Boarding for ceilings has rigidly interlinked grid elements made up of longitudinal and transverse spars each fitted on vertical supports

摘要

Longitudinal (4) and transverse (5) spars for grid elements (2) rigidly interlink. Standard grid elements have two transverse spars in the end areas of the longitudinal spars opposite each other. Transverse balancing grid elements have one or two transverse spars staggered inwards in comparison with the standard grid elements.
