[0009] The present invention will be described below with reference to the drawings, based on preferred embodiments. The following configurations are illustrative for the purpose of understanding the present disclosure, and the scope of the present disclosure is defined solely by the appended claims. Identical or equivalent components and members shown in each drawing are denoted by the same reference numerals, and redundant descriptions are omitted where appropriate. In addition, the dimensions of members in each drawing are shown enlarged or reduced as appropriate for ease of understanding. Furthermore, some members that are not important for explaining the embodiments are omitted in each drawing.

[0010] Figure 1 shows an example of a building to which the wall panel mounting structure according to the embodiment can be applied. The building 100 shown in Figure 1 comprises a frame 110, wall panels 10 attached to the side of the frame 110, interior panels 103 attached to the inside of the wall panels 10, windows 114 attached to part of the side, ceiling panels 105, and floor panels 116 attached to the bottom surface of the frame 110.

[0011] The structural frame 110 is formed by the connection of multiple foundations 101, multiple columns 102, and multiple beams 104, 106 to constitute a rigid frame structure. In Figure 1, a cubic structural frame 110 is shown as an example, but the shape of the structural frame 110 is not particularly limited, and it may be, for example, a rectangular parallelepiped.

[0012] Figure 2 is a schematic vertical cross-sectional view illustrating the mounting structure of a wall panel according to an embodiment. Figure 2 shows a state in which a wall panel 10A is attached to a base 101 provided on the foundation 120 of a building and a beam 104 located above the base 101. Another wall panel 10B is attached above wall panel 10A. Figure 3 is a schematic vertical cross-sectional view of the joint between wall panel 10A and wall panel 10B.

[0013] The wall panel 10A comprises an insulating material 11 and surface materials 12 and 13 that cover the insulating material 11. A recess 11a is formed at the lower end of the wall panel 10A. Siding 15 is arranged on the outside of the exterior surface material 12 via a ventilation layer 14.

[0014] A metal frame material 16 extending vertically is attached to the interior surface material 13 by bolts 25. The upper part of the frame material 16 is an upper bracket 17 having an upward-facing locking groove 17a that opens upward. The lower part of the frame material 16 is a lower bracket 18 having a downward-facing locking groove 18a that opens downward. In this embodiment, the upper bracket 17 and the lower bracket 18 are configured as a single unit, but they may be configured as separate parts.

[0015] A metal first fastener 20 is fixed to the base 101. The first fastener 20 has a load-supporting piece 20a fixed to the base 101 and an upward-facing locking piece 20b extending upward from the load-supporting piece 20a. The load-supporting piece 20a is fixed to the base 101 by fastening members such as bolts. A drain 122 equipped with a starter 121 is also fixed to the base 101.

[0016] A second metal fastener 21 is fixed to the beam 104, which is located above the base 101. The second fastener 21 has a load-supporting piece 21a fixed to the beam 104, a downward-facing locking piece 21b extending downward from the load-supporting piece 21a, and an upward-facing locking piece 21c extending upward from the load-supporting piece 21a. As shown in Figure 3, the load-supporting piece 21a is fixed to the beam 104 by fastening members 26 such as bolts.

[0017] The wall panel 10A is attached to the housing 110 by inserting the downward locking piece 21b of the second fastener 21 into the upward locking groove 17a of the upper bracket 17 for locking, and inserting the upward locking piece 20b of the first fastener 20 into the downward locking groove 18a of the lower bracket 18 for locking. Further, a starter 121 protruding upward from the drain 121 is inserted into the recess 11a provided at the lower end of the wall panel 10A.

[0018] In the mounting structure of the wall panel 10A shown in FIG. 2, the first fastener 20 functions as a "lower fastener" located below, and the second fastener 21 functions as an "upper fastener" located above.

[0019] The upward locking piece 21c of the second fastener 21 is inserted into the downward locking groove 18a of the lower bracket 18 provided in the wall panel 10B. When viewed from this other wall panel 10B, the second fastener 21 functions as a "lower fastener". That is, in the present embodiment, one second fastener 21 is shared in the mounting structures of the upper and lower wall panels 10A and 10B. Thereby, the number of parts can be reduced, and cost reduction can be achieved.

[0020] As shown in FIG. 3, a joint heat insulating material 22 is disposed between the wall panel 10A and another wall panel 10B. Thus, by disposing the joint heat insulating material 22 between two juxtaposed wall panels, the heat insulating performance can be improved.

[0021] As shown in FIG. 3, the upward locking piece 21c of the second fastener 21 functioning as a lower fastener and the lower bracket 18 may be fixed with a fastening member such as a bolt 27. In this case, the seismic resistance can be improved.

[0022] Another wall panel 10C is attached to the side of wall panel 10A. Figure 4 is a schematic horizontal cross-sectional view of the joint between wall panel 10A and wall panel 10C. Joint insulation material 22 is placed between wall panel 10A and wall panel 10C.

[0023] An earthquake force receiving member 28 is positioned between the lower bracket 18 of wall panel 10A and the lower bracket 18 of wall panel 10C. As shown in Figure 4, a nut receiving portion 18b is formed on the lower bracket 18. In Figure 4, on the lower bracket 18 of the left wall panel 10A, a nut 30 is placed in the nut receiving portion 18b, and this nut 30 is fastened to the second fastener 21 by fastening with a bolt 27. To improve earthquake resistance, it is preferable to fasten the fastener and bracket with fastening members such as bolts in this manner. On the other hand, the lower bracket 18 of the right wall panel 10C is not fastened with bolts or the like. When earthquake resistance is borne by columns and beams, fastening with bolts or the like is unnecessary.

[0024] Figure 5 shows how the wall panel 10A is attached to the structural frame 110. When attaching the wall panel 10A to the structural frame 110, first, the first fastener 20 having an upward locking piece 20b is fixed to the base 101 using fastening members such as bolts.

[0025] Then, the upward locking piece 20b of the first fastener 20 is inserted into the downward locking groove 18a of the lower bracket 18 in the wall panel 10A. At this time, the starter 121 is also inserted into the recess 11a of the wall panel 10A.

[0026] Furthermore, as shown in Figure 5, the downward locking piece 21b of the second fastener 21 is inserted into the upward locking groove 17a of the upper bracket 17 on the wall panel 10A. Then, the load-supporting piece 21a of the second fastener 21 is fixed to the beam 104 using fastening members 26 such as bolts.

[0027] In this way, the wall panel 10A can be attached to the building structure 110 by inserting and locking the downward locking piece 21b of the second fastener 21 into the upward locking groove 17a of the upper bracket 17, and by inserting and locking the upward locking piece 20b of the first fastener 20 into the downward locking groove 18a of the lower bracket 18.

[0028] Figure 6 shows how another wall panel 10B is attached above wall panel 10A. When attaching wall panel 10B to the frame 110, first, the upward locking piece 21c of the second fastener 21, which is already fixed to the beam 104, is inserted into the downward locking groove 18a of the lower bracket 18 on wall panel 10B. At this time, the joint insulation material 22 is placed between wall panel 10A and wall panel 10B.

[0029] Furthermore, the downward locking piece 23b of the third fastener 23 is inserted into the upward locking groove 17a of the upper bracket 17 on the wall panel 10B. Then, the load-supporting piece 23a of the third fastener 23 is fixed to the beam 106 located above the beam 104. The third fastener 23 may be fixed to the beam 106 using fastening members such as bolts.

[0030] In this way, the wall panel 10B can be attached to the building structure 110 by inserting and locking the downward locking piece 23b of the third fastener 23 into the upward locking groove 17a of the upper bracket 17, and by inserting and locking the upward locking piece 21c of the second fastener 21 into the downward locking groove 18a of the lower bracket 18.

[0031] Subsequently, the coping 24 is attached so as to cover the upper end of the wall panel 10B. The coping 24 has a downward locking groove 24a formed therein. The coping 24 is attached to the building structure 110 by inserting the upward locking piece 23c of the third fastener 23 into the downward locking groove 24a of the coping 24 and fixing it with fastening members such as bolts. Joint insulation material 22 may be placed between the coping 24 and the wall panel 10B.

[0032] In the mounting structure of the wall panel 10B shown in Figure 6, the second fastener 21 functions as a "lower fastener" located below, and the third fastener 23 functions as an "upper fastener" located above.

[0033] Figure 7 shows the mounting structure of a wall panel at a building corner. Figure 8 shows how the wall panel is attached to the building structure at a building corner. As shown in Figures 7 and 8, an L-shaped wall panel 10D is attached to the building corner. This L-shaped wall panel 10D is also equipped with brackets 18 at both ends of the L-shape and is attached to the building structure 110 by being fastened with fasteners 21. A nut receiving portion 18b is formed in the lower bracket 18. A nut 30 is placed in the nut receiving portion 18b, and the fastener 21 and the bracket are fastened and secured by fastening the nut 30 with a bolt 27. In this way, by fixing the wall panel at the building corner with fastening members, the entire wall panel, including other wall panels, can be securely attached.

[0034] As shown in Figures 7 and 8, joint insulation material 22 is also placed between the L-shaped wall panel 10D and the other wall panels. In addition, a water stop plate holder 32 is provided at the end of the L-shaped wall panel 10D. After attaching the wall panel 10D to the structure 110, the water stop plate 34 is inserted between the wall panels as shown in Figure 7 and supported by the water stop plate holder 32, thereby improving the waterproofing function of the exterior wall.

[0035] As described above, in the wall panel mounting structure according to this embodiment, the wall panel is basically attached to the building structure by fastening brackets provided on the wall panel to the building structure with fasteners fixed to the building structure. Since it is only necessary to fix the fasteners to the building structure using fastening members such as bolts, the wall panel can be attached to the building structure more easily compared to conventional construction methods in which wall panels were fixed by driving nails. Furthermore, in the mounting structure according to this embodiment, the wall panel can be easily removed by detaching the fasteners from the building structure. Since there is no need to destroy the wall panel, it can be reused, making it economical.

[0036] The present invention has been described above based on embodiments. These embodiments are illustrative, and it will be understood by those skilled in the art that various modifications and changes are possible within the scope of the claims of the present invention, and that such modifications and changes are also within the scope of the claims of the present invention. Accordingly, the descriptions and drawings herein should be treated as illustrative rather than limiting. [Explanation of symbols]
