ABSTRACT:
A screed rail for use in the in situ casting of concrete comprising beams forming upper and lower edges of the rail, which are connected by elements extending therebetween. The elements are spaced along the length of the rail to provide for the passage of concrete reinforcement. For this purpose, the spaced elements may form slots, or a breakable web can close the respective spacings, to be broken as required. In an alternative arrangement a screed rail has an overall cross-section with a lower portion defined by parallel sides extending a major distance from the lower edge of the rail. In use, the rail is mounted in shoes to enable the level of the rail to be accurately set.
