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

Abstract

The invention provides a fabricated concrete self-resetting beam-column joint connecting structure and an assembling method. A prefabricated reinforced concrete beam and a prefabricated reinforced concrete column of the structure are vertically connected through a connecting plate, pre-buried connecting steel plate grooves are formed in the connecting ends of the prefabricated reinforced concretebeam and the prefabricated reinforced concrete column correspondingly, and two sides of the connecting plate are connected with the two pre-buried connecting steel plate grooves; and prestressed tendons sequentially transversely penetrate through the prefabricated reinforced concrete beam, the pre-buried connecting steel plate groove in the prefabricated reinforced concrete beam, the connecting plate and the pre-buried connecting steel plate groove of the prefabricated reinforced concrete column and finally penetrate out of the prefabricated reinforced concrete column, each prestressed tendonanchorage device is correspondingly screwed and fixed at the extending end of the corresponding prestressed tendon, and energy dissipation dampers are mounted on the two sides of the connecting plate.The technical problems of how to develop a joint connecting mode which is environmentally friendly, easy to assemble, capable of effectively dissipating energy under the action of earthquake loads and meanwhile ensuring that the structure is small in deformation after an earthquake or can be restored to the initial state are solved.

Description

technical field [0001] The invention relates to a prefabricated concrete self-resetting beam-column node connection structure and an assembling method, belonging to the technical field of prefabricated concrete buildings. Background technique [0002] The beam-column components of the prefabricated concrete structure are mostly connected by beam-column prefabrication and joint cast-in-place connection, in order to achieve the purpose of "equivalent to cast-in-place". Using the cast-in-place connection method still requires a lot of concrete wet work on the construction site, which cannot meet the development concept of green environmental protection, energy saving and high efficiency of prefabricated buildings. In recent years, various dry connection methods and technologies have flourished, and methods such as sleeve grout connection, restrained grout-anchor connection and post-cast tape connection have become increasingly mature. Experimental research shows that this type...

AI Technical Summary

Problems solved by technology

Experimental research shows that this type of connection can effectively ensure the stiffness and bearing capacity of the joint connection area, and the force is reliable, but the energy consumption is poor, and the grouting is prone to brittle failure under repeated earthquake loads

At the same time, various grouting methods are relatively complicated, and the cost of materials and equipment used is relatively high
