Embodiment Construction
[0044] The rotary tube type damper proposed by the invention can be installed between the structural frames of the building to provide certain rigidity and energy dissipation capacity for the building.
[0045] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0046] Figure 1a-Figure 1e It is the first embodiment of the present invention. It consists of an energy-dissipating circular tube 1, a left joint 31 provided at one end of the energy-dissipating circular tube 1, and a right joint 32 provided at the other end. There are a plurality of long holes 2 inclined relative to the diameter of the pipe. The long holes 2 have two circles, which are symmetrical to each other. Between the rotating section 13 of the energy-dissipating round pipe 1 , between a circle of long holes 2 at the left end and the left joint 31 , and between a circle of long holes 2 at the right end and the right joint 32 , are the connecting sec...

The invention provides a rotary pipe type damper and belongs to the field of energy elimination and vibration absorption of a building structure. The rotary pipe type damper comprises an energy-consuming circular pipe; a plurality of long holes which are inclined along an axial direction of the circular pipe are formed in a pipe wall of the energy-consuming circular pipe along an annular direction; an energy-consuming section of the energy-consuming circular pipe is formed by annular parts of the long holes; the energy-consuming circular pipe is internally provided with an inner sleeve and / or is externally provided with an outer sleeve; meanwhile, an energy-consuming material is arranged between a rotation section of the energy-consuming circular pipe and the sleeve; when the energy-consuming circular pipe is stretched or shortened, the energy-consuming material can be yielded; the energy-consuming material between the energy-consuming circular pipe and the sleeve can be subjected to phase movement deformation or movement, energy can be consumed and the vibration of a structure connected with the energy-consuming circular pipe is further reduced; and according to the rotary pipe type damper, the disadvantages that the existing rotary pipe type damper movement conversion device (screw rod) has a complicated structure and does not consume the energy are overcome; and the energy-consuming section can amplify the axial displacement of the energy-consuming circular pipe, can also consume the energy and has a simple structure.
Description
technical field [0001] The invention relates to a damper used for energy dissipation and shock absorption of building structures, in particular to a rotary tube damper. Background technique [0002] Structural energy dissipation and shock absorption is to add dampers to the building structure to consume the seismic energy input into the structure, thereby reducing the seismic response of the structure. Dampers are also called energy dissipation devices, including viscous dampers, hysteretic dampers and friction dampers. Because the building structure generally does not allow large inter-story deformations, in order to effectively exert the energy dissipation effect of the damper, an amplifying device is often required to amplify the inter-story deformation of the building structure. These magnifying devices include toggle supports, scissor supports, etc. In particular, the 1998 Japanese patent (publication number: JP-10-184757) discloses a rotary cylinder damper, which con...
