Abstract: A connector for securing reinforcing rod elements to an adjacent spaced formwork panel, the connector including: a compression resistant spacer element having a first end and a second end defining a depth there between; one or more securing flanges extending from said first end for securing the connector to a formwork panel, and reinforcing rod retention means extending from said second end.

Abstract: The invention relates to an apparatus and method for moulding a substantially hollow building panel (12) of the kind having spaced opposed outer panel walls (14) interconnected by a plurality of spaced formations 16 such that adjacent formations each define a void (18) therebetween. The apparatus including a mould (20) having means to define an outer surface of least one of the outer panel walls and a plurality of spaced apart inflatable void forming plug members (26) connectable with an inflation means, disposed within the mould. The apparatus further including a means to introduce a settable wet mix into the mould.

Abstract: An apparatus and method for molding a substantially hollow building panel of the kind having spaced opposed outer panel walls interconnected by a plurality of spaced formations such that adjacent formations each define a void therebetween. The apparatus includes a mold having means to define an outer surface of at least one of the outer panel walls and a plurality of spaced apart inflatable void forming plug members connectable with an inflation means, disposed within the mold. The apparatus further includes a means to introduce a settable wet mix into the mold.
