工程建设监理工作中发现,有些施工人员在钢筋工程施工时,为保证柱或梁的钢筋骨架不变形、不错位或移位,常将骨架的部分箍筋与主筋点焊固定。这种施工方法在一定程度上确保了柱或梁的骨架截面尺寸,但却会对主筋产生极大的危害,易造成主筋脆断事故,而且点焊主筋的直径越大,这种危害也越明显。虽然这种作法在规范上尚无明文禁止,其实并不可取。
The supervision of engineering construction found that some construction workers often spot welded some of the stirrups to the main tendons in order to ensure that the columns or beams are not deformed, definite or displaced during the construction of steel bars. This construction method to a certain extent to ensure the column or beam skeleton cross-sectional size, but it will have a great danger to the main tendons, easily lead to the main tendons brittle fracture accident, and the greater the diameter of the spot welding main tendons, the more harmful this obvious. Although this practice has not been explicitly prohibited by the code, it is actually not desirable.
