Description
Technical field
The utility model belongs to bridge field, relates to cable of space cable suspension bridge, is specifically related to a kind of cable of space cable suspension bridge false stull.
Background technology
Traditional suspension bridge is generally plane rope shape earth anchored suspension bridge, comprises main push-towing rope, hoist cable, stiff girder, king-tower and main push-towing rope anchorage element.Main push-towing rope and hoist cable are positioned at same vertical plane and form a cable rope face, and main push-towing rope only has vertical sag and there is no horizontal sag, and all hoist cable verticals hang and there is no a direction across bridge inclination angle.Tradition suspension bridge is often comprised of two cable rope faces that are parallel to each other.Tradition suspension bridge adopts lifting construction, i.e. " First cable later girder " method, and step is as follows: ①Mao sets up main push-towing rope on road, and main push-towing rope is now linear is called sky cable shape; 2. hoist cable cord clip is installed on main push-towing rope; 3. hoist cable is installed, and the upper end of hoist cable is connected with cord clip; 4. lift stiff girder, in hoist cable lower end lifting stiff girder beam section, until all beam sections have lifted, now temporarily hinged between each beam section; 5. adjust stiff girder linear, be welded as integral body; 6. cat road is mated formation, removed to the second phase.
Because traditional main rope of suspension bridge and hoist cable are positioned at same vertical plane, so in above-mentioned lifting construction process, 2. the installation of hoist cable cord clip is without considering direction across bridge inclination angle for step, directly in cable rope face, vertical positioning instant can.
Relatively traditional suspension bridge, the feature of cable of space cable suspension bridge maximum is: the face that main push-towing rope and hoist cable form is a space curved surface, and main push-towing rope not only has vertical sag to also have horizontal sag, and hoist cable direction across bridge is different towards outer incline and inclination angle from top to bottom.
Cable of space cable suspension bridge is because the hoist cable that direction across bridge tilts pulls open main push-towing rope to a certain extent, the hoist cable of cable of space cable suspension bridge and main push-towing rope all have to be protected to power, the hoist cable that direction across bridge tilts and stiff girder form a stable triangle, direction across bridge horizontal component in every pair of oblique hoist cable is clamped stiff girder, make girder have the restoring force of similar pendulum, thereby improve whole torsional stiffness.Its dynamic performance superiority of cable of space cable suspension bridge, wind loading rating is strong, and its linear grace, and moulding is novel, favored by people.
The advantage of cable of space cable suspension bridge lifting construction: according to the difference of anchor type, cable of space cable suspension bridge can be divided into ground anchor type and self-anchoring type.
For cable of space cable earth anchored suspension bridge, can build according to " First cable later girder " construction method of plane rope shape earth anchored suspension bridge.
For cable of space cable self-anchored suspension bridge, traditional construction method is " cable after first beam ", set up support---on > support, setting up girder---> sets up main push-towing rope, main push-towing rope two ends are anchored in beam-ends---> stretch-draw hoist cable---the > second phase mats formation---> striking.This method, owing to must setting up full framing, is inevitably disturbed navigation channel or road traffic, and exists large span to set up high, the problem such as unsafe factor is many, safety and duration risk height for timbering cost.
By adopting relevant temporary measure, cable of space cable self-anchored suspension bridge also can be built by " First cable later girder " construction method, so not only avoids economy and the safety problem brought because setting up support, and the while can be avoided the interference to traffic such as navigation channels.
The problem that cable of space cable suspension bridge lifting construction need to overcome: for cable of space cable suspension bridge, no matter adopt still " First cable later girder " method of " cable after first beam " method, there is the following problem that needs solution in capital: the empty cable state after main push-towing rope sets up is plane rope shape, only have vertical sag there is no horizontal sag, differ greatly in direction across bridge position with becoming the Spatial Cable shape under bridge state.Therefore, the cord clip direction across bridge inclination angle that need to adjust when hoist cable cord clip is installed is larger, controls difficulty high, to such an extent as to hoist cable otic placode cannot insert cord clip otic placode, cause hoist cable to install, even if be inserted in cord clip otic placode and the bending that easily generation is larger of hoist cable otic placode place, reduce the application life of hoist cable.
Cable of space cable suspension bridge for the construction of " cable after the first beam " method of employing, current solution is to adopt interim hoist cable that empty cable is laterally outwardly opened, it is linear that the cable shape that makes to have leisure approaches into bridge at direction across bridge, and then installation hoist cable cord clip, the operations such as stretch-draw hoist cable, remove interim hoist cable after waiting the second phase to mat formation.The interim upper end of hoist cable and the interim hoist cable cord clip of main push-towing rope are connected, and lower end is fixed on the girder of having constructed.
Above-mentioned interim hoist cable scheme needs lower end anchorage support, but the cable of space cable suspension bridge of constructing for " First cable later girder " method of employing, because girder is not yet constructed, does not exist lower end anchorage support, therefore interim hoist cable scheme cannot be used.In addition, unobstructed in order to guarantee the traffic such as navigation channel, interim lower end anchorage support is set and certainly will blocks the traffic such as navigation channel, therefore interim hoist cable scheme cannot be used equally.
Summary of the invention
The problem existing for prior art, the purpose of this utility model is to provide a kind of stull for cable of space cable suspension bridge lifting construction, make in steel case beam hoisting process, without by the pre-deflection of hoist cable cord clip, both can guarantee that hoist cable otic placode inserted cord clip otic placode smoothly, hoist cable is installed and carried out smoothly, can guarantee that again cord clip otic placode and hoist cable otic placode do not produce bending, do not affect the application life of hoist cable.
