What are the different types of building scaffolding?
Most of the construction scaffolds fall into one of the three general categories: self -supporting, suspension or scaffolding with special use. The self -supporting scaffolding consists of work platforms and various structures that support them, with the most common mounting method is the design of the tube and bindings. Other self -bearing types include a mobile, made frame and pole scaffolding. Scaffolding suspension is suspended from above ropes or other non -nigidic methods and includes many variations of specific work. Similarly, scaffolding on the construction of special use has many different forms of dictated types and placement performed.
The self -proprietary scaffolding includes those that have welded tubular frames composed of end images that have integral columns and horizontal carriers, plus intermediate members to support work platforms. The tube and the scaffolding tube structure are built using bonds that associate with different members, including runners, braces, anaopation carriers. Supported mobileThe scaffolding can be powered or sick, mounted on wheels or tracks and usually have a tubular and fasteners. Single -pole scaffolding is supported on one side by a series of poles and other members and on the other side by the building itself. The two -pole scaffolding platforms are supported by a double row of columns that are independent of the main supports.
Building regulations and the rules of safety in the US generally require that the scaffolding of the suspension and each component be able to support at least four times higher than the load rated. Ropes, cables and other hardware used to adjust the scaffold height must be able to withstand six times the load. Support hardware, such as cornice and roof hooks and window sills, are made of high -fixed steel or similar materials. Scaffolding scaffolding includes eitje driven or manual jack and brake that safely moves the workOvní platform up and down. If the platform starts too fast, the automatic brake or locking latch is designed to connect.
Special use of the design scaffolding, as the name suggests, is designed to deal with specific building conditions. The scaffolding roof holders are supported from the roof by means of triangular support support and brackets that are suitable for the slope and roof construction, while the scaffolding has platforms supported by boom that projected behind the wall of the building, while the inner ends of the scaffold are secured into the building itself. The pump scaffolding has a solid vertical support poles with moving support brackets, while the ladder and horse scaffolding are supported by ladders and horses. Aviation lifts are scaffolding mounted on a vehicle with power or single ports and include devices such as ladder and tower trucks, as well as articplatforms of ulaking and expandable boom.
