Definitions

  • the invention relates to a device for bridging expansion joints, in particular in roadways, as a waterproof joint cover running lengthways along the joint, with individual support plates which are spaced apart in the longitudinal direction of the joint and which bridge the joint and which are resistant to shear via elastomeric intermediate layers which are continuous in the longitudinal direction of the joint edge profiles anchored in the joint edges, with upwardly open expansion joints running on both sides of the joint between the intermediate layers and the edge profiles, the edge profiles each consisting of an edge plate and a floor plate adjoining it on the joint, resting on the substructure of the joint edge.
  • the present invention has for its object to provide a particularly durable joint cover of the generic type, which also allows a largely shock and noise-free driving over.
  • the joint cover is composed of individual elements, each of which contains a support plate, the life of the screw anchors is significantly extended. Due to the elastomeric butt joint between the elements, force bridges, which lead to mutual influence of the anchor loads, are largely avoided.
  • joint cover By dissolving the joint cover into individual elements, these can be produced in stock in order to be connected to one another in a corresponding number for a specific application by means of the elastomeric connection profiles by vulcanizing or gluing.
  • the elastomeric connection profiles enable the joint cover to be rolled up, which is advantageous for transport. This can also easily adapt to a curved road surface, similar to an articulated chain.
  • An advantageous embodiment for the dissolution into individual elements consists in that troughs and crests of the undulating components of the joint cover lie on both sides of the joint in the same vertical plane running transversely to the joint. In other words, measured from the middle of the joint, there are always two wave crests or two wave troughs opposite each other, the wave troughs corresponding to constriction areas. It is particularly expedient that the vertical planes through the troughs are the parting planes. This has the advantage that the connection profiles are located in the constriction areas, where they are only slightly stressed in the case of joint expansion by folding in more or less. The elastomeric connection profiles lie outside the area of the actual drawer bearings embodied by the wave crests of the elastic webs.
  • Butt joints that are easy to implement are vulcanization joints or adhesive joints.
  • TPE thermoplastic elastomers
  • Both the edge profiles and the support plates are made of steel or sheet steel, so that they can withstand the high wheel loads. All metal components of the joint cover can be coated on their top with elastomeric material.
  • FIGS. 1 to 3 of the drawing show various components of a preferred embodiment, each in a top view, while FIG. 4 shows a vertical cross section according to IV-IV of FIG.
  • the edge profile 3 usually consists of a shell-like molded part made of sheet steel. As indicated in FIG. 6, it can be covered with an elastomer layer 8 on the upper side.
  • the vertical parting planes T are located in the narrow points of the joint cover. There, the individual elements of the joint cover are connected to one another by means of elastomeric connecting profiles.
  • the elastomeric connection profiles of the vertical components are arched toward the joint. This applies both to the edge connection part 9 of the edge plate 2 and for the web connection part 10 of a shear-resistant elastic web 11 connected on the one hand to the underside of the support plates 1 and on the other hand to the top of the floor panels 5.
  • the elastic web 11 is thinner than in FIG its remaining sections, where it has to absorb thrust and traffic loads.
  • the thinner wall thickness of the web connecting part 10 reduces the stresses on the elastic web due to the deformations occurring in the division plane T.
  • connection part 12 is in FIG. 5 in cross section according to VV of FIG. 1st shown. It is arched downwards to ensure that it folds in properly when the support plates 1 approach.
  • the base plates 5 of the edge profiles 3 are each sealed together in the region of the division plane T by means of an elastomeric base connection part 13.
  • a bottom connection part 13 is shown in Fig. 6 in cross section according to VI-VI of Fig.1. It is arched downwards so that it lies smoothly and sealingly on the substructure 7 in the region of the joint edge after the assembly of the floor plates 5, as shown in FIG. 7. 6 and 7, the base plates 5 are coated with an elastomeric layer 8, which is molded onto the base connection parts 13.
