FLEXIBLE SOUNDPROOF FENCE Russian patent published in 2021 - IPC G10K11/00 

FIELD: anti-noise screens.

SUBSTANCE: invention relates to noise canceling screens. The flexible screen is a multi-layer structure - the outer layers of the fence are made of a set of plates of polymer materials, upper and lower, in the form of separate geometric shapes, for example, rectangular. The shape of the plates has been chosen to ensure gap bridging. At the same time, a cutout is made in the upper plates, which provides flexibility of the fence and, "transforming" in the process of operation, ensures a constant overlap of the gap between the lower plates to the middle layer, which is represented by a flexible material, for example, from carbon or basalt fabric. The outer plates are fixed with screws with a flexible intermediate layer on a carrier mesh, for example made of fiberglass. Vertical support posts made of square pipes have molded projections with holes for fasteners. The uprights are made of polymer composite materials (for example, glass and carbon fiber reinforced plastics) and are filled with sound-insulating foam inside to avoid loss of sound insulation. In the lower part of the rack, there is a flange with reinforcing ribs for fastening to the foundation.

EFFECT: technical result is an increase in strength, durability, manufacturability, ease of transportation, installation and maintenance.
