    Summary
    Method for producing a carriageway slab (1) with precast slabs (2) below. The method is characterized in that at least two lanes (7) are formed on the upper side (18) of a longitudinal bridge beam (5), prefabricated panels (4) are attached to a carriage (10) at a mounting location (31) with tension members (11) and are then lifted, the prefabricated panels (2) are transported and lowered from the assembly site (31) to the installation location (32) and then a layer of concrete (3) is applied to the prefabricated panels (2).

    Process for the production of a pavement slab with prefabricated slabs underneath
    The invention relates to a method for producing a pavement slab with underlying prefabricated slabs and an overlying concrete layer made of in-situ concrete for a bridge, the prefabricated slabs being moved with a trolley from an assembly site to an installation location, lowered at the installation location and during the application and hardening of the concrete layer are held by tension members attached to the wagon, as well as pavement slabs produced using this method.
    WO / 2016/187634 A1 describes the production of a carriageway slab with prefabricated slabs underneath and a concrete layer made of in-situ concrete arranged above it for a bridge with a bridge longitudinal member. In this method, a trolley is manufactured that can be moved in the longitudinal direction of the bridge on support structures that are mounted on the top of the bridge side member. With the trolley, precast panels are transported from an assembly station to an installation location. At the installation site, the precast panels are lowered until the edges of the precast panels are supported on the bridge side member. After lowering, the prefabricated panels are still attached to the car using tension members. Reinforcement is then laid and a layer of concrete is applied. After the concrete layer has hardened, the fastenings of the precast panels on the tension members are released. The trolley is then moved to an assembly station in order to pick up additional precast panels if necessary.
    A disadvantage of the method described in WO / 2016/187634 A1 is the complex production and later disassembly of the support structures on the top of the bridge side members along the entire length of the bridge.
    It is therefore the object of the present invention to provide a method for producing a carriageway slab with prefabricated slabs underneath and a concrete layer arranged above it, which enables the production of a carriageway slab with a trolley without relying on the support of the trolley by support structures arranged on the top be and which offers economic and technical advantages over the known method.
    This object is achieved by the method steps specified in the characterizing part of claim 1. Advantageous developments of the invention are defined in the subclaims.

    -m- finally, the carriage is moved to an assembly station in order to accommodate further precast panels there if necessary.
    In the manufacturing process according to the invention, the process steps -a to -c- essentially relate to the formation of a lane on the top of the bridge side member, and the equipment of the car with wheels and a device for moving the car on a layer of concrete.
    The subsequent process steps -d- to -n- essentially relate to a sequence of manufacturing steps to transport sections of prefabricated panels with the help of the trolley to the intended installation location of the prefabricated panels and storing them there in such a way that a concrete layer made of in-situ concrete can be applied to the prefabricated panels , After the hardening of the concrete layer, the fastenings of the prefabricated panels are loosened at the lower end points of the tension members and the carriage is moved to the original or another assembly location in order to accommodate additional prefabricated panels if necessary. For this purpose, the carriage is essentially moved in the longitudinal direction of the bridge to an assembly site, at which prefabricated panels are attached to the lower end points of the tension members. The panels are then raised and the carriage is moved to the intended installation location of the precast panels, the prefabricated panels being lowered at the corresponding installation location. A reinforced layer of in-situ concrete is then applied to the precast slabs. After the / 24 • · ··· · ···· ·: :: 3 ···. · ..::::

    -d- to -m- the section-by-section manufacturing process is continued until the
    Roadway slab along the entire length of the bridge is completed.
    The method according to the invention has the advantage over the method described in WO / 2016/187634 A1 that no support structures have to be mounted on the top of the bridge side member and disassembled again after the roadway slab has been produced.
    In the method according to the invention, at least two lanes for the wheels of the car are formed on the top of the bridge side member. In an advantageous variant of the method according to the invention, the lanes are formed between the composite means mounted on the top of the bridge side member.
    In a further advantageous embodiment, at least one hydraulic coupling is installed in the carriage, as a result of which the wheels arranged in a lane exert approximately the same forces on the bridge side member.
    In a preferred embodiment, the reinforcement to be arranged in the concrete layer is laid on the assembly site on at least one precast slab, preferably on all precast slabs.
    In a further advantageous embodiment, a first concrete layer is applied to the assembly site on at least one precast plate, preferably all precast plates, and a second concrete layer is applied to the installation site on the first concrete layer.
    By applying a first layer of concrete or other measures, the precast panels can be connected to a continuous panel at the assembly site.
    To relieve the wheels, it can be advantageous if supports for the car are installed at the installation location before the application of the concrete layer on the top of the side member.
    In a preferred embodiment, the supports are installed on the trolley, lowered at the installation site and raised again after the concrete layer has hardened.
    To reduce the dead weight of the deck slab, it can be advantageous if displacement bodies are mounted on the precast slabs.
    Within the scope of the invention, a carriageway slab with underlying prefabricated slabs and an overlying concrete layer of in-situ concrete for a bridge with a longitudinal bridge member is provided, which can be produced by a method according to one of claims 1 to 9.

    The first embodiment of the method according to the invention is shown in FIGS. 1 to 13. According to FIG. 1, six prefabricated panels 2 are laid on four assembly supports 20 on assembly site 31. Before laying the prefabricated panels 2, the natural dimensions of the bridge side member 5 can be recorded at the installation location 32. The prefabricated panels 2 can be laid on the assembly site 31 taking these natural dimensions into account so that they can be supported on the bridge side member 5 at the installation location 32 with a precise fit. After laying the prefabricated panels 2 on the assembly supports 20, the joints 21 between the prefabricated panels 2 could be filled with grout or concrete. Recesses 16 are formed at some points at which the prefabricated panels 2 are supported on the bridge longitudinal beam 5 at the installation location 32. In the example shown in FIG. 1, twelve cutouts 16 are present. The reinforcement to be arranged in the concrete layers 3 is then laid on the precast slabs 2.
    2, a first concrete layer 3 made of in-situ concrete is applied to the prefabricated panels 2 on the assembly station 31. The joints 21 between the precast slabs 2 are filled with concrete when the first concrete layer 3 is applied. The individual prefabricated panels 2 are connected by the reinforcement and the first concrete layer 3 to form a coherent panel 26 which has twelve recesses 16.
    According to FIG. 3, in the next method step, a carriage 10 is moved to the assembly site 31 on a longitudinal bridge 5. In the first exemplary embodiment, the bridge longitudinal beam 5 consists of two steel beams 9. The steel beams 9 can be connected by cross braces or cross beams, which are not shown in this exemplary embodiment for the sake of clarity. In this example, the carriage 10 consists of a steel frame construction. Alternatively, the trolley could also consist of a truss structure. The carriage 10 has eight wheels 8. The carriage 10 is moved by the wheels 8 rolling in the two lanes 7 formed on the upper side 18 of the bridge side member 5. The two lanes 7 are each arranged between the composite means 6. The four wheels 8, which are arranged in a lane 7, can be connected to one another by a hydraulic coupling installed on the carriage 10, as a result of which the wheels 8 arranged in a lane 7 exert approximately the same forces on the bridge side member 5. A hydraulic coupling could be implemented with hydraulic presses that are installed above the wheels 8. Advantageously, the carriage 10 can only be moved to the assembly site 31 after the reinforcement has been laid and the first concrete layer 3 has been applied, since this makes it easier to move the reinforcement, supported by a crane, and to apply the first concrete layer 3 by means of a concrete pump. After / 24 • ·· ·· · ···· ·: :: s ···. · ..::::
    ···· · · ··· ·· ·· ··· ·· ··· ·· the positioning of the carriage 10 at the assembly site 31, the plate 26 is attached to the carriage 10, raised and transported to the installation location 32.
    According to FIG. 4, the carriage 10 and the plate 26 attached to the carriage 10 are at the installation location 32. FIG. 4 shows a state immediately before the plate 26 is lowered, which is still in an elevated position. The plate 26 is attached to the lower end points 13 of tension members 11. The upper end points 12 of the tension members 11 are attached to the carriage 10. The carriage 10 is positioned such that the cutouts 16 are arranged above the composite means 6 arranged on the upper side 18 of the bridge side member 5. After the exact positioning of the carriage 10 at the installation location 32, the wheels 8 can be blocked in order to prevent the carriage 10 from rolling away. The carriage 10 can also be fixed at the installation location 32 by temporarily connecting the carriage 10 to the bridge side member 5 or by other measures.
    A vertical section through the carriage 10 positioned at the installation location 32 is shown in FIG. 5. The plate 26 is fastened to the carriage 10 with tension members 11. The plate 26 is in an elevated position because a collision with the composite means 6 must be avoided during the movement of the carriage 10 from the assembly site 31 to the installation location 32. The wheels 8 of the carriage 10 are arranged in the lanes 7 formed between the composite means 6 on the upper side 18 of the bridge side member 5. The weight of the carriage 10 and the plate 26, which consists of the prefabricated plates 2 and the first concrete layer 3, is transferred from the wheels 8 to the bridge side member 5.
    A section corresponding to FIG. 5 after lowering the plate 26 is shown in FIG. 6. After lowering, the plate 26 is supported on the bridge side member 5. Depending on the geometric floor plan dimensions of the plate 26, the design of the reinforcement arranged in the first concrete layer 3 and the thickness of the plate 26, the plate 26 can be supported on the bridge side member 5 in such a way that the tension members 11 are completely relieved. However, it would also be possible to support the plate 26 on the bridge side member 5 such that only part of the weight of the plate 26 is supported on the bridge side member 5 and the remaining part of the weight of the plate 26 is taken over by the tension members 11 and introduced into the carriage 10 becomes.
    7 shows a detailed view of a wheel 8 of the carriage 10, which is arranged between the composite means 6 in a lane 7 on the upper side 18 of the bridge side member 5. Strips 22 are glued to the top 18 of the bridge side member 5. The strips 22 can for example consist of an elastomer. An anchor 14 for the lower end point 13 of a tension member 11 is installed in a prefabricated panel 2. This anchor 14 consists of a steel plate 35 and a threaded nut 36 which is welded to the top of the steel plate 35. The threaded nut 36 is partially arranged in the first concrete layer 3. On the outside of the threaded nut 36, a push tube 37 is attached. At the lower end point 13 of the tension member 11, a thread is formed, which enables the tension member 11 to be fastened in the anchor 14.
    / 24
    FIG. 8 shows a detailed view corresponding to FIG. 7 after the plate 26 has been lowered and the plate 26 has been placed on the upper side 18 of the bridge side member 5. When the weight of the plate 26 is transferred from the carriage 10 to the side member 5, the strips 22 pressed together. The compression of the strips 22 makes it possible to compensate for inaccuracies in construction between the underside 19 of the prefabricated panels 2 and the top 18 of the bridge side member 5. A second important function of the strips 22 is to provide a seal between the underside 19 of the prefabricated panels 2 and the top side 18 of the bridge side member 5. The space 24 between the underside 19 of the prefabricated panels 2 and the upper side 18 of the bridge side member 5, the height of which corresponds to the thickness of the compressed strips 22, must be filled with grout or concrete in order to protect the upper side 18 of the bridge side member 5 from corrosion to ensure.
    9, a second concrete layer 3 is applied to the lowered plate 26. The surface of the first concrete layer 3 must be made so rough that there is a good bond effect in the construction joint between the first and the second concrete layer 3. In this step, the weight of the second concrete layer 3 is guided to a small extent via the bending load-bearing action of the plate 26 to the two steel beams 9 of the bridge side member 5 and to a greater extent introduced into the carriage 10 via the tension members 11. The weight of the second concrete layer 3 taken over by the carriage 10 is introduced into the bridge side member 5 via the wheels 8.
    10, a device 15 for moving the carriage 10 is installed on the concrete layer 3 in the next step as soon as the second concrete layer 3 has reached a predetermined minimum strength. The tension members 11 are then removed in the next step of the method according to the invention. A complete dismantling of the tension members 11, which is shown in Fig. 10, is not absolutely necessary. The release of the connections between the lower end points 13 of the tension members 11 and the anchors 14 installed in the plate 26 is sufficient to introduce the entire weight of the carriageway slab 1 into the bridge side member 5 via a bending load-bearing effect of the carriageway slab 1 and to relieve the carriage 10. After the transfer of the weight of the plate 26 and the second concrete layer 3, which together form the carriageway plate 1, the weight of the carriage 10 is transferred from the wheels 8 to the device 15 for moving the carriage 10 on the second concrete layer 3. This rearrangement can be accomplished, for example, as shown in FIG. 10, by lifting and folding the wheels 8. Subsequently, the carriage 10 can be moved by means of the device 15 for moving the carriage 10 on the concrete layer 3 to the assembly site 31, in order to accommodate further precast panels 2 there if necessary.
    A bridge 4, which comprises two abutments 33, five pillars 34 and a bridge side member 5, is shown in FIGS. 11 to 13. The carriage 10 is moved by means of winches to the assembly site 31, which is arranged here over one of the two abutments 33. At assembly location 31, plate 26, which consists of precast plates 2 and the first / 24: :: 8 : ··. : ..: ':::
    ···· · · ··· ·· ·· ··· ·· ··· ··
    Concrete layer 3 is formed, attached to the carriage 10 by means of tension members 11. The plate 26 is raised in order to avoid contact with the composite means 6 mounted on the bridge side member 5 when the carriage 10 is being moved in the longitudinal direction of the bridge 4 and to enable the already completed construction sections of a roadway plate 1 to be passed over. In order to drive over already completed construction sections of the carriageway slab 1, the installation of the device 15 for moving the carriage 10 on a concrete layer 3 is necessary.
    12, the carriage 10 and the plate 26 attached to it are moved in the next process step from the assembly site 31 to the intended installation location 32. At the installation location 32, the plate 26 is lowered until the prefabricated plates 2 rest on the upper side 18 of the bridge side member 5. The second concrete layer 3 can then be applied. After the second concrete layer 3 has hardened, a device 15 for moving the carriage 10 is installed on the concrete layer 3, the tension members 11 are released from the anchors 14 in the prefabricated panels 2 and the carriage 10 is moved to the assembly site 31 so that the panel 26 there can be taken over for the next construction phase.
    The assembly site 31 is located on an abutment 33 in the first embodiment. It can also be advantageous to move the assembly site 31 to the bridge 4 after the first sections of the carriageway slab 1 have been produced. 13, the remaining sections of the carriageway slab 1 of the bridge 4 are produced using the method according to the invention. Subsequently, the bridge 4 is completed in the usual way by applying a seal to the surface of the concrete layer 3 and then applying a pavement.
    A second embodiment of the method according to the invention is shown in FIGS. 14 to 18. 14, the carriage 10 is positioned at the installation location 32. In this example, the longitudinal bridge beam 5 consists of prestressed concrete and, according to FIG. 14, has a trough-shaped cross section with a base plate 27 and two webs 28. Four prefabricated panels 2 are fastened to the lower end points 13 of the tension members 11. Two prefabricated panels 2 are arranged between the webs 28. The two other prefabricated panels 2 are arranged in the projecting areas. Displacement bodies 23 are arranged on the prefabricated panels 2 arranged between the webs 28. The displacement bodies 23 have a prismatic shape and serve the purpose of reducing the dead weight of the concrete layer 3 in the field area between the two webs 28. No prefabricated panels 2 are arranged above the webs 28 of the bridge side member 5. The composite means 6, which are not shown in FIG. 14 for the sake of clarity, can therefore be arranged anywhere on the upper side 18 of the bridge side member 5.
    During the movement of the carriage 10 with the prefabricated panels 2 from the assembly site 31 to the installation location 32, the prefabricated panels 2 are connected to the carriage 10 by / 24
    Horizontal movements of the precast slabs 2, which are caused by inertial forces
    Starting or braking of the car 10 could be prevented. Before the
    Lowering the precast panels 2, the connections of the precast panels with the
    Carriages 10, which are not shown in FIG. 14 for the sake of clarity, are solved.
    In this exemplary embodiment, additional supports 17 are installed between the upper side 18 of the bridge girder 5 and the carriage 10 before the application of the concrete layer 3 to the precast slabs 2. These supports 17 take over part of the weight of the concrete layer 3. This reduces the load on the wheels 8 when the concrete layer 3 is applied. The supports 17 must either be arranged in recesses 16 or be protected from contact with the concrete layer 3 by other measures. It is also possible to install the supports 17 on the carriage 10, to lower them at the installation location 32 before the application of the concrete layer 3 in order to bring them into contact with the upper side 18 of the bridge side member 5, and to raise them again after the concrete layer 3 has hardened.
    A vertical section through the carriage 10 positioned at the installation location 32 is shown in FIG. 15. The prefabricated panels 2 are attached to the carriage 10 with tension members 11. The prefabricated panels 2 are in an elevated position because a collision with the composite means 6 must be avoided during the movement of the carriage 10 from the assembly site 31 to the installation location 32. Displacement bodies 23 are fastened on the prefabricated panels 2 arranged in the middle. The insertion of displacement bodies 23 serves to reduce the dead weight of the finished carriageway slab 2. The wheels 8 of the carriage 10 are arranged in the lanes 7 formed between the composite means 6 on the upper side 18 of the bridge side member 5. The weight of the carriage 10 and the prefabricated panels 2 is transferred from the wheels 8 to the bridge side member 5.
    A section corresponding to FIG. 15 after the prefabricated panels 2 have been lowered is shown in FIG. 16. After lowering the prefabricated panels 2, the weight of the prefabricated panels 2 is still taken over by the tension members 11 and introduced into the carriage 10, because the prefabricated panels 2 are not supported on the bridge side member 5 in this embodiment.
    17 shows a detailed view of a wheel 8 of the carriage 10, which is arranged between the composite means 6 in the lane 7 on the upper side 18 of the bridge side member 5. The composite means 6 are formed by brackets 30 made of reinforcing steel, which are arranged in the web 28 of the bridge side member 5. 17 shows an anchor 14 arranged in a prefabricated panel 2. The lower end point 13 of a tension member 11 is fastened to the anchor 14. A push tube 37 to protect the tension member 11 from contact with the concrete layer 3 is attached to the anchor 14.
    FIG. 18 shows a detailed view corresponding to FIG. 17 after the prefabricated panels 2 have been lowered. In this exemplary embodiment, the prefabricated panels 2 are not supported on the bridge side member, but rather are located somewhat after the lowering / 24 • · · · «· ··· ·· ·· ··· ·· ··· ·· below the top 18 of the bridge side member 5. Seals 25 are arranged in the spaces 24 between the prefabricated panels 2 and the web 28. When applying the concrete layer 3 made of in-situ concrete, which takes place after the reinforcement has been laid, the seals 25 prevent the concrete from escaping.
    A third embodiment of the method according to the invention is shown in FIG. 19. 19, the carriage 10 is positioned at the installation location 32. In this example, the bridge longitudinal beam 5 consists of prestressed concrete and, according to FIG. 19, has a box-shaped cross section with a base plate 27, a cover plate 29 and two webs 28. Prefabricated panels 2 are attached to the lower end points 13 of the tension members 11. The prefabricated panels 2 are arranged in the projecting areas. This exemplary embodiment shows that the method according to the invention can also be used advantageously for producing the cantilever plates of bridges 4 which have a box-shaped bridge longitudinal member 5.
    In the examples, two lanes 7 were formed on the bridge side member 5. However, with the method according to the invention it is also possible to form more than two lanes on a longitudinal bridge member 5. This can be advantageous, for example, if the bridge longitudinal beam 5 has three steel beams 9 in the longitudinal direction of the bridge 4.
    In the examples, the lower end points 13 of the tension members 11 were provided with a thread and screwed into the threaded nuts 36, which together with welded-on steel plates 35 form an anchor 14. The formation of an anchor 14 for the lower end points 13 of the tension members 11 in the prefabricated panels 2 or in the prefabricated panels 2 and a first concrete layer 3 is possible in many other ways, for example by clamping or friction connections.
