Description

Die Erfindung bezieht sich auf eine Tür, bestehend aus zwei an zumindest einer Falzfläche der Tür über ein U-förmiges Verbindungsprofil miteinander verbundenen Deckblättern, wobei das Innere des so gebildeten Kastenprofils gegebenenfalls mit Isoliermaterial und/oder einem Versteifungsaufbau versehen ist und gegebenenfalls in einem Deckblatt eine von der Falzfläche abstehende Falzleiste ausgebildet ist.The invention relates to a door consisting of two cover sheets connected to one another on at least one rebate surface of the door via a U-shaped connecting profile, the inside of the box profile thus formed optionally being provided with insulating material and / or a stiffening structure and optionally in a cover sheet folding strip protruding from the folding surface is formed.

Bei Türen dieser Art werden die beiden Deeckblatter, die üblicherweise aus Blech bestehen, meistens miteinander verschweißt. Hierzu sind einerseits besondere Geräte erforderlich, andererseits wird die Blechoberfläche beim Schweißen ungünstig beeinflußt. Vor allem bei oberflächenveredelten, z.B. kunststoffbeschichteten Blechen oder bei Blechen aus rostfreiem Stahl sollte das Schweißen absolut vermieden werden.In doors of this type, the two cover sheets, which usually consist of sheet metal, are usually welded together. This requires special equipment on the one hand, and on the other hand the sheet metal surface is adversely affected during welding. Especially with surface refined, e.g. plastic-coated metal sheets or stainless steel sheets should be avoided at all costs.

Bei mit Isoliermaterial gefüllten Türen der gegenständlichen Bauweise, die als Brandschutztüren Verwendung finden, tritt im Brandfall meist eine verschiedene Erwärmung der beiden Deckblätter auf, so daß zufolge der unterschiedlichen Ausdehnung der Bleche eine Verwölbung der Tür eintritt. Um dennoch die Tür im Stock zu halten und einen Durchtritt der Flammen zu verhindern, werden die Türen in der Praxis an einer Seite von mindestens drei Türbändern und an der anderen Seite von einer Schloßanlage mit mindestens drei Fallen gehalten. Ein derartiger Aufbau ist wegen der hohen Kosten nicht wünschenswert.In the case of doors of this construction filled with insulating material, which are used as fire protection doors, different heating of the two cover sheets usually occurs in the event of a fire, so that, due to the different expansion of the sheets, the door warps. In order to keep the door on the floor and prevent the flames from penetrating, the doors are in practice on one side of at least three door hinges and on the other side held by a lock system with at least three latches. Such a structure is not desirable because of the high cost.

Es ist eine Tür bekanntgeworden (DE-OS 19 07 188), die als Kastenprofil aus Blech aufgebaut ist. Ein aus U-Eisen oder Rechteckstahlrohr ausgebildeter Rahmen soll eine einfache Falzbildung ermöglichen, wobei die Falze der Bleche jeweils in den Ebenen der Türblattoberflächen liegen. Bei dieser Tür kann im Brandfall weder eine Verwölbung des Türblattes verhindert, noch ein verminderter Wärmeübergang im Bereich der Falzflächen vermieden werden.A door has become known (DE-OS 19 07 188), which is constructed as a box section made of sheet metal. A frame made of U-iron or rectangular steel tubing is intended to enable simple fold formation, the folds of the metal sheets each lying in the planes of the door leaf surfaces. In the event of a fire, this door can neither prevent the door leaf from warping nor prevent a reduced heat transfer in the area of the rebate surfaces.

Es ist ein Ziel der Erfindung, eine Tür zu schaffen, die frei von den angeführten Nachteilen ist. Dieses Ziel läßt sich mit einer Tür der eingangs genannten Art erreichen, bei welcher erfindungsgemäß die beiden Deckblätter unter Bildung von Randstreifen der Falzfläche jeweils um 90° umgebogen und die Randstreifen über das U-förmige Verbindungsprofil miteinander verbunden sind.It is an object of the invention to provide a door which is free from the disadvantages mentioned. This goal can be achieved with a door of the type mentioned, in which, according to the invention, the two cover sheets are each bent through 90 ° to form edge strips of the folded surface and the edge strips are connected to one another via the U-shaped connecting profile.

Es hat sich gezeigt, daß das U-förmige Verbindungsprofil im Brandfall die auftretenden Verformungsspannungen so weit aufnehmen kann, daß ein starkes Verwölben der Tür unterbleibt. Auch werden durch die Verwendung des U-förmigen Profils die Verbindungsstellen der beiden Türhälften in das Innere des Kastenprofils gelegt, was sowohl in ästhetischer als auch in technischer Hinsicht vorteilhaft ist.It has been shown that the U-shaped connection profile in the event of fire can absorb the deformation stresses to such an extent that the door does not bulge excessively. Also, the connection points of the two door halves are placed in the interior of the box profile through the use of the U-shaped profile, which is advantageous both aesthetically and technically.

Besonders zweckmäßig ist es, wenn die Verbindung zwischen jedem Schenkel des U-förmigen Verbindungsprofils und den Randstreifen als Schnappverbindung ausgebildet ist, da in diesem Fall jedes Schweißen, Nieten etc. entfällt, und die Türen durch einfaches Zusammenstecken vorgefertigter Profilteile herstellbar sind.It is particularly expedient if the connection between each leg of the U-shaped connecting profile and the edge strips is designed as a snap connection, since in this case no welding, riveting etc. is required, and the doors are pre-selected by simply plugging them together finished profile parts can be produced.

Eine sehr brauchbare und mechanisch feste Ausbildung der Schnappverbindung erhält man, wenn die Endbereiche der Schenkel des U-förmigen Verbindungsprofils unter Bildung eines Haltesteges um etwa 1800 nach innen umgekantet sind und jeder Randstreifen ein zum Türumfang hin offenes Schlitzprofil mit einem nach innen weisenden Haltesteg aufweist.A very useful and mechanically strong design of the snap connection is obtained when the end portions of the legs are folded over the U-shaped connection profile to form a holding web approximately 180 0 inwards and each edge strip has a to the door periphery, open slotted profile with an inwardly pointing retaining web .

Es ist aber ebensogut möglich, daß die Schenkel des U-förmigen Verbindungsprofils unter Bildung eines zum Türumfang hin offenen Schlitzprofils abgekantet sind, wobei im Endbereich der Schenkel Haltestege ausgebildet sind, und die Randstreifen einen um 90° nach innen abgewinkelten Steg aufweisen, dessen Endbereiche unter Bildung eines Haltesteges um 180° nach innen abgekantet sind.However, it is equally possible that the legs of the U-shaped connecting profile are folded to form a slot profile that is open towards the door circumference, with retaining webs being formed in the end region of the legs, and the edge strips having a web angled inwards by 90 °, the end regions of which are below Formation of a holding bridge are bent inwards by 180 °.

Falls in der Basis des U-förmigen Verbindungsprofils eine durchgehende, nach innen verlaufende Nut vorgesehen ist, können in dieser Nut beispielsweise Tärbänder oder Schloßstulpe untergebracht werden. Überdies vermag ein so ausgestaltetes Verbindungsprofil in den Deckblättern auftretende Spannungen besonders gut aufzunehmen.If a continuous, inwardly extending groove is provided in the base of the U-shaped connection profile, for example tarpaulins or lock cuffs can be accommodated in this groove. In addition, a connection profile designed in this way can absorb stresses occurring particularly well in the cover sheets.

Die Erfindung samt ihren weiteren Merkmalen und Vorteilen ist im folgenden an Hand beispielsweiser Ausführungsformen näher erläutert, die in der Zeichnung veranschaulicht sind. Es zeigen

  • Figur 2 bis 5 je eine Ausführungsform der Erfindung in einem Schnitt nach der Linie A-A der Fig. 1.
The invention together with its further features and advantages is explained in more detail below on the basis of exemplary embodiments which are illustrated in the drawing. Show it
  • Figure 1 is a front view of a door and
  • 2 to 5 each an embodiment of the invention in a section along the line AA of FIG. 1st

Gemäß Fig. 1 und 2 ist das Türblatt 1 einer Tür an einem Zargenrahmen 2 mittels zweier Scharniere angelenkt. Das Türblatt 1 besteht aus zwei Deckblättern 3, 4, die an ihrer Berandung unter Bildung von Randstreifen 7,8 abgewinkelt und über ein U-förmiges Verbindungsprofil 5 miteinander verbunden sind. Der Innenraum des so gebildeten Kastenprofils ist mit Isoliermaterial 6 gefüllt; er kann jedoch auch einen Versteifungsaufbau mit oder ohne Isolierung enthalten.1 and 2, the door leaf 1 of a door is hinged to a frame frame 2 by means of two hinges. The Door leaf 1 consists of two cover leaves 3, 4, which are angled at their edges to form edge strips 7, 8 and are connected to one another via a U-shaped connecting profile 5. The interior of the box section thus formed is filled with insulating material 6; however, it can also include a stiffening structure with or without insulation.

Die Verbindung zwischen dem Verbindungsprofil 5 und den beiden Randstreifen 7 ist als formschlüssige Schnappverbindung ausgebildet. Zu diesem Zweck schließt an den abgewinkelten Randstreifen 7,8 jedes Deckblattes 3,4 ein zum Türumfang hin offenes Schlitzprofil 9, 10 mit einem nach innen weisenden Haltesteg 11, 12 an. Die Endbereiche der Schenkel 13, 14 des U-förmigen Verbindungsprofils 5 sind unter Bildung eines Haltestegs 15, 16 um etwa 180° nach innen umgekantet.The connection between the connecting profile 5 and the two edge strips 7 is designed as a positive snap connection. For this purpose, the angled edge strips 7, 8 of each cover sheet 3, 4 are followed by a slot profile 9, 10 that is open toward the door circumference and has an inwardly pointing retaining web 11, 12. The end regions of the legs 13, 14 of the U-shaped connecting profile 5 are folded inwards by approximately 180 ° to form a retaining web 15, 16.

Beim Zusammensetzen des Türblattes 1 aus den Deckblättern 3, 4 und dem Verbindungsprofil 5 werden die Schenkel 13, 14 des Profils 5 in die Sehlitzprofile 9, 10 eingeschoben. Hierbei federt das Schlitzprofil 9, 10 zunächst etwas auf, schnappt jedoch wieder in seine ursprüngliche Lage, sobald die Haltestege 15, 16 die Haltestege 11, 12 passiert haben. In der gezeigten Stellung ist das Verbindungsprofil bereits eingeschnappt.When assembling the door leaf 1 from the cover sheets 3, 4 and the connecting profile 5, the legs 13, 14 of the profile 5 are inserted into the Sehlitz profiles 9, 10. Here, the slot profile 9, 10 initially springs open somewhat, but snaps back into its original position as soon as the holding webs 15, 16 have passed the holding webs 11, 12. In the position shown, the connection profile is already snapped into place.

Die erfindungsgemäße Verbindung der beiden Deckblätter erlaubt eine besonders rationelle Montage, da die üblichen Arbeiten, wie Schweißen, Nieten, Kleben etc. entfallen. Es soll an dieser Stelle erwähnt werden, daß die Deckblätter nicht nur aus Metallblechen hergestellt sein können. Vielmehr kommen auch andere geeignete Werkstoffe, welche die Ausbildung der genannten Schnappverbindung erlauben, insbesondere Kunststoffe, zur Herstellung der Deckblätter und des Verbindungsprofils in Frage. Besondere Vorteile bietet die Erfindung im Zusammenhang mit Brandschutztüren, die gemäß der Erfindung z.B. aus Stahlblechen und unter Verwendung einer geeigneten, hochwärmefesten Isolierung hergestellt werden. Der Wärmeübergang zwischen den beiden Deckblättern wird nämlich durch die besondere Art der Verbindung erheblich erschwert, so daß die Erwärmung der dem Feuer abgewandten Türseite in Grenzen bleibt. Außerdem bietet die Verbindung mit Hilfe des Verbindungsprofils die Möglichkeit, die bei üblichen Türen im Brandfall auftretende Verwölbung der Tür weitgehend zu verhindern. Der Grund hierfür liegt darin, daß sich das vom Feuer erwärmte Deckblatt zunächst ungehindert ausdehnen kann, da diese Formänderung von dem immer vorhandenen Spiel der Verbindung zwischen den Deckblättern und dem Verbindungsprofil aufgenommen wird. Außerdem können die Schenkel des Verbindung sprofils um ein gewisses Maß verbogen werden bzw. sich schräg stellen, bevor es zu einem Verwölben der Tür kommt.The connection of the two cover sheets according to the invention allows a particularly efficient assembly, since the usual work, such as welding, riveting, gluing, etc. is eliminated. It should be mentioned at this point that the cover sheets can not only be made of sheet metal. Rather, other suitable materials which allow the formation of the snap connection mentioned, in particular plastics, are also suitable for producing the cover sheets and the connection profile. The invention offers particular advantages in connection with fire protection doors which, according to the invention, are produced, for example, from sheet steel and using a suitable, highly heat-resistant insulation. The heat transfer between the two cover sheets is made considerably more difficult by the special type of connection, so that the heating of the side of the door facing away from the fire remains limited. In addition, the connection with the aid of the connection profile offers the possibility of largely preventing the door from buckling in the event of a fire in the event of a fire. The reason for this is that the cover sheet heated by the fire can initially expand unhindered, since this change in shape is absorbed by the always present play of the connection between the cover sheets and the connection profile. In addition, the legs of the connection profile can be bent to a certain extent or tilt before the door warps.

Bei der in Fig. 2 dargestellten Ausführungsform der Erfindung ist in der Basis des U-förmigen Verbindungsprofils 5 eine durchgehende, nach innen verlaufende Nut 17 ausgehildet. Dadurch wird einerseits die Elastizität des Profils weiter erhöht, so daß die erwähnte Formänderung eines erhitzten Deckblattes besser aufgenommen werden kann, andererseits kann in dieser Nut z.B. der Stulp eines Schlosses untergebracht, d.h. versenkt angeordnet werden. Gleiches gilt auch für die Befestigung von Türbändern.In the embodiment of the invention shown in FIG. 2, a continuous, inwardly extending groove 17 is formed in the base of the U-shaped connecting profile 5. This on the one hand further increases the elasticity of the profile, so that the aforementioned change in shape of a heated cover sheet can be better absorbed, on the other hand e.g. the faceplate of a lock, i.e. be sunk. The same applies to the fastening of door hinges.

Der Fig. 3 ist eine andere Variante der Erfindung zu entnehmen, bei welcher die Schenkel 13, 14 des Verbindungsprofils 5 unter Bildung eines zum Türumfang hin offenen Schlitzprofils 18, 18a abgekantet sind. Im Endbereich der Schenkel sind wiederum Haltestege 19, 20 ausgebildet. Von den Randstreifen 7, 8 der Deckblätter 3, 4 verlaufen abgewinkelte Stege 21, 22 etwa parallel zu den Deckblättern nach innen. Die Endbereiche der Stege sind unter Bildung von Haltestegen 23, 24 um ca. 1800 nach innen abgekantet. Der Aufbau der Schnappverbindung ist folglich analog zu dem in Fig. 2 gezeigten Aufbau,und die Wirkungsweise ist die gleiche.3 shows another variant of the invention, in which the legs 13, 14 of the connecting profile 5 are bent to form a slot profile 18, 18a that is open toward the door circumference. Retaining webs 19, 20 are in turn formed in the end region of the legs. From the margin strips 7, 8 of the cover sheets 3, 4 run angled webs 21, 22 approximately parallel to the cover sheets to the inside. The end regions of the webs are bent to form holding webs 23, 24 to about 180 0 inward. The structure of the snap connection is consequently analogous to the structure shown in FIG. 2, and the mode of operation is the same.

Die in Fig. 4 gezeigte Ausführungsform der Erfindung entspricht der in Fig. 2 gezeigten, jedoch ist hier in einem Deckblatt 4 ein üblicher Türfalz 25 ausgebildet. Während bei den Ausführungen nach Fig. 2 und 3 beide Deckblätter in rationeller Weise identisch ausgebildet werden können, bedingt die Herstellung des Türfalzes 25 zwei verschieden gestaltete Deckblätter 3, 4.The embodiment of the invention shown in FIG. 4 corresponds to that shown in FIG. 2, but here a conventional door rebate 25 is formed in a cover sheet 4. 2 and 3, both cover sheets can be designed identically in a rational manner, the production of the door rebate 25 requires two differently designed cover sheets 3, 4.

Schließlich ist in Fig. 5 gezeigt, daß die Verbindung zwischen den Randstreifen der Deckblätter 3 und 4 und dem Verbindungsprofil 5 nicht notwendigerweise als Schnappverbindung ausgestaltet sein muß. Das Verbindungsprofil 5 kann U-förmig gestaltet sein, wobei seine Schenkel 13, 14 in ein Schlitzprofil 9 bzw. 10 der Randstreifen eingreifen. Diese Ausführung entspricht einer vereinfachten Ausführungsform nach Fig. 2, bei welcher die Haltestege 11, 12 und 15, 16 weggelassen sind.Finally, it is shown in FIG. 5 that the connection between the edge strips of the cover sheets 3 and 4 and the connection profile 5 does not necessarily have to be designed as a snap connection. The connecting profile 5 can be U-shaped, its legs 13, 14 engaging in a slot profile 9 or 10 of the edge strips. This embodiment corresponds to a simplified embodiment according to FIG. 2, in which the holding webs 11, 12 and 15, 16 are omitted.
