Abstract
The utility model provides a kind of expansible grouted anchor bar, including expanding block, expander, anchor plate, circular shim, nut, stop grouting plug and slip casting pad, is related to the technical field of grouted anchor bar, and its main body is grouted anchor bar, it is characterised in that：An expansion gear, including expanding block and expander are placed in the afterbody of described grouted anchor bar, the described grouted anchor bar body of rod is divided into two steel discs, and described grouted anchor bar head connection sets nut.The beneficial effects of the utility model：The utility model is simple in construction, firmly, can go deep into any corner of hole wall, prevents the expansion of destruction area rock stratum, has saved the use of steel, reduced cost.
Description
Technical field
The utility model is related to a kind of technical field of grouted anchor bar.
Background technology
In engineering technology, mine, side slope, tunnel, dam body and mine, bolt support technology is often used.Anchor pole
Support technology refers to drill into good ground in natural stratum, squeezes into anchor pole, then the cement injection mortar in hole, so that
Limitation Rock And Soil departs from substance and increases the technology of the cohesiveness of Rock And Soil.The main tensile capacity using anchor pole, maintains soil
The side slope of body or rock mass（Or ground）It is stable.But existing anchor pole stationarity is not strong, and the materials of fixing anchor bar（Steel）Amount compares
Greatly, drawing-resistant function is not obvious.
The content of the invention
Technical problem to be solved in the utility model is to overcome prior art defect fixed reliable there is provided one kind, saved
Save steel and improve a kind of expansible grouted anchor bar of longitudinal drawing-resistant function.
Technical problem to be solved in the utility model is realized using following technical scheme：A kind of expansible slip casting anchor
Bar.Its main body is grouted anchor bar, it is characterised in that：An expansion gear is placed in the afterbody of described grouted anchor bar, including it is swollen
Expansion block and expander, the described grouted anchor bar body of rod are divided into two steel discs, and described grouted anchor bar head connection sets nut.
When the utility model is installed, embedded hole is smaller slightly larger than expansion gear diameter, it is easy to punch, while saving anchor pole
Material；When two pieces of steel discs of anchor rod body enter embedded hole, expanding block and expander friction, expanding block are close to pre-buried hole wall and become
Shape, so as to improve the weight bearing power of anchor pole.
The beneficial effects of the utility model are：The utility model was both simple in construction as a kind of expansible grouted anchor bar,
It is again solid and reliable, steel are mainly saved, cost is reduced.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the utility model steel plate putting position schematic diagram.
Marginal data：1- rock mass；2- embedded holes；3- expanding blocks；4- expanders；5- body of rod steel discs；6- circular shims；7- is noted
Starch pad；8- nuts；9- stop grouting plugs；10- injected holes；Number steel plate of 11-；No. bis- steel plates of 12-.
Embodiment
In order that technological means, creation characteristic, reached purpose and effect that the utility model is realized are easy to understand, under
Face combines and is specifically illustrating, and the utility model is expanded on further.
As shown in figure 1, the utility model includes a kind of expansible grouted anchor bar, including expanding block 3, expander 4, the body of rod
Steel disc 5, circular gasket 6, slip casting pad 7, nut 8 and stop grouting plug 9.
One embedded hole 2 for being slightly larger than expansion gear is first set when the utility model is installed in rock mass 1, by expanding block 3
Embedded hole 2 is together put into together with expander 4, the body of rod steel disc 5 of anchor pole is then squeezed into embedded hole 2, body of rod steel disc putting position
It must be the relative position of a steel disc 11 and No. two steel discs, be allowed to deform by extrusion expansion block 3 and expander 4, be close to pre-
The wall of buried via hole 2, so as to reach certain anchorage effect.By the slip casting of injected hole 10, so that whole embedded hole 2 fills up cement mortar,
Tightening nut 8 and stop grouting plug 10 are so that whole expansible grouted anchor bar is integrally formed, after cement slurry sets to be implanted,
Structural bearing capacity of the present utility model will be greatly improved.
Claims (2)
1. a kind of expansible grouted anchor bar, including expanding block, expander, body of rod steel disc, circular shim, nut, stop grouting plug with
