The invention provides a round tenon joint integrated main chord member and a tower crane standard knot, and the round tenon joint integrated main chord member comprises a main chord member main rod, and a female joint and a male joint which integrally axially extend outwards from the two ends of the main chord member main rod along the length direction of the main chord member main rod, a mortise hole is arranged in the female joint, a mortise plugging core rod for sealing one end of the main chord member main rod is fixed in the female joint, a tenon section is arranged on the male joint, and a tenon plugging core rod for sealing one end of the main chord member main rod is fixed in the tenon section; and the aperture of the mortise hole of the female joint and the outer diameter of the tenon section of the male joint are in clearance fit with the same nominal size. In the application, the joints of the female joint and the male joint with the main chord member main rod are free of welding joints, connecting sleeves, welding seams and welding stress, so that the safety and the reliability are higher. And meanwhile, two adjacent tower crane standard sections are convenient and labor-saving to mount and dismount, and the joint of each tower crane standard section does not need to be subjected to regular safety inspection during use.

    本发明提供一种园榫接头一体化主弦杆及塔式起重机标准节,园榫接头一体化主弦杆包括主弦杆主杆、以及沿主弦杆主杆的长度方向从主弦杆主杆两端一体地轴向外延的母接头和公接头,母接头内设置有榫眼孔、以及内部固定有密封主弦杆主杆一端的榫眼封堵芯棒,公接头设有一段榫头段、以及内部固定有密封主弦杆主杆一端的榫头封堵芯棒,母接头的榫眼孔的孔径与公接头的榫头段的外径之间为公称尺寸相同的间隙配合关系。本申请中,母接头和公接头与主弦杆主杆的连接处无焊接接头、连接套、焊缝和焊接应力,更加安全可靠。同时,使得相邻两节塔式起重机标准节的安装拆卸方便省力,使用时也无需对每个塔式起重机标准节的接头定期诸个安全检查。
