The electric heating element 23 disposed between the back member 22 and the front member 21 has a conventionally known structure including a wire heater 23a, a thermostat 23b, an aluminum foil 23c, and the like. Power is supplied from an external power supply. The back surface member 22 has a plane shape substantially the same as the back surface shape of the front surface member 21 and is formed by plywood so as to overlap the back surface of the front surface member 21.

As shown in FIG. 2, the built-in floor heating panel 20 is fixed at the side where the female nut 26 is provided, as shown in FIG. Projection part 2 formed to project downward
8 is directly fixed to the construction surface 4 by the screw 6 penetrating from the upper surface, and the protruding portion 28 through which the screw 6 has penetrated forms the embedded floor heating panel 2 adjacent to the left.
It is covered by a 0 "storage part 27". Further, the floor heating panel 20 covers the protruding portion 28 'of the adjacent floor heating panel 20' with a storage portion 27 cut inwardly below the male 25 on the side where the male 25 is provided. , The male floor 25 adjacent to the floor heating panel 20 ′
Of the projecting portion 2 fixed to the working surface 4 of the adjacent floor heating panel 20 '
It is indirectly fixed to the construction surface via 8 '.

With the structure for fixing the built-in floor heating panel 20 configured as described above to the construction surface 4, a plurality of floor heating panels 20. . . 6 are laid side by side on a construction surface 4 made of a base plywood (abandoned plywood) provided on a floor foundation surface such as a concrete slab as shown in FIG. 6, and a floor heating structure is constructed. When constructing the floor heating structure, according to the area and shape of the floor surface to be laid,
A built-in floor heating panel 20 and a floor panel 3 having the same shape as the built-in floor heating panel 20 and having no electric heating element
0 and the required number of sheets are prepared. First, the floor panel 30 having no electric heating element is cut into two, and one of the cut floor panels 30a is arranged at one end of the floor surface to be constructed. A screw 6 is penetrated from the upper surface of a protruding portion 28 'of the floor panel 30a projecting below the female nut 26' to the work surface and is fixed to the work surface.

Next, the floor panel 3 fixed to the construction surface
A single floor heating panel 20 is placed on the construction surface in accordance with the step-like short side having a protruding portion 28 ′ through which the screw 6 of No. 0a penetrates. The projecting portion 28 ', through which the screw 6 of the floor panel 30a has passed, is covered by the storage portion 27 cut inward downward, and the projecting portion 2
The female nut 26 ′ above 8 ′ and the male nut 25 above the storage part 27 are engaged to fix the floor heating panel 20. The screw 6 penetrates from the upper surface of the protruding portion 28 formed to protrude, and the floor heating panel 20 is fixed on the construction surface 4.

Further, the fixed floor heating panel 20
Of the floor heating panel 20 "is covered with the storage portion 27" of the adjacent floor heating panel 20 ", and the female member 26 of the fixed floor heating panel 20 is fixed to the male member 25 of the adjacent floor heating panel 20". After engaging the "", the projecting portion 28 "of the adjacent floor heating panel 20" is fixed to the construction surface 4 by penetrating the screw 6, thereby repeating a predetermined number of floor heating panels 20. . . . Is fixed to the construction surface 4.

The same operation is sequentially repeated as described above, and a predetermined number of floor heating panels 20. . . After laying, the other floor panel 30b without the cut electric heating element
Is fixed to the other end of the floor by the same operation,
One row of floor heating structure is formed. The same operation is repeated for the row adjacent to the row, so that the floor heating panels 20. . . Is laid.

The floor panel 30 having the same shape as the built-in floor heating panel 20 and having no electric heating element is used as in the case of the present embodiment because the floor has a longitudinal end formed in a step shape. In the case of the heating panel 20, it cannot be laid in a state in which it is in close contact with the linear edge of the square laying floor, and in such a case, it is required to cover the entire area of the square laying floor. This is because the panel can be laid in close contact with the edge.

Each of the cut floor panels 30b. . . May be configured such that a groove for accommodating electric wires is formed on the back surface thereof in the length direction thereof, and the wiring between the floor heating panel 20 side and the building side is connected therethrough. In addition, it is preferable from the viewpoint of disaster prevention that the floor heating panel 20 is laid almost all over the center of the laid floor surface and the heating element is not positioned near the edge from the viewpoint of disaster prevention, as shown in FIG. In addition, the rows of the floor panels 30 that are not cut may be arranged on both sides of the laying floor.

The structure for fixing the built-in floor heating panel of the present invention to the construction surface has been described in accordance with one embodiment. A modification of this embodiment will be described with reference to FIGS. Embedded floor heating panel 2 as described above
0 is generally formed of a woody material as a whole, and therefore shrinks when heated by heating, and abutting portions (short lengths) between the respective floor heating panels 20, particularly in the longitudinal direction (that is, in the same row). (A side portion).

In order to prevent this, as shown in FIG.
It is only necessary to fix the whole floor heating panel with screws or the like, or to bond the entire floor heating panel to the entire surface. However, if a defect occurs on a part of the floor, It becomes difficult to remove and replace only the floor heating panel. Therefore, in the fixing structure of the built-in floor heating panel to the construction surface according to the present invention, as shown in FIG. 3, the protruding portion 28 formed below the female nut 26 on the short side of the floor heating panel 20 is formed. An adhesive 31 is applied, and as shown in FIG. 4, the protruding portion 28 and the protruding storage portion 27 "of the adjacent floor heating panel 20" are bonded to the adhesive 31.
By fixing with the use of a screw, the gap is generated between the panels due to the contraction of the panel at the time of heating even if the fixing is performed only by the screw 6 only at the protruding portion 28 formed on the short side of each floor heating panel. In the case where a defective portion occurs on a part of the floor surface, the floor heating panel at the defective portion can be replaced by cutting and removing one row.

However, in a floor heating structure using a fixed structure of an embedded floor heating panel having a small portion directly fixed to a construction surface by such a screw or the like, the back surface of the floor heating panel is entirely adhered by an adhesive. It is conceivable that the connection between the construction surface made of a base material such as a joist or a base plywood and the floor heating panel is weaker than that of the above, and floor noise occurs during use.

Therefore, as shown in FIG. 3 and FIG. 4, a layer 32 made of Japanese paper, nonwoven fabric, titanium paper or the like having a very low inter-sheet peel strength is preferably provided on the lower surface of the backing material 22 of each floor heating panel (preferably). Are provided in the form of cardboard of 50 g / m ² or more), and the floor heating panels 20 are adhered to the construction surface 4 through the layer 32 so that the lower surface of each floor heating panel 20 is on the construction surface 4. When the floor heating structure is found to have a defective part on a part of the floor surface, the floor heating panel 20 has a screw 6. , And the floor heating panel of the portion can be removed by peeling off the layer 32.

As mentioned above, the fixing structure of the built-in floor heating panel to the construction surface of the present invention has been described according to one embodiment and its modifications. However, the present invention is not limited to this. Although the structure has been described as a laminated structure of the back material, the electric heating element and the surface material, a heat insulating material may be provided between the back material and the surface material, and the surface material is also formed by an aggregate of unit plates. Not limited,
Plywood, wood flooring, etc. may be made as a single piece from a suitable member, such as a backing material. Regarding a backing material, a member that can support the surface material on the back surface of the electric heating element irrespective of two or three layers. There is no particular limitation on the electric heating elements, and all the heating elements used for conventional floor heating panels can be used, and their shapes and sizes are arbitrary. It is not necessary for the overall shape of the panel to have a step-like shape as in the embodiment shown in the figure. For example, a square shape, a parallelogram shape, or the like is arbitrary, and the width, length, etc. of each panel are also arbitrary. However, it will be easily understood that the fixing member may be any suitable embodiment as required, such as not only a screw but also a nail.

[0029]

According to the present invention, since the floor heating panels are fixed to the construction surface by fixing members such as screws, the portions are completely concealed. Thus, when a defective part is found in a part of the floor surface of the floor heating structure, only the floor heating panel in that part can be removed and replaced.

In such a case, the protruding portion in the short side direction of each floor heating panel and the protruding storage portion of the floor heating panel adjacent thereto are adhered by an adhesive, whereby shrinkage of the panel at the time of heating is achieved. It is possible to prevent the generation of gaps between panels, and if a layer with a very weak peel strength is provided on the lower surface of the back material, floor noise can be prevented, and the floor heating panel must be removed. It can be done easily.
