Description

A kind of big nut provision for disengagement producing tubular pole pipe die

Technical field

The utility model belongs to technical field of buildings, is related to a kind of big nut provision for disengagement for producing tubular pole pipe die.

Background technique

Existing prefabricated pile or tubular pole are as follows in production technology:

1. the metering of concrete raw material, stirring.According to designed match ratio, by sand, stone, cement, water, additive and The fresh concrete of the low slump of 3cm~5cm is made of concrete forced mixer through accurate measurement for admixture etc., if Meter requires strength grade of concrete not less than C60 or C80.

2. offcenter squared pile end plate makes.It is almost the same with pile end board production, but the end plate shape of square pile is rectangular, and The counterbore of prestressing force main reinforcement is uniformly distributed along four side of end plate, angle.Before end plate installation, it is 1.5mm~2mm's that surrounding, which needs throat thickness, The barrette cuff that sheet metal is fabricated to.

3. carcasing.Prestressing force main reinforcement uses the steel bar for prestressed concrete of low relaxation type, needs accurate fixed-length, cuts Disconnected, heading；Spiral bar uses the low-carbon cold drawn wire of vertebra 4mm~6mm；It is rectangular according to offcenter squared pile structural reinforcement design requirement Framework of steel reinforcement is machined using dedicated square pile skeleton automatic welding.

4. installing framework of steel reinforcement.The framework of steel reinforcement made, square endplate the steel that cuff is placed in offcenter squared pile has been welded into In mold, and it is connect with deformed bar anchor plate, stretch board, tension rod etc..

5. concrete distributing.By the dosage requirement of every offcenter squared pile, fresh concrete is uniformly filled up into lower half along mold Mould, in tensioning one end some concrete of cloth as more as possible.

6. molding.Offcenter squared pile upper half punching block is hung to above lower half punching block, blending bolt fixes upper and lower two halves punching block, It is not loosened with to ensure mold in high speed centrifugation operation process and concrete not running pulp.

7. prestressed stretch-draw.Whole is carried out to the offcenter squared pile framework of steel reinforcement after molding using the stretching machine of jack type It draws, after being stretched to the 70% of reinforced steel bar strength, tension rod is fixed in steel mold with big nut.

8. centrifuging process.Band mould offcenter squared pile after above-mentioned stretch-draw anchor is hung to above centrifuge, by initial velocity, middling speed, High speed, the centrifugal speed of high speed accelerate step by step, and centrifugation time is generally 10min~18min.By being centrifuged closely knit molding work Skill keeps fresh concrete uniformly closely knit along the mold surrounding of offcenter squared pile, meanwhile, tubular pole forms a round cavity.Centrifugation terminates Afterwards, stretching end is raised, topples over the waste pulp water generated in centrifugal process.

9. primary steam curing.Band mould offcenter squared pile after centrifugal forming is hung in atmospheric steam curing pool hole, it is quiet to stop 1h~2h is to slowly warm up to 90 DEG C~100 DEG C, and 4h~8h is conserved under normal pressure, concrete strength is made to reach 40MPa or more.

10. demoulding.Band mould offcenter squared pile after primary steam curing is hung on dedicated stripping station position, is unloaded with pneumatic impact wrench Tensioning bolt and die bolt are removed, applies prestressing force to pile body, then hangs away upper mold section, stir female die, shed prestressing force Widen screw rod.Female die, anchor plate, tension rod in cleaning, and brushing release agent.It is C60 for concrete design strength grade Offcenter squared pile, the offcenter squared pile after demoulding is directly hoisted to product stockyard code heap, natural curing reaches after factory intensity i.e. It can dispatch from the factory.

11. high-pressure steaming and cultivating.The offcenter squared pile that strength grade of concrete is C80 or more is designed, it need to be by the centrifugation side after demoulding Stake enters back into autoclave and carries out high-temperature vapour maintenance, and maximum temperature is 180 DEG C~200 DEG C, saturation vapour pressure 1.0MPa, supports Time 8h~12h is protected, concrete strength is made to reach 80MPa or more.Tubular pole after high-pressure curing can directly dispatch from the factory for stake.

Referring to Fig. 7 and Fig. 8, in existing demoulding step, the big nut provision for disengagement of production tubular pole pipe die will be on mold 04 Big nut 03 remove, production tubular pole pipe die big nut provision for disengagement include rack 05, motor 0100, demoulding axis 01, flower Key set 02, shaft coupling 08 and swivel nut 09, wherein motor 0100 and demoulding axis 01 are arranged in rack 05, and the setting of spline housing 02 exists On demoulding axis 01, swivel nut 09 is fixedly connected by shaft coupling 08 with spline housing 02, and when motor 0100 works, motor 0100 passes through Motor output shaft driving demoulding axis 01 rotates in a circumferential direction with respect to rack 05, and demoulding axis 01 drives spline housing 02 to rotate in a circumferential direction, to realize Spline housing 02 drives swivel nut 09 to rotate in a circumferential direction by shaft coupling 08.

As can be seen from Figures 7 and 8, for 09 housing of swivel nut on big nut 03, big nut 03 passes through tension rod 06 and tensioning Plate 07 is fixedly connected, and stretch board 07 is arranged in the die cavity of mold 04, and in swivel nut 09 during rotating in a circumferential direction, swivel nut 09 is driven Big nut 03 is moved towards the direction far from 04 upper head plate 041 of mold.However, existing big nut 03 is often combined with mold 04 Relatively tight, during swivel nut 09 rotates in a circumferential direction, big nut 03 has certain probability to pass through the end plate on tension rod 06 and/or mold 04 041 driven mold, 04 opposing mold support movements, this, which is possible to will lead to mold 04, turns on one's side, thereby result in mold 04 and The damage of stake, or even cause work safety accident.
