Self-resetting shearing-constrained buckling damage-controllable fabricated beam-column joint

Abstract

The invention provides a self-resetting shearing-constrained buckling damage-controllable fabricated beam-column joint. The self-resetting shearing-constrained buckling damage-controllable fabricatedbeam-column joint comprises a prefabricated column (1), a prefabricated beam (2), a pin shaft (8), a shear buckling plate (9) and an elastic piece (12); the prefabricated column (1) and the prefabricated beam (2) are fixedly connected with a column double-T-shaped connecting plate (6) and a beam T-shaped connecting plate (7) respectively; the column double-T-shaped connecting plate (6) is connected with the beam T-shaped connecting plate (7) in a hinged mode through the pin shaft (8); the shearing buckling plate (9) is constrained between a first constraining plate (10) and a second constraining plate (11) through bolts; and the shearing buckling plate (9) and the elastic piece (12) are respectively fixed between the column double-T-shaped connecting plate (6) and the beam T-shaped connecting plate (7) through bolts and clamps (13). Deformation and energy consumption of beams are concentrated at connecting positions, energy consumption and flexural rigidity are provided for multiple benches, large plastic damage to components is avoided, and the structure function can be rapidly recovered.

Description

technical field [0001] The invention relates to an assembled structure node technology, which is mainly used for an assembled frame structure beam-column node. Background technique [0002] As a pillar industry of the national economy, the construction industry currently mainly relies on the input of resource elements and large-scale investment to drive development. Its industrialization and informatization level are relatively low, its production methods are extensive, its labor efficiency is not high, its consumption of energy and resources is large, and its ability to innovate in science and technology is insufficient. issues are more prominent. In recent years, the state has successively proposed the strategic development direction of building industrialization and resilient urban and rural areas, and the development of prefabricated construction methods and recoverable functional technologies has become an inevitable requirement for promoting building industrialization ...
