A climbing formwork system for mass concrete construction, in particular for building a dam or for hydropower industry, the climbing formwork system comprising:
- a movable panel defining a wall of the climbing formwork system;
- said movable panel having an inner surface facing a filling volume of the climbing formwork system for containing the concrete and an outer surface facing an external environment;
- a track having a main extension along a longitudinal direction extending along a direction of climbing and positioned at least partially inside said filling volume of the climbing formwork system;
- said track comprising a sliding channel closed with respect to the filling volume and having a longitudinal slit extending along the longitudinal direction;
- said slit being configured to realize a communication between said sliding channel and said external environment or said movable panel, wherein said track is disposed in contact with said inner surface and said slit is at least partially covered by said inner surface;
- said track defining a lateral extension of said movable panel along a lateral edge of the same movable panel;
- a climbing element slidingly inserted in said sliding channel and configured to slide along said longitudinal direction;
- said climbing element comprising a connection portion projecting through said slit and configured to be connected with a portion of said movable panel;
- and
- fastening elements operatively connected between said connection portion of the climbing element and the movable panel in order to maintain the movable panel fixed to the climbing element in a union condition, wherein said fastening elements comprise a plate fixed to a portion of said outer surface through at least a bolt.
