Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0059] Advantages of the present invention will be readily appreciated as the same becomes better understood by reference to the following detailed description when considered in connection with the accompanying drawings wherein:

[0060] FIG. 1: a schematic representation of a drywall in a horizontal section;

[0061] FIG. 2: a detailed representation of the drywall from FIG. 1 in a horizontal section;

[0062] FIG. 3: measurement of a normalized flanking level difference of a drywall with partial shielding by means of a facing shell and a drywall without partial shielding by means of a facing shell, and

[0063] FIG. 4: normalized flanking level difference of the drywall with partial shielding from FIG. 3 relative to the normalized flanking level difference of the drywall from FIG. 3 without partial shielding by means of a facing shell.

:DETAILED DESCRIPTION

[0064] FIGS. 1 and 2 show a drywall 1 with a first wall section 2 and a second wall section 3. The first all section 2 has first stud elements 4 on which a first paneling 5 is arranged on a room side R, The second wall section 3 has second stud elements 6 on which a second paneling 7 is arranged on the room side R.

[0065] In the embodiment shown, the drywall I is connected to a further building element 10. The further building element 10 is a wall running at right angles to the drywall 1 in the embodiment shown. The wall can be a solid wall or also a drywall,

[0066] FIGS. 1 and 2 also show that in the first wall section 2, there is a first regular center distance A between the first stud elements 4 which is greater than a second regular center distance C between the second stud elements 6 of the second wall section 3. For example, the center distance A can be 625 mm and the center distance C 312.5 mm.

[0067] The smaller center distance C in the area of the second wall section 2 has several advantages. On the one hand, the reduced center distance between the second stud elements 4 increases the rigidity of the second wall section 3 and thus reduces the flanking sound conductivity in this area, This is advantageous because the highest sound radiation from the flanking sound propagation is given in this area. On the other hand, the smaller center distance C improves the static of this area. This also makes it possible to compensate for the generally poorer static properties of narrower second stud elements 6 of the second wall section 3 (compared to the wider first stud elements 4 of the first wall section 2).

[0068] The drywall shown also has a facing shell 13, which is arranged in the area of the second wall section 3. The facing shell 13 comprises the third stud elements 14 as well as a facing shell paneling 15 attached thereto.

[0069] As shown, the second paneling 7 can be offset from the first paneling 5, so that the drywall 1 forms a recess 8 in the area of the second wall section 3 on the room side R.

[0070] The facing shell 13 is arranged in the recess 8. The facing shell 13 closes off the recess 8 on the room side so that the facing shell paneling 15 is flush with the first paneling 5. In this way, the first and second wall sections 2, 3 produce a continuous and stepless surface on the room side R. Contrary to what is shown, the facing shell 13 can also be provided without a recess being formed in the second wall section. In this case, the facing shell 13 protrudes towards the room side R relative to the first wall section 2.

[0071] FIGS. 1 and 2 also show that the second wall section 3 is arranged in a corner area. The second wall section 3 abuts the further building element 10. The flanking sound propagation is highest in corner areas because it decreases with the distance from the excitation point, i.e. the entry point of the sound waves from the sound source into the. drywall 1, Therefore, additional insulation in this area, at the transition between one room and the other, is particularly effective.

[0072] The elongated first stud elements 4 have a first width B in a direction perpendicular to their longitudinal axis. The elongated second stud elements 6 have a second width D in a direction perpendicular to their longitudinal axis. The first width B is larger than the second width D. The stud elements 4, 6 are arranged flush on the side opposite to the room side R, while the recess 8 is formed on the room side R.

[0073] In the embodiment shown, the drywall 1 is designed as a partition wall which separates a first room I I from a second room 12. However, the drywall 1, as a flanking wall, is also relevant for sound transmission between rooms 1 1 and 30, which are separated by the building element 10.

[0074] In the embodiment shown, the drywall 1 is planked on both sides. As shown, a paneling 9 is provided on the side of the drywall 1 facing away from the room side R. Due to the aligned arrangement of the first and second stud elements 4, 6, the paneling 9 is formed in one plane and without offset.

[0075] While for the first paneling 5, the second paneling 7 and the paneling 9 a single-layer design is shown in the figures, a two-layer or multi-layer design of the paneling can be provided instead. Single-layer and multi-layer paneling can also be combined in the different wall sections. The paneling is typically composed of panels arranged next to and/or on top of each other. The panels can be formed in particular as gypsum plaster boards, gypsum fiber boards or fiber cement boards. Wall boards made of other materials are also possible.

[0076] In the example shown, the first stud elements 4 are formed as first studs, each comprising a first stud web 16 and two first stud flanges 17 arranged on the first stud web 16. The first stud webs 16 have the width 13. The second stud elements 6 are formed as second studs, each with a second stud web 18 and two second stud flanges 19 arranged on the stud web 18. The second stud webs 18 have the width D. The first stud flanges 17 are perpendicular to the first stud web 16 and the second stud flanges 19 are perpendicular to the second stud web 18. The third stud elements 14 are formed as third studs which each have a third stud web 20 and two third stud flanges 21 which are arranged on the third stud web 20. The third stud flanges 21 are perpendicular to the third stud web 20. In the exemplary embodiment shown, the first, second and third studs are each formed as C-studs.

[0077] The first, second and third studs are each formed as metal studs. The first, second and third studs can be formed as simple dry construction studs and have a material thickness between 0.4 mm and 1 mm. The first, second and/or third studs can, however, also be designed as light-gauge studs and have a material thickness of the metal sheet between 1 mm and 5 mm.

[0078] The first and second stud elements 4, 6 are arranged in such a way that the first and second stud webs 16, 18 are arranged parallel to each other. The first and second stud flanges 17, 19 can point in the same direction, starting from the first and second stud web 16, 18 with their stud flanges 17, 19, respectively. The first paneling 5 is arranged on the first stud flanges 17, the second paneling 7 on the second stud flanges 19.

[0079] The third stud elements 14 are arranged in front of the second paneling 7 in the recess 8. In this case, the third stud webs 20 are arranged perpendicular to the first and second stud webs 16, 18. The facing shell paneling 15 is arranged on the third stud webs 20. The third stud flanges 21 extend from the third stud webs 20 toward the second paneling 7. In the embodiment shown, the third stud elements 14 are arranged freestanding and do not abut the second paneling 7.

[0080] In addition, FIG. 2 shows that the first paneling 5 is connected to the first stud flanges 17 with fastening means 22. The second paneling 7 is connected to the second stud flanges 19 by further fastening means 22. The facing shell paneling 15 is connected to the third stud flanges 20 by further fastening means 22. In the embodiment shown, fastening means 22 are formed as screws which extend through the respective paneling into the first stud flange 17, the second stud flange 19 or the third stud web 20. Other types of fastening, in particular with staples, nails and/or adhesives, are also possible.

[0081] FIG. 2 also schematically shows that the drywall can be provided with insulating material 23. The insulating material 23 is arranged in the first wall section 2 between the first stud elements 4 and in the second wall section 3 between the second stud elements 6. Insulation material 23 can also be provided in the. recess 8 in the space formed between the facing shell paneling 15 and the second paneling 7.

[0082] FIG. 3 shows measurements of the normalized flanking level difference Dn,f in decibels performed in acoustic testing facilities according to DIN EN ISO 10848-3 (as valid on 1 Nov. 2019). Shown here is the measurement on a room-high angular arrangement in which a partition wall and a flanking wall form a corner area.

[0083] In the measured example, the flanking wall was created with a CW-stud with the following dimensions: stud web width: 147 mm; stud flange width: 50 mm; material thickness: 1.5 mm. The center distance was 625 mm. The flanking wall is planked with 15 mm thick Knauf Diamant X gypsum plasterboards. The flanking wall is provided with 150 mm thick mineral wool insulation.

[0084] The partition wall 10 arranged perpendicular to the flanking wall was created in the measured example with a CW-stud with the following dimensions: stud web width: 97 mm; stud flange width: 50 mm; material thickness: 1.5 mm. The center distance was 62.5 mm. The partition wall is planked with 15 mm thick Knauf Diamant X gypsum plasterboards. The partition wall is provided with 80 mm thick insulation material.

[0085] The T-joint between the flanking wall and the partition wall is designed as an angular screw joint.

[0086] The measuring line marked with circles refers to the aforementioned wall without facing shell, while the measuring line marked with triangles refers to the wall with facing shell. The horizontal width of the facing shell is 1.2 m. The depth of the facing shell is 0.12 m. The facing shell is arranged room-high in the corner area in front of the flanking wall.

[0087] The shown measurement results show that the solution with facing shell results in a considerable improvement of sound insulation. The measurement results show that a considerable improvement is achieved over almost the entire frequency range. FIG. 3 additionally also shows the weighted normalized flanking level difference Dn,f,w for the solution without facing shell. It is determined according to DIN EN ISO 10848-3 and amounts to 53 dB.

[0088] Finally, for the measurement results shown in FIG. 3, FIG. 4 shows the normalized flanking level difference Dn,f in decibels for the wall with facing shell in relation to the design without facing shell. Here, it can be clearly seen that in the range from about 100 to 4,000 Hz, the normalized flanking level difference Dn,f is more than 5 dB higher. In the range up to about 500 Hz, the difference is even more pronounced and lies at the peak at more than 10 dB.
