A hoisting method for the hoisting of separated bridge deck t-beams

Abstract

The invention discloses a traverse truss and a hoisting method for hoisting a separate bridge deck T beam. The traverse truss includes a first traverse device and a second traverse device, and the first traverse device includes two parallel The set "I" type first bottom beam, a plurality of first load-bearing beams are fixed between the first bottom beams; a first bridge erecting machine track is arranged on the first load-bearing beam; One end of the track of a bridge crane is also provided with an end stopper; the second traverse device includes two "I"-shaped second bottom beams arranged in parallel, and a plurality of second bottom beams are fixed between the second bottom beams. The second load-bearing beam; the upper surface of the second bottom beam is provided with a second bridge erecting machine track; an end stopper is also provided at one end of the second bridge erecting machine track; Move and other steps to complete the rapid hoisting of the separated bridge deck T beam in the case of a single bridge machine, and realize the fast and convenient lateral movement and amplitude of the bridge machine.

Description

technical field [0001] The invention relates to the field of bridge engineering construction devices, in particular to a hoisting method for hoisting a separated bridge deck T-beam. Background technique [0002] In the process of expressway construction, due to terrain constraints, separate bridge decks are often designed to separate the highway into upper and lower lanes, and there is a distance between the two bridge decks. This brings a lot of inconvenience to the hoisting of the T-beam. [0003] At present, domestic and foreign projects of this kind usually adopt two methods: [0004] The case of only one bridge erecting machine: A. Firstly carry out the hoisting construction of a single T-beam, and then withdraw the bridge erecting machine after the construction is completed, and carry out the construction of the second bridge erecting T-beam. This kind method is owing to will wait for the bridge deck concrete construction of having erected T girder, etc. strong, and ...

AI Technical Summary

Problems solved by technology

This method will waste a lot of manpower in disassembling the front legs of the bridge erecting machine, and waste a lot of time for the empty load transfer of the bridge erecting machine to the other side.

[0005] The situation of owning two bridge erecting machines: T-beam hoisting and panel construction of the bridge deck on both sides are carried out at the same time. This method is fast and saves time, but buying two bridge erecting machines will waste a lot of money, and the construction cost will be greatly increased, which cannot be achieved. expected economic goals
