Setting method of steel tube and hole-opening end plate embedded part

Abstract

The invention discloses a setting method of a steel tube and hole-opening end plate embedded part, belonging to the field of building structures and solving the problems that the end part is difficult in hooping because a support seat embedded base plate with a top steel structure of the traditional reinforced concrete cantilever column requires to be provided with a steel shear resistant part and a tensile anchor bolt; and the compact of the concrete cannot be ensured because longitudinal reinforcing bars and tensile anchor bolts are dense and the like. By using the technical scheme of the invention, a steel tube and a hole-opening end plate are welded and then arranged at the top of the reinforced concrete column, the longitudinal reinforcing bars in the column penetrate out of holes preserved in the end plate and concrete is cast into the concrete casting holes preserved in the end plate; and after the concrete is hardened, the longitudinal reinforcing bars and the end plate are welded together; and finally, excessive reinforcing bars are cut off. The invention provides a steel structure support seat embedded part which is installed rapidly, has a simple force transmission path, is convenient to cast the concrete and can ensure the quality of casting the concrete on the top of the column.

Description

technical field [0001] The invention belongs to the field of building structures, in particular to an embedded part for structural connection between a steel structure support and a reinforced concrete cantilever column. Background technique [0002] In public buildings such as stadiums, reinforced concrete cantilever columns are often used to support large-span steel structures on the roof. The support of the steel structure needs to be connected with the reinforced concrete cantilever column to transmit the force on the node. The traditional method is to install steel shear parts under the support bottom plate and pre-embed tension anchor bolts to realize the connection between the support and the reinforced concrete column. active connection. Due to the large section size of the pre-embedded steel shearing parts under the base plate of the support, it cannot pass through the horizontally arranged stirrup gap in the reinforced concrete column, so some stirrups within the ...

Problems solved by technology

[0003] The purpose of the present invention is to solve the problems that it is difficult to install stirrups at the top of the reinforced concrete column when the traditional steel support is connected with the reinforced concrete cantilever column, and it is difficult to ensure the quality of the concrete at the end connection. Therefore, the present invention provides a steel pipe -Setting method of embedded parts of open end plate
