Abstract
The utility model discloses an add rib formula resistance to plucking stock comprises pole body, floor, stock tray, tray recess and nut. The floor is add at pole body position through at ordinary stock to increase the area of contact of stock and the ground body, improved the defect that smooth round rockbolt anti -drawing force is not enough, not only can strengthen the interlocking effect between stock pole body and the country rock effectively, simultaneously, can improve the whole shear strength of stock, make in the present ground anchor engineering of effect maximize terrain of stock. Withdrawal resistance and shear strength's promotion make carry on the engineering when consolidating the stock figure in the unit area reduce, reduced budget, can bring higher economic benefits.
Description
Technical field
The utility model relate to a kind of can strengthen anti-pulling of anchor bar and rigidity add ribbed Pulling-Resistant Anchor Rod, be particularly useful for the roadway rock reinforce field that rock mass strength is lower.
Background technology
At present; the reinforcing rock bolt shank profile that engineering uses mostly is cylindrical; or periphery is processed with screw thread; this kind of anchor pole in use; usually the anti-pulling of anchor bar after squeezing into can be made not reach desired value because of the problem such as wall rock loosening or mechanically actuated; when particularly setting anchor pole in the country rock that rock strength is lower; be easy to that anchor pole occurs loosen; the phenomenon that even anchor pole comes off occurs; thus cause the action effect of anchor pole greatly to decline; not only waste a large amount of construction materials, the Safety and Quality of returning engineering brings certain impact.
Therefore, need a kind of anchor pole that enough uplift resistances and rigidity can be provided, avoid occurring when surrounding rock consolidation to loosen or dropping situations appearance, to guarantee workmanship, and improve the utilization rate of material.
Summary of the invention
In order to overcome the hypodynamic defect of existing common bolt resistance to plucking, the utility model provides one to add ribbed Pulling-Resistant Anchor Rod, and this anchor pole not only substantially increases the uplift resistance of anchor pole, can also increase shaft rigidity to a certain extent, improve the utilization rate of material.
The utility model solves the technical scheme that its technical problem adopts: on shaft (1), be welded with floor (2), floor (2) is inverted-triangular, one has ten, distribute around shaft (1), the upper-lower position of adjacent two floors (2) has staggered floor, to avoid occurring weak area, by the floor (2) of ten inverted triangle shapes and the interlock action of rock mass, the anti-pulling of anchor bar inserted in rock mass is promoted greatly, not easily occurs to loosen or extract.The side that anchor rod pallet board (3) contacts with rock mass is provided with orthogonal two tray slots (4), when carrying out bolting with wire mesh, vertical tray slots (4) can block steel mesh reinforcement, so both can fixing anchor bar and anchor rod pallet board (3) better, the position that anchor rod pallet board (3) edge also can be avoided to contact with steel mesh reinforcement produces excessive shearing, prevents steel mesh reinforcement from being cut off.After anchor pole squeezes into rock mass, anchor rod pallet board (3) is fixed on rock mass surface by nut (5), and nut (5) utilizes screw thread and shaft (1) to carry out being connected and fixes, during use, by the tightness of rotating nut (5) adjustment pallet, pallet is better contacted with steel mesh reinforcement.
The beneficial effects of the utility model are: by increasing floor (2) on shaft (1), make anchor pole and the soil body produce interlock action, improve the uplift resistance of anchor pole, rigidity also makes moderate progress thereupon, and then improve workmanship, decrease the anchor pole consumption in unit area.

concrete enforcement
In FIG, shaft (1) is welded with floor (2), floor (2) is inverted-triangular, one has ten, and around shaft (1) distribution, the upper-lower position of adjacent two floors (2) has staggered floor, to avoid occurring weak area, by the floor (2) of ten inverted triangle shapes and the interlock action of rock mass, the anti-pulling of anchor bar inserted in rock mass is promoted greatly, not easily occur to loosen or extract.
In fig. 2, anchor rod pallet board (3) is fixed on rock mass surface by nut (5), and nut (5) utilizes screw thread and shaft (1) to carry out being connected and fixes.
In figure 3, nut (5) is hollow hexa-prism, and apparatus can be utilized to rotate nut (5), the tightness of adjustment anchor rod pallet board (3).
In the diagram, the side that anchor rod pallet board (3) contacts with rock mass is provided with orthogonal two tray slots (4), when carrying out bolting with wire mesh, vertical tray slots (4) can block steel mesh reinforcement, so both can fixing anchor bar and anchor rod pallet board (3) better, the position also avoiding anchor rod pallet board (3) edge to contact with steel mesh reinforcement produces excessive shearing, prevents steel mesh reinforcement from being cut off.
Claims (4)
1. add ribbed Pulling-Resistant Anchor Rod, it is characterized in that: be made up of shaft (1), floor (2), anchor rod pallet board (3), tray slots (4), nut (5), floor (2) adopts welding to be connected with shaft (1), and shape is del.
2. according to claim 1ly add ribbed Pulling-Resistant Anchor Rod, it is characterized in that: floor (2) is circular layout on shaft (1), and adjacent two sections of sheet floors (2) are in staggered distribution up and down.
3. according to claim 1ly add ribbed Pulling-Resistant Anchor Rod, it is characterized in that: the side that anchor rod pallet board (3) contacts with rock mass is provided with orthogonal two tray slots (4), can be used for blocking steel mesh reinforcement, anchor rod pallet board (3) edge can be reduced and cut up steel mesh reinforcement.
4. according to claim 1ly add ribbed Pulling-Resistant Anchor Rod, it is characterized in that: anchor rod pallet board (3) is fixed on rock mass surface by nut (5), nut (5) utilizes screw thread and shaft (1) to carry out being connected and fixes, and the tightness of pallet regulates by rotating nut (5).
