CLOSED VOID FORMER FOR INCLUSION IN CONCRETE SLABS
Void formers or "pods" used to expand masses of poured concrete provide a stiff enclosed body that resists reasonable deforming forces at least until the concrete has become sufficiently solid. The invention uses a minimum of materials in complementary and merged pairs of injection-moulded formed sheets; each pair forming one pod. The formed sheets have projecting, interlocking, spaced-apart formations acting as volume-enclosing elements. The pods replace expanded volume-occupying materials and can be cut down to fit a space. Alternating holes and formations allow the user to lay one sheet partially over another one, so that a given floor surface can be covered without having to cut any one frame apart, thereby minimising time. 200a 211 21K2 ~~t 7KNA' ~~~tA 214 5(4%t - wi 1/8~
