BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor heating apparatus capable of heating a room on a floor.

[0002]

2. Description of the Related Art Floor heating apparatuses that can heat a room by generating heat on a floor surface are becoming popular.
As one type of this floor heating device, there is a floor heating panel formed by incorporating an electric heating element on a floor surface, and the floor heating panel is used to form an indoor floor.

FIG. 2 shows an example of such a system.
Attach a joist 12 on top of 1 and construct a floor set, and pack a heat insulating material 13 such as glass wool between the joists 12,
By laying and fixing a plurality of floor heating panels 7 on the joists 2, the floor heating panel 7 constitutes an indoor floor.

[0004]

[Problem to be solved by the invention]
There was a problem that the construction of a floor group such as the Ohiki 11 and the joist 12 was required. For this reason, the floor heating panel 7 is directly adhered to a floor base such as a slab without performing a floor assembly.
A direct pasting method is being studied. However, when the floor heating panel 7 is directly attached on the floor base, the heat insulating material 13 cannot be provided below the floor heating panel 7 and the thermal efficiency is reduced. The sound on the floor is transmitted directly downstairs,
Furthermore, since wiring cannot be performed below the floor heating panel 7, the direct bonding method has not yet been adopted.

[0005] The present invention has been made in view of the above points, and an object of the present invention is to provide a floor heating apparatus which can install floor heating panels by a direct bonding method.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. The base panel 2 is made of a substrate having a size of 3 inches × 6 inches or 1 inch × 6 inches and a thickness of about 30 to 40 mm, and is formed in a U-shaped cross section having an open upper surface as shown in FIG. It is. A cushion material 3 made of an elastic material such as rubber or soft resin is provided on the lower surface of the base panel 2 by bonding or the like over the entire surface. The thickness of the cushion material 3 is preferably about 10 mm. The heat insulating material 1 is filled over the entire surface of the base panel 2. The heat insulating material 1 is not particularly limited, but a high-performance heat insulating material provided by the present applicant in JP-A-1-208376 can be used. This Japanese Patent Application Laid-Open
The heat insulating material provided in JP-A-208376 is a microporous body formed by molding powder particles, and it is necessary to use an ultrafine powder as the particle powder and to perform an anti-agglomeration treatment on the particle powder in advance. It is a feature. At least a part of the particle powder has a specific surface area of 4000 m ² /
g or more of ultrafine silica powder and / or ultrafine silica powder having a particle size of 60 ° or less is used, and the aggregation prevention treatment is performed using an organosilane compound such as an alkoxysilane compound, a chlorosilane compound, or a silazane compound. By pressing the particle powder under pressure, a microporous heat insulating material can be obtained. In this heat insulating material, the gap between the particle powders is small because the particle powders are ultrafine particles and are subjected to an anti-agglomeration treatment,
It has high heat insulation performance. In the center of the upper surface of the base panel 2 filled with the heat insulating material 1 as described above, a wiring groove 4 is provided so as to open upward over substantially the entire length. In the embodiment shown in FIG. 1, the heat insulating material 1 is covered with an electrically insulating cover plate 14 having low thermal conductivity, and the wiring groove 4 is formed at a bent portion of the cover plate 14.

On the other hand, the floor heating panel 7 has an electric heating element 6 such as a film heater laminated on the upper surface of a wooden substrate 15 and a heat equalizing plate 16 such as a metal plate laminated thereon. It is formed by stretching the floor surface plate 17. However, when directly attaching the floor heating panel 7 to a concrete slab, such as a concrete slab, without installing a floor structure such as a pulling or joist, first, the floor base 5
After adjusting the unevenness of the upper surface of the base material, a plurality of base panels 2 are laid on the floor base 5 and are attached and fixed by bonding or the like. Next, wiring work is performed through electric wires along the wiring grooves 4 of each base panel 2, wires are connected to the electric heating elements 6 of each floor heating panel 7, and each floor heating panel 7 is provided along each base panel 2. And placing the floor heating panel 7 on the base panel 2 and screwing wood screws from the floor heating panel 7 into the base panel 2 and concealing the heads of the wood screws with wooden plugs. ,
Each floor heating panel 7 can be mounted on each base panel 2, and the floor heating panel 7 can be directly attached to the floor base 5 via the base panel 2.

[0010] In the floor heating device constructed in this manner, even if a noise is generated on the floor heating panel 7 forming the floor, the noise is generated by the cushion material 3 provided on the base panel 2. Thus, it is possible to reduce the transmission of the sound of the floor surface to the floor floor 5 and to prevent the sound of the floor surface from directly transmitting downstairs. Further, the heat generated from the electric heating element 6 of the floor heating panel 7 can be prevented from escaping below the floor by the heat insulating material 1 provided on the base panel 2, and the heating efficiency can be increased and the running cost can be reduced. is there.
It is also possible to attach the floor heating panel 7 to the floor base 5 in a floor-standing manner. In this case, the thickness from the upper surface of the floor base 5 to the upper surface of the floor heating panel 7 is 100 to 150 mm.
It is not preferable because it makes the room space narrow. On the other hand, in the method of the present invention, the floor
The thickness from the upper surface of the floor to the upper surface of the floor heating panel 7 is 50 to 6
0mm is enough.

[0011]

[Effects of the Invention] As described above, the present invention provides a cushioning material on the lower surface of a base panel formed by providing a heat insulating material, directly fixes the base panel on a floor base, and incorporates an electric heating element. The floor heating panel is formed on the base panel, so that by attaching the base panel to the floor base, the heat insulating material provided on the base panel can secure the heat insulation property of the lower side of the floor heating panel. , and buffer the noises cushion material provided on the base panel can be prevented from being transmitted to the downstairs, yet over the insulation material with an electrically insulating cover plate
Cover, opening into the upper surface of the underlying panel at the bent portion of the cover plate
Due to the provision of the wiring trench, when using a wiring trench can perform wiring for power supply to the floor heating panel co
In addition, the wiring groove can be formed with an electrically insulating cover plate.
To ensure the electrical insulation of the wires routed in the wiring grooves
This makes it possible to directly attach the floor heating panel to the floor base through the base panel.
