Abstract: A joint forming structure produced integrally as a bent metallic sheet having a continuous cross-sectional configuration. The sheet includes a central trough having a parallel side walls and a perpendicular transverse base wall. It further includes a pair of oppositely bent longitudinal flanges joined to the respective side walls at their remaining longitudinal edges. The flanges terminate in longitudinal lips bent back along their outer edges and partially overlapping the side walls. The trough is shaped to receive upright supports when inverted over the supports, or alternately, to receive a board or other decorative joint material while upright supports are received within the smaller troughs presented by the flanges and lips at each side of the center trough.

Abstract: A form stake assembly for adjustably holding a concrete form at a prescribed grade. It includes a pointed stake that has an elongated slot slidably receiving the shank of a carriage bolt. The headed end of the bolt abuts one side of the stake. The bolt shank receives a wing nut on the other side of the stake. The wing nut may be selectively tightened to clamp the bolt against the stake or loosened to enable sliding movement of the bolt within the confines of the longitudinal slot. The bolt includes a central bore extending through the shank and head to receive the shank of a nail. The nail is utilized to secure a concrete form member to the carriage bolt and wing nut assembly. A tie rod is included that may extend between opposed stakes on opposite sides of the form area. The tie rod includes a headed end and a free end. The headed end abuts one side of one stake while the shank extends through the slots of both stakes to receive a slidable collar.
