Reinforcement for reinforced concrete and methods for manufacturing thereof |
摘要 |
Disclosed a reinforcement structure for reinforced concrete and methods for manufacturing thereof. In one aspect, the reinforcement structure includes a rod comprising a spiral strip having a pitch between 1.0 and 10.0 times a width of the strip and a ratio of thickness of the strip to the width of the strip in a range of 1:4 to 1:10. The surface of the spiral strip may be entirely or partially corrugated with ribs of arbitrary shape and having height in a range of 0.05% to 0.30% of the thickness of the strip. In another aspect, method for manufacturing a reinforcement structure comprises flattening a wire rod into a flat strip, corrugating it with ribs, and twisting the ribbed strip into a spiral of the specified pitch. |

1. A reinforcement for reinforced concrete, comprising
a multi-flanged uniform solid metal spiral rod having a star-shaped cross-section and having three or more flanges that spiral longitudinally along a length of the rod, wherein the spiral has a pitch between 1.0 and 10.0 times a diameter of a cylinder into which the spiral rod is inscribed; wherein a ratio of thickness of one of the three or more flanges to the diameter of the cylinder is in a range of 1:4 to 1:10; and wherein at least one surface of at least one flange of the rod has a plurality of ribs having a height in a range of 0.05% to 0.30% of the thickness of the flange. |
