Die Erfindung betrifft eine Stahlblechtür, insbesondere in Feuerschutz¬ ausbildung, mit einem die eine Türblattbreitseite bildenden Kasten und einem die andere Türblattbreitseite bildenden Deckel, der an seinen Randbereichen mit parallel zur Breitseitenebene nach außen abragenden Randstreifen der Kastenränder - insbesondere durch Punktschweißen - verbunden ist, wobei ein an die Verbindungszone nach außen an¬ schließender Randabschnitt der Randbereiche des Deckels oder der Randstreifen der Kastenränder zur Bildung des Anschlagbereiches eines Falzes auf den Kasten zu gerichtet abgewinkelt ist und die Verbin¬ dungszone übergreift.The invention relates to a sheet steel door, in particular in fire protection training, with a box forming the door leaf broad side and a cover forming the other door leaf broad side, which is connected at its edge regions to edge strips of the box edges projecting outwards parallel to the broad side plane, in particular by spot welding, whereby an edge section of the edge regions of the lid or the edge strips of the box edges adjoining the connection zone to the outside is angled to form the stop area of a fold toward the box and overlaps the connection zone.
Türkonstruktionen dieser Art sind bekannt, und zwar sowohl in Dünn¬ falz- als auch in Dickfalzausführung. Bei einer Dünnfalztür wird der die an den Rändern des Kastens nach außen abstrebend abgebogenen Randstreifen übergreifende Deckel in diesem Übergriffsbereich punkt¬ verschweißt, so daß sich ein entsprechend der Tiefe des Kastens dik- kes Türblatt ergibt. Der Deckel weist eine ursprüngliche Ausdehnung auf, die über die Randstreifen des Kastens hinausgeht, und zwar in Form von Randabschnitten, die nach der Punktverschweißung um 180° auf die Randstreifen des Kastens zurückgebogen werden. Dadurch er¬ gibt sich im Falzbereich eine dreilagige Ausbildung geringer Dicke, wo- bei die umgebogenen Randabschnitte des Deckels die Punktschweißzo¬ nen der Verbindung zwischen den Randstreifen des Kastens und den Randbereichen des Deckels übergreifen. Ein solches Vorgehen ist in Fi¬ gur 2 schematisch wiedergegeben.Door constructions of this type are known, both in thin rebate and in thick rebate designs. In the case of a thin rebate door, the cover which overlaps the edge strips which are bent off towards the outside at the edges of the box is spot welded in this overlapping area, so that a door leaf corresponding to the depth of the box is obtained. The lid has an original extension that extends beyond the edge strips of the box, in the form of edge sections that are bent back after the spot welding by 180 ° onto the edge strips of the box. This results in a three-layer design of small thickness in the fold area, which in the case of the bent-over edge sections of the cover, the spot welding zones of the connection between the edge strips of the box and the edge areas of the cover overlap. Such a procedure is shown schematically in FIG. 2.
Eine Dickfalztür herkömmlicher Ausbildung besteht ebenfalls aus einem Kasten und einem Deckel, wobei der Kasten bei übereinstimmender Dicke mit derjenigen der Dünnfalzausbildung etwa um die Falzdicke weniger tief ausgebildet ist. Der Deckel weist in seinen den Kasten überragenden Randbereichen einen aus der Deckelebene rechtwinklig abgebogenen Steg und daran anschließend einen auf den Kasten zu gerichtet abgewinkelten Anschlagbereich auf, der die Randstreifen des Kastens übergreift und mit seiner frei auslaufenden Kante in den Win¬ kelbereich zwischen dem Kastenkörper und dessen Randstreifen ein¬ greift. Hier findet ein Heftschweißen statt, was wegen der dabei mögli¬ chen Schweißspritzer und Abbrand nachteilig ist. Besonders umständ¬ lich und daher fertigungstechnisch mühsam ist vor allem die Tatsache, daß bei der vorgeschilderten Dickfalztür der in seinen Randbereichen gefalzte Deckel in die Verschweißposition mit dem Kasten nur durch ein in Längsrichtung der Randbereiche stattfindendes Verschieben überführt werden kann, d.h. bei einer Türhöhe von 2 m ein entspre¬ chend raumaufwendiger und unhandlicher Vorgang. Diese Herstel¬ lungsweise ergibt sich schematisch aus Figur 3.A thick rebate door of conventional design also consists of a box and a cover, the box being designed to be less deep by approximately the fold thickness if the thickness matches that of the thin rebate design. The lid has in its edge areas protruding from the box a web bent at right angles from the lid plane and then a stop area angled towards the box, which engages over the edge strips of the box and with its freely tapering edge into the angle area between the box body and the edge strip engages. Here, tack welding takes place, which is disadvantageous because of the possible welding spatter and burn-up. What is particularly cumbersome and therefore laborious in terms of production technology is the fact that, in the case of the above-described thick rebate door, the lid folded in its edge regions can only be brought into the welding position with the box by moving it in the longitudinal direction of the edge regions, i.e. with a door height of 2 m, this is a correspondingly space-consuming and unwieldy process. This method of manufacture is shown schematically in FIG. 3.
Der Erfindung liegt die Aufgabe zugrunde, eine Dickfalztür aus Kasten und Deckel zur Verfügung zu stellen, die sich wesentlich einfacher handhaben läßt und hinsichtlich der Verbindungsart zwischen Kasten und Deckel weniger Probleme bereitet.The invention has for its object to provide a thick rebate door made of box and lid, which is much easier to handle and less problems with regard to the type of connection between the box and lid.
Ausgehend von einer Stahlblechtür mit den eingangs genannten Merk¬ malen wird diese Aufgabe dadurch gelöst, daß der Randabschnitt eine erste, einen in seiner Breite die Dicke des Falzes bestimmenden Steg bildende Abwinkelung und daran eine zweite, den Anschlagbereich bil- dende Abwinkelung aufweist, die die Verbindungszone in etwa Steg¬ breite beabstandet übergreift.Starting from a sheet steel door with the features mentioned at the outset, this object is achieved in that the edge section forms a first bend forming a web that determines the thickness of the fold in width, and then a second bend forming the stop area. has an ending bend which overlaps the connecting zone at a spacing of approximately web width.
Die erfindungsgemäße Ausbildung der Dickfalz-Stahlblechtür geht von dem Gedanken aus, ein hinsichtlich der Handhabung und insbesondere auch vor Korrisionen schützendes Punktschweißen dadurch zu ermögli¬ chen, daß der Deckel hinsichtlich seines vorgefalzten Randbereiches zunächst nicht völlig in seine endgültig abgewinkelte Ausgestaltung überführt wird, so daß die Verbindungszone zwischen Randstreifen des Kastens und Randbereich des Deckels senkrecht dazu nach Auflegen des Kastens auf den Deckel zugänglich ist, wodurch sich ein Punkt¬ schweißgerät entsprechend ansetzen läßt. Erst nach erfolgter Punkt- schweißung wird die vorbereitet gefalzte Anschlagzone des Deckels weiter auf den Kasten zu gebogen, so daß der Anschlagbereich des Falzes die punktgeschweißte Verbindungszone zwischen Randstreifen des Kastens und Randbereich des Deckels mit Abstand abdeckend übergreift.The design of the thick rebated sheet steel door according to the invention is based on the idea of enabling spot welding with regard to handling and in particular also to protect against corrosion by initially failing to completely convert the cover into its finally angled configuration with regard to its pre-folded edge region, so that the connection zone between the edge strip of the box and the edge region of the lid is accessible perpendicularly thereto after the box has been placed on the lid, so that a spot welding device can be attached accordingly. Only after spot welding has been carried out is the prepared, folded stop zone of the lid further bent onto the box, so that the stop area of the fold overlaps the spot welded connection zone between the edge strips of the box and the edge area of the lid.
Erfindungsgemäß erreicht man, daß die Verbindung zwischen Deckel und Kasten durch Punktschweißen ermöglicht wird und daß man mit einem einfachen Auflegen des Kastens auf den Deckel bzw. umgekehrt auskommt und damit ein lästiges Zusammenschieben von Kasten und vorgeformtem Deckel vermeidet.According to the invention it is achieved that the connection between the lid and the box is made possible by spot welding and that one can do with a simple placing of the box on the lid or vice versa and thus avoids the annoying pushing together of the box and the preformed lid.
Es ist grundsätzlich denkbar, die Falzausbildung mit Steg und An¬ schlagfläche an dem Kasten bzw. im Anschluß an dessen Randstreifen auszubilden, bevorzugt geschieht dies jedoch im Bereich des Deckels, weil damit auch die freie Kante des Randstreifens des Kastens mitüber¬ griffen wird.It is fundamentally conceivable to form the fold with a web and stop surface on the box or in connection with its edge strip, but this is preferably done in the area of the cover, because this also overlaps the free edge of the edge strip of the box.
Aus Figur 1 der beiliegenden Zeichnung ist schematisch und nur hin¬ sichtlich eines Randbereiches einer Stahlblechtür die erfindungsgemäße Ausbildung als Beispiel wiedergegeben. Der insgesamt mit 1 bezeichnete Kasten weist an seinen Rändern pa¬ rallel zur Türebene nach außen abstrebende Randstreifen 4 auf, die flä¬ chig mit Randbereichen 3 des Deckels 2 des Türblattes angreifen, so¬ bald Deckel und Kasten in die Verbindungsposition überführt sind. Die¬ sen Zustand zeigt die linke Abbildung der Figur 1. In diesem Zustand wird zwischen Randstreifen 4 des Kastens 1 und Randbereichen 3 des Deckels 2 eine Punktverschweißung durchgeführt; dies ist durch ent¬ sprechend schematisierte Werkzeugwiedergabe in diesem linken Bild¬ teil angezeigt.The design according to the invention is shown as an example from FIG. The box, identified overall by 1, has on its edges parallel to the door plane outwardly striving edge strips 4 which engage flatly with edge regions 3 of the cover 2 of the door leaf as soon as the cover and box are transferred into the connecting position. This state is shown on the left in FIG. 1. In this state, spot welding is carried out between edge strips 4 of the box 1 and edge regions 3 of the lid 2; this is indicated by correspondingly schematized tool reproduction in this left part of the figure.
Man ersieht aus dem linken Bildteil, daß der Randbereich 3 des Deckels 2 in seinem nach außen über die Verbindungszone anschließenden Randabschnitt 6 zur Bildung eines Dickfalzes vorgefalzt ist, und zwar anschließend an die Verbindungszone mit einem Steg 8 und einem rechtwinklig daran anschließenden Anschlagbereich 9, der in einem wiederum und zwar um mehr als 90° abgewinkelten Versteifungsrand 10 endet, der der Verbindungszone 5 - Punktschweißzone - zugewandt ist. Aus dem linken Bildteil erkennt man, daß der die Dicke des Falzes in etwa bestimmende Steg 8 nur um einen Winkel kleiner 90° vorbe¬ reitend gegenüber der Deckelebene angebogen ist, so daß das Punkt¬ schweißwerkzeug die Verbindungszone zwischen Deckel und Kasten mühelos erreichen kann. Nach erfolgter Punktschweißung wird dann der Randabschnitt 6 des Randbereiches 3 des Deckels 2 in seine end¬ gültige Lage weitergebogen, derart, daß der Steg 8 rechtwinklig zur Deckelebene abgebogen ist. Es ergibt sich die aus dem rechten Bildbe¬ standteil der Figur 1 ersichtliche Konfiguration der Stahlblechtür, in der trotz einfachster und günstigster Herstellung in Handhabung und Ver¬ bindungstechnik ein die Verbindungszone abdeckender Anschlagbe¬ reich des Dickfalzes erreicht ist. It can be seen from the left part of the picture that the edge area 3 of the cover 2 is pre-folded in its edge section 6 adjoining the outside via the connection zone to form a thick fold, specifically after the connection zone with a web 8 and a stop area 9 adjoining it at right angles, the ends in a stiffening edge 10 which is in turn angled by more than 90 ° and faces the connecting zone 5 - spot welding zone. From the left part of the figure it can be seen that the web 8, which roughly determines the thickness of the fold, is only bent by an angle of less than 90 ° in preparation for the cover plane, so that the spot welding tool can effortlessly reach the connection zone between the cover and the box. After spot welding has been carried out, the edge section 6 of the edge region 3 of the cover 2 is then bent further into its final position such that the web 8 is bent at right angles to the cover plane. This results in the configuration of the sheet steel door shown in the right part of the figure in FIG. 1, in which, despite the simplest and cheapest manufacture in handling and connection technology, a stop area of the thick rebate covering the connection zone is reached.
