Hoisting method of integral anti-collision wall side box girder
The invention discloses a hoisting method of an integral type anti-collision wall side box girder, which comprises the following steps of: S10, simulating a balance hoisting point which is overlapped with a vertical vertical line on which the gravity center is positioned according to the gravity center, finding out a symmetric point of one side of the side box girder, which is provided with an anti-collision wall, relative to one side without the anti-collision wall; simulating a connecting line between the symmetric point and the edge vertex of one side with the anti-collision wall, and extending the connecting line until the connecting line intersects with a vertical perpendicular line where the gravity center is located, wherein the intersection point is a balance lifting point; s20, a connecting rope is manufactured, and the length of the connecting rope is the sum of the connecting rope starting from the balance lifting point to the top point of the edge of the side without the anti-collision wall and the bottom of the surrounding edge box girder and returning to the balance lifting point from the top point of the edge of the side with the anti-collision wall; and S30, positioning parts are arranged at the edge points of the bottoms of the side box girders and the edge vertexes of the sides with the anti-collision walls, connecting ropes are wound around the peripheral sides of the bottoms of the side box girders through the positioning parts, and the two ends of the connecting ropes are connected to the balance lifting points. A series of safety problems caused by unequal tension distribution and gravity center deviation when irregular side box girders are hoisted are solved.
本发明公开了一种整体式防撞墙边箱梁的吊装方法，获取边箱梁重心，S10、根据重心模拟与重心所在竖向垂线的重合的平衡吊点，找出边箱梁具有防撞墙一侧相对于无防撞墙一侧的对称点，将对称点与具有防撞墙一侧的边缘顶点模拟连线并延伸连线至与重心所在竖向垂线相交，交点即为平衡吊点；S20、制作连接绳，连接绳的长度为从平衡吊点出发到无防撞墙一侧边缘顶点与包围边箱梁底部并从具有防撞墙一侧边缘顶点回到平衡吊点之和；S30、将边箱梁底部的边缘点以及具有防撞墙一侧的边缘顶点设置定位部，将连接绳通过定位部绕边箱梁的底部周侧，并将连接绳的两端连接于平衡吊点。以解决对于不规则的边箱梁吊装时分配拉力不等，重心偏离导致的一系列安全性问题。
