Abstract

The invention relates to a rigid tension pendulum for a bridge. The objective of the invention is to effectively solve the problem of negative reaction of the bridge. The rigid tension pendulum is adaptive to the longitudinal displacement of a beam end and is not required to be replaced in the design life of the bridge. The rigid tension pendulum comprises an upper pull plate which is fixedly arranged on the longitudinal end portion of a beam body, an anchoring device which is fixedly arranged on a bridge pier, and a steel-eye rod which passes through a top cap and a pier column; the upper end and lower end of the steel-eye rod are respectively connected with the upper pull plate and a lower pull plate respectively through hinges; and the lower part of the steel eye rod is fixedly connected with the anchoring device.

Description

technical field [0001] The invention relates to bridges, in particular to a bridge rigid tension pendulum, which can effectively solve the problem of bridge negative reaction force, and basically does not restrict the longitudinal displacement of the bridge in normal use, and does not need to be replaced within the design life of the bridge. Background technique [0002] With the rapid development of bridge construction in our country, more and more long-span bridges have been built. Due to the limitation of bridge structure form and hole-span layout, the problem of negative reaction force of supports in bridge design has become increasingly prominent. [0003] At present, for small and medium-span bridges, the negative reaction force of the support is small, which can usually be solved by setting tension bearings. For example, spherical steel bearings, pot type and plate rubber bearings can be used as tension bearings, and plate rubber tension and compression supports The s...
