国家大剧院北门厅弧形曲面吊顶改造

RENOVATION OF THE CURVED AND CURVED CEILING OF THE NORTH ENTRANCE HALL OF THE NATIONAL CENTRE FOR THE PERFORMING ARTS

国家大剧院北门厅原吊顶吸音效果不好,并且原设计光源暗淡,需要对吊顶进行升级改造,新吊顶采用弧形穿孔吸音石膏板吊顶加可开启弧形软膜天花,由于弧形吊顶每一条弧形的圆心和半径不一样,从中间往两侧弧度越来越小,板材加工难度大,同时改造期间国家大剧院对外开放,给施工带来了难度,通过采用先进的管理手段以及精湛的技术手段,在较短时间内完成了吊顶的升级改造。

The sound-absorbing effect of the original ceiling of the North Foyer of the National Grand Theater is not good,and the light source of the original design is dim,so the ceiling needs to be upgraded.The center and radius of each arc of the ceiling are different,and the arc becomes smaller and smaller from the middle to both sides,which makes the plate processing difficult.At the same time,the National Grand Theater was opened to the outside during the renovation,which brought difficulties to the construction.With advanced management methods and superb technical methods,the ceiling upgrade was completed in a relatively short period of time.
