Assembled prestressed concrete frame structure

Abstract

An assembled prestressed concrete frame structure comprises a precast column and a precast beam. The precast beam comprises a precast primary beam and a precast secondary beam. The precast column is connected to one end of the precast primary beam with a joint zone formed at the joint. The precast column is divided into an upper precast column and a lower precast column at the joint zone. A horizontal connecting steel plate is embedded in the end, connected to the precast primary beam, of the upper precast column, and a first bracket is precast at the end, connected to the precast primary beam, of the lower precast column. The end, connected to the precast column, of the precast primary beam is located between the horizontal connecting steel plate and the first bracket and connected by means of a first pre-tightening connecting bolt. A prestressed reinforcement passage is preformed within the precast primary beam in a length direction thereof. A prestressed reinforcement is arranged within the prestressed reinforcement passage, and both ends of the prestressed reinforcement are anchored to the precast column. The invention provides an assembled prestressed concrete frame structure capable of suppressing dust and prone to promotion.

Description

technical field [0001] The invention belongs to the technical field of assembled buildings, in particular to an assembled prestressed concrete frame structure. Background technique [0002] Industrialized buildings are gradually replacing large-scale on-site production buildings at home and abroad, using factory prefabrication and assembling in construction workshops. This is the direction of the development of the construction industry and has become a national strategy for the development of my country's construction industry to be vigorously implemented. At present, the main structural form of industrial buildings is the assembled integral concrete structure, that is, the main structural components are prefabricated in the factory, assembled on site, and part of the concrete is poured locally, so that the components are connected into an integral structure. [0003] The existing prefabricated integral concrete frame structure system is mainly prefabricated beams and slab ...

AI Technical Summary

Problems solved by technology

This wet-assembled monolithic concrete structure can greatly reduce the amount of on-site concrete construction, but it is still necessary to retain the entire set of on-site concrete pouring process, which also brings a lot of dust to the construction site and has a certain impact on the urban environment.
