After macadam foundation work is provided, resin film K is spread all over, and a foaming thermal insulation plate L is spread on a whole face or a part of a lower part of earthen floor bars M to place earthen floor concrete N in order to increase thermal insulation, waterproof, and moistureproof effects.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION It is well known that an underground building has been known to be excellent in heat insulation and airtightness. However, in the present invention, an underground building excellent in moisture proofness, heat insulation and airtightness is known. Set a low price and offer it to society widely.

[0002]

2. Description of the Related Art Underground buildings in Japan include a restaurant area, a water receiving tank and a general drainage tank, or a machine room.
It is built mainly for underground parking.

[0003] In Japan, the following can be considered as a reason for constructing an underground building for such a use.

(1) In constructing an underground building,
The high cost and difficulty of civil engineering construction has hindered progress.

[0005] Therefore, in a building whose construction work cost is relatively expensive, the building is constructed in consideration of the foundation of the building itself and the balance of the whole building, but it is not generally used for other purposes. It is the current situation.

(2) Although underground structures are excellent in heat insulation and airtightness, they are often hesitant to construct them in terms of hygiene against mold, germs, etc., since no measures are taken and no measures are taken against moisture-proof surfaces. Can be seen.

[0007]

The reasons for the high cost and difficulty of civil engineering construction in the prior art (1) are foundation work and concrete pouring work on the basement.

[0008] In carrying out this work, excavation work of the basement, earth retaining work, crushed stone work (including pile driving, compaction, etc.), formwork and foundation work, formwork removal work after concrete placement In addition, there is removal work of earth retaining sheet pile.

[0009] These constructions are all difficult works, but in particular, removal of earth retaining sheet piles and formwork after concrete casting is a highly difficult construction that requires human life. is there.

Further, it is necessary to consider measures for the moisture-proof surface by groundwater and rainwater. The measures for these are
It is defined as one of the tasks to provide a basement space with excellent hygiene environment, as it responds to the propagation of mold, germs and the like.

[0011]

In the present invention, in order to solve the above-mentioned problems, a foamed frame material is used, and a foamed heat insulating plate is laid on a part or the entire surface of the bottom of the concrete slab.

In addition, a waterproof sheet is adhered to the entire outer side surface of the foamed frame material, and is a top surface on which crushed stone work (including pile driving, compaction, etc.) has been performed, and is laid on the bottom of the interstitial concrete. A resin film is spread between the foamed heat insulating plate and the heat insulating board.

[0013]

An embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a sectional view showing an underground building, FIG. 2 is a plan view showing a part of the underground building, and FIG. 3 is a sectional view of a part Z in FIG.

After excavating a part to be an underground building, earth retaining work is performed, crushed stone ground business G (including pile driving, compaction, etc.) is performed, and resin film K is spread.

[0015] A foam insulation board L is laid on a part or the entire surface corresponding to the bottom portion of the concrete slab N, the slab arrangement M is provided, and concrete is cast, whereby the concrete slab N is completed.

While constructing the side wall reinforcement D and the partition reinforcement,
A foam outer wall form member A and a foam partition form member T are set. When the underground building room X is represented, concrete is cast, and the outer wall concrete B and the partition concrete S are expressed.

Furthermore, after cleaning the outer surface of the foamed outer wall frame material A, a waterproof sheet C is adhered to the entire outer side surface, and when the earth retaining sheet pile is removed, backfilling is performed, and the underground building room X
To form

[0018]

Conventionally, plywood panels (concrete panels) have been the mainstream for formwork used in building construction, and after casting concrete, the work of removing the formwork and removing it has inevitably occurred. .

[0019] The main material of these plywood panels is wood, and today, there is a worldwide problem of destruction of nature due to the deforestation of forest resources. Because it is not used, it is also effective for protecting natural resources such as forest resources.

Further, since no formwork removal work is required after the concrete is cast, the industrial waste can be greatly reduced, and the illegal dumping of industrial waste can be reduced.

Further, since no formwork removal work is required in the construction process, the number of personnel is greatly reduced, and thus the construction cost is significantly reduced.

Next, after crushing ground work (including pile driving, compaction, etc.) is performed, a resin film is laid, and a foam insulation board is laid on a part or the entire surface corresponding to the bottom portion of the interstitial concrete. After cleaning the outer surface of the material, apply a waterproof sheet to the entire outer side surface.

In the underground building room constructed in this way, the effects of groundwater and rainwater are completely shut out, so that the moisture-proof effect is greatly improved, and
The breeding of various bacteria has been significantly reduced, and an underground space with an excellent sanitary environment can be provided.
