Explosion relief wall of warehouse
Explosion relief wall
1. Explosion relief wall: it is a wall that has the ability to release explosion shock waves and can limit the destructive effect of explosion within a certain range.
2. 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.
3. The pressure relief part of the light pressure relief wall (excluding structural columns and wall beams) is composed of light materials. When an accident occurs inside the building, it has pressure relief effect. The purpose of pressure relief is to ensure the safety of the main structure of the building.
4. The light and fragile wall is also composed of light and fragile materials (excluding structural columns and wall beams). When an accident occurs inside the building, it not only has the pressure relief effect, but also breaks into small pieces to reduce the impact on the outside of the building.
5. Scope of application of explosion relief wall
(1) It is applicable to dangerous production workshops requiring explosion venting.
(2) Light pressure relief walls are used for production workshops with dust explosion and gas explosion hazards,
(3) Light and fragile walls shall be used for workshops with high energy explosion hazard.
(4) Explosion relief walls are widely used in buildings, such as commercial buildings, industrial, petrochemical, transportation facilities, gas stations, large warehouse fire prevention areas, substations and generator rooms, oil storage, chemical raw material storage areas, chemical plant workshop production areas, pharmaceutical plants, wineries, high-tech electronic plant control rooms, high-value and important document databases.
6. Explosion relief wall classification
(1) Light pressure relief wall is divided into rock wool sandwich color steel plate wall and single-layer profiled steel sheet composite insulation wall.
(2) The light and fragile wall is divided into three types: fiber reinforced cement board wall, expansive stone light board wall and foam concrete composite wall board.
