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, wherein the protection system is provided in modular lengths, and wherein adjacent modular lengths are coupled by one or more bridging pins.

Claims (30)

1. An edge protection system for use with concrete flooring, the edge protection system comprising:

a first edge unit configured to extend in a first longitudinal direction and including a first part couplable to an edge portion of a first concrete flooring panel and a second part couplable to an opposed edge portion of a second concrete flooring panel;

a second edge unit configured to extend in a second longitudinal direction and including a first part couplable to an edge portion of a third concrete flooring panel and a second part couplable to an opposed edge portion of a fourth concrete flooring panel; and

a bridging pin configured to connect the first edge unit and the second edge unit, the bridging pin including a first end portion configured to longitudinally extend in the first longitudinal direction, a second end portion configured to longitudinally extend in the second longitudinal direction, and a center portion connecting the first end portion and the second end portion, the center portion having an outer diameter greater than an outer diameter of the first end portion and greater than an outer diameter of the second end portion.

2. The edge protection system of claim 1 , wherein each of the first part and the second part of the first edge unit and each of the first part and the second part of the second edge unit includes a formwork length and an anchorage length.

3. The edge protection system of claim 2 , wherein each of the first part and the second part of the first edge unit and each of the first part and the second part of the second edge unit includes a plurality of formwork lengths and a plurality of anchorage lengths.

4. The edge protection system of claim 2 , wherein the formwork lengths are each formed of plastic material.

5. The edge protection system of claim 4 , wherein the formwork lengths are each formed of PVC material.

6. The edge protection system of claim 2 , wherein the formwork lengths are each formed as an extrusion.

7. The edge protection system of claim 2 , wherein each formwork length includes a bridging pin securing tab.

8. The edge protection system of claim 2 , wherein each anchorage length is formed of sheet material folded to form a series of spaced apart bridging pin receiving triangular apertures along the anchorage length.

9. The edge protection system of claim 1 , wherein the first end portion of the bridging pin is configured to extend parallel to a longitudinal axis of the first edge unit and the second end portion of the bridging pin is configured to extend parallel to a longitudinal axis of the second edge unit.

10. The edge protection system of claim 1 , wherein the first end portion of the bridging pin is cylindrical and configured to connect to the first edge unit, the second end portion of the bridging pin is cylindrical and configured to connect to the second edge unit, and the center portion of the bridging pin is cylindrical.

11. The edge protection system of claim 10 , wherein the first end portion and the second end portion extend along a same longitudinal axis.

12. The edge protection system of claim 11 , wherein the first concrete flooring panel and the third concrete flooring panel are a same concrete flooring panel.

13. The edge protection system of claim 12 , wherein the first edge unit and the second edge unit extend along transverse longitudinal axes.

14. The edge protection system of claim 1 , wherein the bridging pin is formed of steel.

15. The edge protection system of claim 1 , wherein the bridging pin is formed of plastic.

16. An edge protection system bridging pin for use with an edge protection system for concrete flooring, the edge protection system including a first edge unit and a second edge unit, edge protection system bridging pin comprising:

a first end portion configured to connect to the first edge unit and to longitudinally extend in a first longitudinal direction in which the first edge unit extends;

a second end portion configured to connect to the second edge unit and to longitudinally extend in a second longitudinal direction in which the second edge unit extends; and

a center portion connecting the first end portion and the second end portion, the center portion having an outer diameter greater than an outer diameter of the first end portion and greater than an outer diameter of the second end portion.

17. The edge protection system bridging pin of claim 16 , wherein the first end portion is configured to extend though a triangular aperture formed by the first edge unit, and wherein the second end portion is configured to extend though a triangular aperture formed by the second edge unit.

18. The edge protection system bridging pin of claim 16 , wherein the first end portion and the second end portion extend along a same longitudinal axis.

19. The edge protection system bridging pin of claim 16 , wherein the first end portion and the second end portion extend along transverse longitudinal axes.

20. An edge protection system for use with concrete flooring, the edge protection system comprising:

a first edge unit configured to extend in a first longitudinal direction and including a first part couplable to an edge portion of a first concrete flooring panel and a second part couplable to an opposed edge portion of a second concrete flooring panel;

a second edge unit configured to extend in a second longitudinal direction and including a first part couplable to an edge portion of a third concrete flooring panel and a second part couplable to an opposed edge portion of a fourth concrete flooring panel; and

a bridging pin configured to connect the first edge unit and the second edge unit, the bridging pin including a first end portion configured to longitudinally extend in the first longitudinal direction, a second end portion configured to longitudinally extend in the second longitudinal direction,

wherein the first longitudinal direction is transverse to the second longitudinal direction, and wherein the first end portion of the bridging pin extends transversely to the second end portion of the bridging pin.
