Important: A profile butt joint of the vertical bearing profiles behind a panel is not allowed! See standard technical detail drawings.
Substructure
The mounting of the substructure must be carried out according to project-specific, static calculation. The general approval Z-33.1-1175 of the construction supervisory authority must be observed.
The profiles have to be mounted perpendicularly and in a flush way.
The distance of the rails in horizontal direction must correspond to the longitudinal grid of the panels.
The length of the vertical profiles must be divisible by the height of the panel format and should not exceed the height of a storey of the building.
For further information, see the standard technical details of the system K20, which we will make available to you on request.
