Definitions

  • the invention relates to an element for noise barriers with the features of the introductory part of claim 1.
  • Known elements for noise barriers have between one, in particular perforated, front wall (“front panel”) and one, in particular not perforated, rear wall (“front panel”) arranged at least one insulation board. At the upper edge of the element is a top flange and at the bottom of a lower flange provided.
  • noise protection panels which are composed of noise protection elements
  • noise protection panels are subject to the resulting stresses by pressure and suction while driving past a train not adequately withstand.
  • noise protection elements which are known in the prior art are dimensioned on the basis of static experimental setups. This means that dynamic effects must be covered by static reserves. In the known elements for noise barriers neither dynamic loads, fatigue calculations nor combination models for dimensioning of noise protection elements are required. All of these effects and requirements are covered by static replacements.
  • the invention is based on the object to present an element for noise barriers, which meets the requirements, in particular the requirements of their use on high-speed rail lines.
  • the inventive design of the element for noise protection walls allows the sizing by computer models in combination with experiments optimally set and also the location of joints (eg rivets) to be selected so that all joints are evenly loaded and so the strength of the element according to the invention in such a way that it complies with continuous load, namely withstands.
  • joints eg rivets
  • the side cover of the element according to the invention for noise barriers as deep-drawn sheet metal parts with, z. B. by embossed stiffening knobs in the angular range of the flanges good static or dynamic properties are formed.
  • the deep-drawn sheet metal parts which serves as a lateral cover on both sides of the element, connected to the upper flange and lower flange. So will a given static and obtained dynamic system.
  • stiffening elements which extends transversely to the front wall and the Rear wall, so the front panels, extends and connected to these walls, for example by riveting.
  • stiffening elements which may be formed as the side covers, result in an improvement of the damping effect.
  • load-bearing elements in particular upper flange and lower flange, are dimensioned so that they meet the static and dynamic requirements.
  • rivets are preferably used for the connection of upper flange, lower flange and the lateral lids and, if appropriate, also the at least one stiffening element which is present between the lateral lids and which is preferably oriented parallel thereto. This allows the rivets to be arranged so that the element then obtained for noise barriers meets the static and dynamic requirements even when used in noise barriers on high-speed lines.
  • Upper chord and lower chord may be formed as profiles with, preferably two longitudinal, cavities, which improves their torsional rigidity.
  • the front panels can be designed according to the invention with (two) beads, which increases the Beulfestmaschine serving as the front wall and rear wall of the elements according to the invention front panels.
  • the elements according to the invention for noise barriers can be flat or curved.
  • Curved elements use curved side lids and, if provided, curved stiffeners disposed between the side lids.
  • the elements are curved about a horizontal axis in the position of use, such that the concave side of the noise source is facing.
  • An inventive element for noise barriers consists in the embodiment shown in the drawings of a profiled upper flange 1 and a profiled lower flange 2, which are formed so that the - upwardly facing - outside of the upper flange 1 in the - downwardly facing - outside of a lower flange 2 (positive fit) fits so that noise barriers of noise protection elements according to the invention can be formed by stacking such noise protection elements in any amount.
  • Both the upper belt 1 and the lower belt 2 have longitudinal hollow chambers 30, 31. From top chord 1 and bottom chord 2, slats 32 protrude into the interior of the element. Between these strips 32 cement fiber boards can be used.
  • a noise protection element according to the invention has lateral covers 3, which are aligned perpendicular to the lateral edges, are arranged.
  • an element according to the invention for noise protection walls has an optionally profiled front plate 5 which is arranged as a front wall on the side of the element facing the noise source and a front plate 5 arranged on the side of the element remote from the noise source and serving as a rear wall
  • the front panels 5 each have two mutually parallel beads 33 which extend horizontally in the position of use.
  • Both the side cover 3 and the front panels 5 have at their edges bends 11, 13, wherein the side cover 3 are arranged so that the folds 11 face outward, whereas the folds 13 of the front panels 5 point inward.
  • the said components of the element according to the invention for noise barriers namely upper flange 1, lower flange 2, side cover 3 and front panels 5 are connected to each other by means of rivets 15, wherein the arrangement of the rivets 15 according to the static requirements, for example on the basis of calculations and experiments Determining the fatigue strength of the rivets 15 and the fatigue strength of the aluminum alloy, from which the parts of the noise protection element consist, is selected.
  • the arrangement of the rivets 15 in the embodiment shown in Fig. 1 is merely exemplary.
  • a possibly multi-layered, sound-insulating insert is arranged, which is not shown in the drawings. It is also considered an embodiment in which are arranged in the element for noise protection walls on both sides of a fiber cement board layers of sound-absorbing material.
  • At least one stiffening plate 4 can be arranged in the element according to the invention for noise protection walls, which is designed as the lateral cover 3 and is connected by rivets 15 at least to the top flange 1 and the bottom flange 2.
  • profiles 6 are attached as holders for tubular sealing strips 7, which are also fastened by means of rivets 15.
  • the rivets serve 15 for attaching the profiles 6 at the same time also to connect the side cover 3 with the respective associated front panel 5.
  • the sealing strips 7 have a keder shame Anformung 20 and a substantially tubular profile strip 21 which protrudes from the element to the outside.
  • the kederförmige Anformung 20 is positively inserted into an undercut groove in the holder 6 for the sealing strip 7 and can be clamped there.
  • the profiles 6, which serve as a holder for the sealing strips 7, can be available in various sizes. Thus, the distance of sealing strips 7 can be selected adapted to the free space at Stehern the noise barriers by the appropriately sized profiles 6 are used.
  • the tubular part 21 of the damping elements 7 is under elastic deformation of the associated surfaces of uprights 22, between which the elements according to the invention are used in the construction of noise barriers to. This is schematically indicated in Fig. 2, but the tubular strip 21 of the damping sealing strip 7 is shown without deformation.
  • One end of the sealing strips 7, in particular the lower end of the tubular part 21 thereof in the position of use, may be chamfered or rounded in order to simplify the insertion of panels according to the invention between the uprights 22 (I-beam).
  • Fig. 3 is still shown as the rivets 15 are set in the region of an upper corner of an element for noise barriers.
  • noise protection elements allows a multi-stage calculation, design and optimization of the elements for noise barriers in terms of durability.
  • An element for noise barriers consists of upper flange 1, lower flange 2, arranged between these front plates 5 and side covers 3, which are connected to each other by rivets 15. Between the front panels 5, which can be executed perforated on one side or both sides, sound-absorbing, insulating inserts are arranged. In order to increase the stability, at least one further stiffening element 4 can be provided between the side covers 3 in addition to the rivet connections, which result in a stable frame of top flange 1, bottom flange 2 and side covers 3. These stiffening elements 4 are connected to the front panels 5 and / or the upper and lower chords 1.2 by riveting.
