Definitions

  • the invention relates to a device for bridging expansion joints, in particular in carriageways, as a waterproof joint cover that runs lengthways along the joint, with individual support plates that are spaced apart in the longitudinal direction of the joint and that bridge the joint and that have elastomeric intermediate layers that are continuous in the longitudinal direction of the joint are connected in a shear-resistant manner to edge profiles anchored in the joint edges, movement joints open at the top 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 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.
  • the elastomeric butt joint between the elements largely avoids force bridges which have a mutual influence on the armature loads.
  • 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 embodiment which is advantageous for the dissolution into individual elements consists in that troughs and crests of the corrugated 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 center 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 thrust bearing embodied by the wave crests of the elastic webs.
  • 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 with elastomer on their top. Material be coated.
  • Figure 1 is a schematic plan view of the joint cover with two elements, with the lower half of the drawing shows a lower horizontal section according to II of FIG. 4,
  • FIG. 2 shows the two edge profiles of an element of the joint cover, in a top view
  • FIG. 3 shows the top view of a support plate
  • FIG. 4 shows a vertical joint cross section according to IV-IV of FIG. 1,
  • FIG. 5 shows a cross section through the connection profile of two support plates according to V-V in FIG. 1,
  • Figures 6 and 7 each have a cross section through the
  • Figure 8 shows a vulcanization connection using the example of the connection profile shown in Figure 5 and 9 shows an adhesive connection using the example of a connection profile shown in FIG. 5.
  • FIGS. 1 to 3 of the drawing show different components of a preferred embodiment, each in a top view, while FIG. 4 shows a vertical cross section according to IV-IV of FIG. 1 for this embodiment.
  • 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 to the web connection part 10 of a shear-resistant part on the one hand with the underside of the support plates 1 and on the other hand with the elastic web 11 connected to the top of the base plates 5 Elaststeg 11 formed thinner than in its other 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 in order to ensure a perfect folding 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.l. 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.

Abstract

Un recouvrement pour joints de dilatation dans les chaussées est composé de différents éléments préfabriqués contenant chacun une plaque de base (1), lesquels sont reliés entre eux de manière étanche au moyen de profilés de raccordement élastomères dans des plans de joint perpendiculaires au joint. Chaque élément comporte en plus de la plaque de base (1) deux profilés de bordure ancrés des deux côtés du joint (14) dans le sol de fondation du joint (7), ainsi qu'un joint de cisaillement élastomère entre lesdits profilés de bordure et la plaque de base. A cet effet on utilise une âme élastique (11) ondulée en vue de dessus, dont la forme ondulatoire est adaptée à celle des tôles de bordure (2) des profilés de bordure (3).
