ROOF CONSTRUCTION METHOD OF BUILDING

PURPOSE:To make it possible to execute economically easily and safely without forming any scaffold. CONSTITUTION:Ribs 3 of a roof are made in a channel shape to arrange a large number of horizontal bars 6 in the channels of the ribs 3 at proper intervals, and plate-like legs 12 are provided on both sides downward of the bodies of tiles 10 to form hook-shaped cuts at the lower edges of the legs. After a framework of a building is assembled with columns, beams, ribs 3, etc., the tiles 10 are subsequently arranged from the bottom to the top of the ribs 3 through a map between the ribs 3. After both side legs 12 of the tiles 10 are respectively fitted to the insides of the channels of the ribs 3 on both sides to interlock the hook-shaped cuts of both side legs with the horizontal bars 6 of the ribs 3, the tiles 10 are properly fixed to the ribs 3 to construct the roof of the building.
