<p>PROBLEM TO BE SOLVED: To provide a superstructure in which a garden room is excellent in airtightness and which has a good external appearance.SOLUTION: A superstructure includes slide type doors 6, rails 62 for guiding the doors 6, rafters 4 slopewise provided, and rail support girders 7. The rail support girder 7 includes: a support girder body 7a to which the rail 62 is fixed; and a support girder cover 7b having a substantially inverse U-shaped cross section and capable of fixing the support girder body 7a inserted from an opening by an arbitrary amount. The rafter 4 is divided at an intersection with the rail support girder 7, and the divided end part is fixed to the support girder cover 7b. The interval between the rafter 4 and the rail 62 is be adjusted by changing the insertion amount of the support girder body 7a. No clearance is generated between the rafter 4 and the rail support girder 7, airtightness of a garden room is excellent, and the superstructure has a good external appearance.</p> |
