PURPOSE: A method for coupling a rung with a rail of a cable tray is provided to firmly couple the rung with the rail by sealing a coupling hole of a bracket by extending a fixing unit of a rivet. CONSTITUTION: A bracket is inserted into both ends of a rung(12). A lower side of one end of the bracket is depressed. Both ends of the rung are depressed. The coupling hole of the bracket is matched with the hole of a rail(13). A rivet is inserted into the coupling hole of the bracket and the hole of the rail. A fixing unit(22) of the rivet is changed to seal the hole of the rail. An outer diameter of the fixing unit of the rivet is extended to seal a fixing groove of the coupling hole. |
