Description

TECHNICAL FIELD The present invention relates to an outer wall material of a building in which a decorative plate is attached to an ALC panel, and more specifically, a holding metal fitting is fixed to the ALC panel, and the makeup is attached via the holding metal fitting. The present invention relates to an outer wall material having a plate attached.

(Prior Art and Problems) ALC panels are used to form the outer wall surface of a building. The ALC panel is porous because it is a lightweight concrete plate that has been aged at high temperature in an autoclave, so it has a great advantage due to the weight reduction. On the other hand, if it is left as it is, it may have high water permeability and lack rigidity.

Therefore, when forming the outer wall surface of the building, it is necessary to spray an organic paint or the like on the surface of the panel to form a waterproof coating film. However, this waterproof coating has a problem that it is poor in durability and does not show a sufficient aesthetic appearance, and therefore, a decorative plate such as a ceramic tile is attached.

In order to attach this type of decorative plate to the ALC panel, it is not possible to obtain sufficient attachment strength in order to fix the anchor bolts and the mounting bracket directly to the ALC panel. Therefore, stick with a special binder, mortar, or adhesive. However, since this sticking means has a so-called wet-type sticking structure, there are variations in durability and coating strength over time.

On the other hand, since the ALC panel has a lower tensile strength than a decorative plate made of a ceramic tile or the like, when a displacement difference due to thermal expansion occurs between the both, the ALC panel itself is cracked, which causes various problems such as peeling.

(Means for Solving Problems) In order to solve the above problems, the present invention relates to an outer wall material in which two or more decorative plates are attached to the surface of an ALC panel at least vertically through a holding metal fitting. Among the decorative plates, the upper end of the uppermost decorative plate and the lower end of the lowermost decorative plate are held by holding fittings having a mounting portion and a claw piece formed in a substantially hook shape, and the decorative plate extending up and down. Holding metal fittings having a pair of mounting portions, each of which is formed in a cantilever shape, with upper and lower ends adjacent to each other having a predetermined gap, and a claw piece formed by bending the tip of each mounting portion in the vertical direction. And an elastic adhesive material is interposed between the rear surface of each of the decorative plates and the ALC panel.
