Shock absorber for building bridge construction transformation

Abstract

The invention discloses a shock absorber for building bridge construction transformation, which comprises bridge edges and positioning steel mounted at the edge positions in an embedded manner, positioning bottom plates are mounted between the bottom edges of the adjacent bridge edges in a bolt positioning manner, and limiting holes are formed in the positioning bottom plates; the bottom plate positioning piece is rotationally installed on a bolt fixing plate on the edge of the bridge edge, a reset spring is fixed to the rotating connection position of the bottom plate positioning piece, and a connecting piece is installed in the positioning steel above the bottom plate positioning piece in a penetrating mode; the liquid sealing plug is fixed to the tail end, located in the positioning steel, of the connecting piece; the positioning column is fixed in the middle of the hollow-out structure at the end part of the connecting piece; and the upper end of the pressed rod is hinged to the bottom of the connecting piece. According to the shock absorber for building bridge construction transformation, potential energy conversion of impact loads can be efficiently achieved, the shock absorption effect is improved, the shock absorption effect influence caused by the environment temperature is reduced, and the service life of the shock absorber is efficiently prolonged.

Description

technical field [0001] The invention relates to the technical field related to bridge reconstruction, in particular to a shock absorber for construction and reconstruction of building bridges. Background technique [0002] The construction and construction of the bridge will be rebuilt according to the requirements of the use and residence. In order to meet the needs of daily life, the old bridge needs to be artificially rebuilt to widen its use width to meet the traffic and transportation of the bridge. In the widening of the old bridge During reconstruction, in order to reduce the bridge dislocation and damage caused by the deflection difference between the old and new bridges, it is necessary to install auxiliary positioning and shock absorbing devices at the junction of the old and new bridges to maintain the normal traffic of the bridge and effectively extend its service life. [0003] Yet the existing bridge construction reconstruction uses the damping device to have t...

Problems solved by technology

[0007] The object of the present invention is to provide a kind of shock absorber for construction and reconstruction of building bridges, to solve the above-mentioned background technology. The vibration caused by the reaction force is difficult to effectively support and weaken, so that the protection effect of the bridge connection position is not strong. Only the spring structure is used for buffering and shock absorption. Due to the weakening of elasticity by temperature, its buffering and shock absorption capacity cannot fully meet the requirements of the bridge. Issues required for shock absorption during traffic
