The invention includes a method of building an offset scaffold platform to an existing scaffold structure by using pivoting horizontal scaffold truss members, where each truss has a first end with a pivoting connector that pivot vertically and second ends that have second connectors that pivot horizontally. Each pivoting connector has a movable latch that, when latched, restricts uncoupling from a coupled vertical scaffold member but allows the pivoting coupled truss to remain moveable about the pivoting connector. The method includes the step of connecting one truss to a vertical scaffold member in an existing frame about the vertically pivoting end and connecting the second truss to another vertical scaffold member in the existing scaffold structure about one of its pivoting ends. Each pivoting connector latch is moved to the latched position, each truss is pivoted about its coupled end, and the uncoupled ends are each connected to vertical scaffold members which are supported from an overhead structure. Scaffold boards are positioned between the pivoted trusses to create a working surface therebetween.

Disclosed herein is a clamp for interconnecting two components of a support apparatus such as components of a shoring apparatus for concrete forming systems. A clamp member having a moveable jaw is received for pivotal movement in a housing that is secured to one of the components. A plurality of flutes disposed at an angle to the pivot axis of the clamp member are received in coacting recesses in the housing and a proximal cap maintains the desired position of the clamp member within the housing. Axial movement of the clamp member will pivot the swing arm and a coacting, moveable jaw toward a fixed jaw formed in the housing to releasably secure the clamp to the other component.

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 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.

The disclosure is directed to a clamp for connecting a ledger to a shoring post. The clamp includes a base member, a ledger-connecting member, and a first jaw, which are fixed connected to each other. The clamp includes a rotatable member inserted into the base member, which is rotatable and slidable in the base member along a longitudinal axis. A portion of the rotatable member is accessible via the slot of the base member. The clamp includes a second jaw fixedly connected to the rotatable member. The clamp further includes a wedge, and when the wedge is inserted into the slot of the base member to engage the rotatable member in a lock position, the first and second jaws are locked to capture two sides of a shoring post.

During erection of a scaffolding use is made of a coupling device with a base part (20) which is connected temporarily, but reliably, to a distal section of a ledger element (10) and to a coupling part (30) extending from the base part (20). The coupling part (30) comprises at the outer end a hook (35) which is placed round a subsequent upright (5) of the scaffolding in order to thus make a secondary connection thereto, while a primary connection (9,11) between the ledger (10) and the upright (5) is only completed later.

A fastening unit for attaching a first beam to a second beam is provided, wherein the second beam is arranged substantially perpendicularly to the first beam, the fastening unit having a first axis and a second axis, wherein the second axis is substantially perpendicular to the first axis. The fastening unit comprises a connecting member extending in a direction parallel to the first axis of the fastening unit and having a first edge portion, a second edge portion and a central portion, the connecting member further comprising a coupling element.
