一种大型球形屏幕安装体系及其施工方法
摘要：
一种大型球形屏幕安装体系，包括球形屏幕和设置在球形屏幕内侧的施工平台。所述球形屏幕包括呈圆弧形间隔设在地面上的支撑柱、水平连接在支撑柱顶面的下弦弧形梁、设在下弦弧形梁正上方的赤道弧形梁、连接在下弦弧形梁和赤道弧形梁上的球形钢结构网架和连接在球形钢结构网架内球面上的金属屏幕；所述金属屏幕包括对应设在上部网架上的上部金属屏幕、对应设在中部网架上的中部金属屏幕及对应设在下部网架上的下部金属屏幕。本发明的安装方法可用于大型4D影院球形屏幕钢结构网架和金属屏幕的安装。
摘要（英）：

A large spherical screen mounting system comprises a spherical screen and a construction platform arranged on the inner side of the spherical screen. The spherical screen comprises supporting columns arranged on the ground at intervals in an arc shape, a lower chord arc-shaped beam horizontally connected to the top faces of the supporting columns, an equator arc-shaped beam arranged over the lower chord arc-shaped beam, a spherical steel structure net frame connected to the lower chord arc-shaped beam and the equator arc-shaped beam, and a metal screen connected to the inner spherical surface of the spherical steel structure net frame. The metal screen comprises an upper metal screen body arranged on an upper net frame body correspondingly, a middle metal screen body arranged on a middle net frame body correspondingly, and a lower metal screen body arranged on a lower net frame correspondingly. A mounting method of the large spherical screen mounting system can be applied to mounting of a spherical screen steel structure net frame and a metal screen of a large 4D cinema.
