Description

[0001] The invention relates to a web for mounting on a partition wall, in particular a noise barrier on railways or roads, with brackets which are to be mounted on the uprights of the partition wall and have two superimposed bearings with which loads of the web can be introduced into the uprights, with outriggers which are arranged on the brackets, with a grating which rests on the outriggers, and with a railing whose railing uprights are fastened to the outriggers.

[0002] The invention further relates to a soundproof wall with uprights between which soundproofing elements are arranged.

[0003] Although the web according to the invention can be attached to partition walls of various types and with a wide variety of properties, the invention particularly relates to an inspection route for sound barriers where, due to local conditions, conventional accessibility for service work or necessary inspections is not available. This applies, for example, to overpass structures, sound barriers on high retaining walls, or high, steep embankments on which sound barriers are arranged. Due to the selected attachment to the steel posts of the sound barrier, the web according to the invention is primarily intended for new construction, but can also be used for retrofitting existing noise barriers or for the construction of a sound barrier on an existing structural structure.

[0004] The problem with attaching a web to the posts of a noise barrier is, among other things, that neighbouring posts are dynamically stimulated differently when a vehicle, e.g. . A train travels along a noise barrier, and tensile and compressive forces of varying magnitude act on the noise barrier, offset in time and direction of travel. These forces are transferred via the uprights into the foundation of the noise barrier. This dynamic movement of the uprights makes it difficult to install a web on the noise barrier without play or constraints.

[0005] The invention is therefore based on the object of remedying this situation.

[0006] This problem is solved by a bridge having the features of claim 1 and a soundproof wall having the features of claim 12.

[0007] Preferred, but not mandatory, features and embodiments of the invention, which - as far as functionally possible - can be combined with one another as desired, are the subject of the dependent claims.

[0008] The web according to the invention is preferably mounted by means of brackets on brackets arranged, for example, welded, to the uprights of a partition wall, in particular a noise barrier on railways or roads. Mounting the brackets on other parts or sections of uprights (for example, on flanges attached to the uprights or directly on the uprights) is also possible according to the invention, although these alternative possibilities will not be referred to separately below.

[0009] On the brackets there are outriggers on which a grating rests and to which railing posts of a railing are attached.

[0010] Due to the different loads and correspondingly different movement of neighboring uprights, the web twists, leading to stresses in the web, some of which can also be transmitted to the uprights. To prevent this, the grating rests on the cantilevers via elastic support elements, allowing the web and the grating to easily compensate for the web's twists.

[0011] In a preferred embodiment of the invention, the supports have two superimposed bearings, which can be used to transfer loads from the web to the uprights. The first bearing transmits vertical forces on the one hand and horizontal forces directed parallel to the longitudinal axis of the cantilevers on the other. The second bearing transmits essentially only compressive forces directed parallel to the longitudinal axis of the cantilevers. The second bearing has an elastic damping element.

[0012] The weight of the web is thus transferred to the uprights via the first bearing, and the torque generated by the weight of the web and the loads on it around the first bearing is transferred to the uprights via the second elastic bearing. Since the second bearing is only a thrust bearing, the entire web can be "suspended" from the uprights via the first, upper bearing without constraints, even if neighboring uprights are subject to different elastic deformations due to the dynamically varying loads, and these deformations are passed on to the web.

[0013] In order to fix the grating in the lateral direction, i.e. transversely to the longitudinal direction of the web, to the web without it being subject to constraints or rattling, a preferred embodiment of the invention can provide for the grating to be supported laterally on the brackets and / or the railing posts via elastic damping elements.

[0014] For the same reason, alternatively or additionally, it may be provided that the grating is attached to the outriggers via hold-down devices arranged on the brackets and / or the railing posts with elastic damping elements.

[0015] A further preferred embodiment of the invention can consist in the first bearing having bores with an axis parallel to the longitudinal direction of the web, through which a bolt can be inserted for connection to a post. In this case, the bolt forms a joint with the bores, around which the respective boom can pivot as far as required. Naturally, only a slight pivoting capability is required to compensate for the movement of the respective post relative to neighboring posts, which can also be compensated by the elasticity of the damping element of the lower, second bearing.

[0016] Within the scope of the invention, the brackets and the arms can be interconnected, in particular screwed, parts, made from a single part or be parts that are permanently interconnected.

[0017] In a further preferred embodiment of the invention, the railing posts are firmly screwed to the outriggers, which is advantageous for reasons of the stability of the walkway.

[0018] In order to avoid tension in the bridge as much as possible when it has to twist, the railing tubes are mounted on railing posts via elastic supports.

[0019] The width of the grating can be a single piece, and the width of the grating can correspond to the width of the web. However, in order to easily adapt the width of the grating and thus the web to specific requirements, the invention can also provide for the grating to have grating elements that run in the longitudinal direction of the web and are firmly connected to one another, preferably by screwing.

[0020] Whenever the above and the following descriptions refer to damping elements, damping properties, and the like, it should be noted that "damping" primarily refers to the elastically yielding behavior of the relevant parts, and actual damping in the sense of actively damping a vibration may, but does not necessarily, exist. The damping elements and the like may serve exclusively or partially to compensate for manufacturing tolerances through their elastic properties and to compensate for the movements of the uprights introduced into the web.

[0021] In a preferred embodiment of the invention, the elastic support elements, via which the grating rests on the outriggers, and / or the elastic damping elements, via which the grating is supported laterally on the brackets and / or the railing posts, and / or the elastic damping elements of the hold-down devices and / or the elastic supports, via which railing tubes are mounted on railing posts, can have an electrically insulating property.

[0022] In particular, it is preferred in the invention if the elastic damping elements of the second bearing and / or the elastic support elements via which the grating rests on the outriggers, and / or the elastic damping elements via which the grating is supported laterally on the brackets and / or the railing posts, and / or the elastic damping elements of the hold-down devices and / or the elastic supports via which railing tubes are mounted on railing posts, are made of electrically insulating plastic, in particular EPDM (ethylene propylene diene rubber), because EPDM has both the desired electrically insulating and elastic properties.

[0023] Further features and advantages of the invention will become apparent from the following description of preferred, non-limiting embodiments of the invention with reference to the accompanying drawings. It shows: Fig. 1 a view of a section of a soundproofing wall according to the invention with a web according to the invention, Fig. 2 a post with a cantilever to be attached thereto, Fig. 3 a post with a cantilever mounted thereon and a railing post to be attached to the cantilever, Fig. 4 the arrangement of a grating on a cantilever, Fig. 5 the arrangement of the grating in the area of ​​the holder, Fig. 6 the arrangement of the grating in the area of ​​a railing post, Fig. 7 the railing post with railing tubes, Fig. 8 a plan view of a soundproofing wall according to the invention with a crank, shown only schematically, and Fig. 9 a detail of the soundproofing wall of Fig. 8 in the area of ​​a bend.

[0024] The drawings illustrate embodiments of soundproof walls and webs according to the invention. These are, however, only examples. Apart from the inventive features as defined in the claims, many components may also be designed differently within the scope of the present invention without requiring specific mention below. In particular, components and features described in the various embodiments of the invention may be combined with one another in any way, even without this being expressly mentioned in every possible case.

[0025] Fig. 1 shows a section of a soundproofing wall 1 according to the invention with two uprights 2 made of I-profiles, between which soundproofing elements 3 are arranged. The soundproofing wall 1 can be arranged, for example, along a railway line or a road. A web 4 is mounted on the uprights 2. This web 4 can, for example, serve as an inspection route for regularly required checks. The use of the web on walls or partition walls for purposes other than soundproofing is also possible within the scope of the invention.

[0026] The footbridge has, among other things, a cantilever 5, a grating 6 and a railing 7. On the cantilever 5, as shown in particular in Fig. 2 As can be seen, a bracket 8 is arranged, for example welded. The bracket has two cheeks 9, which are welded to the side of the boom 5, and a connecting web 11.

[0027] A bracket 12 is arranged on each of the uprights 2. In the embodiment shown in the drawings, this bracket is U-shaped and is attached, e.g., welded, to the upright by the ends of its legs 13. Holes 14 are located in the legs 13, whose common axis 15 is aligned horizontally and parallel to the longitudinal direction of the web 4. Corresponding holes 16 are located in the cheeks 9 of the brackets 8. To mount the brackets 8 to the uprights 2, a bolt 17 is inserted through the holes 14 and 16 and fixed there, e.g., screwed tight.

[0028] The bolt 17 inserted through the holes 14 and 16 forms a first bearing 18 for the outriggers 5 on the uprights 2. This first bearing 18 primarily transfers vertical forces resulting from the dead weight of the web 4 and loads on it (inspection personnel, tools, etc.) and horizontal forces directed transversely to the longitudinal direction of the web 4 or parallel to the longitudinal axis of the outriggers into the uprights 2. Any forces that arise, for example, from wind acting on the web 4 in the longitudinal direction of the web 4, can of course also be absorbed by the first bearing if no separate measures are taken in this regard.

[0029] Below the first bearing 18 is a second bearing 19, which essentially only has to transmit compressive forces into the uprights 2, which arise from the weight moment of the web 4 generated around the first bearing. In particular, the second bearing should not absorb any significant vertical or horizontal forces running in the longitudinal direction of the web 4, in order to enable a constraint-free mounting of the cantilevers 5 on the uprights 2.

[0030] In order to maintain a certain freedom of movement with regard to the horizontal alignment of the booms 5 on the one hand and a movement of the uprights 2 triggered by passing vehicles (tensile and compressive forces on the opposite side of the soundproof wall 1) on the other hand, but to prevent a temporary and undesirable complete lifting of the brackets 8 in the area of ​​the lower bearing 19 from the uprights 2, an elastic damping element 21 is arranged in the area of ​​the second bearing 19, which consists of plastic, preferably EPDM, and compensates for a pivoting movement of the brackets 8 relative to the uprights 2 to the necessary extent.

[0031] At the end of the outriggers 5 opposite the bracket 8, a railing post 22 is rigidly attached. For this purpose, a mounting flange 23 is arranged on the outriggers 5, which is screwed to a corresponding counter-flange 24 on the railing post 22 ( Fig. 3 ).

[0032] The grating 6 rests on the brackets 5 via elastic support elements 25, which are made of plastic, preferably EPDM. As in particular Fig. 4 shows, the grating 6 is also supported laterally by elastic damping elements 26, 27 on the brackets 8 and the railing posts 22. In addition, as shown in particular by the Fig. 5 und 6 show, the grating 6 is attached to the brackets 8 and the railing posts 22 by means of hold-down devices 28, 29 with elastic damping elements 31, 32. In Fig. 4 only the hold-down device 28 is shown, but not the hold-down device 29.

[0033] If a cantilever 5 is located at the end of a grating 6, it is additionally held in place in the longitudinal direction by an end plate 33 screwed to the railing post 22 with a damping element 34 ( Fig. 6 ).

[0034] If a boom 5 is located in the transition area from one grating 6 to another grating 6, as in Fig. 3 As shown, a spacer 35 may be arranged on the bracket 8 and / or on the railing post 22, which extends between the adjacent gratings 6 to prevent them from colliding. Damping elements 26 may be arranged on both sides of the spacer 35, which preferably also has damping and electrically insulating properties, to laterally fix the gratings 6.

[0035] The grating 6 can have a width that extends essentially over the entire length of a cantilever 5, i.e., from the bracket 8 to the railing post 22. However, the invention prefers a grating 6 consisting of grating elements 36 that extend in the longitudinal direction of the web 4 and are firmly connected to one another, for example, by screwing.

[0036] The railing 7 consists of the already mentioned railing posts 22 and railing tubes 37, which rest on mounting plates 39, which are attached to the railing posts 22, via elastic supports 38 and are screwed tight by means of brackets 41.

[0037] The various damping elements, support elements, and supports, which are preferably made of electrically insulating plastic, in particular EPDM, not only achieve the inventive purpose of allowing the web to be mounted on the sound barrier 1 without play and without constraints, but also ensure that the individual parts or assemblies can be electrically insulated from one another in the event of electrical contact with live lines, particularly on a railway. On the other hand, however, it is also ensured that the direct electrical connection of the railing posts 22 via the cantilevers 5 to the grounded posts 2 of the sound barrier 1 also grounds these components.

[0038] While in Fig. 1 an embodiment of the invention is shown in which the uprights 2 are arranged substantially in alignment, is shown in Fig. 8 An embodiment of the invention is shown in which the soundproofing wall 1 is bent twice by approximately 30° in order to be guided around a power pole 42. The web 4 follows the contour of the soundproofing wall 1 accordingly, whereby, as Fig. 9 shows the console 12 in a similar way as with a simple upright 2 (e.g. Fig. 1 bis 3 ) is attached to a post 2a made of two interconnected I-profiles, adapted to the bend 43.
