Description

Technical Field

[0001] The present invention relates to the field of vibration prevention technology, and in particular to a plurality of series-parallel thick-walled rubber bearings and a three-dimensional friction pendulum bearing. Background Art

[0002] In recent years, rail transit has developed rapidly in major cities with its convenient and fast travel experience. The TOD property development model oriented towards rail transit has developed rapidly in major cities across the country. Properties above rail transit have very high economic value, and development efforts are focused on developing subway properties. In low-intensity fortification areas, due to the vertical vibration and noise caused by rail transit, general seismic isolation bearings cannot effectively isolate the building, resulting in a decrease in the comfort level of the building and even the normal use of some buildings. In order to solve the vertical vibration caused by rail transit, it is urgent to develop some seismic isolation products for these vibrations. Existing seismic isolation bearings usually use coil steel springs as vertical vibration isolation units, but coil steel spring bearings are expensive and have large dimensions, and when vibration reduction is required, dampers usually need to be added. In addition, in high-intensity fortification areas, properties above rail transit are affected by both rail transit vibration and potential seismic motion. Summary of the Invention

The thick laminated rubber bearing 12 is wrapped around a guide rod 161. The guide rod 161 is connected to the lower sleeve 151 and is provided in the upper sleeve 111.
