Slotted Tabbed Rim Track and Building Method

Abstract

Adjustable slotted rim track for securing peripheral edges of a joist-floor panel assembly has a generally U-shaped planar web with interior depending tabs and opposite depending flanges normal to and separated by the web. The depending flanges may have a series of parallel adjustment slots for receiving fasteners through the flanges to connect and secure the rim track to a framing member such as a floor joist or floor panel assembly. Another design provides adjustment slots on the tabs instead of flanges. The slotted tabbed rim track design allows the joist-floor panel assembly to move relative to the rim track. Tabbed slots or angle clips affixed to the interior planar area of the rim track web are utilized for secure fastening of the adjustable rim track to the joist framing member during final installation of the assembly.

1 . An adjustable slotted tabbed rim track for securing peripheral edges of a joist and floor panel assembly comprising:
 a generally U-shaped planar web of steel track having a pair of depending side flanges normal to and separated by the web, where the depending flanges have a plurality of parallel adjustment slots for receiving fasteners through the flanges to thereby connect and secure the adjustable rim track to joist framing members of a floor panel assembly, the adjustment slots having elongated openings in the direction the flanges depend from the central web, thereby facilitating adjustment between the rim track and joist framing members; and   a plurality of tabs affixed to the interior of the planar area of the U-shaped rim track web and depending therefrom for securely fastening the rim track to a joist framing member in a floor panel assembly.   
   
   
       2 . The adjustable rim track of  claim 1  wherein the interior tabs are punched tabs integral to the web. 
   
   
       3 . The adjustable rim track of  claim 1  wherein the interior tabs are clip angles affixed to the interior of the web. 
   
   
       4 . The adjustable rim track of  claim 1  further comprising a framing member fastened to the rim track. 
   
   
       5 . The adjustable rim track of  claim 4  wherein the framing member is a flooring joist member. 
   
   
       6 . The adjustable rim track of  claim 5  further comprising a floor sheathing member. 
   
   
       7 . An adjustable slotted tabbed rim track for securing peripheral edges of a joist and floor panel assembly comprising:
 a generally U-shaped planar web of steel track having depending side flanges normal to and separated by the web; and   a plurality of tabs affixed to the interior of the planar area of the U-shaped rim track web and depending therefrom, the tabs having a plurality of parallel adjustment slots for receiving fasteners through the flanges to thereby connect and secure the adjustable rim track to joist framing members of a floor panel assembly, the tab slots having elongated openings in the direction the tabs depend from the central web, thereby facilitating adjustments between the rim track tabs and the framing members and for securely fastening the rim track to a joist framing member during final installation of the assembly.   
   
   
       8 . The adjustable rim track of  claim 7  wherein the interior tabs are punched tabs integral to the web. 
   
   
       9 . The adjustable rim track of  claim 7  wherein the interior tabs are clip angles affixed to the interior of the web. 
   
   
       10 . The adjustable rim track of  claim 7  further comprising a framing member fastened to the rim track. 
   
   
       11 . The adjustable rim track of  claim 10  wherein the framing member is a flooring joist member. 
   
   
       12 . The adjustable rim track of  claim 11  further comprising a floor sheathing member. 
   
   
       13 . A method of building construction comprising the steps of:
 affixing a joist framing member to an adjustable slotted tabbed rim track member where said rim track is a generally U-shaped planar web of steel track having a pair depending side flanges normal to and separated by the web; and a plurality of tabs affixed to the interior of the planar area of the U-shaped rim track web and depending therefrom, wherein at least one of the tabs or side flanges have a plurality of parallel adjustment slots for receiving fasteners therethrough to thereby connect and secure the adjustable rim track to a joist framing member of a floor panel assembly, the slots having elongated openings in a direction away from the central web;   adjusting the rim track and the framing members; and   fastening the rim track to the joist framing member.   
   
   
       14 . A method as in  claim 13  further comprising the step of affixing a floor sheathing member to provide a joist and floor panel assembly.
