[edit] scaffolding

scaffolding in the design and construction problems

Mobile scaffolding there are problems in the design:

Of heavy mobile scaffolding should have a clear understanding of the general if the slab thickness exceeds 300mm, it should be changed to consider the design in accordance with heavy-duty scaffolding, scaffolding load over 15KN/mm2, the design should organize experts. To distinguish those parts of the pipe carrying a greater impact on the length change, support for the template should be considered: the top of the center line of a horizontal bar the length of a strong point from the template should not be too long, generally less than 400mm suitable (in the new specification may have to be revised), the general calculation pole top and bottom step by step by the maximum force should be calculated as the main point.

Capacity requirements should be satisfied when the group increased to reduce vertical and horizontal pole spacing decrease or increase the horizontal bar step. Prevalence of domestic scaffolding steel, fasteners, backwater, and the end of substandard quality care and other materials, the actual construction of the theoretical calculation does not consider these, it is best taken in the design calculation process certain safety factor.

Sweeping bar missing, vertical and horizontal junction is not connected, sweeping shot from the distance is too large or too small, etc.; scaffold board cracking, the thickness is not enough, did not meet the specifications overlap; large form after the removal of the medial pole and the wall is not between anti-dropping network; scissors in the plane did not continuous; opening brace scaffolding is not set; small bar under the scaffold board spacing is too large; even failed to do inside and outside wall rigid parts; protective railing spacing is greater than 600mm; fastener connection is not tight, fastening slippage.

Development and Prospect of scaffolding

The general trend is moving toward the scaffolding lightweight, high strength structure, standardization, assembly and function of the direction of development. Material from wood, bamboo development of metal products; erection process will be phased in assembly methods to minimize or without fasteners, bolts and other components; material will also be phased in thin-walled steel, aluminum alloy products. Scaffolding to enhance environmental protection requirements, the establishment of professional scaffolding contractors and so on.
