Description
Technical field
This utility model relates to a kind of sealing device, belongs to highway bridge construction field.
Background technology
Tradition cable saddle saddle two endplate and sealing plate space employing anticorrosion oils and fats be filled with.Saddle end plate, sealing
Pad and transition conduit are with bolts, and isolation contacts with tower external environment, prevent the extreme meteorological conditions such as sleet for the shadow of saddle
Ring.But this mode is difficult to avoid that steam passes through HDPE outer sheath tube and penetrates into the end of saddle, and the anticorrosion oils and fats of liquid easily enters
Enter the droplet-shaped duct in saddle, reduce friction, reduce the chucking power in duct.
Utility model content
For overcoming above-mentioned deficiency, this utility model purpose is to provide a kind of sealing device.Ensure low-pylon cable-stayed bridge prestressing force
The construction quality of guy system, when safeguarding bridge construction and operation, the safety and stability of prestress system, extends the use longevity of drag-line
Life.
Scheme of the present utility model is as follows: a kind of sealing device, including pressing plate, rubber slab, rebound and bolt, institute
Pressing plate, rubber slab and the rebound close fit successively stated；
Described bolt one end is fixed on pressing plate, and the other end sequentially passes through rubber slab and rebound；Described mistake
Arranging the through hole that is correspondingly arranged of sub-wire hole, rubber slab and pressing plate on cab apron, through hole connects with sub-wire hole；
Described rebound top arranges steam vent, and bottom arranges hole for injecting glue；Described rubber slab and pressing plate are the most axially
It is correspondingly arranged the through hole connected with steam vent, hole for injecting glue.
Further, described inlet side, sub-wire hole and go out end and be arranged to step-like.
Further, arranging sealing ring between described sub-wire hole and rubber slab through hole, described sealing ring is arranged on sub-wire
Hole goes out on the stepped hole of end.
Further, described bolt is divided into long bolt and short bolt.
This utility model adds pressure strip outside the water-drop-shaped dividing plate of saddle two ends, can prevent inserts from entering droplet-shaped hole
Road；At cable saddle end bulkheads and turn between sealing device filling colloidal resin, inserts uses colloidal resin, with tradition anticorrosion
The mode that grease seal processes is compared, and uses colloidal resin encapsulation process to there is significant performance advantage: colloidal resin has one
Fixed stickiness, it will not be because the steel strand wires that the impact of traffic load or wind battle array effect cause shake along steel strand wires PE outer jacket
Surface is overflowed.This utility model realizes droplet-shaped saddle multi-layer anticorrosion, and to completely cut off the outer steam of tower, steel strand wires are invaded by corrosive medium
Erosion.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model sealing device.
Detailed description of the invention
Below in conjunction with embodiment, this utility model is described further.
A kind of sealing device, including pressing plate 1, rubber slab 2, rebound 3 and bolt 4, bolt 4 one end is fixed
On pressing plate 1, the other end sequentially passes through rubber slab 2 and rebound 3, by pressing plate, rubber slab and rebound successively close fit；Cross
Arranging sub-wire hole 5, rubber slab 2 and pressing plate 1 on cab apron and be axially correspondingly arranged through hole, through hole connects with sub-wire hole；Rebound 3 top
Arranging steam vent 6, bottom arranges hole for injecting glue 7；Rubber slab is the most axially correspondingly arranged with pressing plate and connects with steam vent, hole for injecting glue
Through hole.
Inlet side, this utility model sub-wire hole and go out end and be arranged to step-like.Between sub-wire hole and rubber slab through hole, sealing is set
Circle, sealing ring is arranged on sub-wire hole and goes out on the stepped hole of end.Bolt is divided into long bolt and short bolt.Long location
Bolt is connected with the fixing of external device (ED) for this device, and short bolt includes pressing plate, rubber slab and rebound for this device
Between fixing.
This utility model turns to the rubber mat plate in sealing device to have good extension property.During screwed in place bolt,
Rubber mat plate compression, it is possible to the space sealed between transfer duct and steel strand wires and saddle inwall are turned to sealing
The space closure of device is tamped, thus prevents colloidal resin from oozing out from space.Sealing device is turned to use high intensity location spiral shell
Bolt, it is possible to meet the requirement to bolt strength of the factor such as traffic load, dead load.
Pressure strip of the present utility model and turn in sealing device rubber slab to select neoprene, its tensile strength 10-
30MPa.Elongation at break 250%, tearing strength 20-80KN, mooney viscosity 40-120ML, damped coefficient 0.15-0.30, remaining
Index all meets the requirement of GB/T14647-2008 " neoprene divinyl rubber CR121, CR122 ".
The colloidal resin that this utility model uses is FASTEN1000A material, is widely used in bridge stay cable prestressing force body
Being the preserving and sealing operation of anchoring section, its durability and reliability have obtained the inspection of many projects under construction.
This utility model adds pressure strip outside the water-drop-shaped dividing plate of saddle two ends, can prevent inserts from entering droplet-shaped hole
Road；
At cable saddle end bulkheads and turn between sealing device filling colloidal resin, inserts uses colloidal resin, with biography
The mode of system anticorrosion oils and fats encapsulation process is compared, and uses colloidal resin encapsulation process to there is significant performance advantage: colloidal resin
Tool is a bit sticky, and it will not be because the steel strand wires that the impact of traffic load or wind battle array effect cause shake along steel strand wires PE
Outer jacket surface is overflowed.This utility model realizes droplet-shaped saddle multi-layer anticorrosion, and to completely cut off the outer steam of tower, steel is twisted by corrosive medium
The erosion of line.
Although above detailed description of the invention of the present utility model to be given detailed description and explanation, but it should be noted that
It is that we can carry out various equivalence according to conception of the present utility model to above-mentioned embodiment and change and amendment, and it is produced
Function still without departing from description contained spiritual time, all should be within protection domain of the present utility model.
