Definitions

  • the present invention relates to the use of a structural sliding bearing for connecting a first and second structural part.
  • Structural sliding bearings of this type typically comprise a lower bearing section that can be connected to the first structural component, a sliding plate that can be connected to a second structural component, and an intermediate bearing section located between the lower bearing section and the sliding plate.
  • the main sliding surface of the structural bearing is usually located between the intermediate bearing section and the sliding plate, along which the sliding plate can slide when the structural sliding bearing is in use.
  • the documents CN 108 532 451 A , DE 35 17 895 A1 , DE 101 28 362 A1 and DE 40 39 523 A1 show generic structural sliding bearings.
  • the document CN 108 532 451 A discloses a V-shaped, trough-like rubber pad for a slideway.
  • the V-shaped trough-like rubber pad for the slideway comprises an upper seat plate rubber layer, an upper seat plate, a rubber plate, a copper sealing ring, a lower seat plate, a lower seat plate rubber layer, a middle plate, a slide plate, and a stainless steel plate.
  • the upper seat rubber layer is vulcanized onto the surface of the upper seat plate
  • the lower seat plate rubber layer is vulcanized onto the surface of the lower seat plate.
  • the lower surface of the upper seat plate protrudes in a V-shape to form a protruding V-shaped lower portion; the upper surface of the middle plate is depressed in a V-shape to form a depressed V-shaped groove; the V-shaped lower portion of the upper seat plate is embedded in the depressed V-shaped groove of the middle plate; and the slide plate is vulcanized onto the upper surface of the middle plate.
  • a cap-type plain bearing is known. This comprises two tilting strips arranged on either side of the cap 1 and running parallel to one another, forming essentially vertical support surfaces between a sliding plate 5 and a bearing base 4.
  • the tilting strips each consist of a cover strip 7, which is arranged circumferentially with play in a groove 12 of the bearing base 4.
  • the cover strip 7 protrudes from the groove 12 and the space between the cover strip 7 and the groove base is filled with an elastomer insert 11.
  • the cover strip 7 is rotatable both about its longitudinal axis and about the vertical axis of the bearing, so that no crushing of the support surfaces occurs during such movements of the bearing.
  • the document DE 101 28 362 A1 discloses a bearing system for supporting a plurality of successively arranged guideway girders 2, which together form a track 1 of a high-speed railway 3 resting on a substructure.
  • the bearing system for a guideway girder 2 comprises three bearing units 4, 5, 6, each consisting of two bearings located opposite one another in the central longitudinal plane of the guideway girder 2.
  • the high-speed railway 3 causes a sinusoidal oscillation 8, so that the girder deflects accordingly between the bearing pairs 4, 5, 6.
  • a sliding bearing for construction purposes is known.
  • This has two vertical supports 17 arranged parallel to the sliding direction and to each other between a sliding plate 15 and a bearing base 14.
  • the supports 17 fit into grooves with stop ends from which tilting rails protrude.
  • Between each rail and the bottom of the groove is a compact insert made of synthetic rubber.
  • Each profile element 1 has a closed bore with two openings on the support side, which forms the groove for receiving the tilting rails.
  • Structural bearings generally transfer vertical and horizontal loads and allow for rotations and relative displacements where necessary.
  • Structural sliding bearings are a special type of structural bearing, which generally serve the defined and, if possible, constraint-free support of any type of structure, such as bridges, particularly in road and rail traffic, beams and buildings of any kind, or parts thereof. They therefore allow for relative movements between two structural components of the structure in question, which can arise, for example, through the use of the structure or through possible external influences such as wind or an earthquake.
  • the use of such structural bearings or corresponding structural bearing systems can thus prevent damage to the corresponding structures.
  • Structural bearings can be designed either as bearings that are fixed on all sides or that can be moved in all directions or in one direction.
  • a guided bearing is converted into a fixed bearing by means of locking devices.
  • the present invention relates in particular to uniaxially guided or unidirectionally movable structural sliding bearings, which thus enable a sliding movement of the sliding plate along a specific axial direction of the main sliding surface.
  • Fixed bearings that are subsequently converted are also relevant to the present invention.
  • Such uniaxially guided structural sliding bearings can be implemented, for example, as pot bearings or spherical bearings. Both types of structural sliding bearings are shown schematically in the Fig. 1 and 2 shown and are briefly explained below.
  • Fig. 1 shows a uniaxially guided structural plain bearing in the form of a pot bearing 10, also called a pot-shaped plain bearing, as is known from the prior art.
  • the pot-shaped plain bearing 10 has a pot 12 as the bearing base, which can be connected to a first part of the structure.
  • the pot 12 contains a machined recess 14 for receiving an elastomer cushion 16, an inner seal 18, and a pot cover 20, which represents the intermediate bearing part of the pot-shaped plain bearing 10.
  • the pot cover 20 closes the opening of the pot 12 and lies flush with the elastomer cushion 16 arranged underneath.
  • the sliding plate 22, which can be connected to a second structural part, is arranged above the pot cover 20.
  • Both the pot lid 20 and the sliding plate 22 are aligned horizontally, so that a horizontal main sliding surface 24 of the pot sliding bearing 10 extends between these two components.
  • a sliding material 26 is arranged on the pot lid 20 to reduce the friction between the pot lid 20 and the sliding plate 22. This enables the sliding plate 22 to slide along the main sliding surface 24 with as little resistance as possible.
  • the pot sliding bearing 10 can thus absorb vertically acting forces or loads via the sliding plate 22, the horizontal main sliding surface 24, the pot lid 20 and the elastomer cushion 16 and transfer them to the pot 12 below.
  • the elastomer cushion 16 enables any rotation of the pot sliding bearing 10. This occurs through selective yielding of the elastomer cushion 16 in the area of the force applied by the pot lid 20.
  • the inner seal 18 is arranged in such a way that the elastomer cushion 16 can be prevented from being pressed out through the gap between the pot wall and the pot lid 20 as soon as a pressure load is applied to the elastomer cushion 16.
  • an outer seal can be arranged between the pot lid 20 and the pot 12 to keep moisture and dirt away from the corresponding gap.
  • the pot sliding bearing 10 has a central guide rail 28 to realize the uniaxial displaceability of the sliding plate 22.
  • the central guide rail 28 is arranged above the pot lid 20 in the area of the main sliding surface 24 and engages with a corresponding groove in the sliding plate 22.
  • the guide rail 28 defines the axis of movement of the pot sliding bearing 10, as it can absorb all horizontal forces transverse to the sliding direction.
  • the two sliding surfaces between the guide rail 28 and the sliding plate 22 are arranged vertically along the axis of movement.
  • horizontally acting forces impact the central guide rail 28 perpendicularly from both sides and can thus be effectively absorbed.
  • the guide rail 28 also has an initially lubricated sliding material 30 along both vertical sliding surfaces. The friction between the guide rail 28 and the sliding plate 22 is thus reduced and movement of the sliding plate 22 along the axis of movement is facilitated.
  • FIG. 2 A uniaxially guided structural sliding bearing in the form of a spherical bearing 110 is shown, as is known from the prior art.
  • the spherical bearing 110 has a bearing base 112 that can be connected to a first part of the structure.
  • the spherical bearing 110 includes a spherical cap 114, which represents the intermediate bearing part of the spherical bearing 110.
  • the spherical cap 114 is convexly curved downwards and is received in a correspondingly concave section on the upper side of the bearing base 112.
  • a secondary sliding surface 116 of the spherical bearing 110 is thus formed between the spherical cap 114 and the bearing base 112.
  • a sliding material 118 is arranged in the area of the secondary sliding surface 116 to enable the spherical cap 114 to move with as little resistance as possible within the concave section of the bearing base 112.
  • Above the spherical cap lies the sliding plate 120, which can be connected to a second part of the structure.
  • the horizontal main sliding surface 122, or primary sliding surface, of the spherical bearing 110 is located between the spherical cap 114 and the sliding plate 120.
  • a sliding material 124 is arranged on the spherical cap 114 in the area of the main sliding surface 122 to reduce the friction between the spherical cap 114 and the sliding plate 120. This also enables the sliding plate 24 to slide along the main sliding surface 122 with as little resistance as possible.
  • the spherical bearing 114 can thus absorb vertically acting forces or loads via the sliding plate 120, the horizontal main sliding surface 122, and the spherical cap 114 and transfer them to the bearing base 112. At the same time, the convex curvature of the spherical cap 114 and the receiving concave section of the bearing base 112 enable corresponding rotations of the spherical cap 114 or the spherical bearing 110. This occurs here by the spherical cap 114 sliding along the secondary sliding surface 116.
  • the uniaxial guidance of the spherical bearing 114 is realized by two horizontal lateral guide rails 126. These are each arranged laterally next to the main sliding surface 122 on the lower bearing part 112 in order to engage with the sliding plate 120.
  • any horizontal forces transverse to the two lateral guide rails 126 are absorbed, thereby defining the movement axis of the spherical bearing 110.
  • the sliding surfaces between the two lateral guide rails 126 and the sliding plate 120 are each formed vertically along the movement axis. Due to the vertical action of the horizontal forces on the sliding surfaces of the two guide rails 126, even higher forces can be effectively absorbed.
  • the two lateral guide rails 126 have a sliding material 128 in the area of the vertical sliding surfaces, which is initially lubricated.
  • the friction between the two guide rails 126 and the sliding plate 120 can thus be significantly reduced, which simplifies the movement of the sliding plate 120 along the movement axis accordingly.
  • the serviceability limit state extends up to and including the serviceability limit state. Beyond this limit state, the specified conditions for the serviceability of a structure or component are no longer met. Therefore, limit states that affect the function of the structure or one of its components under normal service conditions, the well-being of the occupants, or the appearance of the structure are also classified as serviceability limit states.
  • the service condition may still exist when the extreme condition occurs. This applies in particular to the condition after the activation of any emergency and buffer functions, which are only used in extreme cases. In this case, for example, a targeted lifting of the sliding plate from the bearing intermediate part is provided during the service condition.
  • any orientations of surfaces, axes, and forces are described here as horizontal or vertical, these are not limited to a horizontal or vertical plane or direction in the narrower sense.
  • orientation specifications refer only to the plane of movement of the structural sliding bearing or structural bearing system. This applies in particular if the structural sliding bearing or structural bearing system is installed at an angle, for example.
  • the orientation of the horizontal main sliding surface may differ from a horizontal plane in the narrower sense and may accordingly be inclined. The same applies to the vertically arranged vertical guide surfaces and correspondingly described force effects.
  • the main sliding surface has at least two partial sliding surfaces, each arranged in mutually angled sliding planes, wherein the sliding planes meet at a common intersection line that forms a movement axis of the structural sliding bearing, along which the sliding plate can move. Furthermore, the two sliding planes enclose a first angle.
  • the inventive use of the structural sliding bearing is characterized in that the first angle is selected such that, in the serviceability limit state of the structural sliding bearing, with maximum horizontal force combined with minimal vertical force, no gaping joint occurs in the region of the main sliding surface. In other words, a structural sliding bearing is used without a gaping joint in any of its sliding surfaces.
  • the two mutually inclined partial sliding surfaces of the main sliding surface achieve a functional combination of vertical and horizontal force transfer within the structural sliding bearing. This means that any vertical forces acting as well as horizontal forces acting perpendicular to the axis of movement can now be absorbed by the main sliding surface of the structural sliding bearing.
  • the previously used centrally or laterally mounted rail structures are no longer required, as their functions are fully fulfilled by the main sliding surface. This significantly simplifies the design of the structural sliding bearing and reduces manufacturing costs. The sometimes limited installation space can also be significantly reduced. This applies not only to the omission of the rail structures but also to the corresponding design of the sliding plate.
  • any sections or recesses for engagement with a rail structure are no longer necessary in or on the sliding plate, allowing the dimensions and, in particular, the thickness of the sliding plate to be reduced. Omitting the rail structures also eliminates the potential for dirt and foreign matter to enter this area due to lateral movement.
  • the ratio between the maximum possible vertical force and the horizontal force that the structural sliding bearing can absorb can be optimally adjusted.
  • a gaping joint in the area of the main sliding surface can be avoided when the structural sliding bearing is in use, even with maximum horizontal force combined with the corresponding minimum vertical force.
  • the structural sliding bearing is to be designed for higher horizontal loads
  • the two inclined partial sliding surfaces are designed so steeply relative to the acting horizontal forces that the sliding plate does not lift off the intermediate bearing part when the structural sliding bearing is in use.
  • a sliding material with the lowest possible friction can be used in the area of the main sliding surface to still facilitate the movement of the sliding plate in the direction of the axis of movement.
  • the two mutually inclined partial sliding surfaces enable continuous self-centering of the sliding plate on the intermediate bearing section of the structural sliding bearing relative to the axis of motion. This ensures that the sliding plate is always optimally positioned relative to the intermediate bearing section, and potential edge pressure along the axis of motion is avoided. Bearing play caused by any guide rails is simply eliminated.
  • the main sliding surface has exactly two, most preferably only two, partial sliding surfaces.
  • the two inclined partial sliding surfaces can, for example, form a continuous main sliding surface that is bent only once in the region of the movement axis.
  • the two mutually inclined partial sliding surfaces also intersect along the movement axis.
  • the two inclined partial sliding surfaces can also be formed separately from one another in the respective sliding planes.
  • the structural sliding bearing is preferably a uniaxially guided structural sliding bearing, in which the sliding plate can only move along the axis of movement relative to the intermediate bearing part. This ensures that the structural sliding bearing does not allow any further movement of the sliding plate than that along the axis of movement relative to the intermediate bearing part.
  • the structural sliding bearing is therefore specifically designed for use when horizontal movements in a single direction are to be permitted.
  • the two sliding planes are arranged so that the intersection line runs horizontally.
  • the movement axis of the structural sliding bearing also runs horizontally.
  • the structural sliding bearing is loaded as evenly as possible with regard to force transfer.
  • the sliding plate can move evenly with identical resistance in both directions of the movement axis.
  • the horizontal orientation is to be understood with reference to the movement plane of the structural sliding bearing.
  • the intersection line can also have an orientation other than a horizontal line in the strict sense.
  • the main sliding surface has a permanently lubricated sliding material, preferably with PTFE, UHMWPE, POM and/or PA.
  • the permanently lubricated sliding material in the area of the main sliding surface can significantly reduce the friction between the sliding plate and the intermediate bearing part. Due to the at least two partial sliding surfaces inclined towards one another, a sliding material with a low coefficient of friction can be used here. High horizontal forces can be absorbed simply by a corresponding inclination of the inclined partial sliding surfaces. This facilitates the sliding of the sliding plate along the axis of movement.
  • the sliding material preferably has a coefficient of friction of a maximum of 0.03 for the design value of the pressure in the sliding material.
  • the sliding material comprises at least one lubricated sliding disk, which preferably has at least one lubrication pocket.
  • the prefabricated lubrication pockets can store the lubricant and distribute it evenly across the sliding surface. This creates a particularly low-wear sliding material with a low coefficient of friction. This facilitates the sliding movement of the sliding plate along the movement axis and extends the maintenance intervals of the structural sliding bearing.
  • At least two partial sliding surfaces angled to one another are arranged such that the corresponding sliding planes form the shape of a gable roof.
  • the gable roof is designed such that the intersection line or the axis of movement forms the ridge of the gable roof.
  • the shape of a gable roof has the particular advantage that any accumulation of dirt and foreign matter in the area of the at least two partial sliding surfaces inclined to one another can be largely avoided. This applies particularly in the area of the axis of movement, since this, as the ridge, represents the highest point of the gable roof.
  • At least two partial sliding surfaces angled to each other are arranged such that the corresponding sliding planes form the shape of an upside-down gable roof.
  • the gable roof is designed such that the intersection line or the axis of movement forms the ridge of the gable roof. Due to the upside-down roof shape, it is possible to install the sliding plate in The most heavily loaded center can be made stronger than the edges, without requiring additional vertical space. This allows for further space savings despite increased loads.
  • At least two partial sliding surfaces angled to one another can be designed symmetrically to one another with respect to a plane of symmetry running through the intersection line in the vertical direction.
  • the symmetrical arrangement of the at least two partial sliding surfaces inclined to one another achieves improved self-centering of the sliding plate on the intermediate bearing part.
  • the structural sliding bearing has a simple design and is therefore cost-effective to manufacture.
  • the vertical direction is to be understood with reference to the plane of movement of the structural sliding bearing.
  • the vertical direction can also have an orientation other than a vertical in the narrower sense.
  • At least two partial sliding surfaces of the main sliding surface are of different sizes.
  • This configuration is particularly advantageous when horizontal forces of different magnitudes act on the structural sliding bearing from different directions.
  • the structural sliding bearing according to the invention can be specifically designed to absorb greater forces acting from a specific horizontal direction transverse to the axis of movement than from an opposite direction. This can prevent the formation of a gaping joint or the lifting of the sliding plate even under uneven force application.
  • the two opening angles between the plane of symmetry and the respective inclined partial sliding surface could also be of different sizes.
  • At least one sliding plane is inclined downwards by a second angle of 6 degrees relative to the horizontal.
  • the respective inclined partial sliding surface can absorb correspondingly higher horizontal forces transverse to the axis of movement.
  • the horizontal is to be understood with reference to the plane of movement of the structural sliding bearing.
  • the horizontal can therefore also have an orientation other than a horizontal plane in the narrower sense.
  • the second angle corresponds at least to the permissible friction to be assumed for the design.
  • the first angle can be 168 degrees.
  • the respective inclined partial sliding surface can absorb correspondingly higher horizontal forces perpendicular to the movement axis.
  • the sliding plate is made up of multiple parts, and the distance between the corresponding sliding plate parts is adjustable.
  • This arrangement of the structural sliding bearing according to the invention provides for simple height adjustment. In particular, it makes it possible to adjust the distance between the sliding plate or the sliding plate parts and the lower bearing part. The distance between the two structural parts is thus also changed accordingly.
  • the sliding plate is advantageously divided into two sliding plate parts. In this simplest case, one sliding plate part is arranged along each of the two mutually inclined partial sliding surfaces. If the two sliding plate parts are now pushed synchronously toward or apart from one another transversely to the movement axis along the corresponding sliding planes, the horizontal distance between both sliding plate parts and the lower bearing part of the structural sliding bearing also changes. If, however, only one of the two sliding plate parts is moved in this way, or if both sliding plate parts are moved non-synchronously, the position of the second structural part is tilted relative to the first structural part.
  • the structural sliding bearing is designed as a pot bearing, with the intermediate bearing section featuring a pot cover and the lower bearing section featuring a pot with an elastomer cushion.
  • the pot cover and the underlying elastomer cushion effectively transfer vertically acting forces from the sliding plate to the pot. At the same time, rotational movement between the sliding plate and the pot is also possible.
  • the structural sliding bearing is designed as a spherical bearing, in which the intermediate bearing part has a spherical cap.
  • the spherical cap has a convex section and the bearing base a corresponding concave section, with the convex section of the spherical cap being arranged to slide in the concave section of the bearing base.
  • vertically acting forces are effectively transferred from the sliding plate to the bearing base by means of the spherical cap.
  • rotations between the sliding plate and the bearing base are enabled. In combination with the design of the at least two mutually inclined partial sliding surfaces in the form of an upside-down gable roof, this also ensures that the eccentricities from acting horizontal forces are significantly reduced.
  • the sliding plate is stronger at the most highly stressed center than at the edge. This allows the entire sliding plate to be made thinner and thus produced more economically.
  • the concave section of the bearing base preferably has a recess at a lower pole so that in the area of the recess the convex section of the calotte does not come into contact with the concave section of the bearing base.
  • the lower pole is understood to be the lowest point of the concave section of the bearing base.
  • the recess at the lower pole increases the radius of gyration and, while the outer diameter remains the same, the pressure is increased by reducing the pressure area. This reduces friction and thus the torsional resistance, i.e. the acting moment. This reduces the risk of gaping. Accordingly, the opposing pressure from the acting vertical load increases compared to the pressure from the lifting horizontal force. This ratio can be controlled by the diameter of the recess.
  • the structural sliding bearing can be individually adjusted and designed in combination with at least two mutually inclined partial sliding surfaces of the main sliding surface.
  • the recess is circular, centered on the lower pole. This arrangement ensures a uniform influence on the absorbable vertical and horizontal forces from different directions of action. Likewise, any acting forces are evenly transferred from the calotte to the lower bearing section. An elliptical recess with the corresponding displacement for uniform force transfer would also be conceivable.
  • a sliding material preferably a polymer sliding disk
  • the sliding material or the polymer sliding disk can reduce friction in the area of the secondary sliding surface of the spherical bearing.
  • the sliding material is generally in contact with the convex section of the spherical cap.
  • the recess in the sliding material prevents such contact with the spherical cap in this area, achieving the advantages already discussed.
  • the recess in the sliding material is also easy to manufacture.
  • an annular polymer sliding disk can be used, which is attached to the concave section of the bearing base in the area of the secondary sliding surface.
  • the structural sliding bearing further comprises at least one stop between the sliding plate and the bearing base.
  • the stop can be designed in any form, to limit movement of the sliding plate relative to the bearing base to a predetermined extent. This allows the structural sliding bearing to be converted into a fixed bearing. Such a bearing exhibits no play transverse to the mutually inclined sliding surfaces. Furthermore, it exhibits low torsional resistance.
  • the structural sliding bearing When used according to the invention, the structural sliding bearing is designed as simply as possible and can operate maintenance-free and reliably for a long time under increased forces. This reduces the costs and effort involved in manufacturing and operating the structural sliding bearing.

  • the structural sliding bearing 210 is designed as a uniaxially guided spherical bearing and, for force transfer, has a bearing base 212 that can be connected to a first structural part, a spherical bearing intermediate part 214, and a sliding plate 216 that can be connected to a second structural part.
