The present invention will be explained in detail below with reference to Examples.

Parallel storage grooves 6.6 are formed at both ends of the metal plate 1 by convexly bending the metal plate 1 downward, and the upper surfaces of the metal plate 1 are open. Seven run pieces 4, 4 extend outward from both ends. The 7-run piece 4 is provided with holes 7 for passing fixing objects such as nails and screws.

The storage groove 6 is formed to have an arcuate cross section, and the metal plate 1 has seven run pieces 4 and the storage groove 6, excluding the storage groove 6.
The upper surface of the part between 6 and 6 is made to be plane-to-plane. By pasting a heat insulating material 2 such as glass wool or polyurethane foam on the lower surface of this metal plate 1, a floor heating panel A is formed to which a pipe 5 for passing a heat medium such as hot water is attached. The width of the heat insulating material 2 is set to be inserted between the joists 3 of a house. Further, the length dimension in the parallel direction of the storage groove 6 of the metal plate 1 is set to about 50 cw, and the width dimension of the metal plate 1 is set to 7.
The dimensions are set so that they can be placed on the top surface of each. Close contact portions 17 are provided on the sides of the heat insulating material 2 below the 72-inch pieces 4 on both sides.

In the embodiment shown in FIG. 2, this tight elastic contact portion 17 is formed by making the width of the heat insulating material 2 slightly larger than the interval between the joists 3 and 3, and by providing a free groove 18 between it and the run piece 4. By simply cutting the side end portions according to the width dimension between the joists 3, 3, the side end surfaces can be brought into close contact with the joists 3°3.

In the case of the embodiment shown in Fig. 3 In the embodiment shown in Fig. 2,
A close contact i17 is formed by providing a plurality of cuts WR19 on the lower surface, and the cut grooves 19 can be used to more easily cut the joists WR19 so that they can be brought into close contact with the side end surfaces of the joists 3, 3. In the case of the embodiment shown in FIG. 4, a soft part 20 made of a collapsible material such as a soft foam or glass wool is arranged below the 7-run piece 4, and the heat insulating material 20 is placed with the soft part 20 separated from the 7-run piece 4. A tight elastic contact portion 17 is formed by providing the elastic portion 17 integrally with the joists 3, so that the soft portion 20 can be crushed and brought into close contact with the joists 3, 3 without any gaps.

In the embodiment shown in FIG. 5, the side end surface of the heat insulating material 2 located below the 7-run piece 4 is made into an inclined surface 21 that goes inward toward the bottom to form a tight elastic contact portion 17, and between the joists 3 and 3. It is designed so that it can be easily pushed in and tightly attached to the 3°3 joists.

In the embodiment shown in FIG. 6, the side end surfaces are formed into inclined arcuate surfaces 22 to form a close contact portion 17. In the embodiment shown in FIG. 7, an inclined surface 23 opposite to that shown in FIG.
7 is formed.

In the construction, first, the joists 3 are attached to the main drawer 15 at a pitch that matches the width dimension of the metal plate 1, as shown in FIG. 9(,). The floor heating panel A configured as described above is constructed of adjacent joists 3 and 3 as shown in Figure 1.
The heat insulating material 2 and the storage groove 6 are placed between the joists 3 and 3, and the 7 run pieces 4 on both sides of the metal plate 1 are placed on the upper surface of each adjacent joist 3. It is fixed to the joist 3 by driving nails or screws into the joist 3 through the holes 7 of 4. At this time, the lower part of the 7th run piece 4 made close contact! 1s17 is in close contact with the side end surfaces of the joists 3, 3 without any gaps.

In this way, a plurality of floor heating panels A are lined up along the joists 3 as shown in FIG. Between the floor heating panels A arranged along the joists 3, the storage grooves 6 are continuous at their ends.

Next, a pipe 5 for passing the heat medium is installed to the floor heating panel A installed in this way, and the pipe 5 is held by the floor heating panel A. A flexible plastic pipe is used as the piper. is good.

Of course, use a metal vibrator = J-1. - To attach the pipe of the vibrator 5, one pipe 5 is made into a meandering shape and inserted into the storage groove 6 provided in the metal plate 1 of each floor heating panel A. This can be done by

By making it possible to circulate the heat medium through a single pipe 5 in this way, there is no need for a joint as is required when connecting multiple pipes, and the risk of liquid leakage from the joint can be eliminated. . Further, when the pipe 5 is fitted into the storage groove 6, the upper surface of the metal plate 1 and the upper end of the pipe 5 are flush with each other.

Here, the piping 5 is routed as shown in FIGS. 8 and 9(e). That is, each joist 3,
3, an outgoing portion 5a of the pipe 5 to which a heating medium such as hot water is supplied, and an incoming portion 5b of the pipe 5 to which the heating medium is returned.
In addition, the pipes 5 in the outgoing section 5a through which the high-temperature heat medium with the highest temperature and temperature passes and the pipes 5 in the return section 5b through which the lowest temperature heat medium passes are the same floor heating panel. A, and the pipe 5 of the outgoing portion 5a through which the high temperature heat medium with the next highest temperature passes and the return path portion 5 through which the low temperature heat medium with the second lowest temperature passes.
The arrangement of the pipes 5 is set so that the pipes 5 and 5 of b are attached to the same floor heating panel A. By arranging the pipes 5 in this manner, the amount of heat received from the heating medium in the vibrator 5 in each floor heating panel A can be equalized. Further, in the portion where the pipe 5 is bent, it is preferable to form a detour portion 12 in order to increase the radius of curvature of the bend. By forming the detour portion 12 in this manner, the bending stress of the pipe 5 can be reduced, and the thermal expansion of the pipe 5 that occurs due to the passage of a heat medium of nearly 100° C. can be absorbed.

The pipe 5 is formed into a meandering shape by bending it at the end of the joist 3. At the bending part of the pipe 5, there is a concave part 1 which is bent downward except for the run piece 4.
A floor heating panel B is used, which is formed by pasting a heat insulating material 2 on the lower surface of a metal plate 1 formed with a metal plate 3, and a detour part 12 of a pipe 5 is housed in the four parts 13. Of course, a metal plate having a detour groove into which the detour portion 12 is fitted may be used.
A notch 14 is provided in advance at the end of the joist 3 so that the bent portion passes through this notch 14.

After installing pipe 5 in this way, see Figure $9 (
Finished flooring 16 is placed on the floor heating panels A and B as shown in d).
It is finished as a floor by pasting it. Here, the floor heating panels A adjacent to each other on the upper surface of each joist 3, 3
A gap is formed between the tips of the 7 run pieces 4 and 4 of B, and the upper surface of the joist 3 is exposed through this gap, and nails or screws are inserted from the finished flooring 16 at this exposed part. The finished flooring material 16 is fixed by driving it into the joists 3. When the finished flooring 16 is stretched over the floor heating panel A in this way, the entire upper surface of the metal plate 1 except for the storage groove 6 comes into close contact with the lower surface of the finished flooring 16, and the pipes 5 The heat generated by the metal plate 1 can be uniformly transmitted to the entire surface of the finished flooring 16.

[Effects of the Invention] As described above, the present invention is formed by applying a heat insulating material to the lower surface of the metal plate, so it is possible to prevent heat radiation loss downward from the metal plate that transmits heat to the floor, and By integrating the board and the heat insulating material, it is possible to increase the rigidity and prevent downward deformation, as well as to prevent the metal board from deforming downward.At both side edges of the metal board, there are 7 run pieces placed and fixed on the joists that extend outward. In addition to being extended, the metal plate is bent downward at a position closer to the inside of the 7-run piece to provide a storage groove that opens upward for fitting and attaching the pipe for passing the heating medium. The pipe that carries the heat medium can be placed between the joists, so the pipe does not protrude far above the joists.
It is possible to hold pipes without the risk of raising the floor, and moreover, it is possible to hold the pipes without worrying that the floor will be raised.
A floor heating panel can be formed with a simple configuration of 1 and can be produced at a low cost.In addition, by simply inserting insulation material between the joists and placing 7 runno pieces on the joists and fixing them. It can be given as a gift and the construction can be carried out by a team, and since the side of the insulation material located below the 7-run piece has a close-fitting external part that fits tightly to the joist without any gaps, the close-fitting external part can be It can be tightly attached to the joists without any gaps to improve heat insulation and reliably prevent heat radiation downward.
