Kbq1, Kbq2 Explosion-proof Wall System Construction, Atlas 14j938 Standard Construction, Suyun Industrial Explosion-proof Board
Explosion-proof wall design
1. The explosion-proof wall shall be made of non-combustible materials and shall not be used as a load-bearing wall. Its fire resistance limit shall not be less than 4h.
2. The explosion-proof wall can be a reinforced brick wall. When there are more production personnel or more valuable equipment in the adjacent rooms, a cast-in-place reinforced concrete wall should be used.
3. The thickness of the reinforced brick wall shall be determined by structural calculation, but it shall not be less than 240mm. The strength of the bricks shall not be lower than MU7.5, and the strength of the mortar shall not be lower than M 5.
Structural reinforcement: Along the height direction of the wall, 3Φ6 - 10 long horizontal steel bars shall be arranged every 500mm. Their two ends shall be bound or welded with the embedded steel bars of the reinforced concrete frame or bent columns. When the length and height of the brick wall are greater than 6m, intermediate reinforced concrete columns and beams shall be provided and reinforced according to the structure. The concrete strength grade shall not be lower than C15, and its ends shall be connected with the roof beams, frames and bent columns; The thickness of the reinforced concrete explosion-proof wall shall not be less than 180mm, and the concrete strength grade shall not be less than C20. The cross-sectional area of the steel bars shall be determined by structural calculation; It is not advisable to open holes in the explosion-proof wall. When process pipes, cables, etc. must pass through, the holes shall not be larger than Φ200mm. Reinforcing steel bars shall be arranged around the holes, and the holes shall be filled and sealed tightly.
