A scaffold crossbar, particularly for the horizontally oriented installation in a scaffold section, comprising at least one crossbar beam which has a rod-shaped design and extends in the direction of a longitudinal axis, wherein the crossbar beam has two opposite ends in the direction of the longitudinal axis, and a connection interface which is provided for the connection to a scaffold element is arranged on each of these two ends. The scaffold crossbar further comprises at least two brackets which extend along a bracket axis, respectively, wherein the brackets respectively have two opposite ends in the direction of their bracket axis, wherein one of these ends of each bracket is connected to the crossbar beam, and at least two fasteners respectively one of which is arranged on the end of a bracket which is situated opposite of the connection of this bracket to the crossbar beam.

A scaffold node for connecting scaffold elements extending in different spatial directions, comprising a connecting sleeve which is provided as a coupling point for two scaffold components, in particular for two vertical posts or for a vertical post and a spindle nut post, and at least one coupling element which is used to connect the scaffold node to further scaffold components or scaffold elements. A scaffold portion comprising a scaffold node and further scaffold elements.

A modular decking system comprising a decking panel, a plurality of vertical supports, at least two first horizontal supports, at least two second horizontal supports arranged perpendicular to the first horizontal supports, one or more third horizontal supports arranged between the first horizontal supports and parallel to the second horizontal supports, and a plurality of connectors for detachably coupling the first and second horizontal supports, is disclosed. The connectors include an elongate tube adapted for insertion into the vertical supports and a connection hub. The connection hub and the ends of the first and second horizontal supports include reciprocating formations to enable the respective ends of the first and second horizontal supports to slidingly engage with the connection hub.
