Description

The invention relates to an angle element for a reveal cladding, having an angled corner element which has two limbs which project at a corner angle and each extend along a covering plane.In new buildings as well as in inventory buildings, individual rooms can be delimited from one another by easily erected separating walls. Such space-limiting, but usually non-load-bearing partitions can be easily and quickly erected with the aid of prefabricated wall elements. In many cases, walls are used which are erected in a stand construction and are covered on one side or on both sides with wall panels. Such dry construction walls have the advantage that they can be quickly erected or removed again if necessary or adapted and optionally offset according to the current requirements.The publication DE 27 52 907 Al describes a panel element for sound protection walls, ceilings, cabins or the like, the sound insulation mat of which is surrounded by a frame consisting of profiles. The profiles are connected via corner brackets. The corner angle and the profiles are fastened by means of screws of a clamping plate designed as an angle profile and insertion legs, which can be inserted completely into the inner contour of the profiles.The publication DE 82 20 471 U1 describes a two-shell, removable and disposable, non-load-bearing partition wall for the subsequent subdivision of rooms, with substantially U-shaped connecting profiles and U-shaped or double-T-shaped intermediate profiles. The connection to the ceiling of the respective room and its walls is effected by means of connecting profiles and to the floor by means of a base or connecting profile.Both in new buildings and in inventory buildings, it is often necessary to provide openings in a wall or wall apertures through which lines, cables or pipes can be passed. In dry construction walls, for this purpose only suitable openings have to be made in the wall panels and insulation or insulation material possibly located between the wall panels has to be removed. In the case of small openings which are arranged adjacent to or at a distance from individual stands of the dry construction wall, it is usually not necessary for the dry construction wall to be separately exposed in the edge regions of the opening. In many cases it is sufficient to cover the individual lamination surfaces which form the edge of the opening in a suitable manner and subsequently to close off or cover the regions of the opening which are not filled by the lines, cables or pipes. Depending on the applicable fire protection regulations, suitable materials must be used and the reveal surfaces of the wall opening must be sealed or covered with fire-resistant material.In the case of larger openings, additional expansion of the dry construction wall is usually required in the edge region around the wall opening. Thus, for example, it is currently prescribed that, in the case of rectangular wall openings having a size of more than 30 cm x 30 cm, a separate frame structure is arranged between the wall panels arranged on both sides of the dry construction wall in order to produce a mechanically sufficiently loadable delimitation of the wall opening in the dry construction wall.In practice, therefore, in the case of larger openings, firstly the wall panels adjoining the opening are removed and the uprights which usually extend from a floor to a ceiling of the dry construction wall and are arranged on both sides of the wall opening are thereby exposed. These vertical posts are provided with horizontally extending interchangeable profiles which frame the lower reveal surface and the upper reveal surface of the wall opening. Vertical stand profiles are then fixed to these horizontally extending interchangeable profiles, which stand profiles delimit the left-hand and right-hand reveal surfaces of the wall opening. These subsequently inserted interchangeable profiles and stand profiles form a mechanically stable frame for the wall opening arranged in the dry construction wall. Subsequently, the wall plates provided with a recess adapted to the wall opening can be attached again to the stand construction and fixed thereto.The effort required for such a mechanical expansion of the frame of a larger wall opening in a dry construction wall is considerable.It is therefore considered an object of the present invention to enable a wall opening in a dry construction wall to be mechanically expanded as simply and quickly as possible. It would be advantageous if the adjacent wall panels of an already erected built-up built-up built-up built-up built-up wall do not have to be removed in order to expose the respectively adjacent vertical uprights of the built-up wall.This object is achieved according to the invention by an angle element having the features of claim 1 and an angle element having the features of claim 2. The angle elements according to the invention have an angled corner element which has two limbs protruding at an angular angle and each extending along a covering plane, wherein an elongate hole is arranged in each limb of the corner element and a stabilizing profile is arranged on at least one of the two limbs, said stabilizing profile at least partially surrounding a cavity, wherein the cavity extends along the covering plane of the associated limb and has a rectangular cross-sectional area transversely with respect to this extension, wherein the at least one stabilizing profile has two stabilizing surfaces extending at right angles from the associated covering plane, such that the angle element can be introduced in a corner of a reveal opening in an interior space between two wall panels of a dry construction wall which are spaced apart from one another in such a way that each of the stabilizing surfaces of the stabilizing profile bears against an associated wall panel or supports it. Such an angle element can be introduced and fixed in a corner of a reveal opening between two wall plates of the dry construction wall which are spaced apart from one another.The two stabilizing surfaces of a stabilizing profile form contact surfaces spaced apart from one another for the two opposite regions of the wall panels adjoining the corner of the reveal opening. Each wall plate can be connected to or fixed to the associated stabilizing surface of a stabilizing profile which lies flat against the relevant wall plate.The stabilizing profile can be, for example, a stand profile which is also used for the vertical stands of the supporting structure of the dry construction wall, on which the wall panels are arranged and fixed on both sides of the stands. The spacing of the two stabilizing surfaces of each stabilizing profile corresponds here expediently to the spacing of the mutually opposite wall panels of the relevant dry construction wall. It is likewise conceivable for planar or three-dimensionally structured spacer elements to be inserted between the stabilizing surfaces and the wall panels and for the wall panels to be supported on the stabilizing surfaces via such spacer elements in order, for example, to be able to adapt the angle element to mining walls of different thicknesses in a simple manner.The angle element can also have a stabilizing profile only on one leg of the corner element. With the second leg of the corner element, on which no stabilizing profile is arranged, the angle element according to the invention can be fixed in a simple manner to a vertical upright profile if the wall opening laterally adjoins the respective upright profile. In this way, in the case of a rectangular wall opening, two of the four angle elements can be fastened to the upright profile, with the result that two further angle elements need only be arranged in the two opposite corners in order to stabilize all four corners of the wall opening.In order to be able to stabilize a corner of the wall opening as well as possible at a distance from a stand profile, it is provided that a stabilizing profile is arranged on each of the two legs of the corner element. The two stabilizing profiles of the angle element according to the invention are connected to one another via the angled corner element with the leg which extends in each case to a covering plane. With such an angle element, a corner of the wall opening in the dry construction wall can be mechanically expanded and reinforced. It is expediently provided that such an angle element is arranged in each corner of the wall opening. The individual reveal surfaces of the wall opening, which extend from one corner to the next corner, can subsequently be covered or filled in a suitable manner.The angled corner element can be produced from a bent sheet metal strip. In most cases it should be expedient for the limbs of the angled corner element which each extend along a covering plane to be oriented at right angles to one another and to form a corner angle of 90°. With such a corner element, rectangular wall openings could be made available. It is likewise conceivable for the angled corner element to have a corner angle deviating from 90°, in order to enable, for example, a triangular or pentagonal cross-sectional area of the wall opening in the dry construction wall, which cross-sectional area is adapted in a suitable manner to the structural circumstances.The stabilizing profile, which is arranged on at least one leg, but often on each of the two legs of the angled corner element, can be, for example, a CW profile also used for the vertical uprights of the dry wall or a U profile adapted with regard to its dimensions. In one embodiment according to the invention, it is provided that at least one of the two stabilizing profiles on the first or second of the two legs forms an element separate from the corner angle, and that each stabilizing profile has a C-shaped cross-sectional area, wherein the mutually facing edge strips of the C-shaped stabilizing profile abut the associated leg of the corner element in the circumferential direction of the cross-sectional area. The two edge strips, which abut the associated leg of the angled corner element, allow a mechanically loadable connection to the leg of the corner element. In addition, the edge strips, which can be brought into contact with the relevant leg, provide a reliable arrangement and alignment of the stabilizing profile on the relevant leg and facilitate the production of the angle element according to the invention. A C-profile can also often be produced more easily than a stabilizing profile closed in the circumferential direction and having a rectangular or square cross-sectional area.According to an embodiment of the invention, it is provided that the edge strips of the C-shaped stabilizing profile facing each other engage around the associated leg of the corner element. The stabilizing profile can be displaced along the leg and fixed at a suitable location, for example by screwing or with the aid of a clamping screw or a clamping device.It is likewise possible and advantageous with regard to a rapid and cost-effective production of the angle element that the corner angle and the at least one stabilizing profile are formed in one piece. The angle element can be produced from a suitable sheet metal blank and can be brought into the desired shape by multiple folding. For this purpose, for example, the sheet metal blank can first be folded over several times in the longitudinal direction and the stabilizing profile can thereby be formed with the two stabilizing surfaces, wherein a C-shaped profile or a profile with a cuboidal cross-sectional surface can be produced for the stabilizing profile. In the case of the stabilizing profile with a cuboidal cross-sectional area, two side edges which are initially located on the outside of the sheet metal blank are bent over in such a way that the two side edges in the finished stabilizing profile bear against one another and thus impart additional mechanical strength to the stabilizing profile. Subsequently, a protruding tongue can be bent transversely to the longitudinal direction in order to generate the corner angle. It is likewise possible for two stabilizing profiles connected to one another via a web to be produced from a sheet metal blank by multiple folding in the longitudinal direction and for the web to subsequently be bent into the corner angle by folding transversely with respect to the longitudinal direction.In order to increase the mechanical rigidity and compressive strength of the angle element according to the invention, it is optionally provided that a pressure-resistant filler material extending from one stabilizing surface to the opposite stabilizing surface is arranged in the cavity of at least one stabilizing profile. The distance between the two stabilizing surfaces of the stabilizing profile is then not only predefined by the dimensional stability and inherent rigidity of the stabilizing profile itself, but is additionally defined and predefined by the pressure-resistant filler material arranged in the cavity of the stabilizing profile. In addition, protruding sections of the pressure-resistant filler material at one or both ends of the stabilizing profile can allow additional mechanical stiffening of the dry construction wall in the region of the corner of the wall opening.As filling material, for example, one strip or several strips of a wall panel of the dry construction wall can be used. In this way, it is possible, for example, to use residues of blanks of the wall panels used for the construction of the dry construction wall that cannot be used otherwise, or else portions of the regions of the wall panels separated out for the production of the wall opening in the dry construction wall that are cut to size accordingly. The filling material for the angle element according to the invention can be cut to size on site and arranged in the cavity of the relevant stabilizing profile or introduced therein. However, suitable blanks of strips of a wall panel can also be produced separately and pre-assembled in the stabilizing profile. It is also possible to produce separate packing elements from another, preferably light, but pressure-resistant filling material, the dimensions of which are adapted to the dimensions of the cavity of the stabilizing profile.In the case of an angle element with two stabilizing profiles, the filling material can protrude laterally in the direction of the other stabilizing profile in the case of one stabilizing profile and completely fill the corner bounded by the two stabilizing profiles. As a result, when an angle element configured in this way is installed in a corner of the wall opening, the cavity between the mutually opposite wall panels of the dry construction wall is filled and stabilized with the filler material in the corner region not covered by the stabilizing profiles.According to an advantageous embodiment of the inventive concept, it is provided that an elongated hole is arranged in each leg of the corner element, which elongated hole extends away from the other leg and is suitable for passing through a screw shank of a fastening screw. With such a fastening screw, for example, the stabilizing profile assigned to the relevant leg can be screwed or fixed to the leg. It is likewise conceivable for two angle elements arranged at a distance from one another in each case in a corner of the wall opening to be connected to one another by means of a suitable reinforcing profile, wherein one end of the reinforcing profile can be fixed to the limb of the corner element and thus to the relevant angle element by means of a fastening screw arranged through an elongate hole of the corner element. By forming an elongated hole in the leg, the arrangement of the fastening screw in a region provided by the dimensions of the elongated hole can be changed and adapted to the structural conditions on site.The invention also relates to a reveal cladding for developing a wall opening in a wall of a dry construction, the dry construction wall having a plurality of uprights which are arranged at a distance from one another and are clad on both sides with wall panels. According to the invention, it is provided that in at least three corners of the wall opening, in each case an angle element with the aforementioned features is arranged between the wall plates, so that in the at least three corners the wall plates lying opposite one another are connected to one another by in each case an angle element, and that in each case adjacently arranged angle elements are connected to one another by a reinforcing profile, wherein each reinforcing profile is fixed at its opposite ends in each case to an associated angle element. The at least three angle elements according to the invention, which are arranged in three corners of a wall opening in a dry construction wall and are each connected to one another via a reinforcing profile, provide a mechanically loadable frame which extends in different spatial directions along the edge of the wall opening, and connects the edge regions of the mutually opposite wall panels of the dry construction wall to one another and keeps them at a distance.It is advantageously provided that the wall opening has a rectangular circumferential edge and an angle element is arranged in each of the four corners. A vertical side edge of the wall opening can be formed by a vertical upright profile of the dry construction wall, to which two angle elements are then fixed, which only have a stabilizing profile, which in the assembled state usually protrudes at right angles from the upright profile. The two angle elements are expediently each fastened to the upright profile by the free leg of the corner element which is not provided with a stabilizing profile.Expediently, an angle element according to the invention is arranged in each corner of the wall opening and, in addition, each angle element is connected to the two adjacently arranged angle elements via stiffening profiles. In this way, the wall opening in the wall of the dry structure is surrounded along its circumference by a closed reinforcing frame which is arranged between the respectively mutually opposite regions of the adjacent wall panels of the dry structure wall and is fixed there. The reinforcing profiles can be designed in such a way that the reveal surfaces of the wall opening are covered and the adjacent cavities between the wall plates lying opposite one another are not accessible from the wall opening. According to an alternative embodiment, the stiffening profiles can also have only one mechanically stiffening function and can be supplemented by separate reveal cladding elements, with which the reveal surfaces are covered.The stiffening profiles can be similar to the stand profiles which are used for the construction of the dry construction wall and are arranged between wall panels lying opposite one another. It is likewise conceivable for the stiffening profiles to each be a U profile, the cross-sectional area of which is adapted to the dimensions of a thickness of the dry construction wall or to a distance of the wall plates of the dry construction wall which are situated opposite one another.According to a particularly advantageous embodiment of the inventive concept, it is provided that the two parallel projecting flange strips of the U-profile of each stiffening profile each bear against an associated wall plate of the dry construction wall. The reinforcing profile can encompass the wall panels lying opposite one another, so that the two flange strips each rest against an outwardly directed outer side of the associated wall panel of the dry construction wall. It is also conceivable that the reinforcing profile can be arranged between mutually opposite wall panels of the dry construction wall and can be introduced into the cavity formed between the wall panels, so that the two parallel projecting flange strips of the U-profile each bear against an inwardly directed inner side of the associated wall panel. In particular in the case of dry construction walls which have a plurality of layers of wall panels arranged one above the other on one side or on both sides of the upright construction, it can also be expedient for a protruding flange strip of the U-profile-shaped stiffening profile to be arranged or inserted between two wall panels which are arranged on one side of the dry construction wall and cover the relevant wall surface of the dry construction wall.The angle element according to the invention, like the complete reveal cladding, is produced from individual parts which, according to an advantageous embodiment of the inventive concept, each consist of non-combustible materials. The angled corner element and the stabilizing profiles can be made of metal at low cost. Both the corner angle and the stabilizing profile can be produced, for example, from a perforated or otherwise slotted metal sheet. A filling material optionally arranged in the cavity of a stabilizing profile can be produced, for example, from one or more blanks of the wall panels also used for the construction of the dry construction wall. Suitable materials for the wall panels are, for example, gypsum board, gypsum fibreboard or rigid foam board. Depending on the fire protection regulations to be fulfilled in each case, the angle element can also be produced from a suitable dimensionally stable plastic material. The filling material can consist, for example, of plastic or of wood. In many cases, however, the use of non-combustible materials will be advantageous. It is likewise conceivable for the filling material to be a mineral insulating material or an intumescent material, so that further advantageous properties for the angle element are made possible with the aid of the filling material.Exemplary embodiments of the inventive concept which are illustrated in the drawing are explained in more detail below. It shows: FIG. 1 shows a schematic illustration of an angle element according to the invention with an angled corner element and with two stabilizing profiles arranged on a respective limb of the corner element, FIG. 2 shows an illustration of an angled corner element of the angled element illustrated in FIG. 1, FIG. 3 is a view of the angle element also shown in FIG. 1, wherein two material strips made of the wall plate material used for the wall plates of the dry construction wall are arranged as a pressure-resistant filling material in each stabilization profile, FIG. 4 shows a corner of a wall opening in a dry construction wall, wherein an angle element according to the invention is arranged in the corner and a 10 reveal surface adjoining the corner is covered with a stiffening profile, FIG. 5 is a schematic representation of a wall panel with a square opening framed by a reveal cladding according to the invention, wherein in an upper region of the wall panel the wall panels lining a stand construction are shown cut and removed, FIG. 6 shows a view of the angle element shown in FIG. 1, wherein a stabilizing profile is arranged only on one leg of the corner element, FIG. 7 is a schematic illustration of a dry construction wall having a rectangular opening framed by a reveal cladding according to the invention, a stand of the stand construction running on a left side of the wall opening, FIG. 8 shows a view according to FIG. 3 of an angle element formed differently therefrom, FIG. 9 shows a view according to FIGS. 3 and 8 of an angle element 1 again formed differently therefrom, FIG. 10 shows a view of an angle element produced in one piece with a stabilizing profile, and FIG. 11 shows a view of an angle element not according to the invention, which is produced in one piece and has two stabilizing profiles.An angle element 1 shown in FIGS. 1 to 3 has an angled corner element 2 shown in isolation in FIG. 2 for the purpose of illustration. The corner element 2 has two limbs 3 which project at a right angle and each extend along a covering plane. The corner angle formed between the two protruding legs 3, which is rectangular in the exemplary embodiments shown in FIGS. 1 to 3, could also have an angle of 60° or 120°, for example, deviating therefrom. The corner element 2 is made of an angled sheet metal strip. If necessary, the corner angle formed between the two legs 3 could be adapted on site to the structural conditions and changed, for example, by bending the corner element 2.In each leg 3 of the corner element 2, an elongated hole 4 is formed, which extends from a bevel 5 connecting the two legs 3 to each other to a respective opposite end 6 of the respective leg 3. The elongated hole 4 could also have a shorter length or instead be formed as a single bore. It is likewise conceivable for a plurality of slots 4 or bores arranged at a distance from one another to be formed in each limb 3 of the corner element 2.Each leg 3 of the corner element 2 is surrounded by a C-shaped stabilizing profile 7. Edge strips 8 of the C-shaped stabilizing profile 7 facing one another engage around the associated leg 3 of the corner element 2 and each lie flat on an associated edge region of the leg 3. The C-shaped stabilizing profile 7 has two mutually opposite stabilizing surfaces 9 which project at right angles from the associated limb 3, and a bottom surface 10. The stabilizing profile 7 delimits a cavity 11 adjoining the associated limb 3. The wall panel strips 12 consist of blanks, optionally produced on site, made of residues of wall panels which are used for the construction of a dry construction wall. The wall plate strips 12 arranged in the cavity 11 of each stabilizing profile 7 form a pressure-resistant filling material, by means of which undesired bending and compression of the two stabilizing surfaces 9 of the stabilizing profile 7 can be prevented. The stabilizing profile 7 with the wall plate strips 12 arranged therein is fixed to the respectively associated leg 3 of the corner element 2 by means of respectively two fastening screws 13. The fastening screws 13 project through the slot 4 formed in the relevant leg 3 in each case. It is possible in principle for the stabilizing profile 7 likewise to have bores or slots in the region of the base surface 10, through which the fastening screws 13 can be passed and fixed, for example, with a fastening nut, which are screwed onto the fastening screws 13 from the outside.FIG. 4 shows a corner 14 of a wall opening 15 in a dry construction wall 16, wherein an angle element 1 according to the invention is arranged in the corner 14 in the configuration shown in FIG. 3. The wall 16 is covered on both sides by a wall plate 17 arranged opposite. The angle element 1 is introduced in the corner 14 of the wall opening 15 between the adjacent edge regions of the wall plates 17 arranged opposite one another and is fixed to the adjacent wall plates 17 by means of suitable fixing screws 18 in the predetermined position in the corner 14 of the wall opening 15. The angle element 1 forms a pressure-proof stiffening of the corner 14 of the wall opening 15 and, due to the suitably selected dimensions of the stabilizing profile 7 and in particular due to the distance of the two stabilizing surfaces 9 from one another, also specifies the distance of the wall plates 17 lying flat against the stabilizing surfaces 9. By arranging the angle element 1 in the corner 14 of the wall opening 15, this region of the wall opening 15 is mechanically expanded and stabilized without it being necessary to remove a wall plate 17 or both wall plates 17 beforehand and to make the corner 14 accessible from the outside over a large area. On a lamination surface 19, which is defined by edges of the wall plates 17 delimiting the wall opening 15, a reinforcing profile 20 covering the lamination surface 19 is arranged. For the purpose of illustration, the section of the angle element 1 arranged under the reinforcing profile 20 is illustrated by dashed lines with the relevant stabilizing profile 7. The reinforcing profile 20 is a U profile, wherein a distance between two parallel protruding flange strips 21 of the reinforcing profile 20 corresponds to a distance predetermined by the mutually opposite outer sides 22, 23 of the wall panels 17, so that each flange strip 21 rests flat from the outside on an associated outer side 22 or 23 of the wall panels 17 adjoining the wall opening 15. With the stiffening profile, which extends from the angle element 1 shown in FIG. 4 up to an adjacent angle element arranged at a distance therefrom, not only is a stable frame formed for the wall opening 15, but at the same time a cavity 24 formed between mutually opposite wall plates 17 of the dry construction wall 16 is also covered.For the purpose of illustration, FIG. 5 shows the dry construction wall 16 which is illustrated merely in a section in FIG. 4 and has a square wall opening 15. The dry construction wall 16 has a plurality of stands 27 which are arranged in each case horizontally spaced apart and extend in the vertical direction from a floor 25 to a ceiling 26, and which are fixed to U-profiles running horizontally on the floor 25 and on the ceiling 26. A central stand 27 has an interruption in the region of the wall opening 15. Each stand is a CW profile which is arranged in such a way that the profile legs of the stand 27 extend in the direction of the wall surface of the dry construction wall 16 and are sufficiently wide in order in each case to be able to fix two edges 28 of mutually adjoining wall panels 17 and 29 along the stand 27 with a joint which is as small as possible at the latter. The wall plate 29 is identical in construction to the wall plates 17 and is designated differently merely for the purpose of illustrating the adjoining edges 28. The course of the posts 27 is indicated by dashed lines in a lower region of FIG. 5 for the purpose of illustration.In each corner of the wall opening 15 an angle element 1 according to the invention is arranged. Each angle element 1 is connected to an adjacently arranged angle element 1 by a reinforcing profile 20. The four angle elements 1 arranged in each case in a corner 14 form, in conjunction with the stiffening profiles 20 fixed thereon, a mechanically stable and pressure-resistant frame structure which delimits and frames the wall opening 15. The reinforcing profiles 20 additionally form a cover for the reveal surfaces 19 of the wall opening 15.In an upper region of the illustration in FIG. 5, the wall panels 17 and 29 arranged on the visible side are cut and partially removed, so that the view of the two angle elements 1 arranged in the upper left corner 14 and in the upper right corner 14 of the wall opening 15 is released. The corresponding sections of the reinforcing profiles 20 connecting these angle elements 1 are shown in dashed lines in these regions.The reveal cladding of the wall opening 15 produced with the angle elements 1 and the reinforcing profiles 20 can be quickly and easily erected on site. In this case, the angle elements 1 are inserted between the wall plates 17 and 29 opposite one another and fixed in the corners 14 of the wall opening 15. The reinforcing profiles 20 can then be pushed on from the outside along the reveal surfaces 19 and connected to the angle elements 1 in order to form the frame structure. Removing the wall plates 17, 29 surrounding the wall opening 15 in order to expose the uprights 27 adjoining the left and right, respectively, and the complicated construction of a frame structure anchored to these adjoining uprights 27 is not necessary when using the angle elements 1 according to the invention.FIG. 6 shows an angle element 1 of different design, wherein a stabilizing profile 7 is arranged only on a leg 3 of the corner element 2. Such an angle element 1 can also be produced on site from an angle element 1 with two stabilizing profiles 7, which is shown for example in FIG. 1, by a rapidly possible dismantling of one of the two stabilizing profiles 7.In Fig. 7 there is shown a schematic representation of a dry construction wall 16 with a rectangular wall opening 15 framed by a reveal cladding according to the invention which forms a mechanically stable frame construction which delimits and frames the wall opening 15. On a side of the wall opening 15 shown on the left in FIG. 7, a stand 27 of the stand construction of the dry construction wall 16 extends. Two angle elements 1 are secured to this stand 27 in each case by a free leg 3 of the corner element 2. The fastening screws used for this purpose can be passed, for example, through the slot 4 in the relevant leg 3 of the corner element and screwed into the stand 27. In the corners 14 of the wall opening 15 opposite the stand 27 and shown on the right in FIG. 7, an angle element 1 is fastened in each case, each with two stabilizing profiles 7 and wall plate strips 12 arranged in each case therein. Adjacent angle elements 1 are connected to one another via reinforcing profiles 20 indicated merely by dashed lines in FIG. 7, no reinforcing profile 20 being necessary on the left side edge in addition to the upright profile 27.In the exemplary embodiment shown in FIG. 8 of an angle element 1 designed differently from the angle element 1 shown in FIGS. 1 to 3, the wall plate strips 12 arranged in one of the two stabilizing profiles 7 project beyond the relevant stabilizing profile 7 and end substantially flush with the bottom surface 10 of the other stabilizing profile 7 or with an outer side of the wall plate strips 12 arranged in the other stabilizing profile 7. In the embodiment shown in FIGS. 1 to 3, this corner region is not filled with a dimensionally stable filling material or not with the wall plate strips 12. In the exemplary embodiment according to FIG. 8, the corner region 28 is additionally mechanically stabilized by the wall plate strips 12.In the exemplary embodiment of an angle element 1 shown by way of example in FIG. 9, which is again configured differently, one of the two stabilizing elements 7 has an extended stabilizing surface 9 which projects into the corner region or completely covers this corner region. The corner region can optionally also be additionally reinforced and mechanically expanded by projecting wall plate strips 12 or a separate filling material. A wall plate 17 abutting the angle element 1 can then also be connected to the angle element 1 in the corner region, wherein the angle element 1 also forms a mechanically loadable support of the abutting wall plate 17 and the reveal cladding produced with the angle element 1 in the corner region.FIGS. 10 and 11 show, by way of example, two variants of an angle element 1 produced in one piece in each case. The angle element shown in FIG. 11 is an embodiment of an angle element which is not according to the invention. The angle element 1 shown in FIG. 10 has a stabilizing profile 7 with a cuboidal cross-sectional area. The stabilizing profile 7 has been produced by multiple folding of a sheet metal blank in the longitudinal direction or along the four longitudinal edges 30 of the stabilizing profile 7, wherein each of the two stabilizing surfaces 9 is in each case bounded in the circumferential direction by two longitudinal edges 30. Two side edges 31 which are still located on the outside of the sheet metal blank rest against one another in the case of the completely folded stabilizing profile 7 and thereby increase the mechanical strength of the stabilizing profile 7. the corner element 2 with the folded legs 3 is formed on the one side by a region of the stabilizing profile 7 and on the other side by a tongue 32, which projects laterally beyond the stabilizing profile 7 in the case of the sheet metal blank and has been folded transversely to the longitudinal direction along the folded edge 5.In the exemplary embodiment shown in FIG. 11, which shows an embodiment not according to the invention, the angle element 1 has two stabilizing profiles 7, which are connected to one another via a connecting web with the bent portion 5, wherein both stabilizing profiles 7 and the connecting web are produced from a single common sheet metal blank by multiple bending.In both cases, in the case of the angle elements 1 produced in one piece, a suitable filling material can be arranged in each case in the cavity 12 formed by the stabilizing profile.
