Conventionally, the general method for constructing mortar-painted walls in buildings is to first attach a lath base plate, then attach waterproof paper such as asphalt roofing paper on top of that, and then attach a wire mesh such as metal lath on top of that. This method was followed by applying mortar coating, but this method required labor and time as it was a wet field work, and was not fully satisfactory in terms of waterproofness and cracking on the mortar coated surface. It was not possible to assume that it was. In addition, in recent years, two-by-four construction methods and other panel construction methods have been adopted, but even in these cases, there remains the problem that wet site work must be carried out if mortar coating is required. has been done.

The flexible porous sheet 2 attached to or embedded in the surface of the inorganic layer 1 includes metallic flexible porous sheets such as metal lath and wire lath, as well as cheesecloth or nonwoven fabric made of synthetic fibers, natural fibers, inorganic fibers, etc. is used. When attaching or embedding such flexible porous sheet 2 on the surface of the inorganic layer, it may be chemically attached using an adhesive, or it may be partially embedded before the inorganic layer hardens. , or may be physically attached using an auxiliary part such as a staple.

The flexible waterproof sheet 3 disposed on the back side of the inorganic layer is made of a thin and flexible material such as impregnated paper or impregnated nonwoven fabric, vinyl chloride, or rubber treated with a waterproofing agent or water repellent such as asphalt or asphalt felt. A sheet-like material having properties is adhered to the back surface of the inorganic layer by adhesive or self-fusion. In addition, if a material with a high elongation rate is selected for the flexible waterproof sheet 3, the degree of freedom in construction on curved surfaces will be greater, and even when construction is performed on areas such as inside corners, the inorganic layer can be bent without cutting. It has the advantage of being able to

Furthermore, in order to reinforce the joints between adjacent base materials, a flexible porous sheet or flexible waterproof sheet may be attached slightly protruding from both ends of the inorganic layer, or a flexible porous sheet or flexible waterproof sheet with a wide area may be attached. It is also possible to attach a flexible waterproof sheet and use it by inserting protruding sheet-like objects or flexible waterproof sheets that are adjacent and facing each other into the joint portions during construction.

Because the present invention has the above-mentioned structure, it is not only labor-saving as a construction base material compared to the conventional construction material, but also has an inorganic layer containing foamed particles and a flexible material attached to the surface. The flexible porous sheet provides good adhesion with the top coat mortar, and the effect of the flexible porous sheet attached to or embedded in the inorganic layer surface greatly reduces the occurrence of cracks after finishing the top coat mortar. Furthermore, by fixing the flexible porous sheet to the structure with staples or nails, a strong structure can be constructed.
