Description

Detailed Description of the Invention [Industrial applications]

The present invention relates to a method of constructing a building with a basement by constructing an above-ground building in a row above the basement.

[Prior art]

Conventionally, when building a building with a basement, generally,
As shown in FIG. 10, a wall panel C, a floor panel D and a roof panel E are built in a hole to be dug in the ground in a cloth foundation B supporting the aboveground building A to construct a basement F, Backfilling concrete G between B and wall panel C is placed to construct a building with a basement.

[Problems to be Solved by the Invention]

In the above conventional technique, the propagation of force between the aboveground building A and the basement F is blocked by the backfilling concrete G, and the load of the aboveground building A cannot be supported in the basement F.
Moreover, even when various forces are applied, the above-ground building A and the basement F cannot act integrally, so that the above-ground building A
And the basement F must be designed separately by calculating the strength separately, which is disadvantageous in terms of strength and economy.
There is a problem that uneven subsidence of the cloth foundation B and uneven floating of the basement F may occur, and further, since the construction work method between the underground building A and the basement F is different, the construction work efficiency is also poor. There was a problem to say. The present invention is made to solve the above conventional problems, the load of the ground building can be supported in the basement, and, even when various forces are applied, the ground building and the basement Work together, which is economically rational in terms of strength, and can prevent differential subsidence of the ground building and differential lift of the basement, and also the construction work of the ground building and basement. Since the method is the same, the construction work efficiency is good, and in addition, even if there is a variation in the degree of concrete covering for the mesh-shaped reinforcements located on the outside, it is pre-welded and integrated inward so that the main reinforcement action is achieved. It is an object of the present invention to provide a method for constructing a building with a basement, which can reliably and accurately exhibit mechanical strength by virtue of the mesh-shaped arranging body to be exerted.

[Means for Solving the Problems]

In order to solve the above-mentioned problems, the present invention arranges a desired number of mesh-shaped bar arrangements that exert a main muscle action between two mesh-shaped bar arrangements that are arranged side by side with an interval. In addition, the entire mesh-shaped bar arrangements that are arranged in parallel are welded and integrated to form a bar arrangement unit, while a hole is dug in the ground to form a basement, and inside the hole, the wall of the basement is formed. , The floor portion, the roof portion, and the like, a desired number of the bar arrangement units are continuously connected to form a basement skeleton, and above the basement skeleton, the wall portion, floor portion, roof portion, etc. of the above-ground building are A desired number of the reinforcing bar units are continuously arranged at the constituent positions to form a ground building skeleton, and formwork panels are arranged near the outer surface and the inner surface of the reinforcing bar units constituting the basement skeleton and the ground building skeleton. With concrete inside the formwork panel And it is characterized in that was set to build a basement with the building.
