What are the precautions for steel structure construction in rainy days

The construction of steel structure construction must be based on safety and quality, and the first is to open the bow on both sides.The construction of steel structure can not be affected by seasons and environmental climate. When steel structure is constructed in rainy days, the following points should be paid attention to:

Set up protective shed: during construction in rainy days, temporary protective shed should be set up. Rainwater can not fall on the hot welding seam. If the welding part is wet, it must be dried with dry cloth and dried with oxyacetylene flame before welding.Keep the weld dry and show moisture residue. 

What are the precautions for steel structure construction in rainy days? 

Hoisting in rainy days: during the hoisting operation of steel structure in rainy days, if there is water on the components, clean them before hoisting. When removing rainwater, pay attention not to damage the coating.When installing the high-strength bolt joint, the surface of the component should be clean and free of water droplets, and it should not be able to bear the rain or touch the soil, so as to prevent the torque from being damaged.

Baking of welding rod: when it rains and the air is wet, the welding rod should be stored in a moisture-proof place, and it should be baked when it is used, and the same welding rod should not be baked more than three times.So in the baking time, in order to avoid repeated baking, it is necessary to make relevant records. 

Strong wind climate: in the strong wind climate, if the installation of steel structure main beam or steel column, as well as the time of supporting large components, should be corrected immediately. After correction, permanent fixation should be carried out to avoid unilateral instability. 

Of course, in the strong wind climate, if the wind force reaches level 8 or above and the cable can not control the components, the device operation should be stopped immediately.The construction of steel structure should focus on safety, with safety can have higher quality.

The above is the use of steel structure in rainy season, I hope to help you.
