Description
Technical field
The present invention relates to a kind of technical field of building machinery, be specifically related to a kind of recoverable anchor rod.
Background technology
Building, towards more and more higher trend development, requires also just more and more higher to the infrastructure of building.Anchor pole is one of Important building material of foundation ditch construction, and it directly affects the quality of foundation ditch, and the anti-pulling capacity how improving anchor pole reduces the key factor that anchor pole use amount improves foundation ditch quality.Simultaneously in anchor bolt construction process, anchor bar body is retained in the subterranean excavation of neighbouring construction site, also result in and rebuilds building site subterranean excavation constructional difficulties, waste resource simultaneously.
In order to realize the recovery of anchor bar body, the callable anchor pole of prior art comprises the drill bit of hollow cone body structure and is connected to the auger stem of tubular structure of bit upper end, the top of auger stem is provided with connector, auger stem external surface is provided with protruding helix, the core bar that external diameter is less than anchor pole diameter of bore is provided with in auger stem, the upper end of core bar is fixedly connected in connector, and the lower end of core bar is set to the elastic divarication structure of outside spreading and forms the pyramidal structure with step after making elastic divarication folding structures.It utilizes auger stem and drill bit to drill, then core bar is utilized to extend into the center of anchor pole, the lower end of core bar can be utilized thus to be set to the elastic divarication structure of outside spreading and and to form the operation that the pyramidal structure with step carries out taking out anchor pole after making elastic divarication folding structures, the complete recovery anchor pole of energy simultaneously.There is following defect in this technology: one, this anchor structure more complicated, and cost is high, processing difficulties; Its two, after anchor bolt construction, anchoring dynamics is inadequate, and is difficult to keep original linear state in drilling construction, deadweight and loading process due to anchor pole, and the motion modes such as the rotation thus during anchor recovering are difficult to realize.
Summary of the invention
The technical problem to be solved in the present invention is: provide the recoverable anchor rod that a kind of cost is low, provide larger anchored force.
In order to solve the problems of the technologies described above, the invention provides a kind of recoverable anchor rod, comprise anchor head, wire cable anchor core and anchor core outer tube, anchor core outer tube is set in outside wire cable anchor core, wire cable anchor core and anchor core outer tube are arch, wire cable anchor core two ends are positioned at same one end of anchor pole, anchor head is connected with the crooked position of anchor core outer tube arch, described anchor core outer tube is threaded connection by the split of multistage anchor core outer tube and forms, the forward outer surface of every section of anchor core outer tube split is zigzag, its rear portion is smooth outer surface, laciniation is provided with at the anchor core outer tube of arch and wire cable anchor core junction.
The recoverable anchor rod tool of technique scheme is adopted to have the following advantages: during use, first hole in foundation ditch, this callable anchor pole anchor head is put into boring down, then in boring, cement paste is injected, after cement slurry sets, the two ends of the wire cable anchor core of callable anchor pole carried out stretch-draw simultaneously and fix, the anchor head of anchor pole can be utilized to provide anti-pulling capacity, after finishing using, by one end constraint relief of wire cable anchor core, pulling force is applied at the other end of wire cable anchor core, under the effect of anchor core outer tube, cement slurry does not contact with wire cable anchor core and produces bond stress, therefore can easily wire cable anchor core be reclaimed, little owing to reclaiming pulling force, convenient during recovery, and the rate of recovery is high, simultaneously, by being improved to the structure of split on anchor core outer tube, Split type structure facilitates the assembly and disassembly of anchor pole, and be arranged to zigzag at interval of one section, like this when anti-pulling capacity is high, contribute to wire cable anchor core and provide larger anchored force, and this invention reduces production and maintenance cost, improve the rate of recovery of anchor pole.
Preferably, in order to increase the contact area of anchor head and cement paste, strengthen anchored force further, anchor head cross section is trapezoidal.

Fig. 2 is the structural representation of the embodiment 2 of recoverable anchor rod of the present invention;
Fig. 3 is the structure for amplifying schematic diagram at the hole place of the embodiment 2 of recoverable anchor rod of the present invention;
detailed description of the invention
Below in conjunction with drawings and Examples, technical solution of the present invention is further illustrated:
Embodiment 1
As shown in Fig. 1: the invention provides a kind of recoverable anchor rod, comprise anchor head 1, wire cable anchor core 2 and anchor core outer tube 5, anchor core outer tube 5 is set in outside wire cable anchor core 2, wire cable anchor core 2 and anchor core outer tube 5 are in arch, wire cable anchor core 2 two ends are positioned at same one end of anchor pole, anchor head 1 is connected with the crooked position of anchor core outer tube 5 arch, one end of wire cable anchor core 2 is fixedly installed draw ring 4, conveniently apply pulling force, one end is flexibly connected non-slipping block 3 in addition, after finishing using, directly unload non-slipping block 3, by the recovery of wire cable anchor core 2.Anchor core outer tube 5 is threaded connection by the split of multistage anchor core outer tube and forms, the forward outer surface of every section of anchor core outer tube 5 split is zigzag, its rear portion is smooth outer surface, is provided with laciniation in anchor core outer tube 5 and wire cable anchor core 2 junction of arch.
Embodiment 2
As shown in Figures 2 and 3: in the crooked position providing holes of anchor head 1 with anchor core outer tube 5 arch, hole place arranges contiguous block 6, contiguous block 6 connecting steel wire ropes anchor core 2 and anchor head 1, during use, first hole in foundation ditch, when utilizing this anti-pulling of anchor bar, wire cable anchor core 2 two ends can be fixed simultaneously, anchor head 1 is utilized to provide anchored force better, after anchor pole is finished using, one end of wire cable anchor core 2 can be discharged, anchor head 1 and wire cable anchor core 2 are separately simultaneously, wire cable anchor core 2 is reclaimed by draw ring 4 by the other end at wire cable anchor core 2, because wire cable anchor core 2 overcoat has anchor core outer tube 5, wire cable anchor core 2 and anchor core outer tube 5 can relative slidings, be convenient to reclaim wire cable anchor core 2.
Above-described is only the preferred embodiment of the present invention; should be understood that; for a person skilled in the art; under the premise without departing from the principles of the invention; some distortion and improvement can also be made; these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.
