Definitions

  • the invention relates to a bearing device for supporting a first structural part on a second structural part, comprising a sleeve which can be anchored in or on the first structural part and a mandrel which can be anchored in or on the second structural part and which is used to receive a shaft caused by a relative movement of the structural parts in a transverse direction
  • the transverse force directed towards the mandrel is supported in the sleeve, the mandrel being displaceable in a longitudinal direction in the sleeve, according to the preamble of claim 1.
  • Expansion joints in a building are intentionally created joints that serve to interrupt larger structures in order to avoid the risk of cracks due to shrinkage, expansion, settlement or other, particularly thermally induced, changes.
  • Two building parts running in the same plane, usually concrete parts, which are separated from each other by such a joint, are often equipped with bearing devices, such as shear force mandrels, as connecting and pressure distribution elements.
  • bearing devices such as shear force mandrels
  • transverse force mandrels prevent a concrete part from sinking relative to the neighboring concrete part and, on the other hand, they accommodate linear expansion of the concrete parts through their movable mandrels.
  • the known bearing devices include a sleeve and a (transverse force) mandrel which can be displaced in the sleeve in the longitudinal direction of the sleeve.
  • the mandrel and the sleeve are anchored in the structural parts, preferably cast in concrete parts.
  • the structural parts can thus support each other in a transverse direction through the bearing device.
  • a balcony can be supported on a house wall against the acceleration of gravity, i.e. against the direction of gravity, using such a bearing device.
  • the bearing device can provide an additional degree of freedom provide a sliding bearing for the mandrel in the sleeve, so that the mandrel can be displaced in the lateral direction perpendicular to its longitudinal direction within the sleeve.
  • the mandrel rests directly on a wall of the sleeve. Since the structural parts cause high forces on the bearing device due to their masses, large forces act on the contact surface between the mandrel and the wall of the sleeve, which in turn lead to high tensions in the respective materials.
  • a balcony is made from a reinforced concrete slab or a steel structure, then it has a high dead weight, which must be supported against the direction of gravity by the wall and the mandrel.
  • the mandrel is usually provided with a circular cross section and the wall is designed as a surface or plane aligned perpendicular to the acting forces. If a cylindrical mandrel with a circular cross-section rests on such a plane, the common contact area is ideally just a line. If the transverse forces generated by the building parts act on this contact area, the materials in the area of the line are crushed, combined with high mechanical tension.
  • she teaches DE 10 2008 055 523 B3 a bearing device for forming a non-positive connection between a prefabricated reinforced concrete component and a second component.
  • the second component is equipped with a mandrel and a sleeve that is mounted essentially concentrically on the mandrel.
  • the prefabricated reinforced concrete component has a cladding tube for receiving the sleeve and the mandrel, the sleeve comprising a device for fixing the position of the mandrel.
  • the mandrel is fixed in the sleeve in the transverse and horizontal directions during the production of the concrete structural parts by chambers and their partitions.
  • the mandrel is mounted in lateral guides with radii of curvature. Although this deflects some of the forces from the transverse walls of the sleeve, such a mandrel no longer has a degree of freedom in the horizontal direction.
  • the entire structure has a complicated structure and is therefore difficult to manufacture and assemble.
  • the side guides fail, the mandrel acts with its full force on the walls of the sleeve. Therefore, this document cannot easily solve the problem of the short service life of the prior art bearing devices.
  • This storage device for supporting a floating stair landing on a fixed stairwell.
  • This storage device comprises a mandrel that can be anchored in the stairwell and a box-like housing that can be inserted into the stair landing, in the sleeve-like receptacle of which the mandrel is accommodated in a longitudinally displaceable manner.
  • the mandrel rests on a load distribution plate which covers an elastic plate lying on a bottom of the housing.
  • Vertical transverse forces occurring on the mandrel are introduced into the load distribution plate and into the elastic plate underneath via direct contact with it. The transverse force is distributed to a surface of the housing base located under the mandrel by the load distribution plate and the elastic plate, which together serve as a load distribution means.
  • the invention is based on the object of providing a simply constructed bearing device which, with corresponding cost advantages in production, has a high level of robustness against Hertzian pressures and thus an extended service life.
  • the object is achieved by a storage device with the features of claim 1 and by an arrangement consisting of such a storage device, a first structural part and a second structural part with the features of claim 20.
  • the bearing device according to the invention for supporting a first structural part on a second structural part comprises a sleeve anchored or anchorable in the first structural part and a mandrel anchored or anchorable in the second structural part.
  • the mandrel is mounted (in particular supported and/or clamped) in the sleeve to absorb a transverse force generated by the structural parts or their relative movement and directed transversely to the mandrel, ie effective in a transverse direction to the mandrel.
  • the mandrel can be displaced in the sleeve at least in a longitudinal direction and preferably also transversely (laterally).
  • a surface load distribution means within the sleeve, against which the mandrel rests for support in the transverse direction.
  • the transverse force is introduced into the surface load distribution means and distributed to the wall on a surface of the surface load distribution means that faces away from the mandrel and rests against a wall of the sleeve.
  • the transverse force can be distributed over an enlarged area and point or linear loading on the wall of the sleeve can be avoided. In this way, excessive Hertzian pressure and the resulting damage to the bearing device are avoided.
  • the surface load distribution means has a recess facing the mandrel in which the mandrel is mounted.
  • the mandrel can better carry the surface load distribution means during movements within the sleeve in a lateral direction, since a surface of the recess rests on the mandrel in the lateral direction.
  • the contact area can be increased compared to a simple line support with a plate-shaped load distribution means without a recess.
  • the recess is provided on a side of the surface load distribution means opposite the surface abutting the wall. The course of force between the sleeve and the mandrel goes via the recess through the surface load distribution means to the surface of the surface load distribution means resting on the wall of the sleeve.
  • the area of the surface load distribution means that rests on the wall is larger than a contact area that would arise if the mandrel were supported directly on the wall, as is the case in the prior art.
  • the area adjacent to a wall of the sleeve is larger than a contact area between the mandrel and the surface load distribution means. If the surface load distribution means were not provided in the sleeve, there would be a point or line-like contact surface between the mandrel and the wall, which would inevitably lead to damage to the wall.
  • the surface load distribution means distributes the transverse force on the surface, so that mechanical stress in the materials of the wall and the surface load distribution means is lower than when the mandrel comes into direct contact with the wall.
  • the mechanical tension is characterized by a force per unit area. If the transverse force is introduced via a contact surface between the mandrel and the surface load distribution means, which is, for example, linear or punctual, a high mechanical tension is formed between the surface load distribution means and the mandrel.
  • the surface load distribution means can be designed to be correspondingly robust and preferably has a greater material thickness in the transverse direction than the wall of the sleeve. In particular, the material thickness of the surface load distribution means in the area of the contact surface between the mandrel and the surface load distribution means is greater than a thickness of the wall.
  • the transverse force introduced via the contact surface is transmitted to the anchoring of the sleeve or the structural part via the surface of the surface load distribution means resting on a wall of the sleeve.
  • a reverse force progression is also conceivable, in which a force is directed via the surface to the robust surface load distribution means and via the contact surface to the mandrel. Regardless of the direction of the force progression, the wall is protected by the surface load distribution means.
  • the surface of the surface load distribution means can be directed downwards in the direction of gravity, ie in the direction of gravitational acceleration or gravity, in an assembled state of the bearing device. If a mandrel now rests on the surface load distribution means, a downward transverse force of the second structural part can be supported on the surface load distribution means. In such a case, the transverse direction is directed downwards in the direction of gravity. The transverse force is thus distributed over a wall arranged on the lower section of the sleeve (in the assembled state).
  • the surface load distribution means on a wall in an upper section of the sleeve with respect to the direction of gravity, so that the first structural part is supported on the mandrel via the sleeve.
  • the surface is directed upwards.
  • An arrangement at both the top and bottom is also possible to cover both installation situations.
  • the surface load distribution means rests with its surface on a lateral section of the sleeve with respect to the direction of gravity, so that forces that are oriented transversely to the direction of gravity are introduced into the surface load distribution means. The forces can act on the surface load distribution means via the mandrel and/or the sleeve. Due to these diverse possibilities, the surface load distribution means to arrange around the longitudinal direction of the mandrel, complicated building structures can be supported by the bearing device according to the invention.
  • small depressions are preferably arranged in the surface of the surface load distribution means and/or in the wall or wall surface on which the surface load distribution means rests.
  • “Small” in this context means that a dimension (depth and/or diameter) of the depressions is significantly smaller than a dimension of the surface(s) mentioned, for example by a factor of 10 to 100.
  • These depressions can be hemispherical or partially spherical, be cup-shaped or designed in another suitable manner. They can all be shaped in the same way or (partially) differently. They can be arranged evenly or irregularly.
  • the applicant's component tests have shown that such depressions on the surface between the sleeve wall and the load distribution element improve lubrication during sliding and thus in particular extend the service life of the components.
  • the sleeve has a rectangular cross section with a corresponding number of straight walls.
  • a straight wall of the sleeve is aligned horizontally with respect to the direction of gravity in an assembled state of the bearing device.
  • the surface of the surface load distribution means can rest against this wall and support the transverse force.
  • the horizontal wall can be arranged at the top or bottom in the direction of gravity.
  • the surface can rest against a straight wall that extends vertically along or parallel to the direction of gravity.
  • Such a vertical wall is arranged laterally in the sleeve.
  • the surface load distribution means can slide with the surface on the straight wall in a lateral direction. With a horizontal wall, the surface load distribution means can slide in the horizontal direction on the wall, while with a vertical wall, the surface load distribution means can slide vertically. In addition, sliding in the longitudinal direction of the mandrel is possible.
  • the storage device can also have more than one surface load distribution means.
  • the mandrel can be mounted in the recess so as to be displaceable in the longitudinal direction in order to provide a corresponding degree of freedom of expansion.
  • a special embodiment may include that the recess has a single contact surface, which preferably extends over the entire recess, with the recess in particular having a rounded or part-circular contour.
  • a single contact surface can therefore be achieved in particular if a cross section of the recess is formed with respect to the longitudinal direction of the sleeve, which has at least one round section. If the mandrel also has a cross section with, in particular, a round section, the round section of the mandrel can come into surface interaction in the round section of the surface load distribution means. As a result, the advantageous effect of a recess that takes along in the lateral direction is maintained and at the same time a contact surface that is significantly larger than the size of a line contact is formed.
  • the individual contact surface can extend over an entire width of the recess. It can be provided that the recess has a rounded or part-circular contour.
  • a particularly simply designed and yet very efficient surface load distribution means can contain a recess which is particularly U-shaped in cross section. Furthermore, the recess can have a section parallel to the surface on which the mandrel rests.
  • a further alternative embodiment can be designed by a recess with at least two contact surfaces between the mandrel and the surface load distribution means.
  • at least two sections of the cross section of the recess are inclined with respect to the transverse direction, so that the recess is preferably approximately V-shaped.
  • the mandrel lies against the inclined sections and forms contact surfaces.
  • three or more contact surfaces can be formed.
  • a section of the recess can be formed parallel to the surface resting on a wall of the sleeve, so that, for example, two sections of the recess that are inclined to the transverse direction rest on the mandrel, while the parallel section of the recess is positioned between the inclined sections.
  • the diverse design options for the recess offer the possibility of adapting the surface load distribution means to a wide variety of requirements.
  • the mandrel can be supported particularly gently if the surface load distribution means is prism-shaped or profile-like, with the recess extending in the longitudinal direction along the mandrel. This allows the entire mandrel to be stored in the recess.
  • the mandrel can protrude into the sleeve in particular to a length of approximately 30 cm. Furthermore, the mandrel can also be shorter or longer.
  • the contact surfaces within the recess can be interrupted along the longitudinal direction. For this purpose, depressions can be formed in the surface of the recess so that an area of the surface is spaced from the mandrel and has no contact with it. In this way, pockets can be formed in the surface of the recess.
  • the pockets may be filled with a lubricant such as grease, oil, copper, aluminum, graphite or other lubricant.
  • a lubricant such as grease, oil, copper, aluminum, graphite or other lubricant.
  • the lubricant facilitates a relative movement within the recess in the longitudinal direction of the mandrel to the surface load distribution means.
  • the surface load distribution means can have a width in a lateral direction, i.e. perpendicular to the transverse direction and perpendicular to the longitudinal direction, which is less than or equal to a dimension of the mandrel, especially its diameter, in this direction. As a result, movement of the mandrel with the surface load distribution means in the horizontal direction is not disturbed. Alternatively, the surface load distribution means can extend beyond the dimension of the mandrel in the stated direction, so that horizontal movement is restricted. The same applies to a surface distribution agent oriented in the vertical direction.
  • the surface load distribution means can be designed symmetrically with respect to the transverse direction. If the mandrel has a particularly circular cross section, an axis of symmetry of the mandrel can coincide with the axis of symmetry of the surface load distribution means. For example, when the surface load distribution means rests on a horizontal wall of the sleeve, an axis of symmetry can be aligned in the direction of gravity, with a vertical diameter of the mandrel aligned with the axis of symmetry of the surface load distribution means. This ensures a uniform force distribution from the mandrel into the surface load distribution means and finally to the sleeve.
  • both a sliding bearing of the mandrel in the recess and the surface of the surface load distribution means on the wall can be provided.
  • the mandrel is inserted into the recess without being connected to the surface load distribution means in a force-fitting or material-locking manner.
  • the surface of the surface load distribution means lies against the wall without being rigidly connected to it. This ensures a double possibility for moving the mandrel in the longitudinal direction.
  • a corresponding embodiment of the bearing device provides that the surface load distribution means is displaceable on the wall of the sleeve in the longitudinal direction and/or in a lateral direction, perpendicular to the transverse direction and perpendicular to the longitudinal direction.
  • the surface load distribution means on the wall can be displaceable in the lateral direction, while the mandrel in the recess is preferably not displaceable in the lateral direction.
  • Another alternative embodiment has a surface load distribution means rigidly connected to the wall. Then only the mandrel can be moved in the longitudinal direction of the sleeve.
  • the rigid connection between the surface load distribution means and the wall can be created by material bonding by welding, gluing or soldering or by force-fitting by screws or rivets.
  • the mandrel can be rigidly connected to the surface load distribution means.
  • a foot-like surface load distribution means that is firmly connected to the mandrel can rest on the wall and be mounted so that it can be displaced both in the longitudinal direction and in the lateral direction.
  • the surface load distribution means rigidly connected to the mandrel preferably projects radially from the mandrel. Such a surface load distribution means does not require a recess, the surface of which can be exposed to high mechanical stresses in the area of the contact surfaces with the mandrel.
  • the sleeve and/or the mandrel can be particularly useful to equip the sleeve and/or the mandrel with an anchor or anchor part, which can be anchored in the respective part of the building, for example embedded in concrete.
  • the anchor can also be connected to reinforcement of the structural part.
  • the sleeve can be stiffened by struts.
  • the sleeve and/or the mandrel can preferably be made of (galvanized) Steel or made of stainless steel or another suitable material (plastic, composite).
  • the mandrel can have a (circular) round or a square cross section.
  • the cross section can be circular or square or hexagonal (polygonal).
  • a bearing device consisting of a bearing device according to the invention, a first structural part and a second structural part
  • the sleeve is fastened or anchored in the first structural part and the mandrel is fastened or anchored in the second structural part in order to provide a transverse direction caused by relative movement of the structural parts absorb transverse force effective to the mandrel, the mandrel being displaceable in a longitudinal direction in the sleeve.
  • the sleeve and/or the mandrel are anchored with a respective anchor or anchor part in the respective structural part, preferably cast or concreted in, as mentioned above.
  • FIG 1 shows a conventional bearing device 10 in cross section in its assembled state.
  • the storage device 10 comprises an elongated sleeve 16 which has a rectangular cross section.
  • a bolt-shaped mandrel 18 with a circular cross section is arranged in the sleeve 16.
  • the sleeve 16 is in a first part of the building (in Figure 1 not shown) and the mandrel 18 is in a second part of the building (in Figure 1 not shown).
  • the two structural parts are supported on each other by the bearing device 10.
  • the bearing device 10 In the assembled state, the bearing device 10 is aligned in the manner shown relative to the direction of gravitational acceleration or the direction of gravity 4.
  • the mandrel 18 rests on a wall 26 of the sleeve 16 that is oriented in the lateral direction 3.
  • the lateral direction 3 is preferably horizontal and thus oriented transversely to the direction of gravity 4.
  • the mandrel 18 is mounted displaceably in the longitudinal direction 2 and in the lateral direction 3. Only in the transverse direction 1 is the mandrel 18 supported by the sleeve 16 or the corresponding structural part and cannot be moved. If an order is made in accordance with Figure 1 the mandrel 18 is thus supported in the transverse direction 1 against a transverse force Q effective downwards in the direction of the direction of gravity 4.
  • the wall 26 and a section of the surface of the mandrel 18 resting on the wall 26 form a contact surface 30 which absorbs the transverse force Q in the transverse direction 1.
  • the contact surface 30 is ideally not an extended surface, but merely a contact line.
  • the transverse force Q causes a pinch in the area of the contact line, so that a finite contact surface 30 is created.
  • the contact surface 30 has a relatively small extent based on the diameter D of the mandrel 18.
  • the small contact surface 30 creates a high mechanical stress in the material of the wall 26 in the area of the contact surface 30.
  • the mechanical stress results from the transverse force Q distributed over the contact surface 30. This results in damage 17 to the wall 26.
  • the wall 26 can be completely destroyed.
  • a storage device 10 according to the invention is in Figure 2 shown, wherein the bearing device 10 according to the invention is also anchored in a first and second structural part 12, 14.
  • the two structural parts 12, 14 are separated from each other by a joint 13 (expansion joint).
  • the joint 13 is bridged by the mandrel 18, which is anchored in the second structural part 14 by means of an anchor 32.
  • the mandrel 18 projects into the elongated sleeve 16 with a section protruding from the second structural part 14.
  • the sleeve 16 is also anchored in the first structural part 12 by means of an anchor 32.
  • the structural parts 12, 14 can be made of reinforced concrete. In the sleeve 16, the mandrel 18 rests on a surface load distribution means 20.
  • the surface load distribution means 20 has a recess 22 which is formed on a side of the surface load distribution means 20 that faces upwards in the direction of gravity 4. Due to the support of the mandrel 18, at least one contact surface 30 is formed between the mandrel 18 and the surface load distribution means 20 in the recess 22. On an opposite side of the surface load distribution means 20, ie pointing downward in the direction of gravity 4, a surface 24 is formed which rests movably on the wall 26 of the sleeve 16 in the longitudinal direction 2 and lateral direction 3.
  • the second structural part 14 is stored on or on the first structural part 12 by the storage device 10. The transverse force is directed downwards in the direction of gravity 4 and introduces a corresponding supporting or bearing force into the surface load distribution means 20.
  • the transverse force Q is transmitted to the wall 26 of the sleeve 16 via the surface load distribution means 20 and via the surface 24.
  • the transverse force Q is distributed over the entire surface 24, so that compared to the conventional bearing device 10 Figure 1 lower tension is generated in the wall 26. For example, no or only small Hertzian pressures occur because two relatively large, flat surfaces in the form of the surface 24 and the wall 26 interact.
  • the mandrel 18 can carry out a sliding movement 5 in the longitudinal direction 2, which changes the dimension of the joint 13 in the longitudinal direction 2.
  • the structural parts 12, 14 can move away from each other so that the mandrel 18 is pulled out of the sleeve 16, although a remaining part of the mandrel 18 always remains in the sleeve 16 and on the surface load distribution means 20.
  • the structural parts 12, 14 can move towards each other, whereby the mandrel 18 is pushed into the sleeve 16.
  • the surface 24 sliding on the wall 26 can also move the structural parts 12, 14 relative to one another in the lateral direction 3, with the mandrel 18 being displaced within the sleeve 16 parallel to a previous position.
