[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wood-based heating flooring material, and more particularly to a wood-based heating flooring material using a heater wire in a general flooring for home use.

[0002]

2. Description of the Related Art FIG. 7 shows a conventional wooden heating floor material (hereinafter referred to as "heating floor material") from the back side. The heating floor material 51 includes a wood-based surface material 101 that serves as a main body of the heating floor material 51 and also functions as a decorative plate, and a frame 10 provided on the periphery of the back surface thereof.
2, a heater wire 103 laid in the frame 102 in a U-shaped manner, and a power supply wire 104 connected to both ends of the heater wire 103.
And a grounding part 105 and a ground wire 106 connected to the grounding part 105. Heater wire 103, power supply wire 10
Wirings such as 4, the ground portion 105, and the ground wire 106 are covered with an aluminum soaking material (not shown) and further sealed with hard urethane (not shown) to form a heater unit.

The ground line 106 connected to the power line 104 and the ground section 105 is connected to the concave connector 107 and the convex connector 108 via the wirings 130 in the spaces provided on the left and right sides of the frame 102, respectively. There is. The concave connector 107 can be pulled out from an arbitrary opening 109 out of the three openings 109 provided on the upper side, the lower side, and the left lateral side of the left space of the frame 102. The convex connector 108 can be pulled out from an arbitrary opening 110 out of the three openings 110 provided on the upper side, the lower side, and the right lateral side of the right space of the frame 102.

With the above-described structure, the plurality of heating floor members 51 are provided with the concave connectors 107 provided at the left and right ends thereof.
Is electrically connected to the adjacent heating floor material 51 by the convex connector 108 and the heating floor material 51 from the power source (not shown).
Used to supply power to.

When power is supplied to these heating floor materials 51 from a distribution board or the like (not shown), a power cable such as VVF is generally used for indoor wiring from the distribution board to the heating floor materials 51. used. Since this power cable has a diameter larger than the electric wire used for the wiring 130 of the heating flooring material 51, the conventional concave connector 107 and convex connector 108 for connecting the heating flooring materials 51 cannot be applied. . In addition, since a connector that can be used for a power supply cable such as VVF cannot be accommodated in the thin heating floor material 51 in recent years, when using this connector, the wiring 103 and the like should be provided below the heating floor material 51. It needs to be pulled out and placed. Therefore, an extra space is required under the floor, and there is a possibility that the heating floor material 51 cannot be constructed when the area directly under the heating floor material 51 is concrete. Therefore, in the conventional heating floor material 51, only the first heating floor material 51 for pulling in the power cable is used as the power source heating floor material, and the specifications are different from those of the other heating floor materials 51. Among them, a one-touch type terminal block was used, which was fixed only by inserting the conductor of the power cable into the direction in which the power cable was pulled.

[0006]

However, according to the conventional heating flooring material, it is necessary to manufacture and manage heating flooring materials of two different types, that is, a normal heating flooring material and a heating flooring material for power supply. Therefore, there is a problem in that manufacturing and management efficiency is poor and costs are high.

[0007] Generally, the installation work of the heating floor material is divided into woodwork performed by a carpenter and electrical work performed by an electrician. When the conventional one-touch type terminal block is used, the heating floor material itself is Installation and connection of concave and convex connectors between heating floor materials are woodwork, and cable ends are
The work of inserting the conductor into the terminal block is an electrical work. Therefore, in the conventional heating floor material, these two operations overlap, so that it is necessary to make adjustments so that the respective steps of woodworking and electrical work can be performed at the same time, which is troublesome.

Further, the connectors for the heating flooring materials are all processed and installed in the factory in order to facilitate the construction at the site, and the products are manufactured in the form of simply connecting the connectors at the site. It is decided that a specific heating floor material will be used for power supply. Normally, in heating floor installation work, the surface pattern, such as the pattern of wood grain or the brightness of the colors, differs for each heating floor, so before the installation work, temporarily arrange them once, and the pattern will not look strange. The order of arrangement is changed. However, at the time of this work, one heating floor material for the power supply has already been decided, so it is necessary to consider the order in which other heating floor materials are arranged with this heating floor material for the power source as the base point. There was a problem that the work was difficult and inefficient.

Therefore, an object of the present invention is that it is not necessary to distinguish a normal heating flooring material from a heating flooring material for power supply, workability of construction is good, and wood construction and electrical construction can be completely separated. It is to provide a wood-based heating floor material.
