Abstract

PROBLEM TO BE SOLVED: To prevent corrosion of an inner wall and an internal facing material by infiltration of rainwater with easy execution work by constituting an external corner outer wall of an external corner outer wall material and an L-shaped backing material having the same shape as this. SOLUTION: This external corner outer wall is composed of an external corner outer wall material 4 and an L-shaped backing material 1 having the same shape as this. That is, the backing material 1 composed of a corrosion resistant/heat resistant metallic thin plate or a synthetic resin thin plate which is rich in adhesion and joins to an L-shaped corner top part 2 easily causing a crack of the outer wall material 4, is arranged inside the projected corner wall material 4. The backing material 1 is adhered to and integrally fixed to the inside of the outer wall material 4 by protrusively arranging a calking material 3 or applying an adhesive to the L-shaped corner top part 2 of the backing material 1. Therefore, corrosion of an inner wall and an internal facing material by infiltration of rainwater can be prevented with easy execution work.

Description of the Related Art With respect to a fireproof outer wall material of a building, a corner outer wall S formed in an L shape in FIG. 7 is attached to a corner C portion of an outer wall M shown in FIG. Regarding the corner outer wall material, fired fire-resistant wall material flat plates are abutted in an L shape, and an adhesive is applied to a joint portion thereof to be fixed as a corner outer wall material. The outer wall material for corners is coated with an adhesive on the inside and joined to the inner wall material and interior material to be integrally formed, but conventionally the adhesive is applied to the inside of the outer wall material for corners and directly attached to the interior material. Therefore, at the joint with the interior material, for example, the pillar, there is a gap due to the bending of the pillar and a gap between the corner material of the outer wall due to dimensional error in design, and after building the building, the L-shaped part of the outer wall of the corner material and the painted surface Rainwater and dust penetrate through the cracks and cracks that occur, causing a problem that the inner wall or the interior material is corroded and worn, thereby lowering the durability of the building.

In FIG. 1, reference numeral 1 denotes a perspective view of a base material of the present invention. The material is a corrosion-resistant and strong metal plate such as a stainless steel or a corrosion-resistant steel plate, or a heat-resistant extruded material made of a hard plastic of 0.4 mm to 1.5 mm. Optimally, it is formed into a thin plate having a thickness of about 0.5 mm, and is formed into an L-shape having the same shape as the outer wall material for the outer corner.
Numeral 2 is a corner of the base material, and numeral 3 is a caulking material bulging at the corner. The caulking material 3 protrudes in the shape of a rib above the corner 2. The raised part of the caulking is 10mm to 18m
Raise to about m. As shown in FIGS. 2 and 3, the caulking material is formed by bonding and bonding the base material 1 to the inside of the outer corner material 4 for the outside corner.
It is integrally bonded to the outer wall material 4 and fixed with nails or the like (not shown). The caulking 3 raised on the corner 2 of the base material 1 is shown in FIG.
As shown in the figure above, it extends to both sides of the corners of the base material and watertightly bonds between the outer wall material for corners and the base material so that rainwater etc. invades even if there is a gap between the interior material, for example, the pillar I will not do it.
Instead of the caulking material, a method of appropriately applying a width to the L-shaped portion of the base material with another adhesive may be used. In addition, since the base material is integrally attached to the outer corner material for the outer corner, it has the effect of reinforcing the outer corner portion and protecting the inner wall material.

法上大きな利点をもたらす効果がある。According to the present invention, as described above, the conventional construction of a building using only the outer wall material for a corner is difficult to corrode the inner wall and the interior material due to intrusion of rainwater. A metal plate formed of a thin plate inside the inside or a base material formed of a strong water-resistant and heat-resistant synthetic resin thin plate is adhered with a caulking material or an adhesive to form an integral exterior wall material method. The difficulty is solved by the watertight action of the base material of the invention and the caulking material attached to the base material. In addition, there is an advantage that the base material is formed of a thin plate having a thickness of 0.4 mm to 1.5 mm and can be provided at a low cost and light weight.
For example, there is no need to pre-drill a nail hole and fix it to the outer wall material, and the outer wall material and the base material can be directly fixed to the building interior material, so that the construction is easy and the labor saving of the cornering method is not hindered. In addition to durability, strength and non-water infiltration of the outer corner for the outside corner are achieved by an unprecedented effect, and there is an effect that brings great advantages in the outer wall construction method for the outside corner.
