Description
Technical field
The invention belongs to technical field of buildings, relate to a kind of pipe die and tear fixed charge method end plate primary nut machine open.
Background technology
Existing prefabricated pile or pile tube are as follows in production technology:
1. the metering of concrete raw material, stirring.According to the match ratio designed, by sand, stone, cement, water, additive and admixture etc. through accurate measurement, making the fresh concrete of the low slump of 3cm～5cm with concrete forced mixer, designing requirement strength grade of concrete is not less than C60 or C80.
2. offcenter squared pile end plate makes.Make basically identical with pile end board, but the end plate profile of square pile is square, and the counterbore of the main muscle of prestressing force is uniformly distributed along end plate four limit, angle.Before end plate is installed, the barrette cuff that the sheet metal that surrounding needs throat thickness to be 1.5mm～2mm is fabricated to.
3. carcasing.The main muscle of prestressing force adopts the steel bar for prestressed concrete of underrelaxation type, it is necessary to accurate fixed-length, cut-out, heading；Spiral bar adopts the low-carbon (LC) cold drawn wire of vertebra 4mm～6mm；According to offcenter squared pile structural reinforcement designing requirement, square framework of steel reinforcement adopts special square pile skeleton automatic welding machining.
4. framework of steel reinforcement is installed.The framework of steel reinforcement made, square endplate are welded cuff be positioned in the steel mold of offcenter squared pile, and be connected with deformed bar anchor plate, stretch board, tension rod etc..
5. concrete distributing.By the consumption requirement of every offcenter squared pile, fresh concrete is uniformly filled up along mould female die, many as far as possible some concrete of cloth in stretch-draw one end.
6. matched moulds.Offcenter squared pile upper half punching block is winched to above lower half punching block, and with bolt, upper and lower two halves punching block is fixed, to guarantee that mould does not loosen and concrete not running pulp in high speed centrifugation operation process.
7. prestressed stretch-draw.Offcenter squared pile framework of steel reinforcement after matched moulds is carried out integral tension by the stretching machine adopting jack type, after being stretched to the 70% of reinforced steel bar strength, is fixed in steel mold by tension rod with big nut.
8. centrifuging process.Winching to above centrifuge by the band mould offcenter squared pile after above-mentioned stretch-draw anchor, accelerate step by step by initial velocity, middling speed, high speed, centrifugal speed at a high speed, centrifugation time is generally 10min～18min.By centrifugal closely knit moulding process, making fresh concrete uniformly closely knit along the mould surrounding of offcenter squared pile, meanwhile, pile tube forms a round cavity.After centrifugal end, stretching end is raised, topple over the useless pulp-water produced in centrifugal process.
9. primary steam curing.Being winched to by band mould offcenter squared pile after centrifugal forming in atmospheric steam curing pool hole, quiet stop 1h～2h, be to slowly warm up to 90 DEG C～100 DEG C, under normal pressure, maintenance 4h～8h, makes concrete strength reach more than 40MPa.
10. the demoulding.Band mould offcenter squared pile after primary steam curing is winched on special stripping station position, sheds stretch-draw bolt and die bolt with pneumatic impact wrench, to pile body Shi Hanzhang, then hang away upper mold section, stir female die, shed prestressing force and widen screw rod.Female die, anchor plate, tension rod in cleaning, and brushing releasing agent.It is the offcenter squared pile of C60 for concrete design strength grade, the offcenter squared pile after the demoulding is directly hoisted to finished product stockyard Ma Dui, natural curing, can dispatch from the factory after the intensity that reaches to dispatch from the factory.
11. high-pressure steaming and cultivating.Design strength grade of concrete is the offcenter squared pile of more than C80, offcenter squared pile after the demoulding need to being entered back into autoclave and carry out high-temperature vapour maintenance, maximum temperature is 180 DEG C～200 DEG C, and saturation vapour pressure is 1.0MPa, curing time 8h～12h, makes concrete strength reach more than 80MPa.Pile tube after high-pressure curing can directly dispatch from the factory for stake.
Wherein, in knockout course, prior art is to shed stretch-draw bolt with pneumatic impact wrench, that is to say the primary nut removed on fixed charge method end plate, and this working method is inefficient, is not suitable for the requirement of automated production.
