Walking type incremental launching construction method for variable-height steel beam
The invention discloses a walking type incremental launching construction method for a variable-height steel beam. The height and the line shape of the beam bottom are changed by installing detachable cushion blocks at the beam bottom, so that the beam bottom is changed from a large-gradient fold line to a horizontal line; the height of the temporary pier support is changed by installing a detachable short column on the temporary pier support; therefore, the walking type jack always vertically acts on the bottom of the steel beam, and the pushing action is smoothly implemented. The height of the section of the variable-height steel beam is greatly linearly changed within a short distance, the line shape of the beam bottom is a fold line with a large gradient, and when walking type pushing construction is adopted, the acting force direction of a walking type jack must be perpendicular to the beam bottom, so that the walking type jack cannot directly push the variable-height steel beam with the beam bottom being the fold line with the large gradient. The method provided by the invention solves the problem that the neck is blocked when the variable-height steel beam is constructed by adopting a walking type pushing method. The method provided by the invention solves the problem that the neck is blocked when the variable-height steel beam is constructed by adopting a walking type pushing method. Operation is easy, popularization is easy, and the construction speed is high; materials of the cushion blocks and the temporary support can be recycled, and the construction cost is low.
本发明公开了一种变高钢梁步履式顶推施工方法；通过在梁底安装可拆卸的垫块来改变梁底高度和线形，使梁底由大坡度折线为水平线；通过在临时墩支架上安装可拆卸短柱来改变临时墩支架高度；使得步履式千斤顶始终垂直作用于钢梁底，顺利实施顶推动作。变高钢梁截面高度在短距离内发生较大的线性变化，梁底线形为坡度较大的折线，采用步履式顶推施工时，由于步履式千斤顶作用力方向必须与梁底垂直，因此，步履式千斤顶无法直接顶推这类梁底为大坡度折线的变高钢梁。本专利所提出的方法解决了变高钢梁采用步履式顶推方法施工的卡脖子难题。本专利所提出的方法解决了变高钢梁采用步履式顶推方法施工的卡脖子难题。操作简单，易于推广，施工速度快；垫块、临时支架材料可重复利用，施工成本低。
