The invention discloses a large-size prefabricated segment vertical lifting appliance and a lifting method thereof, and aims to effectively solve the problems of low lifting appliance safety coefficient and difficulty in prefabricated segment lifting in the conventional lifting of prefabricated segments by using a lifting belt by using a specially-made vertical lifting appliance to lift the prefabricated segments. Three core rods are inserted into reserved holes of the hanging bracket and the prefabricated pipe piece from the lower portion and the top of the side face respectively, the two core rods on the lower portion of the side face can support the prefabricated pipe piece in the hoisting process, and the core rod on the top guarantees that the prefabricated pipe piece keeps balance in the hoisting process so as to prevent the prefabricated pipe piece from overturning. And smooth hoisting of the prefabricated duct piece is ensured.
本发明公开了一种大体积预制管片垂直吊具及其吊装方法,通过利用特制的垂直吊具来起吊预制管片,有效地解决了传统采用吊带吊运预制管片所面临的吊具安全系数低、预制管片吊装困难的问题,且在起吊预制管片时,通过从侧面下部和顶部分别向吊架和预制管片的预留孔洞内插入三根芯棒,侧面下部的两根芯棒可以对起吊过程中的预制管片进行支撑,顶部的芯棒在起吊过程中保证预制管片保持平衡以防止预制管片产生倾覆,保证预制管片吊装顺利进行。
