ASEISMIC BUILDING 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. In the earthquake-proof building, which contains the vibration-insulated foundation, horizontal and vertical bearing structures with the vibration isolation system, internal partitions, the roof of the building, as well as door and window openings with reinforcement, base load-bearing floor slabs are equipped in the places of their fixation to the bearing walls of the building with a system of spatial vibration isolation consisting of horizontally located vibration isolators that receive vertical static and dynamic loads, as well as vertically located vibration isolators that perceive horizontal static and dynamic loads, while the floor in the rooms is made on the elastic base and contains the installation plate, which is made of concrete that is reinforced with vibration damping 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, the cavities of the base plate are filled with the vibration dampening material, for example a foamed polymer, and each of the vibration isolators consists of rigidly interconnected rubber plates: the upper and lower ones, in which through holes are made, located on the surface of the vibration isolator in staggered order, and in the form of vibration isolators are made square or rectangular, and their lateral faces are made in the form of curved surfaces of the n-th order, providing for the equal frequency of the vibration isolation system as a whole, while the openings have in the cross-section the shape, which provides for equal frequency of the vibration isolator, each of the vibration isolators is equipped with vibro-damping inserts, which are located in the openings of each of the vibration isolators and made in the form of a cylindrical damping element, to the ends of which rigid elastic supports are rigidly attached, and the inner cavity is filled with the layer of the vibration damping material, for example sand, while the density of the vibration damping layer is less than the density of the outer cylindrical shell of the damping element.

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