Of the existing technology in order to solve the problems, such as, as shown in Figure 1 to Figure 3, the utility model provides a kind of shuttle shape receipts
Contracting formula anchor structure, including anchor rod main body 1, sleeve 4 and multiple shuttle arms 6；
One end of anchor rod main body 1 is equipped with threaded portion, and threaded portion connect with nut 2, and the other end of anchor rod main body 1 is arranged with the
One annulus 8, anchor rod main body 1 pass through sleeve 4；
Sleeve 4 includes perforated steel plate 3, hollow pipe and the second annulus 5, and one end of hollow pipe is connect with perforated steel plate 3, hollow
The other end of pipe is connect with the second annulus 5, and the second annulus 5 is disposed in proximity to the side of the first annulus 8, and perforated steel plate 3 is set to
Side far from the first annulus 8；
One end of shuttle arm 6 is connect with the first annulus 8, and the other end of shuttle arm 6 is connect with the second annulus 5.
In the present embodiment, as shown in Figure 1, anchor rod main body 1 is solid steel column, anchor rod main body 1 and the fixed company of the first annulus 8
It connects, the screw thread being equipped in the anchor rod main body 1 adjacent with the inside of sleeve 4, i.e., the length of threaded portion is according to practical anchor situation
It determines.Hollow pipe and perforated steel plate 3 and the second annulus 5 are by being welded to connect, the preferably circular perforated steel plate of perforated steel plate 3,
Because circular contact area is big, the effect for improving anchor force is best, and the bore dia of perforated steel plate 3 is greater than the straight of anchor rod main body 1
Diameter, less than the outer diameter of nut 2.Nut 2 is disposed adjacent with the perforated steel plate 3 of sleeve 4, and nut 2 is high strength nut, by tightening
Nut 2 drives anchor rod main body 1 to stretch out, and to the thrust that shuttle arm 6 one is inside under the blocking of sleeve 4, shuttle arm 6 is in this thrust
It is softened under effect, that is to say, that push sleeve 4 to strut shuttle arm 6 by tightening nut 2.
Shuttle arm 6 includes two steel pipes and hinge joint 7, and two steel pipes are connected by hinge joint 7.Two steel pipes are square bar
Pipe, hinge joint 7 are pin shaft, and one end that two steel pipes are connect with pin shaft respectively can be rotated around pin shaft, shuttle arm 6 and the first annulus 8

Recycling or replacement.
In the present embodiment, the depth in hole is longer than the length of anchor rod main body 1.When anchoring, as shown in figure 3, by before anchoring
Shuttle shape contraction type anchor structure is put into beaten hole, perforated steel plate 3 be close to the soil body after, by tighten nut 2 push sleeve 4 from
And shuttle arm 6 is strutted, the distracted extruding force of shuttle arm 6 is determined according to the case where anchoring soil body, and anchoring is completed as shown in Figure 1.Work as recycling
It is recycled or is replaced by unscrewing nut 2 when perhaps replacing shuttle shape contraction type anchor structure, shuttle shape contraction type after the recovery
Anchor structure is as shown in Figure 3.Infringement of the anchor pole for a long time in the soil body by water and pH value is corroded, and component performance decline causes
Anchor force decline, the shuttle shape contraction type anchor structure of the utility model is replaced using its recyclable advantage, by anchor force
Bad anchor pole is extracted, and a new shuttle shape contraction type anchor structure is installed at original hole, eliminates the operation of punching
Avoid waste caused by waste anchor rods in the prior art stay in the soil body, waste anchor rods recycle out after become give up into
It is precious.When the gib for pile foundation, existing anchor pole requires slip casting, just loses after the gib that it completes pile foundation
It, which is worth but has infused one entirety of slurry and pile foundation formation due to anchor pole, causes to recycle, and has stayed in and has caused to waste in the soil body, and
The shuttle shape contraction type anchor structure of the utility model may be recovered utilizations after the completion of carrying out gib to pile foundation, saving at
This, reduces resource waste.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all practical at this
Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model
Within the scope of shield.
