Description

Hollow barb anchor rod

Technical Field

The utility model relates to an stock field especially relates to a cavity barb stock.

Background

The stock is the main atress member of supporting system is consolidated to the ground body, and current stock is of a great variety, but all has some common problems, and when the ground body produced the motion, the stock produced the slip easily, leads to the fixed ability of stock to weaken gradually, finally leads to the stock to lose reinforced ability.

SUMMERY OF THE UTILITY MODEL

To the above problem, the utility model provides a cavity barb stock has the not hard up advantage that leads to losing the reinforcing ability of stock that prevents.

The technical scheme of the utility model is that:

the utility model provides a cavity barb stock, includes base and screw rod, and the base is open-top's cavity structure, and its inner wall is equipped with the internal thread, the screw rod is both ends open-ended cavity structure, the screw rod with the internal thread screw-thread fit of base, the lateral wall of base is opened along the length direction of screw rod has two relative logical grooves, and this logical groove link up the inside and the outside of base, the inner wall of base is equipped with a pin joint, and this pin joint equals apart from the distance in two logical grooves, it has two barbs that are relative motion to articulate on the pin joint.

The working principle of the technical scheme is as follows:

connect base and rope through the screw rod, set up mobilizable barb on the base, the barb is when getting into the ground body, be in the draw-in state, after getting into the ground body, utilize the through-hole that the instrument passes through the screw rod middle part to expand the barb, the barb is in the grout after the internal expansion of ground, make the stock at the internal reinforcement of ground, and simultaneously, even the ground body takes place to become flexible, the stock that is equipped with the barb can not remove along with the not hard up of ground body, consequently, when the ground body produces the motion, the stock produces easily and slides, the fixed ability that leads to the stock weakens gradually, finally lead to the stock to lose the problem of reinforcing ability.

In a further technical scheme, the hollow barb anchor rod further comprises a rope fastener, and the rope fastener is arranged at the end part, far away from the base, of the screw rod.

In a further technical scheme, the barbs are V-shaped with included angles larger than or equal to 135 degrees, and the two barbs are hinged to the hinged point to form a Y shape.

The utility model has the advantages that:

1. the base is connected with the rope through the screw, the movable barbs are arranged on the base, the barbs are in a furled state when entering a rock-soil body, the barbs are unfolded through the through holes in the middle of the screw by using an instrument after entering the rock-soil body, and the barbs are grouted after being unfolded in the rock-soil body, so that the anchor rod is reinforced in the rock-soil body;

2. the anchor rod and the rope for fixing the rock-soil body are fixed by the rope buckle, and the rope buckle is in threaded connection with the screw rod, so that the distance between the rope buckle and the surface layer of the rock-soil body can be adjusted according to actual use requirements;

3. the V-shaped barbs can be unfolded towards two sides of the cavity under the action of the tool, and when the V-shaped barbs are folded, gaps are formed among the barbs, so that space is provided for pushing the tool;

4. the two sides of the cavity are respectively provided with an agnail, and the agnail is unfolded from the two sides of the cavity, so that the two sides of the anchor rod are uniformly stressed, and the anchor rod is prevented from deviating to a certain direction;

Description of reference numerals:

10. a rope fastener; 20. a screw; 30. connecting the internal threads; 40. a barb; 50. a base.

Detailed Description

The embodiments of the present invention will be further explained with reference to the drawings.

Example (b):

as shown in fig. 1-3, a hollow barb anchor rod comprises a screw rod 20, a base 50 and barbs 40, wherein a cylindrical through hole is axially formed in the screw rod 20, the base 50 is cylindrical, a countersunk screw hole is formed in one axial end of the base 50, one end of the screw rod 20 is in threaded connection with the end of the base 50, the axis of the base 50 is collinear with the axis of the screw rod 20, a through groove with two opposite sides is formed in the other end of the base 50, two barbs 40 are arranged in the through groove, one end of each barb 40 is hinged to the inner wall of a cavity, the other ends of the two barbs 40 point to the end of the base 50 where the screw rod 20 is arranged, meanwhile, a gap is formed between the ends of the two barbs 40 pointing to the screw rod 20, and after the anchor rod is installed, the cavity in the base;

when the anchor rod is used, a rope for fixing the protective net is fixed on one end of the screw rod 20 far away from the base 50, meanwhile, the base 50 and one end of the barb 40 are embedded into the rock-soil body, then a tool is used for spreading the two barbs 40 in the base 50 through the through holes in the screw rod 20, and finally, grouting is carried out on the rock-soil body provided with the anchor rod, so that the anchor rod is fixed in the rock-soil body;

through above-mentioned technical scheme, when the ground body takes place not hard up, the stock that is equipped with barb 40 can not remove along with the not hard up of ground body, has solved when the ground body produces the motion, and the stock produces the slip easily, leads to the fixed ability of stock to weaken gradually, finally leads to the stock to lose the problem of reinforced ability.

In another embodiment:

one end of the screw rod 20 far away from the base 50 is connected with a rope fastener 10, the anchor rod and a rope for fixing the rock and soil body are fixed by the rope fastener 10, meanwhile, the rope fastener 10 is in threaded connection with the screw rod 20, and therefore the distance between the rope fastener 10 and the surface layer of the rock and soil body can be adjusted according to actual use requirements.

In another embodiment:
