A construction method of large-scale steel structure embedded parts in dense reinforcement area

Abstract

The present invention relates to a construction method of large-scale steel structure pre-embedded parts in a dense reinforcement area, which includes the installation of bottom formwork, the binding of main beam stirrups, the binding of longitudinal main reinforcements, the installation of transverse tension bars and tension bolts, the installation of bottom support frames, Bottom plate hoisting of embedded parts, installation of main side panels of embedded parts, installation of connecting steel bars, hoisting of auxiliary side panels of embedded parts, hoisting of stiffened steel plates inside embedded parts, installation of connecting cover plates, installation and reinforcement of formwork, concrete pouring, concrete curing, pre-embedded parts Embedded position review, etc. In the present invention, by adopting the above-mentioned technology and post-positioning method, the steel bars are bound first, and the main bars are disconnected at the position of the embedded parts in advance. After the steel bars are bound, the embedded parts are hoisted and assembled. In the embedded parts project, the subsequent construction difficulties such as binding of steel bars, installation of stirrups, and positioning and reinforcement of prestressed anchor cables have the advantages of greatly shortening the post-operation time and high construction efficiency.

[0002] In recent years, with the rapid development of the construction industry, in addition to meeting the basic requirements, the design functions of modern building structures have added requirements such as landscape and artistry, which has led to the emergence of a large number of reinforced concrete structures with complex structures and various forms during construction. , some of the embedded parts of the truss support in the steel structure of the main building are quite complex and difficult to construct

[0003] Generally, pre-embedded large-scale steel structure components are usually positioned and installed first, and then followed by subsequent processes such as steel bar binding. The installation of parts will make the subsequent steel bar binding and spiral hoop installation and construction quite cumbersome. If the structure also involves prestressed anchor cables, its positioning and reinforcement will be extremely difficult.
