Abstract

Prefabricated kit for producing a station platform which is variable in its dimensions, in which platform slabs (1) are laid on foundations (4) with interposition of spacer elements (3). The spacer elements (3) can be replaced without damaging the other construction elements (1, 3, 4). The platform slabs (1) may be arranged in various horizontal positions above the foundations (4) in order to compensate for horizontal differences in size in relation to the axis of the track.

Description

The present invention relates to a prefabricated kit for creating a changeable platform with one or more platform plates.

In the conventional design, platforms are a stationary structure executed. Such platforms are manufactured on the condition that they should remain unchanged for many generations. Such static However, buildings meet the requirements of modern Schlenenverkehr no longer fair. On the one hand, they are inflexible in terms of requirements, based on new technical developments. On the other hand, they don't offer the possibility to measure inevitably in a simple and inexpensive way Distance corrections to be made later on the building. Among the It no longer meets modern comfort and security requirements tolerable to accept such deviations without correction. Last but not least From today's point of view, the conventional time-consuming and expensive construction complain about.

In the past it has been used to simplify the construction of platforms Approaches with prefabricated kits for platforms are given. So describes the EP-357 161, for example, a platform consisting essentially of three Basic elements is built. Initially, these are U-shaped Concrete base, which is set at fixed intervals parallel to the track become.

Then on the vertical legs of the U-shaped concrete base Base to base two longitudinal beams laid parallel to the rail run. Finally, the longitudinal beams are rectangular upwards Platform slabs covered and all connections and joints closed and glued. Such a platform system reduces the Construction time of a platform compared to the fixed construction, however, is the Handling the massive longitudinal beams and the several platform slabs still relatively expensive. Furthermore, the platform slabs not against sagging or "sagging" to the unsupported center protected between the two longitudinal beams. Another particular disadvantage is to mention that the platform through the permanent connection of the Components are not suitable for later easy conversion, and in particular, no dimensional adjustment of the system allowed.

A platform kit is also described in DE-43 16 203, which Contains in-situ concrete foundations, crossbeams and platform slabs. In doing so the crossbars attached to the in-situ concrete foundations and then by Crossbar placed on crossbar platform slabs, which at their Bottom box-shaped support beams included. This Platform slabs are firmly connected to the crossbeams. This system has similar drawbacks to that previously described.

In particular, no dimensional adjustment and height adjustability is provided, and the fixed connection of the components leads to a building, which is not easily changed afterwards.

A platform is described in the published patent application DE 42 05 192 A1, in which so-called spacer elements are arranged so as to be fixed against displacement on in-situ concrete foundations that are spaced along the rail. Longitudinal beams are then laid from spacer element to spacer element parallel to the rails and parallel to one another, which finally carry an in-situ concrete slab as platform platform. All components are secured by lateral bolts or similar measures. As an advantage, the published patent application emphasizes that the height of the platform can be easily changed during later conversions by lifting the in-situ concrete slab and replacing the spacer elements with others. The platform platform is manufactured at the construction site in order to be able to execute it continuously and to achieve a better adaptation to curve areas.
However, this on-site manufacturing also has several disadvantages. On the one hand, a lost formwork that is only fastened in grooves is used. Therefore, for purely static reasons, the width of the platform is limited due to the high loads that the in-situ concrete ceiling places on the lost formwork. are to be counted.
In addition, in-situ concrete has to set up to 28 days, which extends the construction time required. Weather conditions and frost can also hinder the construction site.

Furthermore, it is the one shown in the published patent application Platform around a complete platform as a rigid plate. This plate can only be expanded by cutting the concrete. By destruction The reusability of the reinforcement is therefore very limited.

A height-adjustable platform (for trams) also describes the article "Retractable traffic islands" (traffic technology, issue 24 v. 12/20/1935, page 666). The platform slab rests in the normal state four wooden blocks. By removing the wooden blocks, they can be sunk into the ground, i.e. be adjusted at street level. The platform slab is included vertically movable within a given shaft.

The disclosed in the aforementioned publication and in DE 42 05 192 A1 The height of the traffic island or platform system can be adjusted in the In practice, however, lead to problems because between the usual platform heights (e.g. 38 cm above the top edge of the rail (SOK)) and larger platform heights (e.g. 55 cm, 76 cm and 96 cm above sea level SOK) the desired distance from the platform edge can change from the track axis. Therefore, in these cases the Height adjustment to an undesirable and intolerably large distance from the Guide the platform from the track axis or from the carriage entry.

DE 148 132 finally describes a height-adjustable platform, however, the horizontal adjustability is not mentioned.

In contrast, the present invention has the task of one Prefabricated kit for the creation of changeable platforms available to provide, which can be set up and dismantled in a time and cost-effective manner the platform and the replacement of components, and the subsequent changes in the dimensions of the platform, especially the Platform height allowed. The platform should be mobile in the sense that Reconstruction should also be possible at another location. At a Height changes should avoid disadvantages that have changed from Distances to the track axis can result.

The platform should also be suitable as part of renovation measures to be installed over the remains of the old platform with partial or complete use of the old platform edge with its associated strip foundations. In addition, it should also be able to be built in difficult locations, for example on dams.
After all, the platform should also be able to serve as a provisional or makeshift platform in those cases where a platform is only built for a certain period, e.g. in the form of a platform extension, because longer trains should stop at a platform for a certain time or in the event that that a platform is to be erected temporarily at a different location and only comes into its final position later.

• dass der Bahnsteig komplett modular aufgebaut ist und aus austauschbaren Einzelkomponenten ohne dauerhafte Verbindung zwischen den Bauelementen besteht, so dass er von 38 bis 96 cm über der Schienenoberkante höhenvariabel und seitenvariabel ist, und dessen Auf- und Abbau sowie eine Auswechselung von Bauteilen ermöglicht wird,
• dass die Bahnsteigplatten an ihrer Unterseite Stützbereiche haben, innerhalb derer sie an beliebiger Stelle auf die Stützpunkte des Bahnsteigunterbaus aufgesetzt werden können, und/oder wobei der Bahnsteigunterbau an seiner Oberseite Stützbereiche hat, innerhalb derer die Bahnsteigplatten an beliebiger Stelle aufgesetzt werden können, so dass der Spielraum für eine Horizontalverschiebung der Bahnsteigplatten bis zu 5 bis 20 % der Bahnsteigbreite beträgt.

This object is achieved by a prefabricated kit for creating a changeable platform containing one or more platform slabs and a platform substructure with foundations, which is characterized in that

• that the platform is completely modular and consists of interchangeable individual components without permanent connection between the components, so that it is height and side variable from 38 to 96 cm above the top edge of the rail, and its assembly and disassembly as well as the replacement of components is made possible,
• that the platform slabs have support areas on their underside, within which they can be placed anywhere on the support points of the platform substructure, and / or wherein the platform substructure has support areas on its top side, within which the platform slabs can be placed anywhere, so that the The scope for horizontal displacement of the platform slabs is up to 5 to 20% of the platform width.

The scope for horizontal displacement of the platform slabs is up to 5 to 20% of the platform width (typically about 1 m). The horizontal change in the position of the platform slabs is made possible by a corresponding structural adaptation and design of the platform slabs and / or the platform substructure, so that a stable platform construction is obtained within the storage space. With this design, a platform is obtained which avoids the disadvantages of the prior art that, after a change in height, the horizontal distances from the track axis are unfavorable or intolerable from the point of view of comfort and safety. A decisive improvement has thus been achieved with regard to the usability of variable-height platforms.
The horizontal changeability can be achieved so that the platform slabs at their. Have support areas within which the support points of the platform substructure can be positioned at any point. The "support points of the platform substructure" are not only to be understood as punctiform, but can in turn be extensive areas that may only come partially into contact with the platform slabs.

Conversely, the platform substructure can also have support areas on its top within which the platform slabs (via support points or Support areas) can be placed anywhere.

It is particularly advantageous that in the platform system according to the invention the foundations can lie outside the pressure range of the track. Typically there is an escape area under the platform slab approx. 70 cm provided with a corresponding overhang of the Platform slab.

The platform slabs (and other elements of the platform) are prefabricated components, so that a factory-made kit is obtained.

In a special embodiment, the platform according to the invention can be a or contain several prefabricated spacer elements, which are soft when assembled State between the platform slab and foundations are arranged and without damaging the other elements, i.e. especially the foundations and the platform slab are interchangeable. The platform slab lie detachably connected or unconnected on the spacer elements. Likewise, the spacer elements can in turn be releasably connected or lie unconnected on the foundations. Furthermore, the platform characterized in that the horizontal position of the Platform plate on the spacers and / or the horizontal position of the Spacer elements on the foundations can be changed. The lateral position of the The platform of the platform is therefore variable during construction or reconstruction.

The platform according to the invention surprisingly comes without permanent Connections between the components. The construction alone and arrangement of the components is achieved that the platform with respect to the stress to which it is exposed is sufficiently stable. simultaneously however, the platform remains just as easy to take apart for all time, how it can be assembled. This makes it particularly possible in the course a remodeling with the built-in spacer elements against such other dimensions to replace or the spacer elements up or dismantle. This makes it possible to change the platform edge into a new one bring the desired height and position opposite the top edge of the rail. It is also possible to make dimensional adjustments by making minor corrections compensate. Such conversion and adaptation measures on Platform according to the invention are without much effort and with only a small amount To interrupt operations. In particular, is also from Advantage that the platform slab between the in-situ concrete foundations or Crossbar rests cantilevered, so that it is held in this area can be raised. The latter would be with a system according to the EP-357 161 e.g. not possible because the longitudinal beams together with the Platform slabs would be detected.

The height-adjustable platforms known from the prior art (DE 42 05 192 A1 and Verkehrstechnik 24, 666) have no lateral displaceability compared to the platform according to the invention, since the traffic island is guided vertically through the excavation and the platform system by securing elements. In contrast, the platform according to the invention can also be used to react to dimensional changes that occur, for example, when changing from different conventional platform heights (eg 38 cm above SOK) to higher ones (eg 55-96 cm above SOK). Especially under today's requirements for comfort and safety, such deviations can no longer be accepted without correction.
Furthermore, the production of the platform slab according to the invention from various prefabricated prefabricated parts, instead of from in-situ concrete, has various advantages over DE 42 05 192 A1. With the prefabricated construction of the platform slab, the width of a platform slab is only specified by the maximum possible transport dimensions or weights. In contrast, in DE 42 05 192 A1 the width of the platform is limited by the lost formwork.
In addition, a platform plate prefabricated in the factory can be used immediately after assembly. This shortens the disability times on site considerably, since in-situ concrete is known to have to set up to 28 days. Finished parts can also be assembled in extreme temperatures (frost). This is not the case with local concreting. This also gives greater flexibility in terms of construction time.
Another major advantage of a prefabricated platform slab compared to a concrete slab on site is the division into individual slab parts separated by joints. The platform system is therefore mobile and reusable, not just liftable. A prefabricated platform can be completely dismantled in a short time. Only the permanently elastic joints have to be cut and the individual parts removed. The platform shown in DE 42 05 192 A1, on the other hand, is a complete platform as a rigid plate in which the concrete has to be cut to convert it. Due to the destruction of the reinforcement, the reusability is very limited.
The formwork required for a platform section, which is located in the transition arch in the case of curved layers, is relatively low in the precast plant according to the invention. The arch formwork only has to be adapted for each section of the platform. The sliding formwork shown in DE 42 05 192 A1, however, cannot be used in the transition arch. A prefabricated part therefore has less formwork and therefore lower costs.
Furthermore, the platform system according to the invention is completely modular and consists of interchangeable individual components. It is very easy to maintain because all individual parts can be replaced without any problems. There is no need to demolish or cut concrete. In reality, adjustments to platform platforms are often necessary, for example the later integration of overhead line masts, signals or shafts. At this point, the plate can either be completely replaced or only partially changed. Such an exchange is only possible in the substructure. The prefabricated platform slab can already have a surface designed in the factory according to the wishes of the user. This surface is the accessible surface of the platform in later use. There is therefore no need for an additional work step, for example to tile the platform or provide it with a walk-on surface. Different colored patterns are also possible here. In contrast, in DE 42 05 192 A1 an additional covering must be applied to the in-situ concrete. The factory production also guarantees high dimensional accuracy and flexibility in the surface properties, for example the use of different colored concrete and different surface roughness in one slab. In the case of in-situ concrete, this would mean an additional work step or, due to the poorer quality of the connection between the top covering and the platform slab, higher maintenance costs. Another advantage of the later surface on the underside of the formwork is the greater concrete density and surface homogeneity that can be achieved (plane level of the vibrating table). The system design according to the invention also enables a very high dimensional accuracy, since only a single adjustment of the platform plate is necessary.
With the prefabricated platform slab according to the invention, hindering systems in the platform area, such as existing masts, can be integrated into the system, i.e. cutouts and plate sizes can be selected in order to leave the location of the hindering systems when the slabs are moved the hindering system can be closed again. Existing deep drainage systems between the track and the platform can also remain or recesses are provided for this.

Due to the weight of the components, in particular the platform mat a basic stability of the arrangement is already guaranteed. An exception conceivable stress on the platform exists e.g. in that through that Bumping a rail vehicle into a horizontal shift Components could be caused. Provided such a shift not already due to the frictional forces between the components and their Own weight is adequately absorbed, can be preferred Embodiment of the invention can also be provided that the components through a special, interlocking shape against such Horizontal loads are anchored. Here are numerous different connection options conceivable, e.g. after the groove and spring principle can work. Stabilization against one Parallel displacement of the parts against each other by a corresponding one complementary, interlocking shapes can be used for both Platform plate and the spacer elements on the one hand as well as for the Spacers and the foundations on the other hand. Especially it is preferred if platform slab, spacer elements and foundations are each interlocked by appropriate shaping. The Locking against an unintentional lateral shift, however done that they have a desired lateral variability when converting the Platform not prevented. Toothings should therefore e.g. grid-like allow different engagement positions, screw connections could over Elongated holes ensure adequate flexibility.

For the spacer elements according to the invention, a division into Individual elements possible; preferably they consist of two individually bearing parts. However, it is also possible that the in-situ concrete foundations are not are in one piece and e.g. are constructed in pillar construction or for temporary restorations consist of easily reusable sleepers. In this case the one-piece or multi-piece spacer elements would also be used as bolts on drilling or Driving piles trained. This variant is possible for difficult ones Soil conditions or in difficult situations, e.g. on dams. Usually but is that from the weight of the system platform and its Equipment pressure resulting surface pressure so low that the above Foundation is sufficient.

If the spacers assigned to a foundation are not consist of one, but two or more individual blocks, in particular, it is easily possible to incline the platform in To influence the transverse direction (i.e. transverse to the direction of the rails). On the one hand can with horizontal in-situ concrete foundation by different thickness Spacers deviating from the horizontal transverse inclinations of the Platform slabs are caused. However, it is also possible to not horizontally formed in-situ concrete foundations with the help of different thick spacers or by pouring non-shrinking grout bring about a compensation so that the platform slabs horizontally or with a desired cross slope as a roof or negative roof profile. Finally, it should be noted that multi-piece spacer elements are less Have individual weight and are therefore easier to work with.

System I ist anwendbar für schmale Bahnsteige bzw. einen Außenbahnsteig.

System II ist anwendbar für Bahnsteige mit Breiten größer als 7 m, z.B. Mittelbahnsteige.

System III ist anwendbar für Bahnsteige mit Breiten kleiner als 7 m, z.B. die Randbereiche von Mittelbahnsteigen.

System IV ist eine Ausführung bei Überbauung eines bestehenden Bahnsteigs. Typische Ausgestaltungen dieser Systeme werden im folgenden näher beschrieben.

The platform according to the invention can be designed in the form of four different systems.

System I can be used for narrow platforms or an outer platform.

System II can be used for platforms with widths greater than 7 m, e.g. central platforms.

System III can be used for platforms with widths of less than 7 m, e.g. the edge areas of central platforms.

System IV is a version for the superstructure of an existing platform. Typical configurations of these systems are described in more detail below.

System I:

The platform slabs according to the invention preferably have their Underside formed in the longitudinal direction parallel support beams. This Beams give the platform slabs the necessary stability Longitudinal direction. This makes it possible to in itself the platform slab less thickness, which leads to a weight saving. As well can according to a further preferred embodiment of the invention below the platform slab also extending transversely to the longitudinal extent Carrier beams can be arranged. Such support beams, which are preferably at the beginning and at the end of the platform slab prevent this Bending the platform slab in the transverse direction. The distance of this Girder beams enable without the supporting structure of the platform system change, as a technical innovation an arrangement of the platform in the the curve radius provided for the respective track. Also as an innovation can the longitudinal edges of the platform in the specified arc radius or be designed according to other formal specifications.

The platform slabs according to the invention are preferably manufactured in this way at the factory made that recesses for the implementation of Cable protection tubes are integrated. This makes it possible without any problems necessary (especially earthing and electrical) installations to be provided for the platform. Furthermore, the invention Platform plates already have mounting sleeves for platform superstructures, e.g. Weather protection devices or information boards included. such Pre-installations complete the possibilities for quick and easy Installation of a platform with the modules according to the invention.

System II:

The kit according to the invention consists of a uniaxially tensioned Precast reinforced concrete slab in a standard width of e.g. 2-4 m. The length is that half the width of the platform, with exceptions as described below. The thickness of the The plate only has to be 14-20 cm. The plate itself has a slope for that Drainage of the surface water into a continuous channel in Center of the platform or a slope to the track. The system also exists from two edge girders (girder beams). These are unsupported prefabricated beams in a standard length up to 9 m. These edge beams take the vertical loads off the platform slab. You can use a sound absorbing surface be provided towards the track (e.g. pebbled concrete). The system also consists of a trough element. This is also a cantilever Precast girder with a standard length of 9 m, which removes the vertical loads from the Platform plate picks up and is supported on the foundation beam. Here there is the possibility of the cable routing inside the trough on the Foundation beams or the spacer. The outside of the trough can be covered with a sound absorbing layer or a curtain sound absorbing Plate. This is just here in the local transportation area Residential areas required.

The system also consists of a base beam as a precast foundation beam, which is attached to the respective edge of the platform slab, e.g. every 9 m, which braces the edge girders, connects the individual foundations and forwards the horizontal loads and distributes them into the foundations. The foundations are made of prefabricated parts or in-situ concrete and are attached to each end of a platform slab. The spacer elements are designed as prefabricated parts and ensure that the platform can be adjusted in height.
The overhang of the platform slab over the edge beam is variable, but preferably 70 cm (so-called escape area) can also be zero.

System III:

This system can be used for platform widths of less than 7 m come. It consists of a uniaxially tensioned prefabricated plate, which Regular width is 2-4 m, the length corresponds to the platform width, the thickness can run like System II, the slope also. Other components are edge beams as cantilever beams, base beams as Precast beams, in-situ concrete or precast foundations and spacers as described in System II.

System IV:

When an existing platform is built over, a precast slab is used biaxially tensioned and point-supported over an edge beam and one Middle bar attached; for outer platforms over two edge beams. Height adjustment and drainage are carried out as in the aforementioned Systems. Because the precast foundation and edge beams are about 70 cm or larger stand to the edge of the platform, do not touch the foundation of the old one Platform edge, or the old platform edge itself. This 70cm can be used as Serve escape area, in addition, such a or greater distance has the advantage that the foundation work is carried out without endangering the company (outside of the pressure area from the track). The foundations are single foundations. Also Funding must be funded, provided that it is a Central platform is made up of two platform slabs. Here, too Edge bars as for the above Systems with a sound absorbing surface can be manufactured or hung outwards.

In connection with System IV in particular, another technology can be used Height adjustability can be used where the platform slab over height-adjustable feet are supported on the platform base. This height-adjustable feet can e.g. consist of a threaded anchor, the at different depths in the platform slab or the platform substructure can be screwed in. A counter bearing for the threaded anchor can be a footplate can be formed in the other component.

There are various solutions for draining rainwater.
For example, a drainage channel can be arranged either along the longitudinal edge of the platform slab, preferably on the outer platform. In the case of medium-sized platforms and large platform widths, surface water can also be drained to both sides by means of a corresponding inclination to two sides.
Another variant is central drainage. Here, a drainage channel can be installed in the joint between two platform slabs with a half-channel / box channel under the joint. Depending on the longitudinal gradient of the slab, this drain water is led out every 9 m and drained into the existing drainage. This can be done through a recess in the central trough (System II). Systems III and IV also create the possibility of central drainage. Thanks to a backsplash on the side facing away from the track, even heavy rainwater runoff can be concentrated in just a few processes.
The advantage of the system according to the invention is that several variants of rainwater drainage are possible and it can therefore be adapted to the wishes of the user.

The surface of the platform slab is preferably equipped with a non-slip surface and integrable safety and control systems.
It can be made in different colors and structures. In particular, it is possible to use different concrete compositions for the production of the surface. Two or more different concretes can be used, e.g. those of different colors or different compositions (e.g. glass fiber concrete and concrete with other additives). These can be placed one after the other and / or next to each other in the formwork. It is also conceivable that they are arranged in a grid structure in which they are only separated by grid joints. By using different concretes, an appealing aesthetic (including color) design of the platform slabs can be achieved as well as advantageous static and functional properties.

For easy assembly, especially with the help of rail cranes or To enable excavators on site are certain dimensions and Weights of the components preferred. So should the weight of the platform slab less than 10,000 kg, preferably less than 8,000 kg. The Platform slab preferably has a width of 2 to 5 m, very particularly preferably 2.50 to 3.0 m, and a length of 4 to 10 m, preferably 5 to 7.50 m.

As an assembly aid for optional attachment of supply lines etc. on the underside of the panel, along the cross members and side members and on these even fasteners such as point anchors, anchor channels or threaded sleeves etc. are incorporated.

Of course, the prefabricated kit according to the invention is also included great advantage if no later conversion measures to Adjustment of dimensions is planned, but rather a permanent platform should be created. The time and inexpensive prefabricated construction of the The platform according to the invention definitely benefits the user, even if there are no later modifications to the platform be made.

In particular, however, it is part of the scope of the invention, the prefabricated kit to be used to create a platform with variable height and sides. A Height adjustment of the platform by larger distances from 38 cm to 96 cm above the top edge of the rail is e.g. required when others Rail vehicles are used. Such changes in the Height requirements come up at the current time Modemization of traffic systems is particularly common. So be numerous transport companies converted to other wagon technology, which is a Retrofitting the platforms required. With the use of the Height and side variable platforms according to the invention in this regard, all options for unpredictable, future Developments kept open. That is an invaluable advantage Platform according to the invention in particular when the modemization of a platform is currently due, and the need for retrofitting is already certain or likely at a later date.

In the event that the platform was installed as a temporary platform or provisional, and also in the event that a partial replacement of platform slabs is required at a later date, only the permanently elastic joints need to be cut and the slab can be dismantled as a whole, without the influence the static functions of the neighboring panels.
The lifted plates can then be reused. For this, only the permanently elastic joints are renewed. There is no disposal effort.

a) die Bahnsteigplatte zunächst angehoben wird, was vorzugsweise mit hydraulischer Pressen, Schienenkränen oder Baggern erfolgt,

b) ggf. die Distanzelemente gegen neue Distanzelemente der gewünschten Höhe ausgetauscht werden bzw. Distanzelemente auf- oder abgebaut werden oder schwundfreier Vergußmörtel unter die Distanzelemente/Bahnsteigplatte gebracht wird,c) die Bahnsteigplatte mit der gewünschten horizontalen Lage auf die Distanzelemente aufgesetzt wird.
Dieses Verfahren läßt sich mit äußerst geringem Aufwand und ohne große und langandauernde Unterbrechungen des Schienenbetriebes durchführen. Insbesondere ist es auch möglich, kleinere Korrekturen im Zentimeterbereich durchzuführen. Anstelle des Austauschens der gesamten Distanzelemente kann dabei auch eine Erneuerung bzw. Aufstockung von Lagerelementen zwischen den Bauteilen des Fertigbausatzes erfolgen. Denn nach dem Stand der Technik ist es üblich, zwischen derartigen Bauelementen sogenannte Elastomerlager anzubringen, z.B. in der Form von Neoprenstreifen. Diese Lagerelemente werden zwischen Bahnsteigplatte und Distanzelement einerseits bzw. Distanzelement und Fundament andererseits angeordnet. Die verzahnte Profilierung der Bauteile verhindert sicher eine Horizontalverschiebung der Elastomerlager. Auch können Maßtoleranzen in der Bahnsteigplatte bzw. im Ortbetonfundament oder Fundamentfertigteil problemlos durch das Einbringen von schwundfreiem Vergußmörtel unter die Distanzelemente bzw. die Bahnsteigplatte ausgeglichen werden.

A height and / or side adjustment of a platform from a prefabricated kit according to the invention is carried out by

a) the platform slab is first raised, which is preferably done with hydraulic presses, rail cranes or excavators,

b) if necessary, the spacer elements are exchanged for new spacer elements of the desired height or spacer elements are assembled or disassembled or shrink-free grout is placed under the spacer elements / platform slab, c) the platform slab is placed on the spacer elements with the desired horizontal position.
This method can be carried out with very little effort and without large and long-term interruptions in rail operations. In particular, it is also possible to make minor corrections in the centimeter range. Instead of replacing the entire spacer elements, bearing elements between the components of the prefabricated kit can also be replaced or added to. Because according to the prior art, it is common to mount so-called elastomer bearings between such components, for example in the form of neoprene strips. These bearing elements are arranged between the platform plate and the spacer element on the one hand and the spacer element and foundation on the other hand. The toothed profiling of the components reliably prevents horizontal displacement of the elastomer bearings. Dimensional tolerances in the platform slab or in the in-situ concrete foundation or prefabricated foundation part can also be easily compensated for by inserting non-shrinking grout under the spacer elements or the platform slab.

Last but not least, it is also possible within the scope of the described method replace any defective components with new ones without that a complete renewal of the platform would be necessary.

The distance of this The foundations correspond to the length of the platform slabs 1. On the foundations 4 are in one piece the spacer elements 3. These are each on the two end points of the foundations 4 are arranged. Form the spacer elements 3 on the one hand a defined support surface towards the platform slab 1; others are suitable as light and easily interchangeable elements, to perform the height and side adjustability function of the platform. By the exchange of the spacer elements 3 will be without changing the Platform slabs 1 or the in-situ concrete foundations are possible, as is the platform to subsequently change its height or position. In conclusion, the Platform slabs 1 laid from foundation to foundation, being due bridge the gap in a stable manner with their own load-bearing capacity.

Figure 2 shows the construction according to the invention schematically in the Side view. In particular, longitudinal beams 2 can also be seen, which are formed on the underside of the platform slabs 1 and there for one Ensure longitudinal stability. Likewise arranged in the transverse direction Beams (see number 2 in Figures 1 and 3) for the stability of the platform slabs in the transverse direction. In Figure 2, the overhang that the Has platform plate 1 over the beam 2. In particular through the Overhang on the narrow side is possible without changing the frame the beam changes the shape of the platform slab in this way (deviating of rectangular shape) that the composite platform slabs themselves adjust the given radii of curvature. Preferably, the Platform slabs for this purpose are trapezoidal. Furthermore form the Protrusions at the joints below the platform slabs 1 openings 11 for Cross Roads. In Figure 2 some structures are shown as an example, e.g. a lamp mast 12 that can be placed anywhere, railings, seating, Waste containers etc.

FIG. 3 shows two variants of the platform according to the invention in a front view.
FIG. 3a relates to the version with one-piece in-situ concrete foundations 4. Here too, the structure made up of cleanliness layer 5, foundation 4, spacer elements 3 and platform slab 1 with (transversely running) support beams 2 can be seen. In addition, empty pipes 6 can be seen, which run centrally below the platform plate 1 and can serve, for example, as cable protection pipes. On the front side of the platform slab, the empty tubes 6 penetrate the cross beam 2.

Figure 3b shows a similar basic structure, but here is the platform built on a pile foundation with the piles 4 '. This construction is in prefer difficult terrain and ground conditions, e.g. if the Platform being built on a dam. They are on the piles 4 ' Spacer elements 3, which can be designed as pile head beams. Furthermore are in Figure 3b arranged laterally on the platform edge Drainage channels 7, a cable trough 8, empty pipes 6, one in slots assembled railing 9 and a service hatch 10 recognizable.

FIG. 4 shows the front view of an alternative platform. First it can be seen that there are actually two platforms parallel to each other run and together form a platform of double width. Both Platforms are each based on the known structure Cleanliness layer 5, foundation 4, spacers 3 and platform slabs 1. Superstructures are indicated on the platforms, e.g. Weather protection devices and lighting measures. these can preferably in pre-assembled mounting sleeves with platform plates 1 get connected.

The essentials of the construction according to FIG. 4 are the two-part ones Spacers 3a, 3b. These provide two support points, in which the longitudinal beam 2a, 2b are placed. With the two-piece Distribution of the spacer elements 3, it is possible to control the To influence platform slab 1. For this purpose, unevenly high Spacers 3a, 3b can be selected. It is either possible to use one to compensate for the horizontal inclination of the foundation 4 or to generate a corresponding inclination of the platform slab 1.

It can also be seen in FIG. 4 that platform plate 1 and spacer elements 3a, 3b on the one hand and spacer elements 3a, 3b and foundation 4 on the other a complementary shape interlock. So they have Spacers 3a, 3b on their upper side depressions into which the Side member beams 2a, 2b are used. The spacer elements also apply 3a, 3b in turn with projections in corresponding recesses in the Foundations 4 a. This way, without further, permanent Connection measures between the components ensures that the corresponding arrangement is stable against loading with transverse forces.

FIG. 5 shows a platform slab 1 in perspective, in which a "negative Roof profile "creates a depression in the surface, at the lowest point of which Waste water drain 13 is arranged. Of course there are others too Formation of the surface according to the needs and desired waste water collection point realizable.

Figure 6 shows a section of the plate side facing away from the track. You can see a c-profile 14, which serves to reinforce the edges, and this on site I-profile 15 to be attached (wide flange bracket of the HEA or HEB version). The non-positive connection with the plate 1 is with threaded sleeves 16 Shaft anchor, e.g. type PFEIFFER, a threaded rod and a nut 25, which is easily accessible from the outside. Through openings in the top Flange either pre-defined in grid dimensions or on-site manufactured according to the requirements, e.g. Railing supports 17 torque stable and easy to install. Your attachment takes place in the lower area e.g. in a base plate 21 with screw thread. The Assembly time can also be shortened if the equipment elements are already connected to the support 19 (screwed or welded), before they are screwed together with the system plate 1.

The mounting bracket 19 can through a corresponding recess in the plate 1 flush to the concrete surface and with a permanently elastic Fugue 18 can be connected. For better drainage of water at the The wearer can do the "drainage with negative roof profile" design variant but also be installed so that the top of the flange over the Concrete surface stands.

As further variations, the fastening rail described can also other materials (stainless steel, aluminum, plastics) or other profiles (composite c-profiles instead of (I-beams, special shapes) are provided. Instead of the quiver support of the railing supports described, a Attachment to the upper or lower flange only.

When connecting the mounting bracket 19 to the system plate 1 can first make an adjustment using the one located on the lower flange side Screws 20 are made before the final screwing in the threaded sleeves 16 cast in concrete.

Figure 7 shows c-profile and I-profile in a schematic plan view and one Side view (side away from the track).

Figure 8 shows the adaptation of the track-side plate edges 26 to predetermined ones Radii. Since all plate edges are drawn over the supporting structure 27 (Cantilever panels), the edges can be changed without the load-bearing capacity of the Endanger plate. The track-side edge 26 can be convex, concave or oblique be carried out.

Figure 9 shows the possibility of also on the side facing away from the track Change the edge course without endangering the load-bearing capacity. So can you e.g. natural barriers 30 (such as a ledge, a Tree) "dodge" or set design accents.

Figure 10 shows the connection of a mounting plate 32 to the system plate 1, e.g. to attach a weather shelter to it. The transition of both plates will manufactured by the mounting bracket 19. The mounting plate 32 can also retrofitted to the system panels equipped with a mounting bracket be connected.

Figure 11 shows the systems II and III in plan as a schematic diagram. Is shown the part of a central platform that tapers towards the end. System II consists of two or more adjacent to each other in the platform width Plates 1. The plan shows the continuous trough element 40 in the Middle, the two edge elements 41 running through the length and the in Grid of e.g. 9 m across the entire width of the platform Base beam 42. System III starts where the width of the platform is one single plate allows. The criteria here are the weight and the transport size the plate. It is shown e.g. a 7 m wide and 3 m long plate tapered on one side. The system III plates are on the outside of the two lying edge bar 41 on and partially, in the example every 9 m, on the Base bar 42.

Figure 12 shows the cross section of the platform system II. In the figure is recognizable that on both sides of the trough element 40 is a cavity, in the supply lines 42 or other channels can be accommodated can. A possible attachment or foundation of is also indicated Platform structures, e.g. Platform roofs etc. The raising or lowering of the platform takes place via a spacer element 3 under the edge support 41. This spacer element is not continuous in length, but in each case placed on the base bar 42. Between edge supports 41 and Spacer 3 is a neoprene bearing 44. The drainage takes place in the figure via a half-groove 45 in the middle between the two Platform slabs. The water can flow through a recess in the trough element 40 be dissipated. A subsequent lateral shift of the Platform plate 1 is possible by spacing the two plates in the middle is enlarged (you can attach a larger half-channel 45). In this case both platform slabs can be pushed towards the track. A side Moving to one side is done by moving the complete Systems above the in-situ concrete foundation 4. The edge girder 41 can after be provided on the outside with a sound-absorbing surface.

Figure 13 shows the longitudinal section of the same platform, namely System II. Occasionally required access to the interior of the trough channel 40, e.g. to change the drainage line is possible via a side Entry 46. Access to the cavity between the trough channel and the edge beam can be created via a manhole cover in the platform slab, which is in the color of the surface can be adjusted.

Figure 14 shows the cross section of the platform system III. The structure is similar like System I, but without a central trough and with only one plate 1 over the total platform width.

Figure 15 shows the cross section of the system IV. In the figure it can be seen that an old existing platform 47 does not have to be completely removed. The two platform slabs 1 (with a smaller width, e.g. <7 m, there is also one Platform slab conceivable) are supported in the middle on a foundation finished part above. With this system, an increase is possible the details of which are shown in FIG. 17. The edge bars 41 can with a sound-absorbing surface clad or made of a large-pored concrete be made on the surface. This figure also shows that the foundation is so far from the threshold that it is not from the bottom 45 ° load spreading 48 is touched below the threshold, i.e. the track will not operate while the foundations are being laid endangered. The foundations are composed of a frost-free lean concrete layer 49, on which two precast foundations 50 are put on.

Figure 16 shows how the foundations of System IV are arranged and how Drainage of the platform can be provided. In the less broad Parts of the platform in which only one plate 1 over the entire width is provided, each plate has an inclination to a point. This Inclinations can already be provided in the panel in the precast plant. In the two- or multi-plate area, the drainage takes place in the middle between the two plates.

Figure 17 shows the detail height adjustability in System IV Platform plate 1 can be changed in height by in the shown Steel tube 51 (e.g. diameter / thickness = 35 / 2.5 mm or 38/4 mm) an anchor 52 (e.g. M20-M27) of the appropriate length and thus the plate 1 is screwed upwards. The armature 52 is supported on a downward footplate 55 (e.g. 120 × 120 × 12 mm) anchored in the concrete foundation. In the Plate 1 is a base plate 56 (e.g. 120 × 120 × 12 mm), which with the standpipe 51 and a nut 57 (e.g. M20-M27) is welded. To do that Standpipe 51 is in the plate 1, a spiral reinforcement 58. Zur The surface of the platform is the standpipe 51 through a top ground, lockable attachment ring 59 taken. The adjustment of the height is done by rotating the armature 52, which e.g. by an electric screwdriver 60 can be done with roller bearing management.

The resulting space can be created via the joint between the two panels be filled with concrete. The adjustment is guaranteed via the illustrated metal slide box 53, the seal a neoprene lip seal 54. However, this system can be used when filling with concrete cannot be lowered afterwards.

1. Als längerfristiger Baubehelf für ganze Bauphasen (einige Wochen oder Monate). Die Lage des Bahnsteigprovisoriums kann dabei gleich oder nicht gleich der Endlage des Bahnsteigs sein.

2. Als Vorabmaßnahme, d.h. im Bauzustand wird der Bahnsteig vorab an provisorischer Stelle eingebaut Später wird dasselbe System in Endzustandslage eingebaut und verbleibt dort.

3. Als zeitlich begrenzte Bahnsteigverlängerung. Dies ist z.B. erforderlich, wenn beim Bahnhofsbereitsteller für eine befristete Zeit ein längeres Gleis bestellt wird.

Figure 18 shows a makeshift platform which can be used, for example, in the following cases:

1. As a long-term construction aid for entire construction phases (a few weeks or months). The position of the provisional platform may or may not be the same as the final position of the platform.

2. As a preliminary measure, ie in the state of construction, the platform is installed in advance at a provisional location. Later, the same system is installed in the final state and remains there.

3. As a temporary platform extension. This is necessary, for example, if a longer track is ordered from the station provider for a limited time.

The dimensions of the makeshift platform are variable. Its width is preferably between 2.40 m and 3.00 m. The length is preferably between 6 and 9 m, so that this system also minimizes costs and can be worked with simple device technology. Since the Makeshift platform to be installed several times at different locations, usually only certain grids are used.

The makeshift platform consists of precast foundations 4 and a precast slab 1, which is supported on these foundations and is secured with stainless angles 61 against unintentional lateral displacement. The overhanging part can be varied as in the other systems. The precast foundations sit on a ballast bed and a thin layer of sand. Since the edges of the temporary restorations are straight, profiled sheets made of galvanized steel or stainless steel are provided on the floor, which cover the expansion joint. In a straight position, this joint is permanently elastic.
Railings and lighter platform structures can be mounted on the outer edge using stainless steel brackets. As a rule, lighting masts etc. must be set up separately behind the platform edge. The cables are routed above the free space under the platform slab. In this case, recesses for empty pipes must be provided in the foundations. In order to ensure the height adjustability, there is the possibility of providing a precast intermediate piece 3, the bearing surface of which is not allowed to be larger than the original supporting surface of the precast concrete slab, so that the loads go vertically from the slab into the foundation (supporting surface approx. 20 cm) ,

FIG. 19 shows a perspective view for better illustration a central platform of the type described above.

The arrangements described by way of example in the figures can be used achieve numerous advantages over the known systems:

When renovating conventionally built platforms with the System platform according to the invention can the old platform edges and the backfill is largely left in place, great Avoid mass movements and save expensive landfill fees. The system platform is moved into the Business breaks with two-way system vehicles or cranes assembled and can can be used immediately. The system enables preparatory work for Production of the platform, e.g. Civil engineering, foundation manufacture, if no rail transports are required outside the printing area of the adjacent track. This can save operational costs and slow driving points are minimized. When changing the horizontal and / or vertical position of the platform, all parts can be reused become.

The system platform is based on a modular precast skeleton, with which, in an extremely short construction time, a new modern platform over one damaged platform or above the earth next to the formation can be installed.

By installing or removing prefabricated spacers, the Platform height between 38 cm above sea level (above the top of the rail) and 96 cm above sea level can be varied in stages at any time without great effort.

The color, structure and texture of the surface of the covering can be discussed with the customer Bauherm individually defined and manufactured in consistently high quality become.

Due to the properties of the system platform, platform renovations can be carried out can be accomplished inexpensively without great effort. The old platform can be left in place, it is narrow at a distance of 5-8m To install trenches for the support bodies; overall there are only a few Mass movements and correspondingly low disposal costs that are not are only economically interesting, but also show that the System platform ecological advantages over conventionally built Has platforms. There will also be great flexibility for the future guaranteed. The panels are made with two-way system vehicles or profile-free Rail cranes moved, the spacers easily to the required level customized. In curved layers up to a radius of 300m, the Platform plates optimally adapted to the curvature, the entry is enables the passenger without gaping gaps. In the system platform can already have factory-made conduits for all types of cable routes, mounting sleeves for platform equipment elements as well as column foundations for Weather protection devices are incorporated. Latitude and longitude parameters are based on the use case and the existing ones Transport options tailored, or also to a given Grid dimension of the user.

Furthermore, larger structures such as Roofs or weather protection devices can also be integrated according to a user specification, either according to the detailed sketch by connecting the required foundations to the Base beams or as individual foundations through a recess in the system plate.

Due to the prefabrication of the system components, an extremely short construction time can be realized, the work can take place during the breaks, it is not necessary to set up a La point.
There are various design options for the execution of the textures and patterns for the surface of the covering, which also applies to the choice of equipment.
It is also possible to integrate automatic defrosting systems based on electrical floor heating or to use the space under the system platform as a bike & rail station with lockable bicycle boxes, as a place for luggage storage, etc.

Existing or planned deep drainage systems on neighboring tracks. become individual through recesses in the foundation of the platform considered.

Standard traffic loads of 5 kN / m ² for passenger traffic and 5 kN / m ² for a 3-t baggage vehicle according to DS 804 Para. 105, Vol. 29 of DB AG can be used as load factors. The introduction of punctiform special loads, e.g. for supports for weather protection devices, etc. are possible and are permitted to a large extent without changing the planning.

All components comply with the regulations and provisions of DIN 1045 and ZTVK 88 manufactured accordingly and are frost and de-icing salt resistant.

Security and control systems are both compliant with German laws even according to the strict American standards like the American Blind Act (ADA) and the Blind Council (ACB). When accessing the system platform are ramps according to DIN 18024 for wheelchairs instructed passengers as well as bicycle troughs Stairways to make it easier to take bicycles with you and that to promote environmentally friendly bike & ride and bike & rail behavior.

An essential component for the system platform of system I can be a special precast reinforced concrete can be used, which is in the construction based on the static system of a π plate.

By choosing one for industrial buildings and residential construction extremely successfully used component can be placed on a beam support to be dispensed with. Manufacturing costs and installation effort can be minimized become.

Panel thickness (or web height for system I) of the system panel are for everyone sufficiently conceivable operating conditions. Weight and Dimension of the element are on the work equipment in railway construction and that existing clearance profile matched.

In systems II, III, IV, the plates are placed one below the other in the middle of the plate cantilevered area connected accordingly to height differences caused by bending or manufacturing, to compensate permanently.

Precast elements made of reinforced concrete are also used as support elements, with a gradual height adjustment from 38 cm above sea level up to 96 cm üSO is guaranteed.

The actual foundation is made of in-situ concrete. The dimensions of this Construction pits to be produced are generally chosen so that the stability the ballast bed is not endangered and no shoring is necessary.

Removable connections guarantee a problem-free and quick conversion in the event of a future change in level.
The transport anchors usually arranged in the surface of finished parts are avoided here in order not to disturb the uniform appearance of the surface by moving the plates with bands.

The foundations are dimensioned so that the permissible ground pressure according to DIN 1054 or Eurocode 7 is observed. In the case of particularly bad ones Soil stabilization is provided in individual cases or a deep foundation is necessary.

Basically all desired surface structures can be realized.
At the request of the user, the covering side, especially along the track side, must be equipped with a sure-footed, rough structure and a guide marking must be provided, which is indispensable as a visually and tactile orientation aid for special groups of people. A special surface quality, which is characterized by a high abrasion value and insensitivity to environmental influences and the use of thawing agents, is particularly preferred.

With this platform there is no additional work step in the production of the Surface required. Different colors, Structures, grids, coverings made to order by the user become. The necessary construction joints (e.g. to add different colors separate) are poured with non-shrinking mortar, so that no loss the statically required covering of the reinforcement of at least 3 cm arises. This is necessary in order to increase the panel thickness, and thus the weight minimize. This version can be sanded in color adapted to the colors of the surface.

example

for the area of the platform edge a 30-50 cm wide strip with a particularly non-slip structure (e.g. quintet pattern, checker plate pattern, other shapes), for the tactile guiding strip a 25 cm wide guide marking with a signal color, e.g. Knob structure according to ADA and ACD, for the platform Pavement structure, various variations possible.

The drainage is collected in a drainage channel and either fed to the ground in a septic tank or discharged into the sewage system.
A cross slope of 1-2% of the system platform to the side facing away from the track or (as a rule) to the center reliably ensures that the water flows off evenly.
In the case of different heights of the two tracks leading along the central platform, a uniform gradient to the central drainage is ensured by the plate widths being able to be varied so that a uniform gradient is maintained from both sides.

In a further embodiment, the water can through a special negative profiling of the plate surface in one or more Points are collected centrally and fed to a drain line.

The platform system allows free access to the Cavity under the platform, e.g. via a manhole. in the Manhole cover the surface structure is continued.

The cable routing takes place via cable protection tubes integrated in the plate System I, or through empty pipes arranged under the plate in the other systems. With cable connection boxes at regular intervals an uncomplicated supply of the platform facilities is guaranteed and enables the subsequent pulling in of cables.

Depending on the type and diameter of the cables, many cables can be pulled into the plate. A cable trough can optionally be installed in the space under the plate, in which additional lines can be accommodated, for example, for the installation of a parallel communication network.
At the same time, the cavity under the platform slab can accommodate cable guides. The cavities can be made accessible through doors or openings in order to use these spaces as storage space for winter maintenance, for example.

In the case of route electrification, the platform slabs and the Equipment elements in accordance with the provisions and notes of DIN 57 115 Part 1 (VDE 0115 Part 1) grounded via connection sockets on the rails.
