Linked energy-dissipation shock-insulation support

Abstract

The invention provides a linked energy-dissipation shock-insulation support, and belongs to the field of control over shock insulation and reduction of a building structure. An upper connection plateand a lower connection plate are arranged at the upper end and the lower end of a linked energy-dissipation shock-insulation support body respectively, the left side and the right side of the portionbetween the upper connection plate and the lower connection plate are each provided with an upper connection energy dissipation steel plate, a lower connection energy dissipation steel plate and foamed aluminum squeezing energy dissipation plates, energy-dissipation squeezing plates are connected with tension-compression rods in the middle of the support body, and an energy-dissipation filling material is arranged in a cavity in the support body. The upper connection plate and the lower connection plate drive the upper connection energy dissipation steel plates, the lower upper connection energy dissipation steel plates and end supporting energy-dissipation steel plates to be deformed for energy dissipation, energy-dissipation ribs can achieve the energy-dissipation effect, and the tension-compression rods drive the energy-dissipation squeezing plates and the energy-dissipation filling material to be squeezed and rubbed for energy dissipation, so that the foamed aluminum squeezing energy dissipation plates are squeezed for energy dissipation. The linked energy-dissipation shock-insulation support has multiple energy-dissipation effects, energy is more sufficiently dissipated, the support has a reasonable vertical initial stiffness, the requirements for vertical bearing and shock insulation of the support can be met, and the support has sufficient vertical anti-pulling ability.

Description

technical field [0001] The invention belongs to the field of shock-isolation and shock-absorbing control of building structures, in particular to a linkage energy-dissipating shock-isolation support. Background technique [0002] Bearing isolation is a passive control technology, which reduces the seismic response of the upper structure by setting an isolation device between the upper structure and the lower support system. The massive destruction and collapse of buildings in earthquakes is the direct cause of earthquake disasters. When an earthquake occurs, ground vibrations cause the seismic response of the structure. For a building structure whose foundation is fixed to the ground, its response is amplified layer by layer along the height from bottom to top. Due to the excessive seismic response (acceleration, velocity or displacement) of a certain part of the structure, the main load-bearing structure is seriously damaged or even collapsed; loss; or damage to indoor e...
