I-shaped steel beam rotating body hoisting method
The invention relates to the technical field of bridge construction, in particular to an I-shaped steel beam rotating body hoisting method. The method comprises the following steps: mounting a hoisting tool: arranging a lifting lug and a traction component on an I-shaped steel beam, mounting a hoisting rope on the lifting lug, and connecting the hoisting rope with a hoisting mechanism; hoisting the I-shaped steel beam: hoisting the I-shaped steel beam to a height exceeding the top of the pier through a hoisting mechanism, and maintaining the direction of the I-shaped steel beam through a traction component in the hoisting process; rotating the I-shaped steel beam: horizontally rotating the I-shaped steel beam by 90 degrees through a traction component; and mounting the I-shaped steel beam: hoisting the I-shaped steel beam to the installation position through a hoisting mechanism, and lowering the I-shaped steel beam to the top of the pier. The I-shaped steel beam is hoisted in a direction transverse to the bridge, constructors pull the I-shaped steel beam to rotate to a direction longitudinal to the bridge through the traction component, operation is completely conducted on the ground, convenience is achieved, safety is high, assembling construction, hoisting construction and pier construction of the I-shaped steel beam do not interfere with one another and can be conducted at the same time, and construction efficiency is improved.
本发明涉及桥梁施工技术领域，具体涉及一种工型钢梁转体吊装方法，包括如下步骤：安装吊具：在工型钢梁上设置吊耳和牵引部件，在吊耳上安装吊绳，吊绳与起重机构连接；起吊工型钢梁：通过起重机构将工型钢梁起升至超过桥墩顶部的高度，起升过程中通过牵引部件维持工型钢梁方向；转动工型钢梁：通过牵引部件水平转动工型钢梁90°；安装工型钢梁：通过起重机构吊装工型钢梁到安装位置，将工型钢梁下放至桥墩顶部。工型钢梁横桥向起吊，施工人员通过牵引部件拉动工型钢梁转动到顺桥向，完全在地面上进行操作，不仅方便，而且安全性高，工型钢梁的组拼施工和吊装施工，与桥墩的施工互相不发生干涉，可以同时进行，提高了施工效率。
