Stud assembly

Abstract

An implementation of a stud assembly disclosed herein includes an external stud and an internal stud inserted longitudinally into the external stud, wherein the internal stud has cross-sectional dimensions that are smaller than the cross-sectional dimensions of the external stud. Each of the internal stud and the external stud may include a web, two flanges connected to the web, and two lips connected to the two flanges. Furthermore, each of the internal stud and the external stud may be created from a cold-rolled steel.

         2 . The stud assembly of  claim 1 , wherein each of the external stud and the internal stud includes a web, two flanges, and two lips. 
     
     
         3 . The stud assembly of  claim 2 , wherein the cross-sectional width of the web of the internal stud is smaller than the cross-sectional width of the web of the external stud. 
     
     
         4 . The stud assembly of  claim 2 , wherein the cross-sectional heights of the flanges of the internal stud are smaller than the cross-sectional heights of the flanges of the external stud. 
     
     
         5 . The stud assembly of  claim 2 , wherein the internal stud is created by shrinking another external stud using a roll-forming machine. 
     
     
         6 . The stud assembly of  claim 2 , wherein the web of the external stud comprises an indentation substantially near the center of the external stud and towards the lips of the external stud. 
     
     
         7 . The stud assembly of  claim 6 , wherein the indentation is in the shape of an arc. 
     
     
         8 . The stud assembly of  claim 2 , wherein the web of the internal stud comprises an indentation substantially near the center of the internal stud and towards the lips of the internal stud. 
     
     
         9 . The stud assembly of  claim 8 , wherein the indentation is in the shape of an arc. 
     
     
         10 . The stud assembly of  claim 2 , wherein the lips of the internal stud are curved such that the ends of the lips away from the flanges of the internal stud are closer to the web of the internal stud than the ends of the lips closer to the flanges of the internal stud. 
     
     
         11 . The stud assembly of  claim 2 , wherein the flanges of the internal stud are curved such that the ends of the flanges closer to the lips of the internal stud are closer to each other compared to the ends of the flanges closer to the web of the internal stud. 
     
     
         12 . The stud assembly of  claim 2  further comprising support mechanisms attached to the internal surfaces of each of the flanges of the external stud. 
     
     
         13 . A device comprising:
 an external stud comprising an external stud web, two external stud flanges attached to each of two web ends of the two external stud flanges, and two external stud lips attached to each of two lip ends of the external stud flanges; and   an internal stud comprising an internal stud web, two internal stud flanges attached to each of two web ends of the two internal stud flanges, and two internal stud lips attached to each of two lip ends of the internal stud flanges,   wherein the width of the external stud web is larger than the width of the internal stud web and the height of the external stud flanges is larger than the height of the internal stud flanges.   
     
     
         14 . The device of  claim 13 , wherein the internal stud is positioned inside the external stud. 
     
     
         15 . The device of  claim 14 , wherein the internal stud is positioned inside the external stud such that the internal stud lips are in proximity of the external stud web and the internal stud web is in proximity of to the external stud lips. 
     
     
         16 . The device of  claim 14 , wherein each of the external stud and the internal stud are created from cold rolled steel using a roll-forming machine. 
     
     
         17 . The device of  claim 14 , wherein the external stud further comprising support mechanisms attached to inside surfaces of each of the external stud flanges. 
     
     
         18 . A method, comprising:
 forming an external stud comprising an external stud web, two external stud flanges attached to each of two web ends of the two external stud flanges, and two external stud lips attached to each of two lip ends of the external stud flanges;   forming an internal stud comprising an internal stud web, two internal stud flanges attached to each of two web ends of the two internal stud flanges, and two internal stud lips attached to each of two lip ends of the internal stud flanges;   shrinking the internal stud such that cross-sectional dimensions of the internal stud along the length of the internal stud are smaller than cross-sectional dimensions of the external stud; and   inserting the internal stud into the external stud longitudinally.   
     
     
         19 . The method of  claim 18 , wherein forming an external stud further comprising forming an external stud from cold-rolled steel. 
     
     
         20 . The method of  claim 18 , wherein inserting the internal stud into the external stud further comprising inserting the internal stud into the external stud such that at least two or more of the external side surfaces of the internal stud are in contact with the internal side surfaces of the external stud.
