What is routed to the resin board 10 of small mats E, the other end is connected to the header 20.

  In addition, the piping route of the hot water piping 3 is not limited to this.

After each hot water pipe 3 is routed by the above piping route, a soaking sheet 7 is arranged so as to cover the top surfaces of the small mats A to H, and this soaking sheet 7 is bonded to the top surfaces of the small mats A to H. Affixed with an agent or the like. In this embodiment, the soaking sheet 7 covering the upper surfaces of the small mats A to D is continuous across the butted portions T _{1 to} T ₃ between the small mats A to D. The soaking sheet 7 covering the upper surfaces of the small mats E to H is also continuous across the butted portions T _{1 to} T ₃ between the small mats E to H. And soaking the sheet 7 covering the columns of the small mat to D, the soaking sheet 7 covering the columns of small mats E-H, it is divided along the butted portion T _4.

  In addition, by sticking the soaking sheet 7 continuously on the upper surfaces of the small mats A to D in this way, the resin boards 10 to 16 constituting the small mats A to D and the small joists 30 between them. Are connected together, and the small mats A to D are also connected so as not to be separated. Moreover, the resin boards 10-16 which comprise each small mat EH and each small joist 30 between these are connected by sticking the soaking | uniform-heating sheet 7 continuously on the upper surface of small mat EH. In addition, the small mats E to H are also connected so as not to be separated.

  As shown in FIG. 7, when the soaking sheet 7 is adhered, the side edge of the pipe connection space 10a and the pipe are formed in the vicinity of the pipe connection space 10a of the resin board 10 of the small mat E. The soaking sheet 7 is adhered to the upper surface of the resin board 10 between the groove 2 closest to the connection space 10a.

At this time, in order to prevent the soaking plate 6 disposed in the groove 2 closest to the pipe connection space 10a from being attached to the resin board 10, the pipe 2 protrudes from the groove 2 toward the pipe connection space 10a. The soaking sheet 7 is protruded from the flange portion 6 b of the soaking plate 6 toward the pipe connecting space 10 a side and adhered to the upper surface of the resin board 10. In this embodiment, since between the return pipe connection port 23 and the first return side the hot water pipe connection port 25 of the first side surface 21c of the header 20 are spaced _{S 3} of 20 to 100 mm, the pipe A sufficient width of the resin board 10 between the connection space 10a and the groove 2 adjacent to the space 10a can be secured, whereby the heat equalizing plate 6 disposed in the groove 2 is attached to the resin board 10. The soaking sheet 7 can be attached to the resin board 10 so as not to be attached.

In this embodiment, the rows of the substrates A to D are valley-folded along the butted portions T _{1 to} T _3, and the rows of the substrates E to H are also valley-folded along the respective T _{1 to} T _3. , substrate a, by mountain fold along the butted portion T ₄ between E, it is possible to fold the floor heating mat 1.

  In constructing a heating floor using the floor heating mat 1, the floor heating mat 1 is spread and spread on the floor floor of the room. Then, the body portion 21 of the header 20 is fastened to the floor base with a fastening tool 29 such as a screw through the fastening tool insertion portion 28. Next, the outward pipe 40 and the return pipe 41 of the external hot water circulation path drawn under the floor are pulled out to the pipe connection space 10a, and the outgoing pipe 40 is connected to the outgoing pipe connection port 22 of the header 20, respectively. 41 is connected to the return pipe connection port 23. Then, a flooring material (not shown) is constructed on the floor heating mat 1 to construct a heating floor.

  The effects of the header 20 and the floor heating mat 1 are as follows.

  In this header 20, the outgoing pipe connection port 22, the return pipe connection port 23, and the hot water pipe connection ports 24, 25 are respectively the first side surface 21 c of the body portion 21 and the second side facing this. It protrudes from the side surface 21e. Therefore, the space for connecting the pipes 40, 41, 3 to these connection ports 22, 23, 24, 25 is only on the first side surface 21c side and the second side surface 21e side of the body portion 21. It's enough.

  Therefore, in the floor heating mat 1 provided with this header 20, the space required for installation of the header 20 can be reduced as compared with the case of installing a header with pipe connection ports protruding in three directions from the body portion. . Further, the header 20 has a protruding direction of the outgoing pipe connection port 22 and the return pipe connection port 23 and the hot water pipe connection ports 24 and 25 substantially parallel to the extending direction of the groove 2 of the resin board 10. Therefore, handling of each hot water pipe 3 when connecting each hot water pipe 3 to the header 20 is easy. The header 20 is provided with projecting pipe connection ports 22 to 25 only in a direction substantially parallel to the extending direction of the groove 2, and a pipe connection is formed in a direction orthogonal to this, that is, in the lateral direction of the resin board 10. Since no space is required, the header 20 can be easily installed on the resin board 10 having a relatively small width.

  In this embodiment, the outgoing hot water pipe connection port 24 and the return hot water pipe connection port 25 are alternately projected from the body portion 21 of the header 20 in the same direction. Therefore, the hot water flow direction is opposite between the adjacent hot water pipes 3 and 3. The hot water flowing through the hot water pipe 3 has the highest water temperature at the outgoing side hot water pipe connection port 24, and the water temperature becomes lower as it approaches the return side hot water pipe connection port 25. Therefore, the amount of heat transferred from the hot water pipes 3 and 3 to the soaking sheet 7 through the soaking plate 6 is equalized.

  In general, the header 20 is arranged so that the outgoing pipe connection port 22 and the return pipe connection port 23 are respectively directed to one end side in the long side direction of the resin board 10 (that is, the outer side side in this embodiment). In the header 20 of the present invention, the hot water pipe connection ports 24 and 25 project from the body portion 21 in substantially the same direction as the forward pipe connection port 22 and the return pipe connection port 23 and in the opposite direction. The hot water pipes 3 connected to the hot water pipe connection ports 24 and 25 oriented in substantially the same direction as the forward pipe connection port 22 and the return pipe connection port 23 extend to the outer side of the resin board 10 without difficulty. Can be made. Thereby, each hot water piping 3 can be drawn around the connection part 31 formed along the outer side of the resin board 10.

  In addition, in the header of the type in which each connection port extends in three directions from the body part, this header is arranged so that the outgoing pipe connection port and the return pipe connection port are respectively directed to one end side in the long side direction of the resin board. When arranged, each hot water pipe connection port is oriented in the short side direction of the resin board. Therefore, it is difficult to extend each hot water pipe connected to each hot water pipe connection port in the long side direction of the resin board. For this reason, in order to route hot water piping from the resin board where this header is arranged to the next resin board without difficulty, the length of the small joists is shortened and the resin boards are placed in the middle of the long side of the resin board. It is necessary to provide a connecting part for connecting the two.
