[0009] (Embodiment 1) (1) Overview The mounting structure of the panel 1 according to this embodiment includes the panel 1, a cross member 3, and a weight support 4 (see Figs. 1A and 1B). The cross member 3 is fixed to the building skeleton 2 and has a base 30 protruding from the building skeleton 2. The weight support 4 has a fixing member 41, a support member 42, and a height adjustment bolt 43. The fixing member 41 is fixed to the panel 1 and has a bolt holding portion 411 protruding rearward from the panel 1. The support member 42 is formed separately from the fixing member 41, has a bolt support portion 421, and is fixed by being hooked to the base 30. The bolt support portion 421 faces the bolt holding portion 411. The height adjustment bolt 43 is provided on the fixing member 41, passes through the bolt holding portion 411, and has a tip that abuts against the bolt support portion 421. The panel 1 is mounted to the cross member 3 by the weight support 4.

[0010] In the mounting structure of the panel 1 according to this embodiment, the support member 42 is hooked and fixed to the base portion 30, so there is no need to use a fixing method such as welding to fix the weight receiving device 4 to the cross member 3. This reduces the effort required to fix the weight receiving device 4 to the cross member 3, and the workability of the panel 1 is likely to improve.

[0011] In this embodiment, the fixing member 41 further has a fastening portion 412 that is fixed to the panel 1, and the support member 42 further has an attachment portion 422 that is sandwiched between the fastening portion 412 and the base portion 30. The support member 42 is not welded or screwed to the cross member 3. In this case, there is no need to perform fixing work such as welding and screwing on the support member 42, which reduces the effort required to fix the weight support 4 to the cross member 3 and tends to improve the workability of the panel 1.

[0012] Furthermore, this embodiment employs a unique joint-based locking (panel rotation) mechanism, which absorbs shaking during earthquakes and follows the deformation between the building floors.

[0013] (2)Details The mounting structure for the panel 1 according to this embodiment includes the panel 1, a cross member 3, and a weight support 4. Each component will be described in detail below, with the longitudinal direction of the cross member 3 defined as the left-right direction, the side where the panel 1 is located relative to the cross member 3 defined as the front, the opposite side defined as the rear, and the direction perpendicular to the left-right direction and the front-rear direction defined as the up-down direction.

[0014] <Panel> 1A, 1B, 2A, and 2B, the panel 1 is a panel that is attached in plurality to cross members 3 to form the exterior wall of a building. The panel 1 is a sandwich panel having a pair of metal skins 10, 11 and a core material 12 located between the pair of metal skins 10, 11.

[0015] The panel 1 has a rectangular plate shape when viewed from the front. The panel 1 has a longitudinal direction parallel to the up-down direction, a lateral direction parallel to the left-right direction, and a thickness direction parallel to the front-rear direction. The panel 1 has, for example, a length in the up-down direction of 0.5 to 6.0 m, a length (width) in the left-right direction of 0.2 to 1.5 m, and a length (thickness) in the front-rear direction of 50 to 150 mm.

[0016] The core material 12 includes a main body having thermal insulation properties, and fireproof parts arranged at the left and right ends of the main body and having higher fire resistance than the main body. The main body is, for example, a plurality of blocks of fibrous inorganic material such as rock wool or glass wool bound with a binder or the like arranged in the shape of a single rectangular board. The fireproof parts are, for example, gypsum board or calcium silicate board, and are arranged in recesses provided at the left and right ends of the main body. The main body may be formed of a foam-based organic material such as urethane foam or phenol foam, or may be a styrene board, urethane board, or the like.

[0017] Each of the pair of metal skins 10, 11 is obtained by forming a metal plate into a desired shape by rolling, pressing, etc. The metal plate has a thickness of, for example, 0.25 to 2.0 mm. The metal plate may be, but is not limited to, a painted steel plate, a zinc-plated steel plate, an aluminum-zinc alloy-plated steel plate, a Galvalume steel plate (registered trademark), an SGL (registered trademark) steel plate, etc.

[0018] Of the pair of metal skins 10, 11, the metal skin 10 located at the front side has a rectangular box shape that opens toward the rear side. The metal skin 10 has a rectangular plate-shaped main body 100 that covers the front side of the core material 12, an upper wall portion 101 that covers the front part of the upper surface of the core material 12, a lower wall portion 103 that covers the front part of the lower surface of the core material 12, and left and right side wall portions that cover the front parts of the left and right side surfaces of the core material 12. Of the pair of metal skins 10, 11, the metal skin 11 located at the rear side has a rectangular plate-shaped main body 110 that covers the rear surface of the core material 12, and left and right side wall portions that cover the rear parts of the left and right side surfaces of the core material 12. Note that the metal skin 11 does not have a portion that covers the upper surface or the lower surface of the core material 12. The main body portions 100, 110 of each of the metal skins 10, 11 are bonded to the front and rear surfaces of the core material 12, and are integrated with the core material 12.

[0019] <Beam> As shown in Figs. 1 and 2, the horizontal member (ruler angle (through)) 3 is fixed to a building skeleton 2, and in this embodiment, is an angle member that is L-shaped when viewed from the side. The horizontal member 3 is made of steel. The horizontal member 3 has a base portion 30 and a horizontal plate portion 31 that extends rearward from the lower end portion of the base portion 30. The base portion 30 is formed in a plate shape that protrudes approximately perpendicularly from the horizontal plate portion 31, and its thickness (length in the front-to-rear direction) is, for example, less than 10 mm, and preferably about 6 to 9 mm.

[0020] The building skeleton 2 is a structural member of a building, and examples thereof include columns, beams, foundations, floors, and waist walls. The horizontal board portion 31 of the cross member 3 is fixed to the base metal fittings 21 embedded in the building skeleton 2 by means of bolts, screws, welding, or other means. This results in the base portion 30 protruding from the surface of the building skeleton 2. For example, when the horizontal board portion 31 is fixed to the base metal fittings 21 exposed on the top surface of the building skeleton 2, the base portion 30 protrudes upward from the top surface of the building skeleton 2.

[0021] <Self-weight support device> The weight receiver 4 is a metal fitting for receiving the weight of the panel 1. The panel 1 is attached to the cross member 3 with the weight receiver 4 attached to the rear surface. The weight receiver 4 is provided at approximately the center of the width direction (left-right direction) of the panel 1 after attachment. The weight receiver 4 is further provided at the lower part of the panel 1 after attachment. The weight receiver 4 has a fixing member 41, a supporting member 42, a height adjustment bolt 43, and a nut 44. The fixing member 41 and the supporting member 42 are formed as separate bodies (separate members), and the fixing member 41 and the supporting member 42 are separated before the panel 1 is attached (see FIG. 3B). The height adjustment bolt 43 and the nut 44 are provided on the fixing member 41 before and after the panel 1 is attached.

[0022] 3A and 3B, the fixing member 41 is a metal fitting (made of, for example, steel) that is fixed to the panel 1. The fixing member 41 has a bolt holding portion 411, a fastening portion 412, and a receiving portion 413.

[0023] The bolt holding portion 411 is formed in a plate shape and protrudes toward the rear of the panel 1. The bolt holding portion 411 protrudes approximately perpendicularly to the surface of the main body portion 110 of the metal skin 11 that constitutes the rear surface of the panel 1. The bolt holding portion 411 is provided with a height adjustment bolt 43. The height adjustment bolt 43 is coupled to a female thread portion (tapped portion) 414 that penetrates the bolt holding portion 411 in the thickness direction. The height adjustment bolt 43 is also coupled to a nut 44 provided on the upper surface of the bolt holding portion 411. That is, the height adjustment bolt 43 penetrates the bolt holding portion 411 in the vertical direction, the head of the height adjustment bolt 43 is located above the bolt holding portion 411 and the nut 44, and the tip (lower end) of the height adjustment bolt 43 is located below the bolt holding portion 411. The body of the height adjustment bolt 43 is coupled to the female thread portion 414 and the nut.

[0024] The fixing portion 412 is formed in a plate shape and is disposed along the rear surface of the panel 1. The fixing portion 412 is fixed to the main body portion 110 of the metal skin 11 with fasteners such as screws. The fixing portion 412 is formed so as to protrude substantially vertically downward from the front end portion of the bolt holding portion 411. In other words, the bolt holding portion 411 is formed so as to protrude substantially vertically rearward from the upper end of the fixing portion 412.

[0025] The receiving portion 413 is formed in a plate shape and is disposed along the lower surface of the panel 1. The receiving portion 413 is fixed to the lower wall portion 103 of the metal skin 10 with fasteners such as screws. The receiving portion 413 is formed so as to protrude substantially vertically forward from the lower end portion of the fixing portion 412. In other words, the fixing portion 412 is formed so as to protrude substantially vertically upward from the rear end of the receiving portion 413.

[0026] The support member 42 is an angle bar having an L-shape in a side view. The support member 42 is made of steel, for example. The support member 42 has a bolt support portion 421 and an attachment portion 422 extending downward from the front end portion of the bolt support portion 421. After the panel 1 is attached, the support member 42 is disposed below the receiving portion 413 of the fixing member 41 and behind the fastening portion 412. At this time, the bolt support portion 421 is located below the bolt holding portion 411 and faces the bolt holding portion 411. The attachment portion 422 is disposed along the rear surface of the fastening portion 412. The height adjustment bolt 43 provided on the fixing member 41 has a tip that abuts against the bolt support portion 421. Therefore, the height adjustment bolt 43 is supported from below by the bolt support portion 421. The bolt support portion 421 and the attachment portion 422 are formed in a plate shape, and the thickness thereof is, for example, less than 10 mm, and preferably about 6 to 9 mm.

[0027] <Upper mounting part> The mounting structure for the panel 1 according to this embodiment further includes an upper mounting member 5. As shown in FIG.

[0028] The upper base plate 50 is an L-shaped member in a side view. The upper base plate 50 is formed, for example, by bending a steel plate thicker than the metal skins 10 and 11. The upper base plate 50 has a first piece 501 along the upper end of the rear surface of the panel 1, and a second piece 502 extending forward from the upper end of the first piece 501 and along the upper surface of the panel 1. Each of the first piece 501 and the second piece 502 is a rectangular plate. The first piece 501 is fixed to the upper end of the main body 110 of the metal skin 11 of the panel 1 with a fixing tool such as a screw. The second piece 502 has a front end fixed to the upper wall 101 of the metal skin 10 of the panel 1 with a fixing tool such as a screw. The first piece 501 is provided with a fixing hole to which a bolt 52 is connected.

[0029] The upper plate 51 is rectangular. The upper plate 51 is formed of, for example, a steel plate thicker than the metal skins 10 and 11. The upper plate 51 has an insertion hole in its lower part into which the bolt 52 is inserted. The lower part of the upper plate 51 is fixed to the first piece part 501 of the upper base plate 50 by the bolt 52, and the upper part of the upper plate 51 protrudes upward from the upper surface of the panel 1. The protruding part 510 of the upper plate 51 protruding upward from the upper surface of the panel 1 is a part fixed to the cross member 3. The bolt 52 penetrates the main body part 110 of the metal skin 11 of the panel 1, and its tip part is embedded in the core material 12.

[0030] A plurality of upper mounting members 5 are provided for one panel 1. When two upper mounting members 5 are used, one upper mounting member 5 is provided near one side end face of the panel 1, and the other upper mounting member 5 is provided near the other side end face of the panel 1. In other words, an upper mounting member 5 is disposed on each of both side ends of the panel 1 in the left-right direction.

[0031] <Lower locking member> The mounting structure for the panel 1 according to this embodiment further includes a lower locking member 6. The lower locking member 6 includes a lower base plate 60 and a fastener 61.

[0032] As shown in FIG. 4, the lower base plate 60 is an L-shaped member in a side view. The lower base plate 60 is formed, for example, by bending a steel plate thicker than the metal skins 10 and 11. The lower base plate 60 has a first piece 601 that runs along the lower end of the rear surface of the panel 1, and a second piece 602 that extends forward from the lower end of the first piece 601 and runs along the lower surface of the panel 1. Each of the first piece 601 and the second piece 602 has a rectangular plate shape. The first piece 601 is fixed to the lower end of the main body 110 of the metal skin 11 of the panel 1 with a fastener such as a screw. The second piece 602 has a front end that is fixed to the lower wall 103 of the metal skin 10 of the panel 1 with a fastener such as a screw. The first piece 601 is provided with a fixing hole 64 to which the bolt 63 is coupled. Two fixing holes 64 are provided side by side in the vertical direction. The first piece 601 also has position marks 617. Two position marks 617 are provided on each side end of the first piece 601. The position marks 617 can be formed by cutouts. The upper position mark 617 is formed at a position corresponding to the upper fixing hole 64, and the lower position mark 617 is formed at a position corresponding to the lower fixing hole 64.

[0033] The fastener 61 is a plate-like member having a Z-shape in a side view. The fastener 61 is formed, for example, by bending a steel plate thicker than the metal skins 10 and 11. The fastener 61 has a rectangular plate-like panel fixing portion 611, a rectangular plate-like connecting portion 612 that is continuous with the lower end of the panel fixing portion 611 and inclined with respect to the panel fixing portion 611, and a hook portion 613 that is continuous with the lower end of the connecting portion 612. The panel fixing portion 611 is provided with an insertion hole 631 into which the bolt 63 is inserted. The insertion hole 631 is an elongated hole that extends in the vertical direction. The hook portion 613 is not rectangular plate-like, but is formed in a plate shape with a corner of the tip (the end opposite to the connecting portion 612) removed. That is, the corner of the tip of the hook portion 613 is formed into a chamfered portion 614 that is cut obliquely.

[0034] The panel fixing portion 611 is a portion that is temporarily fixed or fixed to the first piece portion 601 of the lower base plate 60 by the bolt 63. The bolt 63 is connected to one of the two fixing holes 64. This allows the vertical position of the fastener 61 relative to the lower base plate 60 to be adjusted, and the fixing position of the fastener 61 relative to the panel 1 to be changed in multiple stages. The fastener 61 is also provided with an indicator 616. The indicator 616 can be formed by a notch provided in a side end portion of the fastener 61. The indicator 616 serves as a guide to make it easier to determine whether the bolt 63 is connected to the upper fixing hole 64 or the lower fixing hole 64.

[0035] With the panel fixing portion 611 fixed to the first piece 601 of the lower base plate 60, the bolt 63 penetrates the main body 110 of the metal skin 11 of the panel 1 and its tip is embedded in the core material 12. The hook portion 613 is located rearward and away from the first piece 601 of the lower base plate 60. The first piece 601 of the lower base plate 60, the connecting portion 612, and the hook portion 613 form an insertion groove 615 that opens downwardly, surrounding the insertion groove 615.

[0036] A plurality of lower locking members 6 are provided for one panel 1. When two lower locking members 6 are used, one lower locking member 6 is provided near one side end face of the panel 1, and the other lower locking member 6 is provided near the other side end face of the panel 1. In other words, a lower locking member 6 is disposed on each of both left and right end sides of the panel 1.

[0037] An upper mounting member 5 and a lower locking member 6 are disposed on each of the two side edges of the panel 1 so as to be aligned in a straight line in the vertical direction.

[0038] <Joint plate> The joint plate 7 is disposed between the panel 1 and the cross member 3. The joint plate 7 acts as a spacer to keep the distance between the panel 1 and the cross member 3 constant. Therefore, when multiple panels 1 are arranged vertically and horizontally for construction, the joint plate 7 makes it easier to determine the front-to-back positions of the surfaces of the multiple panels 1, improving the workability of the panel 1.

[0039] The joint plate 7 is formed, for example, by bending a steel plate having a thickness approximately equal to that of the metal skins 10, 11. As shown in FIGS.

[0040] The base plate 71 is formed in a rectangular plate shape extending in the up-down direction. The abutment portion 72 is formed in a piece shape protruding rearward from both side ends of the base plate 71. The hook 73 includes a protruding piece 730 protruding rearward from the upper end of the base plate 71, and a locking piece 731 protruding downward from the tip (rear end) of the protruding piece 730. In order to make the hook 73 elastic, the locking piece 731 is inclined forward (in the direction approaching the base plate 71) from the upper end to the lower end.

[0041] Furthermore, the joint plate 7 is provided with a marking 70. The marking 70 serves as a guide for the position where the panel 1 is to be installed. In this embodiment, the marking 70 is formed as a slit. This slit is formed from the upper part of the base plate portion 71 to the front part of the protruding piece 730. The slit is also formed in the approximate center in the width direction (left-right direction) of the base plate portion 71 and the protruding piece 730. The width dimension of the slit is also formed to be approximately the same as the joint width of the panel 1 adjacent in the left-right direction.

[0042] There are two types of joint plates 7: long joint plates 7a (see Figs. 5A-E) and short joint plates 7b (see Figs. 6A-E). The short joint plates 7b have a shorter vertical dimension than the long joint plates 7a. The short joint plates 7b are used when the lower end of the panel 1 fits at the waist wall 2a. The vertical length of the short joint plates 7b is a length that fits within the vertical dimension of the cross member 3 (for example, within the ruler (through) angle L-65×65). On the other hand, when the upper panel 1 overlaps the upper side of the lower panel 1, the cross member 3 (ruler angle (through)) is above the upper end of the lower panel 1, so the long joint plates 7a require the vertical dimension of the cross member 3, the width of the horizontal joint between the upper and lower panels (vertical dimension), and the overlap length of the lower panel 1.

[0043] <Panel installation> The mounting structure of the panel 1 according to this embodiment is formed as follows.

[0044] As shown in FIG. 7, the panel 1 is attached to the cross member 3 by the deadweight receiver 4, the upper mounting member 5, and the lower locking member 6. The fixing member 41 of the deadweight receiver 4 is attached to the lower end of the panel 1 before attachment, approximately in the center of the panel 1 in the left-right direction. The support member 42 of the deadweight receiver 4 is separated from the fixing member 41 before attachment of the panel 1, and is attached to the cross member 3. The lower locking members 6 are attached to the lower end of the panel 1, one each near both left-right ends of the panel 1. Thus, one lower locking member 6 is attached between the deadweight receiver 4 and one side end of the panel 1, and another lower locking member 6 is attached between the deadweight receiver 4 and the other side end of the panel 1. The upper mounting members 5 are attached to the upper end of the panel 1, one each near both left-right ends of the panel 1. At both side ends of the panel 1, the upper mounting members 5 and the lower locking members 6 are attached in a straight line in the vertical direction.

[0045] <<When the building structure is a waist wall>> The case of attaching the panel 1 to a waist wall 2a of a building as the building framework 2 will be described.

[0046] As shown in Fig. 8B and Fig. 9, a joint plate 7 is attached to the cross member 3 fixed to the waist wall 2a. Here, a short joint plate 7b is used for the cross member 3 fixed to the waist wall 2a. The short joint plate 7b is arranged at a position corresponding to the joint formed between adjacent panels 1 in the left-right direction. The short joint plate 7b is attached to the base portion 30 of the cross member 3. That is, as shown in Fig. 9, the short joint plate 7b is attached to the base portion 30 so that the base portion 30 is sandwiched between the abutment portion 72 and the locking piece 731 of the hook 73. In this case, the base portion 71 of the short joint plate 7b is located on the front side of the base portion 30.

[0047] Further, the support member 42 of the weight support device 4 is attached to the cross member 3 fixed to the waist wall 2a. The support member 42 is attached to the base portion 30 of the cross member 3 in a state separated from the fixing member 41. The support member 42 is brought close to the cross member 3 from the front and hooked onto the base portion 30. That is, the bolt support portion 421 of the support member 42 is placed on the upper end portion of the base portion 30 and the mounting portion 422 of the support member 42 is arranged along the front surface of the base portion 30, whereby the support member 42 is hooked onto the base portion 30. The support member 42 is temporarily fixed to the cross member 3 with double-sided tape, adhesive, or the like.

[0048] Thereafter, the panel 1 is brought close to the cross member 3 from the front, and the fixing member 41 arranged on the rear surface of the panel 1 is arranged on the support member 42 attached to the cross member 3, as shown in Fig. 10A and Fig. 10B. That is, the panel 1 provided with the fixing member 41 is arranged so that the support member 42 is located below the receiving portion 413 of the fixing member 41 attached to the panel 1 and behind the fastening portion 412. Also, the mounting portion 422 is sandwiched and fixed between the fastening portion 412 of the fixing member 41 and the base portion 30. In this way, the approximate center in the width direction of the panel 1 is fixed to the base portion 30 of the cross member 3 by the weight receiving device 4.

[0049] 11A and 11B, both ends in the width direction of the panel 1 are fixed to the base portion 30 of the cross member 3 by the lower locking members 6. In this case, the base portion 30 is positioned in the insertion groove 615, and the bolt 63 is tightened so that the base portion 30 is sandwiched between the first piece 601 of the lower base plate 60 and the hook portion 613 of the fastener 61. Since a gap equivalent to the thickness of the mounting portion 422 of the support member 42 is likely to occur between the first piece 601 and the base portion 30, a spacer plate 32 is provided on the front surface of the base portion 30 at a position opposite to the first piece 601. Therefore, by positioning the base portion 30 and the spacer plate 32 in the insertion groove 615 and tightening the bolt 63, the base portion 30 and the spacer plate 32 are sandwiched between the first piece portion 601 and the hook portion 613, and both widthwise ends of the panel 1 are fixed to the base portion 30 of the cross member 3 by the lower retaining member 6.

[0050] The base portion 30 is positioned in the insertion groove 615 as follows. First, as shown in FIG. 12A, the fastener 61 is rotated around the bolt 63 so that the hook portion 613 is positioned above the panel fixing portion 611 and the connecting portion 612. At this time, the bolt 63 is not tightly fastened. After that, the panel 1 is brought closer to the cross member 3 from the front, and the fastener 61 is positioned above the base portion 30. Next, as shown in FIG. 12B and FIG. 12C, the fastener 61 is rotated around the bolt 63 so that the hook portion 613 is gradually positioned below the panel fixing portion 611 and the connecting portion 612. At this time, since the tip of the hook portion 613 is formed as the chamfered portion 614, the tip of the hook portion 613 is less likely to be caught by the horizontal plate portion 31 of the cross member 3, compared to when the tip of the hook portion 613 has a corner, and the fastener 61 can be rotated smoothly. Then, as shown in Fig. 12D, the fastener 61 is rotated until the fastener 61 hangs from the bolt 63 due to its own weight (the hook portion 613 faces the base portion 30), and then, as shown in Fig. 12E, the vertical position of the fastener 61 is finely adjusted, and then the bolt 63 is tightened to prevent the fastener 61 from rotating. In this manner, the base portion 30 and the spacer plate 32 are positioned in the insertion groove 615, and the base portion 30 and the spacer plate 32 are sandwiched between the first piece portion 601 of the lower base plate 60 and the hook portion 613 of the fastener 61. As a result, the fastener 61 is less likely to get in the way when the panel 1 is attached to the cross member 3, improving the workability of the panel 1.

[0051] As shown in FIG. 13, the side end of the panel 1 is disposed in front of the above-mentioned short joint plate 7b attached to the base portion 30. In this case, the side edge portion 112 of the panel 1 is arranged along the marking 70 of the base portion 71 of the short joint plate 7b. When the marking 70 is a slit, the side edge portion 112 of the panel 1 is arranged along the up-down direction on one of the edges arranged in the left-right direction of the slit (the edge portion closer to the panel 1). This makes it easy to position the panel 1 in the left-right direction. In addition, the rear surface of the panel 1 is in contact with the surface of the base portion 71 of the short joint plate 7b. Therefore, the front-rear direction position of the front surface of the panel 1 is determined by the short joint plate 7b.

[0052] Then, in the same manner as above, a plurality of panels 1 are arranged in the left-right direction and attached to the cross members 3 of the waist wall 2a. Here, vertical joints extending in the up-down direction are formed between the panels 1 adjacent in the left-right direction, but in this embodiment, the joint width of all the joints is easily formed to be approximately uniform. That is, the panels 1 adjacent in the left-right direction are arranged along the edge of the slit whose side edge portion 112 is the marking 70. That is, the short joint plate 7b is arranged across the panels 1 adjacent in the left-right direction. Therefore, as shown in FIG. 13, a gap 113 corresponding to the width dimension of the slit is formed between the panels 1 adjacent in the left-right direction, and this gap can be used as a joint. Therefore, by positioning the plurality of panels 1 arranged in the left-right direction using the marking 70 of the short joint plate 7b as a guide, the joint width of all the joints (vertical joints) is easily formed to be approximately uniform, and the workability of the panel 1 is improved. The marking 70 can be formed to have a slit width of 6 mm, for example. This is the same as the joint width on the rear side (inner skin side) of panel 1. Also, before installing panel 1, the center of the panel joint is marked out on the cross member 3 on the building framework 2 side, and by checking this marking through the slit, the installation position of panel 1 will not shift.

[0053] The waist wall 2a has a high surface portion 22 and a low surface portion 23. The low surface portion 23 is located lower than the high surface portion 22. The low surface portion 23 is formed further forward (toward the outdoors) than the high surface portion 22. The base metal fittings 21 are provided on the high surface portion 22. The base metal fittings 21 are fixed to the base metal fittings 21, and the pedestal portions 30 of the cross members 3 are located above the low surface portion 23. The panel 1 attached to the pedestal portions 30 is located above the low surface portion 23.

[0054] In Fig. 10A and Fig. 11A, the lower end surface of the panel 1 is disposed at a position lower than the high surface portion 22. In Fig. 10B and Fig. 11B, the lower end surface of the panel 1 is disposed at approximately the same height as the high surface portion 22. As can be seen from Fig. 10A and Fig. 10B, the height of the center of the lower end surface of the panel 1 is adjusted by the height adjustment bolt 43. That is, as shown in Fig. 10A, when the insertion amount of the height adjustment bolt 43 into the bolt holding portion 411 is small, the interval between the bolt holding portion 411 and the bolt support portion 421 becomes narrow, and the panel 1 is attached at a low position (a position closer to the low surface portion 23). On the other hand, as shown in Fig. 10B, when the insertion amount of the height adjustment bolt 43 into the bolt holding portion 411 is large, the interval between the bolt holding portion 411 and the bolt support portion 421 becomes wide, and the panel 1 is attached at a high position (a position farther from the low surface portion 23).

[0055] When adjusting the height of the height adjustment bolt 43, first, the nut 44 is loosened from the height adjustment bolt 43 (the nut 44 is separated upward from the bolt holding portion 411). Next, the position (height) of the height adjustment bolt 43 relative to the bolt holding portion 411 is adjusted by rotating the height adjustment bolt 43 relative to the female thread portion 414. After this, the nut 44 is tightened from the height adjustment bolt 43 (the nut 44 is in contact with the upper surface of the bolt holding portion 411). The height adjustment bolt 43 adjusted in this way is unlikely to loosen due to vibration or the like. That is, the height adjustment bolt 43 is unlikely to loosen (to rotate) from the female thread portion 414 due to the anti-loosening effect of the nut 44, and the height of the height adjustment bolt 43 is unlikely to fluctuate due to vibration or the like.

[0056] 11A and 11B, the height of both sides of the lower end surface of panel 1 is adjusted by the attachment position of lower engaging member 6 with respect to panel 1. That is, as shown in Fig. 11A, when fastener 61 is fixed to upper fixing hole 64 provided in lower base plate 60, panel 1 is attached at a low position (a position closer to bottom surface portion 23). On the other hand, as shown in Fig. 11B, when fastener 61 is fixed to lower fixing hole 64 provided in lower base plate 60, panel 1 is attached at a high position (a position farther from bottom surface portion 23).

[0057] Furthermore, a fire-resistant material 24 is filled between the bottom surface 23 and the lower end surface of the panel 1. The fire-resistant material 24 is formed of, for example, rock wool. Furthermore, a backup material 150 is provided between the bottom surface 23 and the lower end surface of the panel 1, and a sealing material 151 is provided in front of the backup material 150 (on the outdoor side). The backup material 150 and the sealing material 151 are provided in front of the fire-resistant material 24 (on the outdoor side).

[0058] In the above, the case where the building structure 2 is a waist wall 2a has been described, but the panel 1 can be attached in the same manner when the building structure 2 is a foundation.

[0059] <<When the building structure is other than a waist wall>> Next, a case where the panel 1 is attached to a building skeleton 2 other than the waist wall 2a will be described. Examples of the building skeleton 2 other than the waist wall 2a include beams, columns, and floors. In this embodiment, the building skeleton 2 is a floor 2b, but is not limited to this.

[0060] As described above, the lower end of the lowest panel 1 among the multiple panels 1 lined up in the vertical direction is attached to the waist wall 2a. On the other hand, as shown in Figures 1A, 1B, 2A and 2B, since the floor 2b is located above the waist wall 2a, the upper end of the lowest panel 1, or the upper and lower ends of the panels 1 adjacent in the vertical direction, are attached to the floor 2b.

[0061] The panel 1 is attached to the cross member 3 fixed to the floor 2b by the weight receiving device 4, the upper mounting member 5, and the lower locking member 6 in the same manner as described above. As described above, the fixing member 41 of the weight receiving device 4 is attached to the lower end of the panel 1 before installation, approximately in the center of the panel 1 in the left-right direction. The support member 42 of the weight receiving device 4 is separated from the fixing member 41 before the panel 1 is installed, and is attached to the cross member 3. In addition, a joint plate 7 is attached to the cross member 3 fixed to the floor 2b. Here, a long joint plate 7a is used for the cross member 3 fixed to the floor 2b. The long joint plate 7a is arranged at a position corresponding to the joint formed between the panels 1 adjacent in the left-right direction. As shown in Figures 14 and 15, the long joint plate 7a is attached to the base portion 30 of the cross member 3 in the same manner as described above. That is, the long joint plate 7a is attached to the base portion 30 so that the base portion 30 is sandwiched between the abutment portion 72 and the locking piece 731 of the hook 73. In this case, the base portion 71 of the long joint plate 7a is located in front of the base portion 30. In addition, the lower part of the long joint plate 7a is located below the base portion 30.

[0062] Next, of the panels 1 adjacent in the vertical direction, the lower panel 1 is constructed. The lower end of the lower panel 1 is attached to the cross member 3 fixed to the waist wall 2a or the floor 2b by the weight receiving device 4 and the lower locking member 6 in the same manner as above. The upper end of the lower panel 1 is positioned by the lower part of the long joint plate 7a provided on the cross member 3 fixed to the floor 2b (another cross member 3 above the cross member 3 to which the lower end of the lower panel 1 is attached). That is, the rear surface of the upper end of the lower panel 1 contacts the surface of the base plate part 71 at the lower part of the long joint plate 7a, so that the surface of the upper end of the lower panel 1 is positioned in the front-rear direction. In addition, the side edge part 112 of the lower panel 1 is aligned with the marking 70 of the long joint plate 7a. As a result, the upper end of the lower panel 1 is positioned in the left-right direction. Furthermore, the upper part of the upper plate 51 provided on the lower panel 1 is positioned in front of the base part 30 of the cross member 3.

[0063] Next, of the panels 1 adjacent in the vertical direction, the upper panel 1 is constructed. The lower end of the upper panel 1 is attached to the cross member 3 fixed to the floor 2b by the weight receiving device 4 and the lower locking member 6 in the same manner as described above. Here, the upper part of the upper plate 51 provided at the upper end of the lower panel 1 is located in front of the base part 30 of the cross member 3. Therefore, as shown in Figures 1A, 1B, 2A and 2B, the upper parts of the base part 30 and the upper plate 51 are positioned in the insertion groove 615, and the bolt 63 is tightened to sandwich the upper parts of the base part 30 and the upper plate 51 between the first piece part 601 of the lower base plate 60 of the upper panel 1 and the hook part 613 of the fastener 61. As a result, the upper end of the lower panel 1 is attached to the cross member 3 via the upper mounting member 5.

[0064] The side end of the upper panel 1 is disposed in front of the long joint plate 7a attached to the base 30. In this case, the side edge 112 of the upper panel 1 is aligned with the marking 70 of the base 71 of the long joint plate 7a. When the marking 70 is a slit, the side edge 112 of the panel 1 is disposed in the up-down direction on one of the edges (the edge closer to the panel 1) arranged in the left-right direction of the slit. This makes it easy to position the upper panel 1 in the left-right direction. Also, the rear surface of the upper panel 1 is in contact with the surface of the base 71 of the long joint plate 7a. Therefore, the front-rear position of the front surface of the upper panel 1 is determined by the long joint plate 7a.

[0065] In this way, a plurality of panels 1 are arranged in the left-right direction and attached to the cross member 3 of the floor 2b. A plurality of panels 1 are also arranged in the up-down direction and installed. After this, the exterior wall of the building is formed by providing a backup material 150 and a sealant 151 in the joints between adjacent panels 1 in the up-down and left-right directions. The backup material 150 and the sealant 151 are provided in front (on the outside side) of the packing 152 provided on the upper end surface and the lower end surface of the panel 1. The vertical position (height position) of the panel 1 can be adjusted by the height adjustment bolt 43. That is, by adjusting the length of the part of the height adjustment bolt 43 that protrudes downward from the bolt holding part 411 while the tip of the height adjustment bolt 43 is in contact with the bolt support part 421, the panel 1 can be moved up and down relative to the support member 42 fixed to the cross member 3 to adjust the height. The adjustment range of the height of the panel 1 is not particularly limited, but is preferably about 3 cm, and the adjustment range of the height of the panel 1 can be increased by making the height adjustment bolt 43 longer.

[0066] In Fig. 1A and Fig. 2A, the lower end surface of the panel 1 is disposed at a position lower than the upper surface of the floor 2b. In Fig. 1B and Fig. 2B, the lower end surface of the panel 1 is disposed at approximately the same height as the upper surface of the floor 2b. As can be seen from Fig. 1A and Fig. 1B, the height of the center of the lower end surface of the panel 1 is adjusted by the height adjustment bolt 43. That is, as shown in Fig. 1A, when the insertion amount of the height adjustment bolt 43 into the bolt holding portion 411 is small, the interval between the bolt holding portion 411 and the bolt support portion 421 becomes narrow, and the panel 1 is attached at a low position (a position lower than the upper surface of the floor 2b). On the other hand, as shown in Fig. 1B, when the insertion amount of the height adjustment bolt 43 into the bolt holding portion 411 is large, the interval between the bolt holding portion 411 and the bolt support portion 421 becomes wide, and the panel 1 is attached at a high position (approximately the same height position as the upper surface of the floor 2b).

[0067] 2A and 2B, the height of both sides of the lower end surface of the panel 1 is adjusted by the attachment position of the lower engaging member 6 with respect to the panel 1. That is, as shown in Fig. 2A, when the fastener 61 is fixed to the upper fixing hole 64 provided in the lower base plate 60, the panel 1 is attached at a low position (a position lower than the upper surface of the floor 2b). On the other hand, as shown in Fig. 2B, when the fastener 61 is fixed to the lower fixing hole 64 provided in the lower base plate 60, the panel 1 is attached at a high position (a position approximately the same height as the upper surface of the floor 2b).

[0068] In this embodiment, when constructing the panel 1, the support members 42 for supporting the height adjustment bolts 43 are not welded, bolted, or screwed to the cross members 3. Therefore, for example, sparks generated during construction of the panel 1 can be prevented from scattering to surrounding combustible materials, and the risk of fire and accidents such as scorching of the panel and tripping over the cord of the welding machine can be suppressed. Post-process work such as preparation for welding, welding work, touch-up (repair) of the welded parts, and checking the length of the welded parts can be omitted, and the installation work of the panel 1 can be shortened.

[0069] (3) Variations The first embodiment is merely one of various embodiments of the present disclosure. The first embodiment can be modified in various ways depending on the design and the like as long as the object of the present disclosure can be achieved.

[0070] The mounting structure of the panel 1 according to this embodiment can be applied not only to an exterior wall but also to an interior wall.

[0071] The panel 1 is not limited to a sandwich panel, and plywood, ALC panel, metal plate, gypsum board, etc. can be used.

[0072] (summary) As described above, the panel mounting structure according to the first embodiment includes a panel (1), a cross member (3) fixed to a building structure (2), and a weight support (4) for mounting the panel (1) to the cross member (3). The cross member (3) has a base portion (30) protruding from the building structure (2).

The support member (42) further has a mounting portion (422) that is sandwiched between the fastening portion (412) and the base portion (30), and is not welded or screwed to the cross member (3).

[0075] According to the second aspect, with the mounting portion (422) sandwiched between the fixing portion (412) and the base portion (30), the support member (42) is fixed to the base portion (30) and is not welded or screwed to the cross member (3). Therefore, there is no need to perform fixing work such as welding and screwing on the support member (42), which tends to improve the workability of the panel (1).

[0076] A third aspect is a mounting structure for a panel (1) according to the first or second aspect, further comprising a fastener (61) disposed behind the panel (1). The fastener (61) has a chamfered portion (614), is attached rotatably with respect to the panel (1), and is hooked onto the base portion (30).

[0077] According to the third aspect, the panel (1) can be attached to the cross member (3) by means of the fastener (61) hooked onto the base portion (30), which tends to improve the workability of the panel (1).

[0079] According to the fourth aspect, the fixing position of the fastener (61) relative to the panel (1) can be changed in a plurality of stages, which tends to improve the workability of the panel (1).

[0080] The fifth aspect is a mounting structure for a panel (1) according to the third or fourth aspect, in which the fastener (61) has an indicator (616) that indicates the position at which the fastener is fixed to the panel (1) by the bolt (63).

[0081] According to the fifth aspect, the indication portion (616) makes it easier to determine the fixing position of the fastener (61), which tends to improve the ease of installation of the panel (1).

[0082] A sixth aspect is a mounting structure for a panel (1) according to any one of the first to fifth aspects, further comprising a joint plate (7) disposed between the panel (1) and the cross member (3). The joint plate (7) is in contact with the rear surface of the panel (1) at a side end of the panel (1).

[0083] According to the sixth aspect, the joint plate (7) allows the panel (1) to be aligned in the front-rear direction, which tends to improve the workability of the panel (1).
