DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cooling / heating panel in which a plate-like base made of a foamed resin is provided with a concave groove for embedding a heat medium flow pipe.

[0002]

2. Description of the Related Art In a panel for cooling and heating as described above, a heat medium flow pipe is buried in a concave groove of a plate-shaped base material, and a heat medium such as hot water or cold water flows through the heat medium flow pipe. Things,
As such a cooling / heating panel, a panel laid on a ceiling surface to distribute cold water through a heat medium distribution pipe and a floor heating panel laid on a floor surface to distribute hot water through a heat medium distribution pipe are known. . The floor heating panel described above will be described as an example. The plate-shaped base is made of a foamed resin such as polyethylene or polystyrene to reduce the weight of the floor heating panel and to reduce the weight of the plate-shaped base by using a small wooden board. Implanting joists, or
It is known to improve the strength of a floor heating panel by hardening a foamed resin.

[0003]

However, in the prior art, since the plate-shaped base made of foamed resin is exposed on the surface, its surface strength is not sufficient, and it is involved in the construction of panels for cooling and heating. When performing construction, a relatively hard plywood was required to prevent the surface of the cooling / heating panel from being damaged. When the cooling / heating panel is applied as a floor heating panel, the surface strength is not sufficient, and the selection range of the finishing material to be laid on the upper surface of the floor heating panel is greatly restricted.

[0004] In the prior art, small joists are embedded in the plate-like base material or the foamed resin is hardened in order to improve the strength of the cooling / heating panel. In the case where a small joist is embedded, the load at the time of installation is received only by the small joist part, that is, only a part of the cooling / heating panel, so that sufficient strength may not be obtained yet, and the foamed resin is hardened. Also in the case of a foamed resin, the harder the foamed resin, the higher the cost and the disadvantage that the cost is increased.

The present invention has been made in view of the above point, and an object of the present invention is to provide a cooling and heating panel capable of improving overall strength including surface strength while reducing costs. On the point.

[0006]

To achieve this object, according to the first aspect of the present invention, a recessed groove for embedding a heat medium flow pipe is provided in a foamed resin plate-like base material. In the cooling and heating panel described above, a hard upper thin plate is provided on the upper surface of the plate-shaped base material so as to cover the opening side of the concave groove. In other words, by providing a hard upper thin plate on the upper surface of the plate-like base material in a state of covering the opening side of the concave groove, the surface strength can be improved, and when performing work related to the construction of panels for cooling and heating, etc. In addition, a relatively hard plywood for preventing the surface of the cooling / heating panel from being damaged becomes unnecessary. In addition, even when applied to the floor heating panel, the surface strength can be improved, so that the selection range of the finishing material to be laid on the upper surface of the floor heating panel is widened.

According to the second aspect of the present invention, a hard lower thin plate is provided on the lower surface of the plate-shaped substrate. That is,
The load at the time of installing the panel for cooling and heating can be received by the entire lower surface of the hard lower thin plate, and sufficient strength as the panel for cooling and heating can be obtained without making the foamed resin of the plate-shaped base material hard. Therefore, the overall strength can be improved while reducing the cost.

According to the third aspect of the present invention, the heat conductive material is provided between the upper surface of the plate-shaped substrate and the upper thin plate and on at least one of the upper surfaces of the upper thin plate. In other words, by providing a heat conductive material between the upper surface of the plate-shaped substrate and the upper thin plate and at least one of the upper surfaces of the upper thin plate,
Since the heat from the heat medium flowing through the heat medium flow pipe is easily transmitted by the heat conductive material, the heat conductivity can be improved, and the heat of the heat medium can be effectively used.
