Description

lenkung hindurch in die Unterlage, z. B. dar, Fundament, einen Pfeiler od. dgl., geleitet.steering through into the base, z. B. dar, foundation, a pillar or the like., directed.

Dank des Fotmschlusses zwischen den Scheiben 5 und den sie aufnehmenden Bohrungen 7 können zwischen den aufeinanderlegenden Trägern des Stapels große waagerechte Kräfte übertragen werden.Thanks to the photo connection between the panes 5 and the holes 7 receiving them can be between the superposed supports of the stack large horizontal forces are transmitted.

Der Stapel wird oben durch eine Platte 8 abgeschlossen Diese bildet ein Quadrat, dessen Seite gleich der Länge eines Trägers ist. Ihre Dicke ist mindestens gleich der Dicke der Scheiben 5. Sie hat Bohrungen 9, deren Durchmesser gleich dem Durchmesser der Bohrungen 7 ist. Die Bohrungen 9 sind so angeordnet, daß ihre Mittenabstände gleich α sind und die Platte 8, wenn die Scheiben 5 der obersten Träger passend in die Bohrungen 9 eingreifen, ringsum mit dem Grundriß des Stapels abschließt. Durch das Auflegen der Platte 8 auf die obersten Träger des Stapels wird eine glätte Auflagerfläche für die Baukonstruktion od. dgl. geschaffen.The stack is closed at the top by a plate 8, which forms a square, the side of which is equal to the length of a carrier. Its thickness is at least equal to the thickness of the disks 5. It has bores 9, the diameter of which is equal to the diameter of the bores 7. The bores 9 are arranged so that their center distances are equal to α and the plate 8, when the disks 5 of the uppermost carrier fit into the bores 9, flush all around with the plan of the stack. By placing the plate 8 on the topmost carrier of the stack, a smooth support surface for the building structure or the like is created.

Derartige Stapel werden vorzugsweise beim Freivorbau von Brücken verwendet: Hierbei wird der Brückenträger auf den Pfeilern und Hilfsstützen durch untergebaute Stapel zunächst überhöht angelegt, damit seine Durchbiegung bis zum Erreichen des nächsten Pfeilers oder der nächsten Hilfsstütze ausgeglichen wird. Doch sind Stapel nach der Erfindung auch in anderen Fällen anzuwenden, wo Lastkörper vor dem endgültigen Absetzen in dei vorgeschriebenen Höhe zunächst in einer Zwischenstufe der Montage aufgelegt werden müssen, wobei es sich z. B. um Betonfertigteile, Stahlkonstruktionen oder Maschinen leder Art handeln kann.Such stacks are preferably used in the cantilever construction of bridges: Here the Bridge girders on the pillars and auxiliary supports initially raised by piles built underneath, so that its deflection is compensated for until it reaches the next pillar or the next auxiliary support will. However, stacks according to the invention can also be used in other cases where load bodies before final weaning in the prescribed Height must first be placed in an intermediate stage of the assembly, it being z. B. to Precast concrete, steel structures or machinery can act as leather type.
