Description
Technical field:
The utility model relates to a kind of anchor pole, relates in particular to a kind of stamped thread bearing capacity height, the sticking anchor-hold height of anchor head, easily cutting, corrosion-resistant, in light weight, easy for installation, the novel thick tail full thread formula glass fibre reinforced plastics rockbolts and the annex of flame-retardant and anti-static.
Background technology:
Anchor pole is the most basic ingredient of roadway support in the middle of the contemporary colliery, and he is strapped in the country rock in tunnel together, makes surrounding rock supporting self.
Anchor pole not only is used for the mine now, also is used for engineering, and to side slope, tunnel, dam body carry out active and reinforce.
Anchor pole is as the tensional element that gos deep into the stratum, and an end is connected with engineering structure, and the other end gos deep in the stratum, and whole anchor pole is divided into free section and anchoring section, and free section is meant that the pulling force with anchor pole head place reaches the anchoring body zone, and its function is that anchor pole is applied prestressing force; Anchoring section is meant the zone of cement slurry with presstressed reinforcing steel and soil layer bonding, and its function is with the bonding rubbing action increase of anchoring body and soil layer, increases the pressure-bearing effect of anchoring body, and free section pulling force is reached soil body depths.
Anchor pole can be divided into according to the material of its use: wood bolt, steel anchor rod, glass fibre reinforced plastics rockbolts or the like.
The body of rod stamped thread of existing full thread glass fibre reinforced plastics rockbolts is divided into metal and nonmetal two kinds, and nonmetal screw thread mainly contains three kinds: (1) screw thread and the full thread body of rod are integral, and stamped thread is a body of rod screw thread; (2) the not moulding body of rod one end of impregnation is filled in the stamped thread mould with broken yarn, forms stamped thread; (3) the not moulding body of rod one end of impregnation is filled in the stamped thread mould with molding compound, forms stamped thread.But common nonmetal anchor tail bearing capacity is lower, and stamped thread is easily deviate from from the trunk yarn.
Metal stamped thread bearing capacity height, but be cut with influence to combining to adopt under the coal mine, easily produce spark; Damage cutter; Need anti-corrosion treatment.
The utility model content:
In view of this, the purpose of this utility model provides a kind of stamped thread bearing capacity height, the sticking anchor-hold height of anchor head, easily cutting, corrosion-resistant, in light weight, easy for installation, the novel thick tail full thread formula glass fibre reinforced plastics rockbolts and the annex of flame-retardant and anti-static.
The purpose of this utility model is achieved by the following technical solution:
The utility model discloses a kind of novel thick tail full thread formula glass fibre reinforced plastics rockbolts and annex, comprise the body of rod, be arranged on anchor dish and nut on the body of rod, wherein, the body of rod outside is the screw thread that becomes rule, and pitch equates that the screw thread outside of body of rod afterbody is provided with stamped thread; The anchor dish becomes disc, and the anchor dish is provided with anchor dish hole, and anchor dish hole is tapered; Nut is a tapered cup nut.
The body of rod is the solid body of rod, and the diameter of the body of rod is 16-24mm.
Nut inside is provided with through hole, and through-hole wall is provided with internal thread, and nut is tapered, and the diameter of through hole matches with body of rod stamped thread, and the screw thread form of the internal thread of through hole matches with body of rod stamped thread shape, and nut is taper.
One end of nut is a hexagon, and the other end is conical, and the across flats of hex end is greater than the external diameter of conical end.
The anchor head of anchor pole is the shape of cutting sth. askew.
The good effect of the technical solution of the utility model is:
The body of rod outside of this novel thick tail full thread formula glass fibre reinforced plastics rockbolts and annex is the screw thread that becomes rule, and pitch equates that the screw thread outside of body of rod afterbody is provided with stamped thread; The anchor dish is provided with anchor dish hole, and anchor dish hole is tapered; Nut is a tapered cup nut.So stamped thread bearing capacity height, the sticking anchor-hold height of anchor head, easily cutting, corrosion-resistant, in light weight, easy for installation, the flame-retardant and anti-static effect is fine.

The specific embodiment:
By Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5 and Fig. 6 as can be seen, the utility model discloses a kind of novel thick tail full thread formula glass fibre reinforced plastics rockbolts and annex, comprise the body of rod 1, be arranged on anchor dish 2 and nut 3 on the body of rod 1, wherein, the body of rod 1 outside is the screw thread that becomes rule, pitch equates that the screw thread outside of the body of rod 1 afterbody is provided with stamped thread 4; 2 one-tenth discs of anchor dish, anchor dish 2 are provided with anchor dish hole 5, and anchor dish hole 5 is tapered; Nut 3 is a tapered cup nut.
Be it can also be seen that by Fig. 1 the body of rod 1 is the solid body of rod, the diameter of the body of rod 1 is 20mm.
By Fig. 1 and Fig. 4 as can be seen, nut 3 inside are provided with through hole 6, and the inwall of through hole 6 is provided with internal thread, and the screw thread form of the internal thread of through hole 6 matches with stamped thread 4 shapes, and nut 3 is tapered.
Be it can also be seen that by Fig. 1 and Fig. 4 nut 3 rear portion external diameters are bigger than anchor dish hole 5 diameters of anchor dish 2, under pressure, nut 3 rear portions enter a part in the anchor dish hole 5 of anchor dish 2.
As seen from Figure 5, an end of nut is a hexagon, and the other end is conical, and the across flats of hex end is greater than the external diameter of conical end.
It can also be seen that by Fig. 1 the anchor head of anchor pole 1 is the shape of cutting sth. askew.
Stamped thread 4 on the body of rod 1 is that the end at the in type body of rod wraps up with molding compound, and mold pressing stamped thread 4 in stamped thread 4 moulds by the frictional force of body of rod screw thread, improves the bonding force of the molding compound and the body of rod 1 then; When assembling is used, on the body of rod 1, be positioned at the stamped thread 4 end socket anchor dishes 2 of afterbody, the nut 3 of screwing at anchor dish 2 rear portions, under the situation that has ambient pressure to exist, the conical end of nut 3 forces to be clamp-oned in the anchor dish 2, improves the prestressing force of glass fibre reinforced plastics rockbolts.
