Reinforced concrete prefabricated integrally-cast building structure system and construction method thereof

Abstract

The invention relates to a novel reinforced concrete prefabricated integrally-cast building structure system, which comprises a floor slab, superposed beams and columns and / or shearing walls. Each superposed beam comprises a primary beam and a secondary beam and consists of a prestressed prefabricated beam and a cast-in-situ part. The prestressed prefabricated beam comprises a beam body and prestressed steel stranded wires. Section steel is arranged at the end parts of the beam body. One part of the section steel is buried in the beam body and the other part of the section steel is exposed at the end part of the beam body. The prefabricated beam in the primary beam is connected with the columns and / or the shearing walls through the section steel. The prefabricated beam in the secondary beam is placed on the primary beam through the section steels. A plurality of template supporting holes are longitudinally arranged on the beam body of the prefabricated beam of the secondary beam and the beam body of the prefabricated beam of the primary beam in parallel with the secondary beam. By adopting the prefabricated beams to be integrally cast with the cast-in-situ beams and the cast-in-situ floor slab to form a structure system, the prefabricated beams are fabricated by adopting a pre-tensioning prestressed technique and can be produced on a large scale in plants at one time and the production cost is reduced.

Description

technical field [0001] The invention relates to a building structure system, in particular to a building structure system composed of beams, columns and plates, and a construction method for building the system. Background technique [0002] The main structure in the house construction in the prior art is generally a structural system consisting of columns, beams, and slabs. The beams, slabs, and columns can be constructed in two ways: prefabricated and cast-in-place. With the continuous increase of raw material prices and labor costs, the all-cast-in-place construction technology has become increasingly prominent, such as bulky, consumable materials, large consumption of wooden formwork, and extensive labor. In addition, the revision of the new seismic code has also made it The cost advantage is gradually disappearing. The component joints of traditional prefabricated monolithic structures are complicated, and the amount of steel used is large, and the integrity is poor. ...

AI Technical Summary

Problems solved by technology

Since both the beam body and the floor slab in the above scheme adopt prefabricated structure, the slab is heavy and costly, the steel consumption of the beam is large, and the structural integrity is poor.
