Description

The present invention relates to a bridging device for bridging a joint gap between a fixed bridge component and a movable bridge component of a movable bridge.

A movable bridge is to be understood here as meaning a bridge whose supporting structure can be moved as a whole or in parts. Movable bridges are typically used to temporarily increase or even release a clearance under the moving part of the bridge. In order to increase or release the clearance, the movable bridge component is at least partially separated from the fixed bridge component and lifted depending on the type of bridge (lifting bridge), folded up (bascule bridge) or twisted in a horizontal plane (swing bridge). In addition to the bridges mentioned here, there are a variety of other movable bridges, to which this invention also relates.

When closed, a joint gap is created between the movable bridge component and the fixed bridge component. This should have a defined size to compensate for relative movements between the building parts and so avoid contact and thus tensile, compressive or torsional stresses between the adjacent building parts. The size of the joint gap is therefore chosen in the construction of the bridge so that the building parts as possible during their use do not touch. The joint gap can therefore have relatively large dimensions and vary greatly depending on the load on the bridge.

For fixed bridges, the joint gap is bridged by means of a bridging device. This ensures that even large joint gaps can be safely crossed by the users of the bridge, so that people do not fall into the joint gap or wheels of vehicles do not lower into the gap. In this respect, such a bridging device ensures the most continuous possible transition between the building parts. This also means that as quiet as possible driving over with vehicles is possible bridging devices for fixed bridges are in the EP 355 009 A2 and EP 0 821 104 A2 described.

In contrast, the joint gap is usually left open in known movable bridges usually, so no bridging device arranged in or over the joint gap. The reason for this is that moving bridges rarely occur, sometimes have smaller dimensions and are often run over at low speeds. Therefore, the joint gap size is usually low anyway and the noise pollution is lower due to the lower speed.

As an alternative to leaving the joint gap open, bridging devices designed as so-called finger joints are sometimes used. These have two finger plates arranged in a combing arrangement. In this case, a finger plate on the fixed structure part and the other is fixed to the movable component. The latter is thus moved with the movable bridge component. When closing the bridge, the fingers mesh with each other in such a way that the joint gap is partially bridged.

Both when leaving open the joint gap, as well as when using finger joints, the maximum bridgeable gap size is limited, so that vehicles do not sink too much in the joint or because the fingers of the finger plates can not run indefinitely

A known transition device for a movable bridge, wherein the bridge is equipped with a positioner device is in the US 625,097 described.

Against this background, it is an object of the present invention to provide a bridging device, which makes it possible to bridge both smaller and larger joint gaps in movable bridges can.

The solution of the problem is achieved with a device according to claim 1 and a movable bridge according to claim 22. Advantageous development of the invention are described in the subclaims.

The bridging device according to the invention is therefore distinguished from the prior art in that it comprises a transition structure with at least one movable support and at least one positioning device for selectively positioning the at least one movable support of the transition structure after moving the movable bridge member in the joint gap between the fixed and the having movable bridge part.

In this case, the transitional construction is to be understood as the part of the bridging device which ultimately compensates for the relative movement between the structural parts, with the bridge closed. By contrast, the bridging device designates the entire unit, with components on the fixed as well as on the movable bridge component.

In this case, the movable support of the transitional construction is to be understood as any type of support which can be moved relative to the transitional structure. The movable support may be part of the transition structure. But it can also be arranged in addition to the transition structure. The movable support can also consist of a variety of components.

In order to bring the movable support in the desired position when closing the bridge, the lock-up device has a positioning device. In this case, the positioning device is to be understood as meaning any type of device which enables a specific positioning of the movable carrier. This can be done, for example mechanically, but also hydraulically, or electrically.

Generally speaking, the approach is based on the idea of using complex transitional constructions, such as swiveling-transition constructions, also on movable bridges. Such complex transitional structures then make it possible to bridge joint gaps caused by large expansions and / or tilts. Even with transverse strains / displacements solution of the invention has significant advantages over a finger joint. Thus, the solution is also very well suited for large or wide bridges.

Conveniently, the positioning device on a pin. Under a pin is to understand any kind of bolt or projection, which can target mechanically targeted by its shape and physical contact with another bridge component positioning.

Furthermore, it is advantageous that the positioning device has at least one guide for the pin, which is preferably funnel-shaped. Such a mechanical design of the positioning is inexpensive to manufacture and resistant to failure and contamination. Preferably, a horizontal force is generated by an engagement of the pin in the guide, which ultimately ensures the positioning. The pin and the guide can have any shapes and should not be limited to funnel-shaped or round designs. However, the funnel-shaped design of the guide has the advantage that positioning in both the transverse and in the longitudinal direction can be done in a simple manner.

Conveniently, the pin and / or the guide at least one friction-reducing bearing element, preferably a sliding plate of a sliding material and / or a roller. Under bearing element is to be understood as any device that reduces the friction between pin and guide. Slide plates have the advantage over rollers that they can transfer higher loads between pin and guide. For the sliding mating between pins and guide here comes a variety of material pairings in question, such as plastic plastic, plastic-metal, metal-metal, ceramic-metal, etc.

An embodiment of the bearing elements with roller, however, allows a particularly low-wear contact of pin and guide. The rollers can in turn be mounted with ball bearings, roller bearings, plain bearings or the like.

Furthermore, it may be advantageous for the positioning device to have at least one transverse centering and / or at least one longitudinal centering. A transverse centering is to be understood as meaning a device which aligns the movable carrier essentially in the transverse direction with respect to the course of the bridge. This is, for example, necessary if the movable bridge component shifts in the transverse direction through the process of opening and closing, for example due to tolerances in the storage. The same applies to the longitudinal centering, except that displacements of the movable carrier are substantially compensated in the longitudinal direction, for example, due to thermal deformations of the movable bridge component in the longitudinal direction. In this case, transverse centering and / or longitudinal centering can be bundled in one device, or there can be two separate devices each for transverse centering and for longitudinal centering. The functional combination of transverse centering and longitudinal centering can e.g. by a cylindrical pin which engages in a funnel as a guide can be realized. This bundling offers the advantage of the reduced number of parts and is therefore particularly economical. A separation of Querzentrierung and longitudinal centering allows optimal adjustment of the positioning device to the respective requirements, such as respective shifts.

It is advantageous if the positioning device is designed so that a defined, in particular minimal, edge gap between the solid bridge component and transition structure is generated. The smaller the edge gap at the closed bridge fails, the less the road is interrupted. For example, noises that occur when driving over the edge gap are minimized. Furthermore, the penetration of moisture and dirt into the bridging device is reduced by a minimal edge gap.

Furthermore, it may be advantageous that the positioning device has at least one force receiving device. A force receiving device is to be understood here as meaning a device which has forces, in particular horizontal, and / or moments receives, if necessary, between the movable support of the transition structure, as well as the fixed bridge component occur. The force receiving device consists, for example, of at least one arranged on the movable carrier force introduction element, for example in the form of a compression strut, which is in closed bridge with at least one attached to the fixed bridge component force receiving element in touch. Thus, with the bridge closed, horizontal forces can be introduced from the movable support or from the transitional construction into the fixed bridge component without deforming the positioning device. In particular, it may also be expedient to design the force receiving device in several parts. Thus, the positioning device can be practically embedded in the force receiving device.

It may be expedient that the force receiving device in turn has at least one transverse force bearing and / or at least one longitudinal force bearing. Under a transverse load bearing is to be understood as a bearing that absorbs particular forces and / or moments transverse to the direction of extension of the bridge. Such lateral forces can arise, for example, by lateral wind loads. The same applies to the longitudinal force bearing, which absorbs, for example, longitudinal forces that occur, for example. By a collision or deceleration of vehicles. Through a functional separation of transverse and longitudinal bearings, it is possible to optimally dimension both the lateral force bearing, as well as the longitudinal force bearing with respect to the forces occurring in each case. If, for example, strong lateral forces and only low longitudinal forces occur, it is possible to install a correspondingly large transverse force bearing in a longitudinally very compact bearing. On the other hand, a combination of lateral and linear bearings allows a particularly economical use since the number of parts of the bridging device is reduced.

It may be expedient that, in particular for smaller bearing forces force receiving device and positioning device are functionally combined in a device. By functional association, it is to be understood here that the positioning device is, for example, capable of accommodating not only the targeted positioning of the movable carrier but also the bearing forces occurring at this point, when the bridge is being driven, for example. Such functional association can be achieved for example by appropriately designed pins, bearing elements or guides. The contact surface between pin and guide is thus initially used for targeted positioning of the movable support and is then also able to absorb bearing forces. Conceivably, e.g. Rings on the pin.

Furthermore, it may be advantageous that, in particular in the case of medium and large bearing forces, the force-receiving device and the positioning device are functionally separated in different devices. This is to be understood that the Components that are responsible for positioning during the closing of the bridge, no longer have to absorb any bearing forces. Rather, a specially used and dimensioned force-absorbing device takes over the absorption of these forces. Especially with medium and large bearing forces, this may be expedient, since a correspondingly large dimensions of the pin, the guide or the bearing element is no longer possible or economical. In this case, it is more economical to separate the function of positioning from the function of power transmission.

It may be useful that the lock-up device at least one means for generating a distance between the pin and guide when the force receiving device is in engagement, has. The means may be, for example, a hydraulic or a corresponding geometric configuration of the contact surface. As a result, pin and guide are not in contact while the bridge is closed. This ensures that bearing forces that overload the pins - and thereby deform - could be absorbed by the force receiving device.

It may be appropriate for the transition structure to be a swivel cross-over construction. Under a swivel cross-transition construction is a device to understand in which a plurality of transversely to the direction of travel running slats are rotatably mounted to each other on at least one pivotable swivel traverse. A pivoting transom construction is therefore particularly suitable for large and complex movements as well as for use in earthquake-prone buildings.

Furthermore, it is advantageous that at least one movable carrier of the bridging device is a pivoting crosspiece of the swivel cross-member construction. In this case, thus directly the swivel traverse is brought by the positioning in position.

Furthermore, it may be advantageous for the transition structure to be a mid-beam transition construction. In the center-carrier transition construction, the lamellae, also referred to as center girders, are not arranged on pivoting traverses, but rather on traverses which are only longitudinally displaceable, usually arranged in parallel and longitudinally to the direction of travel. The distance of the slats can be controlled here so that the slats together in the sense of a chain moved together by pushing the slats, or by pulling forces receiving joint tapes that connect the slats together, are pulled one after the other. This construction guarantees a long service life and freedom from maintenance, which makes it particularly economical.

It can be advantageous that at least one movable support is designed as edge support, cross member and / or center support of the transition structure. The positioning device is therefore arranged directly on these components, which makes additional components unnecessary.

Furthermore, it may be expedient that at least one movable carrier is designed as a lifting carrier for the transitional construction. A lifting carrier is to be understood as meaning a carrier which is arranged in addition to the transitional construction and at least partially supports it if this is not connected to the fixed bridge component. Especially when large and heavy transitional structures such as swiveling trays are used, such a lifting carrier may be necessary. Since the swivel traverses are not yet used for movable bridges, the trusses are not actually dimensioned to take the load of the transitional construction, if this is not stored on one side. It therefore offers the possibility of either the existing carrier, such as swivel traverse or normal traverse, in the dimensioning and storage to adapt accordingly, or to use a separate lifting carrier. Depending on the load case, it is decided which of the two solutions is more economical.

It may be advantageous for at least one movable support to provide a support bearing on the movable bridge component, in which the corresponding movable support is guided. The support bearing can be adapted with respect to its degrees of freedom to the transition structure. That is, the movable support can only be moved in directions that allow the transition structure. Movements in other directions do not allow the carrier bearing so as to prevent damage to the transitional structure.

It makes sense that the lock-up device is waterproof. This e.g. by using waterstops between the lamellas. This prevents rainwater or in winter salt water from penetrating between the bridge components and running down from the bridge in an uncontrolled manner. It may be expedient that at least one rain discharge is arranged in the edge gap and / or in the guide. Even if the marginal gap is made as small as possible, it may happen that a minimum amount of surface water penetrates into this gap. This penetrating surface water can be derived by a rain drain, such as a gutter below the edge gap targeted. The guidance of the positioning device can come into contact with moisture when the bridge is open. For example, rain may enter the funnel of the guide. Again, therefore, a rain drainage may be appropriate.

It may be advantageous that the transition structure is arranged on the fixed bridge component. For example, if the movable bridge is a bascule bridge. So must the Transitional structure can not be moved with the movable bridge component. Especially in the case of hinged bridges, this avoids complete meshing, which would lead to noise pollution. In addition, with such a strong deflection of the transition structure, the later positioning becomes more difficult. Furthermore, the weight of the movable bridge part would increase, which is unfavorable for the bearings and the drives.

On the other hand, it may also be expedient that the transition structure is arranged on the movable bridge component. This is the case, for example, if there is little space on the fixed component for installing the transition structure. Especially when it comes to a lifting bridge or swing bridge, in which the movable part is moved only in one plane, a displacement of the transition structure by the movement is not expected.

As already mentioned above, the invention extends not only to the lock-up device as such, but also to a movable bridge equipped with a lock-up device according to the invention. Any types of movable bridges are contemplated such as e.g. Swing bridges, swivel bridges, lifting bridges and the like.

In the figures of the different embodiments, the same reference numerals are used for similar parts.

Fig. 1 shows a schematic representation of a lifting bridge according to the invention 5 with two fixed bridge components 3 and an intermediate movable bridge member 4, which can be raised and lowered. In the raised state while the clear height is increased under the movable bridge component 4, for example, to allow a greater clearance height. In the lowered state, however, the passage of the bridge over the movable bridge member 4 is made possible. In the lowered state of the movable bridge component 4 there are joint gaps 2 between movable bridge component 4 and fixed bridge component 3. These joint gaps 2 are each bridged by a bridging device 1 according to the invention, but which in FIG Fig. 1 due to the scale are not recognizable.

Fig. 2 shows a section through a first embodiment of such a bridging device according to the invention 1. In the sectional view, the movable bridge member 4 is just shut down. The bridging device 1 has a transitional construction 6, a movable support 7 and a positioning device 8.

To accommodate the weight of the transition structure 6 at least in the state of startup and shutdown, at least one lifting carrier 20 is mounted below the transition structure 6. The lifting carrier 20 is mounted on a first side on the movable bridge component 4. On a second side of the lifting beam 20, an edge support 18 of the transition structure 6, and a hollow box 21 is mounted next to the positioning device 8. Lifting carrier 20, positioning device 8, edge support 18 and hollow box 21 form a functional unit, which produce a targeted connection of the transition structure 6 on the side of the fixed bridge component 3 with the bridge closed. In this exemplary embodiment, a unit comprising at least lifting carrier 20, edge carrier 18 and hollow box 21 is thus to be understood as being under the movable carrier 7, which is specifically positioned by the positioning device 8.

In this case, remains in the shut down state of the movable bridge component 4, an edge gap 22 (in Fig. 2 not shown) between hollow box 21 and fixed bridge component 3. This edge gap 22 should be as small as possible to prevent the ingress of dirt and liquid and to ensure the smoothest possible road junction. For the smallest possible marginal gap 22, the positioning device 8 is ultimately responsible. The positioning device 8 has a pin 9 on the side of the movable bridge component 4. On the side of the fixed bridge component 3, the positioning device 8 on a guide 10, which is funnel-shaped in this embodiment.

Between pin 9 and guide 10, a bearing element 11 is arranged, which is presently attached to the pin 9. In the first embodiment, the bearing element 11 sliding plates 12 made of plastic. When lowering the movable bridge member 4, the pin 9 engages in the funnel-shaped guide 10 and is thereby selectively positioned. As a result, a minimal edge gap 22 between hollow box 21 and fixed bridge component 3 is ultimately made possible.

Furthermore, the bridging device 1 has a force receiving device 14. In the present case, the force receiving device 14 consists of two force introduction elements 14a which are aligned on the pin 9 and two force absorption elements 14b. Their arrangement allows on the one hand a lowering and lifting of the movable bridge member 4 in the vertical direction, on the other hand, however, forces and moments that arise when the bridge is closed, are recorded so that it does not damage about the edge support (18) or on the pin (9 ) comes. The forces and moments can arise, for example, by driving on the bridge with vehicles or by thermal expansion of the bridge components.

The transition structure 6 ensures a uniform roadway transition. In order to absorb the power of vehicles driving over, the transition structure 6 has a plurality of fins 28, which are arranged transversely to the direction of travel. Between the fins 28 of the transition structure 6 seals are mounted (in FIG. 2 not shown) which prevent the ingress of moisture. Liquids that penetrate into the guide 10 when the bridge is open are discharged through a rain outlet 23b. In addition, a rain discharge 23a below the edge gap 22 prevents moisture which penetrates through the edge gap 22 from getting into the bridging device 1 from below.

Fig. 3 shows a second embodiment of the lock-up device 1. This essentially corresponds to the first embodiment and differs mainly with respect to the positioning device used 8. While in the first embodiment, sliding plates 12 were used, in this case rollers 13 are used. These are particularly well suited for smaller bridges having smaller and lighter transition structures 6. These smaller transitional constructions 6 require lower forces for positioning. The rollers 13 ensure a smooth running into each other of pins 9 in the guide 10. In medium and large contact forces such rollers 13 are less suitable, since they can not transmit large enough forces. Through the interaction of the shape of pin 9 including roller 13, guide 10, force input element 14a and force receiving element 14b is achieved that in the lowered end position of the movable bridge member 4 no contact between leadership 10 and roller 13, but the upper end of the pin practically abuts the Krafteinleitelement. This ensures that in the closed state of the bridge no forces and moments act on the outer end of the positioning device 8, which could lead to an undesired deformation of the pin.

Fig. 4 shows a plan view of a part of a bridging device 1 according to the invention according to a third embodiment. In this case, the fixed bridge component 3, the edge gap 22, the hollow box 21, a transition structure 6 designed as a pivoting traverse transition structure 106, and the movable bridge component 4 can be seen from above. The lying under the blades 28 pivoting traverses 16, and the lifting beams 20 are shown in dashed lines. The pivoting traverses 16 are arranged slightly obliquely to the direction of travel and rotatably connected to the blades 28. By this arrangement, a uniform divergence and collapse of all slats 28 is ensured. The lifting beams 20 are movably mounted on the movable bridge member 4. On the one hand, they permit a movement of the pivoting-traverse transition structure 106 in the scope of the degrees of freedom intended for it. On the other hand, take the lifting beams 20 when starting up the bridge, the weight of the swivel cross-transition structure 106 together with hollow box 21. As a result, a corresponding guide is ensured and prevents overloading of the trusses 19.

Fig. 5 shows a section through the lock-up device 1 according to Fig. 4 along the line AA. Here, the various components of the lock-up device become clear, on the one hand provide the positioning when lowering the movable bridge component and on the other hand absorb the horizontal forces. The bridging device 1 in this case has a positioning device 8. The positioning device 8 is formed by a pin 9 and a guide 10 attached to the fixed bridge component 3. As bearing elements 11 slide plates are used. This makes it possible that the positioning device 8 serves as a lateral force bearing 26 at the same time. It thus assumes in the lowered state and forces that occur transversely to the direction of travel between hollow box 21 and fixed bridge component 3.

Since in this embodiment, the longitudinal forces occurring can be significantly higher than the shear forces, three separate longitudinal force bearing 27 are here attached, which are not all visible due to the sectional view. The separation of positioning device 8 and longitudinal force bearing 27 allows optimal dimensioning of the respective components.

Furthermore, a separate device for longitudinal centering 25 is attached. The functional separation of transverse centering and longitudinal centering also allows optimal Adaptation to the conditions (eg the gap to be bridged). For example, larger longitudinal displacements can be selectively positioned as transverse displacements. In order to accommodate the weight of the transitional structure 6 and the hollow box 21 when the bridge is opened, lifting beams 20 are also used in this case.
