CONSTRUCTION METHOD AND CONSTRUCTION STRUCTURE OF INCOMBUSTIBLE BUILDING MATERIAL

PROBLEM TO BE SOLVED: To solve the problem of causing separation or lift at the surface layer of a plate body after construction due to the brittleness of the surface layer of the backing plate body and low inter-layer strength because of adopting a method of bonding an incombustible building material using the plate body such as a calcium silicate plate or a cement perlite plate, as a general construction method as incombustible structure is demanded for the interior wall of a kitchen, a cooking room, a building or the like. SOLUTION: The brittleness of a backing plate body and low inter-layer strength are improved by applying a water reinforcing material, and a pressure sensitive adhesive double coated tape and an adhesive are jointly used to construct the incombustible building material. In this construction method, construction is simplified while realizing construction structure causing no separation nor lift after construction. COPYRIGHT: (C)2003,JPO
