Definitions

  • the invention relates to a suspended ceiling, in particular for the arrangement in a building, with a supporting structure, which consists of at least two support rails, arranged at right angles to the support rails and releasably connected to the support rails cross rails and parallel to the support rails extending, each two adjacently arranged transverse rails connecting Intermediate rails, wherein the cross-sectionally T-shaped mounting rails, crossbars and intermediate rails form a grid with rectangular areas, in the insulation boards, the carrier rails, cross rails and intermediate rails facing first formed as a visible surface have large surface area, are inserted in such a way that they rest on horizontally extending transverse webs of the transverse rails, mounting rails and intermediate rails, and wherein hangers are arranged on the mounting rails, cross rails and / or intermediate rails.
  • Such ceilings are known from the prior art and are arranged in many ways, especially in the area of interiors, wherein a supporting structure with insulation boards on hangers with the building, in particular a building ceiling is connected.
  • the structure is arranged at a predetermined distance from the building so that a cavity is formed between the structure and the building.
  • the dead load of such suspended ceilings including any installations is limited to ⁇ 0.5 kN / m 2 .
  • any stresses due to wind suction or wind pressure must be taken into account when loading the ceilings.
  • Such stresses are of course also to be considered in closed rooms of buildings, as far as can not be detected wind stress here.
  • open windows or frequently opening doors or gates are responsible for this.
  • a combination of open windows and frequently opening doors and gates leads to high wind loads, which are difficult to calculate, so that the corresponding construction elements must be sufficiently stable and thus designed with a high weight.
  • suspended ceilings usually takes place for sound insulation reasons or to create cavities between the suspended ceiling and the building, which cavities previously installed pipe, ventilation ducts, cables or the like record and are covered by the suspended ceiling.
  • the suspended ceiling has additional aesthetic effects.
  • suspended ceilings also serve to reduce the energy required to heat such rooms with high ceilings.
  • both the sound insulation of the suspended ceiling ceiling building ceiling as well as the transmission of noise from the cavity between the suspended ceiling and the building ceiling can be reduced.
  • suitable insulation boards beyond the sound transmission line between adjacent rooms can be mitigated with a common cavity between the building ceiling and the suspended ceiling.
  • the sound insulation and speech intelligibility in the rooms is characterized by the so-called reverberation time. Sound insulation and speech intelligibility are u.a. significantly influenced by the sound absorption levels of the insulation boards at different frequencies. Since this effectiveness is in the foreground, are used as insulation boards so-called acoustic panels.
  • Ceilings according to the invention have a supporting structure which consists of metal profiles. These metal profiles may according to standards have a deflection of at most 1/500 of their span, ie the suspension distance, with a limitation of the deflection of 4 mm is provided.
  • the load-bearing capacity of the metal profiles is determined by bending tests at different spans and loads in both directions. Centrally attached forces, deflections and spans will give the flexural rigidity and allowable Bending moment and thus also the permissible load calculated by the cover layers.
  • Such metal profiles consist of 0.4 mm thick hot-dip galvanized strips or sheets, for example made of soft unalloyed steels or aluminum alloys, but which have a minimum material thickness of 0.5 mm.
  • the metal profiles are connected to the building via hangers.
  • the hangers can be designed, for example, as simple wires, spring tension hangers, threaded rods or so-called vernier hangers, which are steel or aluminum hangers with telescoping subelements.
  • the number of hangers depends on the load capacity of the metal profiles, which are designed as mounting rails, cross rails and intermediate rails and which carry the load-bearing insulation boards. In practice, it has been shown that for each 1.5 m 2 ceiling surface at least one hanger is required.
  • the metal profiles namely the support rails, cross rails and intermediate rails are arranged at right angles to each other and connected to each other.
  • the mounting rails, cross rails and intermediate rails form a grid with rectangular areas whose size match the size of the insulation boards to be inserted.
  • the insulation boards are laid in such a way that they rest on horizontally extending transverse webs of the transverse rails, mounting rails and intermediate rails.
  • a connection between the insulation boards and the structure is usually not provided, as in the course of maintenance work to be carried out and / or additional installations in the cavity an unhindered, ie easy to open access must be present.
  • the aforesaid acoustic panels consist of blends of artificially produced glassy solidified fibers, namely so-called glass wool or rockwool fibers, which are made with a large proportion of expanded perlite using binders made from starch.
  • such acoustic panels have a proportion of up to 40% by mass of expanded perlite, up to 30% by weight of glassy solidified fibers, up to 15% by mass of starch, up to 10% by mass of kaolin, up to 5% by mass of cellulose fibers or cellulose fibers Paper and up to 5% by mass of crystalline SiO 2 or sand.
  • the average bulk density of such acoustic panels is about 256 kg / m 3 and can be up to 400 kg / m 3 . Because of the binding of mineral fibers and perlite with starch derivatives, these acoustic panels are sensitive to moisture and, for example, react with swelling. The glassy solidified fibers serve as reinforcements in these acoustic panels, and these acoustic panels tend to sag due to their swelling effect and, in particular, their own weight. The maximum size of such acoustic panels is therefore very limited, taking into account their respective thickness. Due to their tendency to sag and large contact surfaces are required to prevent falling out of the acoustic panels from the structure. Overall, the use of such heavy insulation boards therefore leads to heavy use of the structure and in particular the hanger, the number of which must be increased by the high weight of the insulation boards to achieve the necessary stability of the suspended ceiling.
  • mineral wool ceiling panels which consist of bonded glass fibers.
  • mineral wool ceiling panels are distinguished according to their fiber material, after which Glass wool mineral wool ceiling tiles are to be distinguished from rock wool mineral wool ceiling tiles.

  • acoustic panels made of mineral fibers, which are produced in a wet process.
  • the mineral fibers are arranged in relatively dense packing with densities of more than 130 kg / m 3 flat to the large surfaces of the acoustic panels, so that the acoustic panels have high tensile strengths in the direction of the two horizontal spatial axes and sufficient rigidity.
  • the transverse tensile strength of these acoustic panels is not high, but is sufficient to form durable flat acoustic panels. In order to achieve a sufficient bending strength, high binder amounts are required.
  • Such acoustic panels are offered as standard with the dimensions 600 mm x 600 mm or 600 mm x 1,200 mm, each with a thickness of 22 mm for a structure with 24 mm wide straps.
  • the edge portions of these acoustic panels are either oriented perpendicular to the large surfaces or have a gradation, which is arranged in the region of the visible surface, so that the support of the structure above the plane of the room-side surfaces of the acoustic panels are arranged.
  • Usual steps have a height of 7 mm.
  • the large bulk density of the above-described acoustic panels requires correspondingly stable support in the structure or a high number of suspension points in order to achieve the required stability of a corresponding suspended ceiling.
  • the US-A-3,202,077 describes a suspended ceiling, in particular for the arrangement in a building with a supporting structure, which consists of mounting rails, a perpendicular to the support rails extending rail and a plurality of parallel to the support rails or to the transverse rails extending intermediate rails, so that a supporting structure with a grid rectangular surfaces limited, with individual insulation boards are inserted in this grid.

  • the structure consists of DIN rails and at right angles to extending crossbars, the crossbars and the DIN rails are formed in cross-section T-shaped and form a grid with rectangular areas.
  • an insulation board is inserted, which consists for example of slag wool. It can easily be seen that these insulation boards have a length of about 1200 mm and a width of about 600 mm, so that either the support rails at a distance of about 1200 mm and the cross rails at a distance of about 600 mm or the cross rails at a distance of about 1200 mm and the support rails are arranged at a distance of about 600 mm. It follows that the distance between the adjacently arranged mounting rails is formed in any case between 1800 mm and 1875 mm.
  • the invention has for its object to design a generic ceiling such that in particular the number of carrier rails and the hanger is lowered, and at the same time remains in the durability of the ceiling at optionally easier mounting rails, cross rails and the intermediate rails.
  • the insulation boards consist of binder-bound mineral fibers, in particular rock wool and a density between 70 kg / m 3 and 140 kg / m 3 , in particular between 70 kg / m 3 and 115 kg / m 3 , a thickness between 10 mm and 40 mm, in particular between 12 mm and 15 mm and a basis weight between 1.3 kg / m 2 and 3.2 kg / m 2 have that adjacent support rails at a distance between 1800 mm and 1875 mm to each other are arranged, that the insulation boards on their visible surfaces a lamination of a fiberglass random web and on a second large surface opposite the visible surface have a thin and sound transparent coating.

  • the inventive design of the suspended ceiling with the specified basis weight of the insulation boards leads to a reduction in the hanger, which can be arranged due to the low basis weight of the insulation board in a relatively large distance from each other.
  • the commonly used insulation boards have dimensions of 600 mm x 600 mm or 600 mm x 1,200 mm. This can be arranged between two adjacent support rails two or three insulation boards. With a distance of 1,875 mm between the rails, insulation boards measuring 625 mm x 625 mm or 1,250 mm x 625 mm are provided. But it is also possible to use insulation boards, which are made longer with the same width and, for example, 1,500 mm to 2,400 mm long.
  • the weight of the structure is significantly reduced. Overall, therefore, there is a combinatorial effect of the reduced weight of the structure and the insulation boards used with the specified basis weight.
  • the hangers of a support rail, transverse rail and / or intermediate rail are arranged at a distance from each other of 1,200 mm.
  • the hangers are attached to the support rails, so that, for example, provided a distance between the adjacent support rails of 1,875 mm and a distance of the hangers on the mounting rails of 1,200 mm two hangers are provided on an area of 2.25 m 2 .
  • the support rails have at their ends corresponding connecting elements, which preferably allow a plugged connection behind one another arranged mounting rails.

  • the support rails have openings distributed uniformly over their length, which serve to receive plug-in elements arranged on the cross rails at the end.
  • the plug-in elements are inserted from both sides of the support rails in the corresponding openings and connect the crossbars form fit with the mounting rails, without, for example, a screw or the like required.

  • the orientation of the mineral fibers in the insulation boards and the high content of binders cause a sufficiently high dimensional stability, which is maintained even at relatively high moisture contents of the ambient air.
  • the insulating board on its the support rails, crossbars and intermediate rails facing designated as a visible surface large surface of a lamination of a fiberglass random web.
  • This lamination is especially fully or partially glued to the insulating board.
  • the lamination has a different color from the insulation board color, which is preferably formed by an order of a dispersed in water paint. But there are also insulation boards with unhindered visible surfaces usable. If the glass fiber random web is untreated, the basic color of the fiberglass mat and the translucent insulation board characterize the appearance. A colored design of the fiberglass mat can be provided before bonding with the insulation board.
  • the second large surface of the insulating panel facing the visible surface has a thin and sound-transparent coating, in particular in the form of a fiberglass mat.
  • the rigid structure of the insulating board of mineral fibers, which has already been given, is additionally improved by the glued-on, tension-resistant and, to a certain extent, pressure-resistant glass fiber random web.
