Abstract

The invention relates to an interchange steel bridge, and particularly to the interchange steel bridge and a manufacture method thereof. The interchange steel bridge belongs to the field of steel structures. The interchange steel bridge comprises a base plate unit, baffle plate units, longitudinal web units, a top plate unit and a cantilever unit. The longitudinal web plates are arranged above the base plate unit. Each longitudinal web plate is internally provided with a baffle plate unit. The top plate unit is arranged above the baffle plate units and the longitudinal web units. One side of the top plate unit is provided with the cantilever unit. The manufacture method comprises the following steps of laying a supporting moulding bed, testing the moulding bed, forming the interchange steel bridge, splicing the baffle plate unit at a middle position, performing one-time splicing on the longitudinal web plate at the middle position, splicing the baffle plate units at sides, performing secondary splicing on the longitudinal web units at the sides, splicing the top plate unit, splicing the cantilever unit, and performing quality detection on a steel bridge box girder. The interchange steel bridge and the manufacture method thereof have advantages of compact structure, high splicing precision, effective splicing strength improvement, and effective line type improvement of the manufactured bridge.

Description

technical field [0001] The invention relates to an interchange steel bridge, in particular to an interchange steel bridge and a preparation method thereof, belonging to the field of steel structures. Background technique [0002] The steel bridge units in the prior art cannot be mass-produced, and each produced road steel bridge unit has individual differences, which makes it impossible to make good splicing of multiple road steel bridge units, resulting in a decrease in performance and safety performance. Contents of the invention [0003] The invention mainly solves the deficiencies in the prior art, and provides an interchange steel bridge with a compact structure, which can be precisely formed by supporting tire frames and meets the requirements of mass production, and a preparation method thereof. [0004] Above-mentioned technical problem of the present invention is mainly solved by following technical scheme: [0005] An interchange steel bridge, comprising a botto...
