Then the inside corner is formed of the vertical surface 122 on one side and the vertical surface 123 for forming the inside corner, and the vertical surface 123 for forming the inside corner is erected over the plane 11.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a corner portion of a building flat portion such as a roof roof plate and two building side elevations forming a projected corner portion of a skylight frame or the like protruding from the roof roof plate. Also, the present invention relates to a corner waterproof member suitable for use in waterproofing (raining) at a corner portion between a building surface portion such as a wall surface or the like and a building flat portion such as a floor that are substantially orthogonal to each other and form an entering corner portion. .

2. Description of the Related Art When a skylight or the like is provided on a roof of a house or the like, a frame body of the skylight is provided so as to project from the roof roof plate, and rainwater or the like is provided between the frame body and the roof plate. It is necessary to ensure the waterproofness of the protruding portion of the frame so as not to enter. Conventionally, as a waterproof structure of such a skylight,
For example, Japanese Utility Model Laid-Open No. 62-52618 and Japanese Utility Model Laid-Open No. 62-62-
It is disclosed in Japanese Patent No. 54125.

In the former structure, a water bar having a substantially inverted L-shaped cross section is provided over the entire width of the side surface of the skylight frame, which is projected from the roof, slightly above the side surface on the water side. A draining board is laid on the roof on the water side of the frame body, and the upper end portion of the draining piece raised from the water side end portion of the water draining board along the side surface of the window frame body has the above-mentioned substantially cross section L
It is fitted in the groove of the water-repellent part of the character shape.

In the latter structure, the drainage plate laid on the water side of the skylight is provided with the upwardly projecting ridge so as to incline to the water side from the center to both sides. However, in such a conventional waterproof structure, it is only necessary to provide a water return portion on the upper side of the water, or to provide a ridge on the draining section, and to bend rainwater flowing from the upper side of the water from the skylight frame body portion. , The reliable waterproofness cannot be obtained. In particular, it is difficult to obtain reliable waterproofness at the corner portions of the roof roof plate and the skylight frame body protruding from the roof plate.

Therefore, in order to eliminate these drawbacks of the waterproof structure, a waterproof member for a corner described in Japanese Patent Laid-Open No. 4-203152 has been proposed. This Japanese Patent Laid-Open No. 4-203
In the waterproof member for a corner described in Japanese Patent Publication No. 152, a rising portion is erected on a flat surface portion, and the rising portion is composed of two vertical surface portions that are substantially orthogonal to each other, and these two vertical surface portions form a projecting corner portion. In addition, a waterproof material flat surface portion is attached to a building flat surface portion such as a roof roof plate, and two vertical surface portions that are substantially orthogonal to each other are substantially orthogonal to a building vertical surface portion such as a skylight frame body portion that forms a projecting corner portion. Two
It is intended to secure the waterproofness at the corner between the flat part of the building and the elevation part of the building by attaching it to the surface.

[0006]

However, in the waterproof member for a corner described in Japanese Patent Laid-Open No. 4-203152, the flat plane portion of the building such as a roof plate and the vertical portion of the building such as the skylight frame body are substantially orthogonal to each other. Waterproofness can be ensured at the corners of the building elevation that forms the projected corner, but it is not useful for ensuring waterproofness at the entry corners where the building elevations are almost orthogonal. .

The present invention has been made by paying attention to the problems in the conventional waterproof material for corners,
The purpose is to solve the above-mentioned problems in the conventional waterproofing material for corners, and even if the building elevation is an exit corner where the building elevations are almost orthogonal, it is an entrance corner where the building elevation is almost orthogonal. However, it is to provide a corner waterproof member that can be used in any case.

[0008]

In order to solve the above-mentioned problems, in the corner waterproof member of the present invention, a rising portion is erected on a flat surface portion, and the rising portion is composed of two substantially perpendicular rising portions. In the waterproof member for a corner portion, in which the projected corner portion is formed by the two raised surface portions and which is made of a waterproof material, the standing member for forming the entering corner portion is formed from the side edge of one of the raised surface portions of the raised portion. The surface portion is extended, and an entering corner portion is formed between one of the rising surface portions and the rising surface portion for forming the entering corner portion, and the rising surface portion for forming the entering corner portion is erected on the flat surface portion. It is characterized by being present.

In the present invention, the waterproof material is not particularly limited as long as it is a waterproof material, and for example, a hard vinyl chloride resin,
A synthetic resin such as polyethylene or polypropylene, an asphalt waterproof paper obtained by impregnating paper with asphalt, a waterproof material such as stainless steel, copper or aluminum can be used.

[0010]

According to the present invention, the upright portion for forming the inward corner portion extends from the side edge of one of the two upright surface portions of the upright portion. When the building elevation forms the projecting corner, the entering corner is formed between the forming elevation and the entering corner forming elevation is erected on the flat surface. Removes the elevation for forming the entering corner of the waterproof member of the present invention,
The flat surface portion of the waterproof member of the present invention is attached to the flat surface portion of the building, and the two elevation portions forming the projected corner portion of the waterproof member of the present invention are attached to the vertical portion of the building, whereby the flat portion of the building and the flat portion of the building are formed. The waterproofness of the corners of the building can be ensured, and when the building elevation forms an entry corner, the other elevations are left, leaving the elevation for forming the entry corner of the waterproof member of the present invention. Is removed, and the flat surface portion of the waterproof member of the present invention is attached to the flat surface portion of the building, and the two elevation portions that form the entering corner portion of the waterproof member of the present invention are attached to the building elevation portion to form a building elevation portion. It is possible to ensure waterproofness at the corner with the flat surface of the building.

Therefore, in the waterproof part member of the present invention, in either case, whether the building elevation is substantially orthogonal or the building elevation is approximately orthogonal, Can be used.
