Definitions

  • the present invention relates to noise-damping restraint systems and their use as a noise barrier.
  • Transparent soundproofing elements can consist of plastic glass panes, which can be connected to soundproof walls with suitable fastening devices. Transparent soundproofing elements are increasingly used in areas where it is necessary to perform the noise protection measures as inconspicuously. This is especially necessary on bridges and in urban areas. Such transparent noise barriers are made in particular of polymethyl methacrylate (PMMA) or based on PMMA molding compounds, as this material has excellent transparency and optical properties and good sound insulation with good physical and mechanical properties (stone dust resistance). From the DE-G 90 10 087.5 It is known that in plastic glass panes, which simultaneously represent a single soundproofing element, plastic threads can be pulled, which hold the individual fragments in the event of breakage of the plastic glass pane and prevent them from falling.
  • PMMA polymethyl methacrylate
  • EP-A-0 559 075 Acrylic noise protection elements containing embedded spirals to prevent splintering of the noise barrier in case of breakage.
  • the interiors of the coils, which contain steel springs, are hollow at least in part of their cross section or filled with a deformable medium, for example oil. These measures are intended to ensure that fragments formed during an impact are held together.
  • EP-A-0 559 075 is essential that the coil springs high mobility within the Have plastic matrix. This high mobility is ensured by the aforementioned cavities.
  • EP-A-0 559 075 to this end states that steel springs have a high modulus of elasticity. As a result, the tensile forces increase so quickly even at low elongation that the tensile strength at breakage of the plates can be exceeded.
  • cavities described can be created by displacement body, which are pulled out after production of the plates.
  • EP-A-0 559 075 There are no indications of a plastic layer, which is arranged between the steel springs and the plastic matrix.
  • a disadvantage of an article according to EP-A-0 559 075 is in particular the high production cost of acrylic sheets.
  • a first cast-in displacement body must be carefully removed from the plate before the thus resulting cavity can be filled, for example, with oil.
  • the oil generally degrades rapidly due to weathering. This can lead to visual impairments of the soundproofing wall. If no oil filled in the cavities, so there is a risk that water penetrates, which can lead to damage to the wall, especially in winter. Freezes into the cavities penetrated water, so the wall can be destroyed by this.
  • the aforementioned soundproof walls only prevent splintering of the noise barrier. If a vehicle encounters a known acrylic sheet at high speed, the car generally cuts through the noise barrier. It should be noted that the high mobility of the coil springs can lead to a detachment of the springs. Additional devices that could prevent leaching are in EP-A-0 559 075 not described. However, such devices would have an immediate Connection to the steel wires have, so that there is a risk that water enters the cavities. Furthermore, such devices should be made of high quality metal and constructed consuming. Accordingly, such a device would be expensive and very expensive.
  • Another object of the present invention was to provide a sound-absorbing, aesthetically pleasing restraint system that can be manufactured particularly cost-effectively. Furthermore, the invention was the object of providing a restraint system, the beautiful aesthetic impression of a noise barrier made of acrylic glass or only slightly affect.
  • Another object of the present invention was to provide sound-absorbing retention systems which have a particularly high weather resistance.
  • the noise barriers of the present invention can be produced in a particularly simple and cost-effective manner.
  • the retention system integrated in the acrylic glass panels is characterized by a particularly high weather resistance, since it is completely surrounded by plastic.
  • the term restraint system denotes a device which is suitable for preventing an impacting object, for example a vehicle, from breaking through the device.
  • a restraint system according to the invention can prevent one from being perpendicular to the system impacting article which has a velocity of at least 5, preferably at least 7 meters per second and an energy of at least 5000 joules, preferably at least 7000 joules, breaks the system and thus effectively restrains it.
  • the transparent plastic sheets of acrylic glass are known in the art. These plates can be cast, for example, from methyl methacrylate syrup. Typical pane thicknesses are 4 to 40 mm, preferably 12 to 25 mm. The discs are usually manufactured in a size of 1.5 m x 1 m to 2 m x 3 m, for special applications, larger or smaller versions are possible.
  • the discs are usually largely clear (transparent), preferably colorless or light, z. B. smoky brown, tinted.
  • the colorless, clear transparent plastic discs usually have a transmittance of at least 70%, advantageously a transmission of 90 to 95%.
  • Tinted finishes usually have a transmittance of 45 to 75%, usually between 50 and 60%.
  • plastic layer any polymeric material can be used, but the plastic layer must be distinguishable from the acrylic glass matrix surrounding the plastic layer. However, preference is given to plastics which are incompatible with the acrylic glass. Accordingly, polyamides, polyesters and / or polypropylenes are particularly suitable for producing the plastic layer.

Furthermore, the coefficient of thermal expansion of the metal should be in the range of that of the matrix plastic in order to avoid stresses due to temperature fluctuations.
  • the cross-sectional shape of the metal cord is not essential to the present invention. So ropes with round, oval, rectangular or square cross-section can be used.

  • the metal cable is completely surrounded or encased by a plastic layer.
  • the pull-out forces for the steel wire from the acrylic matrix are generally greater than 50 N, preferably greater than 100 N, without this being a restriction. This force is determined in a known manner by loading exposed metal cable with forces.
