大模板在美国及欧洲各国应用颇广,它是随着大型起吊设备及运输机具的发展而出现的产物。在有起吊设备可利用时,大模板是经济的。特别是在高层建筑中,大模板可以多次重复使用,其经济效果尤为显著。用普通模板浇捣的墙面,无论是现场支模或预制模板块体拼装,都需搭脚手,需要墙面粉刷抹灰找平,这就需要耗用大量的人工,施工期长;而大模板浇捣的墙面,如模板面层经过处理,这一道工序就可以省掉,仅在墙面上喷色浆就可以使用。一般说,这些人工操作费用,都大大超过大模板的机械使用费用。另外,装模拆模,在起吊设备的操作条 The large formwork is widely used in the United States and European countries. It is the result of the development of large-scale lifting equipment and transport equipment. Large panels are economical when there is lifting equipment available. Especially in high-rise buildings, large templates can be used repeatedly and their economic effects are particularly significant. The wall surface that is cast with ordinary formwork, no matter if it is a site mold or prefabricated formwork block assembly, it is necessary to build a footer, which requires plastering the wall and plastering and leveling. This requires a lot of labor, and the construction period is long; The template-casting wall surface, such as the surface layer of the template, can be omitted. This process can be used only by spraying color paste on the wall surface. Generally speaking, these manual operation costs greatly exceed the mechanical usage cost of the large formwork. In addition, loading and unloading the mold, the operating device in the lifting equipment
