To provide a floor heating device in which heat transfer from the metal plate to the finished floor material is improved by holding the finished floor material in close contact with the metal plate.

[Disclosure of the Invention J In the floor heating device of the present invention, a floor heating panel A is formed by placing a heat insulating material 2 on the lower surface of a metal plate 1, and 11 The installed flange piece 4 is placed and fixed on the joist 3, and a heating medium is placed in the upper opening storage groove 6 formed in the metal plate 1 by downward bending at a position closer to the inside than the flange piece 4. It is characterized in that a pipe 5 for passing through is fitted and attached, and a finished flooring material 16 is applied to the surface of the metal plate 1 via a flooring material adhesion holding part 17, and as described above, it is possible to This solves the drawbacks of the conventional example. In other words, the floor heating panel A is formed by placing the heat insulating material 2 on the lower surface of the metal plate 1, and the flange pieces 4 extending outward from both side edges of the metal plate 1 of the floor heating panel A are placed on the joists 3. An upper-opening storage groove 6 is formed by bending the metal plate 1 downward at a position closer to the inside than the flange piece 4.
Since the pipe 5 for passing the heating medium is fitted and attached to the housing, the pipe 5 can be installed in the storage groove 6 without protruding significantly above the joist 3, and the metal plate 1 and the heat insulating material 2 allows the floor heating panel A to be formed with a simple structure, and furthermore, the metal plate 1
Since the finished flooring material 16 is applied to the surface of the metal plate 1 through the floor material adhesion holding part, the finished flooring material 16 can be attached to the surface of the metal plate 1 in close contact with the surface of the metal plate 1. .

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. At both ends, flange pieces 4, 4 extend outward. 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 the metal plate 1 includes the flange piece 4 and the storage groove 6, except for 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 cm, and the width dimension of the metal plate 1 is such that the flange pieces 4 are adjacent to each other with a radius i''.
It is set to the dimensions of the culms that are installed centrally on the top surface of No.3.

For construction, first, as shown in FIG. 4(a), joists 3 are attached to the main drawer 15 at a pitch that matches the width dimension of the metal plate 1. 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 storage groove 6 are placed between the joists 3 and 3, and the flange 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 a nail or screw into the joist 3 through the hole 7. 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 A are also lined up between adjacent joists 3 in the same way. Between the floor heating panels A arranged along the joists 3, the storage m6 is continuous at the end thereof.

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. As the pipe 5, a flexible plastic pipe is used. It is good to use.

Of course, this does not mean to preclude the use of metal pipes. The pipe 5 can be installed by fitting the pipe 5 into a storage groove 6 provided in the metal plate 1 of each floor heating panel A while making the pipe 5 into a meandering shape.

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 of the pipe 5 is routed as shown in FIGS. 3 and 4(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 5 of the pipe 5 to which the heating medium is returned.
In addition, the pipes 5 in the outgoing portion 5a through which the high temperature heat medium with the highest temperature passes and the pipes 5 in the return path portion 5b through which the heat medium with the lowest temperature passes are the same floor heating panel. In addition to being able to be attached to A,
The pipe 5 of the outgoing section 5a through which the high-temperature heat medium with the next highest temperature passes and the pipe 5 of the return section 5b through which the low-temperature heat medium with the second lowest temperature passes are attached to the same floor heating panel A. The arrangement of the pipes 5 is set accordingly. By arranging the pipes 5 in this manner, the amount of heat received from the heating medium in the pipes 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 are four parts 1 that are concavely bent downward, excluding the flange 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 on which a metal plate 3 is formed, and a detour part 12 of a pipe 5 is housed in this recess 13. Of course, a metal plate having a detour groove into which the detour portion 12 is fitted may be used. Also pipe 5
For the bent part, a notch 14 is made in advance at the end of the joist 3, and this notch! 14.

After installing the pipe 5 in this way, as shown in Fig. 4 (
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. At this time, the finished flooring material 16 is stretched between the surface of the metal plate 1 and the finished flooring material 16 through the flooring material adhesion holding part 17 so that the finished flooring material 16 is in close contact with the surface of the metal plate 1 and the finished flooring material 16. The floor material adhesion holding portion 17 is made of, for example, a double-sided adhesive tape, adhesive, paint, putty, caulking material, or the like.

It is preferable that these materials have high heat conductivity.

Further, the close contact holding portion 17 may be a magnetic sheet or a planar 7-asner. In the case of a magnetic sheet, a magnetic sheet is attached to the metal plate 1 and an iron plate is attached to the back side of the finished flooring material 16, or an iron plate is attached to the metal plate 1 and a magnetic sheet is attached to the finished flooring material 16. In the case of surface fasteners, metal plate 1 and finishing floor material 1
6 are provided with planar fasteners that engage with each other. In addition, in order to make the finished flooring 16 adhere to the metal plate 1, the surface of the metal plate 1 may be sharpened and cut into the back side of the finished flooring 16, or the back side of the finished flooring 16 may be made smooth. good. Furthermore, in order to ensure that the finished flooring 16 is held securely, the finished flooring 16 may be fixed as follows. In other words, adjacent floor heating panels A and B on the upper surface of each joist 3 and 3
A gap is formed between the tips of the flange pieces 4.4, and the upper surface of the joist 3 is exposed through this gap, and nails or screws can be attached to the joist 3 from the finished flooring material 16 at this exposed part. The finished flooring material 16 is fixed by driving. When the finished flooring 16 is stretched over the floor heating panel A in this way, the metal plate 1 is placed in the storage groove 6.
The entire upper surface of the pipe 5 is in close contact with the lower surface of the finished flooring material 16, except for the metal plate 1, so that the heat generated from the pipe 5 can be uniformly transmitted to the entire surface of the finished flooring material 16 by the metal plate 1.

At this time, flooring material v! Since the finished flooring material 16 is held in close contact with the attachment holding section 17, the finished flooring material 1 can be removed from the metal plate 1.
6 is further improved.

[Effects of the Invention] As described above, in the present invention, a floor heating panel is formed by applying a heat insulating material to the lower surface of a metal plate, so it is possible to prevent heat radiation loss downward from the metal plate, which transmits heat to the floor. At the same time, it is possible to integrate the metal plate and the heat insulating material to increase rigidity and prevent downward deformation. It is placed and fixed on the joists, and a pipe for passing the heating medium is fitted into the storage groove of the upper opening formed by the downward bending of the metal plate at a position inward from the flange piece. The pipes that carry the heat medium can be placed between the joists, so the pipes do not protrude above the joists, and the pipes can be held without the risk of raising the floor. Moreover, it is possible to form a floor heating panel with a simple two-layer structure of a metal plate and a heat insulating material, and it can be produced at a low cost.In addition, a heat insulating material is inserted between the joists and a flange piece is formed. It is easy to install as it can be installed simply by placing it on the joist and fixing it, and the finish flooring is applied to the surface of the metal plate via the flooring adhesion holding part, so the metal plate can be easily installed. The finished flooring material can be attached to the surface of the metal plate in close contact with the surface of the metal plate, and heat transfer from the metal plate to the finished flooring material can be improved to provide effective heating.
