Description

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

[Conventional technology]

This type of building, for example, the outer wall of a warehouse as a panel that forms a joint structure of the wall with a sandwich panel or the like, a siding material in which a plastic foam is integrally interposed between a metal sheet having male and female connectors 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, or Japanese Utility Model Publication No. Sho 63-20761, Japanese Patent Application Laid-Open No. Sho 62-7
No. 2858, and Japanese Utility Model Publication No. 57-20741.

[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. The width of the decorative surface is about 400mm,
When the thickness is about 25 mm or more, there are disadvantages 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. Further, the sandwich panel has a disadvantage in that it lacks aesthetics due to its structure being beaten in the brain via bolts, and must be constructed with a crane or the like. 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. Further,
Covers the joint by attaching the cap with the mounting bracket,
Although the fixture was prevented from being exposed to the exterior, the mounting of the cap required a mounting bracket, which was poor in workability and poor in heat insulation and waterproofness. In addition, there is a risk that the joint cover may be detached if the panel is not properly installed, 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. At the time of construction, a sandwich panel formed with a wedge-shaped recessed engagement portion to which a joint cover is attached and engaged is fixed with a fixture by abutting both side end surfaces thereof, and a cross-sectional view of the engagement portion at the joint portion is substantially omitted. An object of the present invention is to provide a joint structure of a wall formed by fitting a T-shaped joint cover.
