Abstract
The utility model belongs to the field of bridge construction, and relates to a cable threading plate of a steel strand of a stay cable. The cable threading plate is characterized by at least comprising a connector and a cable threading plate, wherein the cable threading plate is in an arc shape, the connector is in a cylinder shape, the cable threading plate is provided with five through holes, the drift diameter of the external two through holes is the diameter of a guide rope, the drift diameter of the middle through hole is the diameter of a pulling rope, the drift diameter of the surplus two through holes at one side is the diameter of the connector, and the drift diameter at the other side is the diameter of a central upset head wire. Compared with the existing pulling device, the cable threading plate disclosed by the utility model has a simple structure, two steel strands can be pulled simultaneously, the working efficiency is improved, and at the same time twisting between the steel strands can not appear.
Description
Technical field
The utility model belongs to field of bridge construction, is a kind of suspension cable reeving steel strands plate.
Background technology
The rare rope partial cable-stayed bridge of short tower is a kind of bridge construction form between continuous rigid frame bridge and cable stayed bridge, because it has superior performance, handsome in appearance, the advantage such as economic indicator is good, at home and abroad is widely used in recent years.Existing steel strand draw-gear is simple in structure, because most suspension cables have many steel strand, can't guarantee can not twine mutually between the steel strand in the distraction procedure, and in a single day steel strand twines in distraction procedure, and consequence is very serious.
The utility model content
The purpose of this utility model provides a kind of suspension cable reeving steel strands plate.
The technical solution of the utility model is suspension cable reeving steel strands plate, it is characterized in that: which comprises at least connector and the plate of reeving, the plate of reeving is circular arc, connector is cylindrical, reeving has five through holes on the plate, and two the through hole latus rectums in outside are the guide rope diameter, and the intermediate throughholes latus rectum is the pull rope diameter, remaining two through hole one side latus rectums is the connector diameter, and opposite side is steel strand inside center heading filament diameter.
The first end of described connection can pass center heading silk, and the other end has a screw-casing, center heading silk can be fixed connector and reeving between the plate without annexation.
Described plate and the connector of reeving is steel.
Characteristics of the present utility model are: compare with existing draw-gear, the utility model is simple in structure, can draw simultaneously two steel strand, also can guarantee can not twine between the steel strand when increasing work efficiency.
Description of drawings
The present invention is further illustrated below in conjunction with specific embodiment:
Fig. 1 is constructional drawing of the present utility model.
Among the figure, 1, guide rope; 2, pull rope; 3, connector; 4, the plate of reeving; 5, center heading silk; 6, steel strand.
The specific embodiment
Embodiment 1
Suspension cable reeving steel strands plate, it is characterized in that: which comprises at least connector 3 and the plate 4 of reeving, the plate 4 of reeving is circular arc, connector 3 is cylindrical, reeving has five through holes on the plate 4, and two the through hole latus rectums in outside are guide rope 1 diameter, and the intermediate throughholes latus rectum is pull rope 2 diameters, remaining two through hole one side latus rectums is connector 3 diameters, and opposite side is steel strand 6 inside center heading silks 5 diameters.
Embodiment 2
Substantially the same manner as Example 1, difference is: connector 3 one ends can pass center heading silk 5, and the other end has a screw-casing, can center heading silk 5 is fixing, and connector 3 and reeve and there is no annexation between the plate 4.Plate 4 and the connector 3 of reeving is steel.
During use, will reeve plate 4 two ends and bridge floor steel wire rope of windlass are connected to form a closed loop trailer system; After steel strand 6 blankings are finished, the PE sheath at steel strand 6 two ends is peeled off and steel strand 6 outside six roots of sensation steel wires are excised, only stay core wire heading 5, use for the hanging cable traction; Emit steel strand 6 from pay off rack, one of steel strand 6 are terminated on the connector 3, tighten connector 3 steel strand are locked; Start hoist engine, plate 4 traction of will reeving is advanced drag-line HDPE outer tube and is carried out steel strand 6 construction of reeving.
The parts that present embodiment is not described in detail and structure belong to well-known components and common structure or the conventional means of the industry, here not one by one narration.
