BS1139 Scaffolding tube

The type of scaffolding tube and the application of construction Scaffolding refers to the construction site for the workers to operate and solve the vertical and horizontal transport and erected a variety of stents.Construction of the general terms of the construction industry, refers to the construction site used in the external walls, interior decoration or high height can not be directly construction of the place mainly for construction Personnel from top to bottom work or external safety net maintenance and installation of high-altitude components, etc., that white is the shelf, scaffolding production materials are usually: bamboo, wood, steel or synthetic materials, etc. Some works also use scaffolding as a template, , Municipal, traffic, road and bridge, mining and other departments are also widely used. China in 1949 and early 50s, the construction scaffolding are used bamboo or timber erection method. 60 years from the promotion of fastener steel scaffolding. 80 years...

BS1139 Scaffolding Tube (1) heavy scaffolding should have a clear understanding of the general if the floor thickness of more than 300mm, it should be considered in accordance with the design of heavy scaffolding, scaffolding load more than 15KN / mm2, should organize experts to distinguish those parts of the steel pipe length change Bearing the impact of a larger, for the template bracket should consider the upper free length a should not be too long, generally less than 500mm is appropriate (in the new specification may be revised), pole calculation is generally the last step and the bottom step of the largest force, Should be used as the main calculation point. When the carrying capacity of dissatisfaction group requirements should increase the pole to reduce the pace. (2) the current domestic scaffolding ubiquitous steel pipe, fasteners, jacking and the end of the material quality and other substandard, the actual construction of the theoretical calculation did not take into...
