion hole of the reinforcing member and screwed into the nut fixed to the reinforcing member, thereby fastening the bracket, the fixing panel, the exterior wall panel, and the reinforcing member together. In this case, even if the bolt is removed to replace the shutter device or the bracket, it is not necessary to replace the fixing panel and the reinforcing member.

[0020] (7) A building that solves the above problem is a building comprising a wall and a shutter device, the shutter device being attached to the wall by a bracket, and the wall being a wall of a building described in any one of (1) to (6) above.

[0021] According to this configuration, the fixing panel is disposed between the exterior wall panel and the bracket. The mounting surface of the fixing panel on which the bracket is disposed is a flat surface. Therefore, even if the second wall surface of the exterior wall panel has an uneven shape, the bracket is disposed on the flat surface. Therefore, the shutter device can be stably attached. Effect of the Invention

[0022] According to the building wall and building of the present invention, a shutter device can be stably attached. [Brief description of the drawings]

[0024] A wall 12 of a building 10 and the building 10 of this embodiment will be described with reference to Figures 1 to 6. The building 10 of this embodiment is a garage. As shown in FIG. 1, a building 10 includes a hanging wall 24 as a wall 12 and a shutter device 13.

[0025] The building 10 includes a ceiling 20, a first side wall 21, a second side wall 22, and a third side wall (not shown). The first side wall 21 and the second side wall 22 face each other. The third side wall connects the first side wall 21 and the second side wall 22. The ceiling 20, the first side wall 21, the second side wall 22, and the third side wall define a storage space 23 in which a parked vehicle is stored. The storage space 23 has an opening 23a that communicates with the outdoors. The hanging wall 24 hangs down from a portion of the ceiling 20 located at the opening 23a. The shutter device 13 opens and closes the opening 23a. The shutter device 13 is attached to the hanging wall 24 by a bracket 14.

[0026] <Shutter device> The shutter device 13 of this embodiment is of an overslider type. The shutter device 13 has a pair of guide rails 31, a curtain 32 that opens and closes the opening 23a by moving along the pair of guide rails 31, and an auxiliary mechanism 33 that assists the movement of the curtain 32. The shutter device 13 may be of a motor-driven type or a manual type. The shutter device 13 of this embodiment is of a manual type.

[0027] Each guide rail 31 has a vertical rail 31a extending vertically, a horizontal rail 31b extending in the depth direction of the storage space 23, and a connecting rail 31c connecting the vertical rail 31a and the horizontal rail 31b in an arc shape. One guide rail 31 is fixed to the first side wall 21, and the other guide rail 31 is fixed to the second side wall 22.

[0028] The curtain 32 is configured by connecting a plurality of curtain panels 32a. The curtain 32 is attached movably to the guide rail 31 by a roller bracket or the like (not shown). The opening 23a is opened and closed by the movement of the curtain 32 along the guide rail 31.

[0029] 1, when the curtain 32 is positioned on the vertical rail 31a, the opening 23a is blocked by the curtain 32. Therefore, the opening 23a is in a closed state. Although not shown, when the curtain 32 is positioned on the horizontal rail 31b, the opening 23a is not blocked by the curtain 32. Therefore, the opening 23a is in an open state.

[0030] The auxiliary mechanism 33 has a rotating shaft 34, a pair of drums 35, a pair of wires 36, a first coil spring 37, and a second coil spring 38. The rotating shaft 34 in this embodiment has a first shaft member 34a, a second shaft member 34b, and a connecting member 34c that connects the first shaft member 34a and the second shaft member 34b. The pair of drums 35 are connected to both ends of the rotating shaft 34. The pair of drums 35 rotate integrally with the rotating shaft 34. The pair of wires 36 are wound around the pair of drums 35. The ends of the pair of wires 36 are connected to both ends in the width direction of the curtain panel 32a that is located at the lowest side among the multiple curtain panels 32a when the curtain 32 is located on the vertical rail 31a. The rotating shaft 34 is inserted through the first coil spring 37 and the second coil spring 38. In this embodiment, the first shaft member 34a is inserted through the first coil spring 37. The second shaft member 34b has a second coil spring 38 inserted therethrough.

[0031] The first shaft member 34a is attached to the hanging wall 24 by a first inner bracket 14a and a first outer bracket 14b as the bracket 14. The first inner bracket 14a and the first outer bracket 14b rotatably support the first shaft member 34a. The second shaft member 34b is attached to the hanging wall 24 by a second inner bracket 14c and a second outer bracket 14d as the bracket 14. The second inner bracket 14c and the second outer bracket 14d rotatably support the second shaft member 34b. The pair of drums 35 are attached to the hanging wall 24 by drum brackets 14e as the bracket 14. The drum brackets 14e rotatably support the drums 35.

[0032] 2 and 3, the second inner bracket 14c of this embodiment has a structure that is plane-symmetrical to the first inner bracket 14a. The first inner bracket 14a and the second inner bracket 14c are each L-shaped and have a flat first plate portion 41 and a flat second plate portion 42 that is perpendicular to the first plate portion 41.

[0033] 3, two plate through holes 41a are provided in the first plate portion 41. The plate through holes 41a penetrate the first plate portion 41 in the plate thickness direction. 2, the second plate portion 42 is provided with a shaft insertion hole 42a through which the rotating shaft 34 is inserted. The shaft insertion hole 42a is a through-hole that penetrates the second plate portion 42 in the plate thickness direction.

[0034] As shown in FIG. 4, the first inner bracket 14a is located between the connecting member 34c and the first coil spring 37 in the axial direction of the rotating shaft 34. The first outer bracket 14b is located on the opposite side of the first inner bracket 14a across the first coil spring 37 in the axial direction of the rotating shaft 34. A first end of the first coil spring 37 is connected to a first inner connecting member 15a connected to the first inner bracket 14a as the first bracket. Therefore, the first end of the first coil spring 37 is indirectly connected to the first inner bracket 14a. A second end of the first coil spring 37 is connected to a first outer connecting member 15b connected to the rotating shaft 34. Therefore, the second end of the first coil spring 37 is indirectly connected to the rotating shaft 34.

[0035] The second inner bracket 14c is located between the connecting member 34c and the second coil spring 38 in the axial direction of the rotating shaft 34. The second outer bracket 14d is located on the opposite side of the second inner bracket 14c across the second coil spring 38 in the axial direction of the rotating shaft 34. A first end of the second coil spring 38 is connected to a second inner connecting member 15c connected to the second inner bracket 14c as a second bracket. Therefore, the first end of the second coil spring 38 is indirectly connected to the second inner bracket 14c. A second end of the second coil spring 38 is connected to a second outer connecting member 15d connected to the rotating shaft 34. Therefore, the second end of the second coil spring 38 is indirectly connected to the rotating shaft 34.

[0036] When opening 23a is changed from an open state to a closed state, curtain 32 is lowered. Curtain 32 lowers by its own weight. At this time, wire 36 is paid out from drum 35, causing drum 35 to rotate in a first direction, and rotating shaft 34 also rotates in the first direction together with drum 35. As a result, first coil spring 37 and second coil spring 38 are twisted, and elastic energy is accumulated.

[0037] On the other hand, when the opening 23a is changed from the closed state to the open state, the curtain 32 is raised. At this time, the first shaft member 34a rotates in the second direction due to the elastic energy of the first coil spring 37 that has been accumulated. Also, the second shaft member 34b rotates in the second direction due to the elastic energy of the second coil spring 38 that has been accumulated. When the rotating shaft 34 rotates in the second direction, the drum 35 also rotates in the second direction. As a result, the wire 36 is wound up on the drum 35, and an upward force acts on the curtain 32. In this way, the elastic forces of the first coil spring 37 and the second coil spring 38 assist the rise of the curtain 32.

[0038] <Dropped wall> As shown in Figs. 1 and 4, the hanging wall 24 is composed of first to fourth hanging wall constituent parts 24a to 24d. The first hanging wall constituent parts 24a to 24d are aligned in the direction in which the first side wall 21 and the second side wall 22 face each other. The first hanging wall constituent part 24a and the second hanging wall constituent part 24b are aligned. The third hanging wall constituent part 24c is located on the opposite side to the second hanging wall constituent part 24b across the first hanging wall constituent part 24a. The fourth hanging wall constituent part 24d is located on the opposite side to the first hanging wall constituent part 24a across the second hanging wall constituent part 24b.

The beam 11 is, for example, an H-shaped steel. The beam 11 has an upper flange 11a, a web 11b, and a lower flange 11c. The lower flange 11c has an inner portion 111 located closer to the storage space 23 than the web 11b, and an outer portion 112 located outside than the web 11b. The frame 51 is fixed to the lower flange 11c of the beam 11 by a frame fixing bolt B. In this embodiment, the frame 51 is fixed to each of the inner portion 111 and the outer portion 112 of the lower flange 11c. That is, the frame 51 is provided in a double manner in the depth direction of the storage space 23.

The reinforcing member 52 is made of iron. The reinforcing member 52 is fixed to the frame 51. The reinforcing member 52 is disposed between a pair of vertical frame parts 512. When the frame 51 has an additional frame part, the reinforcing member 52 is disposed between one vertical frame part 512 and the additional frame part, and between the other vertical frame part 512 and the additional frame part. The reinforcing member 52 has an inner surface 521 and an outer surface 522. The inner surface 521 and the outer surface 522 are surfaces perpendicular to the plate thickness direction of the reinforcing member 52. The inner surface 521 is located on the storage space 23 side. The outer surface 522 is a surface opposite to the inner surface 521. The outer surface 522 is located on the outdoor side. The reinforcing member 52 has two reinforcing member through holes 523. The two reinforcing member through holes 523 are arranged side by side with a gap therebetween in the up-down direction.

The first wall surface 531 and the second wall surface 532 are surfaces perpendicular to the plate thickness direction of the exterior wall panel 53. The second wall surface 532 is a surface opposite to the first wall surface 531. The first wall surface 531 of the inner panel 61 is a surface facing the inner surface 521 of the reinforcing member 52 (see FIG. 3). The second wall surface 532 of the inner panel 61 is a surface exposed in the storage space 23. The second wall surface 532 of the inner panel 61 is a design surface. The first wall surface 531 of the outer panel 62 is a surface facing the outer surface 522 of the reinforcing member 52. The second wall surface 532 of the outer panel 62 is a surface exposed to the outdoors. The second wall surface 532 of the outer panel 62 is a design surface.

[0049] As shown in Fig. 5, the first exterior wall panel 53a and the second exterior wall panel 53b each have two first panel through holes 533 and two second panel through holes 534. Each of the first panel through holes 533 and each of the second panel through holes 534 penetrates the inner panel 61 in the plate thickness direction. The two first panel through holes 533 are arranged at an interval in the up-down direction. The two second panel through holes 534 are arranged at an interval in the up-down direction. The two first panel through holes 533 and the two second panel through holes 534 are arranged at an interval in the extension direction of the beam 11.

Therefore, the inner bottom surface of the recess 56 includes an arrangement surface 56a on which the bracket 14 is disposed. As described above, the inner bottom surface of the recess 56 is a flat surface. Therefore, the arrangement surface 56a is a flat surface.

[0059] In this embodiment, the first inner bracket 14a is disposed on the arrangement surface 56a of the first fixed panel 54a. The first plate portion 41 of the first inner bracket 14a is disposed along the arrangement surface 56a of the first fixed panel 54a. The plate through hole 41a of the first inner bracket 14a communicates with the first through hole 543 of the first fixed panel 54a.

[0060] The second inner bracket 14c is disposed on the arrangement surface 56a of the second fixed panel 54b. The first plate portion 41 of the second inner bracket 14c is disposed along the arrangement surface 56a of the second fixed panel 54b. The plate through hole 41a of the second inner bracket 14c communicates with the first through hole 543 of the second fixed panel 54b.

[0061] As shown in FIG. 6, the fixed panel 54 is provided with a hook 70a and an additional hook 70b. The hook 70a is located above the two first through holes 543. The additional hook 70b is located above the two second through holes 544. The hook 70a and the additional hook 70b are each L-shaped having a first portion 71 extending from the second surface 542 of the fixed panel 54 and a second portion 72 extending from the tip of the first portion 71. The second portion 72 of the hook 70a extends from the tip of the first portion 71 in a direction away from the first through hole 543, i.e., upward. The second portion 72 of the additional hook 70b extends from the tip of the first portion 71 in a direction away from the second through hole 544, i.e., upward.

[0062] A loosening-inhibiting member 80a is hooked onto the hook 70a. An additional loosening-inhibiting member 80b is hooked onto the additional hook 70b. Note that Fig. 6 shows a state in which the loosening-inhibiting member 80a is hooked onto the hook 70a of the first fixed panel 54a, and a state in which the loosening-inhibiting member 80a is not hooked onto the hook 70a of the second fixed panel 54b. Fig. 6 also shows a state in which the additional loosening-inhibiting member 80b is hooked onto the additional hook 70b of the first fixed panel 54a, and a state in which the additional loosening-inhibiting member 80b is not hooked onto the additional hook 70b of the second fixed panel 54b.

[0063] The loosening suppression member 80a of this embodiment is U-shaped. The loosening suppression member 80a has a support portion 81 that is hung on the hook 70a, and an engagement portion 82 that engages with a bolt B1 serving as a fastening member, which will be described later. The support portion 81 is sandwiched between the second surface 542 of the fixing panel 54 and the second portion 72 of the hook 70a. The engagement portion 82 of this embodiment is formed by a pair of extension portions 82a that extend from the support portion 81 and are spaced apart from each other.

[0064] The additional loosening suppression member 80b of this embodiment is U-shaped. The additional loosening suppression member 80b has a support portion 81 that is hooked onto the additional hook 70b, and an engagement portion 82 that engages with an additional bolt B2, which serves as an additional fastening bolt described below. The support portion 81 is sandwiched between the second surface 542 of the fixing panel 54 and the second portion 72 of the additional hook 70b. The engagement portion 82 of this embodiment is formed by a pair of extension portions 82a that extend from the support portion 81 and are arranged at a distance from each other.

[0065] As shown in Fig. 3, the bolt B1 is inserted through the plate through hole 41a of the first inner bracket 14a, the first through hole 543 of the first fixing panel 54a, the first panel through hole 533 of the first outer wall panel 53a, and the reinforcing member through hole 523 of the first reinforcing member 52a. That is, the shaft portion B11 of the bolt B1 penetrates the first inner bracket 14a, the first fixing panel 54a, the first outer wall panel 53a, and the first reinforcing member 52a. The reinforcing member through hole 523 is a bolt insertion hole through which the bolt B1 is inserted. The bolt B1 is screwed into a nut N1 fixed to the first reinforcing member 52a.

[0066] In this manner, the first inner bracket 14a, the first fixing panel 54a, the first outer wall panel 53a, and the first reinforcing member 52a are fastened together by screwing the bolt B1 into the nut N1. Therefore, the first inner bracket 14a is fixed to the first reinforcing member 52a by the bolt B1 that penetrates the first fixing panel 54a and the first outer wall panel 53a.

[0067] The bolt B1 in this embodiment is a hexagonal bolt. The engagement portion 82 of the loosening suppression member 80a hooked on the hook 70a of the first fixing panel 54a engages with the head B12 of the upper bolt B1 of the two bolts B1 arranged vertically. Specifically, the head B12 of the bolt B1 is sandwiched between a pair of extension portions 82a of the loosening suppression member 80a.

[0068] The bolt B1 is inserted through the plate through-hole 41a of the second inner bracket 14c, the first through-hole 543 of the second fixing panel 54b, the first panel through-hole 533 of the second outer wall panel 53b, and the reinforcing member through-hole 523 of the second reinforcing member 52b. That is, the shaft portion B11 of the bolt B1 penetrates the second inner bracket 14c, the second fixing panel 54b, the second outer wall panel 53b, and the second reinforcing member 52b. The reinforcing member through-hole 523 is a bolt insertion hole through which the bolt B1 is inserted. The bolt B1 is screwed into a nut N1 fixed to the second reinforcing member 52b.

[0069] In this manner, the second inner bracket 14c, the second fixing panel 54b, the second outer wall panel 53b, and the second reinforcing member 52b are fastened together by screwing the bolt B1 into the nut N1. Therefore, the second inner bracket 14c is fixed to the second reinforcing member 52b by the bolt B1 that penetrates the second fixing panel 54b and the second outer wall panel 53b.

[0070] The bolt B1 in this embodiment is a hexagonal bolt. The engagement portion 82 of the loosening suppression member 80a hooked on the hook 70a of the second fixing panel 54b engages with the head B12 of the upper bolt B1 of the two bolts B1 arranged vertically. Specifically, the head B12 of the bolt B1 is sandwiched between a pair of extension portions 82a of the loosening suppression member 80a.

[0071] The additional bolt B2 is inserted through the second through-hole 544 of the first fixing panel 54a, the second panel through-hole 534 of the first exterior wall panel 53a, and the frame through-hole 513 of the first frame 51a. That is, the shaft portion B21 of the additional bolt B2 penetrates the first fixing panel 54a, the first exterior wall panel 53a, and the first frame 51a. The additional bolt B2 is screwed into an additional nut N2 fixed to the first frame 51a.

[0072] In this manner, the first fixing panel 54a, the first exterior wall panel 53a, and the first frame 51a are fastened together by screwing the additional bolt B2 into the additional nut N2. Therefore, the first fixing panel 54a is fixed to the first frame 51a by the additional bolt B2 penetrating the first exterior wall panel 53a.

[0073] The additional bolt B2 in this embodiment is a hexagonal bolt. The engagement portion 82 of the additional loosening prevention member 80b hooked on the additional hook 70b of the first fixing panel 54a engages with the head B22 of the upper additional bolt B2 of the two additional bolts B2 arranged vertically. Specifically, the head B22 of the additional bolt B2 is sandwiched between a pair of extension portions 82a of the additional loosening prevention member 80b.

[0074] The additional bolt B2 is inserted through the second through hole 544 of the second fixing panel 54b, the second panel through hole 534 of the second exterior wall panel 53b, and the frame through hole 513 of the second frame 51b. That is, the shaft portion B21 of the additional bolt B2 penetrates the second fixing panel 54b, the second exterior wall panel 53b, and the second frame 51b. The additional bolt B2 is screwed into an additional nut N2 fixed to the second frame 51b.

[0075] In this manner, the second fixing panel 54b, the second exterior wall panel 53b, and the second frame 51b are fastened together by screwing the additional bolt B2 into the additional nut N2. Therefore, the second fixing panel 54b is fixed to the second frame 51b by the additional bolt B2 penetrating the second exterior wall panel 53b.

[0076] The additional bolt B2 in this embodiment is a hexagonal bolt. The engagement portion 82 of the additional loosening prevention member 80b hooked on the additional hook 70b of the second fixing panel 54b engages with the head B22 of the upper additional bolt B2 of the two additional bolts B2 arranged vertically. Specifically, the head B22 of the additional bolt B2 is sandwiched between a pair of extension portions 82a of the additional loosening prevention member 80b.

[0077] [Operation of this embodiment] The operation of this embodiment will now be described. The hanging wall 24 of the building 10 includes a frame 51, a reinforcing member 52, an exterior wall panel 53, and a fixed panel 54. The frame 51 is fixed to the beam 11. The reinforcing member 52 is fixed to the frame 51. The exterior wall panel 53 is disposed so that a first wall surface 531 faces the reinforcing member 52. The fixed panel 54 is disposed on a second wall surface 532 of the exterior wall panel 53. The fixed panel 54 has a first surface 541 facing the exterior wall panel 53, and a second surface 542 that is the surface opposite to the first surface 541. The second surface 542 of the fixed panel 54 includes an arrangement surface 56a on which the bracket 14 is arranged. The arrangement surface 56a is a flat surface. The bracket 14 is fixed to the reinforcing member 52 by a bolt B1 that penetrates the exterior wall panel 53 and the fixed panel 54.

[0078] The second wall surface 532 of the exterior wall panel 53 is a design surface. Therefore, the second wall surface 532 may have an uneven shape. In this embodiment, the fixed panel 54 is disposed between the exterior wall panel 53 and the bracket 14. The arrangement surface 56a on which the bracket 14 is disposed in the fixed panel 54 is a flat surface. As a result, even if the second wall surface 532 has an uneven shape, the bracket 14 is disposed on the flat surface. Therefore, the shutter device 13 can be stably attached.

[0079] [Effects of this embodiment] The effects of this embodiment will be described. (1) The fixed panel 54 is disposed on the second wall surface 532 of the exterior wall panel 53. The second surface 542 of the fixed panel 54 includes an arrangement surface 56a on which the bracket 14 is disposed. The arrangement surface 56a is a flat surface. As a result, even if the second wall surface 532 has an uneven shape, the bracket 14 is disposed on the flat surface. Therefore, the shutter device 13 can be stably attached.

[0080] (2) A hook 70a is provided on the second surface 542 of the fixing panel 54. A loosening prevention member 80a is hooked onto the hook 70a. The loosening prevention member 80a has a support portion 81 that is hooked onto the hook 70a and an engagement portion 82 that engages with the head portion B12 of the bolt B1.

[0081] According to this configuration, the loosening suppression member 80a is hooked on the hook 70a, and the engagement portion 82 of the loosening suppression member 80a engages with the head B12 of the bolt B1. Therefore, even if the bolt B1 is subjected to vibrations during opening and closing of the shutter device 13 for many years, the bolt B1 is unlikely to loosen. Therefore, the bracket 14, the fixed panel 54, and the exterior wall panel 53 can be stably fixed to the reinforcing member 52. In addition, since the support portion 81 of the loosening suppression member 80a is sandwiched between the second surface 542 of the fixed panel 54 and the hook 70a, the loosening suppression member 80a is unlikely to come off the fixed panel 54 even if the shutter device 13 vibrates during opening and closing.

[0082] Further, an additional hook 70b is provided on the second surface 542 of the fixing panel 54. An additional loosening prevention member 80b is hooked onto the additional hook 70b. The additional loosening prevention member 80b has a support portion 81 that is hooked onto the additional hook 70b, and an engagement portion 82 that engages with the head portion B22 of the additional bolt B2.

[0083] According to this configuration, the additional loosening suppression member 80b is hooked on the additional hook 70b, and the engagement portion 82 of the additional loosening suppression member 80b engages with the head B22 of the additional bolt B2. Therefore, even if the additional bolt B2 is subjected to vibrations during opening and closing of the shutter device 13 for many years, the additional bolt B2 is unlikely to loosen. Therefore, the fixed panel 54 and the exterior wall panel 53 can be stably fixed to the frame 51. In addition, since the support portion 81 of the additional loosening suppression member 80b is sandwiched between the second surface 542 of the fixed panel 54 and the additional hook 70b, the additional loosening suppression member 80b is unlikely to come off the fixed panel 54 even if the shutter device 13 vibrates during opening and closing.

[0084] (3) The hanging wall 24 includes a first exterior wall panel 53a and a second exterior wall panel 53b as the exterior wall panels 53. The second exterior wall panel 53b is bonded to the first exterior wall panel 53a by a joint material 55. The hanging wall 24 also includes a first fixing panel 54a and a second fixing panel 54b as the fixing panels 54. The first fixing panel 54a is disposed on the arrangement surface 56a of the first exterior wall panel 53a. The first inner bracket 14a is disposed on the arrangement surface 56a of the first fixing panel 54a. The second fixing panel 54b is disposed on the arrangement surface 56a of the second exterior wall panel 53b. The second inner bracket 14c is disposed on the arrangement surface 56a of the second fixing panel 54b. The joint material 55 is exposed from the gap between the first fixing panel 54a and the second fixing panel 54b. According to this configuration, the joint material 55 is not hidden by the fixed panel 54, making maintenance of the joint material 55 easy.

[0085] (4) The shutter device 13 includes a pair of guide rails 31, a curtain 32 that opens and closes the opening 23a of the storage space 23 by moving along the pair of guide rails 31, and an auxiliary mechanism 33 that assists the movement of the curtain 32. The auxiliary mechanism 33 includes a rotating shaft 34, a pair of drums 35, a pair of wires 36, a first coil spring 37, and a second coil spring 38. The pair of drums 35 are connected to both ends of the rotating shaft 34. The pair of drums 35 rotate integrally with the rotating shaft 34. The pair of wires 36 are wound around the pair of drums 35. The ends of the pair of wires 36 are connected to the curtain 32. The rotating shaft 34 is inserted through the first coil spring 37 and the second coil spring 38. The first end of the first coil spring 37 is connected to the first inner bracket 14a. The second end of the first coil spring 37 is connected to the rotating shaft 34. A first end of the second coil spring 38 is connected to the second inner bracket 14c. A second end of the second coil spring 38 is connected to the rotating shaft 34.

[0086] According to this configuration, when the opening 23a of the storage space 23 is changed from an open state to a closed state, the pair of wires 36 are paid out from the pair of drums 35 by the weight of the curtain 32, causing the pair of drums 35 to rotate. When the pair of drums 35 rotate, the rotating shaft 34 also rotates.

[0087] A first end of the first coil spring 37 is connected to the first inner bracket 14a. A second end of the first coil spring 37 is connected to the rotating shaft 34. Therefore, when the rotating shaft 34 rotates, the first coil spring 37 is twisted. At this time, a force is applied by the first coil spring 37 to the first inner bracket 14a in a direction away from the first exterior wall panel 53a.

[0088] The first inner bracket 14a is connected to the first reinforcing member 52a via the first fixing panel 54a and the bolt B1. The force acting on the first inner bracket 14a is applied to the first reinforcing member 52a and the first frame 51a connected to the first reinforcing member 52a, so the force applied to the first outer wall panel 53a is reduced. Therefore, the first outer wall panel 53a is less likely to be turned up.

[0089] Similarly, a first end of the second coil spring 38 is connected to the second inner bracket 14c. A second end of the second coil spring 38 is connected to the rotating shaft 34. Therefore, when the rotating shaft 34 rotates, the second coil spring 38 is twisted. At this time, a force is applied by the second coil spring 38 to the second inner bracket 14c in a direction away from the second exterior wall panel 53b.

[0090] The second inner bracket 14c is connected to the second reinforcing member 52b via the second fixing panel 54b and the bolt B1. The force acting on the second inner bracket 14c is applied to the second reinforcing member 52b and the second frame 51b connected to the second reinforcing member 52b, so the force applied to the second exterior wall panel 53b is reduced. Therefore, the second exterior wall panel 53b is less likely to be turned up.

[0091] (5) The fixed panel 54 is fixed to the frame 51 by the additional bolt B2 that penetrates the exterior wall panel 53. With this configuration, the fixed panel 54 is not only fixed to the reinforcing member 52 by the bolt B1, but also fixed to the frame 51 by the additional bolt B2. This makes the fixed panel 54 more firmly fixed. As a result, the exterior wall panel 53 is less likely to be turned up.

[0092] (6) As will be described later, one method of fixing the bracket 14, the fixed panel 54, and the exterior wall panel 53 to the reinforcing member 52 is to fix the bracket 14, the fixed panel 54, and the exterior wall panel 53 to the reinforcing member 52 with screws, for example. However, in this case, when the screws are removed to replace the shutter device 13 or the bracket 14, the areas around the screw holes in the fixed panel 54 and the reinforcing member 52 deteriorate, and the fixed panel 54 and the reinforcing member 52 must also be replaced.

[0093] In contrast, in this embodiment, the bolt B1 is inserted into the reinforcing member through hole 523 of the reinforcing member 52 and screwed into the nut N1 welded to the reinforcing member 52, thereby fastening the bracket 14, the fixed panel 54, the exterior wall panel 53, and the reinforcing member 52 together. In this case, even if the bolt B1 is removed to replace the shutter device 13 or the bracket 14, it is not necessary to replace the fixed panel 54 and the reinforcing member 52.

[0094] <Example of change> The above embodiment is an example of the form that the wall 12 of the building 10 and the building 10 can take, and is not intended to limit the form. The wall 12 of the building 10 and the building 10 can take a form different from the form exemplified in the above embodiment. Examples of such a form include a form in which a part of the configuration of the embodiment is replaced, changed, or omitted, or a form in which a new configuration is added to the embodiment. Modified examples of the embodiment are shown below.

[0095] The building 10 is not limited to a garage. The building 10 may be, for example, a warehouse. In the above embodiment, the hanging wall 24 is given as an example of the wall 12 to which the shutter device 13 is attached, but the wall 12 is not limited to the hanging wall 24. The wall 12 may be a wall including the ceiling 20, for example.

[0096] The structure to which the frame 51 is fixed is not limited to the beam 11. The shutter device 13 is not limited to the overslider type. The shutter device 13 may be a winding type in which the curtain 32 is wound around a rotating shaft 34.

[0097] The shutter device 13 may be of either a manual or an electric type. The vibration generated when the shutter device 13 is opened and closed is more likely to be large in an electric type than in a manual type. For this reason, when the shutter device 13 is of an electric type, the loosening suppression member 80a and the additional loosening suppression member 80b are particularly effective.

[0098] The rotating shaft 34 may be a single shaft member, or may be configured by connecting three or more shaft members with connecting members. The number of hanging wall constituent parts constituting the hanging wall 24 may be changed as appropriate.

[0099] The fixing panel 54 may be provided not only on the first exterior wall panel 53a to which the first inner bracket 14a is attached and on the second exterior wall panel 53b to which the second inner bracket 14c is attached, but also on the exterior wall panel 53 to which the other brackets 14 are attached. In this case, the shutter device 13 can be attached more stably.

[0100] The number of bolts B1 may be changed as appropriate. The number of additional bolts B2 may be changed as appropriate. The fixed panel 54 does not have to be fixed to the frame 51 by the additional bolts B2.

[0101] The hook 70a may be omitted. In this case, the loosening suppression member 80a that is hooked onto the hook 70a is also omitted. The additional hook 70b may be omitted. In this case, the additional loosening suppression member 80b that is hooked onto the additional hook 70b is also omitted.

[0102] The engagement portion 82 of the loosening prevention member 80a may engage not only with the head B12 of the upper bolt B1 of two bolts B1 aligned vertically, but also with the head B12 of the lower bolt B1.

[0103] Similarly, the engagement portion 82 of the additional loosening prevention member 80b may engage not only with the head B12 of the upper additional bolt B2 of two additional bolts B2 arranged in the vertical direction, but also with the head B12 of the lower additional bolt B2.

[0104] One fixed panel 54 may be disposed so as to span both the second wall surface 532 of the first exterior wall panel 53a and the second wall surface 532 of the second exterior wall panel 53b. In this case, the joint material 55 interposed between the first exterior wall panel 53a and the second exterior wall panel 53b is located on the back side of the fixed panel 54 and is therefore hidden by the fixed panel 54.

[0105] The first end of the first coil spring 37 may be directly connected to the first inner bracket 14a without using the first inner connecting member 15a. "The first end of the first coil spring 37 is connected to the first bracket" includes both the case where the first end of the first coil spring 37 is directly connected to the first bracket and the case where the first end of the first coil spring 37 is indirectly connected to the first bracket.

[0106] The second end of the first coil spring 37 may be directly connected to the rotating shaft 34 without using the first outer connecting member 15b. "The second end of the first coil spring 37 is connected to the rotating shaft 34" includes both the case where the second end of the first coil spring 37 is directly connected to the rotating shaft 34 and the case where the second end of the first coil spring 37 is indirectly connected to the rotating shaft 34.

[0107] The first end of the second coil spring 38 may be directly connected to the second inner bracket 14c without using the second inner connecting member 15c. "The first end of the second coil spring 38 is connected to the second bracket" includes both the case where the first end of the second coil spring 38 is directly connected to the second bracket and the case where the first end of the second coil spring 38 is indirectly connected to the second bracket.

[0108] The second end of the second coil spring 38 may be directly connected to the rotating shaft 34 without using the second outer connecting member 15d. "The second end of the second coil spring 38 is connected to the rotating shaft 34" includes both the case where the second end of the second coil spring 38 is directly connected to the rotating shaft 34 and the case where the second end of the second coil spring 38 is indirectly connected to the rotating shaft 34.

[0109] The fastening members for fastening the bracket 14, the fixing panel 54, and the exterior wall panel 53 to the reinforcing member 52 are not limited to the bolt B1. The bracket 14, the fixing panel 54, and the exterior wall panel 53 may be fastened to the reinforcing member 52 by, for example, a screw. That is, the fastening members may be a screw. In this case, the nut N1 is not necessary.

[0110] The reinforcing member 52 may be provided with a female threaded hole instead of the reinforcing member through hole 523. The bolt B1 is screwed into the female threaded hole. In this case, the nut N1 is not necessary. The additional fastening members for fastening the fixing panel 54 and the exterior wall panel 53 to the frame 51 are not limited to the additional bolts B2. The fixing panel 54 and the exterior wall panel 53 may be fastened to the frame 51 by, for example, screws. That is, the additional fastening members may be screws. In this case, the additional nuts N2 are not required.

[0111] The frame 51 may be provided with a female threaded hole instead of the frame through hole 513. The additional bolt B2 is screwed into the female threaded hole. In this case, the additional nut N2 is not required.

[0112] This specification discloses the following techniques.
