Self-supporting ceiling element for preferably Underfloor systems

The invention relates to a self-supporting ceiling element for preferably suspended ceiling systems, which depending on the acoustic _t; Requirements of the room can be laid variably.

ψ ' It is known that classrooms, conference rooms etc.

ttl ¹ : have drawn acoustic properties when over hard

ι Ceilings and the necessary sound absorption on the \ '■■ walls or even better on the floor, for example by a

Carpet covering ,, ■; follows. On the other hand, there is a large one ! Number of rooms the condition in the foreground that un- ; desired interfering noise should be largely absorbed by this is for example in corridors of schools, universities or

other large buildings are the case. To the requirement of a; It is essential to optimally fulfill extensive sound absorption In these rooms it is advisable to design not only the floor and the walls, but also the ceilings to be sound-absorbing.

I! Ij

:; ; In well-known ones, for example in new university buildings i! Suspended ceiling systems used are generally i'i ι; sound-absorbing ceiling elements used for all rooms. ; | ; This has the consequence that even in the rooms in which a

■ '' good and undisturbed sound propagation is desired a considerable part of the sound is absorbed.

The object of the invention is to provide a ceiling element for front |; preferably to create variable suspended ceiling systems in which

i |; ; Use the blankets in an extremely easy way to j ^! the acoustic requirements of the respective room

: can be fitted.

! According to the invention this object is achieved in that

ι; an outer surface of the ceiling element as a sound reflector ü 'acting hard layer and the opposite outer surface ι is designed as a sound absorption layer and that brackets are provided on the element, depending on the desired acoustic conditions of the room, a relocation of the element to form a sound reflector ceiling or a sound cover; ' Allow sorption blanket.

j An advantageous development of the invention

■ ceiling element is characterized by the fact that the sound

l Absorbent Schleht has a large number of holes and

j is optionally provided with a fiber layer.

Particularly advantageous reflection properties result, j | if the layer acting as a sound reflector is hard and even

f is formed.

|| The particular advantage of the ceiling element according to the invention

can be seen in particular in the fact that the respective rooms

their size and shape can be adapted to special requirements not only in terms, but also that .Your acoustic properties can there be influenced by the choice of installation of the ceiling panels Due to the functional support of these elements further the possibility of flipping the elements, the acoustics in this Rooms to change.

In the following an embodiment of the invention is explained in more detail with reference to the drawing. Show it:

1 shows a ceiling element according to the invention in a perspective illustration;

2 shows a spring element for holding the ceiling element according to Fig. 1;

Fig. 3 shows a carrier of the ceiling system in which the ceiling element according to Fig.l is suspended.

The ceiling element 1 shown in Fig. 1 is made in one piece from a unitary sound-absorbing. Material made. Its one outer surface 2, which is upper in the drawing, is designed as a sound absorption layer and has a multiplicity of holes J. Reinforcements 4 can be provided in the interior of the Deokenelementes which, however, are not absolutely necessary with an appropriate selection of the materials. The lower surface 5 in the drawing acts as a sound reflector. It is hard and ben, cv. ·; '· "■.'. '. ^: ¹ - ..

As can be seen from the drawing, are provided in the edges β of the element Sohlj.'pz «7, in which a spring bar supported, Jedey end of this spring rod is once on the side 9 and once naoii above 10 angled and bent to form a loop 11 to achieve an improved spring effect.

¹¹ ι

To mount the ceiling, the spring bar 8 is in the slot! 'of the ceiling element inserted so that its doubly curved I j end hook protrudes over the upper surface of the element. This protruding hook part then engages in slots 12 of a carrier 13 of the ceiling structure. By simple Longitudinal displacement of the spring bar with the help of a screwdriver inserted in the edge gap between the elements

the element can be fixed.

j ι i As can be seen from Fig. 1, an improved insulation

\ effecting ceilings can be achieved by using an insulating mat
