Method for erecting large road and bridge steel truss girder
The invention relates to an erecting method of a large road and bridge steel truss girder. The erecting method comprises the specific steps that S1, a splicing platform and a support are positioned and constructed; s2, mounting a slideway beam; s3, the steel truss girder is spliced and installed on site in a segmented mode; s4, dragging and sliding preparation; s5, a transverse movement power structure is installed; s6, pre-dragging the tractor; s7, the slide way beams and the assembly supports are dismantled; and S8, continuing to mount and erect the steel truss girder subsections. The method has the following advantages that the folding precision of each steel truss girder section is improved, and the erection construction time is shortened.
本发明涉及一种大型路桥钢桁梁的架设方法，具体步骤包括：S1、拼装平台以及支架定位施工；S2、滑道梁安装；S3、钢桁梁分段现场拼装安装；S4、拖拉滑动准备；S5、安装横移动力结构；S6、牵引器预拖拉；S7、拆除滑道梁以及拼装支架；S8、继续钢桁梁分段的安装架设。本发明具有如下优点：提高各个钢桁梁分段的合拢精度，缩短架设施工时间。
