Abstract

FIELD: protective structures. SUBSTANCE: invention relates to firing structures, in particular to protective structures, namely to bulletproof protective armour domes, which will be used to protect people and equipment from small arms fire and fragments. The armour dome includes a monolithic reinforced concrete core and a reinforced concrete cover.

The first and second layers are connected to each other by flat frames. The cover has on the outer side a similar double-layer reinforcement with welded wire mesh, where the first and second layers consist of pairs of meshes connected and deployed towards each other, arranged horizontally, and on the inner side in the lower part of the cover, a third layer is made in a single-layer form, wherein the first and second layers are connected to each other by vertical flat frames. In the upper part of the reinforced concrete core and at the corners of the lower part of the cover, embedded parts are made for their mutual connection with each other, and the core and the cover are made of concrete of a class not lower than B60 with the addition of fibre.

Description

Field of technology to which the invention relates The invention relates to fire structures, in particular to protective structures, namely to bullet-proof protective armored caps, which will be used to protect people and equipment from small arms and shrapnel. State of the art An armored hood is a structure designed to protect people and equipment from small arms fire and shrapnel. It is typically used at guarded sites, checkpoints, and other locations requiring increased security. Depending on the material, armored caps are divided into steel, composite and reinforced concrete. Steel armored hoods offer advantages such as high bullet and fragment resistance, and provide all-round visibility. However, they can be bulky, expensive, and susceptible to corrosion. Composite armor caps offer several advantages, such as light weight, high strength, and corrosion resistance, making them effective protection against shaped-charge projectiles. However, their cost can be high, limiting their use to particularly vulnerable areas. Reinforced concrete armored caps offer a number of advantages, including high strength, fire resistance, corrosion resistance, and the ability to withstand climatic conditions and blast loads. However, they also have disadvantages, including heavy weight, poor sound insulation, and poor air permeability. In this case, the most advantageous option in terms of the ratio of advantages and disadvantages are reinforced concrete armored caps, since they provide maximum protection with minimal financial costs. Various armored cap designs are available, made of reinforced concrete with traditional reinforcement, including rebars arranged in standard patterns. These designs provide sufficient strength and rigidity under normal operating conditions. However, under increased loads or exposure to extreme factors (e.g., blast loads, impacts, vibrations), traditional armored caps may fail to provide the required level of reliability and durability. Solutions are also known that utilize additional measures to strengthen the reinforcement of reinforced concrete structures, such as the use of composite materials, increasing the cross-sectional area of the reinforcement, or employing special reinforcement arrangements. However, these methods are often associated with increased cost, manufacturing complexity, or limited manufacturability, limiting their widespread use. Therefore, there is a need to develop an armored cap made of reinforced concrete with a fundamentally improved reinforcement system, which would significantly improve the reliability and performance characteristics of the structure without significantly complicating the manufacturing technology or increasing the cost. A collapsible universal protective armored cap is known from the prior art, consisting of steel walls, viewing windows, a door that closes from the inside, characterized in that it contains a frame of transverse and longitudinal pipes fastened with bolts, wherein the walls are a double steel wall made of steel plates with interlayer insulation, and also contains viewing windows that open inward and steel plates located on the roof, welded to the top of the steel wall at an angle of 5° to 80°, and in the center between the said plates a mesh is stretched, secured to hooks welded to the ends of the plates (RU 195422, IPC E04H 9/10, published 04.06.2019). The disadvantage of the well-known utility model is the low technical characteristics of the structure. The closest in technical essence to the claimed invention is the precast monolithic reinforced concrete structure "Bronekolpak", which includes a monolithic reinforced concrete core and a reinforced concrete cover, wherein the reinforced concrete core is made in the form of a rectangular hollow structure without a lower and upper wall, is located vertically and has loopholes on the sides and an armored entrance door (Access mode: https://xn----btbehhn3akq1k.xn--p1ai/product/bronekolpak/, access date: 07/25/2025). The disadvantages of the known technical solution include insufficiently high technical characteristics, which is due to the fact that the armored cap is manufactured using exclusively high-strength concrete without additional reinforcement. Disclosure of invention The technical result of the claimed invention consists in improving the technical characteristics of the structure. The technical result is achieved due to the fact that the armored cap includes a monolithic reinforced concrete core and a reinforced concrete cover, wherein the reinforced concrete core is made in the form of a rectangular hollow structure without a lower and upper wall, located vertically and has loopholes and an armored entrance door on the sides, characterized in that the reinforced concrete core has a two-layer reinforcement with welded reinforcement meshes on the inner and outer sides along the entire perimeter, which is meshes connected in pairs and unfolded towards each other, located verti
