Abstract

The invention discloses a steel plate superposed beam erecting system, which is applied to the construction process of crossing a swivel bridge section in a high-speed railway bridge, and comprises a carrying device for transporting a prefabricated steel plate superposed beam; the supporting device is arranged in the direction of the pier, located below the steel plate superposed beam and used for supporting and fixing the steel plate superposed beam; the hoisting device is used for hoisting the prefabricated steel plate superposed beam to a mounting position on the pier; and the bridging device is arranged on the roadbed and the piers and used for being matched with the hoisting device to hoist the steel plate superposed beam. According to the steel plate superposed beam erecting system, the carrying device of a unique structure is adopted, the transportation stability of the steel plate superposed beam is ensured, the supporting device and the steel plate superposed beam are matched, connected and fixed, supporting force is provided for the steel plate superposed beam in the vertical direction, and the problem that the steel plate superposed beam is suspended in the air is solved; meanwhile, the phenomenon that the steel plate superposed beam deviates and topples due to the mass center is avoided; the bridge erecting device can be better matched with a roadbed and a bridge pier to erect the steel plate superposed beam.

Description

technical field [0001] The invention belongs to the technical field of steel-concrete composite beams, and in particular relates to a steel plate composite beam erection system and an erection method. Background technique [0002] Steel-concrete composite bridges have many advantages such as light weight, large spanning capacity and fast construction progress. They have obvious economic benefits and competitiveness in transportation construction. At present, the country is vigorously promoting the construction of steel-concrete composite girder bridges. Since the construction sequence and construction method will affect the completed bridge state and stress characteristics of the steel-concrete composite girder bridge, it is necessary to select an appropriate construction method according to the actual situation. [0003] In the existing bridge erecting machine construction method, the large volume and large tonnage steel plate composite beam is difficult to transport in the...
