A new type of three-dimensional shock-isolation bearing

Abstract

The invention relates to the technical fields of construction engineering and bridge engineering, in particular to a novel three-dimensional shock-isolation bearing with relatively large initial vertical static stiffness for building shock-isolation layers, bridge shock-isolation layers and equipment shock-isolation layers, which is easy to manufacture , construction, installation and maintenance are convenient; the horizontal and vertical shock absorption are decoupled from each other and are not involved in each other. The rotating rubber bearing assembly is used, which has a small vertical stiffness during vertical movement, thereby prolonging the vertical cycle of the superstructure. Reduce the earthquake effect; because the internal rubber is a high damping support, it has the function of energy dissipation, so that the vertical earthquake effect can be further reduced through energy dissipation, ensuring the safety of the upper structure. When the pin is set, the support is vertically static It has a large initial vertical static stiffness under load.

Description

technical field [0001] The invention relates to the technical fields of construction engineering and bridge engineering, in particular to a novel three-dimensional shock-isolation bearing with relatively large initial vertical static stiffness used for building shock-isolation floors, bridge shock-isolation floors and equipment shock-isolation floors. 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...

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. From the seismic records measured by previous major earthquakes, the vertical earthquake occupies a lot of weight in the entire seismic energy. How to solve the problem of vertical vibration? Seismic isolation has always been a major problem plaguing the entire seismic isolation field, especially for some particularly important buildings, bridges and important equipment and equipment
