    • 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).
    • 技术领域本发明总体上涉及一种屋顶结构(10),其包括分别由多个顶部和/或底部包层板(14A / B)和(16A / B)互连的多个屋顶桁架(12)。 每个桁架(12)包括通过多个腹板构件(22A / B)互连的顶弦构件(18)和底弦构件(20)。 每个桁架(12)具有可伸缩的底部弦杆(20),并且因此可变长度以允许屋顶桁架(12)的移动和重新配置。 在屋顶结构(10)的竖立期间,顶部和底部屋顶覆盖板(14A / B)和(16A / B)偏转以适应每个屋顶桁架(12)的位移和底部弦杆构件(20)的缩回 )。
