Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a temporary protective railing for a bridge. Background Art

[0002] With the development of society and the advancement of science and technology, building guardrails are one of the important and effective measures for safety protection of the edges of construction in my country. At present, temporary guardrails are often used in municipal engineering. Temporary guardrails are suitable for temporary isolation, temporary partitions and temporary enclosures. They are mostly used in temporary construction sites of municipal roads to protect the safety of workers and remind passing vehicles and pedestrians to be safe.

[0003] Traditional building guardrails are made of steel pipes, various fasteners and protective nets. The protective nets are generally rolled up, and during installation, construction workers unroll the rolls while fixing them on the steel pipes with wire or clips. Since construction workers are always required to move the rolls during the installation process and press them on the steel pipes when fixing them, a certain amount of manpower is required, making the installation efficiency low. In addition, after use, it is inconvenient to disassemble and the protective net is easily damaged. Utility Model Content
