Formers and methods of casting bodies, particularly concrete bodies, using the formers

摘要

The invention relates to formers or cores (10) and a method for casting bodies, particularly concrete slabs. The former or core (10) is made from two embossed sheets which are sealed or interconnected together and comprises an array of chambers (20) connected by spacers (30). The former or core (10) can be placed in a mould (60) so that it is incorporated in the cast body. The former or core (10) may be inflatable and supported in the mould (60) by tapered spacer studs (50).
