Abstract
The invention discloses a steel strand pulling device, which is characterized by comprising a tensile stress component (1), wherein a pulling ring (2) is arranged at one end of the tensile stress component (1); an internal thread is arranged on the inner wall of the tensile stress component (1); a reinforced component (3) with an external thread is in threaded matching with the tensile stress component (1); a cone-shaped through hole is formed in the reinforced component (3), and a shearing stress component (4) matched with the cone-shaped through hole is arranged; the shearing stress component (4) can perform elastic deformation in the radial direction; the inner diameter of the shearing stress component (4) is matched with the outer diameter of a steel strand; a plurality of annular textures are formed on the inner diameter surface of the shearing stress component (4). The steel strand pulling device is simple in structure and unique in design, and utilizes the method that shearing stress is transformed into compressive stress to pull out the steel strand from a rubber rod with the dependence on friction force.
Description
Technical field
The present invention relates to a kind of aid of applying while using steel strand, particularly a kind of steel strand pull device.
Background technology
In the work progress of prestressed concrete box girder, steel strand in rubber bar need to be pulled out, traditional pulling mode can cause the end portion of steel strand that irregular flexural deformation occurs, this distortion can cause steel strand can't carry out the secondary use, cause shorten the service time of steel strand, wasted a large amount of resources.Therefore need now a kind of can by steel strand when rubber bar, pulling smoothly out, guarantee device or method that its end portion can not deform.
Summary of the invention
The present invention is in order to solve the existing above-mentioned deficiency of prior art, proposes a kind of simple in structurely, designs ingeniously, utilizes shearing stress to be converted into the mode of compressive stress, relies on frictional force that steel strand are pulled to device from the steel strand that pull rubber bar out.
Technical solution of the present invention is: a kind of steel strand pull device, it is characterized in that: described pulling device comprises tensile stress member 1, an end at tensile stress member 1 is provided with pulling ring 2, on the inwall of tensile stress member 1, be provided with internal thread, being provided with externally threaded strenthening member 3 matches with tensile stress member 1 screw thread, in strenthening member 3, offer the taper through hole, with the taper through hole matches, be provided with shearing stress member 4, elastic deformation can occur in shearing stress member 4 diametrically, the internal diameter of shearing stress member 4 and the external diameter of steel strand match, and also be provided with a plurality of ring-type lines on the surface of shearing stress member 4 internal diameters.
Described along the symmetrical twice joint-cutting 5 of axially offering of shearing stress member 4.
The present invention compared with the existing technology, has following advantage:
The steel strand of this kind of form of structure pull device, and it is simple in structure, designs ingenious, rationally distributed.It need to carry out bending to the end portion of steel strand in traditional steel strand pulling process, causes the problem of steel strand generation loss, designs a kind of structure of utilizing frictional force to pull steel strand.The pulling force that the pulling device of this structure produces the tensile stress member is by strenthening member and the acting in conjunction of shearing stress member, be converted into shearing stress, again this part shearing stress is converted into to compressive stress, thereby reach the purpose that increases frictional force between steel strand and shearing stress member internal diameter, utilize this frictional force by steel strand from rubber bar, pulling out, the spoilage of steel strand is 0 in this case, and namely it can pull it under the prerequisite of not damaging steel strand, so that the secondary of steel strand is used.And its assembling is simple, cheap, and applicability is wide, therefore can say that it has possessed multiple advantage, be particularly suitable for applying in the art, its market prospects are very wide.
The accompanying drawing explanation
Fig. 1 is the front view of the embodiment of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing explanation the specific embodiment of the present invention.As shown in Figure 1: a kind of steel strand pull device, it comprises tensile stress member 1, an end at tensile stress member 1 is provided with the pulling ring 2 for pulling, and be provided with internal thread on the inwall of tensile stress member 1, being provided with externally threaded strenthening member 3 matches with tensile stress member 1 screw thread, in strenthening member 3, offer the through hole of taper, with this taper through hole matches, be provided with shearing stress member 4, the internal diameter of this shearing stress member 4 and the external diameter of steel strand match, elastic deformation can occur in shearing stress member 4 diametrically simultaneously, shearing stress member 4 can have the various structures form, wherein a kind of structure is axially to offer the symmetrically arranged joint-cutting 5 of twice along shearing stress member 4, when shearing stress member 4 is subject to extruding radially, joint-cutting 5 diminishes, and the surface at the internal diameter of shearing stress member 4, also be provided with a plurality of ring-type lines, for increasing friction force.
The course of work that the steel strand of the embodiment of the present invention pull device is as follows: at first shearing stress member 4 is socketed on steel strand, then shearing stress member 4 is enclosed within strenthening member 3, and strenthening member 3 is threaded in tensile stress member 1, finally draw-gear is connected with pulling ring 2, when draw-gear pulls tensile stress member 1, tensile stress member 1 drives strenthening member 3 and moves with respect to steel strand, owing in strenthening member 3, offering the taper through hole matched with shearing stress member 4, therefore when relative displacement occurs with shearing stress member 4 in strenthening member 3, elastic deformation can occur in the shearing stress member 4 of taper, joint-cutting 5 diminishes, socket steel strand are within it carried out to the extruding that footpath makes progress, because the inside diameter surface of shearing stress member 4 is provided with a plurality of ring-type lines, therefore can provide enough large frictional force, in 1 motion of tensile stress member, by steel strand from rubber bar, pulling out.
