Track-guided self-climbing shuttering system with climbing rail extension pieces

Abstract

In a rail-guided self-climbing formwork system 10 in the building sector, climbing rails 18 are guided in climbing shoes 24, 26, 34, 36, wherein the climbing rails are integrated into a scaffold unit. The scaffold unit also includes a working platform 12 and a finishing platform 16, which are also attached to the climbing rails 18. Climbing rail extension pieces 20, 22 can be mounted on the free ends of the climbing rails 18 and rigidly attached thereto. The climbing rail extension pieces 20, 22 are shorter in length than the climbing rails 18.

1 - 8 . (canceled) 
     
     
         9 . A concrete section with a rail-guided self-climbing formwork system in the building sector, the section comprising:
 climbing shoes attached to a hardened concrete section;   climbing rails, guided in said climbing shoes, said climbing rails being integrated into a scaffold unit, each climbing rail being guided and held in a movable manner in multiple said climbing shoes, wherein each climbing rail has a length which corresponds to a height of the concrete section; and   climbing rail extension pieces, said extension pieces being attached to free ends of said climbing rails, each extension piece having a length which is shorter than a length of said climbing rails, wherein said climbing rail extension pieces are attached to lower free ends of said climbing rails in a detachable and/or pivoting manner.   
     
     
         10 . The concrete section with a rail-guided self-climbing formwork system of  claim 9 , wherein said length of said climbing rail extension pieces is greater than or equal to half a distance between two climbing shoes, arranged directly on top of each other. 
     
     
         11 . The concrete section with a rail-guided self-climbing formwork system of  claim 9 , wherein said climbing rail extension pieces are connected to said free ends of said climbing rails by means of locking pins. 
     
     
         12 . The concrete section with a rail-guided self-climbing formwork system of  claim 11 , wherein said climbing rail extension piece is connected to said free end of said climbing rail by means of two locking pins. 
     
     
         13 . The concrete section with a rail-guided self-climbing formwork system of  claim 9 , wherein said climbing rails as well as fixed climbing rail extension pieces are assembled from two profile rails which are held together at a separation from each other by means of supporting pins and/or spacers and connecting pins. 
     
     
         14 . The concrete section with a rail-guided self-climbing formwork system of  claim 9 , wherein said scaffold unit has a working platform and a finishing platform. 
     
     
         15 . The concrete section with a rail-guided self-climbing formwork system of  claim 14 , wherein said working platform is structured to support an external and internal formwork which can be moved on said working platform. 
     
     
         16 . The concrete section with a rail-guided self-climbing formwork system of  claim 9 , wherein lower free ends of fixed climbing rail extension pieces, which are connected in an articulated manner at opposite other ends to said lower ends of said climbing rails, are structured to accept a finishing platform.
