《钢筋焊接及验收规程》(JGJ 18-96)中对搭接焊接头处的轴线偏移和弯折角偏差给出了允许值,但未给出接头的预弯角度。笔者针对许多施工企业在接头处轴线及弯折角控制较差的现实,谈谈自己的经验。搭接焊的轴线和弯折角控制得好坏,预弯角度起了决定性的作用,预弯角度不正
The allowable values for the axis offset and bend angle at the lap weld joint are given in the Rules for Welding and Acceptance of Reinforced Bar Steel (JGJ 18-96), but the pre-bend angle of the joint is not given. The author for many construction companies in the joint axis and bending angle of the reality of poor control, to talk about their own experience. Lap welding axis and bending angle control is good or bad, pre-bending angle played a decisive role, pre-bending angle is not correct
