Beam member of concrete forming apparatus having a supported nail strip

Abstract

A metal secondary beam used to support sheathing in concrete forming apparatus has a support structure for a nailer that is substantially open to allow concrete bleed water, to readily drain away thereby preventing deterioration of the nailer due to extended contact of water with the nailer. In a preferred embodiment, the support structure is a series of bent tabs lanced in the beam member.

1 . A metal beam member for use in concrete forming systems, comprising: 
 (a) a pair of longitudinal side members forming a channel and a top surface;    (b) a nailer received in the channel; and    (c) an open support structure formed in the side members for supporting the nailer flush with the top surface.    
   
   
       2 . A beam member as defined in  claim 1 , wherein in the open support structure is comprised of a plurality of tabs that extend into the channel.  
   
   
       3 . A beam member as defined in  claim 2 , wherein the tabs are arranged in a row spaced below the top surface.  
   
   
       4 . A beam member as defined in  claim 1 , wherein the pair of side members are arranged back-to-back in a spaced relation.  
   
   
       5 . A beam member as defined in  claim 4 , further comprising a pair of end plates secured at opposite ends of the longitudinal side members.  
   
   
       6 . A metal beam member for use in concrete forming systems, comprising: 
 (a) a pair of longitudinal side members arranged back-to-back and spaced apart to form a channel;    (b) flanges of the side members that form a top support surface;    (c) a plurality of tabs formed in each of the side members and extended into the channel and arranged in a row spaced below the top support surface; and    (d) a nailer received in the channel and supported on the tabs with an exposed face flush with the top support surface.
