Turmkran, Fachwerkmast od. dgl.Tower crane, half-timbered mast or the like.
Die Neuerung betrifft einen Turmkran, Fachwerkmast od. dgl., also eine Vorrichtung, die in Art eines Fachwerkes aufgebaut ist, beispielsweise ein abbaufähiger und durch das Übereinanderfügen einzelner Elemente verlängerungsfähiger Mast, der nach dem Zusammensetzen eine widerstandsfähige Struktur aufweist.The innovation relates to a tower crane, truss mast or the like, that is to say a device that is constructed in the manner of a truss is, for example, a demolishable mast that can be extended by adding individual elements to one another, which according to has a tough structure when assembled.
Derartige Turmkräne, Fachwerkmaste od. dgl. haben Einzelelemente, die gebildet sind Jeweils aus Gurten, Diagonalverstrebungen und Querträger^ die ihrerseits üblicherweise die vier Planebenen eines sogenannten Schusses, also eines Stückes begrenzen, wobei die Einzelschüsse miteinander in ihren Winkeln verbunden sind.Such tower cranes, half-timbered masts or the like have individual elements, which are each formed from belts, diagonal struts and cross members ^ which in turn usually form the four plan levels a so-called shot, i.e. a piece, with the individual shots being connected to one another at their angles.
Zur Herstellung eines solchen Schusses, also eines solchen Abschnittes des Turmes oder des Mastes( werden verschiedene Ausbildungen verwendet, von denen die beiden folgenden die gebräuchlichsten sind:To produce such a shot, i.e. such a section of the tower or the mast ( various designs are used, of which the following two are the most common:
Zum Ersten besteht jeder Schuss aus zwei Fachwerkflächen, die durch Diagonalverstrebungen und Querträger miteinander verbunden werden,First of all, each shot consists of two truss surfaces, which are connected to one another by diagonal struts and cross members will,
-Z--Z-
zum Zweiten besteht jeder Schuss aus zwei einander gegenüberliegenden Fachwerkflachen, die an einer ihrer Seitenkanten die Diagonalverstrebungen und Querträger der betreffenden Seite tragen, die sich ihrerseits an dem Gurt der gegenüberliegenden Fachwerkfläche befestigen lassen, während auf der freien Seite auf dem Gurt lediglich Stützen und Armierungen vorgesehen sind, auf denen sich die Diagonalverstrebungen und Querträger der gegenüberliegenden Fachwerkfläche befestigen lassen.Second, each shot consists of two opposite one another Half-timbered surfaces that on one of their side edges Wear diagonal struts and cross members on the side in question, which in turn are attached to the strap of the opposite side Have the truss surface fastened, while only supports and reinforcements are provided on the free side of the belt, on which the diagonal struts and cross members of the opposite half-timbered area can be attached.
Alle diese Bauelemente zum Aufbauen von Turmkränen, Masten od. dgl. haben den grossen Nachteil, daß wenn der Turm oder der Mast auseinandergenommen ist, die Einzelteile sehr voluminös sind, da die Breite des demontierten Turmes oder Mastes der Breite einer seiner Seiten gleich ist. Dies bringt sehr grosse Schwierigkeiten mit sich, besonders wenn Türme oder Maste großen Querschnittes demontiert und verladen werden sollen, bei denen die Breite der einen Seite die Vorschriftsnormen für den Strassentransport überschreiten. Ausserdem haben die Einzelteile, die die Seitenplatten bilden, die erst durch den Zusammenbau der Schüsse hergestellt werden, den Nachteil, daß sie nicht stabil genug sind und sehr oft Beschädigungen während des Transportes erleiden.All of these components for building tower cranes, masts or. Like. Have the major disadvantage that when the tower or mast is disassembled, the items are very bulky because the width of the dismantled tower or mast is equal to the width of one of its sides. This brings very big ones Difficulties with it, especially when towers or masts with a large cross-section are to be dismantled and loaded which the width of one side the regulatory norms for the Exceed road transport. In addition, the individual parts that make up the side panels have to be reassembled the shots are made, the disadvantage that they are not stable enough and very often damage during suffer during transport.
Die vorliegende Neuerung beseitigt diese Mängel. Sie besteht darin, daß der Turm oder Mast aus Winkelstücken geformt ist, die miteinander direkt oder indirekt verbunden sind, und zwar in der gleichen Anzahl wie die Seiten des Turmes oder Mastes, wobei jeder Flächenschenkel des Winkelstückes eine Breite hat, dieThe present innovation eliminates these shortcomings. It consists in the tower or mast being formed from elbows, which are directly or indirectly connected to one another, in the same number as the sides of the tower or mast, whereby each surface leg of the elbow has a width that
höchstens der Hälfte der Breite der jeweiligen Turmseite entspricht« corresponds to at most half the width of the respective tower side "
Durch diese Anordnung ist das Volumen des Turmes oder des Mastes in zusammengelegtem Zustand bedeutend verkleinert, da das Volumen in der Breite eines jeden Winkelstückes genau der Hälfte der Breite der jeweiligen Turmseiten entspricht. Es ist zu bemerken, daß wenn die Breite der so geschaffenen Elemente noch zu gross ist, es möglich ist, sie dadurch zu vermindern, daß man zwischen die jeweils durch die Verstrebungen gebildeten Halbflächen, die an den Aussenkanten miteinander verbunden werden sollen, eine Zwischenfläche anbringt, bestehend aus einem oder mehreren Gurten, Querträgern und Diagonalverstrebungen je nach Wunsch.With this arrangement, the volume of the tower or the Mast significantly reduced in size when folded, since the volume in the width of each angle piece is exactly that Half the width of the respective tower sides. It should be noted that if the width of the elements thus created is still too large, it is possible to reduce it by placing between the sections formed by the struts Half surfaces that are to be connected to one another at the outer edges, attach an intermediate surface, consisting of one or several belts, cross members and diagonal struts each as desired.
Die Neuerung wird mit Hilfe der folgenden Beschreibung unter Hinweis auf die beigefügte schematische Zeichnung, die als nicht einschränkendes Beispiel eine Ausführungsart eines so beschaffenen Kranturmes darstellt, verstanden. Es zeigen:The innovation is made with the help of the following description with reference to the attached schematic drawing, which as not restrictive example of an embodiment of one so designed Crane tower represents understood.

In der Figur 1 ist ein Kran dargestellt, von der Art, dessen Turm aus zwei Masten gebildet ist, wobei der innere sich nach oben hin verjüngt und den Ausleger trägt und in dem äusseren teleskopartig gleiten kann. Der äussere Mast ist in Form eines Käfigs gebaut. Durch das Übereinandersetzen ähnlicher Elemente kann er verlängert werden und besteht, wie etwas angedeutet, aus einzelnen Schüssen.In the figure 1 a crane is shown, of the type whose Tower is formed from two masts, the inner one tapers towards the top and carries the boom and the outer one can slide telescopically. The outer mast is built in the form of a cage. By placing similar elements on top of each other it can be lengthened and, as something indicated, consists of individual shots.
Die vorliegende Neuerung betrifft die Ausbildung der beiden Maste eines solchen Turmkranes, jedoch können andere Maste, die auch fachwerkartig gebaut sind, auf die gleiche Art und Weise hergestellt werden. Dabei besteht jeder Mast aus Elementen, die eine in sich widerstandsfähige Struktur aufweisen und die durch das Zusammenfügen von Winkelstücken gebildet werden.The present innovation relates to the design of the two masts of such a tower crane, but other masts can, too are built in the same way as trusses. Each mast consists of elements that have a have a robust structure in themselves and which are formed by joining angle pieces.
Wie in Figur 2 und 3 gezeigt, ist jedes Element, das in die Konstruktion der beiden Turmmaste eingefügt werden soll, aus Gurten 2 gebildet, die an ihnen befestigte Querträger 3 aufweisen und die Diagonalverstrebungen 4- haben, die jeweils die auskragenden Enden der Querverstrebungen 3 Jait dem Gurt 2 verbinden. Dadurch bilden sie jeweils kräfteauffangende Dreiecke. Diese Winkelstücke A, B, C und D sind miteinander verbunden, und zwar durch die Verbindung der Diagonalverstrebungen 4 und Querträger 3 in den Punkten a, b, c, d, e , f. Somit bilden die Winkelstücke A, B, C9 D jewils gemeinsam einen Käfig, der durch das Verbinden von vier derartigen Winkelstücken geformt wird und jeder von diesen Käfigen wird mit dem darauffolgenden oder darunterliegenden in den Punkten g, h, i, j verbunden. Ein solcherAs shown in Figures 2 and 3, each element to be inserted into the construction of the two tower masts is formed from straps 2 which have cross members 3 attached to them and which have diagonal struts 4 -, each of which has the cantilevered ends of the cross struts 3 Connect Jait to belt 2. As a result, they each form force-absorbing triangles. These angle pieces A, B, C and D are connected to one another, namely by connecting the diagonal struts 4 and cross members 3 at points a, b, c, d, e, f. Thus, the angle pieces A, B, C 9 D form each jointly a cage, which is formed by connecting four such angle pieces and each of these cages is connected to the following or below at points g, h, i, j. Such a
Käfig bildet einen sogenannten Schuss.The cage forms a so-called shot.
Es ist ersichtlich, daß die Anzahl und das Profil der Winkelstücke, die den Käfig formen, vom Querschnitt des aufzustellenden Mastes abhängt. Es ist also so, daß statt der Verwendung von vier derartiger Winkelstücke für die Herstellung eines Mastes mit rechteckigem Querschnitt man auch nur drei Winkelstücke zur Herstellung eines Mastes mit dreieckigem Querschnitt verwenden kann, wie es die Figur 4- zeigt. In diesem Fall bilden die Winkelstücke keinen rechten Winkel, sondern einen spitzen Winkel„It can be seen that the number and the profile of the elbows, that shape the cage, from the cross-section of the one to be erected Mastes depends. So it is so that instead of using four such angle pieces for the manufacture of a mast With a rectangular cross-section, you can only use three angle pieces to make a pole with a triangular cross-section can, as Figure 4- shows. In this case the angle pieces do not form a right angle, but an acute angle "
Die Gurte 2, die die Eckverbindungen der Winkelstücke bilden, werden vorteilhafterweise aus zwei Winkeleisen 2a und 2b gebildet, die durch Schweissen miteinander verbunden werden, um einen Kasten zu formen. Diese Winkeleisen 2a und 2b können von gleicher Stärke, aber auch von unterschiedlicher Stärke sein, um für den selben Turm als Gurt zur Herstellung der Winkelstücke zu dienen, insbesondere wenn es sich um einen Turm mit sich verjüngendem Querschnitt handelt, um ihm eine genügende Widerstandsfähigkeit gegen die Aufnahme von Lasten zu geben. Insbesondere bei Mastkonstruktionen spielt das eine Solle. Für das Aneinanderfügen von zwei übereinander angeordneten Gurten 2 besteht die Möglichkeit, ein Zwischenstück 5 einzusetzen und Ösen 6 anzuordnen, die die Verbindungsstelle verstärken und halten, wie es in Figur 5 und 6 dargestellt ist.The straps 2, which form the corner connections of the angle pieces, are advantageously formed from two angle irons 2a and 2b, which are joined together by welding to form a box. These angle irons 2a and 2b can be of the same Strength, but also of different strengths in order to use the same tower as a belt for making the contra-angle handpieces serve, especially if it is a tower with a tapered cross-section, to give it sufficient resistance to give against the taking of loads. This is particularly important for mast constructions. For joining of two straps 2 arranged one above the other, there is the possibility of inserting an intermediate piece 5 and arranging eyelets 6, which reinforce and hold the joint, as shown in FIGS.
Was die Diagonalverstrebungen 4 und Querträger 3 betrifft, die in Kombination mit dem Gurtes- 2 ein Winkelstück jeweils bilden,As for the diagonal struts 4 and cross members 3, the in combination with the belt 2 each form an angle piece,
so sind diese aus Profileisen hergestellt, die einerseits an dem Gurt 2 und andererseits auf Flanschen 7 verschweisst sind.they are made from profile iron which is welded on the one hand to the belt 2 and on the other hand to flanges 7.
Diese Flansche 7 werden entweder direkt miteinander verbunden durch beliebige Verbindungsmittel, beispielsweise Bolzen oder Mete oder unter Zwischenschaltung von Zwischenflächen 9a, wie es in Figur 6 strichpunktiert dargestellt ist, oder unter Zwischenschaltung von einem oder mehreren Gurten 9? wie es in Figur 5 strichpunktiert gezeigt ist. Auch können Zwischenteile mit losen Diagonalverstrebungen oder Querträgern eingesetzt werden.These flanges 7 are either connected directly to one another by any connecting means, for example bolts or Mete or with the interposition of intermediate surfaces 9a, such as it is shown in phantom in Figure 6, or with the interposition of one or more belts 9? like it in figure 5 is shown in phantom. Intermediate parts with loose diagonal struts or cross members can also be used will.
Durch die besondere Ausbildung der Winkelstück weist der Turm des Kranes bzw. auch der Kraninnenteil oder Mast den Vorteil auf, ein besonders geringes Volumen in demontiertem Zustand aufzuweisen. Die Winkelstücke haben tatsächlich nur eine Breite, die der Hälfte der Breite des Turmes oder des Mastes entspricht, ja, sogar geringer sein kann als die Hälfte der Breite, wenn Zwischenteile ^a. beispielsweise vorgesehen werden. Diese Winkelstücke können aufgestapelt und derart im Verhältnis zueinander angeordnet werden, wie es in den Figuren 8 bis 14 gezeigt ist, wobei mit 8 eine Leiter oder andere Teile des Kranes bezeichnet sind, die im Inneren des Raumes, den der Turm oder der Mast in zusammengelegtem Zustand bildet, untergebracht werden können.Due to the special design of the angle pieces, the tower of the crane or also the crane inner part or mast has the advantage of having a particularly small volume in the dismantled state. The angle pieces actually only have a width which corresponds to half the width of the tower or the mast, and can even be less than half the width if intermediate parts ^ a. for example be provided. These elbows can be stacked and arranged in relation to one another, as shown in FIGS State forms, can be accommodated.
Wie es selbstverständlich ist, beschränkt sich die Neuerung nicht nur auf die Ausführungsbeispiele, die beschrieben sind, sondern umfasst im Gegensatz dazu alle Ausführungsvarianten„As it goes without saying, the innovation is not limited to the exemplary embodiments that are described, but, in contrast, includes all design variants "
