摘　　要：在2m厚板的结构转换层施工中,重点解决了模板支撑系统、合理安排钢筋就位次序、水平施工缝处理、混凝土防裂等难题,采用“斜面分层布料、薄层浇注振捣、分层浇筑成型”的方法浇筑大体积混凝土,严格控制混凝土内外温差,使板式结构转换层支撑系统稳定可靠,温差控制效果及混凝土观感质量好,无结构性裂缝。In the construction of 2m thick slab-type structural change-over floor, we place an emphasis on solving the template supporting system, reasonable placement sequence of steel reinforcement, treatment of horizontal construction, protection of concrete ci＇acking etc. and use the method that ＂sloping material distribution, thin layer placement and compaction, placement in layers＂ to place mass concrete, control strictly the internal and external difference in temperature, make the slab-type structural change-over floor stable and reliable, it is of high quality that the difference in temperature controls result and concrete appearance, and there is no structural crack.

关 键 词：厚型 板式结构转换层 模板支撑 大体积混凝土 温差控制
