Description
Technical field
The utility model relates to the anchor pole of a kind of rotatable break-in and recovery, belongs to technical field of mechanical equipment.
Background technology
Plate brad supporting, bolt support widely use in Foundation Pit Support Engineering and stability of slope engineering, plate brad supporting cost is low, easy construction, but the length of soil nailing and stake diameter less, the equal power of resistance to plucking is little, is only applicable to general stratum, so the scope of application is less, often can not meet design requirement, and this kind of soil nailing can not well Shi Hanzhang, uplift resistance be also strong, can not well play a role; And the equal power of the length of anchor pole, diameter and resistance to plucking is all greater than soil nailing, but its cost is higher, because its intensity, elongation per unit length are all on the low side, and a lot of anchor rod still adopts traditional structure design, in actual applications, the factor impacts such as top board injustice, aperture surrounding rock failure or roof strata move, anchor hole and top board oblique will be caused, top board is uneven, anchor pole is subject to extra shear stress by aperture place, have a strong impact on the performance of bolt support ability, a lot of anchor pole is disrumpent feelings at aperture place, easily causes roof accident.
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 annex building site subterranean excavation constructional difficulties, wastes resource simultaneously.
Utility model content
The technical problems to be solved in the utility model is for above deficiency, the anchor pole of a kind of rotatable break-in and recovery is provided, there is structure simple, easy construction, automatically anchor pole and stabilising arrangement angle can be regulated, reduce the shear stress to anchor pole, anti-pulling capacity is high, long service life and returnable advantage.
For solving above technical problem, the utility model by the following technical solutions:
An anchor pole for rotatable break-in and recovery, comprises anchor pole, stabilising arrangement, fastening devices and protective device, and described anchor pole comprises connecting portion, and the lower end of connecting portion is extended with pars intermedia and bar tip successively;
The outside of described connecting portion is socketed with stabilising arrangement and fastening devices respectively;
Described connecting portion and fastening devices are threaded connection;
The outer cover of described pars intermedia has protective device;
The inwall of described protective device is provided with hangnail clip, hangnail clip be used for by pars intermedia and protective device fastening.
Below the further optimization to such scheme:
The cross section of described stabilising arrangement is arc.
The center of described stabilising arrangement is provided with the through hole for inserting anchor pole.
Described stabilising arrangement is globoidal structure near the part of through hole.
Described fastening devices is provided with the globoidal structure corresponding with stabilising arrangement.
After the utility model adopts above technical scheme, compared with prior art, have the following advantages: the utility model apparatus structure is simple, easy construction; Automatically can regulate anchor pole and stabilising arrangement angle, reduce the shear stress to anchor pole; Anti-pulling capacity is high, long service life, recyclable.
Below in conjunction with drawings and Examples, the utility model is described in detail.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of the utility model device;
In figure,
1-anchor pole, 11-connecting portion, 12-pars intermedia, 13-bar tip, 2-stabilising arrangement, 21-through hole, 3-fastening devices, 4-protective device, 41-hangnail clip.
Detailed description of the invention
Embodiment 1, as shown in Figure 1, the anchor pole of a kind of rotatable break-in and recovery, comprises anchor pole 1, stabilising arrangement 2, fastening devices 3 and protective device 4, and anchor pole 1 comprises connecting portion 11, pars intermedia 12 and bar tip 13;
The outer end of connecting portion 11 is provided with external screw thread;
Connecting portion 11 be externally connected to fastening devices 3;
The outer cover of connecting portion 11 is connected to stabilising arrangement 2;
Stabilising arrangement 2 comprises through hole 21, and through hole 21 is positioned at the center of stabilising arrangement 2;
Anchor pole 1 can be inserted with in through hole 21;
The cross section of stabilising arrangement 2 is arc;
The external surface of stabilising arrangement 2 is globoidal structure near through hole 21 place;
Fastening devices 3 is globoidal structure near one end of stabilising arrangement 2;
The outer cover of pars intermedia 12 has protective device 4;
The inwall of protective device 4 is provided with hangnail clip 41, hangnail clip 41 be used for by pars intermedia 12 and protective device 4 fastening.
The shape of bar tip 13 is cone.
Fastening devices 3 is hexagonal fixture structure away from one end of stabilising arrangement 2.
During use, when anchor pole 1 runs into external force generation skew, fastening devices 3 can rotate to an angle on stabilising arrangement 1, reduces the shear stress suffered by anchor pole 1, prevents anchor pole 1 from damaging.Due to the existence of hangnail clip 41, anchor pole 1 more down moves, tightr with the connection of protective device 4, after using, is extracted by anchor pole 1, and due to hangnail clip 41, anchor pole 1 is separated needs power with protective device 4 is very little, facilitates recovery.
The above is the citing of the utility model preferred forms, and the part wherein do not addressed in detail is the common practise of those of ordinary skill in the art.Protection domain of the present utility model is as the criterion with the content of claim, and any equivalent transformation carried out based on technology enlightenment of the present utility model, also within protection domain of the present utility model.
