DESCRIPTION

Angular wall profile

The present invention relates to a false ceiling comprising an angular wall profile that comprises a first erect or vertical wing that extends in the longitudinal direction of the angular wall profile and comprises connection means, which have the shape of a hole for receiving a screw, which connect the angular wall profile to a wall, the angular wall profile being connected to the wall by the connecting means such that the first erect wing extends along the wall, the profile comprising angular wall also a first flange that supports at least one ceiling plate, the first flange being connected to the first erect wing and away from the first erect wing, according to the preamble of the first claim.

A false ceiling usually comprises a grid comprising a plurality of parallel spaced frame members that are connected to each other by one or more transverse profiles. The grid is intended to support ceiling plates. Along the walls, surrounding the false ceiling, several angular wall profiles are usually mounted, which function to support the frame members and the transverse profiles. Each angular wall profile comprises an erect wing, for connection to the surrounding wall, and a flange, to receive the edges of the frame members and the transverse profiles. Examples of angular wall profiles are described for example in document AU-A-2493871 and in US-A-2964148. In document AU-A-2493871, openings are provided to provide tabs to secure profiles at the wall angle and to fix the angular wall profile to the wall. In US-A-2964148 openings are provided to provide springs that rest against edges of plates supported on the angular wall profile to hold them in contact with the following adjacent plates.

A common known problem in relation to the installation of false ceilings is the fact that the wings of the angular wall profiles that run along the wall will follow the surface of the wall to which they are fixed. However, wall surfaces in buildings are rarely perfectly flat and certain tolerances are allowed. As a result, the walls in buildings often have an undulating wall surface. The connection of the erect wing of the angular wall profile to such undulating wall surface results in deformation of the angular wall profile. An undulating wall surface can in particular cause a deformation of the flange of the angular wall profile that supports the edges of the frame members and the transverse profiles. This deformation can result in spaces between the flange edges of the angular wall profile and the ceiling plates that are placed at the top of the flange. These spaces are desirable because they adversely influence the aesthetic vision of the false ceiling.

The deformation of the horizontal flange of the angular wall profile is stronger for angular profiles of thin gauge steel, compared with angular profiles of extruded aluminum wall. However, angular aluminum wall profiles are not always accepted because they are often too heavy from an aesthetic point of view and are not fire resistant compared to the profile variant formed by thin steel rolling. The deformation of the horizontal flange of the angular wall profile as a result of an undulating wall surface also depends on the shape of the angular wall profile. In W-shaped angular wall profiles, for example, the horizontal flange deforms less compared to the L-shaped angular wall profile, because the second erect wing compensates and the undulations to a certain extent.

A known solution to compensate for wall surface deviations is to first mount wooden slats on the wall surface and then fix the erect wing of the angular wall profile to the wooden slats. The lower edge of the wooden slats is often painted black to obtain a floating effect of the false ceiling. The use of wooden slats in order to compensate for the undulations of the wall surface requires a lot of time and is not fire resistant. As a result this solution is not always accepted.

It is therefore an object of the present invention to provide a false ceiling comprising an angular wall profile that compensates for the tensions in the angular wall profile, as a result of the undulations of the wall surface to which the angular wall profile is connected. , in a simplified way.

This is achieved in accordance with the present invention with a false ceiling comprising an angular wall profile showing the technical characteristics of the characterization part of the first claim.

Therefore, the false ceiling according to the present invention is characterized in that the first erect wing comprises at least one fundamentally C-shaped perforation to form a first part in the first erect wing that is movable with respect to the second remaining part in The first erect wing. At least the perforation encloses the connection means and the connection means are located in the first part of the first erect wing so that when fixing the profile to the wall, said first part of the first erect wing will be displaced with respect to the second part in the first erect wing when it finds a ripple and as such will compensate for the ripples on the wall surface to which it is fixed.

At least the perforation in the first erect wing creates a first part that can be displaced with respect to the rest of the profile to compensate for undulations in the wall surface. In fact, because at least the perforation creates an area in the first erect wing with less material, the material between the longitudinal edges of the erect wing and at least the perforation will be displaced with respect to the rest of the profile when mounting the angular profile of wall on a surface of

undulating wall, for example by screwing. The presence of a movable part in the erect wing reduces the risk and possibly eliminates the occurrence of tensions in the angular wall profile. In particular, the risk of the occurrence of stresses in the flange of the angular wall profile that provides a support edge for the ceiling plates is reduced. Thus, the risk of deformation of the first flange is reduced, better contact and support is provided between the first flange of the angular wall profile and the ceiling plate placed at the top of the first flange, and the risk of the occurrence of visible spaces between the first tab and the ceiling plate.

The use of an angular wall profile in the false ceiling according to the present inside provides several additional advantages compared to the use of wooden slats. A first advantage is that the angular wall profile in the false ceiling according to the present invention is suitable for use in clean room situations and hospital environments. Other advantages are that fire resistance can be guaranteed and that assembly takes less time. In fact, the positioning of these angular wall profiles can be done in a single operation, while the use of wooden slats always requires a minimum of two operations, in particular the connection of the wooden slat to the wall and the connection of the angular wall profile to the wooden slat. In most cases, a third operation is even needed, in particular the black paint of the wooden slat to create an improved false ceiling effect. In addition, the application of this type of angular profile from wall to wall can be done by a professional alone, while the application of wood slats in most cases requires two professionals with different experience.

The first tab moves away from the first erect wing. As a result, because the first erect wing extends in the longitudinal direction of the wall after connection of the wall angle to the wall, the first flange moves away from the wall after the connection of the wall angle to the wall. The first flange may extend at any angle with respect to the first erect wing or with respect to the wall. Preferably, the first flange moves away from the first erect wing in a direction perpendicular to the first erect wing or in a direction perpendicular to the wall.

At least the perforation is essentially C-shaped. A C-shaped perforation has the advantage that a lip can be created in the first erect wing that can be folded with respect to the first erect wing. This foldable lip can be used for a number of different applications, in addition to its function as a movable member for mounting the angular wall profile to the wall. The lip that can be folded can, for example, be used as a tool or connection tool for connecting with a cross-sectional profile of a suspended ceiling or for connecting a cross-sectional profile to the angular wall profile. In addition, the lip that can be folded allows the connection between a transverse profile or transverse profile with an angular wall profile to be made by a single person. The connection can be made, in a first operation, by post-cloning the transverse profile or the transverse profile with its opposite end portions transverse in the upper part of the first flange of facing angular wall profiles. In a second operation, the transverse profile or transverse profile can be connected to the angular wall profile by folding the flexible lips of the first erect tabs of said angular wall profile facing on the erect soul of the transverse profile or the transverse profile and connecting them to him.

The size, shape and number of perforations determine the ability of the angular wall profile to compensate for stresses in the angular wall profile. The greater the perforation at least, the greater the first part that is movable with respect to a remaining part of the first erect wing and the more capable the angular wall profile is to compensate for undulations in the wall surface. The person skilled in the art will be able to adjust the number, position and size of the perforations to the wall profile to which the angular wall profile is to be mounted and the stability considered of the profile. Preferably, the angular wall profile comprises a plurality of perforations in the longitudinal direction of the first erect wing. Such angular wall profile makes it possible to compensate stresses along the entire wall surface and prevents and minimizes the risk of the occurrence of visible spaces between the first flange and the false ceiling that is mounted on the angular wall profile. However, when at least the perforation is applied to the first erect wing of the angular wall profile, it should be taken into account that the first erect wing maintains sufficient mechanical strength and folding resistance, to be able to maintain the weight of the members of the roof that are placed on top of the first tab of the angular wall profile.

The invention is further clarified in figs. attached and in the description of the figures.

Figs. 8A and 8B respectively show a cross-section and a three-dimensional view of a fourth preferred embodiment of the angular wall profile for the false ceiling according to the present invention in which the sixth flange extends in a downwardly inclined direction away towards the first flange. .

Fig. 9 shows a cross section of a fourth preferred embodiment of the angular wall profile for the false ceiling according to the present invention in which the sixth flange extends in a direction perpendicular to the first erect wing.

The angular wall profiles 1, 11, 21, 31.41 shown in figs. 1-9, extend in the longitudinal direction of the wall and comprise a first erect or vertical wing 2 and a first flange 5, which are connected to each other in the longitudinal direction of the profile. The connection can be direct, along corresponding longitudinal edges or indirectly through one or more tabs involved.

The first erect wing 2 is provided to connect the angular wall profile 1, 11, 21, 31, 41 to the wall. For this, the first erect wing 2 comprises connection means 10. The connection means 10 have the shape of a hole for receiving a screw as shown in fig. 1. The first erect wing 2 comprises an upper longitudinal edge 4 and a lower longitudinal edge 3. After the connection of the angular wall profile to the wall, the first erect wing extends in the longitudinal direction of the wall. The first erect wing may be a straight vertical wing, or it may comprise a folded part, as shown for example in figs. 8a, 8b and 9.

Preferably, the first erect wing 2 comprises a first edge 63 folded on itself, formed by a part of its upper longitudinal edge 4 that is folded down on an inner face of the first erect wing 2. This has been shown for example in the figs. 3A, 3B and 6. This first edge 63 folded on itself is provided primarily for aesthetic reasons. It is also provided for safety reasons because the first edge 63 folded over itself minimizes the risk of cut injuries resulting from the sharp edges of the angular wall profiles during the manipulation of the angular wall profiles. The edge folded on itself can be folded so that it runs along the face of the first erect wing 2 facing the wall, but is preferably folded so that it runs along the opposite face of the first erect wing 2.

The first flange 5 is provided to support at least one ceiling member 8, such as for example a ceiling plate or a frame member or cross profile of a false ceiling. The first tab 5 is connected to the first erect wing 2 such that, after connecting the first erect wing 2 to the wall, the first tab 5 points outward from the wall. The first flange 5 may extend at any angle with respect to the first erect wing 2 considered suitable by one skilled in the art, but preferably extends in a direction perpendicular to the first erect wing 2, and thus in a direction perpendicular to the wall . The first flange 5 comprises a first longitudinal edge 6, close to the wall, and a second longitudinal edge 7, away from the wall.

Preferably, the first flange 5 comprises a second edge 64 folded on itself, formed by a part of the first flange 5 near its second longitudinal edge 7 which is folded upwardly on an upper face of the first flange. This has been shown for example in figs. 1, 3A, 3B, 4, 5, 6, 8A, 8B and 9. This second edge 64 folded over itself is provided primarily for aesthetic reasons and ensures that only a coated or painted part of the angular wall profile 1 is visible from under the false ceiling.

The first erect wing 2 further comprises at least one perforation 9. The perforation 9 at least forms a first part in the first erect wing 2 which is movable with respect to a second part remaining in the first erect wing 2. By fixing the profile to the wall, said first part in the first erect wing 2 will be displaced with respect to a rest of the first erect wing 2 when it encounters an undulation and as such will compensate for the undulations in the surface of the wall to which it is fixed. Due to its ability to deform, tensions caused by the occurrence of irregularities in the wall can be absorbed by deformation of the erect wing 2, in particular by displacement of the first part. As the tensions are absorbed into the first erect wing 2, the risk of transferring the tension from the erect wing 2 to the first flange 5 and any consequent deformation of the flange 5 is greatly reduced. As a result, the risk of deforming the support surface for the ceiling plates is minimal, the contact between the edge of the ceiling plates mounted on the top of the flange 5 is optimized and the risk of occurrence of visible spaces between the ceiling plate and the first tab 5 is minimal.

The position of at least one perforation 9 on the erect wing 2 can be any position considered suitable by one skilled in the art. At least the perforation 9 can be applied in a middle or central part of the first erect wing 2, or near the lower longitudinal edge 3 or upper 4 of the first erect wing 2. In case at least one perforation 9 is provided near of the upper longitudinal edge 4 of the first erect wing 2, the first erect wing 2 preferably does not comprise a first edge 63 folded on itself as this would reduce the profile capacity

angular wall 1 compensate for undulations on the wall surface. Therefore, the person skilled in the art will seek the optimal compromise between optimum deformation capacity of the erect wing and optimal mechanical strength, stability and support strength of the profile.

Some examples of different shapes and positions of at least one perforation 9 are given in figs. 2a - 2k. At least the perforation 9 shown in fig. 2a, which is not covered by the claims have the form of an elongated groove provided below the connection means 10. At least the perforation 9 shown in fig. 2b, which is not covered by the claims, comprises two elongate grooves, provided one above the connection means 10 and another one provided below the connection means 10. At least the perforation 9 shown in fig. 2c, which is not covered by the claims, comprises two protruding folded parts, one on each side of the connection means 10. At least the perforation 9 shown in figs. 2d-2g comprises two C-shaped grooves. Each of the C-shaped grooves is positioned such that it encloses the connection means 10. The orientation of the C-shaped grooves with respect to the longitudinal edges 3, 4 of the first erect wing and the orientation of the C-shaped grooves with respect to each other may vary as shown in figs. 2d-2g. At least the perforation 9 shown in figs. 2h and 2¡ comprises a first and second elongated grooves that extend at an angle respectively to each other. At least the perforation 9 shown in fig. 2j comprises a circular groove. At least the perforation 9 shown in fig. 2k, which is not covered by the claims, comprises a star-shaped groove.

Preferably, at least the perforation 9 is C-shaped as shown in figs. 2d-2g. A C-shaped perforation comprises three elongated grooves that together form a letter C. A C-shaped perforation has the advantage that within the rectangle defined by said three elongated grooves a lip can be created that can be folded with respect to the first erect wing 2 as shown in figs. 3a and 3b. The lip can be formed by a complete rectangle defined by said three elongated grooves as shown in fig. 3a or by the rectangle only as shown in fig. 3b The orientation of said lip that can be folded can vary depending for example on the orientation of said C-shaped perforation and the amount of bending of the lip. The lip that can be folded can, for example, point outward from the first erect wing 2 to extend in a direction perpendicular to the first erect wing 2 as shown in fig. 3rd. This orientation of the foldable lip is particularly suitable for mounting and connecting a cross-sectional profile of a false ceiling to the angular wall profile 1 as shown in fig. 3rd. The cross section of the false ceiling shown in fig. 3a rests with its horizontal flange on the first flange 5 of the angular wall profile 1 and is connected with its erect soul to the flexible lip of the first erect wing 2 of the angular profile 1, 11, 21, 31, 41 wall. However, any other position of the lip that can be folded with respect to the first erect wing 2 is considered suitable by one skilled in the art. In order to facilitate the connection of the flexible lip to a ceiling member 8, such as a cross-sectional profile, the flexible lip preferably comprises a mounting member. The lip mounting member that can be folded as shown in fig. 3a can comprise, for example, a hole for receiving a screw that can be screwed into the erect core of the transverse profile. However, the mounting member may have any other shape deemed suitable by one skilled in the art. In fig. 3b the lip that can be folded from the angular wall profile is used as a member to maintain a fastener to avoid deformation of the thin ceiling plates.

The connection means 10 for connecting the angular profile 1, 11, 21, 31, 41 from wall to wall can have any position considered suitable by the person skilled in the art with respect to at least the perforation 9 so that the perforation 9 enclose the connection means 10. The position of the connection means 10 is such that they are located in the first part of the first erect wing 2 which is movable with respect to a second part remaining in the first erect wing 2.

The size, shape and number of perforations can be adjusted by the person skilled in the art taking into account the magnitude of the irregularity of the wall. Preferably, the angular wall profile comprises a plurality of perforations in the longitudinal direction of the first erect wing 2 as shown in figs. 2a-2k, allowing compensation of stresses along the entire length of the angular profile 1, 11,21,31,41 wall.

The perforations can be made during or after the production of the angular profile 1, 11, 21, 31, 41 of the wall, for example at the construction site itself. The position, size and number of the perforations 9 can be adjusted to the position of the undulations in the wall surface and to the extent of irregularity of the wall surface. Preferably, the distance between subsequent perforations 9 is set. This allows the perforations 9 to be made during the production of the angular profile 1, 11, 21, 31, 41 of the wall. This can be achieved, for example, with a rotating press roller that rotates substantially at the same speed as the speed at which the angular wall profile 1, 11, 21, 31, 41 is produced, such that the perforations 9 can be formed at the same time and at the same speed as the angular profile itself 1, 11, 21, 31, 41 wall.

At least the perforation 9 can be made in the first erect wing 2 of any type of angular profile 1, 11, 21, 31, 41 of wall considered suitable by the person skilled in the art.

A simple embodiment of an angular wall profile 1 although not covered by the claims is shown in fig. 1. The first flange 5 is directly connected with its first longitudinal edge 6 to the lower longitudinal edge 3 of the first erect wing 2 such that an angular L-shaped wall profile is created. The first erect wing 2 of the angular profile 1 wall shown in fig. 1 comprises at least one perforation 9 in the form of an elongated groove

located below the connection means 10. At least the perforation 9 may however have any other form considered suitable by the person skilled in the art. Upon connection of the first erect wing 2 to the wall, the part between the elongated groove 9 and the lower longitudinal edge 3 of the first erect wing 2 will be movable with respect to a remainder of the first erect wing 2 when it is found with a corrugated wall surface and will minimize the risk of creating tension in the first tab 5.

A preferred embodiment of the angular wall profile 11 for the false ceiling according to the present invention is shown in fig. 4. The angular wall profile 11 comprises a first 5 and a second 15 tabs and a first erect wing 2. The first flange 5 and the second flange 15 are connected with their first longitudinal edges 6, 16 respectively to the lower longitudinal edge 3 and to the upper longitudinal edge 4 of the first erect wing 2 such that a C-shaped angular wall profile is created. The first flange 5 and the second flange 15 can be extended at any angle with respect to each other, but preferably They run in parallel. More preferably the first flange 5 and the second flange 15 both extend perpendicular to the first erect wing 2. The first erect wing 2 of the angular wall profile comprises at least one perforation (not shown) 9 to form a part in the first erect wing 2 which will be movable with respect to a remainder of the first erect wing 2 when the angular wall profile is connected to an undulating wall surface to compensate for a certain extent the undulations in the wall surface. At least the perforation 9 has a C-shape, which allows for example the connection of cross profiles in wall-to-wall applications in a simplified manner. In addition, the C-shape of the angular wall profile allows the transverse profile to be held between the first and second tabs of the angular wall profile, which provides means for improved positioning of the transverse profile with respect to the angular wall profile. Another advantage of the C-shaped angular wall profile is that it results in a further reduction of stresses in the first flange compared to the L-shaped angular wall profile of fig. 1 because part of the tension is transferred and absorbed by the second flange of the angular wall profile. As a result, a C-shaped angular wall profile 11 provides improved resistance against deformation of the first flange 5 of the angular wall profile as a result of a corrugated wall surface compared to an angular shaped wall profile 1 L.

A second preferred embodiment of the angular wall profile 21 for the false ceiling according to the present invention is shown in fig. 5. The angular wall profile 21 comprises a first part 28 of angular wall profile and a second part 29 of angular wall profile that are connected so that they can be disassembled from each other. The first part 28 of the angular wall profile comprises a first erect wing 2 and a third flange 25. The third flange 25 is with its first longitudinal edge 26 directly connected to the lower longitudinal edge 3 of the first erect wing 2, such that the first part 28 of the angular wall profile forms a part of the L-shaped angular wall profile. The first erect wing 2 and the third flange 25 may extend forming any angle with respect to each other, but preferably extend perpendicular respectively between yes. The second part 29 of the angular wall profile comprises a first flange 5, a fourth flange 35 and a second erect wing 12 which are connected to each other in such a way that a part of the C-shaped angular wall profile is formed. , the first flange 5 is with its first longitudinal edge 6 directly connected to the lower longitudinal edge 13 of the second erect wing 12 and the fourth flange 35 is with its first longitudinal edge 36 connected directly to the upper longitudinal edge 14 of the second erect wing 12 The first tab 5 and the fourth tab 35 can be extended at any angle with respect to each other, but preferably run in parallel. More preferably the first flange 5 and the fourth flange 35 both extend perpendicular to the first erect wing 2. The second longitudinal edge 37 of the fourth flange 35 is folded away from the first flange 5 on an outer face of the fourth flange. horizontal 35 so that a third edge 65 is folded over itself. The first part 28 of the angular wall profile and the second part 29 of the angular wall profile are connected such that the third flange 25 is being received within the third edge 65 folded over itself. This 2 part angular wall profile 21 has several advantages. First, the angular wall profile 21 shown in fig. 5 results in a further reduction of stresses in the first flange 5 of the angular wall profile compared to the L-shaped angular profile 1 of fig. 1 and compared to the C-shaped angular wall profile 11 of fig. 4. This stems from the fact that, because the first part 28 of the angular wall profile and the second part 29 of the angular wall profile are connected so that they can be disassembled and do not form a single piece, a deformation of the First part 28 of the angular wall profile is not transferred or is only transferred in a smaller magnitude to the second part 29 of the angular wall profile, and thus to the first flange 5. The angular wall profile 21 thus comprises two zones in the that the stresses are compensated: 1) the first erect wing 2 of the first part 28 of the angular wall profile comprising at least one perforation 9 and 2) the connection between the first part 28 and the second part 29 of the angular wall profile which minimizes the transfer of deformation of the third flange 25 to the first flange 5. A second advantage of the angular wall profile 21 shown in fig. 5 is that it allows to create a floating effect of the false ceiling in a simplified way. For this, the width of the third flange 25 is preferably smaller than the width of the fourth flange 35, such that, after connection of the first part 28 of the angular wall profile to the second part 29 of the angular wall profile , only a part of the third flange 25 of the first part 28 of the angular wall profile is covered by the fourth flange 35 of the second part 29 of the angular wall profile. This uncovered part of the third flange results in a shadow effect, which gives a floating effect to the false ceiling when mounted on the angular wall profile 21. It also allows to obtain a similar effect as that obtained by black wooden slats in a much more simplified way. In fact this effect can be obtained in several different ways. Because the angular wall profile comprises two separate parts of the angular wall profile, these parts can be produced separately and can be made in

Different colors suitable for use. By providing the first part 28 of the angular wall profile in a first dark color, for example in black, and the second part 29 of the angular wall profile in a color similar to that of the ceiling, an effect similar to that obtained with wooden slats can be obtained blacks Another way to obtain a similar effect than that obtained with black wooden slats, is to apply a block of dark seal in the space between the wall and the second erect wing. This sealing block can be made of an acoustically absorbent material or even of a material that expands during fire. In addition, this sealing block can be applied during the production of the angular wall profile in the form of a self-adhesive strip on the bottom of the first flange, such that the angular wall profile can be made by a manufacturer only. A third advantage of the angular wall profile shown in fig. 5 is that the uncovered part of the third flange of the first part of the angular wall profile can be used for different purposes. The uncovered part may for example comprise one or more grooves. These slots can provide ventilation through the angular wall profile and prevent overheating of the air chamber located above the suspended ceiling. The uncovered part can also be used to connect devices that are preferably invisible to the eye, for example for lighting connection.

A third preferred embodiment of the angular profile 31 is shown in figs. 6 and 7. The angular wall profile 31 is a one-piece angular wall profile comprising a first erect wing 2, a fifth flange 45, a third erect wing 22 and a first flange 5. The angular wall profile 31 It is connected to the wall with its first erect wing 2. The first erect wing 2 comprises at least one perforation 9 to compensate for the undulations of the wall surface. The fifth flange 45 is with its first longitudinal edge 46 connected to a lower longitudinal edge 3 of the first erect wing 2 and with its second longitudinal edge 47 connected to an upper longitudinal edge 24 of the third erect wing 22. The third erect wing 22 it points downwards away from the fifth flange 45. The third erect wing 22 may extend at any angle with respect to the first erect wing 2 but preferably extends parallel to the first erect wing 2. The first flange 5, which is intended to receive the roof members, is with the first longitudinal edge 6 connected to the lower longitudinal edge 26 of the third erect wing 22 and points outward from the first erect wing 2. The fifth flange 45 points outward from the first erect wing 2. Any Orientation of the fifth flange 45 with respect to the first erect wing 2 considered suitable by one skilled in the art is possible. Fig. 6 shows an angular wall profile 31 in which the fifth flange 45 moves away from the first erect wing 2 in a direction perpendicular to the first erect wing 2. Fig. 7 shows an angular wall profile 31 in which the fifth flange 45 moves away from the first erect wing 2 in a direction inclined downward towards the first flange 5.

The angular wall profile 31 shown in fig. 6 has a W shape similar to that of fig. 5, with the difference that the angular wall profile 31 as shown in fig. 6 is a one-piece angular wall profile, compared to the 2-piece angular wall profile 21 shown in fig. 5. The angular wall profile 31 shown in fig. 6 has similar advantages to the angular wall profile 21 shown in fig. 5. First, the angular wall profile 31 shown in fig. 6 results in a further reduction of stresses in the first flange 5 of the angular wall profile 31 compared to the L-shaped angular wall profile 1 shown in fig. 1. This reduction is due to the fact of the absorption of tensions at 3 angles: the angle between the first erect wing 2 and the fifth flange 45, the angle between the fifth flange 45 and the third erect wing 22 and the angle between the First flange 5 and the third erect wing 22 absorb each part of the tension created and prevent the transfer of tension to the first wing 5 of the angular wall profile. Secondly, the fifth flange 45 also gives a shadow effect to the angular wall profile 31, which gives the suspended ceiling a floating effect when mounted on the wall. The floating effect can be improved for example by applying a sealing block in the space between the wall and the third erect wing 22 as shown in fig. 6. A third advantage of the angular wall profile shown in fig. 6 is that the fifth flange 45 may comprise ventilation holes or comprise lighting members.

Similar to the angular wall profile 31 shown in fig. 6, the angular wall profile 31 shown in fig. 7 provides a reduction of tension in the first flange 5 of the angular wall profile compared to the angular profile 1 of the L-shaped wall of fig. 1, allows the presence of ventilation holes or lighting members in the fifth flange 45 and gives a certain floating effect to the false ceiling.

A fourth preferred embodiment of the angular wall profile 41 for the false ceiling according to the present invention is shown in figs. 8 and 9. The angular wall profile 41 shown in figs. 8 and 9 comprises a first erect wing 2 that is hidden from behind and connected to a fourth erect wing 32 by a sixth intervention tab 55. The angular wall profile comprises a first flange 5. The angular wall profile 41 is connected to the wall with its first erect wing 2. The first erect wing 2 comprises at least one perforation 9 to compensate for the undulations of the wall surface . The sixth flange 55 is connected to an upper longitudinal edge 4 of the first erect wing 2 with its first longitudinal edge 56 and to an upper longitudinal edge 34 of the fourth erect wing 32 with its second longitudinal edge 7. The fourth erect wing 32 may extend forming any angle with respect to the first erect wing 2 and with respect to the sixth flange 55, but preferably extends parallel to the first erect wing 2 and down from the sixth flange 55. The first flange 5, which is intended to support the roof members, is with a first longitudinal edge 6 connected to the lower longitudinal edge 33 of the fourth erect wing 32 and moves away from the first erect wing 2, preferably in a direction perpendicular to the first erect wing 2. The sixth flange 55 moves away from the first erect wing 2. Any orientation of the sixth flange 55 with respect to the first erect wing 2 considered suitable by one skilled in the art is possible. ble. Fig. 8 shows an angular wall profile 41 in which the sixth flange 55 moves away from the first erect wing 2 in a direction inclined downward towards the first flange 5. Fig. 9 shows an angular wall profile 41 in which the sixth flange 55 moves away from the first erect wing

Similar to the angular wall profile 31 shown in figs. 6 and 7, the angular wall profile 41 shown in figs. 8 and 9 provides an additional improved reduction of tension in the first flange 5 of the angular wall profile compared to the angular profile 1 of the L-shaped wall because part of the tension is absorbed by the sixth flange 55 and not transferred to the first flange 5. This type of angular wall profiles also allows the presence of ventilation holes or lighting members in the sixth flange 55 and gives a certain floating effect to the false ceiling. The ventilation holes in the sixth flange 55 form an additional part that is movable with respect to the rest of the angular wall profile and allows additional compensation of stresses in the angular wall profile.

Preferably, the lower longitudinal edge 3 of the first erect wing 2 of the angular wall profile 41 is folded so that a first suspension hook 61 is formed. The first suspension hook 61 can point outward from the wall as has been shown in fig. 8 or can point towards the wall as shown in fig. 9. The first suspension hook 61 may be used for any purpose deemed suitable by one skilled in the art. It can, for example, be used as an invisible suspension member that can be used to hang a paint or a frame on the wall. This is achieved by folding a part of a lower longitudinal edge 3 of the first erect wing 2 in an upwardly inclined direction, in a direction pointing outward from the first flange 5 or in other words towards the wall. In the example shown in fig. 9 The suspension hook is achieved by folding an end part of the wing 2, however any other method can also be used to provide a suspension hook.

Preferably, the first flange 5 of the angular wall profiles 21, 31, 41 for the false ceiling according to the present invention comprising a space between the first erect wing 2 and another separate erect wing 12, 22, 32, ie a second, third or fourth erect wing comprises a second suspension hook 62. The second suspension hook 62 comprising a part of the first longitudinal edge 6 of the first flange 5 which is folded in a direction inclined towards the wall, ie , a direction pointing outward from the first flange 5, and again towards the first flange 5, such that a second suspension hook 62 is formed. Usually both parts of the suspension hook run along one another. . Although in this embodiment the suspension hook is formed by folding a part of the first flange, any other way of forming a suspension hook can also be used. The suspension hook described above is for example shown in fig. 7. The second suspension hook 62 also reduces the risk of stress occurring in the first flange. This suspension hook 62 also has the advantage that it provides an invisible suspension member that can, for example, be used to hang a paint or a frame to the wall. This type of suspension hook can also be used to mount a finishing or finishing material to the visible bottom face of the first flange. The closing material can for example be in the form of a C-shaped cap and can be applied simply by hooking the closing material behind the angular wall profile. This allows the angular wall profile to be produced from an uncoated material, and provide only that part of the angular wall profile that is visible to the eye with colored trim material.
