Definitions

  • the strip is mounted in recesses in the structure on retaining ribs form for example the web of a T-iron I whose flange is bolted firmly to a plate, web and flange being mounted on the floor of the carriageway recesses on both sides of the expansion joint.
  • the invention provides an expansion joint for adjacent roadway sections having a gap therebetween to allow expansion of said section, said sections being recessed along their adjacent edges to form a groove along both sides of said gap, said joint comprising a plate structure fixed to each section along the '-ter, dust, dirt or the like is' achieved ifthe vertical bottom of said groove, each of said plate structures having a support projection to and spaced from said gap, said recessed sections supporting an expansion member extending into said grooves, said expansion member consisting of a strip of. elastic material, both sides of said strip surrounding ribs, said ribs each comprising a series of individual sections running in the lonthe part of the joint insert lying between them can be provided with a certain pre-tension during installation.
  • This pre-tension ensures that the lateral edge of the joint strip does'not lift away from its abutment even under extreme expansion conditions.
  • the pre-tension can be set at different levels, since the retaining ribs consist of individual sections. A varying degree of pre-tension is advantageous, since experience shows that individual sections of the joint insert are continually subject to the strain of vehicle wheels, which is less often the case with the sections lying between them. The squeezing effect of the vehicle wheels also acts differently on the joint strip dependently on the direction of travel, and this can also be taken into account when setting the pre-tension.
  • a particularly simple construction of the cover can be achieved if the plate structures with the support pro- I jection in the structure recesses are angle-irons, having the horizontal flanges thereof mounted on the floorof the recess adjacent the expansion gap, and the vertical flanges having holes for the tensioning bolts to pass through.
  • flange extends up to the surface of the structure and forms a continuous bearing surface for the lateral edge of the joint strip.
  • the retaining ribs can be arranged to be divergent towards the floor of the carriageway recess in relation to the vertical flange of the angle-iron.
  • the underside of the strip can advantageously be provided with at least one arch-like recess running in the longitudinal direction of a the strip between the two retaining ribs.
  • FIG. I shows an example of embodiment of the joint I cover for largely non-moving structural parts
  • FIG. 2 shows the joint cover in accordance with FIG.
  • FIG. 3 shows a further embodiment of the joint cover
  • FIG. 4 shows a further embodiment of the tensioning members. 1 t
  • an expansion gap or joint 10 is provided between the two parts ll and 12 or a structure such as a bridge, a roadway, a carriageway or the like.
  • the foundation generally consists of concrete and has a covering 13 with an asphalt layer 14 which forms the road surface.
  • the covering 13 consists generally of bitumen and rests on the foundation with an insulating plastics layer 15 between them.
  • the layer 15 may be a gIass-fibre-reinforced mat.
  • Each structural part 11 and 12 has parallel to the expansion gap or joint 10 and angle-iron 16 which has a horizontal flange 17 and a vertical flange 18.
  • the horizontal flange 17 is fixed to the floor 19 of the carriageway recess by being welded to an anchoring member 20 provided in the foundation.
  • a free surface 21 of the flange 17 is formed flat as an application surface for the joint strip 22.
  • the vertical flange 18 of the angle-iron 16 extends up to the surface of the carriageway. Along its length it has several holes 23 through which the tensioning bolts 24 pass. A head 25 of the tensioning bolts 24 bears against the surface of the vertical flange 18 facing towards the bitumen layer 13.
  • retaining ribs 26 are inset into the joint strip 22.
  • Each section of the retaining ribs 26 advantageously has two threaded bushes 27 facing outwards and ending a short distance from the free side surfaces 28 of the joint strip 22.
  • the tensioning bolts 24 are in engagement with the threaded bushes 27 in such a way that during'installation of the joint strip 22 there can be exerted on its sections a pre-tensionv which lies between the retaining ribs 26 and the vertical flanges 18.
  • the surface 28 is pressed flat against the inward-facing surface of the vertical flange l8 and provides under all load conditions a tight seal against the entry of water, dampness, dust, dirt and the like.
  • the retaining ribs 26 consisting of individual sections enable the joint strip to be delivered in long lengths, which can then be cut to to correct length by the constructionworkers. Special tools are not necessaryfor this, since only the resilient strip 22 between the sections of the retaining ribs 26 has to be divided up. In this way the strip can also be cut to size by mitring and can be laid without interruption over ledges.
  • the bolt heads 25 lie open, for setting of the pretension. They can then in accordance with FIG. 1 be covered by the insulating layer 15. Then the bitumen covering 13 and the asphalt layer 14 are laid as far as the layer- 15 or the vertical flanges 18.
  • FIG. 2 shows the cross-section of a joint cover 22 for structural parts which move in relation to one another. Identical parts are provided with the same reference numerals.
  • the joint strip 22 has two arch-like recesses 29 on its underside between the retaining ribs 26. The two recesses 29 run in the direction of the expansion joint '10. Between the recesses 29 there is formed a support surface 30 on the joint strip 22. The support surface 30 rests on the floor 19 of the recess of the carriageway 11.
  • slot-like recesses 31 there are provided slot-like recesses 31. These slot-like recesses 31 likewise run in the direction of the expansion gap 10 and are aligned with one another. They may for example be of the same length as the sections of the retaining ribs 26.
  • the rigid plates 32 likewise consist of individual sections.
  • the recesses 29 merely ensure that the strip is pressed in the direction of the support surface 30 in accordance with the arrow P, and is pressed by this surface firmly against the surface 19.
  • the joint strip 22 therefore does not bulge evenly in the form of a dome, but merely forms a slightly undulating line during strong compression. lf the strip in this form is subjected to rolling loads, then the strip is not pushed along its whole length from one position to another, since part of the movement is already taken up in the region of the support surface 30. In this way it .is prevented that the side surfaces 28 are dragged too strongly away from the vertical flanges 18, so that even under extreme loads a proportion of the pre-tensioning is certain to remain, so that any entry of moisture ordirt is prevented.
  • the slot-like recesses 31 and/or the rigid plates32 favour the deformation of the strip 22 in the direction of the arrows P during the compression.
  • the slot-like recesses 31 on the top side of the strip also permit a compensation of forces in the surface region, especially lustrated for the structural part 11, so that recess means I 38 can be illustrated more clearly while for the structural part 12 a tensioning bolt 24 is shown. lt is to be understood, however, that ten'sioning bolts are provided for ,both parts 1 l and 12.
  • the retaining ribs 36 in this embodiment have an aperture in which the threaded bushes 27 are inserted.
  • a further angle-iron 33 whose vertical flange 34 abuts against the vertical flange 18 of the angle-iron 16.
  • a horizontal flange 35 of the angle iron 33 lies somewhat lower than the horizontal flange 17 of the angle-iron 16 and is likewise connected to the anchor 20.
  • the two vertical flanges l8 and 34 contain holes 23 for the penetration of the tensioning bolt 24. This arrangement is suitable for greater pre-tensionings and wider gaps.
  • the insulating plastic layer 15 can as in the preceding example of embodiment extend up between the wedgeshaped strip 37 and the angle-iron 33 to the surface of the carriageway.
  • the vertical flanges 18 and 34 of the angle-irons 16 and 33, ending below the surface of the carriageway in this embodiment, are protected to a perticularly high degree.
  • the bitumen layer 13 and the asphalt layer 14 are laid as far as the strip 37.
  • FlG. 4 shows a modified form of embodiment of the mounting device, in which retaining ribs 46 are divergent towards the floor 19 of the carriageway recess in relation to the vertical flange 18 of the angle-iron 16.
  • the inclined arrangement of the retaining ribs 46 ensures an even pre-tensioning. In the event of compression of the joint strip 22, however, the latter is pressed morestrongly against the substructure, i.e., the surfaces 19 and 21 of the horizontal flanges 17. This leads to a further mounting of the strip in relation to the foundation.
  • the slot-like recesses 31 on the surface of the carriageway and also the dome-like recesses 29 on the underside of the joint strip 22 ensure that during pretensioning and also during working as a result of weather and mechanical effects, the sealing in the region of the surfaces 21 and 28 is maintained for the protection of the metal parts.
  • An expansion joint for adjacent roadway sections having a gap therebetween to allow expansion of said sections, said sections being recessed along their adjacent edges to form a groove along both sides of said gap, said joint comprising in combination a plate structure fixed to each section along the bottom of said groove, each of said plate structures having a support projection parallel to and spaced from said gap, said recessed sections supporting an expansion member extending into said grooves, said expansion member consisting of a joint strip of elastic material having free side surfaces, retaining ribs inset in said strip, said ribs each comprising a series of individual sections running in the longitudinal direction of the strip and each of individual sections being provided with at least one threaded bush, said bush having an axis arranged transversely to the expansion gap, said bushes each engaging with a tensioning bolt which bears freely and rotatably against a corresponding support projection in said groove, said plate structures having a support projection being fixed in the recessed sections comprising inlaid angle-irons having the horizontal flanges thereof mounted on the floor of the recess, adjacent the
