Definitions

  • the invention relates to a device for bridging an expansion joint in a carriageway, in particular in the transition region to bridges, comprising a mat-shaped intermediate profile with a length 1, and an expansion joint in a roadway in the transition region to a bridge.
  • an expansion joint must be provided in the transitional area of the road to a bridge in order to bridge the changes in length of the bridge resulting from dynamic traffic loads, temperature fluctuations, shrinkage and creep.
  • the fingers are arranged interlocking.
  • the finger elements are bolted to a cast-in steel substructure.
  • changes in length are made possible by an elastomer profile mounted between two steel profiles. The profile is fastened by means of clamping flanges in the steel edge girders, whereby these transitions are watertight.
  • the total joint gap is divided into several single joint gaps by (steel) profiles (lamellae) running transversely to the carriageway. These single joint gaps are sealed against water and dirt by sealing profiles made of elastomer, which are knotted into the lamellae.
  • the slats are slidably mounted on trusses.
  • roller closure expansion joints are plates that slide on a gantry.
  • the mats can be offset with composite anchors directly to a concrete bed, the mats are attached to the composite anchors.
  • mats designs that have hollow channels and optionally a surface profiling, whereby the mat can absorb strains and compressions better.
  • the watertight connection is formed in the abutting region of two adjoining profile pieces by a shock lock.
  • a clip element has a first profile element (a so-called female profile) and a second profile element (a so-called male profile), wherein the first profile element has a recess and the second profile element has a profile section with a section corresponding to the cross-section of the recess Cross section has.
  • the first profile element is arranged on one of two adjoining profile pieces and the second profile element is arranged on the other of the two adjoining profile pieces. It is thus possible that the clamping of the profile pieces can be formed by simply pressing the male profile into the female profile, so that the individual profile pieces can already be placed correctly oriented to each other, without these for the preparation of the compound further manipulation with respect to their relative position to each other require.
  • an adhesive element is arranged in the joint areas between two adjoining profile pieces, via which in each case two adjoining profile pieces are glued together. Due to the additional arrangement of this adhesive element, the clamping element can be relieved or the strength of the connection can be increased. In addition, thus the water resistance of the joint area can be further improved. But it is also possible that this type of training the shock lock is provided alone, especially if the impact area is subject to a lower load, for example, at walking distance. or cycle lanes where the proportion of dynamic load caused by traffic is reduced compared to lanes with motor traffic. It should be noted, however, that the exclusive adhesive bond may be sufficient even in areas with motor vehicle traffic with appropriate choice of the adhesive or the geometry of the adhesive bond.
  • the adhesive element consists of two profile elements, wherein in each case one profile element is arranged on each one of two adjacent profile pieces, and the two profile elements are arranged one above the other, whereby the formation of the adhesive connection can be simplified.
  • the clamping elements and / or the adhesive elements are each formed integrally with the profile pieces, which on the one hand the manipulation effort can be reduced on the site, and on the other hand, no additional connection areas for connecting the clip elements and / or the 'adhesive elements with the respective Profile pieces are required.
  • the impact lock viewed in front view of the intermediate profile has at least one rising and at least one sloping area up. Through this "wave-shaped" course over the width of the intermediate profile, ie in the direction of the joint between two profile pieces, a better distribution of the forces acting on the intermediate profile forces can be achieved.
  • the intermediate profile has at least one expansion element, so that the intermediate profile can absorb higher expansion and compression forces.
  • the expansion element viewed in an end view of the intermediate profile particularly preferably has a W-shaped profile.
  • this allows a reduction in the overall height of the device, which makes it suitable, inter alia, for refurbishment purposes, Moreover, it has been observed that this profiling of the expansion element has advantages with regard to the noise development during crossings.
  • the lower overall height also makes it possible to achieve greater reliability in the case of conventional V-shaped expansion elements. elongation so great that the expansion element partially protrudes into the underlying open expansion joint. Excessive loads caused by the bridge pose the danger that the gap, ie the expansion joint, almost completely closes or narrows.
  • this gap narrows in the direction of the roadway in order to avoid “overpressing” of the expansion joint through the bridge, nevertheless, in the case of a V-shaped expansion element In the case of the larger vertical dimension, this expansion element can be pinched at the high pressure exerted by the bridge and ultimately sheared off.
  • the profile sections have a maximum length of 1.5 m. It is thus possible that these profile sections are manipulated manually, whereby their installation on the construction site can be performed easily without a crane. In conjunction with the above-described possibilities for forming the butt lock, a high fatigue strength and a high watertightness of the device is achieved despite the higher number of connection regions connected thereto over the length of the intermediate profile.
  • the mat-shaped intermediate profile is adhesively bonded at least approximately to the entire surface of the support surface, whereby the structural strength of the expansion joint can be improved.
  • the expansion joint is wave-shaped, whereby the ride comfort during the crossing can be improved. In addition, the noise development during the crossing can be reduced.
