Description
Die bekannten Leitergerüste werden aus Holzleitern gebildet. Abgesehen davon, daß die Beschaffung von Holzleitern jetzt auf Schwierigkeiten stößt, ist die Erstellung von Gerüsten, deren Höhe die Länge der Einzelleitern übersteigt, recht umständlich und zeitraubend. Am Verlängerungsstoß überdecken sich die Leitern, wodurch die wirksame Leiterlänge verkürzt wird.The known ladder scaffolds are formed from wooden ladders. Apart from that of the fact that the procurement of wooden ladders is now encountering difficulties the creation of scaffolding, the height of which exceeds the length of the individual ladders, quite cumbersome and time consuming. The ladders overlap at the extension joint, whereby the effective length of the ladder is shortened.
Zur Vermeidung dieser Mißstände wird erfindungsgemäß vorgeschlagen, die Leitern aus Stahlrohren zu fertigen, wobei beide Enden jeder Leiter mit aus Flacheisen gefertigten Sprossen ausgestattet sind. Bei der Erstellung höherer Gerüste werden die Einzelleitern mit ihren Endsprossen aufeinandergestellt. Die Endsprossen sind mit vorzugsweise zwei Bohrungen versehen, die zur Aufnahme von Verbindungsschrauben dienen. Die aus Rohren gefertigten Sprossen sind durch die gleichfalls aus Rohren bestehenden Holme hindurchgeführt und an beiden Enden offen, während die Enden der Holmrohre zweckmäßig geschlossen sind.To avoid these shortcomings, it is proposed according to the invention, Manufacture the ladders from steel tubing, with both ends of each ladder made from Flat iron made rungs are equipped. When creating higher scaffolding the individual ladders are placed on top of one another with their end rungs. The end rungs are preferably provided with two bores for receiving connecting screws to serve. The rungs made from pipes are also made from pipes existing spars passed through and open at both ends, while the ends of the Spar tubes are expediently closed.
Abb. i zeigt einen Teil eines Leitergerüstes nach der Erfindung in schaubildlicher Darstellung, und Abb. 2 und 3 stellen Ansicht und Grundriß eines Leiterendes dar. Die Leitern i sind durch Diagonalstreben 2 verbunden, wobei die Befestigung mittels Bolzen erfolgt, die durch die Leitersprossen hindurchgesteckt sind. Beide Enden jeder Leiter tragen eine aus Flacheisen gefertigte Endsprosse 3, sie ist mit Löchern 4 versehen, die zur Aufnahme von Schraubenbolzen dienen, welche die kraftschlüssige Verbindung von übereinanderstehenden Leitern herbeiführen.Fig. I shows part of a ladder frame according to the invention in diagrammatic representation, and Figs. 2 and 3 represent a view and plan view of one Ladder end. The ladders i are connected by diagonal struts 2, the It is fastened by means of bolts that are pushed through the ladder rungs are. Both ends of each ladder carry an end rung made of flat iron 3, it is provided with holes 4, which are used to accommodate screw bolts, which bring about the frictional connection of ladders standing on top of one another.
Die Errichtung von Leitergerüsten nach der Erfindung läßt sich wegen der besonders einfachen Verbindung wesentlich schneller als bei Holzleitergerüsten durchführen. Durch die Anordnung der Endsprossen, die das Verbindungselement darstellen, wird jede Gefahr einer Verbiegung der Holmenden ausgeschlossen.The establishment of ladder scaffolding according to the invention can be because of the particularly simple connection much faster than with wooden ladder scaffolding carry out. Due to the arrangement of the end rungs, which represent the connecting element, any risk of bending the spar ends is excluded.
