         9 . The apparatus of  claim 8 , wherein the height of the support angle is adjustable without a vertical rod. 
     
     
         10 . A system for adjusting a haunch height, the system comprising:
 a support angle, the support angle comprising a horizontal portion and a vertical portion, wherein the vertical portion includes a plurality of holes spaced apart and positioned at different heights on the vertical portion, and wherein the horizontal portion is configured to support a deck form;   a rod or bar, wherein at least ends of the rod or bar are threaded;   a coupler, wherein the coupler includes an internal threading; and   a bolt, wherein the bolt is configured to extend through one of the plurality of holes in the support angle and into a portion of the coupler to adjust a height of the horizontal portion of the support angle and the deck form.   
     
     
         11 . The system of  claim 10 , wherein the support angle is a first support angle, and wherein the system further comprises a second support angle coupled to another coupler via another bolt, wherein the other coupler is coupled to another end of the rod or bar, and wherein the heights of the horizontal portions of the first and second support angles are variable based on the position of the rod or bar relative to the vertical portions of the first and second support angles. 
     
     
         12 . The system of  claim 10 , wherein the plurality of holes are arranged in a plurality of columns on the vertical portion of the support angle. 
     
     
         13 . The system of  claim 10 , wherein the plurality of holes are arranged diagonally on the vertical portion of the support angle. 
     
     
         14 . The system of  claim 13 , wherein the height of the support angle is adjustable by repositioning the bolt in another hole of the plurality of holes in the support angle. 
     
     
         15 . The system of  claim 14 , wherein the height of the support angle is adjustable without a vertical rod. 
     
     
         16 . The system of  claim 10 , wherein the system further comprises a clip angle, wherein the clip angle is coupled to another coupler via another bolt, wherein the other coupler is coupled to another end of the rod or bar. 
     
     
         17 . A system for adjusting a haunch height, the system comprising:
 a support angle, the support angle comprising a horizontal portion and a vertical portion, wherein the vertical portion includes a plurality of holes spaced apart and arranged diagonally different heights on the vertical portion, and wherein the horizontal portion is configured to support a deck form;   a rod or bar, wherein at least ends of the rod or bar are threaded;   a coupler, wherein the coupler includes an internal threading; and   a bolt, wherein the bolt is configured to extend through one of the plurality of holes in the support angle and into a portion of the coupler to adjust a height of the horizontal portion of the support angle and the deck form.
