Description

Technical Field

[0001] The present application relates to the field of construction technology, and in particular to a method for tying assembled double-sided embedded steel bars. Background Art

[0002] Due to the many advantages of steel structure, such as high strength, light weight, good seismic performance and recyclable materials, building steel structure is widely used in modern construction, especially in some structures with large span, high height and heavy load. The advantages and functions of steel structure are remarkable. When the steel structure truss is connected to the concrete structure of the building, the corbel connection or embedded parts are generally used. When the truss cross-section is relatively large and embedded parts are used for connection, the size of the embedded parts will be relatively large. At the same time, due to the limitation of the cross-section of the concrete structure beam, in order to ensure the anchoring bearing capacity of the node, it is necessary to embed double-sided embedded parts to enhance the anchoring strength of the embedded parts.

[0003] Double-sided integral embedded parts are often used in structural design. The embedded parts are large in size and need to be installed by passing through the upper part of the longitudinal reinforcement of the frame column as a whole, or the stirrups at the integral embedded parts need to be processed into open stirrups. After the embedded parts are hoisted, they are bent and welded on site to close the loop. The longitudinal reinforcement of the frame column is usually large-diameter reinforcement and is arranged tightly. In actual operation, this causes great construction difficulties for the installation of embedded parts and the binding of reinforcement. Summary of the invention
