Description
Technical field
The present invention relates to anchor rod device, especially a kind of intumescent anchor rod device.
Background technology
For the more flourishing rocky areas in crack, drilling applies anchor pole and fastened, and is a kind of increase rock bulk strength, peak
It is worth the effective way of intensity and residual strength.The application of anchor pole can be such that the rock mass of cranny development fastens to a certain extent as one
Individual entirety, particularly in earthquake-prone region domain, the supporting of rock turns into tunnel, the primary of the side slope security protection of train two and appointed
Business.The protection effect of these region rocks will directly affect the traffic safety of automobile, train.And the injection of anchor pole can improve rock
The globality and intensity of stone, increase internal friction angle, the appearance for the problems such as can effectively preventing falling rocks, landslide.
Existing anchor pole only relies on adhesive and anchor pole is fixed in rock generally without expansion function, because adhesive is change
Synthetic is learned, durability is not enough, and bond effect can decline over time.And intumescent anchor pole is generally that one end is bloomed at present,
And expansion effect is difficult to ensure that.The volume after expansion is only relied on after expansion to be extruded with structure, and anchor is provided by frictional force
Effect is drawn, and the resistance pulling force effect that frictional force is provided is difficult to ensure that.
The content of the invention
The technical problems to be solved by the invention are：A kind of energy preferably build-in is provided in the intumescent anchor rod device of rock.
The present invention solves its technical problem and uses following technical scheme：
The intumescent anchor rod device that the present invention is provided, it is provided with intumescent overcoat, nut and tension anchor pole, wherein：Expansion
Type overcoat two ends are provided with perforate, make tension anchor pole that intumescent overcoat is fixed together with tension anchor pole by nut after.
In the set body outside of intumescent overcoat provided with the sharp hook in opposite direction of front end therewith, for build-in rock, work as anchor
Device can be made to move laterally during bar stress, can made in sharp hook insertion ground, so as to play the effect of anchor rod device.
Described intumescent overcoat uses fence type structure, and this is outer while be enclosed on guarantee longitudinal strength, reduces transverse direction
Rigidity so that can be easier to expand after force, only expand, the outer sharp hook put could be preferably chimeric with rock mass, plus
Strong anchoring effect.
The sharp hook of described intumescent overcoat is barb, and barb is arranged as ring-type.
Described barb, it is shaped as horn shape, and its angle is 30-45 °.
Described intumescent overcoat, its interior diameter is identical with tension bolt diameter.
Provided with a pair of nuts on tension anchor pole, nut is Anti-slip nut, positioned at the end of tension anchor pole, is applied by nut
Reinforcing makes intumescent overcoat distending, to increase and ensure the expansion effect of intumescent overcoat.
Described tension anchor pole, it is by nut and intumescent overcoat one entirety of formation, for bearing to anchor pulling force；Its
Front end is cone, and conical rear is the round platform of cylinder shape belt barb, for build-in rock；Its rear end is provided with supporting with nut
Screw thread.
Described tension anchor pole, is made up of round platform and pull bar, and round platform and pull bar are an entirety, wherein：Back end of tie rod is set
There is the barb being provided with the screw thread supporting with nut, the cylinder of round platform for build-in rock stratum, barb is shaped as horn shape, its angle
For 30-45 °
The present invention has the advantages that following main compared with prior art：
1. not only allowing for the strength problem of anchor rod device, and structure and the build-in effect of rock are considered, pass through reality
Heart pull bar provides tensile strength, makes structure and rock mass build-in by the barb put outside pull bar and intumescent, and will be arranged outside
Fence type is set to, is easy to expansion during stress, the overcoat after expansion strengthens the build-in effect with rock mass.
2. pull bar and intumescent overcoat are fixed as into an entirety by nut, and exerted a force by nut, make rail shape
Overcoat is expanded, and by barb and the rock mass build-in put outside, to ensure the stability of structure, nut is set to a pair.
3. intumescent overcoat uses fence type structure, compared with traditional cylindric cuff, this fence type structure can be with
Make to be more easy to distending during intumescent overcoat stress, preferably play its function.
4. sharp hook (barb) is set with tie rod end and intumescent overcoat set, due to barb direction and pull bar direction phase
Instead, so, when installing housing sleeve body, barb does not interfere with construction, and in stress, barb but can be preferably chimeric with rock mass, increases
Plus anchor force.
