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, and a support foot for supporting the system relative to a ground surface, wherein the first part has a pair of vertically opposed longitudinal rails, and the support foot has an engagement formation which has an unlocked orientation for inserting the formation between the opposed rails to abut against the first part and a rotated, locked orientation wherein the formation is locked by the rails against lateral withdrawal from the first 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 including a first pair of opposed longitudinal rails;
a second part couplable to an opposed edge portion of an adjacent second concrete flooring panel; and
a first support foot including a first engagement formation configured to be in an unlocked orientation that enables insertion of the first engagement formation between the first pair of opposed rails, and configured to be in a rotated locked orientation such that the first engagement formation is locked by the first pair of opposed rails against lateral withdrawal from the first part, the first engagement formation including a locking rib,
a stake having threads and opposing unthreaded surfaces separating parts of the threads, the stake being insertable into the first engagement formation and being rotatable in the first engagement formation to cause the threads of the stake to engage the locking rib to lock the stake in the first engagement formation, and a first footing threadedly couplable to the stake such that the stake enables adjustment of a height of the first footing relative to the first engagement formation.

2. The edge protection system of claim 1 , wherein the second part includes a second pair of opposed longitudinal rails, and which includes a second support foot including a second engagement formation configured to be in an unlocked orientation that enables insertion of the second engagement formation between the second pair of opposed rails, and configured to be in a rotated locked orientation such that the second engagement formation is locked by the second pair of opposed rails against lateral withdrawal from the second part.

3. The edge protection system of claim 2 , wherein the first engagement formation is unlockable from the first pair of opposed rails by rotation of the first engagement formation about a first lateral axis from the locked orientation to the unlocked orientation.

4. The edge protection system of claim 3 , wherein the second engagement formation is unlockable from the second pair of opposed rails by rotation of the second engagement formation about a second lateral axis from the locked orientation to the unlocked orientation.

5. The edge protection system of claim 1 , wherein the first engagement formation is-includes a support plate having diagonally opposed truncated corners.

6. The edge protection system of claim 5 , wherein the first engagement formation includes a trapezoid support plate.

7. The edge protection system of claim 1 , wherein the first engagement formation includes a trapezoid support plate.

8. The edge protection system of claim 1 , wherein the first footing is threadably attachable to the stake.

9. An edge protection system support foot for an edge protection system for use with concrete flooring, the edge protection system support foot comprising:
an engagement formation configured to be in an unlocked orientation that enables insertion of the engagement formation between a first pair of opposed rails of a first part of the edge protection system, wherein the first part is couplable to an edge portion of a first concrete flooring panel, and configured to be in a rotated locked orientation such that the engagement formation is locked by the opposed rails against lateral withdrawal from the first part, wherein the engagement formation includes a support plate having diagonally opposed truncated corners, the engagement formation including a locking rib;
a stake having threads and opposing unthreaded surfaces separating parts of the threads, the stake being insertable into the engagement formation and being rotatable in the engagement formation to cause the threads of the stake to engage the locking rib to lock the stake in the engagement formation; and
a footing attachable to the stake.

10. The edge protection system support foot of claim 9 , wherein the engagement formation is unlockable from the first pair of opposed rails by rotation of the engagement formation about a lateral axis from the locked orientation to the unlocked orientation.

11. The edge protection system of claim 9 , wherein the first footing is threadedly couplable to stake.

12. 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 including a first pair of opposed longitudinal rails;
a second part couplable to an opposed edge portion of an adjacent second concrete flooring panel; and
a first support foot including a first engagement formation configured to be in an unlocked orientation that enables insertion of the first engagement formation between the first pair of opposed rails, and configured to be in a rotated locked orientation such that the first engagement formation is locked by the first pair of opposed rails against lateral withdrawal from the first part, wherein the first engagement formation includes a support plate having diagonally opposed truncated corners, the first engagement formation including a locking rib, and
a stake having threads and opposing unthreaded surfaces separating parts of the threads, the stake being insertable into the first engagement formation and being rotatable in the first engagement formation to cause the threads of the stake to engage the locking rib to lock the stake in the first engagement formation.

13. An edge protection system support foot for an edge protection system for use with concrete flooring, the edge protection system support foot comprising:
an engagement formation configured to be in an unlocked orientation that enables insertion of the engagement formation between a first pair of opposed rails of a first part of the edge protection system, wherein the first part is couplable to an edge portion of a first concrete flooring panel, and configured to be in a rotated locked orientation such that the engagement formation is locked by the opposed rails against lateral withdrawal from the first part, wherein the engagement formation includes a trapezoid support plate, the engagement formation including a locking rib;
a stake having threads and opposing unthreaded surfaces separating parts of the threads, the stake being insertable into the engagement formation and being rotatable in the engagement formation to cause the threads of the stake to engage the locking rib to lock the stake in the engagement formation; and
a footing attachable to the stake.
