Prefabricated pier and bent cap connecting system of fabricated beam bridge and construction method thereof

Abstract

The application provides a prefabricated pier and bent cap connecting system of a fabricated beam bridge and a construction method of the prefabricated pier and bent cap connecting system, and belongsto the technical field of building parts of roads, railways or bridges. The system comprises a prefabricated bridge pier, a bent cap, a steel member, a positioning plate, a fastener, and an epoxy resin layer; the prefabricated bridge pier, the steel member, the epoxy resin layer, the positioning plate and the bent cap are sequentially arranged from bottom to top, and the fastener penetrates through the positioning plate, the epoxy resin layer and the steel member and is fixed between the bent cap and the prefabricated bridge pier. The system is applied to beam bridge construction and has theadvantages of being simple in structure, convenient to assemble, high in implementation speed and the like.

Description

technical field [0001] The application relates to a prefabricated bridge pier and cover beam connection system and a construction method thereof of an assembled girder bridge, belonging to the technical field of construction parts of roads, railways or bridges. Background technique [0002] With the further advancement of bridge industrialization, the traditional construction method of all on-site pouring has gradually changed to a construction method in which part or most of the components are prefabricated in a factory and then transported to the site for installation. Compared with traditional construction methods, industrial production methods are the first What is solved is the connection between the various prefabricated components. In the process of bridge industrialization, the upper structure is earlier than the lower structure. The bridge industrialization mentioned at present mainly refers to the industrialization of the lower structure, that is, the cover beam, b...

AI Technical Summary

Problems solved by technology

[0004] First, the traditional sleeve connection method often requires pre-embedded steel connection sleeves in the prefabricated section of the cap girder or pier. In order to ensure reliable connection performance between the cap girder and the prefabricated pier, a large number of steel bars need to be pre-embedded in the prefabricated cap girder or pier Connecting sleeves, which greatly increase the cost of manufacturing piers and cap beams

[0005] Second, the prefabricated assembly method of the pre-embedded steel connection sleeve has high requirements for construction accuracy and grouting quality. During the assembly construction process, accurate positioning and grouting requirements between the components are required. At the same time, the grouting density in the sleeve is difficult. detection, which makes the sleeve connection method subject to certain restrictions in practical engineering applications
