摘　　要：六旗山水文园项目标志塔由于其建筑造型的特殊性,采用钢筋混凝土结构与钢结构相结合的结构形式。项目施工中,在狭小空间中支模成为施工的重难点,对此,采用型钢梁+压型钢板作为15.0 m层梁板支模体系,解决了施工中支模高度超高、高宽比受限制的问题,降低了标志塔建筑物施工的难度,保证了施工安全。总结的施工方法可为类似项目借鉴。Due to the particularity of its architectural form,the sign tower of Liuqi Shanshui Cultural Park project adopts the structural form of combining reinforced concrete structure with steel structure.During the construction of the project,the formwork support in the narrow space has become the key and difficult point.In this regard,the steel beam and profiled steel plate is adopted as the beam slab formwork support system of 15.0 m layer,which solves the problems of super high formwork height and limited height width ratio in construction,reduces the construction difficulty of the sign tower building,and ensures the construction safety.The summarized construction methods can be used as reference for similar projects.
