ConX® Systems

Chassis Based Modular®:

A concept developed by ConXtech where a mass-customizable structural steel chassis made up of standard connections is used to organize and support other modular systems or assemblies. This not only applies in the built environment, but also in the digital environment during design, using standardized modular connections and interfaces – creating a “System of Systems” which enables simple integration of other modular parts. The primary components to the ConX System are:

  • ConX beam and column assemblies: Steel beams and columns to which ConX connectors are factory welded resulting in dimensionally accurate structural framing components
  • ConX Collar: Our matching sets of ConX connectors simply and safely lower & lock together in the field forming a robust bi-axial moment “collar” around a column

Three ConX Systems, Many Types of Structures

All ConXtech structures are designed with tapered, “lower & locking” steel connections that enable safe and rapid assembly. Each ConX System has a standard connection, column size and range of beam spans that form a kit of parts for a certain size structure. If you’re designing a high-density residential or hospitality structure, the ConXR 200 System is most likely the right size. Our largest system, ConXL 400, is scaled appropriately for most healthcare, data center and commercial structures. Below are the three ConX Systems and their general parameters. Each is a standalone system used throughout the primary frame and supplemented with ConX Gravity Connections.

* Allowable beam depth can be greater than or less than this range, dependent upon structural performance criteria.
** Allowable spans may vary from those shown above, dependent on beam tributary area and floor loading.

ConX® Gravity Connections

ConX Gravity Connections are lower & locking, bolted connections used for secondary and joist beams, and can be incorporated into all three ConX Systems.

Based on a plasma-cut hook in the beam and a pre-installed bolt in the mating connection (on beam or column), ConX Gravity Connections have the same self-aligning, gravity-stabilized features of ConXtech’s moment connections — enabling fast, safe assembly without field welding.
