Temporary Roof
Hi Mart
We currently trying to sort out some standards design drawings which can be adjusted for each job at a relativelly small cost.
Problem with temporary roofs is that we have to consider the wind loads to check the ties, ledger braces, tensile loads in the the standards for uplift, and this is different for every part of the UK.
We have to use a wind code BS 6399 which varies from lowest loads generally in London, and getting higher towards Scotland. Only problem it also varies on altitude of site above sea level, if it is in an exposed location, etc.
So every job tends to be different due to shape and position of building, height above top tie, etc.
Problem is also that scaffold firms have all sorts of beams from unit beams to 780mm mitie diamond beams, some have system roofs, etc.
I think we will develop a standard roof scheme for small spans and use the worst case for say anywhere in England with unit beams, the lowest capacity 400mm and 700mm Ali beams first, with CI sheets and monarflex down to top boarded lifts.
We will be sorting out a standard design request form which we can check to see if you scheme is within these parameters and then issue a site specific drawing and calcs from a standard design.
Early days for this though so wont promise anything at the moment.
Hope PW sorted something out for you though.
All the best.
