Abstract

Disclosed are a prestressed assembly integrated concrete frame structure system and a construction method thereof. The prestressed assembly integrated concrete frame structure system comprises prefabricated reinforced concrete columns, prefabricated prestressed concrete beams, prefabricated prestressed concrete plates and a floor slab laminating layer cast on the prefabricated prestressed concreteplates; the junctions of the prefabricated reinforced concrete columns and the prefabricated prestressed concrete beams are provided with first column hole channels and second column hole channels; the portion, close to the bottom, of each prefabricated prestressed concrete beam is provided with a row of pretensioned prestressed tendons, and the prefabricated prestressed concrete beams are internally provided with first beam hole channels adapting to the first column hole channels and second beam hole channels adapting to the second column hole channels; splicing seams of the prefabricated reinforced concrete columns and the prefabricated prestressed concrete beams are filled with high-strength mortar. The system solves the technical problems that traditional assembly integrated structuresystems are complicated in structural form, difficult in joint connection, large in wet work amount and unlikely to meet the requirements of different seismic fortification zones.

Description

technical field [0001] The invention belongs to the field of building construction, and in particular relates to a prestressed assembled integral concrete frame structure system and a construction method thereof. Background technique [0002] The prefabricated concrete structure is one of the important structural systems to realize the modernization of the construction industry. The prefabricated construction method is conducive to improving the construction quality and construction efficiency. Common prefabricated concrete structure systems include: cast-in-place column precast beam structure system, cast-in-place node structure system, self-resetting prestressed concrete frame structure system, assembled integral prestressed concrete frame structure system, etc. [0003] Cast-in-place column prefabricated beam structure system: beams and slab components are prefabricated in the factory, and concrete columns are cast-in-place. The prefabricated slabs are placed on the b...
