Description
Technical field
The utility model relates to a kind of stay cable force super to put a structure.
Background technique
The main road Zhong Tie hondo bridge is " reed-pope wind instrument " moulding cable-stayed bridge, linear and the bridge construction stage in order to preferably optimize
Upper and lower fiber stress improves bridge service life, therefore before cable-stayed bridge closure, design requirement is by every skew cables Suo Li using single top
It is first temporarily stretched to the 0.46fpk of stay cable force, puts a structure for stay cable force super using super before closure section closure
It is pulled to 0.65fpk, after full-bridge prestress system converts, continues to 0.72fpk then to use stay cable force super
It puts a structure and puts stay cable force for super and open to 0.56fpk, realize the optimization of and box beam linear to full-bridge or more fiber stress.It passes
The preceding cassette list of system, which takes out top, will realize that stay cable force super puts an adjustment, and constructing operation difficulty is big, low in economic efficiency, and
It is impaired that single top adjustment is easy to cause suspension cable PE epoxy coating strand, therefore has developed that a kind of stay cable force is super to put a structure.
Utility model content
Technical problem to be solved by the utility model is: providing a kind of stay cable force super puts a structure, comparison tradition
The method of single top adjustment Suo Li, list top adjustment Suo Li are to reach release Suo Li by torsion adjusting nut, then use single top to every
To Suo Li design value, the difficulty for reversing adjusting nut is big for tensioning one by one for steel strand wires, and adjustment progress is slow and effect is poor.This is practical new
It puts a structure and realizes the whole beam steel strand wires of suspension cable while surpassing to open and put for a kind of stay cable force of type super and open, and adjusting nut
It is easy suitable or counter-clockwise rotation, improves stay cable force adjustment progress.A kind of stay cable force of the utility model super puts
Locking device in structure solves steel strand wires either ultra stretching when still putting tensioning operating condition, the position of intermediate plate and steel strand wires
It is constant, it effectively prevent work clip sheet to crush steel strand wires.
The technical solution of the utility model is: a kind of stay cable force super puts a structure comprising guide pipe, partition wall tooth
Block concrete, anchorage drum, guide pipe anchor slab work anchor and adjusting nut, guide pipe are embedded in box beam mid-board tooth block concrete
Interior, anchorage drum is set in guide pipe, and guide pipe anchor slab, adjusting nut and work anchor, partition wall tooth are successively installed in guide pipe one end
Block concrete setting adjusting nut side fixed setting steel support stretching bed seat, steel support stretching bed seat other end connection jack, thousand
Jin top other end fastening means anchor.
The locking device is connected by connection bolt and ring flange with anchorage drum, and adjustment hole rotates upwardly and downwardly for adjusting nut
Effect.
The guide pipe meets second-order weld requirement using welding, welded seam grade.
The steel support stretching bed seat is by round upper plate, left arc panel, right circular arc panel and triangle batten plate
Composition, is separately connected left arc panel and right circular arc panel, triangle batten plate is respectively welded below round upper plate
In the junction of round upper plate and left arc panel and right circular arc panel.
The steel support stretching bed seat passes through left arc panel and right circular arc panel and box beam mid-board tooth block respectively
Concrete connection.
The steel support stretching bed seat uses Q235 steel plate to process.
The circular hole that a diameter is 20cm is arranged in the center of round upper plate in the steel support stretching bed seat.
The jack is hydraulic feed-through jack.
It in ultra stretching and puts and sets up bracket below tension structure, using the fixed ultra stretching of chain block and put tension structure dress
It sets.Jack oil the cylinder piston is stretched out at super, and adjusting nut is separated with guide pipe anchor slab, and gap becomes larger, and torsion is adjusted clockwise
Nut is saved, realizes that adjusting nut anchors suspension cable.When putting, first by suspension cable super, adjusting nut and guide pipe anchor slab point
From reversing adjusting nut counterclockwise and it become larger with guide pipe gap, jack oil the cylinder piston retraction is adjusted to putting vang force value
Afterwards, torsion adjusting nut makes it be close to realize to suspension cable anchoring with guide pipe anchor slab clockwise.
The beneficial effects of the utility model are as follows:
1, constructional device is combined into using steel support stretching bed seat, centre-hole jack, adjusting nut, work anchor and moveable anchor
Ultra stretching is carried out to suspension cable and puts tensioning cable force adjustment, single top adjustment stay cable force is avoided, turns adjusting nut difficulty
Big and adjustment Suo Li inefficiencies defects preferably ensure that suspension cable ultra stretching and put the operation safety and adjustment rope of tensioning
The accuracy of power creates good economic benefit.
2, the installation of locking device ensures the position of intermediate plate and steel strand wires when steel strand wires either ultra stretching still puts tensioning
It is absolutely constant, it prevents work clip sheet from crushing steel strand wires, the service life of steel strand wires is effectively guaranteed.
