A collapsible structural frame configured to provide a structure to which building material sheets are attached to form a surface. The frame includes a first frame portion that corresponds to a first portion of the surface and is configured to receive a first sheet of the building material and a second frame portion that corresponds to a second portion of the surface and is configured to receive a second sheet of the building material. A pivoting mechanism attaches the second frame portion to the first frame portion and has a pivoting axis. The pivoting mechanism permits the second frame portion to rotate about the pivoting axis relative to the first frame portion from an undeployed state to a deployed state. A locking mechanism may fix a relative position of the first frame portion and the second frame portion in the deployed state.

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.
