Description

Title of the invention: FINISHING ELEMENT FOR A SECTION OF WALL technical field

[0001] The invention relates to a finishing element for a section of wall, in particular a finishing element for a reveal, a column side, a wall, or a ceiling. More specifically, the element is a plasterboard panel with an integrated micro-mesh profile for finishing a plasterboard wall or for finishing a wall with thin plaster. In a second aspect, the invention also relates to a method for manufacturing the element.

[0002] THE STATE OF THE ART

[0003] Reveal plates are essential construction elements used to finish the transition between the window or door frame and the wall. Traditionally, reveals are finished with plaster. When applying the plaster, standard profiles are used at the transition between the two surfaces. The profiles create straight, clean lines, protect vulnerable corners, and reinforce the plaster so that it is less likely to crack or chip. However, applying profiles is a lengthy and laborious process. In addition, the windows must be covered with masking tape, as the plaster is spread along the window. This method also makes it more difficult to achieve a perfectly flat finish.

[0004] BE1025362B1 offers a solution to laborious profiling by describing plates Plasterboard with an integrated plaster profile. These prefabricated plasterboards with integrated corner profiles can be easily installed by a plasterer or DIY enthusiast. Since the reveals no longer need to be plastered, the windows no longer need to be covered with tape, saving both labor and materials. The integrated plaster profile has two feet or flanges and a corner edge, and is symmetrical in the transverse direction. The flanges of the profile contain openings that are identical in number and position on both flanges, so the integrated plaster profile is also symmetrical in the longitudinal direction of the plasterboard. The profile has relatively few openings per cm², which enhances its strength. The profile is designed to connect a plasterboard to a wall to be plastered. The corner edge of the profile extends 7 mm beyond the plane defined by the flange that connects it to the wall to be plastered.A layer of approximately 7 mm of wet plaster is then applied to the wall, also known as plastering. using the corner edge of the integrated profile as a guide for applying the plaster.

[0005] One of the problems is that, due to the thickness of the angle profile, the element cannot be used for applying a thin coating or for finishing a wall on which a plasterboard is fixed.

[0006] The object of the present invention is to provide a solution to this problem by developing a finishing profile comprising two flanges and a corner edge, wherein the corner edge extends by no more than 3 mm beyond the plane defined by one of the two flanges. The finishing profile of the present invention is further asymmetrical in the longitudinal direction due to a different number of gripping openings in the two flanges. The profile comprises a robust leg or flange without openings or with a limited number of openings, optimized for bonding to a plasterboard, and a leg made of a fine micro-mesh optimized for a thin (plaster) finish. For a perfect finish, the wall or plasterboard to be finished, to which the element of the present invention is attached, must be finished with one or more coats of finish only over a width of approximately 35 to 45 cm from the corner edge of the integrated profile.The final finishing layer is up to 3 mm thick at its closest point to the corner profile and flattens out towards it. This contrasts with the profile described in document BE1025362B1, where a 7 mm thick plaster is required across the entire wall to complete the finish. Furthermore, thanks to the present invention, the element with the integrated profile can also be used for finishing a section of wall made of plasterboard, since plasterboard is compatible with thin filler and finishing layers, but not with wet plaster.

[0007] In summary, thanks to the new profile of the reveal, it can be used for connecting to plasterboard, among other things, while applying only a thin finishing coat, resulting in significant savings in material and labor costs. Furthermore, the installation time for the reveals can be reduced, thereby improving the efficiency of construction projects. Summary of the invention

[0008] To this end, the invention relates to a finishing element for a section of wall, characterized in that the element comprises a strip-shaped plasterboard panel provided on at least one longitudinal edge with an accessory for creating a corner to which the panel and a finishing layer can then be attached, the accessory having an angular profile consisting of a corner edge and two flanges, a first flange being fixed in the panel and a second flange, more particularly a fixing and / or attachment flange, extending angularly with respect to the plate, the edge not exceeding by more than 3 mm the plane defined by the second flange.

[0009] Consequently, it is not necessary to completely cover the surface to which the second flange is attached with, for example, a 7 mm thick coating, as is the case in the current state of the art, but it is sufficient to apply a maximum of 3 mm of finish, for example, a thin coat of plaster to the wall or to the plasterboard panels that make up the wall connected to the second flange. When finishing a plasterboard wall, the finishing layer, with a maximum thickness of 3 mm, is applied using fillers and finishing agents traditionally used for finishing plasterboard. The element of the invention makes it possible to obtain a perfect finish if the final finishing layer is applied only to a width of approximately 35 to 45 cm measured from the accessory.

[0010] In a specific embodiment, the angle profile is asymmetrical with respect to the longitudinal direction. More precisely, the asymmetry is obtained because the two flanges are provided with a different number of gripping openings per unit area.

[0011] The first flange is designed to securely anchor the corner profile to the panel. To achieve this, the first flange has few or no larger openings, for example, a maximum of one gripping opening per cm². The free-standing gripping openings in the second flange are designed to provide a solid bond between the element on one side and the finishing layer on the other, with a thin finishing layer, and to allow the profile to be mechanically fixed to the wall to be finished, for example, by stapling. To this end, a large number of small openings are provided in the second flange, for example, at least five gripping openings per cm². This contrasts with the original design, where a panel was supplied with an integrated corner profile that was symmetrical in the longitudinal direction and had the same number of gripping openings per unit area in both flanges.

[0012] In another embodiment, the invention relates to a device which, on the one hand, during manufacturing, promotes the flow of glue through the gripping openings, thus reducing the mobility of the angle profile in the plate, or the risk of the angle profile detaching from the plate, and, on the other hand, during finishing, ensures that the adhesion of the angle profile to the plaster and the glue is uniform, so that a balanced bond without weak points can be obtained.

[0013] In another embodiment, the element of the invention reinforces the rigidity of the plate at the end of the slot and thus remedies the frequent cracking or breakage of the traditional model at this point.

[0014] In another aspect, the present invention relates to a method of manufacturing such an element, characterized in that it consists of forming a plasterboard in the shape of a strip; inserting a slot in at least one longitudinal edge of the board; and inserting and fixing in this slot with a flange an angle profile as described in this document.

[0015] In yet another aspect, the present invention relates to a use of the element as described above, characterized in that this method consists of putting the element in length and width; fixing said element to the unfinished reveal; and finishing the part of the wall to which the second flange of the accessory connects, the aforementioned element, more particularly the accessory belonging to it, being used as a guide for the finishing.

[0016] In a final aspect, the present invention relates to an angle profile comprising two flanges having gripping openings, wherein the angle profile is asymmetrical in the longitudinal direction due to the presence of a different number of gripping openings per unit area in the two flanges, and wherein the angle profile is configured such that the shortest distance between the angle edge of the angle profile and the plane defined by the second flange is at most 3 mm. In another embodiment, a first flange comprises on average at most 1 gripping opening per cm² and a second flange comprises on average at least 5 gripping openings per cm². DETAILED DESCRIPTION

[0017] Unless otherwise defined, all terms used in the description of the invention, including technical and scientific terms, have the meaning generally understood by persons competent in the technical field of the invention. For a better understanding of the description of the invention, the following terms are explicitly explained.

[0018] When the terms "approximately" or "about" are used in this document with respect to a measurable quantity, parameter, time, or moment, etc., they mean variations of + / -20% or less, preferably + / -10% or less, more preferably + / -5% or less, even more preferably + / -1% or less, and even more preferably + / -0.1% or less with respect to the stated value, insofar as the variations are applicable in the described invention. However, this should be understood as meaning that the value of the quantity to which the term "approximately" or "about" is used is itself specifically disclosed.

[0019] The terms "comprendre", "compprenant", "contenir", "contenant", "comporter", "comportant", "inclu" and "incluant" are synonymous and are inclusive or open terms indicating the presence of the following, and do not exclude the presence of others components, characteristics, elements, members, stages, known from the prior art or described therein.

[0020] Quoting numeric intervals by the endpoints includes all integers, fractions and / or real numbers between the endpoints, including those endpoints.

[0021] The term "reveal" refers to the inner surface of the material surrounding an opening (for example, a window or a door).

[0022] In this document, the term "angle profile" describes an element composed of two legs that form an angle or angle edge between them, when this element has only one cross-section, which is small compared to the length of the element.

[0023] The term "flange" (plural "flanges") is used in this document to describe a leg of the aforementioned angle profile. A distinction is made here between the "first flange," the leg of the angle profile located or intended to be located in the plasterboard, and the "second flange," the leg of the angle profile located or intended to be located in the finishing layer.

[0024] The term "longitudinal edge" is used in this document to describe the thin lateral edges of the strip-shaped plasterboard. Preferably, this term is used to describe the thin lateral edges along the length of the strip-shaped plasterboard.

[0025] In a first aspect, the invention relates to an accessory, also called an angle profile, intended for finishing corners such as the transition between a profile and a wall perpendicular to it. Angle profiles ensure the strength and support of plastering work and are essential in the construction industry. In the first aspect, the angle profile is preferably made of stainless steel and / or galvanized steel or aluminum, preferably with a thickness of approximately 0.5 mm, since these metals are characterized by high corrosion resistance, thus resulting in a durable angle profile. In another embodiment, the angle profile is made of plastic. The angle profile of the invention consists of two flanges (15, 16) with a length preferably between 1.5 and 4 cm. In a specific embodiment, the angle profile is asymmetrical along the bisector of the angle of the angle of the angle profile.Preferably, the first flange (15) applied in the slot of a plasterboard has a length of 1.5 to 2.5 cm. In a specific embodiment, the first flange (15) preferably has a length of 1.7 to 2.2 cm, or 1.8 to 2 cm, or approximately 1.9 cm. Preferably, the second flange (16) has a length of 2.5 to 4 cm. In a particular embodiment, the second flange (16) preferably has a length of 2.8 to 3.8 cm, or 3 to 3.5 cm, or approximately 3.1 cm, or approximately 3.2 cm. In a particular embodiment, the second flange (16) is... longer than the first flange (15). Therefore, in this particular embodiment, the angle profile (11) is asymmetrical in a cross-sectional view.

[0026] In another embodiment, the angle profile (11) is asymmetric in cross-section in the sense that the angle edge (17) extends further from the plane defined by the first flange (15) than from the plane defined by the second flange (16), or in other words in the sense that the distance of the angle edge (17) perpendicular to the plane defined by the first flange (15) is greater than the distance of the angle edge (17) perpendicular to the plane defined by the second flange (16).

[0027] In another embodiment, the accessory is configured so that the second flange (16) protrudes by a maximum of 4 mm, 3.5 mm, 3 mm, 2.5 mm, 2 mm, 1.8 mm or about 1.6 mm from the wall (wall 7 or plasterboard 24) perpendicular to the reveal on which the flange is fixed or so that the distance between the second flange (16) and the wall (plasterboard 24 or wall 7) perpendicular to the reveal on which the flange is fixed is a maximum of 4 mm, 3.5 mm, 3 mm, 2.5 mm, 2 mm or 1.8 mm or about 1.6 mm. To do this, the part (17) defining the corner edge of the accessory protrudes by at most 4 mm, at most 3.5 mm, at most 3 mm, at most 2.5 mm, at most 2 mm, or at most 1.8 mm or about 1.6 mm from the plane defined by the second flange (16).Thanks to the very fine mesh gripping openings of the second flange, after the finishing coat has been spread and hardened on the aforementioned second flange, a solid bond is created between the element and the finish. If the second flange protrudes by no more than 3 mm from the plasterboard or the wall positioned perpendicular to the element, only 3 mm of finishing coat needs to be applied, as the corner edge (17) of the corner profile serves as a guide for applying the finishing coat. Furthermore, if the wall is made of plasterboard, a perfect wall finish can be achieved if the finishing coat is applied to a width of approximately 10 to 50 cm from the plasterboard (24) to which the second flange (16) connects, measured from the corner profile.If the previous model described in document BE1025362B1 is used, the wall to which the second flange connects must be entirely covered with a plasterboard thickness of approximately 7 mm. In other words, the advantage of the design described here is that it allows for significant savings in terms of material and labor costs and for finishing structures made of plasterboard.

[0028] The flanges (15, 16) are slightly folded inwards along their upper edge and are provided with gripping openings centered on the flanges, uniformly distributed, the flanges (15, 16) having a different number of gripping openings per unit area. The angle profile is thus asymmetrical in the longitudinal direction. The first flange (15) has no perforations or a series of large perforations or gripping openings (21), while the second flange (16) has a series of small perforations or gripping openings (22). The number of gripping openings per unit area in the second flange (16) is at least twice the number of gripping openings per unit area in the first flange (15).

[0029] In a specific embodiment, all the gripping openings of a flange are the same size. The size of the gripping openings (21) of the first flange (15) is at least twice that of the gripping openings (22) of the second flange (16). Thanks to the absence of perforations in the first flange (15) or the presence of a limited number of larger perforations in the first flange (15), the corner profile is very securely anchored in the plasterboard and can withstand significant loads or impacts, for example, during the transport and installation of the boards. Thanks to the smaller perforations of the second flange (16), the finishing plaster adheres easily, and the wall or plasterboard construction can be finished more precisely.Therefore, the second flange (16) is also more flexible than the first flange (15), allowing it to adapt to the contours of the wall or plasterboard (24) on which it is to be installed. The fine mesh profile of the second flange (16) also reduces the risk of cracks or splits in the finish and allows it to be mechanically fixed to the surface to be finished using staples, for example, resulting in a more durable and aesthetically pleasing outcome.

[0030] In one specific embodiment, the first flange (15) contains, on average over the entire surface of the flange, no more than 1 gripping opening per cm², no more than 0.75 gripping openings per cm², no more than 0.5 gripping openings per cm², or no more than 0.25 gripping openings per cm². In another specific embodiment, the size of the gripping openings (21) in the first flange (15) is between 0.5 and 1.5 cm², between 0.8 and 1.2 cm², between 0.9 and 1.1 cm², or is approximately 1 cm².

[0031] In another specific embodiment, the second flange (16) comprises, on average over the entire surface of the flange, at least 5 gripping openings per cm², at least 6 gripping openings per cm², at least 7 gripping openings per cm², at least 8 gripping openings per cm², at least 9 gripping openings per cm², or at least 10 gripping openings per cm². In another specific embodiment, the size of the gripping openings (22) in the second flange (16) is between 2 and 15 mm², between 3 and 12 mm², between 4 and 10 mm², between 5 and 8 mm², or approximately 6 mm², or is approximately 7 mm².

[0032] The edges (15, 16) further define a rounded corner edge, so that when the corner profile with the first flange is inserted into the slot of a plasterboard (see below), this corner edge adapts to the extension of the surface exterior of the plate. The resulting narrow slot (23) on the outer surface is filled with a sealant, so that the outer surface of the element is not embossed and can easily be finished with, for example, paint. The rounded corner edge also provides additional reinforcement, making the corner impact-resistant.

[0033] In a second aspect, the invention relates to a finishing element for a part of a wall, more particularly for a reveal or a column side or a wall or a ceiling, in which the element comprises a strip-shaped plate having a slot in one or more longitudinal edges, an accessory as described in the first aspect of the invention, and an adhesive or other adhesive means by which the accessory is fixed to the plate.

[0034] The aforementioned strip-shaped board is preferably made of plasterboard, that is, a board with a plaster or similar core and two outer layers of cardboard, as it provides a good substrate for both tiling and plastering, and is also available in an impregnated form, making it suitable for use in damp rooms. Plasterboard can also be easily fixed to the section of wall to be finished using screws, adhesives, and / or adhesive plasters.

[0035] The board is provided with a slot on at least one longitudinal edge, which forms an angle, preferably less than 45°, with the outside of the plasterboard. The slot is preferably cut to a depth of 2 to 4 cm into the board, which is preferably 2 to 4 mm thick, so that the deepest point of the slot is located in the center of the board. This slot forms an angle of preferably less than 45° with the outside of the plasterboard, so as to preserve the compressive strength of the board as much as possible. Any corner profile described in the first aspect can be fixed in this slot.

[0036] To produce the element with integrated angle profile described herein, the angle profile (11) with the first flange (15) is inserted into the slot in the plate (Figures 5-6). This slot is provided with a fastening means for securing the angle profile in the plate. The aforementioned gripping openings (21) on the first flange (15) ensure a balanced and durable fastening of the angle profile in the plate because, on the one hand, after the adhesive has hardened, a mechanical bond is created in these openings and, on the other hand, the adhesive can spread sufficiently through these openings in the slot. The aforementioned slight curvature at the top of the first flange also contributes to an effective assembly of the angle profile in the plate, as the hardened adhesive can adhere better due to this difference in relief. This reduces the mobility of the angle profile in the plate, or the risk of the angle profile detaching from the plate.

[0037] In a third aspect, the invention relates to a method for manufacturing said element. According to the invention, the aforementioned element is preferably constructed as a prefabricated element, in which the angle profile is fixed in the plate during manufacturing. The manufacture of this element comprises the following steps:

[0038] - the formation of a strip-shaped plate from a plasterboard;

[0039] - making a slot (19) in at least one longitudinal edge (10) of the plate (9);

[0040] - the installation and fixing in this slot (19) with the first flange (15) of a angular profile (11) described in the first aspect of the invention by means of an adhesive; and

[0041] - the filling of the open joint between the angle profile and the longitudinal edge of the plate using a sealant.

[0042] Depending on the application, plasterboard can be manufactured in different dimensions.

[0043] The slot is preferably made in the plate by milling, so as to obtain a uniform slot. A slot can also be made on several longitudinal edges, for example in the case of a four-sided column cladding. In this case, the two longitudinal edges of the plate are provided with a slot into which an adhesive and an angle profile are inserted. The element can thus be applied to the two opposite sides of the column, after which the other sides can be finished with conventional plaster.

[0044] When the angle profile with the first flange is inserted into the slot in the plate, the angle edge adapts to the extension of the outer surface of the plate. The narrow slot thus created on the outer surface is filled with a sealant, so that the outer surface of the element is not embossed and can easily be painted, for example.

[0045] In a fourth aspect, the invention relates to a method for finishing a reveal, column, wall, or ceiling, using one of the elements with an integrated corner profile described herein. This method comprises the following steps:

[0046] - resize an element with an integrated corner profile, as described in the second aspect of the invention;

[0047] - fix the element to the reveal or to the unfinished part of the wall, for example using screws or glue and / or adhesive coating;

[0048] - the finishing of at least part of the side of the wall to which the corner profile is fixed, in using the angle profile as a guide for finishing.

[0049] In a particular embodiment, the element is fixed to the unfinished reveal or part of the wall using screws and / or glue and / or adhesive plaster.

[0050] In another specific embodiment, glue and / or adhesive compound are applied to the reveal or unfinished part of the wall and / or to the element, after which the element is pressed and positioned against the reveal or unfinished part of the wall. When the glue and / or adhesive compound has sufficiently hardened, the assembly can be completed according to the method described above.

[0051] In another specific embodiment, the second flange (16) of the element is connected to a wall and the whole assembly is covered with a thin coat of plaster. The term "thin coat," as used here, refers to a type of sprayable plaster that is particularly well suited for use in new construction.

[0052] "Plastering" is a plaster whose average thickness is generally around 10 mm. Plastering is generally applied as a conventional interior coating on common masonry, concrete blocks, building bricks, etc.

[0053] In another specific embodiment, the second flange (16) connects to a wall constructed or composed of plasterboard, and the assembly is finished with a traditional plasterboard finish. Here, thin plaster is not used, but mastic plasters are applied as a filler or jointing layer and / or as a finishing layer.

[0054] Thanks to the free gripping openings and the slight curvature of the edge of the second flange, a robust bond is created between the element on the one hand and the finish on the other hand after the spreading and hardening of the finishing layers on the aforementioned second flange (16) of the integrated angle profile.

[0055] The flat edge of the profile allows for quick and easy installation of the finishing coats. Furthermore, thanks to the design of the corner profile described here, only 3 mm of finish coat needs to be applied to the board or wall connected to the second flange (16) of the corner profile. If the wall to which the second flange connects is made of plasterboard, it is even sufficient to apply the finishing coat to only a portion of the wall to be finished to obtain a perfectly finished result. Indeed, the very small difference in thickness is not visually perceptible because the finishing coat is applied over a width of approximately 35 cm, with the thickness decreasing over this width. In a specific application, the finishing coat only needs to be applied over a width of approximately 10 cm, approximately 20 cm, approximately 28 cm, approximately 35 cm, or approximately 45 cm from the corner profile.In another specific embodiment, the finishing layer only needs to be applied to a width between 10 and 60 cm, between 15 and 55 cm, between 20 and 50 cm, between 25 and 45 cm, or between 30 and 40 cm, calculated or measured from the corner profile. This contrasts with the prior art, where, after installing a plasterboard with an integrated corner profile, a 7 mm thick layer of plaster must be applied over it. the entire wall which connects to the second flange (16) and is not compatible with the finishing of a wall made of plasterboard.

[0056] The present invention will be described in more detail below, with reference to non-limiting figures. DESCRIPTION OF THE FIGURES

[0057] In order to better demonstrate the features of the invention, an embodiment is described below by way of example without limitation, with reference to the accompanying figures, in which:

[0058] - Fig. 1 schematically represents a window in a finished version of a splay with a traditional splay element.

[0059] - Figure 2, on a larger scale, shows a cross-section of the element of the traditional reveal along line II-II of [Fig.l], after application of the plaster;

[0061] - [Fig. 4], at the same scale as Figures 2 and 3, shows a cross-section of the reveal element of the present invention after the application of one or more finishing coats on a wall made of a plasterboard (24).

[0062] - Fig. 5 and Fig. 6 show how the element is manufactured according to the invention;

[0063] - Figures [Fig.7], [Fig.8] and [Fig.9] show how the angle profile is constructed, whose flange (15) which is integrated into the plate has a limited number of large gripping openings (21) necessary for a solid anchoring in the plate, and whose flange (16) is made of a fine mesh having a large number of small gripping openings (22) necessary for a fine and well-fitting plaster finish;

[0064] - Part A and part B of [Fig. 8] show the dimensions and location gripping openings (21, 22) in the first (15) and second (16) straps, respectively;

[0065] - Figure 9 shows the dimensions (in mm) of the different parts of the angle profile (11), as well as the degrees of the different angles;

[0066] - Figure 10 shows in detail how the angle profile is integrated into the element of the invention.

[0067] As shown in Figures 1 to 4, a reveal 1, i.e. the lateral surface of a wall 2 around a window 3 or similar, is finished with a reveal element 4, by fixing it against the reveal, for example using an amount of adhesive and / or adhesive coating 5, as shown in Figures 2, 3 and 4. When the glue and / or Once the adhesive coating 5 has sufficiently hardened, plastering 6 on the wall side 7 can begin immediately. The reveal element can also be fixed using screws or other fastening methods. The advantage of screws is that it is not necessary to wait for the adhesive to fully harden.

[0068] The invention relates to an element 8 with which a part of a wall, such as a reveal 1, can be easily finished during the application of plaster. Figure 6 illustrates a preferred embodiment of such an element 8.

[0069] This element 8 comprises a strip-shaped plate 9 for cladding the part of the wall to be finished, in which said plate 9, in this case having a longitudinal edge 10, is provided with an accessory for making an angle, which accessory in this case is formed by an angle profile 11 extending in the longitudinal direction of the plate 9.

[0070] As illustrated, the plate 9 preferably comprises a plasterboard, that is to say a plate with a core 12 of plaster or similar and two upper layers 13-14 of cardboard.

[0071] The angle profile 11 is preferably made of metal, more particularly stainless steel and / or galvanized steel or aluminum. However, according to the invention, it is not excluded to make it out of other materials, for example plastic.

[0072] Figures 6, 7, 8 and 9 illustrate a preferred embodiment of an angle profile 11. The angle profile 11 comprises a first flange 15 and a second flange 16.

[0073] The angle profile 11 is fixed in the plate 9 using the flange 15 in the plate 9 itself, as shown in figures 5 and 6.

[0074] The second flange 16 forms a fixing and / or attachment flange which extends at an angle relative to the plate 9 and which serves as a guide and connecting element for the finishing layer.

[0075] In cross-section, the flanges 15 and 16 illustrated preferably extend at an angle not exceeding 90°, as shown in [Fig.9].

[0076] The angle profile 11 has a part 17 defining an angle edge, as shown in figures 6 to 9, more precisely a part 17 connecting to the extension of the outer surface 18 of the plate 9.

[0077] Part 17 is preferably circular, so as to provide a small rounded shape at the point of the angle to be made.

[0078] For example, the angle profile 11 is fixed to the plate 9 in the manner illustrated in figures 5 and 6.

[0079] First, as shown in [Fig. 5], a slot 19 is made in the longitudinal edge 10 of the plate 9, for example by milling. As shown in [Fig. 5], the slot 19 is located in one half of the plasterboard 9, which prevents the corner profile 11 from detaching.

[0080] Next, the angle profile 11 is precisely inserted into the slot 19 and fixed there by means of an adhesive 20. This adhesive 20 can first be applied in the slot 19, then, before the adhesive 20 hardens, the angle profile 11 is pressed into this slot.

[0081] It should be noted that the inclined insertion of the flange 15, as well as the fact that the slot 19 is made at an angle in the plate 9, contribute to ensuring that the angle profile 11 is particularly well fixed in the plate 9, even when it is subjected to a tensile load in the direction in the plane of the plate 9 and perpendicular to the longitudinal edge 10.

[0082] As shown in figures 7 to 9, the legs 15 and 16 of the angle profile 11 are provided with means allowing better adhesion, on the one hand, to the glue 20 and, on the other hand, to the coating to be applied subsequently, which consist of gripping openings 21 and 22.

[0083] The fixing openings 21 and 22 are preferably uniform openings that are evenly distributed along the entire length of the legs 15 and 16, so that the fixing points are evenly distributed. In a preferred embodiment, the number of openings in the legs 15 and 16 differs; more specifically, the leg 15 contains a limited number of large openings 21, and the leg 16 contains a large number of small openings 22. In the case of the flange 15, the openings 21 are sized so that the flow of the adhesive is not impeded and a strong bond can be formed between the flange 15 and the element. In the case of the flange 16, the openings 22 are small enough to allow for a fine (plaster) finish.In a preferred embodiment, the flange 16 comprises a network of fine mesh or micromesh openings forming a flexible assembly that allows the flange 16 to adhere securely to the wall perpendicular to the element. Another advantage is that the fine mesh profile allows the flange 16 to be easily stapled to the wall portion, which facilitates installation and finishing and further reduces the thickness of the finish.

[0084] The small open joint between part 17 and the longitudinal edge 10 of plate 9 can be filled, if necessary, with a sealant 23, as shown in [Fig. 10]. A flexible jointing mortar is preferably used for this purpose.

[0085] It should be noted that element 8 is preferably constructed as a prefabricated element, more specifically an element which is assembled before being installed against the part of the wall to be finished, as described below.

[0086] Although, according to the invention, it is not excluded to produce the element 8 on the construction site, provided that a suitable milling machine or a similar machine is available, the prefabricated element will preferably be produced in a factory.

[0087] It should be noted that the elements 8 can be manufactured and marketed in various standard widths, so that if the width is correctly chosen, the element 8 only needs to be cut or trimmed to length.

[0088] The present invention is by no means limited to the embodiments illustrated in the figures, but such a finishing element for a narrow wall section, the manufacturing process for this element and the process for creating a reveal covering using this element can be carried out in different variants without departing from the scope of the invention.

[0089] EXAMPLE

[0090] The invention will now be explained in more detail with the help of the following example, without however being limited to it.

[0091] Example 1. Finishing a reveal connected to a wall (thin plaster)

[0092] For finishing a window reveal without a sill, when the dimensions The window opening measures 50 cm by 50 cm, and four reveal elements, each 49 cm long, are supplied. The plasterboard used for these reveal elements is approximately 1 cm thick. The plasterer will cut the four reveal elements to a width of 10 cm, corresponding to the depth of the window within the reveal.

[0093] It is not strictly necessary for the plasterer to cover the window, as the splay elements facilitate the achievement of a straight finish in the window area, and no finishing is required in the splay part, thus reducing the time required for finishing.

[0094] The plasterer then applies the first reveal element. This can be done using glue and / or adhesive compound and / or screws. The reveal element is placed with one end in a corner of the window opening, so that at the other end of the element there is a 1 cm recess. The plasterer repeats this operation for the three other elements, so that no recesses remain and the entire reveal is covered.

[0095] Now that the reveal elements are in place, the plasterer can complete the transition between the reveal elements and the wall perpendicular to the reveal. To do this, he uses a thin coat of plaster. Here, the plasterer uses the corner edge of the corner profile as a guide for the plaster, which ensures a flat finish. Thanks to the new corner profile described above, which is integrated into the reveal elements, a 3 mm thick layer of plaster is sufficient to achieve a perfect finish ([Fig. 3]). For reveal elements with integrated, state-of-the-art plaster profiles, a 7 mm thick layer of plaster must be applied to the entire wall.

[0096] Example 2. Finishing of a reveal connecting to a plasterboard wall.

[0097] The reveal element described here can also, and preferably, be used for finishing a reveal when the wall perpendicular to the reveal is covered with plasterboard or made of plasterboard ([Fig.4]).

[0098] The reveal elements with integrated finishing profile are attached to the reveal using screws and / or adhesive. The fixing flange (16) is then stapled at several points into the plasterboard (24) to which it is connected. Once all the reveal elements are in place, the plasterer can begin the finishing. Here, the plasterer uses the corner edge of the corner profile as a guide for applying the finishing coat to obtain a flat finish. The finishing coat is applied using a trowel. This first coat is only applied to a width of 10 to 25 cm, depending on the width of the trowel. After the filler coat has dried, one or more finishing coats are applied. These finishing layers are applied again using a trowel, with the thickness of the finishing layer decreasing as you move away from the corner profile.In other words, the finishing layer flattens and blends into the unfinished plasterboard. The presence of the finishing layer, up to 3 mm at the corner profile, and its gradual reduction to its absence on the unfinished plasterboard at, for example, 50 cm from the corner profile, is no longer visually visible.

[0099] Using the new finishing profile, a layer of filler and / or finish over a width of 35 to 45 cm is all that is needed to achieve a perfect finish. For reveal elements with integrated plaster profiles in the prior art, a 7 mm layer of plaster must be applied to the entire wall.
