Abstract
The utility model discloses an anti-shock anchor bolt, which includes an anchor bar, a fixed sleeve, a connecting sleeve and a connecting ring that can expand in radial direction under an external force. The connecting ring is arranged between the fixed sleeve and the connecting sleeve as well as the connecting sleeve and the connecting sleeve. The fixed sleeve and the connecting sleeve of the utility model are shorter, which are easily inserted into an installing hole; at the same time, the connecting ring can be raised and expended under an external force so that the ring can contact with the installing hole and be pressed tightly in order to fix the anchor bar firmly, which does not shake in radial direction. The fixing accessories of the anchor bar in the utility model is inserted easily, which has a good anti-shock ability and anchor fixing result and especially suitable for the occasion of installing a deep hole.
Description
Technical field
The utility model relates to a kind of crab-bolt, especially a kind of Shock resistant anchor bolt that is suitable under the dark condition of mounting hole.
Background technique
Existing crab-bolt normally by fixed sleeving with anchor rod anchored in mounting hole, under the darker situation of mounting hole, need long anchor pole and fixed muffle, if fixed muffle is made an integral body, to be difficult to be inserted in the mounting hole, especially running under the crooked situation of mounting hole existence, can't install at all.If dwindle its external diameter for fixed muffle being inserted in the tube, will cause rock bolt shank in mounting hole, to occur radially rocking, and then influence the anchoring effect that crab-bolt is treated the anchor object.
The model utility content
At the above-mentioned problem that existing crab-bolt exists under the deep hole situation, the purpose of this utility model provides a kind of promptly being convenient to and installs, and can prevent the Shock resistant anchor bolt that rock bolt shank is radially rocked simultaneously.
For achieving the above object, the utility model Shock resistant anchor bolt comprises: anchor pole, fixed muffle, described fixed muffle comprises cylindrical section and spreading section, the spreading section is sleeved on the anchor pole towards the anchor pole tapered bottom end, process several on the described spreading section along its axial uniform breach, form a spreading sheet between adjacent two breach.
Further, described Shock resistant anchor bolt also comprises at least one coupling sleeve and a connecting ring, the quantity of connecting ring is identical with coupling sleeve quantity, is arranged between fixed muffle and the coupling sleeve and between coupling sleeve and the coupling sleeve, connecting ring under the axial compression situation radial expansion can take place.
Further, have antiskid striped or reticulate pattern on the outer surface of described fixed muffle spreading section.
Further, described connecting ring is made by flexible materials such as plastics.
Further, described connecting ring one end fixes with an end of latch closure mode and described coupling sleeve.
Further, the not closed loop that have opening of described connecting ring for making by metallic material, the top of described fixed muffle cylindrical section is taper, at least one end of described coupling sleeve is taper.
Further, described connecting ring is made by metallic material, comprises top cylindrical section and bottom spreading section, and its spreading section has two spreading sheets at least, and the top of described fixed muffle cylindrical section is taper, and described coupling sleeve one end is taper.
Further, described anchor pole end also has jointing, and this joint one end is by welding or linking to each other with anchor pole threadably, and its other end links to each other with reinforcing bar or other members as anchor point.
Fixed muffle and coupling sleeve in the utility model Shock resistant anchor bolt are shorter, and between fixed muffle and coupling sleeve and coupling sleeve and coupling sleeve, be provided with connecting ring, not only be convenient to the insertion of fixed muffle and coupling sleeve, the spreading section that makes fixed muffle is spreading under external force, simultaneously because connecting ring is subjected to compression swelling, contact and compress with hole wall is installed, make rock bolt shank, can not take place radially to rock by secure fixation.The utility model antidetonation and anchoring effect are good, are particularly useful for the darker situation of mounting hole.

Embodiment
As shown in Figure 1, the utility model crab-bolt comprises: anchor pole 1, coupling sleeve 2, connecting ring 3, fixed muffle 4, the connecting ring 3 that is made of plastics is closed loop, the one end is connected to coupling sleeve 2 one ends in the mode of ring-type buckle, the fixed muffle 4 lower end spreading sections that are made of metal have several spreading sheets, the sleeve stack shell that each spreading sheet is faced between the opening by two two-phases that extend axially suitable distance along fixed muffle 4 constitutes, and the outer surface of spreading section is processed with antiskid striped or reticulate pattern 5.
During use, fixed muffle 4, coupling sleeve 2 and coupled connecting ring 3 are enclosed within on anchor pole 1 shaft successively, subsequently anchor pole 1 are inserted in its mounting hole.From the top coupling sleeve is applied certain pressure, under the effect of this pressure, fixed muffle 4 spreading section pressurized spreadings, together fix in mounting hole with the cone-shaped end of anchor pole 1 lower end, meanwhile, connecting ring 3 is by axial compression and produce radial expansion, and connecting ring 3 outer surfaces after the expansion tightly are pressed against with hole wall is installed on every side, and rock bolt shank and installation hole wall are fixed.
Connecting ring 3 also can be the rectangular closed loop of section that is made of plastics, and is supporting with it with coupling sleeve 2 discrete settings, coupling sleeve 2 end faces and the corresponding plane that is processed as of fixed muffle 4 ear end faces.
As shown in Figure 2, connecting ring 3 can be the trip ring by metal material processing, matches with it, and fixed muffle 4 rear ends are taper, and coupling sleeve 2 at least one ends are taper.
As shown in Figure 3, connecting ring 3 also can be that made by metallic material and the shape fixed muffle structural similarity, and just its sleeve part, spreading section top is shorter.At this moment, fixed muffle 4 rear ends are taper, and coupling sleeve one end is similarly taper.
As shown in Figure 4, anchor pole 1 end also can be provided with jointing, and this joint one end is by linking to each other with anchor pole 1 threadably, and its other end links to each other with reinforcing bar or other members as anchor point.After anchor pole 1 end increases jointing, can make things convenient for the reinforcing bar on the building or the anchoring of other members.
