Description

FIELD OF THE INVENTION

[0001] The invention relates to a partition wall, particularly to a sound insulating partition wall.BACKGROUND OF THE INVENTION

[0002] One of the problems with the partition walls is that they must be build on-site. Demolition without damaging the partition walls is difficult and reassembling reveals damages caused by the demolition. Thus, reuse is challenging.

[0003] Another problem relates to sound insulation, i.e. the partition walls do not adequately insulate sound.BRIEF DESCRIPTION OF THE INVENTION

[0004] An object of the present invention is to provide a partition wall that overcomes the above problems. The objects of the invention are achieved by the partition wall which is characterized by what is stated in the independent claims. The preferred embodiments of the invention are disclosed in the dependent claims.

[0005] The invention is based on the idea of building the partition wall from elements.

[0006] An advantage of the partition wall is that it can be reused. Another advantage is that the partition wall is sound-insulating. Still another advantage is that the partition wall may be thinner than the partition walls of the prior art but may have the same sound insulation ability. From a builder's point of view, the basic principle of the partition wall is always the same although details may change.

[0007] The partition wall is described in this text in an erected position.

[0008] The partition wall comprises a base on which elements stand side by side. The base may comprise a runner on a floor, height adjustment plates on top of the runner and two mirror symmetric L-shaped profiles on top of the height adjustment plates in such a manner that one branch of the L-shaped profile is on top of the height adjustment plates and another branch in on the side of the height adjustment plate. The height adjustment plates form levelling means that guarantee that a foundation on which the elements are assembled is horizontally straight. The runner may comprise channels for insulating sound.

[0009] There may be a guiding member, such as a rail, between the L-shaped profiles on top of the height adjustment plates. The guiding member centres the elements on the base.

[0010] The partition wall comprises blind elements, i.e. elements without openings, such as window or door openings. The partition wall may comprise window and door elements. The partition wall may also comprise junction elements at a crossing of two or more walls. The junction elements may be hollow metallic pillars that are covered with a suitable surface material. The partition wall may comprise elements that extend from the base to a ceiling, or elements on top of each other so that their total height extends from the base to the ceiling.

[0011] Each blind element has a front part and a back part. There is a space having a thickness between the front part and the back part. The front part and the back part are largely separated from each other, i.e. structures that may convey sound are minimized. The space may be empty, or it may be loaded at least partially with a sound insulation material. The sound insulation material dampens acoustic reflection. The space may also be utilized e.g. by leading electric wires through the space.

[0012] The front part comprises a front plate that has a first outer face and a first inner face. The first outer face is an outwards visible surface. The front plate is usually a rectangular plate having two horizontal sides and two vertical sides. The front part comprises first end plates on both vertical sides of the front plate. The first end plates extend from the first inner face towards the second inner face.

[0013] The back part comprises a back plate that has a second outer face and a second inner face. The second outer face is an outwards visible surface. The back plate is usually a rectangular plate having two horizontal sides and two vertical sides. The back part comprises second end plates on both vertical sides of the back plate. The second end plates extend from the second inner face towards the first inner face.

[0014] Each of the first and second end plates have widths that are less than the thickness of the space. The first end plate and the second end plate next to each other overlap without touching each other. As the first and second end plates overlap and have widths that are less than the thickness of the space there is sound insulation between the front part and the back part, i.e. the front part and back part are substantially separated from each other. If more insulation material is required in the space it is adequate to increase the thickness of the space, i.e. distance the front and back plates from each other and choose wider first and second end plates.

[0015] The front and back plate may be made of any material suitable for a partition wall. The front and back plate may be of gypsum board, chipboard, or medium density fiberboard (MDF), for example. The front and back plate may be one-layer structure, or they may have several layers one above the other. Naturally, sound insulation properties should be taken into consideration when selecting materials of the front and back plates.

[0016] The first inner side of the front plate and the second inner side of the back plate may comprise profiles that are for assembling the first and second end plates. The profiles may extend on both vertical sides of the front and back plate preferably from top to bottom. The profiles have seats that receive the first and second end plates. The profiles may be metallic profiles, such as aluminium profiles. The metallic profiles guarantee a tight and more accurate structure for the partition wall.

[0017] Between the first and the second end plates there is an insulation that dampens structure-born sound. The insulation is preferably made of a porous material, such as rock wool or a porous insulation of polyester. The insulation may extend from the bottom to the top.

[0018] The partition wall may comprise at least one window element. At the window element the base may comprise a runner on a floor, height adjustment plates on the runner and side plates provided with L-shaped metallic profiles.

[0019] The structure of the partition wall is such that a contact area between adjacent parts is minimized e.g. by protrusions or air gaps. Contact points are usually provided with seals in order to dampen sound.BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In the following the invention will be described in greater detail by means of preferred embodiments with reference to the accompanying drawings, in which Figure 1 shows a horizontal cross-section of a partition wall; Figures 2 and 3 show side views of a partition wall; Figure 4 shows an enlarged side view of the base; Figure 5 shows a base and an element in a perspective view; Figure 6 shows a perspective view of a top of a blind element; Figures 7 and 8 show side views of a partition wall; Figure 9 shows an enlarged side view of the upper part of the window; Figure 10 shows an enlarged side view of the lower part of the window; Figure 11 shows a perspective view at the window during assembly; Figure 12 shows a horizontal cross-section of the assembly of the window; Fig. 13 shows a horizontal cross-section how a blind element may be joined to a junction element. DETAILED DESCRIPTION OF THE INVENTION

[0021] Figure 1 shows a horizontal cross-section of a partition wall 1 comprising blind elements 2. Each blind element 2 has a front part 3 and a back part 4 and a space 5 having a thickness t between the front part 3 and the back part 4. The front part 3 comprises a front plate 6 having a first inner face 7 and the back part 4 comprises a back plate 8 having a second inner face 9. The front part 3 comprises first end plates 10 on both vertical sides of the front plate 6. The back part 4 comprises second end plates 11 on both vertical sides of the back plate 8. The first end plates 10 extend from the first inner face 7 towards the second inner face 9 and the second end plates 11 extend from the second inner face 9 towards the first inner face 7. Each of the first and second end plates 10, 11 have widths that are less than the thickness of the space t and the first end plate 10 and the second end plate 11 next to each other overlap without touching each other (see the first and second end plates 10, 11 in the middle of Fig. 1). In other words, both the first end plate 10 and the second end plate 11 have a width w that exceeds the half of the thickness of the space 5. There is insulation material 12 between the first and second end plates 10, 11 belonging to the same blind element 2.

[0022] The first inner face 7 of the front plate 6 and the second inner face 9 of the back plate 8 may comprise profiles 13 that are for assembling the first and second end plates 10, 11. The profiles 13 may extend on both vertical sides of the front and back plates 6, 8 preferably from top to bottom. The profiles 13 have seats 14 that receive the first and second end plates 10, 11. Against the outer seat 14 of the blind element 2 there is a gasket 17. An air gap 16 is between the front or back plate 6, 8 and the respective seats 14. At a joint of two blind elements 2 there are grooves in the front plate 6 and the back plate 8 in order to attach the profiles 13 to the grooves. As the profiles are attached to the grooves a firm joint is formed. The profiles 13 may be fastened to the front and back plates 6, 8 by screws.

[0023] Figs. 2 and 3 show side views of a partition wall 1 comprising a blind element 2 and a base 15. Fig. 4 shows an enlarged side view of the base 15. Fig. 5 shows a perspective view of the blind element 2 and the base 15 at the blind element 2.

[0024] The blind element 2 of Figs. 2 - 4 may have the same structure as the blind elements 2 in figure 1. The blind element 2 comprises a front plate 6 and a back plate 8. There are first end plates 10 on the vertical side of the front plate 6 and a second end plate 11 on the vertical side of the back plate 8. The first end plate 10 extends from the first inner face 7 towards the second inner face 9 and the second end plates 11 extend from the second inner face 9 towards the first inner face 7 as shown in Fig. 1.

[0025] The base 15 at the blind element 2 comprises a runner 18 against a floor. There may be a sound-insulating seal 23 between the floor and the runner 18. The runner 18 comprises channels 19 for enhancing sound proofing. On top of the runner 18 there are height adjustment plates 20 whose height may vary from 0.5 mm to 10 mm. In practice, a laser beam is used to find a horizontal plane and the height adjustment plates are placed at intervals on the runner 18 in such a manner that all top surfaces of the height adjustment plates are on the same plane.

[0026] Two mirror-symmetric L-shaped profiles 21 are assembled on top of the height adjustment plates 20 in such a manner that one branch of the L-shaped profile is on top of the height adjustment plates and another branch in on the side of the height adjustment plate. The top surfaces of the L-shaped profiles 21 are horizontal, i.e. they form a straight plane to erect the elements of the partition wall 1. There may be a longitudinal rail 22 between the L-shaped profiles for guiding the elements.

[0027] Fig. 6 shows a perspective view of the top of the blind element 2 of Fig. 1 when the top plate is removed. A joint between two blind elements 2 is formed by flanges 24 and a bolt 25. The flanges 24 are fastened to the top plate (not shown in Fig. 6). The distance between the flanges 24 is constant, i.e. screwing the bolt 25 does not have effect on the distance and therefore, dimensional errors are avoided. The same arrangement is also in the lower part of the element 2 as can be seen e.g. in Figs. 2 and 3.

[0028] Figs. 7 and 8 show side views of a partition wall 1 comprising a window element 26 and a base 15 at the window. Fig. 7 shows the partition wall 1 without the height adjusting plates 20 and Fig. 8 shows the partition wall 1 with the height adjustment plates 20. Fig. 9 shows an enlarged side view of the upper part of the window. Fig. 10 shows an enlarged side view of the lower part of the window. Fig. 11 shows a perspective view at the window during assembly.

[0029] The partition wall 1 may comprise the window element 26. The window element 26 comprises a window 27 and a solid part 28 above the window. The solid part 28 may be similar to the blind element 2 but lower. In some cases the flange 24 and the bolt 24 misses from the lower part of the solid part 28.

[0030] The base 15 at the window element 26 comprises a runner 18 on a floor. There may be a sound-insulating seal 23 between the floor and the runner 18. The runner 18 comprises channels 19 for enhancing sound proofing.

[0031] The base 15 comprises height adjustment plates 20 on the runner 18 and side plates 29 provided with L-shaped metallic profiles 30. The L-shaped metallic profiles 30 comprise protrusions that touch the runner 18, i.e. the areas that touch each other are minimized.

[0032] The window 27 is assembled by using a first batten 31 and a second batten 32. The window 27 is placed in a groove in the first batten 31 and fastened to its place by the second batten 32. Both sides of the window 27 are provided with gaskets 33, 34.

[0033] Figure 12 shows a horizontal cross-section how the window 27 is fastened to an adjacent structure, such as an adjacent junction element 35 covered with a suitable surface material. The vertical sides of the window 27 are assembled between a third batten 36 and a fourth batten 37. The window 27 is placed in a groove in the third batten 36 and fastened to its place by the fourth batten 37. Both sides of the window 27 are provided with gaskets 38, 39.

[0034] The gaskets 33, 34 in Figs. 9 and 10 and the gaskets 38, 39 in Fig. 12 preferably have a cross-section that have claw-like protrusions. Those kind of protrusions assist to form more even appearance compared to usual fastenings based on iron nails. The window assembly requires only a few iron nails 40 as shown in Fig. 12.

[0035] Fig. 13 shows a horizontal cross-section how a blind element 2 may be joined to a junction element 35. The same assembly may be used when the partition wall 1 is joined to an existing wall. A connection profile 41 is attached to the junction element 35 and the profiles 13 are attached to the connection profile 41.

[0036] It will be obvious to a person skilled in the art that, as the technology advances, the inventive concept can be implemented in various ways. The invention and its embodiments are not limited to the examples described above but may vary within the scope of the claims.
