<p>Rails (2) pre-mounted on their tie plates (11) are suspended above the location at which a concrete slab is to be poured. The position of the rails is then adjusted to move the bottom plate of temporary tie plates, disposed under the base of each tie plate, accurately to the location at which the tie plates must rest. Concrete slab is then poured up to the height of the temporary tie plates. <??>The rails are raised, after which the temporary tie plates are removed. The rails are then positioned on the slab, with the tie plates fixed to the corresponding anchor members. An Independent claim is also included for a temporary tie plate.</p> |
