Abstract: An adjustable rebar connector for joining rebar rods is disclosed. In some embodiments, the connector includes the following: a first portion including one or more arms, each of the one or more arms including a male portion extending therefrom and a first notch having a first longitudinal axis, the first notch being configured to releasably retain a first rebar rod; a second portion including a second notch formed therein and one or more female portions for receiving and retaining the male portion extending from a corresponding one of the one or more arms, the second notch having a second longitudinal axis that is not parallel to the first longitudinal axis, the second notch being configured to releasably retain a second rebar rod; a chair portion extending outwardly from one or more of the first and second portions; and a hinge portion joining the first and second portions.

Abstract: A spacer for positioning rods and wire in concrete is disclosed. In some embodiments, the spacer includes first and second saddle portions joined together via a connection mechanism. Spacing members are joined with the first and second saddle portions and first and second outer edges are joined with the spacing members opposite the first and second saddle portions. A conforming fixed centering tab having a centering groove is joined with the first saddle portion at first and second ends. An adjustable and conforming centering flap is joined with the second saddle portion at a first end via a hinge connection and includes a free second end opposite the first end. The centering flap has a length greater than a width of an opening of the second saddle portion. The connection mechanism is joined with the spacing members adjacent the outer edges for pivoting the first and second saddle portions.

Abstract: A stackable riser section having a single side wall having a first open end defined by an edge and a second open, channel end. The riser section includes a plurality of bosses extending to the first open end and connected to an interior surface of the sidewall by narrow webs. A channel, on the channel end of one riser is adapted to receive the bosses of a mated riser. A wall defining the boss receiving channel has a plurality of slots with at least a portion defined by parallel edges. The slots receive the webs that connect the bosses to the riser sidewall. The bosses are wider than the portion of the slots defined by the parallel edges. The slotted wall includes thickened wedge portions to snugly fit with the first open end of another riser section. A cover is disclosed that includes the same channel end to coact with the first open end of a riser section.

Abstract: A casting riser pan for defining an access opening in a cast concrete structure, serving as a cast for a cover for closing the access opening, and serving as a seat for the cover. The casting riser pan includes an orientation element for orienting the cover in case of out of round distortion of the casting riser pan and the concrete cover, an inner wall and an outer wall for increased radial strength, and a continuous securement element for attaching the casting riser pan to a casting mold for simultaneously casting the concrete structure and the cover.

Abstract: An orifice shield for distributing water flowing from an orifice in a pipe and preventing blockage of the orifice.
