Description

The present invention relates to a rail storage device for sound-absorbing storage and fastening of a rail, with a ribbed plate for arranging the rail on an upper side of the ribbed plate, a first damping means and a frame. The first damping means can be designed as an elastomer bearing and is arranged between the ribbed plate and the frame for damping the ribbed plate.

Rail fastening systems of the aforementioned type are known in practice. A particularly well-known type of such a rail support system is the so-called "Cologne Egg". The "Cologne Egg" refers to a rail fastening that reduces structure-borne noise. Structure-borne noise, in turn, is the cause of secondary airborne noise in buildings next to or above railway lines. The name "Cologne Egg" is derived both from the oval shape of the rail support system used in practice and from the city name Cologne, since this type of fastening was first developed and used in Cologne.

With regard to how the “Cologne Egg” works, it is important to note that DE 28 32 989 C2 which describes the functional principle of the sound-absorbing rail mounting. The basis for this sound-absorbing rail mounting is that in the DE 28 28 714 A1 described device for the sound-absorbing storage of heavy components.

Both the rib plate and the frame can be made of metal, these two metal parts being connected to one another by vulcanization, namely through or via the first damping means.

Tabs with holes can be provided on the frame for fastening to the surface using sleeper screws or threaded pieces. The rib plate can be supported by the first damping means, which can preferably be designed as a vulcanized elastomer. The first damping means can in turn be supported on the frame. Such a structure of the rail storage device causes vertical forces to be divided into thrust-pressure components. The acoustic effectiveness of the so-called “Cologne Egg” is based on this.

The construction of the rail storage device of the “Cologne Egg” type known from practice has a maximum construction height of at least approximately 76 mm. For the purposes of the present invention, the construction height is understood to be the distance from the underside of the frame to the top of the ribbed plate, whereby the ribs or the height of the ribs of the ribbed plate are not taken into account when determining the construction height. Since it is also known from practice that the top of the ribbed plate runs obliquely to the ground and/or obliquely to the underside of the frame, the maximum installation height is understood to mean the installation height at the highest point on the top of the ribbed plate.

However, in practice, this installation height of the "Cologne Egg" results in the problem that the "Cologne Egg" cannot be easily integrated into existing rail bearing systems, as these often require a lower installation height. In practice, therefore, when using the "Cologne Egg" it is regularly necessary to work on or remove the subsoil in these sections when integrating the "Cologne Egg" so that the installation height of the "Cologne Egg" is compensated. This process is not only time-consuming, but also generates high commissioning costs for the "Cologne Egg".

The object of the present invention is to avoid the aforementioned disadvantages of the prior art or at least to substantially reduce them.

The aforementioned object is achieved according to the invention by a rail storage device for sound-absorbing storage and fastening of a rail according to claim 1.

According to the invention, the rail support device has a ribbed plate for arranging the rail on an upper side of the ribbed plate. To arrange the rail on the upper side of the ribbed plate, the ribbed plate can have at least two ribs between which the rail can be enclosed. According to the invention, the rail support device further comprises a first damping means, which is designed in particular as an elastomer bearing or as an elastic bearing, in particular a rubber-elastic bearing. In addition, the rail support device comprises a frame, which delimits the rail support device in particular on the outside. The first damping means is between the ribbed plate and the frame. In particular, the first damping means separates the ribbed plate from the frame, preferably completely and/or circumferentially.

Furthermore, it is provided according to the invention that a further damping means is provided below the ribbed plate to limit deflection.

The further damping means can be provided and provided separately from the first damping means. However, in further embodiments according to the invention it is also possible for the further damping means to be connected to the first damping means.

The additional damping means is designed in particular in such a way that a deflection limitation can be ensured. In the prior art, the suspension or damping of the "Cologne Egg" is only provided by the first damping means. Due to the arrangement and design of the first damping means in the prior art, a certain height and width of the first damping means must be provided so that the damping properties required to reduce structure-borne noise can be guaranteed. According to the invention, it is now possible for not only the first damping means to be provided to reduce structure-borne noise and to limit deflection. The additional damping means can then also contribute to the damping properties or at least partially ensure them as well.

According to the invention, this results in the significant advantage that it is possible to reduce the dimensions, in particular the height and/or width or material thickness, of the first damping means - without, however, causing disadvantages with regard to the sound-reducing properties of the "Cologne Egg". According to the invention, the structure-borne sound reduction achieved by the known "Cologne Egg" can be maintained or even improved.

By providing an additional damping means, the invention provides the essential advantage that the installation height can be significantly reduced compared to rail bearing devices of the "Cologne Egg" system known from the prior art, preferably by at least 10%.

Such a reduction in the installation height also has the advantage that it is possible to use rail storage facilities according to the "Cologne Egg" system. also in sections and/or areas that require a construction height of less than 76 mm due to the or an existing rail support system. Accordingly, complex processing of the subsurface can be omitted, so that the rail support device according to the invention can be used comparatively easily in existing rail support systems. This increases the flexibility of using the "Cologne Egg" and also creates the possibility of using the "Cologne Egg" in a large number of existing rail support systems, which was not possible before the invention due to the specified increased construction height of the "Cologne Egg" known from the prior art.

In this context, the deflection limitation ensures in particular that the ribbed plate can only be lowered to a certain height, which is understood according to the invention as deflection limitation. This distance or this variable height difference of the deflection limitation can arise on the one hand due to the material properties of the first damping means and/or the further damping means and on the other hand due to a distance between the underside of the further damping means and the ground.

Ultimately, with such a distance between the underside of the further damping means and the ground, this distance would first have to be bridged and then the material of the further damping means would have to be compressed. In this context, it is understood that the first damping means also provides corresponding damping when the ribbed plate is loaded and thus also ensures the suspension properties. Thus, the first damping means, in addition to the further damping means, also contributes in particular to limiting deflection.

According to the invention, in particular a deflection limitation in the range between 1 to 15 mm, preferably between 2 to 10 mm and in particular 4 mm +/- 1 mm, can be provided. On the one hand, such a deflection limitation enables effective and safe attenuation of structure-borne noise and thus contributes to the stability of buildings that are arranged near the rail. However, an arbitrarily high level of suspension is not guaranteed; rather, the deflection limitation makes it possible to reduce this deflection to levels that have proven successful in practice.

Accordingly, according to the invention, the rail mounting device can be used with the same or improved structure-borne noise reduction properties as the "Cologne egg" known from the prior art, but in particular ensure a lower installation height.

The rail support device according to the invention is preferably particularly easy to integrate into existing rail systems. In this context, it has proven to be particularly advantageous if the additional damping means, the first damping means, the ribbed plate and the frame are firmly connected to one another, in particular in a materially bonded manner, preferably by vulcanizing the damping means. This enables this structural unit to be handled as a compact, coherent structural unit, so that errors in the assembly of the rail support device can be avoided.

The frame preferably has a recess for arranging the first damping means and the rib plate. The recess can be designed as a breakthrough. In particular, the recess serves to accommodate the first damping means, in particular wherein the first damping means rests all around on the inner wall of the recess, is preferably firmly connected to it, is preferably vulcanized onto it. Such vulcanization makes it possible to handle the frame and the first damping means as a common assembly, as already explained at the beginning.

In a particularly preferred embodiment of the present invention, it is provided that the additional damping means adjoins the underside of the ribbed plate, in particular rests against it and/or is connected to it. In particular, the additional damping means can be integrally connected to the underside of the ribbed plate. The additional damping means is preferably vulcanized to the underside of the ribbed plate at least in some areas, preferably completely.

Alternatively, it can be provided that the further damping means is intended to rest on the ground and is spaced from the underside of the ribbed plate. In such an embodiment, the overall deflection limitation achieved results, on the one hand, from the material of the damping means and, on the other hand, from the distance or gap between the top of the further damping means and the underside of the ribbed plate.

If the additional damping means is connected to the underside of the ribbed plate and/or arranged adjacent to it, the achieved deflection limitation results in particular from the distance between the underside of the additional damping means and the material properties of the additional damping means or the damping means, as already explained at the beginning.

Furthermore, in a preferred embodiment of the inventive concept, it is provided that the first damping means and/or the further damping means has an elastomer, in particular a synthetic rubber, and/or an elastic, preferably rubber-elastic, material as the material. A natural rubber (NR) can in particular be provided as an elastic, in particular rubber-elastic, material. The further damping agent preferably consists of natural rubber.

The provision according to the invention of the first damping means and the further damping means results in the possibility of being able to individually adjust the damping or suspension properties of the rail storage device to different applications. Such an adjustment can also be made through the choice of material for the damping means.

In this context, different combinations are possible, which ensure a high degree of flexibility in the possible damping when using the rail bearing device.

The materials of the first damping means and the further damping means can therefore be at least essentially the same. Alternatively, it is also possible for the first damping means to have a material that is different from the further damping means. For example, the first damping agent could have an elastomer, in particular a synthetic rubber, whereas the further damping agent could have a natural rubber as a material. Different additions of the materials are also conceivable according to the invention for the first and the further damping means.

Preferably, the first damping means has at least substantially the same hardness or a different hardness compared to the hardness of the further damping means. By adjusting the hardness, that specific damping properties of the first and the further damping means can be guaranteed and thus used - in each case for the optimal application and for improved bearing of the rail.

Particularly preferably, the additional damping means has a Shore hardness A (in particular according to DIN EN ISO 868 and/or DIN ISO 7619, as of September 2022) between 40 and 80, preferably between 45 and 50 and in particular 50 +/- 20%. The aforementioned Shore hardnesses enable a rubber-elastic design of the additional damping means and at the same time also a deflection limitation for the ribbed plate.

The aforementioned damping properties of the first and further damping means make it possible to provide the particularly advantageous properties of reducing structure-borne noise through the "Cologne Egg" also in the rail storage device according to the invention, which is preferably to be viewed as a further development of the "Cologne Egg".

Preferably, a recess is provided on the underside of the ribbed plate for receiving the additional damping means. In particular, the recess is designed such that when the rail support device is not under load, the underside of the additional damping means is spaced from the substrate or a gap is provided, preferably by at least 0.5 mm, preferably between 1 and 10 mm, more preferably between 1.5 and 2.5 mm.

It can be provided that the recess is designed to be complementary - in terms of dimensions - to the additional damping means. The additional damping means preferably protrudes at least partially beyond the recess and thus beyond the ribbed plate.

The further damping means can in particular at least substantially completely fill the surface of the recess of the ribbed plate.

The recess can be provided in particular by appropriate machining of a ribbed plate already known from the prior art and thus enables the adaptation of a known ribbed plate for use in a rail bearing device according to the invention. Ribbed plates with a corresponding recess can already be manufactured during production.

In a preferred embodiment, the further damping means has a plurality of projections, in particular designed as knobs. In particular, the projections can protrude or protrude from a base surface facing the underside of the ribbed plate. The projections can in particular protrude beyond the recess.

Alternatively or additionally, it can be provided that the projections are at least partially, preferably completely, designed as solid bodies. The design as a solid body enables the damping properties to be optimally provided for the rail storage device.

The design of the projections makes it possible, in particular by spacing the projections from one another, that when the ribbed plate is subjected to a corresponding load, the projections can be compressed and enable a corresponding load transfer, in particular when the underside of the projections already hits the ground or when the top of the base surface hits the underside of the rib plate. Whether the underside of the projections abuts the ground or the top of the base area abuts the underside of the ribbed plate depends on whether the base area is firmly connected to the underside of the ribbed plate or not. The projections and their spacing from one another thus ensure that the material expands accordingly under load and can provide the deflection limitation according to the invention, in particular without causing material stress on the ribbed plate or the frame.

Preferably, the projections can also be firmly connected to the base plate and/or formed as one piece therewith.

The projections can be essentially identical in construction or different from one another. An identical arrangement makes it possible to produce the additional damping means in a comparatively simple and cost-effective manner and to ensure optimal damping properties.

In particular, the substrate is formed by the plane spanned by the underside of the frame facing away from the rail - especially in the unloaded state of the rail bearing device.

Preferably, the additional damping means has between 2 and 30, more preferably between 3 and 20, preferably between 4 and 10, projections. Alternatively or additionally, it can be provided that the projections extend over at least 10%, preferably between 10% and 90%, more preferably between 20% and 40% and in particular between 30% and 70% of the surface of the base area. The fact that the projections do not extend over the entire surface of the base area also ensures that the projections are spaced apart from one another. The distance between two immediately adjacent projections can vary and can be provided in particular according to the desired damping properties.

In a particularly advantageous embodiment of the invention it is provided that the projections have an at least essentially cylindrical and/or at least essentially a conical, preferably frusto-conical, shape. The conical shape has the advantage that excessive widening can be counteracted when the projections are loaded with a corresponding material expansion. Ultimately, in connection with tests carried out when the invention was created, it was found that the conical shape ensures the optimal damping properties of the further damping means when used for the rail storage device. In this context, it can be provided that the projections taper conically starting from the base area towards the underside of the further damping means, which faces the ground. Accordingly, the outer diameter of the projections in the area of the subsurface or facing the subsurface can be smaller than the outer diameter of the projections in the area of the base surface. This makes it possible for material expansion of the projections to be compensated for when the projections are loaded.

It can preferably be provided that the damping means has projections arranged in rows, whereby projections can also be arranged outside a row. In particular, projections arranged in a row can be at least essentially the same distance from one another. Alternatively or additionally, it can be provided that if there are a plurality of rows, the rows are equally spaced from each other. It can also be provided that, for example, at least three projections are arranged in at least two rows and further projections are provided outside of these rows, in which case, in particular, a constant distance is not included between each pair of immediately adjacent projections. Ultimately, the projections can be arranged on the base surface in such a way that optimal damping behavior of the further damping means results.

The thickness of the base area can also be provided depending on the height of the projections. The material thickness of the base area of the further damping means can correspond to at least 1%, preferably between 1% to 60%, more preferably between 5% to 20% and in particular between 10% to 15% of the maximum height of the projections. The material thickness of the base area can in particular be at least essentially constant. The aforementioned relationships between the material thickness of the base area and the height of the projections make it possible to adapt the deflection limitation to the needs and requirements in the respective installation situation.

In a particularly advantageous embodiment of the present invention, the rail storage device has a maximum installation height of at least 40 mm, preferably between 40 to 70 mm, more preferably between 50 to 60 mm. The installation height can be provided according to customer specifications. As explained above, the installation height in this context is determined by the distance between the bottom of the frame and the top of the ribbed plate (except for the ribs of the ribbed plate).

Furthermore, it goes without saying that the top side of the ribbed plate in the assembled state can also run obliquely to the ground and/or obliquely to the underside of the frame. In this context, the maximum installation height means the greatest height.

In particular, it can be provided that the minimum installation height (i.e. the lowest installation height) in the assembled state is at least 30 mm, in particular between 30 and 60 mm, more preferably between 40 and 50 mm. The distance between the minimum and maximum installation height can vary depending on the size or length of the rail support device. In particular, a Distance of at least 5 mm, preferably between 5 and 15 mm, more preferably between 6 and 10 mm, can be provided. The angle of inclination between the top of the ribbed plate and the base or the bottom of the frame can be at least 0.5°, preferably between 0.5° and 3°, more preferably between 1° and 2° and in particular 1.4° +/- 15%.

In a further preferred embodiment, it is provided that the first damping means extends with a support section over the height of the frame. In particular, the first damping means extends from the top of the frame to the bottom of the frame and also particularly preferably rests with the support section on the ground. The first damping means preferably protrudes from the top opposite the frame.

Furthermore, the support section can be supported on the top of the frame and/or at least partially rest directly on the top of the frame. This makes it possible to introduce the forces that occur when the ribbed plate is loaded into the frame and via the frame into the ground. The first damping agent also dampens the load on the ribbed plate and leads to a reduction in structure-borne noise.

Preferably, an arrangement section of the first damping means is provided which is adjacent to the support section. The arrangement section can be spaced apart from the underside of the support section and have a receptacle for arranging the ribbed plate. In particular, the arrangement section protrudes from the support section on the upper side and/or the underside of the further damping means protrudes from the underside of the arrangement section.

The ribbed plate preferably has a circumferential support region on the edge, wherein the support region is arranged in the receptacle of the arrangement section of the first damping means. In particular, the support region of the ribbed plate encloses the recess of the ribbed plate. The support region can thus enable the transition between the first and the further damping means that are arranged in the recess.

In a further advantageous embodiment, it is provided that the inner longitudinal side of the frame facing the first damping means or the The inner wall of the frame and/or the outer longitudinal side of the first damping means facing the inner longitudinal side of the frame lie directly against one another and/or run at an angle α of 40° to 85°, preferably 70° to 80°, to the underside of the frame. The aforementioned angle enables the forces occurring during loading to be optimally introduced into the frame and the subsurface and no undesirable tensions arise in the entire rail bearing device. If the angle α were to be formed at a right angle, there would be a disadvantageous dissipation of the forces, whereby the oblique arrangement enables the forces to be introduced into the subsurface in an efficient manner. The angle α faces away from the ribbed plate, so that it is understood that there is a further angle (180° - α) between the inner longitudinal side of the frame facing the first damping means and/or the outer longitudinal side of the first damping means facing the inner longitudinal side of the frame to the underside of the frame, which faces the ribbed plate. The angle α is preferably at least substantially constant all the way around the frame or all the way around the ribbed plate.

It is preferably provided that the longitudinal section of the inner longitudinal side of the first damping means facing the ribbed plate and/or the outer longitudinal side of the ribbed plate facing the first damping means is arranged at an angle β of 40° to 85°, preferably from 70° to 80°, runs/runs towards the underside of the frame. Like the angle α, the angle β also enables the aforementioned advantageous properties when loading the rail storage device. It is preferably provided that the angles α and β are at least essentially the same size, which enables the symmetry of the rail storage device and can ensure an optimized introduction of force.

It is also preferably provided that the first damping means completely delimits the ribbed plate from the frame on its circumference. The first damping means can also be designed to run all the way around the ribbed plate.

Advantageously, the rail can be fastened to ribs of the ribbed plate, preferably using appropriate clamps and threaded screws. Clamping devices, in particular clamps, can be provided for fastening the rail, which can be connected by appropriate connecting means, such as for example threaded screws, can be firmly connected to the ribbed plate, whereby the rail is clamped to the ribbed plate.

The frame, in turn, can be firmly screwed or force-fitted to the substrate using appropriate connecting elements, in particular threaded screws.

In addition, it can be provided that the frame and the damping means completely enclose the ribbed plate circumferentially.

In a further preferred embodiment, it is provided that the ribbed plate and/or the recess and/or the first and/or the further damping means have an oval shape in cross section, in particular the shape of an ellipse. In particular, the longitudinal axis of the ellipse of the ribbed plate, the recess and/or the damping means is arranged at least substantially at a right angle to the longitudinal axis of the rail.

The respective longitudinal axis results at least essentially in the direction of the largest longitudinal extent of the respective body.

An orthogonal alignment of the longitudinal axis of the ellipse and the longitudinal axis of the rail makes it possible to arrange the rail on the rail bearing in such a way that the optimal damping properties can be provided and the rail is stored safely and permanently.

Furthermore, according to the invention, the object can be achieved in particular in that the first damping means extends with a support section over the height of the frame to the underside of the frame to rest on the ground. This inventive idea is proposed in particular independently of the further damping means to solve the problem according to the invention. A direct arrangement of the first damping means on the ground makes it possible to directly introduce the forces to be cushioned when the ribbed plates are loaded into the ground via the first damping means, which increases the flexibility of use and also reduces the structural height of the entire rail storage device.

It is not known from the prior art that the first damping means extends to the underside of the frame or to the ground in the unloaded state of the rail storage device. All that is known from the prior art is that the first damping means hits the ground when there is already a load on the ribbed plate to be cushioned or dampened in the assembled state.

In this context, it is understood that the second embodiment of the rail support device according to the invention can particularly preferably be provided in combination with at least one of the previously mentioned embodiments. Reference can therefore be made to the aforementioned advantages and preferred embodiments, which can also apply to the further embodiment of the rail support device according to the invention, without this requiring further explicit mention.

Ultimately, the arrangement of the first damping means on the subsurface in the installed state of the rail storage device has an independent meaning according to the invention. This makes it possible to provide a larger amount of material for the first damping means, without having to significantly increase the height of the entire rail storage device. This makes it possible to reduce the installation height. Furthermore, the damping properties of the rail storage device and in particular of the “Cologne egg” can be optimized.

Furthermore, it is expressly pointed out that all of the above and following intervals include all of the intermediate intervals and also individual values contained therein and that these intermediate intervals and individual values are to be regarded as essential to the invention, even if these intermediate intervals or individual values are not specifically specified in detail.

Further features, advantages and possible applications of the present invention emerge from the following description of embodiments with reference to the drawing and the drawing itself. All described and/or illustrated features, individually or in any combination, form the subject matter of the present invention, regardless of their summary in the claims or their reference back to them.

a schematic perspective representation of a further embodiment of a ribbed plate according to the invention.

Fig. 1 shows a rail storage device 1 for sound-absorbing storage and fastening of a rail 2. The rail storage device 1 has a ribbed plate 3, which includes two ribs 28 in the exemplary embodiment shown.

The rail mounting device 1 further comprises a first damping means 6, which can in particular be designed as an elastomer bearing, and a frame 7.

The Fig. 2 shows a schematic top view of a rail storage device 1. From the Fig. 2 it can be seen that the first damping means 6 is arranged between the rib plate 3 and the frame 7.

The ribbed plate 3 serves to arrange the rail 2 on an upper side 4 of the ribbed plate 3.

In the in Fig. 1 In the exemplary embodiment shown, the rail 2 is firmly attached to the ribbed plate 3, in particular braced. For this purpose, tension clamps 29 can be used, which are firmly connected to the ribbed plate 3 via threaded screws 30, which can be fastened with a nut 31. This is also evident from the schematic perspective view of the rail storage device 1 according to Fig. 13 and 14 visible.

In the Fig. 13 a schematic representation of the braced rail 2 on the ribbed plate 3 is shown. To accommodate the threaded screw 30 and to arrange the tension clamps 29, the ribs 28 of the rib plate 3 can be perforated, as is the case Fig. 16 shows. The breakthrough can be realized via an opening 39, whereby the opening 39 can be used to arrange tension clamps 29 and threaded screws 30, as shown in the schematic perspective view of a ribbed plate 3 Fig. 16 clarified.

Ultimately, the rail 2 is attached to the rail storage device 1 with its longitudinal axis G. It can be provided that the longitudinal axis L of the rib plate 3 runs at least substantially orthogonally to the longitudinal axis G of the rail 2. This is schematic in the Fig. 2 shown.

The Fig.2 clarifies that the first damping means 6 circumferentially delimits the ribbed plate 3 at least substantially completely from the frame 7. In this case, a direct contact of the frame 7 with the ribbed plate 3 can be prevented by the arrangement of the first damping means 6.

In addition, the first damping means 6 can be firmly connected to the frame 7 and/or the ribbed plate 3, preferably in a material-locking manner, in particular vulcanized. The design of the first damping means 6 as an intermediate layer between the frame 7 and the ribbed plate 3 is also shown schematically in the Fig.7 and the Fig.9 and the Fig. 11 particularly clearly.

The Fig. 3 to 6 show a further damping means 8. The further damping means 8 is located below the ribbed plate 3 to limit deflection in a rail storage device 1 according to the Fig. 1 arranged. Accordingly, the further damping means 8 is in the Fig. 1 and the Fig. 2 not visible, since this is ultimately arranged below the rib plate 3. The arrangement in this regard is shown schematically by using dashed lines Fig. 8 shown and results from a corresponding bottom view of the rib plate 3, as shown schematically in the perspective view Fig. 15 is shown.

From the to the Fig. 7 , 9 and 10 The respective cross-sectional views shown also show the arrangement of the further damping means 8 below the ribbed plate 3.

It is understood that the further damping means 8 in the installed or built-in and/or mounted state is at least substantially completely covered on the upper side by the ribbed plate 3 and/or enclosed by the ribbed plate 3.

For the arrangement of the further damping means 8, the ribbed plate 3 can have a recess 21. The further damping means 8 can at least substantially cover the surface on the underside 5 of the ribbed plate 3 in the region of the recess 21 and/or completely abut the inner wall of the recess 21, as can be seen from the schematic perspective view of the Fig. 15 - but also from the Fig.7 - emerges.

The rail storage device 1 can be arranged on a surface 37. The frame 7 can rest at least essentially directly on the substrate 37. When installed, the ribbed plate 3 is spaced from the substrate 37, as shown schematically in FIG Fig. 7 and 9 becomes apparent.

What is not shown is that in a further embodiment the further damping means 8 is provided for resting on the surface 37 in the unloaded state, wherein a distance between the further damping means 8 and the underside 5 of the ribbed plate 3 can be provided to limit deflection.

The frame 7 can be connected to the base 37 via frame fastening means 35. For this purpose, appropriate screws or the like can be used for the fixed arrangement.
