Abstract
The utility model discloses a kind of FRP anchor pole locking nut, comprise nut body, described nut body offers interior threaded hole, described interior threaded hole and FRP anchor pole outside thread suitable, the tail end of described nut body is provided with torsion block.The utility model is by adding torsion block structure at the tail end of nut body; destruction torque magnitude is regulated by controlling torsion block thickness; making it be less than, FRP anchor pole is maximum bears torsion; when the coupling mechanism force of nut to anchor rod body reaches destruction torsion; first torsion block can destroy; thus protection FRP anchor pole is not damaged, and substantially increase efficiency of construction.
Description
Technical field
The utility model relates to a kind of FRP (Fiber Reinforced Plastics: fibre-reinforced plastics) anchor pole locking nut.
Background technique
Anchor pole is commonly used to the occasion needing to provide a protective function, and in modern industry, people use FRP anchor pole to carry out stabilization and reinforcement to tunnel construction face gradually, and FRP anchor pole needs to be fixed by nut check.In erecting bed, be manually use torque spanner to lock during nut check mostly, but be difficult to palm torque magnitude when constructing, torsion is too little cannot lock FRP anchor pole, and fragile FRP bolt body that torsion is large, working efficiency is very low.
Summary of the invention
Goal of the invention: the purpose of this utility model is for prior art problem, provides a kind of FRP anchor pole locking nut, both can improve FRP rockbolt installation efficiency, can avoid again damaging FRP bolt body.
To achieve these goals, the utility model have employed following technological scheme: a kind of FRP anchor pole locking nut, and comprise nut body, described nut body offers interior threaded hole, described interior threaded hole and FRP anchor pole outside thread suitable, the tail end of described nut body is provided with torsion block.
In the utility model, preferably, described nut body adopts fiber reinforcement thermosetting molding material to make.
In the utility model, preferably, described nut body tail end is hexahedron shape.
Beneficial effect: the utility model is by adding torsion block structure at the tail end of nut body; destruction torque magnitude is regulated by controlling torsion block thickness; making it be less than, FRP anchor pole is maximum bears torsion; when the coupling mechanism force of nut to anchor rod body reaches destruction torsion; first torsion block can destroy; thus protection FRP anchor pole is not damaged, and substantially increase efficiency of construction.
Accompanying drawing explanation
Fig. 1 is main TV structure figure of the present utility model;
Fig. 2 is side-looking structural drawing of the present utility model.
In figure: 1-nut body, 2-torsion block, 3-interior threaded hole.
Embodiment:
Below in conjunction with accompanying drawing the utility model done and further explain.
FRP anchor pole locking nut of the present utility model comprises nut body 1, and described nut body 1 offers interior threaded hole 3, and described interior threaded hole 3 is suitable with FRP anchor pole outside thread, is conveniently connected with FRP anchor pole.Described nut body 1 tail end adopts hexahedron shape, convenient wrench installation, and is provided with torsion block 2 at the tail end of nut body 1, regulates destroy torque magnitude by controlling torsion block 2 thickness, and making it be less than, FRP anchor pole is maximum bears torsion.
Nut body 1 adopts fiber reinforcement thermosetting molding material to be produced by Shooting Technique, and resin material comprises unsaturated resin, epoxy resin, polyurethane resin, and lamination coating comprises glass fibre, basalt fibre, aramid fibre, carbon fiber.First fiber reinforcement thermosetting molding material is joined in injecting machine material tube, injects mould through high pressure, be heating and curing in a mold, move back mould, screw out nut plug, in be formed centrally internal thread, the tail end mouth of a river forms block structure, and cooling, it is shaping that technique terminates nut.
During actual use; artificial force is locked FRP anchor pole; coupling mechanism force acts on nut body 1, and after FRP anchor rod body contacts with torsion block 2, rod end extrudes torsion block 2; coupling mechanism force is delivered on torsion block 2; when coupling mechanism force reach torsion block 2 destroy torsion time, first torsion block 2 can destroy, thus protection FRP anchor pole is not damaged; when can guarantee so manually to exert a force, torsion substantially constant is in a certain fixed value, thus greatly improves on-the-spot efficiency of construction.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
Claims (3)
1. a FRP anchor pole locking nut, comprise nut body (1), described nut body (1) offers interior threaded hole (3), described interior threaded hole (3) is suitable with FRP anchor pole outside thread, it is characterized in that: the tail end of described nut body (1) is provided with torsion block (2).
