Definitions
- Reinforcement wire enhances the strength and integrity of a concrete structure.
- reinforcement wire is configured into a grid or mesh that is placed within a concrete form. In such cases, the intersections of wires of the mesh may be welded together. If the concrete form is in the shape of a cylinder, the mesh may have a continuous horizontal member wound in a helical configuration and welded to vertical members.
- spacer devices have been used to hold reinforcement wire meshes in place. Some spacers hold the reinforcement wire mesh a specified distance above the ground; these typically have a large ground contact area to form a stable base for holding the reinforcement wire mesh. Other spacers are used for horizontally positioning a reinforcement wire mesh away from form walls. In this case, a large contact area with the form wall will undesirably leave a large area of the spacer exposed when the mold is removed. The concrete is thereby prevented from filling in the volume against the mold wall in the space occupied by the spacer. Thus, a small footprint of the spacers at the mold is desirable so that the edge of the poured concrete has more concrete on the outer surface for greater strength and a better appearance.
- a spacer that connects to a reinforcement wire mesh at an intersection of a first wire and a second wire includes a first triangular body portion and a second triangular body portion, wherein the second triangular body portion is orthogonal to and bisects the first triangular body portion.
- the first triangular body portion includes a first apex, a first base, and a notch on each side of the first triangular body portion proximate each end of the first base, each notch allowing a respective end of the first base to flex toward the first apex.
- the second triangular body portion includes a second apex, a second base, and a clip extending from each end of the second base, each clip configured to surround the second wire.

The first triangular body portion includes a first apex, a first base, and a notch on each side of the first triangular body portion proximate each end of the first base, each notch allowing a respective end of the first base to flex toward the first apex. The second triangular body portion includes a second apex, a second base, and a clip extending from each end of the second base, each clip configured to surround the second wire.
Description
- Reinforcement wire enhances the strength and integrity of a concrete structure. In some cases, reinforcement wire is configured into a grid or mesh that is placed within a concrete form. In such cases, the intersections of wires of the mesh may be welded together. If the concrete form is in the shape of a cylinder, the mesh may have a continuous horizontal member wound in a helical configuration and welded to vertical members.
- It is important to keep the reinforcement wire in a selected position relative to the form. A variety of spacer devices have been used to hold reinforcement wire meshes in place. Some spacers hold the reinforcement wire mesh a specified distance above the ground; these typically have a large ground contact area to form a stable base for holding the reinforcement wire mesh. Other spacers are used for horizontally positioning a reinforcement wire mesh away from form walls. In this case, a large contact area with the form wall will undesirably leave a large area of the spacer exposed when the mold is removed. The concrete is thereby prevented from filling in the volume against the mold wall in the space occupied by the spacer. Thus, a small footprint of the spacers at the mold is desirable so that the edge of the poured concrete has more concrete on the outer surface for greater strength and a better appearance.
- A spacer that connects to a reinforcement wire mesh at an intersection of a first wire and a second wire includes a first triangular body portion and a second triangular body portion, wherein the second triangular body portion is orthogonal to and bisects the first triangular body portion. The first triangular body portion includes a first apex, a first base, and a notch on each side of the first triangular body portion proximate each end of the first base, each notch allowing a respective end of the first base to flex toward the first apex.

A plurality ofspacers 16 is used in an exemplary method to maintain the spacing between reinforcement mesh andexterior form 18. In an exemplary embodiment, an effective height ofspacer 16 results in auniform spacing 22 betweenreinforcement mesh 14 andexterior form 18. In one embodiment,distance 22 is from about 0.75 inch to about 2.0 inches, although other spacer sizes may also be used. -

In an exemplary embodiment,spacer 16 is formed of a lightweight, non-corrosive, resilient and durable material such as a plastic. The resilient characteristics of the material and the C-shaped configuration allow eachclip 30 to securely attach tovertical wire 26.

In an exemplary embodiment,tip 36 is slightly rounded or blunted so as to prevent damage or injury from contact therewith. - In an exemplary embodiment, each
spacer 16 has awide base 38 with theclips 30 for engagingreinforcement wire mesh 14 spaced at the ends of thebase 38 and extending therefrom. This configuration provides stability against twisting forces encountered byspacer 16 when concrete is poured intoform 10.Spacer 16 also has a pair ofpads 32 for engaging a perpendicularly crossingreinforcement wire 28 to stably hold thespacer 16 onreinforcement wire mesh 14. While a contemplated design may includeadditional clips 30 in place ofpads 32, having only one pair ofclips 30 makes it easier and faster to installspacers 16 ontoreinforcement wire mesh 14. - In an exemplary embodiment,
spacer 16 has fouranti-sliding pins 34. This preventsspacer 16 from twisting or turning on thereinforcement wire mesh 14. Becausespacers 16 remain consistently aligned, variations inspacing distance 22 betweenreinforcement wire mesh 14 andexterior form 18 are prevented. - A notch (shown as
