Prefabricated elastic concrete anti-seismic check block

Abstract

The invention discloses a prefabricated elastic concrete anti-seismic check block. The prefabricated elastic concrete anti-seismic check block comprises a cross beam and elastic check blocks, whereinthe upper surfaces of the two ends of the cross beam are oppositely provided with preformed grooves, and the inner walls of the bottoms of the preformed grooves are provided with cross grooves; the elastic check blocks are inserted in the preformed grooves, and a high-strength non-shrinkage cement grouting material is poured into gaps between the elastic check blocks and the preformed grooves, wherein each elastic block comprises a longitudinal end arranged in the corresponding preformed groove and a transverse end perpendicular to the corresponding longitudinal end, the middle of the bottom of each longitudinal end is crosswise provided with a first clamping block and a second clamping block, each first clamping block and the corresponding second clamping block are vertically arranged, each first clamping block and the corresponding second clamping block are clamped in the corresponding cross groove, the front end of each transverse end is provided with a mounting groove, and each mounting groove is internally provided with a buffer mechanism. The prefabricated elastic concrete anti-seismic check block has the advantages of being simple in structure, practical, convenient and simple and rapid in construction, and being capable of being replaced immediately after damage.

Description

Technical field: [0001] The invention relates to the field of anti-seismic bridges, in particular to an assembled elastic concrete anti-seismic block. Background technique: [0002] The powerful energy released instantly by the earthquake will cause huge damage to the buildings and infrastructure under the action of the earthquake. The damage of the bridge means the interruption of the lifeline, which directly hinders the disaster relief operations, increases the loss of life, property and indirect economic losses, and brings great harm to the aftermath of the disaster. Difficulties in recovery and reconstruction. Therefore, it is extremely important to improve the seismic performance of bridges. [0003] Judging from several major earthquake damages in recent years, many bridges were damaged as a whole due to lack of reasonable and effective anti-seismic measures or structures. Under the action of strong earthquakes, the lateral displacement of the beam body is relatively...

AI Technical Summary

Problems solved by technology

[0003] Judging from several major earthquakes in recent years, many bridges have not been equipped with reasonable and effective anti-seismic measures or structures, resulting in overall bridge damage.

Under the action of strong earthquakes, the lateral displacement of the beam body is relatively large, and it is easy to collide with the block, resulting in shear brittle failure of the block and even lateral drop of the beam, which eventually leads to the overall destruction of the bridge and huge loss of life and property. It is because the displacement of the beam body has not been effectively restrained under the action of strong earthquakes, and the energy of earthquake damage has not been reduced or dissipated.
