Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a high insulation construction method for buildings such as houses. More specifically, the present invention relates to a high thermal insulation construction method that prevents heat dissipation from the floor of a building as much as possible, and recovers the dissipated heat with high thermal efficiency and energy saving.

Conventionally, the construction method shown in Figure IX1, in which earth is embanked on the inside of the foundation, split stones or cut gravel are spread over the embankment, earthen floor concrete is laid on top of that, and a floor finish is constructed on top of it, is known. There is.

However, with this construction method, the heat inside the room is easily dissipated through the floor surface, and the dissipated heat passes through the concrete floor and the cracked stone layer, and is then used to heat the ground. Therefore, the amount of heat radiated through the floor was quite large.

Furthermore, in cold regions such as Tohoku and Hokkaido, a heat insulation method is often practiced in which heat insulating material is installed on the walls and floors of buildings such as houses, as shown in FIG. However, with this method, the temperature of the air under the floor is as low as the outside temperature, and if you try to reduce heat dissipation from the floor surface, it is necessary to use thick insulation material, which is expensive. Furthermore, the floor of a single-legged wooden house is a complex combination of joists, floorboards, floorboards, etc., and it is almost impossible to completely install insulation materials and moisture-proof layers. Not only does the cold air blow into the room as a so-called draft, degrading the living environment and increasing fuel consumption, but moisture from inside the room and from the ground beneath the floor condenses on the joists and floorboards, causing damage to the wood. There were drawbacks such as a severe decrease in durability.

Therefore, in order to solve the drawbacks of the conventional method, the inventor of the present invention, as a result of intensive studies, decided to attach an appropriately thick insulating material to the crystal and to solve the problem of insulating material of an appropriate thickness. The present invention was achieved by discovering that by placing the heat storage body under the floor and dividing the heat storage body under the floor, it is possible to prevent heat dissipation from the floor surface and to effectively recover the released heat. Ta.

In other words, the present invention provides a structure in which a heat insulating material 2 is attached to the inner or outer surface of a foundation 1, an embankment 3 is provided within the foundation 1, and a layer of cracked stone or cut gravel 4 is horizontally placed on the upper surface of the embankment 3. This is a heat insulation construction method in which a moisture-proof layer 5 is placed on top of the sand layer 5, a sand layer 6t-,t is packed on the top surface, concrete I-8 is formed on the sand layer 6, and a floor finish 9 is formed on the top surface. , the concrete/Ii #8 type also provides a high insulation construction method in which a heat insulating material T of an appropriate thickness is laid horizontally in the lower layer.

Moisture-proof No. 5 may be any material as long as it can prevent water from penetrating, and synthetic resin films such as polyethylene and vinyl are preferably used.

Next, one embodiment of the present invention will be described based on the drawings. li
The foundation of a building such as a house and is made of concrete or the like. Attach heat material 2 to the inner or outer surface of the foundation 1. Fill the foundation 1 with embankment 3 to an appropriate height and level the top surface. Fill and level the cut gravel layer 4. Lay the moisture-proof layer 5 on top of it. Lay the sand layer 6 on the top surface of the moisture-proof #5. The sand layer 6
tl-Purpose of packing, P, eliminate the unevenness caused by the cracked stones 4 etc. on the moisture barrier layer 5, level it out, and then apply the heat insulating material γ on top of it.
Alternatively, concrete No. 8 should be laid down evenly and horizontally. Therefore, it suffices if the objective is achieved in the number of sands of 6, and is not limited to 4. Insulating material Tf with a thickness of 4 degrees is placed on top of the sand No. 6. insulation material
A concrete layer 8 is formed horizontally on the upper surface, and a floor finish 9 is further formed horizontally on the upper surface.

In the present invention, the heat insulating material T is more F than the concrete layer 8.
It can be laid horizontally in layers, for example on the surface of the embankment 30 or in the embankment 3, and the cut pieces T can be laid not only in one layer but also in two or more layers. From the viewpoint of construction procedure and durability, it is preferable to lay the Liao thermal material T on top of the sand layer 6.

The heat insulating material 2, γ used in the present invention needs to have an appropriate thickness f. If the thickness of the heat insulating material 2, T is too thin, a sufficient heat insulating effect will not be achieved.

Regarding heat material 2, the loss of thickness and the radiation area of heat stored in the embankment will be reduced, but making it thicker will increase the price, and there will be a problem with the heat insulation material used for walls. There is no need to thicken the wall insulation. 1 as insulation material 2
In cold regions, the difference in filtration between the embankment and the outside air is 30 tons.
(In the case of this construction method, the temperature of the embankment can be maintained at 7 to 13 degrees Celsius), so the heat transfer coefficient is relatively small, preferably 0.3 to 0.5 Cal/ cm se
It is best to use a material with a temperature of 50 to 100 mm and a thickness of 50 to 100 mm.

Regarding the insulation material TK, if it is too thick, excess heat in the room will not pass through the insulation material T and be stored in the embankment 3.
It is wasted in raising the indoor temperature unnecessarily. By using an appropriately thick insulating material T, excessive heat will be dissipated from the floor surface, and if there is too much heat indoors, heat will be stored in the embankment 3 through the insulating material T. It is effectively used to warm the room when the heating is turned off and the room temperature drops. Since the temperature difference between the guide and the embankment is at most 10°C, the heat insulating material T has a relatively large thermal conductivity K, preferably 0.7 to 1.0 cal/cts sec, C.
It is desirable to use one with a thickness of about 20 to 40 mm. Furthermore, from the viewpoint of durability of the insulation material 2, T, it is better to use one with low hygroscopicity and water absorption.

For this purpose, the heat insulating material 2, T, is made of polystyrene, W! , quality JN urethane, hard polyvinyl chloride,
Plate-shaped foams such as phenol resins are suitable, and in particular,
Extruded foamed polystyrene plates are preferred.

In the present invention, by attaching the heat insulating material 2 to the foundation 1, the heat dissipated from inside the room is stored in the embankment 3, and the temperature of the embankment 3 does not drop below 0℃, causing the phenomenon of frozen ground. can be completely prevented, and furthermore, there is no need to drain water pipes to prevent water pipes from bursting.

Since the first aspect of the present invention is constructed as described above, indoor heat is not excessively absorbed through the floor surface, and heat storage in the concrete floor and the ground can be effectively used, resulting in extremely high energy consumption. 'thermal efficiency' can be achieved and significant energy savings can be achieved. In addition, the present invention divides the heat capacity of the heat storage body into a layer above the heat insulating material such as dirt floor concrete and a layer below the heat insulating material such as the ground by using the heat insulating material under the floor. This eliminates the drawback of slow response speed, which alleviates changes in room temperature and improves comfort.

Furthermore, according to the present invention, the amount of heat stored by the embankment 3 is not so large compared to conventional construction methods, so the thickness of the heat insulating material 2 can be reduced.
