Abstract

A void former comprises a core assembly having at least two body members. The body members are removably coupled together to define the desired shape of a void to be formed in a concrete slab. After the void has been formed in the concrete slab, the body members may be selectively removed from the void.

Claims (3)

1. A void former for forming a void in a concrete slab having an edge defined by a concrete edge form, the void former comprising:

a core assembly including at least two body members removably joined together by an interconnection extending therebetween, said body members having complementary shapes which together define the shape of the void, said body members configured to be selectively separated from said core assembly to thereby facilitate removal of the void former from the void formed in the concrete slab;

said core assembly including at least two substantially parallel concrete engaging outer walls spaced apart to form corresponding parallel surfaces of the void formed in the concrete slab, wherein said body members are hingedly joined together.
