Scaffolding is a variety of supports erected on the construction site for workers to operate and handle vertical and horizontal transportation. A general term in the construction industry, refers to the construction site used in the center of the exterior wall, interior decoration or high storeys that cannot be directly constructed. Mainly for construction personnel to work up and down or to protect the outer safety nets and high-altitude installation components. To put it bluntly, it is to build the scaffolding. The scaffolding materials usually include: bamboo, wood, steel pipe or synthetic materials. Some projects also use scaffolding as templates, and are also widely used in advertising, municipal administration, traffic roads and bridges, mining and other departments.
Before 1949 and in the early 1950s, China used bamboo or wood to erect scaffolding. The fastener-type steel pipe scaffolding was introduced in the 1960s. Since the 1980s, China has made remarkable achievements in the development of advanced and multi-functional scaffolding series, such as portal scaffolding series and bowl-buckle steel pipe scaffolding series. The annual output has reached tens of thousands of tons, and there have been a certain number of Exit.
For a long time, due to the relatively backward state of the erection tool itself, its structural technology and the use of safety management, the occurrence rate of accidents is high. Relevant statistics indicate that about one-third of the casualties that occur in China's construction system every year are directly or indirectly related to problems with erection tools and their use.
With the increasing maturity and improvement of the Chinese construction market, bamboo and wood scaffolding has gradually been eliminated from the construction market, and is still used in some remote and backward areas; while portal scaffolding and bowl-buckle scaffolding are only used in municipalities and bridges. In engineering applications, ordinary fastener steel scaffolds occupy more than 70% of China's domestic market due to their simple maintenance, long service life, and low investment costs, and have a large development space.
