Post-construction steel structure assembly type cinema stand structure

The utility model relates to a post-construction steel structure assembly type cinema stand structure. The structure is characterized by comprising an original concrete beam, a steel column, a steel beam, a horizontal riffled plate and a vertical riffled plate, the horizontal riffled plate and the vertical riffled plate form a step shape and are welded on the steel beam, the steel column and the steel beam form a frame stress system, the steel column is supported on the original concrete beam, and the steel column is supported on the original concrete beam. The steel has the characteristics of light weight and high strength, so that the section of the component is small, and the overall self-weight is small; the steel structure is manufactured in factories and assembled on site, and the construction progress is accelerated. 本实用新型是一种后施工钢结构装配式影院看台结构；其特征是：包括原混凝土梁、钢柱、钢梁、水平花纹钢板、竖直花纹钢板，所述水平花纹钢板与所述竖直花纹钢板组成踏步形状"﹁"焊接在所述钢梁上，所述钢柱与所述钢梁组成框架受力体系，所述钢柱支撑在所述原混凝土梁上，由于钢材具有轻质高强的特点，构件截面比较小，整体自重较小；钢结构工厂制作现场拼装，加快了施工进度。
