Steel column jacking construction method
The invention relates to a steel column jacking construction method which comprises the following steps: welding reverse jacking section steel on two sides of an original column web, and jacking the reverse jacking section steel by adopting a jack; the first flange plate is disconnected in the horizontal direction, a flange reinforcing steel plate is installed on the outer side of the first flange plate, and a limiting steel plate is welded to the flange reinforcing steel plate; the second flange plate is disconnected in the horizontal direction, a flange reinforcing steel plate is installed on the outer side of the second flange plate, and a limiting steel plate is welded to the flange reinforcing steel plate; breaking the original column web along the horizontal direction, and mounting web reinforcing steel plates on two sides of the original column web; the prototype steel column is jacked, the upper portions of the two flange reinforcing steel plates are welded, and flange connecting steel plates are installed; mounting a web connecting steel plate; welding the upper part of the web reinforcing steel plate to the web; and S7, the limiting steel plate is dismantled. The construction method can be used for reinforcing and jacking the supporting steel column, the process is simple, operation is convenient, the construction efficiency is high, the construction period is short, and the construction safety and the construction quality can be effectively guaranteed.
本发明涉及一种钢柱顶升施工方法，包括如下步骤：在原柱腹板的两侧焊接反顶型钢，采用千斤顶顶实反顶型钢；沿水平方向断开第一翼缘板，在第一翼缘板的外侧安装翼缘加强钢板，将限位钢板焊接于翼缘加强钢板；沿水平方向断开第二翼缘板，在第二翼缘板的外侧安装翼缘加强钢板，将限位钢板焊接于翼缘加强钢板；沿水平方向断开原柱腹板，在原柱腹板的两侧安装腹板加强钢板；将原型钢柱顶升，焊接两个翼缘加强钢板的上部，安装翼缘连接钢板；安装腹板连接钢板；将腹板加强钢板的上部焊接于腹板；S7、拆除限位钢板。所述施工方法可用于对支撑钢柱进行加固顶升，其工序简单，便于操作，施工效率高、工期短，可有效保障施工安全性和施工质量。
