Supporting frame for a manhole or similar access cover

support frame 3, for an access cover (e.g. an iron framework as illustrated), has an outer downwardly facing flange 6, an inner downwardly facing flange 5 and an upper web 7 connecting the outer to the inner flange. The outer flange has at least one aperture and/or recess 12 which will allow concrete slurry to pass therethrough. The frame member may be internally reinforced by internal webbing extending downwardly from the upper web and connecting at least a portion of the inner surface of the outer flange to at least a portion of the inner surface of the inner flange. The upper web may have at least one aperture 9 which will allow concrete slurry to pass therethrough. support frame 3, for an access cover (e.g. an iron framework as illustrated), has an outer downwardly facing flange 6, an inner downwardly facing flange 5 and an upper web 7 connecting the outer to the inner flange.
