Pre-tensioning-method pre-stress superposed beam building structure system and construction process thereof

Abstract

The invention relates to a pre-tensioning-method pre-stress superposed beam building structure system. A pre-stress superposed framework beam is placed on a bracket of a cast-in-place framework column; a pre-stress superposed secondary beam is placed on a corresponding notch and a steel bracket of the pre-stress superposed framework beam; a superposed plate is placed on the bearing lug of the pre-stress superposed secondary beam; stressed steel bars are placed in upper corresponding superposed layers of a pre-stress superposed framework beam prefabricated component, a pre-stress superposed secondary beam prefabricated component and a superposed plate prefabricated component; and exposed hoop bars or anti-shearing keys of the pre-stress superposed framework beam prefabricated component, the pre-stress superposed secondary beam prefabricated component and the superposed plate prefabricated component are mutually bound; a framework column hoop bar at the crossed part of the cast-in-place framework column and the pre-stress superposed beam prefabricated component is placed and is bound with the vertical stressed steel bar of the framework column; and concrete is cast into the superposed layer of the pre-stress superposed framework beam, the pre-stress superposed secondary beam and the superposed plate, and the crossed part of the cast-in-place framework column and the pre-stress superposed beam.

Description

technical field [0001] The invention relates to a pretensioned prestressed composite beam building structure system and a construction technique thereof, belonging to the technical field of civil engineering. Background technique [0002] Frame structures are widely used in industrial buildings, commercial buildings, as well as office and residential buildings, but at present, the main structure of frame structure buildings is mainly produced in a completely cast-in-place manner. However, it is still necessary to set up support frames for prefabricated slabs and prefabricated beams. However, for large-scale industrial and commercial buildings with high storey heights and large spaces, ordinary prefabricated cast-in-place technology has to face the same dilemma as cast-in-place structures, that is, it is necessary to erect relatively large structures. High and high formwork, not only the cost of formwork is high, but the construction speed is slow, and high formwork is often ...

AI Technical Summary

Problems solved by technology

[0002] Frame structures are widely used in industrial buildings, commercial buildings, as well as office and residential buildings, but currently the main structure of frame structure buildings is mainly produced in a completely cast-in-place manner , although the main structure of some frame structure buildings adopts the prefabricated monolithic method, it still needs to set up support frames for prefabricated slabs and prefabricated beams. Technology has to face the same predicament of cast-in-place structures, that is, a relatively high formwork must be erected, so not only the formwork cost is high and the construction speed is slow, but the high formwork is often prone to instability problems, resulting in major quality problems. accident
