一、冷轧扭钢筋混凝土应用技术是国家建设部和国家科委1996年科技成果重点推广项目,冷轧扭钢筋是低碳钢热轧圆盘条经专用钢筋冷轧扭机调直冷轧并冷扭一次成型,具有规定截面形状和节距的连续性螺旋状钢筋,冷轧扭钢筋是一种延性好,锚固性能优良的新型高效钢筋,代替Ⅰ级热轧圆钢用于现浇混凝土结构中,可以节约钢材30％左右,不仅可以提高构件质量,而且
1. The application technology of cold-rolled and twisted reinforced concrete is a key promotion project for scientific and technological achievements of the State Ministry of Construction and the State Science and Technology Commission in 1996. The cold-rolled and twisted steel bars are cold rolled and twisted by special steel cold-rolled twisting machines for cold rolled and twisted steel bars. Cold torsion one-time forming, continuous spiral steel bar with prescribed section shape and pitch, cold rolled and twisted steel bar is a new high-efficiency steel bar with good ductility and excellent anchorage performance, instead of I-level hot-rolled round steel used for cast-in-situ concrete structure In addition, about 30% of steel can be saved, not only improving the quality of components, but also
