超大空间造型墙面施工技术研究和应用

Research and Application of Construction Technology of Modeling Metope in Super Large Space

长沙国际会议中心是由“中国馆之父”中国工程院院士何镜堂设计修建,建筑风格借鉴中国山水画“虚实相生”“远近结合”“粗细用笔”的表现手法,结合传统建筑坡屋顶的灵动造型曲线,形神兼备诠释中国文化内涵。长沙国际会议中心项目室内装饰墙面都是造型墙面,其材质种类多,造型样式多。面对该项目如此复杂且多样的造型墙面,原建筑管井及消防规范要求的消火栓等设备需预留可开启的暗门不能满足消防的验收规范,消防验收规范中要求开启角度≥120°[1]。因此,造型墙面暗门开启方式需深入研讨并最终明确构造做法,其施工作业及验收检测均需按照国家规范基础上的评奖规范要求完成[2]。

The Changsha International Convention Center was designed and built by He Jingtang, the Academician of Chinese Academy of Engineering, who is also the “Father of the China Pavilion”. The architectural style draws on the techniques of Chinese landscape painting, such as “the combination of the virtual and the real”, “the combination of the near and the far”, and “the combination of thick and thin brush”, by using the flexible curve of the traditional architectural sloping roof to annotate the connotation of Chinese culture with the unity of form and spirit. Indoor decoration metope of Changsha International Conference Center Project is modeling metope with material variety and modeling style. In the face of such a complex and various styles of the project modeling metope, the building pipe wells, fire hydrants and other equipment required by the fire code need to reserve the hidden door opening, while the original plan can not meet the acceptance specification on fire protection, because the opening angle is required to be ≥ 120 ° in the fire acceptance specification. Therefore, the opening mode of the hidden door on the molding metope needs to be studied in depth and the construction method should be determined finally, because its construction operation and acceptance inspection need to be completed in accordance with the requirements of the award specification based on the national regulations.
