The History of the Scaffolding
In China, before 1949 and the early 1950s, the construction scaffolding erection is bamboo or wood. In the 1960s, people began to promote the steel tubular scaffolding formwork. Since the 1980s, China in the development of state-of-the-art, with substantially the multifunctional scaffolding Series achievements such as gantry scaffold, cup-lock steel pipe scaffold series, with an annual output has reached the scale of tons, and there are a certain number of exports. For a long time, since the erection of the tool and its construction techniques and the use of safety management is lagging behind the state, resulting in a higher incidence of accidents. For statistical surface: the casualties occurred in the construction system, about 1/3 directly or indirectly are related to the erection of the tool and its use.
Scaffolding Quota
Scaffolding quota is usually divided into three types:
First, scaffolding has no actual pattern, such as in the Jian'an construction at the same site, there are a variety of projects need to use scaffolding, it can use this scaffolding, and other scaffolding installation projects can no longer occur. During the construction, the construction unit can be set up if needed. The high cost of this project. Second, the external scaffolding is exterior wall construction, scaffolding within the scaffold interior wall construction is the general civil construction, and civil construction cannot be applied within the scaffolding. Pipeline construction, but also in the height of more than 3.6 meters above the part, there will have scaffolding project. Third, if the height is not too high, and bearing little place, you can use a single row of scaffolding. Multi-storey building facade construction is using double scaffolding. The construction of high-rise buildings, scaffolding, must be done safety accounting because the repeated occurrence of high-level scaffolding accidents.
