SHELTER WITH PROTECTION FROM ELECTROMAGNETIC RADIATION Russian patent published in 2018 - IPC E04H9/02 

FIELD: construction.

SUBSTANCE: invention relates to equipment for preventing earthquake consequences. In a shelter with protection from electromagnetic radiation, containing a frame, a sluice, places for accommodation of evacuees, a filter-ventilation device, a toilet and water and food supplies, while it is equipped with a block quick-erectable earthquake-proof construction containing a system of blocks and connecting elements, one of the blocks is made in the form of a rectangular parallelepiped with grooves made on four faces of the parallelepiped, in the plane of its symmetry, grooves are formed with cylindrical holes for 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, executed on four faces of the parallelepiped, spikes being provided with cylindrical holes for the outer diameter of the cylindrical body of the connecting element, surfaces of the grooves and studs are equidistant, congruent and equal in number and are joined in a block, quick-build structure by means of connecting elements, connecting element for the blocks of the seismic resistant structure consists of an elastic cylindrical body, with mounting discs fixed to its ends, cavity of the cylindrical body is filled with a damping material and the body is made of two flanged, oppositely disposed and coaxial cylindrical threaded sleeves with fixed mounting discs fixed to their end part, on which the elements for threading the bushings into a single cylindrical body are made and is made of an elastic material, for example spring steel, the cavity of which is filled with a damping material, for example a VD-17 vibro-damping mastic, block quick-erectable earthquake-resistant structure contains, as lining, elements of a portable radiation shielding, each of which elements comprises a protective shell, a matrix with a filler, a reinforcing mesh, at the same time, rectangular sheets with holes are installed along the perimeter of the protective shell, attached to the protective polymeric material and providing the possibility of fixing and assembling protective screens on the walls of a block, prefabricated closed structure of the shelter, radiation protection part in the form of a protective shell of the portable radiation shield is made of a composite radio-absorbing material containing a ferrite-based powder filler and a polymer binder, material containing a mixture of barium hexagonal ferrite doped with scandium ions with a dispersion of 5 to 50 mcm with the addition of carbon nanotubes is selected as the powder filler, with the following component content, wt. %: barium hexagonal ferrite, doped with scandium ions, 58.80÷69.93; carbon nanotubes 0.1÷2; polymer binder 29.40÷39.96.

EFFECT: invention relates to the technique for preventing the effects of earthquakes and is aimed at reducing the time of construction of a shelter.
