## 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.

## Claims

### Claim 1

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.

### Claim 2 (depends on 1)

The adjustable universal clip in accordance with claim 1 wherein said second dovetail channel secured to said base of said first dovetail channel is hingeably secured to said base of said first dovetail channel with said opposing upstanding edges and opposing interior upstanding prongs oriented downwardly, said second dovetail channel hingeably rotated 180 degrees to engage said first dovetail channel.

### Claim 3 (depends on 1)

The adjustable universal clip in accordance with claim 1 wherein said second dovetail channel secured to said base of said first dovetail channel is secured by an elongate flexible hinge arm wherein said second dovetail channel and said opposing edges and said opposing interior upstanding prongs are oriented upwardly, said elongate hingeable arm permitting planar rotation of 180 degrees in order to engage said first dovetail channel.

### Claim 4 (depends on 1)

The adjustable universal clip in accordance with claim 1 wherein said plurality of internal ribs on said exterior threaded tubular cap member are radially oriented within said threaded tubular cap member.

### Claim 5 (depends on 1)

The adjustable universal clip in accordance with claim 1 wherein said plurality of internal ribs within said threaded tubular cap member are non-radial in orientation within said threaded tubular cap member.

### Claim 6 (depends on 1)

The adjustable universal clip in accordance with claim 1 wherein said clip member is rotatably adjustable on said exterior threaded tubular cap member for adjustment of height of said clip member for receipt of a screed guide control joint length of either large profile or small profile.

### Claim 7 (depends on 1)

The adjustable universal clip in accordance with claim 1 wherein said end portion of rebar frictionally engageable with said exterior threaded tubular cap member is supported by a substrate engaging base member, said substate engaging base member having a planar support base having an upper surface and a lower surface there being disposed between said upper and lower surface a plurality of apertures, there being positioned on said upper surface and unitary therewith, a tubular upstanding support tube for the receipt of a lower end of said rebar, said support base secured to said substrate by an adhesive applied to the lower surface of the support base or to the substrate, in a quantity such that sets adhesive flows through said plurality of apertures and adheres to and encapsulates said upper surface of said support plate.

### Claim 8

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.

### Claim 9 (depends on 8)

The improved system in accordance with claim 8 wherein said second dovetail channel secured to said base of said first dovetail channel is hingeably secured to said base of said first dovetail channel with said opposing upstanding edges and opposing interior upstanding prongs oriented downwardly, said second dovetail channel hingeably rotated 180 degrees to engage said first dovetail channel.

### Claim 10 (depends on 8)

The improved system in accordance with claim 8 wherein said second dovetail channel secured to said base of said first dovetail channel is secured by an elongate flexible hinge arm wherein said second dovetail channel and said opposing edges and said opposing interior upstanding prongs are oriented upwardly, said elongate hingeable arm permitting planar rotation of 180 degrees in order to engage said first dovetail channel.

### Claim 11 (depends on 8)

The improved system in accordance with claim 8 wherein said plurality of internal ribs on said exterior threaded tubular cap member are radially oriented within said threaded tubular cap member.
