Structural beam

Abstract

A structural beam having a plurality of tabs integrally formed with the sidewall of the beam. The tabs are formed from punched-out sections of the sidewall by a rolling guide with a punch that pierces a portion of the sidewall in order to forcibly bend the section outward to define the tab. Each of the respective tabs in the plurality are substantially curved in side elevational view and closely represented by a half U-shaped tab. One end of the tab is integrally formed with the sidewall by a bend or fold joint while the other end is cantilevered outwardly in a lateral direction from the sidewall and is substantially curved in a direction over the opening or hole caused by the punch procedure. The distal end of the tab resides midway across the opening. The tabs are formed on structural beams which may be arranged vertically or horizontally on a building structure or construction.

1 . A structural beam comprising: 
 a structural beam having a sidewall of a given thickness;    a punched cut-out in said sidewall constituting a tab cantilevered laterally with respect to said sidewall;    said tab having a first portion integral with said sidewall and connected therewith by a bent joint;    said tab having a second portion extending perpendicular with respect to said first portion in fixed, spaced-apart relationship to said sidewall; and    a curved portion integrally connecting said first portion with said second portion.    
   
   
       2 . The structural beam defined in  claim 1  wherein: 
 said sidewall is provided with a punch-out opening defined by said punched cut-out and said second portion having a distal end terminating midway between opposite ends of said opening.    
   
   
       3 . The structural beam defined in  claim 2  wherein: 
 said first portion and said second portion are linear.    
   
   
       4 . The structural beam defined in  claim 3  wherein: 
 said tab defines a space between an underside of said second portion and said sidewall which is open and in communication with said opening.    
   
   
       5 . The structural beam defined in  claim 4  wherein: 
 said opening conducting a filling substance about said tab and for occupying said space.    
   
   
       6 . The structural beam defined in  claim 5  wherein: 
 said tab is of an area equal to the area defining said opening.    
   
   
       7 . The structural beam defined in  claim 6  wherein: 
 said tab having a width and a length equal to a width and length of said opening.
