Bar is also an essential component of light scaffolding, used to connect the pole, and from the start pole, pole, diagonal rod, bolt and other components composed of socket type light scaffolding.
More of the specifications of the bar, there is 300 mm, 600 mm, 650 mm, 750 mm, 900 mm, 1150 mm, 1200 mm, 1500 mm, 1800 mm, 2100 mm, and strengthen the cross bar, its specifications will be a lot less relatively, there are two main types: 1800 mm and 2500 mm.
The bar material is q235b, precision pipe, hot-dip galvanized, each pipe has a special custom steel seal.
Scaffolding is a work platform set up to ensure the smooth progress of each construction process. According to the position of erection, it is divided into outer scaffold and inner scaffold; According to different materials can be divided into wood scaffolding, bamboo scaffolding, steel scaffolding; According to the form of construction, it can be divided into vertical scaffold, bridge scaffold, door scaffold, suspended scaffold, hanging scaffold, scaffold, scaffold, scaffold.
Scaffold Development History:
In the early 1980s, China has introduced many types of scaffold, such as portal scaffold and bowl scaffold. Portal scaffold in many domestic engineering has also been widely used, achieved good results, because of the quality of portal scaffold products, the scaffold has not been widely used. In the domestic has built a batch of gate type scaffolding production factory, its product majority is processes according to the foreign merchant to plan. Bowl-buckle scaffold is a new type of scaffold in the promotion and application of the most, but the use of the surface is not wide, only part of the area and part of the project application. Since the 1990s, some domestic enterprises introduced foreign advanced technology, developed a variety of new scaffolding, such as the latch type scaffold, CRAB module scaffold, disk type scaffold, square tower scaffold, and various types of scaffolding. Up to 2013, more than 100 domestic professional scaffolding production enterprises, mainly in wuxi, guangzhou, Qingdao and other places. From the technical point of view, China’s scaffolding enterprises have been able to process the production of a variety of new scaffolding capacity. But the domestic market has not formed, the construction enterprise to the new scaffold understanding is insufficient. With the emergence of a large number of modern large-scale building systems in China, fastener-type steel tubular scaffold has been unable to adapt to the needs of construction development, and it is urgent to vigorously develop and promote the application of new scaffold. Practice has proved that the use of new scaffolding is not only safe and reliable construction, assembly and disassembly speed, and scaffolding with steel can reduce 33%, assembly and disassembly efficiency more than two times, the construction cost can be significantly reduced, construction site civilization, clean.Lightweight Scaffolding
