It is a precast concrete structure using an industrialized construction method, which can be roughly classified into a panel type and a unit type. (3). It is steel construction by the industrialized construction method,
It can be roughly divided into panel type and unit type. (Four). This is a tree structure based on the 2 × 4 construction method, which has not been put to practical use in Japan. (Five). Capsule structure made of polymer material, especially suitable for small scale, resin concrete or FRP
Are used.

[0004]

In the above-mentioned conventional construction method,
There are the following problems.

[0005] First, reinforced concrete construction by field construction has the advantage of being able to flexibly respond to site conditions, but on the other hand, quality control and cost management vary widely, requiring advanced technology, and small basement rooms require high costs. Become.

[0006] The precast concrete structure is excellent in the homogeneity of the quality of the members and the workability, but it is difficult to perform the watertight construction of the joints, and the load of the hoisting machine and the transport vehicle becomes large due to the weight of the members. However, there is a problem that a turn cannot be made and a carry-in operation cannot be performed on a narrow road.

[0007] The steel structure by the industrialized construction method is a system that maximizes the advantages of industrialization.
Worry about rust prevention durability. Moreover, since it is a kind of box made of steel, the cost is 20 to 30% higher than that of a general construction method.

Since 2 × 4 has a tree structure, it is essentially unsuitable for Japan. The capsule structure is suitable for a small basement, but has a problem in durability.

SUMMARY OF THE INVENTION An object of the present invention is to solve the conventional disadvantages and to provide a low-cost and durable basement construction method.

Things.

[0013]

In the basement according to the present invention, the floor is first constructed with cast-in-place concrete, and then the wall panels are installed thereon. Since the floor is made of integral concrete, the seam is formed. There is no need to consider waterproofing. In addition, a sufficient waterproof construction can be performed at a joint between the floor concrete and the steel wall panel and a joint between the wall panels by interposing an appropriate waterproof seal.

In particular, even though the concrete on the floor is cast in place, it is only cast flat on the bottom of the underground part where the ground has been excavated or the like. No work required,
Since quality control such as accuracy is easy, the construction can be performed at a relatively low cost in consideration of the cost of transporting a large-sized floor panel such as the steel structure basement by the conventional industrialization.
