Abstract

The invention relates to a hyperboloid spherical vibration reduction and isolation support with a function of preventing beam lifting and beam falling. The support comprises a lower support plate, a middle support plate and an upper support plate. Limiting plates are arranged on four upper sides of the lower support plate respectively, and embedded rings are arranged outside slide concave spherical surfaces of the lower support plate and the upper support plate. The middle support plate is arranged in a space formed by the slide concave spherical surfaces of the lower support plate and the upper support plate and the embedded rings, and the diameter of the space is larger than that of the middle support plate. Therefore, the problem of beam falling can be solved effectively.

Description

technical field [0001] The invention relates to the technical field of bridge structures or buildings, in particular to a hyperboloid spherical shock-absorbing and isolating support with the functions of anti-lifting beams and anti-falling beams. 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 durin...
