Description

Technical Field

[0001] The invention relates to the technical field of building safety equipment, and in particular to an anti-falling device and method for a steel purlin. Background Art

[0002] Steel purlins refer to purlin structures made of steel. Purlins are part of the roof structure of a building, located at the bottom of the roof, used to support and connect the roof trusses or beam-column system. Traditionally, purlins are usually made of wood, but in some cases, steel can also be used to make purlins stronger and more durable.

[0003] Using steel to make purlins has the following advantages: Strength and durability: Steel has excellent strength and durability and can withstand large loads and external pressure. This makes steel purlins more reliable in resisting natural disasters (such as storms) and other adverse conditions. Light weight: Compared with wood, steel has a low specific gravity, so using steel purlins can reduce the weight of the entire roof structure. This is very useful for large buildings or roofs that require long spans.
