异形曲面清水混凝土模板设计与施工技术——以重庆广阳岛大河文明馆为例

Design and construction technology of special-shaped curved fair-faced concrete formwork:A case of Great River Civilization Hall on Guangyang Island in Chongqing

随着清水混凝土建筑技术的发展,清水混凝土建筑造型设计越来越复杂,异形复合曲面的应用对施工技术提出了更高的要求。基于广阳岛大河文明馆异形曲面清水混凝土组合壳肋结构,展开了曲面背楞设计、曲面模板设计、曲面模板支撑结构设计、支撑体系设计、彩色清水混凝土制备、三维钢筋设计及混凝土浇筑工程。结果显示,通过异形曲面清水混凝土模板高质量设计及施工,提升了曲面清水混凝土浇筑质量,呈现了丰富的彩色清水混凝土曲面建筑艺术效果。

With the development of fair-faced concrete building technology,the design of fair-faced concrete buildings is becoming more and more complex,and the application of special-shaped composite surfaces puts forward higher requirements for construction technology.Based on the special-shaped curved surface fair-faced concrete composite shell rib structure of the Great River Civilization Hall on Guangyang Island,the curved surface back flute design,curved surface template design design,curved surface template support structure design,support system design,color fair-faced concrete preparation,three-dimensional steel bar design and concrete pouring engineering were carried out.The results show that the pouring quality of the curved fair-faced concrete is improved through the high-quality design and construction of the special-shaped curved fair-faced concrete formwork,and the rich artistic effect of the curved surface of the colored fair-faced concrete is presented.
