Abstract
An adjustable, universal screed guide/control joint clip for positioning screed guide/control joints utilized in the placement of concrete in concrete slabs, the adjustable universal screed guide clip allowing for the exact adjustment of the height of the screed guide attached thereto for the placement of the concrete slabs, the adjustable universal screed guide clip allowing the installation of the screed guide in applications heretofore not allowable, the adjustable, universal screed guide/control joint clip capable of accommodating both large and small profile screed guides.
Claims14
An adjustable, universal clip for positioning and leveling a large profile or small profile screed guide/control joint for the placement of concrete, said screed guide/control joint formed of extruded polymer and having a base, an upward standing ridge of triangular cross section terminating in an upper linear edge, said adjustable, universal clip comprising:
- an exterior threaded tubular cap member having a plurality of internal ribs, said exterior threaded cap member frictionally engageable with an upstanding end portion of rebar positioned in a substrate;
- a clip member having a tubular base having an internal thread rotatable engageable with said exterior threaded cap member, said tubular base having a unitarily formed first dove tail channel formed on an upper surface, said first dove tail channel formed of a base and opposing upstanding edges defining said dove tail channel, said dove tail channel dimensioned to snap fittingly receive a base of a large profile screed guide/control joint;
- a second dove tail channel secured to said base of said first dove tail channel, said second dove tail channel having a base and opposing upstanding edges snap fittingly engageable in said first dove tail channel, said second dove tail channel having opposing interior upstanding prongs dimensioned to snap fittingly receive a small profile screed guide/control joint;
- a plurality of said exterior threaded tubular cap members, upstanding end portions of said rebar, and said clip members arranged in a linear orientation to a substrate in order to snap fittingly receive a screed guide/control joint length of either large profile or small profile.
An improved system for positioning and leveling a large profile or small profile screed guide/control joint for the placement of concrete on any type of substrate, said screed guide/control joint formed of extruded polymer and having a base, an upward standing ridge of triangular cross section terminating in an upper linear edge, the system comprising:
- a. positioning upstanding pieces of rebar in an aligned orientation in the substrate to be overlaid with concrete;
- b. positioning an exteriorly threaded tubular cap member having a plurality of internal ribs in frictional engagement with the upper portion of said upstanding piece of rebar;
- c. securing a clip member to said exteriorly threaded tubular cap member, said clip member having a tubular base having an internal thread rotatably engageable with said exterior threaded cap member, said tubular base having a unitarily formed first dovetail channel formed on an upper surface thereof, said first dovetail channel formed of a base and opposing upstanding edges defining said dovetail channel, said dovetail channel dimensioned to snap fittingly receive a base of a large profile screed guide/control joint, said clip member having a second dovetail channel secured to said base of said first dovetail channel, said second dovetail channel having a base and opposing upstanding edges snap-fittingly engageable in said first dovetail channel, said second dovetail channel having opposing interior upstanding prongs dimensioned to snap-fittingly receive a small profile screed guide/control joint;
- d. rotating said clip member on said exteriorly threaded tubular cap member to achieve equivalent heights of all said clip members secured to said exterior threaded tubular cap members on said pieces of rebar;
- e. snap fitting said base of said screed guide/control joint into said plurality of aligned and leveled clip members;
- and
- f. placement of said concrete onto said substrate to the height of said upper linear edge of said screed guide/control joint.
