Description
Technical field
The invention belongs to bridge structure technical field of construction, it is related to a kind of bridge construction temperature pier measure, especially relates to
And to it is a kind of prevent cord clip of suspension bridge slide device.
Background technology
Cord clip is the key member of suspension bridge, and its effect is that suspension rod is connected on main push-towing rope, and the pulling force of suspension rod is transmitted
To main push-towing rope.Because main push-towing rope is shaped form, under steeve tension effect, the power that cord clip is produced to main push-towing rope includes vertical main push-towing rope direction
Pressure and the sliding force along main push-towing rope direction, wherein sliding force undertake by the frictional force between cord clip and main push-towing rope.Specification specifies bridge
Design service life is 100 years, but, because burn into is aging etc., the reason life-span does not reach 100 years hoist cable, and it makes in Bridge Design
With needing during the life-span to change.In fact, the suspension rod of domestic many suspension bridges is just changed using 10 years or so.More
Change in hanger construction, when a certain suspension rod is removed, the pulling force of the suspension rod will distribute to the adjacent suspension rod in its both sides, so as to make
Pulling force into adjacent suspension rod increases by more than 40%.Steeve tension increase is likely to cause cord clip anti-slide performance not enough, causes rope
Folder sliding failure, this not only results in main push-towing rope protection damage layer, or even jeopardizes bridge structure and workmen's safety.To ensure rope
Folder does not produce sliding, and current solution is generally increases an interim cord clip below the cord clip that may be glided, the method
Have the disadvantage to need destruction main cable protection layer, and installation and removal trouble.
