Fiber-Reinforced Cement Board Blast-Relief Wall System — Safe, Lightweight, Controlled Pressure Release

Fiber-Reinforced Cement Board Explosion-Venting Wall System — A Safe, Lightweight, and Controllable Pressure-Relief Choice

Promoting the upgrade of indoor explosion-protection building standards and building a controllable pressure-relief safety line. With the wide application of hazardous chemicals in research, manufacturing, and storage, the potential explosion risk in indoor environments places higher demands on building construction. Developed and promoted by Shanghai Tengxi Construction 14J938 Engineering Co., Ltd. (national atlas participating unit), the "Fiber-Reinforced Cement Board Explosion-Venting Wall System" provides an indoor explosion-protection solution for hazardous locations that balances structural integrity with directional pressure-relief functionality.

GB 5001614J938 This system is strictly designed in accordance with the "Code for Fire Protection Design of Buildings" and national atlas requirements, combined with pressure-relief area calculation principles. It is widely applicable to small and medium indoor spaces such as laboratories, chemical storage rooms, and battery storage areas, providing a safe, standardized, and implementable pressure-relief construction system for high-risk environments.

• Scientifically composed system with superior explosion-venting performance

The fiber-reinforced cement board explosion-venting wall consists of a three-layer structure: fiber-reinforced cement board, light steel keel frame, and rock wool infill. It has the following core advantages:

• Standardized installation process to ensure system integrity and construction quality

To ensure the explosion-venting wall functions properly under extreme conditions, Shanghai Tengxi has established a rigorous, reproducible installation procedure:

、Panel installation key points:

• Interior and exterior wall panels are fixed to both sides of the light steel keel, with rock wool filled in between;
• Panels are fixed with screws at specified spacing;
• The keel is anchored to the structure with expansion bolts;
• Panel faces must be staggered and expansion joints reserved; gaps are treated with flexible crack-resistant putty to ensure airtightness and structural integrity;
• Keel structure should be reinforced at openings and wall-penetrating pipes to improve local stability.

、Finish layer requirements:

• After the panel surface is clean and dry, treat nail holes and joints, apply reinforcing mesh and skim crack-resistant putty;
• Finish materials should be lightweight materials that will automatically detach or flexibly release under explosive action;
• Recommended finish options include: natural stone paint, elastic coatings, perforated acoustic panels, lightweight cladding panels, etc.;
• It is strictly forbidden to fix finishes using rigid connections, to avoid inhibiting the venting function;
• Upon completion, verify that the venting direction is reasonably set to ensure the system has the intended pressure-relief path.
• Construction precautions to ensure structural safety and compliance

20 kPa·All panels must be supplied by qualified manufacturers and provide explosion-venting performance test reports not lower than the design pressure;

• Panel installation must be secure and flat; loosening, buckling, or detachment is strictly prohibited;

• Finish construction should comply with the "Code for Acceptance of Construction Quality of Building Decoration and Refurbishment Works" and must not have hollowing, cracks, or other quality defects;

• The overall structure must ensure that under explosion shock, the venting wall can smoothly release pressure, and related components possess a safe separation mechani sm to avoid creating secondary sources of harm.

• Professional assurance from standards development and engineering experience
