Further, since it is not necessary to perforate window holes in the lower and side portions of the gypsum board 23 or to close each opened window hole with plaster or the like, it is possible to prevent the mechanical strength of the wall panel 10 itself from being lowered. It becomes possible to prevent. In addition, since a plurality of horizontal crosspieces 15 and crosspieces 16 are arranged and combined in the wall frame 11 to prevent the wall panel 10 from being bent, even if an attempt is made to raise the ceiling by setting the wall panel 10 to a total height of 2.34 m or more. It is possible to effectively ensure excellent strength and rigidity.

  In addition, since the wiring cord 19 of the wiring part 17 is drawn out from the through hole 20 of the upper horizontal rail 13, an excellent airtight structure of the moisture-proof layer 34 can be obtained. In addition, instead of simply filling the wall frame 11 with the filler 22, the plurality of partitioned spaces 21 are filled with the filler 22, respectively, so that displacement of the filler 22 is suppressed and workability is improved. I can expect. Further, since the plurality of fillers 22 are not simply covered with the moisture-proof layer 34, the moisture-proof layer 34 is laminated on the entire inner surface of the wall frame 11, and the periphery of the moisture-proof layer 34 protrudes from the periphery of the wall frame 11. By improving the insulation, it is possible to improve heat insulation, increase the efficiency of energy used, prevent condensation and mold, and prevent corrosion of buildings.

  Moreover, since the lowermost part 32 which the structural plywood 30 extended is piled up and fixed to the outer surface of the floor joist 4, the structural plywood 30 can be temporarily fixed easily. Further, since the moisture-proof layer 34 is sandwiched between the flooring 7 and the lower horizontal rail 14 of the wall panel 10 or between the wall panels 10, a significant improvement in dehumidification, waterproofing and airtightness can be expected. Further, the sealing material 26 is filled in the filling gap 25 between the flooring 7 and the lower lower surface of the gypsum board 23 instead of simply contacting the lower surface of the flooring 7 and the gypsum board 23, so that the moisture-proof layer 34 and the sealing material 26 are filled. Ensuring sufficient airtightness can be expected through the multilayer structure.

  In addition, the wall frame 11 of the wall panel 10 of the said embodiment can be formed in a rectangle or a square, and you may increase / decrease the number of the crosspieces 15 and the crosspieces 16 suitably. In addition, instead of installing a single horizontal beam 15 between a pair of vertical beams 12, a necessary number of horizontal beams 15 are directly installed, or a necessary number of horizontal beams 15 are indirectly connected via a bridge 16 or the like. You may attach it. Further, another layer may be appropriately interposed between the wall frame 11 and the gypsum board 23 and / or between the wall frame 11 and the structural plywood 30.

  In the above embodiment, the wiring cord 19 is used. Instead of the wiring cord 19, at least one or more cables, tubes, outlets, wiring switches, connectors, relay boxes, clamps, wiring hardware, A component fixture, an optical fiber, or the like may be used. In the above embodiment, glass wool is filled, but instead of this glass wool, at least one or more of rock wool, cellulose fiber, insulation board, polyethylene foam, rigid urethane foam, etc. can be filled as the filler 22. .

  In the above embodiment, the liquid sealing material 26 is filled in the filling gap 25 between the flooring 7 and the lower lower surface of the gypsum board 23. However, the present invention is not limited to this. For example, a fixed sealing material 26 can be used. Furthermore, it is also possible to use the wall panel 10 not only for each part of the first floor but also for construction of each part of the second floor.

  The wall panel joining structure and the wall panel joining method according to the present invention are used in fields such as architecture and civil engineering.
