Reputation rooted in a quality win, the preparatory work before a single column ad tower installation, if installation requires lane and hoisting advertising facilities in advance to the authorities run the relevant permit procedures; on-site assembly and lifting process can be broken lawn and trees, relevant Highways Department shall submit an application; when the lane, to establish warning signs at both ends of the occupation of the road, and sent someone to look after. 2, familiar with the drawings, organize relevant technical staff to analyze drawings of steel structures, construction technology and work together to arrange the construction plan. 3, the size of the installation of billboards select the appropriate crane and sling based on, snap ring, wind cable rope. Second, single-column ad tower Installation Notes 1, clear installation sequence: column → billboard skeleton hoisting installation → billboard sign face installation → sporadic components are installed. 2, basic review: Before installing arrange technical personnel to review the basis for measurement, inspection includes: basal plane to be smooth, can not have cracks, honeycomb, exposed tendons and so on; transverse centerline basic and perpendicular to the longitudinal centerline; foundation Dimensions deviation is less than 20mm. 3, install the mounting position to choose the right car to the geological conditions of stability and not to harm the green criteria; lifting height is not too high or too low, to lifting height of firmware and installation requires appropriate adjustments; adjust the verticality of the column with a cable wind rope eliminate personnel near adjustments to security risks; theodolite verticality verify that the installation is less than 10mm. 4, installation of billboards in addition to pay attention to the sign face lifting process of security issues, but also pay attention to anti-corrosion work welding firm, as well as the junction; lifting the promotion process should adjust billboard skeleton is inclined, and constantly adjust until to a safe location so far, the whole process by hand command, and with a whistle harmonized operational. 5, according to plans the lighthouse and other components installed. Third, the single-column ad tower construction safety requirements 1, aerial work seatbelt. 2, the lifting process, below the hanging objects can not stand people. 3, various materials stacked securely to prevent pitch and roll. 4, the high-altitude gas cutting or welding, should take measures to prevent cut metal or sparks falling wounding. 5, rain, wind greater than 4, such as at night, try to avoid high-altitude operations. 6, anti-corrosion coating construction site, should be avoided and inflammable and explosive materials put together, should be kept far distance between the two
