PROBLEM TO BE SOLVED: To provide a roof structure for allowing hangers to be easily and reliably mounted on beams.SOLUTION: In the roof structure using hangers 10 provided on beams 3 for hanging and supporting a roof body, mounting grooves 13 opened downward are formed in the lower faces of the beams 3 along the longitudinal directions and opening edges 20, 21 are formed opposing each other across the openings of the mounting grooves 13, while first engaging pieces 25 and second engaging pieces 26 protruded from the mutually opposite sides of the upper ends of the hangers 10 are formed to be bent downward. In the state that the first engaging piece 25 of each hanger 10 is put in engagement with the inside of one opening edge 20 of the mounting groove 13 of each beam 3, the hanger 10 is rotated so that the second engaging piece 26 enters into the mounting groove 13, and the hanger 10 entering into the mounting groove 13 is moved in the mounting groove 13 to put the second engaging piece 26 in engagement with the other opening edge 21 of the mounting groove 13. |
