Abstract

The invention relates to a coupling for connecting the load-bearing parts of load-bearing structures, in particular for scaffolding boards, which are to be laid in order to form a close-knit surface of any length and breadth. The invention consists in that end pieces are formed on the surfaces to be connected, the end surfaces of said end pieces being chamfered at the same angle but inversely with respect to one another. The end surfaces form a nose, the shape and size of which correspond to a groove which is located to the rear thereof and is arranged in an inclined manner at the same angle. A positively locking connection is obtained by fitting the nose and groove of the end pieces together.

Die Erfindung betrifft eine Kupplung zur Verbindung von Gerüstbohlen, die zu einer dichten Oberfläche beliebiger Länge und Breite verlegt werden sollen und bei denen an den zu verbindenden Flächen Endstücke vorgesehen sind, die nut- und federartig ineinandergreifen. The invention relates to a coupling for connecting scaffolding planks, which are to be laid to form a dense surface of any length and width and where end pieces are provided on the surfaces to be connected, the groove and interlock like a spring.

Es ist eine Kupplung zur Verbindung von aneinanderstoßenden Belagteilen auf Gerüsten bekannt geworden (DD-PS 56 919), die durch je ein an den Enden zweier zu stoßender Belagteile lösbar angeordnetes Winkelprofil besteht, wobei der Schenkel des einen Winkelprofils auf der Lauffläche des einen Belagteils befestigt und der andere Schenkel parallel zur Stirnfläche des Belagteils einen Zwischenraum bildend angeordnet ist, wobei in diesen Zwischenraum der Schenkel des anderen an dem Belagteil entgegengesetzt befestigten Winkelprofils eingreift. Mit Hilfe aus solchen Verbindungselementen bestehender Kupplungen können Gerüstbeläge so ausgeführt werden, daß sie überdeckungslos und in standardisierten Maßen eingebaut werden können. Diese Kupplungen eignen sich aber nicht dazu, benachbarte Bohlen zu einer gemeinsamen Tragwirkung heranzuziehen, weil sie keine Querkraft übertragen können. It is a coupling for connecting abutting facing parts on scaffolding become known (DD-PS 56 919), which by one at the ends of two there is a detachably arranged angle profile of the facing parts to be abutted, the leg of the one angle profile attached to the tread of a lining part and the other legs parallel to the face of the facing part forming a gap is arranged, with the leg of the other on the covering part in this gap engages oppositely attached angle profile. With the help of such fasteners existing couplings, scaffolding decks can be designed so that they do not overlap and can be installed in standardized dimensions. These couplings are suitable but not to use neighboring planks for a common load-bearing effect, because they cannot transfer any transverse force.

Der Erfindung liegt daher die Aufgabe zugrunde, mit einer Kupplung für Gerüstbohlen die Möglichkeit zu schaffen, die Bohlen miteinander so zu verbinden, daß sie nicht nur dicht aneinander anschließen, sondern auch eine gemeinsam tragende Einheit bilden. The invention is therefore based on the object with a clutch to create the possibility for scaffolding planks to connect the planks to one another in such a way that that they are not only close to one another, but also support one another Form unity.

Zu diesem Zweck wird eine Kupplung mit den im kennzeichnenden Teil des Hauptanspruchs beschriebenen Merkmalen vorgeschlagen. Vorzugsweise sind Nut und Feder unter einem Winkel von 45" geneigt, wodurch günstige Verhältnisse bezüglich der Kraftübertragung geschaffen werden. For this purpose a coupling with the in the characterizing part of the main claim described features proposed. Preferably are groove and spring inclined at an angle of 45 ", creating favorable conditions regarding the power transmission are created.

Die als Kupplung dienenden Endstücke können sich über die gesamte Breite der Bohlen erstrecken. Sie können aber auch aus einzelnen symmetrisch zur Mitte der Bohlen angeordneten Teilstücken bestehen. In Fällen, in denen die Bohlen aus Metall, insbesondere aus Leichtmetall, bestehen, können die Endstücke einen Teil der Bohle selbst darstellen. The end pieces serving as a coupling can extend over the entire Extend width of planks. But you can also from individual symmetrical to There are sections arranged in the middle of the planks. In cases where the planks made of metal, in particular made of light metal, the end pieces can have a Represent part of the screed itself.

In der Zeichnung sind Ausführungsbeispiele des Erfindungsgegenstandes dargestellt, die im folgenden nä- her erläutert werden. Es zeigt F i g. 1 einen Querschnitt durch eine aus einem Leichtmetallprofil bestehende Bohle, F i g. 2 einen Querschnitt durch die Verbindung zweier Bohlen nach Fig. 1, F i g. 3 einen Querschnitt durch die Verbindung zwei er Bohlen, deren Endstücke getrennt von der Bohle hergestellt sind, F i g. 4 einen Querschnitt durch das als Kupplung dienende Endstück einer Holzbohle und F i g. 5 einen Längsschnitt durch zusammengesetzte Bohlen mit Sicherungen gegen seitliches Verschieben. Exemplary embodiments of the subject matter of the invention are shown in the drawing shown in the following are explained here. It shows F i g. 1 shows a cross section by a plank consisting of a light metal profile, FIG. 2 a cross section by connecting two planks according to Fig. 1, F i g. 3 shows a cross section through the connection of two he planks, the end pieces of which are made separately from the plank are, F i g. 4 shows a cross section through the end piece serving as a coupling Wooden plank and f i g. 5 shows a longitudinal section through assembled planks with securing devices against lateral shifting.

Die in F i g. 1 dargestellte Bohle besteht aus einem rechteckigen Kastenprofil, das aus Obergurt 1, Untergurt 2 und senkrechten Stegen 3 gebildet wird und das aus einer Leichtmetallegierung besteht. An den Schmalseiten der Bohle sind Endstücke 4, 5 vorgesehen, die in einem Stück mit der Bohle selbst hergestellt sind und die unter gleichen Winkeln, nämlich unter 45°, jedoch entgegengesetzt zueinander, abgeschrägt sind. Ihre Außenkanten, die sich über die ganze Schmalseite der Bohle erstrecken, bilden eine Feder 6, 7, die eine zwischen ihr und den Grundkörpern 8,9 der Endstücke 4,5 gebildete Nut 10, 11 bildet. Die Federn 6,7 sind so ausgebildet, daß sie jeweils in die entgegengesetzt gerichtete Nut 10,11 der nächsten Gerüstbohle passen, wie dies in F i g. 2 dargestellt ist. Die dort gezeigte kraftschlüssige Verbind dung, die durch den Eingriff der durch die Federn 6, 7 und die Nuten 10, in gebildeten Schrägkupplungen besteht, ermöglicht es, Kräfte sowohl in vertikaler als auch in horizontaler Richtung unmittelbar zu übertragen. The in F i g. 1 shown plank consists of a rectangular Box profile, which is formed from the upper chord 1, lower chord 2 and vertical webs 3 and which consists of a light metal alloy. On the narrow sides of the plank end pieces 4, 5 are provided, which are made in one piece with the screed itself and which are at the same angles, namely at 45 °, but opposite to each other, are beveled. Their outer edges, which extend over the entire narrow side of the plank extend, form a spring 6, 7, the one between it and the base bodies 8,9 the end pieces 4,5 formed groove 10, 11 forms. The springs 6,7 are designed so that they are each in the oppositely directed groove 10, 11 of the next scaffolding plank fit as shown in FIG. 2 is shown. The frictional one shown there Connection created by the engagement of the springs 6, 7 and the grooves 10, consists in formed angular couplings, it enables forces both in vertical as well as to be transmitted directly in the horizontal direction.

Wie aus F i g. 3 ersichtlich, können die als Kupplung dienenden Endstücke 4, 5 der Gerüstbohlen auch getrennt von der Bohle selbst hergestellt sein. Beispielsweise sind bei der in F i g. 3 dargestellten Kupplung die Endstücke 4, 5 mit einem Ansatz 12 versehen, der mit dem Obergurt 13 und dem Untergurt 14 der zugehörigen Bohle kraftschlüssig fest verbunden ist. Das in F i g. 4 dargestellte Endstück 5 für die Verbindung einer aus Holz bestehenden Bohle 18 besteht aus zwei Teilen, nämlich dem mit Feder 7 und Nut 11 versehenen eigentlichen Endstück 5, das mit einem Ansatz 15 in eine entsprechende Nut eines U-förmigen Zwischenstücks ein greift, das wiederum durch Schrauben 16, 17 mit der Holzbohle 18 verbunden ist. As shown in FIG. 3 can be seen, the end pieces serving as a coupling 4, 5 of the scaffolding planks can also be made separately from the plank itself. For example are at the in F i g. 3 coupling shown the end pieces 4, 5 with an approach 12 provided with the upper chord 13 and the lower chord 14 of the associated plank is firmly connected in a non-positive manner. The in Fig. 4 illustrated end piece 5 for the Connection of a wooden plank 18 consists of two parts, viz the actual end piece 5 provided with a tongue 7 and groove 11, which has an approach 15 engages in a corresponding groove of a U-shaped intermediate piece, which in turn is connected to the wooden plank 18 by screws 16, 17.
