Abstract: A connector assembly for a scaffold structure having an upright member or standard and a cross member, comprising an open-ended V or channel-shaped socket fixed to the upright member and a channel-shaped connector member fixed to an end of the cross member. In the fully assembled position, a base flange of the connector member is held, by means of a wedge element, in tight engagement with the outer surface of the socket and arms extending outwardly from the base flange, and over opposite ends of the socket, are such as to be spaced from the outer peripheral surface of the upright member. For location purposes, the free end of the uppermost arm of the connector member is formed with a downwardly depending tongue, or alternatively, the side edges of the uppermost arm are provided with downwardly depending flanges.

Abstract: The invention is concerned with a drop-head support assembly for use with builders scaffolding and is directed to an assembly comprising an upright pillar, a shuttering support member slidably mounted on the pillar, and a wedge device pivotally attached to the pillar to be moved between a horizontal position where it supports the support member and a vertical position where it releases the support member. The upper end of the pillar may also be adapted to receive a detachable head plate device.
