Definitions

  • the object of the invention is to provide a simple, lightweight noise protection element Specify concrete with sound-absorbing filling, which has a high Dimensional stability, uniformity of quality and durability.
  • the invention provides in a preferred embodiment, that the sound side facing away from (2) has a textured surface.
  • the textile reinforcement consists of alkali-resistant fibers, preferably alkali-resistant glass fibers.
  • fibers which are not alkali-resistant but in this case a binder which is not or only slightly alkaline must be used as matrix for embedding.
  • the fibers are preferably not biased. A bias is possible in principle.
  • the transverse reinforcement preferably runs circumferentially in the matrix.
  • Fig. 1 shows in cross section the rough structure of an inventive Element, for the sake of clarity without representation of the invention essential reinforcement therein, but their location in the following is described.
  • a baffle with nubbed die is used to produce the perforated, sound-facing side (1). It demountable side molds are used, the via a profile for tongue and groove (4) from the top and bottom of the Noise protection element have.
  • the edge / end formwork are with a Provided device for biasing the longitudinal reinforcement.
  • Noise protection element which has a length of five meters, a Height of 66 centimeters and a thickness of 12 centimeters.
  • a Noise barrier is made by stacking several such elements built up.
  • the formwork must be cleaned in advance and sprayed with formwork oil.
  • the longitudinal and transverse reinforcement is to be prepared in advance for an element.
  • the Transverse reinforcement is mounted on longitudinal strips and wound up.
  • the longitudinal threads are preloaded on the clamping frame and fixed on cross bars. It is important to ensure a uniform tension of the threads.
  • the first concrete layer of the front (1) with a height of approx. 3 mm is installed in the prepared formwork.
  • the installation takes place with the metering funnel, so that contamination of the formwork knobs can be largely avoided.
  • the transverse reinforcement is first applied on the first layer concrete of the front side.
  • the longitudinal strips are positioned centrally above the element and the transverse reinforcement unwound on both sides evenly and with slight tension over the element.
  • the transverse reinforcement required for the webs and rear remains on the longitudinal ledges until further notice and is deposited next to the formwork.
  • the longitudinal reinforcement is clamped. About the two transverse strips, the longitudinal threads are fixed under slight bias in the formwork.
  • the Endabschaletti be mounted.
  • the second concrete layer of the front (1) is installed with the hopper. It should be noted that the concrete flows evenly into the formwork and protrudes after installation about one millimeter of the formwork knobs out of the concrete. As a result, a closure of the absorption holes (3) of the noise protection element is avoided.
  • the table vibrators can be switched on. Before laying the insulation boards (5) the formwork knobs are pulled off again with a board to remove any existing concrete residue. The insulation boards (5) are placed on the knobs of the formwork and laterally covered with a foam strip to absorb shrinkage deformation of the element when setting the concrete harmless. The insulation boards (5) are chamfered in the longitudinal direction on the top and bottom. In order to avoid floating of the insulation boards when filling the concrete of the side bars, the insulation boards are ballasted. To assemble the side moldings, the transverse reinforcement is folded over and then placed laterally next to the formwork.
  • the concrete for the side bars is filled up to the upper edge of the insulating board.
  • the adequate filling of the side bars must be checked and, if necessary, ensured by further addition of concrete.
  • the ballast on the insulation boards (5) is removed.
  • the first layer of concrete back (2) is applied to the insulation boards (5).
  • the longitudinal reinforcement of the back (2) is clamped in the formwork and fixed.
  • the transverse reinforcement is folded over and laid overlapping on the back (2).
  • Abziehelfn are attached to the Endabschalettin.
  • the installation of the last concrete layer of the back (2) is timely, so preferably fresh in fresh, carried out. Care must be taken to ensure that sufficient concrete is poured in to avoid reduced thickness of the concrete section.
  • the removal of the back (2) of the noise protection element and a desired structuring with brush stroke or Sandeinstreuung takes place.
