Definitions

  • the invention relates to an element for soundproof walls and for cladding of concrete and rock walls according to the preamble of claim 1.
  • protective walls are used, for. B. of the type described in DE-OS 35 35 343. They consist of essentially U-shaped frames arranged one behind the other at intervals, which are connected to one another, for example, by means of longitudinal beams, tensioning cables or the like. Relatively close-meshed mats can be applied to the front and side surfaces of the U-shaped frames in order to keep soil material within the protective wall. Rigid frame-forming pedestals are provided for transport, so that a prefabricated protective wall can be loaded onto a truck and brought to the place of use despite the considerable weight by means of a lifting device.
  • DE-GM 78 33 360 describes a noise barrier for traffic routes and squares, which has a number of polygonal, elongated frames which are arranged at intervals from one another.
  • a scaffold constructed using spacers for the frames has, at least on the sides, walls which are suitable for plant growth and are permeable to water.
  • the frame, spacers and walls are made of rotting-resistant material, so that the limited space can be filled with soil and used plants can penetrate the walls.
  • this protective wall is somewhat simpler in comparison with the aforementioned construction and therefore cheaper to manufacture, the construction of the individual parts remains complex. Neither the assembly nor the disassembly of this noise barrier can be done in a modular manner. The dimensions are also relatively large and the transport costs are correspondingly high.
  • the invention aims to provide an element for effective erosion protection of over-steep slopes, concrete walls and the like, which should also be able to be planted permanently.
  • the invention proposes the features specified in the characterizing part of claim 1. Embodiments of the invention result from claims 2 to 20.
  • the invention it is possible to produce protective walls in a particularly advantageous manner, which ensure effective erosion protection of excessively steep embankments and their permanent greening.
  • the elements can also be assembled into frames in order to create any number of self-supporting step-shaped protective walls, which guarantee good noise protection and are also accessible to a variety of horticultural designs.
  • the inclination of the element or elements can be adjusted at the same time by means of the connecting or anchoring struts, as a result of which the structure can be optimally adapted to the local conditions.
  • the protective walls can be arranged in steps from the elements according to the invention in order to obtain so-called berms. H. horizontal or slightly sloping bank heels that are easy to plant and can collect rainwater.
  • integral or rigidly connected holding profiles are provided with the elements, which have fastening means for the struts, for example as specified in claims 3 to 5. Thanks to these measures, assembly and disassembly are quick and therefore inexpensive, while ensuring high strength at the same time.
  • each holding profile can have at least one outwardly projecting central region with adjoining side parts, which have inclined edges.
  • Such holding elements have particularly high stability in the embodiment according to claim 8. Its very narrow frontal surface appears only subordinate, which contributes to an advantageous street or landscape picture.
  • claim 9 is very advantageous, according to which the holding profiles are provided in the central region or on the end part with elongated recesses which, according to claim 10, are arranged in the grid dimension of the fleece or mat support parts.
  • rods can be inserted into the fillet of the holding profiles in order to secure the upstream nonwovens, nets, mats or the like from the inside and therefore inconspicuously. At the same time, this prevents a weakening that conventionally took place by cutting holes for plants.
  • the holding structure according to claims 12 to 14 is particularly advantageous in this regard.
  • the measure of claim 20 ensures high strength with minimal material expenditure and weight.
  • An element is a holding profile which can be produced from a galvanized sheet metal part according to FIG. 1.
  • side parts 14 adjoin on both sides, which are provided with beveled edges 16 at the top and bottom.
  • Fastening holes 18 with a preferably regular hole spacing M are provided parallel to the side edges running in the longitudinal direction L.
  • the central part 12 has recesses 20, which are designed as transverse, in particular rectangular, cutouts and are arranged in a longitudinal dimension L in a grid dimension D. Folding or folding in the central region 12 forms an outwardly curved end part 22, the inside of which forms a groove 60 (see FIGS. 2, 6, 7).
  • a backfilled humus substrate H is used by one in FIG. 3 schematically indicated fleece 30 held, which can also be a mesh or support fabric for the developing vegetation.
  • the holding profiles 10 which can be anchored to the base U by means of struts 24 (FIGS. 3 to 5) or enable the frame structure (FIG. 6).
  • the struts 24 are preferably designed as drawstrings and have at least one connecting part 26 with a screw hole 46 (FIG. 7).
  • the connecting parts 26 are fixed by a fastening discussed below on the holes 18 of the holding profiles 10. By suitable selection and dimensioning, the struts 24 determine the inclination of the holding profile 10 with respect to the underground U.
  • Mats 32 are used for external securing, the carrier wires 34 of which can be inserted into the recesses 20 as far as the end edges 42 thereof.
  • the grid dimension D is chosen equal to the standard distance of the carrier wires 34.
  • the latter are secured in their position by rods 28 which are introduced in the longitudinal direction L into the groove 60 in such a way that they can be supported or supported on both sides between the end parts 22 and the carrier wires 34.
  • the inclined edges 16 generally facilitate the attachment of the holding profiles 10 and also favor the support on a floor area or on berms, as can be seen from FIGS. 4 and 5.
  • the anchoring of the Stre ben 24 can be done both in rocky ground and on concrete walls B (Fig. 5) in a manner known per se, so that overgrown embankments with overgrown embankments can be produced quickly and reliably with the elements 10 according to the invention.
  • FIG. 6 A self-supporting arrangement can be seen in FIG. 6.
  • two pairs of elements 10a, 10b and 10c, 10d are each connected to one another by struts 24, a central strut allowing an angled transition.
  • the individual elements 10 can have 36 hole pairs 38 in a corner or edge region, which have corresponding screw holes 46 of the central strut 24 match.
  • the latter is trapezoidal, so that the lower pair of elements 10c, 10d protrude beyond the upper pair of elements 10a, 10b.
  • the length of the lowest strut 24 determines the inclination or the angle of repose of the lower elements 10c, 10d.
  • All of these elements can in turn be filled with suitable material behind (not shown) nonwovens, with structural steel mats for securing, of which only support wires 34 are indicated in the upper left in FIG. 6, which in turn are inserted in the longitudinal direction L in front of the fillets 28 60 of the end parts 22 are held.
  • FIG. 7 illustrates an advantageous fastening of an element 10, the side parts 14 of which are connected to a strut 24 via the connecting part 26 thereof.
  • the front part 22 projects through a double mat arrangement 32, the carrier wires 34 of which are secured against slipping through by welded flat iron 58 and are additionally strengthened with each other by means of holding wires or rods 40.
  • the rods 28, which are inserted into the fillet 60 in front of the carrier wires 34, are used for bracing.
  • the connecting part 26 of the strut 24 is fixed to the holding profile 10 according to FIG. 7 by means of a socket screw or a bolt 44 which passes through the fastening holes 18, 46 and is screwed tightly by means of a locking washer 50 and nut 52.
  • a plurality of screw holes 18 and 46 can be provided in a suitable arrangement in order to selectively effect optimal connection of the struts 24 to the elements 10.
  • spacer sleeves 48 ensure that the side parts 14 of the holding profile have a preselected minimum distance at the connection point. This is at least as large as the width of the front part 22 when the element 10 is designed as a U or V profile.
  • FIG. 8 to 10 show construction examples for frame R in the manner of FIG. 6. It can be seen that these frames R can taper pyramid-shaped, the length of the struts (not shown here) the inclination or. Slope angle of each pair of elements 10 is determined.
  • the backfill with the humus substrate H, from which the greenery G grows, is secured by fleeces and mats 32.
  • this hollow profile 10 can be produced from a flat sheet metal section, the recesses 20 and the designs for the rod 28 being formed by tube sections which are welded to the metal sheets at the predetermined distance 20 from one another on the end face.
  • the remaining design of the holding profile can be retained, in which case the strut or the tension band 24 is screwed on one side to the sheet metal in the fastening holes 18.
