Abstract
The present invention relates to a stranded wire puller. It includes an anchor main body and a pulling ring connected with stranded wire. It is characterized by that said anchor main body is made into the form of cylinder body whose interior is formed into cone form. In the interior of said anchor main body two clips and one pull rib are mounted, the end portion of said pull rib is connected with pulling ring. Said invention can be used in the superlong post-stressed concrete construction, and can be used for making stranded wire be smoothly passed through corrugated pipe.
Description
(1) technical field
The present invention relates to a kind of construction tool, particularly a kind of steel strand retractor that draws steel strand.
(2) background technology
In the construction of overlength post-tensioned concrete structure, it is more that the steel strand in the bellows are provided with quantity.Because steel strand are comparatively soft, are difficult for passing bellows, the general employing worn-installation technology that drawknot closes in the construction.Traditional mounting process installation effect is bad and installation rate is slower.
(3) summary of the invention
The purpose of this invention is to provide a kind of steel strand retractor, mainly solve in the construction of overlength post-tensioned concrete structure, steel strand are difficult to pass rapidly the problem of bellows.
The object of the present invention is achieved like this: comprise anchoring main body and the draw ring that is connected steel strand, it is characterized in that: its anchoring main body is that an inside is taper shape, the microcephaly of circular cone is towards the cylindrical shell of lead, the wedge shape intermediate plate that draws muscle is dragged in inner barrel at least two clampings of packing into, the outer wall of intermediate plate is bound round together, the interior armlet of intermediate plate draws the muscle periphery dragging, drag and draw muscle outside lead extends to cylindrical shell, the also fixedly connected tractive muscle of the outer wall of cylindrical shell, the tractive muscle extends to the opposite direction of traction, the end of tractive muscle is a ring tab shape, and draw ring is connected with trailed steel strand kink.
Above-mentionedly drag that to draw muscle be wire rope or steel strand.
The outer wall of above-mentioned intermediate plate has the stirrup groove, by stirrup with the intermediate plate hoop together.
Using method of the present invention is as follows:
(1), wear first steel strand time ratio and be easier to, 1# steel strand retractor draw ring is connected with the front end of first steel strand, pull dragging of steel strand retractor and draw the muscle front end, drive first steel strand and take pipe outlet to from entrance, run through whole pipe;
(2), the draw ring with the 2# steel strand retractor is connected with the front end of second steel strand;
(3), pull dragging of 2# steel strand retractor at pipe outlet and draw muscle, second steel strand brought in the pipeline;
(4), simultaneously,, unload the intermediate plate of 1# steel strand retractor, the 1# steel strand retractor is returned to entrance be connected on the 3rd steel strand at pipe outlet;
(5), pull dragging of 2# steel strand retractor at pipe outlet and draw muscle, the wire rope of the 3rd steel strand and 1# steel strand retractor is brought in the pipeline;
(6), repeat above-mentioned steps, whole steel strand are drawn to pipeline.
The present invention compares the beneficial effect that has with existing conventional art: in the construction of overlength post-tensioned concrete structure, can make steel strand pass bellows smoothly, fast, thereby improve speed of application.
(4) description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is an internal construction schematic diagram of the present invention;
Fig. 3 is that the structural representation that draws muscle is dragged in the intermediate plate clamping;
Fig. 4 is that the lateral view that draws muscle is dragged in the intermediate plate clamping.
Among the figure: 1-drags and draws muscle, 2-cylindrical shell, 3-draw ring, 4-steel strand, 5-intermediate plate, 6 stirrups, 7-tractive muscle.
(5) specific embodiment
Embodiment is referring to Fig. 1-4, this steel strand retractor, comprise anchoring main body and the draw ring that is connected steel strand, its anchoring main body is that an inside is the cylindrical shell 2 of the microcephaly of taper shape, circular cone towards lead, the wedge shape intermediate plate 5 that draws muscle is dragged in inner barrel two clampings of packing into, the outer wall of intermediate plate has the stirrup groove, by stirrup 6 with the intermediate plate hoop together.The interior armlet of intermediate plate draws muscle 1 periphery dragging, drag and draw muscle and extend to outside the cylindrical shell along lead (direction of arrow), the also fixedly connected tractive muscle 7 of the outer wall of cylindrical shell, the tractive muscle extends to the opposite direction of traction, the end of tractive muscle is a ring tab shape, and draw ring 3 is connected with trailed steel strand 4 kinks.Above-mentionedly drag that to draw muscle 1 can be wire rope or steel strand.
Using method of the present invention is as follows:
(1), wear first steel strand time ratio and be easier to, 1# steel strand retractor draw ring is connected with the front end of first steel strand, pull dragging of steel strand retractor and draw the muscle front end, drive first steel strand and take pipe outlet to from entrance, run through whole pipe;
(2), the draw ring with the 2# steel strand retractor is connected with the front end of second steel strand;
(3), pull dragging of 2# steel strand retractor at pipe outlet and draw muscle, second steel strand brought in the pipeline;
(4), simultaneously,, unload the intermediate plate of 1# steel strand retractor, the 1# steel strand retractor is returned to entrance be connected on the 3rd steel strand at pipe outlet;
(5), pull dragging of 2# steel strand retractor at pipe outlet and draw muscle, the wire rope of the 3rd steel strand and 1# steel strand retractor is brought in the pipeline;
(6), repeat above-mentioned steps, whole steel strand are drawn to pipeline.
