Embodiment 1

[0017] The frame 1 is an isosceles trapezoidal structure, the slope of the left leg 5 and the right leg 6 is 85°, and the two upper sides of the support member 7 are connected to the node where the upper beam 3 of the frame is connected to the left and right legs, Two of the lower sides are connected on the lower beam 4 of the frame. The support member 7 is braced with constrained buckling. The damper 2 is bolted to the support member 7 , and the support member 7 is welded to the frame 1 .

[0018] The center of the damper 2 coincides with the center of the frame 1 to ensure that the four support members 7 are on the same straight line as the corresponding diagonals of the damper 2 .

Embodiment 2

[0020] The frame 1 is an isosceles trapezoidal structure, the slope of the left outrigger 5 and the right outrigger 6 is 60°, and the four supporting members 7 are connected to the joints connecting the upper beam 3 and the lower beam 4 of the frame with the left and right outriggers . The support member 7 is braced with constrained buckling. The damper 2 is bolted to the support member 7 , and the support member 7 is riveted to the frame 1 .

[0021] The center of the damper 2 coincides with the center of the frame 1 to ensure that the upper two support members 7 are on the same line as the diagonals of the frame 1 .

Embodiment 3

[0023] The frame 1 is an isosceles trapezoidal structure, and the slope of the left outrigger 5 and the right outrigger 6 is 40°. The support members 7 are respectively connected to the upper beam 3 and the lower beam 4 of the frame. The support member 7 is braced with constrained buckling. The damper 2 is bolted to the support member 7 , and the support member 7 is bolted to the frame 1 .

Abstract

The invention relates to a protective device of a building, in particular to a protective device for reducing the external vibration effects. An energy-dissipating and shock-absorbing supporting device comprises a quadrilateral framework and a damper arranged in the framework, the damper is connected with the framework through a supporting member, the framework comprises an upper beam, a lower beam, a left supporting leg and a right supporting leg, and the framework is of a trapezoidal structure. The energy-dissipating and shock-absorbing supporting device has convenient installation and dismounting, strong energy-dissipating capacity and wide shockproof and quake-proof application fields.

Description

technical field [0001] The invention relates to a protective device for buildings, in particular to a protective device for reducing the impact of external vibrations. Background technique [0002] The traditional seismic design of civil engineering structures uses the elastic-plastic deformation of structural components to consume seismic energy and achieve the purpose of mitigating earthquake effects. However, the elastic-plastic energy dissipation of structural components will inevitably cause damage to the structure, even irreparable damage. The major earthquakes that occurred in recent years (such as Northridge in the United States in 1994, Kobe in Japan in 1995, Jiji in Taiwan in 1999, and Wenchuan in China in 2008) have caused serious structural damage and major property losses. This defect of the traditional seismic design method has been exposed. . [0003] The energy dissipation and vibration reduction technology greatly reduces the deformation and damage of the s...
