Abstract

A plastering strip (2) has a localizing area (LA) (10), a protective area (PA) (12), a reinforcing textural piece (RTP) (14) and an area (8) to plaster up to, which amounts to the whole main body of the strip, so that, outside this area, there are just the LA, the PA and, if required, the RTP.

Description

The invention relates to a plaster strip, which has a plastering area, a fixing area and a wegführenden, detachable protection area.

Such plaster strips are known in numerous designs. Example becomes on EP 0 318 045 B pointed out.

In most cases, the removable protection area was designed as a protective tab made of the material of the plaster molding (typically polyvinyl chloride), which was separated by kinking from the rest of the plasterboard. The separated protective flap must be disposed of properly. If one imagines a building with a large number of windows and one plastering strip at the top, left, right, bottom of each window frame, it is immediately obvious that waste must be disposed of in considerable quantities, which is also bulky and bulky in the accumulated state ,

The invention has the object of providing the plaster molding of the type mentioned in such a way that the elimination of the separated (after its use) protected area easier.

To solve this problem, the plaster molding is characterized in that the protected area consists essentially of verrottungsfähigem or biodegradable material.

The protection areas can either be collected after separation and transported to a refuse collection point; In this case, the improvement over the prior art is that it is not necessary to dispose of waste which requires special treatment, but the Waste such as household waste can be disposed of. Alternatively, you can easily leave the separated areas of protection on the property on which a building has been established, buried, for example, together with other uncritical construction waste (eg brick fragments). Because of the rotting ability, the separated areas of protection in the soil are decomposed within a reasonable amount of time without pollutants being introduced into the soil.

When building buildings today is the procedure in many cases: After the building walls are with window openings and door openings, window frames and in the door openings door frames are inserted and fixed there in the window openings. Before the construction is plastered, horizontal or vertical plaster moldings are attached to the top, left, right and bottom of the window frames and to the door frames at the top, left and right. In the case of conventional cleaning strips with protective flap, a plastic film could be glued to the protective straps to cover the window frame opening or the door frame opening. Also, in the plaster molding according to the invention such adhesion of a plastic film or other protective sheet is possible by sticking to the protection area of rotatable material, although the invention also provides an alternative way of protecting the window frame or the door frame from contamination, as will be explained below becomes. Thereafter, the building wall, for example, be first plastered on the outside, without having to work meticulously to prevent fouling of the window frame or door frame by plaster. The plaster is applied to the plastering area of the plastering strip. After the plaster has become sufficiently strong, you can optionally separate the protection area together with the glued foil or other flat material. Now, the plaster molding is a link between the end of the plaster and the window frame or door frame. This link is to avoid the formation of a gap between the end of the plaster and the window frame or door frame. Preferably, screed strips are formed so that they give a certain "elasticity" between the end of the plaster and the window frame or door frame. It is emphasized that on the described Manner can be worked with plaster strips both on the outside of a window frame or door frame and on the inside of a window frame or door frame at the transition to interior plaster.

If it is intended to work with the plaster strip according to the invention with the attachment of a protective sheet material to the protective area for covering the window frame opening or door frame opening, preferably a rotatable protective sheet material is used, particularly preferably an identical or similar material as in the protected area , (Plastic film is also because it is much easier to dispose of than plastic protective tabs). Alternatively, however, it is possible to work in such a way that the protective area of rotatable material is placed around the respective leg of the window frame or door frame and roughly fastened in this state. Then at least the window frame or door frame is secured in the implementation of plastering work from contamination, and you just have to be careful that no plaster as possible through the open window frame opening or door frame opening through inside in the building or when applying interior plaster is thrown out of the building to the outside. The latter possibility does not exist with conventional protective tabs. However, the protective area according to the invention essentially of rotting material can easily be chosen so wide that it allows the described laying around the respective leg of the window frame or door frame.

Preferably, the scope of the invention is constructed with paper. Paper is easily available in a version with sufficient strength (eg in the form of so-called wrapping paper, as it is used for wrapping packages). However, it is preferred to use a type of paper which is endowed with increased resistance to moisture, so that the paper does not become too tight under the effect of sprayed wet plaster. Papers with increased moisture resistance are well known, eg provided with suitable impregnations. There are such papers available that are verrottungs despite increased moisture resistance.

Another preferred option for the material of the protective area is to build up the protective area with flat material made of natural or renewable fibers, particularly preferably cellulose fibers, sisal fibers, hemp fibers or coconut fibers. These flat materials are inherently more resistant to moisture than unprepared paper. The fiber sheet may in particular be a nonwoven.

Another alternative is rotatable plastic film for the material of the protected area. This also applies to the above-mentioned protective sheet for the window opening or door opening.

For separability of the protection area can be a line of weakness, preferably a perforation, provide, along which the protection area can be separated by pulling it from the rest of the plaster strip. But you can also work without line of weakness / Perforationslinie and e.g. Provide that the protection area is simply cut off with a knife from the rest of the plastering strip. Furthermore, there is the possibility of lateral pullout, see below.

The protective area preferably has at least one adhesive surface in a partial zone remote from the plastering area, more preferably at the edge area there. This adhesive surface can be used in particular in order to adhere there the already mentioned protective sheet. But the adhesive surface can also be provided so that you can use them to attach the protection area after laying around the local leg of the window frame or door frame. On the market, rotting materials are available to produce an adhesive surface on the plastering area, e.g. like self-adhesive stamps.

The plastering area preferably has at least one limb which protrudes away from the window frame in the state of the plastering strip attached to a window frame or door frame. The leg can be positioned so that it is completely embedded in the applied plaster.

But there are also versions in which the leg or a leg is covered only on one side with plaster.

Preferably, a Armierungsgewebestück, preferably in the form of a plastic-coated fiberglass mesh, attached to the plaster molding. The Armierungsgewebestück is after the application of the plaster under the plaster surface, in most cases in turn attached by means of filler to the substrate. The reinforcing fabric piece improves the adhesion of the plaster to the substrate and ensures the permanent crack-free of the plaster.

Preferably, the fixing region comprises an adhesive strip, preferably a foam adhesive tape. The term "adhesive tape" also encompasses a strip-wise applied amount of adhesive. The design can be such that the adhesive strip, which adjoins the rest of the plastering strip on one side and can be adhered to the window frame or door frame on the other side, already constitutes the fixing region as such. It is emphasized, however, that there are alternative ways of forming the fixing region, in particular screwing and clamping in a gap between a thermal barrier coating and the window frame or door frame.

A preferred possibility of combining the protection area with the rest of the plastering strip is that the protective area is constructed with a flat material which is fastened with a border zone between the fixing area and the remaining plastering strip. So it uses the unification point between the fixing area and the rest of the plastering strip to attach there even the edge zone of the flat material for the protection area on the rest of the plastering strip.

This is particularly advantageous if, as preferred, the fixing region has an adhesive tape and if the transition between the adhesive strip and the remaining plaster strip to a first part bonding between the adhesive strip and the rest of the plastering strip and to a second part Zwischenfügung the edge zone of the sheet between the adhesive strip and the rest of the plastering strip is. The area ratio between said first part and said second part is designed so that on the one hand adhesive force of sufficient magnitude is produced between the adhesive strip and the remaining plastering strip and on the other hand the protection zone is fastened with sufficient strength to the remaining plastering strip.

In principle, the edge zone can end with a straight edge. However, it is preferred to form the edge zone with spaced edge recesses, wherein the edge recesses are preferably substantially part-circular. As a result of this embodiment, bonding strength between the adhesive strip and the remaining plastering strip as well as the fastening strength of the protective zone are brought into optimum harmony.

Preferably, the intermediate edge zone of the flat material has a size such that the flat material together with the edge zone can be separated from the rest of the plastering strip by pulling on the flat material. By means of this training can be done without perforation or other line of weakness in the sheet. It should be noted, however, that it is a possibility within the scope of the invention to provide a perforation line or other line of weakness at a location of the sheet material which is located between the adhesive strip and the remaining plastering strip.

Preferably, the interposed edge zone of the sheet makes up 5 to 30%, more preferably 5 to 20%, of the total area that would be bonding between the adhesive strip and the remaining plastering strip without intervening edge zone. By means of this surface portion can be particularly optimally ensure that on the one hand, the adhesive attachment adhesive / residual plaster board and adhesive tape / edge zone of the protective material is large enough and that on the other hand, the edge zone of the sheet can be sufficiently easily pulled out sideways, so are freed from the direct bonding with the adhesive tape can.

It is expressly pointed out that the aspect of the invention described in some of the preceding paragraphs, namely from "edge zone of the sheet material fastened between the fixing area and the remaining plastering strip", also without the measure described in the first paragraphs of the application rotting material "is technically feasible feasible. In particular, it is possible to use a protective area made of non-rotting plastic film and to separate it after use from the rest of the plastering strip.

If the protective area or the edge zone of the flat material (as is the case in particular with a number of types of plastic) consists of a material which makes no or only a slight adhesive bond with the adhesive strip, the aspect of the invention functions "edge zone of the flat material is between attached to the fixing area and the remaining grout "nevertheless. Then those areas of the edge zone that are located between the adhesive tape and the rest of the plastering strip are held primarily by "pinching" between the adhesive tape and the remaining plaster molding. In particular, in these cases, it may be advantageous if widen end regions of the edge zone behind the direct bonding between the adhesive strip and the rest of the plastering strip, so that there is virtually a (more or less pronounced) positive retention of the edge zone.

• Fig. 1 eine Anputzleiste im Querschnitt;
• Fig. 2 und 3 mehrere Möglichkeiten der Befestigung des Schutzbereich-Flachmaterials an der Anputzleiste, und zwar mit Betrachtungsrichtung gemäß Pfeil P in Fig. 1 und bei weg genommenem Befestigungsbereich, wobei der Zeichnungsmaßstab deutlich größer als bei Fig. 1 ist.

The invention and preferred developments of the invention are explained in more detail with reference to exemplary embodiments illustrated in the drawings. It shows:

• Fig. 1 a plastering strip in cross section;
• FIGS. 2 and 3 several ways of attaching the protective area flat material to the plastering strip, with viewing direction according to arrow P in Fig. 1 and with taken away mounting area, the drawing scale is much larger than at Fig. 1 is.

For the sake of brevity, the term "bar" instead of "bar bar" is used throughout.

In Fig. 1 a bar 2 is drawn in attached to a leg of a window frame 4 state. Fig. 1 is a horizontal section of a building wall 6 (there the so-called soffit in the region of a window opening). Arrow A indicates the direction to the outside of the building, arrow I indicates the direction to the inside of the building.

The strip 2 has the following main components: plastering area 8, fixing area 10, protective area 12 and reinforcement fabric piece 14. In many embodiments, the plastering area 8 makes up the entire main body of the strip, so that apart from the plastering area 8 only the fixing area 10, the protection area 12 and - If desired - the Armierungsgewebestück 14 are present. It is emphasized, however, that there are strips 2 according to the invention in which one or more additional constituents are present, e.g. a base portion, to which the fixing portion 10 is fixed, between the plastering portion 8 and the fixing portion 10.

In the illustrated embodiment applies: The Anputzbereich 8 is by a (mounted on the window frame 4 state parallel to the outer front surface of the frame 4 extending) foot 16 and a right angle. realized by the foot 16 in the direction of the arrow A protruding leg 18. This in Fig. 1 right end of the foot 16 tapers towards the end. The Armierungsgewebestück 14 is secured by ultrasonic welding (welding strand 20) on the leg 18. The fixing portion 10 is realized by a double-sided foam adhesive tape (alternatively, other adhesive tape). The protective area 12 is realized by a section of high-strength paper impregnated to increase the moisture resistance or by a flat material constructed of fibers, in particular as a nonwoven, alternatively by a plastic film see second aspect of the invention.

With broken lines is in Fig. 1 a plate-shaped thermal insulation 22 located, which is mounted in many cases on the soffit surface of the window opening. The thermal insulation 22 is in Fig. 1 trimmed drawing-down to increase the clarity of the drawing; In addition, a plaster layer 24 is located, which fills a plaster receiving space 26 at the bar 2, so that in the finished plastered state of the plastering area 8 of the strip 2 practically nothing more you can see.

1. (a) leicht rechts von dem in Fig. 1 rechten Ende des Anputzbereiches 8;
2. (b) ziemlich exakt an dem in Fig. 1 rechten Ende des Anputzbereiches 8 (besonders bequeme Abreißbarkeit);
3. (c) ein wenig in Fig. 1 nach links versetzt gegenüber dem rechten Ende des Anputzbereiches 8 (ergibt quasi-unsichtbare Abreißlinie nach dem Abreißen);
4. (d) in Fig. 1 noch weiter nach links versetzt gegenüber dem rechten Ende des Anputzbereiches 8, so dass sich die Stelle S in der Zone zwischen der in Fig. 1 oberen Fläche des Schaumstoffklebebands 10 und der in Fig. 1 unteren Oberfläche des Fußes 16 des Putzbereiches 8 befindet.

In the simplest case, the material of the protective region 12 has a perforation line or other type of weakening line at the point indicated by the arrow S. The location S may be:

1. (a) slightly to the right of the in Fig. 1 right end of the plastering area 8;
2. (b) quite exactly at the in Fig. 1 right end of surface area 8 (especially easy tear-off);
3. (c) a little in Fig. 1 offset to the left with respect to the right end of the plastering area 8 (results in a quasi-invisible tear-off line after being torn off);
4. (d) in Fig. 1 further offset to the left opposite the right end of the plastering area 8, so that the point S in the zone between the in Fig. 1 upper surface of the foam adhesive tape 10 and the in Fig. 1 lower surface of the foot 16 of the plaster area 8 is located.

At the in Fig. 1 right edge area of the protection area 12 are an in Fig. 1 upper adhesive surface 28 and / or in Fig. 1 lower adhesive surface 30 is provided. Both adhesive surfaces are covered in the delivery state of the bar 2 with a not marked, easily peelable cover. The lower adhesive surface 30 serves, after the laying around of the protective area 12 (clockwise in, so to speak, in FIG Fig. 1 ) to set the drawn leg of the window frame 4, the edge region of the protective area 12 on the window frame 4. Alternatively, one can accomplish this attachment by means of separate tape "from the role". The upper adhesive surface 28 serves to protect a protective sheet material, the window opening concealing the four protection areas 12 of four strips 2 (namely, top, left, right, bottom).

The FIGS. 2 and 3 illustrate some of very many existing possibilities of forming the left edge zone 32 of the sheet in the drawings, with which the protective region 12 is formed. One recognizes in the FIGS. 2 and 3 the left edge 34 of the Anputzbereiches 8 and - drawn in a broken line, because behind the flat material 12 befindlich - the right edge 36 of the Anputzbereiches 8 in a strong broken line. A perforation line or other weakening line 38 is indicated by a broken line. In the embodiments according to FIGS. 2 and 3 It is primarily about the formation of the edge zone 32 such that it is fastened by adhesive fastening of the fixing region 10, in particular of the foam tape 10, to the rest of the strip 2 at the same time with the bar 2.

Fig. 2 illustrates on the one hand the possibility that the edge zone 32 is substantially the same width as the foot 16 of the bar 2. The edge zone 32, however, has large circular punch openings 40 through which the bonding between band 10 and foot 16 can take place.

On the other hand, indicated by a dotted line 46 that, alternatively, the edge zone 32 can be made significantly less wide than the foot 16; instead of the all around bounded openings 40 now only more than semi-circular recesses 42 are present.

In the embodiment according to Fig. 3 extends the sheet 12 with a peripheral zone 32 between the belt 10 and the foot 16, in the (in Fig. 3 measured from left to right) width occupies only a fraction of the width of the foot 16 and the band 10. The edge zone 32 is formed with part-circular recesses 42, wherein between each two adjacent recesses 42 each have a tongue 44 is located. To illustrate, a part of the band 10 is drawn, which is glued to the structure of remaining plastering strip and edge zone 32 of the sheet material or protective area 12. By pulling on the flat material 12 to the right in Fig. 3 For example, the edge zone 32 may be pulled out of the "gap" between the belt 10 and the foot 16 without the need for a line of perforation or other line of weakness.
