Fabricated roof with partially-coated composite beams and construction method of fabricated roof
The invention discloses a fabricated roof with partially-coated composite beams. The fabricated roof is characterized in that the fabricated roof comprises the partially-coated composite beams, the partially-coated composite beams are bilaterally-symmetrical folding beams and are simply arranged at the top of a frame column, rigid tie bars are perpendicular to the partially-coated composite beamsand are arranged at a sloping position, a ridge and a wind-resistant column of the roof, the horizontal supports are arranged in two spans of the end, the partially-coated composite beams are connected with the wind-resistant column through a spring plate, and the partially-coated composite beams are connected with the rigid tie bars through gusset plates in a welded mode. The fabricated roof is suitable for a large-span roof structure, and the partially-coated composite beam is prefabricated in a factory and hoisted on site; compared with a pure steel beam, anti-corrosion and fireproof coating on the inner sides of a steel web and flanges is omitted, coated concrete can prevent local buckling of the web and local buckling of the flanges towards the inner sides, and the flexural rigidity of the composite beam is improved.
本发明公开一种带部分包覆组合梁的装配式屋盖，其特征在于：所述装配式屋盖包括部分包覆组合梁，所述部分包覆组合梁为左右对称折梁，简支布置于框架柱顶，刚性系杆与部分包覆组合梁垂直，布置于屋面起坡处、屋脊和抗风柱处，水平支撑布置在端部两跨内，部分包覆组合梁与抗风柱通过弹簧板连接，部分包覆组合梁与刚性系杆通过节点板焊接连接。本发明的装配式屋盖适用于大跨度屋面结构，其中部分包覆组合梁工厂预制，现场吊装，与纯钢梁相比，省去钢腹板及翼缘内侧的防腐防火涂料，包覆混凝土能阻止腹板的局部屈曲和翼缘向内侧局部屈曲，组合梁抗弯刚度增大。
