Ceiling element according to claim 1, characterized and the sound-absorbing material marked, d <o> the lateral edges of the ao the bottom of the box up to the level of the supports Boxes (23) of adjacent ceiling elements are covered, while a heavy plate inside the the narrowing through the supports (25 and 26) the box rests on the supports and from the top in the area of their visible sides close to each other - part of the side edges of the box are fixed to the side, is laid. 25 An advantageous embodiment of the ceiling elements according to the invention is that the lateral edges of the chest; adjacent ceiling The invention relates to a sound-absorbing and elements downstream of the constriction by the supports in the sound-insulating floor element with a sound area of their visual-side closely adjacent to each other, absorbing material-containing box, WEL 30 adjacent to the correct arrangement Deckencher from a soundproofed rooms ^<r fcnden plate is covered. elements in relation to each other to facilitate the There are already such ceiling elements known to improve sound insulation and a precisely level, each consisting of a box, to realize a grain ceiling surface,
combination of sound-absorbing material, such as Glass wool, and a plate made of heavy material, explain the ceiling element according to the invention Contains plaster, which covers the sound insulation. The F i g. 1 and 2 each show a schematic diagram. see section through embodiments of the These boxes, which are attached to the ceiling of a room of the ceiling element according to the invention,
are hung in such a way that they form a false ceiling. Each ceiling element consists of a few branches 16 but only have to be removable for the purpose 40 or 23 made of sheet metal, which has holes in its bottom be that the maintenance or repairs to the 17 and 24 respectively. The side edges of this "Different lines for electricity, water, gas of Kazan 16 and 23 are shaped so that they are inner can be made in the between support 18 and 19 or 25 and 26 for a heavy Ceiling and false ceiling formed space - plate 20. For example, a plasterboard, form, are arranged. 45 The heavy trapped between these The known arrangements are difficult from the plate 20 or 27 and the bottom of the box 16 acceptable, since either the sound-insulating plate or 23 is formed with a sound-absorbing is arranged on the top of the box, and renden material 21, such as glass wool, filled. Everyone in this case, one does not see after assembly. Box 16 or 23 points on one of its side on whether this plate has a bend 22 or 28 just above the box at 5 ° edges, which the is ordered or the heavy plate below the corresponding edge strip of the adjacent ceiling , j box is arranged and in this case one is supposed to include elements. j always forced on the one hand to cover on the one hand, the ceiling element according to the invention is easy to provide a loop on the top of this box, removable and contains all for sound insulation and on the other hand is the necessary components under the box, such as the sound-absorbing plate heavy material in the suspended material 21 and the heavy plate 20.

Improvement of the correct arrangement of several In the ceiling elements known from DE-GM 18 34 205 side by side and the sound arrangement, the plate made of heavy material 60 absorption is realized a flat ceiling surface. The fastened under the box and contains the absorbent supports 25 and 26 for the heavy plates 27 are generating material, but if one assumes that these are formed by folding so that the side edges of the heavy plates must abut each other without gaps, the boxes 23 of adjacent decking elements in order to achieve an optimal effect, one is close to each other on their visible sides,
It is compulsory to fasten these plates to the 65 slight bevels 29 at the corners of the Ka box after they have been pushed, by suspending them by means of fastening 23, height differences of adjacent fastening screws. The assembly of these plates compensate for the deck elements.
