Abstract
The utility model relates to a kind of recoverable anchor rod that can form enlarged footing, it comprise the tubulose body of rod and and the anchor head of tubulose body of rod bolt; Wherein, described anchor head comprises anchor head main body, is positioned at anchor head main body and is foremost the conical watch box that creeps into, and is positioned at the arc loose-leaf some with ribbing that creeps into watch box rear, and the end plate triangular in shape that is positioned at arc loose-leaf with ribbing rear; Each arc loose-leaf with ribbing is comprised of loose-leaf board and two longitudinal ribs, and it is articulated and connected by a hinge and a back-shaped buckle and anchor head main body.That the recoverable anchor rod that can form enlarged footing of the present utility model has is simple in structure, the body of rod is recyclable, easy construction, can form rapidly the plurality of advantages such as anchoring ability.
Description
Technical field
The utility model relates to a kind of anchor pole, is specifically related to a kind of recoverable anchor rod that can form enlarged footing, belongs to building unit technical field.
Background technology
At present, the situation of construction work band basement is more and more, and a lot of basements have reached layer 2-3, have brought thus a large amount of bracing of foundation pit workloads.In Area In The Coast of Southeast China, ground shallow weak soil is more general, in Foundation Pit Support Engineering, uses in a large number anchor pole technology.
Anchor pole technology quick construction, cost is lower, in recent years, has also occurred the screwed self-rotary recoverable anchor rod of anchor pole external surface, it is by the guide effect of screw thread, and when to a sideway swivel, anchor pole creeps into, when rotating to opposite side, anchor pole exits, and so realizes the recycling of anchor pole.
But above-mentioned self-rotary recoverable anchor rod, its screw thread processing is trouble, and screw thread effective height can not be too large, otherwise the thickness of screw thread will strengthen, difficulty of processing is higher, and cost increases a lot.Just therefore,, the screw thread of self-rotary recoverable anchor rod external surface is less, and its anchoring ability that can produce is limited.
Therefore, for solving the problems of the technologies described above, necessaryly provide a kind of novel recoverable anchor rod that can form enlarged footing, to overcome described defect of the prior art.
Utility model content
For addressing the above problem, the purpose of this utility model is to provide a kind of structural strength high, and anchored force is large, and the recoverable anchor rod that can form enlarged footing easy to use.
For achieving the above object, the technical scheme that the utility model is taked is: a kind of recoverable anchor rod that can form enlarged footing, it comprise the tubulose body of rod and and the anchor head of tubulose body of rod bolt; Wherein, described anchor head comprises anchor head main body, is positioned at anchor head main body and is foremost the conical watch box that creeps into, and is positioned at the arc loose-leaf some with ribbing that creeps into watch box rear, and the end plate triangular in shape that is positioned at arc loose-leaf with ribbing rear; Each arc loose-leaf with ribbing is comprised of loose-leaf board and two longitudinal ribs, and it is articulated and connected by a hinge and a back-shaped buckle and anchor head main body.
The recoverable anchor rod that can form enlarged footing of the present utility model is further set to: each arc loose-leaf external surface rearward end with ribbing is provided with flange, between the flange of the two arc loose-leaves with ribbing that are oppositely arranged, is connected with elastic rubber strip.
The recoverable anchor rod that can form enlarged footing of the present utility model is further set to: described end plate can be connected on the inner side of longitudinal rib.
The recoverable anchor rod that can form enlarged footing of the present utility model is also set to: described end plate, arc loose-leaf with ribbing are inclined to set with respect to the axis of the tubulose body of rod.
Compared with prior art, the utlity model has following beneficial effect:
1. recoverable anchor rod self rigidity that can form enlarged footing of the present utility model is larger, can directly with jumbolter, pierce the anchoring soil body, do not need first to hole, and rear embedding anchor pole, so construction sequence is few, construction is simple.
2. when the recoverable anchor rod that can form enlarged footing of the present utility model is constructed, described anchor pole creeps into design attitude, apply pretension, described arc loose-leaf with ribbing opens under the effect of soil body resistance and pretension, form an enlarged footing, and the creeping into watch box and can effectively prevent that the soil body in drilling process is to the squeezing of loose-leaf with ribbing of anchor head end, and loose-leaf with ribbing is subject to creeping into the supporting role of watch box after opening, and anchor head can produce larger anchored force.
3. the recoverable anchor rod arc loose-leaf with ribbing that can form enlarged footing of the present utility model is at the flexible rubber strip in external surface flange place, under loose-leaf, there is end plate, in drilling process, can effectively prevent that loose-leaf from damaging because of displacement, anchor head creeps into design attitude, apply pretension, elastic rubber strip, along with loose-leaf with ribbing opens, can open landing naturally.
4. the recoverable anchor rod that can form enlarged footing of the present utility model, after going along with sb. to guard him engineering and finishing, departs from anchor head and the body of rod by rotating backward anchor pole, thereby reclaims the body of rod.
5. the recoverable anchor rod that can form enlarged footing of the present utility model does not need end slip casting, can form rapidly anchored force, is suitable for the urgent reinforcing of the soil body, and the more nervous project of going along with sb. to guard him of duration.

The specific embodiment
Refer to Figure of description 1 to shown in accompanying drawing 4, the utility model is a kind of recoverable anchor rod that can form enlarged footing, and it forms by the tubulose body of rod 1 and with the anchor head 2 of the tubulose body of rod 1 bolt.
Wherein, described anchor head 2 comprises anchor head main body 21, is positioned at anchor head main body 21 and is foremost the conical watch box 22 that creeps into, and is positioned at the arc loose-leaf 23 some with ribbing that creeps into watch box 22 rears, and the end plate triangular in shape 24 that is positioned at arc loose-leaf with ribbing 23 rears.Described end plate 24, arc loose-leaf 23 with ribbing are inclined to set with respect to the axis of the tubulose body of rod 1.
Each arc loose-leaf 23 with ribbing is comprised of loose-leaf board 231 and two longitudinal ribs 232, and it is articulated and connected with anchor head main body 21 by a hinge 25 and a back-shaped buckle 26.
Further, each arc loose-leaf 23 external surface rearward end with ribbing are provided with flange 27, between the flange 27 of the two arc loose-leaves 23 with ribbing that are oppositely arranged, are connected with elastic rubber strip 3.Described end plate 24 can be connected on the inner side of longitudinal rib 232.
