The movable bearing support of upper beam 5 after support is installed on track 5-1 first, then upper beam after 5 is placed on support Operating position, rear upper beam 5 is steady with sleeper supporting, holds rear upper beam in four direction using 4 3T jacks and consolidates.
4. installing C-type beam 4-5 and main couple 1
First main couple reaction wheel 5-3, jacking cylinder are mounted on main couple in advance in the place of bridge pier lower part, then will C-type beam 4-5 and main couple 1 are assembled, then by more than assembled good 1 integral hoisting to beam portion of C-type beam 4-5 and main couple, It is assembled with the rear upper beam 5 having good positioning, the anchoring sunpender between C-type beam 4-5 and rear upper beam 5 is installed, sunpender upper end connects C-type beam 4-5 flange plate top beam body is connect, lower end connects flange plate lower part C-type beam body, keeps rear upper beam 5 and C-type beam 4-5 secured Hold around in beam body, at the same by near the main couple reaction wheel 5-3 of two sides to drawing finish rolling deformed bar to pass through web and fastening.
5. installing front beam 4-1 and rear upper beam 5
Front beam 4-1 and rear upper beam 5 are lifted on main couple 1, front beam 4-1 and rear upper beam 5 are adopted with main couple 1 With bolt anchor connection, all connection bolts must use high-strength bolt, then install on front beam 4-1 and rear upper beam 5 Finish rolling screw thread sunpender.
6. installing Hanging Basket bottom basket
(1) before Hanging Basket bottom basket being installed, platform assembly Hanging Basket bed die is set up under bridge pier, must assure that in the installation of Hanging Basket bed die Bed die template flatness adjusts the forward and backward crossbeam of bed die in same plane.
(2) two groups of pulley blocks are respectively set in the forward and backward suspension centre of main couple 1, hang wirerope on the forward and backward crossbeam of bed die, so Afterwards with hoist engine lifting bed die to corresponding position, after the completion of lifting, two bottom anchor structures on joist, are then installed after first installing Each suspension centre and articulated mounting on forward and backward crossbeam.
7. installing side form
By side form and edge of a wing truss, assembling is finished in place under bridge, is promoted on the inside of side form to main couple 1 with lifting equipment, It is fixed temporarily, props up and adjust strut.
8. installing internal model skid beam and template
(1) interior skid beam 4-2 is hung in advance to 0# beam section before front beam 4-1 and rear upper beam 5 are installed, using Chain is temporarily fixed steady by two interior skid beam 4-2.Front beam 4-1 and rear upper beam 5 play internal model skid beam after being installed again It hangs, first the rear end interior skid beam 4-2 is mounted on lifting lug, then moving forward interior skid beam 4-2 makes the front end interior skid beam 4-2 and front beam The finish rolling screw thread lifting lug installed on 4-1 and rear upper beam 5 is attached, and completes the installation of internal model skid beam system.
(2) internal model truss is hung piece by piece and is mounted in internal model skid beam, after fixation, block-by-block installs inside molding plate.
9. successively installing each position workbench, guardrail and ladder
10. locking whole sunpenders and suspender belt after adjusting external mold of outer die and internal model absolute altitude
The moving process of descending hanging basket described in the utility model:
The measuring track 5-1 center line on the beam face for poured segment clears up the concrete surface within the scope of track 5-1 Leveling.The connector of adjacent orbit 5-1 should be smooth.Check whether the safety device of each key position when traveling Hanging Basket adds, it is each to sell In place whether the split pin of axis.The sunpender on the forward and backward crossbeam of bed die is loosened, so that bed die system is detached from beam body bottom plate by gravity. Adjusting side mould screw rod outward, and side form template is pulled using jack auxiliary, it is detached from 5~15cm of beam body web, loosens front beam 5~15cm of front overhang sunpender on 4-1 and rear upper beam 5.For anchoring the finish rolling screw thread of main couple 1 on upper beam 5 after after loosening Sunpender releases and locks to the part of main couple 1 in the vertical direction, rear 5 support of upper beam laid down, after slowly releasing main couple 1 The mechanical caging of jacking cylinder is held, jacking cylinder is withdrawn, makes Hanging Basket entire lowering, leans forward, so that the inverse buckling wheel of flange plate bottom With both rail wheel 5-4 of rear 5 lower part of upper beam collective effect, depend on Hanging Basket integrally on beam body top plate and flange plate.? Bolt hangs φ 22.5mm wirerope on hook plate afterwards, and 10 tons of guide chains are respectively installed in two sides wirerope front end.During traveling, left and right two The truss of side will keep synchronous, should suitably slow down close at beam-ends 1m.Traveling in place, after timely installment work anchor and it is rear after on Beam support rises main couple rear end jacking cylinder, loosens inverse buckling wheel.The position adjustment of main couple 1 is correct, it is flat to lift bed die Its rear end anchoring is installed in place by platform.Bottom die platform adjustment is correct, the suspension sunpender of locking front and back upper beam.By outer side mold Plate adjustment is correct, locking suspention, anchor rod.
The utility model built-in fitting is few, from heavy and light, occupy little space, reinforcing bar can be using batch production processing integral hoisting peace The advantages such as precision is high, walking risk is small, easy to operate, construction is rapid are filled, it is applied widely, with certain promotional value and answer With value.
