To achieve the above object, the technical scheme is that：
A kind of overall fan-shaped across the width method for traversing of mobile formwork girder, it is characterised in that：
The method implement condition be:
A, cast-in-situ box girder use Construction Through Form on Traveler, and double width only puts into a set of mould bases；
B, the traversing construction place with larger area, and place foundation bearing capacity is preferable；
C, hydraulic flat car 1;
The construction process of the method：
A, original assembled place is carried out smooth and is widened, digging machine crawler belt is rolled repeatedly on traversing place, to ensure place
Bearing capacity；
B, every Pin girders position set temporary rest pier at 4, below casting concrete Extended chemotherapy；
C, right width mould bases are dropped down onto on temporary rest pier when being transferred from bridge to ground；
D, jack is being set near rearmost end temporary rest pier foremost, need to stagger hydraulic flat car entrucking position, will
Hydraulic flat car moves to girder and treats holding position；
E, hydraulic flat car rotating disk are highly adjusted, and mould bases girder jacking is left into temporary rest pier, and hydraulic pressure wooden handcart headstock can voluntarily
Position, the tailstock is in place by loading machine；Headstock is located in girder termination, and the tailstock is located in away from girder other end neighbouring position；
F, jack oil return make girder drop down onto on hydraulic flat car rotating disk, remove temporary rest pier, in hydraulic flat car rotating disk
Upper recruitment steel welded limiting prevents transverse shifting, and girder is fixed on into hydraulic flat car to drawing with chain block prevents from toppling；
Mould bases girder is gone to left width by G, hydraulic flat car with fan-shaped circuit by right width, and interim branch is set in Extended chemotherapy position
Pier, flat car rotating disk is left by jack by girder jacking, and flat car is opened from mould bases girder lower section；
H, jack oil return, mould bases girder are dropped down onto on left width temporary rest pier, and mould bases list Pin girders complete fan-shaped across traversing；
I, repeat the above steps D-H, completes across the width traversing construction of another Pin girders；
Overall fan-shaped across the width traversing construction of J, mould bases girder is completed.
The invention has the advantages that：
Inventive process avoids girder it is secondary tear open spelling and secondary precompressed, substantial saving in tear open spell mould bases girder needed for it is artificial
And machinery, and prepare prepressing materials without a large amount of again, efficiency of construction is substantially increased, with good economic benefit.

Specific embodiment
The invention discloses a kind of overall fan-shaped across the width method for traversing of mobile formwork girder.Enter below in conjunction with an embodiment
One step introduces the inventive method.
It is applicable the precondition of the inventive method：
（1）Cast-in-situ box girder uses Construction Through Form on Traveler, and double width only puts into a set of mould bases.
（2）Traversing construction place with larger area, and place foundation bearing capacity is preferable.
（3）Rated load is the hydraulic flat car 1 of 200t.
The construction process of the inventive method is：
1st, original assembled place is carried out smooth and is widened, digging machine crawler belt is rolled repeatedly on traversing place, to ensure place
Bearing capacity.
2nd, per Pin girders 1（Bottom has cushion block 14）Position sets temporary rest pier at 4, as shown in Figure 1：Temporary rest pier is by straight
Footpath 800mm steel pipe 11 and 2I45 shaped steel 12（There can be stiffener 15）Composition, casting concrete Extended chemotherapy 13, expands below
Basic 13 sizes are 2.5 × 1.2 × 0.8m.Consider that hydraulic flat car needs ground on the scene to travel back and forth, basic top surface is neat with ground
It is flat.
3rd, dropped down onto on temporary rest pier when right width mould bases is transferred to ground from bridge, temporary rest pier is apart from ground level
1.3m。
4th, jack 2 is being set near rearmost end temporary rest pier foremost（Stagger hydraulic flat car entrucking position
Put）, hydraulic flat car is moved into girder and treats holding position.
5th, the rotating disk 31 of hydraulic flat car 3,32 height can be adjusted between 1m-1.4m, mould bases girder jacking is left and is faced
When buttress about 5cm, hydraulic pressure wooden handcart headstock can be voluntarily in place, and the tailstock is in place by loading machine.Headstock is located in girder termination, the tailstock
It is located in away from girder other end 15m positions.
6th, such as Fig. 2, the oil return of jack 2 makes girder 1 drop down onto on the rotating disk 32 of hydraulic flat car 3, removes temporary rest pier,
Recruitment steel welded limiting prevents transverse shifting on hydraulic flat car rotating disk, and girder is fixed on into hydraulic pressure to drawing with 5T chain blocks
Flat car prevents from toppling.
Mould bases girder is gone to left width by the 7th, such as Fig. 3,4, hydraulic flat car with fan-shaped circuit by right width, in Extended chemotherapy position
Temporary rest pier is set, girder jacking is left by flat car rotating disk by jack, flat car is opened from mould bases girder lower section.
8th, jack oil return, mould bases girder is dropped down onto on left width temporary rest pier, and mould bases list Pin girders complete sector across width
It is traversing, such as Fig. 5.
9th, repeat above-mentioned step and play 4-8, complete across the width traversing construction of another Pin girders.
10th, overall fan-shaped across the width traversing construction of mould bases girder is completed.
It is only in sum presently preferred embodiments of the present invention, not for limiting practical range of the invention.It is i.e. all
The equivalence changes made according to the content of scope of the present invention patent and modification, all should be technology category of the invention.
