Abstract: An extension support member includes a bracket or web having a first planar portion or leg, a second planar portion or leg, an acute, concave angle between the first planar portion or leg and the second planar portion or leg, and a bend or backbone joining the first planar portion or leg to the second planar portion or leg. The extension support member also includes is a first mounting portion or tab joined to the second planar portion or leg via the bend or backbone at a first, convex obtuse angle and a second mounting portion or tab joined to the first planar portion or leg via the bend or backbone at a second obtuse, convex angle. The first mounting portion and the second mounting portion are located at opposite ends of the bracket or web.

Abstract: An improved system for straightening and/or supporting a wall is provided. The system includes a joist spanner system that may be attached to an elongated vertical member positioned to abut a wall. The joist spanner system may include an inner bracket and an outer bracket in slidable or telescopic communication with one another. The inner bracket and outer bracket may each include a slot or track to provide slidable or telescopic adjustment of the spanner system. The slot or track may also provide an adjustable point for attaching the spanner system to the elongated vertical member. The inner bracket and outer bracket may also each include an end plate configured to be positioned to abut opposing joist members. The end plates may also include one or more apertures configured to receive a fastener for securing the spanner system to opposing joist members.

Abstract: An improved a system for straightening and/or supporting a wall is provided. The system includes an elongated vertical member and an elongated horizontal member positioned to abut the wall. The elongated horizontal member has a first end and a second end, the former being positioned adjacent to the elongated vertical member. A cinch plate having at least two plates is provided. One of the plates is connected to the elongated vertical member. A driving member can be movably coupled to the other plates of the cinch plate and configured to force the elongated horizontal member to move relative to the elongated vertical member. Movement of the elongated horizontal member applies a corresponding force to the wall. The elongated horizontal member may not be connected to the elongated vertical member, but rather a compressive force applied between the driving member and the wall can vertically support the elongated horizontal member.
