TATAMI BED FOR BUILDING MATERIAL

PROBLEM TO BE SOLVED: To easily demolish and recycle a tatami bed while securing the flexibility of a tatami bed by sticking mutual tatami boards or the tatami boards and mutual polystylene foam boards to each other through an elastic adhesive partially arranged. SOLUTION: A plurality of tatami boards 1, 1 or tatami board 1 and polystyrene foam board, a protection member 3, and a rear face member 4 are laminated to form a taami bed A for a building material. In this case, the mutual tatami boards 1 or the tatami board 1 and polystylene foam board are stucked to each other through an elastic adhesive 6,... disposed to be distributed in a linear way or a dotted way. The part where the tatami board 1 comes into contact with the elastic adhesive 6 is reinforced by a reinforced resin part 8,... In this way, while the flexibility of the tatami bed A is secured and the manufacturing cost is reduced, the tatami bed A can be easily demolished and recycled.
