Problems solved by technology

However, the surface pressure of the traditional friction damper is very high, and the material of the friction pair is severely worn after repeated friction, resulting in a significant drop in output force
In addition, these dampers need to be installed in specific positions of the structure, which is not conducive to the division of building functions

Embodiment 1

[0021] figure 1 , figure 2 It is the specific structure schematic diagram of this embodiment. The present embodiment is made up of friction plate 1, swing arm 2, lightweight wall body 3, pull bolt 4, hinge shaft 5, chute shaft 6, connecting plate 7, upper beam 8, and lower beam 9. The lower beam 9 and the upper beam 8 can be made of channel steel or I-beam, and are firmly connected to the roof and floor of the structure. The connecting plate 7 is welded on the upper crossbeam 8 and is a member of the connecting structure and the friction pendulum. In actual operation, the connecting plate 7 and the upper crossbeam 8 can also be combined into one. The friction pendulum is composed of a swing arm 2 and a friction plate 1, connected together with a connecting plate 7 through a hinge shaft 5, and can freely rotate around the hinge shaft. A rectangular chute is opened on the swing arm 2, and the chute shaft 6 is fixed on the light wall 3, and the swing arm 2 transmits horizonta...

Abstract

The invention relates to a pendulum type friction wall. The friction wall is used for energy dissipation of house buildings. The pendulum type friction wall comprises upper and lower beams, a pair of connection plates, a friction pendulum, a pair of lightweight walls, a hinge axis, a chute and split bolts. The friction wall has the following beneficial effects: the friction wall can be installed in the structure as a segmentation element with building functions and does not bear vertical load; under the action of wind load or seismic load, the energy input by the wind load or seismic load is dissipated by friction generated when the friction pendulum swings, thus protecting the main members of the structure; and the friction force can be increased through leverage of a swing arm, and lower pressure can be maintained on the friction surface, thus reducing abrasion of the friction pair.

Description

(1) Technical field [0001] The invention belongs to the field of anti-seismic technology of structural engineering, and relates to a wall damper which uses a friction mechanism to dissipate vibration energy. (2) Background technology [0002] Modern civil engineering structures often use some mechanical devices to dissipate the energy introduced by wind vibration and earthquake action, so as to achieve the purpose of protecting the main load-bearing components, which is the concept of structural control. At present, the research and application of structural control are mainly divided into passive control, semi-active control, active control and hybrid control. Among them, passive control technology is widely used in engineering construction because of its simple and reliable structure, stable energy consumption performance, low price, and convenient maintenance, or it is used to improve the seismic or wind resistance of existing old buildings. The passive energy dissipatio...
