At both ends of the metal plate 1, parallel storage grooves 66 are formed by convexly bending the metal plate 1 downward and having open upper surfaces, as shown in FIG.
It is formed as shown in FIG. 1) and FIG. 5(b), and on the outside of this storage groove 6, flange pieces 4.4 extend to the outside no.J at both ends of the metal @1. The flange piece 4 is provided with a hole 7 for passing a fixed object such as a nail or screw. The storage groove 6 is formed to have an arcuate cross section, and is made of gold! A plate 1 has 1. m, flange piece 4
The storage grooves 6 and 6 are arranged so that the upper surface of the dark part becomes a surface-to-surface surface.

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 w1 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 into three joists of the house. In addition, the width dimension of the metal plate 1 in the direction parallel to the storage groove 6 is set to about 50 cm, and the width dimension of the metal X plate 1 is such that the flange pieces 4 are placed on the upper surface of the joist 3 where they meet. The dimensions are set to .

Therefore, the floor I11 panel A formed as described above
When installing a floor heating 175 device using
First, as shown in Figure 3 (&), place the meeting [
A plurality of joists 3 are installed in parallel at a pitch that matches the width dimension of 1. At this time, notches 14 are cut out and provided on the upper surface of each of the joists 3 except for the end portions at one Q section alternately.

The floor heating panel A formed as described above is 11
As shown in the figure, the insulation material 2 and the storage groove 6 are placed between the adjacent joists 3.3, and the flange pieces 4 on both sides of the metal plate 1 are placed between the adjacent joists 3.3. It is placed on the upper surface of the joist 3 and fixed to the joist 3 by driving nails, screws, etc. into the joist 3 through the hole 7 of the flange piece 4. In this way, as shown in Fig. 3(b), a plurality of floor heating panels A are lined up along the joists 3, and a plurality of floor heating panels A are similarly placed between the adjacent joists 3 and 3. Line them up. Between the floor heating panels Δ stretched along the joists 3, the ends of the metal plates 1 are butted against each other so that the storage grooves 6 are continuous at the ends.

Next, the pipe 5 for passing the heat medium is connected to the floor heating panel 8 attached in this way, and the pipe 5 is held by the floor heating panel A.
It is best to use a plastic vibrator with T flexibility. Of course, this does not mean to preclude the use of metal vibrators.In the piping of the nine pipes 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. It can be done. By circulating the heat medium through the single pipe 5 in this way, there is no need for joints as in the case of connecting existing pipes, and there is no risk of liquid leakage from the joint. ``I can do it.

Here, the pipe 5 is bent in a meandering manner so that it can be laid along the route shown in FIGS. 2 and 3(C). In other words, the pipe 5 is arranged so that the end where the heat medium such as hot water is introduced and the end where the heat medium is sent out are located on the same floor heating panel A, and It is formed by the outward path 5a to which the heat medium is supplied and the return path 5b to which the heat medium is returned.
b are bent in a meandering manner so as to be attached to one storage groove 6 and the other storage groove wt6 of the pair of storage grooves 6, 6 of the floor heating panel A, respectively.

Furthermore, the pipe 5 of the outgoing route 5a through which the high temperature heat medium with the highest temperature passes and the pipe 5 of the return route 5b where the low temperature heat medium with the lowest temperature passes are connected to the floor heating panel A between the same joists 3. At the same time, the pipe 5 of the outgoing route 5a, which is the part through which the second highest temperature high-temperature heating medium passes,
and the return path 5 where the low-temperature heating medium with the second lowest temperature passes through.
The pipe 5 of b is attached to the floor heating panel A between the same joists 3 of the pond, and the pipe 5 of the outgoing route 5a and the part where the high temperature heat medium passes in the same order and the low heat medium pass in the same way. Part return path 5 The pipe 5 of b is the same joist 3
Pipe 5 so that it can be attached to the floor heating panel 8 between
This is a meandering bend. By arranging the pipe 5 in such a meandering shape, between the joists 3 located at the ends, heat is received from the heat medium having the highest temperature and the lowest temperature by the outward path 5a and return path 5b of the pipe 5. , between the next joists 3, heat is received from the heat medium having the second highest temperature and the second lowest temperature by the outgoing path 5a and the incoming path 5b of the pipe 5, and in the same manner, heat is received from the heat medium of the second highest temperature and the second lowest temperature.
11j, the outgoing path 5a and the incoming path 5IJ and t of the pipe 5
As a result, heat is received from the high-temperature heat medium and the low-temperature heat medium in the same order. Therefore, it is possible to equalize the amount of heat received from the heating medium of the pipe 5 in each floor heating panel A, and it is possible to equalize the distribution of temperature in the room I11 in the floor heating system. .

In addition, when the pipe 5 is bent and meandered as described above, the radius of curvature of the bend is small because the distance between the outward paths 5a and the backward paths 5b of adjacent pipes 5 via the joist 3 is narrow. In this case, there arises a disadvantage that the bending stress acts largely on the bent portion.

Therefore, in this bent portion, it is preferable to form a detour portion 12 in order to increase the radius of curvature of the bend. By forming the detour part 12 in this way and forming a large bending radius of curvature, it is possible to reduce the bending stress of the pipe 5, and also to
This means that the detour portion 12 can absorb the large thermal expansion of the pipe 5 caused by the passage of the nearby heating medium.

The pipe 5 is formed into a meandering shape by bending the end portion 1iff of the joist 3 (near the wall of the room), but at the bending portion of the pipe 5, the flange piece 4 is inserted as shown in FIG. 4(b). 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, which has four parts 13 that are concavely bent in the opposite direction. The portion 12 and the bent portion are stored. At this time, as shown in FIG. 5(a), an id protrusion 17 is provided in the recess 13 to guide the bending of the pipe 5, and the id protrusion 17 allows the pipe 5 to bend accurately. Alternatively, the bent portion of the pipe 5 to make it meander may be made to protrude from the floor panel B, and this bent portion may be formed in a notch 14 previously provided at the end of the joist 3. At the bent part where the notch 14 passes, the joist 3
Adjacent floor 1Iiy through! j In order to connect the pipes 5 between panels A and B as one unit, and to connect the pipes 5 between the adjacent floor Q panel A via the 0Mi thick 3, connect the joists every time each floor heating panel A is opened. Normally, a notch is provided in the joist 3 to allow the pipe 5 to pass through, but the notch 14 only needs to be provided at the end of the joist 3. The decrease in strength of the joists 3 due to this can be minimized, and the number of man-hours for forming the cutout portions 14 can be minimized. Note that the bent portion of the pipe 5 is formed by this notch 14.
It may be fixed to the joist 3 inside.

After the pipes 5 have been installed in this manner, a finished flooring material 16 is placed over the floor heating panels A and B to form a finished floor, as shown in FIG. 3(d). Here, a gap is formed between the tips of the flange pieces 4, 4 of adjacent floor heating panels A and B on the upper surface of each joist 3, and this gap C) exposes the upper surface of the joist 3. Then, the finished flooring 16 is fixed by driving nails or screws into the joists 3 at the exposed portions of the finished flooring 16. With the finished flooring 16 stretched over the floor heating panel A in this way,
The upper surface of the metal plate 1 is in close contact with the lower surface of the finished flooring material 16, and the heat generated from the pipe 5 is received by the metal plate 1, and the heat from the metal plate 1 is further transmitted to the finished flooring material 16, thereby providing floor heating. can be carried out.
