Problems solved by technology

Although some breakthroughs have been made in the study of multi-dimensional earthquakes, they are rarely applied in practice; the theory of seismic analysis of structures has reached the three-dimensional level, so the research on base isolation of structures under three-dimensional earthquakes is particularly important

Abstract

The invention discloses a pulling-resistance three-dimensional composite shock insulation support. The pulling-resistance three-dimensional composite shock insulation support sequentially comprises alower connecting plate, a horizontal shock insulation device, a lower pulling-resistance protection cylinder, a middle connecting plate, a middle pulling-resistance protection cylinder, an inner guiderod, a disc-spring shock insulation device, an outer guide cylinder, an upper connecting plate and an upper pulling-resistance protection cylinder from bottom to top. The disc-spring heat insulationdevice is composed of a disc spring set and the inner guide rod, a bearing plate sleeves the inner guide rod through a preformed hole, the outer guide cylinder sleeves the inner guide rod, a certain gap is formed in the radial direction, the outer guide cylinder is a certain height higher than the top face of the inner guide rod, and vertical displacement of the support is guaranteed. The horizontal shock insulation device is composed of a lower sealing plate, high-damping rubber, a sandwich steel plate and an upper sealing plate. Through meshing of the upper pulling-resistance protection cylinder and the middle pulling-resistance protection cylinder and meshing of the lower pulling-resistance protection cylinder and the middle connecting plate, the overall pulling-resistance function of the support is achieved. The support can reduce the horizontal and vertical seismic responses of the structure simultaneously, and has a certain pulling-resistance capability. The pulling-resistance three-dimensional composite shock insulation support has the advantages of being simple in structure, convenient to process and high in economical efficiency.

Description

Technical field [0001] The invention belongs to the technical field of basic seismic isolation of building structures, and specifically relates to a novel uplift three-dimensional composite seismic isolation support, which is used to reduce the horizontal and vertical seismic response of the building structure and has a certain uplift ability. Background technique [0002] Earthquake disasters seriously threaten the safety of human life and property. The loss of life and economic losses caused by the collapse of buildings is as high as 90%. Seismic isolation technology has become an effective means of damping, making it possible for building structures to not collapse in an earthquake. Base isolation of building structures is a commonly used seismic isolation technology. The specific method is to set up flexible connecting members between the superstructure of the building and the foundation. The energy absorption of the seismic isolation layer can effectively extend the natural v...
