FIELD: scaffolding frames.
SUBSTANCE: invention relates to vertical frames made of metal, in particular frames for scaffolding. The effect is achieved by the fact that the wedge assembly includes a post with a disk with holes and crossbars with wedge-shaped heads with a wedge, while the end contact surfaces of the wedge and the disk hole repeat each other and are asymmetric with respect to the axis of the wedge and the hole.
EFFECT: increasing the operational reliability of the frame due to additional fixation of the wedge with asymmetric end surfaces by twisting across the wedge under dynamic influences.
