A three-dimensional shock-absorbing vibration-isolation bearing for a building

Abstract

The present invention relates to the technical field of building shock isolation, in particular to a three-dimensional shock-absorbing and vibration-isolating support for a building, which includes a vertical vibration-isolating support, a horizontal shock-isolating support stacked on the vertical vibration-isolating support, and Horizontal damping device; the vertical vibration isolation bearing and the horizontal vibration isolation bearing are both arranged between the underground foundation and the column; the horizontal vibration damping device is connected to the side of the column, and the horizontal vibration isolation The device is used to dissipate the horizontal vibration energy on the column. The three-dimensional shock-absorbing and vibration-isolation support for buildings described in the present invention consumes horizontal vibration energy from the surroundings of the column by arranging the horizontal shock-absorbing device around the column, thereby increasing the consumption capacity of horizontal vibration energy, The damage possibility of the three-dimensional shock-absorbing and vibration-isolation support of the building is reduced, thereby reducing the safety risk of the building above the three-dimensional shock-isolation device.

Description

technical field [0001] The invention relates to the technical field of building shock isolation, in particular to a three-dimensional building shock-absorbing vibration-isolation support. Background technique [0002] In building structures, it is usually necessary to use shock-absorbing and vibration-isolating devices, which are isolation devices installed between the building and the foundation to block vibration and vibration. With the emergence of more and more railway superstructure models under which rail traffic passes, the vehicle-induced vibration isolation caused by trains and the shock absorption during sudden earthquake disasters have become the key factors for the comfort and safety of railway superstructures. Important influencing factors. In this context, the existing known vibration sources such as: the vibration generated when the train passes the railway around the building, this type of vibration is mainly vertical vibration; the existing known vibration s...

Problems solved by technology

With the improvement of people's understanding of the multi-dimensional characteristics of earthquakes and vibration, there is a strong demand for shock-absorbing and vibration-isolating devices with horizontal and vertical vibration isolation. The existing three-dimensional shock-absorbing and vibration-isolating devices are made of laminated rubber The seismic isolation bearing and the existing vertical vibration isolation bearing are used to consume the horizontal vibration energy of the earthquake and the vertical vibration energy brought by the environment, which can meet the vibration isolation requirements of building structures in most areas, but The horizontal vibration isolation capability of this three-dimensional shock-absorbing and vibration-isolating device is limited. When a strong earthquake (magnitude greater than or equal to 6 earthquakes) occurs, it is difficult to exhaust the horizontal vibration energy, which may damage the entire three-dimensional vibration-isolation device. This in turn poses a safety risk to buildings above the 3D seismic isolation device
