So many construction accidents in high buildings remind us to be vigilant for construction safety. If related protective measures are accessible, possibility of accidents of overhead work can be greatly reduced. Therefore, the role of safety equipment to protect the lives and safety of construction workers should be emphasized. However, due to the defects of long installation and poor safety of the traditional makeshift protective railing installa-tion, construction workers are not well protected in the construction site. So it is urgent to improve the performance of protective equipment, and pro-mote the protective railing stereotyping, tooling and standardization.%每年发生的多起建筑高处作业事故提醒我们要对施工安全时刻保持警惕。如果高空、孔洞、临边防护措施相对比较到位,就能大大降低高空坠落事故发生的可能性。因此,我们要重视安全防护用具在保护施工作业人员生命安全中的作用,但往往由于施工现场临时搭建的扣件钢管式栏杆防护存在安装耗时长、安全性差等缺陷,导致现场施工人员的安全得不到保障。提高、改进防护用具的使用性能,促进临边栏杆防护定型化、工具化、标准化成为了建筑施工领域的迫切需求。
