Novel corrugated steel web external prestress box girder bridge steering device

Abstract

The invention discloses a novel corrugated steel web external prestress box girder bridge steering device which comprises a cushion frame structure and a buckle frame structure vertically arranged atthe top of the cushion frame structure, the cushion frame structure and the buckle frame structure are the same in shape, and the cushion frame structure comprises a plurality of cushion plates with the same ruler diameter. A steering engine is arranged in the center of the base plate, the top output end of the steering engine is connected with the bottom end of a buckle frame structure, a load-bearing frame is arranged at the top of the buckle frame structure, the load-bearing frame is a square body, an opening is formed in the top of the load-bearing frame, and a plurality of limiting structures are further arranged on the outer side of the steering engine. And a column pipe corresponding to the limiting structure is arranged at the bottom of the base plate. The shapes of the cushion frame structure and the buckling frame structure correspond to each other, and the corresponding limiting structures and the corresponding column tubes are added to the cushion frame structure and the buckling frame structure, so that the cushion frame structure and the buckling frame structure can be adjusted to stretch out and draw back and buckled with the column tubes through the limiting structures, the supporting balance is enhanced, and the limiting protection effect is achieved.

Description

technical field [0001] The invention relates to the technical field of construction equipment, in particular to a novel corrugated steel web externally prestressed box girder bridge steering device. Background technique [0002] The box girder of reinforced concrete structure is divided into prefabricated box girder and cast-in-place box girder. The prefabricated box girder combined with the bridge erecting machine can be erected after the completion of the substructure, which can speed up the progress of the project and save the construction period; the cast-in-place box girder is mostly used for large continuous bridges. Commonly divided by materials, there are two main types, one is prestressed reinforced concrete box girder, and the other is steel box girder. Among them, the prestressed reinforced concrete box girder is constructed on site. In addition to the longitudinal prestress, some also have transverse prestress; the steel box girder is generally processed in the ...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies in the prior art, the present invention provides a new type of corrugated steel web externally prestressed box girder bridge steering device, which solves the problem that the existing girder bridge steering device has poor steering flexibility, and at the same time lacks restrictions after the steering, which is easy to There is a steering deviation, and it is not easy to accurately support and fix the position, and it is inconvenient to use
