Abstract

The invention discloses an arc friction type damper for reinforcing a beam-column joint. The arc friction type damper for reinforcing the beam-column joint comprises at least one friction damping device, a first connection plate and a second connection plate, wherein the first connection plate and the second connection plate are arc. One end of the first connection plate and one end of the secondconnection plate are used for being fixedly connected with the corresponding beam or column correspondingly. The arc faces of the other ends of the first connection plate and the second connection plate are attached to each other to form an overlapping section. The overlapping section is provided with the friction damping device. The friction damping device comprises a plate body, a friction plateand a friction sheet. The plate body is fixedly connected with the first connection plate through a second connection piece. The plate body is fixedly connected with the friction plate through a first connection piece. The side, away from the plate body, of the friction plate is provided with a groove. The friction sheet is clamped into the groove and is in contact connection with the second connection plate. The arc friction type damper for reinforcing the beam-column joint reduces plastic deformation at the beam-column joint, the friction sheet can be conveniently replaced, operation is easy, and the arc friction type damper for reinforcing the beam-column joint is wide in application range, does not occupy too much use space and is low in cost, high in practicability and worthy of popularization.

Description

technical field [0001] The invention belongs to the technical field of energy dissipation and shock absorption, in particular to the technical field of damper equipment, in particular to an arc-shaped friction damper for reinforcing beam-column nodes. Background technique [0002] At present, the methods of strengthening beam-column joints all have good strengthening effect, but under the action of earthquake, there are still some defects. For example, it is convenient to improve the seismic capacity of the component by increasing the size of the original component, but this method is limited to improve the ductility of the structural component; the metal damper is convenient for construction and simple in structure, and can better improve the seismic performance of the beam-column joint, but The application of the energy dissipation mechanism is single, and in rare earthquakes, after the damping component is damaged, the process of replacing the damping component is cumbers...
