2 is the tension.

However, in all of these, the floor @ tassel panel is installed by placing it on the top surface of the joist 24, and the pipe 23 is located above the joist 24, so that the floor surface is There are problems with the raised state, such as differences in floor height between rooms with underfloor heating and rooms without underfloor heating, and both of these underfloor heating panels There was also the problem that the structure became complicated and the cost increased.

[Object of the Invention] The present invention has been made in view of the above points, and there is no fear that the floor surface will be raised too much.
It is an object of the present invention to provide a floor heating panel that can be easily formed into a 3-dimensional structure.

[Disclosure of the Invention J The floor panel according to the present invention is formed by applying a heat insulating material 2 to the lower surface of a metal plate 1, and is placed and fixed on joists 3 at both side ends of the metal plate 1. A flange piece 4 extends outward, and at a position closer to the inside than the flange piece 4, the metal plate 1 is bent upward to fit and attach a pipe 5 for passing a heating medium. It is characterized by being provided with an open storage groove 6,
The above object is achieved by allowing the pipe 5 to be installed in the storage groove 6 without protruding significantly above the joist 3, and by allowing the metal plate 1 and the heat insulating material 2 to form a floor panel. The present invention will now be described in detail with reference to Examples.

At both ends of the metal plate 1, there are parallel storage grooves 6.6 whose upper surfaces are open by convexly bending the metal plate 1 downward.
It is formed as shown in FIG. 13(a), and flange pieces 4, 4 extend outward from both ends of the metal plate 1 on the outside of the storage groove 6. The flange piece 4 has seven holes 7 for passing nails, screws, etc. The storage groove 6 is formed to have an arcuate cross-section, and the metal plate 1 is formed so that, except for the storage groove 6, the upper surface of the portion between the 7 flange pieces 4 and the 1 storage groove 6.6 is plane-to-plane. It's Nishide. This metal plate 1
By pasting a heat insulating material 2 such as glass wool or polyurethane foam on the lower surface, 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. Also, the storage groove 6 of the metal plate 1
The length dimension in the direction parallel to the metal plate 1 is set to about 50 cm, and the width dimension of the metal plate 1 is set to such a size that the flange pieces 4 are respectively mounted on the upper surfaces of the adjacent joists 3.

Therefore, in the construction, first, as shown in FIG. 4(a), joists 3 are attached on top of the drawers 15 at a pitch that matches the width dimension of the metal plate 1. The panel A of the floor @ formed as described above is arranged between the adjacent joists 3 and 3 as shown in the f:tfJ1 diagram, and the insulation material 2 and the storage groove 6 are dropped between the joists 3 and 3. At the same time, place the flange pieces 4 on both sides of the metal plate 1 on the upper surface of each adjacent joist 3.3, and fix them to the joists 3 by driving nails, screws, etc. into the joists 3 through the holes 7 of the flange pieces 4. It is something. In this way, as shown in Fig. 4(b), a plurality of floor heating panels A are lined up along the joists 3, and a plurality of floor heating panels Δ are placed in the same way between the adjacent joists 3 and 3. Arrange. 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 panel A, but the pipe 5 is a flexible plastic pipe. It is better to use Of course, this is not the intention to preclude the use of metal pipes. The piping of the pipe 5 can be done by making one pipe 5 into a meandering shape and fitting it into the storage groove 6 provided in the metal plate 1 of each floor heating panel A. By allowing the heat medium to circulate through the single pipe 5 in this manner, there is no need for a joint that is required when connecting a plurality of 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. 2 and 4(e). That is, between each joist 3, an outgoing portion 5II 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 are arranged respectively, and the highest temperature The pipe 5 in the outgoing section 5a through which the heating medium passes and the pipe 5 in the incoming section 5b through which the low-temperature heating medium passes are installed on the same floor @ panel A, and the I8+, which has the next highest temperature, The arrangement of the pipes 5 is set such that the pipe 5 in the section through which the heating medium passes and the pipe 5 in the return section 5b through which the low-temperature heating medium with the second lowest temperature passes are attached to the same floor heating panel A. It is something that will be done. By arranging the pipes 5 in this manner, it is possible to equalize the heat reception 1 of the heat medium inside the pipes 5 on each floor + 111 panel A. 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 way, the bending stress of the pipe 5 can be reduced, and the thermal expansion of the pipe 5 that is caused by the passage of a heat medium of nearly 100° C. can be absorbed. Become.

The pipe 5 is formed into a meandering shape by bending the joist 3 at four positions, but at the bent part, the pipe 5 is concave downward except for the flange piece 4, as shown in FIG. 3(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 on which four bent parts 13 are formed. Make it. Of course, a metal plate having a detour groove into which the detour part 12 is fitted may be used.Also, for the bent portion of the pipe 5, a notch 14 is provided in advance at the end of the joist 3, and the notch 14 is Let it pass. The cutout 14 only needs to be provided at the end of the joist 3, and the number of man-hours required for the cutout 14 can be minimized. Further, the bent portion of the pipe 5 may be fixed to the joist 3 within the notch 14.

After the pipes 5 are arranged 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. 4(d). Here, a gap is formed between the tips of the flange pieces 4° 4 of the adjacent floor heating panels A and B on the top surface of each joist 3, and the top surface of the joist 3 is exposed from this gap. By driving nails or screws from the finished flooring material 16 into the joists 3 at this exposed part, the finished flooring material 16 is removed.
It is used to fix the In this way, when the finished flooring 16 is stretched over the floor heating panel A, the entire upper surface of the metal plate 1 except for the storage groove 6 is covered with the finished flooring 16.
6, the heat generated from the pipe 5 can be uniformly transmitted to the entire surface of the finished flooring 16 through the metal plate 1.

[Effect of the invention 1 As described above, the floor +I according to the present invention! The tuft panel is formed by applying a heat insulating material to the lower surface of the metal plate, and has flange pieces extending outward from both side ends of the metal M@ to be placed and fixed on the joists. At a position closer to the inside, a pipe for passing the heating medium is inserted into the metal plate by bending it downward and ＼. ) is provided with a storage groove that opens upwards for attachment, so the pipe for passing the heating medium can be placed between the joists, and the pipe will not protrude further upwards than the joists. It is possible to hold the pipe without worrying that the floor will be raised, and it is 2/2 of the metal plate and the insulation material! The floor 1115j panel can be formed with this configuration, and the inscription can be simplified and produced at low cost.
