Described herein is a support element that may be a cantilever arm and a support structure being formed from multiple support elements for example to form a platform. Methods of assembly and use are also described. In one aspect, a support element is described with an elongated shape, a distal end and a coupling end and a cantilever form, where the coupling end of the support element is configured to couple with a structural member, the support element further configured to rotate once coupled from an inclined or declined position to a substantially horizontal plane, the support element once rotated to a substantially horizontal plane, extending generally orthogonally away from the structural member to a termination point about the distal end of the support element.

A scaffolding assembly adapted to be releasably attached to an elongate support member such as an overhead pipe. The scaffolding assembly has a split collar and a platform assembly adapted to be releasably attached to the split collar. The split collar comprises at least two segments which can encircle the pipe and be secured to one another. The platform assembly which includes a platform deck has a connector formation which extends laterally outwardly from the deck to an extent that it can engage a receiving formation on the collar assembly and thereby attach the platform assembly to the collar assembly.

An anchor for self-climbing structure of the type used on vertical or near-vertical concrete surfaces that uses metal inserts in the precast concrete tower and interlocking spikes in the self-climbing structure that are provided with rotary and rocking movement is disclosed. The anchor affords the main advantage of minimising tensile and shear loads on the concrete of the tower with maximum contact and optimum load distribution, while also achieving self-correction of possible coupling positioning and alignment errors. All of this results in improved delivery and distribution of the loads from the climbing device to the concrete wall and general structure that allows larger sized loads to be lifted and withstood than existing devices.

A plank scaffold system and, more particularly, to a ladder-based vertically-adjustable plank scaffold system. The system may have a pair of ladders, a wall standoff mounted at the top of each of the ladders, a crane support mounted at the top of each of the ladders, a vertical guide bar and roller system to keep it from swinging on the cables, and a horizontal platform suspended on cables below the crane supports, the platform having a pair of cable winches mounted thereon for varying the elevation of the platform. Instead of ladders, tower scaffolds or stage towers may be used on each side to support the vertically-adjustable plank.

A valley roof bracket is an adjustable V-shaped bracket having an upper cross-member upon which a triangular shaped platform may adjustably be positioned. The device may be secured to an angular side of a pitched roof.

A temporary shield erected between two flanged structural members of a bridge or other structure, and a method for erection of the shield. A plurality of length-adjustable beams have end portions which are rested on flanges respectively of the structural members in a manner so that they are not fixed thereto. Decking is attached to the beams. At least one elongate member is cantileverly extended from at least one of the beams to underlie a structural member flange to prevent wind lift-up of the shield. A shield is also erected by adjusting the lengths of and hanging the end portions of each of a multitude of beams from the structure with the beams lying side-by-side. Decking is attached to the beams.
