The invention discloses a hoisting rod piece for a caisson and a manufacturing method of the hoisting rod piece.The side wall of the rod body of the caisson hoisting rod piece is rolled with a protruding part for increasing the bond stress between the rod body and concrete, upward load during hoisting is uniformly transmitted to an external caisson or a large-scale concrete structural member, and meanwhile, the end part of the rod body is provided with a rod head with a through hole. And the hoisting rod piece can be connected with various hoisting tools through a pin shaft, is convenient and reliable, adopts an integrally forged structure, is safe and reliable, and can bear larger load after thermal refining.
本发明公开了沉箱用吊装杆件及其制作方法,沉箱用吊装杆件的杆体在侧壁滚压有突出部用以增加杆体与混凝土之间握裹力,将吊装时向上的载荷均匀的传递给外部沉箱或是大型混凝土结构件,同时,杆体的端部有带有通孔的杆头,通过销轴可以与多种起重吊装工具连接,方便可靠,整体锻造结构,安全可靠,经过调质处理可承受更大的载荷。
