Composite shock insulation support

Abstract

The invention provides a composite shock insulation support, and relates to the technical field of shock insulation supports. The composite shock insulation support is designed to solve the problem that energy consumption mechanisms of traditional shock insulation supports are single. The composite shock insulation support comprises an upper connecting plate, a lower connecting plate, a shock absorption and insulation unit clamped between the upper connecting plate and the lower connecting plate and multiple elastic shock insulation seats arranged around the shock absorption and insulation unit. The elastic shock insulation seats are located between the upper connecting plate and the lower connecting plate, the upper ends of the elastic shock insulation seats are detachably and fixedly connected with the upper connecting plate, and the lower ends of the elastic shock insulation seats are detachably and fixedly connected with the lower connecting plate. The composite shock insulation support is a novel shock insulation support designed by combining the advantages of a rubber shock insulation support and a swing type shock insulation support, the constitutive curve of a traditional shock insulation support is changed, the performance of the shock insulation support is improved, the force transmission path can be continuous and ceaseless under the work condition that the shock insulation support is pulled, and therefore reliability of shock absorption and insulation of the shock absorption and insulation unit is guaranteed.

Description

technical field [0001] The invention relates to the technical field of shock-isolation bearings, in particular to a composite shock-isolation bearing. Background technique [0002] In the design of bridges and building structures, it is usually necessary to consider factors such as earthquakes, temperature, subsidence of foundation stones, and frequent hurricanes that may cause adverse effects on the building structure, and the shock-absorbing and isolation bearings can not only provide reliable vertical bearing for the upper structure , and can also provide a certain rotation and displacement for the upper structure, so as to achieve the purpose of shock absorption and shock isolation, so it has been widely used. [0003] Friction pendulum isolation bearings and rolling isolation bearings are a type of bearings designed based on the pendulum theory, and are often used for vertical support and horizontal shock absorption of structures such as bridges or buildings. The main ...
