Description
Technical field
The present invention relates to a kind of suspension cable, belong to technical field of bridge engineering.
Background technology
Suspension cable is the main load-carrying member of cable stayed bridge, and its durability directly affects the safety of cable stayed bridge, economy and reliability.The durability of suspension cable mainly comprises the durability of suspension cable system, the durability at the excessive position of connection of suspension cable and tower end and suspension cable and beam-ends forms.In recent years, the durability of suspension cable system by carry out in factory at the outer hot extrude permanent seal cooling high density polyethylene (HDPE) sheath of steel tendon, in ground tackle, pour into the measures such as sealed filling material effectively ensured.
Beam-ends for suspension cable generally arranges a bucker, and this bucker one end is connected with the built-in pipe of cable stayed bridge, and one section is connected with suspension cable, and the periphery that the large small end of bucker does not wait with two diameters simultaneously coordinates.In actual installation, due to bucker and two peripheries no-float simultaneously cannot be realized, generally ensure that large end coordinates with built-in pipe periphery, small end and suspension cable periphery reserve certain gap, after installation, in the gap between bucker small end and drag-line, insert silastic sealing strip and fluid sealant.But in the practice of construction process at bridge, built-in pipe and oblique pulling cable body cannot reach desirable concentric, and suspension cable is in operation and also can vibrates due to vehicular load, and therefore silastic sealing strip and fluid sealant cannot play waterproof effect.In actual use, there is a large amount of ponding in the built-in pipe of discovery suspension cable beam-ends, cause suspension cable anchor head to be immersed in water, affect the result of use of suspension cable.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, provide and a kind ofly stopped the suspension cable beam-ends tarpaulin that moisture content enters bucker.
The object of the present invention is achieved like this:
A kind of suspension cable beam-ends tarpaulin, be characterized in: described tarpaulin comprises tarpaulin body, small end and the cable body of described tarpaulin body fit tightly, the front end of tarpaulin body small end is provided with the first groove, be provided with the second weather strip in first groove, the middle part of described tarpaulin body small end is provided with the second groove, is provided with sealing ring in the second groove, the large end of described tarpaulin body is provided with the 3rd groove, is provided with the first weather strip in the 3rd groove.
A kind of suspension cable beam-ends of the present invention tarpaulin, its first weather strip, sealing ring and the second weather strip adopt silastic material to make.
A kind of suspension cable beam-ends of the present invention tarpaulin, its tarpaulin is for breathing out furan structure and adopting stainless steel or carbon steel material to make.
Compared with prior art, the invention has the beneficial effects as follows:
A kind of suspension cable beam-ends of the present invention tarpaulin, its first weather strip, sealing ring and the second weather strip are formed and prevent moisture content from entering the three lines of defence of bucker, rely on sealing ring to produce precommpression and be out of shape the gap adapting to Inclined Cable Vibration etc. and produce, realize, with the dynamic self-adapting sealing effectiveness of oblique pulling cable body, improve the durability at the excessive position of connection of suspension cable and beam-ends.

Detailed description of the invention
See Fig. 1, the present invention relates to a kind of suspension cable beam-ends tarpaulin, bucker 2 is entered for preventing moisture content, improve the durability at the excessive position of connection of suspension cable and beam-ends, the large end of described bucker 2 is connected with the built-in pipe 11 of cable stayed bridge, and coordinates with built-in pipe 11 periphery, small end is connected with cable body 1, and coordinate with the periphery of cable body 1, there is gap between the small end of described bucker 2 and cable body 1, and in gap, insert the 3rd weather strip 7.
See Fig. 2, the present invention includes tarpaulin body 3, described tarpaulin body 3 is for breathing out furan structure and adopting stainless steel or carbon steel material to make, small end and the cable body 1 of described tarpaulin body 3 fit tightly, the front end of tarpaulin body 3 small end is provided with the first groove 8, the second weather strip 6 is provided with in described first groove 8, tarpaulin body 3 front end is bonded by the second weather strip 6 and cable body 1 and forms the first line of defence, the middle part of described tarpaulin body 3 small end is provided with the second groove 9, in described second groove 9, sealing ring 5 is installed, the middle part of tarpaulin body 3 is bonded by sealing ring 5 and cable body 1 and forms second defence line, the large end of described tarpaulin body 3 is provided with the 3rd groove 10, and have gap between the rear portion of tarpaulin body 3 and bucker 1, the first weather strip 4 is provided with in described 3rd groove 10, the rear portion of tarpaulin body 3 bonds formation three lines of defence by the first weather strip 4 with cable body 1.
Mounting means: when installing at the scene, after bucker 2 installs, on-the-spot bonding each containment member, tarpaulin body 3, by bolt tightening, ensures that the small end of tarpaulin body 3 and cable body 1 fit tightly, and guarantees that three seals component is obtained for crimp.
Operating principle: be respectively arranged with the first weather strip 4, sealing ring 5 and the second weather strip 6 in the first groove 8, second groove 9 of the present invention and the 3rd groove 10, form the three lines of defence preventing moisture content from entering, rely on sealing ring 5 to produce precommpression and be out of shape the gap adapting to Inclined Cable Vibration etc. and produce, realize the dynamic self-adapting sealing effectiveness with oblique pulling cable body 1, first weather strip 4 both can play the role of positioning, and can play again and stop that rainwater enters bucker inside.
