HEATABLE FLOOR STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a heatable floor structure which 1) prevents the surface of a floor from getting too high above the ground work surface of the floor of a building, 2) eliminates an excessive increase in the material cost for the floor and 3) significantly simplifies construction work as compared with the conventional floor. SOLUTION: A subfloor plate is mounted on an underfloor ground surface being supported by a support leg 12 and joist pieces 15 are arranged on the top surface of the subfloor plate at a fixed interval. A floor heating panel 16 which has a flexible tube 19 for a heat medium imbedded into a groove cut into the top surface thereof is arranged between the joist pieces 15 adjacent to each other and a surface cover layer 17 is arranged on the top surfaces of the floor heating panel 16 and the joist pieces 15.
