USE OF A STRUCTURAL SLIDING BEARING

Description

[0001] The present invention relates to the use of a structural sliding bearing for connecting a first and second structural part.

[0002] 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. Several such structural sliding bearings together form a structural bearing system with a corresponding number of connection points between the respective structural components.

[0003] Such structural sliding bearings for connecting various structural components are, in principle, sufficiently known from the state of the art.

[0004] The documents CN 108 532 451 A, DE 35 17 895 A1, DE 101 28 362 A1 and DE 40 39 523 A1 show structural sliding bearings of this type.

[0005] Document CN 108 532 451 A discloses a V-shaped, trough-like rubber pad for a slideway.The V-shaped cymbal rubber pad for the slide track includes 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, and 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 V-depressed 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.Due to the rubber layers vulcanized on the surfaces of the upper seat plate and the lower seat plate, the friction force between a support plate and a pinner is increased, a bolt anchoring system of an original basin type is eliminated, and the support is installed quickly and conveniently; and a V-shaped slideway is arranged between the upper seat plate and the middle plate, and the functions of horizontal limitation and guiding sliding are achieved, and the support is compact in structure and light in weight.

[0006] A cap-type plain bearing is known from document DE 35 17 895 A1. This comprises two tilting strips arranged on either side of the cap 1 and running parallel to each other, 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.

[0007] Document DE 101 28 362 A1 discloses a bearing system for supporting a plurality of consecutively 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 each other in the central longitudinal plane of the guideway girder 2. When traveling over the track at approximately 500 km / h, the high-speed railway 3 causes the guideway girder 2 to undergo a sinusoidal oscillation 8, causing the girder to bend accordingly between the pairs of bearings 4, 5, 6. This creates tilting and sliding movements in the bearing units, which must be accommodated by means of a suitable bearing design and suitable bearing materials, without causing offsets between two guideway girders 2 in the joint area.

[0008] A sliding bearing for construction purposes is known from document DE 40 39 523 A1. This bearing comprises two vertical supports 17 arranged parallel to the sliding direction and relative 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. A compact insert made of synthetic rubber is located between each rail and the bottom of the groove. Each profile element 1 has a closed bore with two openings on the support side, which forms the groove for receiving the tilting rails.

[0009] Structural bearings generally transfer vertical and horizontal loads and enable rotations and relative displacements where necessary. Structural sliding bearings are a special type of structural bearing, which generally serves 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 enable relative movements between two structural components of the structure in question, which can arise, for example, from the use of the structure or from possible external influences such as wind or an earthquake. The use of such structural bearings or corresponding structural bearing systems can thus prevent, in particular, damage to the corresponding structures.

[0010] According to the DIN EN 1337 standard, various designs and functionalities of structural bearings are known. Depending on their design and functional principle, they have a different structure and a different number of degrees of freedom. Structural bearings can be designed either as fully fixed bearings or as fully or unidirectionally movable bearings. According to the DIN 4141-13 standard, there are also solutions in which 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.

[0011] 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. As can be seen from the figure, 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 cover 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.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 enables the sliding plate 22 to slide along the main sliding surface 24 with as little resistance as possible.

[0012] 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. At the same time, the elastomer cushion 16 enables any rotation of the pot sliding bearing 10. This occurs through the 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 compressive load is applied to the elastomer cushion 16. Furthermore, 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.

[0013] In addition, the pot-type plain 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 cover 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 pot-type plain 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. Thus, 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 movement axis is facilitated.

[0014] Therefore, when horizontal forces act on the pot sliding bearing 10 that run parallel to the guide rail 28, the sliding plate 22 moves relative to the underlying pot cover 20. These force components are therefore not absorbed and transmitted by the pot sliding bearing 10. Corresponding movements of the structural components can thus be compensated.

[0015] The situation is different for horizontal forces acting transversely to the guide rail 28. The sliding plate 22 cannot execute any horizontal movements transversely to the guide rail 28. Therefore, such directed forces are absorbed and transmitted by the guide rail 28 or the cup sliding bearing 10. Corresponding movements of the structural components cannot be compensated for.

[0016] In addition to the Fig. 1 In addition to the embodiment shown, there are also solutions in which the guide rail is formed on the sliding plate and the groove is formed on the pot lid. The previously discussed basic functional principle regarding the degrees of freedom and force transfer between the pot lid and the sliding plate applies accordingly here.

[0017] In 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. 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.

[0018] 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. Thus, 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.

[0019] 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.

[0020] In this embodiment, 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. Thus, any horizontal forces transverse to the two lateral guide rails 126 are absorbed, thereby defining the movement axis of the spherical bearing 110. As with the cup-shaped plain bearing 10, 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. 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, which simplifies the movement of the sliding plate 120 along the movement axis accordingly.

[0021] As soon as horizontal forces parallel to the two lateral guide rails 126 act on the spherical bearing 110, the sliding plate 120 moves 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.

[0022] The opposite occurs with horizontal forces acting transversely to the two lateral guide rails 126. The sliding plate 120 cannot perform corresponding horizontal movements in this direction. Thus, 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 transversely to the two lateral guide rails 126 are therefore absorbed by the spherical bearing 110. Corresponding movements of the structural components cannot therefore be compensated.

[0023] In the described forms of uniaxially guided structural sliding bearings, there is a functional separation between vertical and horizontal force transfer. While the vertical loads are absorbed by the respective main sliding surface of the bearing intermediate part, horizontal forces acting perpendicular to the axis of movement are transferred to the corresponding guide rails. As stipulated in Section 6.8 of the DIN EN 1337-2:2004 standard for bearings in construction, the known structural sliding bearings are dimensioned such that, in their service condition, no gaping joint occurs in the area of the horizontal main sliding surface. In this disclosure, a gaping joint is understood to mean partial lift-off within the sliding surface. Thus, the overall gaping of the joint is decisive for the load-bearing capacity of the structural sliding bearing.

[0024] According to the standard DIN EN 1990:2010-12 for fundamentals of structural design, 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.

[0025] For special structural sliding bearings or structural bearing systems designed for extreme conditions such as an earthquake, 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.

[0026] Although, for the sake of simplicity, 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. In the present disclosure, such orientation specifications refer only to the plane of movement of the structural sliding bearing or structural bearing system. This applies in particular if, for example, the structural sliding bearing or structural bearing system is installed at an angle. In this case, the orientation of the horizontal main sliding surface may differ from a horizontal plane in the narrower sense and may be inclined accordingly. The same applies to the vertical guide surfaces arranged perpendicular to them and the correspondingly described force effects.

[0027] Despite this proven principle of force transfer, it has been found that, particularly with long-term use of such structural sliding bearings, large 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 to impairments in the sliding behavior of the structural sliding bearing. This is primarily due to the fact that in such rail constructions there is a certain amount of play between the respective components, which is fundamentally unavoidable - particularly in the area of the vertical sliding surfaces between the guide rail and the sliding plate. Thus, a gaping joint is normally present in the area of the vertical guide surfaces when the structural sliding bearing is in use. This play orThis gaping joint 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 play, the guide surfaces of the rail structure can only be lubricated initially; a permanent lubricant supply is not guaranteed. Furthermore, a sliding material must be used that can absorb high local pressures. Ultimately, sliding materials are used here that exhibit relatively poor sliding behavior due to relatively high coefficients of friction and relatively high wear.

[0028] In particular, single-axis guided structural sliding bearings with a central guide rail are of limited use when absorbing very high forces. When two lateral guide rails are used, however, the rotation of the bearing around the vertical axis is hindered. Ultimately, the structural sliding bearings described represent complex structures that require correspondingly high installation space and manufacturing and maintenance costs. The same disadvantages apply to structural bearing systems that incorporate such structural sliding bearings. It is therefore an object of the present invention to provide an improved structural sliding bearing that, on the one hand, is as simple in design as possible and, on the other hand, operates maintenance-free and reliably for as long as possible, even under increased force application, so that costs and effort during production and use can be reduced.

[0029] The solution to the above-mentioned problem is achieved according to the invention by using a structural sliding bearing according to claim 1. Advantageous further developments of the invention emerge from the dependent claims 2 to 17.

[0030] In the inventive use of the structural sliding bearing, 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.

[0031] The two partial sliding surfaces of the main sliding surface, which are inclined towards each other, achieve a functional combination of vertical and horizontal force transfer within the structural sliding bearing. This means that any vertical forces 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 completely fulfilled by the main sliding surface. This considerably simplifies the design of the structural sliding bearing and the corresponding manufacturing costs can be reduced. 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 in oron the sliding plate is no longer necessary, allowing the dimensions and, in particular, the thickness of the sliding plate to be reduced. Eliminating the rail construction also eliminates the potential for dirt and foreign matter to enter this area due to lateral movement.

[0032] By adjusting the inclination of the two partial sliding surfaces relative to each other, or by selecting the first angle, the ratio between the maximum possible vertical force and the horizontal force absorbed by the structural sliding bearing can be optimally adjusted. By appropriately selecting the inclination of the two partial sliding surfaces relative to each other, 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. If, for example, 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 cannot lift off the intermediate bearing part when the structural sliding bearing is in use.At the same time, a sliding material with the lowest possible friction can be used in the area of the main sliding surface in order to still facilitate the movement of the sliding plate in the direction of the movement axis.

[0033] Due to the continuous and even pressure in the area of the main sliding surface, permanently lubricated sliding materials, such as those specified in the DIN EN 1337-2:2004 standard for bearings in the construction industry, are now particularly suitable for the guide. These materials have a low coefficient of friction and are particularly wear-resistant. Tests conducted by the applicant have already demonstrated durability with corresponding sliding materials at a combined sliding distance up to 25 times greater in the current leading main sliding surface than in the previously separate, initially lubricated guide surfaces.

[0034] Furthermore, 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.

[0035] Preferably, the main sliding surface has exactly two, most preferably only two, partial sliding surfaces. This allows the structural sliding bearing according to the invention to be constructed as simply as possible. 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. In this case, in addition to the mutually angled sliding planes, the two mutually inclined partial sliding surfaces also intersect along the movement axis. Alternatively, the two inclined partial sliding surfaces can also be formed separately from one another in the respective sliding planes.

[0036] 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.

[0037] Preferably, the two sliding planes are arranged so that the intersection line runs horizontally. Thus, the movement axis of the structural sliding bearing also runs horizontally. With this configuration, the structural sliding bearing is loaded as evenly as possible with regard to force transfer. Furthermore, the sliding plate can move evenly with identical resistance in both directions of the movement axis. As explained above, the horizontal orientation is to be understood with reference to the movement plane of the structural sliding bearing. Thus, the intersection line can also have an orientation other than a horizontal line in the strict sense.

[0038] If the loads on the structural sliding bearing are further increased beyond the serviceable condition, the ultimate limit state occurs. According to the DIN EN 1990:2010-12 standard for fundamentals of structural design, this condition is associated with collapse or other forms of structural failure. Therefore, even those limit states that affect the safety of persons and / or the safety of the structure are classified as ultimate limit states. This has the advantage that, even in this condition, it is still ensured that no gaping joint develops in the area of the main sliding surface and that the sliding plate does not lift off the intermediate bearing part.

[0039] In a further development, 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.

[0040] Advantageously, 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.

[0041] Preferably, 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.

[0042] Preferably, at least two partial sliding surfaces angled to one another are arranged such that the corresponding sliding planes form the shape of an inverted gable roof. Here, too, 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 inverted roof shape, it is possible to design the sliding plate to be thicker in the center, which is subject to the highest load, than at the edges, without requiring additional installation space in the vertical direction. This allows for further installation space savings despite increased loads.

[0043] Furthermore, 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. Furthermore, especially when forces are applied with equal force from all sides, it is advantageous if the conditions for displacement of the sliding plate in both directions along the axis of movement are as similar as possible. In addition, the structural sliding bearing has a simple design and is therefore cost-effective to manufacture. As already explained above, the vertical direction is to be understood with reference to the plane of movement of the structural sliding bearing. Thus, the vertical direction can also have an orientation other than a vertical in the narrower sense.

[0044] Preferably, at least two partial sliding surfaces of the main sliding surface, which are angled to one another, are of different sizes. This configuration is particularly advantageous when horizontal forces of different magnitudes act on the structural sliding bearing from different directions. Thus, 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. Alternatively or additionally, the two opening angles between the plane of symmetry and the respective inclined partial sliding surface could also be of different sizes.

[0045] Advantageously, at least one sliding plane is inclined downwards by a second angle of 6 degrees relative to the horizontal. With a steeper second angle, the respective inclined partial sliding surface can absorb correspondingly higher horizontal forces perpendicular to the axis of movement. At the same time, it is still possible to use a sliding material with a low coefficient of friction in the area of the main sliding surface. This prevents a gaping joint or the sliding plate from lifting off the intermediate bearing part. It also ensures that the sliding plate moves along the axis of movement with as little resistance as possible. As explained above, 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.Particularly preferably, the second angle corresponds at least to the permissible friction to be applied for the design.

[0046] Furthermore, the first angle can be 168 degrees. With a more acute first angle, the respective inclined partial sliding surface can absorb correspondingly higher horizontal forces perpendicular to the movement axis. At the same time, it is still possible to use a sliding material with a low coefficient of friction in the area of the main sliding surface. This prevents a gaping joint or even the sliding plate from lifting off the bearing intermediate part. It also ensures the sliding plate moves along the movement axis with as little resistance as possible.

[0047] Preferably, 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 towards or apart from one another synchronously along the corresponding sliding planes transverse to the movement axis, the horizontal distance between the two sliding plate parts and the lower bearing part of the structural sliding bearing also changes.However, if, for example, 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 will be tilted relative to the first structural part.

[0048] In a further development, 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.

[0049] Alternatively, 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 lower bearing part a corresponding concave section, with the convex section of the spherical cap being arranged to slide in the concave section of the lower bearing part. Here, too, vertically acting forces are effectively transferred from the sliding plate to the lower bearing part by means of the spherical cap. Twisting between the sliding plate and the lower bearing part is also possible. In combination with the design of the at least two mutually inclined partial sliding surfaces in the shape of an upside-down gable roof, this also significantly reduces the eccentricities resulting from acting horizontal forces. At the same time, the sliding plate is stronger at the most highly stressed center than at the edges.This means that the entire sliding plate can be made thinner and thus produced more economically.

[0050] 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 maintaining the same outer diameter, reduces the pressure area, thereby increasing the 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.This allows the structural sliding bearing to absorb even greater forces – even without enlarging the main sliding surface. Furthermore, 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. Thus, both the selection of the initial angle and the selection of the recess diameter offer the possibility of adjusting the ratio of the vertical and horizontal forces that can be absorbed.

[0051] Preferably, 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.

[0052] Advantageously, a sliding material, preferably a polymer sliding washer, is arranged on the concave section of the bearing base, and the recess is formed in the sliding material. The sliding material or the polymer sliding washer can reduce friction in the area of the secondary sliding surface of the spherical bearing. For this purpose, the sliding material is generally in contact with the convex section of the spherical cap. Thus, the recess in the sliding material prevents such contact with the spherical cap in this area, achieving the advantages already discussed. Furthermore, the recess in the sliding material is also easy to manufacture. For example, an annular polymer sliding washer can be used, which is attached to the concave section of the bearing base in the area of the secondary sliding surface.

[0053] The structural sliding bearing expediently 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 up to a predetermined extent. Thus, the structural sliding bearing can also be converted into a fixed bearing. Such a bearing, on the one hand, has no play transverse to the mutually inclined partial sliding surfaces. On the other hand, it has low torsional resistance.

[0054] 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.

[0056] Identical components in the different embodiments are identified by the same reference numerals.

[0057] In the Fig. 3 bis 7 The schematic structure of a structural sliding bearing 210 according to a particularly advantageous first embodiment is shown. 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.

[0058] The bearing base 212 has a concave section 218 in which the spherical cap is slidably received with its convex section 220. 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. In the area of the secondary sliding surface 222, a sliding material 224 in the form of a polymer sliding disk is arranged on the concave section 218 of the bearing base 212. 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 enables rotation about the vertical and horizontal axes.

[0059] As can be seen in particular from the exploded view of the Fig. 4 As can be seen, the sliding plate 216 rests slidably on the calotte in order to be connected above with the second structural part. Thus, the main sliding surface 226 of the structural sliding bearing 210 is arranged between the calotte and the sliding plate 216. As the top view of the Fig. 5 as well as the cross sections of the Fig. 6 und 7 As shown, the main sliding surface 226 has two partial sliding surfaces 228A and 228B inclined relative to one another. 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 movement axis A of the structural sliding bearing 210, along which the sliding plate 216 can move. Thus, corresponding displacements of the first structural part relative to the second structural part can be permitted.

[0060] 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. The shape of an upside-down gable roof (not shown) would also be conceivable here, with the movement axis 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 one another with respect to a plane of symmetry E running vertically through the section line S. Alternatively, the two mutually inclined partial sliding surfaces 228A and 228B could also be of different sizes (not shown).

[0061] In addition, the main sliding surface 226 has a sliding material 232 to reduce the friction between the calotte 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 disk, each mounted in a recess 234 on the calotte. The polymer sliding disk is made of PTFE, UHMWPE, POM, and / or PA and has prefabricated lubrication pockets in which the lubricant can be stored and released evenly across the entire contact surface. As a result, the sliding material 232 has a very low coefficient of friction and is particularly wear-resistant in use. In the present embodiment, the coefficient of friction is a maximum of 0.03.

[0062] The special arrangement of the main sliding surface 226 and the two mutually inclined partial sliding surfaces 228A and 228B achieves a functional combination of vertical and horizontal force transfer. 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 part to the first structural part. In this embodiment, vertically acting forces are thus transferred from the second structural part to the first structural part via the sliding plate 216, the calotte, 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 transversely to the movement axis A and transfer them accordingly between the two structural parts.

[0063] The ratio of absorbable vertical loads and horizontal forces transverse to the movement axis 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 in the service state of the structural sliding bearing 210, no gaping joint occurs in the area of the main sliding surface 226. The first angle α of the structural sliding bearing 210 is even selected such that even in the ultimate limit state of the structural sliding bearing 210, no gaping joint occurs in the area of the main sliding surface 226. The Fig. 3 bis 7 The structural sliding bearing 210 shown 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.

[0064] Alternatively or additionally, the inclination of the two sliding planes 230A and 230B can also be specified via their intersection angle relative to the horizontal H. Thus, both sliding planes 230A and 230B are inclined downwards relative to the horizontal H by a second angle β. In the present embodiment, 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 force action, a particularly steep angle can also be selected. 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 specifically absorb force effects of different magnitudes from different directions (not shown).

[0065] In the Fig. 8 A sequence of two schematic cross-sectional views of a structural sliding bearing 310 according to a second embodiment is shown, illustrating a height adjustment of the structural sliding bearing. The structural sliding bearing 310 essentially corresponds to the structural sliding bearing 210 of the first embodiment. The identical components will not be discussed further below.

[0066] However, the structural sliding bearing 310 differs from the structural sliding bearing 210 of the first embodiment in that the sliding plate 316 is formed in several parts, and the distance between the corresponding sliding plate parts 316A and 316B is adjustable. In this embodiment, 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.

[0067] In the left of the two cross sections of the Fig. 8 An initial state of the structural sliding bearing 310 prior to height adjustment is shown. The two sliding plate parts 316A and 316B are arranged separated from each other by the first horizontal distance d1. Both sliding plate parts 316A and 316B have the same horizontal distance from the movement axis A. With this arrangement, the structural sliding bearing 310 has a first overall height G1.

[0068] If the two sliding plate parts 316A and 316B are now synchronously pushed towards or apart from each other along the respective partial sliding surfaces 228A and 228B, the first total height G1 of the structural sliding bearing is changed by a height difference ΔH. This enables a simple height adjustment of the structural sliding bearing 310. In the right cross section of the Fig. 8 For example, a final state of the structural sliding bearing 310 is shown after the two sliding plate parts 316A and 316B have been pushed towards each other. As can be seen from 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 from the movement axis A. Thus, the first total height G1 is increased by the height difference ΔH to a second total height G2. If, on the other hand, the two sliding plate parts 316A and 316B are pushed apart, the first total height G1 is decreased accordingly.

[0069] The Fig. 9 shows a schematic exploded view of a structural sliding bearing 410 according to the invention according to an advantageous third embodiment. The structural sliding bearing 310 essentially corresponds to the structural sliding bearing 210 of the first embodiment. The identical components will not be discussed further below.

[0070] However, the structural sliding bearing 410 differs from the structural sliding bearing 210 of the first embodiment in that the concave section 418 of the bearing base 412 has a recess 436 at a lower pole P, so that in the region of the recess 436, the convex section 220 of the calotte does not come into contact with the concave section 418 of the bearing base 412. In the present embodiment, this recess 436 is formed in the polymer sliding disk of the sliding material 424 in the region of the secondary sliding surface 422. The recess 436 has a circular shape that is centered on the lower pole P.

[0071] With the recess 436 at the lower pole P, the radius of gyration is increased. Accordingly, 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, even greater forces can be absorbed by the structural sliding bearing 410. Furthermore, the structural sliding bearing 410 with the recess 436 offers a further adjustment option for adapting the ratio between the absorbable vertical forces and horizontal forces. Thus, the inclination of the two mutually inclined partial sliding surfaces 228A and 228B can be matched to the diameter D of the recess 436 in order to optimally design the structural sliding bearing 410 for a wide variety of force effects.

[0072] In the Fig. 10 A schematic exploded view of a structural sliding bearing 510 according to the invention is shown, according to an advantageous fourth embodiment. The structural sliding bearing 510 essentially corresponds to the structural sliding bearing 210 of the first embodiment. The identical components will not be discussed further below.

[0073] The structural sliding bearing 510 differs from the structural sliding bearing 210 of the first embodiment in that the sliding plate 516 has two stops 538. The stops 538 are mounted centrally, laterally, and opposite each other on the sliding plate 538. Both stops 538 protrude toward the bearing base 212, so that the stops 538 are arranged between the bearing base 212 and the sliding plate 516. Thus, the movement of the sliding plate 516 relative to the bearing base 212 is limited. In this embodiment, the stops 538 are designed such that the structural sliding bearing 510 is converted into a fixed bearing.

[0074] The Fig. 11 shows a perspective view of a structural sliding bearing 610 according to the invention according to an advantageous fifth embodiment. The structural sliding bearing 610 essentially corresponds to the structural sliding bearing 210 of the first embodiment. The identical components will not be discussed further below.

[0075] However, the structural sliding bearing 610 differs from the structural sliding bearing 210 of the first embodiment in that it is designed as a pot bearing. Thus, the intermediate bearing part 614 is designed as a pot cover, 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 cover arranged above it and thus of the pot bearing. All advantages of the main sliding surface discussed apply accordingly.

[0076] In the Fig. 12 A schematic side view of a structural bearing system 700 according to the invention is shown according to a first embodiment. Here, the advantages of the previously described structural sliding bearings are realized by two separate sliding bearings 710A and 710B. Thus, the structural bearing system 700 has a first sliding bearing 710A and a second sliding bearing 710B for connecting a first structural part 712 to a second structural part 714. In this example, the first sliding bearing 710A and the second sliding bearing 710B are each designed as sliding tilting bearings.

[0077] The first sliding tilt bearing 710A and the second sliding tilt bearing 710B essentially have identical components. Thus, the first sliding tilt bearing 710A includes a bearing base 716A that can be connected to the first structural part 712, a sliding plate 718A that can be connected to the second structural part 714, and an intermediate bearing part 720A or a tilting part that 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 intermediate bearing part 720A and the sliding plate 718A.

[0078] The second sliding tilt bearing 710B also has a lower bearing part 716B that can be connected to the first structural part 712, a sliding plate 718B that can be connected to the second structural part 714, and an intermediate bearing part 720B or a tilting part that is arranged between the lower bearing part 716B and the sliding plate 718B. Accordingly, a flat main sliding surface 722B of the second sliding tilt bearing 710B extends between the intermediate bearing part 720B and the sliding plate 718B.

[0079] 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 in a common horizontal intersection line S, which thus forms the movement axis A of the bearing pair and along which the two sliding plates 718A and 718B can move. Thus, corresponding displacements of the first structural part 712 relative to the second structural part 714 can be permitted.

[0080] 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 upside-down gable roof. The shape of a normal gable roof (not shown) would also be conceivable here, with the movement axis A forming the ridge of the gable roof. Furthermore, the two mutually inclined main sliding surfaces 722A and 722B are of equal size and symmetrical to one another with respect to a plane of symmetry E running vertically through the intersection line S. Alternatively, the two mutually inclined main sliding surfaces 722A and 722B could also be of different sizes (not shown).

[0081] In addition, both main sliding surfaces 722A and 722B each have a sliding material 726 to reduce the friction between the two intermediate bearing parts 720A and 720B and the respective sliding plate 718A and 718B. In this case, each of the two inclined main sliding surfaces 722A and 722B includes a permanently lubricated polymer sliding disk, each mounted in a recess 728 on the respective intermediate bearing part 720A and 720B. The polymer sliding disk is made of PTFE, UHMWPE, POM, and / or PA and has prefabricated lubrication pockets in which the lubricant can be stored and released evenly across the entire contact surface. As a result, the sliding material 726 has a very low coefficient of friction and is particularly wear-resistant in use. In the present embodiment, the coefficient of friction is a maximum of 0.03.

[0082] The special arrangement of the two main sliding surfaces 722A and 722B also achieves a functional combination of vertical and horizontal force transfer 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 part 714 to the first structural part 712. In this embodiment, vertically acting forces are thus introduced from the second structural part 714 into the first structural part 712 via the two sliding plates 718A and 718B, the two intermediate bearing parts 720A and 720B, and the lower bearing parts 716A and 716B. Furthermore, the two mutually inclined main sliding surfaces 722A and 722B can also absorb horizontal forces directed transversely to the movement axis A and transfer them accordingly between the two structural parts 712 and 714.

[0083] The ratio of absorbable vertical loads and horizontal forces transverse to the movement axis 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, in the service state of the structural support system 700, no gaping joint occurs in the region of the two main sliding surfaces 722A and 722B. The first angle α of the structural support system 700 is even selected such that, even in the ultimate limit state of the structural support system 700, no gaping joint occurs in the region of the two main sliding surfaces 722A and 722B. 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 less high horizontal forces, a more obtuse first angle α can be used, such as exactly 168 degrees.

[0084] Alternatively or additionally, the inclination of the first sliding plane 724A and the second sliding plane 724B can also be specified via their intersection angle relative to the horizontal H. Thus, both sliding planes 724A and 724B are inclined downwards relative 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 is 20 degrees here. However, if the horizontal force is less significant, a flatter second angle β can also be selected, such as 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 specifically absorb forces of different magnitudes from different directions (not shown).

[0085] Since the two sliding tilt bearings 710A and 710B in the structural support system 700 each have a separate sliding plate 718A and 718B, a simple height adjustment is also possible here using the corresponding bearing pair. The principle of the Fig. 8 shown height adjustment can be used, wherein the two sliding plates 718A and 718B each represent a sliding plate part 316A and 316B of the two-part sliding plate 316.

[0086] In the Fig. 13 A schematic side view of a building support system 700 according to the invention according to a second embodiment is shown. The building support system 700 of the second embodiment essentially corresponds to the building support system 700 of the first embodiment. The components, which have the same structure, will not be discussed further below.

[0087] The building support system 700 of the second embodiment differs from the building support system 700 of 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. In addition, the first sliding tilt bearing 710A has a lateral stop device 730A that limits 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 tilt bearing 710A that faces the movement axis A. For this purpose, the stop device 730A is formed in one piece and fastened 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 movement axis A.By means of an adjustment device, the lateral distance of the stop device 730A from the bearing base 716A and thus also from the sliding plate 718A can be adjusted. This is achieved here by a screw connection between the bearing base 716A and the stop device 730A.

[0088] Furthermore, the second sliding tilt bearing 710B has a lateral stop device 730B, which limits movement of the sliding plate 718B relative to the bearing base 716B. The stop device 730B is arranged on a side of the second sliding tilt bearing 710B that faces the movement axis A. For this purpose, the stop device 730B is formed in one piece and fastened to the bearing base 716B. In addition, the stop device 730B has a sliding device 732B in the form of a sliding strip, which guides the sliding plate 718B in a direction parallel to the movement axis A. By means of an adjusting device, the lateral distance of the stop device 730B from the bearing base 716B and thus also from the sliding plate 718B can be adjusted. This is also achieved here by a screw connection between the bearing base 716B and the stop device 730b.

[0089] If a moment M acts on the second structural part 714 in a clockwise direction about an axis parallel to the movement axis A, it is pulled against the stop device 730A of the first sliding tilt bearing 710A and is supported on the other side at the instantaneous center of rotation MP in the base of the second sliding tilt bearing 710B. As a result, a force F acts in the stop device 730A, counteracting the rotation of the second structural part 714. The same applies for a counterclockwise moment. In this case, the second structural part 714 is pulled against the stop device 730B of the second sliding tilt bearing 710B and is supported on the other side at the instantaneous center of rotation in the base of the first sliding tilt bearing 710A.

[0090] In this embodiment, both stop devices 730A and 730B are arranged on the vertically higher side of the corresponding sliding tilting bearing 710A and 710B. If the acting moments are small or negligible, the vertical force component of the dead weight acts primarily on the bearing relative to the operational load, whereby the stop devices 730A and 730B are completely force-free. Thus, with appropriate dimensioning, the stop devices 730A and 730B are only rarely activated, which is beneficial for their service life due to fatigue.

[0091] The Fig. 14 shows a schematic side view of a building support system 700 according to the invention according to a third embodiment. The building support system 700 of the third embodiment essentially corresponds to the building support system 700 of the second embodiment. The components, which have the same structure, will not be discussed further below.

[0092] The structural bearing system 700 of the third embodiment differs from the structural bearing system 700 of the second embodiment in that the first sliding bearing 710A and the second sliding bearing 710B are designed as elastomer bearings. For this purpose, the respective intermediate bearing parts 720A and 720B have an elastomer layer that provides corresponding deformation properties.

[0093] In the Fig. 15 A schematic plan view of a structural bearing system 800 according to a fourth embodiment of the invention is shown. The structural bearing system 800 has two bearing pairs 810 and 820 arranged along an axis B. Each bearing pair 810 and 820 has two plain bearings 810A, 810B, 820A, 820B. Thus, the first bearing pair 810 includes a first plain bearing 810A and a second plain bearing 810B. The second bearing pair 820 includes a first plain bearing 820A and a second plain bearing 820B.

[0094] The second structural part 714 is supported by the structural support system 800. The two bearing pairs 810 and 820 are arranged at the elongated ends of the second structural part 714, so that a single-span beam is formed. The first bearing pair 810 corresponds to the bearing pair of the structural support system 700 of the first embodiment, as shown in the Fig. 12 Here, the two main sliding surfaces, angled to each other, are arranged in such a way that the corresponding sliding planes form an upside-down gable roof.

[0095] The second bearing pair 820 also essentially corresponds to that of the first embodiment. Here, however, 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, 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 upside-down gable roof along the 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 the axis B allows torsional moments of the second structural part 714 to be absorbed particularly effectively.In a further embodiment, bearing pairs of the building storage system 700 of the second or third embodiment are used for the building storage system 800.

[0096] The Fig. 16 shows a schematic plan view of a building support system 900 according to the invention according to a fifth embodiment. The building 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 building part 914 consists of two single-span beams 914A, 914B. Both single-span beams 914A, 914B are arranged directly one after the other along the axis B. The individual single-span beams 914A, 914B could, for example, represent track sections, roadway sections or sections of a pipeline.

[0097] As before, the two single-span beams 914A, 914B are held at their elongated ends by the bearing pairs 910, 920, 930, and 940. Thus, the first single-span beam 914A is supported by the first bearing pair 910 and the second bearing pair 920. The second single-span beam 914B, on the other hand, is supported by the third bearing pair 930 and the fourth bearing pair 940.

[0098] All bearing pairs 910, 920, 930, 940 essentially correspond to the bearing pair of the structural support system 700 of the first embodiment. However, 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 upside-down gable roof for every second bearing pair along the axis B. 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 upside-down gable roof. Thus, the same arrangement of the main sliding surfaces or sliding planes is used in the region of the connection point of both single-span beams 914A, 914B.

[0099] The inclination of the main sliding surfaces of the first sliding tilt bearing 920A of the second bearing pair 920 and the first sliding tilt bearing 930A of the third bearing pair 930 are the same. Thus, the corresponding first angles 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 the second sliding tilt bearing 930B of the third bearing pair 930. This keeps a vertical offset in the area of the connection point between the two single-span beams 714A, 714B as small as possible in the event of transverse expansion in the structure.
