Abstract
The utility model relates to an anti-floating device for preventing a reinforcing cage from floating. The anti-floating device consists of a steel pipe, three short reinforcing steel bars, a locking reinforcing steel bar and three nuts, wherein two short reinforcing steel bars are welded at the bottom end of the steel pipe respectively; the distance between the two short reinforcing steel bars is 100 mm; one short reinforcing steel bar is welded at the top end of the steel pipe; each short reinforcing steel bar is welded with one nut; the two short reinforcing steel bars at the bottom end form a bayonet structure; the locking reinforcing steel bar with a hook at one end is inserted into the three nuts sequentially from top to bottom; and the hook of the locking reinforcing steel bar is hooked on the nut at the top end of the steel pipe. The two short reinforcing steel bars are arranged at one end of the steel pipe to form the bayonet structure which is clamped on a reinforcing hoop of a pile reinforcing cage, so that floating is avoided during concrete pouring of a pile body, and the anti-floating effect is achieved. The nut is welded at the end of the bayonet reinforcing steel bar to form a closed space after penetrating the locking reinforcing steel bar, so that left and right shaking of the pile reinforcing cage is avoided; and the anti-floating device is simple and convenient in the common construction process.
Description
Technical field
The utility model belongs to building engineering field, relates to the pile foundation steel bar cage anti-floating and processes construction field, specially refers to the anti-floating system that prevents rising of steel cage of Punching Borehole Cast-in-place Concrete Pile.
Background technology
In the concrete pouring of punched hole piles process, because the concreting mode is different with common stake, its concrete be extend by conduit at the bottom of, by up turning at the bottom of stake; Concrete climbs over journey upper, concrete produces a kind of active force that makes progress to pile cages, force rising of steel cage, yet not taking often any measure of anti float in usual work progress, is generally after rising of steel cage occurs, and simply takes manual type adjustment, this effect is mended the fold after the sheep is lost often, for the time evening, can not get effective assurance on construction quality, affected the bearing capacity of pile foundation.
Summary of the invention
Defective and problem that the purpose of this utility model exists in order to overcome above-mentioned prior art, a kind of anti-floating system that prevents rising of steel cage is provided, adopt more common common steel tube on market, three horizontal bar dowels are set at its two ends, the steel pipe bottom forms a bayonet socket, and the bottom bayonet socket is stuck in stake and puts more energy on hoop, can effectively solve the drawback of pile cages floating, this device system can be reused simultaneously, saves cost.
Technical solutions of the utility model are: a kind of anti-floating system that prevents rising of steel cage, formed by a steel pipe, three bar dowels, a fore shaft reinforcing bar, three nuts, it is characterized in that: weld respectively two bar dowels in the steel pipe bottom, two bar dowel spacings are 100mm, weld another root bar dowel on the steel pipe top, nut of welding on every bar dowel, two bar dowels of bottom form bayonet arrangement, one end inserts in three nuts from top to bottom successively with the fore shaft reinforcing bar of crotch, and the crotch of fore shaft reinforcing bar hooks on the nut on steel pipe top.
Described bar dowel length is 100mm～150mm; The barrel hole size of described nut is 20mm～25mm.
Use the utility model, use at least two cover devices of the present utility model.First this device is being installed before the hole under pile cages, bayonet socket by steel pipe bottom setting, be stuck in pile cages put more energy into the hoop on, after inserting the fore shaft reinforcing bar, come off when preventing concreting, install rear with winching under reinforcing cage in a hole, after reinforcing cage is issued to design elevation, in the compacting of this device top employing weight, prevent rising of steel cage in the concreting process; When pile concrete build complete after, first extract the fore shaft reinforcing bar, then twist steel pipe, until the bayonet socket position breaks away from pile cages, then extract steel pipe, be recycled to next pile cages and again utilize.
This device is simple to operate, has reasonable in designly, and the simple characteristics that wait of construction are specially adapted in site operation.
Description of drawings
Fig. 1 is structural representation of the present utility model.In figure: 1-steel pipe, 2-bar dowel, 3-fore shaft reinforcing bar, 4-nut, the 5-hoop of putting more energy into, the vertical main muscle of 6-stake.
The specific embodiment
By reference to the accompanying drawings the utility model is further described.
As shown in Figure 1, the utility model is comprised of a steel pipe 1, three bar dowels 2, a fore shaft reinforcing bar 3, three nuts 4, weld respectively two bar dowels 2 in steel pipe 1 bottom, two bar dowel spacings are 100mm, weld another root bar dowel 2 on steel pipe 1 top, nut 4 of welding on every bar dowel 2, two bar dowels 2 of bottom form bayonet arrangement, one end inserts in three nuts 4 from top to bottom successively with the fore shaft reinforcing bar 3 of crotch, and the crotch of fore shaft reinforcing bar hooks on the nut on steel pipe 1 top.Described bar dowel length is 150mm; The barrel hole size of described nut is 20mm.
Use the utility model, use at least two cover devices of the present utility model.As shown in Figure 1, first this device is being installed before the hole under pile cages, bayonet socket by steel pipe 1 bottom setting, be stuck in pile cages and put more energy on hoop 5, after inserting fore shaft reinforcing bar 3, come off when preventing concreting, install rear with winching under reinforcing cage in a hole, after reinforcing cage is issued to design elevation, in the compacting of this device top employing weight, prevent rising of steel cage in the concreting process; When pile concrete build complete after, first extract fore shaft reinforcing bar 3, then twist steel pipe 1, until the bayonet socket position breaks away from pile cages, then extract steel pipe, be recycled to next pile cages and again utilize.
The utility model can effectively reduce the pile cages rising phenomenon, by the fore shaft that the steel pipe bottom arranges, is stuck in pile cages and puts more energy on hoop, after inserting the fore shaft reinforcing bar, forms a sealing, reaches pile cages anti-floating effect.The characteristics such as the utility model is reasonable in design, and construction is more oversimplified, and execute-in-place is convenient are specially adapted in site operation.
