大面积群体建筑屋面开放系统分形协同建造关键技术

Key Technology of Fractal Cooperative Construction of Large-area Group Building Roof Open System

国家网络安全人才培训中心工程的大面积景观屋面,以分形理论为核心,将大面积群体建筑景观屋面按谢尔宾斯基地毯进行平面分形分仓,形成了不同层级的自相似分仓单元,同时结合空间距离法对屋面施工方案进行优选,对不同层级自相似分仓单元节点进行技术攻关,保障屋面系统开放、防止屋面开裂渗漏。大面积景观屋面施工是基于条形分仓的分形迭代,对纵横分水线、排水沟、耗散结构装置、条形分仓等分形节点进行技术攻关,进一步控制景观屋面的渗漏风险。研究表明:大面积群体建筑屋面开放系统分形协同建造技术,可降低屋面渗漏风险。

The large area landscape roof construction of the national network security personnel training center project is based on the fractal theory.The large area group building landscape roof is divided into planar fractal silos according to Sherbinski carpet,and the self-similar silo units at different levels are formed.At the same time,the roof construction scheme is optimized by combining the spatial distance method.The technical research on the nodes of the self-similar silo units at different levels is carried out to ensure the opening of the roof system and prevent the roof cracking and leakage.Large area landscape roof construction is based on the fractal iteration of strip silos.The fractal nodes such as vertical and horizontal water distribution lines,drainage ditches,dissipative structure devices and strip silos are studied to further control the leakage risk of landscape roof.The research shows that the roof open system fractal cooperative construction technology has low roof leakage risk.
