    Device for the storage of bridge constructions, in particular a horizontal force Laoer ausaebildet as Füh-runaslaaer
    The invention relates to a device for supporting bridge structures, in particular a horizontal force bearing designed as a guide bearing, wherein at least one spherical bearing is arranged between an overlay and a substructure.
    Bearings, even if sized and installed according to the rules, have a shorter life than the main structure. Therefore, railway bridge bearings are generally to be planned as interchangeable construction products. This interchangeability must already be taken into account and represented in the planning of the construction measure in a stock change concept.
    From DE 10 2004 062 581 B3 an elastomer bearing is known as the prior art, which serves as a roadway storage at the junction of two bridge sections of a transportable bridge.
    JP 2006-226 449 A describes a bridge bearing, which in each case has a dowel disk at its lower and upper area. Anchoring takes place via a shear anchorage. The shear anchorage engages in vulcanized plates of the elastomeric bearing and anchors the bearing with the adjacent lateral plates, which are made split. In addition, a thick steel plate, which ensures the removal of scheduled horizontal loads, is vulcanised into the elastomer bearing. Due to horizontal loads, the elastomeric pad deforms until a contact between the stop and the vulcanized plate is made. There are no separate shots for the dowel plate (s) provided on the bearing base. The support has metal components that are not completely covered by the elastomer. Thus, there is no adequate corrosion protection for this purpose and for the laterally arranged, divided boundary plates.
    From JP 09-100 511 A a device for supporting a bridge section is known, in which between a superstructure and a bearing base each support plates are arranged, which rest against a one-piece elastomeric bearing. At the lower support plate a dowel plate is fixed, which 2 ···· «·· * ·
    engages in a recess of the bearing base. Since the support described also transfers horizontal forces (see Figures 6, 8 and 12), the two support plates after completion of the bearing firmly connected to the superstructure or the support base (see Figures 8, 12 and 13). The dowel plate is not integrated in the elastomer cushion. There are also no separate shots for the anchor plate (s) provided on the bearing base.
    All known elastomeric bearings have the disadvantage that they are each used only for special applications, have too low durability, are replaceable only with great effort and only in exceptional cases without track closures and require the use of a special company.
    Railway undertakings are particularly interested in developing equipment elements that can be used to optimize the lifecycle costs of the infrastructure. Therefore, around the framework of the project standardization of bearings, a pilot camp was developed.
    The following assumptions were used as the basis for the development of the guide bearing: • The removal of the bearing forces should be constraint-free. • They should be usable for a variety of structures. • The storage must meet the economic constraints. • The warehouse construction should be solid, easy to maintain and durable. • The warehouse construction should be feasible in short construction times and with little damage to the construction site. • The bearing design should be readjusted or exchanged as easily as possible under "rolling wheel". • The bearing design should have a high degree of prefabrication so that it can be maintained as an overall system for maintenance. • The bearing design should be suitable for single-span structures with a span of up to 40 m. 3 · Μ · · • • • • • • • • • • • • • • •.
    The invention has for its object to develop a guide bearing, which allows to ensure a low-constraint removal of the bearing forces to be used on a variety of structures and which 5 can be easily installed, readjusted and expanded under the "rolling wheel".
    This is inventively achieved in that in a solid superstructure either on the superstructure over at least two tie rods 10 secured upper anchor plates or in a steel superstructure screws are arranged, which are fastened to at least one pressure plate, wherein on each pressure plate a stiffness is arranged, the a front plate is supported by which at least one pressure screw and at least one clamping screw are guided, wherein the pressure screws are supported via cylindrical recesses 15 and the clamping screw via a pressure piece and a spring on the back of a dome, which engages in the ball socket, the ball socket itself is supported on at least one sliding layer and / or a sliding plate on a steel box, which is fastened via its base plate with at least one head bolt dowel and at least two tie rods on the substructure 20.
    It is a standardized storage system in which the vertical and horizontal bearing forces are assigned to different standardized storage systems. 25 By separating the bearing force components, it is possible to divide the individual bearings into classes.
    The vertical component is derived by four reinforced elastomeric bearings per superstructure in the abutment. The support pedestals on the support bench are part of this system for bearing assembly. The bearing pedestal is prefabricated as a prefabricated part and considered together with the elastomer and the upper composite panel as an overall system. The elastomer is secured with dowel washers against displacements on the bearing base.
    The horizontal bearing forces are derived from the vertical force bearings by separate constructions. It is a guide bearing. • t ··· »··· #
    Floating storage is used up to a span of 30 m. Here, a Führungsiager for deriving the horizontal forces is provided on each abutment. Over a span of 30 m, a retaining structure has to be installed on an abutment and a guide bearing on the opposite abutment. Führungsiager
    For safe removal of the horizontal forces acting transversely to the direction of travel on the superstructure, a guide bearing is arranged for structures under 30 m span on each abutment. As a result, a floating storage for overbuilding is realized. The displacement paths are divided into two guide bearings. For structures with a span between 30 m and 40 m, a fixed point bearing is to be arranged on an abutment and a guide bearing on the opposite abutment. In this case, all length changes must be made possible by the guide bearing.
    The guide bearing is placed between the vertical force bearings on the Auflagerbank. The position should be in the middle. Another position may be for design reasons, e.g. so that the tie rods between the rolling beams of a WIB beam can be anchored in the superstructure, be selected.
    The largest displacements amount to approx. 105 mm. This shift must be made possible without affecting the structure by the guide bearing.
    The bearing consists of two lugs, which are anchored in the superstructure via an anchor plate. On the abutment a concreted steel box is embedded in concrete, which sits between the lugs and derives the forces into the abutment. The power transmission between the lugs and the steel box is made possible by a dome construction that can accommodate twists and displacements. The orientation of the entire construction is transverse to the longitudinal axis of the building. 5 · «9 4 ♦ ** ♦ ** ··» 1 «* * 4 · ·« «• 4 4 4 4 4 I '1 9 4 4 4 4 4 4 4 4 4 * ψ 4 4 4 4 9 4 4 4 44 444 444 9 4
    The lugs, which absorb the forces from the superstructure, are connected by bolts to the anchor plate. This makes them completely removable. Through the base plate, the knob is fastened with screws in the anchor plate 5 te. In the rib-supported front plate four nuts are pressed. The calottes are now biased against the steel box by threaded bolts threaded through the nut.
    The calf bearing consists of two parts, the ball segment supported by the screws from the collar and the corresponding ball socket, which rests against the steel box with its rear side. In the ball socket sliding materials are chambered on the straight and on the concave side of the ball socket, which on the one hand allow the rotation and on the other the displacement. 15 The steel box is machined on the two sides where the calottes rest. This creates the flatness of these surfaces. On these surfaces an austenitic sheet metal is screwed on as a sliding partner. On this sheet slide the ball pans and allow the longitudinal displacements of the superstructure. In addition, lubricants are introduced into recesses 20 of the concave and / or the convex part of the ball socket of the spherical bearing.
    Assembly of the guide rail 25 When concreting the support bench, a recess must be provided for the subsequent casting of the tie rods and the head studs. In the recess in the course of reinforcement work, the tie rods are loosely installed at the intended location. Due to the high reinforcement density in the area of the force application, it is not possible to install the tie rods after the reinforcement work. The recess should be made by means of expanded metal (or similar). The reinforcement is to be completely installed. The steel box should also be placed only loosely at the intended location and the tie rods are made through the holes provided. The washers and nuts are to be used for temporary securing. 35 i ····· * «··· · 6

    The drawer is embedded in the recess of the support bench. To secure the position during the concreting process auxiliary structures have to be screwed on at the side. The auxiliary structures have set screws on which the steel box is placed. The height and alignment is possible by adjusting the screws. The steel box is cast with all components in the recess. The maximum directional deviation of the sliding surfaces must be limited to 0.01 rad.
    The tie rods, which are covered with heat shrink tubing, must be installed. The tie rods take over the anchoring of the offset torque. The thrust is introduced via head bolt dowels in the Auflagerbank. After hardening of the concrete of the Auflagerbank the tie rods are biased. The steel box is concreted with unreinforced concrete.
    Installation in the massive superstructure
    The anchor plate, for the attachment of the lugs, is installed in the superstructure with the tie rods and the nuts, which are secured by bolts for the construction period. The thrust is also initiated via dowel bolts. The directional deviation of the anchor plate / lobe must not exceed 0.01 rad.
    The tie rods of the anchor plate are covered with heat shrink tubing. The force is introduced only with the anchoring plate at the end of the tie rods. Oetzbaumontaqe by insertion / lifting
    When mounting the superstructure by inserting or lifting, there is the possibility to mount it in the final position of the superstructure for the lugs, which are attached to the superstructure. It follows that the shifting of the superstructure can only take place at a low height above the end position. For the assembly of the lugs, the screws, which served for the construction time as a positional backup, removed. The lugs are assembled and the dome construction installed. 7 • · ♦ ♦ ·· «··· ·
    The knobs are placed on the setscrews that remain in the front panel. The lugs can be brought by the screws in the correct position to facilitate installation. The screws are installed and preloaded by a tightening instruction shown by method test 5. Due to the design construction tolerances can be compensated in the horizontal. Superstructure manufacture in final position 10 When producing the superstructure in its end position, the anchor plate can be installed with mounted lugs. All threads must be secured against dirt by screws for the construction period. In the bottom of the front panel are two setscrews, which are provided for adjusting the built-in part included. On these screws, the construction is placed on the support bench 15 and aligned in the spatial position. The horizontal position assurance is to be ensured by the formwork. After the production of the superstructure, even before stripping the screws are screwed into the front panel, so they do not transmit vertical loads. The final assembly of the sliding plates and the Kalottenkonstruktion takes place as soon as no pollution is 20 expected by the construction process more and the superstructure has the necessary strength.
    Assembly on composite and steel superstructures 25 The drawer is cast in during the production of the support bench. The tie rods, which are covered with heat shrink tubing, must be installed. The tie rods take over the anchoring of the offset torque. The thrust is introduced via head bolt dowels in the Auflagerbank. After hardening of the concrete of the Auflagerbank the tie rods are tensioned pre-30. The steel box is concreted with unreinforced concrete.
    The anchor plate is bolted or welded to the end cross member. The welds transmit the shear forces. The tensile forces from the offset moment are introduced by screws or threaded rods into the locally reinforced end cross member. The load introduction into the end cross member is to be ensured by the planning structural engineer and the loads are to be tracked further. Uberbaumontaqe by insertion / lifting

It follows that the shifting of the superstructure can only take place at a low height above the end position. The lugs are assembled and the dome construction installed. The knobs are placed on the setscrews that remain in the front panel. The lugs can be brought by the screws in the correct altitude to facilitate installation. The screws are installed and pretensioned by means of a tightening instruction. Due to the design construction tolerances can be compensated in the horizontal.
    Replacement of wearing parts in the driver's cab
    Only the sliding disks are to be regarded as wearing parts in the present construction. For the replacement, the superstructure in the guerrichtung must be determined by a secondary construction. An interpretation of the auxiliary construction is not possible because the storage system can be used on a variety of superstructures. The secondary holding should be adapted to the Überbauart and the forces occurring. The actual replacement takes place by turning back the four pressure screws and the pressure screw with spring. As a result, the dome is released and can be removed from the bearing structure. The sliding washers can be renewed and the calotte can be reinstalled after a visual inspection. After replacing the sliding discs of both calottes and einstetlen the bearing, the guide bearing is ready for use again. The superstructure can be released and the secondary containment removed. «« 9
