大面积超高倾斜清水混凝土剪力墙模板体系的选型及应用

Selection and Application of the Formwork System for Large-area Super-tall Inclined Fair-faced Concrete Shear Wall

三峡移民纪念馆工程体形复杂,工程通过空间立面和空间直线组成的清水混凝土结构来表达建筑效果,工程通过51面不同角度的斜墙和8面双夹墙组成7个不同的形似巨石的构筑物,营造长江三峡陡壁长峡的效果。清水混凝土墙体均为大面积超高倾斜墙体。针对工程特点,结合国内清水混凝土工程实例,从适用性、质量、工期、经济性等多方面要求综合考虑,对比选择模板体系,最终达到保证施工质量、缩短工期、节约成本的目的。

The Sanxia Migration Memorial Hall has a complicated geometry.Its architectural effect is expressed by fair-faced concrete structure,which consists of spatial elevations and straight lines.51 inclined walls and 8 double jacketed walls form seven different structures that look like huge rocks to resemble the cliffs of the three gorges.The fair-faced concrete walls are all large-area super-tall inclined walls.According to the engineering characteristics,combined with other fair-faced concrete engineering examples,the authors compared different formwork systems from the aspects of applicability,quality,construction time limit and economical efficiency,etc.The formwork system selected ensured the construction quality,shortened the construction time and saved the cost.
