Description
Technical field
The present invention relates to machinery field, be specifically related to a kind of anchor rod device and utilize anchor rod device anchor
Gu the method reinforcing cross section.
Background technology
The reinforcement method of enlarging section that increasing section method for strengthening is the most described.It is by using and former component
Identical or more preferable material, casting concrete be equipped with enough reinforcing bars in order to increase outside former component
The sectional dimension of component reaches to improve element bearing capacity, rigidity and the purpose of stability.Increase at present
Heavy in section method for strengthening is equally faced with the old and new's interface peel and concrete cover stripping with other method for strengthening
From problem.
By arranging a number of anchor rod anchored generation that can be effectively prevented interface peel, and
The generation that concrete cover is peeled off can also be effectively prevented when anchor pole implantation depth is bigger.Utilize anchor
The feature that bar anchoring has the most efficiently, stock utilization is high.But common anchor rod device is arranged not
Can effectively regulate implantation depth, cause anchor pole to implant height height, be usually unable to limit concrete
The generation that protective layer is peeled off.Common bolt anchor reaches to improve by anchor pole applies pretightning force
The purpose of interface peel intensity, but limited anchor pole is implanted height pretightning force and can not effectively be applied.Cause
This anchor rod anchored device is to improving the effect of interface peel intensity also and non-ideal.
The concrete members needed reinforcement generally has suffered partial injury the most, therefore there is bigger coagulation
Soil cracking stitches.Use increasing section method for strengthening bright, before Slit bottom and back-up coat usual all exist bigger
Space.The existence in this space reduces interface binding intensity, it is therefore necessary to enter distress in concrete
Row is filled up.Fill up distress in concrete at present to be injected by implant holes by epoxy resin mainly by high pressure
In concrete, but to use operational procedure in increasing section method for strengthening the most loaded down with trivial details for this method, and
And fill-before-fire concrete easily causes the rinforcement bar position the fullest existence of concrete one after resin by injection slurry
Fixed gap thus reduce the adhesion strength at the old and new interface.

The present invention, by installing location nut on anchor pole, can efficiently control the implantation depth of anchor pole,
Treat that concrete cover stripping damage phenomenon occurs in strenthening member it is thus possible to be prevented effectively from.Actually anchor pole
Be equivalent to a kind of injection device, can be effective to treating injection ring epoxy resins in strenthening member by this utensil
Make it be full of in concrete members crack to be reinforced, and make to be impregnated with resin around reinforced steel so that its
Occur without gap with treating strenthening member to be completely embedded, the bonding further increasing the old and new interface is strong
Degree.
By clamp nut and pressing plate, back-up coat is applied pretightning force, make back-up coat and treat strenthening member even
Connect closely it is thus possible to be effectively prevented from that back-up coat occurs and treat that interface peel occurs in strenthening member
Breakoff phenomenon.
Compared with prior art, present invention have the advantage that
1, the present invention effectively fills up, by anchor pole, the concrete damage crack treating that strenthening member occurs, makes
The old and new's interfacial adhesion is the tightst, it is thus possible to more effectively improve the adhesion strength at the old and new interface；
2, the present invention controls the implantation depth of anchor pole by arranging location nut, thus effectively limits
The generation that concrete cover is peeled off, and anchor pole highly controllable thus there is general versatility；
3, the present invention applies higher pretightning force by clamp nut and pressing plate to back-up coat, thus energy
More effectively improve back-up coat and the interface binding intensity treated between strenthening member, prevent boundary further
The possibility that face stripping damage occurs.
Assembly of the invention is simple, makes simple efficient, utilization rate height, thus has good economy
Property and the suitability.
