<P>PROBLEM TO BE SOLVED: To provide a roof structure which can make simple a structure of a beam that supports a roof of a structure with a plant facility installed indoors. <P>SOLUTION: A beam member 22 supporting a roof board 20 from below is supported by a stair shaft 38D which supports a stair part 38 provided in a roof structure 30. Thus by supporting the beam member 22 using the stair shaft 38D, the structure of a roof frame 18 can be made simpler compared to the case when the beam member 22 is not supported using the stair shaft 38D. For example, because the beam member 22 is supported in a plurality of sites by using the roof structure 30, the support span in the beam member 22 is reduced, so as to change the beam from a truss beam to a beam using a H-shape steel. <P>COPYRIGHT: (C)2013,JPO&INPIT |
