Steel plate confined concrete shear wall and steel framework thereof

Abstract

The invention discloses a steel formwork for a steel plate confined concrete shear wall, comprising a steel formwork body, the steel formwork body comprising a plurality of steel structures with cavities, the steel structures are seamlessly spliced ​​and fixed, and adjacent The steel structure is provided with a communication port for communication between the cavities of the steel structure at the position of the seamless splicing. The above solution is fixed through the seamless splicing of the steel structure cavity, and at the same time, the adjacent steel structure is provided with a circulation port for the communication between the cavities of the steel structure at the position of the seamless splicing. When pouring, the concrete can flow freely in the steel formwork body, so that the concrete is an integral structure after the pouring is completed, and the exterior of the concrete is wrapped and restrained by the steel structure as a whole. Therefore, the synergy between the steel plate and the concrete is greatly improved, and the Seismic performance of shear walls. In addition, the invention also discloses a steel plate confined concrete shear wall.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a steel plate confined concrete shear wall and a steel formwork thereof. Background technique [0002] Ordinary shear walls are generally made of steel and concrete. The steel bar is located inside the concrete and mainly bears tension and forms constraints on the concrete. The concrete mainly bears pressure and forms a package for the steel bar. [0003] With the continuous development of science and technology, architectural structures are also changing with each passing day. At present, the most common is the steel pipe bundle shear wall. Compared with ordinary shear walls, it avoids the process of manually binding steel bars, greatly reduces the site, and is convenient for construction and high in work efficiency. However, there are still some defects in the existing shear walls: first, due to the narrow space of the steel pipe beams, and the connection bet...

AI Technical Summary

Problems solved by technology

However, there are still some defects in the existing shear walls: first, due to the narrow space of the steel pipe beams, and the connection between the ends and the steel beams requires the installation of internal diaphragms, it is very difficult to pour concrete, and the pouring quality is not easy to control; second, If the steel pipe bundles are not provided with studs, the synergy between the steel and concrete will be weak. Therefore, some steel pipe bundles need to be equipped with studs to realize the cooperative work of steel and concrete, or some steel pipe bundles are provided with small holes on the web. holes instead of studs, but regardless of the structure of studs or small holes, the cooperating ability between steel and concrete is still weak; third, each steel beam is welded together, and the concrete inside is separated into bundles by steel beams. Form a whole so that the performance of the concrete material is not fully utilized

[0004] To sum up, how to solve the problem of weak synergy between the steel and concrete of the shear wall has become a technical problem to be solved urgently by those skilled in the art
