Abstract

A cage spacer for spacing reinforcing rods or welded fabric a specified distance from mold walls for poring concrete during construction projects. The cage spacer comprises two intersection bodies oriented perpendicular to each other and preferable with one body having a base higher than the other. A pair of pads on opposite ends of a first body base for stabilizing the body on the rebar. A pair of rebar engaging clips on opposite ends of the second body base for snapping onto and gripping a perpendicularly intersecting rebar such that the rebar is held securely in the clips. The cage spacer attaches over the intersection of a pair of rebars. At least one apex of the bodies engages a mold wall to keep the mold wall a specified distance from the rebars while concrete is being poured in the mold.

Claims (58)

1. A case spacer comprising:

a first planar body portion having a top and a base and a second planar body portion having a top and a base perpendicular to and bisecting the first planar body,

the first planar body portion base with a pad at each end for engaging rebars,

the second planar body base having a clip portion at each end the clip portion having a rebar engaging portion, arm support segments extending from the rebar engaging portion and opposing arms radially angled toward the center of the rebar engaging portion for capturing a rebar therein attached to the support segments,

the first planar body portion comprises a first trianaular body portion having an apex and a base and the second planar body portion comprises a second triangular body portion having an apex and a base wherein the trianaular body portions intersect on a line which includes both apexes to define an apex axis, the first triangle apex being at a different height than the second triangle apex, the first triagular body portion and second triangular body portion oriented perpendicular to each other, with their bases parallel to a common plane and perpendicular to the apex axis,

the base of the first and second triangular body portions are at different heights to accommodate the position of intersecting rebars,

the base of the second triangular body portion having an aperture therethrough at the intersection of the first base and the second base for allowing a rebar to pass therethrough,

pins adjacent each side of the aperture on the base of the second body portion and extending lower than the base, the pins circumference engages the rebars on a line parallel to the back of the rebar engaging portion to retain the rebars.

2. A cage spacer comprising:

a first planar body portion having a top and a base and a second planar body portion having a top and a base perpendicular to and bisecting the first planar body,

the first planar body portion base with a pad at each end for engaging rebars,

the second planar body base having a clip portion at each end the clip portion having a rebar engaging portion, arm support segments extending from the rebar engaging portion and opposing arms radially angled toward the center of the rebar engaging portion for capturing a rebar therein attached to the support segments,

the first planar body portion comprises a first triangular body portion having an apex and a base and the second planar body portion comprises a second triangular body portion having an apex and a base wherein the triangular body portions intersect on a line which includes both apexes to define an apex axis, the first triangle apex being at a different height than the second triangle apex, the first triangular body portion and second triangular body portion oriented perpendicular to each other, with their bases parallel to a common plane and perpendicular to the apex axis,

the base of the first and second triangular body portions are at different heights to accommodate the position of intersecting rebars,

a pin extending from the apex increases the distance to a mold wall and reduces the footprint of the cage spacer on a mold wall.

3. A cage spacer comprising:

a first planar body portion having a top and a base and a second planar body portion having a top and a base perpendicular to and bisecting the first planar body,

the first planar body portion base with a pad at each end for engaging rebars,

the second planar body base having a clip portion at each end the clip portion having a rebar engaging portion, arm support segments extending from the rebar engaging portion and opposing arms radially angled toward the center of the rebar engaging portion for capturing a rebar therein attached to the support segments,

the first planar body portion comprises a first triangular body portion having an apex and a base and the second planar body portion comprises a second triangular body portion having an apex and a base wherein the triangular body portions intersect on a line which includes both apexes to define an apex axis, the first triangle apex being at a different height than the second triangle apex, the first triangular body portion and second triangular body portion oriented perpendicular to each other, with their bases parallel to a common plane and perpendicular to the apex axis,

the base of the first and second triangular body portions are at different heights to accommodate the position of intersecting rebars,

a feather on the pads reduces the footprint of the cage spacer on a rebar.

4. A cage spacer comprising:

a first planar body portion having a top and a base and a second planar body portion having a top and a base perpendicular to and bisecting the first planar body,

the first planar body portion base with a pad at each end for engaging rebars,

the second planar body base having a clip portion at each end the clip portion having a rebar engaging portion, arm support segments extending from the rebar engaging portion and opposing arms radially angled toward the center of the rebar engaging portion for capturing a rebar therein attached to the support segments,

the first planar body portion comprises a trapezoid body portion having a top and a base and the second planar body portion comprises a double apex body portion having a top and a base wherein the body portions intersect perpendicularly at their centers, and their bases are parallel to a common plane,

the base of the trapezoidal body portion and the double apex portion are at different heights to accommodate the position of intersecting rebars.

5. A cage spacer as in claim 4 wherein,

the rebar engaging portions are oriented parallel to the axis of the intersecting bodies.

6. A cage spacer as in claim 4 wherein,

the rebar engaging portions are oriented perpendicular to the axis of the intersecting bodies.

7. A cage spacer as in claim 4 wherein,

the base of the double apex body portion having an aperture therethrough at the intersection of the double apex body portion for allowing a rebar to pass therethrough.

8. A cage spacer as in claim 7 wherein,

pins adjacent each side of the aperture on the base of the double apex body portion and extending lower than the base, the pins circumference for engaging the rebars on a line parallel to the back of the rebar engaging portion to retain the rebars.

9. A cage spacer as in claim 4 wherein,

a pin extends from the apexes to increase the distance to a mold wall and reduce the footprint of the cage spacer on the mold wall.

10. A cage spacer as in claim 4 wherein,

a feather on the pads reduces the footprint of the cage spacer on a rebar.

11. A cage spacer comprising:

a first planar body portion having a top and a base and a second planar body portion having a top and a base perpendicular to and bisecting the first planar body,

the first planar body portion base with a pad at each end for engaging rebars,

the second planar body base having a clip portion at each end the clip portion having a rebar engaging portion, arm support segments extending from the rebar engaging portion and opposing arms radially angled toward the center of the rebar engaging portion for capturing a rebar therein attached to the support segments,
