The invention discloses a construction tool for plug-in steel column installation. The construction tool for plug-in steel column installation comprises a positioning device and a nut locking device,the positioning device comprises a positioning sleeve and a positioning rod, one end of the positioning sleeve is provided with a sleeve opening, the other end of the positioning sleeve is connected with the positioning rod, the positioning sleeve and the positioning rod are located on the same axis, and the sleeve can be sleeved on a foundation anchor bolt through the sleeve opening; and the nutlocking device comprises a nut locking sleeve, a stress application rod and a torque wrench, one end of the stress application rod is connected with the nut locking sleeve, the other end of the stressapplication rod is connected with the torque wrench, and the length of the stress application rod is not smaller than the pit depth of a foundation pit. Working personnel do not need to enter the foundation pit, downward inserting installation of a steel column can be completed only outside the foundation pit, the installation efficiency of the steel column is greatly improved, and meanwhile thesituation that in the process that the personnel go down to the foundation pit to install the steel column, the steel column shakes, and consequently the personnel are injured is avoided.

本发明公开了一种插入式钢柱安装的施工工具，包括：定位装置，包括定位套筒和定位杆，所述套筒的一端设有套口，另一端与所述定位杆连接，所述定位套筒和所述定位杆在同一轴线上，所述套筒可通过所述套口套装在地脚锚栓上；螺母锁紧装置，包括螺母锁紧套筒、加力杆和扭力扳手，所述加力杆的一端与所述螺母锁紧套筒连接，另一端与所述扭力扳手连接，所述加力杆的长度不低于基坑的坑深。工作人员不需要进入基坑内，只需要在坑外就可以完成钢柱的下插安装，极大的提高了钢柱的安装效率，同时也避免了人员下到基坑进行钢柱安装的过程中，钢柱晃动造成人员受伤等情况。
