PROTECTION OF STRUCTURES Russian patent published in 2025 - IPC E04H9/00 

FIELD: construction.

SUBSTANCE: invention relates to the field of construction, in particular to the layered explosion-proof structures intended for the protection of various structures and special-purpose objects from the impact action of the explosive, and can be used in engineering equipment for protection of various structures and ground structures subjected to high-intensity pulse loads from destructive consequences of accidental or undesirable explosions, for example, in case of accidents, or catastrophes, or from falling of aircraft, or other high-speed bodies. Protection of structures comprises a protective structure in the form of a frame and a multilayer protective screen with a mesh base, placed at a distance from the outer perimeter and above the structure in need of protection. Frame protective structure is made in the form of separately standing supports, which are placed along the perimeter of the protected structure and fixed on the foundation, and in the form of spacer rings, external and internal, which are placed between the supports above the protected structure and connected to them, and the tops of the separate supports protruding above the protected structure are connected to each other by a bearing span rod structure, which is connected to the inner spacer ring and supports it in a suspended position, wherein the supports are pivotally connected to the body of the protected structure by means of braces, and the protective screen placed above the structure in need of protection is made in the form of at least two grids, one of which is installed on the outer side of the protected structure above the spacer rings, and the second and subsequent grids are placed directly above the protected structure under the spacer rings, besides, the protective screen is fixed on the suspended bearing span rod structure.

EFFECT: there is created an industrially manufactured pre-fabricated, and if necessary collapsible, protection of structures, which is easily delivered to the place of installation, having a high degree of efficiency of protective properties of structures against dynamic action.
