1. Explosion proof wall should be non combustible material, and should not be used as load-bearing wall, its fire resistance should not be less than 4h.

2. Reinforced brick wall can be used for explosion-proof wall. When the adjacent rooms are more productive or the equipment is more expensive, the cast-in-place reinforced concrete wall.

3. Reinforced brick wall thickness should be determined by the structure calculation, but should not be less than 240mm, brick strength should not be less than MU7.5, mortar strength should not be less than M 5.

Structural reinforcement: along the wall height direction of every 500mm configuration of 3 6-10 diameter long horizontal bars, and the ends shall be reinforced concrete frame or frame column with built-in reinforcing banding or welding. When the length and height of the brick wall is greater than 6m, the reinforced concrete columns and beams shall be provided. The concrete strength shall not be less than C15, the end should be connected with the bent roof beam and frame; thickness of reinforced concrete blast wall should not be less than 180mm, the strength grade of concrete should not be less than C20, the section area of the reinforcement calculation is determined by the structure of blast wall hole should not be Liudong. When the process pipelines and cables must pass through, the hole should not be greater than 200mm diameter, hole periphery should be configured to reinforcement, filling and compacting holes should be.
