Scaffolding is a kind of scaffold for workers to operate and handle vertical and horizontal transportation at construction site. General terminology in the construction industry refers to the construction site used in the external wall, internal decoration or high-rise can not be directly constructed in the center. Mainly for the construction of personnel up and down work or periphery safety net enclosure and aerial device components, to put it plainly is to build a scaffold, scaffolding manufacturing materials are usually: bamboo, wood, steel pipes or composite materials. Some projects also use scaffolding as a template, in addition to advertising, municipal, transportation, roads and bridges, mines and other departments are widely used.
Before 1949 and early 50s, scaffolding was constructed by bamboo or timber in China. Since 60s, the fastener style steel pipe scaffold has been introduced. Since the 1980s, China has made remarkable achievements in developing advanced and multi-functional scaffolding series, such as portal scaffolding series and bowl-buckle steel tube scaffolding series, with an annual output of over 10,000 tons and a certain number of exports.
For a long time, because the erection tool itself and its structural technology and the use of safety management work in a relatively backward state, resulting in a higher incidence of accidents. Relevant statistics show that about one third of the casualties in China's construction system occur every year, directly or indirectly related to the problems of erecting tools and their application.
With the maturity and perfection of China's construction market, bamboo-wood scaffolding has been gradually eliminated from the construction market, only in some remote and backward areas are still in use; while door-type scaffolding, bowl-button scaffolding and so on are only used in municipal works, bridges and other small projects, ordinary fastener-type steel tube scaffolding because of its simple maintenance and operation. Long life and low investment costs and other advantages, occupying more than 70% of China's domestic market, and has a greater space for development.
