Description

Upstroke movable framework steel bar overall binding lifting construction device
Technical field
The present invention relates to bridge construction technical field, be specifically related to a kind of upstroke movable framework steel bar overall binding lifting construction device.
Background technology
Mobile formwork bridge fabrication machine is that one carries template, utilizes cushion cap or pier stud as supporting, bridge is carried out to the construction machinery of cast in situs.Construction Through Form on Traveler operation is continuous productive process, and operation is followed successively by: 1. mobile formwork via hole, adjust in place; 2. at the bottom of colligation, web reinforcement, arrangement prestress steel bundle; 3. assembled internal mold; 4. colligation roof steel bar, steel strand; 5. build case beam concrete; 6. strong health such as grade; 7. stretch-draw, mud jacking, sealing off and covering anchorage.The construction period of every Kong Liang is about 18 days.Construction Through Form on Traveler operation just must can carry out next process after last process completes.At present, existing cage of reinforcement integral hoisting scheme is: in steel bar binding clamping fixture, tie with reinforcing bar is shaping, and cage of reinforcement is installed truss hoisting increases cage of reinforcement rigidity, by 2 straddle trucks, cage of reinforcement integral hoisting is entered mould.What this scheme was more is applied in the precast concrete beam construction of Liang Chang.If Construction Through Form on Traveler takes this kind of scheme, so straddle truck across construction bridges, and need meet large span, high Clearance requirement, needs under bridge floor, arrange straddle truck walking track simultaneously.This kind of scheme major part situation is difficult to implement, and main cause is as follows: 1. pair straddle truck requires high, must meet the requirements such as large span, large-tonnage, high headroom; 2., when pier stud excessive height, straddle truck cannot meet construction requirement; 3., for straddle truck walking track cannot be arranged under the bridge floors such as offshore construction, construction requirement cannot be met.
Summary of the invention
The present invention, in order to overcome the deficiency of above technology, provides a kind of effective shortening construction period and meets large span, the upstroke movable framework steel bar overall binding lifting construction engineering method of high Clearance requirement and construction equipment.
The present invention overcomes the technical scheme that its technical problem adopts:
The construction equipment of this upstroke movable framework steel bar overall binding lifting construction engineering method, comprise the mold be longitudinally arranged on concrete box girder, longitudinally be installed on the guide rail II on mold, be arranged on mold for cage of reinforcement being transported to the longitudinal conveying device I of upstroke movable framework rear end, be arranged in upstroke movable framework for cage of reinforcement being longitudinally moved to the longitudinal conveying device II in upstroke movable framework from concrete box girder and being used for the cage of reinforcement handling in upstroke movable framework to the handling apparatus in exterior sheathing, the groove matched with cage of reinforcement profile is provided with in described mold, the length of described groove and the interior required case beam quantity length sum of upstroke movable framework match, spacing between two side legs of both sides, described upstroke movable framework rear end is greater than the width of cage of reinforcement.
Conveniently in mold, make cage of reinforcement, also comprise the guide rail I be longitudinally arranged on concrete box girder, tower crane and be installed on the road wheel I of tower crane lower end, described tower crane is positioned at the rear end of mold.
Above-mentioned longitudinal conveying device I comprises the guide rail II being longitudinally arranged at both sides, mold upper end respectively, the lifting truss being positioned at mold upper end and is installed on some jack of both sides, lifting truss lower end respectively, the lower end of described jack is provided with road wheel II, described mold is slided by road wheel II and is arranged on guide rail II, and cage of reinforcement utilizes fastening nuts to be hung on the lower end of lifting truss by screw rod.
Above-mentioned longitudinal conveying device II comprises and is longitudinally installed on guide rail III in upstroke movable framework and some travelling jacks respectively, the both sides, lower end of described travelling jack are respectively arranged with several rows travelling wheel III, and described travelling jack is slided by road wheel III and is arranged on guide rail III.
Above-mentioned handling apparatus comprises the crossbeam I and crossbeam II that are horizontally set at upstroke movable framework rear end and front end, and described crossbeam I and crossbeam II are slidably fitted with lifting overhead traveling crane I and lifting overhead traveling crane II respectively.
In order to prevent interfering, the some supporting legs being arranged in two side leg middle position are installed on the rear end of upstroke movable framework by hinge, the tail end of oil cylinder is hinged to be installed on upstroke movable framework, its piston rod head end is hinged to be installed on middle supporting leg, when the piston rod of oil cylinder all stretches out, described middle supporting leg turns to parallel with concrete box girder.
For the ease of mobile mold, above-mentioned mold is slided by consignment trolley and is arranged on guide rail I.
The invention has the beneficial effects as follows: due to when cage of reinforcement is watered build up concrete box girder time, can carry out at the bottom of colligation simultaneously, the manufacturing process of the cage of reinforcement of web reinforcement, arrangement prestress steel bundle and assembled internal mold so that continue during upstroke movable framework via hole fast the cage of reinforcement made to be transported in exterior sheathing.Achieve synchronization job, the construction period in each hole can shorten about 5 days.Relative to traditional construction technique, do not need straddle truck, therefore meet the requirement of large span, large-tonnage and high headroom.Solve the problem that the straddle truck handling cage of reinforcement traditional when pier stud is too high cannot meet construction requirement.The situation that cannot arrange straddle truck walking track under the bridge floors such as offshore construction is suitable for too simultaneously.
