DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a floor heating panel having a built-in heating element.

[0002]

2. Description of the Related Art As a heating floor structure using a floor material having a built-in heating element, the one shown in FIG.
-16463). This heating floor structure has the following technical means: a long heating floor material A in which the surface heating element layer 3 is laminated and integrated with the middle layer; A recess 9 is provided near the end. The lead wire 5c of the control device such as the surface heating element layer 3, the control component, and the ground is drawn out into the recess 9. A heat generating floor material provided with a groove 10 communicating with at least one side surface from the recess 9 is housed in the recess 9 by connecting the lead wires 5c to each other, and the recess 9 is placed on the upper surface of the floor base material. The space is formed by the recess 9 and the floor base material. That is, the technical means described above is adopted. In FIG. 5, 1 is a floor material main body, 2 is a frame material, 6 is a surface material, 7 is a heat insulating material, and 8 is a back surface material.

In the heating floor structure of the aforementioned Japanese Utility Model Publication No. 6-16463, a recess 9 is provided, a power supply, a controller, and a lead wire 5c of the heating floor material A are connected to each other through a groove 10, and further into the recess 9. After accommodating the connection portion, the heat generating floor material A is directly constructed on a floor base material such as a plywood or a concrete slab.

[0004]

However, in the above-described heating floor structure of Japanese Utility Model Publication No. Hei 6-16463, since the lower end of the recess 9 is open to the outside, after the connection portion is accommodated in the recess 9, When the recess 9 is laid so as to face the upper surface of the floor base material, the connection portion may fall down from the lower end opening of the recess 9 and fall out of the recess 9. In such a case, the heat generating floor material A laid on the floor base material must be lifted and the connection portion must be accommodated in the recess 9 again, and the construction is troublesome.

The present invention has been made in view of the above circumstances, and has a built-in heating element and a hollow portion inside.
It is an object of the present invention to provide a floor heating panel in which a lead wire of a heating element is housed in the hollow portion, wherein the floor heating panel is easy to perform.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a floor having a built-in heating element, a hollow portion inside, and a lead wire of the heating element housed in the hollow portion. Heating panel, where it faces the cavity of the back material
A notch with three consecutive sides of a square is formed.
If the back material is cut by this cut,
In addition, the backing material is applied to the remaining one side of the square.
And continuous inside and outside of the cut
The inside is configured with a lid that can be opened and closed.
The part is formed with a saw-tooth-shaped part, a wavy-line part or an uneven linear part,
The lid has an insertion hole for inserting a finger or the like.
A panel for floor heating .

In the floor heating panel of the present invention, since the lower end of the cavity accommodating the lead wire of the heating element is closed by the back surface material, the lead wire does not fall down from the cavity portion and fall off during construction. . When operating the lead wire, the operation may be performed by opening the lid. Therefore, according to the floor heating panel of the present invention, the construction work becomes extremely easy.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a partially omitted bottom view of a floor heating panel according to the present invention, FIG. 2 is a partially omitted bottom view showing a state where a back material of the panel is removed, and FIG. FIG. 2 is a schematic cross-sectional view of the panel along the line 1A-A of FIG.

The floor heating panel of this embodiment has a surface material 2, a heating element 4 and a backing material 6 laminated thereon, and has a cavity 8 formed at one end in the longitudinal direction. Are accommodated. The front surface member 2 is formed of a wooden board, and the back surface member 6 is formed of cardboard. The heating element 4 is a sheet-shaped electric low-temperature heating element that generates heat when energized, and has a lead wire 10.
Is connected to a connector 12. Furthermore, surface material 2
A connector accommodating space portion 14 for accommodating the connector 12 at the time of construction is formed at three locations beside the hollow portion 8.

In the floor heating panel of this embodiment, three continuous rectangular sides a, b, c
Is formed, and this cut 1 is formed.
6, the back material 6 is cut, and the back material 6 is continuous inside and outside of the cut 16 at a portion forming the remaining one side d of the square.
The inside of 6 is configured as a lid 18 that can be opened and closed. In addition, a saw blade 20 is formed in a part of the cut 16, and an insertion hole 22 for inserting a finger or the like is formed in the cover 18. Further, a bending line processing 24 is applied to the portion d of the back material 6 so that the lid 18 can be easily opened.

When the floor heating panel of this embodiment is constructed,
First, the lid 18 is opened, the connector 12 is accommodated in one of the three connector accommodating spaces 14 according to the construction mode, and after the lid 18 is closed, a floor heating panel is laid on the floor substrate. is there.

Therefore, according to the floor heating panel of this embodiment, the lead wire 10 of the heating element 4 does not fall down from the cavity 8 and falls off, and the construction work becomes extremely easy. In this case, in the floor heating panel of this example, since the saw blade portion 20 is provided in a part of the cut 16, the lid portion 18 of the back material 6 and the outside thereof come into close contact with each other at this portion, Since the lid 18 is well engaged with the outside thereof, the lid 18 does not open even if the panel is turned upside down during construction.

In this embodiment, the back material 6 is made of cardboard, but the back material can be made of any other material such as a plastic plate or a wood board. Further, the saw blade-shaped portion 20 for improving the system name of the cover portion 18 of the back material 6 and the outside thereof may be a wavy line portion, an uneven line portion, or the like.

[0014]

According to the floor heating panel of the present invention, since the lower end of the cavity accommodating the lead wire of the heating element is closed by the back surface material, the lead wire falls down from the cavity portion during construction and falls off. There is no. When operating the lead wire, the operation may be performed by opening a lid formed on the back surface material. Therefore, the floor heating panel of the present invention is extremely easy to perform.
