Three-dimensional shock-absorption vibration-isolation supporting seat for building

Abstract

The invention relates to the technical field of building vibration isolation, in particular to a three-dimensional shock-absorption vibration-isolation supporting seat for a building. The three-dimensional shock-absorption vibration-isolation supporting seat comprises vertical vibration-isolation supporting seats, a horizontal vibration-isolation supporting seat overlaid with the vertical vibration-isolation supporting seat, and horizontal shock-absorption devices, wherein the vertical vibration-isolation supporting seats and the horizontal vibration-isolation supporting seat are all arrangedbetween an underground foundation and a stand column; the horizontal shock-absorption devices are connected to the side surface of the stand column; and the horizontal shock-absorption devices are used for consuming horizontal vibration energy on the stand column. According to the three-dimensional shock-absorption vibration-isolation supporting seat for the building, the horizontal shock-absorption devices are arranged around the stand column, the horizontal vibration energy is consumed from the periphery of the stand column, so that the consumption capacity of the horizontal vibration energyis increased, a possibility that the three-dimensional shock-absorption vibration-isolation supporting seat for the building is damaged is reduced, and therefore, a safety risk of the building abovea three-dimensional vibration-isolation is reduced.

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
