PROBLEM TO BE SOLVED: To remove a panel only one sheet from the floor, and stick heat accumulating material to the rear of the floor panel, by fixing frames, where heat generators, heat accumulating material, etc., are stacked, one piece, two pieces, or more to the rear of one sheet of floor panel. SOLUTION: The floor is made by arranging a plurality of sheets side by side as for floor panels, and executing flooring 4 thereon, and tow pieces each of frames 5 are fixed apart to the rear of each floor 2. Inside each frame 5, heat insulating material 6, first heat accumulating material 7, a heater 8, and a second heat accumulating material 7 are stacked in order from on the bottom plate. Hereby, the floor panel can be held up, removing only one sheet from the floor, so the work at maintenance of a wiring cable becomes easy, and also since the heater and the heat accumulating material can be stacked practically without space to the rear of the floor panel, such a fear as to drop the efficiency in heating vanishes. |
