Abstract

THe ceiling has insulation panels (9) made from an asbestos-free and mineral wood-free material which fulfils the requirements for a clean space. The gaps (12) present between neighbouring insulation panels are covered by overlapping the panels or by the use of additional insulation pieces (13) placed over the gaps. The insulation panels and insulation pieces are made from a granulate formed from blown mica and compressed with the aid of a binding medium. The panels have shaped overlap sections (16) and fixing elements (17) on their long (14) and/or broad (15) sides.

Description

The invention relates to a false ceiling from side by side Ceiling panels with insulating panels arranged above them.

DE 35 14 267 A1 describes a suspended ceiling for building rooms known that formed from individual suspended ceiling components becomes. Thereby are directly on the top of the ceiling panels Insulation panels made of fireproof fiber material arranged. The insulation panels have only the height the ceiling panels. Every single ceiling tile is with one additional insulating plate covered, with no overlap the insulating plates between the ceiling elements. Additional insulation pieces on every second Insulation plate must be fastened, seal the joints of the Suspended ceiling. Therefore, the ceiling tiles are not all equal. A targeted assembly is required. The Ceiling slabs are only unsupported across the width of one Room and therefore not suitable for larger ceilings. Is too the integration of additional elements in the ceiling not easily possible because of fire protection would be weakened and secondly the weight of the built-in Element would cause the ceiling panel to bend. The introduction of different plate and mat material is very complex and expensive. It also follows the disadvantage that when the insulating plate is placed on the ceiling plate an additional inexpensive heating and Noise protection is not provided. At all joints, the for the necessary additional insulation pieces are attached to the fire retardant be, which in turn is very complex and costly is. In addition, the fiber material for the insulating plate not suitable for all room conditions.

From EP-A-0 334 106 a ceiling element is known which from a ceiling plate and a plate arranged above it consists of insulating material. The ceiling element includes one top cover of joints between two adjacent ceiling elements. The sheet of insulating material is stepped on the fold side, so that the joint to an adjacent ceiling element is stepped.

The invention has for its object a ceiling to create the type mentioned, the one hand easy to assemble and can be produced at low cost and on the other hand offers good fire, sound and heat protection and can also be used anywhere.

This object is achieved in that the Insulating plates made of an asbestos and mineral wool free, clean room conditions fulfilling material exist, and the between adjacent insulation panels by overlapping joints of these insulating plates are covered.

Through these measures, the false ceiling is also in very clean Rooms, e.g. Operating theaters or highly sensitive IT rooms, can be used. At least in one direction of expansion the ceiling is automatically overlapped the insulating plates, which has a cost-effective effect.

According to an advantageous embodiment of the invention Insulating panels made of a blown mica Granules made with a binder by pressing together. This results in a homogeneous structure of the insulating plates. The most different are when pressing together Forms can be realized, which makes an extremely cost-effective assembly is guaranteed.

The insulating plates are usually pressed together in forms in which all possible form elements are integrated can be. So own an advantageous training the invention, the insulating plates on their long sides and / or broadsides overlap shaped elements and fastening shaped elements. Due to the overlap form elements the joints between the insulating plates are covered, and over the Fastening elements can be attached to the insulating plates fix the ceiling tiles.

A covering of insulating materials between two neighboring ones Ceiling panels can be according to an advantageous embodiment of the invention obtained when the to Insulation plates attached overlap shaped elements a step fold with a protrusion in the upper step area and on the opposite side with a step fold corresponding recess formed in the upper step area are. The insulating plate thus has the shape of a Z, the exist in both the longitudinal and transverse directions can.

There are also preferably those present on the insulating plates Fastening elements from groove-shaped slots, the recessed in the step area before the overhang or the recess are. As a result, the fixing elements have always a defined position, which means that the assembly of the Insulating plate on the ceiling plate is facilitated.

Furthermore, it is preferably provided that the ceiling panels consist of a screen, the long sides and Broad sides are folded towards the ceiling, and the fold one parallel on two opposite sides aligned with the screen, above the screen arranged mounting bracket carries. This means that after inserting the insulating plate into the plate only a degree of freedom. The fixing of the insulating plate is therefore simple and inexpensive to carry out.

So that even large rooms can be provided with the ceiling tiles can, the size of the ceiling tiles the aesthetic Appearance of the entire room can be adjusted are expedient the bevels of the broad or long sides, that do not have mounting brackets, provided with rags, which have cams that are held in the ceiling Engage mounting rails and the ceiling tile moveable and snap-in, holding the rag bearing bevels leave a space between the top of the folds and the underside of the on the other folds Leave the existing mounting bracket free. So can the insulating plate is inserted laterally into the ceiling plate and gets a defined position to the inside of the Ceiling tile. Furthermore, the ceiling tile can be over the make the cams located on the tabs pivotable, with which there is a window effect for each ceiling tile.

Additional noise-reducing measures are easy to carry out, as a further advantage, an easy installation of the Insulating plate is present on the ceiling plate if after a further advantageous embodiment, the groove-shaped Slits in the insulation panels below the upper step area are embedded and the existing ones on the folds Take up the mounting bracket, the lower one Step area of the insulating plate between the top of the the ridges and the mounting bracket is inserted, and between the bottom of the insulating plate and a free space remains on the top of the screen. This air-filled space is an excellent one additional heat insulator. When using the free space for A ceiling panel is used to reduce noise, which is perforated in its screen. On the inside of the A screen is then used to attach a fleece which can also add aesthetic accents.

So that the insulating plate does not wobble on the ceiling plate and the degree of freedom still available is also determined, is preferred in the free space between the top of the screen and the bottom of the insulating plate the height filling block inserted, the width between the takes up the bevel-bearing bends and by means of at least one reaching through the insulating plate Fixing pin is attached so that the front of the block on the fold bearing the rag to the system is coming. The height of the block is chosen so that the mounting bracket on the folds on one side of the groove-shaped Slit come to rest, there is an easy Clamping the insulation plate by possibly already on the additional adjustment pin can be dispensed with. The log serves as an additional insulating piece in the area of Mounting rail.

Preferably, the front of the block on the Screen facing away from the area of the rag load-bearing fold a receiving the mounting rail Notching on, two diametrically opposite Corners of the surfaces of the block on which the mounting bracket load-bearing fold come to the plant with a Rounded radius that is at least as large as that Half the clear width between the mounting brackets bearing folds, and the length of the block is not is larger than the clear width between the front edges the mounting bracket. With this measure, the block can only after making all bends in the ceiling tile in these inserted and swiveled into the correct position become. The notch leaves enough space for the mounting rail, which are protected from direct heat is.

According to an advantageous development of the invention the ceiling panels carrying the insulating panels on the wall side placed on a wall angle profile attached to a wall, and the insulating piece preventing the thermal bridge consists of a wall connection cover with a rectangular cross-section, the placed on the insulating plate and to the Wall is pushed. It is not another additional Fastener required. The wall outlet cover can be made in strips and on site to the required Length can be shortened. Depending on the quality class of the overall ceiling the thickness of the wall connection cover is selected and used. The wall angle profile can be easily attached to the Fasten the wall, which is usually done with a screw connection he follows.

To hide both unevenness of the wall and that to facilitate subsequent color application of the walls, expediently has the wall connection profile attached to the wall a shadow gap on, through a shadow angle is formed, starting from that on the wall supported mounting flange carries a panel flange, on which the ceiling tile rests.

So that larger ceilings are provided with a false ceiling can, preferably have height-adjustable, attached to the ceiling Bracket rails a mounting rail receiving bracket that the mounting rails on their pick up top, circular arches, and their down directed leg a receptacle for the cam-bearing Form bends of the ceiling tile, the ceiling tile around the cam the tab is pivotable and in position the swiveled ceiling plate are the joints above the Fastening rail covered with insulating pieces, of which one a cross-sectionally rectangular clamping profile cover which is arranged between the mounting rails, and the other insulating piece is a U-shaped in cross section, the Clamping profile cover embracing, enclosing the mounting rail Hanger cover is that the gap between closes the clamping profile covers. This is the gap above the fastening rails is completely closed. The clamping profile cover can be easily Cut to the distance between the mounting rails getting produced. The hanger cover is called a molding with the necessary overhang over the clamping profile cover manufactured.

A high strength with the least possible material expenditure for the mounting rail is preferred if the Bracket rail has a U-shaped profile, and in the Hanger cover adapted to the profile of the holding rails Through hole is embedded. So that's the hanger cover always aligned with the ceiling tiles, and that Clamp profile cover is always above the gap above the Mounting rails held.

By using mounting rails, the Design ceiling variably, with the desired functions appropriate elements can be installed without the fire protection regulations neglected. become. In an advantageous embodiment, there is a recessed light for this purpose using brackets on the circular arches of the mounting rails, which are attached using insulating pieces is covered, one of which is the back of the Recessed luminaire cover box that is Has notches for the clamping profile covers, and the other insulating piece is the clamping profile cover that through the notches in the lamp cover box and for their part free cuts in the area of the recessed luminaire wearing. So is when using the recessed light only one additional insulation piece is required. The Clamp profile cover is in the recessed area adapted to geometric conditions.

So that the suspended ceiling meets the highest clean room conditions, are after a development of the invention Insulating plates at least on the side facing the room with a closing the surface of the insulating plate Provide coating, the glued on the insulating plates Insulating pieces are uncoated. So everyone is surfaces of the insulating plates facing the room are sealed, and the surfaces of insulating panels not facing the room and insulating pieces are uncoated, which is the advantage has that it does not warp when exposed to heat, whereby there is no thermal bridge. In addition, the insulation pieces can be manufactured even more cost-effectively. Prefers consists of a coating of the insulating plates Paper. On the one hand, the paper is inexpensive to manufacture and easily insertable into the molds, and secondly still treatable by fire retardant materials.

There is still one between the narrow sides of the insulating plates There is a thin gap that reached through the false ceiling Fire protection slightly affected. To avoid this are expediently facing each other Narrow sides of the insulation panels with a when exposed to heat provide a foaming coat of paint. The foam swells out the gap high and becomes hard due to the effect of the heat, which improves fire protection on the one hand and on the other hand the suspended ceiling stabilizes against each other.

A room 1 consists of the floor 2 side walls 3 and a ceiling arranged above 4. Through an intermediate wall 5, in which a door 6 is embedded, the room 1 of separated from another room.

With mounting rails 10 attached to the ceiling 4 a suspended ceiling 7 moved into room 1. The false ceiling 7 extends to the walls 3 and the partitions 5 and thus closes the area 11 between the false ceiling 7 and the ceiling 4 hermetically. The false ceiling 7 is made of side by side Ceiling panels 8 arranged above Insulating plates 9 formed, which are made of an asbestos and mineral wool-free, clean room material consist. The existing joints 12 between adjacent Insulating plates 9 are either by overlapping them Insulating plates 9 or by further, on the insulating plates 9 overlying insulating pieces 13 covered. All insulation pieces 13 and the insulating plates 9 consist of an inflated Mica with a suitable binder. You will be through Pressed together and can be machined. Any demoldable design of the insulating plates 9 as well as the insulating pieces 13 is conceivable. The production is done by pressing the mica together with the Binder.

In order to seal the joints 12, the insulating plates 9 are provided on their long sides 14 and / or broad sides 15 overlap shaped elements 16. There are also on these pages also fastening form elements 17.

Figures 6 and 7 show 8 attached to ceiling panels Insulating plates 9 with overlapping shaped elements 16 and fastening shaped elements 17. They are there on the long sides 14 of the insulating plates 9 attached. The overlap features 16 are by a step fold 18 with projection 19 in the upper step area and on the opposite side by a step fold 20 with a corresponding recess 21, also formed in the upper step area. The existing ones Fastening elements 17 are also in the long sides 14 of the insulating plate 9 embedded. they consist of groove-shaped slots 22 in front of the projection 19 or in front the recess 21 are recessed in the rebate 18, 20.

On the ceiling panels 8, each from a screen 23 exist, the long sides 24 and broad sides 25 are Ceiling 4 folded. The two bevels 26 on the Long sides 24 each have one parallel to the screen 23 aligned, arranged above the screen 23 Mounting bracket 27. The mounting bracket 27 is therefore oriented inwards, which makes the bowl-shaped Design of the ceiling panel 8 on the long sides 24 is narrowed.

The bevels 26 of the broad sides 25 or long sides 24 the ceiling plate 8, which do not have mounting brackets 27, are provided with rag 28. These tabs 28 have cams 29, which engage in mounting rails 30, which on the ceiling 4 are supported. About the cams 29 is Ceiling plate 8 movable and held snap. A free space 31 is between the folds bearing the tabs 28 26 and the underside 33 of the other bevels 26 existing bracket 27 provided. This freedom 31 enables the insulation panels to be inserted laterally 9 on the ceiling plate 8. So he takes the lower one Step range 35 on.

Below the upper step area 34 are in the insulating plates 9 on the long sides 14 of the groove-shaped slots 22 recessed. These slots 22 take on the folds 26 existing mounting bracket 27. Here the lower step region 35 of the insulating plate 9 between the top 32 of the bevels bearing the flaps 28 26 and the mounting bracket 27 inserted. On Free space 38 remains between the underside 36 of the insulating plate 9 and the top 37 of the screen 23 available.

In the free space 38 between the top 37 of the screen 23 and the bottom 36 of the insulating plate 9 is a Height-filling block 39 inserted. This block 39 takes the width between which the mounting bracket 27th bearing bevels 26. The block 39 is so far pushed that its front 41 on the tab 28 bearing fold 26 comes to the plant. There he will by means of a fixing pin 40 which passes through the insulating plate 9 extends into the block 39, attached. This method is carried out at both ends of the insulating plate 9. The Insulating plate 9 is thus fixed to the ceiling plate 8. The last remaining degree of freedom is thus eliminated.

The block 39 comes to rest on the folds 26 in the vicinity of which is also the mounting rail 30. There is therefore a notch on the front 41 of the block 39 42 on the side facing away from the screen 23 in the area the fold 26 carrying the flaps 28 is provided. Two diametrically opposite corners 43 of the surfaces of the Block 39, which on the mounting bracket 27 supporting Bends 26 come to rest with a radius 44 provided. This radius 44 is at least as large as that Half of the clear width between the mounting brackets 27 carrying bevels 26 so that the block 39 on the Top 37 of the ceiling plate 8 placed, turned and on the fold 26 can be pushed up. From the others Bends 26 protrude the mounting bracket 27 inwards via screen 23. The block 39 must be between the mounting brackets 27 can be inserted. Hence the length 45 of the block 39 no larger than the clear width between the front edges 46 of the mounting bracket 27.

The mounting rails 30 are always at intervals from the wall 3. For the mounting of the ceiling panels 8, which carry the insulating plates 9 are on the walls 3 Wall angle profiles 47 attached to which the ceiling panels 8 be put on. The joint 12 between the ceiling plate 8 and the wall 3 represents a thermal bridge 48 which through an insulating piece 13 is covered. With the wall side Cover, the insulating piece 13 is rectangular in cross section Wall connection cover 49. This is on the insulating plate 9 placed from above and pushed onto the wall 3.

An alternative embodiment of this shows a wall connection profile 50 with a shadow gap 51. The wall connection profile 50 is attached to the wall and has one Shadow angle 52, that of the one held on the wall Mounting flange 53 goes off and one at its end diaphragm flange 54 aligned at right angles to wall 3 wearing. On this diaphragm flange 54 is from above Cover plate 8 placed, which in turn the insulating plate 9th wearing.

The mounting rails 10 attached to the ceiling 4 are height adjustable. For this purpose, they are divided into two and consist of interlocking U-profiles. Own on her thighs they adjustment holes 62, which are the same in both rails Have grid dimension. After setting the correct required Height through the adjustment holes 62 adjustment nails 63 pushed, of which at least one to avoid the Slipping out is bent. The mounting rails 10 have on their side facing away from the ceiling 4 Bracket 55, the mounting rails 30 on their Record top circular arches 56. The bracket 55 is designed so that the mounting rails only from the side into the mounting rails 10 are inserted can. The downward going from the sheets 56 Leg 57 of the mounting rails 30 expand to a resilient receptacle 58, in the cams 29 of the folds 26, which are located on the ceiling plate 8, inserted become. To insert the ceiling panels too far To prevent 8 in the recordings 58, the Bends 26 additional stop cams 64. If the cams 29 of the tabs 28 in the receptacle 58 of the fastening rail 30 are inserted, the ceiling plate 8 around these cams 29 are pivoted, which is shown in FIG. 7 by the two-dot chain line is shown. If the ceiling panel 8 in the false ceiling 7 swung in, the cams 29 engage the folds 26 in the receptacle 58 and hold the Ceiling plate 8. Have 8 when swiveling in the ceiling plate the respective projections 19 and the recesses 21 pushed over each other and through the step fold 18 or 20 the joint 12 is sealed. Above the mounting rail 30 a step fold cannot be created. Therefore the joints 12 are covered with insulating pieces 13. One of them is a clamping profile cover with a rectangular cross section 59. This is between the mounting rails 10 arranged by pointing to the required Length is cut to length. Between the clamping profile covers 59 there is still an intermediate gap 61 which is at least as wide as the length of the legs of the Bracket rail 10. A hanger cover 60 that the Bracket rail 10 encloses and at the same time Clamp profile cover due to its U-shaped cross-section engages, closes this intermediate gap 61. By one To achieve as hermetic sealing as possible is in the hanger cover 60 existing through hole 65 for the Bracket rail 10 the profile of the bracket rail 10th customized. Therefore, the through hole 65 is U-shaped and the bracket rail 10 can with little play therein be moved.

Should room 1 be illuminated and the lighting in the false ceiling 7 are integrated, so a ceiling panel 8 through a downlight 66 replaced. The downlight 66 has the same grid dimension as the ceiling plate 8 and its front edge 71 has the same height level as the screen 23 of the ceiling panels 8. On the recessed light 66 is a Bracket 67 attached to the circular arches 56th the mounting rails 30 is placed, with which the same Height of recessed lamp 66 and screen 23 reached is. For the fire protection of the entire lower ceiling 7, the recessed light 66 is not to be lost by means of Insulating pieces 13 covered. One of the insulating pieces 13 is a enclosing the back of the recessed lamp 66 Luminaire cover box 68. The cover box 68 has notches 69 through which the clamping profile covers 59 run, which the joints 12 above the mounting rails Cover 30. So that the clamping profile covers 59 in one piece they can continue to be carried in the area of the recessed luminaire 66 free cuts 70 that the Enclose housing of recessed light 66.

At least on the side facing the room 1 Surfaces 72 of the insulating plates have a coating. This coating closes the surface 72 of the Insulating plate 9, whereby the compressed mica is not can crumble. The placed on the insulating plates 9 Insulating pieces 13 have no coating, which makes them heat, even one-sided heat, do not warp and there is no thermal bridge. The Coating usually consists of a paper that is for fire protection is treated with appropriate means.

Between the individual insulating plates 9 and also the insulating pieces 13 are still thin joints 12, namely even if the parts touch each other. This Narrow sides 73, which are also in the corresponding step folds 18, 20 are present, are provided with a coat of paint Exposure to heat creates a foam. This foam closes the joint 12 is tight and hardens, causing the false ceiling 7 receives internal stress and becomes self-supporting.
