Attorney, Agent or FirmInternational ClassE04G 017/06AbstractA concrete forms wall spacer is provided in the configuration of a truss having top and bottom horizontal frame members interconnected by angularly extending reinforcing struts. The top frame member is configured to rest upon the upper edges of a pair of spaced concrete form walls, and end portions of the top frame member are extended downward for abutment by the outer sides of the spaced concrete form walls, to define the desired spacing between the walls. Supported by the bottom frame member are a pair of spaced clip members each configured to removably support a pair of lengths of rebar which extend horizontally in opposite directions to other longitudinally spaced form wall spacers. A pair of vertically spaced rebar supports are mounted on the top and bottom frame members for frictionally securing a vertically extending length of rebar for forming a structural tie between a concrete footing and a vertically extending concrete wall. In a second embodiment of the invention, a plurality of pairs of vertically spaced rebar supports for vertical rebar are provided as detachable components.Field of SearchWith transverse tieTransverse, disparate material form member Dissimilar material member in section Spacer-positioner; e.g., rebar chair Crossed supported member type Plural feet or seat Sheet form with tabs oppositely extending from base sheet Cable suspension clamps Clamped to mounting surface by resilient clip Clamped to mounting surface by resilient clip By resilient clip Clip REINFORCEMENT STRUCTURE PER SE With road chair ROAD CHAIR PER SE | |
