  • a noise protection element comprising a stone basket or a gabion of sheet-like grid elements and at least one further sound-absorbing layer or another sound-insulating and / or sound-insulating element, projecting on the end faces of the noise protection element or protruding out of the plane protrusions are formed and formed so that they are suitable in double-T or I-shaped Profiles of uprights or vertical beams, such as HEA, HEB or HEI-posts, a noise barrier to intervene.
  • the combination of the stone basket filled with stones with the additional sound-absorbing and sound-absorbing insulation element also increases the noise protection effect, especially against the passage of sound.
  • this noise protection element is due to the special design of the faces suitable to be quickly and easily assembled to a safe standing noise protection wall.
  • the structure is carried out so that first the pillars are placed and then the individual noise protection elements are pushed from above between the pillars, whereby the bulges are guided in the profiles and in this way a mechanically stable noise barrier is obtained.
  • the noise protection element according to the invention thus fulfills a multiple function.
  • noise protection elements do not all have to be grounded in, but only the posts must be firmly anchored in the ground. The subsequent insertion of the noise protection elements is then quickly and easily possible. Even an exchange of damaged or unsightly become noise protection elements is easily possible or could in extreme cases even only the stones are replaced.
  • the end faces are formed from continuous, warp-resistant profiles. In this way, an insertion of the noise protection elements in the uprights is more easily possible or the noise protection elements are thus more stable and torsionally rigid, whereby the overall stability of the noise barrier is increased.
  • the bulges extend over the entire height of the noise protection element or the end faces, whereby a facilitated insertion into the profile uprights and improved grip is made possible.
  • the bulge has a front surface that is oriented perpendicular to the extent of the noise protection element, in particular flat, front surface. This also allows good guidance and facilitates the construction of the noise barrier.
  • the end faces have at least one step or bending edge, whereby the rigidity of the noise protection element is increased.
  • a noise protection element for example, also easily factory filled with stones and can then be transported to the place of need.
  • the bulge has a substantially rectangular cross-section, as a good guide in the profile of the uprights is ensured and the bulge is supported on all sides by the surfaces of the stand, in particular stabilized against the wind load acting laterally ,
  • the terminal edges of the Dämmelements and possibly portions of the stone basket protrude into the interior of the respective bulge.
  • all cavities of the noise protection element are filled as completely as possible, whereby the structural stability is increased.
  • the soundproofing effect is increased.
  • the terminal edges of the Dämmelements are spaced from the inner surface of the front front surface or not quite protrude to this front surface, whereby a free space is formed in this area.
  • structural tolerances can be considered or tolerated the noise barrier thermal length changes or certain distortions of the terrain and retains some flexibility.
  • the transport bracket of the respective lower noise protection element in this free space of each upper and disappear therein thereby ensuring a secure and accurate engagement of the noise protection elements in each other, which also flush the side surfaces flush with each other and a flat uniform side surface arises.
  • an exact alignment of the bars is ensured to each other, whereby the vertical grid lines do not move away across all noise protection elements, but the grid lines are visually appealing with each other.
  • a space-saving and compact form of a noise protection element is ensured by the fact that the insulating element is aligned parallel to the visible surfaces of the grid elements.
  • a preferred embodiment of the noise protection element is characterized in that the insulating element inside the stone basket is arranged invisibly from the outside after filling or is surrounded by it on both sides, wherein the noise protection element is frontally bounded by the end faces and the visible side of the flat grid elements of the stone basket.
  • Such a noise protection element is optically appealing on both sides and at the same time stable, as well as acoustically advantageous.
  • the insulating element is arranged in the interior of the noise protection element laterally next to, in particular parallel to, stone basket.
  • the noise protection element is frontally bounded by the end faces, on the one visible surface of the flat grid element of the stone basket and on the opposite visible surface of the insulating element.
  • Such a noise protection element is somewhat space-saving and narrower, but nevertheless visually appealing on one side by the stone filling.
  • the two end surfaces and a visible surface merge into a unit or to a common profile, whereby an integral, continuous, torsionally rigid wall element is formed, which extends from the one end face to the opposite end face or includes these two faces and the longitudinal side follows the course of the Dämmelements.
  • the noise protection element is thus limited on the one visible surface of the flat grid element of the stone basket and on the opposite viewing surface and on the end faces by the wall element.
  • the insulating element of two or more parallel to each other and in particular contacting contiguous layers of different insulating and / or absorbing materials is formed.
  • a noise protection wall can thus be constructed in a modular manner by arranging the individual noise protection elements, in particular on the front side, against one another and optionally also one above the other.
  • the noise protection elements are pushed or arranged between the double-T or I-shaped uprights and are held by the profiles of the uprights in their position and secured against falling out.
  • a first preferred embodiment of a noise protection element is shown, which is inserted between two double-T or I-shaped vertical beams or stators 11.
  • the noise protection element 1 and the uprights 11 are components of a noise protection wall 10, wherein the noise protection wall 10 is modularly constructed from these elements.
  • Each noise protection element 1 comprises a stone basket or a gabion or ballast 2, which comprises two opposite planar grid elements 6, which in turn are each formed of two sets of perpendicularly aligned wires or metal rods. Above and below the stone basket 2 is also limited by grid elements 6. In the cavity formed thereby stones or sound-insulating materials, such as lava rocks, can be filled. This has both a visually appealing effect, as well as a certain sound-absorbing effect.
  • a further sound-absorbing and sound-absorbing insulating element 3 is provided in the interior of the stone basket 2, which in the present embodiment consists of two mutually parallel and touching contiguous layers 3 'and 3 "of different acoustically favorable materials become.
  • bulges 5 extend unchanged and uniform over the entire height of the end faces 4, have a substantially rectangular cross-section and have a perpendicular to the longitudinal extent of the noise protection element 1 aligned forwardmost front surface 8.
  • the bulge 5 is symmetrical to the median plane of the noise protection element and formed by two steps or folding edges 9 in the form of a middle-flush elevation of the end face 4.
  • the end faces 4 are formed of continuous warp-resistant steel profiles of sufficient strength, which additionally increases the stability.
  • the end faces 4 are fixedly connected at their side edges with the grid elements 6, for example by latching hook-shaped elements of the grid elements in recesses of the end face 4.
  • cross struts 15 may be provided which connect the opposite grid elements 6 of the stone basket 2 with each other tensile strength and prevent buckling. These cross struts 15 enforce the Insulating element 3 through through recesses 16, which in turn sound-proofed, in particular foamed, are.
  • the two sound-absorbing layers 3 ', 3 "of the Dämmelements 3 protrude into the interior of the respective bulge 5, but not quite up to the inner surface of the foremost front surface 8. Between the foremost front surface and the end edges of the Dämmelements 3 is thereby a small cavity or A free space 19, which extends over the entire height of the noise protection element, is formed, in which free spaces 19 the transport brackets can engage.
  • the sound-insulating layers 3 ', 3 are fitted snugly fit in the bulge 5, wherein on both sides support elements 14 are provided to prevent slipping or to fix their position.
  • the present noise protection element 1 is thus frontally bounded by the two end faces 4 and the visible side of the two opposing grid elements 6 of the stone basket 2.
  • the internal insulation element 3 is no longer visible after filling with stones or surrounded on both sides by the stone basket 2.
  • Fig. 2 It can also be seen how this noise protection element 1 is inserted into the profiles of the uprights 11.
  • Each upright 11 has a double-T or 1-form, in particular according to the standard HEA, HEB or HEI, wherein the bulge 5 is fitted into the corresponding recess of the profile carrier or riser 11. In general, this is done by inserting from above between two opposite uprights 11. This leaves a small distance between the front front surface 8 and the middle part of the post, which provides a certain margin of tolerance and facilitates installation.
  • this noise protection element 1 differs from that described above in that the insulating element 3 is not arranged inside the stone basket 2, but laterally adjacent to the stone basket 2 or parallel touching the stone basket 2 touching or a side wall of the stone basket ( 2).
  • the noise protection element 1 is thus frontally bounded by the two end faces 4 and on its one visible surface of the flat grid element 6 of the stone basket 2, but on the opposite visible surface 7 of the insulating element 3.
  • This embodiment is thus indeed narrower or lesser in thickness, but only a visually appealing steinveryogllte page on, but this is sufficient for many requirements.
  • a continuous wall element 12 in the form of a large-area steel profile is also provided in this embodiment, which extends from the one end face 4 to the opposite end face 4 and these end faces 4 also mitumutzt.
  • Such a noise protection element 1 is thus surrounded on at least three side surfaces of this one-piece solid steel profile 12 and only on the front visible surface and optionally on the top of the flat grid element 6, through which the stones are visible. In this way, the stability is additionally increased.
  • a single insulating element 3 is provided from a single insulating material.
  • a plurality of contiguous insulating elements 3 or layers can be provided without any problems.
  • This insulating element 3 also extends over the entire length of the noise protection element 1 into the two bulges 5 inside.
  • bulges 5 are also rectangular in cross-section, but only one step or bending edge 9 is formed in the end surfaces 4.
  • One of the side surfaces of the bulge 5 thus forms part of the visible surface 7 or runs flush and level with this, which, however, is necessarily given by the fact that it is the one-piece continuous wall element 12.
  • the stone basket 2 or the cavity into which the stones are fillable extends in some areas also into the bulges 5 and can be filled almost to the edge.
  • transport bracket 17 may be provided, whereby the individual noise protection elements 1 can be lifted and transported both in the empty and in the already filled state.
  • the transport bracket 17 are attached to the inside of the front surface 8 and arranged so that when stacking several noise protection elements 1, the transport bracket 17 of the respective lower noise protection element 1 protrude into the free space 19 of each upper noise protection element 1 and disappear. This ensures a secure and precise engagement of the noise protection elements 1 into each other, whereby the end faces 4 flush with each other and a flat uniform side surface is formed. In addition, this ensures that the vertical bars are aligned with each other always aligned and creates a visually consistent image.
  • a further possible embodiment of a noise protection element 1 is characterized in that the stone basket 2 is subdivided into three equally large spaces which are adjacent to one another and respectively separated from one another by grid elements and in each of these spaces a further sound-absorbing and / or sound-absorbing insulating element 30 is arranged , The two outer insulating elements 30 protrude into the bulges 5.
  • the middle insulating element 30 is thicker than, in particular twice as thick as, the two outer insulating elements 30.
  • a noise protection wall 10 is constructed according to the invention of a larger number of such noise protection elements 1 and intermediate stators 11 modular, the noise protection elements 1 are each placed between two uprights 11 frontally to each other.
  • the structure is usually carried out so that first the uprights 11 are placed, with their recesses of the double-T profiles face each other.
  • the spacers 11 each form a snug fit for the bulges 5.
  • the distance between these posts 11 is slightly larger than the length of the noise protection elements 1.
  • concrete elements are first inserted between the uprights 11, which form the ground-level base.
  • the noise protection elements 1 are placed with a crane between the uprights 11 and lowered from above, that the bulges 5 reach into the recesses of the profiled uprights 11.
  • the path of the noise protection elements 1 is specified for the further lowering process and the noise protection elements 1 are secured against falling out, pressure and train.
  • the noise protection elements 1 seals 18 may be provided to further reduce the passage of sound.
  • several noise protection elements 1 can be arranged one above the other.
  • the interspaces are filled with polymers.
  • Such a noise barrier 10 corresponds acoustically to the standards ⁇ NORM EN1793-1 and -2 and meets not only the sound requirements, but also the structural and stability requirements, such as the static requirements and resistance to weather, wind, deicing salts or exhaust gases.
