<p>PURPOSE:To prevent lowering of the strength of a joint by locating a jointing metal, having rigidity, to the joint forming the root part of a roof panel the facing material of which is stuck to a frame body in a U-shape in cross section. CONSTITUTION:A facing material 2 is stuck to a frame body 1 in a U-shape in cross section to form a roof panel 3. A joining metal A in the shape of a hat in cross section having rigidity is located to a joint forming the root part of a roof built by using panels 3 and is joined thereto by means of bolts 10. The shape of the jointing metal A is differed with structure of the root part. This structure burdens a load even by the joint and eliminates a structural weak point.</p> |
