Steel box girder hoisting process
The invention relates to a steel box girder hoisting technology which comprises the steps that a pier top cross beam of a steel box girder structure is divided into three sections in the width direction of a road, the two ends of the pier top cross beam are end sections, one section of the pier top cross beam is a middle section, and the middle section is located between the two end sections; the height of the temporary support of the pier top cross beam is higher than that of the pier, then the two end sections are hoisted through a truck crane, the end sections are placed at the upper ends of the temporary support of the pier top cross beam, then lifting equipment is installed on the upper surfaces of the end sections, and the lifting equipment is hoisted through the truck crane; and then the two ends of the middle section are lifted through lifting equipment on the two end sections at the same time, the middle section and the end sections are connected after the middle section reaches the position where the middle section is in butt joint with the end sections, and finally the temporary support of the pier top cross beam is dismantled so that the gravity of the pier top cross beam can be transferred to the pier. The hoisting device has the effect of facilitating hoisting of the steel box girder.
本申请涉及一种钢箱梁吊装工艺，其包括将钢箱梁结构的墩顶横梁沿道路的宽度方向分为三段，两端为端部节段，一段为中间节段，且中间节段位于两个端部节段之间，先在桥墩的位置搭设墩顶横梁的临时支撑，并且墩顶横梁的临时支撑的高度高于桥墩，然后通过汽车吊对两个端部节段进行吊装，使端部节段放置在墩顶横梁的临时支撑的上端，然后在端部节段的上表面安装提升设备，提升设备采用汽车吊进行吊装，再通过两个端部节段上的提升设备同时对中间节段的两端进行起吊，中间节段到达与端部节段对接的位置后连接中间节段和端部节段，最后拆除墩顶横梁的临时支撑使墩顶横梁的重力转移到桥墩上。本申请具有方便钢箱梁的吊装的效果。
