Construction method for additionally building steel structure column on existing building concrete structure column
The invention discloses a construction method for additionally building a steel structure column on an existing building concrete structure column. A protective layer of a column head reinforcing steel bar of the existing concrete structure column is chiseled to expose the column head reinforcing steel bar; providing a plurality of core bars and a plurality of outer edge bars, and welding and connecting the plurality of core bars and the plurality of outer edge bars to the column head steel bar; a pre-embedded steel plate is provided, a plurality of penetrating holes are formed in the pre-embedded steel plate, and the positions of the penetrating holes correspond to the positions of the first vertical sections of the core ribs and the positions of the second vertical sections of the outer edge ribs one to one; the first vertical sections of the multiple core ribs and the second vertical sections of the multiple outer edge ribs are arranged in the penetrating holes of the embedded steel plate in a penetrating mode; the levelness of the embedded steel plate is adjusted, and the first vertical section and the second vertical section are connected to the embedded steel plate in a welded mode; grouting materials are poured between the embedded steel plate and the existing concrete structure column; and hoisting the steel structure column and mounting the steel structure column on the embedded steel plate. The problem that the construction efficiency is low when a steel structure column is additionally built on an existing building concrete structure column is solved.
本发明公开了一种既有建筑混凝土结构柱上加建钢结构柱的施工方法，将既有混凝土结构柱的柱头钢筋的保护层凿除以露出柱头钢筋；提供多根核心筋和多根外缘筋，将多根核心筋和多根外缘筋焊接连接于柱头钢筋；提供预埋钢板，于预埋钢板上开设多个穿孔，多个穿孔的位置分别与多根核心筋的第一竖直段和多根外缘筋的第二竖直段的位置一一对应；将多根核心筋的第一竖直段和多根外缘筋的第二竖直段分别穿设于预埋钢板的穿孔中；调整预埋钢板的水平度，并将第一竖直段、第二竖直段焊接连接于预埋钢板；于预埋钢板和既有混凝土结构柱之间灌注灌浆料；吊装钢结构柱并安装于预埋钢板上。本发明解决了既有建筑混凝土结构柱上加建钢结构柱存在施工效率低的问题。
