Abstract

A joint system for structural elements for a building construction, comprising a first beam formed from at least two pieces of overlapping sheet steel to define a closed hollow cross-section, a second beam having a hollow cross-section, the first beam having at least two unitarily formed opposing extending portions having a distance between them to accommodate, when in a jointed condition, the second beam therebetween, the extending portions and the second beam each having a plurality of corresponding, when in a jointed condition, spaced apart holes to receive fasteners therethrough, such that when in a jointed and fastened condition the joint system provides a joint system that is moment, in plane, and out of plane, force resistant and wherein the extending portions are formed from at least one of the at least two pieces of overlapping sheet steel that define the closed hollow cross-section beam.

         8 . A joint system of  claim 7  wherein the two opposing extending portions each present planar inward facing surfaces that in part define a complimentary pocket. 
     
     
         9 . A joint system of any one of  claims 1 to 8  wherein a substantial length of the first and/or second beam have an enclosed cross-sectional. 
     
     
         10 . A joint system of any one of  claims 1 to 9  wherein the first and second beams are of constant cross-sectional along their length. 
     
     
         11 . A joint system of any one of  claims 1 to 10  wherein the closed hollow cross-sectional beam is of rectangular or square cross-sectional. 
     
     
         12 . A joint system of any one of  claims 1 to 11  wherein at least one of the extending portions includes at least one reinforcing rib formed onto the exterior surface of the extending portion. 
     
     
         13 . A joint system of  claim 12  wherein the one or more reinforcing ribs run parallel to the main axis of the first beam. 
     
     
         14 . A joint system of  claim 12 or 13  wherein the reinforcing ribs extend from the extending portions into the body of the first beam. 
     
     
         15 . A joint system of any one of  claims 1 to 14  wherein the second beam has threaded connections complimentary to the spaced apart holes, inward of an external surface of the second beam, to receive and engage fasteners therein. 
     
     
         16 . A joint system of any one of  claims 1 to 15  wherein the sheet steel thickness is between 2 to 10 mm thick. 
     
     
         17 . A joint system of any one of  claims 1 to 16  wherein the closed hollow cross-section beam(s) are formed from first and second open cross-sectional beams that are nested, one inside the other. 
     
     
         18 . A joint system of any one of  claims 1 to 17  wherein the closed hollow cross-section beams have two opposed vertical webs, and two opposed horizontal flanges connecting therebetween.
