Description

Technical Field

[0001] The invention relates to the technical field of high-rise building engineering, and in particular to an integrated wall attachment device based on synchronous climbing of a light steel platform. Background Art

[0002] During the construction of traditional super-high-rise buildings, the construction elevator can only run to the bottom of the top formwork / climbing formwork, and needs to pass through the outer protective walkway board of the top formwork / climbing formwork to reach the working surface, which is inefficient and not conducive to the needs of on-site observation and inspection of large-scale projects. The project also has a double guide rail device to achieve the purpose of synchronous climbing, but the steel guide rail frame will double the amount of work and the cost is high. The fundamental reason for the above problems is that the top operating surface of the top formwork or climbing formwork is higher than the construction working layer, and there are no attachment points in the middle and top for the guide rail to be raised. The specification requires that the spacing between the wall attachment devices of the construction elevator must be less than 10.5m, and the top free end must be less than 7.5m. In particular, some areas require that the last exit layer of the elevator must have an attached wall on its top, which further increases the difficulty of the top formwork / climbing formwork operating surface on the construction elevator. Summary of the invention
