A scaffold system comprising a set of components adapted for assembly of a scaffold section. The components are at least two frame components, each having at least two vertical members separated by at least two interconnecting members, the at least two vertical members comprising a socket; two or more brace components adapted to span between and connect to the two side frame components; at least four corner pole components, each adapted to connect with the socket of a vertical member; and a plurality of support rail components adapted to span between two pole components.

A scaffold includes first and second ladder frames. Each ladder frame includes a first and second vertical supports, a center support, rung(s), and upper and lower horizontal supports. The upper horizontal support is formed of tubular material, and has a central section and flattened end sections mounted to corresponding vertical supports. The center support and/or rungs advantageously have coped and slightly flattened end sections. Recesses formed by the flattened end sections provide space to partially receive vertical or horizontal supports of another ladder frame when the frames are stacked, thereby reducing overall stack height.

One embodiment of the invention is a horizontal scaffold truss that has upper and lower horizontal scaffold members offset but fixedly joined with braces. Each upper and lower members have a connector positioned on each end of the respective lower and upper members, where at least one of the connectors is pivotally mounted on the respective lower or upper connector, and the connecters are engageable with an annular member positioned on a vertical scaffold member.

A clamp for securing a plank to an elongated member of a scaffold. The clamp includes a body and a pair of legs extending from the body longitudinally spaced apart from each. The legs each define a leg recess for receiving the elongated member, the leg recesses each defining a leg recess nadir at a location furthest away from the body. A lock is mounted to the body and defines a plank engaging tip, the lock being movable between a lock extended position and a lock retracted position. In the lock extended position, the plank engaging tip is closer to the leg recess nadirs than in the lock retracted position.

A collapsible structural frame for forming a soffit having a multi-planar surface. The collapsible structural frame includes a first frame portion configured to receive a first sheet of building material, a second frame portion configured to receive a second sheet of building material, the second frame portion extending along a second reference plane, and a third frame portion configured to receive a third sheet of building material. The collapsible structural frame is alterable from: (1) a flat state in which the first, second, and third frame portions extend along the second reference plane in a linear arrangement; and (2) a deployed state in which the first frame portion is out of plane with the second reference plane and the third frame portion is out of plane with the second reference plane;
