Description
Technical field
The utility model relates to a kind of pre-stress construction facility, particularly a kind of unbonded tendon ring anchor sealing system.
Background technology
Unbonded tendon ring anchor system requires that unbonded tendon and clamping anchorage unit are hermetically sealed, the first is in order to ensure the high-stress state anticorrosion needs of lower prestress muscle, and long-term anchoring property is reliable, it two is to prevent grease from spilling, cause environmental pollution, hydro project particularly can directly affect water quality. at present, the sealing means of unbonded tendon ring anchor system is such as Figure 14, exposed for every root unbonded tendon is sealed by the method utilizing end face rubber cushion blocks to add seal cartridge, owing to folder sheet exceeds anchor slab end face, often pays folder sheet gap bigger, the grease of unbonded tendon is easily overflow to anchor slab end face by folder sheet gap, although there being rubber pad to seal as transition, but the compression of monoblock rubber pad is limited, cannot ensure that grease is non-leakage by effective sealing, reliability is not high, and application project has occurred oil seepage phenomena, patent announcement number is that CN201033913Y " unbonded tendon ring anchor anchor head corrosion-resisting device " discloses a kind of integral seal device, this device utilizes the cavity that second box upper adds two end cover plate or left and right half box is closed, anticorrosion object to reach of infusion epoxy resin or urethane in cavity, it is excessive that the protective guard that this device drawback is in this patent accounts for notch space, need to pour into more anticorrosion material, anticorrosion material intensity is low, much smaller than concrete strength, affect notch district bulk strength, and the anticorrosion material poured into can be fixing with work clip sheet bonding, affect anchoring property.
Summary of the invention
The purpose of this utility model is to provide a kind of unbonded tendon ring anchor sealing system, is sealed separately by every root unbonded tendon, can effectively carry out anticorrosion to each anchoring unit place presstressed reinforcing steel; Do not affect adjacent unbonded tendon preservative effect; Folder sheet can be provided long-term snap-in force by sealing system, avoids folder sheet to loosen.
The technical scheme solved the problem is: a kind of unbonded tendon ring anchor sealing system, comprise the anchor slab for anchoring unbonded tendon, folder sheet, the two ends end to end of unbonded tendon are anchored at A face and the B face of anchor slab respectively, it is characterized in that: this unbonded tendon ring anchor sealing system also comprises transition conduit, sealed joint pipe, bolt, pressing plate, sealing-ring; Step hole is had respectively at the big end of anchor slab taper hole and straight hole end;
In the mounted state, securing ring, transition conduit, pressing plate, the sealed joint pipe that sealing-ring is housed are enclosed within unbonded tendon successively, unbonded tendon is worn in anchor slab respective aperture, folder sheet is after stretch-draw terminates, under end face sinks to anchor slab end face, pressing plate is by bolt press seal pipe connecting, and sealing-ring hole heavy with anchor slab coordinates, and folder sheet end loads seal cartridge and forms folder sheet end radial seal; The little end of sealed joint pipe is taper structure, with transition conduit swelling fitted seal; Transition conduit is entangled shelling the unbonded tendon except PE pipe because stretching construction needs, overlap with the PE pipe of unbonded tendon, transition conduit is locked by securing ring, being coated with anticorrosion paint special on unbonded tendon surface or be filled with anticorrosion grease between unbonded tendon and transition conduit, sealed joint pipe or seal cartridge, every root unbonded tendon forms unbonded tendon and the complete independent sealed structure of clamping anchorage unit.
Its equivalent technical scheme is: folder sheet end realizes the sealing to folder sheet end unbonded tendon with sealing cover, transition conduit and sealed joint pipe replacement seal cover.
The further technical scheme of described unbonded tendon ring anchor sealing system is: at seal cartridge or there is a spring washer between sealed joint pipe and pressing plate, after pressing plate is fixed, pressing plate provides snap-in force can to seal cartridge or sealed joint pipe, and is held out against by folder sheet by seal cartridge or sealed joint pipe.
The further technical scheme of described unbonded tendon ring anchor sealing system or: on the taper hole of anchor slab two ends, have 2 steps, seal cartridge or sealed joint pipe there is a step respectively, seal cartridge or sealed joint pipe coordinate with the step on anchor slab taper hole after loading onto sealing-ring, it is achieved end face and radial double seal.
The further technical scheme of described unbonded tendon ring anchor sealing system or: replace securing ring by transition conduit lock sealing with thermal shrinkable sleeve.
