Blockage and air ventilation type explosion-proof and fireproof plate

Abstract

The invention provides a blockage and air ventilation type explosion-proof and fireproof plate, and belongs to the field of disaster prevention of projects. The blockage and air ventilation type explosion-proof and fireproof plate is of a rectangular structure, and is characterized in that the inner surface layer and the outer surface layer are respectively a first pressure-relief vibration-proofand fireproof plate layer and a second pressure-relief vibration-proof and fireproof plate layer; vertical end reinforcing transverse ribs are arranged at both ends, and vertical middle reinforcing transverse ribs are uniformly distributed in the middle position; two rows of middle heat-blockage fireproof cavities are uniformly distributed in the middle position. The blockage and air ventilation type explosion-proof and fireproof plate has the beneficial effects that the fireproof property is good, the stress property is good, the installation is convenient, the replacement is easy, and the installation is quick, simple and convenient; the surface layer is provided with an obvious pressure-relief vibration-proof port, a fire blockage layer in the middle position has obvious buffer and fireblockage double functions, the explosion-proof and fireproof properties are obviously improved, and the personal casualty and the economic loss are effectively reduced when a fire accident occurs onan underground structure.

Description

technical field [0001] The invention belongs to the field of engineering disaster prevention, and in particular relates to an explosion-proof and fire-proof board with partition and ventilation. Background technique [0002] In recent years, underground structures have developed rapidly in our country, and many subways and underground complexes have been built one after another. However, the fire prevention of underground structures has always been an insurmountable difficulty for underground structures. [0003] At present, fire retardant coatings are widely used, but the thickness and thermal conductivity of fire retardant coatings are limited, so they cannot play an effective role at all. [0004] In addition, fires in underground spaces are often accompanied by explosions. Due to the narrow space, the energy cannot be released, which doubles the destructive power of the explosion, so special attention should be paid. SUMMARY OF THE INVENTION [0005] In order to solve...
