Claim Text:
1. A self-climbing scaffold system comprising: a rail having a lower section and an upper end; a first shoe through which the lower section of the rail is threaded, the first shoe anchored to a first concrete section having a first facing wall, a second shoe anchored to a second concrete section having a second facing wall, the second concrete section being located vertically above the first concrete section; and a guide element coupled with the upper end of the rail and having a first flange section configured to be threaded through the second shoe, the first flange section having an outer guide surface facing the second facing wall that is configured to engage with at least a portion of the second shoe to vertically straighten the rail with respect to the second shoe when the first flange section is vertically threaded through the second shoe, the outer guide surface being rotatable towards and away from the second facing wall between first and second angular positions, the guide element comprising a hole that extends through the guide element, a first coupling element extending through the hole pivotally couples the guide element to a portion of the self-climbing scaffold system at a location at or near the upper end of the rail, the guide element including an elongate curved slot that extends through the guide element and that is spaced a distance away from the hole, the elongate curved slot cooperates with a second coupling element that extends through the elongate curved slot to delimit rotation of the outer surface of the guide element between the first and second angular positions; and a connecting element that connects the upper end of the rail to a horizontal guide, a major length of the horizontal guide arranged substantially orthogonal to a major length of the rail, the connecting element having a hole corresponding with the hole of the guide element, the guide element pivotally coupled to the connecting element by the first coupling element extending through the hole of the connecting element and the hole of the guide element, and the second coupling element extends from or through the connecting element.
