Constructing Lightweight Steel Structures in the Rainy Season

The arrival of the rainy season presents a significant challenge for the construction of lightweight steel structures. During this period, it's crucial not only to maintain the pace of construction but also to ensure the quality and safety of the work. This article will introduce key measures to consider when installing lightweight steel structures during the rainy season and how to address the challenges brought by the rain through these measures.

When constructing in the rainy season, we adhere to the overarching principle of "adequate drainage, water blocking, and waterproofing." Our goal is to ensure that indoor projects remain unaffected by the rainy season, while outdoor projects continue in light rain, pause during heavy rain, and resume swiftly after a storm. Although the quality of construction on rainy days may be lower than on sunny days, appropriate measures can minimize this impact.

It's essential to gather meteorological information to prepare thoroughly for construction during the rainy season. Under the leadership of the technical director, technicians are responsible for compiling technical measures for rainy season construction and providing detailed guidance. Besides, steel structure project managers are in charge of coordinating the human, financial, and material resources needed for rainy season construction to ensure smooth progress.

Lightning protection is crucial during rainy season construction. All formwork must be elevated from the ground when stacked to prevent damage from water immersion. Formwork release agents should be covered with plastic sheets after application to prevent the isolation layer from being washed away by rain. For steel structure materials, effective covering is also necessary, ensuring that the storage area has a good drainage system to prevent rusting due to water immersion.

Welding work of prefabricated steel structures should not be conducted in the rain, but it can be protected by constructing processing sheds. Welding machines, wires, and gas cylinders should be stored in dedicated sheds to prevent moisture damage. During welding of prefabricated steel structures, it's important to prevent rain from affecting the quality of the welds. As for high-strength bolt installation, during the rainy season, it's essential to ensure that construction personnel have rain gear and to pay special attention to electrical safety during prefabricated steel structures construction.

Temporary electricity sites need to be protected during rain. The power should be cut off when not in use to prevent electrical accidents. For scaffolding, it's mandatory to inspect the clamps one by one before and after the rain and ensure that the foundation is solid. During inspections, construction and inspection personnel must ensure their safety measures are in place, paying attention to slip prevention and fall protection.

Although the rainy season brings many inconveniences to the construction of portal frame steel structure, by taking the aforementioned measures, we can effectively address the challenges posed by the rain. The key lies in advance preparation, scientific management, and strict implementation of safety measures. In this way, even during the rainy season, we can ensure the quality and safety of portal frame steel structures and complete construction tasks on time.
