Staggered distribution plate type composite missile shielding structure

Abstract

The invention belongs to the technical field of engineering protection and discloses a staggered distribution plate type steel-based composite missile shielding structure. The staggered distribution plate type steel-based composite missile shielding structure is of a plate type structure constituted in the mode that high-hardness core bodies are embedded into thin-wall box grid metal base bodies;a plurality of metal box grids on each layer are continuously arranged and distributed; the metal box grids on the upper layer and the lower layer are arranged and distributed in a staggered mode; thethin-wall metal box grids are overall of a vertical staggered distribution plate type structure formed by integral casting; the upper end faces of the thin-wall metal box grids on the upper layer areopen, and the lower end faces of the thin-wall metal box grids on the lower layer are open; each thin-wall metal box grid is internally provided with the corresponding high-hardness material servingas a missile-shielding structure filling core body; and the high-hardness materials and the staggered distribution metal box grids are bonded into a whole through adhesion agents to form the plate type composite structure. The staggered distribution plate type composite missile-shielding structure has the characteristics of being high in anti-impact force, good in impact toughness, excellent in performance, reliable, practical, convenient and rapid to construct, capable of resisting repeated strike, replaceable, easy to repair and the like.

[0002] The rapid improvement of precision-guided weapons in terms of projectile materials, hit accuracy, and destructive effects not only enhances their penetration capabilities, but also doubles their explosive destructive effects; how to improve the comprehensive protection capabilities of engineering facilities so that incoming weapons cannot hit Medium and deep drilling, impenetrable penetration, the development of advanced bullet-shielding technology, and the improvement of existing bullet-shielding structures have become an important means to enhance the effectiveness of engineering protection; most of the existing bullet-shielding materials or structures work by improving the bullet-shielding structure. The strength of the material itself increases the penetration resistance of the projectile or changes the ballistic trajectory of the penetrating projectile so that it is deflected and destroyed in order to reduce the effective penetration depth; for example, rubble concrete shield, steel fiber concrete shield, super high-strength concrete Bullet-shielding materials such as bullet-shielding layer and corundum block stone consolidated bullet-shielding layer, as well as bullet-shielding structural forms such as triangular hollow beam slab, concrete grid, steel fiber concrete containing rigid balls, steel plate-steel fiber concrete; the above-mentioned traditional shielding The elastic layer uses concrete or block stone as the matrix material. However, the concrete block stone material itself has defects such as small ratio of tensile and compressive strength, poor ductility, and brittle failure under strong impact loads, which greatly affects or hinders its further application. Problems such as difficulties in the production of bullet-shielding structures, high economic costs, and difficulty in on-site construction make it difficult to apply them to actual projects; therefore, how to seek better materials and more reasonable structural forms to develop new composite bullet-shielding structures , so that the bomb-shielding material and structural form can be organically unified, maximize its efficacy, and achieve the best cost-effectiveness ratio, which has become the era's requirement for strengthening the comprehensive protection capabilities of engineering facilities under high-tech warfare
