Detailed description of the invention
Understand for convenient, now along bridge direction be called along bridge to or longitudinally, cross-bridges beam direction is called direction across bridge or laterally.Definition construction direction of advance is front, and after rightabout is.
As the visible Hanging Basket of the present invention of the each figure in Fig. 1～8, it comprises:
Carrying platform, this carrying platform, by the left and right main longitudinal grider 2 that is divided into bridge cross section both sides, connects the first crossbeam 1 of left and right main longitudinal grider 2 mid points, forms with the second cross beam 5 of the end that is connected left and right main longitudinal grider direction of advance side.Wherein, left and right main longitudinal grider 2 bottoms are respectively equipped with diagonal brace, form inverted triangular truss structure with main longitudinal grider 2.Carrying platform also comprises the first upper arm 3 that is arranged at left and right main longitudinal grider mid point and the second upper arm 4 that is arranged at left and right main longitudinal grider rear side.The first upper arm is upwards extended and is bent to form barb-shaped suspension part from residing left and right main longitudinal grider, and suspension part end is provided with the piston shoes 3.1 that are connected with walking mechanism.The-the second upper arm is upwards extended and is bent to form barb-shaped suspension part from residing left and right main longitudinal grider, and suspension part end is provided with road wheel 4.1, the first upper arms and the second upper arm and is fixed on and builds edge-beam, makes left and right main longitudinal grider become the semi girder extending forward.
Template system, comprises that template is (with the control machinery that template is carried out to matched moulds and die sinking operation.Template has comprised edge-beam template 8, diaphragm template, roof plate template, bow member, rod-adjurstable and combined threaded rod etc. specifically.Described edge-beam template system 8 is positioned on the semi girder that left and right main longitudinal grider extends forward.The matched moulds of edge-beam and die sinking operation adopt mechanical system, and without hydraulic way, to prevent the backflow after concreting, can carry out lateral adjustments by rod-adjurstable, template is accurately located, after casting complete, regulate rod-adjurstable to adjust die sinking angle and carry template deadweight.Bow member is connected between two main longitudinal griders by bearing pin.Adjust the camber of vault template by regulating the rod-adjurstable of top rail below.At Hanging Basket begin column until then, can bow member and vault formwork integral be transferred to crossbeam base plate below by 4 punching jack on main longitudinal grider.
Running gear 7, is made up of slide lock device 7.2, hydraulic jack 7.1, walking track 7.3 etc.Walking track is removable, be removably fixedly connected on concreting.When Hanging Basket walking, the liquid oil cylinder that is positioned at walking track top links together the piston shoes in the first upper arm 3.1 and slide lock device 7.2, slide lock device 7.2 is fixed on walking track 7.3, the flexible pushing tow by hydraulic jack 7.1 and and the second upper arm on road wheel 4.1 make Hanging Basket walk and put in place forward.
Suspention fixed system 6, it is arranged on concreting (edge-beam), is made up of supporting seat, counter-force seat, finish rolling deformed bar and nut, jack.Suspention fixed system is for fixed support upper arm.Supporting seat lower end adopts spherical, can adjust voluntarily suspending rod angle, makes each suspension rod stressed evenly.
Construction operation platform (attached not shown), this construction operation platform is built in main longitudinal grider surface, for constructor's operation provides place.
Each step signal that the each figure in Fig. 2～8 is cradle construction, it is existing that details are as follows:
As shown in Figure 2, lay Hanging Basket along cross-section of bridge, prepare to carry out the construction of N sections edge-beam.
7.3 push-and-pulls of walking track are to the N-1 sections edge-beam surface of having built, anchoring.As shown in Figure 4, bow member is transferred; Shown in Fig. 5 and Fig. 6, Hanging Basket is transferred, and makes the first upper arm piston shoes and the second upper arm road wheel contact respectively walking track 7.3, the first upper arm piston shoes and is fixedly connected with hydraulic jack, and the hydraulic jack other end is connected with slide lock device.By suspention fixed system, upper arm is supported to be fixed on and build edge-beam.Carry out N sections edge-beam pouring construction.After reaching requirement stretching force, prepares concrete strength to move basket operation.
Remove the locking of suspention fixed system.As shown in Figure 7, hydraulic jack 7.1 acts on pushing tow piston shoes 3.1, thereby makes Hanging Basket integral forward lead.As shown in Figure 8, hanging basket advancing puts in place to N sections.Remove the locking of slide lock device, reach hydraulic jack pedestal, makes piston rod retraction.
Promote Hanging Basket, promote bow member, carry out the pouring construction of N sections top board and diaphragm.In the pouring construction process of top board and diaphragm, upper arm is not born the overall load of Hanging Basket, and its load supports by pouring into a mould edge-beam suspension system.
In edge-beam pouring construction process, the deadweight of Hanging Basket and the weight of edge-beam load on concreting by the suspension of upper arm, do not need to bear gravity by the hawser of bridge.By above construction sequence, edge-beam and top board, diaphragm be successively construction separately, has well solved the adverse effect of edge-beam prestressing force to top board, has guaranteed that edge-beam prestressing force do not shared weakening by top board, can apply prestressing force to edge-beam more accurately.
