Description

The invention relates to a connection profile for use on a building panel, as well as a finished component with a corresponding connection profile.

In drywall, in particular in the production of walls and front walls, for example, plasterboard, a cost-effective and particularly rapid implementation of construction work is generally required. In contrast, in such wall structures made of individual building panels, the problem of the butt joints between the building panels. In particular, room corners lead to a non-negligible reworking work, for example, a trowelling of corner rails. From this point of view, the cladding of shafts, columns or the like is associated with a particularly high amount of time.

To rationalize various solutions for connecting the abutting corner panels are known from the prior art, in which a subsequent filling is unnecessary. For this purpose, on the one hand, bendable plastic profiles are known, which have on both sides of a bending region U-shaped fastening sections for fastening the end faces of the adjacent building boards. Thus, in a simple and reliable way, the design can be realized on the corner adjacent building panels, without the need to fill the corner.

A disadvantage of such an embodiment, however, is that the correspondingly used profile at the corner of the end faces of the two adjacent building panels is visible across. However, deviating from the structural panels surface property of the visible profile in the corner considerably complicates the subsequent decoration of the building panels.

Another disadvantage is the not completely flat design of the structural panel provided with the profile, as this overlaps on the front and back of the adjacent building panels. Thus, a plurality of profile panels connected by profile can not be stacked to save space. To prevent damage to one another superimposed construction panels, in particular their outer layers, by the overarching profiles it requires the individual handling of the corresponding prefabricated component, which significantly increases the logistical effort.

Furthermore, a solution is known from the prior art, in which a recess is incorporated in a continuous building board, so that the arranged on the visible side cover layer is maintained. In this recess, a double-sided adhesive tape is inserted, wherein after flaps of the both sides of the recess existing building board sections by means of the double-sided adhesive tape in the corner a renewed connection of the two building board sections is created.

A disadvantage of the last embodiment, however, is the lack of stability of the recess provided with a building board, despite the use of the double-sided adhesive tape. This can lead to damage in the handling of the building board before it is installed at the place of use. In this case, on the one hand, the cover layer can tear in the region of the recess in the event of uneven lifting. Furthermore, it can come by lifting on a Bauplattenabschnitt to detach the top layer from Bauplattenkern. Not to be neglected is the risk of an impermissible breaking out of the construction board core adjacent to the recess. In particular, with plasterboard occurs almost inevitably an irregularly shaped breaking off the bottom of the recess towards tapered gypsum core. These damages either lead to the total loss of the building board or require at least a rework and thus an undesirable expenditure of time.

Object of the present invention is therefore to provide a connection profile and a finished component with a corresponding connection profile available, which overcomes the disadvantages of the previous embodiments.

The stated object is achieved by an inventive connection profile according to the teaching of claim 1. An inventive prefabricated device using a corresponding connection profile is specified in claim 8.

Advantageous embodiments are the subject of the dependent claims.

The generic connection profile is initially used for the realization of room corners in drywall. For this purpose, the connection profile is to be attached to a building board, which should have a arranged on the visible side, continuous cover layer. For arranging the connection profile on the building board, it is further required that in the building board a behind the top layer facing the rear recess is incorporated. Accordingly, the required building board is divided into a right building panel section and a left building board section in continuous cover layer.

The connection profile accordingly has a right attachment portion for attachment to the right construction panel portion and a left attachment portion for attachment to left building panel section, wherein the right mounting portion is connected to the left mounting portion via a centrally disposed bending region. To use the connection profile, an attachment of the same in the recess on the back side of the cover layer is required. Furthermore, the generic connection profile comprises a bending region on the basis of which the right fastening section can be folded relative to the left fastening section at least to the rear over an angle of 90 °. This means that, when using the connection profile on the building board, the two building board sections can be folded toward one another by 90 ° relative to each other so that, starting from a flat building board, a room corner can be realized.

To improve on the prior art, the respective mounting portions are extended by a Einsteckschenkel, by means of which a significantly improved connection with the respective Bauplattenabschnitt is achieved without the need for gripping the end faces of the structural panels sections. In this case, the Einsteckschenkel extends parallel to the plane of the respective Bauplattenabschnitts, wherein correspondingly in the respective Bauplattenabschnitt an outgoing of the recess insertion groove is required, which must extend parallel to the corresponding plane of the corresponding Bauplattenabschnitts.

The newly created embodiment of the connection profile a much better hold of the connection profile is achieved on the building board, with the improved stability of the connection profile on the building board sections also the rigidity and stability of the assembly of building board and connection profile over known designs can be increased. This in turn reduces the risk of damage to the connection profile or the cover layer in the bending area.

In addition to the connection profile according to the invention, a novel prefabricated construction element according to the invention is provided, which first of all comprises the corresponding building board in the generic manner. Here, the building board - as described above - arranged on the visible side continuous cover layer, wherein behind the cover layer a recess facing the rear is incorporated, which in turn divides the building board into a right and a left adjacent to the recess wall plate section.

The prefabricated component according to the invention is now characterized by the use of the connection profile according to the invention. Accordingly, in the building board used in the respective building panel sections insertion grooves are incorporated starting from the recess, which are aligned parallel to the plane of the structural panel section. In this insertion the Einsteckschenkel the connection profile are attached.

Particularly advantageous is the execution of the connection profile and the finished component when the connection profile is designed such that the connection profile is found completely within the recess. Ie. in the extended starting position, the connecting profile has a height which is less than the thickness of the intended building board less the thickness of the top layer. Thus, the connection profile between the cover layer and the back of the building board can be arranged, whereby a particularly advantageous and damage-free transportability of the finished component is achieved. Contrary to known designs with stiffening profile, the finished component can be layered without the risk of damage to each other.

The shape and the manufacture of the connection profile further simplifies when the right attachment portion is made substantially symmetrical to the left attachment portion. This simplifies in particular the design of the recess in the building board as well as the insertion grooves in the building board sections.

If, in the realization of the corner of the room as sharp as possible Eckgestaltung is desired, it is also of particular advantage, if a bending of the connecting profile on the bending section with the smallest possible radius. Therefore, it is particularly advantageous if the bending region is more or less a film hinge, so that a nearly sharp-edged corner is realized when the connection profile is bent by 90 ° towards the rear side. A further advantage of this embodiment is that the cover layer of the finished component passing through on the visible side is stretched only slightly by the folding of the two structural panel sections.

At the same time a simple and suitable design of the connection profile for realizing a bending of the right fastening portion relative to the left attachment portion by 90 ° to the back is achieved when the connection profile in the initial state has a V-shaped opening from the bending region to the back. Furthermore, it is advantageous if the connection profile on both sides of the bending region has a substantially triangular-shaped base portion and a subsequently plate-shaped web portion. Thus, the connection profile without viewing the Einsteckschenkel in the starting position is Y-shaped, whereby it can be inserted into a corresponding Y-shaped recess in the building board. This figure favors the one Processing the building board to create the recess. However, a particular advantage is the avoidance of damage to the building board sections in the region of the recess.

An advantageous connection of the connection profile with the building board with insertion grooves is achieved if, in addition, the connection profile can be bent at an angle of at least 170 ° on the bending profile towards the visible side. This results in that the two Einsteckschenkel of the respective mounting portions come to rest parallel to each other. In this mounting position, the connection profile can be attached to a prepared building board by inserting the Einsteckschenkel in the insertion grooves in a simple manner. In this case, it is obvious that the two building board sections are also to be folded by at least 170 ° to each other to the visible side. Thus, the connection profile can be attached to the building board in the front side engaging Einsteckschenkeln in a simple manner to the building board.

A particularly advantageous prefabricated component is created when a plasterboard is used as a building board, in which embodiment the corresponding cover layer is formed by a paper layer. In particular, in this embodiment, it is particularly advantageous if the connection profile is disposed completely within the recess. Thus, damage to the easily tearing cover layer of another resting building board is prevented. Likewise, when used as a plasterboard, the use of a connecting profile with a Y-shaped design proves to be particularly advantageous, since thus breaking out of the core layer in the region of the recess is largely avoided.

It when the connection profile is extended by a locking function is particularly advantageous. Here, the right-hand attachment section has right-hand latching means and the left-hand attachment section left-hand latching means, the embodiment of the latching means initially being insignificant provided it is ensured that the right-hand latching means engages with the left-hand latching means when the fixing sections are folded by 90 ° towards the rear ,

By means of this particularly advantageous embodiment with a latching function, it is achieved that at the place of use, starting from the planar shape of the prefabricated component, a structural plate section can be folded so that the shape of the prefabricated structural element which is angled by 90 ° results, wherein then no further retention to maintain this angled Shape is required. Now, the finished component can be easily attached to the place of use, the angle is already held automatically due to the locking.

The realization of the locking means can in this case be carried out in various ways, wherein in a first particularly advantageous embodiment of a connection profile - particularly advantageous produced extruded - the right locking means by means of a locking lug engages behind the left locking means (with right and left are selected purely arbitrarily). Thus, the connection profile together with the locking means in the extruded profile can be produced without additional rework and is thus particularly cost feasible.

Alternatively, it is possible to perform the locking means of the left side and right side similar, which engage behind each other. Conceivable here is an embodiment similar to a travel closure, so that when the fastening sections are folded by 90 ° to the rear, the locking means are hooked to one another.

With regard to the realizable locking force is also particularly advantageous if it is not too high. Rather, it is particularly advantageous if a disengagement occurs before a critical breaking load is reached. If unfavorable handling is carried out in the prefabricated component with the connection profile after engagement, it is advantageous, however, if disengagement takes place. If, for example, only one structural panel section is detected and in the other structural panel section, bending forces occur, for example, in a horizontal position under its own weight, then these bending forces can quickly lead to breakage of the structural panel section, in particular in the case of a plasterboard panel. Particularly at risk in this case is the area directly at the insertion groove. In contrast, it is advantageous if, instead, a disengagement takes place, that although the not held Bauplattenabschnitt immediately abruptly drops, however, there is the realistic possibility that in a free swinging down in the air damage due to the disengagement is prevented.
