Description

Steel-reinforced concrete reinforced concrete seismic strengthening structure and column surrounding beam stirrup structure

The present invention relates to a steel structure, in particular to a steel reinforced concrete seismic reinforced structure and a column bundle reinforcement for the steel reinforced concrete seismic strengthening structure.

Consumers have a need for earthquake-resistant safety for home construction. However, the seismic strength of residential buildings is mainly determined by the reinforced concrete wall plate and the steel structure of the column beam, especially the traditional reinforced concrete (RC) structure, but the steel structure is covered by concrete, so it is very difficult to test it. Shock resistance. It can be seen from this that in practice, it is difficult for consumers to ensure the safety and seismic quality of the buildings they live in.

Furthermore, the RC composite structure is relatively rigid and heavy in weight. When applied to high-rise buildings, it is necessary to use thicker beams and columns to support the whole building when the load layer is accumulated. It is difficult to construct and the space available for indoor use is reduced. Therefore, the steel-reinforced concrete mixed-soil (SRC) structure and the steel-stem (SC) structure suitable for high-rise buildings have been developed, and in residential buildings, the steel-reinforced concrete mixed-soil (SRC) structure is most popular. .

The steel-reinforced concrete mixed-soil (SRC) structure combines the structural form of steel and reinforced concrete. It is in the outer layer of the steel and is additionally equipped with steel bars and grouted to form a protective layer. Therefore, it has the characteristics of two structures, using steel. The bone can increase the strength of the column without adding a thick column, and the structural characteristics of the reinforced concrete can reduce the problem of excessive deformation of the pure steel structure when subjected to lateral force, and can reduce the time of the earthquake.
