Definitions

  • the innovation relates to a suspended from the ceiling of a room ceiling with longitudinally and transversely spaced, in cross-section T-shaped, a web, a head and horizontal support flanges having profile rails, between which in the respective frame formed by the profile rails of the support flanges held mineral wool panels are inserted.
  • suspended ceiling or ceiling panels that are ballproof, with which, for example, sports halls, classrooms or playrooms are equipped in daycare to avoid lifting or damaging individual cassettes in the frame grid ceiling.
  • metal sheets are inserted all over into the frame of the grid ceiling.
  • the desired ball throwing security is bought with poor acoustic properties of such a suspended ceiling.
  • a reverberant sound disturbs with detriment the mutual understanding of the persons in such a room.
  • the European patent application EP 0 652 338 A1 discloses a false ceiling in built-in with a suspended support grid, which consists of longitudinal rails and cross rails. In the fields of the supporting grid ceiling tiles are inserted. On the ceiling panels resting support rods are anchored positively at both ends to the longitudinal rails. The support rails support the ceiling panels against lifting and buckling up when under the ceiling a pressure surge arises. As a result, the fire resistance of a false ceiling is maintained even under load from a pressure surge.
  • the novelty is therefore based on the object to improve the initially described, known sub-ceiling so that it is also ball-proof in addition to the fire protection, sound-absorbing or acoustic effect.
  • At least one metal sheet bent up at least at one of its edges is arranged rearwardly at the top of the respective mineral wool plate, the edge of which is approximately as high as the web of the profiled rails minus the thickness of the mineral wool plate, so that the upper free one Edge of the sheet edge can be latched under the head of the rail, the metal sheet covering the mineral wool plate over the entire surface.
  • the lower ceiling with the known acoustic effect in addition make also ball proof, then although known metal sheets are used according to the frame size, but new is the arrangement of the metal sheets on the mineral wool panels of the suspended ceiling at the top back of the mineral wool slab.
  • known metal sheets are used according to the frame size, but new is the arrangement of the metal sheets on the mineral wool panels of the suspended ceiling at the top back of the mineral wool slab.
  • the innovation is further characterized in that the metal sheet covers the mineral wool plate over the entire surface.
  • the spaced-apart profile rails are in a conventional manner in cross-section T-shaped and form between them frames that are rectangular or square as the mineral wool boards inserted there.
  • Known is the full-surface insert of the mineral wool panels, if they are not ball-proof. Assigning a metal sheet whose area is less than or equal to the surface of the frame, then an applied thin metal sheet can ensure the desired ball impact safety, namely on the one hand by the stiffening as a result of the edges collagenkanteten and on the other hand due to the latched under the head of the rail edge.
  • the respective frame formed by the profile rails is provided for stiffening with at least one spacer which can be attached to the rear surface of the metal sheet.
  • the ball impact safety is particularly good if the metal sheet is stiff on the mineral wool plate and reliable on the Profile rail construction is maintained.
  • the head of the respective rail guarantees when snapping the edges of the metal sheet for a reliable fixing of the metal sheet, even if this has larger dimensions, if a further stiffening is provided. But this succeeds with the mentioned spacer on the back surface of the metal sheet.
  • the spacer in cross-section is V-shaped and is releasably secured by overlapping the rail with at least one pin to this, the stiffening succeeds with minimal material and simple means.
  • the V-shaped spacer may be formed so that it overlaps one or more rails, so that there is a cross-sectional view in plan view. With a pin can be attached to the rail also in a very simple and effective way of the spacer. The solubility is ensured because you can easily pull a pin along the spacer from the transverse thereto rail.
  • perforated metal sheet with full-surface back applied mineral wool or rock wool contributes to an improvement in airborne sound insulation and longitudinal sound insulation without sacrificing the rigidity and strength and thus the Ballsmithproof.
  • perforated plates holes are uniformly spaced over the entire surface of the metal sheet. Under perforation can of course but also understand the arrangement of only a few holes and different shape in the metal sheet. A good strength and rigidity is achieved even with a thickness of the metal sheet of 1 mm and a material thickness of the spacer for stiffening of 0.4 mm.
  • the perforation in the metal sheet prevents a strong return reflection of sound that could possibly have passed up from the room under the suspended ceiling up through the mineral wool panel. This return reflection can be further reduced by using a mineral wool or rock wool pad over the entire surface of the perforated metal sheet.
  • the innovation also provides that simple frame structures can be used in the construction of the suspended ceiling. It is advantageous if the respective frame of suspended support rails and perpendicular to these running, with these connected connection profile rails is formed. These profile rails can be made of a 0.3 mm thick sheet steel with perfect function and high reliability.
  • edge of the metal sheets is crimped at an angle not equal to 90 °.
  • the upper edge of the sheet edge should engage under the head of the rail and press the sheet metal in this way largely rigid and resiliently against the rear upper side of the mineral wool slab.
  • the spring effect is particularly favored when the angle of the bead is not equal to 90 °, d. H. the flat surface of the edge is oblique to the main plane of the metal sheet.
  • the outer dimension of the cassette formed by the metal sheet 2 mm smaller than the grid, and the projection of the slope of the canted edge is between 1.97 mm to a maximum of 10 mm. It has been found that labor and especially the cost of materials is minimal when working with the above-mentioned grid, which then you should make the outer dimension of the cassette formed by the metal sheet 2 mm smaller.
  • the resilient elastic clamp at the edge of the metal sheet is particularly favorable, taking the range of the projection dimension shown in FIG , 97 mm to 10 mm limited.
  • the new ceiling can also easily, effectively and reliably attach to the side walls, especially if it is envisaged that the rails for mounting a vertical wall of the room in cross-section C-shaped Have wall profile rails that hold down the metal sheet against the mineral wool plate via resiliently biased holder.
  • the wall profile rail preferably has the cross section of a box open on one side, wherein its closed side is to bring laterally against the vertical wall in abutment and on the opposite side of the rail is open. From the open side, on the one hand, the mineral wool slab and, on the other hand, the resting metal sheet is pushed into the space of the profiled rail.
  • the inserted edge of the metal sheet is not flared at this wall-side attachment point.
  • the spring-biased holding down of the metal sheet under pressure takes place in the region of the wall profile rail by the mentioned resiliently biased Holder. This presses on the one hand on the metal sheet and on the other hand is supported against a leg of the C-shaped wall rail.
  • FIG. 1 is a partially constructed in a conventional manner profiled rail system for a renewal under cover shown.
  • the space formed by vertical walls, a horizontal ceiling and a horizontal floor is not shown. But you can see two suspended from the ceiling, nonius pendant hangs.
  • Nonius connectors are components with which a good accuracy and thus the desire of one ceiling level to another can be achieved.
  • FIG. 1 are mounted at the lower end of this per se known Noniusab detoxr 1 perpendicular to these and horizontally extending support rails 2.
  • About lugs 3, which are attached to the opposite ends of connecting profile rails 4, the in FIG. 1 shown grid construction are created.
  • the support rails 2 have at their ends couplings 5, so that you can build by juxtaposing longer support rails 2.
  • connection profile rails 4 which can be attached by means of the lugs 3 on the support rails 2 via slots 6.
  • the distance from one support rail 2 to the other is 625 mm in a typical example. This measure also applies to the distance between the one connecting profile rail 4 to the adjacent, so that thereby a frame 7 can be formed.
  • This in FIG. 1 with the arrow 7 generally designated frame is between the four cross points of the support rails with the connection profile rails. The resulting field is in FIG. 1 square.
  • FIG. 2a one recognizes the support rail 2, as well as in FIG. 2b shown connecting profile rail 4 in cross-section T-shaped. Both rails 2 and 4 have in the middle of a web 8, above a head 9 and horizontally extending support flanges 10.
  • the in the FIGS. 2a and 2b shown T-profiles are double-rolled and preferably in the case of a visual construction, ie if you see the rails 2, 4 of the ceiling from below, provided with a rolled-coated sheet metal strip 11.
  • On the support flanges 10 are shown in the representation of FIGS. 1 . 3 . 5 and 6
  • Mineral wool plates 12 placed the lower, visible from the bottom space surface is preferably provided with holes for sound absorption.
  • a metal sheet 13 is arranged at the rear on top of the respective mineral wool panel 12.
  • the support rails 2 are suspended.
  • FIGS. 1 and 3 covers the metal plate 13 extending horizontally with its main part the frame 7 and thus the respective mineral wool plate 12 over its entire surface.
  • the main frame covers the surface of the frame 7 largely and has on the four sides four edges 14 personallykantete, while in the illustration of the FIG. 1 the structure top right with the smaller field has a metal sheet 13 with only three edges 4 personallykanteten.
  • the fourth side projects with its edge 15 in a cross-sectionally C-shaped wall rail 16, which will be described later.
  • the edge 14 of the metal sheet 13 is flat in the embodiment shown here and in plan view clearly in FIG. 4 visible, noticeable. There, the holes 17 are shown, so that a metal sheet 13 as a perforated plate results.
  • FIG. 1 In the FIG.
  • the metal sheet 13 is stiff on the rails 2 and 4 on the respective mineral wool slab 12, so that even when the impact on the mineral wool slab from the room from bottom to top, the metal sheet 13 can absorb the forces.
  • the mineral wool plate 12 can not be lifted or damaged from the frame 7 by such an impact of an article.
  • the metal sheet 13 absorbs the shocks.
  • the Nonius pendants 1 are designed stiff and fixed to the ceiling, so that the impact of a ball on a mineral wool plate 12 from the room from bottom to top could not lead to dents or even a bending Verniuspenders.
  • the frame 7 is provided with a spacer 19.
  • This is in cross-section V-shaped, wherein the edge of the V rests on the rear surface of the metal sheet 13, on which one in FIG. 1 looks. From the cross-sectional view of FIG. 3 is also clearly seen that the edge or crease line 20 of the V rests in contact with the metal sheet 13 on the back surface thereof.
  • the V-shaped spacer 19 has from the side of its kink 20 at opposite ends a respective recess 21, as can be seen in FIG. 1 sees. With this recess 21, the spacer 19 is fitted over the connecting profile rails 4, so that their distance from each other is fixed.
  • the projected height H of the edge 14 of the metal sheet 13 is 12 mm in this embodiment.
  • FIG. 1 the attachment of the suspended ceiling is illustrated on the right in a broken representation on a vertical wall, not shown. At this a wall rail 16 is fixed. This has in cross-section C-shape or the shape of a one-sided open box, as in cross-section in the Figures 5 and 6 is shown.

  • the wall profile rail 16 is mounted on its closed side, ie the back, on the vertical wall, not shown, so that from there under the formation of the C-shape below the horizontally extending support leg 23 projects and projects at the upper end of the counter-pressure arm 24.
  • a mineral wool plate 12 is first inserted horizontally so that it comes to rest on the support leg 23.
  • the metal sheet 13 is placed in the manner described above, which may be perforated as in the embodiments shown here, may be unperforated or provided with only a few recesses and z. B. made of sheet steel or aluminum.
  • the side edge 15 of the metal sheet 13 is not upended, but rather closes the free edge 15 in approximately flush with the mineral wool plate 12, as can be clearly seen in the Figures 5 and 6 recognizes.
  • V-shaped spacer 19 is provided which is inserted in the wall portion with its one end in the C-shaped wall rail 16 so that its edge 20 of the V on the surface of the metal sheet 13 to lie comes, how to look in perspective FIG. 1 sees.
  • FIG. 6 shows On the top are the free edges of the V of this spacer 19 in the vicinity of the counter-pressure leg 24.
  • the distance of this upper free edge of the spacer 12 as shown in FIG FIG. 6 of the counter-pressure leg 24 is characterized by the schematic character of FIG. 6 shown, there may possibly also give a touch there. But certainly the lower edge 20 of the spacer 19 contacts the surface of the metal sheet 13, and in FIG. 6 the distance shown there is conditioned by the schematic nature of this drawing.
  • the wall-side end of the spacer 19 is thus held down by the counter-pressure leg 24 on the metal sheet 13, and at the opposite end overlaps the V-shaped spacer 19 as shown in FIG FIG. 1 the connecting profile rail 4, in the web 8 a hole not shown is provided through which, including a hole in the canted edge 14 of the metal sheet 13, the pin 22 is inserted to fix the spacer 19 to the connecting rail 4.
