Description

Technical Field

[0001] The utility model relates to the technical field of building construction equipment, in particular to a telescopic and movable building scaffold. Background Art

[0002] Scaffolding is a working platform set up to ensure the smooth progress of each construction process. According to the location of the scaffolding, it can be divided into external scaffolding and internal scaffolding; according to different materials, it can be divided into wooden scaffolding, bamboo scaffolding, and steel pipe scaffolding; according to the structural form, it can be divided into vertical pole scaffolding, bridge scaffolding, portal scaffolding, suspended scaffolding, hanging scaffolding, cantilever scaffolding, and climbing scaffolding. Scaffolding refers to various supports set up at the construction site for workers to operate and solve vertical and horizontal transportation. It is used in exterior walls, interior decoration or places with high floor heights that cannot be directly constructed. It is mainly for construction workers to go up and down or for external safety net enclosures and high-altitude installation of components. In the existing technology, the height of most scaffolding is fixed and cannot be adjusted. However, in the actual use process, it is often necessary to adjust to a suitable height according to needs. The scaffolding is not easy to move and cannot well guarantee the stability of the scaffolding, which has great limitations. In addition, during the construction process, there are also great hidden dangers to the safety of construction workers; therefore, we propose a retractable and movable construction scaffolding to solve this problem.
