Retainer clip for reinforcement of concrete walls

A retainer clip assembly for retention of a reinforcing rod comprising a retainer clip and a notched form tie which has a generally rectangular cross section and a notch said retainer clip comprising a one-piece body having:

• a header;
• and
• first and second clips extending angularly from the header, spaced apart in a first direction, and defining therebetween a generally u-shaped opening sized to slidably receive a reinforcing rod of generally circular cross section;
• and
• wherein each of said clips further comprises first and second prongs of different lengths spaced apart in directions lateral to said first direction, at least two prongs of said clips further defining therebetween a narrow generally rectangular passage extending generally through the clips in the first direction, said passage intersecting at least a portion of said u-shaped opening and sized to receive at least said notched form tie;
• wherein said u-shaped opening extends further into said header than does said narrow generally rectangular passage;
• and
• wherein at least one of said first and second prongs of each said clip is flexible;
• and
• wherein at least one of said first and second prongs of each said clip has a catch positioned in spaced relationship from said header to releasably confine said form tie received in the narrow generally rectangular passage when said reinforcing rod is positioned in said notch of the form tie and received in said u-shaped opening between the form tie and said header;
• wherein, without clamping, the retainer clip assembly secures said reinforcing rod in position substantially against the form tie to inhibit both relative motion of the form tie in the first direction and substantial separation between the reinforcing rod and retainer clip assembly.

A retainer clip assembly for retention of a reinforcing rod comprising a retainer clip and a notched form tie which has a generally rectangular cross section and a notch said retainer clip comprising a one-piece body having:

• a header;
• first and second clips extending angularly from the header to clip ends, said clips in generally parallel relationship, spaced apart in a first direction, and defining therebetween a generally u-shaped opening sized to slidably receive a reinforcing rod of generally circular cross section, said header having a semicircular portion defining the closed end of said u-shaped opening;
• and
• wherein each of said clips further comprises first and second prongs spaced apart in directions lateral to said first direction, at least two prongs of said clips further defining therebetween a narrow generally rectangular passage extending generally through the clips in the first direction, said passage intersecting at least a portion of said u-shaped opening and sized to receive said notched form tie;
• wherein the ratio between the width of said generally u-shaped opening defined by the first and second clips, and the width of said narrow generally rectangular passage defined by the at least two prongs is greater than or equal to 2:1;
• wherein the end of at least one of said clips opposite the header is beveled;
• and
• wherein in each of said clips:
• at least one of said prongs has flexibility to deflect and facilitate receipt of said notched form tie in said narrow generally rectangular passage by slidably inserting the form tie towards said header between said ends of said clips;
• and
• at least one of said clips has a catch positioned near the end thereof opposite said header such that said clips releasably confine said generally rectangular notched form tie received in the narrow generally rectangular passage when said reinforcing rod is positioned in a notch of the form tie and received in said u-shaped opening between the form tie and said header;
• wherein, without clamping, in said retainer clip assembly the retainer clip secures said reinforcing rod in position substantially against the form tie to inhibit both relative motion in the first direction and substantial separation between said reinforcing rod and said form tie.
