Bidirectional guide rail friction pendulum vibration isolation support with anti-pulling function

Abstract

The invention relates to a bidirectional guide rail friction pendulum vibration isolation support with an anti-pulling function. The bidirectional guide rail friction pendulum vibration isolation support comprises an upper support plate assembly connected with a building upper part structure and a lower support plate assembly connected with a building lower part structure. The upper support plateassembly and the lower support plate assembly are oppositely arranged. An upper guide rail block is fixedly arranged on the inner side of the upper support plate assembly. A lower guide rail block isfixedly arranged on the inner side of the lower support plate. A sliding block is arranged between the upper guide rail block and the lower guide rail block. An upper sliding groove matched with the upper part of the sliding block is formed in the upper guide rail block. A lower sliding groove matched with the lower part of the sliding block is arranged on the lower guide rail block. The upper sliding groove and the lower sliding groove are oppositely arranged in the vertical direction. The upper part of the sliding block is slidably connected with the upper sliding groove, and the lower partof the sliding block is slidably connected with the lower sliding groove. The bidirectional guide rail friction pendulum vibration isolation support with the anti-pulling function can limit the vertical displacement of the support, is reasonable in stress, simple in structure, safe, reliable and good in vibration isolation effect and can be widely applied to buildings and bridge engineering.

Description

Technical field [0001] The invention relates to the technical field of building shock absorption, in particular to a bidirectional guide rail friction pendulum type shock isolation support with an anti-pull function. Background technique [0002] Since the 1980s, friction pendulum vibration isolation bearings have been widely used in building structures and bridge engineering due to their small structural size and the ability to control the isolation period of the structure. [0003] The working principle of the friction pendulum damping and isolating bearing is relatively simple: the upper structure of the building is supported on a slidable curved surface, and when the upper structure and the lower structure of the building are relatively displaced, it moves like a pendulum. Therefore, any horizontal movement will produce a vertical lift of gravity. If friction is neglected, the motion equation of the system is similar to the motion of a pendulum of equal mass, and the pendulum l...
