Adjustable coupling beam joint seismic energy dissipating device and seismic coupling beam joint

Abstract

The invention provides an adjustable coupling beam joint seismic energy dissipating device and a seismic coupling beam joint. The energy dissipating device comprises acorbel bracket and an energy dissipating piece. The corbel bracket is used for being matched with and installed on a steel column of the coupling beam joint. The corbel bracket comprises a plurality of inserting slots which are parallel to the steel column and formed at intervals. The energy dissipating part comprises a plurality of energy dissipating plates arranged side by side at intervalsand atop plate arranged at the top ends of the energy dissipating plates. The energy dissipating plates are correspondingly arranged in the inserting slots in a clamped mode. The lower part of each energy dissipating plate is inserted into the corresponding inserting slot. Each energy dissipating plate is provided with an enlarged energy dissipating part which is exposed to the exterior of the corresponding inserting slot. The top plate isused for being matched with and installed on the lower portion of a steel beam of the coupling beam joint. The time point of entering into a plastic energy dissipating state of the enlarged energy dissipating part is controlled by adjusting the slot width of the inserting slots. The adjustable coupling beam joint seismic energy dissipating device solves the problems that the energy dissipating performance of an existing seismic energy dissipating device is general, and repairing after the earthquake is difficult, and the performance and disassembly work of the energy dissipating device are further improved.

Description

technical field [0001] The invention belongs to the technical field of anti-seismic structures, and relates to an anti-seismic energy-consuming device for an adjustable coupling beam joint and an anti-seismic coupling beam joint. Background technique [0002] A recoverable functional structure refers to an earthquake-resistant structure that can restore its function without repair or a little repair after an earthquake. This structure can not only protect people's lives and property during an earthquake, but also help people survive after an earthquake Resuming normal life as soon as possible is a hot topic in the current seismic design of structures. [0003] At present, the commonly used anti-seismic energy dissipation devices installed on the joints of steel structures are mainly welded T-shaped joint plates, angle steel, and friction dampers. However, the energy dissipation performance of this type of anti-seismic energy dissipation devices is average and it is difficult...
