二面肋冷轧带肋钢筋粘结性能研究

Research on Cohesive Force between Concrete and Cold rolled Dual Ribbed Steel Wires

研究二面肋冷轧带肋钢筋与混凝土的粘结应力 ,并与三面肋冷轧带肋钢筋及冷拔光面钢丝粘结应力的大小进行比较。结果表明 ,二面肋冷轧带肋钢筋的平均粘结应力等同或略高于三面肋冷轧带肋钢筋的平均粘结应力 ,明显高于冷拔光面钢丝的平均粘结应力 。

The cohesive stress between cold rolled dual ribbed steel wires and concrete is investigated and compared with the cohesive stress of cold rolled three faces ribbed steel wire and ordinary cold drawn steel wires The results show that the average cohesive stress between concrete and cold rolled dual ribbed steel wires is equal or higher than average cohesive stress of cold rolled three faces ribbed steel wires and obviously higher than average cohesive stress of ordinary cold drawn steel wires The cold rolled dual ribbed steel wires is also an excellent building material
