Abstract

The invention discloses a shock absorption and shock insulation support for a building. The shock absorption and shock insulation support comprises an upper connecting plate, rubber bands, a pluralityof middle partition plates, lead core columns, a friction body and a lower connecting plate. The lead core columns are vertically arranged, the upper connecting plate is arranged at the upper ends ofthe lead core columns, the lower connecting plate is arranged at the lower ends of the lead core columns, and the friction body is arranged between the lower connecting plate and the lead core columns. The middle partition plates are fixedly arranged on column bodies of the lead core columns at equal intervals in a sleeving mode. The rubber bands are wound from inside to outside on the lead corecolumns between adjacent middle partition plates. The shock absorption and shock insulation support ensures that under the action of earthquake, the friction between the high damping friction body onthe lower portion and the lead core columns consumes energy and provides isolation performance for an upper structure, and under the action of gravity or human, the friction body has a good self-resetability.

Description

Technical field [0001] The invention belongs to the field of building structure foundations, and particularly relates to a shock-absorbing and isolating support for buildings. Background technique [0002] With the development of modern housing construction, the proportion of shock absorption and vibration isolation technology in housing construction is increasing. When an earthquake disaster occurs, how to ensure that the building is "not damaged by small earthquakes, repairable by moderate earthquakes, and not collapsed by large earthquakes" has always troubled designers; the use of shock-absorbing and isolating bearings is a practical method of shock-absorbing It is also an effective technology to reduce the hazard of earthquakes. [0003] Its seismic isolation technology mainly reduces the seismic response of buildings by absorbing or dissipating seismic energy. The commonly used vibration isolation bearings mainly include rubber isolation bearings and friction isolation bear...
