PROBLEM TO BE SOLVED: To couple a resin tube of a heat insulation tube directly to a heating floor by passing an end of the insulation tube to a soft resin coating tube to seal it with a sealing material, then embedding it in concrete, solidifying the concrete, and then cutting the coating tube to become in plane with a floor surface. SOLUTION: An end of a heat insulation tube 1 is passed through a coating tube 4, and its exit is sealed by sealing materials 5 such as adhesive tape, adhesive and the like. Then, the tube 4 is positioned so that a floor indication mark attached to its outside surface of the tube 4 is located just on a floor surface. A wire or reinforcing bar is passed fixedly through a connecting hole 9, and the tube 1 horizontally inserted from the exist is bent upward. The tube 1a of the end of the tube 1 is projected from an outlet 7. The tube 4 is embedded in concrete. The concrete is then solidified, and the tube 4 is cut by a cutter knife or the like so as to become in plane with the floor surface. Accordingly, its operation can be easily and accurately executed. |
