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

Glazing strip with protection area separable.

The invention relates to a ribbon for plastering, which presents a plastering area, an area of support and a separable protection area that moves away from the same.

The slats for plastering of this type are They know in numerous configurations. Illustratively, it indicates document EP 0 318 045 B.

In most cases, the separable protection area as protection flange of the lath material for plastering (typically polychloride vinyl), which could be separated from the remaining slat by bending. The separate protection flange must be discard properly. When a building is conceived with a multitude of windows and, respectively, a slat for plastering  up, to the left, to the right and down in each frame of window, it is immediately obvious that in this case you have to discard waste in a considerable amount that, in addition to that, bulky and bulky in the piled up state.

The invention is based on the objective of set the lath for plastering, of the type that has been mentioned at the beginning, so that it is done more simple removal of the separate protection area (after its use).

For the resolution of that objective, characterizes the lath for plastering because the area of protection consists essentially of a degradable material or biodegradable.

Protection areas can be collected after separation and transported to a collection point of trash; in this case, the improvement with respect to the state of the art is that you don't have to dispose of waste a special treatment is necessary, but the Waste as household waste. Alternatively, the areas of separate protection can remain without problem on the plot on which a building has been built, for example, to bury together with other harmless construction waste (for example, brick fragments). Due to the ability to degrade, it break down the separate protection areas on the ground within a foreseeable time, without in this case substances are introduced harmful on earth.

Today, during the construction of buildings We proceed in many cases as follows: after place the building walls with window openings and door openings, the window openings are inserted window frames and, in the door openings, the fences of door and look at that place. Before the construction, look at the window frames above, to the left, right and down and, in the door fences, up, left and right, horizontal or vertical slats for plastering. In the case of slats for plastering conventional with protection flange could adhere a plastic sheet, for covering the openings of the window frames or door fence openings, in the protection flanges. Also in the case of the ribbon for plastering according to the invention an adhesion of this type of a plastic sheet or other flat material of adhesion protection in the protection area of a material degradable, like the invention also offers a alternative possibility of protecting the window frame or door frame against dirt, as will be explained to continuation. After that, the wall of the wall can be plastered building, for example, first, on the outer side, without you have to work precisely, to avoid a fouling of window frames or door frames by plastering dough Plaster mass is applied until it reaches the plating area of the lath for plastering. After if the plaster has solidified sufficiently, it can be separated the protection area, in a given case, together with the sheet adhered or other flat material. Now, the bar for plastering represents a link between the end of the plaster and the frame of Window or door frame. This link should avoid formation of a gap between the end of the plaster and the frame of Window or door frame. Preferably, the slats for plastering so that they give a certain "elasticity" between the end of the plaster and the frame of Window or door frame. It is emphasized that, in the way described, you can work with slats for plastering, both on the outer side of a window frame or a door frame as on the inner side of a window frame or a door frame in the transition to an interior plaster.

When you should work with the bar to plastering according to the invention, with the placement of a flat protection material in the protection area for the covering of the window frame opening or the opening of the door fence, preferably a flat material of degradable protection, particularly preferably, a same or similar material as in the protection area. (Too it can be a plastic sheet, since it can be discarded much easier than the protection flanges of plastic). However, alternatively, it is possible to work in such so that the protection area of degradable material is placed around the corresponding branch of the window frame or door frame and, in this state, it is fixed to it inaccurate Then, at least the window frame is protected or the door frame, during the execution of the work of plastering, against fouling and must be taken into account only that, if possible, no plaster mass is released at through the open window frame opening or opening from the door frame inside the building or, during the application of an interior plaster, towards the outside of the building. The possibility mentioned above does not exist in the case of flanges Conventional protection However, the protection area of according to the invention essentially a degradable material is you can select without problems so wide that it allows placement that has been described around the corresponding branch of the frame of Window or door frame. Preferably, the area of Protection according to the invention is structured with paper. He paper can be obtained without problems in one embodiment with a sufficient firmness (for example, by way of the so-called paper of pack, as used to wrap packages). However, it you prefer to use a type of paper that is provided with a increased resistance against moisture, so that the paper with the wet plaster effect splashed on it do not do Too little firm. Papers with a increased moisture resistance, for example, provided with a properly impregnated. Papers of this type are obtained which, despite of increased resistance to moisture, they are degradable.

An additional preferred possibility for the protection area material consists of structuring the area of protection with a flat material of natural or renewable fibers, particularly preferably, cellulose fibers, fibers of sisal, hemp fibers or coconut fibers. These flat materials of by themselves they are more resistant against moisture than non-paper prepared. Particularly, the flat fiber material can be a non-woven fabric.

An additional alternative is a sheet of degradable plastic for the protection area material. This It is also valid for flat protection material, which has been mentioned above, for window opening or opening Door

In order to separate the protection area, it can provide a weakening line, preferably a drilling line, along which it can be separated from the slat for remaining plastering the protection area by traction in it. However, you can also work without weakening line / perforation line and, for example, provide that the protection area is simply cut from the bar to remaining plastering with a knife. In addition to that, there is the possibility of being able to be extracted laterally, see continuation.

Preferably, the protection area has in a partial area away from the area of plastering, so particularly preferred, in the edge area at that location, at less an adhesion surface. This adhesion surface can particularly used to adhere the flat material there of protection that has already been mentioned. However, the surface of adhesion can be provided in such a way that it can be used for fixing the protection area after placement around the branch in that place of the window frame or frame Door Degradable materials can be obtained in the market for the production of an adhesion surface over the area of plastering, for example, as self-adhesive stamps.

Preferably, the area of plastering it has at least one protruding branch, in the state placed in a window frame or a door frame, from the slat for plastering away from the window frame. The branch it can be located so that it is completely embedded in the plastering applied.

However, there are also embodiments in the that the branch or a branch is covered only on one side with mass of plaster.

Preferably, it is fixed on the bar for plastering a piece of armor fabric, preferably in shape of a fiberglass grid covered with plastic. The piece of weave fabric is placed after the application of plastered below the surface of the plaster, in most cases, fixed in turn at the bottom by means of dough to plaster. The piece of weave fabric improves the adhesion of the plaster in the bottom and guarantees the plaster without cracks.

Preferably, the holding area has an adhesive strip, preferably a foam adhesive tape. The term "adhesive strip" also comprises an amount of strip applied adhesive. The realization can be so that the adhesive strip, which joins the slat on one side for remaining plastering and can be adhered on the other side in the window frame or door frame, already represent the clamping area However, it is emphasized that there are ways Clamping area configuration alternatives, particularly, screwing and immobilization in a slit between a layer of thermal insulation and the window frame or the door frame.

A preferred possibility of unification of the protection area with remaining slat for plastering is that the protection area is structured with a flat material that is fixed in an edge area between the area clamping and the remaining slat. Therefore, it use the unification site between the clamping area and the slat for remaining plastering, to fix the area of  edge of the flat material for the protection area in the slat for remaining plastering.

This is configured particularly advantageous when, as preferred, the clamping area has an adhesive strip and when the transition between the adhesive strip and the bar for remaining plastering is, in the first part, an adhesion between the adhesive strip and the plating strip remaining and, in a second part, an intermediate fitting of the edge area of the flat material between the adhesive strip and the slat for remaining plastering. The proportion of surface between the first part mentioned and the second part mentioned are dimensions so that, on the one hand, a force of adhesion with a sufficient magnitude between the adhesive strip and the slat for remaining plastering and that, on the other hand, the area of protection is fixed with sufficient strength on the bar to remaining plastering.

In principle, the edge zone may end With a straight song. However, it is preferred to configure the zone of edge with separating edge recesses, where, preferably, the edge recesses have essentially a partial circle shape. This configuration is harmonized with Optimally adhesion strength between the adhesive strip and the slat for remaining plastering as well as fixing fastness of the protection area.

Preferably, the embedded edge area of intermediate shape of the flat material has a size such that the flat material can be separated, together with the edge area, from the slat for remaining plaster, if the flat material is pulled. Through this configuration you can do without the line of perforation or other line of weakening in the flat material. Without However, it is indicated that a possibility that falls within the framework of the invention consists in providing a perforation line or another line of weakening at a flat material site, which place between the adhesive strip and the slat for plastering remaining

Preferably, the embedded edge area of intermediate form of the flat material constitutes 5 to 30% of particularly preferred form, from 5 to 20%, of the entire surface that, without any edge zone embedded in an intermediate way would be an adhesion between the adhesive strip and the plating strip remaining Through this proportion of surface you can ensure particularly optimally that, on the one hand, the Adhesion fixation of remaining adhesive strip / plastered strip, as well as adhesive strip / edge area of the material protection is large enough and that, on the other hand, the area edge of the flat material can be extracted laterally simple enough, in fact, can be released from adhesion Direct with the adhesive strip.

It is expressly emphasized that the appearance of the invention described in some preceding paragraphs, in fact, to from "edge area of the flat material is fixed between the clamping area and remaining slat for plastering ", is can perform technically reasonably also without the measure described in the first paragraphs of the application "area of protection consists essentially of a degradable material. " in this way, a protection area can be used particularly also from a non-degradable plastic sheet and separate it after use of the remaining slat.

When the protection area or the edge area of the flat material (as is the case particularly in various types of plastic) consists of a material that does not get any or only a reduced adhesion bond with the adhesive strip, however, the aspect of the invention works "edge zone of the flat material is fixed between the clamping area and the slat for remaining plastering. "Then, the areas of the edge area between the adhesive strip and the slat for remaining plastering they are held first by "immobilization" between the adhesive strip and the lath for remaining plastering. Particularly, in these cases it can be advantageous that the terminal areas of the edge area widen behind the direct adhesion sites between the adhesive strip and the bar for remaining plastering, so that in that place, so to speak, a support with form drag takes place (more or less intense marking) of the border area.

The invention and preferred improvements of The invention is explained in more detail below by Examples of embodiment represented graphically. Be sample:

In Figure 1, a slat for plastering in a cross section;

In Figures 2 and 3, several possibilities of fixing the flat material of the protection area on the slat for plastering and, in fact, with the observation direction of according to arrow P in Figure 1 and, with the fixing area withdrawal, the scale of the drawing being expressly greater than in the Figure 1.

For reasons of brevity it refers to Continuously continue to a "ribbon" instead of a "ribbon for plastering".

In Figure 1 a ribbon 2 is drawn on the state fixed on a branch of a window frame 4. Figure 1 is a horizontal cut of a wall of a building 6 (in that place, the called windowsill in the area of a window opening). With the arrow A indicates the direction towards the outer side of the building, with the arrow I the direction towards the inner side of the building.

Ribbon 2 has the following components Main: plastering area 8, clamping area 10, area of protection 12 and piece of armor fabric 14. In many embodiments, the area of plastering 8 constitutes the entire body main of the ribbon, so that, apart from the area of plastering 8, there is already only the holding area 10, the area of protection 12 and -when desired- the piece of armor fabric 14. However, it is emphasized that there are slats 2 according to the invention, in which there are one or more components additional, for example, a basic area, in which the clamping area 10, between the plastering area 8 and the area of clamping 10.

In the example of embodiment shown it is valid: the area of plastering 8 is made by a foot 16 (which, in the been placed in window frame 4, it has a path parallel to the external front surface of the frame 4) and a branch 18 protruding rectangular outward from foot 16 in direction of the arrow A. The right end in Figure 1 of the foot 16 decreases towards the end. The piece of armor fabric 14 is fixed by ultrasonic welding (welding section 20) on the branch 18. The holding area 10 is made of a tape double-sided foam adhesive (alternatively, another strip adhesive). The protection area 12 is made by a section of a strong role impregnated for increased resistance to moisture or, by a flat material structured by tapes, particularly, nonwoven fabric, alternatively, by a plastic sheet, see the second aspect of the invention.

In Figure 1 it is drawn with lines uninterrupted thermal insulation 22 in the form of a plate that, in many cases, it is placed on the surface of the windowsill of the window opening. Thermal insulation 22 is trimmed in Figure 1 at the bottom, due to the drawing technique, to increase the clarity of the drawing; normally isolation thermal 22 reaches just to the front side of foot 16 of the slat. In addition to that, a plaster layer 24 is drawn that fills in lath 2 a plastering accommodation space 26, so that, in the finished plastering state of the plastering area 8, You can hardly see anything on the ribbon2.

The material of the protection area 12 has in the simplest case a perforation line or a line of weakening of another type at the site indicated by the arrow S. The S site can be located:

(to)

slightly to the right of the end right in Figure 1 of the area of plastering 8;

(b)

from fairly accurate shape at the right end in Figure 1 of the area of plastering 8 (particularly comfortable tearing);

(C)

shifted a little to the left in Figure 1 with respect to the right end of the area of plastering 8 (gives a tearing line, so to speak, invisible after tearing);

(d)

shifted further to the left in Figure 1 with respect to the right end of the area of plastering 8, so that site S is located in the area between the upper surface in Figure 1 of the foam adhesive tape 10 and the bottom surface in Figure 1 of foot 16 of the area of plastering 8.

In the right edge area in Figure 1 of the protection area 12 an adhesion surface 28 is provided upper in Figure 1 and / or a lower adhesion surface 30 in Figure 1. Both adhesion surfaces are drawn on the delivery status of ribbon 2 with a cover sheet that You can easily remove, which has not been drawn. The surface of lower adhesion 30 serves to hold, after placement of protection area 12 around the drawn branch of the frame window 4 (so to speak, clockwise in Figure 1), the edge area of the protection area 12 in the window frame 4. Alternatively, you can perform this fixing by separate adhesive strips "from the roll ". The upper adhesion surface 28 serves to fix a flat protective material so that it covers the opening of window in the four protection areas 12 of four slats 2 (in fact, up, left, right, down).

Figures 2 and 3 illustrate some of multiple existing possibilities of border zone configuration left 32 in the drawings of the flat material, with which it is protection area 12 is configured. It is recognized in Figures 2 and 3 the left edge 34 of the plastering area 8 and -drawn with dashed line, since it is located behind the flat material 12- the right edge 36 of the plastering area 8 with a strong line discontinuous A perforation line or other weakening line 38 is indicated by dashed line. In the examples of the embodiment according to Figures 2 and 3 is treated, first place, of the configuration of the edge zone 32, in such a way which is fixed by an attachment with adhesion of the clamping area 10, particularly, of the foam tape 10, in the remaining strip 2, simultaneously, with ribbon 2.

Figure 2 illustrates on the one hand the possibility that the edge area 32 is essentially the same width as the foot 16 of the slat 2. However, the edge zone 32 has large circular die cut openings 40, through which Adhesion can be made between tape 10 and foot 16.

On the other hand, it is indicated with a dotted line 46 that, alternatively, the edge zone 32 can be made expressly less wide than foot 16; instead of openings 40 peripherally delimited exist now only recesses 42 with more semicircular shape.

In the embodiment according to Figure 3, the flat material 12 arrives with an edge area 32 between the tape 10 and foot 16, which occupies in width (measured in Figure 3 from the left to right) only a fraction of the width of foot 16 or tape 10. Edge area 32 is configured with recesses 42 in the form of a partial circle, where it is located between two adjacent recesses 42 respectively a tongue 44. For the illustration, a part of the tape 10 is drawn that adheres to the conformation of lath for plastering remaining and the edge area 32 of the flat material or the area of protection 12. By traction in the flat material 12 towards the right in figure 3, edge area 32 can be removed from the "intermediate space" between the tape 10 and the foot 16, without a drilling line or other line of weakening.
