Construction method of insulation layer1

1. After the waterproof and moisture-proof layer is completed, it is required that the insulation material should be tightly attached to the top of the floor. If the top is severely uneven or cannot be tightly attached, a flat and sturdy pressure strip must be made. Because there is no pressure strip above, a strong airflow is generated when the air cooler is started, which can easily tear the seams of the insulation material. Causing air leakage and lack of insulation. If the span of the roof exceeds 4 meters, it is necessary to install plywood, wooden beams, etc. to ensure safety

The warm material is tightly attached to the top of the floor. The bonding of insulation materials adopts polyurethane on-site foaming bonding, and local joints can be repaired with simple foaming agent. 23. The installation of the warehouse door should be level with the exterior wall. First, remove the door from the door frame, fix the door frame in the door opening with a cylinder filled foam agent, and then proceed with the second bonding after curing until all the seams around the warehouse door are full and sufficient.

Attention: The size of the door opening should not exceed 2cm above the size of the door frame in all directions. Installation of the bottom of the warehouse: After the wall and top are completed, the bottom is usually filled with leftover material cut off, and then filled with bulk foaming agent. After filling the joints, waterproof rolls are used to flatten them, and the joints are treated with glass fiber cloth or 20cm wide rolls and water-based waterproof coating or waterproof adhesive. Then, a layer of waterproof coating is applied, followed by a 2cm thick cement mortar protective layer. After drying, the steel bars are tied with a spacing of 10-15cm, and concrete is made with a thickness of more than 6cm. After drying for 48 hours, the machine can be turned on to cool down to 0 ℃. After 24 hours, the temperature can be reduced to -20 ℃
