Description

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.

In order to dampen noise emanating from a linear or areal noise source (eg roads, railways, factories), 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. Depending on the prevailing environmental and noise conditions, many different noise barriers are in use, which are adapted to the specific situation or should be adapted.

For noise barriers, 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. Mostly fine-fiber, foam-like and haufwerkporige 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.

Noise barriers used to delineate railway lines, particularly high speed lines, must also have high dynamic stability to withstand the air blasts generated by passing trains. In high-speed trains, some of which run at over 300 km / h, this load is considerable, in particular, since the noise barriers can be built very close to the train lines. The walls must be able to be dismantled quickly in the event of a disaster, which is a problem, especially in massive noise protection buildings made of concrete. Noise barriers made of riveted and bolted sheets have the disadvantage of low fatigue strength.

The FR 2267603 A discloses a sound-absorbing 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 each other 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. Disassembly is also very expensive, because many individual screws must be solved. Also, it is not intended to use the profiling of the vertical struts simultaneously as holding elements for the wall modules.

From the CA 2 393 384 A1 a soundproof wall has become known, which uses long, partly internally stiffened and glued hollow panels preferably made of plastic extruded or fiberglass, which are stacked between supports to a wall, then to be filled with a sound-insulating liquid, sand or earth, etc. , Between the hollow panels horizontal profiles 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. However, the rubber elements cause no stabilization or clamping action the vertical support. Fixing of panels in accordance with CA 2 393 384 done 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.

This is achieved in that according to the invention in each case between two adjoining wall modules on its longitudinal side in the profile of the struts deformable squeeze pads are arranged, which are supported and clamped under the pressure of the wall modules on the profile of the struts. This ensures a rich hold of the slide rail in the struts. The Quetschpölster are elastic and give load-related twists of the one-sided open profile of the slide rails enough leeway.

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 pass. Furthermore, the squeeze pads allow a heat-related longitudinal expansion of the insertion profiles.

It is important that unlike closed assembled profiles, so-called cassettes (screws, rivets or the like connected shells), an open profile is used in which the insulating material is thus exposed. This causes that caused by the staggered deflection of the struts under the compressive stress of the medium by the train passing between train and soundproof wall and the subsequent spring back of the struts stress each located between two consecutive struts Sections of the soundproof wall on twisting (torsion) in one-sided execution of the profiles caused no stress on any fasteners. In contrast, the fastening elements between the screws are subjected to shearing in double-shell design, the fractures of these fasteners, or the lining of the rivet holes causes a rupture of the clam shell closed profiles.

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. It can be built with a limited set of components a variety of different noise protection structures that can be adapted to the prevailing conditions and requirements.

In a preferred embodiment of the invention, the struts are arranged substantially vertically, the wall modules lie with their longitudinal edges to each other and the Quetschpolster are burdened by the weight of the overlying wall modules. The use of squeeze pads allows a particularly simple, yet stable installation of a noise barrier. This type of holder also allows rapid and non-destructive disassembly in case of disaster, repair or replacement, without special tools.

In an advantageous manner, in each case two wall modules bordering on their longitudinal side can be connected to one another on the longitudinal sides of the mutually adjacent insertion rails by means of snap connections. The snap connections secure the slide rails against each other and prevent clashing and rattling, such as due to a puff of air due to a passing train.

In a further embodiment of the invention, the struts are formed as substantially vertical I-beams, wherein they are preferably supported in the lower region of a strut foundation, from which they protrude. Single or more of the struts can also be designed in several parts, wherein preferably the strut has a rear T-bar and at least one detachable on the T-bar, preferably fastened by screws jaw, which can exert a preferably adjustable pressure on the Quetschpolster. In the lower part of the structure, a concrete base or a skirt, preferably made of metal, may be arranged. By such a structure noise walls of different heights can be built in a row, wherein the clamping of the crimp pads by means of jaws, especially for lower sections, or in the uppermost wall area may be appropriate, if there is not sufficient to the self-weight of the overlying wall elements for clamping deformation of Quetschpolster.

In a preferred embodiment, the insertion rail has a hollow profile which is open toward one side or towards two sides, wherein preferably one or more guide springs or guide strips engaging in a groove of the absorber elements are provided on the profile, and preferably at the upper and lower sides Outer sides of the profile of the insertion rail projecting, designed as a snap connection spring elements for connection to the longitudinally adjacent insertion rail are provided. Furthermore, 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. In the end region of the insertion rail may be provided 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. In this case, at least one surface of the web of the Quetschpolsters have a wavy surface, which is in contact with the insertion rail. Furthermore, the crimp pad can have at least one slip-on groove on at least one side. As a result, 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 Crushed squashed transversely to the printing 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 insertion rail.

In a further embodiment, the absorber elements have an absorber inner part and at least one absorber outer part, wherein the absorber inner part is arranged in the interior of the insertion rail, and the absorber outer part of the Slide rail protrudes outward. Between the absorber inner part and the absorber outer part, at least one insertion groove is preferably provided, wherein guide grooves can be provided in the absorber inner part. As a result, the absorber elements can be pushed onto the insertion rail in a form-fitting manner with the absorber inner part along the insertion groove. Alternatively, the absorber element can also be inserted from the front transversely into the insertion rail and the insertion grooves of the absorber element can then be brought into engagement with the guide springs of the insertion rail by rotating the absorber element. Here, the absorber outer part protrudes from the slide rail and determines, together with the adjacent absorber outer parts on the same, as well as with the absorber outer parts on the adjacent slide rails, the surface contour of the wall. The inserted absorber can be designed so that they largely turn off the reflection of the incident sound energy to completely, in particular by the fact that the absorber cover all hard parts of the rails.

Advantageously, the profile of the absorber outer parts in a plane transverse to the insertion rail is rectangular, curved, semicircular, circular segment, triangular or sawtooth, and the cross section of the absorber outer parts in a horizontal plane along the insertion rail is preferably rectangular or chamfered on one or two sides , wherein a combination of a plurality of differently shaped absorber outer parts may be provided on a slide rail. Absorber elements can also be formed as a toothed plate, wherein a plurality of spaced-apart absorber outer parts are interconnected by a single, elongated absorber inner part. Absorber elements can also be designed as a preferably elongated absorber inner part (flat plate) which is arranged completely inside the insertion rail. By using such components, a noise barrier can be provided with almost any surface that can be adapted to the corresponding noise conditions. By using various absorber elements in a wall area, surfaces with a regular or irregular structure can be formed.

In a preferred embodiment, the structure is designed as a highly absorbent noise protection wall, preferably for noise reduction of rail lines for high-speed trains. Such a noise barrier has the advantage that the stable construction of the wall provides a high fatigue strength, while the Absorber elements can be relatively easily replaced and replaced as wearing parts as needed.

Fig. 1 shows a portion of a noise barrier constructed in accordance with the present invention. When setting up the noise barrier 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-profile 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. Because of the simplicity, 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. Directly above the foundation, as the first wall module, a base element 17, such as a prefabricated concrete element or a skirt of metal, inserted, which forms a conclusion to the ground. Above 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 exact structure of these wall modules will be described in more detail in connection with the following figures. In the illustrated wall, 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. On the open side of each I-strut, 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.

Fig. 4 shows a part of the wall elements, which correspond to those of Fig. 1 for the sake of clarity, the I-strut is not shown. 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.

On the upper surface of the insertion rail 1 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. Alternatively, the clamping force may be applied by means of clamping elements, an example of which will be described below with reference to FIG Fig. 6 described in more detail. Through the use of such Quetschpolster 4 can be omitted in an optimal case to an additional attachment of the wall modules 7, such as by means of screw, rivet or welded joints, as well as on other covers, which greatly facilitates the assembly, and also allows rapid degradation, as in In the course of a deployment as a result of a train disaster, which must be created quickly greater access to the accident site, or for maintenance / repair work. The system can therefore be dismantled easily and non-destructively, and an exchange and a Renewal of the absorber elements is easy to perform. Replaced or dismantled components can be sorted sorted and disposed of or recycled.

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 the Slide rail 1 are attached. For this purpose, 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.

To illustrate the versatility of the invention are to the individual, in Fig. 2 shown, insertion rails pushed various absorber elements, by the combination of different combinations depending on the needs can be created to provide optimal noise absorption according to a certain noise spectrum. The topmost insertion 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 elongate 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 forms 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.

In the second slide rail of the Fig. 2 are each two absorber elements with one side bevelled absorber outer parts assembled so that there is a double wedge-shaped structure, in the third insertion rail a variety of absorber elements 2 are arranged side by side, forming a highly structured surface.

Fig. 3 shows an overview of in Fig. 2 used absorber elements as an example of versatility and thus design freedom of the absorber. The absorbers shown each have an absorber outer part 13 and an absorber inner part 12. At the transition between the absorber outer part 13 and the 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 of the adjacent slide rail educated. In this case, 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. Since 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. Alternatively, it is entirely possible to dispense with elastic clamping, in which case the spring elements only prevent lateral displacement of the insertion elements and the insertion elements engage in one another in a form-fitting manner.

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. In Fig. 6 the jaw is designed as a T-profile, or as two L-angle, which are fastened with the clamping screws 18 to the rear T-profile of the strut. In this case, 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. At the top, 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 Schnappfedem so that they can be mounted in the same manner as the stacked profiles with each other with a snap connection 9 on the profile of the top rail.

In Fig. 7 different arrangements of absorber elements 2 are compared in a horizontal cross-sectional view. 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 in the I-profile of the struts 3 reaching ends of the slide rails 1 are shown in more detail. In order to allow a length compensation of the insertion rails (for example due to weathering), 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 cutting plane (this is the one in Fig. 10 Sectional plane VIII - VIII) 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, is therefore in Fig. 8 to see.

The width of the insertion rail 1 is a little narrower than the inner distance between the outer walls of the I-profile of the strut 3, so that the ends of the crimp pad 4 are clamped therebetween. Fig. 10 is a sectional view along the section line X - X in Fig. 8 , wherein the position of the arranged between the slide rails 1 Quetschpolster 4 is illustrated. In comparison with the Fig. 9 which is a sectional view along the section line IX - IX in Fig. 8 is, it can be seen that the protruding from the insertion rail outward spring elements of the snap connection 9 ( Fig. 9 ) are located in the area of the crush pads ( Fig. 10 ) to create 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 working principle of the corrugated surface for the reinforcement of the clamping effect will be described below with reference to FIG Fig. 12 explained.

The Fig. 9a and 10a show a further embodiment of the invention, wherein the insertion rail is designed as open on two sides hollow profile. The profiles shown are similar to those in FIGS. 9 and 10 shown, on the back, however, are also provided at the top and bottom two formed as an L-profile ribs 1 ', so that the hollow profile provides on both sides of an insertion possibility for absorber elements. The middle wall of the two-sided hollow profile corresponds to the rear wall of the in the FIGS. 9 and 10 represented profile. 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. By a suitable choice of the hollow profile, such as with a straight center wall and a symmetrical insertion profile, 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.

As struts 3, the same I-profiles can be used as in the FIGS. 9 and 10 wall shown, wherein the additional L-profiles of the hollow profile in the end should be removed before assembly (such as sawing or milling), so that the end portions fit into the I-profile of the struts 3. Alternatively, wider struts could be used in which the entire width of the double-sided hollow profile fits. In this case, other crimp pads would have to be used for the new profile width.

Fig. 11 another embodiment shows a squeeze pad suitable for use with those described above with reference to FIG Fig. 2 described insertion rails with "roof-shaped" spline is provided. In this case, no cutting of the profile is required to aufzustecken the Quetschpolster, but it can be dented or milled the support surface, so that a recessed support for the Quetschpolster is achieved. In order to achieve a lateral clamping effect with this squeeze pad, it is necessary that the kink in the web of Quetschpolsters has a more acute angle, as the "roof angle" of the insertion rail. Fig. 12 clarifies this mode of action.

Fig. 12 schematically shows how the compression of a crimping pad 4 between two insertion rails 1 leads to a broadening of the central web of the Quetschpolsters 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. When the space is limited to the side, such as through the wall of the I-profile of the strut 3, 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.

In Fig. 13 Several types of crush pads are juxtaposed. The crushing pad designated b) is corrugated only at the top of the central web, and formed flat at the bottom. The functionality is analogous to that in relation to Fig. 12 described. 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.

The invention can not be used only for straight, vertical walls. Rather, kinks or bends of the wall can be provided, as in Fig. 15 is shown. Fig. 15 shows differently shaped walls in cross section. In this case, the strut 3 can be arranged at different angles to give a sloping wall as in a). The strut designated b) is provided with a kink, resulting in a cranked wall, in c) is again shown an inclined wall having a kink at ground level, whereby the strut 3 can be anchored just in the foundation, and d) shows an arcuately curved wall.

Fig. 16 shows by way of example a selection of different types of foundation for the struts 3, wherein the invention is not limited to the use of a foundation. a) shows a pile foundation, in b) a slab foundation with ductile piles is anchored in the ground, and c) shows a strip foundation. In c) the struts 3 are fixed without foundation on concrete blocks (delta block).
