Abstract

A pair of metal angle sections (100, 101) are held together in abutting face to face relationship. They are supported on bar chairs to function as a screed rail during pouring of a concrete floor. Each angle section has a vertical limb (110, 110A), an upper horizontal portion (111, 112), and an aperture flange (114), to assist it in keying it into the concrete. The flange (114) is stepped down below the plane of the horizontal portions (111, 112), and hence below the surface of the concrete. During curing of the concrete, the abutting limbs (110, 110A) move apart to induce the formation of a crack. This also provides a reinforced corner edge along the line of the crack.
