Description

Torsion steel fiber manufacturing apparatus having a polygonal cross section {MANUFACTURING APPARATUS OF POLYGONAL TWISTED STEEL FIBER}

The present invention relates to a steel fiber for reinforcing concrete used in civil engineering structures such as tunnels, bridges and road pavements, and various building structures, and more specifically, to increase the contact strength between the concrete and the steel fiber to increase the compressive strength and tension of the concrete. In order to enhance the strength and impact strength, as well as to improve the durability, the steel fibers mixed into the concrete are manufactured by a torsional steel fiber manufacturing apparatus. In the torsional steel fiber manufacturing apparatus, the steel wire is formed in a predetermined cross-sectional shape as well as in the longitudinal direction. After twisting and forming, the steel wire having the predetermined cross-sectional shape, which is twisted and formed, is not only easily and easily manufactured to the torsional steel fiber cut to a certain length, but also a polygonal cross section which enables mass production of the torsional steel fiber. With twisted steel fiber It relates to an apparatus.

Generally, reinforcement or wire mesh is installed in a structure before placing concrete to construct civil structures such as tunnels, bridges or road pavements, and various building structures, and then place concrete where the reinforcement or wire mesh is installed. Then, after a certain curing time has elapsed, the poured concrete is attached to the rebar or wire mesh.

As the concrete constructed as described above simply uses only reinforcing bars or wire mesh, durability, tensile strength, and impact strength are low, so that when the concrete is subjected to a certain impact, the concrete is not only cracked or broken, but also cracked or broken. When impurities or water penetrate through the steel, the reinforcing wires or wire meshes are corroded, thereby reducing the strength of concrete and shortening the lifespan.

So, in recent years, before reinforcing concrete, reinforcing steel fiber (Steel fiber) is mixed into the concrete, while compressing, tensile strength and impact of the concrete while reducing the cross-sectional area of the concrete by the steel fiber mixed in the concrete. It not only enhances the strength, but also improves the durability, and also reduces the construction cost.

However, the reinforcing steel fiber used in mixing with the concrete uses a straight steel fiber having a straight shape without any deformation in the direction of the length, or a hooked shape in which a hook-shaped deformation is introduced at both ends of the steel fiber. The cross section of the existing steel fiber is formed in a circular shape.

Therefore, the steel fiber is not enough to reinforce the compression, tensile strength and impact strength and durability of the concrete, as the contact strength between the concrete and the existing steel fiber is lowered as the sliding phenomenon with the concrete occurs. There was also a problem that the construction cost increases as a large amount of steel fibers to be mixed to reinforce the concrete.

As the timing pulley 342 is rotated, the lower roller 33 is also rotated, and the upper roller 32 is rotated in a direction opposite to the lower roller 33.

When rotating the adjusting bolt 344 installed on the upper portion of the support 31, the upper roller 32 is reciprocated in the vertical direction between the outer peripheral surface of the upper roller 32 and the outer peripheral surface of the lower roller 33 Since the contact force is adjusted, the rotational speed of the upper and lower rollers 32 and 33 and the force for rolling the steel wire a drawn between the upper and lower rollers 32 and 33 are adjusted.
