The invention relates to a core reserving and replacement reinforcing construction method for a concrete frame column which comprises the following steps: detecting the frame column to determine a to-be-chiseled area and a column core reserved area; erecting temporary supports around the frame column for unloading; dividing the to-be-chiseled area into an H shape along the cross section, wherein the area corresponding to the concave part of the H-shaped cross section is a first to-be-chiseled area, and the area corresponding to the two side parts of the H-shaped cross section is a second to-be-chiseled area; chiseling off the first to-be-chiseled area; erecting a first formwork for the first to-be-chiseled area; pouring concrete or a grouting material into the first to-be-chiseled area; removing the first formwork; chiseling off the second to-be-chiseled area; erecting a second formwork for the second to-be-chiseled area; pouring concrete or a grouting material into the second to-be-chiseled area; removing the second formwork; and unloading in stages and removing the temporary supports. The construction method is safe, reliable and high in practicability, and the stability of a temporary supporting system and an original structure system in the construction process is improved.
本发明涉及一种混凝土框架柱留芯置换加固的施工方法，对框架柱进行检测，确定凿除区域和柱芯保留区域；在框架柱四周搭设临时支撑进行卸载；沿横断面将凿除区域划分成H型，H型横断面内凹部位对应的区域为第一凿除区域、H型横断面两侧部位对应的区域为第二凿除区域；对第一凿除区域进行凿除；对第一凿除区域搭设第一模板；在第一凿除区域内浇筑混凝土或灌浆料；对第一模板进行拆除；对第二凿除区域进行凿除；对第二凿除区域搭设第二模板；在第二凿除区域内浇筑混凝土或灌浆料；对第二模板进行拆除；对临时支撑进行分级卸载并拆除。本发明提供了一种安全可靠、可实施性强的施工方法，提高施工过程中临时支撑系统和原结构体系的稳定性。
