Document Type and Number:
Japanese Patent JPH11227081
Kind Code:
A
Abstract:
To provide an ideal fire resistant composite floor material having a low cost, a high strength, a light weight, excellent fire resistance and excellent processability by using a gypsum for the floor material.
In the fire resistant composite floor material 7 comprising a reinforcing layer 4 made of a thermosetting resin and an inorganic fiber and provided at least on one of a front side surface 71 and a rear side surface 72 of a porous inorganic core material 3, the material 3 is obtained by laminating and adhering a plurality of gypsum boards 31, 32. An overall thickness T of the material 3 is 9.5 to 30.0 mm. Its specific weight is preferably 0.9 to 1.5. And, the gypsum plate may be used instead of a gypsum board.
