Abstract

The invention relates to an elastomer support (10) for a support device (9) for cantilevered segments of an expansion joint in a roadway, especially of bridges with an elastomer element, whereby several elastomer layers (18), at least partially separated by reinforcing elements (17) are positioned in the direction of the main load of the elastomer support (10) and have a thickness (23) of only between 1 % and 20 % of the width dimension perpendicular thereto, preferably between 2mm and 10mm.

Description

The invention relates to an elastomer bearing and a bearing arrangement for slats for bridging an expansion joint between two components, in particular roadways on bridges, as described in the preamble of claims 1 and 18.

BACKGROUND OF THE INVENTION

In order to allow for the expansion of the dilatations between the two parts of the structure, for example the support and the supporting structure of the bridge, these dilatation joints are bridged by the lamellas used, in particular intermediate or intermediate lamellas. The number of slats running parallel to each other in the direction of the expansion joint, respectively. The slats running parallel to the load-bearing structure are determined according to the allowable area of the joint width variation and the permissible load of the individual slats. The maximum allowable joint width is generally defined by the specification in the breakdown or by means of relevant professional standards. However, these plates do not only transmit the loads due to the support or support operation. However, at the same time, a uniform distribution of the slats in the expansion joint is also ensured. Therefore, the same spacing between individual slats is maintained at different dilatation states of the building components.

According to CH 651 339 A, elastic inserts are arranged between the individual slats, which are placed either directly between the individual slats or on the crossbars firmly connected to the individual slats.

Furthermore, it is also known, independently of these tapered inserts to transmit the load acting on the slats, to these slats on the rails, which transmit the load to the support, respectively. The load-bearing structure and its adjustment by changing the joint width allow for even distribution of the slats over the width of the expansion joint.

Finally, it is also known from AT 397 674 B of the same Applicant that the elastomeric lamella supports consist of individual longitudinally inserted profiles of divided block bearings, which are supported on the edge of the joint or on the adjacent intermediate profile. By placing several such block bearings along the length of the slats, the load induced by the load is distributed, as is the tensile load when changing the distance between the individual center and / or the center. by means of interposed lamellas to several such block bearings as well. By elastically supporting these lamellas, both self-adjusting elastic block bearings can achieve both load transfer and maintaining an equal distance between the individual lamellas and require few mechanical parts. The elastomer bearing thus formed, respectively. however, the bearing arrangement does not satisfactorily address all practical applications.

Furthermore, the individual features of the different embodiments mentioned above may also represent separate solutions according to the invention.

280 / B

In FIG. 1 shows a device 1 for bridging the expansion joint 2 in the roadway 3 between the support 4 and the supporting structure 5 of the bridge 6.

This bridging device 1 consists of FIG. 1 of the side slats 7, located on the supporting structure 5 of the bridge 6, or on the support 4 of the roadway 3 and the middle and / or intermediate slats 8 located between these outer slats 7. These middle and / or intermediate slats 8 are supported by bearing arrangements 9 , respectively. The elastomer bearings 10 schematically shown in FIG. 1, which are connected to the support 4 of the roadway 3, respectively, by means of the outer slats 7. bearing structure 5 of the bridge. The exact design of the bearing arrangements 9 and 9, respectively. The elastomer bearing 10 is described in more detail in the following figures.

In many cases, as shown in FIG. 1, position the expansion joint 2 at an angle of 90 ° to the road 3. In the course of the slats 7, 8 obliquely to the longitudinal direction of the road 3 when the car passes the expansion joint 2, the bearing arrangement 9 exerts not only a vertical force but also a horizontal force. direction, respectively. In this case, the bearing arrangement 9 is intended to take over, in addition to the vertical load, also the load running in the longitudinal direction of the slats 7, 8. Such an inclined arrangement of the expansion joint 2, respectively. The intermediate and / or intermediate slats 8 are possible, as shown in FIG. 1, for curved or hill-shaped roads 11 and 11 respectively. from the tunnel 12, so that the location of the expansion joint 2 must be adapted to the natural environment.

In FIG. 2 and 3, an embodiment of the elastomer bearing 10, respectively, is described. bearing arrangement 9.

I

The elastomer bearing 10 consists of a bearing plate 13, a body 14 of the elastomer bearing 10 and a connecting plate 15. In the body 14 of the elastomer bearing 10, a plurality of elastomer layers 18 are located at least partially separated from each other by the reinforcement element 17. 19 is only between 1% and 20% perpendicular to the thickness 19 of the running width 20, preferably between 2 mm and 10 mm. The width 20 of the reinforcing elements 17 is smaller than the width 21 of the body 14 of the elastomer bearing 10 to completely surround the reinforcing elements 17 with the body 14 of the elastomeric

280 / B bearings 10, resp. The reinforcing elements 17 are the body 14 of the elastomer bearing 10 divided into a plurality of elastomer layers 18, the height 22 of the reinforcing elements 17 being less than the thickness 23 of the elastomer layers 18 of the body 14 of the elastomer bearing 10.

As material for the body 14 of the elastomer bearing 10, preferably elastomers, natural rubbers, elastomeric polychloroprene or ethylene-propylene terpolymers are used. Such terpolymers have good chemical resistance and have good weathering, ozone and aging resistance. The natural rubber is preferably used as the elastomer, since the natural rubber retains its good elastic properties even at low temperatures, which may occur under normal roadway loading loads. This advantageously achieves a very good load bearing under horizontal stresses. It is further advantageous that the Shore hardness of the elastomer, in particular the elastomeric layer 18 between the reinforcing elements, is between 50 Shore A and 90 Shore A, but preferably between 65 Shore A and 70 Shore A. forces.

By means of the material of the housing 14 of the elastomer bearing 10, a bearing plate 13 is possible on the housing 14 of the elastomer bearing 10 and the housing 14 respectively. the vulcanization or vulcanization of the connecting plate 15 to the body 14 of the elastomer bearing 10, whereby an advantageous fastening of the bearing plate 13, respectively, is achieved. of the connecting plate 15, since no further auxiliary means are required to secure them to the body 14 of the elastomer bearing 10. Further, by selecting the material for the body 14 of the elastomer bearing 10 or the width 21 of the body 14 and the thickness 23 of the elastomeric layers 18, it is achieved that the elastomeric layers 18 have a higher stiffness in the direction of the longitudinal axis than in the perpendicular direction.

As previously described briefly, the stiffening elements 17 are housed in the body 14 of the elastomer bearing 10, whereby the stiffness of the elastomer bearing 10 can be increased under load in the direction of the longitudinal centerline 24. These stiffening elements 17 can be formed from textiles, e.g. , knitted fabrics, netting, grill, web, or such fibrous or yarn materials of metal, ceramic, natural or artificial substances, or any mixture of these

280 / B materials. These reinforcing elements 17 have a width 20 by twice the dimension 25 less than the width 21 of the body 14 of the elastomer bearing 10, whereby the reinforcing elements 17 are completely surrounded by the material of the body 14 of the elastomer bearing 10. 17 is particularly advantageous, since the reinforcing elements 17 are thus prevented from contacting the ambient moisture, and thus corrosion damaging the reinforcing elements 17 can be prevented. Furthermore, the reinforcing elements 17 are positioned concentrically relative to the longitudinal centerline 24.

By making the elastomer bearing 10 or 10, respectively. of the elastomer bearing body 10 according to the invention, a surprising advantage is obtained that at high vertical loads occurring along the median longitudinal axis 24, only small deformation paths or only small spatial compression occur, so that small construction heights are sufficient. Furthermore, a sufficiently high elasticity is maintained transverse to the median longitudinal axis 24, thereby ensuring a sufficient load distribution in the plane of the slats. The transverse dimension of the body 14 of the elastomer bearing 10 is such that under a load transverse to the median longitudinal axis 24 and 24, respectively. with lateral deflection of the body 14 of the elastomer bearing 10, sufficient support of the intermediate and / or intermediate slats 8 is achieved with respect to the vertical loads occurring.

Of course, it is possible to form the elastomer bearing 10 or the body 14 of the elastomer bearing 10 in the load direction with each cross-sectional area, for example rectangular, square, circular, with a circular design, which gives the same deformation resistance in horizontal deformation .

The body 14 of the elastomer bearing 10 is connected on the faces parallel to the stiffening elements 17 to the body formed thereon, respectively. the abutment plate 13 formed thereon, respectively. the connecting plate 15, which consist of metal or plastic or a sandwich. On the front side 26 of the body 14 of the elastomer bearing 10 is mounted, preferably a vulcanized bearing plate 13. The bearing plate 13 has a bearing plate length 27 and a bearing plate width 28, with the bearing plate length 27 at least corresponding to

280 / B of the construction height of the elastomer bearing body 14 between the bearing plate 13 and the connecting plate 15 extending perpendicular to the reinforcing elements 17. Since the bearing plate 13 is formed overlapping the cross-section of the elastomer bearing body 14, the transition region between the elastomer bearing bearing 14 10 and the bearing plate 13 provided with a curvature 29, increasing the cross-section of the elastomer bearing body 14, which reduces the stress stresses in the transition region, thereby reducing the risk of loosening of the elastomer bearing body 14 by vibrational stresses occurring during operation.

On the end portion of the body 14 of the elastomer bearing 10 facing away from the bearing plate 13, respectively. the vulcanized connecting plate 15 such that the connecting plate 15 is completely embedded in the material of the body 14 of the elastomer bearing 10, that is, the bottom side 30 of the connecting plate 15 terminates flush with the face 31 of the body 14 of the elastomer bearing 10.

This abutment plate 13, respectively. the connecting plate 15 formed or formed on the face 26 or face 31, running parallel to the reinforcing element 17, consists of metal or plastic or a sandwich material. Furthermore, they are in the bearing plate 13, respectively. bores 32-36 in the connecting plate 15 to receive the fastening and / or adjusting means 37, in particular the bolts 38, these openings 32-36 may be made through and of course threaded 39.

The bores 32 to 36 in the bearing plate 13, respectively. In the connecting plate 15, which are directed parallel to the median longitudinal axis 24, there are preferably two, as this will secure the pivot against the elastomer bearing 10 and thus prevent the unwanted loosening of the screws 38 during operation due to vibration stress.

Screwing the seating plate 13 and / or the plugs into place. the coupling plate 15 is preferably provided with countersunk head screws 38, since in the horizontal vibration stresses arising from traffic due to the passage of cars and the braking effects of cars, less coefficient of friction is necessary due to less movements between the screw head and bores 32-36. thus increasing and improving contact. For other types of screws, u

280 / B of which the contact surface between the head of the screws 38 and the bores 32 to 36 in the connecting plate 15, respectively. In the bearing plate 13, located in the horizontal plane, such movements due to the necessary reduction of the friction coefficient can lead to an undesired loosening of the screw connection.

Furthermore, the dimensions of the mounting plate 13 and the mounting plate 13, respectively. The thickness 40 of the bearing plate 13 is designed such that, if the bearing plate 13 is subsequently welded with another component, sufficient heat dissipation is possible through the bearing plate 13 without damaging the material 14 of the elastomer bearing 10 by overheating.

In FIG. 4 to 6, the device 1 for bridging the expansion joint 2 is shown in detail.

As shown here, the outer slats 7 are formed as wall support profiles 41 and are fastened by means of anchoring elements 42, which are embedded in the parts 43 of the building or the building. in the supporting structure 5 of the bridge 6 and in the support 4. Between these wall supporting profiles 41 there is a centrally and / or interposed lamella 8, which is supported by an elastomer bearing 10, described in more detail in the previous figures, on the retaining structure 44 Such a support element 45 is formed as a component 46 with a U-shaped cross section gripping the connecting plate 15 of the elastomer bearing 10.

The member 46 is welded to the wall support profiles 41 on its side faces 47 facing the wall support profiles 41 to ensure a secure gripping of the component 46 on the wall support profile 41 and 41 respectively. securely supporting the central and / or intermediate lamella 8 by means of an elastomer bearing 10. This combination preferably provides an additional bearing arrangement 48 for the intermediate and / or intermediate lamellae 8 to bridge the expansion joint 2 between the supporting structure 5 and the bridge support 4 with at least one central and / or by an interposed lamella 8, which are supported by an elastomer bearing 10, respectively. This support is possible in that the central and / or intermediate plate 8 is connected in a fixed position by means of an elastomer bearing 10. This is achieved by the bearing plate 13 being mounted on the central and / or intermediate plate 8 and the coupling the plate 15 on the support element 45 by means of a fastening and / or adjusting 37 and / or an adjusting element. screws 38.

280 / B

As can be seen further from FIG. 4, the seating plate 13 and the connecting plate 15 are positioned concentrically relative to each other in the neutral rest position of the central and / or intermediate plate 8 and further align the longitudinal central axis 49 of the central and / or intermediate plate 8 with the central longitudinal axis 24 of the elastomer bearing

10. It is further evident that the surface 50 of the seating plate 13, respectively. the surface 51 of the connecting plate 15 are directed parallel to the running surface 52 of the central and / or intermediate lamella 8, respectively. the surfaces 50, 51 of the bearing plate 13, respectively. the connecting plates 15 of the elastomer bearing 10 are directed perpendicular to the longitudinal central axis of the central and / or intermediate lamella 8.

As previously mentioned briefly, the wall support profiles 41 on which the support members 45 are formed, preferably welded, are maintained in the building part 43 by means of further reinforcing elements 53 formed on these wall support profiles. 41 on parts of construction 43 using other fastening methods such as welding, screws and the like. Furthermore, the outer surface 54 of the wall support profile 41 abuts on the outer surface 55 of the building part 43, respectively. is embedded in these parts 43 of the building, thereby achieving an optimal support of the support element 45 welded to the wall of the wall support profile 41 facing the central and / or intermediate lamella 8.

Furthermore, the bearing arrangement 9 may be formed such that the central longitudinal axis 24 of the elastomer bearing 10 running in the main load direction 16 is directed parallel and in plan view is aligned with the longitudinal central axis 49 of the middle and / or intermediate plate 8 and by the bearing plate 13 is supported on another central and / or intermediate lamella 8, respectively. by the connecting plate 15 is supported on another central and / or intermediate lamella 8 or the support element 45 is supported on the wall support profile 41.

The arrangement of the retaining structure 44, respectively. of the elastomer bearing 10, and the parts which connect them to the adjacent parts 43 of the building, are designed so that there is sufficient space below the intermediate and intermediate lamellae 8 of the passageway of the roadway 3 and not required as in already existing systems 41. A particular advantage of this arrangement is that it creates the possibility of installing the entire passageway 3 up to the

280 / B by the definitive construction of the parts 43 of the building and the roadway 3 formed on the bridge 6 and the support 4. This makes it possible to adapt the running surface 52 of the central and / or intermediate slats 8 with respect to the inclination and height of the roadway 3.

In FIG. 5 shows a device 1 for bridging the expansion joint 2 in the roadway 3 in plan view.

As shown here, the retaining structures 44, which are formed of a support member 45 welded to the wall support profile 41 and the elastomer bearing 10, are alternately placed on one wall support profile 41 and spaced 56 on the other wall support profile 41 mirrored to the central longitudinal. In order to allow a uniform load distribution across the center and / or intermediate slats 8 or elastomer bearings 10, it is necessary that at least two or more retaining structures 44 are located between the building parts 43, thereby also ensuring a uniform distribution. The distance 56 between the retaining structures 44 measured in the longitudinal direction of the central and / or intermediate slats 8 also corresponds to a support distance 58, this support distance 58 between the two elastomer bearings 10 supporting the central and / or intermediate slats 8. it must be smaller than the period of the excitation pulse frequency acting on the center and / or intermediate slats 8, or it is less than twice the period of the excitation pulse frequency acting on the center and / or the intermediate slats 8.

By this arrangement of the elastomer bearing 10 and in that the two elastomer bearings 10 forming a single pair are connected to the middle and / or intermediate slats 8 and 8, respectively. By means of wall support profiles 41, these elastomer bearings 10 are alternately compressive in the direction of movement against the longitudinal direction of the slats. The elastomer bearings 10 are located below the intermediate and intermediate plate 8 and are connected to the intermediate and intermediate plate 8 by means of a bearing plate 13 and the connecting plate 15 of the elastomer bearing 10 is supported by a support element 45 on the wall support profile 41.

280 / B

Large distance 56, respectively. the large support distance 58 can induce intrinsic oscillation frequencies that are superimposed on the excitation pulse frequency, so that upon further stressing of the retaining structure 44, respectively. The elastomer bearings 10 may be subject to fatigue fracture. Therefore, the support distance between the two elastomer bearings 10 is less than 2 m, but preferably between 0.7 and 1.3 m.

Another advantage of the further bearing arrangement 48 is the possibility of additional placement in the bridging device 1. As a result, the fatigue fracture of the retaining structure 44 can be reliably avoided in existing bridging devices 1. If the elastomer bearings 10 have a large support distance 58, the middle and / or intermediate plates 8 can be vibrated under load, which can lead to dangerous approaching the frequency of natural oscillations and the frequency of excitation pulses when the vibration damping effect is not achieved. This additional placement of the elastomer bearings 10 can be carried out independently of the type of construction of the bridging device already used so that it can occur at any time without damaging the adjacent parts 43 of the building and without limiting traffic.

FIG. 6 shows a better retaining structure 44 and 44, respectively. support member 45 for elastomer bearings 10. Here, the support member 45 is formed by a metal part with a U-shaped cross section which is fastened, preferably welded, to the wall support profile 41. The elastomer bearing 10 is in the region 59 of the support member 45 formed in the support member. The U-shaped cross-section connected to the base 60 of the support element 45. This connection can be made by all possible fastening methods suitable for this case, preferably screws 38 are used as fastening and / or adjusting means 37.

The fastening is achieved by inserting fastening and / or fastening means 37 which are screwed into the bores 61 in the support element 45, which are flush with the bores 34, through the bores 34, 36 in the connecting plate 15 vulcanized on the body 14 of the elastomer bearing 10. 36 of the connecting plate 15. This screwing occurs in the longitudinal direction of the slats 8 by means of two fastening and / or adjusting means 37 spaced apart in order to

280 / B prevented undesirable loosening of the elastomer bearing 10 under vibration stresses occurring during normal operation.

The mounting of the seating plate 13 vulcanized on the body 14 of the elastomer bearing 10 occurs in a similar way, with the fastening and / or adjusting means 37 being pushed through the bores 32, 33 in the seating plate 13 and screwed into the holding holes 62 in the middle post 63 of the middle and / or intermediate slats. These clamping holes 62 are preferably formed by blind holes

64. By positioning the clamping holes 62 on the central and / or intermediate lamella 8 in the region of the central upright 63, the notch effect in the lower region of the central and / or intermediate lamella 8 is reduced, particularly on its upright.

The fastening of the elastomer bearing 10 to the central and / or intermediate lamella 8 is designed such that the clamping holes 62 for the fastening and / or adjusting means 37 are located in the cross-sectional area of the underside of the central and / or intermediate lamella 8 facing the elastomeric bearing 10 intersecting. This achieves that the elastomer bearings 10 are connected by means of both fastening and / or adjusting means 37, passing through the bearing plate 13, in the region of the middle post 63 or in the region of the underside of the middle post 63 to the middle and / or or an intermediate plate 8.

In FIG. 7 to 12 show a device 1 for bridging the expansion joint 2 in the roadway 3 behind two intermediate slats 65 and one central slat 66, which are located between the two wall bearing profiles 41. Furthermore, bearing arrangements 9 associated with the intermediate slats 65 and middle slat 66 are shown. .

The two bearing arrangements 9 are again located at a support distance 58 according to the invention which is smaller than 2 m and preferably between 0.7 m and 1.3 m, whereby a bearing arrangement 9 is provided for supporting or bearing the load of the two intermediate plates 65 and another bearing arrangement 9 for supporting or bearing the load of the central lamella 66. The bearing arrangement 9 for the intermediate slats 65 is designed as a bearing arrangement 9 shown in FIG. 6 and with reference to embodiments thereof, reference is made to the parts of the description relating to FIG.

280 / B

A further bearing arrangement 9 for the intermediate slats 65 is formed as shown below. On the undersides of the intermediate slats 65, the gripping profiles 67 are fixedly connected, preferably welded, to the undersides of the intermediate slats 65, the longitudinal axis of the gripping profile 67 aligned with the central axis 68 that extends in the longitudinal direction of the intermediate slat 65. The cross-member 69 is supported by a transverse beam 69 supported by an elastomer bearing 10 on the retaining profile 67, which extends perpendicular to the axis 57 of the spacer joint 2 and is supported on another interposed lamella 65 equally over the elastomer bearing 10 on the retaining profile 67. 58 between two elastomer bearings 10 according to the invention is less than 2 m, but is preferably between 0.7 m and 1.3 m.

In the region of the center lamella 66, the crossbeam 69 is immovably connected, preferably welded, to the center lamella 66, through the contact surface 70, thereby allowing the vertical load of the center lamella 66 to be exerted through the elastomer bearing 10 positioned in the retaining profile 67.

To achieve a uniform load distribution perpendicular to the spacer gap basket 57, it is advantageous to place two different bearing arrangements, or multiple of two different bearing arrangements 9, along the intermediate slats 65 or the center plate 66. This location of the bearing arrangements 9 also changes the dilatation gap 71 permits the parallel lamellas 65 or the central lamella 66 to be parallel to one another.

In FIG. 8 and 9, there is shown the support of the intermediate slats 65 by means of a support element 45 on the wall support profile 41.

It is stated that the support 4 is formed as a fixed part 43 of the building and the supporting structure 5 of the bridge 6 as a supporting part 43 of the building, which can be adjusted by temperature fluctuations according to the double arrow 72. they are positioned such that the longitudinal center axes 24 of the elastomer bearings 10 and the longitudinal center axes 49 of the intermediate plates 65 or the intermediate plates 66 extend parallel to each other or are aligned.

280 / B

In this position of the bridging device 1, or of the slats 65 or of the central slat 66, respectively, is the load bearing of the elastomer bearings 10 reinforced by the reinforcing elements 17, at most in the direction of the main load 16. This occurs when, in this position of the elastomer bearings 10, the width 21 of the body 14 of the elastomer bearing 10 is as large as the width 73 of the bearing surface 74 extending perpendicular to the median longitudinal axis 24 of the elastomer bearing 10.

This is achieved in that the cross-section of the bearing surface 74 in this position corresponds to the cross-section of the body 14 of the elastomer bearing 10 and can transmit as much stress as possible in the main load direction 16. In this position, the expansion joint 2 has a spacing 71, and by uniformly distributing the load of the bearing arrangements 9, the central slat 66 or the intermediate slats 65 have the same large slat distance 75 continuously.

In order to illustrate the deformation behavior of the elastomer bearing 10 according to the invention as well as the displacement of the slats 8, 66, 65 under load, FIG. 8 schematically explains the deformation and displacement of the individual plates 8, 66, 65 under load.

The intermediate slats 65 and the center slat 66 are located at a temperature corresponding to the calculated base temperature at a calculated slat distance of 75.

This lamella distance 75 is measured such that the maximum plasticity of the elastomer bearing 10 perpendicular to its longitudinal direction, i. in the radial direction, it is sufficient to compensate for the differences in elongation of the support structure 5 with respect to the support 4 between the maximum maximum temperature and the maximum minimum temperature. That is, the sum of the lamellar distances 75 must be so large that at the maximum elongation of the supporting structure 5, provided that the same bearing arrangements 9 are located at both ends of the supporting structure 5, they must be at least equal to or greater than half the maximum overall length change. supporting structure 5.

This also applies to the reduction of the overall length of the supporting structure 5 at extremely low temperatures, whereby it is usually taken into account that the position shown in FIG. 8, wherein in FIG. 9 shows the position of the individual slats at higher temperatures than 65.66

280 / B average temperature, that is to say with the increased length of the supporting structure 5. If the supporting structure 5 of the bridge 6 is shorter due to lower temperatures below the average annual value, the elastomer bearings 10 deform into the mirror position shown in FIG. 9 with respect to the longitudinal centerline 49 of the center plate 66.

I

When, for example, an automobile 102 passes through the bearing arrangement 9, the bearing arrangement 9 or its elastomer bearing 10, in addition to possible deflections by changing the lamella distance 75, assume and simultaneously dampen the loads arising in the main load direction 16, so. the cyclic stresses acting on the support 4 or the supporting structure 5 are preferably low.

For the sake of clarity, only one wheel is shown in the illustrated form

102, the diameter of which is selected to abut only one of the intermediate plates 65 and the intermediate plates 66. The elastomer bearing 10 is loaded by the vertical load transmitted through the wheel 102 and is compressed in the longitudinal direction of the longitudinal center axis 49 and therefore of the adjacent central lamella 66 and the wall support profile 41.

Here, the load acts as a load wave, since the wheel 102 starts to rest slowly when approaching the wall support profile 41, so that the continuously increasing portion of the vertical load is transmitted by the insert plate 65 and the load on the wall support is correspondingly reduced. If the entire vertical load is transmitted by the intermediate lamella 65 and the wheel 102 moves further in the direction of the central lamella 66, it will then occur that the wheel 102 will partially rest on the middle lamella 66 so that the elastomer bearing 10 supporting this middle lamella 66, increasingly compresses under increasing load until the same height on both the intermediate plate 66 and the intermediate plate 65 reaches the same height of the two plates 65, 66 or an equally large drop

103. When the main load is constantly increasing on the central slat 66, the central slat 66 further decreases and, in contrast, the first loaded intermediate slat 65 rises to its rest position shown in solid line.

280 / B

When the load is further shifted, resp. when the wheel 102 is further rotated, the same load exchange occurs between the intermediate plate 66 and the next intermediate plate 65 in the direction of the support 4.

At the same time, the cushioning effect between the support structure 5 and the support 4 can be achieved by radial deformation of the elastomer bearing 10, so that the oscillation of the support structure 5 cannot continue to the support 4. Such oscillations can be generated by traffic loads passing through cars or the like. 10th

It will be appreciated that the introduction of vertical forces occurs only in a narrow partial region along the length of the slats 8, 66, 65. This means that the vertical load currently introduced in the narrow region of the slats 8, 66, 65 continues in the longitudinal direction of the slats. , 66, 65 over other elastomer bearings 10 as oscillations. Since the occurrence of oscillations is caused by main loads, such as pressures of high speed cars or pressures due to the track and wheelbase, and thus the resulting oscillation is generally known, it is necessary to ensure that the distance between the individual elastomer bearings 10 in the longitudinal direction of the slats 8 , 66, 65 was determined such that resonant oscillations do not occur at commonly occurring vibration ratios of the slats 8, 66, 65.

Resonance oscillations are avoided by firstly forming the elastomer bearing 10 according to the invention by means of reinforcing elements 17 and, secondly, by a supporting distance 58, i.e. the distance between the elastomer bearings 10 assigned to the same slats 8,66,65 and supported by other identical slats 8, 66, 65. The carrier profile 41 is such that the distance is, for example, less than the frequency of the oscillations, as explained above.

In FIG. 9 shows the position of the elastomer bearing 10 and the slats 8, 66, 65 at a reduced pitch 71 caused by temperature fluctuations.

If the bridge 6 is widened due to the temperature increase in the longitudinal direction, the spacing of the spacing 71 or the wall support profile 41 fixed to the support structure 5 is approached, the wall support profile 41 located on the support 4. By pressing the bridging device 1. the interposed slats 65 respectively. the central lamella 66 is evenly closer to each other, again allowing the same

280 / B a large flange distance 75. This uniform reduction of the flange distance 75 is made possible by the design or the placement of the elastomer bearing 10, respectively. The intermediate lamella 66 is supported over the crossbeam 69, as further described in the following figures, through the elastomer bearing 10 and the gripping profiles 67 on the intermediate lamellae 65.

By reducing the pitch 71, the elastomer bearings 10 also deform in a horizontal direction, so that the median longitudinal axis 24 extends at an angle 76 from the direction of the wall support profiles 41 and the animal with the longitudinal median axis 49 of the intermediate slats 65. the distance 71 of the expansion joint 2, the greater the angle 76 between the median longitudinal axis 24 of the elastomer bearing 10 and the median longitudinal axis 49 of the intermediate slats 65. This arrangement of the elastomer bearing 10 is possible with the embodiment a high load bearing in the main load direction 16, but has a sufficiently high elasticity in the horizontal direction to allow such deformations to be assumed without fracture.

Deflection, respectively. the inclined position of the elastomer bearing 10 under horizontal stress, seen in the vertical direction, causes a reduction in the width of the bearing surface 74. It follows that the width 21 of the body 14, i. The elastomeric layers 18 and reinforcing elements 17 must be greater than the width 21 of the body 14 of the elastomer bearing 10, calculated from the bearing surface 74 needed to assume the maximum bearing load 10 by a maximum adjustable level between the bearing and / or connecting plates 13, 15. Furthermore, the overlapped area between the end faces of the body 14 of the elastomer bearing 10 facing the bearing plates 13 and the connecting plates 15 must overlap when the bearing and / or connecting plates 13, 15, seen in a direction parallel to the median longitudinal axis 24, an overlapping surface or abutment surface 74 which corresponds to the transverse surface of the body 14 of the elastomer bearing 10 for the ultimate limit in the direction 16 of the main load.

280 / B

Furthermore, the structural heights of the elastomer bearing 10 must be kept as small as possible to prevent the deflection of the elastomer bearing 10 and the high vertical load of the buckling body 14 of the elastomer bearing 10 provided with reinforcing elements 17. In this geometrical condition. 74 yields the highest possible load occurring in direction 16 of the main load.

FIG. 10 and 11, a bearing arrangement 9 for a center plate 66 is described.

The crossbeam 69 for supporting the central slat 66 has a triangular cross-sectional side view, with a pedestal 77 formed on both sides in the end regions facing away from the central slat 66, so that the cross-beam 69 corresponds in a cross-sectional front view of the letter T standing on the head. In the region of the centered lamella 66, the crossbeam 6 forms a contact surface 70 by means of which it is rigidly connected, in particular welded, to the underside 78 of the central lamella 66. Thus, the middle lamella 66 is fastened to the crossbeam 69 by force and fit. two mutually adjacent intermediate slats 65 over other elastomer bearings 10 in the gripping profiles 67 connected to the intermediate slats

65th

In both end regions of the crossbeam 69 facing away from the longitudinal centerline 49 of the central lamella 66, the uprights 77 have apertures 79 that align with the bores 32, 33 of the seating plate 13 of the elastomer bearing 10, and the crossbeam 69 can be rigidly connected to the This fastening can preferably be made by screwing, since it constitutes a firm but if necessary detachable connection.

The connecting plates 15 of the elastomer bearing 10 are rigidly connected by means of fastening and / or adjusting means 37 to the gripping profile 67, the same fastening of the elastomeric bearing 10 to the gripping profile 67 being shown in more detail in the following figure. 12th

280 / B

As a result, the elastomer bearing 10 is connected to the intermediate plate 65 via an anchoring profile 67 by means of the two fastening means 80 passing through the bearing plate 13 in the region of the cross member 77 of the transverse beam 69. Further, the elastomer bearings 10 are opposite sides of the immediately adjacent intermediate lamellae 65 disposed in a plane extending perpendicular to the longitudinal centerline 49.

If the spacing 71 is also reduced here, the lamella distance 75 is reduced equally and the horizontal stresses on the bearing arrangement 9 cause the deflection of the elastomer bearings 10 or the bodies 14 of the elastomer bearings 10. By this embodiment of the bearing arrangement 9, not only the vertical load 1 for bridging conditionally driven by cars, but at the same time a uniform distribution of the central lamella 66 or intermediate lamellae 65 in the expansion joint 2 is also provided for bridging the gap. Furthermore, it is also possible to maintain uniform lamellar distances 75 between the individual central lamellae 66 slats 65 at different elongation states of the building section 43.

It is further disclosed that by dimensioning the elastomer bearing 10, the elasticity can be easily adjusted to the loads occurring in different spatial directions, yet the elastomer bearings 10 ensure a high load bearing, so that even at higher loads it can suffice to support the center plate 66 or . The plasticity of the elastomer bearing 10 is less in the main load direction 16 than in the direction transverse to the main load direction 16, and due to the smaller thickness 19 of the reinforcement elements 17, a greater number of them can be placed and yet a sufficiently transverse displaceability or transverse plasticity of the elastomer bearing 10 can be achieved due to the exact positioning of the individual slats 65, 66.

In FIG. 12, there is shown an abutment device 81 formed by a gripping profile 67 for receiving a transverse beam 69 carrying a central lamella 66 with an inserted reinforced elastomer bearing 10.

280 / B

The gripping profile 67 formed of metal is U-shaped, the arms 82 of the gripping profile 67, respectively. its front faces 83 are rigidly connected, preferably welded, to the underside 78 of the interposed lamella 65. Both arms 82 are connected transversely to a running base 84 therebetween. Corner regions 85 of the gripping profile 67 are formed between the base 84 and arms 82 and are rounded a radius 86 to prevent fracture notch effects in these areas.

The base 84 further has holes 87, 88 corresponding to the bores 34, 36 of the connecting plate 15, by means of which the elastomer bearing 10 and 10 can be fastened. the connecting plate 15 of the elastomer bearing 10 by means of fastening and / or adjusting means 37 on the base 84 of the gripping profile 67. The elastomer bearing 10 comprises only schematically illustrated reinforcing elements 17 disposed in the housing 14 of the elastomer bearing 10 in the direction of the faces 83 to the seating plate 13, which is in alignment with the cross member 69 of the crossbeam 69. This cross member 77 is rigidly connected by holes 89, 90 formed in the web 77 corresponding to the bores 32, 33 of the bearing plate 13 by means of fastening means 80. as this will provide a secure connection which can also be released if necessary. Further, the crossbeam 69 has a further upright 91, which is located in the direction of the central lamella 66 and which is rigidly connected, as briefly described above, by the contact surface 70 to the central lamella 66.

Surprisingly, this embodiment of the gripping profile 67 according to the invention achieves the advantage that the gripping profile 67 is designed to secure against the fracture of the elastomer bearing 10. If the material failure of the body 14 of the elastomeric bearing 10 or external weathering leads to the fracture of the elastomeric bearing 10 67 is designed as a type of retaining cage, thereby engaging the underside 92 of the crossbeam 69, respectively. This embodiment according to the invention of this bearing arrangement 9 makes it possible to operate the bridging device 1 up to the necessary maintenance and repair work.

In FIG. 13 and 14 show another variant of the embodiment of the bridging device 1 in plan view, respectively. in side view.

280 / B

Here, the elastomer bearings 10 are made horizontal, that is, the median longitudinal axis 24 of the elastomer bearings 10 extends parallel to the median axis 68 of the middle lamella or intermediate slats 65. The elastomer bearings 10 are located below the middle lamella 66 or intermediate slats 65 and fastening and / or adjusting means 37, in particular screws 38, connected to the support body 94.

On the first side surface 95 of the support body 94, the abutment plate 13 of the elastomer bearing 10 is fastened by means of fastening and / or adjusting means 37, preferably screws 38, on the second side surface 96 of the support body 94 opposite to the first side surface 95. By means of this support arm 97, a second elastomer bearing 10 is provided which is transverse to the central axes 68. The support arm 97 is preferably made of a highly durable material, for example metal. Furthermore, an end support arm 98 is provided on the connecting plate 15 of the elastomer bearing 10, which is also connected thereto by means of fastening and / or adjusting means 37, preferably screws 38. This end support arm 98 is located away from the connecting plate 15 of the elastomer bearing 10 and is rigidly connected thereto, in particular welded. By firmly connecting the end support arm 98 to the wall support profile 41, it is possible to sufficiently support this bearing arrangement 9 in the longitudinal direction of the roadway 3.

In the end region facing away from the support body 94, the support arm 97 is connected, again by means of fastening and / or adjusting means 37, to the connecting plate 15 of the following elastomer bearing 10, optionally located on the middle plate 66.

An embodiment of the bearing arrangement 9, which is located on the next wall support profile 41, is obtained by mirroring the first bearing

280 / B of arrangement 9 about the central axis 68 of the central lamella 66 and the transverse axis which is located in the longitudinal direction of the roadway 3.

This particular positioning of the elastomer bearings 10 in the lying position makes it possible to carry horizontal loads instead of vertical loads in the longitudinal direction of the slats 65, 66. This makes it possible to place the bearing arrangement 9 only with vertically oriented elastomer bearings 10 or only horizontally aligned Of course, it is also possible to use combinations of different bearing arrangements 9, which depends on the types of load.

If the transitions of the roadway 3 are inclined, respectively. they are oriented obliquely to the longitudinal direction of the road 3, thus the driving direction and the direction of the steering forces are not perpendicular to the slats 8, 65, 66, a horizontal component acting in the longitudinal direction of the slats 8, 65, 66 is formed during rolling and braking. the bearing 10 to prevent undesirable horizontal movements of the slats 8> 65, 66 towards the middle slat 66, respectively. of the intermediate lamella 65, lying flat in one place. The positioning of the elastomer bearing 10 is carried out in such a way that the direction of its movement coincides with the direction of movement of the central lamella 66, respectively. of the interposed lamella 65 and the vertical loads lead to shear deformation.

Furthermore, the bridging device 1 is formed in such a way that the elastomer bearings 10 are located below the central lamella 66 and are connected by means of a bearing plate 13 or a connecting plate 15 to the interposed lamellas 65 and a further bearing plate 13 of the elastomer The bearing is supported by the support arm 97, respectively. The support leg 98 is supported on an adjacent intermediate lamella 65 or on the wall support profile 41. Further, the elastomer bearings 10 of one centrally positioned central lamella 66 are connected via the intermediate lamella 65 disposed therebetween and the wall support profile 41, the wall support profile 41 and others. the elastomer bearing 10 is connected to, or supported on, another wall support profile 41 via an interposed lamella 65 disposed therebetween and another wall support profile 41. Also, the elastomer bearings 10 are disposed between the intermediate plate 66 and the intermediate plate 65 or various intermediate plates 65.

280 / B or an intermediate lamella 65 and a wall support profile 41 in the direction of the central axis 68 of the lamellae 65, 66 side by side. Further, the distance 100 between the central axes 68 of the intermediate lamina 66 and the intermediate lamina 65 is as large as the distance 101 between the median longitudinal axis 24 of the elastomer bearing 10 associated with the intermediate lamina 66 and the median longitudinal axis 24 of the elastomer bearing 10 associated with the intermediate lamella 65.

In FIG. 15 shows another embodiment of the bearing arrangements 9 for the center plate 66 and the two intermediate plates 65 located at the center plate.

This is the view of FIG. 10, wherein the central lamella 66 is not supported by the crossbeam 69 on the intermediate slats 65. It will further be appreciated that the support of the intermediate slats 65 adjacent to the wall support profiles 41 is made as shown in FIG. 8th

In this embodiment, the center plate 66 is also connected to the elastomer bearing 10 on its underside 78 by means of fastening and / or adjusting means 37. The elastomer bearings 10, fixed to the center plate 66, are again connected by their connecting plate 15 to the base 60 of the support element. 45 by means of fastening and / or adjusting means 37.

The support element 45 is formed in the same way, respectively. similar to that of FIG. 4, which is a U-shaped cross-section, preferably of metal. In order to avoid unnecessary repetition, reference is made to the detailed description of FIG. 6th

In this embodiment variant, the support elements 45 are immovably fastened, preferably welded, with the U-shaped front edges 104 welded to the intermediate slats 65 to their undersides 78. The intermediate slats 65 are again supported by elastomer bearings 10 which are fastened to the supporting elements. These support elements 45, facing the intermediate slats 65, are again fastened, preferably welded, to the wall support profile 41 embedded in the support 4 or in the support structure 5, as best seen in FIG. 8th

280 / B

The advantage with respect to the bearing arrangements 9 shown in FIG. 8, it follows that each lamella 65, 66 is associated with elastomer bearings 10, thereby allowing a greater spacing 71 of the expansion joint 2 in the longitudinal direction of the road 3 compared to the aforementioned variants. This advantageous embodiment of the bridging device 7 also achieves a uniform distribution of the slats 65, 66 in the longitudinal direction of the road 3 at higher pitches 71, thereby also ensuring constant slat distances 75 between the individual slats 65, 66.

By using the support members 45 to support the center lamella 66 on the intermediate slats 65, which are constructed in the same way as the support members 45 which support the intermediate slats 65 on the wall support profiles 41, the number of components for mounting the bridging device 1 is reduced. an embodiment of the bridging device 1.
