[0002] During the wind-resistant reinforcement process of various existing construction projects, prefabricated houses used for office and living at construction sites are fixed with externally pressed steel pipes, resulting in uneven force on the house body and causing extrusion damage to the house body. At the same time, the reinforced steel pipes are exposed and exceed the scope of the house body, affecting the normal use and aesthetics of personnel. The fasteners used for steel pipe reinforcement are easily loosened due to wind vibration, posing a hidden danger to the safety of the house and personnel.

[0003] In the existing construction of various projects, improper wind-resistant roof reinforcement of prefabricated houses used for on-site office and living may cause the following hazards: 1. The roof of the prefabricated house is prone to uneven stress, causing squeezing damage to the house body; 2. The reinforced steel pipes are exposed, beyond the scope of the house body, affecting the normal use of personnel and unsightly; 3. The fasteners used to reinforce the steel pipes are easily loosened due to wind vibration, posing a hidden danger to the safety of the house and personnel. Summary of the Invention
