A three-dimensional seismic isolation device with tensile function

Abstract

The invention relates to the technical field of seismic isolation for buildings and bridge engineering, in particular to a three-dimensional seismic isolation device with tensile function, which includes a top steel platform, a horizontal seismic isolation support, a vertical tensile component, a transitional steel platform, a vertical isolation seismic component, the horizontal seismic isolation support is respectively connected to the bottom of the top steel platform and the top of the transitional steel platform, the vertical seismic isolation component is arranged at the bottom of the transitional steel platform, and the vertical tensile component is sleeved on The outer circumference of the horizontal shock-isolation support is connected to the bottom of the top steel platform and the top of the transitional steel platform respectively, not only can play a good shock-isolation function in the horizontal direction and vertical direction, but also has a good shock-isolation function in the horizontal and vertical Mutual decoupling, no involvement with each other, high safety; the vertical tensile member provides a relatively large tensile strength without hindering the movement of the horizontal and vertical shock-isolating members. The bearing being pulled out provides a higher safety reserve.

Description

technical field [0001] The invention relates to the technical field of seismic isolation of buildings and bridge engineering, in particular to a three-dimensional seismic isolation device with a tensile function. Background technique [0002] Laminated rubber isolation technology plays an important role in reducing the damage caused by horizontal earthquakes to buildings and bridge structures. It has good horizontal deformation capacity and energy dissipation effect, so it can effectively isolate buildings and bridges when used in isolation layers. The damage to buildings and bridges caused by the horizontal vibration of earthquake resistance has been well tested in many actual earthquakes in recent years. However, the disadvantage of the laminated rubber isolation bearing is that it does not have the function of shock absorption in the vertical direction, and the vertical tensile strength is small. From the seismic records measured in previous major earthquakes, the vertica...

Problems solved by technology

However, the disadvantage of the laminated rubber isolation bearing is that it does not have the function of shock absorption in the vertical direction, and the vertical tensile strength is small. From the seismic records measured in previous major earthquakes, the vertical earthquake occupies a large proportion of the entire seismic energy. How to solve the vertical seismic isolation has always been a major problem that plagues the entire seismic isolation industry, especially for some very important buildings, bridges and important equipment and equipment, and for high-rise seismic isolation buildings with large height-to-width ratios, How to enhance the tensile capacity of the seismic isolation bearing is also a difficult problem
