复杂环境大挑臂盖梁型钢焊接托架全悬挑施工技术

Full Cantilever Construction Technology of Large Suspend Coping Steel Welding Bracket in Complex Environment

随着国内城市发展进程加速推进,乡镇土地绿色发展理念,更加深入人心,在桥梁工程设计方面,越来越重视桥梁下土地综合利用规划,大挑臂盖梁结构的使用逐渐广泛,常规采用满堂支架现浇、钢管支架现浇的施工方案,虽有悬挑,但宽度有限,在一些复杂环境下,要求悬挑宽度大幅增加,常规施工方案已无法满足现场施工需要,本文介绍一种型钢焊接托架全悬挑施工技术。

With the accelerated progress of domestic urban development, the concept of green development of township land has become more popular. In the design of bridge engineering, more and more attention is paid to comprehensive land use planning under bridges. The large suspend coping structures is gradually becoming more and more widely used. In conventional, the construction schemes of full frame cast-in-place and cast-in-situ steel pipe support are used. Although there are overhangs, the width is limited. In some complex environments, the overhang width is required to increase significantly. Conventional construction schemes cannot meet the needs of on-site construction. Fully cantilevered construction technology of steel welding bracket is introduced in this paper.
