Definitions
- the invention relates to a structure, preferably for sound-insulating boundary of traffic routes, which permanently mounted, provided with a profile struts and a plurality of elongated wall modules, which are each arranged between two struts and are held by the profile of the struts, wherein a plurality of wall modules, the their longitudinal sides adjoin one another, form a substantially closed wall, wherein at least one of the wall modules at least one insertion rail, which is in particular designed as a profile rail, on which a plurality of absorber elements on or are pushed.
- noise protection walls and noise barriers are used so that at an immission location to be protected (eg residential buildings, hospitals) Noise is attenuated to the extent that the legal limits are complied with.
- noise barriers are in use, which are adapted to the specific situation or should be adapted.
- the achievable noise reduction depends mainly on the height of the noise barrier, the distance from the noise source, the distance from the immission, the height of the immission, the frequency spectrum of sound, as well as the acoustic design of the noise barrier. Furthermore, reflection on obstacles, ground reflection and sound diffraction play an important role. When selecting suitable noise barriers, the frequency and intensity of the noise pollution should also be taken into account. Also, the prevailing weather conditions must be considered, especially with regard to the building material.
- the achievable effect of a soundproofing construction also depends substantially on the nature of its surfaces, often noise-absorbing materials are used, which usually have a porous or fibrous microstructure.
- An uneven structure such as by a plurality of protruding blocks and recesses arranged therebetween enhances the absorption effect of the materials.
- fine-fiber, foam-like and hauftechnikporige absorber are used.
- Most absorber materials can not be used for structural components because they are not designed for such mechanical loads. Since many absorber materials wear out over time, care must be taken that they do not remain uncontrolled inside noise barriers and crumble or rot there.
- FR 2267603 A discloses a sound-insulating structure containing profiled vertical struts, wherein in each case at the front of such struts profiles are fixed with wall modules, so that the wall modules adjoin one another at their longitudinal sides and form a closed wall.
- the wall modules are each pushed onto profiles, which are fastened by screws to the strut.
- the modules are screwed to the struts from the outside, whereby the screws can relax under a dynamic load, such as occurs in passing trains. Due to the torsion-resistant elements, the screws are stressed dynamically under load-induced twisting. The twisting of the profiles within the wall is caused by the staggered deflection of the struts due to the impact load of the pulling pass.
- a soundproof wall which uses long, partly internally stiffened and bonded hollow panels preferably made of plastic extruded or fiberglass, which are stacked between supports to a wall, then with a sound-insulating liquid, with sand or Earth, etc. to be filled. Between the hollow panels Horizontalproflle are arranged, which serve to stabilize the panels. Between the horizontal profiles and the hollow panels rubber elements are inserted along the entire length of the hollow panels. The rubber elements serve a positive fit between horizontal profiles and hollow panels.
- the rubber elements cause no stabilization or clamping effect the vertical beams.
- the fixation of the panels according to CA 2 393 384 is carried out with screws without acoustic, electrochemical insulation.
- the decisive factor is the lack of an elastic shape, so that the load-related twisting of the panels, which is caused by the time-displaced by the passing trains, staggered deflection of the vertical support, elastic is not given space, because the panels are practically clamped.
- the aim of the invention is to provide noise barriers, which meet the above requirements, are relatively inexpensive and are flexibly tuned to a variety of noise and environmental situations, the components used can be standardized to a high degree.
- the absorber elements are easily replaceable.
- the slide rails are decoupled with respect to the structure-borne noise vibration technology of the struts.
- the Quetschpolster also represent an electrochemical separation.
- the invention makes use of one- or two-sided open slide rails, which are elastically held in the struts by means of Quetschpölster and thus provide the load-related twists scope and thus fatigue.
- the elastic storage means of Quetschpölstern thus dampens the load-related twisting of the profiles within the wall, the twist caused by the staggered deflection of the struts due to the impact load in the train passing.
- the squeeze pads allow a heat-related longitudinal expansion of the insertion profiles.
- Sections of the soundproof wall on twisting (torsion) in one-sided execution of the profiles caused no stress on any fasteners.
- the fastening elements between the screws are subjected to shearing in two-shell execution, the fractures of these fasteners, or the lining of the rivet holes causes a rupture of the clam shell closed profiles.
- noise barrier As elements of the noise barrier according to the invention simple components, such as rails, which provide the required stability, are provided with noise-absorbing materials that provide a high level of noise protection.

- a closing element can be provided on the last insertion rail of the wall, which is preferably connected by means of a snap connection with the last insertion rail.
- a recess which is preferably formed as a cutout or indentation and in which a squeeze pad is inserted.
- the use of an open hollow profile for the insertion rail, on which the longitudinal snap connection and guide elements for inserting the absorber elements are provided, allows easy production of the insertion rail, such as extruded aluminum profile, which cut to size and edited in the end for receiving the crimping becomes.
- the squish pad may advantageously have a substantially I-shaped profile, wherein in the web of the I-profile in the middle a kink can be provided.
- at least one surface of the web of the Quetschpolsters have a wavy surface, which is in contact with the insertion rail.
- the crimp pad can have at least one slip-on groove on at least one side.
- the crimp pad can be well adapted to the profile of the insertion rail, wherein a corrugation on a contact surface causes a crushed between two insertion rails crimp squashed transverse to the compression direction apart, so the web of Quetschpolsters is extended, whereby the Quetschpolster on both sides presses against the profile of the strut, and jammed with this. If the slide rail in the edge region upwards or downwards open (for example, by a cutout), so the Quetschpolster can be plugged by Aufstecknuten on the slide rail.

- vertical I-struts (posts) 3 are anchored at regular intervals by means of a foundation 6 in the ground or on a solid base, so that the I-Prof ⁇ l is aligned with an open side to the next strut 3 out.
- the foundation embedded in the ground is only one example of many ways of securing the strut, but the invention is not limited to attachment to a foundation or even to a foundation shape. It is essential only that the struts are kept sufficiently stable. Between two struts individual wall modules 7 can now be inserted from above and stacked one above the other to form a wall.
- the I-profile represents a particularly preferred embodiment of the struts 3, however, any profile that allows insertion of the wall modules can be used.
- the length of the wall modules 7 is adapted to the distance between the middle walls of the second I-struts, the width is matched to the inner spacing of the side walls of the I-beam, so that the wall modules are held between the I-struts.
- the base element a plurality of wall modules are arranged, which according to the invention are designed as slide-in rails 1 with absorber elements 2 pushed onto them, whereby a structured surface is formed in order to achieve a high sound absorption.
- the absorber elements form a plurality of rows of forwardly projecting cuboids or wedges, one row each being disposed on a single slide rail.
- the absorber elements can be formed as plates, wedges, cuboids or free shapes.
- the next section of the noise barrier can now be added to another strut, creating a continuous noise protection wall of any length can be built.
- the slide rail 1 has a forward open profile, wherein in the profile and at its opening a plurality of guide springs 10 extend, which engage in corresponding guide grooves 15 of the absorber elements 2, wherein the individual absorber elements 2 are inserted from the side into the hollow profile, so a part of the absorber element protrudes through the opening of the hollow profile to the outside.
- the slide rails may be formed as profile rails, which may be made for example by means of an extrusion process.
- spring elements are provided on the outside, which form a snap connection 9 with corresponding spring elements on the lower surface of the overlying insertion rail 1, which will be explained in more detail below.
- the spring elements of the snap connection 9 are in the end region of the profile, such as by cutting away, deforming or milling away, 20, whereby opposite flat surfaces are formed, which serve as a support 8 for a squish 4, 21.
- the squish pads are preferably made of a compressible, Preferably, elastic material and serve on the one hand the damping of vibrations, on the other hand, the crush pads are deformed by the pressure acting on them of the slide rails 1 so that they expand to both sides, causing them with their ends from the inside against the outer walls of the I-profile push the struts 3 and achieve a clamping effect.
- the Quetschpolster also provide a non-contact mounting of the slide rails in relation to the struts, whereby they are decoupled from these vibrationally and electrochemically.
- the required pressure force on the crush pads is preferably exercised by the weight of the overlying slide rails 1.
- the clamping force can be applied by means of clamping elements, an example of which will be described in more detail below with reference to FIG.
- Fig. 2 shows a further embodiment of the invention.
- the slide rail 1 is wedge-shaped on the upper and lower surfaces, whereby adjacent slide rails are positively superimposed, was dispensed with a snap connection.
- This profile can be produced in a particularly simple manner, for example as a folded sheet metal or using deformed composite sheets.
- the Quetschpolster have substantially an I-profile, wherein the middle wall is reinforced to one side to the edge of the profile, whereby on one side of the profile (on the underside of the squish pad) two Aufstecknuten 11 are formed, which on the end of Slide rail 1 are attached.
- the roof-shaped wall is cut away at the top in the end region of the insertion rail, so that two upwardly open wall parts remain, on which the Aufstecknuten 11 of the Quetschpolsters 4 fit.
- various absorber elements are pushed onto the individual slide rails shown in FIG. 2, the combination of which can be used to create a wide variety of surface shapes in order to provide optimal noise absorption in accordance with a specific noise spectrum.
- the uppermost slide rail is provided for example with a plate-shaped absorber element which has no outwardly projecting absorber outer part 13, but only consists of an elongated absorber inner part 12. Due to the greater length of the element fewer absorber elements are necessary to fill a slide rail 1 over its entire length. Also, this shape is easier to produce us cheaper than more complex shapes with an absorber outer part. However, due to the resulting less textured surface of the wall, the sound absorbing effect of such elements is less.
- FIG. 3 shows an overview of the absorber elements used in FIG. 2 as an example of the versatility and thus design freedom of the absorbers.
- the absorbers shown each have an absorber outer part 13 and an absorber inner part 12.
- guide grooves 15 are provided at the top and bottom, which are pushed onto the corresponding guide springs 10 of the insertion profiles.
- Fig. 5 shows a cross section through a slide rail 1, on which an absorber element 2 is pushed, as well as the connection to the adjacent slide rails by means of a snap connection 9.
- the snap connection 9 is characterized by two spring elements on the top of a slide rail and two spring elements on the underside formed of the adjacent insertion rail.
- a bead is provided at the end of the spring elements on the upper side, which engages in a notch in addition to the spring elements of the underside of the adjacent insertion rail.
- the spring elements on the underside serve on the one hand to position the slide rails when stacking, on the other hand, they are slightly pushed by the bead of the opposite spring elements to the side, whereby they exert an elastic clamping force on the bead.
- the elements are mainly intended to secure against lateral displacement (for example, in the case of a counteracting oscillation of the long insertion elements), however, generally only a small clamping force of the snap connection is required since the insertion elements 1 are pressed against one another by their own weight.
- Fig. 6 shows a soundproof wall in exploded view, wherein one of the struts is formed in several parts.
- the strut 3 has only below, in the region of the base member 17, an I-profile, above it is only the rear outer wall of the I-profile upwards, which supported to the rear, in the form of a T-profile, by an additional support strut is.
- the arranged between the slide rails Quetschpolster are not clamped due to the deformation under pressure from the inside against the walls of a fixed profile, but compressed between the T-strut and one or more jaws by means of clamping screws 18 from the outside.
- Fig. 6 shows a soundproof wall in exploded view, wherein one of the struts is formed in several parts.
- the strut 3 has only below, in the region of the base member 17, an I-profile, above it is only the rear outer wall of the I-profile upwards, which supported to the rear, in the form of a T-profile, by an additional support strut is
- the jaw as T-Prof ⁇ l, or formed as two L-angle, which are fastened with the clamping screws 18 to the rear T-profile of the strut.
- the T-profile of the jaw is so short that it does not touch the rear T-profile, so that the entire clamping force is transmitted through the Quetschpolster.
- the lowermost squeeze pad which separates the lowermost insertion rail from the base element 17, lies on the flat surface of the Base element.
- the wall may be delimited by an end element 5, for example in the form of a bevel edge cover.
- the cover is also provided with snap springs, so that they can be attached to each other in the same way as the stacked profiles with a snap connection 9 on the profile of the top rail.
- the absorber element denoted by b) differs from all others in that four absorber outer parts form an absorber element 2 on only one absorber inner part 12. Although this form has a higher complexity, due to the smaller number of absorber elements, however, the sliding of the elements is simplified on the insertion rail. By using different absorber elements, it is not only possible to provide walls with a simple structure, but also complex patterns or reliefs could be formed on a wall.
- Fig. 8 shows a cross section of the wall in a horizontal plane, wherein the in the I-profile of the struts 3 reaching ends of the slide rails 1 are shown in more detail.
- an elastic damping element 19 between the end of the insertion rail 1 and the inner wall of the I-profile of the strut 3 is arranged.
- the sectional plane (this is the sectional plane VIII-VIII shown in FIG. 10) is located in the lowermost region of the insertion rail, approximately at the height where the curved back of the profile has a maximum width.
- the guide spring 10 which engages in a corresponding guide groove 15 of the absorber elements, can therefore be seen in Fig. 8.
- Fig. 10 is a sectional view taken along the section line X - X in Fig. 8, wherein the position of the arranged between the slide rails 1 crimping pad 4 is illustrated.
- FIG. 9 which is a sectional view along the section line IX - IX in FIG. 8, it can be seen that the spring elements of the snap connection 9 (FIG. 9) projecting outward from the insertion rail are removed in the vicinity of the crushing pads ( Figure 10) to provide a flat support for the crush pads.
- the Quetschpolster itself have approximately the shape of a "dog bone” and have on the support surface on a wavy surface, which reinforces the Clamping action is used.
- the operating principle of the corrugated surface for the reinforcement of the clamping effect will be explained below with reference to FIG.
- FIGS. 9a and 10a show a further embodiment of the invention, wherein the insertion rail is designed as open on two sides hollow profile.
- the illustrated profiles are similar to those shown in Fig. 9 and Fig. 10, but on the back are also provided at the top and bottom two formed as an L-profile ribs 1 ', so that the hollow profile provides an insertion possibility for absorber elements on both sides.
- the middle wall of the two-sided hollow profile corresponds to the rear wall of the profile shown in FIGS. 9 and 10.
- the absorber elements 2 'pushed onto the rear side of the hollow profile 1' may be formed similarly to the absorber elements 2 used on the front side.
- the same design absorber elements could be used for both the front, as well as for the back, whereby fewer different components would be required.
- the same I-profiles can be used as in the in Fig. 9 and
- Fig. 11 shows a further embodiment of a crimp pad intended for use with the "roof-shaped" spline insert rails described above with reference to Fig. 2. No cutting of the profile is required to mount the crimp pad, however In order to achieve a lateral clamping action with this crimp pad, it is necessary that the kink in the web of the crimp pad has a more acute angle than the "roof angle" of the insertion rail.
- Fig. 12 illustrates this mode of action.
- FIG. 12 shows schematically how the compression of a crimping pad 4 between two insertion rails 1 leads to a broadening of the center web of the crimping pad 4.
- the individual waves of the bridge are compressed and soft elastic to the side.
- the squeezed crush pad is shown with broken lines.
- Each individual wave of the web causes due to the elasticity of the material when compressed, a slight extension of the bridge, wherein the effected by each wave extension adds up with multiple waves to a total extension.
- the crush pad abuts the wall laterally, thereby exerting a clamping force sideways.
- Fig. 14 shows the inserted between two insertion profiles Quetschpolster showing how the clamping effect of Quetschpolster is reinforced by the shape of the insertion profile by the ends of the Quetschpolsters are compressed wedge-shaped up and down between the insertion profile and the profile of the strut 3.
- the squish pad designated b) is corrugated only at the top of the central web, and formed flat at the bottom. The mode of operation is analogous to that described with reference to FIG. 12. The same effect is achieved by the use of the creased I-profile crimping pad c), the crease of which is compressed from above and below, thereby reducing the kink angle and thus extending the web of the plow to both sides.
- Fig. 15 shows variously shaped walls in cross section.
- the strut 3 can be arranged at different angles to give a sloping wall as in a).
