Description
Technical field
A kind of Bridge Erector is the utility model is related to, on particularly a kind of asymmetric framing prefabricated case beam beam of achievable large-tonnage
The Bridge Erector of the whole two-way erection in hole.
Background technology
Using large-scale transportation rack device, realize and beam is transported on beam car beam, the construction method of Bridge Erector full span erection, there is quality
Reliably, efficiency high, the advantages that smaller, is influenceed on traffic and environment.In existing railway engineering, on large-tonnage prefabricated case beam beam
Fortune beam, the construction method of a piece of box beam of Bridge Erector full span erection are used widely.In highway engineering, only Hangzhou Gulf Great Bridge is carried out
Cross on large-tonnage prefabricated case beam beam and transport the construction of beam, by a variety of auxiliary equipment, its Bridge Erector can the left and right width two panels of full span erection
Box beam.
When Bridge Erector is reversely set a roof beam in place, transportation rack device u-turn need to be carried out, is generally lifted transportation rack device using lifting beam machine
Lower bridge, packed by beam car after Bridge Erector reversed end for end on ground, then lift bridge and carry out reversely fortune and set a roof beam in place operation.
Traditional large-tonnage box beam bridge formation machine set up different spans box beam become across when, typically need auxiliary leg, become across program compared with
It is less efficient to be cumbersome.
Traditional large-tonnage box beam bridge formation machine is complicated, and Bridge Erector need to typically carry out small disintegration, and needs to have under bridge
Enough places, operation of reversely setting a roof beam in place is carried out after could reversing end for end, it is impossible to realize and directly reversed end for end on simple efficient bridge.
Traditional large-tonnage box beam bridge formation machine is generally a piece of box beam of full span erection single width or whole by more auxiliary equipment
Aperture frame sets left and right double width two panels box beam, it is impossible to the left and right width two panels large-tonnage prefabricated case beam of direct full span erection.
Traditional large-tonnage box beam bridge formation machine Bridge Erector typically realizes the erection in first and last hole, it is necessary to carry out by front leg strut turnover
Certain dismounting, operation procedure is relatively complicated, increases labor intensity.
In urban elevated bridge engineering, to make full use of space under bridge, reduce bridge pier as far as possible and take up an area width, gradually adopt
The unsymmetric structure design that top prefabricated case beam structure both sides cantilevers does not wait.It is asymmetric prefabricated that traditional Bridge Erector sets up large-tonnage
Box beam, box beam occur it is unstable and by turn round phenomenon, less can ensure that Bridge Erector security and stability.
