At present, many projects require high-altitude operations, and scaffolding role is particularly important. Scaffolding tube is a temporary construction essential facilities, such as turn masonry walls, pouring concrete, wall plaster, stucco decoration and installation of structural members, would require the erection of scaffolding next to it, in order to stand on top of the construction operation, the level of short-distance transport and construction materials stacked when necessary.

Building scaffolding tube facade set into the ground state, cantilevered, hanging, attached to lifting four basic forms.

① floor-erection of scaffolding on the ground outside the building, the main method for the pole double erection. Pole carrying capacity due to restrictions, combined with a large amount of material consumption, take a long time, so that the height of scaffolding erection and more control in 40m or less. Housing construction in brick and concrete structure, which doubles as a masonry scaffolding, decoration and protective use; to construction of multi-frame, the scaffold mainly for decoration and protection purposes.

② cantilevered scaffolding erection of buildings on the outer edge of the outwardly extending cantilevered structure, the scaffolding will be passed to load all or part of the building structure. Support structure under the cantilevered support structure useful for the production of welded steel wire rope and a triangular truss pulled oblique horizontal beam pick Diagonal two major forms of structural beams. On the double cantilever structure erection of scaffolding outside the same floor scaffolding, scaffolding cantilevered segment height is generally controlled within 25m. This form of scaffolding for the renovation and protection purposes, used in construction of high-rise buildings in downtown needs to be closed in to prevent falling objects wounding.

Although the scaffolding with the progress of works and erection, construction completion on the demolition, but its construction speed, efficiency, quality and the safety of workers has a direct impact. If scaffolding erection is not timely, it is bound to delay the progress of the project; construction scaffolding erection does not meet the needs of workers to operate not convenient, quality can not be guaranteed, it is not improved ergonomics; scaffolding erection is not firm, unstable and likely to cause construction of casualties.
