EP0908579B1 - Border strip for the periphery of an interior construction panel - Google Patents

Abstract

The edging strip comprises a U-shaped main section which fits over the edge of plasterboard (28) and with two lower flanges to form a H-profile. The lower flanges are joined to the strip by thin wall sections to enable either to be broken off after fitting to the plasterboard. A self adhesive foam strip secured the outer edge of the profile to the adjoining wall e.g. to a window/door frame. A protective foil on the outside of the foam strip is removed before fitting.

Description

The invention relates to a border for the edge of a Indoor building board, especially a plasterboard.

In the interior of buildings, light building boards are often used for many things Tasks used, being as particularly typical applications - cladding of walls to create a smooth wall surface, the cladding of partitions e.g. in metal stand design and called the cladding of thermal insulation layers in sloping ceilings should be. The most common form of building board for such Applications is the plasterboard, in which a core consists of one Plaster material covered on both flat sides by a layer of cardboard is.

The connection of the edges of building boards to other components, e.g. Window frame, door frame, building board adjoining the corner, Rafters and many other things often cause problems. Frequently e.g. the building board is not cut perfectly to size, so that an undesirably large gap remains, or the edge of the Building board not exactly parallel to the subsequent component. If at such junctions with filling with filler laborious manual labor is required. The same applies to the moreover, very expensive alternative of spraying with a permanently elastic grout. Such fillings in the joint between the edge of a building board and the subsequent component are also in many cases not very visually appealing and subject to Risk of cracking after some time.

The invention has for its object a border for the Edge area of the building board expose that a little labor-intensive, optically clean and permanently crack-free connection between the building board and a subsequent component allows.

(a) sie besteht aus Kunststoff;

(b) sie weist im Querschnitt eine Basis und zwei, an der ersten Seite der Basis von dieser fortragende Einfaßschenkel auf, wobei der so gebildete, im wesentlichen U-förmige Kanal zur Aufnahme eines Randbereichs der Bauplatte vorgesehen ist.

(c) sie weist im Querschnitt mindestens einen weiteren Schenkel auf, der auf der gegenüberliegenden, zweiten Seite der Basis von dieser fortragt;

(d) der weitere Schenkel weist an seiner Wurzel eine derartige Materialschwächung auf, daß er von der Einfaßleiste abtrennbar ist;

(e) und auf der zweiten Seite der Basis ist ein Klebeband angeklebt, das auf seiner der Basis abgewandten Seite eine Klebefläche besitzt.

To achieve this object, the border strip is characterized according to the invention by the following features:

(a) it is made of plastic;

(b) it has a base in cross-section and two, on the first side of the base of this supporting leg, wherein the thus formed, substantially U-shaped channel is provided for receiving an edge region of the building board.

(c) it has at least one further leg in cross section, which protrudes from the base on the opposite, second side thereof;

(d) the further leg has at its root such a material weakening that it can be separated from the border strip;

(e) and on the second side of the base there is an adhesive tape which has an adhesive surface on its side facing away from the base.

The border strip according to the invention can, usually after Bending over or severing another leg or several other legs by means of the adhesive tape to the glue the following component. Afterwards (or optionally before) can the building board with its edge area in the substantially U-shaped Insert the channel of the border strip. If the edge face, e.g. due to undersized building board or non-parallelism between the other component and the end face of the building board, not consistently to the bottom of the U-shaped channel or to the first side of the Base of the bezel is enough, this is not disturbing at all, because the Edging strip optically closes the joint there. Rework for Closing the joint is not necessary. There remains a certain Possibility of movement of the building board in the direction perpendicular to the Base of the border strip exist so that permanent freedom from cracks Transition between the building board and the subsequent component is achieved.

Depending on the application, you can use the other leg or the other Completely cut off the legs of the trim strip during assembly. Alternatively, you can also add another leg or even two initially pivot additional legs only in particular by 90 ° and initially still on the border, especially around one Protection against contamination and / or damage for the subsequent Component. Then later the other leg is usually or the other legs completely separated; in special situations you can also him or her forever in the connection area leave.

The further leg is preferably aligned with one of the Einfaßschenkel. Two detachable, additional legs are preferably provided, preferably each of the further legs with a the border leg is aligned. With this training results preferably an H-shaped cross section of the border strip.

It is also preferred to weaken the material at the root Leg provided such a reduced wall thickness that the further legs can be broken off by pivoting movement. alternative Possibilities are e.g. a perforation.

In a further development of the invention, you can also on the first page stick an adhesive tape on the base, the one on its side facing away from the base Side has an adhesive surface. In certain applications it is favorable to be able to glue the edging strip to the building board, e.g. around not to have to hold them separately during assembly.

Conveniently, the tape is a foam plastic tape what brings increased elasticity and tolerance compensation ability.

The adhesive tape preferably has on its side facing away from the base A peelable film. In this way it becomes Adhesive surface only after removing the peel-off film for its function exposed.

It is pointed out that the border strip according to the invention usually not (or only very subordinate) the function of the Holding the building board; rather you fix the building board usually with other fasteners, e.g. Screws. Further it is pointed out that plasterboard is a very typical Examples of building boards with which the invention Socket strip is used together. Other types of building boards are also possible, especially plastic building boards, Pressed fibreboards, building boards made of wood or wood-based materials, building boards made of wood or wood-based materials with plastic coating and others more. The invention also relates to the combined arrangement of a building board and at least one border strip according to the invention.

1 in another exemplary installation state, but in a horizontal cross section but on a smaller scale.

1 shown in the following for the sake of brevity only referred to as "bar", has an H-shaped cross section and exists made of plastic, in particular PVC (polyvinyl chloride) or PP (Polypropylene). As it were, the slash of the H represents a base 4 (in Form a flat wall) of the strip 2. Project from the base 4 at right angles upwards in Fig. 1 two Einfaßschenkel 6. By the Base 4 and the mounting leg 6 is a substantially U-shaped Channel 8 limited. The upper side of the base 4 in FIG. 1 is at another Make the registration referred to as the "first page".

Two protrude on the opposite, second side of the base 4 further legs 10 down in Fig. 1, each of the further Leg 10 is aligned with one of the Einfaßschenkel 6. Each of the two another leg 10 has at its root, ie the transition to Outside corner area between the base 4 and the mounting leg there 6, a material weakening 12 in the form of a bilateral Constriction in wall thickness. The material weakening is 12 preferably made such that the relevant leg in question 10 can be pivoted or bent by 90 ° once, but with multiple turns or when turning significantly more than 90 ° breaks off from the remaining bar 2.

On the lower, second side of the base 4 of the strip 2 in FIG. 1 is a double-sided adhesive foam plastic adhesive tape 14 adhered. The is on the side facing away from the base 4 adhesive surface 16 covered by a release film 18 in the delivery state of the bar 2. For the use of the strip 2, the release sheet 18 is peeled off, so that the adhesive surface 16 is exposed for use.

In addition, the possibility is shown in dashed lines in Fig. 1 shown, also on the first side of the base 4 of the bar 2 to stick double-sided adhesive foam plastic adhesive tape 20.

In Fig. 2, the masonry 22 of a window reveal is shown, wherein the arrow a marks the direction to the outside of a building, while the opposite arrow i indicates the direction towards the inside of the Marked building. A window frame 24 is in the window reveal 22 used. At right angles to the plane of the window frame 24 and parallel to the surface 26 of the reveal 22 runs from the inside of the building Window frame 24 is a gypsum board 28. The gypsum board 28 is z. B. by means of locally applied adhesive mortar 30 on the surface 26 of the reveal 22 attached, e.g. to re-plaster the Reveal surface 26 to be superfluous or to adapt to a size to create newly used window frames 24.

The lower edge area 32 in FIG. 2 (essentially in the building runs vertically) of the building board 28 is in the U-shaped channel 8 Bar 2 added, being between the end face of the edge area 32 and the base 4 of the bar 2 has a little "air". One sees, that for mounting the bar 2 on the window frame 24 of FIG. 1 left, further leg 10 has been bent 90 ° to the left. The right leg in FIG. 1 and in FIG. 2 is not been turned. The bar 2 is either before inserting the Building board 28 or after union with the building board 28 through Glued by means of the adhesive tape 14 attached to the window frame 24 Service. The right, further leg 10 has as a contact surface for served the edge of the window frame 24. Alternatively, you can right, further leg 10 by multiple back and forth Swing away from bar 2 and then stop bar 2 glue the window frame 24, e.g. if you have the stop function of the right, further leg 10 is not required.

Starting from the state shown in Fig. 2, one can with the Continue finishing work in the building, e.g. the inside of the building board 28 filler or paper or paint; the left turn further legs 10 can finally by swiveling in Direction of arrow i can be canceled, whereupon one optically has good connection of the building board 28 to the window frame 24 in front of it.

3 shows a first metal stud wall 36 and one second metal stud wall 38 adjoining it at right angles. Each of the two metal stud walls 36, 38 is on both sides with building boards 28 in Form clad in plasterboard. At the point where a building board 28 of the second wall 38 at right angles to a building board 28 of the first Connects to wall 36, a bar 2 is provided. The one in the U-shaped Channel 8 has recorded edge area 32 of the building board 28 again some distance between its end face and the base 4. One of the other legs 10 of the bar 2 is for assembly has been broken off, the other, further leg 10 is quite analog as in the example of use of FIG. 2, by 90 ° to the outside been turned. This other leg 10 can be, as in 2, later cancel entirely, optional but also leave it on the wall construction forever.

Attention is drawn to the fact that there are uses at which you cancel both other legs 10 for assembly, but there are also uses where you can assemble both turns another leg outwards. In most cases, if a protective function by a further leg 10 is desired, need only a single, additional leg 10. Still it is usually more practical, the bar 2 with two other legs 10 to deliver, because then you no longer have to pay attention to the construction, "How around" the bar 2 must be installed.

The width of the channel 8 is conveniently dimensioned so that the Bar 2 sits slightly jamming on the edge area 32 of the building board 28. The manufacturer best supplies strips 2 with several widths of the Channel 8 if strips 2 are available for several building board thicknesses should.
