摘要: An access door assembly is for a floor structure. The access door assembly includes a door frame coupled to the floor structure and defining an opening aligned with a staircase, and an access door within the opening and having first and second longitudinal sides. The first longitudinal side defines a first opposing bevelled surface, and the floor structure adjacent the opening defines a second opposing bevelled surface. The access door assembly also includes an arm coupled to the access door and configured to pivot the access door between an open state and a closed state. The first and second opposing bevelled surfaces are aligned and abutting in the closed state, and are in spaced apart relation in the open state.
