Wing, reinforcing bar annulus and wing bending ring, be provided with between wing bending ring and anchor rod body
Support station post, supporting station post welds together with anchor rod body, and wing bending ring one end is welded on wing
In root, and the hole of the reinforcing bar annulus that spiral-lock is between two supporting station posts, at reinforcing bar circle
Sliding above of ring is set with push wing steel pipe, is 120 degree on the surface of push wing steel pipe and is uniformly distributed
It is welded with reinforcing bar positioning bar；
The Chinese patent of Publication No. CN 201031391 Y discloses a kind of umbrella Pulling-Resistant Anchor Rod.
This anchor pole by power transmission strand cable and lower sleeve portion, low bottom-disc, top bottom-disc, the gimbal lever, from spreader bar group
Become, under a stretching force, the San Yiji gimbal lever and opening from spreader bar, form floor space the thickest
Earth pillar, utilizes the weight of the soil body itself and soil to provide basic institute with the shearing strength of soil itself
The withdrawal resistance needed.
The Chinese patent of Publication No. CN 202559350 U discloses a kind of Pulling-Resistant Anchor Rod, this anchor
Bar body is vertically provided with at least one localizer.Described localizer includes ring bolt body cylindrical
Three positioning convex rings being uniformly arranged in week.Described positioning convex ring is with bolt body for base formation etc.
Waist trapezium structure, is vertically provided with at least one localizer in bolt body, thus improves
Pulling test strength.
What above patent used is all mechanical rock bolt, and its feature is good mechanical property, anchoring
Effective, it is used widely in slope reinforcement and foundation pit enclosure are constructed.But, in reality
In the engineering of border, anchor pole duct inwall is through disturbance, and its Rock And Soil disturbance is relatively violent, anchoring effect
Limiting to very much, easily cause and disengage with Rock And Soil, anchor pole is directly pulled out from duct.Additionally,
The anchoring face of general mechanical rock bolt is less, and the contact surface between Rock And Soil is less, it is impossible to
Meet the engine request under big stress.
In sum, a kind of more effectively anchor pole of exploitation, for slope reinforcement and ground base
Plinth resistance to plucking, anti-floating are necessary.
Summary of the invention
For the drawbacks described above overcoming existing machinery formula anchor pole to exist, this utility model provides one
The mechanical linkage Pulling-Resistant Anchor Rod that simple structure, reasonable stress, quick construction, anchoring effect are splendid.
The technical solution adopted in the utility model is:
A kind of mechanical linkage Pulling-Resistant Anchor Rod, including bolt body, described bolt body includes embedding
Enter the anchoring section in the soil body and for anchoring the free segment of anchoring section, it is characterised in that: described
Anchoring section has a support pallet, the described connecting shaft that is provided centrally with supporting pallet, described
Connecting shaft on be hinged with four anchor rods；Described supports the position of corresponding anchor rod on pallet
Offer the connected pore channel of four through total lengths, in described connected pore channel, be provided with vertical applied force
Main muscle, one end of four main muscle of described vertical applied force is through connected pore channel and respectively with corresponding
Anchor rod middle part connect, the other end upwardly extends composition free segment；Described anchor rod exists
Being close to the bottom surface supporting pallet under the traction of the main muscle of vertical applied force, four anchor rods form cross
Shape structure is also in close contact with Rock And Soil.
Also including billet, on described billet, the position of the corresponding main muscle of vertical applied force offers
Four through holes, and the described main muscle of vertical applied force is fixed on Tu Bi by billet.
In order to ensure that the anchor rod stretched can be positioned in the plane supporting pallet well, often
Root anchor rod is all rigidly connected with a vertical applied force reinforcing bar, is secured under tension prop up
In the plane of bracketing dish, finally after free segment is subject to have opened, four anchor rods launched become
One spider, is in close contact with Rock And Soil, is finally mounted in inside the soil body.
The beneficial effects of the utility model are embodied in:
1, the main muscle of vertical applied force is made up of the mild steel of tension works very well, and anchor rod is perpendicular
To by under the traction of lacing wire, one enlarged footing of flare up, after stretch-draw completes, whole anchor pole is with native
The interphase interaction of body, anchor pole starts to play anchoring, uplift effect.
2, intensity height, good toughness, anchoring effect are good, can be used for dam strengthening, tunnel reinforcement
Deng engineering construction field；There is the advantage such as quick construction, efficient, good endurance.
3, its material stiffness is big, and structural stability is good, and enlarged footing adds anchor pole and Rock And Soil
Between contact area, and then substantially increase the anchor force between itself and Rock And Soil, anchoring
Effect is preferable.
