Technical field
The utility model relates to a kind of double width separate type bridge superstructure construction equipment, particularly relates to the mobile formwork girder whole lateral moving construction being applicable to elevating capacity or steric requirements existence limitation.
Background technology
Tradition mobile formwork is traversing:
Mobile formwork is traditional bridge superstructure construction equipment, and when bridge span number is few, after single width has been constructed, often need the traversing width that turns to carry out another width construction, Normal practice is:
1., after mobile formwork girder entirety being hung bracket with large-scale lifting appliance, bracket is lifted successively to installation site in place, then by place in main cable and girder to the bracket of installation;
2. installation site entirety is transported to after mobile formwork structure being disintegrated again assembled.
The limitation of traditional construction:
Along with the development of construction technology, bridge design strengthens gradually across footpath, and also strain is large mutually, change is heavy for corresponding mobile formwork, and integral hoisting is traversing needs the crane gear that elevating capacity is very large to carry out operation, and organize difficulty large, site requirements is high, and Expenses Cost is large.And if will mobile formwork disintegrate after reinstall, then after installation is complete, need again to carry out load precompressed and evidence obtaining work, expend long in time limit, and uneconomical.
Utility model content
The purpose of this utility model is: the mobile formwork girder whole lateral moving guiding device proposing a kind of novelty, the dependence to large lifting equipment and place can be reduced, the whole lateral moving of girder can be completed again in small space below bridge rapidly, save material simultaneously, simplify construction, safe and reliable, reduction of erection time, economy and facility.

The main scheme of aforementioned the utility model and each further selection scheme thereof can independent assortment to form multiple scheme; be the utility model can adopt and claimed scheme: as the utility model; each selection can select any combination with other; those skilled in the art can understand there is multiple combination according to prior art and common practise after understanding the present invention program; be the claimed technical scheme of the utility model, do not do exhaustive at this.
Workflow of the present utility model:
The girder length of mobile formwork is generally longer than span of bridge about 1/4, carries out whole lateral moving, must cross the substructure (bridge pier) of having constructed of bridge, just can be displaced to another width of bridge.By arranging at least two parallel cross moving tracks below girder, transfer mobile formwork girder on track, utilize the utility model, hold girder between bridge substructure, do longitudinal direction and transverse movement, entirety detours and crosses pier shaft.
After the utility model holds mobile formwork girder by upper slide system, lengthwise movement (the vertical cross moving track lengthwise movement of mobile formwork girder) is completed by relative displacement between upper slide system with mobile formwork girder, then between lower skateboard system and cross moving track, relative displacement completes transverse movement (lower skateboard system is laterally slided along cross moving track), during transverse movement, sledge system motion on different track is asynchronous, make mobile formwork girder and bridge axis produce angle, thus detour and cross substructure.
The beneficial effects of the utility model: adopt this to overlap traversing guiding device, break through the restriction that construction plant is narrow and small, reduce large-scale lifting installation exercise to reduce security risk, strengthen the flexibility that mobile formwork turns width construction, it is simple to operate, material less investment, quick construction, safety economy.
1, practical:
Without the need to large lifting equipment, also can complete mobile formwork girder whole lateral moving rapidly, site condition dependence is little simultaneously, and the headroom that only bridge need be utilized limited, sets up easy traversing guiding device and just can complete whole lateral moving below bridge.
2, speed of application is fast:
Except the bridge of the nose and the structure needs that conflict with pier shaft are removed temporarily, all the other structures can be traversing in place in the lump with girder, saved the component dismounting particularly difficulty of the independent dismounting of bracket and time loss.It also avoid the loss of time that disintegration, precompressed and evidence obtaining bring, accelerate speed of application.
3, good economy performance:
Traversing guiding device makes simple, easy to operate, without the need to other supporting facility, can arrange, significantly utilize existing component in conjunction with the running gear of mobile formwork self, reduces material and drops into.
4, safety and stability:
Consider mould bases girder to detour pier shaft at Near Ground, avoid the risk that upper air installing is crossed over, it also avoid the aerial assembled difficulty of large-scale bracket component.
5, the bridge of the nose can splice, without the need to independent holding time after removing temporarily after next completes across concreting again.
