Definitions

  • the invention relates to a support structure with the features of the preamble of claim 1.
  • the specified support structure is used to suspend at least one sound absorber from a ceiling.
  • the invention relates to a system for improving the acoustics in a room, which system comprises at least one sound absorber and a support structure according to the invention for suspending the sound absorber from a ceiling.
  • the sound absorber can in particular be an essentially plate-shaped element that is hung upright or standing from the ceiling.
  • a sound absorber is also called a "baffle", which is an English term that means baffle or sound screen.
  • baffle elements are usually suspended from a ceiling at a distance from one another and in several rows behind and / or next to one another.
  • Sound absorbers of the type mentioned above are used indoors, primarily in indoor spaces where noise is generated, so that noise reduction measures are necessary for reasons of noise and / or health protection.
  • a main area of application is therefore industrial construction or the area of industrial noise protection.
  • sound absorbers of the type mentioned above can be used to regulate the reverberation in hall-like rooms and / or as a design element in interior design.
  • Another main area of application is public buildings.
  • the sound absorbers can be made of different sound-absorbing materials. Materials such as glass, rock or wood wool as well as mineral or natural fibers are common. Materials that are not rigid are usually placed in a frame. Sound absorbers that are made of a rigid material can also be suspended from a ceiling without a frame with the help of a suitable support structure.
  • U1 is an example of a support structure formed from T-rails for suspending baffle elements.
  • the T-rails are attached to the ceiling with the crosspiece pointing downwards, so that an angle plate with a hole can be pushed onto the crosspiece.
  • the hole is used to receive a hook that is screwed into a dowel integrated into the baffle element. With the help of the hook, the baffle element can thus be hooked into the hole in the angle plate.
  • the present invention is based on the object of making the installation of sound absorbers of the type mentioned above safer and simpler.
  • a level of security should be achieved that enables the system to be used in rooms with high levels of moisture and / or dirt.
  • the alignment of the sound absorbers should be simplified during assembly.
  • the proposed support structure for suspending at least one sound absorber from a ceiling comprises an elongated support profile, a suspension device that can be connected to the support profile and means for connecting the sound absorber to the support profile, the means comprising an angle plate.
  • the angle plate has at least two legs lying at an angle, preferably at a right angle, to one another, which can be placed in a corner area of the sound absorber on two corner side surfaces of the sound absorber and can be connected to the sound absorber in a non-positive, positive and / or cohesive manner are.
  • the angle plate is connected directly to the sound absorber, preferably even before assembly.
  • the angle plate is placed in a corner area of the sound absorber on two side surfaces of the sound absorber arranged at a corner and connected to the sound absorber with a force fit, form fit and / or material fit.
  • the frictional connection can be achieved, for example, by means of a clamping force which is exerted on the sound absorber by the angle plate.
  • the angle plate can have at least one projection which engages in the sound absorber.
  • a projection can be, for example, a mandrel, pin or web formed on the angle plate.
  • the angle plate can be screwed to the sound absorber.
  • the angle plate and the sound absorber can be glued to one another.
  • the angle plate has the advantage that it has a comparatively large contact surface for connection to the sound absorber, so that a non-positive, positive and / or material connection can be easily implemented. At the same time, the security of the connection increases. Because the suspension must ensure that the sound absorbers can be permanently and securely attached to the ceiling so that people standing under the sound absorbers are not endangered by falling sound absorbers.
  • a baffle ceiling can be used to improve the room acoustics in an open station hall.
  • the baffle ceiling is exposed to climatic changes and wind loads.
  • the suspension must also withstand these increased requirements. This means that even with temperature-related changes in length and / or wind loads, it must be ensured that the means for connecting the sound absorber to the support profile remain permanently connected to the sound absorber.
  • At least one leg of the angle plate has a web for a non-positive, positive and / or material connection with the sound absorber.
  • the at least one web can, for example, be pressed into the sound absorber or inserted into a groove in the sound absorber, so that a form fit is achieved.
  • the web is preferably arranged at a free end of the leg.
  • it is preferably aligned essentially parallel to the other leg of the angle plate.
  • the other leg can also have such a web.
  • the angle plate is designed in the manner of a bracket.
  • the at least one web can alternatively serve to enlarge the contact surface for contacting the angle plate on the sound absorber.
  • the at least one web is preferably arranged on a side edge of the leg running perpendicular to the free end. Furthermore, it is preferably aligned essentially perpendicular to the first and also to the second leg of the angle plate. If a web is arranged on the opposite side edges of a leg, these can work together as a clamp, so that a clamping force can be exerted on the sound absorber via the two webs. In this way, a frictional connection can be achieved with the help of the opposing webs.
  • the angle plate is advantageously a stamped / bent part which has been produced from a sheet metal material by stamping and bending. In this way, the angle plate can be produced easily and inexpensively. In the same way, the at least one web of the angle plate can be produced so that the web does not have to be connected to the angle plate afterwards, for example by means of welding.
  • the angle plate has a bracket which runs at least in sections perpendicular to one of the two legs and / or is arranged in a plane with one of the two legs.
  • the angle plate and thus the sound absorber can be connected to the support profile.
  • the tab has also been produced together with the angle plate in a stamping / bending process.
  • at least one leg of the angle plate has a recess corresponding to the bracket.
  • the bracket is advantageously arranged in a plane with a leg, that is to say that the bracket is connected to the bracket sheet in the area of the outer corner of the angle plate.
  • the tab can have a recess for receiving a connecting means, such as a loop or a hook.
  • a connecting means such as a loop or a hook.
  • the loop or the hook can then be inserted, for example suspended, into a suitable receptacle in the support profile.
  • the angle plate itself serve as a connecting means, so that the means for connecting the sound absorber to the support profile only include the angle plate. This not only reduces the number of parts in the supporting structure, but also the installation effort, since the sound absorber can be connected directly to the supporting profile via the angle plate.
  • the tab of the angle plate is angled one or more times at the end.
  • the tab itself thus forms a kind of hook, with the aid of which the angle plate and thus the sound absorber can be inserted, in particular suspended, into a suitable receptacle in the support profile. In this way, a form fit between the angle plate and the support profile can be achieved, which secures the tab from slipping out.
  • the bracket of the angle plate have an undercut area.
  • a form fit can also be achieved via the undercut area, which secures the tab from slipping out.
  • the undercut area of the tab is preferably engaged from behind by a wall section of the support profile after it has been inserted or hooked into the receptacle of the support profile.
  • the tab can be shaped like a hammer head, for example when viewed from above.
  • the tab is connected directly to the support profile and an additional connection means is dispensed with is that the sound absorber can be aligned with the support profile at the same time via the tab. This is the case if, according to a preferred embodiment of the invention, the tab comes to rest flat against the support profile when it is inserted or hooked into the support profile. The flat contact at the same time causes a certain stiffening which counteracts a movement of a sound absorber suspended from a ceiling in this way with respect to the support profile.
  • each sound absorber is connected to a support profile at two outer corners with the help of an angle plate, alignment and stiffening of the entire system can be achieved at the same time through the flat contact of the angle plate on the respective support profile.
  • the sound absorbers align themselves at the same grid spacing.
  • the support profiles themselves are hung over the Sound absorbers aligned so that they remain permanently aligned in parallel. The system aligns itself automatically during assembly so that a uniform grid can be easily produced even with large ceiling areas.
  • the support profile preferably has at least one recess for connection to the angle plate, preferably for receiving a connecting means connected to the angle plate or for receiving the bracket of the angle plate.
  • the recess can be designed comparatively simply if the connecting means is a loop or a hook or if the tab is shaped like a hook. The lanyard or strap is then simply hooked in.
  • the recess is preferably designed in such a way that it has a wide opening area for inserting the tab and a narrower opening area underneath for receiving the narrow area of the tab.
  • the wide area of the bracket or the "hammer head” is then gripped from behind by the wall of the support profile.
  • the recess can have the shape of a rectangle, the lower edge of which is stepped in order to form the narrow opening area.
  • the recess of the support profile also has a stepped upper edge.
  • the gradation is such that a tab projecting into the recess is formed. This must be at least slightly elastically deformable so that it can be pushed away when the bracket of the angle plate is inserted into the recess.
  • the bracket of the angle plate is then lowered and inserted into the narrow opening area of the recess so that the bracket of the support profile that is pushed away during insertion can spring back into its starting position. In this position it holds down the bracket of the angle plate and thus forms an additional safeguard against slipping out.
  • the support profile preferably has a plurality of recesses arranged in a row. An angle plate can then be inserted into each recess. The distances between the recesses then determine the distances between the sound absorbers. To increase the spacing, an angle plate can only be used in every second recess.
  • the plurality of recesses are preferably arranged at equal distances from one another, so that the sound absorbers can be suspended in a grid-like manner.
  • the support profile is designed with mirror symmetry in cross section. If one long side of the support profile has recesses for receiving angle plates, the same recesses are found on the other long side.
  • the support profile can thus be connected on both long sides with angle plates or with the sound absorbers attached to them.
  • the support profile preferably has a profile section in cross section which forms a flat support surface for supporting a leg of the angle plate.
  • at least two such profile sections are preferably provided on opposite sides.
  • the support of the angle plate on the flat support surface of the support profile leads to a further stiffening of the arrangement.
  • a relative movement of the sound absorber with respect to the support profile is counteracted so that the sound absorber remains optimally aligned.
  • the support profile can, for example, have a substantially V-shaped or U-shaped cross section.
  • a support profile is designed with mirror symmetry in cross section, the mirror axis - in the assembled state - preferably running vertically.
  • flat support surfaces for supporting angle plates are formed on both longitudinal sides.
  • the opening is preferably oriented towards the room.
  • the opening can thus be used for further purposes.
  • lighting devices can be via the opening be integrated into the support profile.
  • the support profile is preferably a stamped / bent part, so that the recesses provided in the support profile can be made in one punching process.
  • the support profile can also be designed as a closed tube.
  • the support profile and / or the angle plate is or are preferably made from metal, in particular from a metal sheet.
  • a metal sheet enables production in a forming process, in particular in a stamping / bending process.
  • the metal sheet preferably has a thickness of 0.5 mm to 3 mm. In this case, the sheet metal has sufficient rigidity and, at the same time, low weight.
  • the metal sheet can in particular be a steel sheet which is preferably protected from corrosion, for example galvanized.

  • a form fit is also achieved via a screw connection.
  • a material bond can be established by means of an adhesive connection.
  • the angle plate has a comparatively large contact surface for connection to the sound absorber, so that a force-fit, form-fit and / or material-fit connection can be implemented more easily.
