Description

The present invention relates to a heat storage floor structure in which a heat storage panel is combined with a heat storage body.

BACKGROUND ART Conventionally, as a floor heating structure for heating a floor surface inside a building, for example, as shown in Patent Document 1, a heat-damping vibration damping board and a synthetic resin foam sheet are placed in this order on a base board. A heating floor structure is known in which a plurality of sheet heating elements are arranged on a synthetic resin foam sheet, and a flooring material is provided on the upper surface of the sheet heating element.

JP, 2002-106159, A

In the above Patent Document 1, a synthetic resin foam sheet is installed between the heating element and the vibration damping and sound insulating plate. However, since the structure mainly aims at the vibration damping/insulating effect, the synthetic resin foam sheet has a small thermal conductivity, and it is difficult to sufficiently transfer the heat of the heating element to the vibration damping/insulating plate. Similarly, since the synthetic resin foam sheet is interposed between the heating element and the vibration damping and noise insulating plate, the heat accumulated in the vibration damping and noise insulating plate is hard to be transmitted to the surface floor material. That is, there is a problem that the heat storage performance of the vibration damping and sound insulating plate is not sufficiently exhibited.

Further, since the synthetic resin foam sheet is a soft material, the flooring material is more likely to be unsteady due to a construction defect as compared with the case where a hard material is used. In addition, the sinking of the floor material during walking may cause a pedestrian to feel uncomfortable while walking.

The present invention has been made in view of such various points, and an object thereof is a heat storage floor structure in which a heat storage body is combined with a floor material having a heat generating portion, in which heat transfer efficiency from the floor material to the heat storage body is high and workability is high. It is to prevent pedestrians from feeling uncomfortable while walking.

In order to achieve the above-mentioned object, in the present invention, a heat storage material on a floor substrate, a wooden plate material, and a plate-shaped floor material in which the heat generating portion is housed, are constructed in a laminated state in the order described. .. Thereby, the heat of the heat generating portion of the floor material is easily transferred to the heat storage body.

Specifically, in the latent heat storage floor structure according to the first aspect of the present invention, a heat storage material is placed on a floor substrate, and a wood board material and a plate-shaped floor material that accommodates a heat generating portion are provided on the heat storage material. It is characterized in that they are constructed in the state in which they are stacked in the stated order.

In the present invention, the term "heat generation" includes not only warm heat but also cold heat.

In the first aspect of the invention, the heat storage body, the wooden board material, and the floor material are installed in a laminated state. Here, the wood board has a larger thermal conductivity than a synthetic resin foam sheet or the like used in a conventional heat storage floor structure. Therefore, the heat of the heat generating portion of the floor material is more likely to be transferred to the heat storage body as compared with the conventional technique. Similarly, the heat released from the heat storage body is also easily transmitted to the floor material through the wooden board material. That is, since the heat transfer efficiency between the floor material (heat generating part) and the heat storage body is increased, the heat storage performance of the heat storage body can be sufficiently exhibited. Therefore, it is possible to enhance the effect of sustaining the heat or cold of the floor material, that is, the floor surface.

In addition, since a plate-shaped floor covering the heat generating part is installed on the wooden board, even if the size of the heat storage body changes due to heat, the influence of the size change of the heat storage body on the floor material Can be prevented. That is, it is not necessary to carry out the construction in consideration of the influence on the floor material, and the workability is excellent.

Further, the wooden board material has a sufficiently high hardness as compared with a synthetic resin foam sheet or the like, and according to this aspect, it is possible to prevent a pedestrian from feeling uncomfortable while walking.

A second aspect of the present invention is an integrated floor material, wherein the floor material is a wooden base material having a groove, and a pipe serving as the heat generating portion in which hot water or cold water flows is integrally housed in the groove. It is characterized by

In the second aspect of the invention, when the heat generating portion is a pipe integrally housed in the wood base material, the heat storage property of the heat storage body and the workability of the heat storage floor structure can be enhanced.

A third invention is characterized in that the wood board has a thickness of 2 mm or more and 12 mm or less and a thermal conductivity of 0.1 [W/mK] or more.

In the third invention, as in the first and second inventions, the heat storage performance of the heat storage body can be sufficiently exhibited, and the workability of the heat storage floor structure can be enhanced.

If the thickness of the wooden board is less than 2 mm, it may not be rigid and may be difficult to construct. On the other hand, if it is more than 12 mm, the thermal resistance may increase and the heat may not be sufficiently stored in the lower heat storage body. It is set to the above and 12 mm or less. If the thermal conductivity is less than 0.1 [W/mK], the thermal resistance becomes large, and heat may not be sufficiently stored in the lower heat storage body. Therefore, the thermal conductivity is set to 0.1 [W/mK] or more. ing.

As described above, according to the present invention, the heat storage body, the wooden board and the floor material are constructed so as to be in a laminated state, so that the heat transfer efficiency between the floor material and the heat storage body is increased, and the heat storage floor structure is provided. The workability of can be improved.

FIG. 1 is a sectional view of a heat storage floor structure according to an embodiment of the present invention.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The description of the embodiments below is merely exemplary in nature, and is not intended to limit the present invention, its application, or its use.

FIG. 1 shows a heat storage floor structure according to an embodiment of the present invention.

As shown in FIG. 1, a plurality of heat storage mats 2, 2,... Made of a heat storage material are laid and constructed on a floor base 1 on the floor of the room inside the building. The heat storage mat 2 has, for example, a rectangular plate shape or a sheet shape having a thickness of 3 mm or more, and may have a thickness of 15 mm or more, for example. For the heat storage mat 2, a material having a large sensible heat capacity, such as a synthetic rubber-based material or an asphalt-based material, is preferably used. Alternatively, a material having a large latent heat capacity containing paraffin, an inorganic salt, and/or an olefin is used. Although not shown, the heat storage mat 2 is constructed in a state of being fixed to the floor base 1 by a fastener such as a staple. Although not shown, each heat storage mat 2 may be laid with a space of several mm between adjacent heat storage mats 2.

On the heat storage mat 2 laid on the floor base 1, a wood board 3 and a concave groove 42 on the lower surface are integrally formed with the hot water pipe 5 accommodated in the concave groove 42. The underfloor heating panel 4 and the floor heating panel 4 are installed in the order in which they are stacked.

As the wooden board 3, for example, a board having a thickness of 2 to 12 mm and a thermal conductivity of 0.1 [W/mK] or more is preferably used. For example, if the thickness of the wooden board material 3 is thinner than 2 mm, the rigidity required for construction may not be obtained, and the workability may deteriorate. On the other hand, when the thickness of the wooden board material 3 is thicker than 12 mm, the thermal resistance of the wooden board material 3 becomes large, the heat of the hot water pipe 5 becomes difficult to be transferred to the heat storage mat 2, and the heat storage performance of the heat storage mat 2 is sufficiently exerted. It may disappear. Further, for example, when the thermal conductivity of the wooden board material 3 is less than 0.1 [W/mK], the thermal resistance of the wooden board material 3 becomes large, and the heat of the hot water pipe 5 is less likely to be transferred to the heat storage mat 2 and the heat storage mat The heat storage performance of No. 2 may not be fully exhibited. As the wood board material 3, for example, plywood, MDF (medium density fiber board), particle board, OSB (oriented strand board), hard board and the like are used.

The floor heating panel 4 has, for example, a long plate-shaped panel body 41 made of plywood, veneer, MDF or the like having a thickness of about 10 mm, and its back surface (lower surface) has a short side direction and a long side direction. A concave groove 42 that meanders and extends so as to have portions parallel to each other is formed. The hot water pipe 5 is housed in the groove 42 via a heat releasing material such as aluminum foil, and hot water flows in the hot water pipe 5. In addition, a male nut 43 formed of a ridge is formed on one short side of the panel body 41, and a female nut 44 formed of a groove that can be fitted with the male nut 43 is formed on the other short side. ing.

When constructing the heat storage floor structure, after applying the floor cooling and heating adhesive 6 on the wooden board 3 and applying the adhesive to the male 43 and female 44 of the panel body 41 of the floor heating panel 4. , The male seed 43 and the female seed 44 are fitted to the male seed 43 and the female seed 44 of the floor heating panel 4 adjacent to each other, and then the floor heating panel 4 is placed on the wooden board 3 and the adhesive is applied. Let it solidify. Furthermore, after that, the floor heating panel 4 may be fixed to the wooden board 3 by using flooring staples or the like. For example, a surface material such as a decorative veneer may be attached to the surface of the panel body.

As described above, according to the present embodiment, a plurality of heat storage mats 2, 2,... Are spread over the floor base 1, and the construction is performed. On the heat storage mat 2, the wood board 3 and the lower surface The floor heating panel 4 of the integrated type in which the hot water pipe 5 is integrally housed in the groove 42 is constructed in a state of being stacked in the order described. Here, since the wood board 3 has a higher thermal conductivity than the conventional technique (for example, a synthetic resin foam sheet), the heat of the hot water pipe 5 of the floor heating panel 4 is easily transferred to the heat storage mat 2. Similarly, the heat released from the heat storage mat 2 is also easily transferred to the floor heating panel 4 via the wooden board 3. In this way, since the heat transfer efficiency between the floor heating panel 4 and the heat storage mat 2 is increased, the heat storage performance of the heat storage mat 2 can be sufficiently exerted, and the effect of sustaining the heat of the floor heating panel 4 is enhanced. be able to.

Further, in the process of heat storage or heat dissipation, even when the dimensions of the heat storage mat 2 change due to temperature change, the wood plate material 3 is interposed between the heat storage mat 2 and the floor heating panel 4, so It is possible to prevent the floor heating panel 4 from being affected by the dimensional change of the mat 2. That is, it is not necessary to carry out the construction in consideration of the influence on the floor heating panel 4, and the construction is excellent.

Furthermore, since the wooden board 3 has a sufficiently high hardness as compared with the synthetic resin foam sheet or the like according to the related art, it is possible to prevent a pedestrian from feeling uncomfortable due to the depression of the floor material during walking.

(Other embodiments)
The above embodiment is a case of a heat storage floor structure in which floor heating is performed by the floor heating panel 4 having the hot water pipe 5, but floor cooling may be performed by a floor cooling panel having a cold water pipe for flowing cold water. It is also possible to switch between floor heating and floor cooling by an integrated floor cooling and heating panel having a pipe for flowing hot water or cold water. Even in this case, the same effect as that of the above embodiment can be obtained. That is, it is possible to enhance the cooling effect of the floor cooling panel or the heating effect of the floor heating/cooling panel, which is excellent in workability and makes it possible for a pedestrian to walk without feeling uncomfortable.

Further, when performing floor heating, an electric heater may be used instead of the hot water pipe 5.

Since the present invention is constructed such that the heat storage body, the wood board, and the floor heating panel accommodating the heat-generating part are constructed in a laminated state in that order on the floor substrate, the heat transfer efficiency is high and the construction efficiency is excellent. , Very useful.
