Abstract

The invention relates to a multifunctional dual-curved-surface spherical shock-absorbing and shock isolation support. A lower support plate, a middle support plate and an upper support plate are arranged on the multifunctional dual-curved-surface spherical shock-absorbing and shock isolation support, wherein limiting plates are arranged on four sides of the upper part of the lower support plate; embedded circular rings are arranged at the outer parts of slipping concave spherical surfaces of the lower support plate and the upper support plate; and the middle support plate is arranged in a space surrounded by the slipping concave spherical surfaces and the embedded circular rings of the lower support plate and the upper support plate, and the diameter of the surrounded space is greater than that of the middle support plate. According to the multifunctional dual-curved-surface spherical shock-absorbing and shock isolation support disclosed by the invention, the limiting plates are arranged on the four sides of the upper part of the lower support plate, the embedded circular rings are arranged on the lower support plate and the upper support plate, the middle support plate is arranged in the space surrounded by the slipping concave spherical surfaces and the embedded circular rings of the lower support plate and the upper support plate, and the diameter of the surrounded space is greater than that of the middle support plate, so that the problem that a beam body falls can be effectively solved.

Description

technical field [0001] The invention relates to the technical field of bridge structures or buildings, in particular to a multifunctional hyperboloid spherical shock-absorbing and isolating bearing. Background technique [0002] Nowadays, steel structure bridges are widely used in highway bridges, and seamless lines are mostly used in railway bridges. The current hyperboloid spherical shock-absorbing and isolation bearings are often accompanied by vertical elevation during the horizontal sliding process, forming a phenomenon of beam body elevation, which leads to the redistribution of internal forces of the steel bridge and the flatness of the railway track, which is likely to cause traffic safety problems. Hidden danger. At the same time, the post-seismic displacement of the shock-absorbing and isolating support is usually designed according to the seismic calculation results, but there are various unpredictable factors during the earthquake, and the possibility that the p...
