A Design Study in Steel - Cast Connex Steel Construction Connector

Bolt Holes
One of the advantages of casting is that detailed features can be produced in a near-net shape configuration in the casting process.  This capability can reduce or even eliminate expensive machining steps. 

  • One of the design choices for the connector is whether and how to produce the bolt holes in the connector plates.

  • Bolt holes can be rough and finish drilled into the finished casting

  • Or they can be produced in the castings with features on  the sand core and then finish drilled  after casting.  

 

  • The deciding factor was the fact that there are no standard bolt hole configurations for these structural connectors.  

  • In actual use each structural designer chooses the bolt size, count, and configuration based on the structural loads he has to work with.

  • With that in mind, it was decided to produce the connector without bolt holes and let the field engineers drill  the holes they need for their design.
