Description

[0016] The present invention is further elucidated on the basis of the following figures which show preferred embodiments of the partition wall according to the present invention and are not intended to limit the scope of protection of the invention in any way, wherein:

[0017] FIG. 1 is a cross-sectional side view of an embodiment of the partition wall according to the invention; and

[0018] FIG. 2 is a cross-sectional top view of an embodiment of the partition wall according to the invention.

[0019] FIGS. 1 and 2 show respectively a cross-sectional side view and top view of a partition wall 100 according to the invention for partitioning a space into a first space 200 and a second space 300. Partition wall 100 is placed between a floor 400 and a ceiling 500 and against a wall 600, and consists inter alia of three wall panels 101, 102 and 103, which are mounted on vertical clamping posts 104, 105 and 106. In the shown embodiment wall panels 101, 102 and 103 are steel wall panels, each with a steel outer cladding with a thickness of about 0.8 mm Wall panels 101, 102 and 103 are arranged on clamping posts 104, 105 and 106 such that wall panel 101 is arranged only on the vertical clamping posts 104 and 106, while wall panels 102 and 103 are not arranged on the vertical clamping posts 104 and 106 and share clamping post 105 in a structural sense. In this way wall panel 101 is disposed structurally clear of wall panels 102 and 103, whereby wall panel 101 is acoustically uncoupled from wall panels 102 and 103. Sound produced in the first space 200 and/or the second space 300 is hereby at least substantially wholly absorbed by partition wall 100. More specifically, the partition wall 100 according to FIGS. 1 and 2 has a weighted sound reduction index (R.sub.w value) of at least 62 dB in a measurement in accordance with ISO standard 717-1:2013.

[0020] Partition wall 100 further comprises a horizontal lower post 107, mounted on floor 400, of steel plate with a thickness of about 1.5 mm and a horizontal upper post 108, mounted on ceiling 500, of steel plate with a thickness of about 1.5 mm, wherein wall panels 101, 102 and 103 are arranged between upper post 108 and lower post 107. A strip of resilient material 109 is further arranged between floor 400 and lower post 107 and between ceiling 500 and upper post 108. Strip 109 of resilient material ensures that gaps between floor 400 and lower post 107 and between ceiling 500 and upper post 108 are sealed, which increases the weighted sound reduction index (R.sub.w value) in accordance with ISO 717-1:2013.

[0021] Partition wall 100 further comprises a connecting profile 110 between lower post 107 and wall panels 101, 102 and 103. A strip of resilient material 109 is also arranged between lower post 107, connecting profile 110 and wall panels 101, 102 and 103 as well as between upper post 108 and wall panels 101, 102 and 103. The distance between connecting profile 110 and lower post 107 is herein in particular adjustable. This makes it easily possible to compensate for unevenness in floor 400, while the height of lower post 107 can be made as small as possible. Such a strip 109 of resilient material between lower post 107, connecting profile 110 and wall panels 101, 102 and 103 as well as between upper post 108 and wall panels 101, 102 and 103 likewise ensures that gaps between lower post 107, connecting profile 110 and wall panels 101, 102 and 103 as well as between upper post 108 and wall panels 101, 102 and 103 are sealed, which increases the weighted sound reduction index (R.sub.w value) in accordance with ISO 717-1:2013.

[0022] Wall panels 101, 102 and 103 further comprise an outer layer 111, for instance of metal, and an inner layer 112 of gypsum fibre board. A particular advantage of such gypsum fibre boards 112 is that they have excellent sound-insulating properties and therefore contribute to the sound-absorbing capacity of partition wall 100. Lower post 107 and upper post 108 are also provided with gypsum fibre material 112. This also prevents transmission of sound vibrations via, successively, floor 400 and lower post 107 and ceiling 500 and upper post 108 in efficient manner.

[0023] In addition to the above stated sound damping measures, a layer of rock wool 113 with a thickness of about 60 mm is arranged between wall panel 101 and wall panels 102, 103. In addition to the above stated measures, rock wool 113 provides for a substantial sound reduction, which increases the weighted sound reduction index (R.sub.w value) in accordance with ISO 717-1:2013.

[0024] Finally, sound-damping spacers are placed between inter alia wall panel 101 and clamping posts 104 and 106 as well as between wall panels 102, 103 and clamping post 105, such that the transmission of vibrations from said wall panels 101-103 to the respective clamping posts 104-106 is minimized.

[0025] The present invention is not limited to the shown embodiments but also extends to other embodiments falling within the scope of protection of the appended claims.
