Rebar spacer assembly

In a spacer assembly for use in construction applications for supporting reinforcement bar members relative to a supporting surface for concrete construction, the combination comprising:

• a spacer member configured for positioning relative to the supporting surface, said spacer member having saddle means for receiving a reinforcement bar member at least partially thereon;
• a unitary clamp member, said clamp member including a first generally U-shaped portion with a bight portion and first and second leg portions;
• coacting means on said clamp member and said spacer member for attaching said clamp member to said spacer member adjacent said saddle means, said clamp member including fist means for fastening a first bar member at least partially within said saddle means, and second means for fastening a second bar member to said spacer member in intersecting relation to and atop said first bar member, and wherein said coacting means includes first and second slot means in said spacer member for receiving said leg portions.

In a spacer assembly for use in construction application for supporting reinforcement bar member relative to a supporting surface for concrete construction, the combination comprising:

• a spacer member configured for positioning relative to the supporting surface, said spacer member including a support post portion and having saddle means formed in a surface of said post portion for receiving a reinforcement bar member at least partially thereon;
• a unitary clamp member including a first generally U-shaped portion with a bight portion and first and second leg portions;
• coacting means on said clamp member and siad spacer member for attaching said clamp member to said spacer member adjacent said saddle means, said coacting means including aperture means extending through said post portion for receiving said leg portions insertion through said aperture means, said clamp member including first means for fastening a first bar member at least partially within said saddle means, and second means for fastening a second bar member to said spacer member in intersecting relation to and atop said first bar member.

In a spacer assembly for use in construction applications for supporting reinforcement bar members relative to a supporting surface for concrete construction, the combination comprising:

• a unitary clamp member having first and second spaced leg portions;
• a spacer member configured for positioning relative to the supporting surface, said spacer member including a support post portion and having saddle means formed in a surface of said post portion for receiving a reinforcement bar member at least partially thereon, and wherein said spacer member includes aperture means extending through a surface including said saddle means;
• coacting means on said clamp member and said spacer member for attaching said clamp member to said spacer member adjacent said saddle means, said clamp member including first means for fastening a first bar member at least partially within said saddle means, and second means for fastening a second bar member to said spacer member in intersecting relation to and atop said first bar member, and wherein said coacting means includes tang arm means in proximate relation to said aperture means and serrations on said leg portions for detentingly engaging said tang arm means upon insertion of said leg portions into said aperture means.

The spacer member according to clamp 12 wherein said extender member is one of a plurality of extender members, each of said extender members having a different predetermined distance between said first and second surfaces thereof.

The spacer assembly according to clamp 12 wherein said coacting means on said member and said spacer member includes aperture means in said spacer member and arm members on said clamp member, said arm members including projections thereon for engagement with the periphery of said aperture means on insertion of said arm members therethrough.

The spacer assembly according to clamp 17 wherein said extender member includes opeinings in alignment with said slot means of said spacer member for enabling passage of the legs therethrough.

In a spacer assembly for use in construction applications for supporting reinforcement bar members relative to a supporting surface for concrete construction, wherein the spacer member is configured for positioning on a supporting surface for receiving a reinforcement bar member at least partially thereon within a saddle means a fixed distance from the supporting surface, with the bar member retained on the spacer by a clamp member having leg portions frictionally engaging slot means in the spacer member adjacent the saddle means, the improvement comprising:

• an extender member having a first surface configured for mating coacting engagement with the saddle means of said spacer member, and a second displaced surface a predetermined distance from said first surface, said second surface having generally identically configured saddle means, said extender member being configured for permitting the leg portions of said clamp member to frictionally engage the slot means in the spacer member for retaining a bar member within the saddle means of said extender member with said extender member within the saddle means of said spacer member.
