ABSTRACT:
Disclosed herein is a stock bar and T-bar coupling structure for mounting a sprinkler. In the present invention, a locking bracket is easily securely coupled to a T-bar using an elastic locking unit and a wing bolt. Furthermore, a stock bar made of standard rectangular pipe is coupled to the locking bracket by a first locking unit such that the stock bar crosses over the T-bar. Because this locking bracket is manufactured as a separate component from the stock bar, the present invention can be used without limiting the distance between the T-bars. Furthermore, the present invention has an advantage in that a standard rectangular pipe can be easily used as a stock bar merely by cutting the pipe to a desired length.
