1. Unloading and stacking of warehouse boards
After the vehicles transporting warehouse boards arrive at the construction site, they should be unloaded in an organized manner and classified neatly according to the type and size of the warehouse boards. When stacking, place anti-scratch protective materials on the floor and between each layer of the warehouse board. During the process of unloading and stacking, handle with care, and it is strictly forbidden to throw, drag and other rough handling to avoid scratches on the warehouse board and outer protective film; the appearance quality of the warehouse board should be checked for scratches, pits, bulges, etc. Defects: stacking must be classified and arranged neatly, and warehouse boards found to be out of tolerance are stacked separately and marked.
2. Statistics and acceptance of warehouse boards
According to the purchase order details and design drawings provided by the design department or supply department, arrange for a dedicated person to count the quantity and specifications of the warehouse boards that have arrived. Check the appearance and density of the warehouse boards and keep records; warehouse boards with serious quality defects should be reported to the project manager or on-site technical personnel in a timely manner to make a decision to replace the goods or allow use.
3. Floor insulation construction
Cold storage is different from general industrial and civil buildings. The temperature difference between the inside and outside of the cold storage and the water vapor partial pressure difference affect the normal operation of the cold storage, so it should be done carefully A good floor air-insulation, moisture-proof and thermal insulation project; after arriving at the construction site, the construction personnel should carefully compare the design drawings to check whether the underground ventilation ducts comply with the drawing design, whether the air-insulation and moisture-proof layer is flat and complete, whether the size meets the requirements of the drawings, and whether the XPS of the insulation material Whether the density and overall dimensions comply with the drawing requirements and product specifications. When laying XPS insulation boards, they should be arranged in staggered seams. Excessively large gaps should be filled with foam. When laying plastic sheets, they should be smooth and without leaks. The wall panel installation groove should be straight and the debris should be cleared away. The construction work of 100-thick C20 reinforced concrete should be carried out strictly in accordance with the technical requirements of the drawings to ensure the long-term and safe operation of the cold storage.
4. Inspection and preparation of the construction site
Prepare tape measure, level, string, transparent plastic pipe and other auxiliary tools, check the ground of the construction site against the design drawings Or the construction accuracy of the thermal insulation floor, including flatness, dimensional accuracy and elevation accuracy of the warehouse area, etc.; protect the embedded parts and embedded pipelines and clearly mark them; thoroughly clean the wall panel installation trench, and cooperate with Civil construction workers correct trench errors.
5. Preparation of construction equipment and auxiliary materials
According to the actual conditions of the construction site, prepare hydraulic lifting trolleys, scaffolding, safety belts and other construction equipment and tools, and according to the construction progress Collect various auxiliary materials used on duty.
6. Construction organization
All personnel at the construction site should wear uniformly distributed work clothes and necessary protective equipment; each working surface should obey the unified command of the on-site commander and cooperate closely Work.
