During the construction of steel structures, there will be rainy days. At this time, what should we pay attention to in order to ensure the construction safety of the construction site in rainy days? The steel structure manufacturer will take you to have a look. 1. During the construction in rainy days, a temporary maintenance shed shall be set up, and the precipitation shall not be scattered on the hot melt welding. If the welding position is wet and cold, dry rags shall be used to wipe it clean. Before the welding, oxyacetylene flame shall be used to bake it to maintain the dryness of the joint without leaving water. 2. When lifting, if there is water on the prefabricated component, it shall be cleaned before construction, and the coating shall not be damaged. During installation, the prefabricated component shall be

1. During the construction in rainy days, a temporary maintenance shed shall be set up, and the precipitation shall not be scattered on the hot melt welding. If the welding position is wet and cold, dry rags shall be used to wipe it clean. Before the welding, oxyacetylene flame shall be used to bake it to maintain the dryness of the joint without leaving water.
2. When lifting, if there is water on the prefabricated component, it should be cleaned before construction without damaging the coating. During installation, the friction surface of the prefabricated component should be kept clean without water drops, rain, soil, oil and other dirt.
3. When the temperature is rainy, the prefabricated components cannot be painted.
4. The construction of wall insulation works cannot be carried out in rainy days and strong winds above Grade 5.

5. In rainy days, because the indoor air is very wet and cold, the welding wire should be stored waterproof and then baked. The same welding wire should not be re-baked more than twice. The manager must keep a good baking record.
For the steel structure in rainy days, in case of strong wind and temperature, the columns, beams, support points and other major prefabricated components should be calibrated immediately, and the parts should be fixed immediately after proper calibration, to prevent the occurrence of imbalance on one side and assembly of unstable prefabricated components.
Characteristics and performance of steel structure buildings
High toughness: compared with other traditional structures, steel structures are stronger than reinforced concrete, brick-concrete building structures and wooden structures. In the same design environment, the prefabricated components of steel structure are light in weight and small in cross section. Steel structure is especially suitable for large-span buildings. You can see that some large plants are mostly steel structure industrial plants.
Light weight: under the same size, the net weight of steel roof truss of steel structure industrial plant is only 1/4~1/3 of concrete, and even 1/10 of cold-formed thin-walled steel roof truss. So the light weight can reduce the force of earthquake disaster, so the steel structure industrial plant has seismic capacity.
Good ductility and flexibility: the raw material of the steel structure workshop is construction steel. The internal structure of the steel is very symmetrical, close to anisotropy, and has good plasticity and ductility. It will not break suddenly due to external forces, such as earthquake and other flood disasters.
Modernization: The characteristic of steel structure industrial plant is modernization. The construction stage of steel structure is generally to produce all the required components in the factory and then transport them to the site for assembly. Modernization can also accurately control the quality and improve the safety factor of steel structures.
Green and environmental protection: why is the steel structure industrial plant called green and environmental protection engineering building? Friends who know engineering buildings know that steel structure is a model of green and energy-saving buildings, and the rock wool color steel plate used in the steel structure industrial plant is energy-saving building materials. Another reflection of low carbon and environmental protection is to select dry work in the construction of all steel structures to prevent air pollution caused by wet and cold concrete structures.
