Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a floor heating device of a hot water piping system using a plurality of hot water pipes.

[Prior Art and Problems] Conventionally, a floor heating device of a hot water piping system using a hot water pipe for circulating hot water is known. As a hot water pipe that can be used in this type of floor heating device, a rigid pipe using a copper material or a hard synthetic resin material, and an elastic pipe using an EPDM rubber or the like are known.

By the way, this type of hot water pipe repeats a normal temperature (low temperature) state when hot water is not supplied or supplied, and a high temperature state generated when hot water is supplied or supplied. Thus, repeated radial and axial thermal expansion and contraction of the tube wall occurs in the hot water pipe in a relatively large manner. When such thermal expansion and contraction occurs in the radial direction of the pipe, the thermal expansion and contraction of the hot water pipe in the radial direction causes cracks in mortar or concrete on the floor surface. In addition, when the above thermal expansion and contraction occurs in the pipe axial direction, the thermal expansion and contraction of the hot water pipe in the axial direction may cause damage to the connecting portion of the hot water pipe, causing a fatal problem such as water leakage, or Cracks such as pipe covering mortar extending along the pipe occur. In particular, since the building has a semi-permanent element, it is actually extremely difficult to replace or renovate the hot water pipe once constructed, and maintaining the durability of the hot water pipe is actually the most important issue. .

The present invention has been made to provide a floor heating device having a novel structure capable of solving such problems existing in the related art. It suppresses the thermal expansion and contraction and pressure expansion in the radial and axial directions of the hot water pipe caused by the fluctuation of the pressure in the pipe, improves the pressure resistance and durability of the hot water pipe, and reduces cracks in the self-leveling material covering the hot water pipe. To provide an inexpensive floor heating device capable of reliably preventing and significantly simplifying the operation of positioning and fixing a hot water pipe to a construction surface and realizing a smooth construction of a self-leveling material flowing and spreading process. It is in.

[Means for solving the problem]

And a base sheet (10) interconnecting the heater units (H1, H2), wherein the expansion-contraction member (3c) is made of a large number of discontinuous thin thread materials, and the thread material is The base sheet (10) is distributed over the entire circumference of the pipe wall of the hot water pipe (2c) in a cross section of the hot water pipe (2c) so as to increase the pressure resistance of the hot water pipe (2c). Has a flat lower surface that interconnects lower portions of adjacent hot water pipes (2c) and can be laid on the construction surface (21, 23), and the heater unit (21, 23) with respect to the construction surface (21, 23).

[Action]

According to the floor heating device (20) of the present invention, the expansion / contraction member (3c) is embedded in the elastic hot water pipe (2c) made of elastic rubber or synthetic resin by integral molding. The anti-stretch material (3c) is made up of a large number of discontinuous thin yarns, such as short fibers embedded in an elastic material, and the numerous thin yarns are used to increase the pressure resistance of the hot water pipe (2c). In the cross section of the hot water pipe (2c), it is distributed over the entire circumference of the pipe wall of the hot water pipe (2c). Therefore, in accordance with the temperature change of the pipe wall of the hot water pipe due to the passage / non-flow of high-temperature water to / from the hot water pipe (2c) and the fluctuation of the pressure in the pipe, the thermal expansion and contraction of the hot water pipe (2c) in the radial and axial directions and When swelling etc. occurs,
The floor heating device having the above configuration suppresses expansion and contraction or expansion of the hot water pipe (2c) in both the radial direction and the axial direction by the expansion and contraction preventing action or expansion preventing action of the expansion and contraction preventing member (3c) with respect to the elastic material. Thereby, it is possible to reliably prevent the hot water pipe (2c) and the connection portion thereof from being damaged, and to induce cracks in the self-leveling material (24).

Moreover, according to the above configuration, the lower portions of the plurality of parallel pipes (hot water pipes) are interconnected by the base sheet (10), and the flat lower surface that can be laid on the construction surface (21, 23). The base plate (10) having the function as a means for positioning the heater units (H1, H2) with respect to the work surface (21, 23). Therefore, not only can the pipe laying work for laying a plurality of hot water pipes on the construction surface (floor base surface) be greatly simplified, but also the positioning and fixing of the hot water pipes with respect to the construction surface become possible, so that the self-leveling material can be continuously poured. In the process, the floating, relative displacement or unevenness of the hot water pipe (2c) is reliably prevented, and the self-leveling material casting process, which is designed to be extremely thin (generally, approximately 20 to 25 mm or less in thickness), is required. It can be constructed smoothly.

As shown in FIG. 2, a large number of fine thread materials are distributed over the entire circumference of the pipe wall of the hot water pipe 2c in the cross section of the hot water pipe 2c so as to increase the pressure resistance of the hot water pipe 2c. As an anti-stretch material, a fiber material that is strong in heat resistance and stretch resistance, and that is strong against chemicals and the like is desirable. Thereby, the thermal expansion / contraction and expansion of each hot water pipe 2c constituting the hot water pipe heater 1c are suppressed, and the pressure resistance and durability of the hot water pipe 2c are enhanced.

FIG. 2 shows that each of the hot water pipes 2c has an elastic member 3c.
This is for the purpose of exemplifying a production mode for embedding the device, and therefore does not prevent application of the embodiment according to the modified example of the present invention. For example, for the hot water pipe 2c ...
A heat insulating material layer or the like may be further laminated to form a hot water pipe 2c that does not substantially need to keep heat.

Since it can be implemented by easy and simple construction, floating, relative displacement or unevenness of the hot water pipe 2c in the subsequent self-leveling material flowing and casting process is reliably prevented,
In general, the flow of the self-leveling material, which is designed to have a very small thickness (generally, a thickness of about 20 to 25 mm or less), can be smoothly performed.
