TENT FOR PUBLIC TRAINING IN EMERGENCY SITUATION ENVIRONMENT Russian patent published in 2015 - IPC E04H15/00 

FIELD: physics.

SUBSTANCE: tent for public training in an emergency situation environment comprises a fabric tent which forms a cover, side walls and end walls with an entrance opening, a floor and an internal dismountable frame consisting of multiple sections, each consisting of cross bars and connecting arcs with side outlets. The sections are connected by longitudinal bars which are fixed in the side outlets of the connecting arcs. The cross bars of the frame are inserted by their lower ends into sockets on the floor of the tent to fix the frame. The walls of the tent have windows and/or ventilation holes. The cover has a hole for a smoke pipe. The material of the fabric tent used is a material which reflects infrared radiation and contains a textile base, a metal-coated layer and a microporous membrane layer. The textile base used is a polyester textile material. The metal-coated layer is titanium nitride, and the microporous membrane layer is made of a thermoplastic polyurethane resin and is placed between the textile base and the metal-coated layer. The polyester textile material is soaked with cement slurry. The tent is provided with at least one additional layer of fabric material which is mounted outside the fabric tent and soaked with a consistency based on liquid polyurethane with addition of a mixture consisting of equal portions of ground glass bits, mica and lead crumbs or shavings.

EFFECT: invention broadens operational capabilities of the tent by reducing the effect of ionising radiation and simultaneously improving strength properties of the fabric tent while maintaining easy manufacture.
