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.

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.

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 structural support system, such as, a scaffolding or a falsework comprising verticals (10) and horizontals (40) connected at node sections (120) at the verticals (10), each node section (120) comprising a locking device for joining horizontals (40) and/or diagonals with bladed ends arranged at ends of the horizontals (40) and the vertical (10), where the locking device is a cup pair comprising a bottom cup (20) held at a position on the verticals (10) and atop cup (30) moveably arranged on the verticals (10), where bladed ends of the horizontals (40) or diagonals are configured to be locked by bottom cup (20) part and top cup (30) part, providing a rigid connection. That is characterized in that parts of the structural support system intended to be held at a position on the verticals (10) are held by using one or more fastening means (50) and corresponding hole(s) (11, 25) in the parts and the verticals (10), the fastening means (50) being rigidly fixed by screwing a headed bolt into the vertical (10), providing a compressive vertical load in vertical and/or horizontal direction capacity of the lower cup via the bolt.
