Pillar with load-branching nodes and adjustable run-out angle

Abstract

The present invention relates to a free pillar having a shaft, a load-branching node provided at the upper end of the shaft and at least two cantilever arms which are each connected at one end to the load-branching node and at the other end support the superstructure, and is characterized in that the load-bearing node includes a dome surface and a number of cantilever arm connections which corresponds to the number of cantilever arms, and in that the cantilever arm connections are arranged in such a manner that the center axes of the cantilever arm connections and of the shaft meet at a common point of intersection.

1 . A free pillar having a shaft, a load-branching node provided at the upper end of the shaft and at least two cantilever arms which are each connected at one end to the load-branching node and at the other end support the superstructure,
 wherein the load-branching node includes a dome surface and a number of cantilever arm connections which corresponds to the number of cantilever arms, and in that the cantilever arm connections are arranged in such a manner that the center axes of the cantilever arm connections and of the shaft meet at a common point of intersection.   
     
     
         2 . The pillar as claimed in  claim 1 , wherein the dome surface comprises a form which is at least symmetrical to a plane of symmetry running through the center axis of the shaft or rotationally symmetrical to the center axis of the shaft. 
     
     
         3 . The pillar as claimed in  claim 2  wherein, the dome surface is realized substantially in the form of a spherical segment, and in that the cantilever arm connections are connected to the dome surface via circular surfaces, as a result of which the common point of intersection of the center axes lies in the center of the spherical segment. 
     
     
         4 . The pillar as claimed in  claim 3 , wherein the cantilever arms are connected to the cantilever arm connections by means of screw flanges. 
     
     
         5 . The pillar as claimed in  claim 3 , wherein the cantilever arm connections are realized in one piece with the cantilever arms. 
     
     
         6 . The pillar as claimed in  claim 5 , wherein the load-branching node includes a transition, wherein the dome surface is connected to the shaft by means of the transition, and wherein the transition compensates for at least one of different diameters and cross-sectional forms of the shaft and of the dome surface. 
     
     
         7 . The pillar as claimed in  claim 6 , wherein the transition comprises at least one of a continually changing diameter and cross section. 
     
     
         8 . The pillar as claimed in  claim 7  wherein the parts of the load-branching node are welded together. 
     
     
         9 . The pillar as claimed in  claim 8  wherein bulkhead plates are provided in the load-branching node. 
     
     
         10 . The pillar as claimed in  claim 9  wherein the cantilever arms are realized as tubing with one of a constant and conical cross section. 
     
     
         11 . The pillar as claimed in  claim 10 , wherein the cantilever arms are one of curved and molded in 3D. 
     
     
         12 . The pillar as claimed in  claim 11  wherein the shaft is realized as a spirally welded tube.
