Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an outer wall, and more particularly to an outer wall having an improved mounting structure for ceramic outer wall materials.

[0002]

2. Description of the Related Art On the outer wall of a building, a border (boundary member) is used as a decorative material to change the design.
Are being installed. The border is usually made of metal, and the shape of the portion exposed to the outside is given uniqueness or colored.

However, in the outer wall, a deep color tone and a glossy finish cannot be expressed only by the surface treatment of metal, and there is a limit in further improving the designability. In order to solve such a problem, the present inventors attach a ceramic-type outer wall material to a wall surface of a building to express a deep color tone and a glossy finish that cannot be produced by a metal surface treatment. We are developing an outer wall that can be improved and its design can be improved.

Incidentally, as a related technique, the actual fair 2-

However, in the above-mentioned outer wall, when applied to, for example, a curtain wall, the main member constituting the wall surface of the curtain wall is made of metal, and when strong wind is received, it is within an elastic range due to wind pressure. Although bending occurs, the ceramic outer wall material has almost no elasticity,
If an excessive force is applied to the ceramic outer wall material due to the bending of the wall surface, the ceramic outer wall material may be damaged. Further, since the wall surface and the ceramic-based outer wall material have different coefficients of thermal expansion, there is a risk that the ceramic-based outer wall material may be damaged by the stress generated by the difference in thermal expansion between the wall surface and the ceramic-based outer wall material.

The present invention has been made in consideration of the above circumstances, and it is possible to express a deep color tone and a glossy finish that cannot be obtained by surface treatment of metal, and to improve the designability. An object of the present invention is to provide an outer wall capable of preventing the ceramic outer wall material from being damaged due to the bending of the wall surface or the difference in thermal expansion from the wall surface and improving the durability.
