The specific embodiment
Embodiment 1:
Referring to Fig. 1～2; The present invention includes hoisting frame 1; Operating platform 2, template 3 and be used for the antitorque post 4 of the antitorque combination of flexible sliding formwork comprises cramp bar 5 and connecting rod 6 along the antitorque post 4 of combination of evenly arranging in one week of silo bulkhead; Three cramp bars are arranged into equilateral triangle, are welded into the equilateral triangle lattice column by three connecting rods between three cramp bars.
The spacing of connecting rod is 350～400mm.The reinforcing bar that connecting rod adopts diameter to be at least 20mm is processed.
During practical implementation, emit the barrel sideline in the bulkhead position earlier, the horizontal reinforcement in first section vertical reinforcement of colligation and the template altitude range is is also checked and accepted.Surpass template height of level reinforcing bar and first section later vertical reinforcement, behind template sliding lifting, with sliding with tying up.
Adopt No. 8 iron wires to be connected between template and enclosure.Last enclosure is 240mm apart from template distance suitable for reading, is no more than 250mm.The template end opening with open cabinet frame at the bottom of concordant.Mounting template front template surface should the brushing interleaving agent, installs by the outer order in back in earlier then.The template tapering is an internal mold 0.5%, external mold 0.3%.
Enclosure is locked with the hoisting frame column by the order outside the back in the elder generation, in the elder generation under the back, and enclosure is linked to be integral body.When enclosure is installed, check the level of hoisting frame, vertical and center at any time, and check the spacing of inside and outside enclosure.
According to the sliding formwork design scheme, hoisting frame is installed in design attitude by model.When laying hoisting frame, make each hoisting frame all on same horizontal plane, with its levelness of inspect by instrument such as spirit level and plumb bob, verticality (comprise in the plane, plane outside) and center thereof, carry out support fixation then during installation temporarily.Press the center line symmetry of silo and install, and all install along the silo radial direction.
Operation platform system by inside and outside operating platform, hang scaffold and form, the inside and outside scaffold that hangs should treat that the sliding step heel that rises hangs with peace.
Jack adopts GYD-60 ball-type jack; Cramp bar adopts the flush type cramp bar; Adopt
steel pipe; Be located at the wall center, and use the plummet centering; The joint rate of the cramp bar of jack must not should be less than 1m greater than 25%, two adjacent head height difference on the sustained height.
When cramp bar installation and spreading, requirement is concentric with jack and vertical, and its deviation is not more than 0.5mm.The cramp bar spreading adopts and to add 2 length 200mm diameters of weldering in the steel pipe and reinforce for the 8mm bar dowel, and with electric welding that the groove place weldering of 45 degree is full then, the back polishes off unnecessary weldering meat with hand-held abrasive machine, and rounding is sliding, so that jack passes through.After joint slips over jack, again that the joint area weld all around is firm.
The sliding formwork hydraulic system installs, and should try (before in jack, inserting cramp bar) out, has or not oil impregnate, oil leakage phenomenon in the inspection total system, and whether jack climbs synchronously.Simultaneously to the load condition of part mechanical verification electric power system.Through trial run, could insert cramp bar after all normal.
Just sliding: in template, carry out earlier concrete first pouring, first pouring divides to be carried out for 3～4 times, and every circle is built highly and should be controlled at about 300mm; Build to accomplish and begin just to slide; Sliding rise is 50mm, answers scrutiny concrete depanning situation after the depanning, observes the concrete situation of solidifying; Press bulkhead can extrude finger mark, not cave in finger, use wood float can flatten to normally.Should check comprehensively, adjust the sliding shuttering system immediately after just sliding, change normal sliding the liter stage then over to.The content of inspection comprises: whether template rises even; Form joint has or not distortion, spillage situation; Whether the template gradient is normal; Have or not inclination and distortion after hoisting frame is stressed; Evenly whether enclosure stressed, whether rigidity meets the demands; Whether the operating platform stressing conditions is normal; Cramp bar has or not bending, pulls up phenomenon; Jack, oil connection have or not oil leakage phenomenon; Oil circuit has or not the sliding situation that rises that hinders.Change normal sliding the liter stage after just sliding normally over to, promptly each sliding 300mm that rises.
The initial sliding formwork stage, arrange 3 jack on the cabinet frame opening of per two pilaster centers, be the equilateral triangle line and arrange.Before first envelope mould, remove and to carry out the bottom welding to 3 cramp bars and also need reinforce once after fixing according to 600mm is high; Reinforcing must make 3 cramp bars form 1 independently lattice column; Through forming wholely, so just can effectively control the skew of sliding formwork platform and reverse again with the welding of connecting rod is fixing.
The template climbing speed should specifically be grasped according to the concrete test block situation of condensing of trial-production in early stage.Concrete depanning intensity should be controlled at 0.25～0.4Mpa, promptly presses bulkhead can extrude finger mark, not cave in finger, can hear rustle during template sliding lifting, explains that depanning concrete situation is normal basically.After each template sliding lifting finishes, should in time check depanning concrete situation (finger pressure is examined inspection), build the 300mm that highly must be consistent at every turn, and conscientiously carry out record.Per tour is highly measured once concreting at least, and revises and to build height, accurate with the time that guarantees every layer of depanning and level.The platform level error is allowable variation with at 25mm, wouldn't adjust, and surpasses 25mm and should carry out leveling immediately.Each sliding liter all will accurately be rule, spacing elevated height 300mm with platform erection on cramp bar with level gauge during adjustment.At the sliding climb altitude of adjusting stop according to concrete depanning situation that rises in the process.
Rise in the process sliding, should check the working condition of template system, hydraulic system at any time, to reduce liter poor as far as possible.Poor in order to reduce rising of each jack, can be on every cramp bar certain at interval absolute altitude, alignment target is set; The discrepancy in elevation of adjacent two jack; Generally be not more than 10mm, when promoting at every turn, must make apart from hydraulic control panel jack farthest all rise reach stroke and require after; Can stop pressurization, oil return then; During oil return, also must make the abundant oil return of jack farthest, to rise difference inconsistent in order to avoid cause because of pressurization, oil return are insufficient.
The reason of reversing is various, but is embodied in the inclination that is out cabinet frame inclination or jack, cramp bar in the reality.Therefore, these are reformed could climb smoothly.One, when finding to reverse tendency and torsional amplitude hour, with the pad about 4mm jack is prevented to reverse along the opposite direction bed hedgehopping and continue development, excessively can suitably remove the part pad if find to entangle to turn round, until stablizing; Two, when finding to have tendency reversed and torsional amplitude big, the adjacent cabinet frame of opening is connected with leading chain, lead chain one end and be pulled in out cabinet frame frame leg, the other end is pulled in out cabinet frame frame head piece.Oppositely connect according to torsional direction, when sliding the liter, utilize the slip of opening cabinet frame will lead the chain tension, needn't draw when stopping and leading chain with leading chain.When the revolution tendency, can shed and lead chain.But each action is unsuitable too quickly, and amplitude can not be excessive.Or with built-in fitting under bulkhead skid off the back in time with open the anti-drawknot of cabinet frame top rail, suitably loosen while sliding, make out cabinet frame slowly keep vertical.
In a word, rectify a deviation and turn round all and will carry out with sliding the liter, can not be too quickly, to be controlled to be the master, be auxilliary to entangle.
