Bar-type supporting structure for forming a frame, comprising a plurality of nodes and bars connecting the nodes

Abstract

The invention relates to a bar-type supporting structure for forming a frame, comprising a plurality of nodes and bars connecting the nodes, wherein each bar comprises at least one recess extending in the longitudinal direction of the bar, wherein the respective recess continues right into the node.

1 . A bar-type supporting structure for forming a frame comprising:
 a plurality of nodes;   at least one bar connecting said nodes, each bar comprising at least one flute extending in the longitudinal direction of said bar, a respective one of said flutes extending into said node.   
     
     
         2 . A bar-type supporting structure as set forth in  claim 1 , wherein at least one of the nodes comprises at least two socket elements to receive one bar each. 
     
     
         3 . A bar-type supporting structure as set forth in  claim 2 , wherein the socket element of the node comprises a recess, the bar comprising at its end a shoe conforming to the shape of said recess, said shoe being connectable with said socket element in the region of said recess 
     
     
         4 . A bar-type supporting structure as set forth in  claim 3 , wherein the shoe is connectable with said socket element by a material-to-material bond. 
     
     
         5 . A bar-type supporting structure as set forth in  claim 4 , wherein the material-to-material bond is glue. 
     
     
         6 . A bar-type supporting structure as set forth in  claim 2 , wherein the recess is configured in the fashion of a scalene trapezoid in cross section. 
     
     
         7 . A bar-type supporting structure as set forth in  claim 1 , wherein the bar comprises two flutes extending parallel to each other, and a central flute line extending between said two flutes. 
     
     
         8 . A bar-type supporting structure as set forth in  claim 1 , wherein the flute results in a flute line which is of lesser height than the side flank of the bar. 
     
     
         9 . A bar-type supporting structure as set forth in  claim 8 , wherein the height of the flute line is approximately two-thirds the height of the side flank of the bar. 
     
     
         10 . A bar-type supporting structure as set forth in  claim 1 , wherein the flutes are substnatially identical in size. 
     
     
         11 . A bar-type supporting structure as set forth in  claim 1 , wherein the bar-type supporting structure is configured to be cuboid. 
     
     
         12 . A bar-type supporting structure as set forth in  claim 11 , wherein the frame is filled with a fill material inside the cuboid bar-type supporting structure. 
     
     
         13 . A bar-type supporting structure as set forth in  claim 12 , wherein the fill material is different from the material of said bar-type supporting structure. 
     
     
         14 . A bar-type supporting structure as set forth in  claim 12 , wherein the fill material is at least one of a heat insulating, a sound insulating, or a heat storing material. 
     
     
         15 . A bar-type supporting structure as set forth in  claim 12 , wherein at least one side of the cuboid bar-type supporting structure comprises at least one of a vapor retarder, a vapor barrier, or a foil adapting to humidity. 
     
     
         16 . A bar-type supporting structure as set forth in  claim 11 , further comprising a plurality of bar portions, which extend parallel to each other and comprise a disconnection point, wherein the bar portions are joined together at said disconnection point by an intermediate member. 
     
     
         17 . A bar-type supporting structure as set forth in  claim 16 , wherein the intermediate member exhibits low heat conducting properties. 
     
     
         18 . A bar-type supporting structure as set forth in  claim 1 , wherein the cuboid bar-type supporting structure receives a hollow body in an elastic resilient manner in all the three directions in space. 
     
     
         19 . A bar-type supporting structure as set forth in  claim 18 , wherein the cuboid bar-type supporting structure comprises a spring/damper system from which the hollow body is suspended. 
     
     
         20 . A bar-type supporting structure as set forth in  claim 19 , wherein the spring/damper system is disposed in the center of the node. 
     
     
         21 . A bar-type supporting structure as set forth in  claim 19 , wherein the bar-type supporting structure comprises receiving elements for receiving the spring/damper system. 
     
     
         22 . A bar-type supporting structure as set forth in  claim 21 , wherein the receiving elements are disposed in the region of the central flute line. 
     
     
         23 . A bar-type supporting structure as set forth in  claim 19 , wherein the spring/damper system is adjustable in its damping characteristics. 
     
     
         24 . The bar-type supporting structure as set forth in  claim 1 , wherein both the bars and the nodes are made from concrete.
