Definitions

  • the invention relates to a plantable noise barrier, in particular for shielding highways, railways and industrial noise sources, in which at least the surface of the noise barrier facing the noise source is inclined from its crown towards the noise source, with holding structures arranged in parallel and spaced apart, between adjacent ones Retaining structures Planting rib boards are arranged obliquely and their ends can be inserted into the retaining structures at least in the areas of the retaining structures facing the noise source.
  • the wooden support structures for the ribbed planks are designed as a scaffold consisting of several, approximately vertically arranged, wooden posts inserted into a concrete foundation, which are connected to one another by longitudinal and transverse struts.
  • the wooden posts have oblique grooves into which the ribbed boards are inserted.
  • the scaffold is filled with potting soil from above, depending on the type of potting soil used, the inner surface of the scaffold is covered with a coarse-mesh mat.
  • the noise barrier mentioned has proven itself in practice, it still requires considerable design effort, which has an unsatisfactory effect, in particular, when the noise barrier is installed.
  • the individual wooden posts are to be aligned exactly, the longitudinal and transverse struts are to be connected to them using separate fasteners. Because of the small footprint of the wooden posts, a concrete foundation is required as a base for the scaffolding.
  • the wood used has also proven itself, in particular the individual parts of the scaffold are easy to handle due to their relatively low weight, and their high price is disadvantageous.
  • plastic enables simple and inexpensive production of homogeneous components which are advantageously pressed or cast in molds.
  • plastic for example, polyethylene comes into question, as well as plastics based on recycling.
  • the pane according to the invention can be designed as a flat plate or consist of several plate-shaped pane parts placed one above the other, each of which is provided with the slots for receiving the planting rib boards. If sufficient stability of the disk is ensured, it can additionally be provided with one or a plurality of recesses; in extreme cases, only one annular surface remains which receives the slots at least in the area facing the noise source.
  • the hitherto known cross struts or other support components are eliminated by the design of the holding structure in the manner of a one-piece or multi-piece, frame-like disk.
  • An essential element of the present invention lies in the plug connection of the planting rib boards with the corresponding slices or slice parts.
  • the planting rib boards also serve to fasten the disks or disk parts without requiring special fastening means between the planting rib boards and the disks or disk parts.
  • panes or pane parts are arranged adjacent to one another and the planting rib boards are inserted into their slots. Subsequently, the space between the panes or pane parts is filled with planting earth before, in the event of the noise barrier being formed by a plurality of pane parts arranged one above the other, the next pane parts are placed and the planting rib boards are inserted into them, as well potting soil is filled up again, etc. until the complete noise barrier is formed after the uppermost pane parts have been put on.
  • the weight acting on the ribbed boards when the noise barrier is filled with potting soil further increases stability.
  • the noise protection wall formed from the ribs and the panes stands by itself, so no concrete foundation is required to fix the panes, it is only necessary to ensure that the soil is compacted so that the noise barrier does not sink. Due to the immediate support of the noise barrier on the ground, the poured earth of the noise barrier grows with the topsoil, so that the topsoil forms a unit with the poured earth and additionally stabilizes the planted noise barrier.
  • the connecting function of the planting rib boards with the slices takes place in the simplest way by the formation of the cross-section which is tapered in relation to the other cross section of the respective planting rib board, so that the thicker end engages behind the respective pane through the slot.
  • the present invention relates to a noise protection wall in which at least the surface of the noise protection wall facing the noise source is inclined from its crown toward the noise source.
  • the noise barrier can thus be designed both as a retaining wall integrated into an embankment, in which the plant rib boards are provided only on the surface facing the noise source, and also free-standing, in this case the plant rib boards are assigned to the surface facing and facing away from the noise source, the latter surface from the Crown of the noise barrier is inclined away from the noise source. Due to the inclination of the surface, natural irrigation is absorbed, so that the noise barrier can be greened without artificial irrigation.
  • the inclined surfaces convex or concave it is crucial that the crown width of the noise barrier is smaller than the contact width.
  • Optimal irrigation results can be achieved if the disc has the shape of a trapezoid, in particular an isosceles trapezoid, and the planting rib boards are arranged in both leg regions of the disc.
  • a particularly simple connection of the disc and planting rib board results if the slot in question is T-shaped, the bar of the slot having a slightly larger cross section than that of the respective end of the planting board and the butt joint of the slot of the slot having a width has, which is slightly larger than the width of the tapered cross-sectional area of the ribbed board.
  • the end of the ribbed planting board is pushed into the beam of the slot until the tapered cross-sectional area can be moved into the web of the slot.
  • a second planting board connected to another neighboring pane can be inserted into the same slot and secures the planting board previously inserted into the web are stored in the same slot, due to the almost identical points of attack of the plant rib boards on the disc, no significant bending moments are introduced into it.
  • each planting rib board should have a reinforcement extending perpendicular to the large board surface between the tapered areas located at both ends, the cross section of the reinforcing rib increasing in accordance with the bending moment line of the planting rib board to the center of the board.
  • the reinforcing rib is advantageously arranged on the top of the planting rib board in the region of the longitudinal edge adjacent to the interior of the noise protection wall. Due to their arrangement in the pressure zone of the planting rib board, the poured soil is retained on the one hand, on the other hand, with optimal stability of the planting rib board, the underside can be flat, the projected area of the respective planting rib board is minimal and the sound waves essentially hit the highly absorbent Medium earth / plants on.
  • support elements can also be provided, each of which engages under the upper plant rib board, in particular in the region of its center, and is supported on the plant rib board or floor located underneath.
  • the support elements can be firmly connected to the underside of the planting rib boards and can be inserted into the upper side of the planting rib board located underneath.
  • You can also form a board-shaped carrier with slots, thus a kind of rack, which is supported on the ground and with its slots receives the ribbed boards.
  • a diagonal spar which can be positively connected to it is arranged between adjacent panes or pane parts.
  • the respective end of the diagonal spar can be inserted and connected in accordance with the plant rib board into the pane or the pane part, without the need for additional fastening means.
  • the noise barrier shown in FIG. 1 essentially consists of one-piece disks 1 and planting rib boards 2 connecting adjacent disks 1.
  • Each disk 1 has the shape of an isosceles trapezoid, a trapezoidal opening 4 is provided symmetrically to the central axis 3.
  • the length of the lateral pane edges extend perpendicular to these projections 5.
  • the two leg regions 6 and 7 of the pane 1 remaining between the projections 5 and the recess 4 each have rows of slots 8 consisting of six slots 8. As can be seen in particular from the illustration in FIG. 5, the rows of slots run parallel to the shoulders 5 at an angle ⁇ of 10 ° to the vertical.
  • Each slot 8 is T-shaped, the bar 9 of the slot 8 in question having a slightly larger cross section than that of the respective end 10 of the planting rib board 2 and the web 11 of the slot 8 butting the middle of the bar 9 having a width, which is slightly larger than the width of the tapered cross-sectional area 12 of the planting rib board 2.
  • the depth of the web 11 corresponds approximately to twice the thickness of the end 10 of the planting rib board 2.
  • the beam 9 of the slot 8 is inclined upwards with its end facing the shoulder 5, the angle of inclination ⁇ is 45 ° to the horizontal.
  • the respective wind bandage is assembled by first inserting the downward-facing lugs 19 into the vertical leg 21 of the corresponding holes 20, and then pulling the spar 18 into the horizontal leg 22 with a rotational movement of 90 ° until it is laterally on the Disc 1 rests and the nose 19 engages behind the disc 1.
  • FIGS. 1 and 5 to 8 illustrate the advantages which can be achieved in the noise barrier according to the invention by the position of the planting rib boards in the panes and relative to one another and the design of the planting rib boards.
  • the individual planting rib boards have such a free distance from one another that the lower edge 24 and the upper edge 25 of two adjacent planting rib boards 2 lie approximately on the cutting cone line 26 of the earth filling, which extends at an angle ⁇ of approximately 45 ° to the horizontal.
  • the planting soil can thus be kept open in the noise barrier, the reinforcing ribs 16 arranged in the region of the lower edges 24 of the planting rib boards 2 not only serving to increase the section modulus of the reinforcing rib but also holding back the planting soil. Due to the large number of ribbed planks and their position in relation to the sound source, a surface structure with a high degree of delicacy and various inclined planes is achieved, whereby large surfaces facing the sound source consist of the highly absorbent medium earth / plants.
  • the second embodiment differs, as can be seen from FIGS. 9 and 10, by the horizontal subdivision of the disk 1, which has the shape of an isosceles trapezoid, into the disk parts 1b, 1c, 1d and 1e, which also has the shape of an isosceles trapezoid.
  • the disc parts are each provided on their undersides with a groove 30, in which a spring 31 arranged on the disc part located underneath and on the upper side thereof engages. This is shown by way of example for the disk parts 1b and 1c in FIG.
  • the space formed between the disc parts 1c is then filled with planting earth in the manner described, the further side parts 1d and then 1e are subsequently placed as described, by dividing the disc 1 into several disc parts 1b to 1e to form the Noise protection wall only requires a few parts that are justifiable for a modular system.
  • the pane parts which have the small height dimensions serve for the exact height adjustment of the noise barrier to a predetermined height.
  • the single ones Window parts can be connected to each other in different ways. A tongue and groove connection is not absolutely necessary; the connection can also be made, for example, by means of clamping elements which overlap adjacent pane parts.
  • the planting rib boards 2 are flat, they thus correspond to the ones shown in FIGS. 2 to 4, but the reinforcing ribs 16 that reduce the deflection are missing.
  • a board-shaped support 32 is also included Slits 33 provided, the carrier is supported on the ground and receives with its slots 33 in the slot thickness adapted plant rib boards 2.
  • the carrier 32 can be formed in one piece, as shown in FIG. 9 or in several parts, as illustrated in FIG. 11, where a number of support elements 34 and 34a corresponding to the number of planting rib boards 2 accommodate the planting rib boards in the slots 33.
