A scaffolding assembly is disclosed. The system includes scaffolding poles joints (or fittings) for releasably securing the poles at cross-over points. Each scaffolding joints has an inner body member and two movable outer clamping members to clamp the poles to the body member at the cross-over points. The body member also has as a mounting for a safety connection member which projects laterally the scaffolding poles towards an operative. The safety connection member can be connected to a safety tension member from the operative such that a safety connection point is available at each of the scaffolding joints.

A prop-brace coupler has a first section configured to be selectively connected to a vertical prop member of a construction platform that includes a vertical spacing member and a diagonal bracing member. The prop-brace coupler also has a second section configured to be selectively connected to the vertical spacing member and to the diagonal bracing member.

A combined member, comprising a communication rod (1) and a connecting rod (2), wherein the connecting rod (2) comprises a rod body (2.1) and a connector (2.2), the connector (2.2) being a fastening connector (3) or a sleeving connector (4), the rod body (2.1) of the connecting rod (2.1) and a rod body of the communication rod (1) being of a strip-shaped structure, the connecting rod (2) being connected to the communication rod (1) by the fastening connector (3) or the sleeving connector (4), the axis of the connecting rod (2) intersecting that of the communication rod (1) connected thereto. The combined member has the advantages of high bearing capacity, and convenient construction.

A mechanical coupling arrangement for a scaffold includes a pole and a mounting collar having an attachment surface to which elongated support members can be attached. A level of radial play between the pole and the mounting collar in a first relative angular position is larger than the level of radial play between the pole and the mounting collar in a second relative angular position. The second relative angular position corresponds to a fastening position of the mounting collar, and the first relative angular position corresponds to an axial sliding position of the mounting collar.

A scaffold system for supporting workers includes a plurality of end frames including a pair of uprights joined by an overhead cross bar for supporting planks thereon. The end frames are stacked top-to-bottom to form end frame columns and are laterally secured together to form an exterior framework. The scaffold system also includes interior posts coupled vertically end-to-end so as to form interior columns, with pairs of interior columns being secured to each end frame column between the vertical uprights of the end frames. Side rails are mounted to the interior posts extending between the pairs of interior posts. Planks are supported on the overhead cross bars, extending between adjacent end frames, and are bounded at their ends by the pairs of interior posts to form a work space and/or walkway for workers of a reduced size or area.
