Definitions
- the invention relates to a bridging device for expansion joints in bridges or the like extending transversely to the transport route longitudinal slats which g on both sides in the foot enr capablen rotatably and slidably supported, the gap obliquely to the transport route longitudinal axis bridging crossbeams via antifriction bearing parts are mounted pivotably, wherein the cross member through openings are inserted in or on the underside of the lamellae and the bearing parts are designed as non-rotatable and elastically flexible sliding pivot bearings, each of which has at least one bearing body, so as to be rotationally fixed to the cross members and slidably connected to the lamellae relative to the latter.
- Such a bridging device is already known from DE-PS 27 46 490.
- the bearing bodies are essentially designed as circular disks, each having a groove for slidably receiving the crossbeams.
- Projections of the La GerkMech serve as guides for the sliding movements of the cross member. At the same time, they serve to transfer horizontal forces from the lamella to the cross member.
- the projections encompassing the crossbeams have the shape of circular sections due to the circular shape of the bearing bodies, with only a small area being available for transmitting the transverse forces to the crossbeams, since a considerable wall thickness is required for such projections in order to transmit force effectively, as is only possible in given the central portion of the protrusions.
- the projections of the bearing bodies are exposed to very large loads as a result of the transmission of transverse forces, which can lead to damage to the bearing bodies soon after only a short period of use.
- Braking or acceleration forces as well as the eccentric attack of the vertical wheel load on the lamella generate a tipping moment that tries to cause the lamella to lift off the bearings arranged on the cross members under a considerable Apply vertical pretension to the cross member.
- This large preload in turn results in a high level of friction between the bearing bodies and the cross members, so that to avoid overloading the lamella.
- Braking forces desirable slipping clutch effect between the bearing bodies and the cross members is triggered only at very high braking forces. If the preload is reduced in the course of time by relaxation of the bearing bodies, there is a risk that the fins suddenly lift off from the bearing bodies when a tilting moment is introduced. This leads to the destruction of these bearing bodies after a relatively short time.
- the object of the invention is to improve a bridging device of the type mentioned in such a way that the force and torque transmission from the slats to the crossmember takes place easily and independently of the prestress acting in the bearing body, so that the bearing bodies have a longer service life and the Height of the preload of the bearing body can only be selected from the point of view of the setting of the slip clutch between the plate and the cross member.
- this object is achieved in that the bearing body is essentially cuboid and is guided in a groove of the cross member.
- each slide pivot bearing expediently has one bearing body arranged above and one below the crossbeam Can lift the load by moving it on the crossbeams against the friction forces dependent on the vertical preload of the bearing body.
- the bearing body advantageously consists of an elastomer and is provided on its sliding surface and on the opposite surface with a plate made of abrasion-resistant, low-friction material.
- This plate is expediently a steel plate which is provided with a sliding layer.
- the plate proof of the surface of the bearing body opposite the sliding surface has a circular blind hole into which a circular disk-shaped guide pin engages, which is attached to a plate welded to the lamella.
- the La g per erkör- have a length such that in each case a gap remains between the slats in their compressed state, while the bearing bodies of each transverse beam adjacent to each other with their end faces. This ensures that there is no noise when driving over the slats created by touching slats.
- the minimum distance remaining between the slats is: expediently 5 mm wide.
- All cross members are expediently connected to all the slats by means of sliding pivot bearings.
- crossmembers are advantageously limited in their displacement by means of stops arranged in the joint edges so that they cannot slide out of the joint edges.
- further sliding pivot bearings can be provided to support the ends of the cross members.
- At least three cross members are arranged obliquely alternately with respect to the slats and to one another.
- FIG. 1 shows one of the cross members 1, which runs obliquely to the plane of the drawing, with two slats 2 and 3 supported thereon.
- An edge lamella 5 or 6 is connected to each joint edge body 4.
- the two ends of the cross member 1 each protrude into a cavity 7 of the associated joint edge body 4.
- the slats 2 and 3 can have openings through which the cross members 1 are inserted or have a U-frame 18 on their underside which circumscribes an opening 9.
- the slats 2 and 3 are supported on the cross beams 1 via sliding pivot bearings, each of which consists of an upper bearing body 10 and a lower bearing body 11.
- the bearing bodies 10 and 11 are essentially cuboid. At the ends of the cross member stops 11 a, which limit the displacement of the cross member in both directions, are provided.
- FIGS. 2 and 3 show the precise design of the bearing bodies 10 and 11. 2 and 3 is accommodated in the U frame 18 arranged on the underside of a lamella 17. Its legs are attached to the underside of the lamella 17 by welding. A plate 16 with a guide pin 19 is welded to the underside of the lamella 17. The guide pin 19 engages in a circular blind hole 20 of a steel plate 21, with which the bearing body 10 is provided on the surface 23 opposite the sliding surface 22.
- the lower bearing body 11 is fastened in a corresponding manner to the U frame 18, a plate 16 provided with a guide pin 19 being welded to the C frame.
- the guide pin 19 in turn engages in the circular blind hole 20 of the steel plate 21.
- the bearing bodies 10 and 11 are arranged in a groove 24, which is formed in the top and bottom of the cross member 1, in which the bearing bodies are guided by the side walls 25.
- the side walls 25 also serve to transmit horizontal forces from the lamella 17 to the cross member 1.
- Figures 3 and 4 show the bridging device with minimal joint opening.
- the bearing bodies 10 and 11 of the respective cross members 1 abut one another with their end faces 26.
- a minimal gap 27 remains between the lamellae, which has a size of approximately 5 mm. This design reliably prevents the slats from touching one another under the action of horizontal forces and thereby generating undesirable noises.
- FIGS. 5 to 7 each show the top view of a bridging device, only cross members and slats being shown schematically.
- the total of four slats 1 are supported on a total of four cross members Q and q.
- the cross members are mutually aligned and inclined to the slats, ie two cross members Q are to the right and two cross members q are inclined to the left.
- Each cross member is connected to each lamella by means of a slide bearing G according to FIGS. 1 to 3. Since the pivot points of the plain bearings are fixed with respect to the lamellae, a change in the joint width inevitably results in a pivoting and shifting of the cross members Q with respect to the lamellae 1, which are always parallel to one another.
- FIG. 7 shows the maximum open joint, which has a width of approximately 80 mm, the distances between the lamellas increasing and the angle formed between two adjacent cross members decreasing at the same time.
- FIG. 5 shows the smallest possible joint, the bearing bodies abutting one another.
- the angle enclosed between adjacent cross members Q and q increases compared to the central position shown in FIG. 6.
- the slats must be uniformly adjusted to one another regardless of the respective joint width.
- the gap between the slats and the gap between the edge slats and the joint edges are the same size for each joint width according to the play of each slat control.
