Definitions
- the invention relates to a sound-absorbing false ceiling with a supporting structure made of parallel basic profiles and parallel supporting profiles which are slidably fastened to them and which cross the basic profiles, with individual rigid plates which are fastened to the supporting profiles without a space, and with a visible side of the false ceiling, decorative porous coating applied on site.
- Sound-absorbing suspended ceilings are known, which are composed of individual chipboards. Support structures are provided for suspending the individual plates, into which the plates are inserted or which engage in grooves on the plate edges.
- Such blankets always have a pattern that results from the shapes of the individual plates, which are mostly square or rectangular, but can also have any other shape, for example a triangular or a hexagonal. With such ceilings, it is problematic to connect the ceiling to the wall in the case of irregular room boundary walls (eg inclined walls or rounded walls). The pattern of the ceiling resulting from the individual panels is not always architecturally desirable.
- Acoustic chipboards have the advantage, however, that they are sound-absorbing and have a high level of stability against impact and pressure loads.
- a sound-absorbing false ceiling of the type mentioned at the outset, which has no pattern, is also known (company publication "The seamless acoustic ceiling” from Stotmeister GmtH from 09/10/84).
- This known false ceiling consists of perforated gypsum boards which are fastened to a supporting structure in the usual way, the gypsum boards abutting one another tightly.
- the bottom ceiling of the thus formed ceiling is covered with a glass fiber fleece in order to be able to optically close the holes in the gypsum boards with the decorative, sound-permeable coating to be subsequently applied.
- the false ceiling must be covered with a sound-absorbing material in the form of thick mats made of glass wool or other sound-absorbing material during the assembly of the plasterboard.
- the invention has for its object to provide a sound-absorbing ceiling of the type mentioned, which can be produced with as few steps as possible and is insensitive to shock loads and does not occur in the discoloration due to locally deposited dust.
- the plates themselves are porous and sound absorbing and consist of wood shavings or organic fiber materials connected by a binder or of wood shavings with proportions of inorganic materials, that the plates are tightened by tongue and groove connections are glued to each other in a pressure-stable manner and that the decorative porous coating is applied directly to the plates.
- a false ceiling designed in this way has great stability, since it consists entirely of mechanically stable plates that have no perforations.
- the work involved in installing the false ceiling is relatively low, since the sound-absorbing effect of the panels means that it is not necessary to deposit it with sound-absorbing material, and the decorative porous coating can be applied directly to the panels mounted on the support profiles in one operation.
- the organic fibrous materials can preferably consist of flax and hemp shives or straw.
- the plate dimensions can vary within relatively wide limits.
- the dimensions specified in claims 5 to 7 are advantageous. With plate thicknesses according to claim 5, sufficient stability is obtained even with large-area plates. Plate surfaces according to claim 6 are still easy to manufacture and handle, but large enough to achieve good work progress during assembly. Rectangular plates, in particular those in the form of elongated rectangles, are particularly favorable, as specified in claim 7. Such panels are installed in the association. Since the plate shape is no longer visible on the finished ceiling, the plate dimensions can be selected with a view to particularly advantageous processing, that is to say they can be designed to be relatively large, with an elongated rectangular shape achieving particularly unproblematic laying.
- the plates are advantageously screwed to the support profiles (claim 8). Countersunk screws are advantageously used for this purpose.
- the screw heads are advantageously covered with an elastic putty (claim 9). This enables the ceiling panels to be easily attached.
- the covering with an elastic putty ensures that even if the screws are moved somewhat relative to the support profiles due to the unavoidable expansion movements of the plates, the decorative porous coating, for example a plaster layer, does not tear open.
- a supporting structure made of basic and supporting profiles which can be displaced relative to one another allows displacements within the suspended ceiling construction without the risk of tearing loose at the fastening points, e.g. Fittings, takes place.
- the plates can also have a non-combustible coating (claim 13).
- a non-combustible coating (claim 13).
- the false ceiling according to the invention can be adapted to any room shape, e.g. also on obliquely angled walls or on rounded walls.
- Expansion joints are advantageously provided in order to avoid compressive and tensile stresses within the suspended ceiling or to reduce them in the case of very large suspended ceilings (claims 14, 15).
- the overall sound-absorbing false ceiling designated U comprises panels D and a supporting structure T, which is composed of basic and supporting profiles crossing at right angles.
- a plate D should first be considered with reference to FIGS. 4 to 6.
- the plate D has the shape of an elongated rectangle of width b and length 1.
- the ratio of b: 1 can e.g. be like 1: 6.
- the total area of the ceiling tile can e.g. approx. 2 square meters.
- the thickness s of the plate D can e.g. 18 mm. It is assumed here that the plate essentially consists of wood chips which are connected to one another by an adhesive.
- the plate shown in Fig. 4 has two grooves 1 and two springs 3.
- the springs 3 of a plate can be suitable engage in grooves in adjacent plates.
- 5 and 6 can also be understood to be partial sections of two adjacent plates. The connection between these plates is then shown in an exploded view.
- the tongue 3 according to FIG. 5 can fit into the groove 1 according to FIG. 6, the tongue being pushed in so far that adjacent plates lie against one another without joints.
- the support structure T consists of a plurality of mutually parallel upper base profiles 4 and a plurality of likewise parallel bottom support profiles 5 which cross the top base profiles 4 at right angles. All base and support profiles 4 and 5 have the same C-shaped cross section with a web 6 and legs 7, 8, which are bent at an acute angle at their edges, whereby edge bends 9, 10 are formed, which point towards the web 6.
- the edge folds 9, 10 are anchored under angle anchors 11, 12. These are hook-shaped at their upper ends and overlap the edge folds 9, 10 of the upper basic profiles 4.
- This type of suspension allows the lower supporting profiles 5 to be displaced in the longitudinal direction of the upper basic profiles 4, which is indicated by the double arrows 13.
- the lower support profiles 5, but also the upper base profiles 4, can be assembled in the longitudinal direction and have the design shown in FIG. 8 for this purpose. It is assumed that FIG. 8 shows a lower support profile 5.
- This support profile is composed of profile pieces 5a, 5b and a profile connector 14. There may also be more than two profile pieces and more than one profile connector 14.
- the profile connector 14 has an approximately U-shaped cross-section and engages with its upper edges the edge folds 9, 10 of the profile pieces 5a, 5b. Lower edges 15, 16 engage in the inner edges 17, 18 of the profile pieces 5a, 5b, whereby an exact telescopic guidance of the intermediate piece 14 in the profile pieces 5a, 5b is achieved.
- the support profile 5 is shortened and extended by partially pulling off the profile connector 14.
- the upper basic profiles 4 are suspended from a bare ceiling in a known manner. Suspension points 2 are shown in Fig. 1.
- expansion joints 26 are provided along the walls. These expansion joints are covered by strips 27 which are attached to the wall 25 in question. In very large rooms, the false ceiling is divided into fields, between which there are expansion joints 28. Such expansion joints are bridged by springs 29, which are preferably firmly anchored in a plate D'1 and slidable in an adjacent plate D'2. The spring 29 has for this purpose in the groove 30 of the plate D'2 game.
- the surface is leveled, if necessary, e.g. by sanding and possibly filling. Excess glue that escapes at the joints is removed as soon as the individual panels are laid.
- a decorative porous coating 31 e.g. a layer of plaster applied. After that, the false ceiling is finished.
