[0009] Furthermore, the plug-in column is a lattice column.

[0010] Furthermore, the suspension rods are respectively installed on the four sides of the plug-in column.

[0011] Furthermore, the telescopic assembly includes:

[0012] A screw rod, wherein a through hole is formed on the second connecting plate of the plug-in column, and the screw rod can be movably inserted into the shaft hole;

[0013] Two screw-on parts, the two screw-on parts are screwed on the screw rod, and the two screw-on parts are clamped on the second fixing plate.

[0014] Furthermore, the lifting ears are respectively provided on opposite sides of the upper end of the plug-in column.

[0015] Furthermore, the hook is U-shaped.

[0016] The present invention provides a construction method of a steel lattice column installation auxiliary device, comprising the following steps:

[0017] The lower end of the plug-in column is detachably inserted into the upper end of the steel lattice column;

[0018] Contracting the telescopic assembly to allow the first tie plate on one side of the steel lattice column to be hung on the hook at the lower end of the suspension rod;
