Accordingly, the structural steel 300, which is not supported by a middle structure not provided with a refractory structure but instead serves as a middle steel such as a C-shaped steel, is hidden inside and is integrally set, And the roof of the building is supported. Thus, when a fire occurs, the length of the midway crossing the roof support beam 10 is extended to a length of about 5 to 10 m as in the conventional case. The present invention provides a roof system having a refractory structure capable of minimizing thermal deformation of the entire structure and preventing collapse of the roof without being twisted or bent and collapsed by thermal deformation due to thermal deformation can do.
