SCREED RAIL APPARATUS

摘要

Leave-in-place screed rail apparatus for defining the edges of concrete floor slabs and including two or more substantially vertically-disposed elongate members joined together with yieldable connections, in which the yieldable connections comprise a blind rivet including a cylindrical shell in which is carried a rivet stem, in combination with a flanged collar against which the rivet is set, either the shell of the rivet and/or the flanged collar yielding under tensile forces generated as the concrete of the slabs cures in use to allow the elongate members to separate smoothly and non- incrementally.
