Construction method and structure for mechanical reinforcement of steel column foot anchor bolt
The invention discloses a construction method and structure for mechanical reinforcement of a steel column foot anchor bolt. The method comprises the steps that a mounting hole of a column foot bottom plate is subjected to reaming treatment; the anchor bolt is divided into an upper section and a lower section, the lower anchor bolt penetrates through the mounting hole of the column base bottom plate to be embedded into the concrete foundation, and the top of the lower anchor bolt is higher than the column base bottom plate; a steel base plate with a through hole is arranged above the column base bottom plate; a butt-joint nut is arranged between the upper anchor bolt and the lower bolt and penetrates through the through hole of the steel base plate, the lower end of the butt-joint nut enters the mounting hole of the column base bottom plate, the lower end of the upper anchor bolt is connected with the upper end of the lower anchor bolt through the butt-joint nut, and the upper end of the upper anchor bolt is higher than the steel base plate; and a nut is mounted at the upper end of the upper anchor bolt above the steel base plate. The anchor bolt is divided into two sections, the exposed length of the anchor bolt is prolonged in a sleeving reinforcement mode, and the problem that a nut cannot be installed due to the fact that the anchor bolt of the column foot joint is too short is solved.
本发明公开一种钢柱柱脚锚栓机械补强的施工工法及结构，方法包括：将柱脚底板的安装孔进行扩孔处理；将锚栓分为上下两段，下锚栓穿过柱脚底板的安装孔埋入混凝土基础，且下锚栓顶部高出柱脚底板；在柱脚底板上方设置带有通孔的钢垫板；在上锚栓与下螺栓之间设置对接螺帽，该对接螺帽穿过所述钢垫板的通孔，且对接螺帽下端进入所述柱脚底板的安装孔中，通过对接螺帽将上锚栓下端与下锚栓上端连接，上锚栓上端高出钢垫板；在钢垫板上方的上锚栓上端安装螺母。本发明通过将锚栓分为两段并通过套接补强方式延长其外露长度，解决了柱脚节点锚栓过短导致的无法安装螺母的问题。
