Fabricated bridge adopting reinforced concrete composite structure

Abstract

The invention provides a fabricated bridge adopting a reinforced concrete composite structure, and relates to the technical field of fabricated bridges, the fabricated bridge comprises a plurality of mounting bases, pier columns are mounted at the upper ends of the mounting bases, and a first cover beam and a second cover beam are mounted at the upper ends of the two pier columns correspondingly; the first cover beam and the second cover beam are spliced through a splicing assembly, a plurality of cover plates are installed on the upper surface of the first cover beam and the upper surface of the second cover beam, and guardrails are installed on the protection plates through installation assemblies. At the moment, the positioning plate and the mounting plate are matched with the upper bearing plate and the lower bearing plate, so that a sealing box is formed between the top ends of the first cover beam and the second cover beam, high-strength concrete is poured into the sealing box, and after the high-strength concrete is dried, the first cover beam and the second cover beam can be fixed together. And the stability is good.

Description

technical field [0001] The invention relates to the field of prefabricated bridges, in particular to a prefabricated bridge adopting a reinforced concrete composite structure. Background technique [0002] The prefabricated bridge is to divide the tall pier and abutment into several components vertically, according to a certain modulus and horizontally, pour it on the prefabricated site around the bridge site, transport it to the site by vehicle and ship, lift and assemble, and then splicing the bridge deck on the pier. On the stage, to achieve the purpose of rapid construction. Therefore, the fully prefabricated bridge structure is an effective means to speed up construction, reduce on-site pollution, and achieve low-carbon construction. Under the guidance of national policies and technological development, bridge prefabricated structures have also been widely used in various projects. Beam side panel, upper and lower chords of main box girder, diaphragm beam plate betwee...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides that when splicing the assembled bridge main body, the process is cumbersome, and after the splicing is completed, gaps are likely to appear between the parts, resulting in low stability and easy leakage. The situation will lead to safety hazards during the use of the bridge
