PROBLEM TO BE SOLVED: To reduce a labor for work at site and reduce noise at a working site by a method wherein a hot-water mat is laid on a floor and, thereafter, dummy members are laid on stepped parts between the hot-water mat and peripheral walls to eliminate the stepped parts. SOLUTION: A hot-water mat 1 is laid and dummy members 10 are laid on stepped parts generated at the periphery of the mat 1. The dummy member 10 is cut so as to meet the width and length of the stepped part 2. The dummy member can be cut simply by forming a shallow cutting harm on the surface of the ceiling plate with a cutter or the like and bending the dummy member. When a cutting groove is formed on the ceiling plate 11 previously, the dummy member can be cut simply without employing any tool by bending along the cutting groove. A hot-water pipeline 4 can be arranged in predetermined directions through penetrating holes formed on the leg plates of the dummy member 10. The dummy member 10 is constituted of a flat and smooth ceiling plate 11 and a lattice type leg plates 12 formed integrally with the lower surface of the ceiling plate 11 while they are molded integrally through injection molding method employing ABS resin, polyethylene or the like as the material thereof. |
