Rebar form factor: the surface shape and size ribbed steel tolerances. Ribbed steel horizontal rib design principles should meet the following requirements: the angle β transverse ribs and reinforced axis of not less than 45 degrees 9.5mm steel models, when the angle of not more than 70 degrees, on opposite sides of the cross rib reinforcement direction be contrary; transverse ribs is not greater than the nominal spacing l reinforced 0.7 times the nominal diameter; transverse ribs and reinforced side surface of the angle α of not less than 45 degrees; reinforced the gap between the ends of adjacent transverse ribs (including a longitudinal rib width) on both sides should not be greater than the sum of the nominal 20% reinforced perimeter. Ribbed steel usually with longitudinal ribs 9.5mm steel company, or without longitudinal ribs. Rebar Note: rebar generally bare strapping delivery, pay attention to moisture during storage 9.5mm steel, rebar corrosion performance of the adverse effects. Surface ribbed rebar steel, also known as ribbed steel bars, usually with two longitudinal ribs and evenly distributed along the length of the transverse ribs. Transverse rib shape helical, herringbone, crescent-shaped three kinds. With a nominal diameter of a few millimeters. Public ribbed steel equivalent to the cross section of the nominal diameter round bar etc. nominal diameter.
