Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a corner waterproof member for waterproofing a corner (corner) of a frame such as a skylight provided so as to project from the surface of a roof.

[0002]

2. Description of the Related Art The roof of a house or the like may be provided with a member such as a skylight that projects from the roof surface. In this case, the frame body of the skylight is provided so as to project on the surface of the roof plate (planar member), but it is necessary to make waterproof between the frame body and the plate.

Conventionally, as a technique for achieving this waterproofness, for example, Japanese Utility Model Publication No. 62-52618 and Japanese Utility Model Publication No. 62-5412.
There is one as shown in Japanese Patent Publication No.

On the other hand, the applicant of the present application, as shown in FIG. 3, has a base portion 2 fixed to the surface of the flat member 1 and a flange shape which is bent from the base portion 2 as an excellent waterproof property. And a fixing portion 5 fixed to the surfaces 4 of the two standing wall portions of the frame body forming the corner portions of the frame body 3, and the waterproof material 6 is attached to the surface of the fixing portion. I have already created 7.

[0005]

It has been demonstrated that the corner waterproofing member constructed as described above satisfies the required waterproofing performance, but on the other hand, the base 2 and the fixed portion 5 are Since it is integrally formed, a tensile load or a twist is likely to be generated in the entire corner waterproofing member 7 due to the mounting work at the time of construction (see the deformed state shown by the chain double-dashed line in FIG. 3), and as a result, the corner C There is concern that there may be damage such as cracks.

The present invention has been made in order to eliminate such a concern, and breakage such as cracks at the corners due to tensile load and twist that are likely to occur in the entire waterproof member for the corner due to mounting work at the time of construction. It is an object of the present invention to provide a waterproof member for a corner portion that is less likely to occur.

[0007]

In order to solve the above-mentioned problems, a corner waterproofing member according to the present invention is designed to waterproof the periphery of the corner of a frame provided on the surface of a flat member. A base portion fixed to the surface of the plane member, and a fixing portion that is bent from the base portion to have a flange shape and fixed to the surfaces of the two standing wall portions of the frame body forming the corner portion. In the waterproof member for the corner part, in which the waterproof material is attached to the surface of the fixed part, the cross section and the vertical cross section are L-shaped, and the fixed part is fixed to the upper surface of the base part and the surface of the fixed part. It is characterized in that a reinforcing member for reinforcing the corner portion of the fixed portion from the waterproof material side is provided.

[0008]

According to the waterproof member for a corner portion of the present invention, the cross section and the vertical section are L-shaped and fixed to the upper surface of the base portion and the surface of the fixed portion, and the corner portion of the fixed portion is made of the waterproof material. Since a reinforcing member is provided to reinforce from the side, the strength against the load that expands and narrows the fixed part and the torsional load at the corners is increased in the three-dimensional direction, depending on the mounting work during construction. It is possible to reduce the risk of breakage such as cracks at the corners.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of a waterproof member for a corner portion according to the present invention will be described below with reference to the drawings.

First, the structure will be described. In addition, about the element which overlaps with the prior art shown in FIG. 3, only a code | symbol is attached and detailed description is abbreviate | omitted.

In FIG. 1, reference numeral 11 denotes a corner waterproof member, which is a base portion 13 fixed to the surface of a roof plate 12 as a flat member, and a fixing portion 14 which is bent from the base portion 13 to form a flange shape. It has and.

Reference numeral 15 denotes a reinforcing member which reinforces the corner portion (broken portion) of the fixing portion 14 from the waterproof material (the member indicated by reference numeral 6 in FIG. 3) side, and is a molded product of vinyl chloride. There is.

This reinforcing member 15 is, as shown in FIG.
The cross section and the vertical section are L-shaped, and they are tightly fixed to the upper surface of the base portion 13 and the surface of the fixing portion 14 of the corner waterproof member 11 with a reinforcing adhesive.

According to the corner waterproof member 11 having such a structure, the upper surface of the base portion 13 and the fixed portion 1 are provided.
4 is provided with a reinforcing member 15 having an L-shaped cross-section and a vertical cross-section that are closely fixed to the surface of 4 to reinforce the corners of the fixing portion 14 from the waterproof material side, so that the fixing portion 14 can be expanded or narrowed. The load and the strength against the torsional load at the corners are increased in the three-dimensional direction, and it is possible to minimize the risk of breakage such as cracks at the corners due to mounting work during construction.

The present invention is not limited to the above-mentioned embodiments, and design changes made by those skilled in the art are also included in the technical scope of the present invention. For example, although vinyl chloride is mentioned as the material of the reinforcing member 15 in the above-mentioned embodiment, it may be made of stainless steel. The corner waterproofing member can be widely applied not only around the roof but also at places where waterproofing is required.

[0016]

As described above, according to the corner waterproofing member of the present invention, the cross section and the vertical cross section are L-shaped, and the corner waterproofing member is fixed to the upper surface of the base portion and the surface of the fixing portion. Since the reinforcing member for reinforcing the corner portion of the fixed portion from the waterproof material side is provided, the strength against the load that expands or narrows the fixed portion and the torsional load at the corner portion is increased in the three-dimensional direction. Therefore, there is an effect that it is possible to suppress a possibility that a breakage such as a crack occurs in a corner portion due to an attachment work at the time of construction.
