Description

Z-förmiger, nachgiebiger Kappschuh mit Quetscheinlage Die bekannten Z-förmigen, nachgiebigen Türstockverbindungen mit Quetscheinlage sind meist so konstruiert, daß die einzelnen Teile (Eisenteile und Quetschmass,.) nicht zusammenhängend verbunden sind, also auseinanderfallen können. Die Quetschmasse wird läufig nur von zwei Seiten von der Eisenarmienmg umschlossen, kann also herausfallen oder dem Druck ausweichen. Alle diese Türstockverbindungen sind gewöhnlich entweder nur in senkrechter Richtung, .also gegen Druck von oben nach unten nachgiebig oder nur bei eintretendem Seitendruck.Z-shaped, yielding cap shoe with squeeze insert The well-known Z-shaped, flexible door frame connections with squeeze insert are usually designed in such a way that that the individual parts (iron parts and squeezed dimensions) are not connected are, so can fall apart. The squeeze mass is flowing only from two sides enclosed by the iron armament, so it can fall out or evade the pressure. All these door frame connections are usually either only in the vertical direction, . So yielding against pressure from top to bottom or only when there is pressure from the side.

Diese Mängel sind durch die der Erfindung zugrunde liegende Erfindung behoben.These shortcomings are due to the invention on which the invention is based Fixed.

Die Türstockverbindung der Erfindung besteht aus Flacheisen, das in die in der beiliegenden Zeichnung dargestellte Z-Hohlform gepreßt ist und dessen Enden zusammengeschweißt sind, so daß eine in sich geschlossene Form entsteht, in welche die Quetschmasse, Holz o. dgl., eingeschoben ist. Die Quetschmasse ist also allseitig von der Eisenarmierung umschlossen. Bei eintretendem Druck von oben wird die Quetschmasse in senkrechter Richtung beansprucht. Durch Seitendruck wird die Armierungsform seitlich verschoben und die Quetschmasse in den beiden Seitennasen belastet. Die Türstockverbindung ist also in senkrechter und waagerechter Richtung nachgiebig.The door frame connection of the invention consists of flat iron that is in the Z-shaped mold shown in the accompanying drawing is pressed and its Ends are welded together so that a self-contained shape is created in which the crushed mass, wood or the like. Is inserted. So the squeezed mass is Enclosed on all sides by the iron reinforcement. When pressure is applied from above the crushed mass is stressed in the vertical direction. By printing on the side, the Reinforcement shape shifted sideways and the squeezed mass in the two side lugs burdened. The door frame connection is therefore in the vertical and horizontal direction yielding.
