Definitions
- the present invention relates to a building sliding bearing for connecting a first and a second building part and a building mounting system with at least two sliding and tilting bearings for connecting at least two building parts.
- Generic structural sliding bearings usually have a lower bearing part that can be brought into connection with the first structural part, a sliding plate that can be brought into connection with a second structural part, and an intermediate bearing part that is arranged between the lower bearing part and the sliding plate.
- the main sliding surface of the structural bearing, along which the sliding plate can slide when the structural sliding bearing is in use, is generally arranged between the intermediate bearing part and the sliding plate.
- Structural sliding bearings of this type or also structural bearing systems for connecting a wide variety of structural parts are in principle sufficiently known from the prior art.
- Structural bearings for example, generally transfer vertical and horizontal loads and allow twisting and relative displacements where necessary.
- Structural plain bearings thus represent a special design of a structural bearing that is used in general for the defined and, if possible, constraint-free storage of any type of structure, such as bridges, in particular in road and rail traffic, girders and buildings of any type or parts thereof. They therefore enable relative movements between two parts of the structure in question, which can arise, for example, through the use of the structure or also through any external influences such as wind or an earthquake. With the use of such structural bearings or also corresponding structural bearing systems, damage to the corresponding structures can in particular be avoided.
- Structural bearings can be designed either as bearings that are fixed on all sides or that can be displaced on all sides or on one side.
- a guided bearing is converted into a fixed bearing by means of detents.
- the present invention relates in particular to uniaxially guided or unilaterally displaceable structural sliding bearings, in which thus a Displacement movement of the sliding plate along a certain axis direction of the main sliding surface is enabled.
- the fixed bearings that were subsequently converted are also relevant for the present invention.
- Such uniaxially guided structural plain bearings can be implemented, for example, as pot bearings or also spherical bearings. Both types of structural plain bearings are shown schematically in FIGS. 1 and 2 and are briefly explained below.
- the pot sliding bearing 10 has a pot 12 as a lower bearing part, 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 sliding bearing 10.
- the pot lid 20 closes the opening of the pot 12 and lies flush on the elastomer cushion 16 arranged below it.
- the sliding plate 22, which can be connected to a second structural part, is arranged above the pot lid 20.
- Both the pot lid 20 and the sliding plate 22 are aligned horizontally so that a horizontal main sliding surface 24 of the pot sliding bearing 10 extends between these two components.
- a sliding material 26 is arranged on the pot lid 20 in order to reduce the friction between the pot lid 20 and the sliding plate 22. This enables the sliding plate 22 to slide along the main sliding surface 24 with as little resistance as possible.
- the cup sliding 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 cup 12 below. At the same time, any rotations of the cup sliding bearing 10 are made possible by the elastomer cushion 16. This happens through selective yielding of the elastomer cushion 16 in the area of the force exerted by the pot lid 20.
- the inner seal 18 is arranged in such a way that the elastomer cushion 16 can be prevented from being pressed out through the gap between the pot wall and the pot lid 20 as soon as a pressure load is applied to the elastomer cushion 16 takes place. Furthermore, an outer seal can be arranged between the pot lid 20 and the pot 12, which keeps moisture and dirt away from the corresponding gap.
- the cup sliding bearing 10 has a central guide rail 28 in order to realize the uniaxial displaceability of the sliding plate 22.
- the middle guide rail 28 is arranged above the pot lid 20 in the area of the main sliding surface 24 and comes into engagement with a corresponding groove in the sliding plate 22.
- the guide rail 28 thus defines the axis of movement of the cup sliding bearing 10 in that it can absorb all horizontal forces transverse to the sliding direction.
- the two sliding surfaces between the guide rail 28 and the sliding plate 22 are arranged vertically along the axis of movement.
- horizontally acting forces strike the middle guide rail 28 perpendicularly from both sides and can thus be absorbed effectively.
- 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 and a movement of the sliding plate 22 along the axis of movement is facilitated.
- FIG. 2 shows a uniaxially guided structural sliding bearing in the form of a spherical bearing 110, as is known from the prior art.
- the spherical bearing 110 has a lower bearing part 112 which can be connected to a first part of the structure.
- the spherical cap bearing 110 also contains a spherical cap 114, which represents the intermediate bearing part of the spherical cap bearing 110.
- the spherical cap 114 is convexly curved downwards and is received in a correspondingly concave section on the upper side of the lower bearing part 112.
- a secondary sliding surface 116 or secondary sliding surface of the spherical bearing 110 is thus formed between the spherical cap 114 and the lower bearing part 112.
- a sliding material 118 is arranged in the area of the secondary sliding surface 116 in order to enable the spherical cap 114 to move with as little resistance as possible within the concave section of the lower bearing part 112.
- the sliding plate 120 which can be connected to a second part of the structure, rests above the dome.
- the horizontal main sliding surface 122 or primary sliding surface of the spherical bearing 110 is located between the dome 114 and the sliding plate 120.
- a sliding material 124 is arranged on the dome 114 in the area of the main sliding surface 122 in order to reduce the friction between the dome 114 and the sliding plate 120 .
- 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 114 and transfer them to the lower bearing part 112.
- the convex curvature of the spherical cap 144 and the receiving concave portion of the lower bearing part 112 enables corresponding rotations of the spherical cap 114 or of the spherical cap bearing 110. This happens here by sliding the spherical cap 114 along the secondary sliding surface 116.
- the uniaxial guidance of the spherical bearing 114 is implemented by two horizontally lateral guide rails 126. These are each arranged next to the main sliding surface 122 on the side of the lower bearing part 112 in order to come into engagement with the sliding plate 120.
- any horizontal forces are absorbed transversely to the two lateral guide rails 126 and the axis of movement of the spherical bearing 110 is thereby defined.
- the sliding surfaces between the two lateral guide rails 126 and the sliding plate 120 are each formed vertically along the axis of movement. As a result of the vertical action of the horizontal forces on the sliding surfaces of the two guide rails 126, it is also possible to effectively absorb higher forces.
- the two lateral guide rails 126 also 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 reduced considerably, whereby the movement of the sliding plate 120 along the axis of movement is correspondingly simplified.
- the state of use extends up to and including the limit state of usability. If this is exceeded, the specified conditions for the serviceability of a structure or component are no longer met. Limit states that affect the function of the structure or one of its parts under normal conditions of use or the well-being of the user or the appearance of the structure are also to be classified as the limit state of usability.
- any orientations of surfaces, axes and forces are described as horizontal or vertical, these are not restricted in relation to a horizontal or vertical plane or direction in the narrower sense.
- orientation details relate only to the plane of movement of the building sliding bearing or the building support system. This applies in particular when the structural sliding bearing or the structural bearing system is installed at an angle, for example.
- the orientation of the horizontal main sliding surface can differ from a horizontal plane in the narrower sense and can also be correspondingly inclined.
- uniaxially guided structural plain bearings with a central guide rail can only be used to a limited extent when absorbing very high forces.
- the rotation of the bearing about the vertical axis is hindered.
- the structural plain bearings described represent complex structures that require a correspondingly high level of effort in terms of installation space and the costs of manufacture and maintenance.
- the same disadvantages relate to structural support systems that have such structural sliding bearings.
- the structural sliding bearing according to the invention is thus characterized in that the main sliding surface has at least two partial sliding surfaces which are each arranged in sliding planes angled to one another, the sliding planes meeting in a common cutting line which forms an axis of movement of the structural sliding bearing along which the sliding plate can move. Furthermore, the two sliding planes enclose a first angle, the first angle being selected in such a way that, when the structural sliding bearing is in use, there is no gaping joint in the area of the main sliding surface. In other words, a structural sliding bearing is provided without a gaping joint in all sliding surfaces.
- the two mutually inclined partial sliding surfaces of the main sliding surface achieve a functional combination of vertical and horizontal force transfer within the structural sliding bearing. So now any vertical as well as transverse to the axis of movement can acting horizontal forces are absorbed by the main sliding surface of the structural plain bearing.
- the previously used centrally or laterally attached rail constructions are therefore no longer required, since their functions are fully fulfilled by the main sliding surface.
- the structure of the structural sliding bearing is considerably simplified and corresponding manufacturing costs can be reduced.
- the installation space that is sometimes only available to a limited extent can also be significantly reduced. In addition to omitting the rail constructions, this also applies to the corresponding design of the sliding plate.
- the relationship between the maximum possible vertical force and the horizontal force of the structural plain bearing can be optimally adjusted via the inclination of the two partial sliding surfaces to one another or the choice of the first angle.
- a gaping joint in the area of the main sliding surface when the structural sliding bearing is in use can be avoided even with maximum horizontal force in combination with the corresponding minimum vertical force.
- the structural sliding bearing is to be designed for higher horizontal loads
- the two inclined partial sliding surfaces are designed so steeply in relation to the horizontal forces that the sliding plate does not lift off the intermediate bearing part when the structural sliding bearing is in use.
- a sliding material with the lowest possible friction can be used in the area of the main sliding surface in order to nevertheless facilitate the movement of the sliding plate in the direction of the movement axis.
- the two partial sliding surfaces inclined towards one another result in continuous self-centering of the sliding plate on the intermediate bearing part of the structural sliding bearing in relation to the axis of movement.
- the sliding plate is thus optimally positioned in relation to the intermediate bearing part at all times and possible edge pressures along the axis of movement can be avoided.
- the main sliding surface preferably has exactly two, most preferably only two, partial sliding surfaces.
- the structural sliding bearing according to the invention is constructed as simply as possible.
- the two inclined partial sliding surfaces can, for example, form a coherent main sliding surface that is only appropriately bent once in the area of the movement axis.
- the two partial sliding surfaces inclined to one another also intersect along the axis of movement.
- the two inclined partial sliding surfaces can also be formed separately from one another in the respective sliding planes.
- the structural sliding bearing is preferably a uniaxially guided structural sliding bearing in which the sliding plate can only move along the axis of movement relative to the intermediate bearing part. This ensures that the structural sliding bearing does not allow any further movements of the sliding plate than those along the axis of movement with respect to the intermediate bearing part.
- the structural plain bearing can therefore be used in a targeted manner when horizontal movements are to be permitted in a single direction.
- the two sliding planes are preferably arranged in such a way that the cutting line runs horizontally.
- the axis of movement of the structural plain bearing thus also runs horizontally.
- the structural plain bearing is loaded as evenly as possible in terms of force transfer.
- the sliding plate can move smoothly with identical resistance in both directions of the axis of movement.
- the horizontal alignment is to be understood with reference to the plane of movement of the structural plain bearing.
- the cutting line can thus also have an orientation other than a horizontal line in the narrower sense.
- the first angle is advantageously selected in such a way that, in the limit state of the load-bearing capacity of the structural sliding bearing, there is no gaping joint in the area of the main sliding surface. If, based on the state of use, the loads on the structural plain bearing are further increased, the limit state of the load-bearing capacity occurs. According to the DIN EN 1990: 2010-12 standard for the principles of structural design, this state is related to collapse or other forms of structural failure.
- the limit states that affect the safety of persons and / or the safety of the structure are also to be classified as the ultimate limit state of the load-bearing capacity. This has the advantage that even in this state it is still ensured that there is no gaping joint in the area of the main sliding surface or that the sliding plate does not lift off from the intermediate bearing part.
- the main sliding surface has a permanently lubricated sliding material, preferably with PTFE, UHMWPE, POM and / or PA. Due to the permanently lubricated sliding material in the area of the main sliding surface, the friction between the sliding plate and the intermediate bearing part can be significantly reduced. Because of the at least two partial sliding surfaces inclined to one another, a sliding material with a low coefficient of friction can be used here. High horizontal forces can can already be taken up by a corresponding inclination of the inclined partial sliding surfaces. Thus, the sliding of the sliding plate along the axis of movement is facilitated.
- the sliding material preferably has a coefficient of friction which is a maximum of 0.03 for the rated value of the pressure in the sliding material.
- the sliding material advantageously has 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 over the sliding surface. The result is a particularly low-wear sliding material with a low coefficient of friction. Thus, the sliding movement of the sliding plate along the axis of movement is facilitated and the maintenance intervals of the structural sliding bearing are extended.
- At least two partial sliding surfaces angled to one another are arranged in such a way that the corresponding sliding planes form the shape of a gable roof.
- the gable roof is designed in such a way that the line of intersection or the axis of movement forms the roof ridge of the gable roof.
- the shape of a gable roof has the particular advantage that any accumulation of dirt and foreign bodies in the area of the at least two mutually inclined partial sliding surfaces can be largely avoided. This is particularly true in the area of the axis of movement, as this, as the roof ridge, represents the topmost point of the gable roof.
- At least two partial sliding surfaces angled to one another are preferably arranged in such a way that the corresponding sliding planes form the shape of an upside-down gable roof.
- the gable roof is designed in such a way that the line of intersection or the axis of movement forms the roof ridge of the gable roof. Due to the upside-down shape of the roof, it is possible to make the sliding plate stronger in the most heavily loaded center than on the edge, without requiring additional installation space in the vertical direction. In this way, installation space can be saved again despite the increased loads.
- At least two partial sliding surfaces angled relative to one another can be formed symmetrically to one another in relation to a plane of symmetry running through the cutting line in the vertical direction.
- the symmetrical arrangement of the at least two mutually inclined partial sliding surfaces improves self-centering of the sliding plate on the intermediate bearing part.
- the structural plain bearing has a simple structure and is therefore cost-effective to manufacture.
- the vertical direction is to be understood with reference to the plane of movement of the structural plain bearing.
- the vertical direction can also have a different orientation than a vertical in the narrower sense.
- At least two partial sliding surfaces of the main sliding surface are preferably designed to be of different sizes. This configuration is particularly advantageous when horizontal forces of different magnitudes act on the structural plain bearing from different directions.
- the structural sliding bearing according to the invention can be specially designed to be able to absorb greater forces acting from a certain horizontal direction transverse to the axis of movement than from a direction opposite thereto. In this way, the creation of a gaping joint or the lifting of the sliding plate can be ensured even when the force is unevenly applied.
- the two opening angles between the plane of symmetry and the respective inclined partial sliding surface could also have different sizes.
- At least one sliding plane is advantageously inclined downward with respect to the horizontal by a second angle between 0 degrees and 10 degrees, preferably by 6 degrees.
- a second angle between 0 degrees and 10 degrees, preferably by 6 degrees.
- the second angle corresponds at least to the friction that is permissible to be applied for the dimensioning.
- the first angle can be between 160 degrees and 180 degrees, preferably at 168 degrees. With a more acute first angle, correspondingly higher horizontal forces can be absorbed transversely to the movement axis by the respective inclined partial sliding surface. 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. Thus, on the one hand, a gaping joint or a lifting of the sliding plate from the intermediate bearing part is prevented. On the other hand, movement of the sliding plate along the axis of movement with as little resistance as possible is ensured.
- the sliding plate is preferably in several parts and the distance between the corresponding sliding plate parts is adjustable.
- the sliding plate is advantageously divided into two sliding plate parts.
- a sliding plate part is arranged in each case along one of the two partial sliding surfaces that are inclined relative to one another. Now the two sliding plate parts are transverse to the axis of movement synchronously along the If the corresponding sliding planes are pushed towards one another or apart, the horizontal distance between the two sliding plate parts and the lower part of the structural sliding bearing also changes.
- the position of the second structural part is tilted relative to the first structural part.
- the structural sliding bearing is designed as a pot bearing, in which the intermediate bearing part has a pot cover and the lower bearing part has a pot including an elastomer cushion.
- the structural plain bearing is designed as a spherical bearing in which the intermediate bearing part has a spherical cap.
- the cup has a convex section and the lower bearing part has a corresponding concave section, the convex section of the cup being slidably arranged in the concave section of the lower bearing part.
- effectively vertically acting forces are transmitted from the sliding plate to the lower part of the bearing by means of the spherical cap. Twists between the sliding plate and the lower bearing part are also made possible.
- the eccentricities from the acting horizontal force are significantly reduced.
- the sliding plate is made stronger at the most heavily stressed center than at the edge.
- the entire slide plate can be made thinner and thus produced more economically.
- the concave section of the lower bearing part preferably has a recess at a lower pole, so that in the region of the recess the convex section of the spherical cap does not come into contact with the concave section of the lower bearing part.
- the lowest point of the concave section of the lower bearing part is understood as the lower pole.
- the recess on the lower pole increases the radius of gyration and while the outer diameter remains the same, the pressure is increased by reducing the pressure surface, so that the friction and thus the torsional resistance, i.e. the acting torque, is reduced. This reduces the risk of gaping.
- the counteracting pressure from the acting vertical load increases compared to the pressure from the lifting horizontal force.
- This ratio can be controlled by the diameter of the recess.
- the structural sliding bearing can be individually adjusted and designed in combination with the at least two mutually inclined partial sliding surfaces of the main sliding surface.
- Both the choice of the first angle and the choice of the diameter of the recess offer the possibility of adapting the ratio of the vertical forces and horizontal forces that can be absorbed.
- the recess is preferably designed to be centered in a circle with respect to the lower pole. Due to this arrangement, a uniform influencing of the absorbable vertical forces and horizontal forces from different directions of action is achieved. Likewise, any acting forces are evenly transferred from the spherical cap to the lower part of the bearing. A recess in an elliptical shape with the corresponding displacement of the uniform force transfer would also be conceivable.
- a sliding material preferably a polymer sliding disk
- the recess is formed in the sliding material.
- the friction in the area of the secondary sliding surface of the spherical bearing can be reduced by the sliding material or the polymer sliding disk.
- the sliding material is basically in contact with the convex section of the spherical cap.
- the recess in the sliding material thus avoids such contact in this area with the spherical cap in order to achieve the advantages already discussed.
- the recess in the sliding material is also easy to produce.
- an annular polymer sliding disk can be used, which is attached to the concave section of the lower bearing part in the area of the secondary sliding surface.
- the structural sliding bearing expediently also has at least one stop between the sliding plate and the lower bearing part.
- the stop can be designed in any form in order to limit a movement of the sliding plate relative to the lower bearing part up to a predetermined extent.
- the structural plain bearing can also be converted into a fixed bearing. On the one hand, such a bearing has no play of movement transversely to the partial sliding surfaces that are inclined to one another. On the other hand, it has a low resistance to twisting.
- the structure support system comprises at least two slide bearings for connecting at least two structure parts.
- Each sliding bearing has a lower bearing part which can be brought into connection with a first structural part, a sliding plate which can be brought into connection with a second structural part, and an intermediate bearing part which is arranged between the lower bearing part and the sliding plate.
- At least one flat main sliding surface of the sliding bearing is arranged between the intermediate bearing part and the sliding plate.
- the structural support system is characterized in that the two sliding bearings form a pair of bearings 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 in a common line of intersection, which forms an axis of movement of the pair of bearings, along which the sliding plates can move.
- the advantages of the structural plain bearing according to the invention described above are achieved here with a corresponding structural bearing system.
- the two main sliding surfaces of the first sliding bearing and the second sliding bearing which are inclined towards one another, achieve a functional combination of vertical and horizontal force transfer within the pair of bearings and thus also of the entire structure support system. Any vertical or horizontal forces acting transversely to the axis of movement can now be absorbed by the main sliding surfaces of the first sliding bearing and the second sliding bearing. While the first slide bearing can absorb horizontal forces from only one specific direction transversely to the axis of movement, the horizontal forces from the opposite direction are absorbed by the second slide bearing.
- Both plain bearings thus complement each other in order to enable the functions and advantages of the previously described structural plain bearing as a structural bearing system.
- 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 in relation to the intermediate bearing parts of the two plain bearings at all times and possible edge pressures along the axis of movement can be avoided.
- Such an arrangement is therefore particularly advantageous in the construction of bridges for the routes of high-speed trains. It is essential to avoid a corresponding lateral misalignment here.
- the two separate slide plates of the two slide bearings With the two separate slide plates of the two slide bearings, a simple height adjustment is also provided. In particular, it is made possible to adjust the distance between the two sliding plates and the respective lower bearing parts. The distance between changed the two parts of the building. If the two sliding plates are pushed towards or apart from one another in a synchronous manner along the corresponding sliding planes transversely to the axis of movement, the horizontal distance between the two sliding plates and the respective lower parts of the two sliding bearings also changes. If, on the other hand, only one of the two sliding plates is shifted in this way, for example, or if the two sliding plates are also shifted non-synchronously, the position of the second structural part is tilted relative to the first structural part. Alternatively, the two sliding plates can also be designed in one piece.
- the horizontal is to be understood with reference to the plane of movement of the building support system. So the horizontal can also have a different orientation than a horizontal plane in the narrower sense.
- the at least two slide bearings are advantageously designed as slide and tilt bearings.
- spherical bearings that bring the advantages described above would be conceivable.
- the at least two slide bearings can be designed as elastomer bearings. In addition to their sliding properties, these also have deformation properties in the intermediate bearing part, as a result of which twisting and punctual loads can be compensated particularly effectively.
- the first sliding plane and the second sliding plane expediently enclose a first angle, the first angle being selected such that no gaping joint arises in the area of the main sliding surfaces when the structural support system is in use.
- the ratio between the maximum possible vertical force and horizontal force of the building support system can be set via the inclination of the two main sliding surfaces to one another or the choice of the first angle. Without having to adjust the dimensions of the individual main sliding surfaces. With the appropriate choice of the inclination of the two main sliding surfaces to each other, a gaping joint in the area of the main sliding surfaces when the structure support system is in use can be avoided even with maximum horizontal force in combination with the corresponding minimum vertical force.
- the two inclined main sliding surfaces are designed so steeply against the respective horizontal force that a gaping joint or lifting of the sliding plates from the respective intermediate bearing parts does not occur when the structure support system is in use.
- a sliding material with the lowest possible friction can be used in the area of the main sliding surfaces in order to nevertheless facilitate the movement of the sliding plates in the direction of the movement axis as much as possible.
- the pair of bearings is preferably a uniaxially guided pair of bearings 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 move the sliding plates further than which allows along the axis of movement with respect to the intermediate bearing parts.
- the structure support system can therefore be used in a targeted manner when horizontal movements are to be permitted in a single direction.
- the first slip plane and the second slip plane are arranged in such a way that the cutting line runs horizontally.
- the axis of movement of the pair of bearings also runs horizontally.
- the pair of bearings is evenly loaded in terms of force transfer.
- the sliding plates can move evenly with identical resistance in both directions of the axis of movement.
- the horizontal alignment is to be understood with reference to the plane of movement of the building support system.
- the cutting line can thus also have an orientation other than a horizontal line in the narrower sense.
- the first angle is advantageously selected in such a way that, in the limit state of the load-bearing capacity of the building support system, there is no gaping joint in the area of the main sliding surfaces. If, starting from the state of use, the loads on the structural support system are further increased, the limit state of the load-bearing capacity occurs. According to the DIN EN 1990: 2010-12 standard for the principles of structural design, this state is related to collapse or other forms of structural failure.
- the limit states that affect the safety of persons and / or the safety of the structure are also to be classified as the ultimate limit state of the load-bearing capacity. Thus, even in this state, it is ensured that no gaping joint arises in the area of the main sliding surfaces or that the sliding plate does not lift off the intermediate bearing part.
- At least one main sliding surface expediently has a permanently lubricated sliding material, preferably with PTFE UHMWPE, POM and / or PA. Due to the permanently lubricated sliding material in the area of the main sliding surface, the friction between the sliding plate and the intermediate bearing part can be significantly reduced. Due to the inclined main sliding surfaces, a sliding material with a low coefficient of friction can be used here. High horizontal forces can already be absorbed by a corresponding inclination of the main sliding surfaces. Thus, the sliding of the sliding plate along the axis of movement is facilitated.
- the sliding material preferably has a coefficient of friction which is a maximum of 0.03 for the rated value of the pressure in the sliding material.
- the sliding material preferably has 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 over the sliding surface. The result is a particularly low-wear sliding material with a low coefficient of friction.
- at least two main sliding surfaces angled to one another are arranged in such a way that the corresponding sliding planes form the shape of a gable roof.
- the gable roof is designed in such a way that the line of intersection or the axis of movement forms the roof ridge of the gable roof.
- the shape of a gable roof has the particular advantage that any accumulation of dirt and foreign bodies in the area of the main sliding surfaces can be largely avoided. This applies in particular in the area of the movement axis for the case when the first and second slide bearings are installed in the immediate vicinity, since the movement axis as the roof ridge represents the topmost point of the gable roof.
- At least two main sliding surfaces angled to one another are arranged in such a way that the corresponding sliding planes form the shape of an upside-down gable roof.
- the gable roof is designed in such a way that the line of intersection or the axis of movement forms the roof ridge of the gable roof. Due to the upside-down roof shape, it is possible to make the respective sliding plate stronger at the end towards the axis of movement without requiring additional installation space in the vertical direction. In this way, installation space can be saved again despite the increased loads.
- At least two main sliding surfaces angled to one another are designed symmetrically to one another in relation to a plane of symmetry running through the cutting line in the vertical direction.
- the arrangement according to the invention enables improved self-centering of the system made up of the two sliding plates and the connected structure relative to the axis of movement defined by the two sliding bearings.
- the structure support system is simple and therefore cost-effective to manufacture.
- the vertical direction is to be understood with reference to the plane of movement of the building support system.
- the vertical direction can also have a different orientation than a vertical in the narrower sense.
- At least two main sliding surfaces angled to one another are designed to be of different sizes.
- This configuration is particularly advantageous when horizontal forces of different magnitudes act on the building support system from different directions.
- the structure support system according to the invention can be specially designed to be able to absorb greater forces acting from a certain horizontal direction transverse to the axis of movement than from a direction opposite thereto. In this way, the creation of a gaping joint or the lifting of the sliding plate can be ensured even when the force is unevenly applied.
- At least one sliding plane is expediently inclined downward relative to the horizontal by a second angle between 0 degrees and 10 degrees, preferably by 6 degrees.
- the horizontal is to be understood with reference to the plane of movement of the building support system. So the horizontal can also have a different orientation than a horizontal plane in the narrower sense.
- the second angle corresponds at least to the friction that is permissible to be applied for the dimensioning.
- the first angle is preferably between 160 degrees and 180 degrees, preferably 168 degrees. With a more acute first angle, correspondingly higher horizontal forces can be absorbed transversely to the axis of movement by the respective inclined main sliding surfaces. 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. Thus, on the one hand, a gaping joint or a lifting of the sliding plate from the intermediate bearing part is prevented. On the other hand, movement of the sliding plate along the axis of movement with as little resistance as possible is ensured.
- the first slide bearing and / or the second slide bearing has a preferably lateral stop device which limits a movement of the slide plate with respect to the lower part of the bearing. A rotation of the second structural part with respect to the first structural part is thus counteracted.
- the stop device is preferably designed in such a way that a moment acting on the second structural part is supported about an axis parallel to the axis of movement.
- the stop device can, for example, be designed as a one-piece stop or also in several parts. In one example, the stop device is attached to the bearing base.
- the stop device is advantageously arranged on a side of the respective slide bearing that faces or is inclined towards the axis of movement. With this arrangement, moments can be absorbed in a targeted manner, which act on the second structural part about an axis parallel to the axis of movement.
- the stop device is preferably arranged on the side of the sliding bearing that is higher in the vertical direction. This has the advantage that with small or negligible torques it is mainly the vertical force component of the dead weight that acts on the bearing with regard to the operational load.
- the stop device is completely free of force. This significantly reduces the wear on the stop device and increases its service life.
- the stop device expediently has an adjusting device in order to set a position of the stop device.
- the stop device can be optimally and precisely set in relation to the individual components of the plain bearing, depending on the situation.
- the adjustment device can be implemented, for example, via a screw connection. It is also conceivable that the setting device has an electric motor in order to set the position of the stop device particularly precisely and / or automatically.
- the stop device preferably has a sliding device which guides the sliding plate in a direction parallel to the axis of movement. Due to the sliding device, the stop device enables movement of the sliding plate with as little friction as possible relative to the lower bearing part along the movement axis, despite the movement-restricting function towards or away from the movement axis.
- the sliding device is designed as a sliding strip.
- the building support system advantageously has at least two pairs of bearings and an axle.
- the pairs of bearings are arranged one after the other along the axis, the angled main sliding surfaces being arranged in such a way that the corresponding sliding planes of the pairs of bearings alternately form the shape of a gable roof and the shape of an upside-down gable roof along the axis.
- the axis can preferably be designed in a straight line.
- a curved axis would also be conceivable, as can be the case, for example, with a roadway, a track section or a pipeline. Due to the alternating arrangement of the main equal surfaces, possible torsional moments of the structure can be absorbed in a targeted manner.
- the building support system preferably has at least two pairs of bearings and an axle.
- the pairs of bearings are arranged one after the other along the axis, the angled main sliding surfaces being arranged in such a way that the corresponding sliding planes of the pairs of bearings alternately form the shape of a gable roof and the shape of an upside-down gable roof for every second pair of bearings along the axis.
- the axis can preferably be designed in a straight line.
- a curved axis would also be conceivable, as can be the case, for example, with a roadway, a track section or a pipeline. This principle can be used in particular when several single-span girders are supported one behind the other along the axis by the building support system.
- one end of a single-span girder is held by a pair of bearings.
- a constant arrangement of the main sliding surfaces of both bearing pairs is used in the connection points between the single-span girders.
- the inclination of the main sliding surfaces in the case of two successive sliding bearings along the axis in the area of such a connection point is also preferably identical. This can further reduce the risk of a height offset.
- the structural sliding bearing and structural bearing system according to the invention is thus constructed as simply as possible and at the same time can work for a long time without maintenance and reliably with increased force. The cost and effort involved in manufacturing and operating the
- Structural plain bearings and the structural bearing system are thereby reduced.

- the structural sliding bearing 210 is designed in the form of a uniaxially guided spherical bearing and has a bearing lower part 212, which can be connected to a first structural part, a spherical bearing intermediate part 214 and a sliding plate 216, which can be connected to a second structural part, for transferring force.
- the lower bearing part 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 lower bearing part 212.
- the friction between the convex section 220 of the spherical cap and the concave section 218 of the lower bearing part 212 can be reduced.
- the movement of the spherical cap relative to the lower bearing part 212 is thus facilitated and the structural sliding bearing 210 enables a rotation about the vertical and horizontal axis.
- the sliding plate 216 rests on the dome in a slidable manner in order to be connected to the second structural part above.
- the main sliding surface 226 of the structural sliding bearing 210 is thus arranged between the spherical cap and the sliding plate 216.
- 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 sliding planes 230A and 230B which are angled to one another and meet in a common horizontal line of intersection S.
- the line of intersection S forms the axis of movement A of the structural sliding bearing 210, along which the sliding plate 216 can move. Corresponding displacements of the first structural part relative to the second structural part can thus be permitted.
- the two partial sliding surfaces 228A and 228B which are inclined relative to one another, are arranged in such a way that the corresponding sliding planes 230A and 230B form the shape of a gable roof.
- the shape of an upside-down gable roof would also be conceivable here, with the movement axis A forming the ridge of the gable roof in each case.
- the two partial sliding surfaces 228A and 228B, which are inclined relative to one another are of the same size and are symmetrical to one another in relation to a plane of symmetry E running through the cutting line S in the vertical direction.
- the two partial sliding surfaces 228A and 228B, which are inclined relative to one another could also have different sizes (not shown).
- the main sliding surface 226 has a sliding material 232 in order to reduce the friction between the spherical cap and the sliding plate 216.
- each of the two partial sliding surfaces 228A and 228B which are inclined relative to one another, has a permanently lubricated polymer sliding disk, each of which is attached in a recess 234 on the spherical cap.
- the polymer sliding washer is made of PTFE, UHMWPE, POM and / or PA and has prefabricated lubrication pockets in which the lubricant can be stored and distributed evenly over the entire contact surface.
- the sliding material 232 has a very low coefficient of friction and is particularly wear-resistant when it is used. In the present embodiment, the coefficient of friction is a maximum of 0.03.
- the structural sliding bearing 210 can absorb vertically acting forces via the two partial sliding surfaces 228A and 228B, which are inclined relative to one another, and transfer them from the second structural part to the first structural part.
- vertically acting forces are thus introduced from the second structural part into the first structural part via the sliding plate 216, the spherical cap and the lower bearing part 212.
- horizontal forces directed transversely to the axis of movement A can also be absorbed by the two mutually inclined partial sliding surfaces 228A and 228B and correspondingly transmitted between the two structural parts.
- the ratio of absorbable vertical loads and horizontal forces transverse 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. Both sliding planes 230A and 230B therefore enclose a first angle ⁇ , which is selected such that, in the state of use, the structural sliding bearing 210 no gaping joint arises in the area of the main sliding surface 226.
- the first angle a of the structural sliding bearing 210 is even selected in such a way that even in the limit state of the load-bearing capacity of the structural sliding bearing 210, there is no gaping joint in the area of the main sliding surface 226.
- the structural sliding bearing 210 shown in FIGS. 3 to 7 has a first angle of 168 degrees. However, if the structural plain bearing 210 is to be designed for very high horizontal forces, a more pointed first angle a can also be used.
- both sliding planes 230A and 230B can also be specified via their intersection angle with respect to the horizontal H.
- both sliding planes 230A and 230B are inclined downwards by a second angle ⁇ relative to the horizontal H.
- both sliding planes 230A and 230B of the structural sliding bearing 210 have the same second angle ⁇ , which is 6 degrees. In the case of very high horizontal forces, however, a particularly steep angle can also be selected. It would also be possible for the sliding plane 230A to have a different second angle ⁇ than the sliding plane 230B in order to specifically absorb different force effects from different directions (not shown).
- FIG. 8 shows a sequence of two schematic cross-sectional representations of a structural sliding bearing 310 according to a second embodiment, with which a height adjustment of the structural sliding bearing is illustrated.
- the structural sliding bearing 310 corresponds essentially to the structural sliding bearing 210 of the first embodiment.
- the identical components are not discussed further below.
- the structural sliding bearing 310 differs from the structural sliding bearing 210 of the first embodiment in that the sliding plate 316 is constructed in several parts and the distance between the corresponding sliding plate parts 316A and 316B is adjustable.
- the sliding plate 316 is only divided into two halves, so that the sliding plate 316 is formed by two sliding plate parts 316A and 316B of identical size.
- the two sliding plate parts 316A and 316B are each arranged along one of the two partial sliding surfaces 228A and 228B, which are inclined relative to one another, in order to enable a horizontal connection of the second structural part.
- an end state of the structural sliding bearing 310 is shown after the two sliding plate parts 316A and 316B have been correspondingly pushed towards one another.
- the horizontal first distance d1 between the two sliding plate parts 316A and 316B has decreased to the horizontal second distance d2.
- both sliding plate parts 316A and 316B still each have the same horizontal distance from the axis of movement A.
- the first total height G1 is increased accordingly by the height difference DH 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 correspondingly reduced.

- the structural sliding bearing 310 corresponds essentially to the structural sliding bearing 210 of the first embodiment.
- the identical components are not discussed further below.
- the structural sliding bearing 410 differs from the structural sliding bearing 210 of the first embodiment in that the concave section 418 of the lower bearing part 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 dome does not match the concave section 418 of the lower bearing part 412 comes into contact.
- this recess 436 is formed in the polymer sliding disk of the sliding material 424 in the area of the secondary sliding surface 422.
- the recess 436 has a circular shape that is centered on the lower pole P.
- the radius of gyration is increased.
- the counteracting pressure from the acting 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.
- the structural plain bearing 410 with the recess 436 offers a further setting option for adapting the relationship between the vertical forces that can be absorbed and the horizontal forces.
- the choice of the inclination of the two mutually inclined partial sliding surfaces 228A and 228B can thus be matched to the diameter D of the recess 436 in order to optimally design the structural sliding bearing 410 for the most varied of forces.
- FIG. 10 shows a schematic exploded drawing of a structural sliding bearing 510 according to the invention according to an advantageous fourth embodiment. That Structural sliding bearing 510 essentially corresponds to structural sliding bearing 210 of the first embodiment. The identical components are not discussed further below.
- 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 each attached to the slide plate 538 centrally, laterally and opposite one another. Both stops 538 protrude in the direction of the lower bearing part 212, so that the stops 538 are arranged between the lower bearing part 212 and the sliding plate 516. The movement of the sliding plate 516 with respect to the lower bearing part 212 is thus limited.
- the stops 538 are designed in such a way that the structural sliding bearing 510 is converted into a fixed bearing.
- FIG. 11 shows a perspective view of a structural sliding bearing 610 according to the invention in accordance with an advantageous fifth embodiment.

- the lower bearing part 612 has a pot together with an elastomer cushion 640 in order to enable minor rotations or displacements of the pot lid arranged above it and thus of the pot bearing. All the advantages of the main sliding surface discussed apply accordingly.
- FIG. 12 shows a schematic side view of a building support system 700 according to the invention in accordance with a first embodiment.
- the building support system 700 thus has a first sliding bearing 710A and a second sliding bearing 710B in order to connect a first structural part 712 to a second structural part 714.
- the first slide bearing 710A and the second slide bearing 71OB are each designed as slide and tilt bearings.

- the second Gleitkipplager 710B also has a bearing lower part 716B, which can be brought into connection with the first structural part 712, a sliding plate 718B, which can be brought into connection with the second structural part 714, and an intermediate bearing part 720B or a tilting part, which between the lower bearing part 716B and the sliding plate 718B is arranged.
- a planar main sliding surface 722B of the second sliding / tilting bearing 71 OB also extends here between the intermediate bearing part 720B and the sliding plate 718B.
- Both slide and tilt bearings 71 OA and 71 OB form a uniaxially guided pair of bearings, in which the main slide surface 722A of the first slide and tilt bearing 71 OA is arranged in a first slide plane 724A inclined to the horizontal H.
- the main sliding surface 722B of the second sliding tilting bearing 71 OB 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 section 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. Corresponding displacements of the first structural part 712 with respect to the second structural part 714 can thus be permitted.
- the two inclined main sliding surfaces 722A and 722B are arranged in such a way 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 would also be conceivable here, with the axis of movement A forming the ridge of the gable roof in each case.

- the special arrangement of the two main sliding surfaces 722A and 722B also enables a functional combination of the vertical and horizontal force transfer within the bearing pair. So the pair of bearings can on the one hand vertically acting forces via the two inclined main sliding surfaces 722A and 722B and transferred 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.
- horizontal forces directed transversely to the axis of movement A can also be absorbed by the two main sliding surfaces 722A and 722B, which are inclined relative to one another, and correspondingly transmitted between the two structural parts 712 and 714.
- 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 the first sliding plane 724A and the second sliding plane 724B. Both sliding planes 724A and 724B therefore enclose a first angle ⁇ , which is selected such that when the building support system 700 is in use, no gaping joint arises in the area of the two main sliding surfaces 722A and 722B.
- the first angle a of the building support system 700 is even selected in such a way that even in the limit state of the load-bearing capacity of the building support system 700 there is no gaping joint in the area of the two main sliding surfaces 722A and 722B.
- the structural support system 700 shown has a first angle a of 140 degrees. However, if the structural sliding bearing 700 is to be designed for less high horizontal forces, a more obtuse first angle a can also be used, for example between 160 degrees and 180 degrees or exactly 168 degrees.
- both sliding planes 724A and 724B are inclined downward by a second angle ⁇ relative to the horizontal H.
- both sliding planes 724A and 724B of the building support system 700 have the same second angle ⁇ , which here is 20 degrees.
- a flatter second angle ⁇ can also be selected, for example 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 ⁇ than the sliding plane 724B in order to specifically absorb different force effects from different directions (not shown).
- FIG. 8 shows a schematic side view of a building support system 700 according to the invention according to a second embodiment.
- the structure support system 700 of the second embodiment corresponds essentially to the structure support system 700 of the first embodiment. The components with the same structure are not discussed further below.
- the structure support system 700 of the second embodiment differs from the structure 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.

- the stop device 730A is formed in one piece and is attached to the lower bearing part 716A.
- the stop device 730A has a sliding device 732A in the form of a sliding strip, which 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 lower bearing part 716A and thus also from the slide plate 718A can be adjusted by means of an adjusting device. This is achieved here by a screw connection between the lower bearing part 716A and the stop device 730A.
- the second slide and tilt bearing 71 OB has a lateral stop device 730B which limits a movement of the slide plate 718B with respect to the lower bearing part 716B.
- the stop device 730B is arranged on a side of the second slide and tilting bearing 71 OB that faces the axis of movement A.
- the stop device 730B is formed in one piece and attached to the bearing lower part 716B.
- 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 axis of movement A.
- the lateral distance of the stop device 730B from the lower bearing part 716B and thus also from the slide plate 718B can be adjusted by means of an adjusting device. This is also achieved here by means of a screw connection between the lower bearing part 716b and the stop device 730b.
- a moment M acts on the second structural part 714 around an axis parallel to the movement axis A clockwise, it is pulled against the stop device 730A of the first sliding tilting bearing 71OA and is supported on the other side at the momentary pole MP in the base of the second sliding tilting bearing 71OB .
- a force F acts in the stop device 730A which counteracts the rotation of the second structural part 714.
- the second structural part 714 is pulled against the stop device 730B of the second slide and tilt bearing 710B and is supported on the other side at the moment in the base of the first slide and tilting bearing 710A.
- both stop devices 730A and 730B are arranged on the side of the corresponding slide and tilt bearing 71 OA and 71 OB which is higher in the vertical direction. If the acting moments are small or negligible, it is mainly the vertical force component of the dead weight that acts on the bearing with regard to the operational load, so that the stop devices 730A and 730B are completely free of forces.
- the stop devices 730A and 730B are therefore only rarely activated if they are appropriately dimensioned, which is beneficial for the service life as a result of fatigue.

- the first pair of bearings 810 corresponds to the pair of bearings of the building support system 700 of the first embodiment, as is shown in FIG. 12. So 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.
- the second pair of bearings 820 also essentially corresponds to that of the first embodiment.
- the two main sliding surfaces, which are angled to one another are arranged in such a way that the corresponding sliding planes form the shape of a normal gable roof.

- the second structural part 914 consists of two single-span girders 914A, 914B.
- Both single-span supports 914A, 914B are arranged directly one after the other along the B axis.
- the individual single-span girders 914A, 914B could, for example, represent pieces of track, pieces of roadway or sections of a pipeline.
- the two single-span supports 914A, 914B are held at their elongated ends by the bearing pairs 910, 920, 930, 940.
- the first single-span carrier 914A is supported by the first pair of bearings 910 and the second pair of bearings 920.
- the second single-span carrier 914B is supported by the third pair of bearings 930 and the fourth pair of bearings 940.
- All bearing pairs 910, 920, 930, 940 essentially correspond to the bearing pair of the building support system 700 of the first embodiment.
- the mutually inclined main sliding surfaces are arranged in such a way 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.
- the two sliding planes of the first pair of bearings 910 and of the fourth pair of bearings 940 have the shape of a gable roof.
- the two sliding planes of the second pair of bearings 920 and of the third pair of bearings 930 are designed in the form of an upside-down gable roof.
- the same arrangement of the main sliding surfaces or the sliding planes is used in the area of the connection point of both single-span supports 914A, 914B.
- the inclination of the main sliding surfaces of the first slide and tilt bearing 920A of the second pair of bearings 920 and of the first slide and tilting bearing 930A of the third pair of bearings 930 are the same.
- the corresponding first angle and second angle are thus also identical here.
- the area of the connection point between the two single-span girders 714A, 714B is kept as small as possible.
- bearing pairs of the building support system 700 of the second or third embodiment are used for the building support system 900.
