高强度φ9.00mm螺旋肋预应力钢丝的研制

Development of High Strength ?9.00 mm Spiral Ribbed PC Steel Wires

阐述了高强度Φ9.00mm螺旋肋预应力钢丝的生产工艺、力学性能和科学的几何外形。生产该钢丝所用原料是77B-1或S82BΦ13.00高线盘条。该钢丝用于建筑构件,可替代热轧带肋钢筋和冷轧带肋钢筋,简化构件生产工艺,节约钢材,降低构件成本,改善建筑结构,增大建筑物有效空间。

The process, mechanics property and reasonable geometry of high strength φ9.00 mm spiral ribbed PC steel wire are expounded. 77B - 1 or S82B φ13.00 mm high ?speed wire rods are raw material for producing the steel wires. Substitution of the wire for hot - rolled and cold - rolled ribbed reinforcing bar in building structure framing. It can simplify the process of structure framing, save steel, reduce cost, improve building structure and enlarge effective space of buildings.
