Problems solved by technology

[0003] At present, the connection between multi-section precast concrete columns in the domestic prefabricated concrete frame structure system is usually connected by sleeve grouting, but the grouting construction is complicated and the construction period is long, and the requirements for process quality are high, which makes the joint cost of precast concrete columns relatively high. High, which affects the assembly efficiency of the concrete frame structure system

Abstract

The present application provides a prefabricated prestressed concrete frame system and a construction method, the frame system includes hollow prefabricated columns and prefabricated composite beams, the prefabricated composite beams are arranged along the circumference of the hollow prefabricated columns, and are fixedly connected On the hollow precast column, the interior of the hollow precast column is poured with concrete; the hollow precast column includes an upper section precast column and a lower section precast column, and the upper section precast column and the lower section precast column pass through multiple Two column connectors are stacked and connected; the column connectors are pre-embedded in the upper prefabricated column, and the lower prefabricated column is pre-embedded with threaded steel bars, and the column connectors are provided with connection holes , after the threaded steel bar passes through the connecting hole, it is tightly connected with the locking nut. According to the prefabricated prestressed concrete frame system and construction method provided in the present application, rapid docking between multiple hollow prefabricated columns can be realized, the requirements for hoisting equipment are reduced, and the construction cost is greatly saved.

Description

technical field [0001] The present application relates to the technical field of building structure systems, in particular to a prefabricated prestressed concrete frame system and a construction method. Background technique [0002] The prefabricated concrete frame structure system is widely used due to its advantages of fast construction speed and good social and environmental benefits, and its seismic performance is mainly determined by the connection nodes between the prefabricated components. [0003] At present, the connection between the multi-section precast concrete columns in the domestic prefabricated concrete frame structure system usually adopts the sleeve grouting connection, and the grouting construction is complicated, the construction period is long, and the process quality is high, which makes the precast concrete column joint cost comparison high, which affects the assembly efficiency of the concrete frame structure system.
