Les étais de coffrage devront être

Les étais de coffrage devront être disposés de telle sorte qu’ils ne donnent sur les surfaces d’appui inférieures que les efforts compatibles avec leur résistance et tels qu’ils ne provoquent notamment aucun enfoncement ou déformation, qui entraîneront par voie de conséquence une déformation du coffrage.

Formwork props must be arranged so that they give on bearing surfaces less than compatible with their resistance efforts and as they cause including any deflection or deformation, which will consequently deformity of the formwork.

Was the formwork must be arranged so that they open to the lower bearing surfaces that effort consistent with their resistance and as such not cause any deformation or penetration which will result consequently a deformation the formwork.

The stays of shuttering should be arranged so they do not give on the surfaces of lower support that the efforts compatible with their resistance and such that they do not cause including no indentation, or deformation, which will result in consequence a deformation of the casing.
