The girder form that current municipal viaduct adopts mainly contains: the large case beam of integral cast-in-situ, prefabricated small box girder or T beam, steel box-girder etc., main girder construction adopts that full framing integral cast-in-situ, Bridge Erector full span erection are assembled substantially, crawler crane or the lifting of mobile crane piecemeal connect, although there is its reasonability, also there is following shortcoming:
(1) raft support method construction takies both wired path area, existing road traffic is easily caused to interrupt or road width reduction, the traffic capacity declines, easily cause traffic congestion, and on-site construction processes is many, noise is large, and speed of application is slow, cycle is long, causes very large impact to the work of surrounding resident and life;
(2) Bridge Erector method erecting small box girder, can only unidirectionally hole-specifically advance, construction speed is slow, transition cost is high, and bridge formation bridge need be dismantled and again assembled, and prefabricated small box girder is installed in the lifting of crawler crane method, small box girder weight often reaches 70 ~ 150t, the transport of case beam is limited by factors restriction, easily causes traffic congestion, and may cause the damage to existing road and bridge;
(3) mobile crane or the segmented installation steel box-girder of crawler crane piecemeal, also need to arrange falsework being welded to connect for girder steel, a large amount of Site Welding is unfavorable for ensureing girder steel quality, and a large amount of welding spark causes very large potential safety hazard to traffick and pedestrian, and structure economics is not good.
Therefore, finding the rapid enforcement technology of a kind of municipal bridge, reduce the harmful effect because bridge construction brings to urban traffic and resident living as far as possible, have good economy simultaneously, is very necessary.
Summary of the invention
The object of the invention is for above-mentioned present situation, aim to provide a kind of lightweight, speed is fast, the cycle is short, it is little to disturb, take up an area less, noise is low, does not affect the enforcement technology of the many girders formula shaped steel-double layer concrete bridge deck compound beam of the original traffic in city.
The implementation of the object of the invention is, the enforcement technology of many girders formula shaped steel-double layer concrete bridge deck compound beam, and concrete steps are as follows:
1) in " work " font shaped steel top flange plate end face welding WELDING STUDS, WELDING STUDS group is formed; Produce bottom plate steel mesh reinforcement in factory modularization, utilize bottom layer of the reinforcing steel net to be prefabricated in the factory and generate bottom precast concrete bridge deck;
2) paste elastic rubber strip one at " work " font shaped steel top flange plate edge, between elastic rubber strip one, pour into epoxy mortar leveling layer;
3) lifting also installing bottom layer precast concrete bridge deck, build slightly expanded concrete and longitudinal wet joint concrete in the WELDING STUDS groove between bottom concrete bridge deck;
4) utilize mobile crane to lift by crane and the compound beam that multi-disc formed by " work " font shaped steel and bottom concrete bridge deck is installed, utilizing the longitudinal plate seam between elastic rubber strip two seal combination beam;
5) produce top layer bridge deck steel mesh reinforcement in factory modularization, transport and top layer concrete slab steel mesh reinforcement is installed, top plate steel mesh reinforcement and anchor bar colligation are linked together;
6) cast-in-place top layer bridge deck concrete on bottom concrete bridge deck, form top layer concrete slab, upper strata concrete slab is connected by anchor bar and WELDING STUDS with bottom concrete plate, and namely upper strata concrete slab and bottom concrete plate connect into many girders formula shaped steel-double layer concrete bridge deck compound beam by anchor bar and WELDING STUDS.
Adopt the present invention first in every sheet " work " font shaped steel top flange welding WELDING STUDS, then combine with bottom concrete plate; Utilize the mobile crane horizontal installation in whole hole piecewise to organize compound beam more, plate seam between recycling elastic rubber strip seal combination beam, bottom concrete plate as template, finally cast-in-place upper strata concrete slab on bottom concrete plate, upper strata concrete slab is connected by anchor bar and WELDING STUDS with bottom concrete plate, forms multiple layer combination girder construction.
The present invention, from design, manufacture, construction, economic dispatch factor, has the features such as lightweight, speed is fast, the cycle is short, take up an area less, noise is low, does not substantially affect the original traffic in city, have a extensive future at municipal bridge.
