The invention discloses web plate plum blossom hole opening profiled channel steel and a manufacturing method. The web plate plum blossom hole opening profiled channel steel comprises channel steel, wherein a plurality of plum blossom holes are formed in a web plate of the channel steel; the plurality of plum blossom holes are formed in the length direction of the channel steel at equal intervals;and folded edges are arranged on the edges of the peripheries of the plum blossom holes, and the folded edges are located on the inner side or the outer side of the web plate. Concrete is poured in the channel steel and on the outer surface of the channel steel, and the folded edges stretch into the concrete. According to the web plate plum blossom hole profiled channel steel, the web plate plumblossom folded edges of the channel steel structure are not disconnected with the original web plate, split hole opening reinforcement is naturally formed, the plum blossom holes enable the concrete to naturally flow through prefabricated or cast-in-place concrete, the connectivity and the integrity of the concrete are guaranteed, the channel steel web plate plum blossom folded edges serve as studs, so that the combined acting force of the steel concrete is better met, and the strength of a prefabricated or cast-in-place component is improved. In addition, the plum blossom holes can meet the requirements of threading and pipe penetrating of the prefabricated or cast-in-place steel concrete component.
本发明公开了一种腹板梅花开孔压型槽钢及制造方法，一种腹板梅花开孔压型槽钢，包括槽钢，槽钢的腹板上开设有若干梅花孔，若干梅花孔沿槽钢的长度方向等间距布置，梅花孔的四周边缘均设置有折边，折边位于腹板的内侧或外侧。所述槽钢内以及外表面浇筑有混凝土，折边伸入混凝土内。本发明的槽钢结构的腹板梅花卷折边未与原腹板断开，自然形成对开孔口补强，梅花开孔在预制或现浇混凝土能让混凝土自然流过，保证混凝土的贯通性和整体性，槽型钢腹板梅花卷折边充当栓钉作用，更好的满足钢混凝土的共同作用力，提高了预制或现浇构件的强度。此外，梅花开孔还可以满足预制或现浇钢混凝土构件穿线、穿管的需求。
