摘要
大规格螺纹钢筋(φ32～φ40mm)能满足大型、高层建筑使用,本文论述其冷、反弯检验中裂纹产生的原因,分析改善大规格螺纹钢筋工艺性能。
Large sized (φ32-φ40mm)deformed steel bars are fit for big and high storey buildings. In this paper causes of cracking happened in these bars during cold bend and reverse bend tests are found. Measures of improving technological performances and shortening the store time have been suggested and relevant tests have also been described.
