Description

Technical Field

[0001] The utility model belongs to the technical field of scaffolds, and in particular relates to a construction scaffold. Background Art

[0002] Scaffolding refers to various supports set up at construction sites for workers to operate and solve vertical and horizontal transportation. It is a common term in the construction industry, referring to the use of scaffolding on construction sites 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. To put it bluntly, it is a frame. Scaffolding is usually made of bamboo, wood, steel pipes or synthetic materials. Some projects also use scaffolding as a template. In addition, it is also widely used in the advertising industry, municipal administration, transportation roads and bridges, mining and other departments.

[0003] At present, in the process of construction, workers usually need to climb to a certain height with the help of scaffolding. When using traditional scaffolding, its height is mostly fixed. Workers need to climb to the scaffolding table with the help of ladders on the scaffolding. Since workers need a variety of tools during construction, it is inconvenient to carry tools during the climbing process, and the weight of the workers is increased, which is very inconvenient.
