Description

Technical Field

The utility model relates to the technical field of prefabricated prestressed assembled building construction, in particular to a post-tensioned bonded co-tensioned prefabricated prestressed concrete frame structure system connected by UHPC.

Background

The cast-in-situ structure has the defects of low construction efficiency, high energy consumption and the like, and is difficult to adapt to the development requirements of building industrialization. The prefabricated building has become the development direction of building industrialization due to the advantages of high construction speed, industrialized production of components, field wet operation reduction, environmental pollution reduction and the like. Through the development and popularization of the traditional Chinese medicine for many years, prefabricated concrete structures have been widely studied and used.

The prefabricated assembled concrete frame structure refers to a structure that beam column components are prefabricated in a prefabrication factory and transported to a construction site to be connected to form an integral structure. Compared with the cast-in-place concrete structure, the cast-in-place concrete structure has the advantages of high construction speed, easily guaranteed component quality, good quality, small environmental pollution, labor cost saving, a large number of templates and supports saving and the like, and is a structure form with very broad prospects. For the wet connection assembly type concrete frame structure, the node construction form which is easy to construct and effectively ensures the integrity is key to popularization and application. However, from the view of the past earthquake disasters, the assembled structure is seriously damaged in the earthquake, and the same earthquake-resistant performance as that of the cast-in-situ structure is difficult to achieve. In order to improve the integrity and reliability of the node connection of the fabricated concrete frame and achieve and even exceed the earthquake-resistant performance of the cast-in-place concrete structure, a pre-stress technology and UHPC (Ultra High Performance Concrete, ultra-high performance concrete) material are introduced into the fabricated structure.

The post-tensioned bonded co-tensioned prestressed assembled concrete structure is formed by splicing a prefabricated common concrete member and a prefabricated pretensioned prestressed member together through tensioning prestressed tendons, and has the characteristics of pretensioned prestressed, post-tensioned bonded prestressed concrete structure and assembled structure. The internal stress generated by the prestress on the concrete section can partially or completely offset the section stress under the load, delay the occurrence of cracks and improve the rigidity of the component. During unloading, the crack can be partially or completely closed, and the elastic recovery performance of the structure is good. Meanwhile, the prestressed concrete can fully utilize the material strength of the prestressed tendons and the concrete, and lighten the dead weight of the structure. And the application of the prestress is beneficial to the improvement of the usability and the integrity of the assembled structure, and the application of the assembled structure in a large-span and heavy-load structure is promoted.

UHPC has excellent bonding performance, and can greatly reduce the anchoring length of the steel bars and the steel strands in the UHPC; the strength is high, the hooping consumption of the node core area can be reduced, and the UHPC is used for the node core area, so that the structure is simple and the frame integrity is good. The pre-stress structure has excellent stress performance, and UHPC is applied to the node core area to form the pre-stress frame structure. The structure is subjected to intensive research, and is favorable for further popularization and application of the prefabricated prestressed concrete frame structure.
