Corner shutter member
A corner shutter member for retaining a settable material comprises a sheet of material shaped and folded to define an upright retaining wall. The retaining wall has a line of weakness 21 extending vertically across it to define first and second retaining wall portions 28a/b. Each of the first and second portions has a respective first or second base portion 29a/b extending orthogonally from a lower edge to keep the retaining wall substantially upright. The shutter member is bent on site to form either an internal or external corner, and the base portions are shaped so as to not obstruct each other. The first and second portions may have an orthogonal lip portion 30a/b extending from an upper edge to resist distortion. The shutter members may be transported flat. A plurality of ties 33 may link the base portions to corresponding wall portions and may be stamped or cut into the portions. The line of weakness may be a row of apertures or may be thinner than the rest of the shutter member. Also claimed is a method of forming a concrete slab by folding a shutter member and pouring concrete over the base portions.
