Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat storage basic structure of a building, and is intended to eliminate a limitation on a floor interior finish of a direct gain type solar house.

[0002]

2. Description of the Related Art Since the oil crisis, due to the growing momentum to effectively use natural energy instead of oil and gas, and the recent growing interest in the global environment, petroleum has become a cause of global warming in the field of construction. It is conceivable to use irradiation energy from the sun instead of heating or cooling a building using gas as an energy source, and it is being put into practical use as a solar house.

The structure of a conventional solar house is, for example, shown in FIG.
As shown in 1-5, those which are certified by the Energy Conservation Agency (IBEC) can be roughly classified into the following five systems.

[0004] -1: Direct gain method -2: Combination method of air heat collection and heat storage -3: Combination method of air collection and greenhouse and heat storage -4: Combination method of wall heat collection and air circulation -5: Solar power generation method Of the solar home systems, the most popular one is that the structure is relatively simple and can be constructed at low cost.
This is the direct gain method shown in FIG.

In the direct gain method, heat of sunlight is taken into a room through a window or the like which is an opening of a building in winter and collected in a heat storage unit on the floor to be used as a heat source for heating. Opening windows, etc., which are openings in the building, take in cool air at night into the room, collect this cool air in the heat storage on the floor and release it during the day to cool the inside of the building. There is an advantage that natural energy such as sunlight can be used.

In this direct gain type house, as shown schematically in FIG. 7, a cloth foundation concrete 3 is erected via a waste concrete 2 on a split rubble stone 1, and the surface of the outdoor side A is covered with basic insulation. Covered with material 4.

[0007] In order to perform the heat storage of the direct gain system, on the indoor side B of the cloth foundation concrete 3, the earth concrete 5 is integrally connected to the upper end of the cloth foundation concrete 3 via the split stone 1. The soil concrete 5 functions as a heat storage body under the floor.

Further, on the cloth foundation concrete 3,
A frame 7 is attached via a base 6, and an outer wall heat insulating material 9 is disposed on the outdoor side A of the frame 7 excluding the window portion 8 and is fixed via a ventilation shell 10. An outer wall material 11 is attached to the outside of the vehicle, and a drainer 12 is provided between the lower end surface of the outer wall material 11 and the ventilation shell 10. Finishing material 1
4 is attached, and a skirting board 15 is attached to the lower end corner.

Further, a floor interior material 16 is attached to the upper surface of the indoor side B of the concrete slab 5 which also functions as a heat storage body.

A dog running concrete 17 is cast on the ground surface C on the outdoor side A of the basic heat insulating material 4 of the cloth base concrete 3 via the split stone 1.

In the case of such a direct gain system,
In order to make the heat storage body composed of the clay concrete 5 easily absorb the thermal energy of the sun from the window 8, the clay concrete 5 as the heat storage body is exposed to the room or the floor covering the indoor surface of the clay concrete 5 is used. It is necessary to make the surface interior material 16 thin and have a high thermal conductivity.

[0012]

However, since the heat storage body is on the floor of the building and concrete or stone is used as the material, the interior material and finish of the floor are extremely limited for residents. When using ordinary floor interior materials such as Japanese-style tatami flooring, Western-style flooring and carpet, for example, the thermal conductivity is relatively small, so the heat storage efficiency of the heat storage unit is reduced, and the direct gain method should be used. Can only be used as floor material such as linoleum, etc., and can only be used as a concrete finish or stone polishing as a floor finish. There is a problem of giving the impression that the floor is cold and hard.

[0013] Further, in the case where cold air is to be stored in summer, it is necessary to open the window at night and directly take in outside air into the room, which causes a problem in crime prevention.

The present invention has been made in view of the above-mentioned problems of the prior art, and it is possible to freely select a floor interior material and a floor finish even in the case of a direct gain system in which a heat storage body is provided in a building. It is intended to provide a thermal storage base structure for a building that is capable and has no security problems.

[0015]

The choice of surface interior materials and the like becomes free, and there is no security problem.

According to a second aspect of the present invention, in addition to the structure of the first aspect, the heat storage portion also serves as soil concrete and the heat receiving portion also serves as dog running concrete. It is characterized by having made it.

According to the heat storage basic structure of this building, the heat storage portion is also used as the concrete between the soil and the heat receiving portion is also used as the dog running concrete, and a part of the dog running concrete which is the heat receiving portion is directly put on the cloth. It is only necessary to remove the heat insulating material so that it comes into contact with the foundation, and it is possible to realize a direct gain type heat storage with a simpler structure without limiting the selection of floor interior materials etc. .

Further, the heat storage basic structure of a building according to claim 3 of the present invention, in addition to the structure according to claim 1 or 2, further includes a lower side of the heat storage section, a lower side of the heat receiving section, and the cloth. A heat insulating material is provided on at least one of the indoor surface other than the contact part of the heat storage part of the foundation.
