1) The explosion-proof wall should be made of non-combustible materials, and should not be used as a load-bearing wall, and its fire resistance limit should not be less than 4h; 2) The explosion-proof wall can be reinforced brick wall. When there are more production personnel or more expensive equipment in adjacent rooms, it is advisable to use cast-in-place reinforced concrete walls;
3) The thickness of the reinforced brick wall should be determined by the structural calculation, but it should not be less than 240mm, the brick strength should not be lower, and the mortar strength should not be less than m 5. Construct fit.
Structural reinforcement: 3 6-10 horizontal steel bars are configured every 500mm along the height of the wall, and their two ends should be tied or welded with the reinforced concrete frame or row frame columns. When the length and height of the brick wall are greater than 6m, reinforced concrete intermediate columns and beams should be set up, and reinforcement should be arranged according to the structure.
The concrete strength grade should not be lower than C15, and its end should be connected with the roof beams and frames, row frame columns.

The explosion-proof wall is composed of layers of structure, the middle layer of the explosion-proof wall is made of fiber cement board, the surface structure is galvanized steel plate, there is a certain distance between the surface steel plates, and then a round hole is made on the panel, and the steel plate in the hole is jagged when punching, and then it is pressed all the way to the fiber cement layer in the middle, and then pressed with pressure.
Because there is a thick layer of steel plate in the middle, when an accident occurs, it can enhance the impact resistance of the wall. The structure of the explosion-proof wall system is flexible and changeable, using a honeycomb structure, which can be well connected with other rigid structures, and only needs to punch holes during construction, does not need other complex processes, is simple and convenient to operate, and the surface is galvanized steel material, which can enhance the impact resistance.

The definition of anti-riot strength refers to the wall that has the ability to resist the shock wave and can limit the destructive effect of the first to a certain range.
-
It is only used in factories and warehouses with less substances.
Structural requirements for rolling fronts: column spacing should not be greater than 6m, and the large volume should be clear at 6m plus structural columns.
The height of the brick wall is not more than 6m, and the height is greater than 6m plus the beam; The thickness of the brick wall is not less than 240mm; The brick grade should not be lower, and the mortar grade should not be lower than m5; Each vertical height should not be less than the structural reinforcement; The two ends are embedded and welded with steel concrete columns or tied with No. 24 galvanized iron wire.
Brick marking: according to the compressive and flexural strength, it is divided into: MU four grades.
Mortar number: Compressive strength of the cube in Genju Bizen.
Divided into: six levels.

Summary. Hello dear, happy to answer your <>
The general principles of explosion-proof design include the following:1Cut less combustible items:
Reduce the use of flammable and explosive materials, replace combustible materials with non-combustible and non-combustible materials, and reduce the density and occupied area of combustible materials. 2.Control of oxygen concentration:
Reduce the concentration of oxygen in the air, avoid the air and combustible gas from reaching the flammable limit, limit the flow of oxygen or take measures to prevent the entry of the atmosphere. 3.Stop the chain reaction:
Chemical chain reactions are prevented by reducing the temperature of combustibles, increasing the concentration of inert gases, and increasing surface reaction moderators. 4.Control Wave Propagation:
Take isolation and protective measures to control the spread of ** waves<>

The general principles of explosion-proof design include the following points:1Cut less combustible items:

The following are related extensions, I hope it will be helpful to you before <>
5.Set up safety exhaust devices: Set up explosion-proof doors, explosion-proof rupture discs and other safety devices to ensure that the pressure is released in a timely and effective manner.
6.Regular inspection and maintenance: Regularly excavate bridges to inspect and maintain facilities, and find and solve potential hidden dangers in a timely manner.
In addition to the above general principles, it is necessary to formulate corresponding explosion-proof design plans according to the characteristics <>of different industries and different places, combined with professional knowledge and practical experience
1. The three-dimensional parking lot site should be flat, solid and non-skid, and should meet the drainage requirements and meet the requirements of urban traffic, fire prevention and environmental protection. Underground car parking garages should avoid areas where the groundwater level is too high or the geological structure is particularly complex and undesirable geological areas, and avoid the main pipes and lines of underground public facilities. >>>More
