Abstract

The invention discloses a mixed-connection post-tensioned prestressing assembly concrete frame system and a construction method thereof. The mixed-connection post-tensioned prestressing assembly concrete frame system comprises a foundation, a frame column, a frame beam and a floor; a connecting reinforcement is buried in the deigned position, inside the foundation, corresponding to the frame column, and the connecting reinforcement is in an L shape and comprises vertical edges and transverse edges connected to one sides of the bottom ends of the vertical edges; the lower portions of the vertical edges of the connecting reinforcement and the transverse edges are buried in the foundation, and the portion, buried in the foundation, of the connecting reinforcement comprises connecting reinforcement bonding sections and connecting reinforcement non-bonding sections; the connecting reinforcement non-bonding sections are located on the positions, located on the lower side of the top surface of the foundation and close to one end of the foundation, of the vertical edges, and the lengths of the connecting reinforcement non-bonding sections are 3-20 times the diameter of the connecting reinforcement; and the connecting reinforcement bonding sections are located on the positions, located on the lower side of the top surface of the foundation and close to one ends of the transverse edges,of the vertical edges and the transverse edges of the connecting reinforcement. According to the mixed-connection post-tensioned prestressing assembly concrete frame system and the construction methodthereof, the technical problems that in an existing structural system, the transporting hoisting difficulty is large, the structural robust property is low, the wet working quantity is large, and therepairing cost of column feet after earthquakes is high are solved.

Description

technical field [0001] The invention belongs to the field of prefabricated concrete structure buildings, in particular to a mixed-connected post-tensioned prestressed assembled concrete frame system and a construction method thereof. Background technique [0002] At present, most of the prefabricated concrete structures used in the domestic civil construction field are prefabricated integral structural systems, mainly including prefabricated integral frame structures, prefabricated integral frame-cast-in-place shear wall structures, and prefabricated integral shear wall structural systems. These systems are cast-in-place in the beam-column joint area, which requires a large amount of wet work on site and low construction efficiency. In recent years, the United States and Japan have developed several prefabricated prestressed frame dry connection joints and systems that can be applied in civil buildings, but there are still some problems that need to be improved: 1. Usually, ...
