Mobile formwork bridge fabrication machine is a kind of template that carries, and utilizes two groups of steel case beam support templates, concrete beam is pursued the construction machinery of hole cast in situs.Construction Through Form on Traveler characteristics: be applicable to build bridge superstructure in deep water or high pier stud use support or the uneconomic situation of other job practices, the number of turnover is many, turnaround time is short, the use auxiliary equipment is few, reduce the waste of manpower goods and materials, be specially adapted to the multispan in-situ beam casting, both guaranteed workmanship, again can accelerating construction progress, have good economic benefit.
In Chong Qi passage (Shanghai section) V mark 7 * 50m continuous box girder mobile formwork bridge fabrication machine construction technology, the design of exterior sheathing and construction are larger construction Difficulties, if often all complete by mounting or dismounting across the case girder steel formwork, its construction cost is larger, and box girder construction complete after exterior sheathing dismounting and move to next and affect greatly the duration across construction.Therefore, need a kind of moving die plate of design system to solve above problem.
Summary of the invention
The present invention is that will to solve existing mobile formwork bridge fabrication machine exterior sheathing construction cost high, the technical problem of circulation difficulty, and provide one from folding moving die plate system, this system utilizes the girder of mobile formwork and supports chassis, exterior sheathing is divided into two groups of left and right traversing to both sides, mobile formwork is moved on to next cross-location, with abundant minimizing exterior sheathing input amount, reduce construction cost, save the duration.
To achieve these goals, the technical scheme that the present invention takes: a kind of from folding moving die plate system, comprise the mobile formwork girder, horizontal-associate system, bed die, side form, side form supports, and supports chassis, and be characterized in: bed die is made of left and right template, the horizontal-associate system is made of left and right framework, and left and right template is fixedly connected with the left and right beam sides of mobile formwork girder by left and right framework respectively; Two side templates are shelved on respectively above the left and right beam of mobile formwork girder, the left and right beam of mobile formwork girder fall within respectively support chassis in, on the balladeur train of the outside.
Support chassis by bogie frame, inboard balladeur train, outside balladeur train, the support top oil cylinder forms, in bogie frame two ends connect respectively, outside balladeur train, the middle support top oil cylinder that connects.
The left and right framework of horizontal-associate system is by horizontal-associate, spiral top, and connecting bolt forms, and during matched moulds, the horizontal-associate of left and right framework is fixed by connecting bolt; Spiral top contacts with at the bottom of bed die, is used for adjusting the bed die absolute altitude.
Beneficial effect of the present invention is:
1) transfer and installation rate are fast., need not hanging device and shift by horizontal-associate system and the traction of support chassis from the folding template system.
2) use safety.The bolt that the side form of template system supports by side form connect with girder on, bed die connect with horizontal-associate on, safe and reliable.
3) technique is advanced.This technique changes the mobile formwork exterior sheathing from the folding template into by routine dismounting template, has reduced the input amount of template, has also saved the duration.

The specific embodiment
The present invention is further illustrated below in conjunction with accompanying drawing and embodiment.
As Fig. 1, of the present invention from folding moving die plate system shown in 2, comprise mobile formwork girder 1 horizontal-associate system 2, bed die 6, side form 7, side form supports 8, supports chassis 4 etc.
Bed die 6 is made of left and right template, and horizontal-associate system 2 is made of left and right framework, and left and right template is fixedly connected with the left and right beam sides of mobile formwork girder 1 by left and right framework respectively; Two side templates 7 are shelved on respectively above the left and right beam of mobile formwork girder 1, the left and right beam of mobile formwork girder 1 fall within respectively support chassis 4 in, on outside balladeur train 13,14.
As shown in Figure 3, horizontal-associate system 2 is by horizontal-associate 10, spiral top 11, and connecting bolt 16 forms, and connecting bolt 16 forms, and during matched moulds, the horizontal-associate 10 of left and right framework is fixing by connecting bolt 16, and spiral top contact with 6 ends of bed die, for adjustment bed die 6 absolute altitudes.
As shown in Figure 4, support chassis 4 by bogie frame 12, inboard balladeur train 13, outside balladeur train 14, support top oil cylinder 15 forms.In bogie frame 12 two ends connect respectively, outside balladeur train 13,14, the middle support top oil cylinder 15 that connects.
Specific construction process of the present invention:
1) bed die 6 upper ends are beam structure, and side template 7 is shelved on mobile formwork girder 1.
2) by mobile formwork 1 integral body being transferred 200mm, the whole demoulding of mobile formwork 1.
3) support on chassis 4 before and after mobile formwork 1 integral body falls within, unclamp horizontal-associate system 2, start the sideslip oil cylinder that supports on chassis 4, it is traversing to both sides that mobile formwork 1 is divided into left and right beam, handle simultaneously the sideslip oil cylinder of single girder front and back supporting chassis 4, the left and right beam of mobile formwork 1 is outside traversing 3.75m respectively, and mobile mobile formwork 1 is moved on to next cross-location.
4) after vertical shift puts in place, the left and right beam of mobile formwork 1 is closed up to the middle part put in place, connect horizontal-associate 2 and bed die 6 middle part connecting bolts.
