Description

Description: TECHNICAL FIELD The present invention relates to a sandwich panel useful for constructing an outer wall of a building or a building with a dry panel.

(Prior art) This kind of building, for example, as a panel for forming the outer wall of a warehouse with a sandwich panel or the like, a siding material in which a plastic foam is integrally interposed between a metal thin plate having male and female connecting portions and kraft paper, A plastic foam is interposed between metal plates, and a concave / convex portion is formed on a side wall in the longitudinal direction, and a sandwich panel in which the concave / convex portion is inserted is disclosed, or Japanese Utility Model Publication No. Sho 63-20761, Japanese Unexamined Patent Application Publication No. JP-B-57-20741, and the like.

[Problems to be solved by the invention]

However, the conventional metal siding material has a synthetic resin foam integrally interposed between a surface material and a sheet-like material such as kraft paper, and has a male-female connection structure and a structure in which only one end is fixed. When the decorative width is set to about 400 mm and the thickness is set to about 25 mm or more, there are drawbacks that the siding material is easily detached, the decorative surface becomes mountain-shaped, and it is difficult to insert the male and female connecting portions. Also, the sandwich panel has a disadvantage that it has to be constructed with a crane or the like because it lacks aesthetics due to its structure that is beaten in the brain via bolts. Of course, ALC siding and ceramic siding materials were heavy, had limited decorative surface and thickness, were difficult to construct, and had weaknesses in freeze-thaw. Furthermore, although the above described, the cap is attached by the mounting bracket to cover the joint portion and the exposure of the fixture to the external appearance is prevented, the mounting of the cap requires the mounting bracket, and the workability is poor, Moreover, it was inferior in heat insulation and waterproofness. Otherwise, if the installation of the joint cover is not performed properly, the panel may be detached, which also has a disadvantage of poor heat insulation and waterproofness.

[Means for solving the problem]

In order to eliminate such disadvantages, the present invention comprises a metal plate for the front and back surfaces, and a heat insulating material made of a lightweight plastic foam interposed between both surfaces, and on both sides of the decorative surface. An object of the present invention is to provide a sandwich panel on which a joint cover can be mounted without using a mounting bracket by forming an engagement portion which is recessed in a wedge shape for mounting and engaging the joint cover at the time of construction.
