With the continuous progress of engineering technology, large
Steel Plate Warehouse as an important part of modern storage facilities, its construction scope is increasingly wide.However, the construction of large steel plate
warehouse in the cold winter, not only facing the technical challenges of low temperature, but also need to pay special attention to construction safety and quality control.In this paper, we will discuss in detail the precautions and safety strategies for the construction of large steel plate warehouse in winter from the aspects of material preparation, construction technology, thermal insulation measures, safety management.
一，material preparation and protection
1. steel plate and accessories of insulation and preheating Winter construction, low temperature environment, the brittleness of the steel plate increases, easy to lead to welding cracks and other problems.Therefore, before construction, the steel plate and accessories should be necessary thermal insulation, such as the use of thermal insulation blanket package to reduce heat loss.At the same time, for steel plates that need to be welded, preheating treatment should be carried out to improve welding quality and reduce welding stress.
2. Selection and construction of anti-corrosion coatings Low temperature will affect the curing effect of anti-corrosion coatings, so anti-corrosion coatings suitable for use in low-temperature environments should be selected and constructed in strict accordance with the temperature conditions required by the manual.If necessary, heating equipment can be used to increase the temperature of the construction environment, to ensure uniform curing of the coating to achieve the desired anti-corrosion effect.
二，the construction process adjustment
1. Welding process optimization Winter welding needs to adjust the welding parameters, such as increasing the welding current, appropriate slow down the welding speed, in order to reduce the cooling rate of the welded heat-affected zone, to avoid cracks.At the same time, strengthen the heat preservation and slow cooling measures after welding to ensure the quality of the weld.
2. Installation sequence and progress control Reasonable arrangement of the installation sequence, prioritize the completion of the closed structure part, in order to reduce heat dissipation and improve the temperature of the construction area.At the same time, flexibly adjust the construction progress according to the weather conditions and material properties to avoid working under extreme cold weather.
三， Heat preservation measures
1. Construction area closure and heating Use materials such as tents and insulation boards to close the construction area and reduce the intrusion of cold air from outside.At the same time, heating equipment can be installed, such as heaters, electric blankets, etc., to improve the temperature of the construction environment and ensure normal operating conditions for construction personnel and materials.
2. Concrete pouring and maintenance If the construction involves concrete pouring, measures such as heating the mixing water and raising the temperature of the concrete mixture should be taken to ensure that the temperature of the concrete in the mold is not lower than the specified requirements.After pouring, cover the insulating material in time and strengthen the maintenance to prevent the concrete from freezing.
四， Safety Management
1. Strengthen safety education Before construction, conduct winter construction safety education and training for all construction personnel to improve safety awareness and master the characteristics of winter construction and emergency handling skills.
2. fire and explosion-proof management Winter construction using more heating equipment, need to strengthen the fire and explosion-proof management to ensure the safe use of equipment, prohibit the use of open flame or storage of flammable items in flammable and explosive areas. 3. emergency preparedness.
3. Emergency preparedness Formulate emergency plan for winter construction, equip with necessary emergency rescue materials and equipment, and organize regular emergency drills to ensure rapid and effective disposal in case of emergencies.
In short, the winter construction of large steel plate warehouse is a complex and arduous task, which requires the construction unit to start from the preparation of materials, construction technology, thermal insulation measures, safety management and other aspects, to take effective measures to ensure construction safety, quality and progress.Only in this way can the construction task be successfully completed, laying a solid foundation for the safe and stable operation of the storage facility.
