Description

Column bundle stirrup for steel reinforced concrete seismic strengthening 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 home construction is mainly determined by the reinforced concrete wall plate and the steel structure of the column beam, especially the traditional reinforced concrete (RC) structure. Although it is one of the most mature building structures, the number of steel bars Whether the number, number, and lashing will affect the strength, but the steel structure will be covered by concrete, so it is very difficult to test its seismic strength. Consumers often have no way to see the construction process of the steel structure on the construction site. Trust the construction quality of construction workers. 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, reinforced concrete (RC) is relatively rigid and has a heavy 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 not easy to construct. The space available for indoor use is reduced. Therefore, the steel reinforced concrete (SRC) structure and the steel skeleton (SC) structure suitable for high-rise buildings have been developed, and in the residential buildings, the steel-reinforced concrete (SRC) structure is most popular.

The steel reinforced concrete (SRC) structure combines the structural form of steel and reinforced concrete. It is additionally arranged with steel bars and grouted to form a protective layer on the outer layer of the steel. Therefore, it has the characteristics of two structures. The thickened cylinder can increase the strength of the cylinder. The structural characteristics of reinforced concrete can reduce the problem of excessive deformation of pure steel structure when subjected to lateral forces, which can reduce the degree of shaking during earthquakes.

However, in the steel-reinforced concrete (SRC) structure, the steel, steel and concrete are combined, so the construction cost and method are more complicated. In view of the current uneven quality of the steel work and the long age, If the construction quality of traditional construction methods is too much, it is impossible to meet the demand for higher steel structure quality in today's high-rise buildings. Therefore, if the reinforcement of the steel structure can be considered in advance in the structural design of the steel bar and the steel bar processing stage, the lining positioning and simplification of the steel structure can make the reinforced steel work class quickly and accurately complete the design requirements of the steel structure designer.

Therefore, what is needed now is a steel reinforced concrete (SRC) structure and related construction method, which can make the safety and seismic quality of the building structure continue from the design to the construction site, and let the design end of the steel structure from the processing end of the steel material to the steel structure. Both the construction and the planning stage are considered in advance, and each detail and detail of the site construction can be ensured, so that the consumer is more assured of the quality of the building.

In view of the above-mentioned problems of the prior art, the purpose of the present invention is to provide a column bundle stirrup for a steel reinforced concrete (SRC) seismic strengthening structure, which is bent by a steel bar to form a closed quadrilateral. The reinforcing steel structure, and the plurality of curved corner portions of the closed quadrilateral have a fastening region, the closed quadrilateral is for a steel skeleton to be pierced, and each of the fastening regions is for the plurality of pillar steel bars to be pierced and tied.
