1)The allowable loads Nzul / Vzul were determined from the average values of the breaking loads, taking into account a safety factor γ = 4 (γ = 5 for vertically perforated bricks). Design and dimensioning
shall be carried out in accordance with the Friulsider design guide.
2) Anchoring base without plaster layer.
concrete: hnom = 30mm
solid masonry: hnom = 40mm
honycomb brick (Bimattone): hnom = 60mm
3) Pine wood average gross density ρk = 450 kg/m3 / moisture content approx. 12 % / fiber direction α > 30°.
Pine wood: hnom = 40mm
5) The installation torque must be adjusted according to the type of installation and the anchoring base.
