<p>PURPOSE:To cut down the labor and cost of construction work by a method in which a trianglar roof panel and the adjacent triangular roof panel are connected mutually along the roof face from the end of large ridge to the eaves to form a square-conical roof. CONSTITUTION:The first roof panel 2 along the roof face Y1 and the second roof panel 3 along the adjacent roof face Y2 are connected into a triangular form between two cornor ridges S extending from the end of the large ridge M of a hipped roof, where the sloped parts of the panels 2 and 3 are joined to form a square-conical roof unit whose bottom and one side are opened. Construction cost for cornor beams and labor can be cut down.</p> |
