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

Abstract

The application provides a prefabricated pier connecting system of a fabricated beam bridge and a construction method thereof, and belongs to the technical field of building parts of roads, railways or bridges. The system comprises a plurality of prefabricated bridge piers and steel members arranged between the adjacent prefabricated bridge piers, the steel members are arranged in pairs, each steel member comprises a fastener, an end plate and a connecting plate, the connecting plate and the fastener are installed on one face of the end plate, and an epoxy resin layer is laid on the other faceof the end plate; the connecting plates and the fasteners are embedded into the prefabricated pier, and the epoxy resin layer is arranged between the pair of end plates. The system is applied to beambridge construction and has the advantages 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 connection system of an assembled girder bridge and a construction method thereof, belonging to the technical field of construction parts of roads, railways or bridges. Background technique [0002] With the further advancement of bridge industrialization, the construction method has gradually changed from the traditional on-site pouring of all components to factory prefabrication of some or most of the components, and then transported to the site for installation; compared with traditional construction methods, the industrial prefabrication method first requires 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 caps, piers and cover beams. The m...

Problems solved by technology

[0004] On the one hand, the sleeve connection method often requires pre-embedded steel connection sleeves in the prefabricated sections of the pier. The increase in the number of steel connection sleeves will greatly increase the cost of manufacturing pier columns

[0005] On the other hand, the prefabricated assembly method of the pre-embedded steel connection sleeve has high requirements on construction accuracy and grouting quality. During the assembly construction process, there are strict requirements on the accurate positioning and grouting of the various components, and the inside of the sleeve The density of grouting is difficult to detect, which makes the sleeve connection method subject to certain restrictions in practical engineering applications
