No. 7). This waterproof member is formed so as to cover the joint surface between the outer wall and the waist wall, and is specifically configured in the shape as shown in the publication.

That is, a rectangular horizontal plate and a vertical plate projecting from a L-shaped flange are formed by stacking two waterproof members. By attaching such a waterproof member, it is attempted to prevent rain from leaking from a waist wall attachment portion such as a balcony protruding from the wall surface.

[0004]

However, the above-mentioned conventional waterproof member can be applied to the waist wall protruding from the intermediate wall surface of the outer wall, but if this is used when the waist wall is attached to the protruding corner of the outer wall, the flange will be formed. It was out of the outer wall and could not be used. In this case, the two flanges are arranged at right angles along the projecting corners, and even if the waterproof member is rotated and inverted, the horizontal plate and the vertical plate that overlap each other are rectangular, so the horizontal surface where the waterproof member overlaps on the upper surface of the waist wall. The length of the boards in the protruding direction from the wall surface was different, which resulted in unevenness and bad appearance.

The present invention has been made in consideration of the above-mentioned prior art, and can be attached not only to the intermediate wall surface but also to the waist wall protruding from the projecting corner, and the rain at the corner of the wall surface opening portion. The purpose is to provide a waterproof member that can be used as a finish.

[0006]

In order to achieve the above object, according to the present invention, a plate-like flange having an L-shaped inner edge and an outer edge, and two edges on the inner edge side of the flange are perpendicular to the flange surface. In a waterproof member having a horizontal plate and a vertical plate that are bent and continuous to each other, the waterproof member is characterized in that the horizontal plate and the vertical plate have a square shape.

According to this structure, two waterproof members are combined and one of the waterproof members is rotated or turned upside down according to the shape of the waist wall projecting from the projected corner of the outer wall or the intermediate wall surface to be horizontal even if combined. Since the four sides of the plate and the vertical plate are the same, the projection length from the wall surface is the same whether the horizontal plate or the vertical plate is vertical or horizontal, so that the projection of the horizontal portion where the two waterproof members overlap is projected from the wall surface. Since the lengths are the same, it is possible to install it nicely on the base part of the waist wall mounting without creating a step.

In a preferred configuration example, there is a waterproof structure for a mounting portion of a waist wall projecting from a projecting corner of a building, in which two waterproof members are arranged with their flanges at right angles and at the same time between horizontal plates. And waterproofing members are combined so as to cover the upper surface of the waist wall and are attached to the waist wall mounting portion.

According to this structure, the waterproof member according to the present invention is reversed even when the waist wall is attached to the corner of the building,
By rotating and assembling, it is possible to prevent the occurrence of unevenness due to the overlapping of the waterproof members, and it is possible to install the waterproof member along the protruding corner without protruding.

In a preferred configuration example, a waterproof structure of a waist wall protruding from an intermediate wall surface of a building outer wall, wherein two waterproof members are arranged on the same surface so that their flanges cover the wall surface, It is characterized in that the horizontal plates are overlapped with each other to cover the upper surface of the waist wall, and that both waterproof members are combined so as to cover the upper side surface of the waist wall with each vertical plate and attached to the waist wall mounting portion.

According to this structure, even when the waist wall is attached to the intermediate wall surface of the building outer wall, the waterproof member according to the present invention is inverted and rotated to be combined with each other. It can be installed aesthetically without causing any problems.

In a preferred configuration example, there is a waterproof structure at a corner of an opening of a building wall body, in which two waterproof members are arranged such that their flanges are parallel to each other to sandwich the wall body and the horizontal structure. It is characterized in that the plates and the vertical plates are overlapped with each other, and both waterproof members are combined and disposed at the opening corners so as to cover the surfaces of the corners in the width direction of the wall body.

According to this structure, even at the corners of the opening of the building wall, the waterproof member according to the present invention is inverted and rotated to be combined with each other, so that the occurrence of unevenness due to the overlapping of the waterproof members occurs. It can be installed without looking good.

In a preferred configuration example, there is a waterproof structure for the upper edge of the inside of the bent corner portion of the veranda wall body, in which one of the waterproof members has its flange portion as the upper surface and the horizontal plate and the vertical plate form a corner. It is characterized in that it is arranged so as to cover the inside of the portion.

According to this structure, the inside of the corner can be waterproofed by using the waterproof member according to the present invention even at the corner where the waist wall is bent.
