Description
Technical field
This utility model relates to the high pre-stress anchor pole of a kind of band expansion sleeve, belongs to anchor pole field.
Background technology
The great development built along with China super expressway, the demand that complicated landform builds highway in mountain region, plateau etc. increases year by year, and wherein slope retaining application is quite varied.Although substantially but still there is drawback in the most commonly used various anchor pole effects.It is mainly manifested in: one, trouble, cost height are installed；Two, there is no initial tensile strength；Three, long-acting high pre-stress cannot be realized.The expansion type roof bolt that such as 201510219653.3 utility model patents are proposed devises a kind of expandable anchor sleeve, but owing to the anchor sleeve whole anchor pole of covering causes its length long thus causes the waste of material.
To sum up, be presently required according to existing construction technology level provide a kind of more economical, there is the anchor structure of more efficient high pre-stress.
Summary of the invention
This utility model provides the high pre-stress anchor pole of a kind of band expansion sleeve, the problem high for solving present installation cost.
The technical solution of the utility model is: the high pre-stress anchor pole of a kind of band expansion sleeve, including anchor rod body 1, anchor pole head 1a, spiral thread on anchor bolt portion 1b, bolt expansion set 2, open slot 2a, anchor pole sleeve pipe 3, anchor rod pallet board 4, injected hole 4a, nut 5；
Described anchor rod body 1 one end is anchor pole head 1a, the other end is spiral thread on anchor bolt portion 1b, centre passes sequentially through bolt expansion set 2, anchor rod body 1 is entangled by anchor pole sleeve pipe 3, anchor rod pallet board 4, and spiral thread on anchor bolt portion 1b is threaded connection through anchor rod pallet board 4 with nut 5, and anchor rod pallet board 4 is provided with injected hole 4a；
Described anchor pole head 1a is reverse wedge shape, and its head maximum gauge is more than the diameter of bore of described bolt expansion set 2.
Described bolt expansion set 2 has multiple open slot 2a axial along anchor pole near anchor pole head 1a one end.
Work process of the present utility model is:
Anchor pole already equipped with bolt expansion set 2 and anchor cable sleeve pipe 3 is put into (anchor cable sleeve pipe 3 is used for propping up bolt expansion set 2, anchor rod pallet board 4) in the hole being drilled, then tightening nut 5, when anchor pole head 1a produces relative slip with bolt expansion set 2, bolt expansion set 2 is expanded by the expansive force of anchor pole head 1a, bolt expansion set 2 and hole wall produce powerful frictional force and form self-locking, then pull down anchor pole sleeve pipe 3 again by injected hole 4a slip casting in hole, to be solidified after can improve anchor force thus reach to improve the effect of anchor rod prestress.
The beneficial effects of the utility model are:
1, the anchor structure of the Novel belt expansion sleeve of a kind of suspension roof support is provided, it is achieved while high pre-stress, ensure that the anchor force of anchor pole；
2, the processing of bolt expansion set is simple, reusable anchor sleeve tube coupling cost-saving high financial profit；
3, provide higher prestressing force, anchor pole distribution density can be reduced under equal supporting condition and then reduce construction workload.
