PROBLEM TO BE SOLVED: To provide a construction method of a hot water mat corresponding to such a case that a construction floor area is wide.SOLUTION: A mat substrate 2 is constituted with an intermediate panel 3 of a quadrangle in plain view, upper and lower U-turn panels 4, 5 arranged along up and down edges of the intermediate panel 3 and a conduit pipe panel 6 arranged along the upper edge of the upper U-turn panel 4, the mat substrate 2 is arranged on a construction site, the pipeline of a hot water pipe 24 enters into a pipeline groove 7 formed on the intermediate panel 3 via the upper U-turn panel 4 from the conduit pipe panel 6, subsequently, is inverted via a U-turn pipeline groove formed on the lower U-turn panel 5, is inverted to the left side via the U-turn pipeline groove formed on the upper U-turn panel 4, reaches the intermediate panel 3, the piping is performed to the left edge of the mat substrate 2 while the piping is repeated, the pipeline is inverted to the right side and, the return piping is performed to each panel in the same manner as described above to perform the piping of one circuit on the mat substrate 2. |
