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 connector for a modular scaffold, having a connector tube having a tube section with enlarged outer and/or inner diameter at least at one end, preferably at both ends, for connection to at least one vertical post, as well as a connector element which has at least one receiving recess for connection to at least one horizontal beam and/or a diagonal brace, wherein the connector element is fastened to the connector tube either indirectly via an extension arm or directly on the outer circumference.

A modular scaffold, a method of manufacturing a modular scaffold and a use of a connector within a modular scaffold.

A utility scaffold is designed to be repeatedly broken down into straighter components to reduce the space requirement for storage and shipment. The scaffold has first and second ladder frames, each comprising a plurality of vertical supports, a plurality of horizontal supports, and a plurality of releasable connections. The horizontal supports are releasably connected to the vertical supports by the releasable connections to form a rigid ladder frame structure. The releasable connections include a male wedge protrusion and a female receiver configured to receive the male wedge protrusion. The female receiver has a passage therethrough, with the passage having a tapered interior surface. The male wedge protrusion and the tapered interior surface are configured to abut when the vertical support and the horizontal support are mounted together via the releasable connection. A fastener is optionally used to secure the releasable connection.

A scaffolding tube clamp having a pair of body portions defining a top and a base that are hinged together and receivable about a scaffolding tube. A rotatable bolt is received through a hole in the top a hole in the base portion. The bolt has a lower end with engagement means to releasably secure the bolt to the base. The bolt's head has a lower surface that is engageable with a surface on the top. The lower surface of the head, and the surface of the top that is engaged thereby, have complimentary ramped configurations such that when the bolt is rotated the ramps engage, resulting in the ramps moving the top toward the base. In an alternate embodiment the bolt is threaded with two sets of threads that have different diameters and different pitches and that are threadably received within the holes in the top and bottom.

A scaffold upon which a person stands includes a platform with a first leg assembly rotatably attached to the platform. The scaffold includes a latch assembly having a latch pivot axis coupled to the platform. The scaffold includes a stud attached to a first leg of the first leg assembly to which the latch assembly engages when the first leg assembly is moved into the extended position to automatically lock the first leg assembly in the extended position where the latch assembly is in a set position. When the latch assembly is moved out of the set position, the stud on the first leg disengages from the latch assembly and the first leg assembly is able to rotate about the first leg assembly pivot axis to a folded position. A method for using a scaffold.

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.

A scaffold cross-bar of metal with a round-tube carrier profile of steel includes a round tube and has an outside diameter, and a U-shaped reinforcing profile of steel sheet. The U-shaped reinforcing profile has a base profile and two parallel profile legs which extend away from the base profile in the same direction at a transverse spacing from one another. Each profile leg has at least one opening for fastening and/or securing scaffold components on the scaffold cross-bar. The transverse spacing of the profile legs is smaller than 0.6 times the outside diameter of the round-tube carrier profile.

A scaffold transom, particularly for the horizontally oriented installation in a scaffold section, the scaffold transom comprising at least one transom support which is rod-shaped and extends in the direction of a longitudinal axis, the transom support having two opposing ends in the direction of the longitudinal axis, and a connection interface being located at each of these two ends, which connection interface is provided for the connection to a scaffold element, at least two brackets which each extend along a bracket axis, the brackets each having two opposing ends in the direction of their bracket axis, one of said ends of each bracket being connected to the transom support, and at least two closures respectively one of which is located at the end of a bracket opposite of the connection of said bracket to the transom support.
