[0002] Building construction refers to the production activities during the implementation phase of an engineering project. It is the process of building various types of buildings, or the process of turning the lines on design drawings into physical objects at designated locations. It includes foundation construction, main structure construction, roof construction, and decoration construction. During the construction of high-rise buildings, to prevent tools and other items from falling and to prevent construction workers from falling, edge guardrails are usually installed at the edges of the high-rise buildings. In existing technology, edge guardrails are usually fixed to the edges of high-rise buildings by construction workers using expansion bolts. Although edge guardrails can prevent people from falling and ensure the safety of construction workers, the protective effect of the guardrails is not yet effective during the installation process at the edges of high-rise buildings. Therefore, the safety of the installers cannot be well guaranteed during the installation process. Therefore, to address the above problems, a guardrail for building construction is proposed.
