Problems solved by technology
The disadvantage of this method is that due to the filling or pressing of the concrete slab, the prestressing force at the end of the prestressing tendon is changed under certain circumstances.
Also, taking this approach can have an adverse effect on the adjustment, so it has to be rechecked
The alignment accuracy of the concrete slabs can also be adversely affected due to temperature differences when tensioning and filling the butt joints and during filling

Embodiment Construction
[0051] FIG. 1 shows a section of a reinforced concrete prefabricated slab 10 . In this embodiment, the reinforced concrete prefabricated panel 10 has a plurality of bumps 12 . As an alternative, it can also be a continuous strip or a concrete groove, which can be continuous or intermittent. The protuberances 12 are arranged in two rows along the longitudinal direction of the reinforced concrete prefabricated slab 10, according to their purpose of use as shown in the figure, so that they can be used for fastening rails such as high-speed rails. A steel rail 30 is fixed on each row of bumps 12 . A rail 30 is secured to each protrusion 12 by a fastener 31 shown only symbolically in the drawings. The fastening element 31 can be fastened in the pin 32 or in a corresponding hole, if desired.
[0052] In the transverse direction of the prefabricated reinforced concrete slab 10 , two bumps 12 are respectively arranged on a section of the prefabricated reinforced concrete slab 10 . ...

The invention relates to a pre-assembled plate consisting of armoured concrete, especially for the use as a component of a solid roadway for high-speed means of transport. At least two steel rods extending in the longitudinal direction of the pre-assembled plate of armoured concrete (10) and protruding over the concrete surface thereof on the front face (17) are provided. The pre-assembled plate (10) is provided with at least one, preferably several, predetermined breaking point / s (15) which extend / s crosswise in relation to the steel rods (19). The steel rod (19) is anchored in the area between the front face (17) of the pre-assembled plate (10) and the first predetermined breaking point (15) respectively and is mounted in the direction towards the respective front face (17) in the longitudinal direction thereof in an essentially freely moveable manner. According to a method for producing a plate composite structure of pre-assembled plates of armoured concrete (10), the pre-assembled plate (10) is placed and exactly positioned. A casting compound (42) is underpoured under the exactly positioned pre-assembled plate. The pre-assembled plate (10) is connected to the adjacent pre-assembled plate (10) by casting the joint and connecting the steel rods (19) after the casting compound (42) has hardened.
Description
field of invention [0001] The invention relates to a reinforced concrete prefabricated panel and a manufacturing method thereof. In particular, it relates to a reinforced concrete prefabricated slab used as a fixed running track member of a high-speed vehicle, comprising at least two longitudinally extending reinforced concrete prefabricated slabs 10, and protruding from the end surface 17 of the steel bar 19 through its concrete surface, and at least one, most Preferably a plurality of marked damage points 15 of reinforced concrete prefabricated slabs 10 transversely intersecting with steel bars 19 and their manufacturing method. Background technique [0002] A similar type of reinforced concrete prefabricated slab is known from DE 197 33 909 A1. This reinforced concrete prefabricated panel is intended for the construction of a panel composite structure, in particular for the construction of fixed running tracks for high-speed rail transit. In the reinforced concrete pref...
