A invention relates to a ceiling element (1) for a ceiling (D) consisting of several ceiling elements, comprising a lower metal support (4) which is divided up by links (7) and has holes; and an active sound layer (5) which is arranged in the metal support. The layer is a sound insulation layer or a sound absorption layer for example, especially in the form of an open-pore foam such as a melamine-resin foam. The active sound layer (5) is bonded to the metal support (4). According to the invention, the adhesive (6) is only applied to the link areas (11) and only the inner surfaces of the link areas (11) are bonded. This guarantees a simple, economical construction.

Description

The invention relates to a ceiling element according to the features of Preamble of claim 1.

Ceiling elements of the type mentioned in principle are in different configurations known. They become cover forming used in a building, starting from a floor ceiling, a form so-called suspended ceiling. The space between Floor ceiling and suspended ceiling can be advantageously for a use covert leadership of supply cores. Also carries the suspended Ceiling usually features such as lights, speakers and Sound insulating. It is in this respect to DE 44 30 292 A1 directed. In this known embodiment, the sound-active layer with the metal pad jammed.

Furthermore, it is known from EP 0 664 365, a ceiling element of two to form flat arranged on one another plate elements, which by means of a an acoustic barrier layer forming adhesive layer with each other are connected.

The object of the invention is to provide a structurally simple, economically favorable Specify design.

This object is achieved in the subject matter of claim 1.

The openings of the metal support are kept adhesive-free. So here no floating particles can klebeanhaften. The proportional area measure for Arrest of the metal overlay on the sound-active Layer can be minimized greatly. Nevertheless, there is one well-bearing composite before. Even something over the edge the webs or land areas going adhesive shares are negligible; they are not worth mentioning Reduction of the opening of the openings. The are sized so that no adhesive membrane is formed. The grid-like network structures given crossing points usually fall slightly larger in terms of area. This results in correspondingly larger adhesive surfaces for the Adhesive. While using a bottom metal pad the sound-active layer only in the context of Breakthroughs can be seen, can also be a solution to the effect that an upper metal support provided is and that the sound active layer with this is glued. The metal overlay is the storey ceiling like that closer than the one worn by her on the underside sound-active layer. Concerning the bonding lie the same advantages if the upper metal support By webs divided openings and the Bonding is performed only in the area of the webs. Appropriately consist of upper and lower metal support Expanded metal. May be a different Fine mesh of the expanded metal be provided. Even a solution to that effect is conceivable that for a Ceiling element find two metal supports use. The procedure is that the lower metal support and the upper metal support only by means of the sound-active Layer are connected. The latter acts as Retaining bridge. Moreover, it is favorable that the lower Metal pad and the upper metal pad in comparison for the extension of the area, moreover, an angled edge area have that at an angle of 30 to 45 ° to go. So a kind of shell edge is achieved. By appropriate deep drawing at the same time the surface stability of the ceiling element increases. Then it is provided that the angling of the Abwinklungs edge region goes to the sound-active layer. Either stiffening as well as in terms of a precise Attaching the ceiling element proves in a carrier work it turns out to be beneficial that the angled edge area edge edge side merges into a flattening. That lies space parallel to the dominant remaining area extension. For equal insulation or absorption effects also going to the periphery of the ceiling elements to ensure that continued the sound-active layer continuously into the bending edge area is applied. Um Also in the bending edge area a contour-corresponding course to get the sound-active layer will continue suggested that the angled edge area after Bonding of the sound-active layer with the metal overlay is formed.

On a ceiling element for one of several ceiling elements composite ceiling, with one by webs divided apertures having lower metal support and one in the metal pad sound-active layer, such as sound insulation or Sound absorption layer is an advantageous embodiment achieved by an upper metal support. The results in a particularly viable solution, with large Area measures can take hold. Again, it is intended that the upper metal support divided by webs Having openings. A particularly stable solution occurs when the top metal support with the bottom Metal support is connected at the edge. You can even to a folding or folding box-like "cage" for the sound-active layer arrive when the connection hinged at one edge and opposite is positive. Form-fitting goes in his Meaning up to a locking connection. The advantage This solution also exists in the possibility of a New or repackaging the layer of this ceiling element. Is such further handling not desired, so it is sufficient that the upper metal support and the lower metal support, for example, simple are connected cohesively. Thought is here Welding or spot welding. Even a soldering can be used as a connecting means. In terms of the upper metal support can already explain that special design are chosen by the also upper metal support consists of expanded metal. Assignment to advantage concerning the ceiling elements the further embodiment that the upper metal support comprising free-standing mounting portions. Such Bracket sections are on opposite edge areas formed. Here is on an environment, speak the other ceiling elements not positionally influencing Notchability respected. Exist in detail Such measures are that a mounting portion in vertical projection with the lower metal support is trained. The lower metal pad covers so the Holding means of the view withdrawn. It is also planned that the opposite edge areas Mounting sections in vertical projection on the one hand within and outside the lower one Metal support are formed. Concrete is so Proceeded that the Rücksprungmaß of a support portion the protrusion amount of the other support portion corresponds to the adjacent ceiling element. Notching facilitating with respect to the ceiling element proves the measure that when vertical Projection inside the lower metal pad below the holding portions a Aushebefreiraum for a Auswinkeln a ceiling element from the ceiling is trained. The corresponding maneuvering serving discharge space is sufficiently dimensioned, if he in the vertical direction about half the thickness corresponds to a sound-active layer. Finally is nor provided that the support sections through Double layer are solidified. It is under Use of the basic technical concept a simple Means to hand by the double layering by edge folding achieved. The upper metal support points the required sufficient plastic deformability required on. In addition, the cut edge of the Expanded metal disappears. Related injury risk is thereby minimized.

The ceiling of a Ceiling system comprises several identically designed ceiling elements 1.

The ceiling D acts against a floor ceiling as parallel, suspended false ceiling.

From the floor ceiling, not shown, go bottom side directed support rails 2. At least they are bottom side realized as a T-profile. The vertical one Direction of the ceiling space interspersed by the T-bridge of the profile. In the horizontal direction extend protruding on both sides of the T-legs. Their top is used as a support shoulder 3 for the ceiling elements 1.

According to the first embodiment, the ceiling element 1 from a lower metal support 4. Overlying runs a sound-active layer 5.

The lower metal support 4 is richly broken.

Metal support 4 and sound-active layer 5 are about of equal area size, where essentially a square plan is selected. It is a matter of imported sizes. Regarding the sound active layer 5 is a sound insulation layer or a Sound absorption layer, in particular in the form of a open-pored foam material. For example, or Preferably, a melamine resin foam is used.

The sound-active layer 5 is with the metal support. 4 connected. There is a bond in the contact area of metal overlay 4 and layer 5. The corresponding Adhesive 6 is shown in FIGS. 5 and 6 as Exaggerated layer recognizable, clarified through a point grid.

The adhesive 6 is only on webs 7 and web intersection points 8 of the latticework shown in Fig. 1 is present. The divided by such webs 7 openings 9 of the latticework, respectively the metal support 4, are not filled by adhesive 6. Such window-like Breakthroughs can be generated by punching his. However, one of a section is preferred a stretched expanded metal realized Metal support 4. Fig. 1 gives the selected expanded metal structure again. There are the openings 9 rhombus-shaped. Their acute-angled inside corners open up the already mentioned web intersection 8 from. This are in the position shown in Fig. 1 in the horizontal wider than the shortest side distance measured cross-section of a web 7. Accordingly is the bonding at intersections 8 reinforced. In addition, there is a recoverable from the expanded metal structure Trench 10, running in the direction of the acute-angled Inner corners of the openings 9. Here you will find recognizable a partial lager thickening of adhesive 6 instead. There is a kind of glue nest.

So also as congruent to the latticework of 4 designed adhesive grid realized arresting means stops the outside of the inner surfaces of the web areas 11 lying visible surface 12 adhesive-free.

The openings 9 are chosen as large as the area Closing films can not occur (comparable to membrane-enclosed wreath of a bubble machine). The figures in the enlargements 5 and 6 nevertheless in Area of perforations 9 continuously drawn Adhesive layer shows only the narrow sides of this layer. The visible surface 12 is sound active free. Even up the narrow sides 13 of the flat webs 7 going shares Adhesive 6 gives no clogging of the salmiakpastillenförmigen Breakthrough 9.

In reversal of the described conditions regarding Metal support 4 and sound-active layer 5 may alternatively an upper metal support 4 may be provided (not ) Shown. The sound-active layer 5 is with this glued in the same way. The Adhäsionswirkung of Adhesive 6 is sufficient to then the entire surface visible, now hanging sound-active layer 5 to hold. This one is relatively light and hangs over tied the adhesive 6 of the upper metal support 4, at the bottom of this gridwork.

This upper metal support 4, like the one shown in FIG. 1 illustrated lower metal support 4 by webs. 7 divided openings 9, where also the Gluing only in the area of the webs 7 and of course also the web intersection 8 is performed.

When forming the lower metal support 4 and upper Metal support 4 made of expanded metal is also the choice with regard to the fine mesh of the expanded metal. It For example, aluminum is used.

Another alternative is the, both broadsides of sound-active layer 5 with metal supports 4 of the described Kind of to defend. The lower metal support 4 and the upper metal support 4 are only mediating the sound-active layer 5 via one layer at a time Adhesive 6 connected. The foam structure of Layer 5 has sufficient ply strength for this purpose. The lower metal support 4 is also limited capable of vibrating.

As can be seen in FIG. 4, the lower metal support 4 peripherally angled in the direction of the floor ceiling. A such angling leads practically to an S-shaped Edge profile, referred to as angled edge region 14. It is realized around the clock. The according to outwardly rising edge 15 of the edge region 14 closes an angle of 30 to 45 ° to the general horizontal extension plane of the ceiling element. 1 on. Opposite flanks 15 diverge to the said Storey ceiling.

If only lying on top metal support 4 would be the same Conditions are taking effect.

This also applies to the version, which two, about the intermediate sound-active layer 5 connected Metal pads 4 inserts.

The basic version as well as the two variants is then own, that the bending of the Abwinklungs edge region 14 each to the sound-active layer 5 out runs, however, at the top metal support 4 in opposite directions.

Also in the basic version and also in the two Variants is a training made or vornehmable, which is that the Abwinklungs edge region 14 edge edge side merges into a flat 16. This corresponds essentially to the length of Flank 15 and extends parallel to the rest of the space planar surface area of the ceiling element 1. The bending edge area 14 is shown in Fig. 1 by dotted lines Lines indicated.

as the figures 5 and 6 further removed, is the sound-active layer 5 continuously up to the Abwinklungsbereich 14 pulled through, to the edge 17 of the ceiling element 1 going. Also the adhesive 6 go through there. The layers are so up in the Periphery held tightly together.

Fig. 5 shows an edge part of the ceiling element 1 before the formation of the angled edge region 14, Fig. 6 the relevant execution after deep drawing. The Flattening 16 can be used as a support section for support shoulder 3 serve.

The adhesive 6 may, for example, by the in Fig. 3rd indicated spray 18 can be applied. It is not even a layer-forming spray necessary. It is sufficient if the spray 18 facing web areas 11 get individual adhesive stains. Also, for example, meandering Guidance of the spraying device 18 spares, so that only a hatch-like adhesive button is present.

Now to the subject according to the second embodiment: This in the figures 7 to 12, which is also the conceptual Interpretation of the first embodiment available are shown ceiling element 1 for one of several Ceiling elements 1 composite ceiling D included also a partitioned by webs 7 openings 9 having lower metal support 4. The latter takes a sound-active layer 5 matching blank. This ceiling element 1 is now shown assigned to upper metal support 4.

With regard to the sound-active layer 5 is here too a sound insulation layer or sound absorption layer. This upper metal support 4 can, as Fig. 1 illustrates, divided by webs 7 openings 9 and thus has also land crossing points 8th.

The folding box-forming two-layeredness of this ceiling element 1 provides an embodiment according to which the upper metal support 4 with the lower metal support 4 bordered. The sound-active layer 5 is between both parts sandwiched as it were. If desired irreversible training, the Edge connection be realized by crimping, i. the Edges of both metal supports 4 cross each other educated. Here is a double folding as well present as a simple attack of a metal support 4 over the edge of the other.

Nevertheless, a reversible folding box-like can also be Achieve shape of the ceiling element 1. To is then provided that the connection at an edge area hinged and opposite form-fitting is. The upper metal support 4 provides the lid and the lower metal shell 4 realized as a shell the box of such a folding box. The boxy Gestalt also goes out of the graphic representation while on a presentation of the folding technical and closing technical elements is omitted, as easily imaginable. As border areas, the considered opposite edges 17 become.

Another economically applicable means of not reopenable construction of the ceiling element. 1 may be that the upper metal support 4 and the lower metal support 4 is firmly bonded, i.e. welding technology are fixed to each other.

The ceiling elements 1 are, as already indicated, at the edge in the supporting structure of the hanging ceiling suspended.

For this purpose, the procedure is as follows: in both Embodiments are the ceiling elements 1 support sections 19 assigned. In the first embodiment is it, as already indicated, physically around the free-standing flattening 16 of the periphery of the ceiling element 1. For a square Ground plan having ceiling element 1 are possibilities an optional assignment by 90 ° going.

When subject matter according to the second embodiment are in contrast, the support portions 19 at opposite Edge areas 14 realized. They run parallel and are molded. This is preferred in the circumstances achieved by deformation. So, according to the second one Embodiment with respect to the support sections 19 applied a double layer. That stabilizes the Bracket section 19. Technically simple is the double layer achieved by edge folding. Thereby disappear also the possibly cutting burrs having Edge edges of the metal support 4 in a hiding zone between underside of the upper metal pad 4 and the top of the underlying, sound-active Layer 5. Reference is made to FIG. 10. In order to underside continuous level equality with respect to upper metal support 4 is present, the upper side of the underlapped flap lying edge area around the Dimension of a wall thickness offset upwards.

Alternately, a support portion 19 in vertical Projection formed with the lower metal support 4 and the opposite support portion 19 outside the vertical projection of the lower metal pad 4 formed. This is especially clear Fig. 9. Under the local left side bracket section 19 remains an empty throat 20. The allows the opening of the so freely trained educated Mounting portion 19 on the corresponding right-side support shoulder 3 of the mounting rail. 2

In the mentioned Fig. 9, this is cross-border Free-standing position of the support portion 19 with respect on the lower metal support 4 not available. He rather jumps clearly opposite to the edge of the relevant ceiling element 1 back. Recognizable sets the lower metal support 4 over the right end Holding portion 19 continues. The relevant Overhang is such that the support rail 2 deprived of sight is covered. To do this, he uses the projection the local support portion 19 lying right-sided Section of the sound-active layer 5 and of them supporting portion of the lower metal pad 4 as Cover strip 21 under which the support shoulders 3 forming Leg of the T-profile of the mounting rail 2. The off Fig. 8 apparent gap 22 lies to the right walking off the plane of the bridge Support rail 2. The Abdeckleise 21 fills each case the empty throat 20 of the adjacent ceiling element. 1 at least from the bottom of view blocking. The fugue 22 lies in each case laterally and deepened in the drawing right-hand leg end of the support rail. 2

Recognizable is an embodiment chosen so (see. Fig. 10) that the Rücksprungmaß x of a support portion 19, the projection dimension y of the other support portion 19 corresponds, considering one mutual distance for receiving the vertical web the Tragschniene 2. The distance may be slightly larger be as shown.

In the area of the two forming the support shoulders 3 horizontal leg of the support rail 2 is to the Submerge the sound-active layer 5 underside partial dispelled. The depth is bigger than that Thickness of thighs. This is the case with vertical projection inside the lower metal support 4 below the support portions 19 a Aushebefreiraum 23rd Der provides enough pivotal bearing play for the in Figures 9 and 11 shown operationally suitable Ejection of a ceiling element 1 from the ceiling D. Voll sufficient play is present when the Aushebefreiraum 23 in the vertical direction about half the thickness a sound-active layer 5 corresponds (this at Based on the illustrated in the drawing, approximately real thickness ratios).

Lagerbildend for the tilting movement is the left-sided Inner groove between support shoulder 3 and vertical Bridge of the mounting rail 2. Favored is the tilting by cross-rounding the end of the support portion 19 according to described edge folding.

The subject of the ceiling element 1 can also grip the bond described. The same applies here, that the adhesive 6 does not add the openings and also the relevant coating method that only Strip or islands provide the adhesive bond.

Because of the overhead tipping point, the wagging happens with respect to the left side following ceiling element disturbance, i. non-contact, like the one in Fig. 9 drawn pivoting bow 24 shows.
