Self-resetting rigidity self-adaptive control assembly type beam-column joint

Abstract

The invention discloses a self-resetting rigidity self-adaptive control assembly type beam-column joint. A prefabricated column (1) and a prefabricated beam (2) are connected in a hinged mode througha column T-shaped connecting plate (6), a beam T-shaped connecting plate (7) and a hinge pin (11), a saddle-shaped circular plate (8) and a rubber circular plate (9) which can achieve variable rigidity are installed between a first lug plate (6-2) of the column T-shaped connecting plate and a second lug plate (7-2) of the beam T-shaped connecting plate, and a high-elasticity piece (13) is tensioned, fixed and bolted between U-shaped clamping grooves (12) of a first vertical plate (6-1) of the column T-shaped connecting plate and U-shaped clamping grooves (12) of a second vertical plate (7-1) of the beam T-shaped connecting plate through a clamp (14). According to the self-resetting rigidity self-adaptive control assembly type beam-column joint, self-adaptive control over the structure under the action of external loads of different strengths is achieved, large plastic damage to components is avoided, meanwhile, complete reset can be basically achieved after an earthquake, dry operationconstruction of the whole joint is achieved, connection is reliable, installation is convenient, and rapid replacement can be achieved.

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] The traditional cast-in-place reinforced concrete structure requires a lot of labor force, high resource consumption, and great environmental impact. Its development model does not meet the current social needs of sustainable development. With the transformation of the national development strategy, the prefabricated concrete structure, as an industrialized building production mode, has attracted widespread attention due to its advantages of less labor demand, low resource consumption, low environmental pollution, high component quality, and short construction period. Relevant government departments Policy documents to promote the industrialization of construction have been issued many times, clearly requiring the vigorous development of prefabricated buildings. [0003] The node connect...

AI Technical Summary

Problems solved by technology

However, the current research focuses on enhancing the seismic performance of the joint itself, while the research on the adaptive control technology of the whole structure under the action of external loads of different strengths is relatively insufficient. The difficulty is relatively large, and it is difficult to achieve rapid recovery of building functions
