A form for use in a beam and block flooring system comprises a sheet having a base with two opposed sidewalls projecting therefrom. The walls can be folded so that they are perpendicular with the base. The base has push-out pieces 5 which are used as struts when received in the sidewalls, preferably in slits 7. The ends 8 of the sidewalls preferably conform to the profile of a beam. End walls may be provided, which may also have push-out pieces which can be used as struts. The sidewalls may further comprise an aperture and pre-cut self-closing flap 9 to allow the form to be filed with foam. The sheet material may comprise a corrugated plastics material such as polypropylene. The form may be used in a system further comprising a beam grip and a corrugated or pleated sheet which may sit atop the grip to fill a cavity between beams and blocks with foam. |
