摘要
为解决传统胶合板无法塑造空间异型混凝土结构的问题,本文提出了"三维弧形悬挑结构清水混凝土施工技术"。在该施工技术中,模板采用"钢面板"+"钢龙骨"支撑系统抵抗施工过程中的变形,针对曲面法线方向上的不规则变化采用钢面板切割拼装工艺,采用电脑三维模型进行构架钢龙骨进行深化设计、放样加工制作,使T型钢龙骨构架精确模拟沿长度方向的无规则变化。充分利用构架自身的泄水孔对整个模板支撑系统进行加固,保证了结构轮廓曲线顺滑,满足清水混凝土观感的高标准要求。
The traditional plywood can’t shape space concrete structure,and therefore,this article puts forward the concrete construction technology for 3D curved cantilever structure. This construction technology uses the supporting system of ＂steel plate＂plus ＂steel keel＂to prevent deformation during construction,uses steel plate cutting and assembly techniques to solve the problems of irregular changes in the surface normal direction,and uses computer 3D modeling to carry out detailed design and sample processing for the structural steel keel,which makes T-shaped steel keel structure accurately simulate the irregular changes in the longitudinal direction. Making full use of the drainage hole of the structure itself to enhance the whole modeling supporting system,this technology guarantees that the structural curve keeps smooth to meet the high standards of concrete appearances.
