| 20090158682 | Screed Rail - A screed rail comprises first and second elongate plate members arranged in face-to-face configuration, the first plate member being attached to leg members by height-adjustable lock means and the second plate member being attached to the first plate member by frangible joining means with the upper edges of the plate members in registration. The second plate member is attached only to the first plate member and the first plate member is attached to the leg members and by independent frangible connections to the second plate member whereby the plate members can separate laterally as the concrete cures without the attachment of the leg members inhibiting movement of the second plate member relative to the first. | 06-25-2009 |
