Variable cross-section steel beam bidirectional incremental launching construction mechanism and construction method
The invention relates to the technical field of bridge construction, and discloses a variable cross-section steel beam bidirectional incremental launching construction mechanism and a construction method.The variable cross-section steel beam bidirectional incremental launching construction mechanism comprises an incremental launching platform located on a bridge side span; a plurality of walking type jacks are provided; the bridge steel beam is divided into a plurality of steel beam sections from the closure opening to the two ends of the bridge in the transverse bridge direction; the leveling brackets are installed at the bottom of the bridge steel beam, each leveling bracket is only connected with one steel beam section, and the leveling brackets and the bridge steel beam are combined to form a straight long-strip-shaped column. Due to the fact that the installation mode of successive splicing and successive pushing is adopted, even if deviation occurs in the installation process, the deviation can be found quickly and corrected in time. Meanwhile, the size of the component hoisted each time is much smaller than that of the component hoisted by an integral hoisting method in the prior art, the task can be completed by adopting a small crane, meanwhile, the influence of environmental factors such as wind power on the small component is small, and the whole installation process is safer. And the single-time pushing distance is small, so that control is easy, and the safety risk is low.
本发明涉及桥梁施工技术领域，公开了一种变截面钢梁双向顶推施工机构及施工方法，包括：顶推平台，位于桥梁边跨；步履式千斤顶，有多个；桥钢梁，其自合龙口沿横桥向桥梁两端划分为若干个钢梁节段；调平托架，有多组，均安装于桥钢梁底部，每个调平托架仅与一个钢梁节段相连，调平托架和桥钢梁组合形成平直的长条柱状。本发明由于采用逐次拼接、逐次顶推的安装方式，即使在安装过程中出现偏差，也可以很快发现并及时修正。同时每次吊装的部件体积相较于现有技术中整体吊装的方法小很多，可以采用小吊机就能完成任务，同时较小的部件受风力等环境因素的影响较小，整个安装过程更为安全。并且因为单次顶推的距离较小，易于控制，安全风险低。
