Abstract
The invention discloses a kind of clamping structures of anchor pole anti-dropout, including the threaded anchor rod body of rod, it is fixed on the anti-dropout clamping device of anchor rod body end, anti-dropout clamping device front end and threaded anchor rod grafting, the anti-dropout clamping device is the body of rod that upper and lower ends opening is in hollow tubular, the reduced diameter of its front end, the body of rod of hollow tubular are equipped with first axis open slot, and the first axis open slot of the body of rod of front end and hollow tubular symmetrically locate equipped with the second shaft orientation opening groove.The clamping structure of anchor pole anti-dropout is the body of rod that upper and lower ends opening is in hollow tubular, the reduced diameter of front end, when the slit-tube of anchor pole drilling anti-dropout clamping device is extruded into clamping device front end, it can guarantee and be caught in anchor rod body screw thread after drilling squeezes, to avoid anchor pole from falling off from hole in special angle construction, this is simple and practical in structure.
Description
Technical field:
The present invention relates to a kind of constructing tunnel fields, are especially a kind of clamping structure of anchor pole anti-dropout.
Background technique:
The main function that anchor pole plays in constructing tunnel is to improve bearing capacity of the wall rock, forms anchor rod body with country rock
Complex.The anchor pole that is inserted into is easy to fall when tunnel locally carries out armature boring construction, such as after vault drilling, at present such
Problem lacks effective solution scheme.
Summary of the invention:
That the technical problem to be solved by the invention is to provide a kind of structures is simple, anchor pole can be achieved be fixed in hole from
And guaranteeing the clamping structure of the anchor pole anti-dropout of anchoring effect, the clamping structure of the anchor pole anti-dropout is that the safety of anchor bolt construction has
Effect provides safeguard.
The technical solution of the invention is as follows, provides a kind of clamping structure of anchor pole anti-dropout, including the threaded anchor rod body of rod,
It further include the anti-dropout clamping device for being fixed on anchor rod body end, anti-dropout clamping device front end and threaded anchor rod grafting,
The body of rod of the anti-dropout clamping device for upper and lower ends opening in hollow tubular, the reduced diameter in lever front end portion, in
The body of rod of blank pipe shape is equipped with first axis open slot, and the first axis open slot of the body of rod of lever front end portion and hollow tubular is symmetrical
Place is equipped with the second shaft orientation opening groove.
Preferably, the upper end opening of the first axis open slot is greater than lower ending opening.A kind of specific embodiment.
Preferably, the upper end opening of second shaft orientation opening groove is greater than lower ending opening.
Preferably, the gap of the first axis open slot is greater than the gap of the second shaft orientation opening groove of front end.
Preferably, anti-dropout clamping device is made for metal material.Effect is good.
It is after using the above structure compared with prior art, the invention has the following advantages that anti-in the grafting of anchor rod body end
Fall off clamping device, when the slit-tube of anchor pole drilling anti-dropout clamping device is extruded into the front end by clamping device
Guarantee to be caught in anchor rod body screw thread after drilling squeezes, so that anchor pole is avoided to fall off from hole in special angle construction, the knot
Structure is simple, practical, realizes that anchor pole is fixed on safely and effectively providing safeguard for anchor bolt construction in hole.
Detailed description of the invention:
Fig. 1 is usage state diagram of the invention.
Fig. 2 is the sectional view of anti-dropout clamping device of the invention；
Fig. 3 is the sectional view of anti-dropout clamping device of the invention.
Specific embodiment:
Present invention will be further explained below with reference to the attached drawings and specific embodiments:
Embodiment 1, as shown in Figure 1, 2, 3, a kind of clamping structure of anchor pole anti-dropout, including the threaded anchor rod body of rod 1, also wrap
The anti-dropout clamping device 2 for being fixed on anchor rod body end, anti-dropout clamping device front end and threaded anchor rod grafting are included, it is described
Anti-dropout clamping device is the body of rod 3 that upper and lower ends opening is in hollow tubular, the reduced diameter of front end 6, hollow tube
The body of rod of shape is equipped with first axis open slot 4, and the symmetrical place of first axis open slot of the body of rod of front end and hollow tubular is set
There is the second shaft orientation opening groove 5.
The clamping structure of anchor pole anti-dropout is the body of rod that upper and lower ends opening is in hollow tubular, the diameter in lever front end portion by
Tapered small, when the front end of the slit-tube of anchor pole drilling anti-dropout clamping device, anchor pole end is extruded into front end, that is, can guarantee
Drilling is caught in anchor rod body screw thread after squeezing, so that anchor pole is avoided to fall off from hole in special angle construction, structure letter
It is single, practical, realize that anchor pole is fixed on safely and effectively providing safeguard for anchor bolt construction in hole.
Anti-dropout positioning device the preferred metal materials such as iron or steel are made.When anchor pole drilling, slit-tube is extruded,
The main diminishing slit-tube structure by clamping device front end, which can guarantee, is caught in anchor rod body screw thread after drilling squeezes.
Only the preferred embodiment of the present invention has been described above, but is not to be construed as limiting the scope of the invention.It is all
It is the equivalent structure or equivalent flow shift done using description of the invention and accompanying drawing content, is included in patent of the invention
Within protection scope.
