桥式脚手架是70年代初期建筑施工脚手架的一项科技成果。过去由于管理、操作等原因,在桥式脚手架使用时发生过一些事故,因此研制一种操作简便、技术可行、安全可靠的安全装置,是推广桥式脚手架急需解决的重要课题。我公司近年来对桥式脚手架安全装置进行了研究,设计了一套安全装置,经试用证明性能较好。一、功能这套安全装置由自动保险和手扳联动销两套机构组成(图1),具备以下三种功能:
Bridge Scaffolding is a scientific and technological achievement of construction scaffolding in the early 70s. In the past, due to management, operation and other reasons, some accidents occurred during the use of bridge scaffolding. Therefore, the development of a safety device that is easy to operate, technically feasible, safe, and reliable is an important issue that needs to be solved urgently for the promotion of bridge scaffolding. In recent years, our company has carried out research on safety devices for bridge scaffolds and designed a set of safety devices that have proved to be of good performance after trials. First, the function This set of safety devices consists of automatic insurance and hand-pull linkage pin two sets of institutions (Figure 1), with the following three functions:
