Abstract

An edge protection system for use with concrete flooring, including a first part for coupling to an edge portion of a first concrete flooring panel and a second part for coupling to an opposed edge portion of a second, neighbouring, concrete flooring panel, a dowel plate and a dowel sheath, wherein the dowel plate is for supporting the second concrete flooring panel relative to the first concrete flooring panel, the dowel sheath is fitted to extend laterally from the first part, with an internal cavity of the dowel sheath aligning with apertures formed in the first and second parts such that the dowel plate is able to be inserted into the dowel sheath cavity through said apertures to a supporting position in which the dowel plate remains in the apertures and extends laterally from the second part.

First claim

The invention claimed is:

1. An edge protection system for use with concrete flooring, the edge protection system comprising:
a first part couplable to an edge portion of a first concrete flooring panel, the first part defining a first dowel receiving aperture;
a second part couplable to an opposed edge portion of an adjacent second concrete flooring panel, the second part defining a second dowel receiving aperture; and
a dowel sheath couplable to the first part, the dowel sheath configured to extend laterally outwardly from the first part, wherein the dowel sheath is configured to receive a dowel plate prior to formation of the second concrete flooring panel, and wherein the dowel sheath defines an internal cavity configured to align with the first dowel receiving aperture defined by the first part and to align with the second dowel receiving aperture defined by the second part such that the dowel plate is insertable through the second dowel receiving aperture and then the first dowel receiving aperture into the internal cavity to a supporting position in which the dowel plate remains in the second dowel receiving aperture, remains in the first dowel receiving aperture, and extends laterally from the second part, wherein the dowel sheath includes at least one clip configured to engage a first edge of the first part that partially forms the first dowel receiving aperture in the first part and a second edge of the second part that partially form the second dowel receiving aperture in the second part.

2. The edge protection system of claim 1 , wherein the first dowel receiving aperture formed in the first part and the second dowel receiving aperture formed in the second part are each slots.

3. The edge protection system of claim 1 , wherein the dowel sheath includes a plurality of clips configured to engage the first edge of the first part that partially forms the first dowel receiving aperture in the first part and the second edge of the second part that partially form the second dowel receiving aperture in the second part.

4. The edge protection system of claim 1 , wherein the at least one clip is configured to engage a first bottom edge of the first part that partially forms the first dowel receiving aperture in the first part and a second bottom edge of the second part that partially forms the second dowel receiving aperture in the second part.

5. The edge protection system of claim 1 , wherein the dowel sheath includes a plurality of spaced apart clips each configured to engage the first edge of the first part that partially forms the first dowel receiving aperture in the first part and the second edge of the second part that partially forms the second dowel receiving aperture in the second part.

6. The edge protection system of claim 1 , wherein the dowel sheath includes a top wall, a bottom wall, a first side wall, a second side wall, a front plate attached to the top wall, the bottom wall, the first side wall, and the second side wall, wherein the front plate is configured to engage an outer surface of the first part, and wherein the dowel sheath includes a first part engagement brace extending from and above the top wall and above the front plate.

7. An edge protection system dowel sheath for use with and edge protection system for concrete flooring, the edge protection system dowel sheath comprising:
a top wall;
a bottom wall;
a first side wall;
a second side wall;
at least one clip configured to engage a first edge of a first part couplable to an edge portion of a first concrete flooring panel, the first edge partially defining a first dowel receiving aperture in the first part, and configured to engage a second edge of a second part couplable to an edge portion of a second concrete flooring panel, the second edge partially defining a second dowel receiving aperture in the second part; and
a front plate attached to the top wall, the bottom wall, the first side wall, and the second side wall, wherein the front plate is configured to engage an outer surface of a first part, and
wherein the top wall, the bottom wall, the first side wall, and the second side wall define an internal cavity configured to receive a dowel plate prior to formation of the second concrete flooring panel, and wherein the internal cavity is configured to align with the first dowel receiving aperture formed in the first part and the second dowel receiving aperture formed in the second part such that the dowel plate is insertable into the internal cavity through the first and second dowel receiving apertures to a supporting position in which the dowel plate remains in the first and second dowel receiving apertures and extends laterally from the second part.

8. The edge protection system dowel sheath of claim 7 , wherein the first dowel receiving aperture formed in the first part and the second dowel receiving aperture formed in the second part are each slots.

9. The edge protection system dowel sheath of claim 7 , which includes a plurality of spaced apart clips each configured to engage the first edge of the first part that partially forms the first dowel receiving aperture in the first part and the second edge of the second part that partially forms the second dowel receiving aperture in the second part.

10. The edge protection system dowel sheath of claim 7 , which includes a first part engagement brace extending from and above the top wall and above the front plate.

11. An edge protection system for use with concrete flooring, the edge protection system comprising:
a first part couplable to an edge portion of a first concrete flooring panel, the first part defining a first dowel receiving aperture;
a second part couplable to an opposed edge portion of an adjacent second concrete flooring panel, the second part defining a second dowel receiving aperture; and
a dowel sheath couplable to the first part, the dowel sheath configured to extend laterally outwardly from the first part, wherein the dowel sheath is configured to receive a dowel plate prior to formation of the second concrete flooring panel, and wherein the dowel sheath defines an internal cavity configured to align with the first dowel receiving aperture defined by the first part and to align with the second dowel receiving aperture defined by the second part such that the dowel plate is insertable through the second dowel receiving aperture, through the first dowel receiving aperture, and into the internal cavity to a supporting position in which the dowel plate remains in the second dowel receiving aperture, remains in the first dowel receiving aperture, and extends laterally from the second part, wherein the dowel sheath includes at least one clip configured to engage a first bottom edge of the first part that partially forms the first dowel receiving aperture in the first part and a second bottom edge of the second part that partially forms the second dowel receiving aperture in the second part.
