Definitions

  • the present invention relates to a bridging device for expansion joints in carriageways of bridges or the like with elastic sealing strips which run transversely to the longitudinal direction of the carriageway and are each fitted between supports which run parallel to one another, the upper side of which is flush with the carriageway surface, and each with a Crossbars are connected, the latter being grouped together and mounted longitudinally displaceably in niches located below the carriageway on both sides of the joint gap, the longitudinal displacement of the crossbars being effected by means of a handlebar, the ends of which are held on opposite sides of the joint gap.
  • Such a bridging device for expansion joints with a so-called forced control of the trusses is known from CH-PS 494 316.
  • the handlebar is arranged under the trusses.
  • Each traverse is provided with a downwardly projecting pin which engages in a longitudinal groove in the handlebar with the interposition of a sliding block.
  • the handlebars located deep below the surface of the road must move the crossbeams with the girder resting on them up to the road surface.
  • the invention has for its object to provide a positive control for a bridging device of the type mentioned, in which the power transmission from the crossbars to the handlebars via as few bearing parts and with the smallest possible lever arm.
  • the joint gap F which is variable in the width direction due to the dilatation movement of the components B1, B2, usually runs perpendicular to the longitudinal direction of the carriageway.
  • the bridging device of the carriageway is shown in a position which corresponds exactly to a central position between the maximum and minimum joint width.
  • Groups of trusses 1 are arranged at certain intervals along the entire length of the joint.
  • the number of crossbars 1 per group corresponds exactly to the number of beams 2 running perpendicular to the crossbars 1 and in the longitudinal direction of the joint.
  • the beams extend over the entire length of the joint gap, crossing over several groups of crossbars.
  • Each carrier 2 is firmly connected, preferably welded, to a cross member 1 of the group assigned to it.
  • the traverses 1 crossing the joint gap F project into niches N provided on both sides of the joint.
  • the two ends of the link 4 are held by means of struts 3 on opposite sides of the joint gap.
  • the drawing shows an average width expansion of the joint gap, in which the link runs exactly in the longitudinal direction of the joint. If the joint becomes narrower due to expansion of the components or wider due to contraction of the components, the handlebar swivels and ensures that all the gaps between the beams, which are bridged by elastic sealing strips, all widen or narrow equally.
  • the handlebar 4 passes through all the traverses 1 of a group. In the crossbeams 1, the handlebar 4 is guided in specially designed bearings 10, 40.
  • the cross members 1 are slidably mounted on a support strip 6 provided in the niche N.
  • These support strips 6 are preferably made of tetrafluoroethylene, which can be provided with lubricant pockets.
  • the beams 2 are each firmly connected to only one cross member 1 of the group and cross the other cross members of this group with play as can be seen in FIG. 2.
  • the bearings 10, 40 are designed such that they allow the handlebar to slide in the axial direction as well as to pivot. By installing the bearings 10, 40 in the crossmember, the best possible power transmission between the handlebar and the crossmembers is achieved.
  • Figures 2 and 3 show a crossbar 1 in the form of a double T-beam, in the web of which a bearing housing 10 is installed at about half the height, which is machined internally cylindrical concave.
  • the actual bearing 40 is used in this housing, which is provided with a cylindrical outer shape with a through opening which is arranged perpendicular to the cylinder axis and corresponds to the handlebar cross section.
  • the bearing is preferably made of a plastic with good sliding properties, e.g. made of tetrafluoroethylene. It can be in one piece or composed of parts.
  • the bearing housing 10 can also be lined with plastic parts on the inside.
  • the essentially rectangular bearing housing 10 is welded into the crosspiece web.
  • FIG. 4 shows the strut 3 on a larger scale.
  • the middle part 32 consists of a solid rod, a hollow profile or profile strips, at the end of which a U-shaped bearing eyelet 33 is welded, which creates the connection to one end of the link 4 by means of the hinge pin 31.
  • the longitudinal axis of the handlebar runs obliquely to the longitudinal axis of the joint. So that this is possible, the strut is pivotally held on a tab 34 which is attached to the niche box N.
  • Two rubber-elastic disks 35 are provided which allow the strut to pivot by a few degrees.
  • one strut could also be arranged rigidly.
  • the other strut can then be held elastically, or can also be rigid and provided with a bearing similar to that of the crossbeams, in that the handlebar is pivotably and longitudinally displaceable.
  • FIGS. 12-15 Figure 12 shows two pivotably arranged struts 3, at the ends of the handlebar 4 is articulated.
  • Figure 13 shows an articulated and a rigidly attached to the joint edge strut 3 '. In this case, the deflection of the strut 3 is correspondingly greater.
  • FIG. 14 shows a further variant with two struts 3 'and 3 "rigidly attached to the joint edges.
  • the link 4 is pivotable on the strut 3' and pivotable and axially displaceable on the strut 3".
  • FIG. 15 shows two rigid struts 3 ′′ in which the link 4 is articulated and axially displaceable at both ends.
  • FIGS. 5-8 show variants of a crossbar bearing If the crossbeams are higher, the bearing does not have to be welded in for the handlebars, but can be screwed onto the web.
  • FIG. 5 shows such a bearing 50 from the front, FIG. 6 from the side and in FIG. VII in Figure 5, with the crossbeam 1 appearing in section 1.
  • the plastic bearing 51 is configured similarly to the bearing 40 in Figure 3.
  • This form of plastic bearing is easy to assemble or replace if wear and tear occurs.
  • the procedure is to first pull the handlebar 4 out of the bearing.
  • the bearing shell 40 or 51 can be rotated by 90 ° and removed from the bearing housing 10 or 50, as shown in FIG. 8.
  • the cross-sectional profile of the bearing shell is preferably U-shaped, so that it can accommodate both the lateral guidance and the contact pressure of the handlebar 4.
  • Figures 9-11 show a traverse 1 in more detail. It comprises a U-shaped bearing shell 10 made of forgeable cast iron, which is turned out cylindrically, welded between two sections 11 of an I-profile and is covered at the top by a welded flat iron 12.
  • a polished sheet of stainless steel 13 is attached to the bottom of the crossbar. For this purpose, it is bent in a U-shape and fastened to the sides of the flange by means of welding points 14.
  • the plastic bearing 51 could be spherical instead of cylindrical and the housing 50 could have a corresponding hollow spherical shape.
  • the slide bearings in the niches and the struts would then also have to be designed so that they can follow the movements of the trusses.
  • Figures 16 and 17 show a truss bearing, which is constructed similarly to the bearing of Figure 3.
  • the bearing housing here consists of a rectangular frame 15 welded into the cross member 1, which is precisely machined after welding. First, a base 53 (FIG. 17) is inserted into the frame 15 and then the hollow-cylindrical bearing pieces 54 are inserted into the frame.
