[0006]

In the floor heating system configured as described above, by unitizing,
There is an advantage that the ease of assembly can be improved.
However, on the other hand, the following problems have occurred. That is, it is necessary to form the panel unit itself into a structure having rigidity to some extent by making it into a unit, but this causes an increase in cost. Moreover,
Since the unit panel arranged under the floor is not used as a rigid member, the cost increase cannot be utilized.

Further, it is necessary to connect heat transfer tubes between the panel units, but the number of connection points increases as the number of unit panels increases. Connection work is generally
Since it is carried out by brazing, it is necessary to perform flare processing on the end of each heat transfer tube, and it is also necessary to carry out construction with an electric brazing machine or torch.
For this reason, the work man-hours required for connection and the water man-hours required for the work for confirming the water leakage of the connection portion are increased.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a floor heating system which is highly reliable and has a low product cost while reducing the number of work steps during construction. .

[0009]

In order to achieve the above object, the present invention comprises a heat insulating material which is inserted between a plurality of joists provided under the floor at intervals and has a series of storage grooves on the surface thereof. A panel member, a support member for supporting the panel member to a joist, and a heat transfer tube that is bent and formed according to the shape and is inserted into the storage groove to allow a heating fluid to flow therein, There is proposed a floor heating device including a plurality of panel pieces each having a groove portion that constitutes the storage groove by combining the panel members in a continuous arrangement.

Further, in the above floor heating apparatus, it is effective to adopt a structure in which the support member is provided with a biasing means for bringing the panel member into close contact with the back surface of the floor plate material.

As the supporting member, a U-shaped fitting portion which is fitted onto the joist from above the joist by bending a flat plate material, and a joist provided on the opening end of the fitting portion It is preferable to integrally form a leaf spring-like urging means for projecting obliquely upward so as to cross the side face of the joist when mounted externally and mounting a panel member on the upper surface thereof. .

[0012]

According to the floor heating apparatus of the present invention, panel members having a groove portion formed on the surface of the heat insulating material are connected to each other so that the groove portions of the panel piece are connected to each other to provide a series of storage grooves. The heat transfer tube is bent and formed according to the shape of the storage groove and is inserted into the storage groove by forming a support member with a joist and supporting it in a wide range without performing the work of connecting the heat transfer tube. It becomes possible to carry out construction.

Further, if the support member is provided with the biasing means, the biasing means generates the biasing force so as to bring the panel member into close contact with the back surface of the floor plate material, so that the heat transfer property can be improved. Therefore, it is possible to impart the vibration insulating effect to the heat insulating material to absorb the vibration of the floor board material.

Such a supporting member integrally has a U-shaped fitting portion to be fitted on the joist by bending and forming a flat plate member, and urging means arranged at both ends thereof. Then, since the panel member placed on the biasing means formed in the shape of a leaf spring is supported by the joists, the elastic force of the biasing means allows the panel member to be brought into close contact with the back surface of the floor plate material. It can be realized by the configuration.

The panel member 2 is composed of a plurality of panel pieces 2a which are connected to each other. Each of the panel pieces 2a has a groove 5a formed on one side surface which is an upper surface thereof. The groove portion 5a is formed to have a depth and a width dimension suitable for accommodating the heat transfer tube 6 according to the cross-sectional shape of the heat transfer tube 6 to be accommodated therein.

Further, the groove portions 5a formed on the panel pieces 2a are the groove portions 5a of the panel pieces 2a which are arranged adjacent to each other.
A series of storage grooves 5 can be formed by being connected with. That is, one panel piece 2a has two groove portions 5a connecting the two different sides, and another panel piece 2a has one groove portion 5a having both ends on one side.
Are formed and arranged. Furthermore, these panel pieces 2
The aluminum foil 7 is provided on the side surface where the groove 5a of a is formed.
A sheet member having high heat conductivity such as is attached.

As shown in FIG. 2, the support member 4 is formed by bending a flat plate material such as a rectangular iron plate. That is, a fitting portion 4a bent in a U-shape is provided at the center of the flat plate material in the longitudinal direction, and both ends of the flat plate material arranged on both sides of the fitting portion 4a form an acute angle with respect to the side wall 4b of the fitting portion 4a. By bending the support part 4
c (biasing means) is provided. The support member 4 is attached to the joists 3 by fitting the fitting portions 4a from above the joists 3 arranged under the floor. As a result, the support portions 4c provided at both ends of the support member 4 are arranged so as to project obliquely upward from the side surface of the joist 3 to form a cantilever-shaped leaf spring.

In order to construct the floor heating system 1 thus constructed, first, the supporting members 4 corresponding to the respective panel pieces 2a are provided at intervals in the longitudinal direction of the joists 3 arranged at parallel intervals. Are fitted to the joist 3 by fitting the fitting portions 4a onto the joist 3.

In this way, the panel member 2 supported by the support member 4 on the joist 3 is constructed. After this,
By accommodating the series of heat transfer tubes 6 in the storage groove 5 while bending them according to the shape of the storage groove 5,
The floor heating system 1 will be constructed. Then, both ends of the heat transfer tube 6 are connected to a boiler (not shown), and the floor plate material 8 is laid from the upper surface of the panel member 2 to form a floor having the floor heating device 1.
