DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waterproof structure and a waterproof panel applied to a sloped roof made of RC (Reinforced Concrete), ALC (Lightweight Cellular Concrete) or the like of a building or a house.

[0002]

2. Description of the Related Art Conventionally, for waterproofing a roof of a sloping roof of a building or a house, a waterproof sheet made of a soft synthetic resin is used to avoid roofing with hard tile materials such as clay tiles, cement tiles, glass tiles, and metal tiles. Roof waterproofing using a sheet waterproofing method of laying this so as to cover the entire surface of the roof foundation is often adopted. In this method, a waterproof sheet is entirely or partially bonded to the upper surface of a roof base using an adhesive or a fixing tool so as to cover the entire surface of the sloped roof.

[0003] The waterproofing of the roof using the waterproofing sheet is carried out by an adhesion method in which the waterproofing sheet is entirely bonded to the upper surface of the frame via an adhesive, or a waterproofing sheet is provided with a fixing plate on the head. It is installed in a water-tight state by a so-called insulating method in which a nail-like fixing tool is provided to fix and bond the upper surface of the fixing plate or a waterproof sheet is pressed and fixed on the lower surface of the fixing plate of the same fixing device.

[0004] However, any of the above waterproof roofs on a sloping roof is too flat and unattractive, and in order to reduce the number of man-hours during construction, it is not rigid and difficult to handle. Due to the tendency to use a waterproof sheet having a large area, the installation work is inevitably large, and the work cost is rather increased.

[0005] In order to solve such a drawback of the conventional roof waterproofing, a plurality of waterproof sheets having a relatively small area are sequentially laminated on side surfaces adjacent to each other in the lateral direction of the sloping roof, and the sloping roof is provided in the sloping direction. After laminating at the upper and lower edges of the waterproof sheet and joining each other on the roof foundation so that each laminated portion of the side edge is positioned in a staggered manner in adjacent upper and lower rows,
2. Description of the Related Art A waterproof structure of a sloped roof has been proposed in which a step portion at each side edge and upper and lower edges is filled with sealing materials having different colors. A specific example of such a structure is described in, for example, JP-A-63-30
No. 0158.

However, according to the above-described proposal, the installation work is easily improved in terms of aesthetics and the use of a waterproof sheet having a relatively small area. In order to form the waterproof sheets in a regular arrangement, it is difficult to position the waterproof sheets relative to each other due to the weakness of the waterproof sheet itself, the means of joining to the roof base, the means of overlapping the waterproof sheets, etc. However, it takes a long time to join or overlap, and the installation operation is still troublesome. This tendency is remarkable especially when the slope of the sloping roof is large, and the installation work is extremely difficult.

[0007]

Further, the waterproof panel may be colored in an arbitrary color or may have an arbitrary color pattern on the surface. In addition, the back surface of the waterproofing panel is usually flat and does not require a color pattern.

Next, the fixing member attached to the side of the waterproof panel according to the present invention will be described. The fixing member is made of a plate-shaped piece made of a synthetic resin steel plate. Is usually adhered to the back surface of the waterproof panel by an adhesive means or a fusing means except for a fixed edge portion. As the synthetic resin steel plate applied to the fixing member, a commercially available synthetic resin steel plate is applied. For example, in a case of a polyvinyl chloride steel plate, its thickness is usually in the range of 0.5 to 2.0 mm, and the thickness of the vinyl chloride resin layer is It is approximately 0.1 to 0.9 mm. in this case,
At the fixing edge of the fixing member, a fixing tool for inserting the waterproof panel more accurately and easily is inserted, and at least one insertion hole for embedding the fixing tool in a roof base is provided. Shall be kept.
