Construction method for large steel structural embedded part in dense reinforcement distribution region

Abstract

The invention relates to a construction method for a large steel structural embedded part in a dense reinforcement distribution region. The method comprises the steps of mounting a bottom die and binding girder stirrups; binding a longitudinal main reinforcement; mounting transverse lacing wires and split bolts; mounting a bottom supporting frame; lifting a bottom plate of the embedded part; mounting a main side plate of the embedded part; mounting connecting reinforcements; lifting an auxiliary side plate of the embedded part; lifting an internal stiffened steel plate of the embedded part; mounting a connecting cover plate; mounting and reinforcing a template; performing concrete pouring; performing concrete curing; re-checking the position of the embedded part; and the like. With the adoption of the technology, firstly the steel reinforcements are bound with a post method, previously the main reinforcement is disconnected in the position of the embedded part, and the embedded part is lifted and assembled after the steel reinforcements are bound, so that the construction difficulties in subsequent steel reinforcement binding, stirrup mounting, prestress anchor cable positioning and reinforcement, and the like in a large steel structural embedded part project are effectively overcome; and therefore, the method has the advantages of capability of greatly shortening the later operation time, high construction efficiency and the like.

Problems solved by technology

[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.
