Description

[0001] The present invention relates to a structural support system with at least two sliding tilt bearings for connecting at least two structural components.

[0002] Structural sliding bearings typically comprise a bearing base that can be connected to the first structural element, a sliding plate that can be connected to a second structural element, and an intermediate bearing section located between the bearing base 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 during operation. Several such structural sliding bearings together form a structural support system of the same type, with a corresponding number of connection points between the respective structural elements.

[0003] Such structural support systems for connecting various structural components are, in principle, sufficiently known from the prior art. For example, documents CN 108 532 451 A, DE 35 17 895 A1, DE 101 28 362 A1 and DE 40 39 523 A1 disclose structural sliding bearings or structural support systems as known from the prior art.

[0004] Structural bearings generally transfer vertical and horizontal loads and allow for rotations and relative displacements where necessary. Structural sliding bearings are a specific type of structural bearing used for the defined and, ideally, stress-free support of various structures, such as bridges (especially in road and rail transport), girders, and buildings of any kind or parts thereof. They enable relative movement between two structural components, which can arise from the use of the structure or from external influences such as wind or earthquakes. The use of such structural bearings or corresponding structural support systems can thus prevent damage to the structures in question.

[0005] According to DIN EN 1337, various designs and operating principles of structural bearings are known. Depending on their design and operating principle, these bearings have different structures and a different number of degrees of freedom. Structural bearings can be designed as either fully fixed bearings or fully or unilaterally displaceable bearings. According to DIN 4141-13, there are also solutions in which a guided bearing is converted into a fixed bearing by means of locking mechanisms. The present invention relates in particular to uniaxially guided or unilaterally displaceable structural sliding bearings, in which a displacement movement of the sliding plate is thus enabled along a specific axial direction of the main sliding surface. Bearings subsequently converted into fixed bearings are also relevant to the present invention. Such uniaxially guided structural sliding bearings can, for example, be implemented as pot bearings or spherical bearings.Both types of structural sliding bearings are shown schematically in the . Fig. 1 and 2 The images are shown and are briefly explained below.

[0006] Fig. 1 Figure 1 shows a uniaxially guided structural sliding bearing in the form of a pot bearing 10, also called a pot sliding bearing, as known from the prior art. As can be seen in the figure, the pot sliding bearing 10 has a pot 12 as the bearing base, which can be connected to a first part of the structure. The pot 12 includes a machined recess 14 for receiving an elastomer cushion 16, an internal seal 18, and a pot cover 20, which represents the intermediate bearing part of the pot sliding bearing 10. The pot cover 20 closes the opening of the pot 12 and rests flush on the elastomer cushion 16 arranged below it. Above the pot cover 20 is the sliding plate 22, which can be connected to a second structural part. Both the pot lid 20 and the sliding plate 22 are horizontally aligned, so that a horizontal main sliding surface 24 of the pot sliding bearing 10 extends between these two components.For this purpose, 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 allows the sliding plate 22 to slide along the main sliding surface 24 with as little resistance as possible.

[0007] The cup bearing 10 can thus absorb vertically acting forces or loads via the sliding plate 22, the horizontal main sliding surface 24, the cup lid 20, and the elastomer cushion 16, and transfer them to the underlying cup 12. Simultaneously, the elastomer cushion 16 allows for any rotational movement of the cup bearing 10. This occurs through localized yielding of the elastomer cushion 16 in the area of ​​force exerted by the cup lid 20. The inner seal 18 is arranged such that it prevents the elastomer cushion 16 from being forced out through the gap between the cup wall and the cup lid 20 as soon as a pressure load is applied to the elastomer cushion 16. Furthermore, an outer seal can be arranged between the cup lid 20 and the cup 12 to keep moisture and dirt away from the corresponding gap.

[0008] Furthermore, the cup bearing 10 has a central guide rail 28 to enable the uniaxial displacement of the sliding plate 22. The central guide rail 28 is located above the cup lid 20 in the area of ​​the main sliding surface 24 and engages with a corresponding groove in the sliding plate 22. Thus, the guide rail 28 defines the axis of movement of the cup bearing 10 by absorbing all horizontal forces perpendicular 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. Therefore, horizontally acting forces act perpendicularly from both sides on the central guide rail 28 and can thus be effectively absorbed. The guide rail 28 also has a sliding material 30 along both vertical sliding surfaces, which is initially lubricated.The friction between the guide rail 28 and the sliding plate 22 is thus reduced, facilitating movement of the sliding plate 22 along its axis of motion. Therefore, when horizontal forces act on the cup bearing 10, running parallel to the guide rail 28, the sliding plate 22 shifts relative to the underlying cup lid 20. These force components are thus not absorbed and transmitted by the cup bearing 10. Corresponding movements of the structural components can therefore be compensated.

[0009] The situation is different with horizontal forces acting perpendicular to the guide rail 28. The sliding plate 22 cannot accommodate any horizontal movements perpendicular to the guide rail 28. Therefore, such forces are absorbed and transmitted by the guide rail 28 or the cup bearing 10. Corresponding movements of the structural components cannot be compensated for.

[0010] Besides the in Fig. 1 In addition to the illustrated embodiment, there are also solutions where the guide rail is formed on the sliding plate and the groove is formed on the pot lid. The previously discussed fundamental functional principle regarding the degrees of freedom and force transmission between the pot lid and the sliding plate applies accordingly.

[0011] In Fig. 2 A uniaxially guided structural sliding bearing in the form of a spherical bearing 110, as known from the prior art, is shown. The spherical bearing 110 has a bearing base 112, which can be connected to a first part of the structure. Furthermore, 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. In the area of ​​the secondary sliding surface 116, a sliding material 118 is arranged to enable the movement of the spherical cap 114 within the concave section of the bearing base 112 with as little resistance as possible.Above the spherical dome rests the sliding plate 120, which can be connected to a second part of the structure. Thus, the horizontal main sliding surface 122, or primary sliding surface of the spherical bearing 110, is located between the spherical dome 114 and the sliding plate 120. A sliding material 124 is arranged on the spherical dome 114 in the area of ​​the main sliding surface 122 to reduce friction between the spherical dome 114 and the sliding plate 120. This also enables the sliding plate 24 to slide along the main sliding surface 122 with minimal resistance.

[0012] 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 bearing 114, and transfer them to the bearing base 112. Simultaneously, the convex curvature of the spherical bearing 114 and the receiving concave section of the bearing base 112 allow corresponding rotations of the spherical bearing 114 and the spherical bearing 114, respectively. This occurs through the sliding of the spherical bearing 114 along the secondary sliding surface 116.

[0013] In this embodiment, the uniaxial guidance of the spherical bearing 114 is achieved by two horizontal lateral guide rails 126. These are arranged laterally on the bearing base 112 next to the main sliding surface 122, in order to engage with the sliding plate 120. Thus, here too, any horizontal forces transverse to the two lateral guide rails 126 are absorbed, thereby defining the axis of movement of the spherical bearing 114. As with the cup bearing 10, the sliding surfaces between the two lateral guide rails 126 and the sliding plate 120 are each designed vertically along the axis of movement. Due to the perpendicular application of the horizontal forces to the sliding surfaces of the two guide rails 126, even higher force applications can be effectively absorbed. Likewise, 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, thereby simplifying the movement of the sliding plate 120 along the axis of movement.

[0014] As soon as horizontal forces parallel to the two lateral guide rails 126 act on the spherical bearing 110, the sliding plate 120 shifts relative to the underlying spherical bearing 114. These horizontal forces are therefore not absorbed and transmitted by the spherical bearing 110. Corresponding movements of the structural components can thus be compensated.

[0015] The opposite occurs with horizontal forces acting perpendicular to the two lateral guide rails 126. The sliding plate 120 cannot perform corresponding horizontal movements in this direction. Therefore, such horizontally directed forces are absorbed by the two lateral guide rails 126 or transferred directly from the sliding plate 120 to the bearing base 112. Horizontal forces acting perpendicular to the two lateral guide rails 126 are thus absorbed by the spherical bearing 110. Corresponding movements of the structural components cannot therefore be compensated.

[0016] In the described types of uniaxially guided structural sliding bearings, there is a functional separation between vertical and horizontal force transmission. While vertical loads are absorbed by the respective main sliding surface of the bearing intermediate section, horizontal forces acting perpendicular to the axis of movement are transferred to the corresponding guide rails. As specified in section 6.8 of the standard DIN EN 1337-2:2004 for bearings in civil engineering, the known structural sliding bearings are designed such that no gap occurs in the area of ​​the horizontal main sliding surface during operation. In this disclosure, a gap is understood to mean a partial lifting within the sliding surface. Thus, the overall gap is decisive for the load-bearing capacity of the structural sliding bearing.

[0017] According to the standard DIN EN 1990:2010-12 for the fundamentals of structural design, the serviceability limit state extends to and including the serviceability limit state. If this limit state is exceeded, the specified conditions for the serviceability of a structure or a component are no longer met. Thus, limit states that affect the function of the structure or one of its parts under normal service conditions, the well-being of the users, or the appearance of the building are also classified as serviceability limit states.

[0018] In the case of special structural sliding bearings or structural bearing systems designed for extreme events such as an earthquake, the serviceability limit may still be reached when such an event occurs. This applies particularly to the state after the activation of any emergency or buffer functions, which are only used in extreme cases. For example, during the serviceability limit, a controlled lifting of the sliding plate from the intermediate bearing section is provided.

[0019] Although, for the sake of simplicity, all orientations of surfaces, axes, and forces are described here as horizontal or vertical, they are not limited to a horizontal or vertical plane or direction in the strict sense. In this disclosure, such orientation specifications refer only to the plane of motion of the structural sliding bearing or the structural support system. This applies in particular if the structural sliding bearing or the structural support system is installed at an angle, for example. In this case, the orientation of the main horizontal sliding surface may differ from a horizontal plane in the strict sense and may also be inclined. The same applies to the vertically arranged guide surfaces perpendicular to it and the correspondingly described force effects.

[0020] Despite this proven principle of force transmission, it has been observed that, especially during prolonged use of such structural sliding bearings, significant amounts of dust, dirt, or other foreign matter can accumulate in the area of ​​the rail structures. If regular maintenance of the structural sliding bearings is not carried out, this can lead to increased wear of the sliding material or impairment of the sliding behavior of the structural sliding bearing. This is primarily due to the fact that a certain amount of play exists between the respective components of such rail structures, which is fundamentally unavoidable – particularly in the area of ​​the vertical sliding surfaces between the guide rail and the sliding plate. Thus, a gap is normally present in the area of ​​the vertical guide surfaces during the structural sliding bearing's service life. This play, or rather...This gap also leads to edge pressures in the area of ​​the guide surfaces. The result is uneven force transmission within the structural sliding bearing, which can lead to increased and uneven wear of the sliding material. Furthermore, due to the clearance, the guide surfaces of the rail structure can only be lubricated initially; a continuous supply of lubricant is not guaranteed. In addition, a sliding material capable of withstanding high local pressures must be used. Ultimately, this results in the use of sliding materials that exhibit relatively poor sliding properties due to relatively high coefficients of friction and relatively high wear.

[0021] Furthermore, uniaxially guided structural plain bearings with a central guide rail are of limited use when absorbing very high forces. Conversely, the use of two lateral guide rails restricts the bearing's rotation around the vertical axis. Ultimately, the structural plain bearings described represent complex structures that require a correspondingly high amount of space and incur significant manufacturing and maintenance costs. Structural support systems incorporating such plain bearings suffer from the same disadvantages.

[0022] The object of the present invention is therefore to provide an improved structural support system that is as simple in design as possible and operates as maintenance-free and reliably as possible for as long as possible, even under increased force, so that costs and effort in manufacturing and during use can be reduced.

[0023] The problem described above is solved according to the invention with a building support system according to claim 1. Advantageous further developments of the invention are set out in dependent claims 2 to 17.

[0024] The structural support system according to the invention comprises at least two sliding bearings for connecting at least two structural components. Each sliding bearing has a bearing base that can be connected to a first structural component, a sliding plate that can be connected to a second structural component, and a bearing intermediate part arranged between the bearing base and the sliding plate. At least one flat main sliding surface of the sliding bearing is arranged between the bearing intermediate part and the sliding plate. Furthermore, the structural support system is characterized in that the two sliding bearings form a bearing pair, in which the main sliding surface of the first sliding bearing is arranged in a first sliding plane angled to the horizontal, and the main sliding surface of the second sliding bearing is arranged in a second sliding plane angled to the horizontal.The sliding planes meet at a common intersection line, which forms an axis of movement for the bearing pair, along which the sliding plates can move.

[0025] The two mutually inclined main sliding surfaces of the first and second sliding bearings achieve a functional combination of vertical and horizontal force transmission within the bearing pair and thus also within the entire structural support system. This allows all vertical as well as horizontal forces acting perpendicular to the axis of movement to be absorbed by the main sliding surfaces of the first and second sliding bearings. While the first sliding bearing can only absorb horizontal forces from a specific direction perpendicular to the axis of movement, horizontal forces from the opposite direction are absorbed by the second sliding bearing. The two sliding bearings thus complement each other to form a structural support system.

[0026] Therefore, any centrally or laterally mounted rail structures are no longer necessary, as the horizontal force transmission is fully achieved by the inclined main sliding surfaces of both sliding bearings. This significantly simplifies the design of the individual sliding bearings and, consequently, the corresponding structural support system. Manufacturing costs can be considerably reduced. The often limited available installation space can also be reduced. This applies not only to the rail structures but also to the complementary sliding plates. Any sections or recesses for engaging a guide rail are no longer required in or on the sliding plate. The dimensions, and especially the thickness, of the sliding plate can thus be significantly reduced. Furthermore, by eliminating the rail structures, the potential ingress of dirt and foreign matter into this area due to lateral play is also eliminated.Ultimately, permanently lubricated sliding materials with significantly less friction and wear can also be used for the guide surfaces here.

[0027] Furthermore, the two inclined main sliding surfaces ensure continuous self-centering of the system, consisting of the two sliding plates and the connected structure, relative to the axis of movement defined by the two sliding bearings. This system is therefore optimally positioned at all times relative to the intermediate bearing sections of the two sliding bearings, and potential edge pressures along the axis of movement can be avoided. Additionally, bearing play is eliminated due to the use of guide rails. Such an arrangement is therefore particularly advantageous in the construction of bridges for high-speed rail lines, where lateral misalignment must be absolutely avoided.

[0028] The two separate sliding plates of the two sliding bearings also provide simple height adjustment. In particular, it allows the distance between the two sliding plates and the respective bearing bases to be adjusted. This, in turn, changes the distance between the two structural components. If the two sliding plates are moved synchronously towards or away from each other along their respective sliding planes, perpendicular to the axis of movement, the horizontal distance between both sliding plates and the respective bearing bases of the two sliding bearings also changes. However, if, for example, only one of the two sliding plates is moved in this way, or if both sliding plates are moved asynchronously, the second structural component will tilt relative to the first. Alternatively, the two sliding plates can also be manufactured as a single piece.

[0029] As explained above, the horizontal is to be understood in relation to the plane of movement of the building's support system. Therefore, the horizontal can also have a different orientation than a horizontal plane in the strict sense.

[0030] Advantageously, at least two of the sliding bearings are designed as tilting bearings. For example, spherical bearings, which offer the advantages described above, would be suitable. Alternatively, at least two of the sliding bearings can be designed as elastomer bearings. In addition to their sliding properties, these also exhibit deformation properties in the intermediate bearing section, which allows for particularly effective compensation of rotations and point loads.

[0031] Advantageously, the first and second sliding planes enclose a first angle, which can be chosen such that no gaping joint forms in the area of ​​the main sliding surfaces during the service life of the structural support system. The ratio between the maximum permissible vertical force and horizontal force of the structural support system can be adjusted by the inclination of the two main sliding surfaces relative to each other, or by choosing the first angle. This can be achieved without having to adjust the dimensions of the individual main sliding surfaces. Thus, by appropriately choosing the inclination of the two main sliding surfaces relative to each other, a gaping joint in the area of ​​the main sliding surfaces can be avoided during the service life of the structural support system, even with maximum horizontal force combined with a correspondingly minimum vertical force.For example, if the structural support system is designed for higher horizontal loads, the two inclined main sliding surfaces are designed with such a steep incline relative to the respective horizontal forces that a gaping joint or even lifting of the sliding plates from the respective intermediate bearing components does not occur during the structural support system's operational state. At the same time, a sliding material with the lowest possible friction can be used in the area of ​​the main sliding surfaces to still facilitate the movement of the sliding plates in the direction of the axis of movement as much as possible.

[0032] Preferably, the bearing pair is a uniaxially guided bearing pair in which the sliding plates can only move along the axis of movement relative to the intermediate bearing parts. This ensures that the structural support system does not permit any movement of the sliding plates other than along the axis of movement relative to the intermediate bearing parts. The structural support system can therefore be used specifically when horizontal movements in a single direction are required.

[0033] Furthermore, the first and second sliding planes are arranged so that the line of intersection runs horizontally. Thus, the axis of movement of the bearing pair also runs horizontally. With this configuration, the bearing pair is subjected to a uniform load with respect to force transmission. Moreover, the sliding plates can move uniformly with identical resistance in both directions along the axis of movement. As explained above, the horizontal orientation refers to the plane of movement of the structural support system. Therefore, the line of intersection can also have an orientation other than a strictly horizontal line.

[0034] Advantageously, the first angle can be chosen such that no gaping joint forms in the area of ​​the main sliding surfaces during the ultimate limit state of the structural support system. If the loads on the structural support system are further increased starting from the serviceability limit state, the ultimate limit state occurs. According to the standard DIN EN 1990:2010-12 for the basis of structural design, this state is associated with collapse or other forms of structural failure. Therefore, those limit states that affect the safety of persons and / or the safety of the structure are also classified as ultimate limit states. Thus, even in this state, it is ensured that no gaping joint forms in the area of ​​the main sliding surfaces and that the sliding plate does not lift off the intermediate bearing section.

[0035] Advantageously, at least one main sliding surface has a permanently lubricated sliding material, preferably PTFE, UHMWPE, POM, and / or PA. The permanently lubricated sliding material in the area of ​​the main sliding surface significantly reduces friction between the sliding plate and the intermediate bearing element. Due to the inclined main sliding surfaces, a sliding material with a low coefficient of friction can be used. High horizontal forces can be absorbed simply by appropriately inclined the main sliding surfaces. This facilitates the sliding of the sliding plate along the axis of motion. Preferably, the sliding material has a coefficient of friction of no more than 0.03 for the design pressure in the sliding material.

[0036] Preferably, the sliding material comprises at least one lubricated sliding disc, which preferably has at least one lubrication pocket. The pre-formed lubrication pockets can store the lubricant and distribute it evenly over the sliding surface. This results in a particularly wear-resistant sliding material with a low coefficient of friction. Consequently, the sliding motion of the corresponding sliding plate along the axis of movement is facilitated, and the maintenance intervals of the structural support system are extended.

[0037] Furthermore, the two main sliding surfaces of the two sliding bearings, angled relative to each other, are arranged such that the corresponding sliding planes form the shape of a gable roof. The gable roof is designed such that the line of intersection, or axis of movement, forms the ridge of the gable roof. The gable roof shape has the particular advantage that any accumulation of dirt and foreign matter in the area of ​​the main sliding surfaces can be largely avoided. This is especially true in the area of ​​the axis of movement if the first and second sliding bearings are installed in close proximity, since the axis of movement, as the ridge, represents the highest point of the gable roof.

[0038] Advantageously, the two main sliding surfaces of the two sliding bearings, angled relative to each other, are arranged such that the corresponding sliding planes form the shape of an inverted gable roof. Here, too, the gable roof is designed so that the line of intersection, or axis of movement, forms the ridge of the gable roof. Due to the inverted roof shape, it is possible to make each sliding plate thicker at the end near the axis of movement without requiring additional installation space in the vertical direction. Thus, despite increased loads, installation space can be saved once again.

[0039] Advantageously, the two main sliding surfaces of the two sliding bearings, angled relative to each other, are designed symmetrically with respect to a plane of symmetry extending vertically through the line of intersection. The arrangement according to the invention enables improved self-centering of the system consisting of both sliding plates and the connected structure relative to the axis of movement defined by the two sliding bearings. Furthermore, it is particularly advantageous when forces are applied evenly from all sides if the conditions for the displacement of each sliding plate in both directions along the axis of movement are as similar as possible. In addition, the structure support system has a simple design and is therefore cost-effective to manufacture. As explained above, the vertical direction refers to the plane of movement of the structure support system.Thus, the vertical direction can also have a different orientation than a vertical in the narrower sense.

[0040] Preferably, the two main sliding surfaces of the two sliding bearings, angled relative to each other, are of different sizes. This design is particularly advantageous when different magnitudes of horizontal forces act on the structural support system from different directions. In this way, the structural support system according to the invention can be specifically designed to absorb greater forces acting from a particular horizontal direction perpendicular to the axis of movement than from an opposite direction. This ensures that the formation of a gaping joint or even the lifting of the sliding plate can be prevented, even under uneven force application.

[0041] Further developing the design, the first and / or the second sliding bearing features a stop device, preferably lateral, that limits the movement of the sliding plate relative to the bearing base. This prevents the second component from rotating relative to the first. Preferably, the stop device is designed such that a moment acting on the second component is supported about an axis parallel to the axis of movement. The stop device can be designed, for example, as a single-piece stop or in multiple parts. In one example, the stop device is attached to the bearing base.

[0042] Advantageously, the stop device is arranged on a side of the respective sliding bearing that faces or is inclined away from the axis of movement. This arrangement allows for the targeted absorption of moments acting on the second structural component about an axis parallel to the axis of movement. Preferably, the stop device is arranged on the side of the sliding bearing that is higher in the vertical direction. This has the advantage that, for small or negligible moments, primarily the vertical force component of the bearing's own weight relative to the operational load acts on the bearing. The stop device itself is thus completely free of any force. This significantly reduces wear on the stop device and increases its service life.

[0043] Advantageously, the stop device includes an adjustment mechanism for setting its position. This adjustment mechanism allows the stop device to be optimally and precisely positioned relative to the individual components of the sliding bearing, depending on the situation. The adjustment mechanism can be implemented, for example, via a screw connection. Alternatively, the adjustment mechanism could incorporate an electric motor for particularly precise and / or automatic position adjustment.

[0044] Preferably, the stop device includes a sliding mechanism that guides the sliding plate in a direction parallel to the axis of movement. Despite its function of restricting movement towards and away from the axis of movement, the sliding mechanism allows the sliding plate to move with minimal friction relative to the bearing base along the axis of movement. In one embodiment, the sliding mechanism is designed as a sliding strip.

[0045] Advantageously, the structural support system comprises at least two pairs of bearings and an axis. The pairs of bearings are arranged sequentially along the axis, with the mutually angled main sliding surfaces positioned such that the corresponding sliding planes of the bearing pairs alternately form the shape of a gable roof and the shape of an inverted gable roof along the axis. The axis can preferably be straight. A curved axis would also be conceivable, as is the case, for example, with a roadway, a railway track, or a pipeline. The alternating arrangement of the main contact surfaces allows for the targeted absorption of potential torsional moments of the structure.

[0046] Preferably, the structural support system comprises at least two pairs of bearings and an axis. The pairs of bearings are arranged sequentially along the axis, with the mutually angled main sliding surfaces arranged such that the corresponding sliding planes of the bearing pairs alternately form the shape of a gable roof and the shape of an inverted gable roof at every second pair of bearings along the axis. The axis can preferably be straight. A curved axis would also be conceivable, as can be the case, for example, with a roadway, a railway track, or a pipeline. This principle can be particularly applicable when several simply supported beams are mounted sequentially along the axis by the structural support system. In this case, one end of each simply supported beam is held by a pair of bearings.At the connection points between the simply supported beams, a consistent arrangement of the main sliding surfaces of both bearing pairs is used. This minimizes any vertical displacement in the joint between the two simply supported beams in the event of lateral expansion in the structure. Preferably, the inclination of the main sliding surfaces is also identical for two consecutive sliding bearings along the axis in the region of such a connection point. This further reduces the risk of vertical displacement.

[0047] The structural support system according to the invention is therefore designed to be as simple as possible while simultaneously operating reliably and maintenance-free for extended periods under increased loads. This reduces the costs and effort involved in the manufacture and operation of the structural support system.

[0049] Identical components in the different embodiments are identified with the same reference numerals.

[0050] In the Fig. 3 bis 7 The schematic structure of a structural sliding bearing 210 is shown according to an example that is not part of the present invention. The structural sliding bearing 210 is designed in the form of a uniaxially guided spherical bearing and comprises, for force transmission, a bearing base 212 which can be connected to a first structural component, a spherical bearing as an intermediate bearing component 214, and a sliding plate 216 which can be connected to a second structural component.

[0051] The bearing base 212 has a concave section 218 in which the spherical cap with its convex section 220 is slidably received. The secondary sliding surface 222 of the structural sliding bearing 210 is thus located between the convex section 220 of the spherical cap and the concave section 218 of the bearing base 212. A sliding material 224 in the form of a polymer sliding disc is arranged on the concave section 218 of the bearing base 212 in the region of the secondary sliding surface 222. This reduces the friction between the convex section 220 of the spherical cap and the concave section 218 of the bearing base 212. The movement of the spherical cap relative to the bearing base 212 is thus facilitated, and the structural sliding bearing 210 allows rotation about the vertical and horizontal axes.

[0052] As shown in particular in the exploded view of the Fig. 4 As can be seen from the top view, the sliding plate 216 rests slidably on the spherical cap in order to be connected to the second structural element from above. Thus, the main sliding surface 226 of the structural sliding bearing 210 is arranged between the spherical cap and the sliding plate 216. Fig. 5 as well as the cross-sections of the Fig. 6 und 7 As shown, the main sliding surface 226 has two mutually inclined partial sliding surfaces 228A and 228B. Both partial sliding surfaces 228A and 228B are arranged in two mutually angled sliding planes 230A and 230B, which meet at a common horizontal intersection line S. The intersection line S forms the axis of movement A of the structural sliding bearing 210, along which the sliding plate 216 can move. This allows for corresponding displacements of the first structural section relative to the second structural section.

[0053] The two mutually inclined partial sliding surfaces 228A and 228B are arranged such that the corresponding sliding planes 230A and 230B form the shape of a gable roof. Alternatively, the shape of an inverted gable roof (not shown) would also be conceivable, with the axis of movement A forming the ridge of the gable roof. Furthermore, the two mutually inclined partial sliding surfaces 228A and 228B are of equal size and symmetrical to each other with respect to a plane of symmetry E extending vertically through the line of intersection S. Alternatively, the two mutually inclined partial sliding surfaces 228A and 228B could also be of different sizes (not shown).

[0054] Furthermore, the main sliding surface 226 features a sliding material 232 to reduce friction between the dome and the sliding plate 216. In this case, each of the two mutually inclined partial sliding surfaces 228A and 228B has a permanently lubricated polymer sliding disc, each mounted in a recess 234 on the dome. The polymer sliding disc is made of PTFE, UHMWPE, POM, and / or PA and has pre-formed lubrication pockets in which the lubricant can be stored and distributed evenly over the entire contact surface. As a result, the sliding material 232 has a very low coefficient of friction and is particularly wear-resistant. In the present embodiment, the coefficient of friction is a maximum of 0.03.

[0055] The special arrangement of the main sliding surface 226 and the two mutually inclined partial sliding surfaces 228A and 228B enables a combined function for vertical and horizontal force transmission. Thus, the structural sliding bearing 210 can, on the one hand, absorb vertically acting forces via the two mutually inclined partial sliding surfaces 228A and 228B and transfer them from the second structural element to the first. In this embodiment, vertically acting forces are therefore introduced from the second structural element to the first structural element via the sliding plate 216, the spherical cap, and the bearing base 212. On the other hand, the two mutually inclined partial sliding surfaces 228A and 228B can also absorb horizontal forces directed perpendicular to the axis of movement A and transfer them accordingly between the two structural elements.

[0056] The ratio of permissible vertical loads and horizontal forces perpendicular to the axis of movement A can be adjusted by the inclination of the two partial sliding surfaces 228A and 228B, or the corresponding two sliding planes 230A and 230B. Thus, both sliding planes 230A and 230B enclose a first angle α, which is selected such that no gap occurs in the area of ​​the main sliding surface 226 during the service life of the structural sliding bearing 210. The first angle α of the structural sliding bearing 210 is even selected such that no gap occurs in the area of ​​the main sliding surface 226 even during the ultimate limit state of the structural sliding bearing 210. The Fig. 3 bis 7 The illustrated structural sliding bearing 210 has a first angle of 168 degrees. However, if the structural sliding bearing 210 is to be designed for very high horizontal forces, a more acute first angle α can also be used.

[0057] Alternatively or additionally, the inclination of the two sliding planes 230A and 230B can also be specified via their angle of intersection with the horizontal H. Thus, both sliding planes 230A and 230B are inclined downwards by a second angle β relative to the horizontal H. In the present example, both sliding planes 230A and 230B of the structural sliding bearing 210 have the same second angle β, which is 6 degrees. However, in the case of very high horizontal forces, a particularly steep angle can also be chosen. It would also be possible for the sliding plane 230A to have a different second angle β than the sliding plane 230B in order to selectively absorb forces of varying magnitudes from different directions (not shown).

[0058] In the Fig. 8 A sequence of two schematic cross-sectional views of a structural sliding bearing 310, according to an example that is not part of the present invention, is shown, illustrating the height adjustment of the structural sliding bearing. The structural sliding bearing 310 essentially corresponds to the structural sliding bearing 210. The identical components will not be discussed further below.

[0059] The structural sliding bearing 310 differs from the structural sliding bearing 210 in that the sliding plate 316 is multi-part and the distance between the corresponding sliding plate parts 316A and 316B is adjustable. In this example, the sliding plate 316 is simply divided into two halves, so that the sliding plate 316 is formed by two identically sized sliding plate parts 316A and 316B. The two sliding plate parts 316A and 316B are each arranged along one of the two mutually inclined partial sliding surfaces 228A and 228B in order to enable a horizontal connection of the second structural part.

[0060] In the left of the two cross-sections of the Fig. 8 The initial state of the structural sliding bearing 310 before height adjustment is shown. The two sliding plate parts 316A and 316B are arranged separated from each other by a horizontal first distance d1. Both sliding plate parts 316A and 316B have the same horizontal distance to the axis of movement A. With this arrangement, the structural sliding bearing 310 has a first overall height G1.

[0061] If the two sliding plate parts 316A and 316B are now moved synchronously towards or away from each other along their respective partial sliding surfaces 228A and 228B, the first overall height G1 of the structural sliding bearing is changed by a height difference ΔH. This enables simple height adjustment of the structural sliding bearing 310. In the right cross-section of the Fig. 8 For example, the final state of the structural sliding bearing 310 is shown after the two sliding plate parts 316A and 316B have been moved towards each other. As can be seen in the illustration, the horizontal first distance d1 between the two sliding plate parts 316A and 316B has decreased to the horizontal second distance d2. Nevertheless, both sliding plate parts 316A and 316B still have the same horizontal distance to the axis of movement A. Thus, the first overall height G1 is increased by the height difference ΔH to a second overall height G2. If, on the other hand, the two sliding plate parts 316A and 316B are moved apart, the first overall height G1 is reduced accordingly.

[0062] The Fig. 9 Figure 1 shows a schematic exploded view of an exemplary structural sliding bearing 410, which is not part of the present invention. The structural sliding bearing 410 is essentially identical to the structural sliding bearing 210. The identical components will not be discussed further below.

[0063] However, the structural sliding bearing 410 differs from the structural sliding bearing 210 in that the concave section 418 of the bearing base 412 has a recess 436 at a lower pole P, so that in the area of ​​the recess 436 the convex section 220 of the spherical bearing does not come into contact with the concave section 418 of the bearing base 412. In the present example, this recess 436 is formed in the polymer sliding disc of the sliding material 424 in the area of ​​the secondary sliding surface 422. The recess 436 has a circular shape and is centered on the lower pole P.

[0064] The recess 436 at the lower pole P increases the radius of gyration. Consequently, the counteracting pressure from the applied vertical load increases compared to the pressure from the lifting horizontal force. This ratio can be controlled by the diameter D of the recess 436. Thus, the structural sliding bearing 410 can absorb even greater forces. Furthermore, the structural sliding bearing 410 with the recess 436 offers an additional adjustment option for adapting the ratio between absorbable vertical and horizontal forces. The inclination of the two mutually inclined partial sliding surfaces 228A and 228B can be matched to the diameter D of the recess 436 to optimally design the structural sliding bearing 410 for a wide variety of force applications.

[0065] In the Fig. 10 A schematic exploded view of an exemplary structural sliding bearing 510 is shown, which is not part of the present invention. The structural sliding bearing 510 essentially corresponds to the structural sliding bearing 210. The identical components will not be discussed further below.

[0066] The structural sliding bearing 510 differs from the structural sliding bearing 210 in that the sliding plate 516 has two stops 538. The stops 538 are located centrally, laterally, and opposite each other on the sliding plate 516. Both stops 538 project towards the bearing base 212, so that the stops 538 are positioned between the bearing base 212 and the sliding plate 516. This limits the movement of the sliding plate 516 relative to the bearing base 212. In this embodiment, the stops 538 are designed such that the structural sliding bearing 510 is transformed into a fixed bearing.

[0067] The Fig. 11 Figure 1 shows a perspective view of an exemplary structural sliding bearing 610, which is not part of the present invention. The structural sliding bearing 610 is essentially identical to the structural sliding bearing 210. The identical components will not be discussed further below.

[0068] The structural sliding bearing 610 differs from the structural sliding bearing 210 in that it is designed as a pot bearing. The intermediate bearing part 614 is designed as a pot lid on which the sliding plate 216 rests in a sliding manner. The lower bearing part 612, on the other hand, has a pot with an elastomer cushion 640 to allow for minor rotations or displacements of the pot lid and thus of the pot bearing. All the advantages of the main sliding surface discussed above apply accordingly.

[0069] In the Fig. 12 A schematic side view of a structural support system 700 according to a first embodiment of the invention is shown. Here, the advantages of the previously described structural sliding bearings are realized by means of two separate sliding bearings 710A and 710B. Thus, the structural support system 700 has a first sliding bearing 710A and a second sliding bearing 710B to connect a first structural component 712 with a second structural component 714. In this example, the first sliding bearing 710A and the second sliding bearing 710B are each designed as sliding tilting bearings.

[0070] The first sliding tilt bearing 710A and the second sliding tilt bearing 710B have essentially identical components. Thus, the first sliding tilt bearing 710A comprises a bearing base 716A, which can be connected to the first structural component 712, a sliding plate 718A, which can be connected to the second structural component 714, and a bearing intermediate component 720A, or tilting element, which is arranged between the bearing base 716A and the sliding plate 718A. A flat main sliding surface 722A of the first sliding tilt bearing 710A extends between the bearing intermediate component 720A and the sliding plate 718A.

[0071] The second sliding tilting bearing 710B also has a bearing base 716B, which can be connected to the first structural part 712, a sliding plate 718B, which can be connected to the second structural part 714, and a bearing intermediate part 720B or a tilting part, which is arranged between the bearing base 716B and the sliding plate 718B. Accordingly, a flat main sliding surface 722B of the second sliding tilting bearing 710B extends between the bearing intermediate part 720B and the sliding plate 718B.

[0072] Both sliding tilt bearings 710A and 710B form a uniaxially guided bearing pair, in which the main sliding surface 722A of the first sliding tilt bearing 710A is arranged in a first sliding plane 724A inclined to the horizontal H. The main sliding surface 722B of the second sliding tilt bearing 710B is also arranged in a second sliding plane 724B inclined to the horizontal H. Both sliding planes 724A and 724B meet at a common horizontal intersection line S, which thus forms the axis of movement A of the bearing pair and along which the two sliding plates 718A and 718B can move. This allows for corresponding displacements of the first structural element 712 relative to the second structural element 714.

[0073] The two inclined main sliding surfaces 722A and 722B are arranged such that the first sliding plane 724A and the second sliding plane 724B form the shape of an inverted gable roof. Alternatively, the shape of a normal gable roof (not shown) would also be conceivable, with the axis of movement A forming the ridge of the gable roof. Furthermore, the two inclined main sliding surfaces 722A and 722B are of equal size and symmetrical to each other with respect to a plane of symmetry E extending vertically through the line of intersection S. Alternatively, the two inclined main sliding surfaces 722A and 722B could also be of different sizes (not shown).

[0074] Furthermore, both main sliding surfaces 722A and 722B each feature a sliding material 726 to reduce friction between the two intermediate bearing parts 720A and 720B and the respective sliding plates 718A and 718B. In this case, each of the two inclined main sliding surfaces 722A and 722B includes a permanently lubricated polymer sliding disc, which is mounted in a recess 728 on the respective intermediate bearing part 720A and 720B. The polymer sliding disc is made of PTFE, UHMWPE, POM, and / or PA and has pre-formed lubrication pockets in which the lubricant can be stored and distributed evenly over the entire contact surface. As a result, the sliding material 726 has a very low coefficient of friction and is particularly wear-resistant. In the present embodiment, the coefficient of friction is a maximum of 0.03.

[0075] The special arrangement of the two main sliding surfaces 722A and 722B enables a functional combination of vertical and horizontal force transmission within the bearing pair. Thus, the bearing pair can absorb vertically acting forces via the two inclined main sliding surfaces 722A and 722B and transfer them from the second structural component 714 to the first structural component 712. In this embodiment, vertically acting forces are therefore introduced from the second structural component 714 to the first structural component 712 via the two sliding plates 718A and 718B, the two intermediate bearing components 720A and 720B, and the lower bearing components 716A and 716B. Furthermore, the two mutually inclined main sliding surfaces 722A and 722B can also absorb horizontal forces directed perpendicular to the axis of movement A and transfer them accordingly between the two structural components 712 and 714.

[0076] The ratio of permissible vertical loads to horizontal forces perpendicular to the axis of movement A can be adjusted by the inclination of the two main sliding surfaces 722A and 722B, or of the first sliding plane 724A and the second sliding plane 724B. Thus, both sliding planes 724A and 724B enclose a first angle α, which is selected such that no gap occurs in the area of ​​the two main sliding surfaces 722A and 722B during the service life of the structural support system 700. The first angle α of the structural support system 700 is even selected such that no gap occurs in the area of ​​the two main sliding surfaces 722A and 722B during the ultimate limit state of the structural support system 700. The illustrated structural support system 700 has a first angle α of 140 degrees.However, if the structural sliding bearing 700 is to be designed for lower horizontal forces, a more obtuse first angle α can also be used, such as between 160 degrees and 180 degrees or exactly 168 degrees.

[0077] Alternatively or additionally, the inclination of the first sliding plane 724A and the second sliding plane 724B can also be specified via their angle of intersection with the horizontal H. Thus, both sliding planes 724A and 724B are inclined downwards with respect to the horizontal H by a second angle β. In the present embodiment, both sliding planes 724A and 724B of the structural support system 700 have the same second angle β, which here is 20 degrees. However, with lower horizontal force applications, a shallower second angle β can also be selected, such as between 0 degrees and 10 degrees or exactly 6 degrees. It would also be possible for the sliding plane 724A to have a different second angle β than the sliding plane 724B in order to selectively accommodate different force applications from different directions (not shown).

[0078] Since the two sliding tilt bearings 710A and 710B in the 700 building support system each have a separate sliding plate 718A and 718B, simple height adjustment is also possible here using the corresponding bearing pair. The principle of the in Fig. 8 The height adjustment shown is applied, wherein the two sliding plates 718A and 718B each represent a sliding plate part 316A and 316B respectively of the two-part sliding plate 316.

[0079] In the Fig. 13 A schematic side view of a building support system 700 according to a second embodiment of the invention is shown. The building support system 700 of the second embodiment essentially corresponds to the building support system 700 of the first embodiment. The identically constructed components will not be discussed further below.

[0080] The second embodiment of the structural support system 700 differs from the first embodiment in that the two inclined main sliding surfaces 722A and 722B are arranged such that the first sliding plane 724A and the second sliding plane 724B form the shape of a normal gable roof. Furthermore, the first sliding tilting bearing 710A has a lateral stop device 730A that limits the movement of the sliding plate 718A relative to the bearing base 716A. The stop device 730A is arranged on a side of the first sliding tilting bearing 710A facing the axis of movement A. For this purpose, the stop device 730A is formed in one piece and attached to the bearing base 716A. In addition, the stop device 730A has a sliding device 732A in the form of a sliding strip that guides the sliding plate 718A in a direction parallel to the axis of movement A.The lateral distance of the stop device 730A from the bearing base 716A, and thus also from the sliding plate 718A, can be adjusted using an adjustment device. This is achieved here by a screw connection between the bearing base 716A and the stop device 730A.

[0081] Furthermore, the second sliding rocker bearing 710B has a lateral stop device 730B that limits the movement of the sliding plate 718B relative to the bearing base 716B. The stop device 730B is arranged on one side of the second sliding rocker bearing 710B that faces the axis of movement A. For this purpose, the stop device 730B is formed in one piece and attached to the bearing base 716B. The stop device 730B also has a sliding element 732B in the form of a guide rail that guides the sliding plate 718B in a direction parallel to the axis of movement A. The lateral distance of the stop device 730B from the bearing base 716B, and thus also from the sliding plate 718B, can be adjusted by means of an adjustment device. This is also achieved here by a screw connection between the bearing base 716B and the stop device 730B.

[0082] If a moment M acts on the second structural component 714 about an axis parallel to the axis of movement A in a clockwise direction, it is pulled against the stop device 730A of the first sliding rocker bearing 710A and is supported on the other side at the instantaneous center of rotation MP in the base of the second sliding rocker bearing 710B. This results in a force F acting in the stop device 730A, which counteracts the rotation of the second structural component 714. The same applies to a counterclockwise moment. In this case, the second structural component 714 is pulled against the stop device 730B of the second sliding rocker bearing 710B and is supported on the other side at the instantaneous center of rotation in the base of the first sliding rocker bearing 710A.

[0083] In this embodiment, both stop devices 730A and 730B are arranged on the side of the corresponding sliding tilting bearing 710A and 710B that is higher in the vertical direction. If the acting moments are small or negligible, the vertical force component of the dead weight relative to the operational load acts primarily on the bearing, meaning that the stop devices 730A and 730B are completely free of any force. Therefore, with appropriate dimensioning, the stop devices 730A and 730B are only rarely activated, which is advantageous for their service life due to fatigue.

[0084] The Fig. 14 Figure 1 shows a schematic side view of a structural support system 700 according to a third embodiment of the invention. The structural support system 700 of the third embodiment essentially corresponds to the structural support system 700 of the second embodiment. The identically constructed components will not be discussed further below.

[0085] The structural support system 700 of the third embodiment differs from the structural support system 700 of the second embodiment in that the first sliding bearing 710A and the second sliding bearing 710B are designed as elastomeric bearings. For this purpose, the respective intermediate bearing parts 720A and 720B have an elastomeric layer which provides corresponding deformation properties.

[0086] In the Fig. 15 A schematic top view of a structural support system 800 according to a fourth embodiment of the invention is shown. The structural support system 800 has two pairs of bearings 810 and 820 arranged along an axis B. Each pair of bearings 810 and 820 has two plain bearings 810A, 810B, 820A, and 820B. Thus, the first pair of bearings 810 comprises a first plain bearing 810A and a second plain bearing 810B. The second pair of bearings 820 has a first plain bearing 820A and a second plain bearing 820B.

[0087] The second structural element 714 is supported by the structural support system 800. The two pairs of bearings 810 and 820 are arranged at the elongated ends of the second structural element 714, thus forming a simply supported beam. The first pair of bearings 810 corresponds to the bearing pair of the structural support system 700 of the first embodiment, as shown in the Fig. 12 This is shown. Here, the two main sliding surfaces, angled towards each other, are arranged in such a way that the corresponding sliding planes form an upside-down saddle roof.

[0088] The second bearing pair 820 is essentially the same as that of the first embodiment. However, here the two mutually angled main sliding surfaces are arranged such that the corresponding sliding planes form the shape of a normal gable roof. Thus, the mutually angled main sliding surfaces of the bearing pairs 810 and 820 are arranged such that the corresponding sliding planes of the first bearing pair 810 and the second bearing pair 820 alternately form the shape of a gable roof and the shape of an inverted gable roof along axis B. This principle can also be applied to more than two consecutive bearing pairs. The alternating arrangement of the mutually angled main sliding surfaces along axis B allows for particularly effective absorption of torsional moments in the second structural element 714.In another embodiment, 800 bearing pairs of the second or third embodiment of the building support system 700 are used for the building support system.

[0089] The Fig. 16 Figure 1 shows a schematic top view of a structural support system 900 according to a fifth embodiment of the invention. The structural support system 900 has four bearing pairs 910, 920, 930, 940 arranged along an axis B. Each bearing pair 910, 920, 930, 940 has two sliding bearings. Thus, all bearing pairs 910, 920, 930, 940 include a first sliding bearing 910A, 920A, 930A, 940A and a second sliding bearing 910B, 920B, 930B, 940B. The second structural component 914 consists of two single-span beams 914A, 914B. Both single-span beams 914A, 914B are arranged directly adjacent to one another along the axis B. The individual single-span beams 914A, 914B could, for example, represent track sections, road sections or sections of a pipeline.

[0090] As before, the two simply supported beams 914A and 914B are held at their elongated ends by the bearing pairs 910, 920, 930, and 940. The first simply supported beam 914A is supported by the first bearing pair 910 and the second bearing pair 920. The second simply supported beam 914B, on the other hand, is supported by the third bearing pair 930 and the fourth bearing pair 940.

[0091] All bearing pairs 910, 920, 930, 940 essentially correspond to the bearing pair of the structural support system 700 of the first embodiment. However, here the mutually inclined main sliding surfaces are arranged such that the corresponding sliding planes of the bearing pairs 910, 920, 930, 940 alternately form the shape of a gable roof and the shape of an inverted gable roof along axis B for every second bearing pair. In particular, the two sliding planes of the first bearing pair 910 and the fourth bearing pair 940 have the shape of a gable roof. The two sliding planes of the second bearing pair 920 and the third bearing pair 930, on the other hand, are designed in the shape of an inverted gable roof. Thus, the same arrangement of the main sliding surfaces or the sliding planes is used in the area of ​​the connection point of both simply supported beams 914A, 914B.

[0092] The inclination of the main sliding surfaces of the first sliding tilt bearing 920A of the second bearing pair 920 and of the first sliding tilt bearing 930A of the third bearing pair 930 are the same. Therefore, the corresponding first and second angles are also identical. The same applies to the main sliding surfaces of the second sliding tilt bearing 920B of the second bearing pair 920 and of the second sliding tilt bearing 930B of the third bearing pair 930. This minimizes any vertical displacement in the area of ​​the connection point between the two simply supported beams 714A, 714B during lateral expansion in the structure. In a further embodiment, bearing pairs from the second or third embodiment of the structural support system 700 are used for the structural support system 900. REFERENCE MARK
