After the snow sweeping steel roof snow to avoid collapse

Time:[2014-6-14]  Hits:4982

Some steel construction collapsed at the beginning of the design there is a problem, some companies to reduce costs, casually invited guerrillas construction, the construction itself is low quality, so a bad weather, the problem is exposed, and this is the time Many gas stations, industrial plants stand up to wind and snow simple test of a major factor. Quiz heaviest snow per square meter 90 kg, and the lack of snow and ice melt, the formation of two snow backlog, the construction of additional load.

 

On industrial plants, vegetable greenhouses and other construction backlog snow collapsed things often happen, and these are mostly used in the construction of the collapse is light steel structure. Snow removal for the current status of the object we are more concentrated in the road, and co-workers about the steel industry experts and Foshan appeal: Winter snow to sweep the floor to the roof in addition to more snow, the snow must as soon as possible on the cleanup of industrial plants to avoid the backlog overweight causing collapse. Light steel construction doubt why repeated collapse?

Some houses do not appear collapsed, but there are still many problems, not overloading beams also cause deformation recovery, significantly decreased the formation of strong wind resistance to the construction material, and under the roof of the scratch will lead to poor roof drainage, simple leaking. Thus, when the winter snows, Nanning steel construction units must prompt the owners to do Kiyoshi preparation.
