BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor heating system which can be constructed at low cost and which can save labor.

[0002]

2. Description of the Related Art As a floor heating device for heating the entire room from the floor surface or for heating a part of the floor surface, there is a so-called ondol, which uses high-temperature smoke passing through a flue provided under the floor. It has been frequently used.

[0003]

However, a floor heating system using a heating medium such as hot air and oil such as ondol requires many members such as stones to form its flue, and the construction work is difficult. This tends to be complicated, which causes an increase in cost, requires a great deal of time and labor for construction, and is inferior in workability.

The present invention is based on the fact that a heating floor section having a heater section and a surface material whose upper surface is the floor surface is arranged on a substrate, and a floor having a heating function can be formed while reducing the cost. Moreover, it is an object of the present invention to provide a floor heating device that can save the construction work.

[0005]

In order to achieve the above-mentioned object, a floor heating apparatus of the present invention comprises a substrate laid on a floor base material, and a heater portion arranged on the substrate and electrically heated. And a heating floor portion having a surface material covering the heater portion and having an upper surface serving as a floor surface, the substrate is formed of a cuttable wood material, and a concave portion for facilitating the cutting is formed on the lower surface. They are installed side by side.

[0006]

As described above, the floor heating device is composed of the substrate laid on the floor base material, and the heated floor portion disposed on the substrate and having the heater portion and the surface material whose upper surface is the floor surface. Therefore, by placing this floor heating device on the floor base material,
It is possible to conveniently form a floor having a heating function, save labor in construction, reduce the number of members, and reduce production costs and construction costs.

Further, since the substrate is formed of a wood material that can be cut using a plane, for example, and a concave portion for facilitating the cutting is juxtaposed on the lower surface, the thickness of the substrate can be easily adjusted on site. It can be adjusted, and the level accuracy of the floor surface formed by the upper surface of the surface material can be improved.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. In the figure, a floor heating apparatus 1 of the present invention comprises a substrate 2, and a heating floor portion 5 having a heater portion 3 and a surface material 4, and the substrate 2 is formed of a wood material capable of being cut off, and on the lower surface, The concave portions 6 ... Which facilitate the excision are juxtaposed.

The substrate 2 is laid on the upper surface of the flat floor base material A. In this example, the floor base material A is integrally formed by being attached to the upper surface of a frame formed by joining a frame material B made of channel steel as shown in FIG. A portable floor panel P is formed. This floor panel P is
For example, the side portions thereof are bolted to the lattice beam 15 so that they are bridged horizontally. The upper chord member 16 of the lattice beam 15 has a wall W in the room in which the floor heating system 1 is arranged.
The wall panel 17 that forms the wall is erected.

On the floor base material A, flat rectangular floor boards C ... Are laid out vertically and horizontally in a tile shape, and are placed on the floor board C. For example, in front of the kitchen stand 19 and the floor base material. On the upper surface of the material A, as shown in FIGS. 1 and 2,
Since one floor board C is not laid, an installation portion A1 for installing the floor heating device 1 is formed in which the upper surface of the floor base material A is exposed.

The thickness of the substrate 2 is smaller than the thickness of the floor board C.

Since the concave portions 6 ... Are arranged in parallel on the lower surface of the substrate 2 made of wood material in this manner, the lower surface can be easily cut off using a plane, and the thickness of the substrate 2 can be adjusted conveniently. (If the lower surface is flat, it is extremely difficult to cut with a plane, and it is also difficult to cut evenly so that it is horizontal.)

A heating floor portion 5 is arranged on the substrate 2. As shown in FIGS. 2 and 3, the heating floor portion 5 has a lower sheet body 20 made of, for example, felt, which has the same rectangular shape as the substrate 2 in the plane.
