Lightweight high-explosion-resistant unit plate and protection product thereof

Abstract

The invention discloses a lightweight high-explosion-resistant unit plate and a protection product thereof. The unit plate comprises an outer metal plate layer, a middle metal plate layer, an inner metal plate layer, an energy absorption layer and a foam metal plate layer which are arranged in parallel. The energy absorption layer comprises a plurality of energy absorption sub-layers, and each energy absorption sub-layer comprises a plurality of energy absorption pipes which are arranged in parallel. The energy absorption pipes of every two adjacent energy absorption sub-layers are perpendicular to each other. The energy absorption layer is arranged between the outer metal plate layer and the middle metal plate layer, and the foam metal plate layer is arranged between the middle metal plate layer and the inner metal plate layer. The outer surfaces of the outer metal plate layer, the middle metal plate layer, the inner metal plate layer, the energy absorption pipes and the foam metal plate layer are all sprayed with explosion-resistant paint. The lightweight high-explosion-resistant unit plate has the advantages of being high in resistance, small in weight and convenient to transport, and is suitable for manufacturing explosion-resistant doors, explosion-resistant walls, explosion-resistant roofs and wall column protection plates.

Description

Technical field[0001]The present invention relates to a high anti-proof unit plate, in particular a lightweight high-explosion-proof unit plate, belonging to the technical field of protective structures.Background technique[0002]There are many types of bulletproof anti-explosive composite structures, commonly highly high-strength concrete, steel structures or polymer high-strength fiberboard structures. Although these bulletproof anti-proof composite structures also have a certain bulletproof explosion-proof effect, there are all bullet-proof anti-explosion resistance, large weight (mainly refers to steel explosion-proof bulletproof structure or wall), high cost, and relatively durability Poor, etc., and use ordinary engineering materials panels to build the building, the outer walls are not only required for the thickness or size of the sheet, but also the problem of large construction materials, and the anti-proof explosive effect is very low. Therefore, in the army, public securi...

AI Technical Summary

Problems solved by technology

The bulletproof and explosion-proof composite structure in the prior art contains materials such as concrete or foam concrete, which has low resistance, easy deformation and heavy weight

Transportation and installation are inconvenient. Due to the huge size of the door panels, the requirements for the foundation bearing capacity are high. In order to prevent foundation settlement, especially uneven settlement, it increases the difficulty of foundation construction in some weak soil areas, prolongs the construction period, and makes the ground protection project The location of the site is subject to certain restrictions

Once the door panel is under the action of high-intensity shock waves, the door opening and device are easily deformed under the weight of the door panel and the impact of the shock wave, resulting in the door being unable to open; normal opening and maintenance

According to the damage phenomenon and analysis of the explosion-proof door in the explosion test in the tunnel, the destructive effect of the explosion-proof door is the result of the combined action of fragments and shock waves. It is impossible for the single action of fragments and shock waves to cause such serious damage. It is necessary to consider the deformation and damage of the fragments penetrating the explosion-proof door and the explosion-proof door under the action of the shock wave alone, and more attention should be paid to the combined damage of the fragments and the shock wave to the explosion-proof door. Under the dual action of the fragments and the shock wave, the bulk material will cause secondary Splashes will cause a certain degree of damage to objects and personnel inside the protective door, etc.
