Definitions

  • the invention relates to a stone basket for creating a soundproof wall according to the preamble of patent claim 1.
  • This stone basket consists of wire mesh walls, which are held together. In the interior of these wire mesh walls another wire mesh wall is provided, which divides the stone basket into different departments. In this case, the larger compartment with stones and the smaller compartment with a noise insulation material, in particular foam glass ballast be filled.
  • a built with these known stone baskets soundproofing is characterized by a low reflectance, the direct sound transmission is only insufficiently damped.
  • the invention has for its object to provide a stone basket of the type mentioned, which is characterized by a low Schallreflexions- and transmissivity.
  • the stone basket according to claim 1 is used to create a sound barrier, which dampens a sound source.
  • Other applications of this sound barrier are possible.
  • the stone basket is formed by wire mesh walls, which form a solid framework of the stone basket. These wire mesh walls hold the rickety contained therein together, so that the soundproofing wall remains in shape.
  • the interior of the wire mesh walls is divided into at least two compartments filled with bulk material. At least the remote from the sound source department is filled with stones, which contribute substantially to the formation of sufficient mass and stability of the stone basket.
  • a transmission barrier This consists of a substantially air-impermeable, solid plate. This plate dampens the passage of sound waves through the rock fill due to diffraction effects in the voids between the individual stones.
  • the solid plate forms one for air vibrations Barrier, so that the sound waves can not use a direct connection between the sound facing and the remote side of the stone basket. It is particularly important that the riprap is applied to the transmission barrier, whereby a sound transmission is reliably suppressed by vibrations of the entire plate.
  • the formation of the transmission barrier as a solid plate also helps to prevent vibrations of the entire plate, which could contribute to the sound transmission.
  • the transmission barrier results in a sufficiently low sound transmission, as a result of the riprap and the sound reflection remains sufficiently low. This would not be the case when using the solid plate without the riprap, as this would have too high a sound reflection values. In addition, the problem of the generation of vibrations of the plate in this way would no longer be manageable.
  • the transmission barrier has slots into which engage the bars of the wire mesh walls. The transmission barrier passes through the wire mesh walls, so that it protrudes on the outside over the wire mesh walls. Thus, the transmission barrier also covers an area around the stone basket, whereby the transmission barriers of adjoining stone baskets may possibly overlap. Thus, the area between the stone baskets is covered by the transmission barriers, so that at these points virtually no sound transmission is possible. This results in particularly low sound transmission values of the soundproofing wall.
  • the transmission barrier substantially fills the stone basket. This may result in only small gaps between adjacent stone baskets, which are permeable to sound directly. By far the largest part of penetrating into the stone basket sound waves is reliably attenuated by the transmission barrier.
  • the transmission barrier has profile strips which are held on the wire mesh walls. This profile strips are provided with the slots and thus cover the gaps formed between the lattice walls and the transmission barrier, so that virtually no sound transmission is given within the individual stone basket.
  • the moldings L- or U-shaped.
  • the basket interior directed to the legs of the profile strips can detect a separate plate of the transmission barrier area, so that a substantially soundproof connection of the transmission barrier is given to the legs of the moldings. This measure thus increases the attenuation of the sound waves in transmission.
  • the profile strips are connected to a plate, which together form a trough.
  • This tray may optionally accommodate a separate plate of the transmission barrier and protects it in particular in the sensitive end face area.
  • the transmission barrier can be very easily handled in this case and placed in the basket.
  • the plate is made in one piece with the profile strips, so that there is a simple and thus cost-effective creation of the tub.
  • it is thought to manufacture the tub as a sheet metal part.
  • the transmission barrier is well held within the tub, it is also intended to bend the profile strips on the opposite side of the plate inward. In this way it is achieved that the transmission barrier is included in the edge region of three sides.
  • the transmission barrier wood plastic or metal have been proven according to claim 7.
  • metal in particular a ferrous material is used, since this material is characterized by a high density, Shape and weather resistance distinguishes. Since the transmission barrier has no supporting function, corrosion effects in the transmission barrier play no role.
  • the transmission barrier has a high basis weight. At a weight per unit area of at least 2 kg / m 2 , together with the ridge facing away from the sound, there is a sufficient blocking effect for continuous sound waves. With a weight per unit area of at least 7 kg / m 2 , the transmission barrier itself already provides a sufficiently high blocking effect for continuous sound waves, so that the entire blocking effect of the stone basket no longer has to be checked on a case-by-case basis. This considerably simplifies the handling of the stone baskets.
  • the transmission barrier is associated with an absorber plate having a lower density than the transmission barrier.
  • This absorber plate ensures with its low density for effective sound absorption, so that the risk that the transmission barrier is in vibration, is reduced accordingly. In this way, the soundproofing of the stone basket improves considerably.
  • the absorber plate consists of pressed natural fibers.
  • the absorber plate can also be formed from a polymer foam, such as foamed polystyrene.
  • a closed-cell polymer foam is used to prevent the penetration of water into the absorber plate. Due to the amount of gas introduced into the absorber plate, there are considerable local density differences within the absorber plate, which lead to an effective sound absorption.
  • the absorber plate is defined on the sound source side on the transmission barrier.
  • the transmission barrier additionally stabilizes the absorber plate, so that vibrations of the absorber plate are further weakened due to penetrating sound waves.
  • the stone basket can be very easily produced in this way, since before filling the stone basket only provided with the absorber plate transmission barrier must be introduced into the stone basket.
  • the transmission barrier and possibly the absorber plate is under the contact pressure of the stone filling and is stabilized in this way and at the same time protected against environmental influences such as light, moisture, storm and wind.
  • the sound source facing department filled with stones of lesser, medium size than the sound source remote department it is advantageous if the sound source facing department filled with stones of lesser, medium size than the sound source remote department.
  • the smaller stone size on the sound side results in correspondingly smaller spaces between the stones, which leads to an effective sound pickup in the riprap.
  • the size of the stones is adapted to the frequency of the shielded sound source, the stone size is chosen to be smaller, the higher frequency is the incident sound.
  • a stone basket 1 according to FIG. 1 consists of wire mesh walls 2, which enclose an interior 3 on all sides.
  • a transmission barrier 4 is held in the form of an iron plate.
  • an absorber plate 5 is glued sound source side.
  • the absorber plate 5 consists of a closed-cell polymer foam, in particular polystyrene foam.
  • the transmission barrier 4 and the absorber plate 5 divide the interior 3 into two compartments 6, 7.
  • the stone basket 1 is irradiated on one side by a sound source 8 shown only symbolically and is intended to reflect or transmit as little as possible the sound waves emanating from the sound source 8.
  • a sound source 8 shown only symbolically and is intended to reflect or transmit as little as possible the sound waves emanating from the sound source 8.
  • a riprap in the form of two consecutively arranged layers 9, 10 is filled in the sound source 8 facing department 7 of the stone basket 1 .
  • the stones 11 of the inner layer 10 have a smaller size than the stones 11 of the outer layer 9. In this way results in an effective attenuation of the outgoing sound source 8 sound waves in a wide frequency range.
  • the sound source 8 facing away from department 6 is filled with stones 11, the relative are big. These stones 11 serve primarily to achieve a sufficient stability of the stone basket 1.
  • the rock fillets 11 in the two compartments 6, 7 press directly against the transmission barrier 4 and the absorber plate 5 and stabilize and protect them.
  • the transmission barrier 4 on projecting moldings 12.
  • FIG. 2 shows a sectional view through a transmission barrier 4.
  • the profile strip 12 is basket inside U-shaped, legs 13, 14 lie flat against a plate 4 'of the transmission barrier 4 and the absorber plate 5.
  • the legs 13, 14 engage over the plate 4 ', so that no gap between the plate 4' and the wire mesh wall 2 is formed. This improves the transmission barrier effect of the stone basket 1.
  • FIG. 2 shows on the right side an alternative embodiment of the transmission barrier 4.
  • the profile strips 12 are integrally connected at the rear with a plate 17 so that they together form a trough. This trough essentially forms the transmission barrier 4.
  • a web 15 is integrally formed on the profile strip 12, which is arranged offset with the web 15 of the adjoining stone basket 1. This is achieved by off-center attachment of the web 15 on the profiled strip 12. This overlap the webs 15 abutting stone baskets 1, so that in the connection area the stone baskets 1 is an effective barrier to penetrating sound waves.
  • FIG. 3 provided with slots 16 in the region of the webs 15. These slots 16 are adapted to the wire mesh walls 2, so that the web 15 of the profile strip 12 can penetrate the wire mesh wall 2.
  • FIG. 4 an alternative embodiment of a stone basket 1 in sectional view.
  • like reference numerals designate the same parts, wherein in the following only the differences from the above-described embodiment will be discussed.
  • the profile strip 12 of the stone basket 1 is U-shaped, wherein the two legs 13, 14, the plate 4 'and the absorber plate 5 detect.
  • the web 15 is aligned parallel to the plane of the wire mesh wall 2 in contrast to the above-described embodiment and consists of an elastic material. In particular, it is intended to foam rubber, rubber or silicone rubber.
  • This web 15 forms a seal between the rails 12 adjoining stone baskets 1.
  • the web 15 can be fixed directly to the rail 12, in particular be glued. Alternatively, the web 15 could also be subsequently introduced between the stone baskets 1, before they are pulled together.
  • the particular advantage of this embodiment is that the webs 15 protrude only slightly above the wire mesh walls 2, which significantly improves the stackability of the individual stone baskets. Due to the formation of the webs 15 made of an elastically yielding material, a sufficient soundproofing nevertheless results in the gap region between the stone baskets 1. Alternatively, the plate 4 'could also be provided with the slots 16.
