Fabricated self-resetting rotation constraint type concrete beam-column joint connecting structure and assembling method

Abstract

The invention provides a fabricated self-resetting rotation constraint type concrete beam-column joint connecting structure and an assembling method. Transverse anchoring steel plate keys of the connecting structure are installed on the upper side and the lower side of the end of a prefabricated concrete beam, longitudinal anchoring steel plate keys are installed on the upper portion and the lower portion of a pre-embedded steel plate in a column, the longitudinal anchoring steel plate keys and the transverse anchoring steel plate keys are connected through rotating shaft bolts at the junction of beam-column joints, fan-shaped constraint steel plates and constraint rotating shafts between the longitudinal anchoring steel plate keys and the transverse anchoring steel plate keys are connected through constraint bolts, pre-tightening force applied to the rotating shaft bolts and the constraint bolts can effectively guarantee the flexural rigidity of the joints, and the joints are kept in an elastic state when the earthquake action is small. The problems that a dry type connection joint is poor in energy consumption and difficult to replace and repair after being damaged are effectively solved, connection between the prefabricated concrete beam and the prefabricated concrete column is achieved, and the requirements in actual design and construction are met.

Description

Technical field [0001] The present invention relates to an assembled self-reset rotational constraint concrete beam column node connection structure and assembly method, which belongs to the field of assembly concrete construction technology. Background technique [0002] As the assembled concrete structure, in order to achieve the effect of "equivalent casting", multi-beam column prefabrication, node is currently inset or the connection method of secondary pouring. Compared to the full range of cast structures, although this connection improves the construction efficiency, there is still a large amount of concrete and wet operation in the site, and it is impossible to meet the development of green and environmentally friendly and efficient energy saving of assembled buildings. In recent years, a dry-type connection technique represented by a sleeve grout connection, a constrained pulp anchor connection, and a backward belt connection, and gradually become the main way for the co...
