Assembled frame structure node friction damper

Abstract

An assembled frame structure node friction damper, the double friction plate includes a plate body and double friction plates, the double friction plate is two fan-shaped plates, and each fan-shaped plate has an arc-shaped round head slideway; the single friction plate includes The plate body and the single friction plate, the single friction plate is a fan-shaped plate, and its arc angle and plate thickness match the arc angle and spacing of the double friction plate; the rectangular plate body of the double friction plate and the single friction plate is one Axle sleeves are respectively arranged on the sides, and the two are hinged together by a connecting piece; the single friction plate is inserted between the two fan-shaped plates of the double friction plate, and is tightly connected by the connecting piece. The damper has a simple structure and low manufacturing cost. It adopts the principle of circular arc slideway and shaft rotation buffer to achieve shock absorption, which can effectively improve the energy dissipation capacity of the assembled frame structure under earthquake action. It has a wide range of applications and is easy to replace.

Description

technical field [0001] The invention relates to a friction damper, in particular to a damper applied to a node of a novel prefabricated frame structure, and belongs to the technical field of anti-seismic technology of an assembled concrete frame structure in civil engineering. Background technique [0002] my country is an earthquake-prone country, and most areas are in earthquake-resistant fortified areas. In the actual construction process, in order to slow down the vibration, more dampers are installed in the frame of the building structure. Existing dampers used on building frames are various, but most of them have complex structures and low manufacturing costs. There are also relatively simple dampers, but their working principle is mostly linear motion or circular arc plate buffer motion. In actual application, the shock absorption effect is difficult to reach the expected value. Contents of the invention [0003] The invention aims at the defects existing in the p...
