Improvements in, or relating to, a joint and system therefor

A method of forming 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, and
• locating the second beam between the at least two unitarily formed opposing extending portions, and locating fasteners through the first plurality of spaced apart holes, and second plurality of spaced apart holes 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.

A kit of parts for forming a joint between a second beam and a first beam, 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 second beam having a second plurality of spaced apart holes on opposing sides thereof to receive the same fasteners therethrough, complimentary to the first plurality,
• a plurality of fasteners to engage between the first plurality of spaced apart holes and their corresponding second plurality of spaced apart holes,
• such the first and second beam may be fastened together using the fasteners to form a jointed beam that is moment, in plane, and out of plane, force resistant.
