[0041] Install the straight rod hanger, which consists of two parts: the base and the hanger. The base is fixed to the concrete beam by a hoop, and the straight rod hanger can be fixed in three directions. The hanger uses three 20 hemp ropes to pull the wind, and the other end of the hemp rope is fastened to the concrete column. A 1t chain hoist is hung on the upper end of the straight rod hanger as a hook.

[0042] Install the lower section of the column and the column base. The column is divided into 3 sections: the upper section, the middle section, and the lower end. The lower end of the lower section is connected to the base, and the upper end is connected to the middle section through a flange plate. The lower section of the column is hoisted into place using a straight rod hanger, and then the column base and the upper section of the column are connected by bolts and held on the concrete beam. Adjust the verticality of the lower section of the column and tighten the bolts.

[0043] Install the remaining bases, including the diagonal tie rod base and winch base. Each base is divided into 2 parts, which are connected by bolts to the concrete beam. Draw the position on the beam according to the size of the drawing and mark it. Place each base in the designated position. The base of the diagonal tie rod is temporarily connected with bolts and the connecting rod of the vertical pole base and the diagonal bar base is installed. Only the bolts are connected without tightening. Tighten and plug after the diagonal tie rod is installed.

[0044] Install the middle section and upper section of the column. The upper end of the upper section contains a guide pulley frame and a lightning rod, and the lower end is connected to the middle section through a flange plate. The two ends of the middle section are connected and fixed to the upper and lower sections respectively through flanges.

The lower pressure rod is lifted to the installation position by the hoist at the upper end of the straight rod hanger and connected to the connecting pin with the column.

[0051] Install the winch 6, which is fastened to the roof beam by a clamp. After the winch is debugged, the lifting wire rope is threaded and tested. After the wire rope comes out of the drum, it first passes over the guide pulley at the top of the column from the upper end, goes down to the pulley at the root of the upper pull rod, and finally connects and fixes to the hook head through the pulley at the head of the lower pressure rod. After threading the rope, power on and test run to check the operation of each mechanism and the stability of the structure. Install equipment grounding and lightning protection equipment. The lightning protection facility is connected to the roof grounding grid by bolts.
