Abstract
The utility model particularly relates to a prestress steel stranded wire, which belongs to the technical field of metal wires and has the main technical scheme that because the prestress steel stranded wire comprises a middle wire body, a plurality of strands of outer steel wires with the diameter being 3.0 to 5.8mm are arranged around the middle wire body, the outer steel wires are wound outside the middle wire body and are mutually twisted, and in addition, the periphery of the prestress steel stranded wire is in a spiral concave-convex shape, the bonding strength of concrete and the prestress steel stranded wire is strong, the concrete is not easy to fall off, the integral tensile strength is greatly enhanced, and meanwhile, the service life of the prestress steel stranded wire is prolonged.
Description
Technical field
The utility model belongs to the metal wire rod technical field, relates in particular to a kind of prestress wire.
Background technology
In fields such as building, highway, railway, bridges, prestressing force is more and more wider with the application of product, prestressing force adopts metallic bones with product, prestressing force comprises two kinds with the skeleton of product: one, and short or requirement of strength is not high with product for length, adopt that single screw-thread steel or many screw-thread steels are end to end to weld together, like this, the weld bond place intensity of welding is low, poor corrosion resistance, fracture easily.
The utility model content
The technical problem that the utility model solves just provides a kind of do not have length restriction, prestress wire that tensile strength is big.
The technical scheme that the utility model adopted is:
Filament in the middle of comprising is provided with the multiply diameter in the middle of described and is 3.0-5.8 millimeters outer steel wire around the filament, the outer steel wire of described multiply is wrapped in the external side of described intermediate filament and wringing is together mutually.
Described outer steel wire is 6 strands.
Prestress wire provided by the utility model compared with prior art, have the following advantages: because filament in the middle of comprising, be provided with the multiply diameter in the middle of described around the filament and be 3.0-5.8 millimeters outer steel wire, the outer steel wire of described multiply is wrapped in the also mutual wringing of the external side of described intermediate filament together, and the prestress wire periphery is the spiral embossing shape, concrete and prestress wire adhesive strength are big, concrete is not easy to come off, whole tensile strength can strengthen greatly, simultaneously, prolonged its service life.
Description of drawings
As Fig. 1 is the structural representation of prestress wire provided by the utility model;
Fig. 2 is the sectional view of prestress wire.
The specific embodiment
Be described in further details below in conjunction with the structure of accompanying drawing prestress wire provided by the utility model.
As depicted in figs. 1 and 2, be the structural representation of the prestress wire that the utility model proposed.Filament 2 in the middle of comprising, being provided with six strands of diameters around middle filament 2 is 3.0-5.8 millimeters outer steel wire 1, filament 2 outsides and mutual wringing were together in the middle of outer steel wire 1 was wrapped in, like this, the prestress wire periphery is the spiral embossing shape, and concrete and prestress wire adhesive strength are big, concrete is not easy to come off, whole tensile strength can strengthen greatly, simultaneously, has prolonged its service life.
Outer steel wire 1 is 6 strands, and like this, it is best that prestress wire diameter that obtains after the winding and tensile strength can both reach, and this moment is more firm with concrete bonding.
Claims (2)
1. prestress wire, filament in the middle of comprising is characterized in that: be provided with the multiply diameter in the middle of described around the filament and be 3.0-5.8 millimeters outer steel wire, the outer steel wire of described multiply is wrapped in the external side of described intermediate filament and wringing is together mutually.
2. prestress wire according to claim 1 is characterized in that: described outer steel wire is 6 strands.
