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 improve the efficiency of transportation and construction work, the longitudinal ends of the roofing materials are overlapped and installed in a row in the span direction of the roof from the ridge to the eaves. is being carried out. Therefore, it is necessary to prevent rainwater from entering through the overlapped portions of the roofing material. The present invention provides a waterproof belt that can effectively prevent such rainwater from entering.

Hereinafter, the present invention will be specifically described based on illustrated embodiments. FIG. 1 is a perspective view of an embodiment of the present invention. The waterproof belt 1 of this embodiment is composed of a horizontally long flat plate part 2 and a plurality of protrusions 3 projecting from the upper surface of the flat plate part 2 in the longitudinal direction. This flat plate part 2
Since the protrusion 3 is entirely made of a flexible magnetic rubber sheet, it itself has an adhesion function. That is, after the waterproof belt 1 is bent or otherwise deformed and attached to the roofing material, it does not return to its original state. This magnetic rubber sheet is manufactured by dispersing magnetic powder in a rubber raw material or a plastic raw material such as urethane.

Such a waterproof band 1 is inserted into the overlapping part of the roof material to prevent rainwater from leaking through the overlapping part. FIGS. 2 and 3 are a perspective view and a sectional view showing this construction state.

The waterproof belt 1 has protrusions 3 disposed at longitudinal ends 13 and 14 of roofing materials 11 and 12 having a folded plate structure so as to be perpendicular to the longitudinal direction of the roofing material, and along the folded plate structure of the roofing material. It is pasted in a deformed state. To construct the roof, the front end of the roofing material 12 is overlapped with the rear end 13 of the roofing material 11 to which the waterproof belt 1 is attached, and the roofing material is installed in the span direction of the roof from the ridge to the eaves. are set up consecutively.
Here, the roofing material 12 is placed on the ridge side of the roof, and the roofing material 11
is located on the eave side of the roof. By such overlapping, the waterproof belt 1 is interposed in the overlapping portion of the roofing material. With this interposition, the lower surface of the waterproof belt 1 is brought into close contact with the upper surface of the roofing material 11, and the protrusion 3 is brought into close contact with the lower surface of the roofing material 12, so that the roofing material 11,
Infiltration of rainwater from the polymerized portion of No. 12 is prevented.
The waterproof belt and the roofing material are brought into close contact with each other due to the attractive force of the magnet. Since the entire waterproof sheet 1 is made of a magnetic rubber sheet, it will not restore its original shape, and since the waterproof sheet 1 maintains the cross-sectional shape of the roofing material and adheres closely to the roofing material, the waterproofing effect will not deteriorate over time. . Although the protrusions 3 are perpendicular to the longitudinal direction of the roofing material, they are brought into close contact with the lower surface of the roofing material 12 by the pressing force and maintained in a close contact state, so that leakage of rainwater can be effectively prevented. Therefore, it is possible to install short roofing materials in a row in the span direction of the roof, and there is no need to use long roofing materials, so it is possible to save labor and speed up the construction work.

Note that the protrusion 3 may have a triangular cross section, or may have a circular arc cross section, etc., and various other changes are possible.

As described above, according to the present invention, since the waterproof belt is brought into close contact with the overlapping portion of the longitudinal end portion of the roof material, it is possible to prevent rainwater from entering from the overlapping portion. Therefore, since the roofing materials can be connected in a row in the span direction of the roof, the length of the roofing materials can be shortened, which is effective in improving the efficiency of construction work and facilitating transportation and storage work.
