ConX Chassis Based Modular building system
The ConX System reduces the structure of a building to a chassis of systemized components. The basis of the ConX chassis is the robust frame that is comprised of:
- HSS or box columns (in many cases concrete filled)
- Wide flange beams
- Three innovative patented connectors
- Two different moment frame/space frame connectors (ConXR and ConXL)
- A gravity connection
ConX technology enables premium performance structures to be rapidly and efficiently built without a cost premium. ConX beam and column assemblies are factory fabricated, and can be mass-customized or configured to meet a wide array of aesthetic design and structural loading criteria while remaining cost competitive in nearly any geography. ConX structures can be designed with moment connections at every primary beam-to-column intersection, resulting in a structurally rigid space frame. This innovative connection system enables beams to be simply lowered and locked onto square columns in the field, resulting in a dimensionally accurate structural chassis. The system is often referred to as a full-scale erector set.
Dimensional accuracy enables other factory built structural and architectural elements such as curtain wall systems, stairs, balconies, or other pre-fabricated sub-systems to be efficiently attached to the structural chassis.
As an example of the benefits of this systemized approach, a mid-rise building comprised of a ConX structural chassis, exit stairs, concrete filled corrugated metal deck, and exterior wall panels is constructed in vertical sections, enclosed, and ready for follow-on trades in weeks rather than months.
ConX system for different applications
The ConX System has two discrete variations that target different markets: ConXR™ and ConXL™
ConXR™ System
Average Bay Spacing: 15’ (range 8’ – 20’ feet)
Ideal Height Range: 4 – 12 stories (more dependent on geography)
Field Assembly Rate: 3,000 – 5,000 sf. / day including deck, exterior panels, exit stairs
Ideal For:
- Industrial – Pipe-rack, mining, refinery, processing structures
- High-density residential: military, condos, apartment, student, senior & assisted living, mixed-use
- Mid-to high-rise hotel
- Institutional facilities
- Small multi-story short span office structures
- Mid-rise urban storage
ConXL™ System
Average Bay Spacing: 30’ (range18’ – 65’)
Ideal Height Range: 2 -15 stories (higher with heavier box columns)
Field Assembly Rate: 10,000 sf. /day including deck, edge form, flashing
Ideal For:
- Industrial & petrochemical structures
- Hospital and healthcare facilities
- Data center
- R&D laboratories (excellent floor performance)
- GSA and DOS facilities, embassies
- Commercial office
- Educational and institutional facilities
- Military training facilities, barracks & other
- Low- to high-rise hotel & casino
- Multi-story retail
- High density residential & mixed-use
Streamlining the building process
Based on the theory that a finite number of precisely manufactured connectors, components and assemblies can be configured to achieve almost any design criteria, ConXtech employs Building Information Modeling (BIM) tools, robotics and CNC machining/ milling to streamline the building processes from structural design to manufacturing and field assembly.
