Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tatami mat for floor heating, wherein the tatami mat is laid on a planar heating element constituting a floor heating structure of a building. The present invention relates to a tatami floor heating structure constructed by laying tatami mats.

[0002]

2. Description of the Related Art Conventionally, a tatami floor heating structure is disclosed in
-294201. In this tatami floor heating structure, a large number of metal members with excellent thermal conductivity are embedded in the tatami mat laid on the sheet heating element so as to expose the back side, and the heat of the sheet heating element is efficiently reduced to near the surface of the tatami. It is configured to conduct well.

In Japanese Utility Model Publication No. 7-32737,
A tatami mat laid on a floor heating panel, in which a plurality of processed sheets such as straw materials are stacked on a rigid core sheet made of a band-like plate material to form a tatami floor, and a tatami mat is placed on the upper surface of the tatami floor. Are shown.

[0004]

By the way, as in the tatami heating structure described in the above-mentioned Japanese Patent Application Laid-Open No. 6-294201, a special structure in which a large number of metal members for heat conduction are embedded is used. Then, not only is the cost of tatami expensive, but it has not become widespread in terms of construction and maintenance. Also, as a structural problem,
Since the temperature of the portion of the metal member embedded in the tatami becomes higher than that of the other portions and the temperature of the tatami surface becomes uneven, a suitable heating effect cannot be expected.

In the tatami described in Japanese Utility Model Publication No. Hei 7-32737, the thermal conductivity of the material constituting the tatami floor is not necessarily high. Is supplemented. For this reason, this conventional tatami mat is not only impaired in the important cushioning property which is an essential characteristic of the tatami mat, but also inferior in heat insulation.

Therefore, the present invention provides a floor heating tatami by stacking a tatami floor on the tatami floor with the core layer and the buffer layer having good thermal conductivity and a tatami mat layer laminated on the tatami floor via the buffer layer. By improving the thermal conductivity of the tatami floor and improving the heat transfer efficiency, the tatami floor can be made thinner even if it is made thinner. It is an object of the present invention to provide a tatami mat and a tatami floor heating structure using the tatami mat.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 shows an example of a tatami floor heating structure according to the present invention. FIG. 1 is an exploded perspective view thereof, and FIG. 2 is a sectional view of a tatami floor heating tatami.

In FIG. 1, 1 is a tatami mat for floor heating, 2 is a sheet heating element, and 3 is a heat insulating material made of expanded polystyrene.
The tatami floor heating structure according to the present invention is configured by laying a heat insulating material 3 below the sheet heating element 2 and laying the floor heating tatami 1 on the sheet heating element 2.

As shown in detail in FIG. 2, the tatami floor for floor heating 1 has a tatami floor 4 having a core structure 5 and a buffer layer 6 having good thermal conductivity. The tatami mat 7 is stacked with the buffer layer 6 interposed therebetween. The core layer 5 of the tatami floor 4 is a panel made of a synthetic resin, the buffer layer 6 is formed by laminating a non-woven fabric 9 on the upper surface of a paperboard 8, and the tatami mat 7 is a woven fabric made of a synthetic resin. The tatami table 7 may be a woven fabric such as rush.
In the illustrated embodiment, the nonwoven fabric 10 is also laminated on the lower surface of the core layer 5.

The synthetic resin panel constituting the core layer 5 of the tatami floor can be formed by pressing a compressed magnetic tape for recording or video discarded and discarding it to form a panel. The use of this material not only allows recycling of waste materials, but also can constitute the core layer 5 having excellent heat conductivity and appropriate buffering properties.

That is, in the case where the core layer 5 is formed of a crushed material of a magnetic tape, the hardened crushed materials are bridged with each other, and a large number of small closed cells are formed therebetween. For this reason, by using the one having this configuration, it is possible to perform efficient tatami floor heating that is excellent in heat retention, despite having good thermal conductivity from the planar heating element 2. .

The total thickness of the tatami floor 1 and the tatami table 7 of the tatami for heating 1 is suitably 8 to 30 mm, of which a specific thickness in the range of 16 to 20 mm is preferred. Is preferred. In other words, the tatami for floor heating 1 preferably has a higher heat conduction efficiency when the thickness thereof is thinner. However, if the tatami mat 1 is within the above range, it is possible to maintain a satisfactory heat conduction efficiency and also satisfy load resistance. it can. In particular, as in the illustrated embodiment, the tatami floor 4 has a multi-layer structure, so that even if the floor heating tatami 1 has a smaller thickness, the intended load resistance can be provided.

The thickness of the core layer 5 is 3 times the thickness of the entire tatami mat.
0 to 70%. Since the core layer 5 has a layer structure having good thermal conductivity as described above, it is not preferable that the thickness of the core layer 5 is less than 30% of the entire tatami mat because the thermal conductivity is poor. However, the thickness of the core layer 5 is 70% of the thickness of the entire tatami mat.
%, The thickness of the core layer 5 is 30 to 7 times the thickness of the entire tatami mat.
Preferably it is 0%.

In the tatami floor for floor heating 1 according to the present invention, the upper surface of the tatami floor 4 forms a buffer layer 6 having a laminated structure of a paperboard 8 and a nonwoven fabric 9, which is interposed between the tatami table 7 and the tatami table 7. The nonwoven fabric 10 on the lower surface of the core layer 5 also contributes to improving the overall buffering effect.

The heat insulating material 3 is preferably a foamed polystyrene panel having a thickness of 25 to 30 mm, but may be made of another foamed resin. The thicker the heat insulating material 3, the better the heat insulating property. However, if the heat insulating material 3 is too thick, the load resistance is impaired. Therefore, in the case of a foamed polystyrene panel, the thickness within the above range is appropriate.

[0022]

According to the present invention, a tatami floor has a layer structure of a core layer and a buffer layer having good heat conductivity, and a tatami mat is laminated on the tatami floor via the buffer layer to form a tatami mat for floor heating. With this structure, the thermal conductivity of the tatami floor is improved, and even if the tatami floor is made thinner in order to further increase the heat transfer efficiency, the floor is excellent in load resistance and excellent in feel due to the buffer effect. A tatami mat for heating and a tatami floor heating structure using the tatami mat can be provided.
