Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a floor heating device that heats a room by flowing hot water through pipes placed under the floor surface. Conventionally, in this type of pipe shown in Fig. 3, when a pipe made of synthetic resin is used, as shown in Fig. 4, the wooden plywood or the like which is thermally deformed by hot water and forms the floor surface placed on the pipe, as shown in Fig. 4, is used. This has the drawback of pushing up the floor, making the floor uneven, and causing squeaks when walking.

The present invention seeks to eliminate the above drawbacks.

The present invention will be explained below based on an embodiment shown in FIGS. 1 and 2.

Reference numeral 1 is a pipe made of synthetic resin, whose cross section is elongated vertically in the vertical direction, and whose central portion expands outward when internal pressure is applied.

2 is a heat conduction plate (used to spread the heat of hot water uniformly below the floor surface) made of a heat conduction iron plate, aluminum plate, copper plate, etc. It is vertically long, widens in the center, and has an upper opening. A fitting groove 3 having a narrow cross section is provided. The width of the upper opening of the fitting groove 3 is formed to be approximately equal to or larger than the width of the pipe 1.

The heat conductive plate 2 is a heat insulating material 4 on the floor base of the building structure.
The pipe 1 is stretched through the fitting groove 3, and the pipe 1 is fitted into the fitting groove 3. A floor plate 5 made of wooden plywood, metal plate, etc., which serves as a floor plate, is stretched over the heat conductive plate 2, and a carpet 6 is stretched on the floor plate 5.

Since the pipe 1 is fitted with its vertically long vertical direction aligned with the vertical direction of the fitting groove 3, the fitting operation can be easily carried out as is or by applying a slight external pressure to reduce the width. After that, even if the pipe 1 does not expand and deform due to thermal expansion etc. when hot water is passed through it, the pipe 1 does not become circular and expands, so the pipe 1 becomes narrow. It does not come off from the upper opening of the fitting groove 3, and therefore the floor surface is reliably prevented from rising.
