Description

The present invention relates to a plaster profile which extends in a longitudinal direction and comprises a corner section and at least one leg which adjoins the corner section transversely to the longitudinal direction. In this case, the corner section can comprise a flat, at least partially closed strip which is bent over along a corner edge that is aligned parallel to the longitudinal direction.

Such plaster profiles can be used in particular as corner profiles due to the corner edge formed in the corner section. In principle, however, expansion joint profiles, connection profiles, end profiles, base profiles or clip-on profiles can also be formed in this way. It is known to form the plaster profile as a whole, i.e. both the corner section and the one or more legs that adjoin the corner section, from a sheet metal strip, in particular continuous along the entire cross section, so that not only the angled surfaces of the Corner portion, but also the respective adjoining legs are designed as at least partially closed surfaces. So that such plaster profiles can be plastered and the plaster reliably adheres to the legs and can preferably also contribute to the attachment of the profile to a component, these surfaces usually have to be structured and / or on their surface in a special way to improve the adhesion of the plaster be provided with openings. The formation of the perforations results in material scrap, which should be avoided as far as possible.

Plaster profiles according to the preamble of claim 1 are, for example, from EP 0 789 115 A1 , EP 0 940 521 A1 as GB 2 292 582 A famous.

It is an object of the invention to provide a plaster profile of the type mentioned at the outset which enables plaster to interlock well at least on the legs of the profile and which can be manufactured in a resource-saving manner.

The object is achieved by a plaster profile with the features of claim 1. Advantageous embodiments emerge from the subclaims, the present description and the figures.

The plaster profile according to the invention extends in a longitudinal direction, wherein it preferably has an at least substantially constant cross section with respect to the longitudinal direction. The plaster profile comprises a corner section and at least one leg which adjoins the corner section transversely to the longitudinal direction. In particular, the corner section and / or the at least one leg each extend in the longitudinal direction. In cross section, a respective leg of the plaster profile represents in particular a linear section which preferably has an at least substantially straight course. Such a line segment of the cross section then corresponds to a surface segment of the plaster profile as which the leg can be designed. The corner section and the respective legs adjoining the corner section are preferably basically parts that are formed separately from one another, the legs being fixedly, in particular permanently, attached to the corner section.

The at least one leg can in particular adjoin the corner section insofar as it extends up to an edge of the corner section, but not or at least not significantly beyond it. In particular, an edge of the leg can be connected to an edge of the corner section. Preferably, there is no overlap between the corner section and the leg a dimension that is required for a reliable connection of the corner section to the leg in view of the particular structure and the particular material. For example, the limb and the corner section can overlap just enough that a welded connection is thereby made possible. Depending on the design of the leg and the corner section, however, a connection at the end, for example welding at the end, may also be possible, so that no overlap is required at all. At the edge of the leg pointing away from the corner section, there is also a reinforcement fabric, which will be described in more detail below.

The corner section comprises a flat strip, which is closed at least in some areas, which is bent over along a corner edge which is aligned parallel to the longitudinal direction. The corner section can in particular be formed from this strip. The strip can be a sheet metal strip, for example. The corner section does not have to have a sharp kink at the corner edge, but can also be bent over in a rounded manner at the corner edge. As a result of the bend along the corner edge, the corner section can have at least two angled, preferably perpendicular, surface sections which are aligned to one another and which are designed to be closed at least in some areas, in particular completely. The corner section can also be bent over several times, in particular along a plurality of mutually parallel edges, by which the corner section is divided into further surface sections, which are preferably each also at least regionally, in particular completely, closed.

The corner edge or a web provided thereon preferably protrudes in at least one direction perpendicular to the longitudinal direction from the entire rest of the plaster profile. In this way, the corner edge or the web is particularly suitable to serve as a pull-off edge for plastering. The corner section can also be designed symmetrically to a mirror plane comprising the corner edge. In which The plaster profile can in particular be a corner profile, an expansion joint profile, a connection profile, an end profile, a base profile or a clip-on profile.

According to the invention, the at least one leg, in particular each leg of the plaster profile, comprises a flat wire structure made of interconnected wires. In particular, the respective leg can be formed from such a flat wire structure. In principle, further structures can be provided on the flat wire structure. However, the flat wire structure preferably extends continuously over the entire longitudinal extent of a respective leg. In this case, at least one reinforcement fabric is provided on the plaster profile, which is partially integrated into the wire structure of a respective leg and protrudes over the respective leg in a direction pointing away from the corner section. The reinforcement fabric can also extend in the longitudinal direction beyond the respective wire structure and in this respect lengthen the respective leg.

The flat wire structure replaces the legs of conventional plaster profiles, which are designed as at least partially closed surfaces. The wire structure, which preferably has no areas of closed surface, has numerous passages through which plaster can penetrate due to its formation of interconnected wires, so that a particularly comprehensive interlocking takes place, through which the plaster adheres well to the plaster profile and at the same time can contribute to its attachment to a substrate. The passages can have a surface area of more than 50%, preferably more than 60%, in particular more than 70%. In addition, by designing a leg as a wire structure, material can be saved compared to a closed surface, especially since no openings have to be punched out, so that no related rejects arise. Furthermore, depending on the specific relative arrangement of the connected wires of the wire structure a comparatively high rigidity of the legs can be achieved. In particular, truss-like structures with many triangular connections can be advantageous in this regard. Furthermore, due to the numerous passages between the wires, a wire structure advantageously results in less heat transfer than a closed structure.

The wires of a respective wire structure can comprise a metal, for example, as a material. All wires of the wire structure of a respective leg, in particular the wires of the wire structures of all legs, of the plaster profile are preferably made of the same material and / or have the same diameter. The wires preferably each have a circular cross section. Alternatively, at least one or more wires can also have other cross-sectional shapes, for example a square or triangular cross-section. The wires are connected to one another at least at certain points. For example, two wires can cross and welded to one another at the crossing point or fastened to one another in some other way. Two wires can also run adjacent to one another at least in sections and be linearly welded to one another or fastened to one another in some other way along such a section.

The wire structure is flat in particular in that it has an at least substantially flat shape. In other words, the flat wire structure can be approximated by an imaginary cuboid, the surfaces of which bear against the wire structure from the outside, the cuboid having a bar shape extending in the longitudinal direction, the cross section of which is significantly wider than it is high, for example with a ratio of the width to the height of at least 3: 1, preferably at least 5: 1.

According to one embodiment, the plaster profile has two legs which adjoin the corner section at opposite edges of the corner section. The edges are preferably aligned parallel to the longitudinal direction and, in particular, are arranged opposite to the aforementioned corner edge, that is to say are arranged on different sides of the corner edge. The two legs preferably extend along the longitudinal direction and can be aligned to one another at an angle of preferably at most 90 °, in particular less than 90 °, preferably between 50 ° and 80 °, for example 60 °. The two legs, in particular all legs of the plaster profile, if it has even more legs, can each be designed in one of the ways described above or below for the at least one leg.

According to a further embodiment, the wire structure does not extend beyond the corner edge, preferably not even as far as the corner edge. In other words, the respective leg and the corner section can indeed at least partially overlap one another. However, the overlap does not go so far that the wire structure of the respective leg reaches or even exceeds the corner edge. Rather, the wire structure of a respective leg is spaced from the corner edge.

If the plaster profile has several legs, it is also preferred that the wire structures of different legs are formed separately from one another. In the case of a plaster profile with several legs, no wire is preferably both part of the wire structure of one of the legs and at the same time part of the wire structure of another of the legs of the plaster profile. In particular, legs are arranged at a distance from one another. The legs can be connected to one another via the corner section.

According to one embodiment, the wire structure comprises at least two wires, which are at least partially parallel to the longitudinal direction or at least to one another are aligned, as well as at least one further wire that connects said at least two wires transversely to their alignment. If the aforementioned at least two wires are not each aligned parallel to one another as a whole, the aforementioned at least one further wire preferably connects sections of these wires that are parallel to one another. The two wires mentioned can in particular have a straight course, at least in sections, preferably as a whole. In principle, however, they can also be parallel to one another with regard to a curved course.

When the following text refers to the two wires or the further wire, the at least two wires mentioned or the at least one further wire mentioned are meant in each case. In particular, the two wires and the further wire are not to be understood as a limitation of the number to exactly two wires or exactly one further wire, but rather more than the two wires mentioned and one further wire can be provided in each case.

The further wire connects the two wires transversely, but not necessarily perpendicular to their respective orientation or to the longitudinal direction. The further wire connects the two wires in particular insofar as it is directly connected on the one hand to one of the two wires and on the other hand also directly to the other of the two wires. This connection can be made, for example, by welding or by hooking the wires together by bending them or by wrapping one wire around the other. The length of the further wire does not have to be limited to the connection of the two wires, but can extend beyond it on one side or on both sides and be directly connected to other wires.

According to a further embodiment, said at least one further wire has a periodic spatial profile and connects the said wire at least two wires multiple times together. For example, the further wire can be connected alternately to one and to the other of the two wires or alternately in each case twice to one and twice to the other of the two wires. The periodic spatial profile can in particular be sinusoidal at least in sections or shaped like a triangular function. In the periodic spatial course, sections with a straight course and sections with a curved course can regularly alternate.

Furthermore, it can be provided that the said at least two wires define a plane within which they run, the said at least one further wire defining a further plane offset in parallel with respect to the said plane, within which it runs. The planes mentioned are not to be understood as infinitely thin in the mathematical sense, but rather as a planar layer with a finite thickness, which preferably corresponds at least essentially to the respective wire diameter. In particular, it can be provided that all wires of a respective wire structure are at least essentially - in particular with the exception of areas in which wires from different levels are directly connected to one another, e.g. welded - either only in one or only in the other of the two levels mentioned get lost. The wires can also be used to define more than two mutually offset planes, for which the same can then apply. Preferably each level comprises at least two wires. In particular, at least one level comprises at least three wires.

However, the wires of a respective flat wire structure are not necessarily restricted to only running in one plane. In particular, according to a further embodiment, the wires of a respective wire structure can also be braided or interwoven with one another. It can be provided in particular that a respective wire changes level and / or is alternately guided over and under other wires.

The wires of a respective flat wire structure can in particular be connected to one another insofar as each wire of the wire structure is connected to every other wire of the same wire structure indirectly or directly via one or more additional wires of the same wire structure. In principle, the geometry of the wire structure can already result in a connection of the wires to one another, for example by twisting or tangling. Preferably, however, the wires are not or not only positively but, at least also, connected to one another with a material fit. In particular, the wires can be welded to one another. In principle, the wires can also be soldered or glued to one another.

According to a further embodiment, a pull-off edge for plastering is formed on the corner edge of the corner section. In the simplest form, the pull-off edge is formed directly by the corner edge. However, it can also be formed by a structure formed on the corner edge, e.g. by a web that extends along the corner edge and in particular can be aligned in the direction of an angle bisector of the angle formed by the bending of the corner section at the corner edge. At the protruding edge of such a web, it can also have a reinforcing structure.

Furthermore, according to one embodiment, it can be provided that the plaster profile has a cover, in particular a plastic cover, which at least partially covers the corner section. In particular, the cover can cover at least the corner edge and / or a structure formed thereon, such as the mentioned web. The pull-off edge can then be formed by the cover.

As already explained above, according to the invention, a reinforcing fabric is provided on the plaster profile, which is thereby attached to a respective leg of the Plaster profile is attached that it is at least partially integrated into the wire structure of a respective leg. The reinforcement fabric can for example be integrated into the wire structure insofar as it is clamped between wires of the wire structure, in particular in areas of welded connections between the wires and / or also in the area of a welded connection between the wire structure and the corner section. Alternatively or in addition, the reinforcement fabric can also be interwoven with the wires. Several reinforcement fabrics can also be provided on the plaster profile, in particular one reinforcement fabric each on different legs of the plaster profile. The reinforcing fabric preferably has a lattice structure made up of several threads or strands, in particular those arranged perpendicularly to one another. The holes in the lattice structure form meshes of the reinforcement fabric. Plaster can penetrate through these meshes of the reinforcement fabric, so that the reinforcement fabric contributes to a reliable anchoring of the plaster profile in the plaster.

If the wire structure comprises at least two wires that define a plane, as well as at least one further wire that defines a further plane offset parallel to said plane, the reinforcing fabric can be arranged between these two planes according to a further embodiment. Wires that define a plane run within this plane. In such an embodiment, the reinforcing fabric can, so to speak, be embedded or clamped between two planes of the wire structure. In this case, wires from different levels can be firmly connected to one another, for example welded to one another, in particular at crossing points. A separate attachment of the reinforcement fabric to the wire structure can then be superfluous, since it can already be sufficiently attached by the clamping effect and / or by the fact that wires from different levels of the wire structure are connected to one another through meshes of the reinforcement fabric.

The plaster profiles 11 shown in the figures extend in the longitudinal direction L, wherein in the Fig. 1 , 2 , 4th , 6th and 8th only a section of the longitudinal extension of the respective plaster profile 11 is shown. The plaster profile 11 extends, for example, over a length of a few meters, for example 1.5 m, 2 m, 2.5 m, 3 m or longer, and can be cut to length as required. The shown section of the respective plaster profile 11 is an example of the formation of the plaster profile 11 over its entire length. In other words, the illustrated embodiment can at least essentially continue or repeat in the longitudinal direction L on one side or on both sides. The cross-section of the plaster profile 11 is essentially constant over the entire longitudinal extension (cf. Fig. 3 ).

That in the Figs. 1 to 3 The plaster profile 11 shown, which is not claimed, comprises a corner section 13 which extends in the longitudinal direction L and is formed by a sheet metal strip which is bent over by approximately 90 ° along a corner edge 15. The corner section 13 is also bent around further edges 17 in such a way that it has a lantern roof-like shape. The areas between the corner edge 15, the further edges 17 and the parallel edges of the corner section 13 each form surface sections of the corner section 13, which are each designed as continuously closed surfaces. The corner section 13 is designed symmetrically with respect to a mirror plane which bisects the angle formed at the corner edge 15. In particular, the entire plaster profile 11 is designed symmetrically to this mirror plane.

The plaster profile 11 further comprises two legs 19 which each adjoin the corner section 13, namely a respective edge of the corner section 13 running parallel to the corner edge 15, and are firmly connected to the corner section 13 at the respective edge. The legs 19 are each to the respective surface section, that through the respective edge and the one closest to it Edge 17 is limited, aligned parallel so that they continue it flat.

The legs 19 are each formed by a wire structure which comprises three wires 21 which run parallel to the longitudinal direction L and are regularly spaced from one another. The edge of the corner section 13, to which the wire structure is attached, is spaced from the one of these wires 21 closest to it in a corresponding manner. The wires 21 parallel to the longitudinal direction L lie in one plane and are connected to one another by a further wire 23 which has a periodic spatial course within a further plane offset parallel to the above-mentioned plane. The wire structure lies entirely within these two planes, which thus define the flat design of the leg.

The course of the further wire 23 is sinusoidal. As a result, the further wire 23 crosses the wires 21 parallel to the longitudinal direction L several times in a regular sequence, being welded to the respective wire 21 at the crossing points. The vertices of the sinusoidal shape of the further wire 23 define the edges of the respective limb 19 with respect to its width transversely to the longitudinal direction L. The respective limb 19 is connected to a respective edge of the corner section 13 with one of these edges. For this purpose, every second vertex of the sinusoidal shape of the further wire 23 is welded to the respective edge of the corner section 13.

The two legs 19 are aligned at an angle of approximately 60 ° to one another. As a result, when the plaster profile 11 is arranged on a corner region of a component 25, where two surfaces of the component 25 meet at right angles, the corner edge 15 projects from this corner region (cf. Fig. 3 ). How far the corner edge 15 protrudes from the corner region of the component 25 depends on the angle between the two legs 19 and their respective width. the Corner edge 15 can be used as a pull-off edge for plastering the component 25, the thickness of the plaster layer being determined by how far the corner edge 15 protrudes. In principle, the two legs 19 can also be aligned at an angle of 90 ° to one another and then lie flat against the two surfaces of the component 25. The corner edge 15 can then, however, still protrude from the corner region of the component 25 due to the respective shape of the corner section 13, which in the present example is like a lantern roof.

Due to the wire structures from which the legs 19 are formed, plaster can simply penetrate through the legs 19 and largely fill the area between the plaster profile 11 and the component 25. In addition, the legs 19 of the plaster profile 11 are surrounded by the plaster in such a way that good interlocking of the plaster with the plaster profile 11 is guaranteed. The corner section 13, on the other hand, does not include a wire structure, but is formed from a sheet metal strip that is closed at least in some areas. This defines a smooth and precisely shaped corner in the area of the corner edge 15, which provides a reliable reference for plastering the corner area of the component 25.

That in the Figures 4 and 5 Plaster profile 11 shown and not claimed differs from that in FIG Figs. 1 to 3 shown not claimed plaster profile 11 at least substantially only by the formation of the corner portion 13. Because the corner portion 13 of the in the Figures 4 and 5 The plaster profile 11 shown is only bent over at one corner edge 15, but not additionally at other edges 17. At the corner edge 15, the corner section 13 is bent over by approximately 90 °, so that the corner section 13 thereby has two surface sections angled to one another. Since the legs 19, which are each formed at least essentially by a wire structure of interconnected wires 21, 23 and adjoin a respective surface section of the corner section 13, each extend parallel to the respective surface section, in the case of the in FIG Figures 4 and 5 Plaster profile 11 shown also the legs 19 at an angle aligned from about 90 ° to each other. In principle, however, the legs 19 can also enclose a different angle, for example approximately 60 °, with this plaster profile 11.

The ones in the Figures 6 and 7 The embodiment shown of a plaster profile 11 according to the invention largely corresponds to that in FIG Figs. 1 to 3 Plaster profile 11 shown and, in contrast, has only one additional reinforcement fabric 27. Both legs 19 of the plaster profile 11 each have such a reinforcing fabric 27. The reinforcement meshes 27 are each integrated into the wire structure of the respective leg 19 and each extend over the entire respective wire structure (even if they are in Fig. 6 are shown shortened in the longitudinal direction L). At least in the direction pointing away from the corner section 13, the reinforcing fabric 27 also extends beyond the wire structure, as shown. In this way, the reinforcement fabric 27 can widen the respective leg 19 transversely to the longitudinal direction L and provide an additional surface on which plaster can penetrate and surround the leg 19, so that additional anchoring of the plaster profile 11 is achieved. The reinforcing fabric 27 can in principle also protrude in the longitudinal direction L, on one side or on both sides, over the wire structure, in particular over the entire rest of the plaster profile 11. In the direction of the corner edge 15, however, the reinforcing fabric 27 preferably does not protrude beyond the wire structure. Thus, like the wire structure, the reinforcing fabric 27 does not extend over the corner section 13, in particular not over its corner edge 15. This is particularly important in the in Fig. 7 shown cross-sectional representation of the plaster profile 11 to recognize.

The reinforcement fabric 27 is in the Figures 6 and 7 The embodiment shown is integrated into the wire structure of a respective leg 19 in that it is arranged between different wires 21, 23 of the wire structure. Several wires 21 run on one side of the reinforcement fabric 27, while the at least one further wire 23 runs on the opposite side of the reinforcement fabric 27 runs. In this way, the reinforcement fabric 27 is clamped between the wires 21 on one side and the other wires 23 on the other side. The wires 21 on the one hand, which define a first plane through their course and / or their arrangement, and the at least one further wire 23 on the other side, which defines a second plane through its course and / or its arrangement, are included through the reinforcement fabric 27, namely through meshes of the reinforcement fabric 27, connected to one another. As a result, the reinforcing fabric 27 is, so to speak, caught between two layers of wires 21, 23 corresponding to the above-mentioned planes of the wire structure.

That in the Figures 8 and 9 Plaster profile 11 shown, which is not claimed, represents an alternative to the aforementioned embodiment according to the invention of forming a plaster profile 11 with a wire structure and reinforcing fabric 27 integrated therein. The way in which the reinforcing fabric 27 is integrated into the wire structure corresponds to that for the Figures 6 and 7 embodiment shown in the manner described. In contrast to the plaster profiles 11 of the unclaimed described above Figs. 1 to 5 as well as to the above-described plaster profile 11 of the invention Figures 6 and 7 shows that in the Figures 8 and 9 The plaster profile 11 shown, which is not claimed, has a single continuous wire structure which extends over the corner section 13 and thus also over the corner edge 15. The two legs 19 thus comprise different parts of the same wire structure. Furthermore, the corner section 13 also comprises a further part of this wire structure, as in particular in the cross-sectional illustration of FIG Fig. 9 can be seen. For this purpose, the wire structure, which is otherwise at least essentially flat and planar, is bent over by approximately 75 ° along the corner edge 15, whereby in principle other angles, for example 90 ° or 60 °, can also be expedient.

In addition, the corner section 13 has a cover 29 in the form of a corner strip which is placed on the wire structure at the corner edge 15. The cover 29 is made of plastic, but can also be made of metal or a composite material, and is used to reinforce the corner edge 15 and to define it precisely. In particular, the cover 29 can provide a pull-off edge for plastering the plaster profile 11.

As in the above-described embodiment of a plaster profile 11 according to the invention, the reinforcing fabric 27 is integrated into the wire structure in that it is caught between two layers of the wire structure. In the present case, however, the two layers are each formed not only by one, but by several wires 21 or several further wires 23, which each define a first or second plane of the wire structure. The wires 21 of one layer are aligned parallel to the longitudinal direction L, while the other wires 23 of the other layer have a sinusoidal periodic course and partially cross one another.

The respective wire structure with integrated reinforcement fabric 27 is produced by first arranging the wires 21 in relation to one another in a first plane, so that they form a first layer of the wire structure; then the reinforcement fabric 27 is arranged thereon, for example placed on it, parallel to the first plane; and then the further wires 23 are arranged on the opposite side of the reinforcing fabric 27 to the wires of the first layer, for example placed thereon, so that they lie in a second plane and in this way form a second layer of the wire structure. Finally, the wires 21 of the first layer are connected to the further wires 23 of the second layer through the reinforcing fabric 27, in particular welded. The layers and the reinforcement fabric 27 arranged between them are aligned parallel to one another. The wire structure can also have more than two layers, each of which can be formed in a corresponding manner. the Layers can also only comprise a single wire 21, 23, the course of this wire 21, 23 then (such as the aforementioned sinusoidal course) having directional components in two spatial dimensions and in this way defining the plane corresponding to the respective position.

A wire structure produced in the manner described for use in a plaster profile or some other building profile is initially flat and level, but can then, if necessary, be brought into a desired shape, in particular by bending. The ones in the Figures 8 and 9 The wire structure shown, for example, has been bent over in its center along the longitudinal direction L in order to thereby form the corner edge 15. In the case of a deformed wire structure, the wires 21, 23 of a respective layer of the wire structure are no longer located in a respective plane. When speaking of a plane defined by wires of the wire structure, in the case of deformed wire structures this is to be understood in relation to the undeformed wire structure in its flat and planar form.
