Concrete formwork brace and method of bracing concrete formwork

Abstract

A concrete formwork brace having a base, a bracket configured to support a concrete formwork and a pair of adjustable arms. A first length adjustable arm is connected to the base and the bracket and a second arm is connected to the base and the bracket. The connection between the first arm and the base is vertically offset from the connection between the second arm and the base and the connection between the first arm and the bracket is vertically offset from the connection between the second arm and the bracket. The first arm is length adjustable such as to adjust the orientation of the bracket.

 a base,   a bracket configured to support a concrete formwork,   a first length adjustable arm, connected to the base and the bracket, and   a second arm connected to the base and the bracket;   wherein the connection between the first arm and the base is vertically offset from the connection between the second arm and the base,   wherein the connection between the first arm and the bracket is vertically offset from the connection between the second arm and the bracket; and   wherein the first arm is length adjustable such as to adjust the orientation of the bracket.   
     
     
         2 . The concrete formwork brace of  claim 1 , wherein the second arm is length adjustable. 
     
     
         3 . The concrete formwork brace of  claim 1  wherein the connection between the first arm and the base is horizontally offset from the connection between the second arm and the base. 
     
     
         4 . The concrete formwork brace of  claim 1  wherein the connection between the first arm and the base is at a first end of the base and the connection between the second arm and the base is at an intermediate position between the first end of the base and a second end of the base. 
     
     
         5 . The concrete formwork brace of  claim 4  wherein the connection between the second arm and the base is centrally located on the base. 
     
     
         6 . The concrete formwork brace of  claim 1  wherein the connection between the second arm and the base is vertically elevated relative to the connection between the first arm and the base. 
     
     
         7 . The concrete formwork brace of  claim 1  wherein the base has mounting features for securing the base to a ground surface. 
     
     
         8 . The concrete formwork brace of  claim 7  wherein the mounting features are apertures configured to receive fasteners for securing the base to a ground surface. 
     
     
         9 . The concrete formwork brace of  claim 1  wherein the bracket has mounting features for securing the bracket to formwork. 
     
     
         10 . The concrete formwork brace of  claim 9  wherein the bracket has apertures configured to receive fasteners securing the bracket to formwork 
     
     
         11 . The concrete formwork brace of  claim 1  wherein the bracket is configured to rest, in use, on a ground surface. 
     
     
         12 . The concrete formwork brace of  claim 1  wherein the bracket is height-adjustable. 
     
     
         13 . The concrete formwork brace of  claim 1  wherein the brace includes a level indicator. 
     
     
         14 . The concrete formwork brace of  claim 1 , wherein the first length adjustable arm is length-adjustable by rotation of a threaded element. 
     
     
         15 . The concrete formwork brace of  claim 2 , wherein the second arm is length-adjustable by rotation of a threaded element. 
     
     
         16 . The concrete formwork brace of  claim 1  wherein the connection between the first arm and the bracket is a pivotal connection and the connection between the second arm and the bracket is a pivotal connection. 
     
     
         17 . The concrete formwork brace of  claim 1  wherein the connection between the first arm and the base is a pivotal connection and the connection between the second arm and the base is a pivotal connection. 
     
     
         18 . A concrete formwork brace as claimed in  claim 1  wherein the bracket includes a first engagement element configured to engage with a cooperating second engagement element on a concrete formwork to define a releasable connection between the bracket and the formwork. 
     
     
         19 . The concrete formwork brace of  claim 18  wherein the releasable connection is a clamp connection. 
     
     
         20 . The concrete formwork brace of  claim 18  wherein the releasable connection is a hook connection.
