The invention relates to a large-span steel structure and a metal roof integrated construction method thereof, and belongs to the technical field of steel structure building construction. Comprising a horizontally-arranged large-span steel structure beam set and further comprises a left side wall body, a middle stand column and a right side wall body which are supported on the ground, the middle stand column is located between the left side wall body and the middle stand column, and a left side bearing seat used for supporting the large-span steel structure beam set is arranged on the outer side wall body of the left side wall body; a middle combined bearing seat used for supporting a large-span steel structure beam set is arranged on the top of the middle stand column. Compared with the prior art, the large-span steel structure has the advantages that the large-span steel structure is used, the steel structure has the advantage of light self weight, meanwhile, the left side wall body, the middle stand column, the right side wall body, the left side bearing base, the right side bearing base and the middle combined bearing base have the synergistic effect, the foundation requirement is not high, and installation is convenient, the construction efficiency is high, and the construction cost is low. The construction period can be effectively shortened.

本发明涉及一种大跨度钢结构及其金属屋面一体化施工方法，属于钢结构建筑施工技术领域。包括水平设置的大跨度钢结构梁组，还包括支撑在地面上的左侧墙体、中间立柱、右侧墙体，所述中间立柱处于左侧墙体、中间立柱之间，所述左侧墙体的外侧墙体上设置有用于支撑大跨度钢结构梁组的左侧承载座，所述中间立柱的顶部设置有用于支撑大跨度钢结构梁组的中间组合承载座。本发明具有以下有益效果：通过使用大垮度钢结构，钢结构拥有自重轻的优势，同时采用左侧墙体、中间立柱、右侧墙体、左侧承载座、右侧承载座、中间组合承载座协同作用，对基础要求也就没钢筋混凝土要求高，安装方便的特性，施工效率高，能有效缩短工期。
