Abstract
A kind of fluking type grouted rock bolt of the present invention, including anchor bar body, the circumferencial direction distribution of the front end of anchor bar body along anchor bar body are provided with multiple reinforcing bar barbs, and the middle part of anchor bar body offers injected hole along its length.The setting of reinforcing bar barb, strengthens the stationarity between anchor pole and Rock And Soil, effectively avoids anchor pole from sliding in and out, and the contact area between spiral floor increase anchor pole and Rock And Soil further avoids anchor pole from sliding in and out, and improves the stability of anchor pole.The invention belongs to mooring rod technique field.
Description
Technical field
The present invention relates to mooring rod technique field, more particularly to a kind of fluking type grouted rock bolt.
Background technology
Prestressed anchor refers to set gos deep into the reinforcing bar in steady soil (or anchor cable) and slip casting in hole with the interior, end that drills
The tension body of rod of body composition, the other end of reinforcing bar (or anchor cable) is fixed and Rock And Soil or retaining structure surface, and anchor pole is applied
Certain pretension, using the screen resilience of anchor pole compress can slidable Rock And Soil or retaining structure, it is anti-on sliding surface to increase
Intensity is cut, so as to reach the purpose for improving Rock And Soil or retaining structure stability.Hole diameter is small needed for Anchor Rod Retaining Wall, without
Big machinery, light structure, reliability is high.
The present inventor has found that existing tubular type prestressed anchor, stability is poor in use, using going out journey
Middle anchor pole easily slides, come off, and reduces safety coefficient.
Then, inventor in view of this, adhere to the relevant industries for many years it is abundant design and develop and actual fabrication experience,
Improvement is studied there is provided a kind of new fluking type grouted rock bolt for existing structure and missing, is had more more to reach
Plus the purpose of practical value.
The content of the invention
It is an object of the invention to provide a kind of fluking type grouted rock bolt, to solve the stabilization proposed in above-mentioned background technology
Poor-performing, is easily sliding, is coming off using going out anchor pole in journey, the problem of reduction safety coefficient.
The purpose of the present invention and effect, are reached by technological means in detail below：A kind of fluking type grouted rock bolt, the filling
Starching anchor pole includes anchor bar body, and the circumferencial direction distribution of the front end of anchor bar body along anchor bar body is provided with multiple reinforcing bar barbs, anchor bar body
Middle part offer injected hole along its length.
In foregoing anchor pole, the circumferencial direction distribution of the front end of anchor bar body along anchor bar body is provided with four reinforcing bar barbs, reinforcing bar
Barb is " V " font overhead structure that one end is fixed on anchor pole body sidewall, facilitates anchor bar body to bury, and more firm；
In foregoing anchor pole, spiral floor is fixedly installed on the outer wall of anchor bar body, spiral floor is prolonged by the tail end of anchor bar body
The front end of anchor bar body is extended, is easy to anchor bar body to bury, and auxiliary can be carried out using spiral floor and is poured.
With existing structure in comparison, the invention has the advantages that：
1. the setting of reinforcing bar barb of the present invention, is conducive to strengthening the stationarity between anchor pole and Rock And Soil by reinforcing bar barb
Can, it can effectively avoid anchor pole to slide in and out, come off.
2. the setting of spiral floor of the present invention, is conducive to increasing the contact area between anchor pole and Rock And Soil, while can carry
The intensity of high anchor pole.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention；
Fig. 2 is Fig. 1 right view.
Embodiment
Below, embodiments of the invention are will be explained in, the example is shown in the accompanying drawings and the description below.Although will combine
The exemplary embodiment description present invention, it is to be understood that the description is not really wanted to limit the invention to the exemplary implementation
Example.On the contrary, the present invention will not only cover the exemplary embodiment, but also cover various replacements, change, it is equivalent and
Other embodiment, it can be included in the spirit and scope of the present invention that appended claims are limited.
Such as accompanying drawing 1 and accompanying drawing 2, a kind of fluking type grouted rock bolt, it is characterised in that：Described tubular type prestressed grouting anchor pole
Including anchor bar body 1, the circumferencial direction distribution of the front end of anchor bar body 1 along anchor bar body 1 is provided with four reinforcing bar barbs 2, reinforcing bar barb 2
" V " the font overhead structure being fixed on for one end on the side wall of anchor bar body 1, facilitates anchor bar body to bury, is conducive to by reinforcing bar barb 2
Strengthen the fixed performance between anchor pole and Rock And Soil, can effectively avoid anchor bar body 1 from sliding in and out, come off, the outer wall of anchor bar body 1
On be fixedly installed spiral floor 3, spiral floor 3 is extended to the front end of anchor bar body 1 by the tail end of anchor bar body 1, is easy to anchor bar body
Bury, and auxiliary can be carried out using spiral floor 3 and pour, the middle part of anchor bar body 1 offers injected hole 4 along its length.
The preferred embodiment of fluking type grouted rock bolt as described above, wherein, the diameter of the center section of anchor bar body 1 is less than
The diameter at the two ends of anchor bar body 1, is easy to spiral floor 3 being welded on the middle part of anchor bar body 1, while screw rod floor 3 can be avoided
The outer wall that is higher by anchor bar body 1 is more, laborious when installing；
It should be noted that the standardized element that the present invention is used can commercially, shaped piece is according to explanation
Book and accompanying drawing record can carry out customized, and the specific connected mode of each part is using spiral shell ripe in the prior art
The conventional meanses such as bolt, rivet, welding, machinery, part are using in the prior art, and conventional model, inventor is no longer detailed herein
State.
In summary, although the present invention is described in detail with reference to the foregoing embodiments, for the technology of this area
For personnel, it can still modify to the technical scheme described in foregoing embodiments, or to which part technology
Feature carries out equivalent substitution, within the spirit and principles of the invention, any modification, equivalent substitution and improvements made etc.,
It should be included within protection scope of the present invention.
