Specifically, first, an ALC panel having a predetermined size is manufactured, and a mounting hardware for mounting an exterior material is fixed to the ALC panel. On the other hand, for example, a metal plate is cut out and bent to manufacture an exterior material, and this exterior material is manufactured in a factory.
Attached to the ALC panel to complete the exterior material integrated ALC panel. Then, the panel is transported to the construction site, where it is sequentially fixed to the structural frame of the building.

(Problems to be Solved by the Invention) However, if the above construction method is adopted, the exterior material integrated type ALC panel shipped from the factory has the exterior material integrated in advance, so the thickness of the panel increases, And the weight becomes considerably heavy. For this reason, the transportation efficiency is poor, and the transportation operation becomes large. In addition, there is a problem that the exterior material must be carefully considered so as not to damage the exterior material during transportation or storage of the panel, and there is a problem that the cost required for transportation and storage generally increases. Furthermore, the fact that the panel is heavy and requires careful handling means that the work of lifting it and fixing it to the structural frame of the building will cause difficulties, and the construction efficiency will be poor. Met.

Accordingly, an object of the present invention is to provide a method of constructing a lightweight, aerated concrete panel with an exterior material integrated into a structural body, which can improve work efficiency in transporting panels and the like, and improve construction efficiency.
