Description

Technical Field

[0001] The utility model belongs to the technical field of scaffolds, and particularly relates to a scaffold with rapidly adjustable height. Background Art

[0002] Scaffolding is a temporary structure erected at a construction site to provide a safe working platform for construction workers and to solve the problem of vertical and horizontal material transportation during building construction. It is an auxiliary structure that ensures that workers can perform operations at different heights, such as concrete pouring, wall construction, decoration or installation. Scaffolding is usually composed of assembled parts, such as steel pipes, fasteners, wooden boards or synthetic boards. These materials are combined according to design requirements to form a stable support system. With the development of technology, modern scaffolding systems pay more attention to safety, stability and ease of assembly to meet the needs of different projects. In China and other regions, fastener-type steel pipe scaffolding is widely used due to its practicality, economy and durability.

[0003] Some scaffoldings may not fully consider the need for frequent height adjustment during the construction process in the early stage of design, which makes it difficult to quickly adapt to work surfaces of different heights in actual applications. Most of them rely on manual construction and adjustment, including tightening or loosening fasteners, moving the position of poles, etc. This is not only time-consuming and labor-intensive, but also inefficient and difficult to achieve rapid height adjustment. Therefore, we hope to design a scaffolding with a new structure to solve this problem. Utility Model Content
