Abstract: A method for producing a concrete tube for a hyperloop passenger transport system. The concrete tube is concreted in situ by means of a formwork device. The formwork device has a formwork carriage which moves forwards during concreting. The formwork carriage has an inner form and an outer form for shuttering the concrete tube. An interspace between the inner form and outer form is filled, in particular continuously, with concrete. The solidified concrete tube can be supported on pillars via bearings. The freshly solidified portion of the concrete tube is preferably supported on the inside by inner rollers and on the outside by outer rollers. In order to support the formwork carriage on the pillars, the formwork device can have supporting rollers. The formwork device for implementing the method and to the concrete tube produced by the method for the hyperloop passenger transport system.

Abstract: The invention relates to a self-climbing system (1) for a concrete structural body (2), having a climbing rail (10) and having a climbing unit (12) which is axially movable along the climbing rail (10), wherein a control rod (24) is designed, in predetermined positions (18a, 18b) of a linear drive (18), to apply a torque (D) to at least one of the actuating elements (20, 22). The invention also relates to a self-climbing method.

Abstract: The invention relates to a method for producing a concrete tube (12) for a hyperloop passenger transport system. The concrete tube (12) is concreted in situ by means of a formwork device (10). The formwork device (10) has a formwork carriage (34) which moves forwards during concreting. The formwork carriage (34) has an inner form (20) and an outer form (22) for shuttering the concrete tube (12). An interspace (24) between the inner form (20) and outer form (22) is filled, in particular continuously, with concrete (32). The solidified concrete tube (12) can be supported on pillars (58a, 58b) via bearings. The freshly solidified portion of the concrete tube (12) is preferably supported on the inside by inner rollers (52a, 52b) and on the outside by outer rollers (54a). In order to support the formwork carriage (34) on the pillars (58a, 58b), the formwork device (10) can have supporting rollers (56a, 56b).

Abstract: A timber support (1) for the construction industry, has a top girder (3) and a bottom girder (4) which are interconnected using a joining element (6). A protective cap (10) that surrounds the end (9) of the girder is provided for the end of the girders. The protective cap (10) for the end of the girders has at least one fastening bracket (15) which partially covers a side of the joining element (6), and the fastening bracket (15) for attaching the protective cap (10) for the end of the girders is fixed to the side of the joining element (6) with the help of fastening means.
