A high-damping shock-absorbing and isolating seat used in bridge engineering

Abstract

The invention relates to the field of road and bridge equipment, in particular to a high-damping seismic isolation and reduction seat for bridge engineering. The high-damping seismic isolation and reduction seat comprises three bases, the three bases are distributed around a vertical axis by the equal angle, every two adjacent bases are fixedly connected through a connecting part, and each base comprises an upper supporting part, a lower supporting part, an outer wrapping part and a bottom plate. Each outer wrapping part is fixedly mounted on the upper end surface of the corresponding bottom plate and wraps the corresponding lower supporting part, and each upper supporting part is arranged on the corresponding outer wrapping part in a buckled mode. According to the high-damping seismic isolation and reduction seat for bridge engineering, the three bases are fixedly connected through connecting parts, combined use of the three bases increases the whole flexibility of a bridge, cooperation of the lower supporting parts and the outer wrapping parts in the inner portions of the bases and arrangement of damping spring can achieve the effect of seismic reducing and energy dissipation, the configuration shapes of the three bases are same, after being damaged, the bases can be replaced conveniently, and the interchangeability between the bases is improved.

Description

technical field [0001] The invention relates to the field of road and bridge equipment, in particular to a high-damping shock-absorbing and isolating seat used in bridge engineering. Background technique [0002] With the rapid development of national transportation facilities, the construction of roads and bridges is also becoming more and more perfect. Our country has a vast territory, and the geographical conditions in many regions are different. The requirements for roads and bridges that need to be built are also different. For important transportation tasks, if a bridge collapses in a strong natural disaster, it will cause untimely disaster relief, resulting in casualties of manpower and material resources, which will increase the difficulty of disaster relief. However, the construction of a stable bridge base is an important It is the most important, but the shock-absorbing base in the prior art all exists in one body, not only the structure is loaded down with trivia...

However, the construction of a stable bridge base is an important It is the most important, but in the prior art the shock-absorbing base exists in one piece, not only the structure is cumbersome, but also the maintenance after damage is quite troublesome, which increases a lot of unnecessary manpower output
