Problems solved by technology

[0003] However, most metal dampers have a single energy consumption method, which cannot meet the needs of buildings under different earthquake levels, and most of the dampers are disposable consumables. After the energy-consuming parts are damaged, the energy-dissipating capacity of the damper will be reduced or even invalidated. recycle again

Embodiment Construction

[0015] The technical solution of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0016] Such as figure 1 and figure 2 As shown, the friction-shear combined type repairable metal damper of the present invention includes a guide rod connection part 7 connected with a building structure and a symmetrical setting on it that prevents the damping from being connected to the guide rod connection part 7. The sliding guide rod 1 is composed of the connecting part 8 of the energy-consuming part of the limit displacement protection plate 13 for device failure, and the protective shell 2 sleeved on the sliding guide rod 1 . The protective case 2 comprises an upper protective case 9 arranged in parallel, a lower protective case 10 and a protective case connecting portion 11 connected with the building structure, such as image 3 shown.

[0017] The left and right sides of the sliding guide rod 1 are provided with a fricti...

Abstract

The invention discloses a friction and shear combined type repairable metal damper which comprises a sliding guide rod and a protective shell arranged on the sliding guide rod in a sleeving mode. A friction board is arranged on the side face of the sliding guide rod, a plurality of sawteeth arranged in the vertical direction of the friction board are arranged on the friction board, a cover board is arranged on the side face of the protective shell, sawteeth meshed with the sawteeth of the friction board are arranged on the cover board, and a plurality of low-yield-point steel sheets are arranged between the protective shell and the sliding guide rod. The friction and shear combined type repairable metal damper has a good energy consumption effect, can achieve staged yield energy consumption, and is convenient to disassemble and high in repairability.

Description

technical field [0001] The invention belongs to the field of metal dampers, in particular to a repairable metal damper of friction and shear combination type. Background technique [0002] Adding dampers in the building structure can effectively reduce the impact of earthquake loads and wind loads on the safety of the main structure, and improve the building's ability to withstand strong earthquakes. Due to its good hysteretic energy consumption characteristics and stable performance, metal dampers can consume a large amount of ground vibration or wind vibration energy, thereby reducing the damage of buildings under various horizontal loads, and can effectively reduce earthquake or wind vibration. The loss of life and property caused by vibration is regarded as the first line of defense of the building structure. Research and development of new materials and design of new energy consumption methods have become the main direction of the development of metal dampers. [0003...
