摘要
某影院屋面工程采用网架结构支撑压型板形式,空腔层隔声吊顶采用8层12mm厚纸面石膏板及2层玻璃棉板,中间形成650mm空腔层,空腔层上、中、下有设备管道穿插,施工交叉多,工艺复杂,施工难度较大。通过施工设计方案可行性分析,打破常规,采用一种类似串糖葫芦吊点的做法,即在网架下弦转换层增加槽钢,并改进各吊点细部做法,解决了隔声层施工技术难题。
In a roof engineering design of a cinema, grid structure is used to support the profiled sheets and sound insulation suspended ceiling is adopted in the cavity layer of the grid roof. 8 layers of 12mm-thick thistle boards and 2 layers of glass wool boards are used to for a 650mm cavity layer in the middle. Equipment pipelines pass through constructions, complex construction the upper, middle and lower parts of the cavity layer, producing many cross processes and high construction difficulties. Mter feasibility analysis of the construction and design schemes, a suspension point string connection method is adopted by setting channel steel at the lower camber transition layer of the grid and designing the details of each suspension point, and technical difficulties in sound insulation layer construction are successfully overcame.
