Explosion-proof wall design requirements

1. Plan explosion-proof walls to meet the following requirements:

(1) Non-burning materials should be used for Explosion-proof walls and should not be used as bearing walls. The fire resistance limit should not be less than 4 H. (2) Reinforced Brick walls can be used for Explosion-proof walls. Cast-in-place reinforced concrete walls should be used when there are many persons or equipment in adjacent rooms is more valuable;

(3) The thickness of the Reinforced Brick wall should be determined by the structure calculation, but it should not be less than 240mm, the brick strength should not be lower than mu7.5, And the mortar strength should not be less than M 5. Configuration Construction

Structural Reinforcement: the structural reinforcement is equipped with a 3-500mm long horizontal steel bar at intervals of along the height of the Wall Body. The two ends of the steel reinforced concrete structure or rack-mounting column should be buried, inserted, bundled, or welded. When the length and height of the brick wall are greater than 6 m, the reinforced concrete center column and the crossbar should be set and the reinforcement should be constructed. The concrete strength grade should not be lower than that of C15, and its end should be connected with the roof beam, frame and layout column;

(4) the reinforced concrete explosion-proof wall thickness should not be less than 180mm, the concrete strength grade should not be less than C20, and the steel section area should be determined by the structure calculation;

(5) do not leave holes in the explosion-proof wall. When it is necessary to wear a process pipe, cable, etc., the hole should not be greater than 200mm, the surrounding area of the hole should be equipped with Reinforced Steel, the hole should be filled with tight sealing.
