It is new to carry out assembly, then utilize assembled mobile formwork to carry out another width construction of cast-in-situ box-beam.Such a method there are mobile formwork
Girder needs the shortcomings of secondary spelling is torn open, time-consuming for secondary precompressed, and how costly mechanical equipment input is.
The content of the invention
It is an object of the invention to provide a kind of overall fan-shaped across the width method for traversing of mobile formwork girder, mainly solve above-mentioned
Technical problem present in the prior art, it avoids the secondary spelling of mobile formwork girder from tearing open, secondary precompressed, reduces mechanical equipment and people
Member's input, saves construction cost, accelerates construction progress.
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：
This method implement condition be:
A, cast-in-situ box girder uses Construction Through Form on Traveler, and double width only puts into a set of mould bases；
B, there is the traversing construction place of larger area, and place foundation bearing capacity is preferable；
C, hydraulic flat car 1;
The construction process of this method：
A, original assembled place is carried out smooth and widened, digging machine crawler belt rolls repeatedly on traversing place, to ensure field
The bearing capacity on ground；
Temporary rest pier at 4 is set per Pin girders position, below casting concrete Extended chemotherapy B,；
C, dropped down onto when right width mould bases is transferred to ground from bridge on temporary rest pier；
D, jack is set near front end and rearmost end temporary rest pier, need to stagger hydraulic flat car entrucking position
Put, hydraulic flat car is moved to girder treats holding position；
E, hydraulic flat car turntable is highly adjusted, and the jacking of mould bases girder is left temporary rest pier, hydraulic pressure wooden handcart headstock can be certainly
Row is in place, and 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 makes girder drop down onto on hydraulic flat car turntable, removes temporary rest pier, in hydraulic flat car
Recruitment steel welded limiting prevents transverse shifting on turntable, and girder is fixed on hydraulic flat car to drawing with chain block prevents from inclining
Cover；
G, mould bases girder is gone to left width by hydraulic flat car with fan-shaped circuit by right width, is set in Extended chemotherapy position interim
Buttress, leaves flat car turntable, flat car is opened from below mould bases girder by jack by girder jacking；
H, jack oil return, mould bases girder are dropped down onto on left width temporary rest pier, and mould bases list Pin girders complete sector across width
It is traversing；
I, repeat the above steps D-H, completes across the width traversing construction of another Pin girders；
J, overall fan-shaped across the width traversing construction of mould bases girder is completed.
The invention has the advantages that：
Secondary inventive process avoids girder tears spelling and secondary precompressed open, substantial saving in tear open and spells needed for mould bases girder
It is manually and mechanical, and without largely preparing prepressing materials again, construction efficiency is substantially increased, it is with good economic efficiency.

Embodiment
The invention discloses a kind of overall fan-shaped across the width method for traversing of mobile formwork girder.Below in conjunction with an embodiment come into
One step introduces the method for the present invention.
It is applicable in the precondition of the method for the present invention：
（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 method for the present invention is：
1st, original assembled place is carried out smooth and widened, digging machine crawler belt rolls repeatedly on traversing place, to ensure field
The bearing capacity on ground.
2nd, per Pin girders 1（Lower part 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 pipes 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 and ground are neat
It is flat.
3rd, dropped down onto when right width mould bases is transferred to ground from bridge on temporary rest pier, temporary rest pier is apart from ground level
1.3m。
The 4th, jack 2 is set near front end and rearmost end temporary rest pier（Stagger hydraulic flat car entrucking position
Put）, hydraulic flat car is moved into girder and treats holding position.
5th, the turntable 31 of hydraulic flat car 3,32 height can be adjusted between 1m-1.4m, and the jacking of mould bases girder 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. 2,2 oil return of jack make girder 1 drop down onto on the turntable 32 of hydraulic flat car 3, remove temporary rest pier,
Recruitment steel welded limiting prevents transverse shifting on hydraulic flat car turntable, and girder is fixed on 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 turntable by jack, flat car is opened from below mould bases girder.
8th, jack oil return, mould bases girder are 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 presently preferred embodiments of the present invention in summary, is not used for limiting the practical range of the present invention.It is i.e. all
The equivalent changes and modifications made according to the content of scope of the present invention patent, all should be the technology category of the present invention.
