模板技术对混凝土工程具有十分重要的意义。不断改革的结果促使了墙体和楼板大模板(或称大面积模板)的出现。这种大模板可以周转100次以上,重量较适中,采用45吨米的普通塔式悬臂起重机即可进行吊装。大模板有三种结构形式:即组合式墙体模板,台架式楼层模板及空间结构或隧道式 Formwork technology is of great significance to concrete engineering. The result of continuous reform has prompted the emergence of large templates (or large-area forms) for walls and floors. This kind of large formwork can be turned over more than 100 times, and the weight is relatively moderate. The conventional tower crane with 45 ton meters can be used for lifting. The large formwork has three structural forms: a modular wall formwork, a platform type formwork and a space structure or tunnel type
