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The mechanical caging of jacking cylinder is held, jacking cylinder is withdrawn, makes Hanging Basket entire lowering, leans forward, so that the inverse buckling wheel of flange plate bottom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.
