Description

(a) die Leiste weist eine Basiswand auf, mit der sie an dem Fensterstock, Türstock oder dergleichen befestigbar ist;

(b) die Leiste weist mindestens einen, sich längs der Leiste erstreckenden Steg auf, der bezogen auf die Basiswand fortragend vorgesehen ist;

(c) die Leiste weist einen Basisbereich, zu dem die Basiswand gehört, und einen Vorderbereich, zu dem der mindestens eine Steg gehört, auf.

The invention relates to a plastering strip for window frames, door frames or the like at the transition to plaster, with the following features:

(a) the bar has a base wall with which it can be fastened to the window frame, door frame or the like;

(b) the strip has at least one web, which extends along the strip and is provided in a forward-moving manner with respect to the base wall;

(c) the strip has a base region to which the base wall belongs and a front region to which the at least one web belongs.

A plastering strip with the features (a) and (b) is from document DE-U-87 15 604 known.

When building buildings, the procedure is usually that Window frames and door frames (those are fixed to the structure connected, fixed window frame or door frame) in Appropriate wall openings of the shell are inserted and fastened there become. In a later phase, the shell will be outside and inside plastered. This is particularly on the outside of the building Connection of the plaster to the window frame or door frame a critical Place because of the plaster on the face of the material of the window frame or Doorstocks (usually wood, plastic or metal) butts and there no perfect bond. Because the plaster when drying something fades and there window shocks and door shocks vibrations exposed, for example by violently slamming the window or doors, there is a risk of a crack or gap between them the plaster and the window frame or door frame. Then here Moisture penetrate the window stick or in the long run Door frame damages and / or damages the plaster, for example too Crumbling of the plaster leads.

The plastering strip known from document DE-U-87 15 604 has an elastic one Adhesive tape made of foam material that doubles as a sealing tape acts on and can be attached to the window frame with the adhesive tape, Fasten the door frame or the like. The tape causes one Vibration isolation between the window frame or door frame and the bar with the plaster attached to it. Based on these Decoupling and because of the better bond between the bar and the plaster results in a more perfect, permanent error-free Plaster connection on the window frame, door frame or the like.

In the plastering strip known from document DE-U-87 15 604, the extent of Relative movements between the window frame, door frame or the like and the plaster that the created by means of the plastering strip Plaster connections can survive damage-free from the elasticity of the Foam tape determined. But there are fields of application, e.g. very large windows, windows of relatively tall houses, windows under large ones Wind load where the elasticity of the adhesive tape is insufficient, to achieve a relative movement tolerance of the desired extent.

A plastering strip with the above-mentioned features (a), (b) and (c) is off document US-A-4 512 127. With this plastering strip are the Base area and the front area with clear play in all three spatial directions movable relative to each other. Both the base area and the Front areas require their own attachment to a building component.

From document DE-A-40 17 250 is a plaster edge profile for roller shutter lintel boxes known that a base area and one relative to the base area Movable front area. The relative mobility is rectangular given to the level of the plaster layer, whereas towards the Level of the plaster layer there is no relative mobility.

Based on the plastering strip known from document DE-U-87 15 604 the invention has for its object to provide a plastering board in which principle, larger relative movement tolerances can be realized.

(d) daß der Vorderbereich eine Führungsverbindung mit dem Basisbereich hat, die eine Relativbewegung in Richtung Abstandsänderung zu der Basiswand zuläßt;

(e) und daß der Vorderbereich, getragen von dem Basisbereich, mittels des Basisbereichs an dem Fensterstock, Türstock oder dergleichen befestigbar ist.

The bar according to the invention is characterized in that

(d) that the front area has a guide connection to the base area which allows a relative movement in the direction of change in distance from the base wall;

(e) and that the front area, supported by the base area, can be fastened to the window frame, door frame or the like by means of the base area.

The bar according to the invention is no longer in one Relative movement compensation by means of an elastic adhesive tape instructed (although such an adhesive tape for attachment and additional decoupling can be provided), but it is the Relative movement tolerance in the bar itself, i.e. between their Base area and its front area, available. This is it possible without problems, a possibility of relative movement of larger size than to realize so far.

For the formation of the aforementioned relative movement Connection between the base area and the front area of the There are numerous constructive options for strips. Especially training as a connector is preferred, the Relative movement by further plugging together or limited pull apart is possible. It is preferably around an elongated plug connection in the longitudinal direction of the strip.

Preferably, the connector is fairly free of play, especially in Direction perpendicular to the plaster surface.

Another, possible alternative is the formation of the connection an integral connection of the basic area and the Front area e.g. over thin, flexible material areas like Film hinges mentioned. Functionally it comes with the compound according to the invention only that the said Realistic movement over the required distances is possible.

Preferably, the bar is delivered in the state in which the base area and the front area are connected to one another, and is in this state on the window frame, door frame or the like attached. For this reason too, it is beneficial if the connection only with considerable force or using a tool is separable. In the case of the plug connection, it is preferred that the Due to its shape, the plug connection can only be overcome a release resistor is completely separable.

A connection with a particularly preferred structure is obtained if on the base area at least one supporting from the base wall Extension and at least one receiving space on the front area picks up the extension, are present. The extension can in particular an elongated, wall-like extension, analogous to the recording room, in particular an elongated, groove-like receiving space between two relatively closely adjacent Walls. It is possible to reverse the structure, so to speak to provide at least one extension on the front area and the ' to provide at least one receiving space on the base area. The at least one receiving space in the Integrate at least one web. A well-made, stable The formation of the connection is obtained if - as preferred - two from the base wall carrying extensions are provided, the Base area in cross section is substantially U-shaped.

There are preferably two webs in the strip according to the invention provided, the front region being substantially U-shaped in cross section is. The two webs can be more or less perfect be mirrored to each other. If there are two webs are two elegantly integrated into the webs Provide recording rooms and two with support from the base wall Pair extensions.

The at least one web is preferably formed on the inside undercut from. This has advantages for binding to the plaster. Instead or in addition, however, you can undercut the web use to set a locking part that holds the End portion of a reinforcing fabric section provided on the bar is. It is generally preferred to have one on the front area of the bar Fasten the reinforcement fabric section.

The front region preferably has on that side of the at least one web, which from the Window reveal, door reveal or the like facing away, one Wall extension on, so that from the web and the wall extension in Cross-section angular plaster receiving space is formed. This Design has the particular advantage that after the application of the plaster remains less visible from the bar.

It is further preferred in an embodiment of the invention that the at least a web on the side that from the Window reveal, door reveal or the like facing away, one Has a return. This measure has the advantage that one for a lower plaster layer has a pull-off edge, but also additionally a pull-off edge for the last layer of plaster.

The bar according to the invention is preferably made entirely of plastic polyethylene and polyvinyl chloride are particularly suitable.

Fig. 4

a part of a strip of another embodiment in cross section, wherein an outside web recess can be seen.

Fig. 1 is a horizontal cross section through part of a house wall 2, which consist for example of brick or concrete can. 1 is the outside of the House, and below on the drawing side of Fig. 1 is the inside of the House. The one running from top to bottom in FIG. 1 The boundary line is the reveal 4, and that in Fig. 1 is horizontal running, upper boundary line of the wall 2 represents the outer surface 6 the unplastered wall 2. Quite a bit further to the left of 1 has an identical mirror image To prefer wall section, so that the two reveal surfaces one Limit wall opening on both sides.

In the wall opening, a window frame 8 is attached, the joint between the outside of the window frame 8 and the soffits 4 through hardened polyurethane foam 10 is filled. In the window block 8 is a glass pane 12, preferably a double glass pane, by means of a subsequently attached block bar 14 attached. So it's about around a fixed window pane 12. In the case of an openable Window sash, the pane 12 is not seated directly in the window frame 8, but in an openable window frame that hinges on the window frame 8 is attached.

On the outside of the window frame 8 is on this by means of a Adhesive tape 16 a plastering strip 18, hereinafter referred to as "strip 18" named, glued. The adhesive tape 16 is made of foam plastic high strength, which is resilient, but a relative has high compression resistance. The adhesive tape 16 also serves as a sealing tape.

Apart from the adhesive tape 16, the strip 18 consists essentially of a base area 20, a front area 22 and one Protective tab 24. The base region 20 is essentially U-shaped Cross-section formed by one in the drawn Embodiment flat base wall 26, on the back of which Adhesive tape 16 is glued, and two rectangular at the front supporting extensions 28. The extensions 28 extend like walls in the longitudinal direction of the strip 18. In principle they have a constant Wall thickness a, but are each at the free end with erratic Wall thickness increase somewhat widened.

The cross section of the front area 22 of the strip 18 can be roughly spoken - also referred to as U-shaped. It is made up of a bottom wall 30 and two of them - roughly speaking - webs 32 projecting at right angles to the front. Each web 32 is in its rear, the wall 30 closer part double-walled formed so that there is a receiving space 34 in the form of a deep groove is formed. Each receiving space 34 is closed at the front and open at the back, but the groove width at the opening a shoulder on both sides is reduced. The dimensions are such that the upper, widened end 29 of the extension 28 in question practically is accommodated without play in the associated receiving space 34, while the relevant extension 28 with its unenlarged Wall thickness essentially free of play in the opening of the receiving space reduced width sits. The base region 20 and the front region 22 have been manufactured as separate parts by plastic extrusion and are by pushing the two extensions 28 into the two Recording rooms 34 overcoming resistance at Puncturing the receiving space ends reduced width united Service.

In the drawn, combined state, the base region 20, e.g. B. when the window frame 8 moves downward under wind pressure Fig. 1 makes, relative to that which remains stationary together with the plaster Front area 22 a backward movement (i.e. downward in Fig. 1) do. The plug-in connection like a pair of telescopes between the base region 20 and the front region 22 one can such movement easily.

To the front, following the double-walled part, each web is 32 single-walled and narrower, each web bends in the front end area 32 from the inside, so that an undercut 36 is formed there. The undercuts 36 make this U-shaped Interior of the front area 22 brought plaster particularly good Stopped.

Overall, the two webs 32, as well as the entire one, have so far described front area 22, as well as the described base area 20 formed in mirror image to a common longitudinal median plane.

On the left in FIG. 1, web 32 closes on the outside strip-shaped protective tab 24. The front of the protective tab 24 is flat and has an adhesive layer 40 there Adhesive layer 40 is a protective film 42 glued on, which differs from the Ledge 18 extends to the left in FIG. 1. If you imagine that the window frame 8 is glued to all four sides Plaster is provided, then it is clear that the protective film 42 entire opening between the four plastering strips 18 covered and on this way the window frame 8 from contamination when applying the Plaster protects.

On its back, the protective tab 24 essentially has one spacer 38 projecting at right angles to the rear. The Spacer 38 is so high that the protective tab 24 on the back is supported on the window frame 8 via the spacer 38 so that the Front of the protective tab 24 substantially parallel to the front the window frame 8 is.

In Fig. 1 it can also be seen that a flush 46 on the reveal 4 is applied and a layer of top plaster 48 on the plaster 46 is applied. When driving the plaster 48 smooth you can Use the outside of the web 32 on the left in FIG. 1 as a pull-off edge.

After the entire plaster is finished, the protective film 42 removed and the protective tab 24 on a break-off material bridge 44 lower material thickness broken off.

In Figures 2, 3, 4 are for the sake of drawing Simplification only the front area 22 of a strip 18, also drawn with the omission of a protective tab 24.

Fig. 2 illustrates an embodiment in which a Reinforcing fabric section 50 by means of a closing part 52 on the bar 18 is attached. The closing part 52, which can be made of plastic, is subsequently from the front through the "opening" 54 of the bar 18 in Form a slot between the free ends of the two webs 32 has been inserted and has snapped locked there. The End region of a reinforcing fabric section 50 was between the closing part 52 and at least one of the two webs 32 clamped. The reinforcement fabric usually consists of one reticular plastic flat material. The reinforcing fabric 50 is used improved adhesion and keeping the plaster free of cracks when applied Polystyrene plates attached as full thermal insulation on the wall 2 could be.

Fig. 3 illustrates the provision of a wall extension on the in Fig. 3 left side of the left web 32. Through the wall extension 56 is an angular plaster receiving space 58 is formed. After this Applying the plaster 48 is only the small of the bar 18 free end of the wall extension 56 to see.

FIG. 4 illustrates a last formation in which the one in FIG. 4 left web 32 a recess or a Z-shaped, double Has an internal bend. In this case you can front part of the web 32 when applying the flush 46 as Use the pull-off edge and the rear part of the left web 32 when applying the top plaster 48 use as a pull-off edge. It it goes without saying that, if desired, the embodiments according to Fig. 3 and Fig. 4 with locking part 52 or other attachment of the Reinforcing fabric section can be provided.

It is emphasized that the cross section of the strip 18, that is Front area 22, the base area 20 and the protective tab 24, about whose entire length is constant, so that the bar 18 without problems can be produced by extrusion. The strip 18 preferably consists of Plastic, alternatively made of metal.
