Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is intended to prevent water leakage from a roof. For example, after construction of a waterproof roofing sheet for roof, there was rainfall before construction of roofing roofing materials such as roof tiles. The present invention also relates to a construction method and construction structure of a waterproof waterproof roofing sheet for a roof capable of surely preventing water leakage.

[0002]

2. Description of the Related Art Conventionally, a waterproof waterproof roofing sheet for a roof has been attached for the purpose of waterproofing, and it has been laid in a state in which a lap margin is sequentially provided from the eaves side of a sloped roof to the ridge side. At that time, staples were driven into the overlapping portion to fix the waterproof waterproof roofing sheet to the base plate.

[0003] The stapling results in punching as many holes in the waterproof waterproof roofing sheet for the roof, which impairs waterproofness by that amount. In such a case, even if rainwater entered the waterproof underlay sheet for roof, the leaked water from the staple holes was hardly recognized because the rainwater would be in a flow state.

As a result, even if the waterproof performance is deteriorated to some extent by the staple holes, once roofing material such as roof tiles is constructed, it is possible to fulfill the function as a roof, after the completion of the house. Problems were rare.

In addition to the above-mentioned stapling construction method, an adhesive layer and a release paper for covering the adhesive layer are provided on the back surface of the waterproof waterproof roofing sheet for roof, and the release paper is peeled off to the base plate by the adhesive force of the adhesive layer. There was also a construction method of sticking.

[0006]

However, in the above-mentioned conventional technique, that is, according to the construction method by stapling, the roof roofing material such as roof tiles is constructed after the waterproof waterproof roof sheet for roof is constructed. Heavy rain in front (50m
m / H), water was often leaked through the staple holes through the staple holes.

Further, according to the method of sticking the release paper to the base plate with the adhesive layer provided on the back surface of the waterproof waterproof roofing sheet for roof, it takes a lot of time to remove the release paper, and the release paper is treated after the peeling. Problem has occurred. In addition, since the adhesion by the adhesive layer does not work for re-adhesion, careful construction is required, and it is difficult to say that the workability is good. Another drawback is that the waterproof roofing sheet for roof itself is expensive.

The present invention has been made in view of the above circumstances, and its purpose is to prevent water leakage from the roof. For example, after the roof waterproof waterproof roof sheet is applied, roof tiles, etc. It is an object of the present invention to provide a construction method and construction structure of a waterproof waterproof roofing sheet for a roof, which can maintain a reliable waterproof performance even if there is rainfall before the construction of the roofing roof material.

[0009]

In order to achieve the above object, in the method for constructing a waterproof waterproof roofing sheet for a roof according to the present invention, as described in claim 1, a base plate placed on a roof is used. A belt-shaped first surface fastener is arranged on the upper surface along the roof slope with the sticking surface facing upward, and a second surface fastener of the second surface fastener provided on the back side of the waterproof waterproof roofing sheet for the roof with respect to the upper surface of the first surface fastener. By sticking the sticking surface, a waterproof waterproof roofing sheet for roof is laid on almost the entire upper surface of the base plate.

This eliminates the need for fixing with staples, which naturally eliminates water leakage from the staples. Further, it is possible to prevent the waterproof waterproof roofing sheet for a roof from breaking due to stapling.

Further, unlike the adhesion by the adhesive layer described in the prior art, not only the trouble of peeling the release paper does not occur, but also when it is misaligned, it can be redone. That is, the first surface fastener and the second surface fastener adhere to each other so that they can be easily reattached. While this can improve workability, it also has the disadvantage of easy peeling. The reason why such a material is used as a housing exterior material is based on the following technical idea.

That is, since the roofing roofing material is disposed on the upper portion of the waterproof waterproof roofing sheet for roof, it is hardly exposed to the outside air after the completion of the house construction. Therefore, the temporary adhesion for a limited time is sufficient to satisfy the adhesive force. Therefore, it is possible to sufficiently fulfill the function by attaching the first surface fastener and the second surface fastener.

The above-mentioned technical idea has not been given so far, and according to the conventional technical idea, the waterproof waterproof roofing sheet for roof and the base plate are connected at a stage before the roofing roofing material is arranged. It can be said that they are already tightly coupled, and are significantly different from the technical idea according to claim 1 of the present application.

Further, in the method for constructing a waterproof waterproof roofing sheet for a roof of the present invention, as described in claim 2, the roof waterproof waterproofing roof sheet laid on substantially the entire upper surface of the base plate is provided on the upper side. A roofing roofing material is arranged, and a fixing nail member that penetrates the roofing roofing material and the waterproof waterproof roofing sheet for roof from the upper side of the roofing roofing material and reaches the base plate is driven to combine the roofing roofing material and the base plate. May be.

In this case, the waterproof waterproof roofing sheet for roof is securely fixed by the roofing roof material. That is, since the roofing material is exposed to the outside air, it is firmly connected to the base plate by the fixing nail member. As a result, the roof waterproof underlay sheet sandwiched between the roof roofing material and the base plate is firmly fixed.

Further, in the construction structure of the waterproof waterproof roofing sheet for a roof of the present invention, as described in claim 3, the belt-shaped first surface is formed on the upper surface of the base plate arranged on the roof along the roof slope. By arranging the fasteners side by side with the sticking surface upward, and by sticking the sticking surface of the second surface fastener provided on the back side of the waterproof waterproof roofing sheet for the roof to the upper surface of the first surface fastener, the base plate A waterproof waterproof roofing sheet for the roof was laid on the entire upper surface of the.

In this case, the same operational effect as the operational effect according to claim 1 of the present application is provided.

Further, in the structure for constructing a waterproof waterproof roofing sheet for a roof of the present invention, as described in claim 4, the roof waterproof waterproofing roof sheet laid on substantially the entire upper surface of the base plate is provided on the upper side. A roofing roofing material is arranged, and a fixing nail member that penetrates the roofing roofing material and the waterproof waterproof roofing sheet for roof from the upper side of the roofing roofing material and reaches the base plate is driven to combine the roofing roofing material and the base plate. May be.

In this case, the same operational effect as the operational effect according to claim 2 of the present application is provided.
