Abstract

This is esp. for profiled sheets used in steel cell ceilings, with thrust-transmitting butt connections at their U-bent edges with no overlapping. The V-shaped incisions are cut simultaneously vertically in both edges at a joint, the triangular flaps being bent sideways and outwards and back against the edge surfaces, pref. alternately on either side of the joint. A steel cell ceiling comprising these may have longitudinal adjoining edges clamped together by means of sheet lugs, formed from the material in the V incisions. The connections can be made by one man working alone, with a cutting and shaping tool.

Nietlose, schubübertragende Verbindung von Profilblechen.Rivetless, shear-transferring connection of profiled sheets.

Die Erfindung betrifft ein Verfahren zur Herstellung nietloser, schubübertragender Verbindungen von Profilblechen, insbesondere Trapezblechen, und nach diesem Verfahren hergestellte Verbindungen, insbesondere für Stahlzellendecken aus solchen Blechen.The invention relates to a method for producing rivetless, shear-transmitting connections of profiled sheets, in particular trapezoidal sheets, and connections produced by this method, in particular for steel cell ceilings from such sheets.

Im Stahlskelettbau werden Stahlzellendecken verwendet, die aus an ihren Rändern ü-förmig aufgebogenen Profilblechen zusammengesetzt sind. Diese Profilbleche liegen nebeneinander auf Trägern auf und bilden mit ihrer U-Basis die Decke, während die aneinanderliegenden U-Schenkel, von denen der eine häufig gegenläufig zurückgebogen über den Nachbarschenkel des anderen Profilbleches greift, als Überdeckungsflächen zur Übertragung von Schubkräften miteinander verbunden werden. In steel frame construction, steel cell ceilings are used, which are made of profiled sheets bent up at their edges in a U-shape are composed. These profile sheets lie next to each other on beams and form the ceiling with their U-base, while the adjacent U-legs, of which the one that is often bent back in opposite directions over the neighboring leg of the other profiled sheet engages as overlapping surfaces be connected to each other for the transmission of shear forces.

Bleche greift und deren Zangenmaul einerseits mit einer Zunge und. andererseits mit zwei Backen ausgestattet ist, wobei die scherenen Seitenkanten dieser Zunge und Backen sich gegenüberstehen und die Backen zwischen sich einen Durchlaß freilassen, in den die Zunge beim Schließen der Zange eintaucht (DBGM Λ 993 916). Die Zange stellt an den einseitig zugänglichen Überdeckungsflächen der Profilbleche schubübertragende Stanzverbindungen in Form ausgescherter Schlaufen her, mit denen sich die Profilbleche von Stahlzellendecken zu schubsteifen Scheiben zusammenschieben lassen, die das Gebäude gegen horizontale Schubbeanspruchungen sichern, ohne daß die sonst üblichen Windverbände erforderlich sind.Sheet metal grabs and their jaws on the one hand with a tongue and. on the other hand, it is equipped with two jaws, the scissor side edges of this tongue and jaws facing each other and the jaws leaving a passage between them, into which the tongue dips when the pliers are closed (DBGM Λ 993 916). The pliers produce thrust-transmitting punched connections in the form of sheared loops on the overlapping surfaces of the profiled sheets, which are accessible from one side, with which the profiled sheets can be pushed together from steel cell ceilings to shear-resistant panes that secure the building against horizontal shear stresses without the need for the otherwise usual wind bracing.

Diese bekannte nietlose, schubübertragende Verbindung ist bei Profilblechen, die sich an den Längsstößen nicht übergreifen, nicht anwendbar, weil sich die Schlaufen im Schenkel des einen Bleches, die in die fensterförmigen Ausschnitte im Schenkel des anderen Bleches hineingezogen sind, beim Auseinanderrücken der gestoßenen Bleche aus den Fenstern lösen können.This well-known rivetless, shear-transmitting connection is used in profile sheets that do not overlap at the longitudinal joints, not applicable because the loops in the leg of one sheet metal that are in the window-shaped cutouts in the Legs of the other sheet are pulled in when moving apart the butted metal sheets can detach from the windows.

Die Erfindung stellt sich daher die Aufgabe, eine nietlose, schubübertragende Verbindung für Profilbleche zu schaffen, die am Längsstoß mit ihren U-förmig aufgebogenen Rändern stumpf, d.h. ohne Überlappung aneinandergestoßen sind..The invention therefore has the task of providing a rivetless, To create thrust-transmitting connection for profile sheets, the U-shaped edges on the longitudinal joint butt, i.e. butt against each other without overlapping ..

Eine solche Verbindung läßt sich mit dem Verfahren nach der Erfindung schaffen, bei dem die beiden Ränder eines Stoßes in Abständen zugleich im, wesentlichen senkrecht zur Randkante eingeschnitten werden und der Einschnitt V-förmig erweitert wird, indem beiderseits des Einschnitts dreieckförmige Lappen beider Bleche seitlich heraus- und gegen die Randflächen zurückgebogen werden. Die einzelnen Verfahrensschritte werden in einem Arbeitsgang mittels eines Schneid- Such a connection can be created with the method according to the invention, in which the two edges of a joint at intervals at the same time essentially perpendicular to the marginal edge are incised and the incision is widened V-shaped by triangular-shaped on both sides of the incision The flaps of both sheets can be bent out to the side and back against the edge surfaces. The individual process steps are carried out in one operation by means of a cutting

und Formwerkzeuges ausgeführt, das von einem Mann bedient und ähnlich der bekannten Zange von oben angesetzt wird und beide Stoßränder zugleich erfaßt, einschneidet und falzt.and executed molding tool, which is operated by a man and applied from above similar to the known pliers and both abutment edges are grasped, cut and creased at the same time.

Besonders vorteilhaft werden die beiden Lappen seitlich eines Einschnitts wechselständig auf Qe eine Seite des Stoßes zurückgebogen; hierdurch entsteht eine formschlüssige Verbindung, die alle Schubkräfte überträgt, gleichgültig in welcher Richtung sie auftreten.It is particularly advantageous if the two flaps on the side of an incision are alternate on one side of the Butt bent back; this creates a form-fitting connection that transmits all shear forces, indifferently in which direction they occur.

Gegenstand der Erfindung ist zugleich eine Stahlzellendecke aus mit ihren U-förmig aufgebogenen Längsrändern stumpf gestoßenen Profilblechen, insbesondere Trapezblechen, bei der erfindungsgemäß die Längsränder der Stöße in Abständen mittels gefalzter Blechfahnen miteinander verklammert sind, die aus dem Material V-förmiger Ausnehmungen in Längsrändern durch Verformung gewonnen sind.The invention also relates to a steel cell ceiling made of butt-butted longitudinal edges that are bent up in a U-shape Profiled sheets, in particular trapezoidal sheets, in which, according to the invention, the longitudinal edges of the joints are spaced apart by means of folded sheet metal flags are clamped together, which are made of the material of V-shaped recesses in longitudinal edges are obtained by deformation.

Zur Erläuterung der Erfindung ist in der Zeichnung der Längsstoß zweier Trapezprofilbleche in perspektivischer Ansicht dargestellt.To explain the invention, the longitudinal joint of two trapezoidal profile sheets is shown in perspective view in the drawing shown.

Die beiden Profilbleche 1, 2, von denen Blech 2 aus Gründen besserer Übersichtlichkeit nur angedeutet ist, sind mit ihren U-förmig aufgebogenen Rändern 1.1 und 1.2 stumpf aneinandergestoßen. Die Ränder sind von den Kanten her in Abständen, die ge nach Blechstärke und auftretenden Kräften vorzugsweise zwischen 100 und 500 mm liegen auf eine Tiefe von 1/3 bis 2/5 der Randhöhe eingeschnitten, und die Randpartien des Einschnitts sind als dreieckförmige Lappen 3 seitlich heraus und gegen die Randflächen zurückgebogen - und zwar (in der Ansicht der Zeichnung) links gegen den Rand 1.2 des Bleches 2 und rechts gegen den Rand 1.1 des Bleches 1 -, so daß in der Doppelkante des Längsstoßes eine V-förmige Ausnehmung entsteht. Der Spitzenwinkel dieser AusnehmungThe two profile sheets 1, 2, of which sheet 2 is only indicated for reasons of clarity, are with their U-shaped upturned edges 1.1 and 1.2 butted together. The edges are spaced from the edges, preferably depending on the thickness of the sheet and the forces that occur between 100 and 500 mm are cut to a depth of 1/3 to 2/5 of the edge height, and the edge parts of the incision are bent out laterally as triangular flaps 3 and against the edge surfaces - and although (in the view of the drawing) on the left against the edge 1.2 of the sheet 2 and on the right against the edge 1.1 of the sheet 1 -, so that a V-shaped recess is created in the double edge of the longitudinal joint. The point angle of this recess

beträgt im Beispiel 60°. Man erkennt, daß die beiden Profilbleche 1 und 2 in der Berührungsebene formschlüssig miteinander verbunden sind und die Verbindung nicht nur alle in dieser Ebene auftretende Kraftvektoren überträgt, sondern auch ein Aufklaffen des Stoßes durch Auseinanderrücken der Bleche verhindert.is 60 ° in the example. It can be seen that the two profile sheets 1 and 2 form-fit with one another in the plane of contact are connected and the connection not only transmits all force vectors occurring in this plane, but also a gaping of the joint is prevented by moving the sheets apart.
