The utility model has the advantages that: the protective layer partition plate designed by the utility model can accurately lift the steel reinforcement cage, and prevent the over-small thickness of the concrete protective layer at one side and the influence on the pile forming quality caused by the non-centered lifting position of the steel reinforcement cage; the utility model discloses a transfer that guide flaring can guide steel reinforcement cage fast.
Description
Technical Field
The utility model relates to a vibration immersed tube bored concrete pile especially relates to an immersed tube bored concrete pile reinforcing bar lifts device.
Background
The pipe-sinking cast-in-place pile is one of many types of pile foundations in civil engineering and building engineering. The method is characterized in that a steel pipe (namely a sleeve) which is adaptive to the design size of a pile is adopted, a pile tip is sleeved on the end part and then sunk into the soil, a steel bar framework is hung in the sleeve, then the pipe is pulled out by vibration or hammering while concrete is poured, and the vibration during pipe pulling is utilized to tamp the concrete to form the required cast-in-place pile. And because the mouth of pipe of immersed tube is less at the framework of steel reinforcement hoist and mount in-process, can't be smooth hoist the framework of steel reinforcement and put to the immersed tube in, if it is great to hoist and put positional deviation, collide with the immersed tube mouth of pipe, will cause the damage to the immersed tube mouth of pipe, in addition when the framework of steel reinforcement is hoisted and put to the immersed tube in, can't be accurate align framework centroid and immersed tube centroid, make the concrete protection layer thickness in the framework outside inhomogeneous, the less one side of thickness probably can't satisfy the engineering technical requirement, influence the quality of forming a pile.
In summary, it is very important to find a steel bar lifting device for a cast-in-place bored concrete pile, which can accurately lift a steel bar cage and is convenient for lifting.
SUMMERY OF THE UTILITY MODEL
The utility model aims at overcoming the deficiencies in the prior art and providing a immersed tube bored concrete pile reinforcing bar hoisting device.
The steel bar hoisting device for the immersed tube cast-in-place pile comprises a protective layer partition plate, a lifting ring, a lifting rope, a lifting plate, a crane traction rope and a guide flaring, wherein the lifting rope, the lifting ring and the lifting plate form the hoisting device; the side wall of the immersed tube is provided with a protective layer spacing plate, the upper end of the protective layer spacing plate is connected with a guide flaring, and the flaring is wide at the top and narrow at the bottom.
Preferably, the method comprises the following steps: the preformed groove at the bottom of the guide flaring is spliced with the top connecting bulge on the protective layer partition plate and fixed by the fixing nail.
The utility model has the advantages that:
(1) the utility model discloses a protective layer space bar can accurately hang and put the steel reinforcement cage, prevents that the steel reinforcement cage from hanging the position and not having the centre and causing one side concrete protective layer thickness undersize, influences the pile quality of forming.
(2) The utility model discloses a transfer that guide flaring can guide steel reinforcement cage fast.

Detailed Description
The present invention will be further described with reference to the following examples. The following description of the embodiments is merely provided to aid in understanding the invention. It should be noted that, for those skilled in the art, without departing from the principle of the present invention, the present invention can be further modified and modified, and such modifications and modifications also fall within the protection scope of the appended claims.
The sinking pipe cast-in-place pile steel bar lifting device comprises a protective layer partition plate 35, a lifting ring 36, a lifting rope 37, a lifting plate 38, a crane pulling rope 39 and a guide flaring 40, wherein the lifting rope 37, the lifting ring 36 and the lifting plate 38 form the lifting device, the lifting plate 38 is connected with a steel bar cage through the lifting rope 37 and the lifting ring 36, and the top of the lifting plate 38 is connected with the crane pulling rope 39; the lateral wall of immersed tube 3 sets up protective layer space bar 35, and guide flaring 40 is connected to protective layer space bar 35 upper end, and the flaring is wide from top to bottom narrow, and the lifting of the steel reinforcement cage of being convenient for is put, and protective layer space bar 35 can make the steel reinforcement cage accurately place, and the concrete protective layer thickness of avoiding both sides is inhomogeneous, influences construction quality.
The preformed groove 41 at the bottom of the guiding flaring 40 is spliced with the top connecting protrusion 42 on the protective layer spacing plate 35 and fixed by the fixing nail 43.
The construction method of the immersed tube filling pile steel bar lifting device comprises the following steps:
(1) and (5) setting a sinking pipe. And (4) utilizing the piling hammer to drive the outer immersed tube to the designed depth.
(2) And (5) hoisting the reinforcement cage. Utilize the loop wheel machine to transfer the steel reinforcement cage that the off-site ligature is good to the immersed tube, need place protective layer space bar 35 at the immersed tube inner wall before putting down to connect guide flaring 40 on the protective layer space bar, the transfer that can effectual guide steel reinforcement cage of guide flaring, the protective layer space bar then can ensure the concrete protective layer thickness of stake not to take place the deviation.
(3) And removing the protective layer spacing plate and the guide flaring on the protective layer spacing plate. And after the steel reinforcement cage is placed, dismantling the protective layer spacing plate and the guide flaring on the protective layer spacing plate.
