Beam connection structure of assembly type concrete frame

Abstract

The invention discloses a beam connection structure of a assembly type concrete frame. The beam connection structure comprises a left pre-embedded section, a connecting section and a right pre-embedded section; the left pre-embedded section, the connecting section and the right pre-embedded section are all box type section steel components; the left pre-embedded section and the right pre-embedded section are both embedded in a reinforced concrete frame beam previously and become a part of concrete beam sections through concrete pouring and hardening; and during construction, the concrete beam sections are connected through the connecting section of the beam connection structure, so that the structure becomes a whole. The connecting section is designed according to the needs that the concrete frame beam forms a plastic hinge, and the carrying capacity is adjusted by a section dimension, so that the connecting section is in an elastic working condition in normal use; and when an extraordinary event occurs, the connecting section yields first and develops plastic deformation reliably. According to the beam connection structure of the assembly type concrete frame, construction is simple, when the extraordinary event occurs, the beam connection structure forms the plastic hinge to protect the other parts of the component from being damaged; and after the extraordinary event, the connection section with severe deformation can be replaced, and an excellent structural performance is achieved.

Description

technical field [0001] The invention belongs to the field of prefabricated assembled concrete structures in civil engineering, and in particular relates to a connection structure of concrete beams, which can be used as beam connection nodes of assembled concrete frames. Background technique [0002] The prefabricated concrete structure has the advantages of less environmental pollution, high production efficiency, short construction period, and installation without disturbing the people. The country is vigorously promoting it, and it is a very promising architectural structure form in the future. In the construction of prefabricated concrete structures, the connection method of prefabricated components at the construction site is related to the safety of the structure, the difficulty of construction, and has a great impact on the production cost; it also involves issues such as the repair of the structure after a major earthquake , can be said to be the key to the success or...

AI Technical Summary

Problems solved by technology

[0003] The connection structure of the existing prefabricated concrete structure is complex and costly; when an emergency occurs, the rigid connection structure is easily damaged, thereby destroying the integrity of the structure and causing collapse; the connection structure is irreplaceable, which increases the difficulty of overall repair
