Description

[0001] Angle connectors

[0002] The invention relates to an angle connector according to claim 1.

[0003] It's common to build houses or other buildings from wood. Both the side walls and the supporting ceiling are made of wood. Wood has characteristics that people perceive as very positive. Wood is also a purely biological building material, and wooden structures are therefore beneficial in many ways, both in daily use and in their long-term impact on humanity.

[0004] Furthermore, it is also common practice to use sheets made of different materials, especially steel or aluminum alloys, for various purposes in construction. Such sheets often serve as coverings or as components of panels, shafts, containers, room units, etc.

[0005] However, wood and metal sheets also have pronounced acoustic properties, which mean that wooden parts and sheets often resonate in frequency ranges that are audible to humans. Wood and / or sheets transmit structure-borne sound or vibrations relatively well in certain frequency ranges, which leads to oscillations or vibrations in these frequency ranges being transmitted to other parts of the building. The vibration is then transferred, for example, from a side wall to a ceiling, the sound-radiating area increases and extends to several rooms in a building. In particular, vibrations such as those caused by floor vibrations, impacts against a side wall, or simply by footsteps or jumping on a ceiling are transmitted to other wooden parts of the building and generate noise in large parts and different rooms of the building in question.

[0006] Many people see this as a disadvantage. The modern world is full of noise in the ambient air and structure-borne sound vibrations. This noise can often be heard throughout the entire wooden building and disturbs the people inside. Sheet metal, which is part of a ventilation system, for example, and therefore has contact with the environment, also transmits noise indoors. This can lead to such a building being perceived as unpleasant and rejected. Methods are now known to limit the propagation of sound in a room. This is usually achieved by additional internal construction of the room with walls and ceiling made of plasterboard, which are installed parallel to the load-bearing walls and ceiling. However, this not only reduces the area or interior volume of the room, but also replaces the wood on the interior surfaces with plaster.As a result, the room loses the characteristics of wood that people find pleasant.

[0007] AT 524 008 A1 discloses an angle connector comprising two legs and a damping element, wherein the two legs are connected to each other by means of the damping element. The damping element is not designed without any openings.

[0008] The disadvantage of a non-perforation-free design of the damping body is that bodies penetrating or passing through the damping body cause a notch effect on the damping body, which negatively affects the durability and integrity of the damping body.

[0009] The object of the invention is therefore to provide an angle connector of the type mentioned at the outset, with which the disadvantages mentioned can be avoided, with which the structure-borne sound transmission in timber construction and / or in sheet metal parts of a building can be reduced, and which also meets mechanical requirements for a connecting element.

[0010] According to the invention, this is achieved by the features of patent claim 1.

[0011] This can significantly reduce the transmission of structure-borne sound within a wooden building. This can also reduce the transmission of structure-borne sound via sheet metal parts into a building. This can be used to create connections between the side walls of a building and the ceiling of the building, which have only a very low acoustic vibration transmission. This can significantly reduce the transmission of sound, noise or sound within the building or from one room to another. Structure-borne vibrations of the side wall, caused by a floor vibration or a sudden force, can be considerably attenuated when they are transmitted to the ceiling. In tests, the body vibration at the transition from the side wall to the ceiling was improved by around 6.5 dB(A) compared to commercially available comparable parts. This corresponds to a halving of the volume.

[0012] Studies have shown that a perforation-free design of the damping body can reduce or prevent the formation of cracks on or in the damping body, allowing the angle connector to be used over a long period of time and providing a sound-reducing effect. This allows a particularly strong, purely material-to-material connection to be formed between the first and second sides of the damping body and the first and second connecting parts, completely eliminating the need for additional physical fasteners, such as extensions that penetrate the damping body, or screws or bolts.

[0013] Despite this reduction in the transmission of acoustic vibrations, the wood remains unchanged as a load-bearing building material. This eliminates the need to cover the entire interior of the side walls and ceiling. This makes it possible to create rooms or houses in which the load-bearing wood can remain visible and tangible, yet are still – to a specified extent – ​​acoustically decoupled from neighboring rooms or the surrounding environment. This allows the advantages of wood as a building material to be utilized without being exposed to sound or noise pollution. The angle connector also represents a secure mechanical connection and is easy to install. Furthermore, it has been proven that the elasticity of the angle connector, combined with the mechanical properties of the wood, means that such buildings can withstand vibrations, such as those caused by earthquakes, better than particularly rigid, connected comparable buildings.

[0014] The subclaims relate to further advantageous embodiments of the invention. Express reference is hereby made to the wording of the patent claims, whereby the patent claims are incorporated into the description at this point by reference and are deemed to be reproduced verbatim.

[0015] The invention will be described in more detail with reference to the accompanying drawings, in which only preferred embodiments are shown by way of example. In the drawings:

[0016] Fig. 1 shows a first preferred embodiment of an angle connector in question in an axonometric view;

[0017] Fig. 2 shows a second preferred embodiment of an angle connector in an axonometric view; and

[0018] Fig. 3 is a schematic representation of a building ceiling which is connected to a building side wall by means of an angle connector.

[0019] 1 and 2 each show preferred embodiments of an angle connector 1 for connecting a building ceiling 14 to a building side wall 15, wherein the angle connector 1 comprises a first component 2, a second component 3 and a damping body 5, wherein the first component 2 has a first fastening section 6 and a first connecting part 7, wherein the first fastening section 6 has a predeterminable number of first openings 8 for a first fastening of the angle connector 1, wherein the second component 3 has a second fastening section 9 and a second connecting part 10, wherein the second fastening section 9 has a predeterminable number of second openings 11 for a second fastening of the angle connector 1, wherein the damping body 5 is designed without openings, wherein the first connecting part 7 is connected to a first side 12 of the damping body 5,and wherein the second connecting part 10 is connected to a second side 13 of the damping body 5, opposite the first side 12. Fig. 3 shows a preferred application of such an angle connector 1. This allows the transmission of structure-borne sound within a wooden building to be significantly reduced. This allows connections to be formed between the side walls 15 of a building and a ceiling 14 of the building, which have only a very low acoustic vibration transmission. This allows the transmission of sound, noise, or noise within the building or from one room to another to be significantly reduced. Structure-borne vibrations of the side wall 15 of the building, which may have been caused by a ground vibration or a sudden force,can thus be significantly attenuated during their transmission to the building ceiling 14. In tests, the physical vibration at the transition from the building side wall 15 to the building ceiling 14 could be improved by approximately 6.5 dB(A) compared to commercially available comparison parts. This corresponds to a halving of the volume.

[0020] Studies have shown that a perforation-free design of the damping body 5 can reduce or prevent the formation of cracks on or in the damping body 5, allowing the angle connector 1 to be used over a long period of time and providing a sound-reducing effect. This allows a particularly strong, purely material-to-material connection to be formed between the first and second sides 12, 13 of the damping body 5 and the first and second connecting parts 7, 10, whereby additional physical connecting elements, such as extensions that penetrate the damping body 5, or screws or bolts, can be completely dispensed with.

[0021] Despite this reduction in the transmission of acoustic vibrations, the wood remains unchanged as a load-bearing building material. This does not require the entire interior of the building's side walls 15 and ceiling 14 to be covered. Rooms or houses can therefore be created in which the load-bearing wood can remain visible and tangible, yet are nevertheless – to a predefined extent – ​​acoustically decoupled from neighboring rooms or the surroundings. This allows the advantages of wood as a building material to be utilized without being exposed to sound or noise pollution. The angle connector 1 also represents a secure mechanical connection and is easy to process. Furthermore, it has been proven that the elasticity of the angle connector, together with the mechanical properties of the wood, means that such buildings can withstand vibrations, for example from earthquakes, better than particularly rigid, connected comparable buildings.

[0022] The present angle connector 1 is a device for the force-transmitting and / or position-securing connection of a building ceiling 14 to a building side wall 15. The building side wall 15 is a wall, in particular a load-bearing wall, of a building. The building ceiling 14 is a ceiling, in particular a load-bearing ceiling or ceiling accessible to people, of the building. The building ceiling 14 and the building side wall 15 preferably consist of or comprise wood, but can also consist of concrete and / or comprise steel and / or aluminum alloy parts. In particular, the building ceiling 14 and / or the building side wall 15 are partially composed of pieces or sections of tree trunks, which are uninterrupted, in particular along the vertical extent of the building side wall 15. The angle connector 1 thus connects two parts of a building that are arranged at an angle to one another.Hence the name angle connects.

[0023] The angle connector 1 comprises a first component 2, a second component 3 and a damping body 5.

[0024] The first component 2 has a first fastening section 6 and a first connecting part 7. The first component 2 is provided in particular for fastening the angle connector 1 to the building ceiling 14. For fastening the first component 2 or the angle connector 1, the first fastening section 6 has a predeterminable number of first openings 8. The first openings 8 are preferably holes with a substantially circular cross-section, which are produced, for example, by drilling or punching.

[0025] The second component 3 also has a second fastening section 9 and a second connecting part 10. The second component 3 is provided in particular for fastening the angle connector 1 to the building side wall 15. For fastening the second component 3 or the angle connector 1, the second fastening section 9 has a predeterminable number of second openings 11. The second openings 11 are preferably holes with a substantially circular cross-section, which are produced, for example, by drilling or punching.

[0026] The angle connector 1 or the first and second components 2, 3 can have different dimensions. Preferably, a width 23 of the angle connector 1 is provided in a range between 100 and 300 mm. The preferred maximum height 24 of the angle connector 1 is between 100 and 200 mm. Figs. 1 and 2 show two preferred embodiments of an angle connector 1, which differ in terms of their proportions and dimensions. The length 22, the width 23, and the height 24 of the angle connector 1 are shown as examples in Fig. 1. As can be seen, the angle connector 1 shown in Fig. 2 is wider than the angle connector 1 shown in Fig. 1.

[0027] Preferably, the width 23 of the angle connector 1 can be at least 50 mm, preferably at least 100 mm.

[0028] Preferably, the width 23 of the angle connector 1 can be a maximum of 400 mm, in particular a maximum of 350 mm, preferably a maximum of 300 mm.

[0029] Preferably, the height 24 of the angle connector 1 can be at least 50 mm, preferably at least 100 mm.

[0030] Preferably, the height 24 of the angle connector 1 can be a maximum of 300 mm, in particular a maximum of 250 mm, preferably a maximum of 200 mm.

[0031] Preferably, the width 23 of the angle connector 1 can be at least 0.8 times, in particular at least 1.2 times, preferably at least 1.5 times, the height 24 of the angle connector 1.

[0032] Preferably, the width 23 of the angle connector 1 can be a maximum of 3 times, in particular a maximum of 2.5 times, preferably a maximum of 2 times, the height 24 of the angle connector 1.

[0033] Preferably, the length 22 of the angle connector 1 can be at least 30 mm, in particular at least 50 mm, preferably at least 70 mm. Preferably, the length 22 of the angle connector 1 can be a maximum of 150 mm, in particular a maximum of 100 mm, preferably a maximum of 80 mm.

[0034] Preferably, the height 24 of the angle connector 1 can be at least 1.5 times, in particular at least 2 times, the length 22 of the angle connector 1.

[0035] Preferably, the height 24 of the angle connector 1 can be a maximum of 3 times, in particular a maximum of 2.5 times, the length 22 of the angle connector 1.

[0036] It is preferably provided that an angle connector 1 with dimensions in the range of that described above, which is attached to a building side wall 15, is capable of a relative mass of at least 0.18 N / mm 2 , in particular at least 0.28 N / mm 2 , preferably at least 0.40 N / mm 2, without the angle connector 1 suffering any damage within 24 hours. In this context, permanent deformation or reshaping is already considered damage. This does not affect the connection of the angle connector 1 to the building side wall 15, but only the angle connector 1 itself.

[0037] The first and second components 2, 3 are preferably metal parts, although fiber composite materials or other materials may also be provided.

[0038] Particularly preferably, the first and / or the second component 2, 3 consists of steel, in particular S235 JR or S250 GD or S275 or S355 or DX51 D, or stainless steel or an aluminum alloy, in particular EN AW-5754 (AlMg3) H111.

[0039] The angle connector 1 serves to connect two parts of a building which are or should be arranged at a specific angle to one another, whereby this angle can vary depending on the design of the building. The angle connector 1 must therefore be connected to or fastened to both parts of the building with their fastening sections 6, 9. It is preferably provided that the first fastening section 6 is arranged at a predeterminable first angle 4, in particular between 75° and 180°, preferably substantially 90°, to the second fastening section 9. This enables fastening to widely used embodiments of a building.

[0040] This also allows for use in a building where the building ceiling 14 follows a sloping roof or is parallel to it. If the angle 4 is essentially 180°, the first fastening section 6 is essentially parallel to the second fastening section 9.

[0041] This first angle 4 between the first and second fastening sections 6, 9 can be achieved in different ways by means of different designs on the angle connector 1. It has proven to be advantageous and, above all, easy to manufacture if the first component 2 is designed such that the first fastening section 6 is arranged at the first angle 4 to the first connecting part 7. Since the first angle 4 is then already completely ensured by the first component 2, the second component 3 can be designed to be straight in a certain way, wherein the second component 3 is preferably designed such that the second fastening section 9 and the second connecting part 10 are arranged essentially in the same plane or parallel to one another.

[0042] The damping body 5 is designed without any perforations. In particular, the damping body 5 also has no blind holes. The damping body 5 is therefore free of mounting openings for detachable and / or adjustable fasteners, in particular screw receiving openings. This also includes notches created by a screw itself when it is screwed directly into a soft material.

[0043] The damping body 5 can consist of or be formed from different materials. The damping body 5 should have certain acoustic or vibration-damping properties. The damping body 5 preferably has a Shore A hardness between 35 and 100. With regard to the materials, the damping body 5 itself can be formed in different ways, for example comprising at least one elastomer and / or a plastic and / or a viscoelastic polymer and / or a rubber-elastic polymer. It is particularly preferably provided that the damping body 5 comprises a plastic foam, in particular a closed-cell plastic foam, preferably a closed-cell PU foam. This has proven advantageous both with regard to the vibration-damping properties and also the mechanical load-bearing capacity and long-term strength. The damping body 5 can have different shapes orCross sections, however, it is provided that the damping body 5 has at least a first side 12 and a second side 13. The first side 12 lies opposite the second side 13. In particular, it is provided that the first side 12 of the damping body 5 is arranged substantially parallel to the second side 13 of the damping body 5. This is the case with the preferred basic shape of a damping body 5 in the form of a cuboid. The first and second sides 12, 13 preferably have a rectangular shape.

[0044] Preferably, the damping body 5 can be at least 2 mm thick, in particular at least 2.5 mm thick. The thickness of the damping body 5 extends from the first side 12 to the second side 13.

[0045] Preferably, the damping body 5 can have a maximum thickness of 30 mm, in particular a maximum thickness of 25 mm. These minimum and maximum thickness values ​​have proven particularly advantageous in tests, particularly using closed-cell PU foam as the damping body 5, with regard to the damping properties and durability of the damping body 5.

[0046] Preferably, the damping body 5 can be substantially six millimeters thick. Studies have shown that an angle connector 1 with a six-millimeter-thick damping body 5, particularly when using closed-cell PU foam as the damping body 5, provides particularly good sound absorption and meets the static requirements particularly well.

[0047] The first component 2 and the second component 3 are connected to one another by means of the damping body 5 and only by means of the damping body 5. For this purpose, it is provided that the first connecting part 7 is connected to the first side 12 of the damping body 5, and that the second connecting part 10 is connected to the second side 13 of the damping body 5. Since the damping body 5 is designed without any openings, these connections are not physical connections. In particular, it is provided that the first connecting part 7 is connected to the first side 12 of the damping body 5 free of one or more physical connecting means, in particular free of screw connections. Furthermore, it is also preferably provided that the second connecting part 10 is connected to the second side 13 of the damping body 5 free of one or more physical connecting means, in particular free of screw connections.Body-free connections have proven to be very advantageous when structure-borne noise needs to be interrupted or at least significantly reduced.

[0048] To connect the damping body 5 to the components 2, 3, it is preferably provided that the first connecting part 7 is integrally connected to the first side 12 of the damping body 5, and / or that the second connecting part 10 is integrally connected to the second side 13 of the damping body 5. In particular, it is provided that these connections are only or exclusively integrally formed, and the integral connection does not simply serve to secure a screw connection.

[0049] Material-to-material connections include gluing, soldering, welding, and vulcanization. Particularly preferably, the first connecting part 7 is glued to the first side 12 of the damping body 5, and / or the second connecting part 10 is glued to the second side of the damping body 5. Loctite 480 or other plastics with the chemical base ethyl cyanoacrylate are used as adhesives, for example. The adhesives are not shown in Figs. 1 to 3.

[0050] As can be seen in Figs. 1 and 2, the first connecting part 7 is designed without any openings. Furthermore, it is provided that the second connecting part 10 is designed without any openings. The first connecting part 7 and / or the second connecting part 10 preferably have no recesses and / or openings.

[0051] Fig. 3 shows a schematic view of an arrangement comprising a building ceiling 14 and a building side wall 15. The building side wall 15 or wooden wall shown as an example is fastened to the substrate 20 by means of a schematically shown support 21. Only an end section of the building ceiling 14 or wooden ceiling shown as an example is shown. The building side wall 15 and the building ceiling 14 are part of a preferred building in which the building ceiling 14 rests at least indirectly on the building side wall 15. An angle connector 1 is fastened to a first inner surface 17 of the building side wall 15 and to a second inner surface 18 of the building ceiling 14. In particular, the angle connector 1 is screwed to the building ceiling 14 and / or the building side wall 15, although nailing, in particular with comb nails, can also be provided. In Fig.3 shows dashed lines 16 which are intended to illustrate the position of the respective screws.

[0052] It is preferably provided that a predeterminable plurality of angle connectors 1 are arranged on the building side wall 15 and the building ceiling 14. It has proven advantageous if the distance between two angle connectors 1 arranged directly one after the other is between 300 mm and 1500 mm, preferably between 500 mm and 1000 mm.

[0053] The angle connector 1 can be arranged in at least two different positions or orientations on the building ceiling 14 and the building side wall 15. It has proven advantageous for structure-borne sound insulation, especially of ambient noise but also of ground vibrations, for the damping body 5 to be arranged parallel to the building side wall 15, in particular the first inner surface 17.

[0054] Alternatively, the damping body 5 can be arranged parallel to the building ceiling 14, in particular the second inner surface 18. This has proven advantageous in insulating the transition of motion sound, which arises at the building ceiling 14, to the building side wall 15.

[0055] The structure-borne sound insulation can be further improved if the building ceiling 14 does not rest directly on the building side wall 15. The term "directly resting" refers to direct physical contact between the building ceiling 14 or the wood of the building ceiling 14 and the top or bottom of the building side wall 15 or the wood of the building side wall 15. It has proven particularly advantageous to arrange a wall-damping body 19 between a top or bottom or support surface of the building side wall 15 and the building ceiling 14. This is also shown in Fig. 3. The wall-damping body 19 preferably comprises closed-cell plastic foam.
