Figure 1 and Figure 2 show a roof 200 of a tent with an acoustically insulated ceiling system 100 according to one embodiment of the present invention in two different configurations. Figure 3 gives more details on the acoustically insulated ceiling system 100 of figure 2, but this figure is also representative of the acoustically insulated ceiling system 100 of figure 1. Although the figures show the use of a system. ceiling 100 according to the present invention in the roof 200 of a tent, it should be noted that its use is not limited to tents, but can also be used in other types of buildings or constructions .

The roof 200 is made up of struts 201, low roof beams 202, high roof beams 203, purlins 204, roof cables 205 and scissor cables 206. In Figure 1, the ceiling system acoustically insulated ceiling 100 is disposed between two of the high roof beams 203, and in Figure 2, the acoustically insulated ceiling system 100 is disposed between two of the low roof beams 202.

The acoustically insulated ceiling system 100 includes a first channel 110, a second channel 120, and a load-bearing layer 130 suspended between the first channel.

110 and the second channel 120. In the embodiments shown, the first channel 110 and the second channel 120 are provided together on a single roof beam 202, 203, but they are used in separate acoustically insulated ceiling systems 100, arranged on opposite sides of the roof beam 202, 203. || However, it should be clear that in other embodiments, the first profile 110 and the second profile 120 can also be provided separately from each other, and that the first profile 110. In other embodiments, a single channel can also be used, for example in a circular or U-shaped configuration, provided that a carrier layer 130 can be suspended from the channel. In this case, the opposite sides of the single profile can be considered as the first profile 110 and the second profile 120.

The carrier layer 130 is used to support or support the other elements 140, 150, 160 of the acoustically insulated ceiling system 100, which will be arranged above the carrier layer 130. The carrier layer 130 may for example be a fabric covering 130. , but it should be clear that any other type of load-bearing layer 130 can be used to carry or support the other elements 140, 150, 160 of the acoustically insulated ceiling system 100.

As shown in Figure 3, the carrier layer 130 is provided with a keder

131. The carrier layer 130 is connected to the first profile 110 and to the second profile 120 by means of a keder bead 132 which is slipped into a corresponding keder guide rail 111, 121 of the first profile 110 and of the second profile 120. It is appropriate to however to specify that in other embodiments of the acoustically insulated ceiling system 100, other types of connection means can be provided on the first profile 110, the second profile 120 and / or the carrier layer 130 to connect the carrier layer 130 to the first profile 110 and to the second profile 120.

On the carrier layer 130 is disposed a lower layer 140 of high density material. In the illustrated embodiment, the bottom layer 140 is a steel plate, but it should be clear that other types of high density material suitable for sound insulation and to support the weight of other elements 150, 160 of the acoustically insulated ceiling system 100 disposed above the lower layer 140, can also be used.

The lower layer 140 has a thickness of 1.2 mm for optimum sound insulation properties of the lower layer 140 and therefore of the acoustically insulated ceiling system 100. In addition, this gives the lower layer 140 sufficient strength to withstand. other elements 150, 160 of the acoustically insulated ceiling system 100 disposed above the lower layer 140, sufficient flexibility to follow the curvature of the load-bearing layer 130 suspended between the first channel 110 and the second channel 120 so that the lower layer 140 is well supported by the carrier layer 130, and a weight low enough to be supported by the carrier layer 130. It should be clear, however, that the lower layer 140 can also be provided in other thicknesses, taking into account take into account these requirements.

The lower layer 140 extends from the first profile 110 to the second profile 120, and is embedded between the first profile 110 and the second profile 120 by means of the edges 141, 142 of the lower layer 140 bearing against the first profile 110 and the second channel 120. To this end, the edges 141, 142 of the lower layer 140 are bent upwards and slightly outwards, so that the total length of the lower layer 140 is slightly greater than the distance between the first profile 110 and the second profile 120. In this way, when the lower layer 140 is disposed between the first profile 110 and the second profile 120, a pressure connection is formed between the lower layer 140, on the one hand, and the first section 110 and the second section 120, on the other hand.

Preferably, the edges are bent outward 1.5 ° to 3.0 ° with respect to the direction of the height to ensure solid contact with the first channel 110 and the second channel 120, which may nevertheless can be removed relatively easily to dismantle the acoustically insulated ceiling system 100. The pressure connection is also advantageous to avoid noise leaks between the lower layer 140 on the one hand and the first profile 110 and the second profile 120 on the other hand .

Above the lower layer 140, an intermediate layer 160 is ... - arranged in an insulating material of low density.

The low density insulation material may for example be mineral wool, cellulose foam, fibers, particles of foam insulation material, etc.

The middle layer 160 is about 25 cm thick, which is sufficiently thicker than the lower layer 140 and the upper layer 150 discussed below.

This thickness of the intermediate layer 160 gives good sound insulation properties to the intermediate layer 160 and therefore to the acoustically insulated ceiling system 100. It should however be specified that the intermediate layer 160 can also be provided in other thicknesses, taking into account the sound insulation requirements.

Above the intermediate layer 160, an upper layer 150 is disposed in a high density material. In the illustrated embodiment, the top layer 150 is a steel plate, but it should be clear that other types of high density materials suitable for sound insulation can also be used.

The top layer 150 has a thickness of 0.8mm for optimum sound insulation properties of the top layer 150 and therefore the acoustically insulated ceiling system 100. In addition, this gives the top layer 150 sufficient flexibility to follow. the curvature of the middle layer 160, so that the top layer 150 is properly supported by the middle layer 160, and a weight low enough to be supported by the carrier layer 130. It should be clear, however, that the top layer 150 can also be provided in other thicknesses, taking these requirements into account. The top layer 150 can be provided with a thickness less than that of the bottom layer 140, since it is not necessary to have other elements on the top layer 150, so that the strength requirement is less important. . However, the lower layer 150 must be strong enough to be able to be handled and transported without damage.

The top layer 150 extends from the first profile 110 to the second profile 120, and is embedded between the first profile 110 and the second profile 120 by means of the edges 151, 152 of the top layer 150 bearing against the first profile 110 and the second channel 120. To this end, the edges 151, 152 of the top layer 150 are bent upwards and slightly outwards, so that the total length of the top layer 150 is slightly greater than the distance between the first profile 110 and the second profile 120. In this way, when the upper layer 150 is disposed between the first profile 110 and the second profile 120, a pressure connection is formed between the upper layer 150, on the one hand, and the first section 110 and the second section 120, on the other hand. Preferably, the edges are bent outward 1.5 ° to 3.0 ° with respect to the direction of the height to ensure solid contact with the first channel 110 and the second channel 120, which may nevertheless can be removed relatively easily to dismantle the acoustically insulated ceiling system 100. The pressure connection is also advantageous to avoid noise leaks between the top layer 150 on the one hand and the first profile 110 and the second profile 120 on the other hand .

When assembling the acoustically insulated ceiling system 100, the intermediate layer 130 may have been prefabricated and disposed over the lower layer 140 after the lower layer 140 has been disposed over the load-bearing layer 130, or a low density material for forming the intermediate layer 160, such as for example particles of a foam insulation material, can be disposed on the lower layer 140. Alternatively, a low density insulation material can also be injected or blown between the lower layer 140 and the top layer 150 to form the middle layer 160, provided that a closure is provided around the bottom layer 140 and the top layer 150 to maintain the low density insulation material between the bottom layer 140 and the top layer. top layer 150. In this case, the top layer 150 must be placed beforehand between the first section 110 and the second section 120 at a predetermined distance. terminated of the lower layer 140 to leave sufficient space to form the intermediate layer 130 with the desired thickness.

Another possibility consists in inserting a prefabricated intermediate layer 130 between the lower layer 140 and the upper layer 150, which have been previously arranged between the first profile 110 and the second profile 120.
