Problems solved by technology

However, the traditional reinforced concrete block is often damaged during the earthquake, resulting in shearing or breaking, and its anti-seismic form is the direct collision between the beam and the block, which has no energy dissipation capacity and is difficult to repair

Abstract

The invention discloses an anti-beam-falling prevention device based on a paper folding springback mechanism. The anti-beam-falling prevention device comprises a steel check block upper bottom plate,a steel check block upper part, a steel check block lower part, a steel check block lower bottom plate and a paper folding springback mechanism arranged between the steel check block upper part and the steel check block lower part, wherein the steel stop block upper bottom plate is fixed with the lower bottom surface of a bridge, the steel stop block upper part is fixed with the steel stop block upper bottom plate, the steel stop block lower part is fixed with the steel stop block lower bottom plate, and the steel stop block lower bottom plate is fixed with the top surface of a steel corbel; the paper folding springback mechanism comprises a sleeve, a paper folding type structure and a composite material plate, the sleeve is fixed to the inner side of the steel check block upper part, andwhen the paper folding springback mechanism is extruded by the lower portion of the steel check block in the bridge following direction, compression deformation can be generated in the direction, andmeanwhile springback force is generated. Earthquake energy is absorbed through deformation of the paper folding springback mechanism so as to relieve the impact effect of the earthquake effect on thebeam and the check block, and the beam can be reset after the horizontal effect is finished.

Description

technical field [0001] The invention relates to the technical field of anti-fall beams for bridges, in particular to an anti-fall beam device based on an origami rebound mechanism. Background technique [0002] With the development of transportation infrastructure construction, viaduct bridges have played an important role in modern transportation networks. However, under the action of strong earthquakes, when the displacement of the upper and lower structures of the bridge is too large, collisions between beams or beams and platforms and damage to supports may occur. After the support is damaged, the beam body displacement in the direction of the bridge is easy to occur, causing beam falling earthquake damage, resulting in the paralysis of the traffic network and huge losses. Therefore, it is very necessary to take preventive measures against falling beam earthquake damage. [0003] At present, the stopper is a kind of seismic construction measure often used in bridge des...
