应用冷拔多头螺纹钢筋混凝土板的开裂问题初探

Preliminary Study of the Reinforced Cold-drawn Multiple Thread Steel Concrete Slab Fissility

应用冷拔多头螺纹钢筋的混凝土板开裂问题与应用普通钢筋的混凝土板开裂问题有很多相同的原因,但也有其突出的地方是值得我们注意的,本文从冷拔多头螺纹钢筋在实际应用中出现的一些问题出发,通过实验分析,提出现场施工中预防和克服混凝土板开裂的几种措施。

There are many similar reasons between using the cold - drawn multiple thread steel bar and ordinary steel bar. But it has its own prominent place which we should pay attention to. This paper is based on the problems in the application of the cold - drawn multiple thread steel bar. Through the analysis of experiments, the paper proposes several measures on bow to prevent and overcome concrete slab dehiscence.
