Description

The present invention relates to a projecting corner structure when a wall body is formed by using a dry type wall material. More specifically, the present invention relates to a projecting corner structure of a dry wall material in a wall body in which horizontal makeup joints are formed by using the dry wall material in a laterally stretched manner.

[Conventional technology]

Conventionally, in order to form a projected corner using a dry wall material, for example, a projected corner material A having U-shaped insertion portions 2 on both side edges of a decorative surface portion 1 having a mountain-shaped cross section as shown in FIG. ', And the end portion of the dry wall material is inserted into the insertion portion 2 of the projected corner material A'. However, when a dry wall material B such as that shown in FIG. 3 is used as a dry wall material so as to be laterally laid to form a wall body, as shown in FIG. 10 (b), a projected corner material A'and a dry wall material B are formed. Voids β due to the makeup joint formed by the dry type wall material B are formed between them, leading to a decrease in waterproofness and corrosion of the wall base. Therefore, a caulking material is planted in the space β, but a large amount of caulking material is required, which leads to an increase in cost and the planting of the caulking material requires time and labor.

[Object of the Invention]

In order to eliminate such drawbacks, the present invention loads a waterproof material, which is a molded body having the same shape as the void formed between the corner material and the dry wall material, into the void and contacts the corner material of the waterproof material. At least one convex surface is formed on the surface that comes into contact with the surface, and a concave line is formed on the contact surface of the projected corner material, and the waterproof material is formed by the engagement of the convex stripe of the waterproof material and the concave stripe of the projected corner material. We propose a corner structure for dry type wall material that prevents misalignment and disengagement after loading, and greatly improves waterproofness and workability.
