。[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a mounting structure for lightweight concrete wall panels constituting the curtain wall of a building, and in particular, an on-site construction method using mounting brackets is important. It is suitable for high-temperature, high-pressure steam-cured lightweight cellular concrete (ALC) wall panels.

４を介して取付ける。<Prior Art> Conventionally, when attaching an ALC wall panel to a steel frame of a building using attachment fittings such as bolts, a structure as shown in FIG. 9 has been used. That is, the chevrons 5i are formed on the upper flange 10a and the lower flange 10b of the steel beam 10, respectively.
I9 is fixed, and mounting bolts that respectively support the lower part 1a and the upper part 1b of the wall panel 1 are attached to the angle iron 9 via the lightning metal fittings 4.

のため第８図に示すように地震時に鉄骨躯体が層間変形
を起こしてもパネルが水平方向にスライスすることによ
り躯体の変形に追従できるというものである。The lightning hardware 4 of the panel lower part 1b is hooked and engaged with the angle iron 9. Moreover, since the lightning hardware 4 on the panel upper part 1a is only hooked and engaged with the angle iron 9, the lightning hardware 4 can move the vertical flange of the angle iron 9 in the in-plane direction. Therefore, as shown in Fig. 8, even if the steel frame structure undergoes interstory deformation during an earthquake, the panels can follow the deformation of the frame by slicing them in the horizontal direction.

という問題がある。Problems to be Solved by the Present Invention> However, in a case where sliding is expected as in this structure, firstly, when panel I slides and deforms as shown in Fig. 8 during an earthquake, the cross-grain between the panels of each layer will occur. A large shearing deformation 11 occurs in the ground sealing material, and a large tensile deformation 12 occurs in the sealing material above the vertical joints around the columns, making it easy to cut these sealing materials and making it difficult to maintain waterproof performance. , the lower flange 1 of the steel beam lO
The angle iron 9 that is fixed to the steel beam 0b is long and quite heavy, so it is difficult to install it from below the steel beam 10.
Moreover, there is a problem in that a large number of metal fittings are used as a whole, resulting in high cost.
