Overview of Explosion-Proof Wall for Server Room

Section 1: Definition of Explosion-Proof Wall in Equipment Room

Explosion-proof walls for server rooms are designed to protect the server room from the impact and pressure of explosions, ensuring the safety of personnel and equipment inside.

Section II: Common Types

·         Blast-resistant steel plate wall

·         Lightweight explosion-proof wall

III. Selection Key Points

1.     Available in insulated and non-insulated types, the insulated explosion-proof wall is filled with rock wool in the middle of the frame, with a fire resistance limit up to 4h。

2.     The dimensions of the cold-formed equal-channel shaped steel used for the frame are determined based on the required explosion-proof pressure values and the height of the walls (refer to the pressure values in the assembly drawings). 1400kPa）。

Section 4: Design Purpose

1.     Buildings must remain standing, ensuring the safety of personnel inside, and guaranteeing that critical control equipment within the buildings can continue to operate for a period of time.

2.     Meets rescue requirements, maintains indoor life environments, sets up passages and related measures.

V. Structural Arrangement

1.     Explosion-proof shear walls and frame structures: Explosion-proof shear walls are decoupled from frame columns. 50mmThe explosion horizontal force is borne by the blast-resistant shear wall, while the frame structure only withstands vertical loads. This is a type of structural scheme that is currently widely used.

6. Materials and Structure

1 .The explosion-proof wall is composed of steel studs, fiber-cement composite steel plates, and rock wool. 

2.     Fiber-cement composite steel plate is composed of two upper and lower plates that are perforated.0.5mmThick galvanized steel plate is strongly extruded onto8.5mmComposite fire-resistant boards constructed on thick fiber cement, with the fiber cement layer sandwiched between two steel plates, serves as an energy-absorbing element.

Section 7: Selection Key Points

1.Explosion-proof walls are available in two types: non-insulating and insulating. Insulating types feature fiber-cement composite steel plates on both sides of the metal frame, with rock wool filled in the middle. The fire resistance limit of insulating explosion-proof walls can reach4h。

2.After selecting the manufacturer, the explosion-proof wall requires a secondary design by the manufacturer. The steel rebars of the explosion-proof wall are made of cold-bent equal channel steel, with the size of the cold-bent equal channel steel determined by the structural calculation based on the explosion-proof pressure requirements and the wall height.

3.This image album introduces two types of rib arrangements for your reference selection. The explosion-resistant pressure value can reach1400kPa。

4.The detailed drawings of the fiber-cement composite steel plate explosion-proof wall construction in this collection are provided as an insulated type example only. The construction method for non-insulated explosion-proof walls is essentially the same and can be referenced for use.
