Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a floor structure set at a predetermined height from a floor base such as a concrete slab.
The present invention relates to a floor heating floor structure in which floor heating is incorporated in a so-called dry double floor.

[0002]

2. Description of the Related Art In a conventional floor structure, support legs are provided at least at four corners of a floor base panel of a predetermined size, these are laid on a floor base, and a piling material is provided on a plurality of floor base panels. In addition, a heat insulating material was laid on the sacking material, and a finishing material was laid thereon. A groove for hot water piping is formed on the upper surface of the heat insulating material or the lower surface of the finishing material, and the hot water piping is arranged in this groove.

[0003]

The conventional floor base panel has a predetermined size, for example, about 910.times.1820 (mm). Therefore, it is necessary to provide support legs at the center other than the four corners. However, there is an inconvenience that it is difficult to adjust the level of the floor base panel. Further, in the case of using a rectangular floor base panel, the material used is increased, and the cost is increased.

Accordingly, an object of the present invention is to provide a floor heating floor structure which simplifies the underlying structure, facilitates leveling, and can achieve a significant cost reduction.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above-mentioned object, according to the present invention, a plurality of supporting legs are attached to the lower surface of a large pulling material, and the large pulling material is set at a predetermined height from a floor base by these supporting legs. A heat insulating material is mounted on the large pulling materials which are supported and arranged in parallel at a predetermined interval so as to be orthogonal to these large pulling materials, and a groove for hot water piping is formed in the heat insulating material. A pipe is arranged, and a floor finishing material is provided on a heat insulating material.

[0006]

Preferred embodiments of the present invention will be described below with reference to the accompanying drawings.

In the embodiment shown in FIG. 1, a plurality of supporting legs 2 are attached to the lower surface of a large pulling material 1, and the large pulling material 1 is supported by these supporting legs 2 at a predetermined height from a floor base 3 such as a concrete slab. The large attracting materials 1 are arranged side by side at predetermined intervals. In the support leg 2, a cushion rubber 2A is landed on a floor base 3, and the cushion rubber 2A and the large traction material 1 are connected by a height-adjustable support bolt 2B.
On the large pulling materials 1 arranged in parallel, a heat insulating material 4 is attached so as to be orthogonal to these large pulling materials 1. On the heat insulating material 4, a floor finishing material 5 is provided. The floor finishing material 5 and the heat insulating material 4
And a hot water pipe (to be described later) is provided.

FIG. 2 is a perspective view of the heat insulating material 4, in which a hot water pipe groove 4A is formed on the surface of the heat insulating material 4, and on the back surface, the strength of the heat insulating material 4 in the longitudinal direction is improved. A groove 4B (reinforcing means) is formed.

FIG. 3 shows a cross section of FIG. 2, in which a hot water pipe 6 is disposed in the hot water pipe groove 4A. In this example,
The heat insulating material 4 used was a resin hollow panel 40 in which a foamed resin 41 was filled. The hollow panel 40 can be easily formed by blow molding or the like. The foamed resin 41 can be filled at the time of molding the hollow panel 40 or after the molding.

FIG. 4 shows an example in which a ridge 4C is formed as a reinforcing means of the hollow panel 40 instead of the groove 4B described above. The groove 4B and the ridge 4C can be used together.

In the embodiment shown in FIG. 5, plywood, that is, a wooden board 7 is attached to both ends (only one end is shown) of the hollow panel 40 along the longitudinal direction at both ends of the hollow panel 40 to reinforce the hollow panel 40. FIG. The wooden board 7 provided on the lower side is attached to the large pulling material 1 with a nail 8. In this embodiment, a soaking plate 9 is provided between the hot water pipe groove 4A and the hot water pipe 6. As the soaking plate 9,
For example, aluminum or iron having high thermal conductivity can be used.

The embodiment shown in FIG. 6 shows an example in which an iron plate 10 is provided on the back side of the hollow panel 40, and the iron plate 10 serves as a reinforcing means for the hollow panel 40.

When a resin hollow panel 40 is used as the heat insulating material 4, the resin material tends to expand due to a rise in temperature. On the other hand, since the large attracting material 1 and the finishing material 5 are usually wooden materials, they tend to dry and shrink due to a rise in temperature. In order to absorb this difference, a structure as shown in FIGS. 7 to 9 is employed. That is, a long hole 7A is formed in the wooden board 7,
A screw 12 having a sleeve 11 is inserted into the elongated hole 7A, and the screw 12 is screwed into the hollow panel 40. Alternatively, a stepped screw 12 'as shown in FIG. 9 can be used.

FIG. 10 shows an embodiment in which a hot water pipe 6 is embedded in a part of the inside of a heat insulating material 4. The hot water pipe 6 may be inserted at the time of molding the heat insulating material 4, or the pipe path 60 may be formed, and the hot water pipe 6 may be inserted from both ends of the pipe path 60.

[0015]

As described above, according to the present invention, instead of using a conventional rectangular floor base panel having a predetermined size, a long large pulling material is used. Is supported at a predetermined height from the floor base by supporting legs, and a heat insulating material is attached on the large pulling materials arranged in parallel at a predetermined interval so as to be orthogonal to these large pulling materials, and the heat insulating material is used for hot water piping. Since the grooves are formed, the hot water pipes are arranged in the hot water pipe grooves, and the floor finishing material is provided on the heat insulating material, the leveling of the large-scale material can be easily performed, the base structure can be simplified, and the cost can be reduced. Further, in the case where the heat insulating material provided in the direction orthogonal to the large drawing material uses a resin hollow panel, since the strength is insufficient, a groove or / and a ridge is provided as hollow panel reinforcing means, or a metal plate or By attaching the wood board to the hollow panel, sufficient reinforcement can be achieved. The heat insulating material provided with the reinforcing means and the large pulling material are formed in a cross-girder shape, and this cross-girder-shaped floor base structure can exhibit strength as a floor surface.
