Description
Technical field
This utility model relates to a kind of leap the most wired Bridge Rotation Construction Technique interim tower crane structure.
Background technology
Yucheng grand bridge is crossed over Longhai Railway and is designed with rotator construction mode, and the logical long 98m of T structure that turns, bridge rotating structure is made up of lower rotary table, ball pivot, top rotary table, trailer system of turning, assist system, axis micro-tensioning system.Lower rotary table diameter 10.15m, high 1.05m；Top rotary table diameter 10.4m, high 2.5m, top rotary table ball pivot diameter 3.5m, lower rotary table ball pivot diameter 3.5m, upper and lower rotating disk all uses C50 slightly expanded concrete.Rotating part includes: top rotary table 145m3, pier shaft 387m3, beam body 1813 m3, attached 69 m of bridge floor3, add up to 2414 m3, 6276.4t.Rise the weight of mode coefficient and spike, bearing, temporary consolidation, suspension bracket etc. in view of concrete construction, rotating part gross weight about 6700t.In work progress, project management department finds that beam body deadweight is excessive, needs to use temporary support structure, but this existing line of big spanning, is not suitable for arranging Temporary Piers, and construction encounters a difficulty.
Therefore, develop a kind of problem solving temporary support and ensure the tower crane structure of quality of rotator construction, becoming the problem needing solution badly for insider.
Utility model content
For the above-mentioned technical problem in correlation technique, the utility model proposes a kind of leap the most wired Bridge Rotation Construction Technique interim tower crane structure, solve above-mentioned technical problem.
For realizing above-mentioned technical purpose, the technical solution of the utility model is achieved in that
A kind of leap the most wired Bridge Rotation Construction Technique interim tower crane structure, including the body of tower hoist with transverse arm, on described transverse arm, the one end near described body of tower hoist is provided with some drag-lines one, and the other end of this transverse arm is provided with some drag-lines two, described drag-line one and drag-line two have been fixedly connected with bridge rotating structure.
Further, described body of tower hoist is movable arm type heavy type tower crane.
Further, described drag-line one is ordinary steel drag-line.
Further, described drag-line two is high-strength steel drag-line.
The beneficial effects of the utility model: optimize rotator construction technique, the problem solving temporary support, it is ensured that the quality of rotator construction, improve efficiency of construction, similar engineering is had reference.

Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained, broadly fall into the scope of this utility model protection.
As Figure 1-3, according to a kind of leap the most wired Bridge Rotation Construction Technique interim tower crane structure described in this utility model embodiment, including the body of tower hoist 1 with transverse arm, on described transverse arm, the one end near described body of tower hoist 1 is provided with some drag-lines 1, and the other end of this transverse arm is provided with some drag-lines 23, described drag-line 1 and drag-line 23 have been fixedly connected with bridge rotating structure 4.
Wherein, described body of tower hoist 1 is movable arm type heavy type tower crane；Wherein, described drag-line 1 is ordinary steel drag-line；Wherein, described drag-line 23 is high-strength steel drag-line.
Understand technique scheme of the present utility model for convenience, below by way of in specifically used mode, technique scheme of the present utility model is described in detail.
Described drag-line 1 and drag-line 23 are all embedded in bridge rotating structure 4, then drawn by body of tower hoist 1, described body of tower hoist 1 is arranged at support end, and rotate with the angular velocity identical with described bridge rotating structure 4, described drag-line 1 is positioned at nearly support end, and described drag-line 23 is positioned at remote support end, and this layout is mainly designed according to the stress of bridge rotating structure 4, cost can be reduced as far as possible in the case of ensureing that pulling force is enough.
In sum, by means of technique scheme of the present utility model, use tower crane to replace tradition Temporary Piers, not only can serve as support means but also the traffic of construction site will not be impacted.Regulation drag-line height makes its absolute altitude identical, and during rotator construction, bridge rotating structure rotational angular velocity is identical with the angular velocity that tower crane rotates, so that tower crane runs simultaneously with tumbler.Cable wire is sling swivel structure, can offset beam body deadweight, and need not arrange Temporary Piers, traffic under middle bridge cut-off.
The foregoing is only preferred embodiment of the present utility model; not in order to limit this utility model; all within spirit of the present utility model and principle, any modification, equivalent substitution and improvement etc. made, within should be included in protection domain of the present utility model.
