Abstract

The present invention provides a modular end shoe for a cold-rolled sheet steel joist having a Z-shaped shear connector top chord or a C or Z-shape in non-composite construction, comprising a bearing surface for bearing on a support for the joint end, and means for connecting the bearing surface to the web and top chord of the joist and fastening means connecting the modular end shoe to the top chord and to the web.

I claim:  
     
         1 . A modular end shoe for attachment to a sheet steel joist having a Z-shaped top chord and a vertical web comprising: 
 a bearing surface for transmitting load to a support,    means for connecting said bearing surface to the web and top chord of the joist, including fastening means joining said connecting means to said top chord and web.    
     
     
         2 . An end shoe as defined in  claim 1 , wherein said means for connecting said bearing surface to the top chord and web of said joint comprises an L-shaped vertical member adapted to be positioned adjacent and fastened to the web, and extending over and connected to the bearing surface.  
     
     
         3 . An end shoe as defined in  claim 2 , wherein said bearing surface is formed by a back strap and extending over said L-shaped member and said top chord and fastened thereto, and said fastening means includes means for fastening said portion of said back strap extending over said top chord to said top chord.  
     
     
         4 . An end shoe as claimed in  claim 2 , including a clamping plate attached to the back strap and parallel and spaced from said L-shaped member, and positioned to permit the web of said joist to be positioned between the L-shaped member and the clamping plate, and fastening means extending through said clamping plate, said web and said L-shaped member.  
     
     
         5 . An end shoe as in  claim 4  wherein said fastening means is a plurality of self drilling, self-tapping screws.  
     
     
         6 . A sheet steel joist having a modular end shoe as defined in  claim 1  on each end thereof.
