Description

[Detailed description of the invention] "Industrial application field" The present invention relates to a roofing material used on a base plate or a concrete roof surface.

[Related Art] In recent years, a lightweight and heat-insulating strip-like sheet 3 in which a surface layer 2 of a vulcanized rubber sheet is bonded to an upper surface of a synthetic resin foam layer 1 has come to be used. However, as shown in FIG. 7, the band-shaped sheet 3 has its side edges abutted, and a vulcanized rubber tape 8 is adhered to the upper surface via a double-sided adhesive tape 9 over both sides of the abutted edge to form the foam layer 1. 1, it was necessary to prevent water from leaking to the abutment surfaces 3 ', 3'. Such a vulcanized rubber tape 8 not only impairs the appearance of the roof but also easily peels off, and it is difficult to align the center line of the vulcanized rubber tape 8 with the abutment surfaces 3 ′ and 3 ′ during construction. ', 3'
Is easy to be exposed, and not only skill is required for long-distance construction, but also it is difficult to construct a stepped roof because the foamed layer 1 is exposed when the side edges are polymerized.
There was a problem that a space was created and water was easily leaked.

"Problem to be solved by the invention" The purpose of the present invention is to obtain a lightweight and highly heat-insulating roofing material that can be easily abutted at the side edges, has excellent waterproof properties, and can be easily constructed.

"Means for solving the problem" In order to achieve the above object, the present invention relates to the above-mentioned foam layer on the lower surface of the surface layer along the side edge of the roofing belt-like sheet formed by bonding the surface layer to the upper surface of the synthetic resin foam layer. Instead, the edge material is joined, the side surfaces of the edge material can be abutted on the roof surface, and the adhesive layer can be joined to the lower surface of the edge material so that the roof material is vulcanized rubber. The roofing material described in the above invention is constituted by the roofing material according to the first or second invention in which the edge material is unvulcanized rubber.

[Operation] Accordingly, as shown in FIG. 2, a vulcanized rubber tape 11 is stretched in a straight line on the surface of the roof surface 10 such as a base plate or concrete with an adhesive, and the edge members 4, 4 are formed on the upper surface of the tape 11. The upper surfaces of the strip-shaped sheets 3 and 3 can be connected substantially flat by being brought into contact with each other and bonded with the adhesive layer 5. When the edge members 4 and 4 are unvulcanized rubbers 7, the abutment surfaces 4 'and 4' of the edge members 4 and 4 are adhered by their adhesiveness, so that the entry of rainwater is stopped at the abutment surfaces 4 'and 4'. (Figure 2).

"Embodiment" An elastic surface layer 2 made of vulcanized rubber is adhesively bonded to an upper surface of an elastic or flexible foam layer 1 made of a synthetic resin foam by an adhesive, so that a belt-shaped sheet 3 for a roof can be formed. A cutout portion of the foam layer 1 is provided at a side edge of the sheet 3, and the cutout portion is formed by bonding an edge material 4 made of a vulcanized rubber 6 or an unvulcanized rubber 7 with an adhesive. The thickness of the material 4 is substantially equal to the thickness of the foam layer 1. Then, an adhesive layer 5 is formed on the lower surface of the edge member 4 with a double-sided adhesive tape or the like, and the adhesive lower surface is covered with a release paper 5 'to form a product. The edge material 4 is provided on one side edge or both side edges of the band-shaped sheet 3.

[Effects of the Invention] Since the present invention is constructed as described above, not only is it possible to obtain a very lightweight roofing material having excellent heat insulation properties, but also to perform abutment construction of the seam of the side edge portion of the strip-shaped sheet 3 having good waterproofness. Not only can it be done easily, but also the roof can be reinforced by the abutment construction.
