Definitions

  • the invention relates to a joint cover adjacent to the surface of the ferry track for expansion joints in traffic routes, in particular bridges, with an elastomeric mat which, with a central strip, loosely bridges the joint, is placed next to one another on the joint edges and is made of rigid material and with both edge strips is connected to the joint edges, the plates being fastened at least at one point to the underside of the mat.
  • a likewise prefabricated joint is described in Belgian patent specification 695 015.
  • an elastomeric mat is anchored in the region of the joint edges and is only connected in the middle on its underside to metal plates bridging the joint.
  • the disadvantage here is the disruption of the elasticity of the mat by this connection, in which the anchoring means engage in the mat.
  • the mat is only supported at a few points on its cross-section, which means that considerable wear can be expected.
  • the present invention has for its object to provide a locally cast joint cover, in which the joint bridging plates are held down by the mat itself and are controlled centrally with respect to the joint gap, without thereby affecting the elastic behavior of the mat.
  • this object is achieved in a construction of the type mentioned at the outset in that the elastomeric mat is cast in situ and in that an elastomeric projection is provided on the underside of the mat as fastening means, which is directly or indirectly engages in the plate or adheres to its surface.
  • the projection can engage in a cutout, an opening or a recess in the plate, or can be formed by a web between two adjacent plates, which engages in lateral recesses in these plates.
  • Such a web can also engage indirectly, namely with glow bolts anchored therein and projecting on both sides over the web surface, in lateral grooves of adjacent plates.
  • the projection is preferably produced together with the casting of the mat, that is to say as part thereof; It is also conceivable to prefabricate a dowel made of elastomeric material, which connects to the mat when it is cast to form an integral component.
  • the proposal of the invention ensures a mat without interfering engagement of fasteners, ie a mat is cast that has a uniform elastic behavior in its entire thickness and over the entire width.
  • the fastening means lie outside the mat body responsible for the mat elasticity and, moreover, have the same elastomeric properties as the mat itself.
  • the mat Since the mat is also manufactured stress-free on site, the risk of ⁇ bulging of the mat in the event of joint narrowing is largely eliminated.
  • the joint edges 1 are represented by cutouts in a concrete carriageway, the horizontal surfaces of the cutouts on both sides being provided with a layer 2 of elastomer concrete.
  • the two-sided layers 2 made of elastomer concrete form the base for the gap 3 bridging, in the longitudinal direction of the gap spaced plates 4 made of rigid material, preferably made of metal or a rigid plastic, such as. GFK (glass fiber reinforced plastic).
  • the plates 4 are laid in recesses of an insert 5 made of foamed plastic.
  • the insert 5 has openings in which the plates 4 are inserted before the whole is cast with an elastomer, such as polyurethane, so that an elastomeric mate 6 is formed which is flush with the top of the road 7. So that the plates 4 are always held in the center with respect to the joint gap 3, a connection between the mat 6 and the plates 4 is provided. This is created by filling two recesses 8 of each plate 4 with mat material.
  • the projections thus formed on the underside of the mat form elastomeric carriers 24 for the plates 4.
  • FIGS. 3 to 5 are the opening cylindrical, according to FIG. 4 conical with a smaller upper opening.
  • an elastomer bolt 10 preferably made of the mat material, is inserted into a cylindrical opening, which then connects to the mat 6 when it is cast. So that the mat material does not get into the joint gap 3 during casting, it is expedient to seal the openings in the plates 4 according to FIGS. 3 and 4 on the underside of the mat by means of adhesive strips II.
  • the mat material forms a firm, insoluble connection on the one hand with the vertical edges 12 of the roadway concrete, and on the other hand with the adjacent surface of the layer 2 made of elastomer concrete.
  • a central strip 14 of the mat 6 lies essentially on the plates 4, the upper side of which is provided with a (not marked separating layer, which precludes any connection between the mat 6 and the plates 4, and accordingly permits relative movements between the two components such a separating layer is of course not present in the area of the recesses 8 or perforations in the plates 4.
  • the plates 4 are in turn laid on the smooth surface of the layers 2 made of elastomer concrete and also provided with a separating layer on their underside.
  • the insert 5 made of foamed plastic has a greater thickness than the plates 4. This ensures that, starting from the edge strips 13 of the mat 6, a hold-down effect is exerted on the middle strip 14 when the mat 6 is compressed.
  • a vertical securing of the mat 6 is achieved by depressions 17 in the side flanks of the plates 4, without the longitudinal displacement of the plates 4 being prevented. It is also a prerequisite here that the plate surface is provided with a separating layer, for example wax, which makes an adhesive connection with the plates 4 impossible when the mat 6 is poured.
  • a separating layer for example wax
  • cams 18 are provided for delimiting the depressions 17 in the side flanks of the plates 4, which enable the horizontal movement of the plates 4 to be displaced.
  • a plastic film 23 running through in the longitudinal direction of the joint, which closes the joint cover downwards during the pouring of the mat, so that the mat material does not escape into the joint gap and which at the same time provides a separating layer opposite the layer 2 made of elastomer concrete in the area of the middle strip 14 of the mat 6 forms.
  • the embodiment according to FIGS. 9 and 10 has a particularly effective anti-lift device which prevents the composite of panels 4 and mat 6 from lifting upward when the joints are severely narrowed.
  • the mat 6 as already described for FIGS. 7 and 8, is guided through webs 19 in the spaces between the plates 4.
  • sliding bolts 20 are preferably made of a stiff, well-slidable material, e.g., like the plates 4 made of polyamide.
  • the grooves 21 are filled with foam, so that the webs 19 can deform into the grooves 21 under pressure, thus preventing jamming.
  • FIG. 10 shows a rod 22 made of a harder elastomer or of a tough platomer, which is provided in the middle of the mat and is provided in addition to the sliding bolts 20.
  • the rod 22 runs parallel to the longitudinal direction of the joint.
  • adhesive strips 11 running in the longitudinal direction of the joint can be provided to close the interstices between the plates before the mat is poured.
