Description

The invention relates to a door leaf which is used in particular in a front door. The invention also relates to a method for installing a door leaf and a house door that has such a door leaf.

Doors are known to consist of one or more door leaves or door leaves, a frame as a wall bracket for the door leaf, fittings, hinges and handles and handles as locking and opening mechanisms. Other components are, for example, reveal linings, seals and dampers, inscriptions with names, digits and numbers, bells, skylights and spies, letterboxes or mailboxes as well as sensors, alarm and video surveillance. The size of a door results from the tasks and is often regulated by law with minimum dimensions, such as for escape and panic doors.

Front doors are available in different designs and made of different materials, such as wood or aluminum. Aluminum front doors look modern and are also functional. They are relatively lightweight, easy to care for and extremely robust. Aluminum is weather-resistant and therefore a door made of aluminum is particularly durable. The insulation on the inside of the front door ensures good heat and, if necessary, sound insulation. A wide range of colors makes aluminum doors particularly popular.

Aluminum front doors have a door leaf frame that is provided with an infill. If the filling is fitted into the door leaf frame, it is a so-called insert filling. Doors with insert panels usually have a visible door leaf and recognizable sealing edges.

If, on the other hand, the filling is placed on the door leaf frame, it is a so-called attachment filling that partially or completely covers the door leaf frame and creates additional space for stronger insulation and thus offers a relatively high thermal insulation value.

With an attachment panel, a distinction must be made between a one-sided leaf-enclosing design, in which the door leaf frame is either covered on the outside or sometimes on the inside, and a two-sided leaf-enclosing design in which the door leaf frame is covered on both the outside and the inside. The double-sided or double-sided leaf-enclosing panel is often used for design-oriented front doors and for special technical requirements. However, it is technically the most complex to produce.

A door leaf with an attachment panel is off DE 20 2013 102 436 U1 famous.

In practice, the attachment panel and the door leaf frame are often manufactured by different suppliers. The company that manufactures the door leaf usually obtains the attachment panel and the door leaf frame in individual parts from the suppliers and then assembles them manually to form the door leaf. The production of the door leaf is therefore associated with complex logistics and assembly.

The invention is based on the object of creating a door leaf which is provided with an attachment panel and which can be produced comparatively easily.

This object is achieved by a door leaf according to claim 1, a method for installing a door leaf according to claim 15 and a house door according to claim 20. Preferred embodiments of the invention are the subject of claims 2 to 14 and 16 to 19.

The door leaf according to the invention is particularly suitable for a house door and comprises a door leaf frame, which has an inner surface, and an attachment panel covering the leaf at least on one side, which is fastened to the door leaf frame. The attachment panel includes a first cover panel forming the outside of the door leaf, a second cover panel forming the inside of the door leaf, and insulation disposed between the first cover panel and the second cover panel and having an end face facing the inner surface of the door leaf frame .

According to the invention, the door leaf frame has at least one projection on the inner surface, which is designed to form a positive and/or non-positive connection with the attachment panel when the door leaf is in the assembled state.

The invention is based on the finding that by providing a positive and/or non-positive connection between the door leaf frame and the attachment panel, a reliable attachment of the attachment panel to the door leaf frame can be achieved with relatively simple manufacture. The main reason for this is that by providing the positive and/or frictional connection, the attachment panel can be supplied in a pre-assembled state, in contrast to conventional production, and the door leaf frame can be easily aligned with the attachment panel and reliably connected to it. The pre-assembled Attachment panel simplifies the logistics and reduces the effort and production time for the manufacture of the door leaf.

In a preferred embodiment, the door leaf has an attachment panel that covers the leaf on both sides and thus has relatively high thermal insulation values and a visually appealing design. The attachment panel is preferably designed as a pre-assembled component, in which the first cover panel, the second cover panel and the insulation are connected to one another before being attached to the door leaf frame, so that easy handling and logistics are ensured.

In a further preferred embodiment of the door leaf, the insulation on the end face has at least one recess into which the projection of the door leaf frame engages. The recess ensures an effective form and force fit.

Advantageously, the projection is made of a deformable, preferably elastically deformable, material. On the one hand, the deformability of the projection contributes to a reliable positive and non-positive fit due to the restoring force caused by a deformation of the projection. On the other hand, the deformability of the projection causes a certain resilience of the door leaf frame in relation to the attachment panel, which allows easy positioning and alignment of the door leaf frame.

The door panel frame includes an outer surface facing away from the inner surface, a first connection surface facing the outside of the door panel, and a second connection surface facing the inside of the door panel. Expediently, the first cover panel forms a first overhang projecting beyond the insulation and/or the second cover panel forms a second overhang protruding beyond the insulation. Depending on whether there is one overhang or two overhangs, there is an attachment panel that covers the sash on one side or on both sides. The first cover panel is connected to the first connecting surface of the door leaf frame in the area of the first overhang. Alternatively or additionally, the second cover panel can be connected to the second connecting surface of the door leaf frame in the area of the second overhang.

In a further preferred embodiment of the door leaf, the first cover panel and the door leaf frame and/or the second cover panel and the door leaf frame are connected to one another by an adhesive tape, in particular on both sides. The adhesive tape, which is expediently designed as an acrylate adhesive tape, ensures a reliable connection between the door leaf frame and the attachment panel and, before the door leaf is installed, is covered with a cover that can be removed from the pressure-sensitive adhesive, which cover consists in particular of paper or a film and is removed during the installation of the door leaf.

The door leaf frame preferably comprises at least one leaf profile which has a predetermined length and has the first connecting surface and the second connecting surface. The wing profile is preferably made of metal, in particular aluminum. The wing profile is expediently composed of at least two profiles which are preferably connected to one another by at least one connecting web, in particular an insulating web made of plastic.

In a preferred embodiment, the door leaf comprises at least one fixing seal attached to the leaf profile, which has a predetermined length and forms the projection. The fixing seal, for example in the form of a conventional central seal, is preferably arranged in a displaceable manner on the connecting web in order to be able to be placed in a predetermined position on the wing profile. For this purpose, the connecting web can have a guide groove, designed in particular as a T-groove, into which the fixing seal is inserted. Depending on the desired pressing force to be exerted on the insulation by the fixing seal, the ratio of the length of the fixing seal to the length of the wing profile is preferably between 1:20 and 1:1, preferably between 1:10 and 9:10. The fixing seal is preferably made of plastic or an elastomer, in particular nitrile butadiene rubber (NBR) or ethylene propylene diene rubber (EPDM), or a fluorine rubber, in particular perfluorine rubber (FFPM).

With regard to a practical design, the door leaf preferably comprises at least two, preferably at least four, leaf profiles that are assembled to form the door leaf frame. If the door leaf frame is composed of two leaf profiles, these expediently have an L-shape. If the door leaf frame is composed of four leaf profiles, each leaf profile expediently forms one side of the door leaf frame.

The door leaf frame preferably has corner areas in which the leaf profiles are connected to one another by means of corner connectors. The corner connectors and the wing profiles can be connected to one another by gluing and/or pressing. Alternatively or additionally, the corner connectors and the wing profiles can be connected to one another by means of tapered pins and/or by means of screws or another means of connection in order to achieve a firm connection in the shortest possible time.

The first cover panel and/or the second cover panel are expediently made of a material selected from the group consisting of metal and metal alloys, preferably aluminum and aluminum alloys, plastic, wood, glass and composite materials made from the aforementioned materials . The insulation is conveniently made of a material selected from the group consisting of rigid polymeric foams, preferably rigid polyurethane polymeric foams. The insulation can be reinforced by an insert made in particular of wood and/or metal and/or plastic.

With regard to high heat and/or sound insulation, the attachment panel advantageously has a thickness of approximately 4 cm to approximately 20 cm, in particular approximately 5 cm to approximately 10 cm.

1. a) Bereitstellen der Aufsatzfüllung;
2. b) Bereitstellen der Flügelprofile;
3. c) Verbinden der Flügelprofile zur Bildung des Türflügelrahmens bei gleichzeitigem Verbinden mit der Aufsatzfüllung, und zwar derart, dass der Vorsprung im montierten Zustand des Türflügels eine form- und/oder kraftschlüssige Verbindung mit der Aufsatzfüllung bildet.

The method according to the invention for assembling the door leaf described above has the following method steps:

1. a) providing the essay filling;
2. b) providing the wing profiles;
3. c) Connecting the leaf profiles to form the door leaf frame while simultaneously connecting to the attachment panel, in such a way that the projection forms a positive and/or non-positive connection with the attachment panel when the door leaf is assembled.

In a preferred embodiment of the method, in method step a), the attachment filling is provided as a preassembled component in which the first cover panel, the second cover panel and the insulation are connected to one another.

• Befestigen von wenigstens einer Fixierungsdichtung, vorzugsweise von wenigstens zwei Fixierungsdichtungen, an wenigstens einem der Flügelprofile, vorzugsweise an allen Flügelprofilen. Die Fixierungsdichtung wird hierbei vorzugsweise in den Verbindungssteg des Flügelprofils eingesetzt und zweckmäßigerweise durch Verschieben in der Führungsnut des Verbindungsstegs an einer vorbestimmten Position platziert.

In a further preferred embodiment of the method, method step b) includes one or more of the following measures:

• Attaching at least one fixing seal, preferably at least two fixing seals, to at least one of the wing profiles, preferably to all wing profiles. In this case, the fixing seal is preferably inserted into the connecting web of the wing profile and expediently placed in a predetermined position by sliding it in the guide groove of the connecting web.

Attaching the adhesive tape to the first connecting surface and/or to the second connecting surface of at least one of the wing profiles, preferably of all wing profiles. The adhesive tape is preferably applied in such a way that the cover protrudes beyond the airfoil. In this way, the cover can be easily grasped and pulled off at a later stage of assembly. The adhesive tape is expediently cut off at the end of the wing profile in such a way that the cover is removed from the pressure-sensitive adhesive in the area in which the cover protrudes beyond the wing profile. It has proven to be particularly advantageous with regard to easy gripping and pulling off of the cover if the cover is folded over over the first connecting surface or over the second connecting surface of the wing profile.

Provision of at least one fastening hole for at least one corner connector, in particular by drilling or punching, on at least one of the wing profiles, preferably on all wing profiles. The fastening hole or the fastening holes serve to accommodate a fastening means, such as in particular tapered pins or screws.

Arranging at least one corner connector on at least one of the wing profiles, preferably on all wing profiles. The corner connector and the wing profile are advantageously connected to one another by gluing and/or pressing for the purpose of pre-fixing.

• Einfügen der Flügelprofile zwischen das erste Deckpaneel und das zweite Deckpaneel, und zwar derart, dass der Vorsprung, der vorteilhafterweise an der Fixierungsdichtung ausgebildet ist, gegen die Isolierung gedrückt und das Flügelprofil in Bezug auf die Aufsatzfüllung positioniert wird. Der Vorsprung wird hierbei vorzugsweise zum Eingriff in die Aussparung der Isolierung gebracht.
• Befestigen der Eckverbinder an den Flügelprofilen zur Bildung des Türflügelrahmens. Der Eckverbinder und das Flügelprofil werden hierbei vorzugsweise mittels Kegelstifte und/oder mittels Schrauben miteinander verbunden. Die Kegelstifte oder Schrauben werden zweckmäßigerweise durch die Befestigungslöcher hindurch in den Eckverbinder getrieben. Vor allem die Verbindung mit Kegelstifte hat sich in diesem Zusammenhang als besonders vorteilhaft erwiesen. So lässt es die Benutzung von Kegelstiften zu, dass das Befestigungsloch und eine entsprechende Aussparung in den Eckverbinder vor dem Einsetzen der Kegelstifte nicht fluchtend, sondern leicht außermittig zueinander angeordnet werden. Dies hat zur Folge, dass aufgrund der konischen Verjüngung der Kegelstifte das Befestigungsloch und die Aussparung beim Einsetzen der Kegelstifte in die Eckverbinder zueinander zentriert und dadurch die Eckverbinder und die Flügelprofile gegeneinander verspannt werden. Eine zuverlässige und präzise Verbindung der Flügelprofile ist damit sichergestellt.

In a further preferred embodiment of the method, method step c) comprises one or more of the following measures:

• Insertion of the wing profiles between the first cover panel and the second cover panel, in such a way that the protrusion advantageously formed on the fixing gasket is pressed against the insulation and the wing profile is positioned with respect to the attachment panel. In this case, the projection is preferably brought into engagement with the recess in the insulation.
• Fastening the corner connectors to the sash profiles to form the door sash frame. In this case, the corner connector and the wing profile are preferably connected to one another by means of tapered pins and/or by means of screws. The tapered pins or screws are conveniently driven through the mounting holes into the corner connector. Above all, the connection with taper pins has proven to be particularly advantageous in this context. Thus, the use of taper pins allows the mounting hole and a corresponding recess in the corner connector to be left open prior to inserting the taper pins aligned, but slightly off-centre to each other. As a result, due to the conical taper of the tapered pins, the fastening hole and the recess are centered in relation to one another when the tapered pins are inserted into the corner connectors, and the corner connectors and the sash profiles are thereby braced against one another. A reliable and precise connection of the sash profiles is thus ensured.

Aligning the door leaf frame with respect to the attachment panel in such a way that the leaf profiles are aligned with the edge of the first cover panel and/or the second cover panel or at least come to lie within the contour of the cover panels. In this way, the leaf profiles are covered by the cover panels in the installed state of the door leaf and are not visible to an observer from the outside or the inside of the door leaf, which is thus provided with an attachment panel covering the leaf.

Pulling the cover off the adhesive tape in such a way that the first cover panel is connected to the first connecting surface of the door leaf frame by the adhesive tape in the area of the first overhang and/or the second cover panel is connected to the second connecting surface of the door leaf frame by the adhesive tape in the area of the second overhang is connected. The adhesive tape ensures a reliable connection between the door leaf frame and the attachment panel.

Pressing the first cover panel and/or the second cover panel against the door leaf frame to activate the adhesive tape effect. In this context, it has proven to be advantageous to press the cover panels and the door leaf frame together by means of a rolling tool that can be moved along the edge of the cover panels in order to achieve a circumferential and even contact pressure. The rolling tool expediently generates the contact pressure with pneumatic support.

In a preferred embodiment of the method according to the invention, other conventional components of the door leaf, in particular sealing elements and/or fittings and/or strips, are fastened to the door leaf frame and/or the attachment panel at a short time interval from method step c). This timely attachment of common components of a door leaf contributes to a relatively short production time and is only made possible by the method according to the invention. Because the conventional installation of a door leaf with a leaf-covering attachment panel requires relatively long waiting times after the connection of the door leaf frame and attachment panel before the door leaf can be processed further.

The door according to the invention, which is in particular a house door, is characterized by the door leaf according to the invention.

In the 1 The door shown serves as a front door 1 and has a door leaf 10 which is fastened to a frame 2 by means of hinges (not shown) and which defines an outer side 11 and an inner side 12 in relation to the front door 1 . The door leaf 10 has an in 1 door leaf frame 20 which cannot be seen and which has an outer surface 22 facing the frame 2 and an inner surface 21 facing away from the frame 2 . The door leaf 10 also has an attachment panel 40 attached to the door leaf frame 20, which in the present case covers the leaf on both sides. Depending on the application, the door leaf 10 can also have an attachment panel 40 covering the leaf on one side.

In the 1b illustrated front door 1 differs from the front door 1 according to 1a characterized in that on the door leaf 10 no attachment panel 40, but an insert panel 60 is attached. The insert panel 60 does not cover the leaf, so that the door leaf frame 20 can be seen by an observer.

Like those in particular 2a and 2 B reveal, the attachment panel 40 comprises a first cover panel 41, which forms the outer side 11 of the door leaf 10, a second cover panel 42, which forms the inner side 12 of the door leaf 10, and insulation 43, which is located between the first cover panel 41 and the second Cover panel 42 is arranged and has one of the inner surface 21 of the door leaf frame 20 facing the end face 44. The attachment filling 40 has a thickness d _A which is between approximately 4 cm and approximately 20 cm, in particular between approximately 5 cm and approximately 10 cm, preferably approximately 7 cm. The insulation 43 has a thickness D _I , which advantageously makes up between 80% and 95% of the thickness d _A of the attachment panel 40 and thus ensures good thermal insulation in particular. The insulation 43 is made of a material selected from the group consisting of rigid polymer foams, preferably rigid polyurethane polymer foams. With regard to effective protection against burglary, the insulation 43 can be reinforced with an insert made in particular of wood and/or metal and/or plastic.

The first cover panel 41 and/or the second cover panel 42 are made of a material selected from the group consisting of metal and metal alloys, preferably aluminum and aluminum alloys, plastic, wood, glass and composite materials made from the aforementioned materials , included to accommodate different design needs.

The door frame 20 has, in particular, how 2 B can be seen, on the inner surface 21 at least one projection 31, which is designed to form a positive and / or non-positive connection with the top panel 40 in the assembled state of the door leaf 10. The projection 31 made of a deformable, in particular elastically deformable, material is part of a fixing seal 30 which has a predetermined length L _F and engages in a recess 45 on the end face 44 of the insulation 43 to ensure a reliable force and form fit guarantee. With regard to the deformability of the projection 31, the fixing seal 30 can expediently be made of plastic or an elastomer, in particular nitrile butadiene rubber (NBR) or ethylene propylene diene rubber (EPDM), or a fluorine rubber, in particular perfluorine rubber (FFPM ), consist.

How in particular 2 B can also be seen, the door leaf frame 20 includes a first connecting surface 23, which faces the outside 11 of the door leaf 10, and a second connecting surface 24, which faces the inside 12 of the door leaf 10. The first cover panel 41 forms a first overhang 46 which projects beyond the insulation 43 , whereas the second cover panel 42 forms a second overhang 47 which projects over the insulation 43 . The first cover panel 41 is connected in the area of the first projection 46 to the first connecting surface 23 of the door leaf frame 20 by means of an adhesive tape 50 on both sides. The second cover panel 42 is connected in the area of the second projection 47 to the second connecting surface 24 of the door leaf frame 20 by means of an adhesive tape 50 on both sides. Depending on the application, other fastening means can also be used instead of the adhesive tape 50 on both sides. In addition, sealing elements 33 which seal the door leaf 10 can be fastened to the first projection 46 and/or to the second projection 47 . The expediently as an acrylate adhesive tape, that is based on acrylate, and thus strongly adhesive designed adhesive tape 50 has a removable cover 51 for the pressure-sensitive adhesive 52, which consists in particular of paper or a film and which is removed during the assembly of the door leaf 10.

In the present case, the door leaf frame 20 consists of four leaf profiles 25a, 25b, 25c, 25d, as shown in FIG 2a reveals. The wing profiles 25a, 25b, 25c, 25d made of metal, in particular aluminum, each have a predetermined length L _P and form the first connecting surface 23 and the second connecting surface 24. The wing profiles 25a, 25b, 25c, 25d are each composed of at least two profiles 26, 27 together, which are connected to one another by at least one connecting web 28, which is in particular an insulating web made of plastic.

The connecting web 28 has a guide groove 32 designed in particular as a T-groove, in which the fixing seal 30 is arranged in a displaceable manner.

Each of the wing profiles 25a, 25b, 25c, 25d can have one or more fixing seals 30 and thus projections 31. With regard to an appropriate pressing force, which is exerted by the projection 31 of the fixing seal 30 on the insulation 43 and thus the top panel 40, the ratio of the length L _F of the fixing seal 30 to the length L _F of the wing profile 25a, 25b, 25c is advantageously , 25d, on which the fixing seal 30 is arranged, between 1:20 and 1:1, preferably between 1:10 and 9:10, further preferably between 2:10 and 6:10, such as in particular 2c reveals.

In the corner areas of the door leaf 10, the leaf profiles 25a, 25b, 25c, 25d are connected to one another by means of corner connectors 29. The corner connectors 29 and the wing profiles 25a, 25b, 25c, 25d can be connected to one another by gluing and/or pressing. Alternatively or additionally, the corner connectors 29 and the wing profiles 25a, 25b, 25c, 25d can be connected to one another by means of screws or, as in the present exemplary embodiment, by means of tapered pins 35, which are arranged in fastening holes 34 of the wing profiles 25a, 25b, 25c, 25d.

The assembly of the door leaf 10 described above differs from the conventional assembly of a door leaf provided with an attachment panel covering the leaves on both sides, above all in that the attachment panel 40 is a pre-assembled component in which the first cover panel 41, the second cover panel 42 and the insulation 43 are connected to one another are provided. The leaf profiles 25a, 25b, 25c, 25d, which are provided individually, are connected to each other to form the door leaf frame 20 and at the same time to the attachment panel 40, in such a way that the projection 31 in the assembled state of the door leaf 10 has a shape and/or frictional connection with the top panel 40 forms.

As the 3 , 4 and 4a until 4k indicate that the method for assembling the door leaf 10 comprises the following method steps.

In the first step, how 4a shows the wing profiles 25a, 25b, 25c, 25d mitred and cut to the desired length L _P . The fixation gaskets 30 are cut to the desired length L _F . The corner connectors 29 are cut to length from a corresponding profile. Like those in particular 2a and 2c give to recognize, varies the number and the length L _F of the fixing seals 30 in the individual wing profiles 25a, 25b, 25c, 25d. in the in 2a Two fixing seals 30 are arranged in the respective corner regions of the door leaf frame 20 in the upper, horizontal leaf profile 25a and in the lateral, vertical leaf profiles 25b and 25d. The length L _F of the fixing seals 30 arranged in the vertical wing profiles 25b and 25d is approximately 5% to 15% of the length L _P of the wing profiles 25b and 25d. The ratio of length L _F to length L _P is therefore between approximately 1:20 and approximately 3:20. in the in 2a lower, horizontal wing profile 25c, however, the fixing seal 30 extends almost over the entire length L _P of the wing profile 25c in order to ensure reliable support of the attachment panel 40. The ratio of the length L _F to the length L _P is therefore between approximately 9:10 and approximately 10:10 in this area.

In the second step, how 4b shows, the wing profiles 25a, 25b, 25c, 25d provided with the fastening holes 34 for the taper pins 35, for example with the aid of a hand punch.

In the third step, how 4c shows the fixing seals 30 attached to the wing profiles 25a, 25b, 25c, 25d. For this purpose, the fixing seals 30 are inserted into the connecting web 28 of the wing profiles 25a, 25b, 25c, 25d and placed at a predetermined position.

In the fourth step, how 4d shows the adhesive tapes 50 attached to the wing profiles 25a, 25b, 25c, 25d. The adhesive tapes 50 are attached to the first connecting surface 23 and to the second connecting surface 24 of the wing profiles 25a, 25b, 25c, 25d in such a way that the cover 51 projects beyond the wing profiles 25a, 25b, 25c, 25d. The adhesive tape 50 is in this case attached to the respective ends of the wing profiles 25a, 25b, 25c, 25d cut off, in such a way that in the area in which the cover 51 protrudes beyond the wing profiles 25a, 25b, 25c, 25d, although the cover 51 is removed from the pressure-sensitive adhesive 52, the cover 51 remains intact. In order to enable the cover 51 to be easily grasped and later pulled off, the cover 51 is folded over the connecting surfaces 23, 24 of the wing profiles 25a, 25b, 25c, 25d.

In the fifth step, how 4e shows the wing profiles 25a, 25b, 25c, 25d and the corner connectors 29 aligned with one another and pushed together. The wing profiles 25a, 25b, 25c, 25d are inserted between the first cover panel 41 and the second cover panel 42 of the attachment panel 40 in such a way that the projection 31 formed on the fixing seal 30 engages in the recess 45 and is pressed against the insulation 43, whereby the Wing profiles 25a, 25b, 25c, 25d are positioned in relation to the attachment panel 40. The wing profiles 25a, 25b, 25c, 25d and the corner connectors 29 can be glued or alternatively or additionally pressed depending on the application in order to achieve a pre-fixation.

In the sixth step, how 4f shows the interconnected wing profiles 25a, 25b, 25c, 25d aligned to the attachment panel 40. The door leaf 10 is then subjected to a visual inspection.

In the seventh step, how 4g shows, the wing profiles 25a, 25b, 25c, 25d and the corner connectors 29 are firmly connected to one another by means of the tapered pins 35 arranged in the fastening holes 34. The mounting holes 34 and corresponding recesses in the corner connectors 29 are not aligned prior to the insertion of the taper pins 35 but are slightly off center with respect to each other. Due to the conical taper of the tapered pins 35, the fastening holes 34 and the associated recesses in the corner connectors 29 are centered in relation to one another when the tapered pins 35 are introduced into the corner connectors 29. The corner connectors 29 and the wing profiles 25a, 25b, 25c, 25d are braced against one another in this way.

In the eighth step, how 4 hours shows, the door leaf frame 20 formed by the interconnected leaf profiles 25a, 25b, 25c, 25d is aligned in relation to the top panel 40 in such a way that the leaf profiles 25a, 25b, 25c, 25d are aligned with the edge of the first cover panel 41 and the second cover panel 42 match or at least come to lie within the contour of the cover panels 41, 42. This alignment is facilitated by the deformability of the projection 31. The door leaf 10 is then subjected to another visual inspection.

In the ninth step, how 4i shows, the respective covers 51 are pulled off the adhesive tapes 50 in such a way that the first cover panel 41 in the area of the first overhang 46 is connected by the adhesive tape 50 to the first connecting surface 23 of the door leaf frame 20 and the second cover panel 42 in the area of the second overhang 47 be connected to the second connecting surface 24 of the door leaf frame 20 by the adhesive tape 50 . The covers 51 are each pulled out of the gap existing between the connecting surfaces 23, 24 and the insulation 43.

In the tenth step, how 4y shows, the first cover panel 41 and the second cover panel 42 are pressed against the adhesive tapes 50 and thus against the door leaf frame 20 . For this purpose, the cover panels 41, 42 and the door leaf frame 20 can advantageously be pressed together by means of a rolling tool that can be moved along the edge of the cover panels 41, 42.

In the eleventh step, how 4k shows, the door leaf 10 is subjected to a final visual inspection before further components of the door leaf 10, such as fittings or hinges, are fastened to the door leaf frame 20 and/or to the attachment panel 40 immediately thereafter.

The door leaf 10 described above is characterized by a comparatively simple and quick assembly. This is mainly due to the fact that the provision of a positive and/or non-positive fit between the door leaf frame 20 and the attachment panel 40 as a result of the deformable projection 31 enables a precise alignment of the leaf profiles 25a, 25b, 25c, 25d forming the door leaf frame 20 in relation on the pre-assembled top panel 40 can be achieved. The pre-assembled attachment panel 40 also simplifies the logistics and handling and reduces the effort and the production time for the production of the door leaf 10.
