Description

This invention relates to mounting members for attaching wall panels to base metal fittings fixed to the building frame of a structure, a mounting structure for wall panels, a building, and a method for attaching wall panels. As an ALC panel mounting structure, the mounting structure shown in Figure 19 (lightweight aerated concrete panel mounting structure (conventional structure) 50) is widely used. In this mounting structure, the embedded anchor 52 embedded inside the ALC panel 51 and the panel joint surface of the zigzag plate 53 used as a mounting bracket are joined by anchor bolts 54. On the other hand, a base metal fitting 56 with an L-shaped cross-section, which is joined to the building frame 55, is fixed in a manner in which it is sandwiched between the above-mentioned panel joint surface of the zigzag plate 53 and another surface formed to create a step difference by two-stage bending, and the back surface of the ALC panel (Patent Document 1). Regarding the embedding of anchors into ALC panels, while it's possible to pre-embed them during the panel manufacturing process, it's also common practice to drill holes and embed the anchors at the construction site using a standard electric drill. When installation is done manually on-site, errors in the placement of embedded anchors for ALC panels can make installation difficult. If such errors can be compensated for by the mounting brackets, construction defects in wall structures using ALC panels can be reduced, and construction speed can be improved. Therefore, there is a need for mounting brackets that can compensate for errors in the placement of embedded anchors. To meet such requirements, a mounting bracket has been proposed consisting of two brackets: a main plate and an auxiliary plate, each with a specific shape. The auxiliary plate has a structure comprising a protruding flat plate portion and ridge portions extending from both side edges of the protruding flat plate portion in the same direction and at the same height relative to the surface of the protruding flat plate portion (see Patent Document 2). According to the mounting hardware disclosed in Patent Document 2, errors in the embedded anchor placement can be absorbed by the mounting hardware without changing the positional relationship between the ALC panel and the building structure, thereby eliminating the aforementioned errors during the panel installation process.
