In building engineering construction field, current various large-scale houses pile foundation, in big-and-middle-sized bridge pile foundation reinforcement construction, general employing processes pile foundation steel bar cage on the outer level land of Pile-Well, then crane is utilized by pile foundation reinforcement cage hoisting in Pile-Well, the local distortion of pile foundation steel bar cage is there will be in the process of lifting, increase the difficulty that pile foundation steel bar cage adjusts at Pile-Well inner protective layer, Pile-Well steel bar cage protecting layer adopts artificial adjustment to need to spend 3 ~ 5 days and every day is equipped with 3 personnel just can adjust to the right place, or there is the phenomenon that reinforcement cover can not be adjusted to the right place completely in local, cause intractability large, time is long, input cost is high, strengthen labour to drop into, and the quality of pile foundation reinforcement cover can not be ensured, affect the quality of follow-up concreting.
Summary of the invention
The object of the invention is to provide a kind of pile foundation reinforcement cover adjusting device, and the mounting or dismounting of this device are convenient and swift, reduces personnel, equipment investment, reduces investment outlay.
The object of the present invention is achieved like this: a kind of pile foundation reinforcement cover adjusting device, this device comprises hydraulic jack, iron chain type reinforcing bar hook and three-jaw roof and draws horse, iron chain type reinforcing bar hook is arranged on the monosymmetric position of hydraulic jack, takes weld connection; Three-jaw roof draws horse to be arranged in hydraulic jack.
Described three-jaw roof draws horse to comprise feet, and feet is connected with base plate, and base plate is arranged on base, is provided with attaching nut in base.
Feet is L-shaped, totally three, is uniformly distributed in 120 degree of angles, above the center being welded on base, becomes 60 ° of angles, be welded with stiffened panel between three feets with base plate by welding manner, plays reinforcement effect.
Feet top steel plate is dentation, plays anti-skidding effect.
The attaching nut of base plate is connected with base plate by welding manner, below the center being welded on base.
Three-jaw roof draws horse by attaching nut and jack bolt bar close-coupled, forms firm, a stable pile foundation reinforcement cover adjusting device.
Pile foundation reinforcement cover adjusting device provided by the invention, by artificial by house, bridge pile foundation reinforcement cover adjusting device takes in Pile-Well the position needing to adjust pile foundation reinforcement cover to, feet three leg is withstood on Pile-Well retaining wall, and iron chain type reinforcing bar hook balance is hung on the reinforcing bar of required adjustment reinforcement cover, by jacking hydraulic jack, reinforcement cover is made to take the size of requirement to, and at this position pile foundation reinforcing bar and the firm weld holder stud of Pile-Well retaining wall pile foundation, realize the adjustment of pile foundation reinforcement cover, ensure that the quality of pile foundation reinforcing bar, ensure that follow-up concrete pouring quality, ensure workmanship.Handling safety, reliable, convenience, cost-saving.
Pile-Well steel bar cage protecting layer can all be adjusted to the right place at 3 ~ 5 hours after in pile foundation reinforcement cage hoisting to Pile-Well at crane by this device; substantially reduce activity time, accelerate programming, and solve pile foundation steel bar cage local there is the problems such as the phenomenon that reinforcement cover can not be adjusted to the right place completely.
Its Heterosis exists:
1, can Reusability;
2, cost-saving, reduce personnel and drop into;
3, saving of labor, save time, material saving, easy construction, safe and reliable;
4, flexible operation, volume is little, easy to carry, of a tightly knit structure, firm;
5, improve workmanship, speed up the work, improve effect.
