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

Abstract

The invention provides a fabricated concrete frame beam column self-resetting combined joint connecting structure and an assembling method. Clamping groove type steel plate keys are mounted on the upper side and the lower side of the beam end of the structure, a prefabricated reinforced concrete column and a prefabricated reinforced concrete beam are perpendicular to each other and are connected through cooperation of strip-shaped connecting steel plates and the clamping groove type steel plate keys, the strip-shaped connecting steel plates and the clamping groove type steel plate keys are fixed through rectangular restraining pieces, non-bonded prestressed tendons transversely penetrate through the whole formed by the prefabricated reinforced concrete column and the prefabricated reinforced concrete beam, and the ends of the non-bonded prestressed tendons are fixed through a plurality of prestressed tendon anchorage devices. The technical problems of how to reduce deformation and damage of prefabricated parts after an earthquake to the maximum extent and how to ensure the restorability of a joint core area are solved, the fabricated concrete frame beam column self-resetting combined joint connecting structure is provided, and a fabricated concrete frame beam column joint has certain self-resetting capacity and can restore to the original initial state after the earthquake.

Description

technical field [0001] The invention relates to a prefabricated concrete frame beam-column self-resetting composite node connection structure and an assembling method, belonging to the technical field of prefabricated concrete buildings. Background technique [0002] Prefabricated concrete structures have been vigorously promoted in my country in recent years due to their advantages of fast construction speed, energy saving, environmental protection, time saving and high efficiency. In the traditional prefabricated concrete frame structure, only the beam-column components are prefabricated, and the nodes need to be cast in situ, which is the so-called assembled monolithic structure, resulting in a low structural assembly rate. However, using the cast-in-place node connection method still requires a lot of concrete wet work on the construction site, which cannot meet the green, energy-saving and efficient development concept of prefabricated buildings. [0003] Since the 21s...
