The invention relates to a foldable tower crane standard knot, belongs to the technical field of building construction, and aims to solve the technical problems that a welded standard knot is difficult to disassemble and occupies a large transportation and placement space, and adopts the technical scheme that the foldable tower crane standard knot comprises two groups of sheet-shaped tower body sections which are oppositely arranged, each group of tower body sections comprises two main chord members and a plurality of first diagonal web members fixed between the main chord members, and every two adjacent first diagonal web members are arranged in a V shape; m second diagonal web members are arranged between the two groups of tower body sections, M is an integral multiple of 4, every two adjacent second diagonal web members are arranged in a V shape, one end of each second diagonal web member is rotatably connected with one group of tower body sections, and the other end of each second diagonal web member is detachably connected with the other group of tower body sections. The two tower body section components are connected through the second diagonal web members, when disassembly transportation or storage is needed, one ends of the second diagonal web members are disassembled, then the two tower body section components can be stacked, and the storage or transportation space is saved.

    本发明涉及可折叠的塔吊标准节,属于建筑施工技术领域,所要解决的是焊接标准节难以拆卸,会占用较多的运输和放置空间的技术问题,采用的技术方案为:可折叠的塔吊标准节,包括两组相对设置的片状塔身节,每组塔身节包括两根主弦杆、若干根固定于主弦杆之间的第一斜腹杆,相邻的两根第一斜腹杆成V形设置;两组塔身节之间M个第二斜腹杆,M为4的整数倍,相邻的两个第二斜腹杆成V形设置,第二斜腹杆的一端与一组塔身节转动连接,另一端与另一组塔身节可拆卸连接。本发明两个塔身节部件之间通过第二斜腹杆进行连接,当需要拆卸运输或是存放时,将第二斜腹杆的一端拆卸后,便可以将两个塔身节部件堆叠放置,节省存放或运输空间。
