Abstract
The utility model relates to a changeable suspension bridge anchored prestressed anchoring system which relates to a prestressed anchoring system, comprising an upper anchoring part, a span wire coupling part and a lower anchoring part. A boot cap, a locking device, an anchor device, a connector flat plate, a connecting cylinder, an anchoring bottom plate, a spiral bar, and a built-in steel pipe which are consecutive connected form the upper anchor. The boot cap, the locking device, the anchor device, the anchoring bottom plate, the spiral bar, and the built-in steel pipe which are consecutive connected form the lower anchor. The system is characterized in that: the built-in steel pipe (12) connects to the upper and lower anchor and forms a fully sealed cavity in which anti-corrosive oil or anti-corrosive oil and fat (13) are filled, and a changeable suspension bridge anchored prestressed anchoring system is formed by the non-adhered steel strands passing through the sealed cavity. The anchor system which has good anti-corrosive property is favorable for checking the rope force and can carry out stress adjustment or change prestressed ribs.
Description
Technical field
The utility model relates to a kind of prestress anchorage system, particularly a kind of interchangeable suspension bridge anchorage prestress anchorage system.
Background technology
The anchorage prestress anchorage system that adopts has been generally the non-exchange form of bonding at present, the protected mode of the anticorrosion general employing pressure injection mortar of presstressed reinforcing steel, the i.e. cement mortar that perfusion can be solidified in prestress pipe, whole anchorage prestress anchorage system is consolidated; This kind mode has following shortcoming:
1, the anchorage prestress anchorage system in later stage operation process since presstressed reinforcing steel and concrete binding together presstressed reinforcing steel can't check, detect Suo Li again, can not adjust or change;
2, concrete is good far away from the performance of anticorrosion grease to the antiseptic property of presstressed reinforcing steel; And adopt that concrete mortar is anticorrosion to exist a lot of hidden danger when construction, as slurry bleeding, grouting leakiness or the like, to the construction requirement height;
In case 3, bonded prestressed tendon corrosion failure is catastrophic to main push-towing rope then, can't remedy.
For addressing the above problem, (predecessor cried the applicant: once proposed " prestressing force anchorage " (patent No.: 97219877.6) utility application Sino-foreign joint venture Liuzhou, Liuzhou Ou Weimu building machinery Co., Ltd) in 97 years, disclose a kind of presstressed reinforcing steel and adopted unbonded tendon, sealing mat is contained in the exposed end up and down of unbonded tendon respectively, make sealing mat form annular seal space between the anchor plate, carry out anticorrosion effectively by antirust oil or the anti-corrosive grease of filling with in the annular seal space to the unbonded tendon exposed part that passes in the annular seal space, but use discovery through reality, the structure that this kind is partially sealed, construction is difficulty relatively, particularly changes Suo Yihou and does not guarantee sealing performance.
The utility model content
The technical problems to be solved in the utility model is: the non-exchange presstressed reinforcing steel that existing bonded prestress anchorage exists and the problems referred to above that adopt the concrete mortar sealing to exist, and the construction that the prestressing without bondn anchorage of partially sealed structure exists is relatively more difficult, particularly change Suo Yihou and do not guarantee the problem of sealing performance, a kind of hermetic interchangeable suspension bridge anchorage prestress anchorage system is provided, this anchoring system can increase substantially the antiseptic property of whole system, and help checking, detecting Suo Li, can carry out the stress adjustment or change presstressed reinforcing steel.
The technical scheme that solves its above-mentioned technical problem is: a kind of interchangeable suspension bridge anchorage prestress anchorage system; comprise anchorage part; the suspension cable coupling part; following anchorage part; last anchorage part is by the protective cover that links to each other successively; ground tackle; the connector flat board; connecting cylinder; anchor plate; spiral bar; embedded steel tube is formed; following anchorage part is by the protective cover that links to each other successively; ground tackle; anchor plate; spiral bar; embedded steel tube is formed; it is characterized in that: described embedded steel tube be communicated with up and down anchorage part and with hermetically sealed chamber of its formation; fill antiseptic oil in the chamber, non-bending steel cable is in the parallel sealing chamber of passing of embedded steel tube.
Because adopt said structure, the interchangeable suspension bridge anchorage prestress anchorage system of the utility model has following beneficial effect:
1, the hermetically sealed chamber of forming by connector flat board, connecting cylinder, the embedded steel tube of upper and lower anchorage part and last anchorage part, fill the antiseptic oil of good fluidity in the chamber, make whole anchorage prestress anchorage system be immersed in wherein, because the antiseptic power of anticorrosion grease is much higher than cement mortar, thereby, the antiseptic property of whole anchorage system is significantly improved;
2, adopt the unbonded prestressing tendon form to help checking, detecting Suo Li, can carry out the stress adjustment or change presstressed reinforcing steel;
3, presstressed reinforcing steel keeping parallelism in the embedded steel tube pipeline helps the transmission of power and changes presstressed reinforcing steel;
4, since adopt embedded steel tube be communicated with up and down anchorage part and with hermetically sealed chamber of its formation, need not establish sealing mat respectively at upper and lower anchorage part, its good sealing effect, and easy construction, to change presstressed reinforcing steel also more convenient in the future;
5, in the ground tackle locking device can be set up and down, improve the anchoring safety of anchorage prestress anchorage system.
