FIELD: military construction.SUBSTANCE: invention relates to small capital fortification structures for protecting people and equipment from small arms and shrapnel. The permanent fire point includes four monolithic reinforced concrete walls that form a rectangular hollow structure and a roof slab. The walls are connected to each other and to the roof slab using mounting embedded parts. Three walls comprise loopholes, and the fourth wall comprises an armoured entrance door. The walls have a two-layer reinforcement on the inside and outside with welded reinforcement meshes, which are meshes connected in pairs and turned towards each other, located vertically and offset by 0.5 steps relative to each other. Between the inner and outer sides of the wall reinforcement there is a shortened additional mesh, which is connected to the outer side of the wall reinforcement by a flat frame. The inner and outer sides of the wall reinforcement are also connected to each other by a flat frame. The roof slab has a similar two-layer reinforcement with welded reinforcement mesh on the outside. The first and second layers are meshes connected in pairs and facing each other, located horizontally. On the inside, at the bottom of the lid, the third layer is made in a single layer. The first and second layers are connected to each other by vertical flat frames. The walls and roof slab are made of concrete of at least class B 60 with the addition of fiber.EFFECT: increased strength, durability and reliability through enhanced reinforcement of the structure.17 cl, 6 dwg
