摘　　要：中央电视台电视文化中心舞台塔由11根型钢混凝土柱、21榀大跨度钢桁架和128根钢梁组成,因施工场地狭小,处于结构中心,无法整体吊装就位。经过对比论证,采用在工厂分段制作、整体拼装后,再分段运到现场组装,然后用塔吊高空散拼的方法进行安装,解决了桁架尺寸大、施工场地狭小等难题。The stage tower of CCTV Television ＆ Culture Center Project is composed of 11 profile steel concrete columns, 21 big-spanned steel trusses and 128 steel beams. As it is located in the center area of the building within a narrow contruction field, it cannot be hoisted to the position integrally. Through comparison and discussion, it was determined that the structure would be fabricated in sections and pre-assembled at workshop, and transported to the site in sections for assembly, then lifted to the air for erection with tower crane. This method has avoided the difficulties of large-sized trusses and narrow construction site.
