RU2335610C1 - Method of safety of above-ground buildings or structures and protective domed structure - Google Patents

Abstract

FIELD: construction.

SUBSTANCE: methods of safety of above-ground buildings or structures and a protective domed structure are based on using a protective cover erected over the protected building or structure. The protective structure includes an external layer of the bands of the conducting material interwoven in a netted base, a layer of faceplates, a layer of lead or paraffin and a layer of metal foil. The space between the protective cover and the protected building or structure is filled with foamed material, for example a hard oil product.

EFFECT: protection of buildings and structures from adverse factors of the fragmentation demolition weapon; penetrating radiation; electromagnetic radiation; radiation exposure; chemical and biological action, and improved target detection hardness.

Description

The proposed technical solution relates to the field of construction and is intended to protect buildings or structures in various emergency situations, for example, from the effects of explosions in accidents and disasters, or from the fall of aircraft, or other high-speed bodies, etc.

From patents RU 2155844 and RU 2186916, methods of protection against external impacts of objects with a nuclear power plant are known, which can be used to protect almost any ground-based buildings or structures. Known methods of protecting surface buildings or structures include the erection of a protective shell formed by a metal structure over the protected building or structure. When implementing the methods, a structure is being erected over the protected object with a nuclear power plant, including supporting structures and protective barriers erected over the protected object. Protective barriers are made in the form of nets fixed on supporting structures made of ropes made of elastic material. The method of protecting ground objects, known from patent RU 2186916, is selected as the closest analogue of the proposed method of protecting ground buildings or structures.

From the patent RU 2100549 a protective dome structure is known, which is intended to protect various ground objects. The protective dome structure includes a shell formed by a metal structure on which the protective material is located. The shell of the protective dome structure is formed by a lattice metal structure of tubular rods on which a protective sheet material is fixed. A lattice metal structure is erected above the protected building or structure. A mesh of plastic wire is stretched over the tubular rods, on which a layer of compliant material is laid, coated on top with a protective film. The protective dome structure known from the patent RU 2100549 is selected as the closest analogue of the proposed protective dome structure.

Technical solutions known from the patents RU 2155844, RU 2186916 and RU 2100549 are intended to protect buildings and structures only from the effects of a shock wave. That is, the well-known building construction will not provide protection of buildings and structures from other damaging factors that arise during various emergency situations (damaging factors of high-explosive fragmentation weapons, penetrating radiation, electromagnetic radiation, radiation, chemical and biological infection, etc.).

The proposed technical solution will eliminate this drawback, which will increase the reliability of protection for various types of buildings and structures, as well as increase the security of the object from detection using optical-visual, radar and infrared reconnaissance.

The proposed technical result is achieved by the fact that the proposed method of protecting ground buildings or structures using a protective dome structure.

A method of protecting ground buildings or structures includes erecting a protective shell formed by a protective structure over the protected building or structure. A protective structure erected over a protected building or structure is made of protective plates. On the outer surface of the protective plates, a layer of strips of electrically conductive material woven into the mesh base is applied. A layer of lead or paraffin is applied to the inner surface of the protective plates, onto which a layer of metal foil is then applied. The resulting space between the protective structure and the building or structure to be protected is filled with foam material, for example, solid oil.

The protective dome structure includes a shell formed by a protective structure on which the protective material is located. The protective structure is a combination of protective plates. On the outer surface of the protective structure is a layer of strips of electrically conductive material woven into the mesh base. A layer of lead or paraffin and a layer of metal foil are sequentially arranged on the inner surface of the protective structure. The protective dome structure is located above the building or structure in need of protection. The space between the building or structure and the containment is filled with foam, such as solid petroleum products.

The proposed technical solution is illustrated by drawings:

figure 1 is an initial view of a building in need of protection;

figure 2 - metal frame erected above the building;

figure 3 - a protective shell erected above the building;

4 is a structural diagram of a protective shell.

A protective dome structure is being erected above the protected building or structure. The protective dome structure is a protective shell consisting of a set of elements (modules). The basis of a structure made of a set of modules is a structure that can be made in the form of a frame (metal or made of composite polymer materials based on hydrocarbon), which is then sheathed with protective plates. On the outer surface of the protective plates, a layer of camouflage garlands woven into the mesh base is made of cut and twisted strips of a three-layer electrically conductive material (for example, a layer of camouflage type MKT-3LR). The outer layer of the protective shell of the structure provides protection from optical-visual and radar reconnaissance. The basis of the protective shell of the dome structure is a protective structure, which is a set of protective plates made of metal or of composite polymeric materials based on hydrocarbon. The layer of protective plates is designed to protect the object from the shock wave arising from the explosion and the damaging factors of high-explosive fragmentation weapons. When using metal, it is preferable to use steel plates with a minimum thickness of at least 2 mm. On the inner side of the protective plates, a layer of lead or paraffin and a layer of metal foil (for example, TOP-type coatings) are arranged in series. A layer that can be made of either lead or paraffin is designed to protect against radioactive radiation. The layer of metal foil is designed to reflect the internal infrared radiation coming from the protected building or structure, and provides protection of the object from infrared reconnaissance.

The space between the protective shell and the building or structure is filled with foam material, hardening after filling and providing sealing of the object. The foam material may be any homogeneous material or a mixture of materials. It is possible to use solid petroleum products as materials, such as, for example, kumatik and / or paraffin.

Thus, the proposed technical solution will protect buildings and structures from almost any damaging factors that arise in emergency situations (shock wave, damaging factors of high-explosive fragmentation weapons, penetrating radiation, electromagnetic radiation, radiation, chemical and biological contamination), and ensure compliance with the requirements safety in the protection of buildings and structures, which will increase the reliability of protection for various types of buildings and structures.
