The parapet, primarily for use alongside roads and other transportation infrastructure links at bridges, adjacent steep inclines etc., comprises a number of uprights 12 upon which at least one rail 16 is supported, with the rail being connected to the upright via a bracket 20a formed from an annular section that is attached on one side to an upright and on the other to the rail. The annulus is preferably a box-section with a length less than its width and which is designed to be attached with bolts that extend through preformed apertures. One or more of the apertures may be elongate and two of the apertures may extend in mutually transverse directions. The length of the bracket may be greater on one side than the other, with the shorter side preferably being adjacent to the rail. The parapet is preferably formed from steel which may be galvanised. Also claimed is a parapet where the bracket comprises an upwardly aligned annular section that includes a shelf extending from the rear to the front of the annulus. |
