Description

Technical Field

[0001] The utility model belongs to the technical field of scaffolds for building construction, and particularly relates to an auxiliary steel frame device for lifting a cross-layer of an attached lifting scaffold. Background Art

[0002] According to Article 4.4.8 of the Safety Technical Specifications for Tool-Type Scaffolding in Construction (JGJ202-2010) for attached lifting scaffolding, the cantilever height of the frame shall not be greater than 2 / 5 of the frame height and shall not exceed 6m. Since the climbing of the attached lifting scaffold is similar to that of the ordinary steel pipe scaffold, wall connecting parts need to be installed at certain intervals in the vertical and horizontal directions during the installation process. During the climbing process of the attached lifting scaffold, a wall support is generally installed vertically for each layer. The wall support is installed and fixed on the attached wall of the building. After the attached lifting scaffold climbs, it is interlocked and fixed with the climbing frame to play a pulling role; since the attached lifting scaffold is an integral lifting type, when a certain section of the structure has a leap floor, and the leap floor height exceeds 6m, the original position of the wall support cannot pull the climbing frame. At this time, if the attached lifting scaffold is to be completed The climbing of the scaffolding needs to be removed and the scaffolding pieces and wall supports of the matching structure need to be reinstalled. When the leap floor structure is adjusted to only one layer, it is time-consuming and labor-intensive to adjust the scaffolding pieces and wall supports of the climbing frame. Utility Model Content
