Rotary friction energy dissipater with flanges for beam-column joint connection

Abstract

The invention relates to the field of seismic resistance and energy consumption of building structures, in particular to a flange-provided rotational friction energy dissipater for beam-column joint connection, which is characterized by comprising a first connecting component, a second connecting component, a front channel steel splicing piece, a rear channel steel splicing piece and a plurality of high-strength friction type bolts, the first connecting part is formed by welding a first connecting end plate, a first web plate, an upper flange and a lower flange; the second connecting part is formed by welding a second connecting end plate, a second web plate, an upper flange and a lower flange; the right sides of the front channel steel splicing piece and the rear channel steel splicing piece are fixedly mounted with the second connecting part, and the left sides are mounted with the first connecting part in a friction swinging manner; the inner side friction faces of the front channel steel splicing piece and the rear channel steel splicing piece are subjected to sand blasting treatment or covered with steel-brass sheets, meanwhile, the first web is a pure exposed steel component, under the earthquake action, earthquake input energy is dissipated, and the energy dissipater can effectively transmit beam end bending moment without losing flexural bearing capacity.

Description

technical field [0001] The invention relates to the field of anti-seismic energy dissipation of building structures, in particular to a flanged rotating friction energy dissipation device used for beam-column joint connection. Background technique [0002] In recent years, my country's demographic dividend is gradually disappearing, and the continuous rise in labor costs has also made the phenomenon of "labor shortage" in the construction industry frequent; Some common problems such as more waste production. In order to promote the sustainable development of the construction industry and continue to improve environmental protection and energy conservation, the state and society have paid more and more attention to the industrialization of construction, especially the prefabricated concrete structure system. Governments at all levels have also successively formulated and issued a series of policies and measures to promote the development of construction industrialization. [...

Problems solved by technology

[0002] In recent years, my country's demographic dividend is gradually disappearing, and the continuous rise in labor costs has also led to frequent "labor shortages" in the construction industry; in addition, traditional on-site construction methods have serious environmental pollution and water resource waste, poor engineering quality and poor construction quality. Some common problems such as excessive garbage output
