Description
Technical field
The utility model belongs to and waters the box bridge technical field of construction, particularly relates to a kind of cast-in-situ box girder overlength stretch-draw penetrating device.
Background technology
At present, cast-in-situ box girder overlength stretch-draw penetrating device is to adopt the single steel strand termination to carry out adhesive tape to twine, the manually method construction of importing into by root.There is following technical disadvantages in this method: 1, efficiency of construction is low, twines adhesive tape by root, wastes time and energy, and has a strong impact on construction period and programming.2, cost of production height except efficiency of construction is low, also needs a large amount of manually, has increased cost of production.3, the injury to bellows is big, takes adhesive tape to twine the steel strand termination and carries out lashing, destroys bellows easily, because steel strand are longer, breakdown point is difficult for being found, and produces hidden danger of quality.4, steel strand penetrate the wrong phenomenon of twisting in a branch of steel strand of easy appearance by root, increase the coefficient of friction resistance in duct, make follow-up stretch-draw numerical value inaccurate.5, can only be applied to general steel strand, then can't finish the lashing construction for super-length prestressed muscle.
Summary of the invention
The utility model provides a kind of cast-in-situ box girder overlength stretch-draw penetrating device for solving the technical problem that exists in the known technology.
The purpose of this utility model provides a kind of simple in structure, easy construction, and the steel strand lashing destroys little to bellows, and wrong the twisting of steel strand lacked easy disassembling, the cast-in-situ box girder overlength stretch-draw penetrating device of characteristics such as efficiency of construction height.
The technical scheme that the utility model cast-in-situ box girder overlength stretch-draw penetrating device is taked is:
A kind of cast-in-situ box girder overlength stretch-draw penetrating device, be characterized in: the stretch-draw penetrating device comprises hauling power device, rope, steel cap device, lifting servicing unit, hauling power device links to each other with rope, rope links to each other with the steel cap device, the steel cap device is used for connecting steel strand, and the lifting servicing unit is used for the auxiliary lashing of lifting steel strand.
The utility model cast-in-situ box girder overlength stretch-draw penetrating device can also adopt following technical scheme:
Described cast-in-situ box girder overlength stretch-draw penetrating device, be characterized in: hauling power device is connected by rigging with rope, and rigging tightens together draw-gear and rope.

The concrete course of work of present embodiment:
The job practices of the utility model cast-in-situ box girder overlength stretch-draw penetrating device comprises following work progress:
1) the steel strand blanking that at first will carry out lashing is placed by the cast-in-situ box girder; Several a branch of steel strand are linked to each other with intelligent steel cap by the extruding anchor.
2) hauling power device is installed, hauling power device is positioned over place, one section permanent position of bridge;
3) traction power is linked to each other with rope;
4) rope is drawn in bellows to box girder body 3 other ends at box girder body 3 one ends;
