Position-limiting action, in rotation, anchorage head rotates anchor pole with anchor pole, and intermediate plate is had no way spreading, and cannot palisades be played with anchoring and made
With.
Summary of the invention
The shortcomings that the utility model is overcome in the prior art provides a kind of translation anti-rotation inverted wedge swelled prestressed anchor
Bar has the characteristics that structure is simple, easy to assembly, quick construction.
The technical solution of the utility model is: a kind of translation anti-rotation inverted wedge swelled prestressed anchor, including anchor pole, rises
Shell, intermediate plate and anti-rotation jacking block;Guide ramp, interior corrugated thread, injected hole and internal concave hopper chute are set on the shell that rises;Described
Be provided with T-type sliding slot in guide ramp, the intermediate plate with rise by shell and connect by T-type sliding slot;The anchor pole by interior corrugated thread with
The shell that rises connection;Two anti-rotation blocks are set in internal concave hopper chute, and the anti-rotation jacking block and anti-rotation block are translatable in internal concave hopper chute.
Further, the anti-rotation jacking block includes mandril and wedge into inclined-plane, is provided with pointed tooth and inclined-plane on the anti-rotation block,
The wedge of the inclined-plane of the anti-rotation block and anti-rotation jacking block is into contact of incline plane.Further, it is set on the mandril of the anti-rotation jacking block
It is equipped with rubber sleeve, anti-rotation jacking block and two anti-rotation blocks are connected in the internal concave hopper chute for the shell that rises by the rubber sleeve.
Further, the guide ramp is inverted wedge structure.
Further, helical teeth is provided with outside the intermediate plate.
Further, the anchor pole is hollow lever.
Compared with prior art, the utility model has the advantages that:
(1) anti-rotation jacking block effectively can place depth to anchor pole and position, and guarantee construction requirement;
(2) rotation stop block header spine can be effectively embedded into ground, play the role of anchoring initial stage anti-rotation;
(3) tensioner process intermediate plate translation is opened, and the entire flank of tooth is contacted with palisades simultaneously, and contact surface is big, the compression with palisades
Greatly;
(4) interior wedge is that T-slot structure is connect with intermediate plate, and easy to assembly, quick, intermediate plate falls off when effectively can avoid being put into;
(5) rise by shell (interior wedge) as inverted triangle structure, prestressing force cinching process, anchorage head and palisades more wedge are tighter, and anchor force is not
It is disconnected to increase.

Specific embodiment
A kind of translation anti-rotation inverted wedge swelled prestressed anchor, as shown in Figure 2, comprising: anchor pole 1, intermediate plate 3, stops the shell 2 that rises
Switch block 4, anti-rotation jacking block 5, rubber sleeve 6 etc., in which:
The anchor pole 1 is the hollow lever with corrugated thread structure, is the connecting piece of entire anchor rod system, passes through the shell that rises
The interior corrugated thread of 2 settings is connect with the shell 2 that rises, and rotation process can push intermediate plate 3 to carry out translation opening.
The skeleton that shell 2 is anchor rod system that rises, structure is as shown in Figure 3, comprising: T-type sliding slot 11, guide ramp 12,
Interior corrugated thread, injected hole, internal concave hopper chute etc., the guide ramp 12 are inverted wedge structure, and tensioner process the more is drawn the more tight;Described
T-type sliding slot 11 is provided in guide ramp 12, intermediate plate 3 falls off when anchor pole 1 can be prevented to be put into bolthole.The shell 2 that rises passes through interior wave
Shape screw thread is connect with anchor pole 1, and anti-rotation block 4 and anti-rotation jacking block 5 are translatable in internal concave hopper chute, and intermediate plate 3 and the shell 2 that rises pass through T-type sliding slot
11 connections can push intermediate plate 3 to be translatable along guide ramp 12 and open, carry out to bolthole ground while anchor pole 1 circumferentially rotates
Tensioner.
As shown in figure 4, being provided with T-type structure on the intermediate plate 3, can be put into the T-type sliding slot 11 of the shell that rises (interior wedge) 2, outside
There is a helical teeth in portion, when preload helical teeth can Hom enter anchor hole ground, play anchorage effect.
As shown in figure 5, the anti-rotation jacking block 5 includes a mandril and wedge into inclined-plane, when anchor pole is inserted into bottom hole, mandril is first connect
Contact hole bottom, subsequent wedge strut anti-rotation block 4 into inclined-plane, effectively can place depth to anchor pole and position, guarantee construction requirement.
As shown in fig. 6, the anti-rotation block 4 has pointed tooth, there is an inclined-plane, the wedge of the inclined-plane and anti-rotation jacking block 5 is into contact of incline plane.
When anchor pole is inserted into bottom hole, pointed tooth is first contacted with bolthole, prevents anchor pole from pre-tightening the rotation of process anchorage head and intermediate plate can not rise
It opens.The head pointed tooth of the anti-rotation block 4 can be effectively embedded into ground, play the role of anchoring initial stage anti-rotation.
The structure of the rubber sleeve 6 is as shown in fig. 7, be used to for anti-rotation block 4 and anti-rotation jacking block 5 being connected to the indent for the shell 2 that rises
In sliding slot, part falls off when anchor pole being prevented to be put into.
As shown in figure 8, the working principle of the utility model are as follows: anchor pole 1 is put into, and when the contact of anti-rotation jacking block 5 bolthole bottom, is prevented
Turning jacking block 5 and presses anti-rotation block 4 to 1 direction of anchor pole, anti-rotation block 4 opens under the effect of oblique component, and the pointed tooth of anti-rotation block is embedded in ground,
Position is in place;Anchor pole 1 is rotated, 1 end face of anchor pole pushes the radial translation of intermediate plate 3 to open and contacts with ground, reach wedge to tensioner,
With the increase of 1 axial pretightening pulling force of anchor pole, intermediate plate 3 the more draws the more tight, plays anchorage effect.
