SEISMIC-RESISTANT LOW NOISE BUILDING Russian patent published in 2017 - IPC E04H9/02 E04B1/98 E04B1/86 

FIELD: construction.

SUBSTANCE: in seismic-resistant building containing the vibration-isolated foundation, the horizontal and vertical bearing structures with the vibration isolation system, the internal partitions, the building roof, as well as the door and window openings with reinforcement; the base bearing floor slabs in the points of their attachment to the bearing building walls are equipped with the spatial vibration isolation system consisting of horizontally arranged vibration isolators perceiving vertical static and dynamic loads, as well as vertically arranged vibration isolators perceiving horizontal static and dynamic loads. The floor in the premises is made on an elastic foundation and includes a mounting plate made of concrete reinforced with vibration damping material, which is mounted on the base intermediate floor slab with cavities through the layers of the vibration damping material and the waterproofing material with the gap relative to the bearing walls of an industrial premise. The base slab cavities are filled with a vibration damping material, such as foamed polymer, and each of the vibration isolators comprises the rigidly interlinked rubber plates, the upper and the lower ones, in which through openings are made, arranged on the isolator surface in the staggered order; the vibration isolators are made of a square or a rectangular shape, and their side faces are made as curved surfaces of the n-th order, ensuring the equifrequency of the vibration isolation system in general. The openings in the cross-section have the shape ensuring the vibration isolator equifrequency. Each of the vibration isolators is provided with vibration-damping inserts placed in the openings of each vibration isolator and configured as a cylindrical damping member, to the ends of which the planar resilient stops are rigidly connected, and the inner cavity is filled with a layer of vibration damping material, e.g. sand. The vibration damping layer density is less than the density of the outer cylindrical shell ring of the damping element.

EFFECT: strengthening the construction of buildings or structures, reducing their vulnerability when exposed to wind loads and earthquakes, improving their seismic safety, durability and residual life.
