DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor heating panel for constructing a floor heating floor, and more particularly, to a directly attached floor heating panel laid directly on a concrete slab.

[0002]

2. Description of the Related Art There is a floor heating panel integrated with a floor finishing material used as a floor finishing material as shown in FIGS. 6 and 7. FIG. The floor heating panel 50 includes a panel base material 51 having a surface finishing material 52 such as a veneer adhered to a surface thereof, and a line heater 55 arranged in a predetermined heater pattern on a base material sheet 54 and the outer surface of the line heater. Heating element 53 in which a portion is thermally welded to base sheet 54
And a cushioning material 56 having a good cushioning property.
And the cushioning material 56.

[0003] The floor heating panel 50 includes a surface finishing material 52.
The heating element 53 is overlapped with the adhesive applied to the back surface of the panel substrate 51 to which the panel substrate 51 has been attached.
After the heating element 53 is attached to the heating element 53, the buffer material 56 is attached to the heating element 53 by superimposing the heating element 53 and the buffer material 56 with the adhesive applied to one of them. It is common to manufacture through a sticking process of, compared with a normal direct-attached flooring material that is manufactured by simply sticking a cushioning material to the back of the panel base material, There was a problem that it would increase.

[0004] Further, it is conceivable to manufacture a similar floor heating panel in a single sticking step by directly heat-sealing the wire heater to the surface of the cushioning material. However, the wire heater is heat-welded to the cushioning material. A new problem arises in that the cushioning material is sagged in the hot pressing process at that time, and the sound insulation effect that the cushioning material should originally achieve is lost.

Therefore, an object of the present invention is to provide a panel base, a heating element, and a cushioning material without lowering the sound insulation effect.
It is an object of the present invention to provide a floor heating panel that can be efficiently laminated in a single sticking process.

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a heating element having a line heater held on a base sheet, between a panel base made of a wooden board and a cushioning material. In the floor heating panel sandwiched between the above, the base sheet was formed of a material having good adhesive permeability.

[0007] The floor heating panel configured as described above,
After applying the adhesive to the back surface of the panel base material or the base sheet forming the heating element, if the heating element is sandwiched between the panel base material and the cushioning material, the adhesive easily penetrates the base sheet. Since the process shifts to the cushioning material side, the heating element can be adhered to both the panel base material and the cushioning material by a single attaching process.

As the base sheet formed of a material having good adhesive permeability, a nonwoven fabric having a high porosity can be used as in the floor heating panel according to the second aspect. In consideration of the permeability of the agent, the basis weight is 15 to 30 g / m ² as in the floor heating panel according to claim 3.
It is desirable to use a nonwoven fabric that is

Embodiments will be described below with reference to the drawings. As shown in FIGS. 1 to 3, the floor heating panel 1 is a directly attached floor heating panel laid directly on a concrete slab, and is embedded in a panel body 10 in the shape of a goose, and is built in the panel body 10. It comprises a heating element 20 and a power supply line 30 composed of a VVF cable.

The panel body 10 has a three-ply plywood or a five-ply plywood in which a heat equalizing sheet 13 made of aluminum foil or the like and a surface decorative material 14 made of a veneer or the like are sequentially laminated on the surface.
Formed by a panel base material 11 made of a wood board such as a ply plywood, and an extensible fiber aggregate in which a number of polyester fibers (polyethylene terephthalate fibers) adhered to the back side of the panel base material 11 are entangled. The heating element 20 is built in a state sandwiched between the panel base material 11 and the cushioning material 15.

As shown in FIG. 1, the panel base material 11 has four surface pieces 12 each having a pseudo groove 14a formed in a surface decorative material 14 and is shortly shifted in a longitudinal direction thereof. As shown in FIG. 2, a plurality of grooves (cuts) 11a extending in the lateral direction and a central portion in the longitudinal direction are formed on the back surface of the panel base material 11. A concave portion 11b for accommodating the power supply line 30 traversing in the hand direction is formed.

As shown in FIGS. 2 and 3, the heating element 20 has a basis weight of 15 to 30 g / m.
Substrate sheet 21 made of about ² spunbonded nonwoven fabrics
And a wire heater 22 that is wired on the base sheet 21 in a predetermined heater pattern, and an outer skin portion serving as an insulating layer is heat-welded to the base sheet 21.
2 so that the panel base material 1 contacts the cushioning material 15.
1 and the cushioning material 15 are adhered by an adhesive.

The power supply line 30 is disposed so as to traverse the panel body 10 in the short direction thereof while being housed in a concave portion 11b formed on the back surface of the panel base material 11. Are connected to connectors 31 for electrically connecting the floor heating panels 1 adjacent to each other in the lateral direction.

As shown in FIG. 3, a wire heater 22 is connected to the power supply line 30 via a conducting wire 32 and a thermostat 33. The thermostat 33 is formed on the back surface of the panel substrate 11. The power supply line 30 and the line heater 22 are housed in a concave portion (not shown), and are electrically disconnected or connected by detecting the temperature of the panel base material 11.

In order to manufacture the floor heating panel 1 configured as described above, as shown in FIG. 4, a urethane-based panel is provided on the back surface of the panel substrate 11 on which the heat equalizing sheet 13 and the surface decorative material 14 are sequentially laminated. After applying an adhesive C such as a resin or an epoxy resin, the heating element 20 is sandwiched between the panel base 11 and the cushioning member 15 so that the power supply line 30 is fitted into the recess 11 b of the panel base 11. When pressure is applied, as shown in FIG. 5, the adhesive C applied to the back surface of the panel base material 11 penetrates the base sheet 21 and reaches the cushioning material 15. The base sheet 21 of the heating element 20 is simultaneously attached to both the panel base material 11 and the cushioning material 15 by the adhesive C, and the floor heating panel as shown in FIG. 1 is completed.

As described above, in the floor heating panel 1, the base sheet 21 for holding the wire heater 22 is formed of a spunbond nonwoven fabric having a basis weight of about 15 to 30 g / m ² through which the adhesive can penetrate well. When the heating element 20 is sandwiched between the panel base material 11 and the cushioning material 15,
The adhesive C applied to the back surface of the panel base material 11 passes through the base material sheet 21 and easily moves to the cushioning material 15 side, and the heating element 20 is separated from the panel base material 11 and the cushioning material 15 by one bonding process.
The floor heating panel can be adhered to both sides without fail, and the same process as in the case of a normal direct-attached flooring material manufactured by simply attaching a cushioning material to the back surface of the panel base material. 1 can be manufactured.

In the floor heating panel 1 manufactured in this manner, since the wire heater 22 is not directly heat-welded to the cushioning material 15, the cushioning material 15 does not sag, and the cushioning material 15 is originally provided. The sufficient sound insulation performance is exhibited.

In this embodiment, the base sheet 21
Was formed by a spunbonded nonwoven fabric, but if sufficient permeability to the adhesive can be ensured,
Chemicarbide nonwoven fabric with fiber web bonded with adhesive,
Various nonwoven fabrics can be used, such as a thermal bonded nonwoven fabric bonded by self-adhesion or an adhesive fiber, and a needle punched nonwoven fabric in which the web is innumerably entangled and entangled with a special needle. However, even when such a nonwoven fabric is used, it is desirable to use a nonwoven fabric having a basis weight of about 15 to 30 g / m ² . If the basis weight is more than 30 g / m ² , it is not possible to secure a sufficient permeability to an adhesive generally used in the production of building materials, and the heating element 20 is cushioned by the adhesive C applied to the panel base material 11. This is because it is not possible to securely adhere to the wire heater 15, and if the basis weight is less than 15 g / m ² , a sufficient holding capacity for the wire heater 22 cannot be obtained. Therefore, it should be added that a nonwoven fabric having a basis weight exceeding 30 g / m ² can be used when the viscosity or the like of the adhesive used is small.

The base sheet 21 is not limited to the non-woven fabric described above, but may be a material such as a mesh sheet that allows the adhesive to easily penetrate from one side to the other side. If so, various materials can be used. However, it is needless to say that the base sheet 21 must be able to hold the wire heater 22.

In this type of floor heating panel, a groove (cut) is formed on the back surface of the panel substrate 11 in order to enhance the sound insulation performance.
Since the elasticity of the panel base material 11 is generally ensured by forming the base material 11 a, the base sheet 21 directly adhered to the panel base material 11 should not impair the elasticity of the panel base material 11. It is desirable to select a material that is as thin as possible within a range that can hold the wire heater 22 and that has good elasticity.

In this embodiment, the panel substrate 11
The case where the adhesive C is applied to the back surface of
The method is not limited to such a method, and the adhesive C can be applied to the base sheet 21 and the cushioning material 15.

In this embodiment, the panel base material 11 is used in which the four base pieces 12 are bonded to each other in the transverse direction while being shifted irregularly in the longitudinal direction.
The panel substrate 11 is not limited to these, and it is also possible to use a mere step-like or rectangular one in which the shift interval of the substrate pieces is constant. However, as in the present embodiment, the eaves-shaped panel substrate 1 in which the substrate pieces 12 are irregularly shifted in the longitudinal direction thereof.
The use of No. 1 has an effect that the seams between the panels are less noticeable as compared with the case of using a step-like panel substrate or a rectangular panel substrate in which the substrate pieces are shifted at regular intervals.

Further, as described above, the number of the substrate pieces 12 to be joined is not limited to four, and three, two, or five or more It is also possible to use panel substrates in which the pieces are joined to one another.

In this embodiment, the pseudo grooves 14a are formed in the surface decorative material 14 of each base piece 12 in order to make the seams between the panels less noticeable. However, the pseudo grooves 14a are not necessarily formed. No need.

In this embodiment, the connectors 31 are connected to both ends of the power line 30. However, the connectors need not always be connected, and the power lines 30 may be directly connected to each other. . However, the provision of the connector 31 has an effect that the work of connecting the power supply line 30 can be performed efficiently.
