Definitions

  • the invention relates to a carriageway transition for expansion joints with several parallel to the joint edges on support members provided at bearing points, extending over the entire joint width, slidably and tilt-supported supported slats, the spacing of which is positively controlled, each slat having a slat foot with which it is attached to it brackets associated with a bearing support.
  • the object of the invention is to improve the generic roadway crossing in such a way that the number of slats that can be used for a given width of the expansion joint can be increased significantly without excessive edge pressures occurring at the bearing points between slats and support beams or that The value of the edge pressures can be significantly reduced with the same number of slats.
  • this is achieved in a carriageway transition of the type mentioned at the outset that at least two support beams are provided for each bearing location, adjacent slats not being supported on the same support beam but in each case on a different support beam that the width of a slat foot - seen in the direction of displacement of the slats - Is larger than the head width of this slat and that each slat foot with its laterally projecting area over the head width can be pushed under the body of the adjacent slat, ie it can slide under it.
  • the width of the bearing point in the slat foot is chosen to be as large as is necessary due to the desired or predetermined edge pressures, and this is completely independent of the (desired) head width of the slat.
  • the lateral deflection of the slat under consideration is no longer limited by the fact that it could run against the slat foot of the adjacent slat when it is deflected.
  • the place where, starting from a slat under consideration, the two adjacent slats are present in both deflection directions, is therefore very well available for the lateral deflection path of the slat under consideration.
  • the lateral protrusion of each slat foot is preferably selected to be at most half the head width of the slat, which makes it possible to push slats together until all slat heads rest against one another laterally.
  • each support beam has a rectangular cross section, that a sliding support between the slat foot and the support beam top and a with a between the slat foot and the support beam bottom
  • An elastomeric bearing provided with a sliding layer is preferably arranged, with a lateral support of the lamella base relative to the support carrier preferably also being provided via correspondingly laterally arranged sliding supports.
  • the sliding pads and / or the sliding layer are advantageously selected from polyamide or polytetrafluoroethylene or another suitable sliding material.
  • the support beams are received in each recess in recesses in the joint edges and horizontally fixed in one joint edge and horizontally movable in the other joint edge.
  • the invention makes it possible, according to the principle used in it, to carry out even the largest lamella constructions with positive control, without excessive edge pressures occurring or having to be accepted.
  • the roadway crossing according to the invention proves to be relatively simple overall in construction with moderate assembly effort, so that it stands out in addition to its other advantages also by pleasingly low costs.
  • the figures show a roadway transition 1, which is provided between two joint edges of a bridge structure, for example.
  • a suitable seal (not shown in FIG. 1), above which a road surface 2, for example concrete, is then formed, which forms a surface 3.
  • the structure of the carriageway transition 1 has lamellae 4 running within the expansion joint in the longitudinal direction of the joint and parallel to the joint edges, which are connected to one another via suitable elastic sealing bodies 5, the sealing bodies 5 each bridging the gap between the lamellae 4 in a watertight manner.
  • the edge lamellae are also positively connected to steel profiles 12 attached to the joint edges via such elastic sealing bodies 5.
  • Each lamella 4 consists of a lamella head 4 ', which has suitable profile receptacles for holding the sealing profiles 5 on its two edge sides.
  • a slat base 7 is formed for each slat 4, which can be mounted on suitable support bodies 8, 8 '(which will be described in detail below) each on a support bracket 9 or 9' (see. Fig. 3) in its Longitudinally supported.
  • FIG. 3 shows the top view of the carriageway transition from FIG. 1 from above, specifically in the area of a bearing point, the individual slats 4 being cut in the area of this bearing point, specifically there along the plane CC from FIG. 1.
  • the sectional plane DD 3 which in turn shows the sectional position of the section from FIG. 1.
  • the bearing point shown there has two support beams 9, 9 ', which extend across the entire joint width and are parallel to each other.
  • These support beams 9, 9 ' are, as shown in FIGS. 1 and 3, at the joint edges in each case in recesses 13 and 14, which are outside the joint gap, in the example shown the support beams 9, 91 on the left joint edge at 10 in are appropriately clamped horizontally, while they are movable in the horizontal direction at the other joint edge via suitable slide bearings 11.
  • Fig. 2 shows a section through a slat foot 7 along line A-A in Fig. 1, from which it can be seen first that the slat foot 7 completely grips or "clasped" the support beam 9, which in turn is rectangular in cross section.
  • a slider 8 made of a suitable material for example made of a PTFE or a polyamide plate, is initially arranged inside the slat base 7, via which the slat body 6 or the slat base 7 on the Top of the support bracket 9 is slidably mounted.
  • Similar sliding layers 19 are also provided laterally, as shown in FIG. 2, in order to also provide a suitable support against the side surfaces of the support beam 9.
  • the slider 8 ' Provided there has an elastomer bearing 16 in the support foot 7, which is provided on its top with a sliding layer 1 5 made of a suitable material, again from a PTFE or a polyamide layer.
  • the support bracket 9 is slidably mounted within the slat foot 7 in a suitable manner, so that when the support bracket 9 is completely gripped by the slat foot 7 in the longitudinal direction of the support bracket 9 in question, there is longitudinal displacement.
  • suitable flanges 17 are shown, which are provided with a suitable (in Fig. 2, not shown) clamping means can be braced against each other so that a desired bearing clearance or a desired bearing pressure can be reached within the bearing arrangement.
  • all other means suitable for the same purpose can be used for this purpose, as are known to the person skilled in the art and can be used or selected by him in a suitable manner in the formation of the lamella base 7.
  • each slat base 7 which essentially corresponds to the bearing width (each seen in the longitudinal direction of the support beam 9), is significantly larger than the width B of the slat head 4 ', the slat base 7 on both sides the slat 4 protrudes from the slat head 4 'predetermined width B by a length V.
  • This protruding portion of each slat foot 7 is, as shown in FIG. 1, designed such that its upper boundary surface is still below the lower boundary surface of the adjacent slat body 6. This makes it possible for the slat under consideration (for example the slat designated 4.1 in FIG.
  • each slat foot 7 is designed to be somewhat smaller than half the slat head width B.
