PLASTER PROFILE

Description

[0001] The invention relates to a plaster profile with an elongated profile body which is intended for fastening to a wall section to be plastered and has an edge section which comprises a flat strip which is bent along a corner edge and is designed at least in regions for the application of a plaster layer.

[0002] US 2002 / 073639 A1 discloses a drywall profile comprising a metallic edge portion with a plasterable strip attached thereto.

[0003] It is an object of the invention to provide a plaster profile of the type mentioned at the outset which enables good adhesion of plaster to the plaster leg or to another section designed for the application of a plaster layer, prevents plaster from falling through, trickling down or falling off using simple means and is versatile in its use.

[0004] The problem is solved by a plaster profile having the features of claim 1. The plaster profile can in particular be an edge profile.

[0005] Edge profiles, especially corner profiles, are used to create clean edges when plastering walls. However, applying plaster can be particularly difficult in the corner area, as a relatively large amount of plaster must adhere to a small surface area. Therefore, a plastic cover is often attached to the corner edge. This protrudes from the corner edge and is covered with little or no plaster. This plastic cover can also provide corrosion protection, but it involves undesirable additional costs.

[0006] According to the invention, a plasterable film is applied to the edge section.

[0007] The plasterable film provides a suitable adhesive substrate, ensuring reliable adhesion of the plaster even in the corner area, even without openings. This advantageously eliminates the need for a plastic cover.

[0008] According to the invention, the edge section is rounded and the plasterable film is not applied directly to the edge section, but to a plastic head which in turn is applied to the edge section.

[0009] The edge section is preferably completely closed. Since the edge section is also designed, at least in some areas, for the application of a plaster layer, it corresponds to the plaster leg of the plaster profiles described below, in particular its completely closed surface section.

[0010] The corner edge can be aligned parallel to the longitudinal direction of the profile body.

[0011] The plasterable film can be glued in particular to the edge section.

[0012] Preferably, the plasterable film extends over the corner edge. This provides an improved adhesive surface on both sides of the corner edge.

[0013] The plasterable film can be designed as described below. Furthermore, advantageous configurations of the profile body, which are described below in connection with an overhang profile, can also be advantageous for an edge profile. In particular: the film can cover at least the aforementioned flat strip or the entire edge section over its entire surface; at least the aforementioned flat strip or the entire edge section can be at least substantially smooth; the profile body can be one-piece; the profile body can be made of stainless steel; the plasterable film can be designed as a self-adhesive film; and / or the plasterable film can comprise at least one fleece layer.

[0014] The disclosure also relates to a plaster profile, in particular an overhang profile or an edge profile, with an elongated profile body which is provided for fastening to a wall section to be plastered and which has at least one flat section, in particular a plaster leg, which is designed for applying a plaster layer.

[0015] Such plaster profiles are generally used to create precise plaster finishes or plaster boundaries in construction. They come in a wide variety of designs, for example as overhang profiles, edge profiles, connection profiles, end profiles, plaster gauges, dimpled sheet profiles, expansion and movement joint profiles, reveal connection profiles, or base profiles. To ensure that the plaster to be applied adheres reliably to the plaster leg, the plaster leg can be provided with perforations or profiles or be designed as a wire mesh. This allows the plaster to claw into or onto the profile, but is associated with comparatively high production costs. A particular problem is the permeability of perforated or wire mesh plaster legs, insofar as the applied plaster can trickle down or fall off the back of the plaster leg.This problem occurs particularly with horizontally applied overhang profiles, where there is a cavity between the plaster leg and the wall. To catch any dripping or falling plaster, a plastic profile or plastic cover can be attached to the plaster leg, but this further increases production costs and limits the application location due to the specified dimensions of the plastic profile or cover.

[0016] According to the disclosure, the plaster profile comprises an elongated profile body which is provided for fastening to a wall section to be plastered and which has at least one flat plaster leg which is designed for applying a plaster layer, wherein the at least one flat plaster leg has a continuously closed surface section and wherein a plasterable film is applied to the continuously closed surface section.

[0017] The closed surface section of the plaster leg therefore has no perforations or recesses. Therefore, the applied plaster cannot penetrate the plaster leg and run onto another component or to the floor. Accordingly, a plastic profile or plastic cover to collect the plaster is no longer necessary, which enables more flexible use of the plaster profile in combination with various additional components such as capping strips and flashings. A plasterable film within the meaning of the present disclosure is understood to mean a film that is specifically designed for plaster application, i.e., is designed as an adhesive substrate for plaster. Reliable adhesion of the plaster is thus guaranteed despite the lack of perforations because the plasterable film provides a suitable adhesive substrate.The plasterable film can be a plaster base film, such as that used to seal connecting joints.

[0018] The plasterable film can cover the plaster leg at least substantially over its entire surface in order to provide the largest possible adhesive surface.

[0019] Preferably, the continuously closed surface section is at least substantially smooth. This allows for simple production because no work steps for roughening or structuring the surface of the plaster leg are required. Furthermore, the plasterable film is easier to apply to a smooth surface.

[0020] The profile body can be made of one piece. This allows for particularly simple and cost-effective production. For example, the profile body can be designed as a stamped and bent part, particularly made of sheet metal.

[0021] The profile body is preferably made of stainless steel. This prevents corrosion of the profile body, which is particularly important near the base, where exposure to moisture, snow, and road salt is more likely. In principle, the profile body could also be made of a metal other than stainless steel, plastic, or another corrosion-resistant material.

[0022] According to one variant, the plasterable film is glued to the plaster leg. This allows for particularly simple installation. Gluing it to a continuous, smooth surface is particularly advantageous.

[0023] The plasterable film can be designed as a self-adhesive film. This means that the plasterable film can include an adhesive layer. This eliminates the need for a separate application of adhesive to the plaster leg during production.

[0024] According to one variant, the plasterable film comprises at least one nonwoven layer. The fibers contained in the nonwoven layer provide a large and irregular surface and facilitate the adhesion of plaster. The plasterable film can generally comprise a fiber material, a woven fabric, a knitted fabric, or the like.

[0025] According to one variant, the profile body has a contact surface for applying the plaster profile to the wall section to be plastered, wherein the at least one flat plaster leg extends in an overhang plane that is offset from the contact surface, in particular offset parallel to it. Plaster profiles designed in this way are used, for example, as overhang profiles or metal connection profiles. The plaster leg can at least partially cover a wall-side connection sheet, a capping strip, or the like. With horizontally mounted plaster profiles with an overhanging and perforated plaster leg, the problem of plaster penetrating and falling down occurs particularly strongly. Due to the continuously closed surface section, falling plaster is not to be expected with a plaster profile according to the disclosure.The overhang plane may be offset from the contact surface by an offset of at least 3 mm and at most 30 mm, preferably of at least 5 mm and at most 15 mm.

[0026] The contact surface can be formed on a flat base leg of the plaster profile, which is provided with perforations. The flat base leg itself can be designed for plastering and can be screwed to a structural element such as a wall or attached with mortar. Since there is generally no risk of plaster running or falling off, the perforations are provided to improve the plaster's grip.

[0027] A special variant provides for the plaster profile to include a flat finishing strip, which is arranged adjacent to the plaster leg and extends perpendicular to it. Such a finishing strip creates a precise and visually appealing finish to the plaster surface. A plasterable film can also be applied to the finishing strip. The finishing strip can be formed by one or more bent sections of the profile body, which makes it particularly easy to manufacture.

[0028] Preferably, the end strip is completely closed. This prevents plaster from seeping through the end strip without requiring a plastic cover.

[0029] Furthermore, according to a further variant, the end web can comprise two layers formed by respective bending. In order to be continuously closed, it may be sufficient if one overlap of the two layers is continuously closed. Preferably, at least one of the layers is continuously closed, while the other layer can have openings. In particular, the layer facing the plaster layer to be applied can be provided with a perforation. Such a perforation can serve to further entangle the plaster in the profile. The other layer is then preferably continuously closed.

[0030] Further developments of the invention can also be found in the dependent claims, the description and the attached drawing.

[0031] The invention is described below by way of example with reference to the drawing. Fig. 1 shows a plaster profile not belonging to the invention with a plaster leg to which a plasterable film is applied. Fig. 2 shows the plaster profile according to Fig. 1 without the plasterable film. Fig. 3 is a side view of the Fig. 2 Fig. 4 is a cross-sectional view of a further plaster profile not belonging to the invention. Fig. 5 is a cross-sectional view of yet another plaster profile not belonging to the invention. Fig. 6 is a cross-sectional view of a plaster profile designed according to an embodiment of the invention.

[0032] The Fig. 1-3 The plaster profile 11 shown comprises a one-piece profile body 12 which extends in a longitudinal direction 13. In Fig. 1 and 2The plaster profile 11 is shown in abbreviated form for clarity. In fact, a plaster profile 11 according to the disclosure can have a significantly larger length-to-width ratio. The profile body 12 has a base leg 17 and a plaster leg 19, each of which is flat and extends in the longitudinal direction 13. The terms "base leg" and "plaster leg," which serve to distinguish the legs, are not intended to exclude the possibility that the base leg 17 is also plastered and is suitably designed for this purpose (see below).

[0033] The profile body 12 is manufactured by bending, edging, punching, and, if necessary, stretching from a flat metal strip, preferably made of stainless steel. For example, the metal strip can be 0.5 mm thick. The base leg 17 and the plaster leg 19 are each single-layer and flat. The base leg 17 is intended for attachment to a building structure. Fig. 1 The rear side of the base leg 17 facing away from the viewer forms a flat contact surface 21 for this purpose. As shown, the base leg 17 to be plastered is provided with openings 22 for plaster claws.

[0034] The plaster profile 11 shown is designed as an overhang profile. Accordingly, the plaster leg 19 extends as shown in particular in Fig. 3recognizable in an overhang plane 23, which runs parallel to the contact surface 21 and is offset from it. However, the overhang plane 23 could also not run parallel to the contact surface 21. In a direction pointing away from the base leg 17, a first closing web 25 adjoins the plaster leg 19. The first closing web 25 is two-layered, with the web layer 27 facing the base leg 17 being provided with a perforation 29, while the other web layer 30 forms a continuously closed surface section. The first closing web 25 has a plaster edge 26, which can be used in a basically known manner for smoothing during plaster application.

[0035] In a direction away from the plaster leg 19, a second end web 31 adjoins the base leg 17. Furthermore, a connecting web 33 extends between the base leg 17 and the plaster leg 19, through which the offset between the contact surface 21 and the overhang plane 23 is created.

[0036] As in Fig. 2 As can be seen, the cleaning leg 19 forms a continuously closed surface section 35, thus having no openings or the like. Fig. 1A plasterable film 37 of the plaster profile 11 is shown, which is applied essentially over its entire surface to the continuously closed surface section 35 of the plaster leg 19, preferably by gluing. In particular, the plasterable film 37 can be self-adhesive, i.e., comprise an adhesive layer, although this is not visible in the figures. Furthermore, in the present example, the plasterable film 37 comprises a nonwoven layer, e.g., made of a fiber material, which is also not visible in detail. However, other materials are also possible. The thickness of the plasterable film 37 can, for example, be approximately 3 mm.

[0037] Fig. 3shows a plaster profile 11 in an assembled and plastered state. The base leg 17 is attached to the wall 39 of a building by means of screws 40. However, an air gap or cavity 45 exists between the plaster leg 19 and the wall 39. This means that the plaster leg 19 forms an overhanging leg. As shown, a protective component 47, such as a capping strip, a flashing, a dimpled sheet, or the like, attached to the wall 39, protrudes into the cavity 45.

[0038] The base leg 17 and the plaster leg 19 of the plaster profile 11 are covered with a plaster layer 51, which ends at the first end web 25. The plaster layer 51 ideally comprises a fabric-reinforced plaster layer 53. It has been shown that the provision of the additional fabric-reinforced plaster layer 53 stabilizes the plaster layer as a whole and minimizes the risk of cracking in the plaster layer 51 when forces are applied to the plaster profile 11. In principle, the plaster layer 51 can comprise several individual layers.

[0039] Although no holes are provided on the plaster leg 19 for the plaster to adhere, the plaster layer 51 adheres well to the plaster leg 19 because the plasterable film 37 provides a favorable adhesive base. The absence of any perforations in the plaster leg 19 prevents unwanted plaster falling through the cavity 45.

[0040] In principle, the base leg 17 can also be attached to the wall 39 using setting mortar. A parallel offset of the plaster leg 19 relative to the base leg 17 is not necessary in this case, because the cavity 45 is created by the setting mortar. Furthermore, a plasterable film could also be provided on the base leg 17 and / or the first end web 25.

[0041] The Fig. 4 The plaster profile 11' shown comprises, like the previously described plaster profile 11, a one-piece elongated profile body 12', preferably made of stainless steel.

[0042] The longitudinal direction 13 runs perpendicular to the plane of the sheet. In contrast to the Fig. 1 to 3 The overhang profile shown is the one in Fig. 4The plaster profile 11' shown is designed as an edge profile. Accordingly, the profile body 12' has an edge section 61. This is formed by a flat strip 63 being bent along a corner edge 65 running parallel to the longitudinal direction 13, by 90° in the example shown, but other angles are also possible.

[0043] A plasterable film 37 is applied to the edge portion 61, preferably by gluing. The plasterable film 37 may comprise an adhesive layer and at least one nonwoven layer. As shown, the plasterable film 37 extends beyond the corner edge 65.

[0044] The plasterable film 37 facilitates the plastering of the plaster profile 11'. It is not necessary to provide the edge section 61 with perforations. Accordingly, the edge section 61 preferably forms a continuously closed surface section. The plasterable film 37 also acts as corrosion protection.

[0045] The Fig. 5 The plaster profile 11" shown is like the one in Fig. 4The plaster profile 11' shown is designed as an edge profile. The edge section 61, which forms a continuously closed surface section, is designed here as a roof-like profile head, to which two legs 67 are connected. As a result, the corner edge 65 protrudes comparatively further. The plasterable film 37 is applied, as shown, to the edge section 61 designed as a roof-like profile head. Thus, the high metal content of the roof-like profile head does not lead to adhesion problems. The plasterable film 37 does not have to be limited to the edge section 61, but can also extend from there to at least a part of one or both legs 67 in order to improve their respective plasterability, at least in some areas. For improved plasterability, the legs 67 can also be perforated, at least in some areas, e.g., designed as expanded metal. Fig. 5The plaster profile 11" shown is particularly suitable for exterior plastering.

[0046] In Fig. 6 Another plaster profile 11‴ designed as an edge profile is shown, which is designed according to an embodiment of the invention. This has, similar to the plaster profile 11" according to Fig. 5a protruding edge portion 61. In contrast, however, the edge portion 61 is rounded. In this embodiment, the corner edge 65 thus has a comparatively large radius of curvature. Furthermore, the plasterable film 37 is not applied directly to the edge portion 61, but rather to a plastic head 68, which in turn is applied to the edge portion 61. The plasterable film 37 is therefore applied indirectly to the edge portion 61 of the multi-component profile body 12'. The plastic head 68 is designed as a plastic strip which extends in the longitudinal direction 13 and can in particular be plugged onto the edge portion 61. The plastic head 68 is preferably made of polyvinyl chloride.

[0047] A plasterable film can be advantageous for many types of plaster profiles. However, the advantages of the invention are particularly evident for an overhang profile or an edge profile as shown in the figures. List of reference symbols:
