Steel truss girder construction system and construction method
The invention relates to a steel truss girder construction system and a construction method, the segmentation part of a steel truss girder is determined through computational simulation analysis, the steel truss girder is divided into a plurality of steel truss girder segments, the steel truss girder segments are spliced by using an adjustable splicing jig frame, and the overall deflection and the splicing precision of a truss can be well controlled; the installation technology that a temporary support is used for temporary supporting and in-air bulk combination is adopted, segmented hoisting is conducted through a truck crane, and the temporary support is manufactured at the cantilever end of a steel truss girder main beam segment and used for temporarily fixing the free end of the steel truss girder main beam segment and assisting the steel truss girder main beam segment in high-air bulk combination butt joint and welding; according to the welding slag collecting device and the safe operation platform, the heights of the collecting box and the lifting protective barrier can be adjusted according to the height and the position of a constructor, welding slag is collected as much as possible, splashing of the welding slag is prevented, and the safety protection effect on site constructors is improved.
本发明涉及一种钢桁架梁施工体系及施工方法，通过计算模拟分析确定钢桁架主梁的分段部位，将钢桁架主梁分为数段钢桁架主梁节段，并利用可调式拼接胎架对钢桁架主梁节段进行拼装，可以控制好桁架整体的挠度及拼装精度；采用临时支架进行临时支撑和空中散装结合的安装技术，利用汽车吊进行分段吊装，在钢桁梁主梁节段的悬挑端制作临时支架，用于临时固定其自由端，辅助钢桁架梁主梁节段在高空进行散装结合对接并焊接；焊渣收集装置和安全操作平台，可以根据施工人员的身高和位置调整收集箱与升降防护栏杆的高度，尽可能多地收集焊渣，防止焊渣飞溅，提高对现场施工人员的安全防护效果。
