Abstract
The utility model provides a kind of foot bridge CFRP drag-line bonding extrusion pressing type anchor structure, includes capping, nut, sleeve, holds stifled, CFRP reinforcing bar, containment member；The sleeve is cylindrical structure, this sleeve and cover rim by solder bond, and it is seamless filled in the gap between the two junction have containment member, which is formed by adhesive glue processing；The nut is fixed on cartridges sides in the form being embedded in；The end get lodged in strong pressure effect under it is seamless fill between sleeve inner and CFRP reinforcing bar, fitted closely with sleeve inner and CFRP reinforcing bar；The CFRP reinforcing bar under the action of strong pulling force straight run through sleeve, around dense packing effect have containment member；The containment member is closely poured among sleeve under the action of strong pressure.
Description
Technical field
The utility model relates to inhaul cable anchorage structure, especially a kind of foot bridge CFRP drag-line bonding extrusion pressing type anchoring knot
Structure.
Background technique
With the continuous growth of span of bridge, traditional steel cable is due to from great, cable sag effect is obvious, load-carrying efficiency is low etc.
Disadvantage limits the promotion of super-span span of bridge.While the fatigue strength of traditional steel cable is not high, poor corrosion resistance, steel
The service life of drag-line greatly shortens under in fatigue and the wine cooperation of corrosion, affects the long service performance of steel cable.
Utility model content
The purpose of this utility model is that it is in view of the drawbacks of the prior art and insufficient, a kind of CFRP drag-line bonding extruding is provided
Type anchor structure, the structure can not only effectively mitigate the self weight of drag-line, increase the across footpath of super-span bridge, and can also be effective
Raising drag-line long service performance, for improve super-span bridge short-term, long-term behaviour provide an effective approach.
A kind of foot bridge CFRP drag-line bonding extruding that in order to achieve the above purposes, the technical solution adopted by the utility model is:
Type anchor structure includes capping, nut, sleeve, holds stifled, CFRP reinforcing bar, containment member；The sleeve is cylindrical structure,
This sleeve and cover rim by solder bond, and it is seamless filled in the gap between the two junction have containment member, this is close
Envelope component is formed by adhesive glue processing；The nut is fixed on cartridges sides in the form being embedded in；The end, which is got lodged in, suppresses masterpiece
It is seamless under to fill between sleeve inner and CFRP reinforcing bar, it is fitted closely with sleeve inner and CFRP reinforcing bar；The CFRP steel
Muscle under the action of strong pulling force straight run through sleeve, around dense packing effect have containment member；The containment member is in strong pressure
Under the action of, closely it is poured among sleeve.
The beneficial effects of the utility model are: the structure can not only effectively mitigate the self weight of drag-line, increase super large bridge
The across footpath of beam, and the long service performance of drag-line can also be effectively improved, for short-term, the long-term behaviour for improving super-span bridge
Provide an effective approach.
Detailed description of the invention
Attached drawing described herein is to be used to provide a further understanding of the present invention, and constitutes one of the application
Point, but and restriction of the composition to the utility model.
Fig. 1 is the structural schematic diagram of the guy system.
Wherein: 1- capping, 2- nut, 3- sleeve, the end 4- is blocked up, 5-CFRP reinforcing bar, 6- bond colloid.
Specific embodiment
In conjunction with attached drawing, the utility model is described in further detail.
As shown, a kind of foot bridge CFRP drag-line bonds extrusion pressing type anchor structure, it include 1- capping, 2- nut, 3-
Sleeve, the end 4- be stifled, 5-CFRP reinforcing bar, 6- containment member；The 3- sleeve is cylindrical structure, this 3- sleeve and 1- cover rim
By solder bond, and it is seamless filled in the gap between the two junction have 6- containment member, the 6- containment member is by bonding
Glue processing is formed；The 2- nut is fixed on 3- cartridges sides in the form being embedded in；The end 4- gets lodged in strong pressure and acts on lower nothing
Seam is filled between 3- sleeve inner and 5-CFRP reinforcing bar, is fitted closely with 3- sleeve inner and 5-CFRP reinforcing bar；The 5-
CFRP reinforcing bar under the action of strong pulling force straight run through 3- sleeve, around dense packing effect have 6- containment member；The 6- sealing
Component is closely poured among 3- sleeve under the action of strong pressure.
The technology contents and technical characteristic of the utility model have revealed that as above those skilled in the art still may base
In the utility model teaching and make the replacement and modification without departing substantially from the utility model in essence, therefore, the utility model protection
Range is not limited to the revealed content of embodiment, also includes various replacements and modification without departing substantially from the utility model in essence.
