Anti-seismic and wind-resistant device with hole site self-adaptive capacity and replacement method

Abstract

The invention discloses an anti-seismic and wind-resistant device with hole site self-adaptive capacity and a replacement method. The anti-seismic and wind-resistant device comprises an anti-seismic support assembly and an additional assembly, wherein the anti-seismic support assembly comprises a lower connecting steel plate, an energy dissipation seat arranged at the top of the lower connecting steel plate and an upper connecting steel plate arranged at the top of the energy dissipation seat; and the additional assembly is arranged between the lower connecting steel plate and the upper connecting steel plate and comprises a connecting flange arranged at the top of the lower connecting steel plate, an annular gap formed in the middle of the connecting flange, a connecting ring arranged in the annular gap and a connecting piece arranged at the top of the connecting ring. The anti-seismic and wind-resistant effects of the anti-seismic support assembly in the using process are improved through the arrangement of the additional assembly, the additional assembly is arranged to be in a split type, the operation convenience and the using stability of the additional assembly are greatly improved, and meanwhile, the application range of the device is widened through the arrangement of the annular gap, so that the device is more convenient to operate after construction or earthquakes.

Description

technical field [0001] The invention relates to the technical field of shock absorption and isolation of buildings and bridge structures, in particular to an anti-seismic and wind-resistant device with hole position self-adaptive capability and a replacement method. Background technique [0002] Earthquakes are one of the natural disasters that pose a serious threat to human life and property safety. How to reduce human losses as much as possible when encountering earthquakes has become the direction of scientists' efforts; shock absorption and isolation technology has become the field of earthquake engineering in the past forty years. It is the most effective way for humans to greatly improve earthquake safety and prevent earthquake damage. Usually, ordinary rubber isolation bearings have limited anti-seismic functions and no wind resistance functions.

[0002] Earthquakes are one of the natural disasters that pose a serious threat to human life and property safety. How to reduce human losses as much as possible when encountering earthquakes has become the direction of scientists' efforts; shock absorption and isolation technology has become the field of earthquake engineering in the past forty years. It is the most effective way for humans to greatly improve earthquake safety and prevent earthquake damage. Usually, ordinary rubber isolation bearings have limited anti-seismic functions and no wind resistance functions. Under the action of wind or other large external forces The bottom is prone to displacement, so it will have a great impact on the stability of the superstructure. The additional functional devices in the prior art are generally integrated, and then fixed on the seismic support by welding or other methods, regardless of Whether it is after construction or after an earthquake, there will be a certain displacement difference between the upper and lower parts of the seismic bearing. Due to the influence of the displacement difference, the installation hole position of the original additional device is extremely difficult to install and replace, and the operation cost is high, which will affect the subsequent earthquake resistance.
