1. Explosion relief wall is divided into light pressure relief wall and light fragile wall.The unit mass of light wall used as pressure relief facilities should not be greater than 0.6kN/m2. 2. Light and fragile walls are divided into three types: fiber reinforced cement board wall, expansive stone light board wall and foam concrete composite wall board. 3. Foam concrete composite slab wall is a fabricated wall structure that is connected to the main structure (reinforced concrete structure) or welded to the main structure (steel structure) by the foam concrete lightweight precast slab through the prefabricated parts. 4. The foam concrete composite panel wall is a new type of prefabricated panel, which is made of profile steel as the structural frame and fiber reinforced foam concrete mixed with additives as the core material. 5. Foam concrete composite panel wall integrates load bearing, heat preservation, sound insulation, fire prevention and explosion relief, and is characterized by light weight, high strength and factory production.It is in lump or powder form during explosion, and should not cause secondary injury. 6. The foam concrete composite plate used for explosion relief wall is usually 3 m~9 m long, 1.5 m wide, 100 mm thick, and the main frame is 160 mm~320 mm high (corresponding to the plate length).When the common specifications cannot meet the engineering design requirements, the manufacturer can produce non-standard plate types that meet the engineering needs according to the actual situation. 7. The selection of steel for foam concrete composite slab wall, structural design principles and basic structure, processing, manufacturing, construction and installation requirements shall be in accordance with enterprise standards.
