Definitions

  • the invention relates to a noise protection device according to the preamble of claim 1, an individual element for producing the noise protection device and a noise protection wall formed from the noise protection devices according to the invention.
  • a soundproof wall is known, the individual elements of which - in order to simplify assembly in each case - are formed in one piece with an anchoring part.
  • the depth of use of these anchoring parts depends on the expected static load.
  • a support rib is also provided to improve the static properties.
  • Butting elements can be connected to each other with stainless steel clamps and joint seals to increase the stability of the soundproof wall.
  • They are individually reinforced by horizontal and vertical metal reinforcements. Therefore, in addition to the anchoring part, reinforcement devices are arranged both within the individual elements and between them.
  • DE-OS 27 21 408 proposes a noise barrier with easier installation for streets and airfields, which consists of open-pore lightweight concrete slabs. Each of these plates is framed by vertical iron girders and cross girders connecting the latter. The secure hold of the panels and the particularly favorable static properties of the noise barrier are based on this border.
  • the panels can be produced in series and, after the steel girders have been installed, can be joined together to form a noise barrier. In order to achieve sufficient sound insulation and stability, the joints between the steel beams and the panels or between the panels are filled with mortar compound after assembly, the hardening of which only ensures full resilience.
  • the lightweight concrete slabs can be profiled on one side.
  • the object of the present invention is to propose an economically advantageous noise protection device that can be used in a short time and without any special effort to noise barriers, especially along traffic routes, and can be fully loaded immediately after installation.
  • the noise protection device according to the invention should in particular also withstand the increased load caused by superfast trains (TGV).
  • Another object of the invention is to provide a noise protection device which has two profiled sound absorption surfaces, the profile patterns of the two sound absorption surfaces being independent of one another and being able to be varied within the same surface.
  • the inventive noise protection device with several interconnected individual noise protection elements, which are penetrated by at least one prestressing element, represents a finished partial area of a noise protection wall that can be immediately loaded after assembly from the individual elements, for example at the construction site.
  • the interaction of the connections between the individual elements with the preferably Preloading elements arranged parallel to each other not only ensure the static stability of the individual noise protection device within the noise protection wall, but also allow easy manipulation of the noise protection device before and during installation.
  • the latter is additionally facilitated by at least one pretensioning element projecting beyond the noise protection elements, wherein the protruding part forms a kind of handle.
  • two vertical prestressing devices are provided on average per noise protection device. These are arranged in mutually aligned recesses in the soundproofing elements.
  • the space between the prestressing element and the recess wall can be filled with a casting compound.
  • a further improvement of these properties can be achieved by filling the holes or recesses not occupied by a prestressing element with a casting compound made of a hydraulic binder or plastic.
  • horizontal prestressing members can be provided. In this case, corresponding recesses must of course be provided.
  • noise protection device Another advantage of the noise protection device according to the invention is that the noise protection elements used for its production are based on already existing ones Equipment for the production of building materials can be produced.
  • the noise protection elements can contain a binder and an aggregate with a cell structure, the aggregate particles preferably being exposed on the surface of the element which is exposed to noise.
  • the manufacture of elements with exposed aggregate particles is known, e.g. from CH-PS 660 609.
  • Hydraulic binders such as cement, gypsum and slaked lime and plastics are preferably used as binders.
  • Porous granules e.g. Expanded clay, pumice, lava slag, and glass foam or other materials with a cellular structure, e.g. Wood shavings.
  • Threaded tension rods made of steel are suitable as pretensioning elements, which are held in their two end regions, for example with a plate and a nut, on the noise protection element with compressive stress.
  • Such threaded tie rods are sold, for example, by the company SpannStahl AG, Hinwil (Switzerland).
  • the noise protection elements 1 and 1 'in Figures 1 to 3 and 8 to 10 have on their side facing the noise or the main noise sources 2, which are also referred to as front sides, vertical, tapering ribs 4 to increase the sound absorption.
  • the rib spaces 6 are correspondingly tapered inwards.
  • These ribs 4 are also bevelled and chamfered at their upper end 8 (only in Figures 1 to 3).
  • an inwardly tapering recess 14 is arranged, in which an opposite projection 16 of the next noise protection element 1a and 1a 'engages. Between the recess 14 and the projection 16 there is an intermediate space 15 for receiving, for example, a mortar compound.
  • the two abutting abutment surfaces 12, 12a each have a recess 18, 20 in their center on, which together form a through hole 22 with an oval or square cross section.
  • an inwardly tapering horizontal recess 28 is arranged, which serves to hold a binder mass, for example mortar.
  • the noise protection element 1 'in Figures 8 to 10 has on its side facing away from the main noise source or rear 3 vertical ribs 5 tapering towards the front. These have a lower height than those on the front. Corresponding gaps 7 are arranged between the ribs 5. Of course, the height of the ribs can be freely selected according to the respective needs.
  • the inventive noise protection device 30 in FIG. 4 is composed of noise protection elements 1 according to FIGS. 1 to 3 which are connected to one another and connected to one another with a two-component adhesive.
  • a mortar compound can also be used. Eight such elements are arranged here in a horizontal row and seven elements arranged one above the other form a vertical row. The section of Figure 4 goes through a horizontal row, which is, however, only partially shown.
  • the two tie rods shown pass through the aligned holes in the noise protection device 30 from top to bottom. They bring about stability of the noise protection device composed of the individual elements 1, both during transport and during assembly, and also after Install.
  • the space 32 remaining between the metal rod 31 and the perforated wall 11 can be filled with a casting compound, for example made of mortar or plastic.
  • the noise protection device 30 is within a noise protection wall 46, i.e. in the assembled state. It is held on both sides by vertical iron supports 34, 36 anchored in a concrete base 33 and having an I-shaped cross section (FIGS. 2 and 9). The anchoring and load transfer can also be done using so-called U or double T-bars.
  • the iron supports or supports 34, 36 can be preassembled with the noise protection device 30. They have a profile 4 ', 5' corresponding to the noise protection elements.
  • the noise protection device 30 (in FIGS. 5 and 6) rests with its underside 38 on a base 40. The latter can be made of earth or made of concrete.
  • the top 42 of the noise protection device 30 carries a longitudinal beam 44 made of concrete, which acts as a load distribution element.
  • a load distribution element can also be arranged on the underside of the noise barrier.
  • the sectional noise protection wall 47 has noise protection elements 1 'with ribs 4, 5 on both sides.
  • a longitudinal bar 44 rests on the uppermost noise protection element and bears a roof 48 on both sides, which extends far beyond the noise protection wall 47.
  • the latter is fastened to the longitudinal bar 44 by means of two hinges 50, 52 and, if necessary, can be attached to one or other side can be folded down. Rising sound is contained by the canopy 48, which means that lower noise barriers can be used.
  • Noise protection walls of this type which are effective on both sides can be erected between roadways and rails. As a result of the irregular loading on both sides, particularly high demands are placed on its stability.
  • the bilaterally active, i.e. Sound-absorbing noise barrier 47 in Figures 12 and 13 is provided with a roof structure.
  • the noise protection wall 47 is provided with a slightly curved canopy 54 which projects far on one side in the direction of the greater noise exposure (front side) and is arranged pivotably about a hinge 56.
  • the hinge 56 is arranged on a longitudinal bar 44 which sits on the noise barrier.
  • the position 54 'assumed after pivoting the canopy is shown by dash-dotted lines.
  • the mutually equally high ribs 4 'having noise barrier 48 has at its upper end a longitudinal beam 60 which carries a canopy 66 which extends far over both sides over the noise barrier 48.
  • the canopy 66 can be pivoted by means of hinges 62, 64 on both sides of the noise protection wall 48 in an approximately parallel position to the latter.
  • the canopy 66 in these two positions 66 ', 66 ⁇ is shown by dash-dotted lines.
  • the surface facing the noise which is also referred to as the sound absorption surface, can have any other suitable profiling in addition to the rib shape shown. Such forms are known. Elements with different sound absorption areas can also be assembled within a noise protection device.
  • the sound absorption walls can be adapted to the respective, in particular the noise requirements.
  • the noise barrier has only one active area or sound absorption area, the other area can take on another function, e.g. as a plant base, or have an aesthetically pleasing design.
