A scaffold clamp cooperates with a scaffold ledger to accommodate aligned placement of the scaffold clamp to the ledger at modular positions in the length of the ledger. The scaffold clamp includes an inwardly directed alignment lug sized for receipt in one or more clamp locating holes provided in the length of the ledger at modular positions. This arrangement provides accurate securement of the clamp to the ledger at predetermined modular positions and reduces problems that can occur with respect to erection of the scaffold system.

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 telescoping work platform utilizing three planks that are slidable to each other allows for a longer maximum length for use while providing for a shorter collapsed length for storage all while providing necessary structural support. The two outer planks comprise prongs that slide within channels of the inner plank.

A construction member is a construction member provided on a scaffold construction body, including a base material of foamed synthetic resin, and a coating layer of polyurea resin covering a surface of the base material. A falling object receiving device has a construction member that projects from a scaffold construction body toward an external space as a falling object receiving device panel, and includes an attachment part attaching a proximal end side of the falling object receiving device panel to the scaffold construction body.

Scaffolding element (100) with insulation, said scaffolding element (100) comprising a frame (110) of metal braces (111) and a set of fastening means (120), arranged to fasten the scaffolding element (100) to a supporting structure (20) of a scaffolding structure (10). The invention is characterised in that the scaffolding element (100) furthermore comprises a block (130) of insulating material, and in that the block (130) is cast around the frame (110), so that the frame (110) is completely covered by said insulating material but so that the fastening means (120) are not covered by said insulating material. The invention also relates to a manufacturing method and a kit of parts.

An electrically insulated trellis comprises a first array of parallel tubular members 2 and a second array of parallel tubular members 4. Each of the second array of parallel tubular members 4 is pivotably connected to a plurality of the first array of parallel tubular members 2 whereby to form a trellis 1. Each of the tubular members is formed from glass-reinforced polymer. A first set of fibres in the glass-reinforced polymer are substantially parallel and aligned in a first direction and a second set of fibres in the glass-reinforced polymer, distinct from the first set, are substantially parallel and aligned in a second direction different to the first direction.
