Description

The invention relates to a platform according to the preamble of claim 1.

Stops for rail-guided wheeled vehicles have platforms, the distance and height of which is precisely defined relative to the track, in order to make it easier for passengers to get in and to allow the trains to pass smoothly. Such platforms (DE-OS 20 35 332) are built, for example, as earth or stone walls closed off from c-shaped platform edges to the track with stone paving as a walking level. Depending on the function, cable ducts run under the running levels in molded blocks or in the floor. C-shaped platform edges (DE-OS 33 17 207) serve as escape niches for marshallers.
To protect passengers against electric shock, grounding cables can connect all metal components of the platform.
This design is very expensive and, above all, time consuming. When building new platforms, the neighboring tracks must therefore be blocked several times for a long time. In addition, the plaster must be broken up for cable work and the mechanical maintenance of the track body is hampered in part by the shape of the platform edge.

In addition, a maintenance-intensive, entirely made of steel parts stop is known (US-PS 18 70 638).

The invention is therefore based on the object of proposing a platform that can be produced very quickly and inexpensively, requires a short blocking time for the tracks and enables necessary repair work and retrofitting on or under the entire platform without earthworks, offers an escape niche for marshalling and mechanical Work through the tracks in the station.

The object is achieved by claim 1. Subclaims contain advantageous developments of the invention.

From a kit prefabricated in the supplier workshops, essentially consisting of concrete bases, which are pre-defined If a grid spacing is placed on the leveled ground, longitudinal members to be fastened on it made of steel profiles or reinforced concrete and these longitudinal members transversely overlapping and protruding running plates, a simple hollow structure is put together. After this pre-assembly on the construction site, the still exposed connecting elements on the parts of the kit are cast, so that there is a firm bond between the parts.

The platform can consist of rows of running plates lying next to each other on two longitudinal beams or two of these rows on four parallel longitudinal beams. The supports and plates of this double-row platform also have the same grid dimensions.

The joints between the running plates have recesses that are locked by a cement seal. The joint is then potted with elastic material in order to obtain a flat running surface.

For platforms in track curves, the concrete base and side members of the standard grid can be used; only the running plates are already adapted to the specified curve radius on the head sides in the manufacturing plant.

The hollow platform body to be built in this way has, in addition to an extremely short blocking time of around 70 hours during the delivery and construction phase, a number of other advantages: the entire space under the running plates can be entered through inspection holes contained in the running plates for inspections or - this is very essential - Can be used to install cable ducts or pipes. Subsequent work on the lines is very simplified. The escape niche for railway workers is preserved by the cantilever of the running plates over the side members. However, the double disadvantage of the previous c-shaped platform edges is avoided. Thanks to the C-shape, the base hindered the working of the ballast of a track bed down to normal depths of 60 to 70 cm with the help of automatic bed cleaning machines. On the other hand, the drainage of the track had to be placed in the middle of the track. These problems are solved by the larger distance of the concrete base according to the invention from the track.

Instead of the prefabricated concrete base, an in-situ concrete base can also be used can be applied without leaving the scope of the invention. This is sometimes necessary, especially on platforms with a slope, but increases the blocking times for the track to around 100 hours. However, this is still much less than with previous construction methods.

The drainage of uncovered platforms takes place through channels in the running level. For this purpose, a slope is created by shaping the top of the running plate accordingly. In the running level of the platform formed from a row of running plates, these running plates have cutouts in the form of a channel according to the invention. In the case of double-row platforms, the butt joint of the running plates in the middle of the platform is used as the drain. The butt joints have cutouts for a grating cover on the top of the running plates. For safety reasons, the paving of the platforms has already been inclined towards the center of the platform to prevent luggage trolleys or prams from rolling onto the platform.

The surfaces of the running plates can already be factory-made with a non-slip structural concrete with grooves or other regular or irregular deepening patterns, so that no reworking on the running level of the assembled platform is necessary. Furthermore, the surface of the concrete of the running plates can already be colored in the factory. This coloring can consist of markings for parking spaces, platform edges or arrows or the running level of the platform can be colored overall.

Part of the kit is a reinforcement that runs through the running plates and a metal profile that connects this reinforcement as edge protection of the running plates towards the track. This edge protection is usually made of sheet steel and is screwed onto the rest of the reinforcement in an electrically conductive manner using standard bushings.

To dampen sound vibrations, a soundproof wall running parallel to the track can be attached to the side members, the concrete base or the running plates in order to reduce driving and braking noises caused by the railroad operation. The soundproofing can be created by conventional lightweight assembly walls or by green trellis.

Furthermore, in order to avoid structure-borne noise or undesirable component vibrations caused by periodic loading of the running plates, a strip-like, elastic vibration damper, for example made of rubber, can be inserted between the longitudinal beams and the running plates.

The simplest installation of lines for electricity, water, compressed air, etc. enables cable carriers suspended from the running plates or standing on the concrete bases in the form of sheet metal cable ducts or pipe carriers. The precautionary introduction of empty pipes or the subsequent burying of lines is unnecessary, as is customary in the prior art.

The prefabricated kit can also have recesses, openings or pocket-like depressions in the running plates, which are used to insert supports for grids, benches, vending machines or the like. The same applies to the concrete base, which has quivers in its middle section for inserting a support for a platform roof.

In addition to a track S lying in the ballast bed 8 with a drainage device made of drainage film 10 and drainage 9, a bored pile 11 has been driven into the ground on a slope 12 (FIG. 1). On the bored pile 11 rests a concrete base 23 which is U-shaped with two bumps 3, 22. On the cusps 3, 22 there are two concrete beams 2, 24 at a distance of about 1.50 m and, with interposed, vibration-damping rubber strips 15, running plates 1 with a dimension of 3.5 m length x 2.5 m width (Fig. 2). The beams 2, 24 have a grid length of 5 m. The running plate 1 forms a kind of roof for the cavity 49, which is accessible from the entrance 16 with a cover 17 and contains a cable duct 14. The running plate 1 extends beyond the concrete beam 2 to the track S by about 1 m and thus forms an escape niche. The cavity 49 is laterally enclosed by a soundproof wall 4 and a trellis 13 with greenery. The running plate 1 has an edge protector 5 which is electrically connected to a reinforcement (not shown) in the running plate 1 and is screwed to the running plate 1. The surface of the running plate 1, the running level 7, has a gradient G of 2% to the drainage channel 18 as well as a warning marking 6 and a red coloring (not shown) of its non-slip groove structure. The coloring is deceptive to the surface of the brake pads of the rail vehicles. In addition to the drainage channel 18, the running plates 1 have bearing edges 19 for supports 20 of a weather protection 21 with banks 7, grilles 73 and waste paper bin 68 (FIG. 2).

In longitudinal section it can be clearly seen that in the grid shown here two running plates 1 are assigned to a concrete beam 24. The concrete beams 24 have at their ends shoulders 29, with which they rest on the humps 22, the concrete base 23 arranged at a 5 m distance corresponding to the length of the beam, and are fastened via anchor bolts 28. The joints 26 between the running plates 1 have cutouts for component connectors 27. In the cavity 49, the cable duct 14 is held securely by suspension 25.

Fig. 3 shows the fastening situation of the concrete beams 24 to the humps 22 and the running plates 1 with each other and on the concrete beams 24 in a somewhat enlarged section. In the manufacture of the concrete base 22 anchor bolts 28 were inserted into the humps, onto which the concrete beams 24 with recesses 32 were put during assembly on the construction site after a joining layer 33 which compensated for the manufacturing tolerances was placed on the humps 22. The recesses 32 were then filled with potting compound 72. The same applies to the running plate 1 with recesses 30 for the anchor bolts 31 in the concrete beams 24 after Rubber strips 15 were inserted.

The joints 26 between the running plates 1 have recesses 27 into which a cement seal 74 is inserted before the joint 26 is filled with potting compound 72 from above. The cement seal 74 prevents a vertical offset of the running plates 1 to one another.

All parts of the kit for the platform were delivered by rail wagons and railway crane wagons over the track during short breaks. This applies equally to the double platforms shown in FIGS. 4 and 5 for two tracks to the left and right of the platforms, of which only one track S is shown.

FIG. 4 shows an embodiment of the invention with a running plate 34 symmetrical to the center of the platform, the surface of which has a gradient G to the center of the running plate 34. The running level is formed by shaped stones 43 lying in the pavement bed 42, which are supported laterally by edge plates 35. The running plates 34 are fastened with anchor bolts 45 to steel beams 44, which in turn are bolted to the bumps 38, 63 of the concrete base 40 by anchor bolts 37.

The concrete base 40 rests on a break-proof foundation plate 41 at a distance of about 1 m next to the track S lying in the ballast bed 50. Soundproofing devices 36 prevent emissions of track S across the cavity 48. The cavity 48 is through entry 46 with cover 47 for inspection purposes accessible on the pipes 39.

FIG. 5 shows a double-row double platform constructed mirror-symmetrically to the center of the platform for track S in ballast bed 51 and another track, not shown. A concrete base 59 with bumps 58, 62 has been created on a cleanliness layer 61 in a formwork (not shown) at the construction site, on which steel beams 56 and in turn running plates 54 have been mounted. The running level 57 of the running plates 54 has a gradient G to the center of the platform, where water 64 can drain into the drainage 69 through recesses 65 covered with gratings 65.

The running plates 54, which, as shown in FIG. 2, rest in a grid-like manner on the standardized steel beams 56, also have an edge protector 52 which is electrically conductive with the reinforcement of the concrete of the running plates 54 is connected, and warning markings 53.

Soundproof walls 55 close the cavities 66, 67. The concrete base 59 guides a line carrier 70; it can be covered with earth 60 afterwards.
