Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a roof waterproof belt used when roofing materials are overlapped and installed in a row.

When constructing large roofs for factories, etc., folded roofing materials are stacked one on top of the other. During such construction, in order to shorten the length of the roofing materials and streamline transportation and construction work, the longitudinal ends of the roofing materials are overlapped and connected in the span direction of the roof from the ridge to the eaves. things are being done. Therefore, it is necessary to prevent rainwater from entering through the heavy parts of the roofing material. The present invention provides a waterproof bell that can effectively prevent the infiltration of rainwater.

The present invention will be described below based on illustrated embodiments. FIG. 1C is a perspective view of a waterproof belt 1 according to an embodiment of the present invention. This waterproof belt 1 consists of a horizontally long flat plate part 2, a plurality of protrusions 3 protruding from the upper surface of the flat plate part 2, and an adhesive layer 4 attached to the lower surface of the flat plate part 2. The flat plate portion 2 and the protruding stripes 3 are formed by integrally molding a flexible material such as soft rubber, soft plastic, or closed-cell foamed plastic. In this embodiment, the protrusion 3 is formed to have a triangular cross section so that it can bend freely depending on the direction of pressure. The flat plate portion 2 has left and right end portions rounded to a large diameter, and the adhesive layer 4 is provided so as to be fitted between the large diameter portions 5. This adhesive layer 4 adheres to the roofing material due to its viscosity and prevents the waterproof belt 1 from slipping.

The waterproof belt 1 as described above is used so as to be sandwiched between the overlapped parts of the roofing materials 11 and 12, as shown in FIG. That is, when overlapping the longitudinal ends of the negative roofing material 11 with the longitudinal ends of the other roofing materials 12, the protrusions 3
Roofing materials 11, 12 so that
It is sandwiched between the ends of. By being sandwiched between the overlapping parts, the waterproof belt 1 is bent along the cross-sectional shape of the roofing material 11, 12, and the adhesive H4 is tightly attached to the upper surface of the lower roofing material 11, preventing rainwater from entering. Furthermore, although the protrusions 3 contact the lower surface of the upper roofing material 12, since the protrusions 3 are orthogonal to the longitudinal direction of the roofing material, rainwater is prevented from penetrating between the roofing material 12 and the protrusions 3. Therefore, the infiltration of rainwater can be effectively prevented, and the roof can be constructed by connecting roofing materials in the span direction.

FIG. 3 shows a perspective view of another embodiment of the invention. In the waterproof belt 1 of this embodiment, the triangular protrusion 3 has a flat plate portion 2.
The protrusions 3 are formed on both the upper and lower surfaces of the roof member 9, and in use, the protrusions 3 come into contact with both the upper and lower roof members 11 and 12. Note that the protrusion 3 is not limited to a triangular shape;
It may be rectangular or arcuate.

As described above, according to the present invention, since the waterproof tube 4 is brought into close contact with the overlapping portion of the longitudinal end of the root material, it is possible to prevent rainwater from entering from the overlapping portion.

Therefore, since the roofing materials can be connected in the span direction of the roof, the length of the roofing materials can be shortened, which is effective in making construction work more efficient and transportation and storage easier.
