Detachable n-shaped fixing device

A detachable n-shaped fixing device belongs to the technical field of welding, processing and manufacturing of ribbed sheets of boxboard steel structure residential building projects and comprises an n-shaped clip (1), a bolt (2), a nut (3) and angle steel (4). The n-shaped clamp (1) is in bolted connection with the angle steel (4) through the bolt (2) and the nut (3), the bolt (2) penetrates through a hole of the angle steel (4) and a hole of the n-shaped clamp (1), the nut (3) tightens the bolt (2), and the angle steel (4) is welded on the thin plate. The anti-deformation clamp has the advantages that the anti-deformation control is good, the one-time qualified quality of thin plate welding is greatly improved, and the processing period is further shortened. 一种可拆卸的几字型固定装置，属于箱板钢结构住宅楼项目带肋薄板焊接加工制作技术领域,包括"几"字型卡子(1)、螺栓(2)、螺母(3)、角钢(4)；"几"字型卡子(1)与角钢(4)通过螺栓(2)、螺母(3)栓接连接，螺栓(2)穿过角钢(4)的孔和"几"字型卡子(1)的孔，螺母(3)拧紧螺栓(2)，角钢(4)焊接在薄板上。优点在于，防变形控制好，大大提高了薄板焊接的一次合格的质量，进而缩短加工周期。
