Abstract

Free-form buildings are composed of different curved surfaces and panels with varying curvatures used for the exterior. Because free-form curved surfaces differ from those of conventional buildings, they serve as landmarks worldwide and generate economic and social profits. However, molds used to realize the curved surfaces of free-form buildings are typically single-use, resulting in construction waste and posing limitations such as environmental pollution and increased construction costs. To address this issue, current research is focused on developing reusable forms that precisely implement free-form curved surfaces. Among these approaches, the Free-form Concrete Panel (FCP) employs reusable silicone material as a mold. The silicone mold consists of a lower part and a side part, with both parts fixed together by friction due to the same material. However, during the concrete pouring process into the silicone mold, lateral pressure can cause shifting, reducing the precision of the FCP and resulting in defective panels. To address this challenge, this study introduces the use of iron powder in the lower part and magnets on the sides to secure the form using magnetic force.
