Embodiment 1

[0074] The method of Embodiment 1 is: when the first structure and the second structure are from the equilibrium position to any point far away, only one group of damping units is active, and the pressure between the friction plate and the rotating friction energy dissipation disk is gradually Increase to increase the damping effect.

[0075] When the first structure and the second structure return to the equilibrium position from any far away point, only one set of damping units is active, and the pressure between the friction plate and the rotating friction energy dissipation disc is gradually reduced to reduce damping Effect.

Abstract

The invention relates to a variable-damping friction type damper, a working method and a prefabricated building. When a first structure and a second structure reach an any point away from an equilibrium position, from the equilibrium position, only a set of damping units act, and pressure between a friction plate and a pivoting friction energy consumption disk is gradually enlarged to increase damping effects. When the first structure and the second structure return to the equilibrium position from any point away from the equilibrium position, only a set of the damping unit act, and the pressure between the friction plate and the pivoting friction energy consumption disk is gradually reduced to reduce damping effects.

Description

technical field [0001] The invention relates to the field of prefabricated building structures and dampers, in particular to a variable damping friction damper, a working method and a prefabricated building. Background technique [0002] CN 109372141 A discloses a variable damping viscoelastic plate damper, which includes outer steel plates arranged up and down oppositely and a middle steel plate located between the two outer steel plates. The outer steel plates are provided with a plurality of square hole structures along the horizontal direction; For the damping units set, each group of damping units is symmetrically distributed on the upper and lower sides of the middle steel plate with the middle steel plate as the axis of symmetry, and each group of damping units is glued to the middle steel plate; wherein, the first group of damping units is glued with The connecting plate is fixedly connected with the outer steel plate; the other groups of damping units are glued with...
