Prefabricated node and prefabricated frame structure and construction method thereof

Abstract

The invention discloses a prefabricated node and a prefabricated frame structure and a construction method thereof. The prefabricated node can be subjected to workshop prefabrication according to the structure. The prefabricated frame structure is mainly characterized in that the prefabricated node with a node overhanging beam section and a node overhanging column section is prefabricated, prefabricated nodes of various kinds are designed according to a graph, the prefabricated nodes are accurately mounted, and the overall prefabricated assembled integral type structure is constructed by means of connecting beams or columns of the prefabricated nodes in site. The construction method includes the steps of 1), positioning, lifting and correcting the prefabricated nodes in site; 2), fixing and mounting the prefabricated nodes; 3), casting a beam connection portion and a column connection portion in site. A novel construction mode is innovatively put forward for the prefabricated frame structure, and the node prefabricated structure with the beams and the columns is put forward; unfavorable situation that durability and reliability of the nodes are pool due to conventional prefabricated beams and columns and in-site casting of reinforced concrete nodes is favorably improved, construction time is saved, and construction cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of prefabricated and assembled integral structures, and in particular relates to a prefabricated node, a prefabricated and assembled frame structure and a construction method thereof. Background technique [0002] In recent years, prefabricated integrated structures have developed rapidly, especially in the 13th Five-Year Plan when the country proposed the development goal of building industrialization. Prefabricated assembly technology is the core of building industrialization, and it is promoting resource, energy-saving and environment-friendly buildings. development played a key role. Common prefabricated structural systems include: prefabricated concrete structural systems, prefabricated integral concrete systems, prefabricated integrated shear wall structural systems, prefabricated shear wall structural systems and other structural systems. [0003] The prefabricated assembly structure has the characte...
