Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a floor structure for floor heating and a floor material.

[0002]

[Related technology] There are two types of floor heating: electric heating using hot wires and hot water heating using gas or electricity to circulate hot water through pipes. There is a type in which a floor material such as a flooring in which a veneer is attached to plywood is installed on a floor heating heat source layer to form a heating floor.

For example, in such a heating floor structure, a metal plate is interposed between the floor material and the heat source layer, and the lower surface of the plywood of the floor material is formed with irregularities to form a concave air layer on the metal plate. It is effective to adopt a structure that forms. That is, in this heating floor structure, heat from the heat source layer is transmitted to the metal plate and is effectively dispersed in the in-plane direction of the metal plate due to the high thermal conductivity of the metal plate. Then, the heat dispersed by the metal plate is transmitted to the upper surface of the flooring material through a warm air layer having a small heat capacity. As a result, the floor surface can be quickly and uniformly heated, and the time required for the floor surface to warm can be reduced.

[0004]

By the way, in the above-mentioned floor heating structure, for example, the concave portion on the lower surface of the flooring material, the larger the depth dimension, the faster the heat transfer to the floor surface. However, in such a case, the thickness of the floor material in the concave portion becomes small and thin, and the floor material has no strength. On the other hand, if priority is given to the strength of the flooring material and the depth of the concave portion on the lower surface of the flooring material is reduced, the transfer of heat to the floor surface is slowed down.

[0005] In view of the above problems, the present invention can shorten the time until the floor surface warms by increasing the depth of the concave portion for forming the air layer, and furthermore, the strength is low. It is an object of the present invention to provide a floor heating floor structure and a floor material capable of quickly and uniformly heating a floor without causing any serious problem.

[0006]

The above object is achieved by providing a floor material main body on a heat source layer, the floor material main body having irregularities on the lower surface side, and forming an air layer with the concaves and convexes of the irregularities. This is solved by a floor heating floor structure in which a metal plate is stacked on the upper surface side of the floor material main body.

In this floor structure, the metal plate reinforces the floor material main body from the upper surface side. That is, even if the depth of the concave portion on the lower surface side of the floor material main body is increased, and the thickness of the floor material in the concave portion is reduced and becomes thinner, the metal plate reinforces this portion to increase the strength of the floor. It can be enough. As a result, it is possible to increase the depth of the concave portion for forming the air layer and shorten the time until the floor surface warms up, but still cause a strength problem due to such air layer formation. Nor. Moreover, since the metal plate is used as described above, in floor heating, the heat transmitted from the heat source through the air layer is effectively dispersed in the in-plane direction by the metal plate, and thus the heat dispersed by the metal plate is dissipated. Since it is transmitted to the floor, the floor can be quickly and uniformly heated.

Further, in the above invention, the air layer is formed by the floor material main body having unevenness on the lower surface side. However, the air layer is not limited to such a planar floor material body, but may be a dot-like or linear shape. A spacer may be interposed in a dispersed state between the heat source layer and the metal plate to form an air layer,
Further, an air layer may be formed by interposing a perforated plate provided with dispersed through holes for forming an air layer between the heat source layer and the metal plate as a floor material main body. In short, it is only necessary that the floor structure is such that the metal plate is stacked on the heat source layer via the air layer. Even in this case, the metal plate closes the cavity of the air layer from above to reinforce the floor, and does not cause a strength problem due to the formation of the air layer. Moreover, in the case of a spacer or a perforated plate, the depth of the cavity can be as large as possible, and the time until the floor surface warms can be further shortened.

In each of the above floor structures, when a finishing plate is installed on a metal plate, the finishing plate is reinforced by the metal plate, and the finished plate has strength even if it is thinned.
By making the finishing board thinner, the time until the floor surface warms can be further shortened.

[0010] Further, a floor material main body having an uneven surface on the lower surface side and forming an air layer with the concave portion of the unevenness, and a metal plate which is overlaid on the upper surface of the floor material body and integrated with the floor material main body. In the floor heating floor material provided, or an air layer forming member that forms an air layer on the lower surface of a metal plate, the floor heating floor material provided integrally with the metal plate has the floor heating member. The floor heating floor structure including the air layer and the metal plate can be formed by simply installing the material, and the floor heating floor structure including the air layer and the metal plate can be easily constructed. .

In this case, when the finishing plate is installed on the metal plate and the finishing plate is integrated with the metal plate, the finishing plate can also be installed at the same time by installing the floor material. Construction can be performed more easily.

[0012]

Next, embodiments of the present invention will be described with reference to the drawings.

In the floor structure for floor heating of the embodiment shown in FIG. 1, 1 is a heat source layer, and 2 is a floor material. The heat source layer 1 is made of a hot water type having a pipe 3 for circulating hot water, and the floor material 2 is for flooring, and a floor material main body 4 as an air layer forming member, a metal plate 5, And a finishing plate 7.

The floor material body 4 is made of plywood or the like, and its total thickness is not particularly limited.
It is about 2 mm. The lower surface side of the floor material main body 4 is uneven, the air layers 10 are formed by the recesses 8..., And the floor material main body 4 is supported from below by the protrusions 9.

The recesses 8 for forming the air layer 10 are as follows.
Is preferably formed as deeply as possible from the lower surface to the upper surface of the base 6 and as wide and dense as possible in the plane direction in order to quickly transfer heat to the upper surface of the flooring 2. As described later, the metal plate 5 is superposed on the upper surface side of the floor material main body 4, and the metal plate 5 reinforces the corresponding portions of the concave portions 8 of the floor material main body 4. The dimensions can be set quite large.

The metal plate 5 is made of, for example, a copper plate or an aluminum plate having good thermal conductivity, is superposed on the upper surface side of the floor material main body 4, and is joined and integrated with the floor material main body 4 with an adhesive or the like.
Note that the floor material main body 4 and the metal plate 5 may be merely superposed without being joined and integrated.
If the thickness of the metal plate 5 is too small, the heat source layer 1
Not only can not sufficiently disperse the heat from the floor in the in-plane direction, but also cannot sufficiently reinforce the floor material body 4 provided with the concave portions 8... The above effect is saturated and wasteful, and may cause adverse effects such as increasing the weight of the flooring material 2.
It is sufficient if the dimensions are set appropriately in consideration of the above. Specifically, for example, in the range of 0.5 to 5 mm, particularly the lower limit is about 1 mm, and the upper limit is about 2 mm or 3 m.
m. It goes without saying that the present invention is not limited to these numerical ranges.

A finishing plate 7 is provided on the upper surface of the metal plate 5.
Are laminated and bonded and integrated with the metal plate 5 with an adhesive or the like. Note that the metal plate 5 and the finished plate 7 may be merely superposed without being joined and integrated. The thickness of the finishing plate 7 is thin because the finishing plate 7 is supported and reinforced by the metal plate 5 from the lower surface side, and heat is dispersed in the plane direction by the metal plate 5. May be. By making it thin, the heat from the metal plate 5 can be quickly transmitted to the floor 11 and the time until the floor 11 warms can be reduced.

In the present embodiment, the heating floor is the floor material 2 described above.
Is provided on the floor heating heat source layer 1.
Note that a combination of the heat source layer 1 and the floor material 2 in advance may be used as the floor material, and the floor material may be installed on the site to form the floor to be searched.

In the above floor structure, the heat from the heat source layer 1 is
The heat is quickly transmitted to the metal plate 5 through the warm air layer 10 having a small heat capacity of the floor material body 4, and is effectively dispersed in the in-plane direction of the metal plate 5 by the high thermal conductivity of the metal plate 5, and thus dispersed. Heat is transmitted to the floor 11 through the finishing plate 7. Therefore, the time until the floor surface 11 warms can be shortened, and the floor surface 11 can be quickly and uniformly heated. In particular, since the finishing plate 7 is reinforced by the metal plate 5, its thickness dimension may be thin, and the time until the floor surface 11 warms can be shortened. Since the concave portions 8 of the floor material main body 4 are reinforced by the metal plate 5 stacked on the upper surface of the floor material main body 4, the depth dimension of the concave portions 8 on the lower surface side of the floor material main body 4 is increased. The depth of the recesses 8 for forming the air layer 10 can be increased, and the time required for the floor surface 11 to warm can be further shortened.

Although the embodiment of the present invention has been described above, the present invention is not limited to this, and various modifications can be made without departing from the spirit of the invention. For example, in the above-described embodiment, a case where the present invention is applied to a hot-water floor heating structure in which hot water is passed through a pipe is shown.
It may be used for other types. Further, the flooring material of the present invention may be configured in advance with a heat source such as a hot water pipe or a hot wire. Further, as the metal constituting the metal plate, various types may be used,
The flooring material may be various flooring materials in addition to the flooring. When the floor material main body 4 has irregularities on the lower surface side, there is no particular limitation on the form of the irregularities to be formed. Various types of irregularities may be used, such as a linear concave part with the remaining part being convex. Further, a metal plate may be additionally provided on the lower surface side of the floor material main body and the air layer, and in this case, the floor material main body, the air layer and the metal plate on the lower surface side are used in manufacturing and construction. It may be joined in advance or afterwards to be integrated, or may not be joined.
