Description

False wall

The invention relates to a false wall that is to be placed at a distance from a rear wall, in particular in areas containing sanitary equipment, for example toilets and bathrooms. False walls of this type are often used as a replacement for tiled walls. They can also be used as a replacement for brick walls.

DE 100 01 517 has disclosed a false wall of this type. The known false wall comprises a frame composed of metal profiles. In particular, the known frame comprises a metal base profile of C-shaped cross section, which base profile is placed on a floor at a distance from the rear wall, a metal wall profile of C-shaped cross section, which wall profile is arranged substantially horizontally on a rear wall, and a plurality of upright profiles which extend substantially vertically upwards from the base profile and at a top end thereof are connected to the wall profile by means of a connecting part. Furthermore, the false wall comprises one or more covering panels having a visible side and a back side. The back side of the covering panel is connected to the frame.

One aspect of the invention relates to a false wall according to claim 1.

According to this aspect of the invention, the covering panels are provided on the back side with one or more threaded rods extending in the direction of the rear wall, wherein each of the upright profiles has attached to it a clamping plate with an opening for the threaded rod to be fitted through and tightened by means of a nut or the like. One advantage of this measure is that the covering panel is easy to align and clamp in place with respect to the frame, so that the adjacently positioned covering panels can form a substantially flat wall surface and are securely attached to the frame.

Another aspect of the invention relates to a false wall according to claim 2._

According to this aspect, beneath the base profile of the frame is arranged an underlay profile, which is preferably made from plastic, rubber or for example from metal that has been covered with rubber or plastic. The underlay profile results in improved sealing with respect to moisture. Furthermore, the underlay profile offers the possibility of compensating for irregularities in the floor. The underlay profile also limits the transmission of sound between the false wall and the floor.

Preferably, the underlay profile comprises a base strip with a longitudinal wall that extends upwards therefrom, as well as a front longitudinal wall which, together with the base strip, form a groove in which the underside of the covering panel can be placed. The groove makes it easy to position the covering panels.

Yet another aspect of the invention relates to a false wall according to claim 12.

According to this aspect, the joints between the covering panels are located at the position of the upright profiles. A joint profile is arranged between the covering panels. The joint profile comprises a flexible joint piece which, in the assembled state, is located between two opposite side edges of two adjacent covering panels. Furthermore, the joint profile comprises a back strip which is connected to an end of the joint piece that in the assembled state is located on the back side of the covering panels. In the assembled state, the back strip is located between the back side of at least one of the said adjacent covering panels and the upright profile, with the result that the joint profile is fixed with respect to the panels and the frame. Furthermore, this makes it possible to damp vibrations between the upright profiles of the frame and the covering panels. To improve the vibration-damping action, if appropriate grooves may be arranged on one or both sides of the back strip. The joint profile also comprises sealing ribs which are connected to that end of the joint piece which in the assembled state is located on the visible side and extend in the transverse direction therefrom. This ensures that the edges of the covering panels are covered on the front side. Furthermore, the joint profile provides good sealing with respect to moisture, thereby eliminating the need to use, for example, a silicone cement.

The invention will be explained in more detail below with reference to the drawing, in which:

Fig. 1 shows a perspective view of a covering panel of a false wall according to the invention as seen from the back side,

Fig. 2 shows a corner region of the covering panel from Fig. 1 in more detail,

Fig. 3 shows a plan view of the way in which the covering panel from Fig. 1 is attached to a rear wall,

Fig. 4 shows a side view of a covering panel placed in an underlay profile and base profile of a false wall according to the invention, and

Fig. 5 shows a cross-sectional view of a joint profile for a false wall according to the invention. Fig. 1 shows part of a false wall according to the invention. The false wall comprises one or more covering panels 1 which are placed adjacent to one another and have their underside placed on a floor 2. The covering panel 1 has a back side 11 and a visible side 12. The covering panel 1 may be made from plastic or may be covered with plastic. Other materials are also possible. The visible side has preferably been finished in such a way that no further finishing of the wall is required after the panels 1 have been put in place.

An internally threaded bush 3 has been countersunk into the back side 11 of the panel 1 in the vicinity of the top side 13 and each side edge 14 of the covering panel 1, as shown in Fig. 2. This bush 3 may be glued into the panel. Alternatively, the bush 3 may also be arranged on the back side 11 of the covering panel 1. It would also be possible for a nut to be arranged on or in the back side 11. A threaded rod 4 is screwed into this bush 3 and preferably in each case locked using a nut 50 (see Fig. 3). It is also possible to arrange an additional threaded rod 4 further down.

The false wall also comprises a frame having a, preferably metal, base profile 5, in particular a C-profile which extends at a certain distance from and substantially parallel to the rear wall. The base profile 5 is arranged on an underlay profile 6 placed on the ground.

The underlay profile 6 comprises a base strip 61 with a rear longitudinal wall 62 extending upwards therefrom, a middle longitudinal wall 63 and a front longitudinal wall 64. The rear longitudinal wall 62 and the middle longitudinal wall 63, together with the base strip 61 , form a groove 65 in which the underside of the base profile 5 can be placed. The middle longitudinal wall 63 and the front longitudinal wall 64 together with the base strip 61 form a second groove 66 in which the underside of the covering panel 1 can be placed, as can be seen from Fig. 1 and Fig. 4. The front longitudinal wall 64 extends obliquely upwards and in the direction of the adjacent middle longitudinal wall 63, in order to clamp onto the front side 12 of the covering panel 1.

The underlay profile 6 is preferably made from plastic, for example PVC. The base strip 61 and the longitudinal walls are made from a relatively rigid material, for example hard PVC. As an alternative to plastic, the underlay profile may also be made from rubber or from metal with a rubber or plastic covering layer.

Longitudinal ribs 67, 68 of soft material, for example soft PVC or rubber, are formed on the underside of the base strip 61. On the front side of the base strip is preferably formed a sealing lip 69 which extends over the length and is made from a flexible material, for example soft PVC or rubber. The ribs 67, 68 and the sealing lip 69 are preferably formed on the base strip 61 by means of co-extrusion. The ribs 67, 68 and the sealing lip 69 could also be fitted to the base strip in some other way, for example by gluing. The deformability of the ribs 67, 68 makes it possible to compensate for irregularities in the floor surface. Furthermore, the ribs 67, 68 provide a vibration-damping action between the floor and the false wall. When the profile 6 is being placed on the floor, the sealing lip 69 is deformed, resulting in a strong sealing action with respect to moisture, which is important in wet rooms, such as bathrooms.

The height of the base profile 5 can also be locally adjusted by placing a sliding nut in the profiled section 5 and screwing through it a bolt, the end of which fits through an opening in the bottom of the profile 5. As a result, the base profile 5 is lifted with respect to the underlay profile 6, which is pressed onto the floor surface 2, so that the base profile 5 can, for example, be made level.

In a conceivable variant (not shown), just one underlay profile in the form of a groove (U-profile or the like) is used, in order for the underside of the covering panels 1 to be placed therein, while the base profile 5 is, for example, arranged directly on the floor surface.

The frame of the false wall also comprises a wall profile 7 of C-shaped cross section, which is preferably made from metal but may also be made from another suitable material. The wall profile 7 is arranged substantially horizontally on the rear wall 8. An underlay profile 6 is arranged between the rear wall 8 and the metal wall profile 7 (cf. Fig. 3), in a similar way to that in which the underlay profile 6 is used on the floor surface. Furthermore, the frame comprises a plurality of upright profiles 9 which extend substantially vertically upwards from the base profile 5. The upright profiles 9 are preferably C-profiles, preferably made from metal, and at their bottom end are in each case suitably connected to the base profile 5. A top end of the upright profile 9 is connected to the wall profile 7 by means of a connecting part.

In the example shown, the connecting part comprises an angle piece 20 which is connected to the wall profile 7 by means of a sliding nut 21 and a bolt 22. It also comprises a second angle piece 23, which is connected to the upright profile 9 via a sliding nut 24 and a bolt 25.

That part 20a of the angle piece 20 which extends substantially perpendicularly to the wall profile 7 and that part 23a which extends substantially perpendicularly to the upright profile 9 bear against one another and are connected to one another by means of a nut-and-bolt connection. Preferably, the parts 20a and 23a of the angle pieces 20 and 23, respectively, are each provided with a slotted hole (not shown), so that the distance between the upright profile 9 and the wall profile 7 can be adjusted. In this way, the false wall can be adjusted, for example in the event of a rear wall 8 that is not completely at right angles to the floor 2 or a side wall. The upright profile 9 is preferably of C-shaped cross section and has a top side with a longitudinal slot delimited by flanges 92. The upright profile 9 also has a base 93 located on the opposite side from the top side. At the top side of the upright profile 9, a clamping plate 30 is clamped onto the top side of the upright profile 9 by means of the bolt 25 and the nut 24 via the angle piece 23. The angle piece 23 could fundamentally also be welded to the clamping plate 30.

In the vicinity of its ends, the clamping plate 30 is provided with holes for the threaded stubs 4 arranged on the covering panels 1 to fit through. The covering panels 1 can be tightened with respect to the clamping plate 30 by means of nuts 31 which are screwed onto the threaded stubs 4, resulting in a robust false wall construction. It would in theory also be possible for threaded rods 4 to be arranged on the back side 11 of the covering panel 1 , for example halfway up the covering panels 1 , which would then be coupled to the upright profile 9 in a similar way to that described above.

A joint profile 40 is in each case arranged between the end edges of the covering panels 1. The joint profile 40 is preferably made from a flexible plastic or rubber. The joint profile 40 comprises a flexible joint piece 41 which, in the assembled state, is located between two opposite end edges of two adjacent covering panels 1. The joint piece 41 is preferably formed as a hollow profile, as can be seen in Fig. 5. The joint profile 40 also has a back strip 42 which is connected to an end of the joint piece 41 that in the assembled state is located on the back side 11 of the covering panels 1. In the assembled state, the back strip 42 is located between the back side 11 of the adjacently positioned covering plates 1 and the upright profile 9, as shown in Fig. 3. Although this is not shown in the figure, the back strip 42 may be provided on one or both sides with grooves in order to enhance the vibration- damping action. Furthermore, sealing ribs 43 are provided, which are connected to that end of the joint piece 41 which in the assembled state is located on the visible side 12 of the covering panels 1 and extend in the transverse direction therefrom. The sealing ribs 43 engage around the edges of the covering panels 1 on the visible side 12 and ensure moisture-tightness.

During assembly, when the nuts 31 have not yet been completely tightened on the threaded rods 4, the joint profile 40 is pulled through from the top downwards between the end edges of the covering panels 1. Then, the nuts 31 are tightened, with the result that the joint profile 40 is fixed in place by means of the clamping action of the back strip 42. The flexibility of the joint piece 41 allows the covering panels 1 to be adjusted with respect to one another, so that the covering panels 1 can be aligned with one another in order to form a flat wall.
