Abstract
The invention provides a high-strength pretightening-force yield anchor rod of glass fiber reinforced plastic, which effectively solves the problems of small tensioning force resistance and poor anchoring effect of the original anchor rod. A metal yield ring is arranged between a nut and a tray on an anchor rod assembly. The front end of the anchor rod of glass fiber reinforced plastic is a flat-annular body, and the diameter of the flat-annular body on the front end of the anchor rod is bigger than that of the tail part of the anchor rod. The anchor rod of glass fiber reinforced plastic is effectively prevented from being broken by over-high stress, and the tail part of the rod body is prevented from being broken by applying pretightening force, thereby the torsional resistance of the anchor rod of glass fiber reinforced plastic is improved.
Description
Technical field:
The invention belongs to the new material applied technical field, a kind of specifically novel mine support material.
Background technology:
At present, used bolt support under the coal mine mainly contains screw thread resin anchor, grouted anchor bar, hydraulic type anchor pole, contract seam formula anchor pole etc., but all exists many shortcomings in various degree, and major part all is to make with metal material.In large-scale comprehensive mining machinery coal mining activity, metal material exists and is difficult for cutting, easily produces spark, causes gas explosion and damages the problems such as adopting cutting knife of combining, and uses glass fibre reinforced plastics rockbolts just can effectively solve the problem that belongs to appearance.But the glass fibre reinforced plastics rockbolts that latest developments are got up also exposes the low defective of elongation per unit length.When press in the tunnel, act on the glass fibre reinforced plastics rockbolts, because of producing bigger stretching resistance, to break extremely easily, the ordinary construction glass fibre reinforced plastics rockbolts dare not be exerted oneself when compressing owing to not antitorque, also just can not produce desirable pretightning force, does not reach good anchoring effect.
Summary of the invention:
The invention provides a kind of high-strength pretightening force compressible glass fibre reinforced plastic anchor rod, solved effectively that anchor pole stretching resistance in the past is little, the problem of anchoring effect difference.
The present invention is achieved in that and metal is installed by pressure ring between nut on the anchor pole assembly and pallet, the glass fibre reinforced plastics rockbolts front end becomes flat rounded body, and the flat rounded body diameter of anchor pole front end is greater than the anchor pole tail diameter, and anchor pole can only slide front and back in pallet, can not rotate.
The invention has the beneficial effects as follows: it is disrumpent feelings effectively to have protected glass fibre reinforced plastics rockbolts to be unlikely to the excessive generation of stress, has avoided causing the breakage of body of rod afterbody because of applying pretightning force, thereby has improved the torsional strength of glass fibre reinforced plastics rockbolts.
Description of drawings
Be described further below in conjunction with accompanying drawing
Fig. 1 is a structural representation of the present invention.
Among the figure 1, the glass fiber reinforced plastic body of rod, 2, pallet, 3, allow pressure ring, 4, nut forms
The specific embodiment
During use, punch with jumbolter earlier, again with in the resin anchoring agent load hole, glass fibre reinforced plastics rockbolts etc. is installed in the back, behind the resin solidification, again tray 2, allow pressure ring 3, nut 4, fastening nut 4 is when anchor pole is stressed in the supporting process, allow pressure ring 3 bear pressure from two ends, when pressure acquires a certain degree constantly, allow pressure ring 3 begin distortion, after producing, moves by pallet 2, also make wall produce compressive stress partially, effectively the cover glass steel anchor rod is unlikely to disrumpent feelings because of the excessive generation of pressure, and anchor pole can only slide front and back in pallet 2, can not rotate; When swivel nut 4 applies bolt pretension, the moment of torsion that the anchor pole front end produces is by allowing pressure ring 3 import pallet 2 into, again by pallet 2 and pass to rib, thereby avoided that pretightning force is excessive to cause the breakage of body of rod afterbody because of nut 4 is applied, improved the torsional strength of glass fibre reinforced plastics rockbolts.
Claims (2)
1, a kind of high-strength pretightening force compressible glass fibre reinforced plastic anchor rod is characterized in that, metal is installed by pressure ring between nut on the anchor pole assembly and pallet, and the glass fibre reinforced plastics rockbolts front end becomes flat rounded body, and the flat rounded body diameter of anchor pole front end is greater than the anchor pole tail diameter.
2, anchor pole according to claim 1 is characterized in that, can only slide front and back in pallet, can not rotate.
