COLLAPSIBLE ISOLATED THREE-DIMENSIONAL STRUCTURE Russian patent published in 2004 - IPC

FIELD: building, particularly structures for reducing noise and vibration from remote sources.

SUBSTANCE: structure has at least one base module and at least one flooring module connected by side walls thereof with the use of detachable connecters. Base module is secured to fixed base by support units. Side walls are made of wall modules and at least of one door unit and of one window unit. Support unit is made as body filled with resilient material for impact noise and mechanical vibration absorption. Inner panel layers are formed of material having coefficient of acoustic vibration energy loss exceeding that of outer layers. Wall module and flooring module are of multi-layer structures having different absorption coefficients and coefficients of acoustic vibration energy loss. Wall module and flooring module layers from structure interior side are formed of sound absorbing material having coefficients of acoustic vibrations loss exceeding that of another layers. These modules together with door and window units have hollow frames filled with sound absorbing material. Joints between modules and door and window units are filled with sealing members along the full joint length.

EFFECT: reduced standard time of sound signal reverberation inside structure, increased energy losses of acoustic vibration from remote sources and from solid surface on which structure is mounted.
