Shear connector using perforated and/or cut out plate

Abstract

The present invention relates to a shear connector having perforated and/or cut-out plates. In a T-shaped steel plate having a certain length, there are provided a plurality of through holes at a flange and a web. The flanges may be cut-out in biased method, and a plurality of through holes may be formed at the web. In the present invention, it is possible to achieve a perfect combination or a partial combination effect between a steel material and concrete. In addition, it is possible to enhance a weight resistance ability and a resistance ability with respect to transformation in such a manner that weight transfer function is provided between different materials.

1 . A shear connector having a predetermined length in a T-shaped steel plate, comprising: 
 a flange and a web having a plurality of through holes.    
   
   
       2 . The connector of  claim 1 , wherein said web has a plurality of valley portions and ridges in wave shapes.  
   
   
       3 . The connector of  claim 1 , wherein a plurality of protrusions and/or grooves are formed at the flange and the web.  
   
   
       4 . The connector of  claim 3 , wherein said web has a plurality of valley portions and ridges in wave shapes.  
   
   
       5 . A shear connector having a predetermined length in a T-shaped steel plate, comprising: 
 a flange formed of a plurality of flange pieces wherein said flange pieces are cut-out in biased shapes; and    a web having a plurality of through holes.    
   
   
       6 . The connector of  claim 5 , wherein said web has a plurality of valley portions and ridges in wave shapes.  
   
   
       7 . The connector of  claim 5 , wherein a plurality of protrusions and/or grooves are formed at the flange and the web, respectively.  
   
   
       8 . The connector of  claim 7 , wherein said web has a plurality of valley portions and ridges in wave shapes.  
   
   
       9 . A shear connector having a predetermined length in a Z-shaped steel plate, comprising: 
 an upper flange and a web having a plurality of through holes.    
   
   
       10 . The connector of  claim 9 , wherein said web has a plurality of valley portions and ridges in wave shapes.  
   
   
       11 . The connector of  claim 9 , wherein a plurality of protrusions and/or grooves are formed at the flange and the web, respectively.  
   
   
       12 . The connector of  claim 11 , wherein said web has a plurality of valley portions and ridges in wave shapes.
