Description
Technical field
The present invention relates to a kind of anchors, can be used for the fields such as anchor bolt supporting, anchor bolt fixation.
Background technique
Anchor bolt is mechanical type anchor bolt and binding type anchor bolt according to different structure form and force-mechanism.It is related with the application
Technology be mechanical type anchor bolt.Anchorage effect is played at once after the installation of mechanical type anchor bolt, therefore in some special requirement of engineering
Mechanical type anchor bolt.
Common mechanical type anchor bolt is typically all to hold anchor structure, i.e., anchor bolt tail portion is passed through the structure anchors such as voussoir, the shell that rises
In foot of hole.Since anchoring is only limitted to foot of hole, in the without hindrance drag in other positions, so anchor force is low, and once hold
Anchor failure, will lose anchor force, it is easy to pull out.
Anchor bolt and the structure of some anchor poles are substantially similar.Such as patent application number 201310289750.0 discloses a kind of spine
Claw soil bolt and its application, it includes a steel pipe, and the outer end of steel pipe is equipped with external screw thread, and equipped with stop grouting plug, support
Disk and nut, which is characterized in that be equipped with injected hole at interval of certain distance on steel pipe, be equipped in the steel pipe walls between injected hole
The front end of steel wire pawl, steel pipe is equipped with conical closure cap.Since interval is provided with steel wire pawl, steel wire pawl has centainly the present invention
Elasticity tension, into soil layer, and can only advance and cannot exit, substantially increase the breakout capacity of anchor bolt.But it is this
Anchor bolt resistance is low, is only used for soil layer.
The anchor rod device applied to civil engineering that such as patent application number 201810152414.4 provides again, is in anchor pole
The lateral wall of ontology (steel pipe) is axially disposed fluted, and pawl is provided in the groove, and the pawl can be turned by pin shaft
It is dynamic to be arranged in the groove；The pawl has outer locking part and an interior driving portion, the interior driving portion be deep into anchor bolt ontology and
Towards the lower end of bolt body, the outer locking part is towards the upper end of bolt body；Driving is additionally provided in the bolt body
Component, the driving component include driving plate and drive rod, and the driving plate is bonded with the inner sidewall of bolt body, the driving
The clamping of the lateral wall of the upper end of plate and drive rod and driving plate can along bolt body axially reciprocating, driving plate and pawl it is interior
Driving portion stretches out groove with the outer locking part for driving pawl rotation to make pawl when driving plate moves upwards is merged；Can effectively it increase
Frictional force between strong anchor pole and stratum, structure is more firm after grouting.Since pawl is a kind of the sharp of limited diameter
Bar construction, so resistance is only limited within the scope of the bending resistance of pawl, greatly reduces the intensity and using effect of anchor pole, and
And structure is complicated.
Summary of the invention
The present invention to solve the above-mentioned problems, proposes a kind of finned high power anchor bolt, while proposing the installation of the anchor bolt
Method.
The technical solution adopted by the present invention is that: a kind of finned high power anchor bolt, comprising: anchor bolt ontology, the anchor bolt sheet
Body is the solid body of rod, and the hole outer segment of the solid body of rod is known as rear end, and rear end is equipped with pallet and fastening nut, which is characterized in that solid
It is equipped with one group of axial notch at interval of certain distance on the hole inner segment of the body of rod, is connected in each axial notch and stretches backwards
Finned；Finned connection type is that the slotting ear structure to match with axial notch is equipped in fin root portion, is inserted by slotting ear
Into in the groove of the solid body of rod, then with pin maintenance；A blocking sleeve is cased on the every group finned subsequent solid body of rod,
Guarantee that finned before using installation end rides on the front port for stopping sleeve；The blocking sleeve is equipped with top pillar,
The previous top pillar for stopping sleeve behind the gap between two finned by withstanding on the blocking sleeve of rear end；When the solid body of rod exists
When pulling under the action of fastening nut to outside hole, finned struts outward under the blocking for stopping sleeve.
Further, finned outer periphery is equipped with zigzag tooth tip, to increase the resistance with hole wall.
Further, there is 2-4 for every group of the axial notch, be evenly distributed on the surrounding of the solid body of rod, 2 whens are distributed in
Solid body of rod two sides, trigonometric expression is distributed in the surrounding of the solid body of rod at 3, and 4 whens are arranged symmetrically in the surrounding of the solid body of rod.
Method for Installation of the invention is to need the place for anchoring or installing anchor bolt to beat anchor hole first, by finned strength
The fastening nut of anchor bolt inverts, and finned of the device is made to be in contraction state, and guarantees that finned end rides over blocking set
On the front port of cylinder；The device is fitted into anchor hole, rear end is exposed, rotates forward fastening nut, the solid body of rod is in fastening nut
Pulled under effect to outside hole, finned stop sleeve blocking under gradually strut outward, be supported on hole wall, more draw support more
Tightly.
The invention has the advantages that finned basal area is big due to using finned realization impedance, endurance is big；By
In being equipped with multiple groups finned, it is achieved that multi-point-anchoring and strong impedance, the external bigger anchor force of power is bigger；Even if finned individual
Global failure problem is also not present in failure；And structure is simple and convenient to operate；The length of the device, diameter and can be finned
Quantity can be designed according to project situation, meet various engine requests.
