Abstract

The invention relates to a multi-pyramid surface friction shock-isolation bearing and a shock-isolation system. The polygonal pyramid surface friction shock-isolation support includes: an upper deck, a middle structure and a lower structure; a groove in the shape of a polygonal pyramid is arranged on the lower structure to form a sliding concave surface of the polygonal pyramid; the middle structure includes a A flat plate, the lower surface of the flat plate is provided with a convex column, and the lower end of the convex column is a polygonal pyramid sliding convex surface matching the shape of the polygonal pyramid sliding concave surface, so that the convex column can slide in the groove; the upper surface of the flat plate is provided with a circular snap ring; The bottom of the upper card seat is matched with the snap ring through the card slot, so that the upper card seat can rotate relative to the middle structure. The vibration isolation system also includes a cross vertical anti-lift-off limiting device. The seismic isolation support provided by the present invention avoids the problem of resonance, does not cause the slider to fall off, and ensures that sufficient vertical load can be provided under any circumstances; A bit device prevents the building from toppling over.

Description

technical field [0001] The invention relates to the technical field of engineering shock isolation, in particular to a multi-pyramid frictional shock-isolation bearing and a shock-isolation system. Background technique [0002] In order to alleviate earthquake disasters, reduce economic losses and casualties, it is necessary to consider the degree of earthquake risk that the project construction site may encounter during project construction, and add necessary seismic isolation design to buildings. [0003] Zayas of the University of California, Berkeley proposed the friction pendulum isolation technology (Friction Pendulum System, referred to as FPS). As shown in Figure 1(a), the FPS includes three parts: the upper device, the center slider and the lower sliding spherical concave surface. When an earthquake occurs, the center slider can slide in the spherical concave surface, thereby isolating the seismic energy. [0004] On the basis of FPS, Constantinou proposed a triple...
