Abstract

(57) 【Abstract】 PROBLEM TO BE SOLVED: To provide a device for preventing floating of a building skeleton, in which the amount of earthwork is reduced and the construction cost is reduced. SOLUTION: A reinforced concrete body 2 is fixed to a foundation 1 of a structure body via a reinforcing bar 3 embedded in the body, and the body 2 is filled with iron ore 4.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for preventing floating of groundwater acting on the lower surface of the foundation of a building frame.

[0002]

2. Description of the Related Art Conventionally, as a counterweight for preventing the rising of a structure a, solid concrete b has been placed as a counterweight for preventing the rising by over dug a lower part of the foundation of the structure. (See Fig. 2)

[0003]

In the above-mentioned prior art, since the lower part of the foundation of the structure is overexcaved and solid concrete for counterweight is placed in the overexcavation part, the amount of root cutting soil and the amount of excavated soil There is a problem in that the amount becomes large, the material is wasted, which contradicts resource saving and increases the cost.

The present invention has been proposed in view of the above problems of the prior art, and the purpose thereof is to reuse resources, reduce the amount of earthwork, and reduce the construction cost. The point is to provide a floating prevention device.

[0005]

Means for Solving the Problems In order to achieve the above-mentioned object, a device for preventing a structure body from rising according to the present invention comprises a reinforced concrete body through a reinforcing bar embedded in the body of the structure body. In addition to being fixed, the inside of the body is filled with iron ore.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described below with reference to the most preferred embodiment shown in the drawings. In FIG. 1, 1 is a foundation of a building frame, 2 is a reinforced concrete body, and the reinforcing bars 3 arranged in the body 2 are fixed to the foundation 1, and the iron ore 4 (specific gravity is set in the body 2). 3.8) is filled.

Since the illustrated embodiment is constructed as described above, the body 2 and the iron ore 4 filled in the body 2 act as a counterweight to prevent the structure body from floating.

[0008]

As described above, according to the present invention, as described above, the structure is made of reinforced concrete without being dug under the foundation of the structure as before, and without placing solid concrete as the counterweight for preventing floating. While fixing the body to the foundation of the structure through the reinforcing bar arranged in the body, by filling the body with iron ore, it is possible to prevent the structure body from rising. Resource can be reused compared to
The amount of unloaded soil will be reduced and the cost will be significantly reduced.
