EARTHQUAKEPROOF BUILDING WITH WALLS OF BLOCK CONSTRUCTION Russian patent published in 2018 - IPC E04H9/02 

FIELD: construction.

SUBSTANCE: invention relates to construction, namely to repair, recovery or erection of aseismic buildings and structures. This is achieved by the fact that in an earthquake-proof building with walls of block construction containing a vibration-insulated foundation, horizontal and vertical bearing structures with a vibration isolation system, internal partitions, the roof of the building, as well as door and window openings with reinforcement, the base load-bearing slabs are provided in the places of their fastening to the bearing walls of the building by a system of spatial vibration isolation, consisting of horizontally located vibration isolators, perceiving vertical static and dynamic loads, wherein floor in rooms is made on elastic base and comprises mounting plate, made of reinforced vibration damping concrete material, which is installed on the base plate of the interfloor overlapping with the cavities through the layers of the vibration damping material and the waterproofing material with the clearance relative to the bearing walls of the production premise, wherein the cavities of the base plate are filled with a vibration damping material, for example a foamed polymer, the elastic base of the floor is made of a rigid porous vibration-absorbing material, for example an elastomer, or a polyurethane with a degree of porosity in the range of optimum values: 30÷45 %, in the cavities of the base plate are placed shock-absorbing inserts, made in the form of a cylindrical damping element, the inner cavity of which is filled with vibration damping material, and to the ends of which rigidly attached flat elastic stops, whose diameter is 5÷10 % less than the diameter of the cavities of the base plate, and the length of the cylindrical damping element by 5÷10 % less than the length of cavities of the base plate, after installation of the vibrating damper, the elastic stops are embedded in the foam polymer flush with the end faces of the base plate.

EFFECT: reinforcement of buildings or installations, reducing their vulnerability under action of wind loads and earthquakes, improved seismic safety, durability and service life.
