SHELTER Russian patent published in 2018 - IPC E04H9/02 

FIELD: construction.

SUBSTANCE: invention relates to a technique for preventing earthquake consequences. Proposed shelter contains the main room in the form of an earthquake-proof structure, which has interconnected walls, overlapping and base made of interconnected concrete reinforced panels, entrance equipped with a sluice, and life support system, the main room is equipped with a block quick-erect earthquake-proof construction containing a system of blocks and connecting elements connected in a single structure, wherein it consists of elements made in the form of blocks, one of which is made in the form of a rectangular parallelepiped with grooves made on four faces of the parallelepiped, in the plane of its symmetry, wherein the grooves are made 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 made on four faces of the parallelepiped, spikes being provided with cylindrical holes for the outer diameter of the cylindrical body of the connecting member, wherein the surfaces of the grooves and studs are equidistant, congruent and equal in size and are connected to a block prefabricated structure by means of connecting elements, wherein the connecting element for the blocks of the seismic resistant structure consists of an elastic cylindrical body with mounting discs fixed at its ends, wherein the 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 to their end part, on which the elements for threading the sleeves into a single cylindrical body are made, and is made of an elastic material, for example, from an elastic spring steel, the cavity of which is filled with a damping material, for example a shock-absorbing mastic of the "VD-17" type, and within the cylindrical body of the connecting element an elastic core is arranged in axial alignment and coaxially to the connecting element, along the axis of the elastic core damping disks are rigidly fixed along the entire length of the cavity, wherein the extreme disks are fixed to the mounting discs of the shock-absorbing material, while there are helical coil springs in the cavities between the disks. At least three resilient rods are arranged coaxially to the elastic core of the connecting element, inside the resilient cylindrical body, their rigidity is less than the rigidity of the elastic core, they are fixed in the damping disks in such a way that their external surfaces touch the inner surfaces of the helical coil springs.

EFFECT: reduction of the time of construction of the shelter due to the framing of the frame with a block closed structure.
