Embodiment Construction

[0031] The present invention will be further described below in conjunction with the accompanying drawings.

[0032] In the first preferred version of the present invention, figure 1 The device in is expanded as figure 2 As shown, it includes a grooved upper support 1, a corresponding grooved lower support 2, and a free columnar swinging impact energy dissipation block 3 in the middle of the upper support 1 and the lower support 2 A group of two-stage tension limit auxiliary devices 4. The upper support 1 and the lower support 2 are respectively connected with the upper structure and the foundation through embedded parts, and the shock isolation device can be replaced as a whole. Such as image 3 , 4 As shown, the planes 10 and 20 of the columnar grooves on the upper and lower supports are the same as the columnar swinging impact energy dissipation block 3, and the upper and lower parts of the columnar swinging impact energy dissipation block 3 are buried in the grooves 1...

Abstract

The invention discloses a self-reset vacillation percussion energy-dissipation seismic isolation device comprising an upper support seat and a lower support seat which are oppositely arranged; the opposite surfaces of the upper support seat and the lower support seat are provided with grooves; a vacillation percussion energy-dissipation block is installed between the grooves; a group of two-stage tensioned spacing assistant device is installed between the upper support seat and the lower support seat; the vacillation percussion energy-dissipation block is unbonded with the upper support seat and the lower support seat. According to the device of the invention, seismic isolation is achieved through lifting and dropping percussion of the vacillation percussion energy-dissipation block, structural deformation is concentrated in the seismic isolation system so as to reduce or even avoid damage on a main structure. Vacillation will not occur under effect of wind load or small seisms, which satisfies normal usage of buildings. Under strong earthquakes, seismic energy can be dissipated by the vacillation and percussion of the vacillation percussion energy-dissipation block; the vacillation and percussion stop when the external effect stops and self reset is achieved under the effect of gravity. After strong earthquakes, only a group of two-stage tensioned spacing assistant device is needed to replace, which is convenient for quick restoration after the earthquakes.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a self-resetting swing impact energy-consuming shock-isolation device. Background technique [0002] Earthquakes, as sudden natural disasters, often cause huge social impact and economic losses. China is a country severely affected by earthquakes, with high frequency of earthquakes, strong earthquakes with shallow focus and wide distribution. The casualties and direct economic losses caused by earthquakes in our country are huge every year. [0003] Ordinary concrete buildings designed according to codes can no longer fully meet the growing seismic demand of buildings. The structure needs to be under the action of earthquakes and other disasters without excessive damage to the structure, and after the disaster can be repaired under reasonable technical and economic conditions to restore its expected function, that is, the damage controllable structure. [0004] Struc...
