Description
Self-supporting noise barrier
Field of the invention
The present invention relates to a noise barrier, in particular a self-supporting noise barrier for traffic noise abatement.
Background art
Highways, railway tracks, airports, industrial areas and the like are often a source of high noise levels and as a result noise reduction is often required to allow for acceptable noise levels in residential areas in close proximity to these noise sources. Noise barriers are typically deployed along highways to achieve sufficient traffic noise reduction for residential areas.
US patent application US 2005/0178613 A1 discloses a panel assembly for a traffic noise barrier wall of the type that utilizes spaced apart, vertically mounted posts having arranged there between panels for blocking road noise. Such noise blocking panels can be made of wood or concrete, and wherein the vertical posts may be made of a rigid material such as steel or concrete.
A great variety of noise barriers presently exist that are very similar to the above mentioned noise barrier wherein upright positioned posts are utilized for mounting panels there between and thereon. One common features of prior art noise barriers is that they often require dedicated foundations for mounting a concrete and/or steel structures thereon that supports noise blocking panels. However, such prior art noise barriers are relatively complex to install due to all the ground work that is required and that a dedicated concrete and/or steel structure is needed for supporting panels in some required configuration.
Summary of the invention
The present invention aims to provide a noise barrier, in particular a self-supporting noise barrier for traffic noise abatement, wherein the noise barrier is modular, easy to install and provides excellent structural strength and noise reduction.
According to the present invention, a noise barrier of the type defined in the preamble is provided comprising a rigid first panel having a first connecting edge and a rigid second panel having a second connecting edge, wherein the first and second connecting edges are pivotally connected, e.g. hinged.
The first panel further comprises a first supporting edge opposite the first connecting edge and wherein the second panel comprises a second supporting edge opposite the second connecting edge, the first and second supporting edges are configured to be positioned on the ground for a predetermined pivot angle (a) larger than zero between the first and second panels.
The rigid first and second panels form a pivotable or hinged arrangement of panels for forming an A-shaped or inverted V-shaped noise barrier to be easily positioned on the ground that provide for excellent structural integrity due to the triangular shape. There is no need for a separate steel or concrete structure for supporting panels as the hinged arrangement of the rigid first and second panels already provides for sufficient structural strength.
In an advantageous embodiment, the first and second panel each comprise a cement bonded wood fiber material to optimize noise blocking and noise absorption.
In a further advantageous embodiment, the cement bonded wood fiber material is provided on an outward facing side of the first and second panel, i.e. thus wherein the wood fiber material faces incoming noise.
For further optimised noise reduction, in an embodiment the first and second panel each further comprise concrete, thereby adding more weight that will facilitate reduction of lower frequencies but also to increase structural strength and stability. In a further embodiment the concrete may be provided on an inward facing side of the first and second panel.
In an advantageous embodiment, each of the first and second panels may further comprise one or more internally extending reinforcement beams or ribs to further increase structural stiffness, so that the self-supporting property of the A-shaped noise barrier is even further improved.
According to the present invention, the first and second supporting edges of the first and second panels, respectively, may be placed on the ground or even buried therein. Alternatively, in an advantageous embodiment the noise barrier may further comprise two support beams, e.g. made of concrete, for placement on or partly into the ground. Each support beam may then be provided with a laterally extending first groove at a first end portion of the support beam and a laterally extending second groove at an opposing second end portion of the support beam. The first and second laterally extending grooves are then configured to receive the first and the second supporting edges respective through, e.g., clamping action. Utilizing such support beams with prefabricated lateral grooves further guarantees that when placed therein, the first and second panels are positioned at the required pivot angle.
Short description of drawings
The present invention will be discussed in more detail below, with reference to the attached drawings, in which Figure 1 shows a noise barrier according to an embodiment of the present invention.
Description of embodiments
Figure 1 shows a noise barrier 1 according to an embodiment of the present invention. In the embodiment shown the noise barrier 1 comprises a pivotally or hinged arrangement of a first and second panel 2, 4 for placement on the ground in an A-shape or inverted V-shape configuration to provide a self-supporting structure exhibiting excellent structural integrity. Here, the first and second panel 2, 4 are sufficiently rigid to prevent spontaneous buckling or bending thereof. As shown, the rigid first panel 2 has a first connecting edge 3 and the rigid second panel 4 has a second connecting edge 5. The first and second connecting edges 3, 5 are pivotally connected and as such form a hinged arrangement of panels.
The pivotable connection between the first and second panels 2, 4 allows the panels to pivot toward a required pivot angle (a) between 0 and 180 degrees, so that any required A-shape or inverted V-shape for the noise barrier 1 can be obtained. For example, keeping the pivot angle (a) relatively small (e.g. < 45°) would increases a vertical height H of the noise barrier 1, whereas keeping the pivot angle (a) relatively large (e.g. > 90°) would lower the vertical height H.
The first panel 2 further comprises a first supporting edge 6 opposite the first connecting edge 3 and wherein the second panel 4 comprises a second supporting edge 7 opposite the second connecting edge 5. The first and second supporting edges 6, 7 are configured and adapted to be positioned on the ground such that a predetermined pivot angle (a) larger than zero is provided between the first and second panel 2, 4.
According to the present invention, the rigid first and second panels 2, 4 form a pivotal or hinged arrangement of panels for forming an A-shaped or inverted V-shaped noise barrier to be easily positioned on the ground and provides excellent structural integrity. In the inverted Vshaped position, the first and second connecting edges 3, 5 define the apex of noise barrier 1 whilst the first and second supporting edges 6, 7 define the base of the noise barrier 1.
One of the main advantages of the noise barrier 1 is that a separate steel and/or concrete structure for supporting panels is not needed as the hinged arrangement of the rigid first and second panel 2, 4 already provides for sufficient structural strength and stability by virtue of a triangular shape when the first and second panels 2, 4 are positioned at the required pivot angle (a). Furthermore, the first and second panels 2, 4 can each be configured to meet any noise required reduction by utilizing specific materials, surface textures etc. for achieving required specifications.
In an exemplary embodiment, the first and second panels 2, 4 may each comprise a wood fiber material, e.g. cement bonded wood fiber, which provides excellent sound absorption such that the efficacy of the noise barrier 1 is improved. Moreover, by directing the cement bonded wood fiber material toward a noise source, even further noise reduction can be attained. Forthat purpose an embodiment is conceivable wherein the cement bonded wood fiber material is provided on an outward facing side 8 of the first panel 2 and an outward facing side 9 of the second panel 4, which faces 8, 9 would typically receive incoming noise.
The overall weight of each of the panels 2, 4 also determines noise blocking capability of the noise barrier 1, e.g. blocking lower frequencies, and so in an embodiment the first and second panel 2, 4 may each comprise concrete. Advantageously, in a further embodiment the concrete may even be provided on an inward facing side 10 of the first panel 2 and an inward facing side 11 of the second panel 4, thereby allowing for a combination of cement bonded wood fiber material facing incoming noise and having concrete in the first and second panel 2, 4 which would lower natural frequencies of the first and second panels 2, 4. It is noted that the inward facing sides 10,11 are to be seen as sides that face each other when the noise barrier 1 is in the Ashaped or inverted V-shaped configuration.
The noise barrier 1 of the present invention can be used for both one-sided and two-sided noise reduction applications. That is, for one-sided applications only the first or second panel 2,4 may face substantial noise sources, such as when the noise barrier 1 is positioned along a single road or railway track. In alternative one-sided applications and embodiments, it would also be possible to use a panel 2, 4 separately as a tunnel wall cladding element for traffic noise reduction in a tunnel. In such applications a panel 2, 4 may then be provided with a relatively smooth inward facing side 10, 11 to be positioned against a tunnel wall and wherein an outward facing side 8, 9 faces noise sources such as traffic for example. Of course, it would also be possible that a panel 2, 4 is provided with a relatively smooth outward facing side 8, 9 to be positioned against a tunnel wall and wherein an inward facing side 10,11 faces noise sources such as traffic. In either case, each of the panels 2, 4 can be adapted to optimally perform as a tunnel wall cladding element to reduce traffic noise.
In two-sided applications both panels 2, 4 face substantial noise sources, wherein an Ashaped or inverted V-shaped noise barrier 1 provides substantial symmetry of the noise barrier 1 as it is positioned on the ground. By choosing suitable panel materials such as the aforementioned cement bonded wood fiber, with or without added concrete, both panels 2, 4 can be tailored to reduce particular noise characteristics. It is even conceivable that the first and second panel 2, 4 utilize different materials and combinations thereof as noise sources on opposite sides of the noise barrier 1 may differ. To further improve structural rigidity of the selfsupporting noise barrier 1, the first and second panel 2, 4 may each comprise one or more internally extending reinforcement beams or ribs (not shown). This embodiment provides an internal reinforcement structure increasing the rigidity and stiffness of each of the panels 2, 4, and due to the internal position of the reinforcement beams/ribs, each of the panels 2, 4 exhibit a thin form factor. Moreover, the internally extending reinforcement beams/ribs further obviate the need for an external support structure to support the first and second panels 2, 4.
In an embodiment the one or more internally extending reinforcement beams or ribs may extend in various directions, e.g. laterally, longitudinally or in both direction of the panels 2, 4 when needed. In an embodiment, the one or more reinforcement beams may even be embedded in concrete for maximum strength of the panels 2, 4. In a further embodiment the internally extending one or more reinforcement beams or ribs of each of the panels 2, 4 may be made of concrete and each of the inward facing sides 10, 11 of the two panels 2, 4 may also be made of concrete in unified fashion with the one or more reinforcement beams or ribs, thereby obtaining inward facing sides 10, 11 and internally extending one or more reinforcement beams or ribs for each panel 2, 4 that are integrally formed of concrete, i.e. as a single piece component. Such an embodiment increases the structural integrity/strength of the two panels 2, 4 even further.
As noted earlier, the noise barrier 1 provides a pivotable or hinged arrangement of two rigid panels 2, 4 for placement on the ground in an A-shape or inverted V-shape. To facilitate positioning and deployment of the noise barrier 1, an embodiment is provided wherein the noise barrier 1 further comprises a lifting member 12, e.g. a lifting lug, arranged along the first and second connecting sides 3, 5 for connection to a lifting device. This lifting member can be used to lift the noise barrier 1 toward a desired location and to facilitate rotation of the first and second panels 2,4 toward the required pivot angle (a).
Depending on the application, the noise barrier 1 of the present invention may be placed in an A-shape or inverted V-shape by positioning the first and second supporting edges 6, 7 on the ground. Should the first and second panels 2, 4 have sufficient weight, then such simple placement of the noise barrier 1 may be ideal for temporary noise reduction, e.g. during road construction. When the noise barrier 1 is to be placed more permanently, it would be possible to simply bury the first and second supporting edges 6, 7 into the ground and, optionally, to embed the supporting edged 6, 7 in mortar, concrete and the like.
In an alternative embodiment, the noise barrier 1 may further comprise two support beams 13 for placement on or into the ground, wherein each support beam 13 is provided with a laterally extending first groove 15 at a first end portion 13a of the support beam 13 and a laterally extending second groove 16 at an opposing second end portion 13b of the support beam 13, wherein the first and second laterally extending grooves 15, 16 are configured to receive the first and the second supporting edges 6, 7, respectively.
In this embodiment the first and second supporting edges 6, 7 are received in the first and second grooves 15, 16 respectively, so that positional stability is provided. Furthermore, a longitudinal distance between the first and second grooves 15, 16 can be chosen to guarantee the required pivot angle (a) when the first and second supporting edges 6, 7 are correctly received within the grooves 15, 16. In an exemplary embodiment, the two support beams 13 may be made of concrete or any other suitable material. Also, the two support beams 13 may simply be positioned on the ground or partly buried therein depending on requirements.
In an advantageous embodiment, the first and second laterally extending grooves 15, 16 may clamp the first and second supporting edges 6, 7, respectively. So the first and second grooves 15, 16 may be in clamping engagement with the first and second supporting edges 6, 7, thereby fixing the first and second panels 2, 4 to the two support beams 13. Optionally, mortar or concrete may be provided in the first and second grooves 15, 16 affixing the first and second supporting edges 6, 7 therein.
As shown in Figure 1, in an embodiment the two support beams 13 are laterally spaced apart along a (lateral) distance substantially equal to a width W of the first and the second panels 2, 4, which would provide maximized lateral or sideways stability.
According to the present invention, the noise barrier 1 may be used for various noise abatement applications, such as the reduction of traffic noise along highways and railway tracks. Since the noise barrier 1 would then be placed next to a highway or railway track, the noise barrier 1 could potentially block an escape route away from the highway or railway track. To allow for such an escape route, an embodiment is provided wherein the first and the second panel 2, 4 each comprise an emergency exit opening 17.
As depicted in Figure 1, to facilitate building a noise wall comprising a plurality of consecutively arranged noise barriers 1, T, 1”, an embodiment is provided wherein the first panel 2 comprises two opposing profiled edges 18 extending between the first connecting edge 3 and the first supporting edge 6, and wherein the second panel 4 comprises two opposing profiled edges 19 extending between the second connecting edge 5 and the second supporting edge 7.
Such profiled edges 18, 19 may then be configured to cooperate with adjoining profiled edges of further noise barriers T, 1”.
In particular, in an embodiment one profiled edge of the two profiled edges 18 of the first panel 2 may be shaped in concave fashion whilst the other profiled edge of the two profiled edges 18 may be shaped in convex fashion. Such a convex-concave pair of opposing profiled edges 18 would allow for seamless connection between the first panel 2 of the noise barrier 1 and a further first panel 2’ of an adjoining further noise barrier 1’. Therefore, the two opposing profiled edges 18 of the first panel 2 may form a concave-convex pair of profiled edges 18 and wherein the two opposing profiled edges 19 of the second panel 4 may also form a concave-convex pair of profiled edges 19. This in turn would allow a noise wall to be built with any desired number of noise barriers 1 which are seamlessly connected, improving noise reduction by minimizing noise leaks between the various noise barriers.
It is noted that in an embodiment the two opposing profiled edges 18 of the first panel 2 and the two opposing profiled edges 19 of the second panel 4 may in fact be flat, e.g. having a flat profile or flat surface profile. This embodiment will still allow for a noise wall to be built with any desired number of noise barriers 1 that are seamlessly connected, but it would require a somewhat higher positioning accuracy when placing each of the noise barriers 1, 1’, 1” to avoid seams there between’. On the other hand, having flat profiled edges 18, 19 would simplify manufacturing of the noise barrier 1.
As mentioned earlier, to facilitate positioning and deployment of the noise barrier 1, an embodiment is provided wherein the noise barrier 1 further comprises a lifting member 12, e.g. one or more lifting lugs, arranged along the first and second connecting sides 3, 5 for connection to a lifting device. In advantageous embodiment it is conceivable that at least one of the two opposing profiled edges 18 of the first panel 2, or one of the two opposing profiled edges 19 of the second panel 4, is provided with a further lifting member for connection to a lifting device. In an embodiment, the further lifting member may comprise two or more spaced apart lifting lugs. Having a further lifting member, e.g. two or more spaced apart lifting lugs, arranged along one of the opposing edges 18 of the first panel 2 or along one of the opposing edges 19 of the second panel 4, allows the noise barrier 1 to be positioned on profiled edges 18, 19 of the first and second panels 2, 4 that are opposite to the further lifting member, e.g. two or more lifting lug. By positioning the noise barrier 1 on one of its profiled edges 18, 19 may be advantageous for storage and transportation purposes to reduce the height of the stored or transported noise barrier
1, e.g. when the height H of the noise barrier 1 exceeds the width W thereof, i.e. of the two panels
2, 4.
Coming back to the pivotable or hinged connection between the first and second connecting edges 3, 5, it may be advantageous to reinforce such a hinged connection between the two panels 2, 4 to increase structural integrity and strength. For example, in the A-shaped or inverted V-shaped position, the apex of the noise barrier 1 comprising the first and second connecting edges 3, 5 may be subject to large forces as it maintains the first and second panels 2, 4 together. To prevent any damage to the hinged connection, an embodiment is provided wherein the noise barrier 1 further comprises a reinforcement housing (not shown) for each of the first and second connecting edges 3, 5. These reinforcement housings for each of the first and second connecting edges 3, 5 provides additional strength to minimize deformation, flexing etc. of the first and second panels 2, 4 along the first and second connecting edges 3, 5. This in turn increases the strength of pivotable or hinged connection between the first and second connecting edges 3, 5 as they are able to withstand higher loads.
Since the two panels 2, 4 are positioned at a predetermined pivot angle (a) with respect to each other, a groove or gap 20 may be formed between the first and second connecting edges 3,
5. However, such a groove or gap 20 at the apex of the noise barrier 1 may collect snow, dirt, leaves and the like. Furthermore, such a gap or groove 20 may not provide desired drainage of rain for example. In order to avoid such problems an embodiment is provided wherein the noise barrier 1 further comprises a cover or cap member arranged over the first and second connecting edges 3, 5, i.e. over the groove of gap 20, to prevent the collection of snow, dirt, leaves etc. and to improve water drainage. The cover member will also improve the aesthetics of the noise barrier
1. In an embodiment, the cover member may be made of any suitable material such as concrete and/or steel, both of which increase the structural integrity and strength of the noise barrier 1.
As shown in Figure 1, the first and the second panel 2, 4 each have a width W between 1 and 6 meter and a height H’ between 1 and 6 meter. This embodiment allows the noise barrier 1 to have various sizes to optimally meet noise reduction requirements. For example, the first and second panels 2, 4 may be tall and narrow, e.g. W = 3m, H’ = 6m, or short and wide, e.g. W=6m, H’=3m, or even square for which W=H’. Depending on the application, being able to choose panel widths W and heights H’ between 1 to 6 meters provides great freedom to design a noise barrier 1 that meets specifications.
It is noted that the first and second panels 2, 4 may typically be flat or straight rectangular panels as depicted. However, in an embodiment it is conceivable that the first and/or the second panel 2, 4 is curved slightly. For example, in an embodiment the outward facing sides 8, 9 of the first and second panels 2, 4 may be concave or convex to allow for particular acoustic properties such as absorption and/or reflection.
In an exemplary embodiment it could be possible that the width W of the two panels 2, 4 is not constant between the supporting edges 6, 7 and the connecting edges 3, 5, thus wherein the width W changes in the direction of the height H’ of the two panels 2, 4.
Also, it is further noted that the height H’ of the two panels 2, 4 need not be constant along the width W, thus wherein the height H’ of the two panels 2, 4 may vary in the direction of the width W of the two panels 2, 4. As a result, a noise wall comprising a plurality of contiguously arranged noise barriers 1, 1 ’, 1 ” can change height H from a first noise barrier 1 to an adjoining noise barrier 1 ’, 1 ” in continuous fashion.
In a further aspect the present invention further relates to a method of installing a noise barrier 1 as described above, wherein the pivotable or hinged connection between the first and second panels 2, 4 allows for convenient handling and positioning. In particular, the method starts with a step of attaching the first and the second panels 2, 4 along the first and second connecting edges 3, 5 to a lifting device. In an embodiment this step may be facilitated by having the lifting member 12, e.g. a lifting lug, arranged along the first and second connecting edges 3, 5.
Subsequent steps of the method then involve lifting the first and second panel 2, 4 toward a required location and pivoting/rotating the first and the second panel 2, 4 toward the required pivot angle (a).
Without loss of generality, when lifting and moving the first and second panels 2, 4 toward the required location, it may be assumed that the noise barrier 1 is folded flat, i.e. wherein the pivot angle (a) is very close or at zero and wherein the inward facing sides 10, 11 of the first and second panels 2, 4 are substantially parallel. From this closely folded configuration of the noise barrier 1, the first and second panels 2, 4 are then rotated/pivoted with respect to each other toward the predetermined pivot angle (a).
Having reached the required pivot angle (a), the method then continues by lowering the first and the second panel 2, 4 into a final position on the ground.
According to the method, the noise barrier 1 is installed conveniently by simply lifting the noise barrier 1 using a lifting device, unfolding the noise barrier 1 toward the required pivot angle (a), and lowering the noise barrier 1 into position. In case two support beams 13 are used, then the method may further comprise the step of placing the first and second supporting edges 6, 7 into the first and second grooves 15, 16 respectively, thereby guaranteeing that the required pivot angle (a) is obtained and maintained.
