Description

Technical Field

[0001] The utility model relates to the technical field of scaffolds, in particular to a scaffold with adjustable height. 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. It refers to the places on construction sites where exterior walls, interior decoration or high-rise buildings cannot be directly constructed. It is mainly used for construction workers to go up and down or for external safety net protection and high-altitude installation of components. Of course, scaffolding also has other uses. Some projects also use scaffolding as templates. In addition, it is also widely used in advertising, municipal administration, transportation roads and bridges, mining and other departments.

[0003] At present, some scaffolds cannot effectively adjust the height or cannot adjust the height, and are connected into a whole, which reduces the scope of application and has poor safety and usability.

[0004] To this end, we invented a scaffolding that can adjust the height. Utility Model Content
