Liu Rubing' (1.School of Architecture and Civil Engineering Taishou Polytechnic College Taizhou Jiangsu 225300 China; 2.School of Civil Engineering Southeast University Nanjing Jiangsu 210096 China) Abstract:For the plex three-dimensional surface of many cast-in-place concrete structures it is difficult to determine the formwork shape and size from the construction drawings.Therefore establishing the three-dimensional model of the whole structure using CAD technology is needed to acquire the formwork shape and size and solve the difficulty of plex surface formwork lofting.For replacing curve by straight line method the influence of the curvature of a surface and the allowable deviation on the size of segmental formwork was analyzed meanwhile some principles and methods of vertical formwork segment were put forward.Combined with two project examples the design method and step of surface formwork using CAD modeling technology were also introduced. Key words:formwork surface...
