Standby technical field.
Background technology
In traditional Construction Through Form on Traveler, due to the limitation of hanging device, the scene in reinforcing bar to template that need to manually have bad luck is tied up
Prick, the assembling reinforcement cycle is 3-5 days, and this in-process can not carry out process, cause part worker to leave unused, influence bridge construction
Duration.Also, the assembling reinforcement in template, low construction efficiency, labor intensity are big.
The content of the invention
The present invention is intended to provide gantry crane system and its construction method that a kind of mobile formwork of arranging in pairs or groups uses, the straddle truck system
The supporting leg of system can both walk along girder, can also be walked along mobile formwork, convenient transfer steel reinforcement cage, can greatly shorten and apply
In the work cycle, improve efficiency of construction.
To achieve these goals, the technical solution adopted in the present invention is：
A kind of gantry crane system that mobile formwork uses of arranging in pairs or groups, including crane span structure, two supporting legs for being fixed on crane span structure both sides；Its structure
Feature is, in addition to is installed on the walking mechanism of supporting leg lower end, the first guide rail and the second guide rail；
The walking mechanism includes drive device, inner side running part and outside running part installed in supporting leg lower end；The inner side
Running part is arranged on the supporting leg lower end inside, and the outside running part is arranged on the supporting leg lower end outside, and inner side is walked
Portion is located at the inner side of outside running part；
The drive device is used to drive the inner side running part to walk along the first guide rail, and for driving the outer skidding
Portion is walked to walk along the second guide rail；First guide rail is used for the two side ends for being arranged on concrete girder, and second guide rail is used
In the two side ends for being arranged on mobile formwork exterior sheathing, and first guide rail is located at the inner side of the second guide rail.
Thus, the present invention sets inner side running part and outside running part, Ke Yishi creatively under single supporting leg simultaneously
Existing supporting leg（Portal frame）On girder walking and/or exterior sheathing it is up walk purpose so that convenient transfer steel reinforcement cage, contracting
Short construction period, improving efficiency of construction becomes possibility.
Inner side of the present invention is for girder center line, and the side close to girder center line is inner side, far
Side from girder center line is outside.
According to an embodiment of the invention, further optimization can also be made to the present invention, below the skill to be formed after optimization
Art scheme：
Preferably, the drive device includes the motor mounted in supporting leg bottom, and the output end of the motor is connected with reductor, and this subtracts
Fast machine is connected by transmission mechanism and the inner side running part on power transmission shaft and outside running part.Further, the transmission
Mechanism includes the first gear being connected with output end of reducer, the second gear on power transmission shaft；The first gear and the
Two meshed transmission gears.
In order to reduce the frictional resistance of walking, the inner side running part is the first disk roller, and first disk roller is walked first
On guide rail；The outside running part is the second disk roller, and second disk roller is walked on the second guide rail.Walked in order to facilitate disk roller,
The first guide rail as the first disk roller walking track is housed in the two side ends of the girder, is equipped with the two side ends of the exterior sheathing
The second guide rail as the second disk roller walking track.Gauge between first guide rail is less than the rail between second guide rail
Away from.
In order to adjust the position of the second guide rail, regulating block is housed between second guide rail and exterior sheathing.Further,
In order to avoid the second guide rail produces the bottom of interference effect, the outboard end of the regulating block and the second guide rail during transverse prestress tensioning
End is connected between outside portion by hinge, and second guide rail can laterally rotate around the regulating block.As such, it is desirable to tensioning
When, the second guide rail can be flipped to the outside around the regulating block, operating space is provided to transverse prestress tensioning is carried out, improve
The convenience used.
Lifted for convenience, trolley is slidably fitted with the crane span structure, elevator is installed on the trolley
Machine.
Based on same inventive concept, present invention also offers gantry that the collocation mobile formwork described in a kind of utilization uses
The method that crane system carries out bridge construction, it comprises the following steps：
1）Advance banding steel cage during bridge construction；
2）After exterior sheathing matched moulds, drive device drives inner side running part and outside the running part walking, realizes supporting leg in girder
Moved with the change rail on exterior sheathing, by the hoist engine on crane span structure by the good steel reinforcement cage segmental hoisting of advance colligation to outside
In template；
3）It can carry out carrying out next tying up across steel reinforcement cage while concreting, concreting and maintenance after installation internal model
The mutual aid system devised for poor peasants is made.
It is noted that the girder of the present invention refers to the girder of construction bridges, when using this straddle truck, girder is
The bridge to have completed, exterior sheathing does not play a supportive role to the girder, and is only used as water-bearing concreae when next bridge beam pours
Supporter.
Compared with prior art, the beneficial effects of the invention are as follows：During bridge construction can advance banding steel cage, make after matched moulds
With the present invention four rail gantry crane systems by the good steel reinforcement cage segmental hoisting of advance colligation in place, install internal model after can be mixed
Solidifying soil pours, and concreting works with that can carry out next colligation across steel reinforcement cage while maintenance again, avoids causing worker not busy
Put, make each operation compact neat, the construction period of bridge by 12-15 days of traditional mobile formwork technology/across foreshorten to 7-10 days/
Across significantly shortening total construction period of bridge, bring considerable economic benefit for project.
In addition, the present invention gantry crane system can also be used as poured equipment between bridge and mobile formwork, goods and materials and its
The transfer tool of its building materials.
