ANTI-RADIATION SHELTER Russian patent published in 2018 - IPC E04H9/04 

FIELD: machine building.

SUBSTANCE: invention relates to equipment for preventing earthquake consequences. This is achieved by the fact that a shelter containing a framework, an airlock, places for accommodation of evacuees, a filter-ventilation device, lavatory and water and food supplies, is equipped with a modular prefabricated earthquake-proof structure, containing a system of blocks and connecting elements connected in a single structure, it consists of elements made in the form of blocks, some of which are made in the form of a rectangular parallelepiped with grooves formed on four faces of the parallelepiped in the plane of its symmetry, while the grooves are formed with cylindrical holes to match the outer diameter of the cylindrical body of the connecting element, and the other blocks are interfaced with the first ones and are made in the form of a rectangular parallelepiped with spikes formed on four faces of the parallelepiped, while the grooves are formed with cylindrical holes to match the outer diameter of the cylindrical body of the connecting element, wherein the surfaces of the grooves and studs are equidistant, congruent and equal in size and are connected to a modular prefabricated structure by means of connecting elements.

EFFECT: technical result – reduction of the time of construction of the shelter due to the framing of the frame with a modular closed structure.
