DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for forming a foundation such as a house having a novel structure. In particular, it is suitable for the following points. 1. The housing and construction period of about 2 weeks is about 3 days. 2. The work becomes simple on site. (Temporary frame and others do not have to wait) Especially in the winter season, curing is not required and the cost can be reduced compared to the conventional method.

[0002]

2. Description of the Related Art A conventional method of forming a foundation has the following configuration. 1. After excavation, bring in temporary frame material for concrete placement,
Assembling while generating noise over several days. 2. After the concrete has been beaten, after a period of curing for several days, the temporary frame is removed, loaded in the trunk and brought back. 3. After that, fill the soil around the building and spread it out.

[0003] That is, the basis for constructing a house A1 in a floor plan shown in Fig. 1 is as follows. 1. The so-called short pre-computer foundation A2 shown in FIG. 2. The so-called cast-in-place concrete foundation A3 shown in FIG. 3. The so-called long pre-computer foundation A4 shown in FIG.

[0004]

The above-mentioned prior art has the following problems. 1. It took about two weeks from the excavation to the completion of backfill. 2. In particular, concrete casting under bad conditions due to concrete casting or rain during the winter period may not provide sufficient strength. 3. For the above two reasons, there is a problem in the service life. 4. In particular, construction work in densely populated areas such as houses increases the number of times materials are transported, and places a burden on nearby areas due to noise generated when the temporary frame is attached.

The present invention has been made in view of the above-mentioned problems of the prior art, and has as its object to provide the following. At the factory, temporary frames are assembled in the same way as at the site and concrete is poured. After curing, the temporary frame and the frame for forming the partition / connection portion are separated, and various basic blocks in the unit state are brought to the construction site and assembled. By doing so, you will always be able to get the same thing that was made at the factory. Concrete or grout is injected into the joint. The temporary frame can be assembled simply by attaching cloth tape and gum tape using conventional veneers.

[0067]

EXAMPLES As a result of an experiment under the following conditions, extremely good results were obtained. The experiment was performed in a snowstorm at about -10 ° C. Various foundation blocks manufactured at the factory were brought to the site on the ground sand bed to construct a building foundation of about 60 tsubo. There was no problem at all. The work was completed in two days with three people. A hotbed wire (heating wire) was put in the concrete or grout injection part and cured. Since various foundation blocks are placed directly on the sand bed, concrete is only used for grouting at the site. It is considered that the construction in the cold region is optimal and the construction in the winter period of the building becomes possible. Also,
Regarding transportation, in the case of the conventional short pre-computer, the number of short T-type base blocks, L-type base blocks, ten-type base blocks, etc. increases, and it is necessary to secure a large space. Since the base block, the L-shaped deformed base block, the T-shaped base block, and the like were used, the space was small and the cost could be reduced.

[0068]

Since the present invention is configured as described above, the following effects can be obtained. 1. The process that took about two weeks with the conventional method can be reduced to about three days. 2. Especially in the winter construction, it is possible to bring the strictly controlled factory to the site with sufficient strength. 3. Due to the above two reasons, the service life can be sufficiently ensured, and sufficient strength can be exerted against an earthquake. 4. Since there is almost no noise, there is no annoying surroundings, and the number of trucks carried in is reduced. 5. Aesthetically good. 6. In addition, the following effects can be expected for each invention. A. Regarding the second invention Since the horizontal connecting portion is provided, by filling this portion with concrete or grout, it is possible to prevent a lateral displacement occurring in an earthquake-prone area or the like. B. Regarding the third invention Since the upper vertical connecting portion and the lower vertical connecting portion are provided, necessary strength can be secured when the rising portion is made high. Furthermore, since the horizontal connecting portion is provided, by filling this portion with concrete or grout, it is possible to prevent lateral displacement occurring in an area where earthquakes frequently occur.
