Abstract
The invention relates to an anti-floating device for preventing a steel bar cage from floating up. The anti-floating device consists of a steel pipe, three short steel bars, a locked steel bar and three nuts, wherein two of the short steel bars are respectively welded at the bottom end of the steel pipe; a distance between the two short steel bars is 100mm; the top end of the steel pipe is welded with the other short steel bar; each nut is welded on each short steel bar; the two short steel bars at the bottom end form a bayonet structure; the locked steel bar with a bent hook at one end is inserted into the three nuts from top to bottom in sequence; the bent hook of the locked steel bar is hooked on the nut at the top end of the steel pipe. According to the anti-floating device for preventing the steel bar cage from floating up, the two short steel bars arranged at one end of the steel pipe form the bayonet structure which is clamped on a pile steel bar cage reinforcement hoop, so that a pile body can be prevented from floating up during concrete pouring, and an anti-floating effect is achieved; meanwhile, the nuts are welded on the end sockets of the bayonet steel bars in order to prevent a pile steel bar cage from shaking horizontally, and after the locked steel bar penetrates into the bayonet steel bars, a closed space is formed; the anti-floating device is simple and convenient in the conventional construction process.
Description
Technical field
The invention belongs to building engineering field, relate to pile foundation steel bar cage anti-floating and process construction field, specially refer to the anti-floating system that prevents rising of steel cage of Punching Borehole Cast-in-place Concrete Pile.
Background technology
In concrete pouring of punched hole piles process, because 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 in journey upper, concrete produces a kind of active force upwards to pile cages, force rising of steel cage, but in usual work progress, do not take often any measure of anti float, and be under normal circumstances after there is rising of steel cage, simply take manual type adjustment, this effect is mended the fold after the sheep is lost often, for time evening, in construction quality, can not get effective assurance, affected the bearing capacity of pile foundation.
Summary of the invention
Defect and problem that object of the present invention 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, steel pipe bottom forms a bayonet socket, and bottom bayonet socket to be stuck in the stake hoop of putting more energy into upper, can effectively solve the drawback of pile cages floating, this device system can be reused simultaneously, cost-saving.
Technical solution of the present invention is: 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 steel pipe bottom, two bar dowel spacing are 100mm, weld another root bar dowel on steel pipe top, on every bar dowel, weld a nut, two bar dowels of bottom form bayonet arrangement, insert in three nuts from top to bottom successively with the fore shaft reinforcing bar of crotch one end, 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 present invention, at least use two covers device of the present invention.First this device is installed before hole under pile cages, the bayonet socket arranging by steel pipe bottom, being stuck in pile cages puts more energy on hoop, insert after fore shaft reinforcing bar, while preventing concreting, come off, install under rear same reinforcing cage and winch in a hole, after reinforcing cage is issued to design elevation, adopt weight compacting at this device top, prevent rising of steel cage in concreting process; After pile concrete is built, first extract fore shaft reinforcing bar, then twist steel pipe, until bayonet socket position departs 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 feature waiting of construction, is specially adapted in site operation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.In figure: 1-common steel tube, 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 present invention is further described.
As shown in Figure 1, the present invention is made up of a steel pipe 1, three bar dowels 2, fore shaft reinforcing bar 3, three nuts 4, weld respectively two bar dowels 2 in steel pipe 1 bottom, two bar dowel spacing are 100mm, weld another root bar dowel 2 on steel pipe 1 top, on every bar dowel 2, weld a nut 4, two bar dowels 2 of bottom form bayonet arrangement, one end insert successively from top to bottom in three nuts 4 with the fore shaft reinforcing bar 3 of crotch and, 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 present invention, at least use two covers device of the present invention.As shown in Figure 1, first this device is installed before hole under pile cages, the bayonet socket arranging by steel pipe 1 bottom, be stuck in pile cages and put more energy on hoop 5, insert after fore shaft reinforcing bar 3, while preventing concreting, come off, install under rear same reinforcing cage and winch in a hole, after reinforcing cage is issued to design elevation, adopt weight compacting at this device top, prevent rising of steel cage in concreting process; After pile concrete is built, first extract fore shaft reinforcing bar 3, then twist steel pipe 1, until bayonet socket position departs from pile cages, then extract steel pipe, be recycled to next pile cages and again utilize.
The present invention can effectively reduce pile cages rising phenomenon, and the fore shaft arranging by steel pipe bottom is stuck in pile cages and puts more energy into hoop above, inserts after fore shaft reinforcing bar, forms a sealing, reaches pile cages anti-floating effect.The features such as the present invention is reasonable in design, and construction is more simplified, and execute-in-place is convenient, are specially adapted in site operation.
