The invention belongs to the technical field of tower crane attachment frames, and particularly relates to a large standard knot attachment frame and a square installation method.The attachment frame comprises a left half frame, a right half frame, hoops and connecting beams, the two ends of the left half frame and the two ends of the right half frame are connected into the complete attachment frame through the connecting beams, the hoops are hinged to the corners of the half frames, and the hoops and the half frames form an integrated structure; and brackets for fixing the pin shafts are arranged on the left half frame and the right half frame. The mounting method comprises the following steps: sequentially hoisting the left and right half frames on the standard knot main chord; hoisting connecting beams at two ends of the left and right half frames; and the opening end of the hoop is hinged with the left half frame and the right half frame through a pin shaft and is tightly held on the standard knot main chord. The attachment half frames and the hoops are integrally installed, meanwhile, the pin shaft brackets are arranged on the attachment frames, the hoops and the pin shafts can be hoisted along with the attachment frames at the same time, the hoisting frequency is greatly reduced, and the installation efficiency of the attachment frames is improved. Meanwhile, a wedge-caulking device is arranged on the hoop, so that the situation that the main chord and the hoop cannot be tightly wedged due to manufacturing errors, and the use safety is affected is avoided.

    本发明属于塔机附着框技术领域,具体为一种大型标准节附着框及方安装方法,附着框包括左半框、右半框、抱箍和连接梁,左半框、右半框两端通过连接梁连接成完整的附着框,半框的拐角处铰接抱箍,抱箍与半框形成一体结构;左半框、右半框上设置有固定销轴的托架。安装方法,先后吊装左右半框安装在标准节主弦;然后吊装连接梁安装在左右半框两端;再将抱箍的开口端通过销轴与左、半框铰接,抱紧在标准节主弦上。本发明将附着半框和抱箍集成化安装,同时在附着框设置销轴托架,抱箍、销轴可随附着框同时吊装,大大减少了吊装次数,提高了附着框的安装效率。同时在抱箍设置楔紧装置,避免因制造误差导致主弦与抱箍之间无法楔紧,影响使用安全性。
