Definitions

  • the present invention relates to a bridging device in lamellar construction for a building joint between a first building part and a second building part with a plurality of lamellas.
  • the bridging device has a hydraulic control device for controlling the gap width between the lamellae, the hydraulic control device having double-acting hydraulic cylinders, each with a movable piston and a piston rod arranged on the piston.
  • Each hydraulic cylinder is arranged on a lamella and each piston rod is connected to a different lamella.
  • the piston defines a first working volume and a second working volume of the corresponding hydraulic cylinder.
  • a lamella should also be understood to mean the edge support of a bridging device.
  • the building joints also known as movement joints or expansion joints, serve to compensate for movements of the building parts relative to one another, in order to prevent damage.
  • the structural parts can in particular be two parts of a bridge structure, e.g. Bridgehead or abutment and bridge support or bridge girder or adjacent bridge girders.
  • Such movements of the building parts towards one another are unavoidable and can occur, for example, due to thermal expansion or creeping and shrinking of the building materials used.
  • movements can also occur due to loads caused by the passage of people or vehicles, for example due to braking loads when braking vehicles. Shock loads occur especially in the case of heavy braking directly in the area of the bridging device.
  • bridging devices are used to bridge the building joint between the two parts of the building in such a way that vehicles and living beings can get safely from one part of the building to the next.
  • lamellar construction which is also known as central girder construction
  • the bridging device has a plurality of lamellae which are movably arranged on a crossmember mounted on the two structural parts.
  • So-called control devices are used in order to keep the variable gap widths between adjacent slats or a slat and an edge girder constant when the structural parts are moving.
  • control devices are regularly mechanically constructed, and are usually kinematically designed with a so-called swivel cross member or elastically with spring elements as a so-called girder grid joint.
  • a modular expansion joint consequently, the total gap to be bridged between the parts of the building is largely equally divided into several individual columns.
  • a disadvantage of these mechanical solutions is that, due to the inevitable flexibility, the necessary play and wear, incorrect control occurs, in which the variable gap widths are uneven. This in turn increases the wear and tear of the control device, generates an increased noise level when vehicles drive over the structural joint, and under certain circumstances can even lead to dangerous situations due to the gap width being too large.
  • Hydraulic control devices have the advantage that, due to the approximate incompressibility of the hydraulic fluid, a uniform gap width can be set between the lamellae or the lamellae and the edge supports.
  • the DE 2 060 482 A proposes to combine the working cylinders in pairs by connecting the first working volume of a first working cylinder to the second working volume of a second working cylinder and the first working volume of the second working cylinder to the second working volume of the first working cylinder.
  • the piston rod of the first working cylinder is connected to the lamella on which the second working cylinder is also arranged.
  • several control devices of this type each with two working cylinders, are used.
  • the DE 2 060 482 A also propose to use compressible pressure medium.
  • the bridging device is distinguished in particular from the prior art in that the hydraulic control device has at least three double-acting hydraulic cylinders which are connected to one another via a hydraulic connection, in that the first working volume of each hydraulic cylinder is hydraulically connected to the second working volume of another hydraulic cylinder , so that there is a hydraulic ring closure between the at least three hydraulic cylinders.
  • the double-acting hydraulic cylinders are hydraulic cylinders in which the first working volume and the second working volume are of the same size. This ensures that the volume of the hydraulic fluid flowing in and out is the same.
  • variable gap width between at least four lamellae or edge beams can be distributed uniformly with a relative movement of the structural parts. Due to the hydraulic ring closure, all hydraulic cylinders are directly connected to each other, so that the movement of a single hydraulic cylinder is directly transferred hydraulically to all other hydraulic cylinders. The total volume from the first working volume of a hydraulic cylinder and the second working volume of a connected further hydraulic cylinder remains constant. Due to the largely play-free direct transmission of the movement between the hydraulic cylinders, incorrect control is theoretically impossible. Furthermore, the hydraulic control device according to the invention can be used to implement a bridging device in which fewer hydraulic cylinders are necessary, since no hydraulic lamella has to be actuated by two hydraulic cylinders.
  • the hydraulic control device is designed to allow defined compensating movements.
  • the hydraulic control device can thus be specifically reduced in rigidity, so that blockages of the control device due to contamination or temperature-related changes in volume of the hydraulic fluid do not affect the functioning affect.
  • the hydraulic control device has a kind of "inner flexibility", so that a conscious play in the control of the gap widths can be realized.
  • the hydraulic connection has at least one flow resistance.
  • This can be designed, for example, as a throttle or orifice.
  • the hydraulic control device can be designed to be sluggish, or the gap widths can only be activated when a limit pressure is exceeded. This makes it possible to avoid unnecessary small movements that occur, for example, during extremely short-term peak loads. As a result, the maintenance intervals can be extended due to the reduced wear.
  • the at least one flow resistance is preferably arranged between the first working volume of a hydraulic cylinder and the second working volume of another hydraulic cylinder. It is also conceivable that a flow resistance is arranged between each first working volume of a hydraulic cylinder and the second working volume of another hydraulic cylinder.
  • the hydraulic control device is hydraulically preloaded. This means that the operating pressure of the hydraulic control device is increased compared to the ambient pressure. In this way, a particularly precise gap width control can be achieved since the hydraulic control device is extremely rigid in this case. Operating loads (for example, by accelerating or braking when passing over the bridging device) are in this case diverted directly into the building without moving the slats.
  • the bridging device has at least one hydraulic accumulator.
  • the hydraulic accumulator enables the operating pressure to be maintained, in particular when a pretensioned hydraulic control device is used. For example, a temperature-related change in volume of the hydraulic fluid can be compensated without the preloaded operating pressure rising or falling inadmissibly.
  • the at least one hydraulic accumulator expediently has a gas tensioning device and is in particular a bladder, piston or membrane accumulator.
  • Bubble, piston or diaphragm accumulators have the advantage that they are very efficient and have a very short reaction time to compensate for pressure fluctuations.
  • the at least one hydraulic accumulator is connected to the hydraulic control device via a check valve. It is particularly expedient here if an orifice check valve is used. A control of the control device that takes place as a result of a short-term increase in pressure can thus take place without problems, whereas slow pressure increases - for example due to temperature changes - are compensated for by the hydraulic accumulator. Slow increases in pressure are thus compensated for by the hydraulic accumulator, and a drop in pressure is compensated immediately. An empty running of the lines is therefore largely impossible. In particular, it is therefore expedient if the inflow to the hydraulic accumulator takes place via the orifice, whereas the outflow essentially runs via the check valve.
  • the hydraulic control device has hoses for connecting the working volumes of the hydraulic cylinders.
  • Hoses have the advantage that they are flexible and can therefore follow the movements of the lamellae or the hydraulic cylinders relative to one another without causing tension or wedging. Furthermore, this also facilitates the installation of the hydraulic control device, in particular if the hydraulic control device is retrofitted. It is also conceivable that at least some pipes, for example with rotary connectors or a telescopic mechanism, are used.
  • the hoses are expediently connected to the hydraulic cylinders via couplings, in particular plug-in couplings. This facilitates the maintenance, replacement, installation and filling, filling and venting of the hydraulic control device.
  • At least one piston rod is articulated to the lamella.
  • a swivel joint with one axis or also a joint with several degrees of freedom e.g. a ball joint or a socket joint is used.
  • the hydraulic cylinders are fixed in a thrust-resistant manner but rotatably on the lamellae or on the edge supports.
  • the hydraulic cylinders are articulated to the fins. As a result, essentially all non-linear movements can be recorded without causing damage.
  • the hydraulic control device expediently has at least one connection for a pump.
  • the slats can be moved apart or moved together, for example, during maintenance.
  • the hydraulic preload can also be adjusted or readjusted if necessary.
  • filling or filling the system can be simplified by connecting the pump. It is advantageous here if the connection is arranged in the area of a coupling.
  • the bridging device has a monitoring device for the detection of pressure changes. It is particularly advisable to monitor the pressure of the hydraulic control device via suitable sensors of the monitoring device, so that a leak or a line break can be detected at an early stage.
  • the bridging device has at least one mechanical and / or elastic control device, in particular a swivel cross member.
  • the hydraulic one Control device is advantageously intended to assist in order to achieve a uniform distribution of the gap widths.
  • At least one hydraulic cylinder is a first hydraulic cylinder with a first cross section and if another hydraulic cylinder is a second hydraulic cylinder with a second cross section, the first cross section being different from the second cross section.
  • the sum of the first working volume and the second working volume of the first hydraulic cylinder is equal to the buzzer of the first working volume and the second working volume of the second hydraulic cylinder.
  • the cross section of the first hydraulic cylinder is larger or smaller than the cross section of the second hydraulic cylinder. This further results in a smaller piston stroke in the hydraulic cylinder with the larger cross section than in the hydraulic cylinder with the smaller cross section.
  • a hydraulic ring closure can still be achieved due to a constant product of cross-sectional area and piston stroke.
  • FIG. 1 A partial area of a bridging device 1 in a lamella construction is shown.
  • the bridging device 1 bridges a building joint between two building parts (not shown).
  • the bridging device 1 has a plurality of slats 2 which are movable relative to one another.
  • the bridging device 1 has a hydraulic control device 3.
  • the hydraulic control device 3 is provided for controlling the gap widths S between the slats 2.
  • the hydraulic control device 3 consists of three double-acting hydraulic cylinders 4.
  • the hydraulic cylinders 4 are all constructed identically, so that the structure of a hydraulic cylinder 4 is described below.
  • the hydraulic cylinder 4 has a piston 5 and a piston rod 6, which is connected to the piston 5 in a thrust-resistant manner.
  • the piston 5 defines a first (variable) working volume 7a and a second (variable) working volume 7b in the hydraulic cylinder 4.
  • Each hydraulic cylinder 4 is connected to a lamella 2 (or an edge support (not shown here) on the structural part).
  • the hydraulic cylinder 4 is fixed to the plate 2 by means of a clamp 8.
  • the clamp 8 is designed such that the hydraulic cylinder 4 is rotatably mounted about its vertical axis and about its transverse axis.
  • the hydraulic cylinder 4 is a synchronous cylinder in that the piston rod 6 extends on both sides of the piston 5.
  • the piston rod 6 is articulated at one end 9 to a second plate 2.
  • the end 9 of the piston rod 6 is articulated to the lamella 2, which is directly adjacent to the lamella 2, on which the hydraulic cylinder 4 having the piston rod 6 is arranged.
  • the hydraulic cylinders 4 are connected to one another via a hydraulic connection 10.
  • the hydraulic connection 10 consists of three hoses 11, the ends of which are each hydraulically connected to a working volume 7a, 7b of a hydraulic cylinder 4 via a coupling 12.
  • a first working volume 7a of a hydraulic cylinder 4 is always hydraulically connected to the second working volume 7b of another hydraulic cylinder 4 via a hose 11. This creates a hydraulic ring closure between the hydraulic cylinders 4.
  • the hydraulic ring closure of the hydraulic cylinders 4 requires a uniform gap width S between adjacent slats 2 or between a slat 2 and the (not shown) edge support of a part of a building or bridge. Since the total volume of a hydraulic cylinder 4 always consists of the first working volume 7a and the second working volume 7b, the total volume remains constant when the piston 5 - and therefore also the piston rod 6 - moves. Furthermore, the total volume also corresponds to the sum of the volume of the first working volume 7a of a hydraulic cylinder 4 and the volume of the second working volume 7b of the other hydraulic cylinder 4 connected thereto via the hose 11.
  • a second embodiment is shown as a plan view.
  • This exemplary embodiment essentially corresponds to that in FIG 1 and 2 Embodiment shown, wherein the hydraulic control device 3 has a total of six hydraulic cylinders 4. A total of seven lamellae 2 or five lamellae 2 and two edge supports are controlled via these six hydraulic cylinders 4.
  • the first working volume 7a of a hydraulic cylinder 4 for example that in FIG Fig. 3 and Fig. 4 as the bottom hydraulic cylinder 4
  • the second working volume 7b of the directly adjacent hydraulic cylinder 4 hydraulically connected via the hose 11
  • this promotes clarity and allows an improved response behavior, since the volumes in the tubes 11 can be kept low.
  • the gap width S both when the bridging device 1 has moved apart (cf. Fig. 3 ) as well as in the closed state of the bridging device 1 (cf. Fig. 4 ) is identical between the slats 2 or between a slat 2 and an edge support.
  • the second exemplary embodiment of the bridging device 1 differs from that in FIG 1 and 2
  • the embodiment shown is also characterized in that the hydraulic cylinder 4 shown at the bottom has a further connection 13 for an external (not shown) pump in the area of the coupling 12 of the first working volume 7a.
  • a this connection 13 adjacent lamellae 2 of the bridging device 1 can be moved apart or moved together in a targeted manner by changing the operating pressure of the hydraulic control device 3 at the corresponding point via the pump. This can be necessary for function tests or maintenance work, for example.
  • FIG Fig. 5 A third exemplary embodiment of a bridging device 1 according to the invention in plan view is shown in FIG Fig. 5 shown.
  • the bridging device 1 largely corresponds to that in FIG Fig. 3 Bridging device 1 shown, wherein the hydraulic control device 3 has a total of twelve hydraulic cylinders 4.
  • the hydraulic control device 3 has a total of twelve hydraulic cylinders 4.
  • the twelve hydraulic cylinders 4 are also connected via a hydraulic connection 10 Hoses 11 connected to a hydraulic ring closure.
  • the first working volume 7a of a hydraulic cylinder 4 is connected to the second working volume 7b of another hydraulic cylinder 4.
  • the embodiment shown here is a lamella 2 controlled by two hydraulic cylinders 4.
  • two piston rods 6 are each hingedly connected at their ends 9 to the five central lamellae 2 (ie not to the edge supports, which are formed by the two outer lamellae 2 in this exemplary embodiment).
  • Such double actuation of the slats 2 by the hydraulic control device 3 is advantageous in the case of relatively large bridging devices 1, for example in order to prevent the slats 2 from tilting in the case of wide structural joints to be bridged.
  • FIG. 6 A fourth exemplary embodiment of a bridging device 1 according to the invention is shown.
  • the bridging device 1 has a total of four separate hydraulic control devices 3, each of which in turn has three double-acting hydraulic cylinders 4.
  • the three hydraulic cylinders 4 of each hydraulic control device 1 are connected via a hydraulic connection 10 by means of hoses 11 to form a hydraulic ring closure.
  • a plurality of hydraulic control devices 3 with hydraulic ring closure are provided in this exemplary embodiment.
  • a monitoring device 14 is provided in this sixth exemplary embodiment.
  • This monitoring device 14 monitors the operating pressure of the hydraulic control devices 3.
  • the hydraulic connection 10 is monitored via corresponding sensors 15. If a drop in pressure within the hydraulic connection 10 is detected, the monitoring device 14 indicates this. This is indicated as an example with dash-dotted lines for the uppermost hydraulic control device 3 shown. Of course, the monitoring device 14 monitors all hydraulic control devices 3 of the bridging device 1.
  • the monitoring device 14 is designed to recognize short-term pressure fluctuations as a result of the movement of the structural parts.
  • the monitoring device 14 shows no leakage in the event of these short-term pressure changes.
  • the monitoring device 14 can only indicate a leak if the operating pressure does not correspond to the target pressure over a certain period of time. In this way, a gradual drop in operating pressure can be detected early.
  • flow resistances 16 are also provided in the hydraulic connection 10 in the hydraulic control device 3 shown as the lowest.
  • the flow resistances 16 are arranged as orifices in the tubes 11.
  • the Flow resistances can specifically make the hydraulic control device 3 slow, so that short-term loads do not lead to any movement in the bridging device 1. This is relevant if the hydraulic control device 3, as shown, does not require any hydraulic preload (cf. also here Fig. 9 ).
  • several flow resistances 16 can be provided. It is also conceivable that only one flow resistance 16 is provided. It is also conceivable that the flow resistance 16 is designed as a valve unit on the clutch 12.
  • FIG Fig. 7 A fifth exemplary embodiment of a bridging device 1 according to the invention is shown in FIG Fig. 7 shown.
  • the hydraulic control device 3 is used to support a mechanical control device 17 in the form of a swivel crossmember.
  • the swivel traverse 17 primarily controls the gap widths S between the slats 2 in a conventional and known manner.
  • the hydraulic control device 3 in this exemplary embodiment consists of three hydraulic cylinders 4 and is essentially analogous to that in the first exemplary embodiment according to FIG Fig. 1 shown hydraulic control device 3 constructed. The difference can be seen in the fact that the hydraulic control device 3 controls only every second lamella 2 according to the fifth exemplary embodiment.
  • the hydraulic control device 3 is therefore provided to support the swivel crossmember 17 and minimizes the possibility of incorrect control.
  • This fifth exemplary embodiment is particularly suitable as a retrofit solution for existing bridging devices 1, since the actual control of the gap widths S takes place mechanically via the swivel cross member 17. Nevertheless, incorrect controls can be largely avoided.
  • FIG. 8 A sixth exemplary embodiment of a bridging device 1 according to the invention is shown.
  • the bridging device 1 has an analogous to that in FIG Fig. 7 Embodiment shown a mechanical control device 17 in the form of a swivel crossbar.
  • the hydraulic control device 3 is used to support this.
  • the difference to that in Fig. 7 Bridging device 1 shown consists in that the hydraulic control device has two first hydraulic cylinders 4a with a first cross section and two second hydraulic cylinders 4b with a second cross section. As shown, the first hydraulic cylinders 4a control the directly adjacent lamella 2, whereas the second hydraulic cylinders 4b control the second lamella 2.
  • the shorter control stroke necessary for this with a correspondingly shorter piston rod 6 of the first hydraulic cylinders 4a is achieved by a larger cross section compared to the second hydraulic cylinder 4b.
  • the hydraulic ring closure of the hydraulic cylinders 4a, 4b results from the constant product of cross-sectional area and piston stroke, which is identical for the first hydraulic cylinders 4a and for the second hydraulic cylinders 4b. Incorrect controls, in particular in the area of the first hydraulic cylinders 4a, are thus largely avoided.
  • a hydraulic control device 3 designed in this way for support A mechanical control device 17 or an elastic control device is particularly suitable for bridging devices 1 with a longitudinal gradient.
  • a sixth embodiment of a bridging device 1 according to the invention is shown, in which the hydraulic control device 3 is hydraulically preloaded, that is to say has an increased operating pressure. Due to the hydraulic preload, the hydraulic control device 3 responds particularly quickly and precisely.
  • the hydraulic control device 3 essentially corresponds to that in FIG Fig. 1 shown hydraulic control device 3, wherein the hydraulic control device 3 has a hydraulic accumulator 18 with gas tensioning device.
  • the hydraulic accumulator 18 can be a membrane-bubble or piston accumulator, for example.
  • the hydraulic accumulator 18 is connected via a spring-loaded orifice check valve 19 to the hydraulic control device 10 via corresponding connecting lines 20, which can be connected to a hose 11 as shown.
  • a compensating volume is thus created, as a result of which, for example, a temperature-related change in volume of the hydraulic fluid can be compensated. An inadmissible increase or decrease in the operating pressure is therefore prevented.
