An embodiment of the method of the present invention will be described in detail below with reference to the drawings.

First, the component structure used in the method of the present invention will be described.

The floor constituent material 5 is constructed by completely adhering the heat dissipating plate 4 and the heat dissipating plate 4 with adhesive, wood screws, etc. so that no air layer is formed between them. Reference numeral 3 designates a hot water circulation pipe in which a high temperature section and a low temperature section are housed in a meandering manner within the groove 2, and is previously shaped into a meandering shape.

It is preferable that the thickness of the core material 1 directly above the hot water circulation pipe 3 is made as thin as possible, but considering the concentrated load from the top, it should be made to an appropriate thickness depending on the material, for example, the thickness of the thinnest part. Let there be two cranes.

The grooves 2 provided on the lower surface of the core material 1 are shown in FIGS. 2(a) to (e).
As shown in the figure, the grooves can be shaped like a tunnel, a triangle, a chevron, a square, a protrusion, etc., and the width and depth H of the groove 2 are adjusted according to the outer diameter of the hot water circulation pipe 3. .

In the case of the tunnel-shaped groove shown in Fig. 2(a), the radius R of the upper part of the groove is
It is preferable that the surface is equal to or slightly larger than the radius of the hot water circulation pipe 3 to prevent gaps.

In addition, in the case of a chevron-shaped groove as shown in Fig. 2 (C1), that is, the second
In the tunnel-shaped groove shown in Figure [3], the opening is widened at an angle θ
It is preferable to expand the hot water circulation pipe by increasing the efficiency of the construction work of the hot water circulation pipe. Spreading angle θ
is preferably in the range of 5 degrees to θ<45 degrees in order to eliminate the gap with the hot water circulation pipe, but it may be a wider angle for the construction work.

In addition, for each ton of core material, several grooves of appropriate width and depth are set on the underside of the core material in parallel or perpendicular to the groove 2.
It is preferable that the hot water circulation pipe 3 is made of rust-free +4 quality, such as plastic, copper, aluminum, etc.
A pipe made of stainless steel or the like can be used.

Furthermore, the heat sinks 4 and 17 are made of a material with good thermal conductivity, and can be metal plates such as galvanized iron plates, copper, aluminum, stainless steel, etc. For example, galvanized iron plates with a thickness of 006 m are used.
