Abstract

The utility model discloses a large-diameter spiral ribbed steel wire, which belongs to the technical field of steel wires. The large-diameter spiral ribbed steel wire is mainly technically characterized by comprising a steel wire body with an 8-12mm diameter and at least two spiral ribs, and the ribs are disposed at equal intervals on the lateral side of the steel wire body, and are 0.7-0.8mm in height, 2.2-3.0mm in width and 40-60mm in pitch. Therefore, adhesion strength of concrete workpiece made of the steel wire with concrete is guaranteed, and the integral tensile strength is not reduced further.

Description

The major diameter helix rib steel wire

Technical field

The utility model belongs to the wire technique field, relates to the major diameter helix rib steel wire concretely.

Background technology

In fields such as building, speedway, 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; Its two, adopt the helix rib steel wire have as skeleton with product, the helix rib steel wire that uses at present, have following shortcoming: 1, in order to increase and concrete adhesive strength, spiral ribs is higher, makes the hot strength of steel wire be affected; 2, spiral ribs is lower, though reach hot strength,, reducing with concrete bonding intensity, concrete comes off easily.

The utility model content

The technical problem that the utility model solves just provides a kind of and concrete bonding intensity is big, tensile strength strong, the major diameter helix rib steel wire of long service life.

For solving the problems of the technologies described above, the technical scheme that the utility model proposes is: comprise that diameter is 8-12 millimeters steel wire body and is positioned at this steel wire body side at least two spiral fins of same distance at interval, the height of described spiral fin is 0.7-0.8 millimeter, the width of spiral fin is 2.2-3.0 millimeters, and the pitch of spiral fin is 40-60 millimeters.

Its additional technical feature is:

Described spiral fin is four, and the height of described spiral fin is 0.73-0.78 millimeter, and the width of spiral fin is 2.24-2.26 millimeters, and the pitch of spiral fin is 51-55 millimeters.

The major diameter helix rib steel wire that the utility model provides, compare with prior art and to have the following advantages: one, because comprising diameter is 8-12 millimeters steel wire body and is positioned at this steel wire body side at least two spiral fins of same distance at interval, the height of described spiral fin is 0.7-0.8 millimeter, the width of spiral fin is 2.2-3.0 millimeters, the pitch of spiral fin is 40-60 millimeters, like this, both guaranteed that steel wire makes with product skeleton and concrete adhesive strength, make whole tensile strength not reduce again; Its two because described spiral fin is four, the height of described spiral fin is 0.73-0.78 millimeter, the width of spiral fin is 2.24-2.26 millimeters, the pitch of spiral fin is 51-55 millimeters, adhesive strength and tensile strength reach optimum state.

Description of drawings

The structural representation of Fig. 1 major diameter helix rib steel wire;

Fig. 2 is the sectional view of major diameter helix rib steel wire.

The specific embodiment

Be described further below in conjunction with the structure of accompanying drawing the major diameter helix rib steel wire that the utility model proposed.

As depicted in figs. 1 and 2, be the structural representation of major diameter helix rib steel wire.Its structure comprises that diameter is 8-12 millimeters steel wire body 1 and the spiral fin 2 that is positioned at this steel wire body 1 side, interval same distance, spiral fin 2 can be many more than two, as depicted in figs. 1 and 2, spiral fin 2 is four, the height of spiral fin 2 is 0.7-0.8 millimeter, the width of spiral fin 2 is 2.2-3.0 millimeters, the pitch of spiral fin 2 is 40-60 millimeters, like this, both guaranteed that steel wire makes with product skeleton and concrete adhesive strength, make whole tensile strength not reduce again.

In order to make adhesive strength and tensile strength reach optimum state, the height of spiral fin 2 is 0.73-0.78 millimeter, and the width of spiral fin 2 is 2.24-2.26 millimeters, and the pitch of spiral fin 2 is 51-55 millimeters.
