The invention relates to a construction method for reinforcing a rectangular variable-cross-section frame column of a historical building. The construction method comprises the steps that lower-layerreinforcing angle steel wraps the four corners of a bottom-layer frame column; the lower-layer reinforcing angle steel is welded by flat steel batten plates; a lower angle steel enclosure is installedat a column foot of the bottom-layer frame column; the lower-layer reinforcing angle steel penetrates through an upper-layer floor; a second-layer lower angle steel enclosure is arranged at the edgeof the lower-layer reinforcing angle steel tightly attaching to and penetrating through the floor; upper-layer reinforcing angle steel is installed according to the steps 1 and 2, and a lower openingof the upper-layer reinforcing angle steel 11 is connected with the top end of the lower-layer reinforcing angle steel 1 through short angle steel 4; epoxy mortar is poured into a cavity formed by theupper-layer floor, the lower angle steel enclosure, the short angle steel, the upper-layer reinforcing angle steel and the lower-layer reinforcing angle steel; beam-penetrating reinforcing steel barsare embedded, and two ends of the beam-penetrating reinforcing steel bars are welded with the reinforcing angle steel; an upper angle steel enclosure is added at the position, located at the lower edge of a frame beam, of the periphery of the frame column; and epoxy mortar 8 is poured among all the reinforcing angle steel, the flat steel batten plates and an original reinforcing frame column. Themethod is a reinforcing measure which is a safe, effective and high-enforceability.
本发明涉及一种用于历史建筑矩形变截面框架柱加固的施工方法包括在底层框架柱四角采用下层加固角钢包裹；下层加固角钢之间采用扁钢缀板焊接；在底层框架柱柱脚安装下角钢围套；下层加固角钢穿过上层楼板；紧贴穿楼板的下层加固角钢边缘安装第二层下角钢围套；按步骤1、2安装上层加固角钢，上层加固角钢11下口与下层加固角钢1顶端通过短角钢4连接；在上层楼板、下角钢围套、短角钢、上层加固角钢、下层加固角钢形成的空腔处灌入环氧砂浆；埋设穿梁钢筋，穿梁钢筋两端与加固角钢焊接；在框架梁下沿处框架柱四周增加上角钢围套；所有加固角钢、扁钢缀板与原加固框架柱间采用环氧砂浆8灌注。本发明安全、有效、可实施性强的加固措施。
