Purline with double-layer flanges and preparation method of purline
According to the purline with the double-layer flanges and the preparation method of the purline, the double-layer flanges are formed after the full flanges of the purline are folded, so that the plate stability of the pressed flanges is improved, the material strength utilization rate of the purline flanges and webs is improved, and the bearing capacity and economical efficiency of the purline are improved. The double-layer flanges comprise folding flanges and initial flanges, and the folding flanges are attached to the inner sides or the outer sides of the connected initial flanges; the fitting parts of the folding flanges and the web plates are fixedly connected through welding or riveting, so that the cooperative stress between the initial flanges and the folding flanges is realized, the overall structure is stable, the constraint effect of the web plates on the flanges is enhanced, local buckling and distorted buckling of the flanges are delayed, and the service life of the flanges is prolonged. The technical effect that the bearing capacity of the purline is improved by more than 15% under the same material consumption is achieved.
本发明提出一种双层翼缘的檩条及其制备方法，将檩条的全翼缘折叠后形成双层翼缘，来提高受压翼缘的板件稳定性，从而提高檩条翼缘和腹板的材料强度利用率，提高檩条的承载力和经济性。双层翼缘包括折叠翼缘和初始翼缘，折叠翼缘贴合于相连的初始翼缘的内侧或者外侧；在折叠翼缘和腹板的贴合部通过焊接或铆接固定连接，实现了初始翼缘和折叠翼缘之间的协同受力，整体结构稳固，增强了腹板对翼缘的约束效应，延缓翼缘的局部屈曲和畸变屈曲，实现相同材料用量下的檩条承载力提高15％以上的技术效果。
