The invention discloses a high and large assembly type cavity component hoisting method, and belongs to the technical field of component hoisting. Comprising the following steps that S1, a cavity component is horizontally placed on a platform; s2, the main lifting rope is tied to the top of the cavity component; s3, an E-shaped auxiliary clamp is installed on the top of the cavity component and tied to a crane main hook through a chain hoist; s4, the main hook is slowly lifted, so that the main lifting rope and a lifting chain of the hand-drive block are gradually tensioned until the main lifting rope and the lifting chain are tightened; s5, the length of a lifting chain of the chain hoist is adjusted, so that the tightening degree of the lifting chain is larger than that of the main lifting rope 2; and S6, hoisting. According to the invention, the stress problem of the double-leaf plate in the hoisting process of the high and large assembly type cavity component is solved, and the situation that the component is damaged due to tearing between the reinforcing steel bars in the cavity and the concrete is prevented; the problem that the perpendicularity cannot be guaranteed when the component is hoisted in place, and the connecting procedure between the hoisted component and the base body is affected is solved.
本发明公开了一种高大装配式空腔构件吊装方法,属于构件吊装技术领域;包括以下步骤:S1、将空腔构件平置于平台上;S2、将主吊绳系于空腔构件顶部;S3、在空腔构件的顶部安装E字型辅助卡具,并用手动葫芦系于吊车主钩上;S4、缓慢起升主钩,使主吊绳、手动葫芦的吊链逐步拉紧,直至绷紧;S5、调节手动葫芦的吊链长度,使吊链的绷紧程度大于主吊绳2的绷紧程度;S6、起吊。本发明,解决了高大装配式空腔构件在起吊过程中双叶板的受力问题,防止空腔内部钢筋与混凝凝土之间撕裂,造成构件本身破坏的情况;避免构件吊装就位时垂直度不能保障,影响吊装构件与基体之间的连接工序问题。
