S.I.D.E.C.社による鉄筋コンクリート造屋根付き市場群の研究

史料に基づく企業沿革の把握と旧仏領インドシナに建設された８つの市場の屋根架構の比較

This article examines eight reinforced-concrete covered markets built by S.I.D.E.C. in former French Cochinchina and Cambodia (1920s–1930s). Combining archival records with field surveys, it reconstructs construction practices and compares roof structures. It identifies an on-site precasting workflow—perforated purlins and flat concrete tiles cast on the ground and installed as repeatable units—that enabled efficient, climate-responsive assembly under local labor and equipment constraints. The markets show a family resemblance in framing and roofing, indicating partial standardization across projects. While full interchangeability cannot be verified for all sites, the study clarifies S.I.D.E.C.’s role in adapting reinforced concrete in colonial Southeast Asia.
