Description

Technical Field

[0001] The utility model belongs to the technical field of subway station construction, and in particular relates to an integrated mechanical and electrical decoration bracket device used in subway stations. Background Art

[0002] The integrated support device refers to various supports set up at the construction site for workers to operate and solve vertical and horizontal transportation. It is used for exterior walls, interior decoration or places with high floor heights that cannot be directly constructed. It is mainly used for construction workers to work up and down or for external safety net enclosures and high-altitude installation of components.

[0003] At present, construction workers need to climb scaffolding to reach the height to work when performing high-altitude operations. If the construction workers encounter an emergency while climbing, accidents may occur. At the same time, the climbing scaffolding ladder will become loose and slip after long-term use. During the work process, the construction workers need to carry a large number of tools to operate. When there are no tools, the construction workers need to return to the ground, which will seriously affect the work progress and reduce work efficiency. At the same time, carrying a large number of tools for climbing will bring a large physical burden to the construction workers. Utility Model Content
