《施工现场临时建筑物技术规范》JGJ/T188-2009和《建筑施工安全检查标准》JGJ59-2011中都对围挡做出了规定，但两个规范各自的适用范围却不一样：JGJ/T188用于临时建筑的围挡；而JGJ59用于工程施工的围挡，是为了预防现场施工生产安全事故的发生。

　　The Technical Specification for Temporary Buildings on Construction Sites (JGJ/T188-2009) and the Construction Safety Inspection Standard (JGJ59-2011) both provide provisions for enclosures, but the scope of application of the two specifications is different: JGJ/T188 is used for enclosures of temporary buildings; JGJ59 is used as a fence for engineering construction to prevent the occurrence of on-site construction safety accidents.
