Load capacities of individual connecting elements In addition to the listed load-bearing capacity of the individual fastening elements in shearing, a possible block shear failure was taken into account in the load-bearing capacities, see DIN EN 1995-1-1, Annex A.
Connection over intermediate layers The specified load-bearing capacities also apply to intermediate layers if the following requirements are met: Intermediate layer: • OSB boards type OSB/3 and OSB/4 according to EN 13986 (EN 300) or approval • Synthetic resin-bonded chipboard in accordance with EN 13986 (EN 312) or approval • Solid wood panels according to EN 13986 (EN 13353) or approval • Plywood according to EN 13986 (EN 636) or approval • Plasterboards according to approval • Fibreboards according to EN 13986 (EN 622-2 and 622-3) minimum raw density 650 kg/m 3 The value of the characteristic bearing strength of the intermediate layer must at least fulfil the value for solid softwood of strength class C24.
The compressive strength of the intermediate layer when loaded at right angles to the connecting surface (for wood-based panels, compressive strength perpendicular to the board plane) must be at least equal to the value of the compressive strength perpendicular to the grain for solid softwood of strength class C24.
