Some Details on Steel Structure Construction During Winter and Rainy Seasons

Each season has its own characteristics: summer is hot and rainy, winter is dry and cold. Today, we will discuss some details regarding construction during winter and the rainy season. First, let's take a look at winter construction.
During component cutting, allowance for contraction should be left. The contraction and compression deformation during welding, as well as the contraction deformation of steel structures within these two domains under negative temperature conditions, should be coordinated.
(2) During assembly, components should be assembled from the inside out as per regulations. Negative temperature assembly is used to maintain the shrinkage value of the weld seam. The weld seam should be kept clean and tidy.
(3) For steel plates thicker than 9mm in sub-zero temperatures, multi-layer welding should be employed, with the weld seams being layered from bottom to top. After each layer is completed, it should be inspected, and only after no welding defects are found can the next layer be焊接.
(4) During steel structure installation, protective sheds must be set up in case of rainy, snowy, or windy weather.
(5) If the environmental temperature is below freezing, test for any issues prior to applying the anti-rust paint. And clean the component surfaces before washing them.
(6) When transporting and stacking steel structures, anti-slip measures should be taken. Maintain a level and firm site. Keep components stacked horizontally. (7) Before installation, inspect the quality of the steel structure; promptly repair and correct any issues found.
Prepare and strictly adhere to the steel structure installation sequence diagram.
When welding steel structures, the ends of the components cannot be welded simultaneously.
Ensure cleanliness when installing bolts.
What are the details for steel structure construction during the rainy season?
Set up temporary protective shelters to maintain the weld seam dry.
(2) Component painting should cease, and roof insulation should be halted.
(3) Welding rods should be stored in a moisture-proof environment and should be dried before use. The number of baking times for a single welding rod should not exceed two.
(4) In the event of strong wind conditions, some large components should be adjusted and then securely fastened to maintain stability.
