Description

Technical Field

[0002] With the rapid development of my country's economy, steel structure building projects are also developing towards high-rise and super high-rise buildings. Therefore, high-altitude operations are inevitably required during the installation and construction of steel structures.

[0003] To ensure the safety of construction workers, safe and convenient protective devices are needed for their passage during high-altitude operations. Currently, the most common protective device is the column-type safety rope protection device. This device uses two columns installed on the upper flange of an I-beam, with a steel wire rope strung between them as a safety measure. However, the traditional column-type safety rope protection device has a simple fixing method, usually relying solely on tightening bolts to connect the columns and the I-beam. As the protection device is used, the reinforcement effect of the tightening bolts gradually decreases, reducing the stability of the column-type safety rope protection device. This may lead to the risk of the columns loosening, indicating a significant deficiency. Utility Model Content
