Problems solved by technology
The disadvantage of using this method is that the prestressed state of the end of the prestressed steel bar will change under certain circumstances due to the occurrence of joint filling material or insufficient compaction.
In addition, using this method may affect the calibration, so that it has to be re-checked
Different temperatures also have a negative effect on the accuracy of precast concrete slabs when tensioning and filling butt joints and when gaps in the grouting compound occur

Embodiment Construction
[0030] figure 1 Shown is an isometric view of two prefabricated panels 1 and 2 in which the two parts of the tensioning device 3 are arranged. The prefabricated panels 1 and 2 are each only partially shown. In the prefabricated panels 1 and 2 designed for fastening the running track, often a plurality of tensioning devices 3 are distributed over the width of the prefabricated panels 1 and 2 , usually six in number.
[0031] The tensioning device 3 consists of a connecting sleeve 4 and a tensioning box 5 . The connecting sleeve 4 and the tension box 5 are respectively connected with an anchoring steel bar 6,7. The anchor bars 6 and 7 are anchored in the prefabricated panels 1 and 2 . In the region of its ends, at least one of the anchor bars 6 and 7 is placed in the prefabricated panel elements 1, 2 and is stretchable along its longitudinal axis. Stretching can take place, for example, by enclosing the anchoring bars 6, 7 in a tightened hose, which are protected by the anch...

A method for manufacturing a panel composite structure using reinforced concrete prefabricated panels (1, 2), especially a method for manufacturing a panel composite structure used as a fixed track for high-speed vehicles, comprising at least two prefabricated panels The anchor bars (6, 7) extending in the longitudinal direction of the pieces (1, 2) and terminating in the end face range, and the joints (8) between the adjacent prefabricated panels (1, 2), wherein the two prefabricated The plates (1, 2) are aligned and fixed to each other. The anchoring reinforcements (6, 7) of adjacent prefabricated panel elements (1, 2) arranged substantially in a straight line are connected to each other, and the joint (8) is poured with a joint compound (12). The ends of the two anchor bars (6, 7) are connected to a tensioning device (3) equipped with wedges (14, 17, 18), and the joint (8) is formed by placing the wedges (14, 17, 18 ) is inserted into the tensioning device (3) to obtain prestress. The object of the invention is also the corresponding prefabricated slabs made of reinforced concrete and the tensioning device for connecting and tensioning the anchor bars on the concrete prefabricated slabs (1, 2).
