PROTECTIVE FORTIFICATION Russian patent published in 2025 - IPC E04H9/12 

FIELD: construction.

SUBSTANCE: invention relates to the field of construction, namely to the prefabricated, and, if necessary, collapsible, field protective structures of the Ministry of defence for the protection of personnel and equipment from the effects of air attacks, including unmanned aerial vehicles (UAV), and enemy artillery fire, as well as for shelter from atmospheric effects and bad weather, and can be used in construction of trenches, erected using engineering equipment in areas of concentration of troops. Protective fortification arranged in trench comprises side walls and roof-coating made of panels, wall and roof-coating panels, respectively. Side walls include waterproofing, which covers the side slopes of the trench, and wall panels from the profiled flooring, wherein in the transverse direction the profiled flooring of each wall panel is fastened by stiffeners placed along the entire length of the structure at a distance from each other, which ensures the perception of the design loads of the structure, wherein each stiffening rib is made in the form of a spatial truss, and the lower and upper ends of the stiffening ribs of the opposite side walls of the structure are interconnected by spacers, forming a stiffness arch and a base, on which a roof covering panel is laid, made of a profiled flooring, on top of which there are sheets of composite material and a power flooring assembled from universal modular elements, profile of each of which in cross-section is an open trapezoid, the upper small base of which is a base-shelf, and the lower larger base is made open, wherein the load-bearing flooring of the coating is laid on top of the roof-coating panel with support on the ground, and a composite woven cloth is laid on top of the load-bearing flooring of the coating of the structure and soil is filled.

EFFECT: production of prefabricated elements of prefabricated, and, if necessary, collapsible, protective fortification structure, which can be easily delivered to the installation site.
