What are the installation and maintenance technologies for communication towers
The installation and path of the outdoor cable frame climbing ladder of the communication tower must be installed in accordance with the requirements of the drawing. If there is no requirement in the drawing or if it is difficult to install according to the requirements of the drawing, a reasonable path should be selected, and the designer and the project management personnel of the construction unit must be communicated and agreed. It can be installed later, and the changed drawings must be reflected on the construction plan to facilitate the design change drawings.
The cable rack is directly connected from the cable tower to the cable inlet of the machine room. Use 4 expansion bolts to install a piece of ∠5～∠7 fixed iron with the same width as the cable rack 20cm below the cable inlet. A fixed iron is also installed on the cable tower, (make the cable rack low on the tower side and high on the computer room side to prevent rainwater from entering the computer room). The cable rack is mounted on the fixed iron at both ends. If it is a support frame for the color steel computer room Hold the cable rack, if the cable rack is longer than 3 meters, install a support frame every 3 meters; the communication tower cable rack should be welded to the feeder lightning protection belt, and the welding point must be above the cable rack, on the roof of the building. If there are grounding steel bars, the two ends of the cable rack must be welded to the grounding grid, and the cable rack shall be welded to the grounding grid every 12 meters; the cable rack should be turned as little as possible, and the turning angle shall not be less than 90°. After finishing, check and tighten each bolt.
