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

[0052] exist figure 1 A portion of a reinforced concrete prefabricated slab 10 is shown in FIG. 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.

[0053] In the transverse direction of the prefabricated reinforced concrete slab 10 , two bumps 12 are respectively arranged on a section of the prefabricated reinforced c...

Abstract

Disclosed is a method to produce a combined board structure with reinforced concrete prefabricated plates(10), which is used to fix running tracks for high-speed vehicles; the prefabricated plates(10) are laid along the ground and are positioned with precision; basal pouring composite material(42) is poured at the undersides of the precisely positioned prefabricated plates; after the basal pouring composite material(42) is hardened, one prefabricated plate will be connected with the adjacent prefabricated plates through pouring joints and connecting reinforcing steel bars.

Description

[0001] This application is a divisional application of application number 00813858.3 (international application number PCT / EP00 / 09188). technical field [0002] The invention relates to a method for manufacturing a panel composite structure, in particular to a method for manufacturing a panel composite structure with a reinforced concrete prefabricated panel. Background technique [0003] 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 prefabricated slab, there are at least two steel bars extending in the longitudinal direction of the prefabricated slab and protruding from the two end surfaces of the prefabricated slab. Each steel bar is anchored immovably in only one position in the prefabricated reinforced conc...
