Definitions

  • the invention relates to a roller shutter for expansion joints of bridge structures and. Like., Which consists of pendulum plates anchored on one side of the joint with articulated sliding plates and of tongue plates anchored on the opposite side of the joint and resting on the sliding plates, the sliding plates resting with sliding elements arranged on their lateral edges on the approximately circular sliding track of sliding blocks.
  • Bridge structures provided with a carriageway or a walkway require additional bridging of the expansion joints between the structural parts, which can be up to 150 cm wide for long bridge lengths.
  • So-called roller shutters which are installed as a special component in the area of the expansion joints, serve this purpose in a known manner (cf.Köster, W., carriageway crossings in bridges and concrete tracks, 1st edition 1965, pages 148-155; Bauverlag GmbH, Wies to bathe).
  • sliding plates are articulated to the pendulum plates bridging the expansion joint, which can slide on the sliding track of sliding blocks in the event of thermal expansion under the overlying tongue plates.
  • sliding cams which at the same time also represent the articulated connection between the pendulum plate and the sliding plate or between the sliding plates, in that they are designed in the form of a tab, are provided with an articulated bore and an articulated pin.
  • sliding cams which at the same time also represent the articulated connection between the pendulum plate and the sliding plate or between the sliding plates, in that they are designed in the form of a tab, are provided with an articulated bore and an articulated pin.
  • the invention has for its object to form a roller shutter of the generic type in such a way that the wear is considerably reduced, the remaining wearing parts can be replaced easily and quickly and no rattling noises arise when driving over.
  • the sliding elements consist of a sliding piece vertically guided in a bearing pot and the spherical bearings of the sliding plates are arranged offset inwards.
  • the sliding elements and the spherical plain bearings are arranged separately from one another.
  • the spherical plain bearings therefore essentially only absorb the horizontal forces and are hardly exposed to wear.
  • Wear parts are practically only the sliders, which are not only easy to replace due to the arrangement in a bearing pot, but can also be selected as a single component for the best possible slidability.
  • it is only necessary to remove the worn sliding pieces from the bearing pots and to replace them with new sliding pieces. This replacement requires neither welding work nor the application of sliding layers and can be carried out per lane in a few hours.
  • Existing systems can advantageously be converted according to the invention.
  • a spring element which pushes the slider down is arranged in the bearing cup.
  • the resilient mounting of the sliders on the slideways leads to a full and therefore noiseless system in all areas. Two of the four support points always adapt to the slideway, so that the effect of a self-adjusting four-point support is created.
  • the spring element can consist of a steel spring. However, it is preferably formed from an elastic plastic body, which is fastened by means of an integrally formed pin in a guide bush guided in the piston in the bearing pot. Such an elastomer spring ensures a uniform distribution of the bearing forces on the associated slider.
  • the sliders are only inserted into the bearing pots, i.e. are not welded, screwed or similarly firmly attached to the sliding plates, they can be made in a particularly simple manner from a sliding material, for example from a metallic sliding material or a sliding bearing plastic. If, according to a further feature of the invention, the sliding path of the sliding blocks is provided with a sliding plate made of a hard, non-corrosive counter-rotating material, the frictional wear is considerably reduced and the operating time until a necessary maintenance or repair is greatly increased.
  • a roll closure which essentially consists of pendulum plates 4, articulated sliding plates 5, tongue plates 6 and sliding blocks 7, which have approximately circular arcuate trajectories 8.
  • Each unit consists of a pendulum plate 4, articulated sliding plates 5 and a tongue plate. 6 has a width "a" of about 100 to 120 cm, and depending on the roadway width of the bridge structure, a large number of such units lie side by side.
  • the pendulum plates 4 are each in a pendulum-like manner in two self-aligning bearings 9 on the bridge component 1 which is displaced by thermal expansion and are provided with spring-loaded anchors 11.
  • a corresponding storage and anchoring can be found on the connecting structure 2 for the tongue plates 6, the self-aligning bearings being designated 10 and the spring-loaded anchors 12.
  • the self-aligning bearings being designated 10 and the spring-loaded anchors 12.
  • the sliding blocks 7 are arranged next to one another such that a sliding track 8 is located below the longitudinal joints 13 present between two adjacent units (cf. FIG. 1).
  • Each self-aligning plate 4 has a four-point bearing, which consists of the two self-aligning bearings 9 and two sliding elements 14, which are attached to the end opposite the self-aligning bearings 9 at the side edge, ie at the corners.
  • the glide hinged to it plates 5 each have a sliding element 14 at their corners facing the connecting structure 2.
  • the articulated bearings 15 intended for the articulation of the sliding plates 5 are, as shown in FIGS. 1 and 3, offset inward next to the sliding elements 14.
  • Each slide plate 5 is connected by two such spherical bearings 15 to the component in front, the pendulum plate 4 or a slide plate 5.
  • each slide plate 5 also has a four-point bearing, formed by two slide elements 14 and two spherical bearings 15.
  • Each unit consisting of a pendulum plate 4 and three slide plates 5 is therefore based on two slide blocks? from, however, each slide block 7 also supports the next unit.
  • the sliding elements 14, as shown in particular in FIG. 4, consist of a sliding piece 16 which is vertically displaceable in a bearing pot 17. They consist of a suitable sliding material, e.g. B. a bearing metal alloy or a plain bearing plastic (polyamide, polytetrafluoroethylene or the like.).
  • a spring element 18 is provided in the bearing cup 17, which lies in a piston-like guide bushing 20.
  • This spring element 18 consists of an elastic plastic body (elastomer) and is held centrally by means of a molded pin 19.
  • sliding plates 21 made of a hard non-corrosive counter-rotating material, e.g. B. stainless steel attached.
  • each bearing consists of two bearing brackets 22 attached to one component and an intermediate bearing bracket 23 attached to the other component, which are connected by a hinge pin 24.
  • both the spherical plain bearings 15 and the sliding elements 14 located next to them lie in a transverse alignment line.
  • the sliding elements protrude somewhat beyond the transverse joint 25 to the articulated sliding plate 5, which is provided with a corresponding corner cutout in this area.
  • the sliding plates 5 and the pendulum plates 4 move on the sliding tracks 8 or sliding plates 21 and under the tongue plates 6.
  • the pendulum plates 4 and the tongue plates 6 together with the intermediate part of the sliding plates 5 form one almost flat surface.
  • more or fewer sliding plates 5 can also be provided for each unit.
  • the design of the spherical bearings 15 and the sliding elements 14 can be different.
  • a plate spring or another steel spring can be used instead of the spring element 18 made of an elastic plastic body.
  • an elastic plastic body 18 directly to the slider 16, or of connecting both parts in the manner of a composite material.
  • a coating made of a suitable counter-rotating material e.g. high-strength chrome steels
  • a spring-loaded lever arm or the like B. in the manner of a pendulum axis or torsion spring.
