Precautions for steel structure construction in rainy days
During the construction of the steel structure, there will be rain, at this time, we should pay attention to what should be paid attention to during the construction of the rainy day, in order to ensure the safe construction, let's take a look.
1. During construction in rainy days, it is advisable to set up a temporary protective shed, and the rainwater shall not fall on the hot weld, if the welding part is relatively wet, it must be wiped with a dry cloth and dried with an oxypylene flame before welding, so as to keep the seam dry and no residual moisture.
2. When hoisting, if there is water on the component, it should be cleaned before installation, but the coating should not be damaged, and the friction surface of the component should be clean when the high-strength bolt joint is installed, and there can be no water droplets, and it can not be rained and contact with dirt and oil and other dirt.
3. Rainy weather components cannot be painted.
4. The construction of roof insulation cannot be carried out in rainy days and winds above level <>.
5. In rainy days, due to the humid air, the electrode storage should be moisture-proof and baked, and the number of repeated baking of the same electrode should not exceed two times, and the management personnel should make a record of the roasting in time.
When we are in the steel structure rainy day, if we encounter windy weather, columns, main beams, supports and other large components should be corrected immediately, and the position correction is correct and fixed immediately after the correct position correction to prevent unilateral instability, and the components installed on the same day should form a spatial stability system.
