Embodiment Construction

[0022] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0023] see figure 1 , which shows an example of the composition of the double-rod friction damper given in this example.

[0024] It can be seen from the figure that the double-rod friction damper is mainly composed of an outer sleeve 1, a sliding shaft 6, a friction slider 3, an extrusion ring 2 and a limit spring 7 in cooperation with each other.

[0025] Wherein, the outer sleeve 1 constitutes the main body of the entire friction damper, which is a cylindrical structure with a cavity inside as a whole, and is preferably cylindrical in this example, which is convenient for installation and setting. Furthermore, both ends of the outer sleeve 1 have end plates 11 , and through holes for the sliding shaft 6 to pass through are symmetrically form...

Abstract

The invention discloses a double-outlet-rod type friction damper. The friction damper is characterized in that a sliding shaft is movably arranged in an outer sleeve in a penetrating mode, the two ends of the sliding shaft extend out of the two ends of the outer sleeve, and the surface of the sliding shaft is a friction face with a certain friction system; a plurality of friction sliding blocks are distributed in the circumferential direction of the sliding shaft, and the friction base face of each friction sliding block is in sliding friction fit with the surface of the sliding shaft; extrusion rings sleeve the two ends of a plurality of friction sliding blocks distributed in the circumferential direction of the sliding shaft, the inner surface of each extrusion ring is in synchronous contact fit with the arc slopes on the plurality of friction sliding blocks, and the outer surface of each extrusion ring is in contact fit with the inner wall of the outer sleeve; and limiting springs are arranged relative to the extrusion rings, and pre-pressure facing the friction sliding blocks is formed on the extrusion rings. The friction damper capable of sliding bidirectionally can replace aconventional friction damper, and can be used in flexible connection, such as a cable of a cable structure.

Description

technical field [0001] The invention relates to a building shock absorption scheme, in particular to a damper. Background technique [0002] At present, the dampers mainly include metal dampers, viscous dampers, viscoelastic dampers and friction dampers. Among them, the friction damper is widely used because of its simple principle, convenient structure and low price. The friction damper is an energy-consuming shock-absorbing device that uses the friction of the friction surface to dissipate the vibration energy. The conventional friction damper is used in the connection of rigid components, and the frictional energy of the friction surface of the damper is driven by the movement of the rigid rod. When it is a flexible structure or a flexible connection, conventional dampers are not suitable. [0003] The interstory deformation of the building under the action of earthquake or wind load is small, generally 5mm-40mm, and the maximum stroke of the damper can generally reach...
