Abstract

A concrete pathway formwork system, including a formwork panel for forming adjacent concrete panels of a pathway, and a support bracket for supporting the system relative to a ground surface, wherein the formwork panel has a pair of vertically opposed longitudinal rails, and the support bracket has an engagement formation which has an unlocked orientation for inserting the formation between the opposed rails to abut against the formwork panel and a rotated, locked orientation wherein the formation is locked by the rails against lateral withdrawal from the formwork panel.

First claim

1 - 10 . (canceled)

11 . A concrete formwork system for forming adjacent concrete panels on a ground surface, said concrete formwork system comprising:
a formwork panel including a pair of longitudinally extending spaced-apart vertically opposed rails; and a support bracket including an engagement formation insertable between the opposed rails when in an unlocked orientation and thereafter rotatable to a locked orientation relative to the opposed rails such that the engagement formation is locked by the opposed rails against lateral withdrawal from the formwork panel.

12 . The concrete formwork system of claim 11 , wherein when the engagement formation is in the locked orientation, the engagement formation is unlockable from the opposed rails by rotation of the engagement formation about a lateral axis.

13 . The concrete formwork system of claim 11 , which includes a stake engageable with the ground surface, and wherein the support bracket defines an aperture configured to receive the stake.

14 . The concrete formwork system of claim 13 , wherein the stake is threaded.

15 . The concrete formwork system of claim 14 , wherein the threaded stake has opposed faces and the support bracket includes rotationally spaced-apart engagement portions such that the stake is able to be freely slid through the support bracket and is lockable in the support bracket by rotation of the stake about its longitudinal axis relative to the support bracket.

16 . The concrete formwork system of claim 11 , wherein the support bracket terminates above a lower edge of the formwork panel when the engagement formation is in the locked orientation relative to the opposed rails of the formwork panel.

17 . The concrete formwork system of claim 11 , wherein the formwork panel is formed as a unitary part.

18 . The concrete formwork system of claim 11 , wherein the formwork panel includes a pair of longitudinally extending opposed sidewalls, the opposed sidewalls defining a void therebetween.

19 . The concrete formwork system of claim 11 , wherein the support bracket is formed as a unitary part.

20 . The concrete formwork system of claim 11 , wherein the support bracket includes a central rib extending along the length of the support bracket.

21 . A concrete formwork system for forming adjacent concrete panels on a ground surface, said concrete formwork system comprising:
a formwork panel including a pair of longitudinally extending opposed sidewalls and a pair of longitudinally extending spaced-apart vertically opposed rails laterally extending from one of the side walls; a stake engageable with the ground surface; and a support bracket including an engagement formation insertable between the opposed rails and lockable by the opposed rails such that the engagement formation is locked by the opposed rails against lateral withdrawal from the formwork panel, the support bracket defining an aperture configured to receive the stake.

22 . The concrete formwork system of claim 21 , wherein the pair of opposed sidewalls define a void therebetween.

23 . The concrete formwork system of claim 21 , wherein the stake is threaded.

24 . The concrete formwork system of claim 23 , wherein the threaded stake has opposed faces and the support bracket includes rotationally spaced-apart engagement portions such that the stake is able to be freely slid through the support bracket and is lockable in the support bracket by rotation of the stake about its longitudinal axis relative to the support bracket.

25 . The concrete formwork system of claim 21 , wherein the support bracket terminates above a lower edge of the formwork panel when the engagement formation is locked by the opposed rails of the formwork panel.

26 . The concrete formwork system of claim 21 , wherein the formwork panel is formed as a unitary part.

27 . The concrete formwork system of claim 21 , wherein the support bracket is formed as a unitary part.

28 . A concrete formwork system for forming adjacent concrete panels on a ground surface, said concrete formwork system comprising:
a formwork panel including first and second longitudinally extending spaced-apart vertically opposed rails; and a support bracket including an engagement formation having a first edge, a second edge, a third edge, and a fourth edge, the engagement formation insertable between the first and second opposed rails such that the first edge is adjacent to the first rail and the second edge is adjacent to the second rail, and thereafter rotatable to a locked orientation relative to the first and second opposed rails wherein the third edge engages and is held by the first rail and wherein the fourth edge engages and is held by the second rail.

29 . The concrete formwork system of claim 28 , wherein the support bracket terminates above a lower edge of the formwork panel when the engagement formation is in the locked orientation relative to the opposed rails of the formwork panel.

30 . The concrete formwork system of claim 28 , wherein the first edge and the third edge extend at an obtuse angle relative to each other and wherein the second edge and the fourth edge extend at an obtuse angle relative to each other.
