Device and method for detachable manual assembling steel column

The invention discloses a device and a method for a detachable manual assembling steel column, and relates to the field of building equipment. A technical scheme is that the device comprises a steel column base used to place a steel column and a support, and the middle part of the steel column is bound with one end of a sling. The sling crosses the top of the support. A free end of the sling is held by hand of a constructor. The steel column base is fixedly provided with a base. One end of the base, far away from the support, is hinged with one end of a connecting component. The other end of the connecting component is fixedly connected with the lower outer side of the steel column. An included angle between the side surface of steel column, facing the steel column, and a horizontal planeis larger than or equal to 30 DEG and is smaller than or equal to 90 DEG. Beneficial effects are that the structure connection form is used in the device, and the device is suitable for assembly of steel columns in different
