         10 . A prefabricated framing member support system for use with a horizontal framing member, the horizontal framing member comprising a top chord, a bottom chord, and a web connecting the top chord to the bottom chord, the prefabricated support system comprising:
 an integrated rim board component comprising:
 a substantially vertical portion having a top end and a bottom end; and 
 a substantially horizontal portion attached to the bottom end of the substantially vertical portion with an assembly component thereby forming an L-shape; 
   wherein the integrated rim board component is configured to support the horizontal framing member when the horizontal framing member is placed on the substantially horizontal portion so that:
 the web is arranged in a first plane that is perpendicular to the substantially vertical portion; 
 the top chord and the bottom chord are arranged in a second plane, the second plane being substantially parallel to the substantially horizontal portion and substantially perpendicular to the first plane and the substantially vertical portion; 
 the bottom chord makes contact with the substantially horizontal portion and the substantially vertical portion; 
 the top chord makes contact with the substantially vertical portion; and 
 the web makes contact with the substantially vertical portion; 
   wherein the substantially horizontal portion is connected to the substantially vertical portion before the horizontal framing member is placed on the substantially horizontal portion;   wherein the assembly component is a mechanical fasteners or a chemical fastener before being configured to support the horizontal framing member.
