PURPOSE: To prevent setting concrete from invading into the butt faces of heat- insulation panels and improve the workability of a joint material for the setting concrete without loss of insulation function of an insulating sheet 15.
CONSTITUTION: A waterproof layer 14 is formed on a slab concrete 11 and a heat-insulation panel 12 is laid thereon and further, a setting concrete 13 is placed thereon to make the ceiling wall, the floor, the side walls, etc., to have a heat-insulation structure. An insulation sheet 15 is fixed on the upper face of respective heat-insulation panels 12 and protruded from the side edge of the heat-insulation panel 12 to reach the adjacent heat-insulation panel 12 and fixed thereto. Concrete 13 does not reach the waterproof sheet 14 through the connected end face 12a owing to the protruded pieces 15a. Since the insulation sheet 15 is fixed on the heat-insulation panel 12, it is hardly shifted even when operators walk and marking for joints 16 does not warp.
