Description
Technical field
The present invention relates to mooring rod technique field, more particularly to a kind of prestressed grouting anchor pole with butterfly backing plate.
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,
Study and is improved there is provided a kind of prestressed grouting anchor pole with butterfly backing plate for existing structure and missing, to up to
To the purpose with more more practical value.
The content of the invention
It is an object of the invention to provide a kind of prestressed grouting anchor pole with butterfly backing plate, to solve above-mentioned background skill
The stability proposed in art is poor, is easily sliding, comes 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 prestressing force with butterfly backing plate
Grouted rock bolt, the grouted rock bolt 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 barb, the middle part of anchor bar body offers injected hole along its length, and the tail end of anchor bar body is vertically and fixedly provided with butterfly backing plate,
Offered in the middle part of butterfly backing plate and multiple pin holes are along the circumferential direction offered on connecting hole, butterfly backing plate, set in pin hole
There is pin, one end of pin is to be provided with the detachable head of a nail on fluking type structure, the other end.
In foregoing prestressed grouting anchor pole, offered on butterfly backing plate in eight pin holes, four one group, every group of pin holes
The centre distance of four pin holes to butterfly backing plates is identical, and circumferencial direction of four pin holes along butterfly backing plate is uniform in every group
Distribution is set；
In foregoing prestressed grouting anchor pole, internal thread is provided with the inside of the connecting hole in the middle part of butterfly backing plate, with anchor pole tail
End external screw thread matches.
In foregoing prestressed grouting anchor pole, the circumferencial direction distribution of the front end of anchor bar body along anchor bar body is provided with four reinforcing bars
Barb, 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
Firmly.
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 butterfly backing plate of the present invention with barb-shaped pin, is conducive to strengthening between butterfly backing plate and Rock And Soil
Stability, further avoid anchor pole from sliding in and out, improve anchor pole stability.
Brief description of the drawings
