The invention relates to the technical field of engineering machinery, in particular to a standard knot, a tower body and an assembling method of the standard knots of the tower body. The standard knot (1) comprises a plurality of web members (3) and a plurality of main chord members (2) vertically arranged, wherein the plurality of main chord members are distributed at intervals along a closed path, every two adjacent main chord members are detachably connected through the plurality of web members in the extension direction of the closed path, a mounting part (4) extending upwards is formed at the top end of each main chord member, a first mounting groove which is provided with a downward opening and can be matched with the corresponding mounting part is formed in the bottom end of each main chord member, a first mounting hole (21) and a second mounting hole (22) are formed in each first mounting groove, the central axes of the first mounting holes (21) and the second mounting holes (22) are distributed in different planes, and a third mounting hole matched with the corresponding first mounting hole and a fourth mounting hole matched with the corresponding second mounting hole areformed in the top of each mounting part. The plurality of main chord members and the plurality of web members are connected through adopting a detachable connecting mode, so that the disassembly andthe assembly are facilitated, and the range of the section specification of the standard knot is expanded.
本发明涉及工程机械技术领域,具体地涉及一种标准节、塔身和塔身的标准节的组装方法。所述标准节(1)包括多个腹杆(3)以及竖直设置的多个主弦杆(2),多个主弦杆沿闭合路径间隔分布,在闭合路径的延伸方向上,相邻两个主弦杆之间通过多个腹杆可拆卸地连接,每个主弦杆的顶端形成有向上延伸的安装部(4),每个主弦杆的底端形成有开口向下并且能够与安装部适配的第一安装槽,第一安装槽设置有中心轴线呈异面分布的第一安装孔(21)和第二安装孔(22),安装部的顶部设置有与第一安装孔配合的第三安装孔以及与第二安装孔配合的第四安装孔。通过采用可拆卸地连接的方式连接多个主弦杆和多个腹杆,便于拆装,扩大了标准节的截面规格的范围。
