Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a soundproof type heat storage floor heating system used in an apartment house or the like.

[0002]

2. Description of the Related Art First, heat storage floor heating is head cold foot heat,
Secondly, it has become widely used due to radiant heating, thirdly clean indoor air, and thirdly, low running cost due to heat storage by using late-night power.

However, in the case of wooden surface finishing materials, which have been booming in recent years, since they do not take into account the soundproofness against the impact sound to the downstairs caused by the walking of people or the falling of objects, they are used for apartment houses such as condominiums. I couldn't. Moreover, in the conventional heat storage floor heating device shown in FIG.
Since it was formed by the joist construction method, joist 8, heat storage material 2,
The heater 3, the heat insulating material 4, and the surface finishing material 1 had to be separately installed, and the construction was complicated. 9 is an air layer.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above drawbacks, and an object of the present invention is to provide a heat storage floor heating device with a soundproofing function so that it can be easily installed.

[0005]

The soundproof type heat storage floor heating system of the present invention is a package 5 in which a heat storage material 2, a heating element 3, and a heat insulating material 4 are laminated inside the surface finishing material 1 in this order from the top. Is provided
Underneath it is an elastic base material 6 made of rubber foam or nonwoven fabric.
Are laminated.

As the surface finish material 1, a carpet, a wood board material, or a material in which an elastic material or a heat insulating material is laminated and integrated under a wood board material is used.

[0007]

[Operation] In the case of a light impact sound such as walking of a person or dropping of an object, it is proportional to the maximum impact force applied to the floor material, and the greater the impact absorbing capacity of the floor material, the greater the ability to reduce the floor impact sound. . The maximum impact force F is given by F = C (1 + μ) K ^1/3 (1) C: constant determined by impact source μ: coefficient of restitution K: spring constant per unit area of floor material.

The conventional heat storage floor heating shown in FIG. 5 has a rigid structure due to the joist construction method, that is, (1)
The spring constant K per unit area of the floor material in the formula is large (for example, in the case of a wooden joist 45 mm square, K = 1.3 × 1)
0 ¹¹ N / m · m ² ), the impact force applied is transmitted to the slab as it is, so the noise downstairs becomes loud.

In the heat storage floor heating according to the present invention, a joist construction method is not used, and a package in which a heat storage material, a heater and a heat insulating material are installed is provided below the surface finishing material, and a rubber foam or a non-woven fabric is provided below the envelope. An elastic base material consisting of

Thus, the spring per unit area of the elastic base material
The constant K is the joist (K = 1.3 × 10 ¹¹N / m ・ m²)
If it is made smaller, the maximum impact force F becomes smaller than that of equation (1).
The floor impact noise can be reduced.

In the present invention, since the elastic base material such as the rubber foam or the non-woven fabric is used, the spring constant K per unit area is 10 ⁹ N / m · m ² or less, which is smaller than the joist and the floor impact noise. Can be reduced.

Further, according to the present invention, since a laminate of a heat storage material, a heating element and a heat insulating material is installed in an envelope made of plywood or the like, it becomes an integrated type, and the heat storage material and the heating element are the same as in the conventional heat storage floor heating. Compared with complicated construction such as installing heat insulation materials individually, simple construction is possible.
