AI Technical Summary

Technical Problem

Current steel construction systems face challenges such as complexity in component count, manufacturing time, and assembly due to the need for additional brackets and fasteners, which lead to increased costs, handling issues, and potential delays, as well as limitations in achieving specific geometries and material compatibility issues causing stress and loosening of connections.

Method used

A joint system for structural elements comprising a first beam with a cutout to accommodate a second beam, formed from overlapping sheet steel to create a closed hollow cross-section, with extending portions and corresponding holes for fasteners, providing moment and plane force resistance without the need for separate brackets.

Benefits of technology

This solution reduces the complexity of components, manufacturing time, and assembly, while enhancing force resistance and reducing costs by eliminating the need for additional brackets and improving material compatibility, thus streamlining the steel construction process.

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.
