Further, the top of Bailey beam 5 is provided with transverse distribution beam.
Further, the transverse distribution beam top is provided with longitudinal H profile steel.
Further, the full hall supertronic support 6 buckles supporting structure using disk；The full rod member top of hall supertronic support 6 is with
Portion is provided with adjusting screw rod.
Further, the full hall supertronic support 6 is additionally provided with self-locking device.
In use, whole device is all designed using standard knot, ring flange is assembled, Bolt docking；Steel pipe is 6m standards
3m, 1.5m and 1m steel pipe tender are set up in section, discrepancy in elevation regulation；Steel pipe specification is between D630mm × 8mm, steel pipe joint and two root posts
Connected, connected between connector 3 by 1500mm nodes by connector 3 between transverse direction；Steel pipe joint is vertical, laterally use flange
Disk is docked, and Bolt connection, the docking of oblique use termination steel plate, Bolt connection, rod member interval are padded using 1mm hassock plates；
As shown in figure 3, branch pier top distribution beam 4 and the junction of Bailey beam 5, in the pre-buried outrigger of shelf bracket 11 in the both sides of pier stud 8, shelf bracket
11 lower ends use angle pre-embedded steel slab, and horizontal beam is using pre-buried fining twisted steel 10, the symmetrical tensioning of prestressing force in pier stud 8, it is ensured that
Supporting ＆ stablizing, meets stress requirement；Column sets Bailey beam 5 with the top of shelf bracket 11, and Bailey beam 5 uses standard component, in the same direction
The spacing of two panels Bailey beam 5 is adjusted according to profound arc difference inside and outside bridge floor；Profound arc difference is adjusted in two columns interval；As shown in figure 4,
The position irised out in figure is the poor adjusting position of profound arc；Transverse distribution beam is laid on the top of Bailey beam 5, is easy to bridge top weight to be averaged
It is assigned on column；The longitudinal H profile steel of distribution beam top laying, top sets full hall supertronic scaffold 6 again；Full hall supertronic scaffold
6 buckle supporting structure using disk, and the jacking of screw up and down that disk buckles support can be adjusted up and down, be easy to adjust the inside and outside height of upper mould
Difference；It is poor using profound arc inside and outside the longitudinal pitch adjustment bridge of column, adjust the jacking up and down of crura membranacea hand cradle 6 to adjust using the full hall in top
Choose face or so discrepancy in elevation.
Guizhou Province Kerry to Leishan expressway works lower long slope hinge interchange circle C, the bridge blocks of circle D two are respectively positioned on bar
In La He river courses, relief is big, and maximum pier is high about more than 40 meters, and bridge plane is respectively positioned on circular curve and easement curve, and bridge floor is indulged
Horizontal wall inscription is larger, is limited by river course excessively stream, it is impossible to use full framing system；Utilize steel pipe floor stand and the pattern of Bailey beam
Solve because relief is big in scope residing for bridge, river course excessively stream, pier are higher, be unfavorable for the problem of full framing is set up；
Steel pipe floor stand, because steel pipe post takes ground cotton knot seldom, has substantially no effect on excessively stream in the system of support bottom；Only need
Several strong points are wanted, the influence that physical features injustice is caused can be solved to greatest extent using pile foundation of bearing platform plinth 1, while pile foundation also may be used
Success solves the problem of foundation bearing capacity is uneven, pile foundation deeply in weathered rock formation 2m and more than, foundation bearing capacity, which is met, to be required,
Using effect is as shown in Figure 1；The combination form of the double steel pipe pattern of steel pipe floor stand and unilateral 3 Bailey beams in top, every two
The position of piece Bailey beam lapping ends is to the top of twin columns two of steel pipe post along bridge；The distance between this two panels Bailey beam basis
The design requirement set up can between two-tube along bridge to adjustable range, per adjacent two Bailey beam between distance shorter explanation support
Profound arc is shorter, otherwise profound arc is longer, and this solves the problem of profound arc is poor inside and outside bridge；Full hall supertronic scaffold 6 is used
Disk buckles supporting structure, rod member upper and lower ends be equipped with above and below adjusting screw rod, the cope level of adjusting bracket can be achieved, also just realizes
The regulation of the discrepancy in elevation above and below template, therefore solve bridge or so discrepancy in elevation using the form of jacking up and down of supertronic disk buckle scaffold and ask
Topic；Built using steel pipe post and top and profit is repeated several times using what standard component, easy-to-assemble feature completed all material
With property, rolled steel dosage is greatly reduced；Through Guizhou Province Kerry to Leishan tell highway engineering lower long slope hinge interchange circle C,
The engineering practice data statistics of circle D bridge constructions, circle C, circle D bridges each 2 × 4 16 bridge beams of allying the communists reuse the set twice respectively
System, set up from support, pre-pressing bracket, concrete engineering construction, maintenance, dismounting, again row support set up, pre-pressing bracket share one
Individual month；Concrete engineering construction, maintenance, dismounting, take less than five months, greatly improve construction speed, also greatly drop
Low rolled steel dosage；Undergo rainwater season, it was demonstrated that steel pipe support form is not influenceed by river course excessively stream, safety coefficient is high.
Steel pipe post is set to along longitudinal bridge double steel pipe form by the utility model, is carried out using the spacing between double steel pipe
Become arc regulation；The adjustable scope of outer arc is eliminated in the range of all being produced between this two sections of steel pipe columns along along bridge longitudinal direction；
Top Bailey beam 5 is standard knot, and its length for occupying steel pipe scope determines the length for adjusting profound arc difference, occupies longer, arc length
It is shorter, occupy shorter, arc length is longer；The regulation of the bridge floor discrepancy in elevation is carried out by screw rod of the full hall supertronic scaffold about 6；Screw rod is adjusted
The slope in length and breadth of pavement structure can be adjusted according to design requirement and be molded afterwards；Overall discrepancy in elevation regulation can utilize the pile foundation 1 of bottom
Elevation is adjusted.
The utility model is simple in construction, quick construction, can batch production batch production, it is adaptable to which the support of cast-in-place beam body becomes
Arc, supertronic problem；Efficiency of construction is high, the number of turnover is more, repeatable utilization, low cost.
