Novel three-dimensional shock isolation device with tensile function

Abstract

The invention relates to the technical field of shock isolation in building and bridge engineering, in particular to a novel three-dimensional shock isolation device with a tensile function. The novel three-dimensional shock isolation device comprises a top steel platform, a horizontal shock isolation stand, a vertical tensile component, a transition steel platform and a vertical shock isolation component. The horizontal shock isolation stand is connected with the bottom of the top steel platform and the top of the transition steel platform, the vertical shock isolation component is arranged at the bottom of the transition steel platform, the vertical tensile component is arranged on the periphery of the horizontal shock isolation stand in a sleeving mode and connected with the bottom of the top steel platform and the top of the transition steel platform, so the good shock isolation function can be achieved in both the horizontal direction and the vertical direction, the horizontal shock isolation function and the vertical shock isolation function are decoupled without interfering with each other, and safety is high. On the premise that the vertical tensile component does not interrupt the movement of a horizontal shock isolation component or the movement of the vertical shock isolation component, large tensile strength is provided, and high safety stock is provided for preventing the structure from being pulled to be damaged by the stand.

Description

technical field [0001] The invention relates to the technical field of seismic isolation for buildings and bridge engineering, in particular to a novel 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 ...

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
