Abstract
The utility model relates to an anticorrosive device with prestressing steel strand anchor head, in particular to an anticorrosive device with unbonding reinforcement ring-shaped anchor head, which comprises a protective cover with injection holes and anticorrosive materials injected into the protective cover. The protective cover is a totally enclosed hollow cavity formed by an upper half box cover and a lower half box cover which are separate and a left end cover and a right end cover, or a left half box body and a right half box body which are separate and connecting pieces. A through hole without bonding reinforcement is arranged on the left and right end cover plates or on the bottom of the left half box body and the right half box body. The corrosive materials injected into the protective cover are anticorrosive grease or solidified polyurethane or epoxy resin with functions of sealing and anticorrosion. Compared with prior art, the utility model has the advantages of simpler structure, more convenient construction, and reliable, whole, long-time, effective anticorrosion on ring-shaped anchorage with prestressing reinforcement on both sides of anchor slab.
Description
Technical field:
The utility model relates to a kind of prestress wire anchor head anti-corrosive apparatus, particularly a kind of unbonded tendon ring anchor anchor head anti-corrosive apparatus.
Background technology:
In the prestressed reinforced concrete structure engineering, bear all on the anchoring tool because unbonded tendon is prestressed, so, very high to the requirement for anticorrosion of anchoring tool and steel strand.For this reason, the applicant has applied for utility model patent " " the unbonded tendon anchor head anti-corrosive apparatus " patent No.: ZL982099207 " in 98 years, this patent structure is simple, and can be reliably to prestressing force unbonded tendon anchor head partly wholely carry out for a long time, effectively anticorrosion, but in the practice, the applicant finds: this anchor head anti-corrosive apparatus only paid attention to anchor head partly wholely carry out for a long time, effectively anticorrosion, for the two sides all anchoring ring-like ground tackle anticorrosion desirable not enough of presstressed reinforcing steel arranged.
The utility model content:
The technical problems to be solved in the utility model is: the applicant's utility model patent " " the unbonded tendon anchor head anti-corrosive apparatus " patent No.: ZL982099207 " is further improved, provide a kind of simple in structure, and can be reliably all have anchoring to have that the ring-like ground tackle of presstressed reinforcing steel is whole carries out long-time, effective corrosion-resistant unbonded tendon ring anchor anchor head anti-corrosive apparatus to two aspects.
The technical scheme that solves its above-mentioned technical problem is: a kind of unbonded tendon ring anchor anchor head anti-corrosive apparatus; comprise the protective cover that has injection orifice and inject the interior preservative substance of protective cover; the totally enclosed hollow cavity that described protective cover is made up of a left side half box body, right half box body and the connector thereof of first lid, second box and left and right sides end casing or the separation that separate, on the end casing of the left and right sides or the bottom of left half box body, right half box body has the through hole of wearing unbonded tendon.
Further technical scheme of the present utility model is: the preservative substance in the described injection protective cover is epoxy resin or the polyurethanes anti-corrosion material that has the sealing corrosion effect after solidifying.
Owing to adopt said structure, the unbonded tendon ring anchor anchor head anti-corrosive apparatus of the utility model is simpler than existing unbonded tendon anchor head anti-corrosive apparatus structure, more convenient during construction, and can be reliably to the anchor slab two sides all anchoring have the ring-like ground tackle of presstressed reinforcing steel wholely carry out for a long time, effectively anticorrosion.
Below, the technical characterictic to the unbonded tendon ring anchor anchor head anti-corrosive apparatus of the utility model is further described in conjunction with the accompanying drawings and embodiments.
