Description

[0001] The invention relates to a support profile arrangement for supporting soundproofing elements.

[0002] Such a carrier profile arrangement is known, for example, from DE 10 2013 019 031 A1.

[0003] Soundproofing elements are well known in the art. Soundproofing elements are used wherever high noise levels occur. This is particularly true for traffic routes such as roads or railway lines, but also at airports. Tunnels are also often equipped with soundproofing elements to prevent sound from being reflected from the tunnel walls back onto tunnel users. Soundproofing elements are preferably made from a metallic base structure with additional sound-absorbing elements. In addition to acoustic effectiveness, a structurally sound and durable construction is also required, which should also be as simple to manufacture as possible. The soundproofing walls are installed by anchoring support profiles into the ground at specific intervals. The profile spaces, which are often U-shaped, face one another. The soundproofing elements are inserted between the parallel support profiles.The support profiles enclose the ends of the elements. A disadvantage of conventional soundproof walls is that matching support profiles must be manufactured for the different soundproof elements to ensure secure support. This results in high manufacturing effort and high costs.

[0004] The object of the invention is therefore to provide a support profile arrangement suitable for supporting soundproofing elements of various dimensions, in particular of various thicknesses. Furthermore, the support profile arrangement should enable simple and quick installation of the soundproofing elements. Overall, a structurally sound, durable, and cost-effective construction of a soundproof wall should be ensured.

[0005] This object is achieved by a support profile arrangement having the features of claim 1. Advantageous embodiments are the subject of the dependent claims. It should be noted that the features listed individually in the claims can also be combined with one another in any technologically expedient manner, thus demonstrating further embodiments of the invention.

[0006] The support profile arrangement according to the invention for supporting soundproofing elements comprises a support profile, preferably designed as a double-T support, and at least one spacer profile arranged on the inside of a flange of the support profile. The support profile arrangement is characterized in that the spacer profile has a trapezoidal cross-section with two base sides and two legs, wherein the spacer profile rests against the flange of the support profile with a first base side and the second base side forms an acute angle with an adjacent leg. The second base side forms a receiving surface for holding a soundproofing element.

[0007] The support profile arrangement according to the invention has the advantage over the prior art that the trapezoidal design of the spacer profile provides the largest possible support surface for the soundproofing elements. The support surface can extend along the entire length of the legs. The surface reaches up to the web of the support profile. The ends of the soundproofing elements can thus be securely received and held by the support profile. This ensures a structurally safe and durable construction.

[0008] Advantageously, the support profile is a double-T beam. The double-T beam has two U-shaped support spaces. At least one spacer profile is arranged in each support space. The spacer profile is located on the inside of a support flange. Ideally, the spacer profiles are arranged on the same side of the beam, running along one plane. It is also conceivable that a spacer profile is arranged in each of the U-shaped support spaces on the inside of the opposing support flanges.

[0009] Preferably, the leg that forms the acute angle with a base side, preferably with a base, i.e., the longer of the two base sides, is arranged adjacent to the web of the support profile. This allows the receiving surface for the soundproofing element to extend right up to the web, thereby maximizing the receiving surface. Such a design also makes it possible for the transition between the flange and the web of the support profile to be rounded. This allows stress peaks on the support profile to be reduced, giving the support better mechanical strength and thus allowing it to withstand higher loads.

[0010] Advantageously, the spacer profile is a rectangular trapezoid. This ensures that the spacer profile provides the largest possible support surface for soundproofing elements, while also not extending beyond the width of the support profile.

[0011] The acute angle is preferably between 55° and 65°. It is particularly preferably approximately 60°. This allows for a particularly advantageous ratio between the connecting surface between the flange of the support profile and the first base side and the receiving surface. This ensures a structurally safe and durable construction of a soundproof wall.

[0012] Ideally, the spacer profile is designed as a hollow profile. This design offers the advantage that the spacer profile has a damping effect and can absorb vibrations. Passing trains or motor vehicles transmit high dynamic loads in the form of pressure and suction effects through the sound barriers or sound barrier elements into the foundations. These dynamic loads have a significant impact on the durability of the sound barriers. The hollow spacer profiles can largely prevent the transmission of sound vibrations to the support profiles, thereby increasing the service life of the sound barriers. The spacer profile advantageously has a strip thickness of 2 to 4 mm, preferably 3 mm.

[0013] Preferably, the base side of the spacer profile, which rests against the flange, has a gap or recess extending in the longitudinal direction of the support profile. The spacer profile can accommodate fasteners through the gap, allowing it to be attached to the support profile. Ideally, the gap extends along the entire longitudinal extent of the spacer profile. Preferably, the gap has a constant width.

[0014] The support profile can have at least one opening on a flange, which is preferably designed such that it forms a passage for receiving a connecting means with the gap in the spacer profile. The opening is preferably suitable for receiving screws or pin-shaped connecting means. For this purpose, it has a round cross-section. The opening can be designed with or without a thread. Ideally, the support profile has a plurality of openings arranged in a row and preferably extending along the longitudinal direction of the support profile, so that the spacer profile can be attached to the support profile over the entire length of the spacer profile.

[0015] The support profile arrangement according to the invention has at least one threaded plate. The at least one threaded plate ensures secure fastening of the spacer profile to the support profile. The threaded plate, together with the opening and the gap, preferably forms a passage for a connecting means. Ideally, a screw is arranged in the passage, which engages with its external thread into an internal thread of the threaded plate. Advantageously, the at least one threaded plate is arranged in the spacer profile. The threaded plate is preferably designed as a parallelogram. At least one angle of the threaded plate is between 70° and 80°, ideally it is 75°. The threaded hole is preferably arranged at the intersection point of the diagonals, in the center of symmetry. This can largely prevent the threaded hole from breaking out.To make the threaded hole more robust and durable, the threaded plate can be coated. Advantageously, the support profile arrangement comprises a plurality of threaded plates arranged along the spacer profile, each of which interacts with an opening.

[0016] The spacer profile can be designed as a bent part. The spacer profile is preferably made of flat metallic material. By forming, ideally by bending, the spacer profile is given the shape required for its function. Spacer profiles designed in this way save material and therefore costs. If the spacer profile is designed as a bent part, the gap can be formed by bending the spacer profile so that it has two end sections, which preferably form the first base side of the spacer profile. The end sections run in one plane and are arranged at a distance from one another. The distance between the end sections forms the gap.

[0017] The invention and the technical environment are explained in more detail below with reference to the figures. It should be noted that the figures show a particularly preferred embodiment of the invention. However, the invention is not limited to the embodiment shown. In particular, the invention encompasses, to the extent technically feasible, any combination of the technical features listed in the claims or described in the description as relevant to the invention.

[0018] They show: Fig. 1 schematic plan view of a carrier profile arrangement according to the invention in one embodiment, Fig. 2a / b schematic plan views of spacer profiles according to the invention in different designs, Fig. 3 Top view of a threaded plate in one embodiment.

[0019] Fig. 1 shows a schematic plan view of a support profile arrangement 10 according to the invention in one embodiment. The support profile arrangement 10 comprises a double-T support 12 having two U-shaped support spaces 20, wherein the support space 20 is formed by a web 18 and two flanges 14, 16. At least one spacer profile 24 is arranged in each support space 20. The spacer profile 24 is arranged on an inner side 22 of a support flange 14. Ideally, the spacer profiles 24 are arranged on the same side of the profile 12 and extend along one plane.

[0020] The spacer profile 24 is designed as a hollow profile. This design offers the advantage that the spacer profile has a damping effect and can absorb vibrations. The spacer profile 24 has a trapezoidal cross-section, ideally a rectangular trapezoidal cross-section, with two base sides 36, 38 and two legs 40, 42. The spacer profile 24 rests with a first base side 36 against the flange 14 of the support profile 12. The second base side 38 forms an acute angle with a leg 42, which is arranged adjacent to the web 18 of the support profile 12. The angle α is preferably 60°. The second base side 38 forms a receiving surface for holding a soundproofing element (not shown).

[0021] Preferably, the base side 36, which abuts the flange 14, has a gap 26 or recess extending in the longitudinal direction of the support profile 12. The gap 26 allows the spacer profile 24 to receive fasteners, allowing it to be attached to the support profile 12. Ideally, the gap 26 extends along the entire extent of the spacer profile 24. Preferably, the gap 26 has a constant width.

[0022] The support profile 12 has at least one opening 30 on the flange 14, which opening is preferably designed such that, together with the gap 26 of the spacer profile 24, it forms a passage for receiving a connecting means 28. The opening 30 is preferably suitable for receiving screws. For this purpose, it has a round cross-section. The opening 30 can be designed with or without a thread. Ideally, the support profile 12 has a plurality of openings 30 that are arranged in a row and preferably extend along the longitudinal direction of the support profile 12. This makes it possible to fasten the spacer profile 24 to the support profile 12 over the entire extent of the spacer profile 24.

[0023] The support profile arrangement 10 according to the invention has at least one threaded plate 32 arranged in a cavity of the spacer profile 24. The at least one threaded plate 32 ensures secure attachment of the spacer profile 24 to the support profile 12. The threaded plate 32, together with the opening 30 and the gap 26, preferably forms a passage for a connecting means 28.

[0024] The Fig. 2a and Fig. 2b show plan views of spacer profiles 24 according to the invention in different configurations. Since the spacer profiles 24 are not fixed to a specific size, different-sized support profiles 12 do not always have to be used for supporting soundproofing elements of different thicknesses. It is sufficient to simply fasten spacer profiles 24 of different thicknesses in the support spaces 20, which compensate for the size difference between the soundproofing element and the support profile 12. Ideally, the spacer profiles 24 are designed as bent parts, preferably made of flat metallic material. Through bending, the spacer profile 24 is given the shape required for its function. If the spacer profile 24 is designed as a bent part, the gap 26 can be formed by the spacer profile 24 having two end sections 37', 37", which preferably form the first base side 36.The end sections 37', 37" extend in one plane and are arranged at a distance from one another. The distance between the end sections 37', 37" then forms the gap 26.

[0025] Fig. 3 shows a top view of a threaded plate 32 in one embodiment. The threaded plate 32 is preferably designed as a parallelogram. At least one angle of the threaded plate 32 is 75°. The threaded plate 32 has a threaded bore 34, which is preferably located at the intersection point of the diagonals, in the center of symmetry. This largely prevents the threaded bore 34 from breaking out. To make the threaded bore 34 more robust and durable, the threaded plate 32 can be coated.
