The top of the base is a frame body, and the four corners of the frame body are composed of vertical column connections. The tops of the four vertical columns are connected to the upper layer of vertical columns through the vertical column flanges to extend to the higher layer; the expansion screws fix the escalator to the escalator On the base, the side of the escalator is connected to the column by a connecting piece, the top of the escalator and the column is a square platform, the four sides of the top of the square platform are welded with a fence, the fence is covered with a layer of protective net, and the middle of the top of the square platform is the observation room. The observation room is a steel structure hut, with four walls on the side, close to the roof and above the fence are connected with reinforced steel beams to increase the strength of the observation room, the top of the observation room is the tapered roof, the four sides of the tapered roof A steel purlin is connected to the upper part, and steel beams are fixed on the four sides. The steel purlin and the steel beam are fixed together by bolts.

The base is distributed at four corners, and there are four embedded in the base of the watchtower
"L" type screw, two expansion screws are embedded in the base of the escalator;
Watchtower
The top of the base is a frame body, and the four corners of the frame body are composed of column connections. The two ends of the column are column flanges. The column flanges at the bottom of the column are fixed by bolts and "L" -shaped screws. The top sides of the four columns are on the same horizontal surface. Each adjacent two vertical column flanges are connected by horizontal steel beams. The bottom of the four horizontal steel beams is connected to the vertical columns on both sides by two reinforcing rods. The tops of the four vertical columns are connected by vertical flanges and The upper level column is connected to extend to the higher level; the expansion screw fixes the escalator to the escalator base, the side of the escalator is connected to the column through the connecting piece, the bottom of the escalator is fixed by the escalator bottom rod and the column, the escalator The top of the vertical column is a square platform. The four sides of the top of the square platform are welded with a fence, and the fence is covered with a protective net. The escalator extends into the fence. The middle of the top of the square platform is the observation room. The observation room is a steel structure. The hut, on a square platform, is equipped with air conditioning on the outer wall of the observation room, the door and window are installed on the wall near the side of the escalator, and the four walls of the observation room are close to Reinforced steel beams are connected to the roof and above the fence, respectively, and vertical rods are installed between the door frame and the window to increase the strength of the observation room. The top of the observation room is the tapered roof, and the four sides of the tapered roof are connected Steel purlins are fixed with steel beams on four sides. The steel purlins and steel beams are fixed together by bolts. Lightning rods are fixed on the eaves of the observation room and lighting lamps are fixed under the eaves.
