焊接时应加角铁作垫板模。

剧增第7章焊接安好。

预埋件钢筋电弧焊T形接头可分为角焊和穿孔塞焊两种(图4.5.10),配和焊接时,应吻合下列渴求:1当采用HBB235、HPB300钢筋时,角焊缝焊足尺码(k)不可小于钢筋直径的0.5倍;采用其它牌号钢筋时,焊足尺码(k)不可小于钢筋直径的0.6倍;2施焊中,不可使钢筋咬边和灼伤。

总则,2,术语和记号。

应精心将下料钢筋按设计图纸规程尺码曲折成形,制成待焊箍筋,并使两个对焊头完整针对,具有特定弹性压力,见图4.4.3图4.4.3待焊箍筋ag-箍筋内净长度;b-g箍筋内净宽窄;55、-焊接总留量;Ft-弹性压力Ft弹性压力4.4.4待焊箍筋应进展加工质量的检讨,按每一职业班、同一牌号钢筋、同一加工设备完竣的待焊箍筋当做一个检验批,每批抽查不少于3件。

本规程第1版于1965年照准宣布以来,随着钢筋焊接技能的不止发展,经84版、96版、2003版,于今已是四次审订。

注:当试件外侧横向裂纹宽窄达成0.5mm时,应认可曾经分裂。

钢筋电渣压力焊electroslagpressureweldingofreinforcingsteelbar将两钢筋安放成竖向对接式,采用焊接电流经过两钢筋端平面间隙,在焊剂层下形成电弧进程和电渣进程,发生电弧热乎电阻热,熔钢筋,加压完竣的一样压焊法子。
