ROOF STRUCTURE

摘要

The present invention relates generally to a roof structure (10) comprising a plurality of roof trusses (12) interconnected by a plurality of top and/or bottom cladding panels (14A/B) and (16A/B), respectively. Each of the trusses (12) includes a top chord member (18) and a bottom chord member (20) interconnected by a plurality of web members (22A/B). Each of the trusses (12) has the bottom chord (20) retractable and thus variable in length to permit displacement and reconfiguration of the roof truss (12). The top and bottom roof cladding panels (14A/B) and (16A/B) deflect during erection of the roof structure (10) to accommodate the displacement of each of the roof trusses (12) and retraction of the bottom chord member (20).
