<p>The wall cassette comprising a pair of opposing, substantially parallel wall panels 1 having a void 3 therebetween. The wall panels are connected together in spaced apart relation by means of at least one cross tie 2 that extends across said void and comprises an elongate connector having a generally central opening. The method comprises the steps of providing at least first 5a and second 6 rebar assemblies. Each of said rebar assemblies comprising a pair of rebar rods connected together substantially in parallel and in spaced apart relation by means of at least one rigid spacer device 8. The first rebar assembly is inserted via an open end of said wall cassette, through an opening in a cross tie such that said rebar rods are substantially parallel to said wall panels. The second rebar assembly is inserted(6) through a second open end of said wall cassette and over said cross tie opening. The second open end being substantially orthogonal to said first open end, such that the longitudinal edges of said second rebar assembly abut said first rebar assembly and prevent movement thereof relative to each other within said cross tie opening.</p> |
