Definitions

  • the invention relates to a hanging element for backdrop ceilings according to the preamble of claim 1
  • the well-known hanging elements for backdrop ceilings of this training are prism-shaped acoustic beams that are used for ceiling lining in industrial buildings and at the same time are used as a walk-in false ceiling.
  • Your view cover consists of a perforated PVC film.
  • this publication makes no statements about a special shape and arrangement of the vertical plate used to form the T-shaped support; on the contrary, it must be assumed that the plate is a flat structure and that the span of these elements can only be increased by changing the plate dimensions.
  • the hanging elements for backdrop ceilings of the type mentioned at the outset have proven their worth, but it is not possible to use them for larger spans based on the fact that the above hanging elements are suspended by means of rope-shaped fastenings which engage the elements at the top. It goes without saying that the assembly work is then the cheapest and a suspension is generally easier to carry out if the hanging elements have the greatest possible length.
  • the invention has for its object to design the hanging elements according to the preamble of claim 1 so that they have a greater length and can therefore be assembled more easily.
  • the aim continues to be low production costs for the hanging elements, which have excellent sound absorption properties.
  • the hanging elements enables spans of up to approximately 15 m without fear of undesired deformations and distortions.
  • the plate mentioned takes on a special shape in the interior of the hanging element; it should not be flat, but - when viewed from above or in a horizontal section - be designed in a wave-like or zigzag shape, the waves also being square, rectangular or trapezoidal.
  • the plates designed in this way are then firmly connected locally to the metal profiles located above by means of rivets or the like, in order to create a T-beam.
  • An approximately U-shaped profile made of metal can also be provided at the lower end, which encloses the lower end of the plate shaped in the aforementioned sense.
  • This profile is also expediently fixed e.g. connected to the plate by riveting.
  • a modification of the hanging element according to the invention provides for a special design of a metal profile located at the lower edge of the hanging element. Based on the invention, this can be designed in such a way that it forms a double T profile together with the aforementioned T profile, the metal profile below also being designed such that it extends predominantly horizontally. In addition, this profile is also connected to the centrally arranged plate so that it cannot slide and pull. Riveting is also an option here, which is particularly useful for the thin-walled aluminum materials used.
  • Hanging elements of this type are used to reduce the sound level e.g. used in production rooms, they are hung as a backdrop under the ceiling of the room, which can be used for wires, ropes or the like, which attack the elements at the top.
  • the elements are therefore not underpinned or supported from below, because this is impossible with an arrangement under a ceiling.
  • the hanging elements must be light, but at the same time rigid, so that they can be suspended and assembled over longer lengths in a self-supporting manner.
  • An essential component of these elements are predominantly laterally arranged plate-shaped bodies 1, which can also have horizontal sections 2 located at the top and sections 3 arranged at the bottom, wherein shaping is possible by angling a larger plate.
  • These bodies 1 are preferably made of mineral fibers, which have laminated cover layers to desired upper to be able to maintain surface properties.
  • a profile 4 made of light metal or the like is provided at the upper edge of the hanging element, to which the suspension elements, which are not shown in more detail, normally also act .
  • the profile 4 is formed by an overhead plate 5, which is equipped with two spaced apart legs 6, which are directed downwards.
  • a sheet 7 made of light metal or the like engages in the space between the two legs 6, which is designed in a wave shape and, as shown in FIG. 2, has successive trapezoidal press-ins 8 which form laterally alternating planar sections 9, which on the inside of the legs 6 rest and also come to rest at the lower end on the upward legs 10 of a continuous, uninterrupted over the length of the hanging elements U-profile 11.
  • the sections 9 are arranged both on the top and bottom of the profiles 4 and 11 by rivets 12 push and pull resistant.
  • the sections 2 lie on the inside of the profile 4 and the sections 3 on the bottom of the web of the profile 11. So that the laterally arranged body 1 are at a distance from the centrally arranged plate 7.
  • This design leads to very good sound absorption properties, at the same time the profiles 4 and 11 together with the profiled plate 7 form a T-beam, which the hanging element a good one Bending rigidity against bending gives and spans of 15 m.
  • the width of the plate 5 also be kept so low that only part of the sections 2 is covered. So the side edges of the plate 5 can also end at x.
  • a sinusoidally shaped plate 7 according to FIG. 3 can also be used. It is appropriate to rigidly connect the adjacent metal parts at the top and bottom.
  • a light metal profile is also provided at the bottom of the hanging element, which is designed according to the profile 4, but additionally has edges 13 which are angled laterally upwards, in order to be able to hold the body 1 better. Since the sheet 7 is in turn firmly connected to the profiles 4 at both the lower and the upper edge, a double-T beam results.
  • Fig. 5 also shows a double-T beam with the profiles 4 and the sheet 7 together with only laterally arranged sound absorbing plates in the form of the body 1st
  • the embodiment according to FIG. 6 shows a modified version for the lower edge of the hanging elements.
  • the profile 11 according to FIG. 1 also has a t-shaped projection 14 for receiving the lower sections 3.
  • the upper profile 4 has hollow points 15 between the bodies 1 and the sheet metal 7, specifically for the formation of hollow, longitudinal box-like supports.
  • These overhead profiles 4 are characterized by increased rigidity in the vertical and horizontal directions.
  • the bodies 1 can also be arranged close to the plate 7 and, if necessary, touch it.
