Summary of the invention
The object of the invention is to provide a kind of pile foundation reinforcement cover adjusting device, and these device mounting or dismounting are convenient and swift, and minimizing personnel, equipment investment, reduce investment outlay.
The object of the present invention is achieved like this: a kind of pile foundation reinforcement cover adjusting device, this device comprises that hydraulic jack, iron chain type reinforcing bar hook and three-jaw roof draw agate, iron chain type reinforcing bar hook is arranged on the monosymmetric position of hydraulic jack, takes weld connection; Three-jaw roof draws agate to be arranged in hydraulic jack.
Described three-jaw roof draws agate 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, and totally three, be 120 degree angles and be uniformly distributed, be welded on the top, center of base by welding manner, become 60 ° of angles with base plate, between three feets, be welded with stiffened panel, play 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, is welded on the below, center of base.
Three-jaw roof draws agate 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 manually by house, bridge pile foundation reinforcement cover adjusting device takes the position that needs to adjust pile foundation reinforcement cover in Pile-Well to, feet three legs are 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, make reinforcement cover 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 the quality of pile foundation reinforcing bar, guarantee follow-up concrete pouring quality, ensure workmanship.Handling safety, reliable, convenient, cost-saving.
This device can all Pile-Well steel bar cage protecting layer be adjusted to the right place pile foundation reinforcement cage hoisting at 3 ~ 5 hours at crane after in Pile-Well; greatly shorten activity time, accelerated programming, and solved pile foundation steel bar cage part and occur 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, reduction personnel 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.
Brief description of the drawings
Below in conjunction with drawings and Examples, the invention will be further described:
Fig. 1 is setting device of the present invention location schematic diagram.
Fig. 2 is adjusting device overall structure schematic diagram of the present invention.
