Anti-slip leakproof roofing sailcloth for building
A roofing sailcloth for a building includes a substrate of woven cloth, anti-slipping material woven to the substrate to increase surface roughness of a face of the substrate, and a leakproof layer bonded to the other face of the substrate. The roofing sailcloth is waterproof and leakproof and has high tensile strength and high tearing strength. Furthermore, the roofing sailcloth has improved anti-slipping effect to allow a worker to walk on the sailcloth safely and easily. Furthermore, the roofing sailcloth is light and allows easy transport to improve constructing efficiency. Furthermore, the roofing sailcloth possesses excellent anti-aging properties.
1. Field of the Invention
The present invention relates to roofing sailcloth for a building and, more particularly, to anti-slip leakproof roofing sailcloth mounted on a roof of a building and including anti-slipping material woven in a warp direction and/or a weft direction during weaving of the sailcloth.
2. Description of the Related Art
To construct a building by wood and/or bricks in a cold zone, a layer of roofing sailcloth is placed on the roof before making the cement roofing or installing roofing tiles made of cement or composite material. The roofing sailcloth allows easy construction and improves leakproofness and temperature-maintaining capability of the resultant building. The roofing sailcloth includes plastic films or woven plastic cloth on two faces thereof. Workers on the roofing sailcloth are liable to slip on the outer faces of the plastic materials (mostly polyethylene or polypropylene). The smooth outer faces of the sailcloth also result in difficulty in making the cement roofing and in installing the roofing tiles.
SUMMARY OF THE INVENTIONAn objective of the present invention is to provide roofing sailcloth that is waterproof and leakproof and that has high tensile strength and high tearing strength.
Another objective of the present invention is to provide leakproof anti-slip roofing sailcloth that provides improved anti-slipping effect, allowing a worker to walk on the sailcloth safely and easily.
A further objective of the present invention is to provide roofing sailcloth that is light and that allows easy transport to improve constructing efficiency.
Still another objective of the present invention is to provide roofing sailcloth that possesses excellent anti-aging properties.
A roofing sailcloth for a building according to the preferred teachings of the present invention includes a substrate of woven cloth, with the substrate including a first face and a second face opposite to the first face; anti-slipping material woven to the substrate to increase surface roughness of the first face of the substrate; and a leakproof layer bonded to the second face of the substrate.
In a preferred form, the anti-slipping material is woven in at least one of a warp direction and a weft direction of the substrate. The anti-slipping material includes fibers, yarns, or flat yarns having a napped surface. The leakproof layer is made of thermoplastic elastomer or plastic material. A plurality of protrusions may be bonded to or printed on an outer face of the leakproof layer. The protrusions are made of thermoplastic elastomers and form an anti-slipping layer.
Other objectives, advantages, and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
The roofing sailcloth according to the preferred teachings of the present invention is waterproof and leakproof and has high tensile strength and high tearing strength.
