Hello,

i am a french structural engineer, living in Spain, and about 90% dedicated to special scaffolding design, the left 10% being tensile structure and aluminum grids

I mostly work for Altrad group, or Altrad group clients

I study Metrix scaffolding, and have a lot of fun building 3d models using sketchup

Nice to find such a website; i don't know about anything equivalent in french...
 
Hi Giro

Welcome to the Forum

Glad to see another designer on here, especially European.

Do you have your own scaffold codes in Spain/ Europe beside EN 12811-1.

I have a design in Malta at the moment. What wind loads would you use over there ?

All the best

i live in Spain for the sunshine, mainly... but my clients are in France.
Since i work thru the internet, it doesn't make any difference
In France, we should use EN 12811-1 also, and eurocodes in general, but generally speaking, french codes are still in use
In Spain, as i understand, most of the time, they don't study the scaffoldings: some companies have an official agreement to erect scaffoldings, and that's it..
Concerning the wind speed in Malta, i found this
La carte des vents de l'Europe occidentale
considering where Malta is located, and comparing with Corsica, i would say vb,0 = 28 m/s reference wind speed according to the EN 1991-4
 
Bonjour et bienvenue sur le forum, je ne parle pas français, mais peuvent utiliser le traducteur de google et semblent bi-linguil

Hi Giro

Thanks for the info.

They seem to be quite tight on control of scaffolding UK compared to quite a few of the other developed nations in the world.

TG20:08 Technical Scaffolding Guidance on the use of BS EN12811-1

"The UK scaffolding industry should be fully conforming to the European Standard BS EN12811-1:2003 by the end of 2010 rather than the withdrawn British Standard BS 5973:1993."

So the situation seems to be about the same concerning European standards, in UK and in France.

There seem to be a big difference though: tubes and fittings are not used anymore in France; most of the scaffoldings are made with modular systems, or frames

The controls are made strictly in France also, especially in big cities
 
here is an example of how i use sketchup and an additional software to make a 3d model of the sacaffolding, show each line individually for control, and get a material list

Hi Giro

I dont have a problem with system scaffolds generally, but have never been able to work how to get around awkward shaped buildings with the set bay lengths and then not leave gaps on corners and other areas.

Do they have any controls on the width of gap between the building and the last inside board. ?

All the best

Hi,

by system scaffolds, i understand you mean modular scaffold, that is "not tubes and fittings"... right?

the width of gap between building and plank is 20 centimeters maximum

it is not a problem to implement, even around awkward shaped buildings, because many ledger lengths are avalaible

the modular scafolding system i mostly design is Metrix from Altrad Plettac, which a french version of Contur from Altrac Plettac

lengths available are 0.3, 0.4, 0.5, 0.7, 1.0 , 1.5, 2.0, 2.5, 3.0 m

2 ledgers 1.0 m and 1.5 m long on a gridline for example, can be replaced by 1 ledger 2.5 m long on the parallel gridline, so it is easy to follow the shape of the buidling without having to erect too many columns

this is not possible with any modular scaffolding; for example, Layher Scaffolding: ledger lenghts available are 1.09 m and 1.57 m; and there are no 2.66 m long ledgers avalaible in Layher system
