PROTECTIVE FRAME-FABRIC STRUCTURE Russian patent published in 2016 - IPC E04H9/00 E04B1/32 

FIELD: military science.

SUBSTANCE: invention relates to military science, particularly, to military structures for protection of personnel, control stations, clinics and field hospitals, raised at fortification equipment of positions and areas of location. Protective frame-textile structure consists of frame of the main room and inlet device assembled of annular elements and shell. Bearing frame is made of composite materials of circular arched structure with end protective diaphragms and fitted protective-tight doors of the main and standby inputs, connected to each other in a single structure by shell of watertight technical polyamide fabric attached from the inside to circular arched elements by means of tie-strings and by boltings with bars to diaphragms. To ease repair or replacement of damaged arc elements there is an opening at the bottom of shell, which is cross-linkable manually by capron cord. To increase protective properties of the skeleton there may be created a concrete screen based on metal grids or multilayer fibrous fabric, filled with cement-sand composition of fast hardening after its impregnation with water.

EFFECT: invention allows to improve operation and transport characteristics of the structure, ease manufacturing technology, increase reliability, protective properties, extend the useful area.
