Suspension bridge steel beam vertical splicing and vertical lifting in-air rotation erecting method
The invention relates to a suspension bridge steel beam vertical splicing and vertical lifting air rotation erecting method which comprises the following steps that a lifting platform is hung on two main cables on the side span side of a cable bent tower through temporary cable clamps, and four lifting cranes are installed on the lifting platform; the first steel beam section is conveyed to the position below the tower and vertically placed, and the first beam section is lifted through two cranes; the second beam section is conveyed to the position below the first beam section to be welded to the first beam section, and the multiple sections are welded into a large section through the same method; the large-section steel beam is vertically lifted, the four cranes are matched to turn the steel beam to the horizontal state in the air, and then the large-section steel beam is installed; and the temporary cable clamping frame is moved to suspend the lifting platform to the next position, and follow-up steel beams are sequentially installed through the same method. A support does not need to be erected, the construction cost is low, the speed is high, and safety is high.
本发明涉及一种悬索桥钢梁竖拼竖提空中转体架设方法，包括以下步骤：在索塔边跨侧两主索上采用临时索夹悬吊一起吊平台，起吊平台上安装4台提升吊机；将第一个钢梁节段运至塔下并竖向放置，用两台吊机提升第一个梁段；将第二个梁段运至第一个梁段下方与第一个梁段焊接，并用同样方法将多个节段焊接成大节段；竖向提升大节段钢梁，4台吊机配合将钢梁空中转体至水平状态，然后安装大节段钢梁；移动临时索夹架悬空起吊平台至下一位置，用同样方法依次安装后续钢梁。本发明不需要搭设支架，施工成本低，速度快，安全性高。
