Description

Technical Field

[0001] The invention belongs to the technical field of steel structure installation facilities, and in particular relates to a steel cable slide rail type access platform for steel structure installation. Background Art

[0002] With the development of social economy and the popularization of prefabricated buildings, steel structures are widely used in urban housing construction projects due to their own advantages. During the construction of the steel structure, due to the influence of the structural form, it is difficult to build a construction platform. Construction workers need to stand on the steel structure and tie a safety rope around their bodies to perform construction work during the process of tightening steel component bolts and welding nodes. However, in the actual construction process, due to factors such as site factors and the angle of the steel structure, the high-altitude working space is limited, and the welding operation of some welds is inconvenient. Even if a crane is used in conjunction with an aerial work vehicle, such as the high-altitude operation form with a cable above the crane, the steel structure arch beam is at the top, and workers lack operating space and cannot directly contact the welding points or other construction targets located above, which may result in loose welding or even leaking welds.
