The reinforcing beam and the end ceiling beam are fixed by a connecting beam extending perpendicularly to the end ceiling beam from the back side of the side surface on which the support bracket is provided.

[0006]

According to the roof unit support structure of the first aspect of the present invention, the support bracket is projected to the side of the opposite end beam, and the roof unit and the living room unit are viewed on the support bracket in plan view. Since it is mounted in a state where it does not overlap, it does not interfere with other roof units installed on the living room units on both sides, and it is possible to form a roof with good appearance without unevenness at the joints thereof with other roof units.
Further, even if the load of the roof unit is applied to the support bracket, the load is transmitted to the vertical columns and the like of each living room unit via the gable ceiling beam, so that the support rigidity can be secured. In addition, since the support bracket is located on the ceiling and is not large, it is located at the lower end of both ends of the roof unit, so that the appearance is not noticeable. When the space is the same size as the living room unit, a roof unit having the same shape as the roof unit on the living room unit can be used.

Further, a reinforcing beam parallel to the girder ceiling beam is provided between a pair of long girder ceiling beams fixed at right angles to both ends of the girder ceiling beam. Since it is fixed by a connecting beam extending perpendicular to the wife ceiling beam from the back side of the side where the bracket is projected, the load of the roof unit applied to the wife ceiling beam from the support bracket is directly to the reinforcing beam via the connection beam. In addition, the support load of the roof unit applied to the support bracket can be sufficiently supported.
