Prefabricated self-supporting building structure

A method of erecting a building structure comprising the steps of:

• i) providing a plurality of substantially triangular shaped panels;
• each said panel having a front edge, a straight top edge, a straight hypotenuse edge and a junction point at an intersecting end of said hypotenuse edge and said front edge;
• ii) connecting said panels connected in juxtaposed pairs by a hinge connection means interconnecting said top edge of each juxtaposed pair of panels to form a collapsible roof segment;
• iii) connecting a further panel which is to form an adjacent roof segment on opposed sides of said roof segment with a further hinge connection means interconnecting adjacent straight hypotenuse edges of each said juxtaposed panels of said roof segment and a respective one of said further panels of adjacent roof segments to be formed to form a pre-assembled collapsible panel section;
• iv) forming a second of said pre-assembled collapsible panel sections;
• v) connecting an attachment means at said junction point of said roof segments of said two panel sections to a support means and providing a pivotal connection;
• vi) connecting a pulling cable to a connector means at a forward end of said top edge of said roof segment of said two panel sections;
• vii) erecting said two panel sections back-to-back by pulling on said cable with said further panels of each said two panel sections having their straight top edge at right angles to said straight top edge of its associated roof segment;
• viii) securing adjacent ones of said top edge of said further panels with ridge capping means to form a roof structure having four roof segments disposed at right angles to one another.
