  However, in the conventional floor heating panel 1 as described above, when plywood is used as the flooring material 2 as illustrated in FIG. 6, the plate thickness differs between the portion where the storage recess 21 is formed and the surrounding portion. Since the balance is lost, the plywood is warped, and it may be difficult to maintain the quality of the flooring 2.

  On the other hand, in order to suppress the warpage of the plywood, as illustrated in FIG. 7, a bar-like plywood having a normal layer configuration is provided on the back side of the plate-like plywood whose layer configuration is denser than usual. It is also conceivable to form the storage recess 21 between them.

  However, even if the warpage of the plywood can be suppressed, it is necessary to prepare two types of plywood having different layer configurations, and thus the number of plywood varieties increases.

  Moreover, although it is common to both the said structures, since the surrounding site | part of the storage recess 21 turns into a non-heating site | part which does not have the heat generating body 3 so that it may become clear also from FIG.

  Furthermore, since the heat insulating material 4 positioned below the heating element 3 requires means for holding it in the storage recess 21 opened downward, the structure of the flooring 2 and the storage recess 21 is provided. To be complicated.

  Therefore, in view of the circumstances as described above, the present invention effectively suppresses the warpage of the flooring made of plywood, and can reduce the non-heating part as much as possible, and further simplifies the holding structure of the heat insulating material. An object is to provide a floor heating panel.

  In order to solve the above-mentioned problems, the present invention firstly, a surface layer plywood having a uniform plate thickness in the entire region and a base material plywood provided with a storage recess are bonded to each other; a surface layer plywood; A heating element provided above the storage recess of the base layer plywood between the base layer plywood, a soaking material provided to cover a wider area than the heating element between the surface layer plywood and the base layer plywood, and It has the heat insulating material provided in the downward position of the heat generating body within the storage recess.

  Second, it further includes a reinforcing plate that is provided over the longitudinal direction at the center position in the width direction of the heat insulating material in the housing recess of the base layer plywood and reinforces the surface layer plywood from below against the load from above. It is characterized by being.

  Thirdly, the reinforcing plate has rigidity to reinforce the surface layer plywood, and at least its surface has a softer material than the surface layer plywood.

  According to the first aspect of the invention, first, the flooring is made of a two-layer structure of a surface plywood having a uniform plate thickness without a storage recess and a base layer plywood having a storage recess, whereby warpage of the surface plywood occurs. Floor materials that are effectively suppressed and maintain high quality are realized.

  In addition, between the surface plywood and the base layer plywood, a heating element is provided above the storage recess of the base layer plywood, and a heat equalizing plate is provided on the upper side so as to cover a wider area than the heating element. The heat from can be transferred to a wider range, and the non-heating part can be reduced.

  And as for the heat insulating material, it is only necessary to provide in the storage recess opened upward in the base layer plywood, so compared with the case where it is provided in the storage recess opened downward on the back side of the floor material as in the conventional case, A complicated holding structure and complicated processing therefor are not required, and the configuration and construction relating to the heat insulating material can be simplified.

  Therefore, the floor heating panel which implement | achieved the curvature prevention of a flooring, reduction of a non-heating part, and simplification of a heat insulation structure is provided.

  According to the second invention, the same effects as those of the first invention can be obtained, and when a load is applied to the surface plywood from above due to the presence of the reinforcing plate as described above, the surface plywood together with the load is applied. Therefore, the occurrence of deflection of the surface plywood can be effectively suppressed.

  According to the third aspect of the invention, the same effect as the second aspect of the invention can be obtained, and the reinforcing plate has a rigidity that can support and reinforce the surface plywood as described above, By having at least the surface of the material softer than the surface layer plywood, when a load is applied to the surface layer plywood from above, it is possible to prevent the heating element located below the surface layer plywood from being damaged.

  1 and 2 each show an embodiment of the present invention.

  In the floor heating panel 1 in the present embodiment, first, the flooring 2 is configured such that a rectangular surface layer plywood 2a and a rectangular base layer plywood 2b are bonded to each other up and down, and the surface layer plywood 2a includes: There is no storage recess 21 in the conventional floor heating panel 1, and the plate thickness is uniform throughout the entire area. On the other hand, the base layer plywood 2b is provided with a storage recess 21 opened upward in which a heat insulating material 4 to be described later is stored, leaving a wiring space 22 in which a wiring tool such as the connector 7 is stored.

  Between the surface layer plywood 2a and the base layer plywood 2b, a heating element 3 and a soaking material 5 are provided. The heating element 3 is a rectangular planar type, and the housing recess of the base layer plywood 2b. In the present embodiment, the soaking material 5 has a planar dimension covering almost the entire region of the base layer plywood 2b so as to cover a wider area than the heating element 3, Located above.

  And the heat insulating material 4 located under the heat generating body 3 is provided in the storage recess 21 of the base layer plywood 2b.

  Therefore, the floor heating panel 1 is based on the floor material 2 composed of upper and lower two layers of the surface plywood 2a having a uniform thickness without the storage recess 21 and the base layer plywood 2b having the storage recess 21, as described above. The soaking material 5, the heating element 3, and the heat insulating material 4 are accommodated, and the floor material 2 is prevented from warping, the non-heating part is reduced, and the heat insulating structure is simplified.

  By the way, in the floor heating panel 1 as described above, when a load is applied to the surface plywood 2a of the flooring 2 from above, the low-rigidity heating element 3 and the heat insulating material 4 are housed in a wide range below. Therefore, the surface layer plywood 2a cannot be sufficiently supported as it is, and the surface layer plywood 2a may bend. Therefore, in the housing recess 21 of the base layer plywood 2b, the reinforcing material 6 is provided in the longitudinal direction at the center position in the width direction of the rectangular heat insulating material 4, thereby effectively generating the deflection of the surface layer plywood 2a. Can be suppressed.

  More specifically, in the embodiment of FIGS. 1 and 2, as illustrated in FIG. 3, the heat insulating material 4 vertically divided into two in the middle in the storage recess 21 and the bar plate fitted therebetween. The reinforcing material 6 is stored. Thereby, since the reinforcing material 6 passes in the storage recess 21 of the base layer plywood 2b, the floor heating panel 1 that can receive and support the surface layer plywood 2a from below with respect to a load from above, and is less likely to bend. It is realized.

  In addition, the reinforcing member 6 may also be damaged by the load from above. For example, the reinforcing member 6 has rigidity to reinforce the surface plywood 2a. It is preferable that at least the surface thereof has a material softer than the surface plywood 2a. According to this, the damage to the heat generating body 3 located between the surface layer plywood 2a and the reinforcing material 6 can be effectively prevented.

  FIG. 4 shows another embodiment of the present invention as described above. The wiring tool such as the connector 7 and its wiring space 22 are provided at the left and right longitudinal ends of the base layer plywood 2b. In order to avoid this, a storage recess 21 is formed in almost the entire region, in which the heat insulating material 4 and the reinforcing material 6 are stored, and the heating element 3 and the heat equalizing material 5 are provided above the storage heating panel 1. It has become.
