Description
Technical field
The utility model relates to anchor pole technique for fixing, is specifically related to a kind of novel resistance to plucking expandable frictional anchor pole.
Background technology
Anchor pole is the main stressed member of Rock And Soil its support reinforcement system, by the operation of anchoring-bolt system longitudinal pulling force, strengthens the resistance to tension of Rock And Soil itself, reaches the effect that Rock And Soil is stable.Existing anchor pole is varied, but all Shortcomings general character, when Rock And Soil has movement tendency or produces motion, anchor pole and its distortion bad adaptability, anchor pole slip, anchoring ability weakens gradually, finally loses, and anchorage reliability is not high.
Utility model content
(1) technical problem that will solve
In order to overcome prior art deficiency, now propose novel resistance to plucking expandable frictional anchor pole, its resistance to plucking is effective, fixation.
(2) technical scheme
The utility model is achieved through the following technical solutions: the utility model proposes a kind of novel resistance to plucking expandable frictional anchor pole, comprise conehead screwed pipe, expansion tube, inside and outside tooth securing member and anchor pole, described expansion tube is placed on conehead screwed pipe, described conehead screwed pipe end is threaded with the outer tooth end of inside and outside tooth securing member, described anchor pole end is threaded with tooth end in inside and outside tooth securing member, described expansion tube end is provided with a base, be provided with a nut in described base, described nut is rotatably connected on described conehead screwed pipe.
Improve as one, described base profile is square.
As further improvement, in described base, be provided with a hexagon counter sink mated with nut size.
As further improvement, be provided with tapped blind hole in the middle part of described conehead screwed pipe and outer wall is provided with the external screw teeth connected with nut.
As further improvement, be the pipe of continuous print three arc lobe compositions bottom described expansion tube, often adjacent two arc lobe curve places of closing are provided with crack arrest mouth.
(3) beneficial effect
The utility model, relative to prior art, has following beneficial effect:
The one that the utility model proposes novel resistance to plucking expandable frictional anchor pole, anchor pole and conehead screwed pipe is affixed forms entirety, anchor pole produces moment of torsion, and nut is fixed in expansion tube base hexagon counter sink.Expansion tube end is square base, and after boring, hole is irregular cycle, and base contacts with periphery rock-soil layer, and base is subject to rock and soil pressure, produces larger frictional force, not easily moves, static in relative rock-soil layer.Conehead screwed pipe rotates, conehead screwed pipe screw thread and nut thread produce relative friction forces, conehead screwed pipe moves backward along screw thread relative expansion pipe, the conical nose extrusion expansion pipe of conehead screwed pipe, expansion tube ftractures gradually, breach is developed to the heart-shaped front end, expansion tube crack arrest hole of peach, and shearing stress is concentrated, and expansion tube ftractures rapidly.Because expansion tube lobe becomes opening shape closed curve, the diameter of expansion tube bump because of extruding is very large, and expansion tube is three lobe sword shape pipes, the effect that its expansion tube pipe lobe inserts soil layer or rock stratum is darker, the frictional resistance formed is larger, and expansion tube ftractures, anchor hole slip casting, friction anchoring better effects if, anchor pole is not easily pulled out, and plays resistance to plucking effect, because anchor pole is connected with inside and outside tooth securing member, anchor pole can screw out recycling, economizes on resources.

Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
The novel resistance to plucking expandable frictional of one as shown in Figures 1 to 5 anchor pole, comprise conehead screwed pipe 1, expansion tube 2, inside and outside tooth securing member 3 and anchor pole 4, described expansion tube 2 is placed on conehead screwed pipe 1, described conehead screwed pipe 1 end is threaded with the outer tooth end of inside and outside tooth securing member 3, described anchor pole 4 end is threaded with tooth end in inside and outside tooth securing member 3, described expansion tube 2 end is provided with a base 21, be provided with a nut 5 in described base 21, described nut 5 is rotatably connected on described conehead screwed pipe 1.
Wherein, described base 21 profile is square; A hexagon counter sink 211 mated with nut 5 size is provided with in described base 21; Tapped blind hole is provided with and outer wall is provided with the external screw teeth connected with nut 5 in the middle part of described conehead screwed pipe 1; Be the pipe that continuous print three arc lobes 22 form bottom described expansion tube 2, often adjacent two arc lobe 22 curve places of closing are provided with crack arrest mouth 23.
The one novel resistance to plucking expandable frictional anchor pole that above specific embodiment is mentioned, it is when specifically using, first in rock-soil layer, a circular opening is offered, related for conehead screwed pipe 1 expansion tube 2 is put into it together, strike real fixation, base 21 is square, after embedding rock-soil layer, rotational resistance is larger, contact with periphery rock-soil layer, not easily rotate, static in relative rock-soil layer, a torsion is applied to anchor pole 4, the related inside and outside tooth securing member 3 of anchor pole 4 and conehead screwed pipe 1 rotate, nut 5 is geo-stationary in hexagon counter sink 211, conehead screwed pipe 1 relative expansion pipe 2 moves backward along thread direction, conehead screwed pipe 1 base plane extrusion expansion pipe 2, arc lobe 22 opens, full curve extends to crack arrest mouth 23 place, shearing stress is concentrated, expansion tube 2 ftractures rapidly.Due to arc lobe 22 opening shape closed curve, the diameter of expansion tube 2 bump because of extruding is very large, and expansion tube 2 end is three arc lobes 22, the effect that its arc lobe 22 inserts soil layer or rock stratum is darker, the frictional resistance formed is larger, and anchor hole slip casting, reaches good anchoring and resistance to plucking effect; Because anchor pole 2 is connected with inside and outside tooth securing member 3, anchor pole 2 can screw out recycling, economizes on resources.
Embodiment recited above is only be described preferred embodiment of the present utility model, not limits design of the present utility model and scope.Under the prerequisite not departing from the utility model design concept; the various modification that this area ordinary person makes the technical solution of the utility model and improvement; protection domain of the present utility model all should be dropped into; the technology contents of the utility model request protection, all records in detail in the claims.
