Span steel tube tower tubular joint
The invention discloses a span steel tube tower tubular joint. The span steel tube tower tubular joint comprises a joint core, wherein branch pipes are fixedly installed on the joint core, the branch pipes include a tower body main pipe connecting pipe, a cross arm main pipe connecting pipe, a tower body horizontal material connecting pipe, a tower body inclined material connecting pipe and a transverse separation face inclined material connecting pipe, and joint flanges and joint bolts are further installed on the branch pipes; the cast steel joint core and the branch pipes are integrally formed by adopting an integral pouring technique, and the joint core can be made to be solid or hollow as required; the joint flanges are welded to pipe openings of all the branch pipes of the joint, the branch pipes and the joint flanges are connected through annular T-joint welding seams, and stiffening plates are evenly arranged in the annular direction; and the branch pipes of the joint are connected with rod pieces in the corresponding direction of a span tower body through the joint flanges and the joint bolts. The joint structure and stress distribution are reasonable, the joint form is flexible, intersecting line cutting and a complex welding process are avoided, local residual stress generated by overlapped welding seams is eliminated, manufacturing and mounting are convenient and fast, and the joint structure can be popularized and applied to an ultrahigh-span steel tube tower of a power transmission line.
本发明公布了一种跨越钢管塔相贯节点，包括节点核心，所述节点核心上固定安装有支管，支管包括塔身主管连接管、横担主管连接管、塔身水平材连接管、塔身斜材连接管和横隔面斜材连接管，在各支管上还安装有接头法兰和接头螺栓。铸钢节点核心及各支管采用整体浇注技术一体成型，节点核心可根据需要做成实心或空心；节点各支管管口焊有接头法兰，支管与接头法兰采用环形T接焊缝连接，并设置沿环向均匀布置的加劲板；节点各支管通过接头法兰、接头螺栓与跨越塔身对应方位的杆件连接。节点构造、应力分布合理，节点形式灵活，避免相贯线切割和复杂的焊接工艺，消除重叠焊缝产生的局部残余应力，且制作安装方便快捷，可在输电线路超高跨越钢管塔中推广应用。
