Description

KAISERLICHESIMPERIAL

PATENTAMT,PATENT OFFICE,

Den Gegenstand vorliegender Erfindung bildet ein Verfahren, um die in bekannter Weise durch Verschieben von Spannringen in neben- oder übereinanderliegenden Eiseneinlagen von Decken hervorgerufene Spannung zu sichern. Dies wird dadurch erreicht, daß jeder Spannring durch ein zwischen die Einlagen geklemmtes Metallstück festgelegt und so vor dem ZurückschnellenThe subject of the present invention forms a method to the known in Way by moving tension rings in iron inserts next to or on top of each other to secure tension caused by ceilings. This is achieved in that each clamping ring by an between the inlays clamped piece of metal set and so from snapping back

ίο gesichert wird.ίο is secured.

Dadurch sind die Eisen in der gewünschten Lage mit beliebiger Anfangsspannung festgelegt und vermögen die Zugspannungen in Massivdecken in der erreichbar vollkommensten Weise aufzunehmen.As a result, the irons are fixed in the desired position with any initial tension and the tensile stresses in solid ceilings are capable of being as perfect as possible Way to record.

Das der Erfindung zugrunde gelegte Verfahren ist auf der Zeichnung in einigen Ausführungsformen dargestellt und zwar in Fig. ι bei nebeneinander angeordneten Metalleinlagen und in den Fig. 2 und 3 bei übereinander angeordneten Eiseneinlagen, wobei d1 die Lage der Eisen vor und d2 nach der Anspannung zeigt.The basis of the invention defined process is shown in the drawing, in some embodiments, and although in Fig. Ι at juxtaposed metal deposits and in Figs. 2 and 3, superimposed iron deposits, where d 1 is the position of the iron before and d 2 according to the Shows tension.

Das Verfahren bedingt stets paarweise angeordnete Eiseneinlagen a, a, deren Enden in bekannter Weise an Trägern oder Mauern befestigt sind. Die vorher aufgeschobenen Ringe oder Klammern b werden in bekannter Weise so lange nach den Enden der Eisen verschoben, bis die gewünschte Anfangsspannung erreicht ist. In dieser Lage werden sie durch die zwischen die Eisen α eingelegten, das Zurückschnellen der Ringe oder Klammern b hindernden Metallstücke c, am besten Keile, festgelegt.The method always requires iron inlays a, a, arranged in pairs, the ends of which are fastened to girders or walls in a known manner. The previously pushed rings or brackets b are moved in a known manner after the ends of the iron until the desired initial tension is reached. In this position they are fixed by the metal pieces c, ideally wedges, placed between the iron α and preventing the rings or clamps b from snapping back.

Die nebeneinander angeordneten Metalleinlagen können, je nach der besonderen Ausführungsart der Massivdecke, entweder auf dem oberen oder aber auf dem untereren Trägerflantsche oder in dessen Höhenlage angebracht werden.The metal inserts arranged next to one another can, depending on the particular embodiment the solid ceiling, either on the upper or on the lower girder flange or at its height will.
