Abstract: FIELD: satisfaction of human vital requirements.SUBSTANCE: invention relates to the construction of frame tents. Tent contains a fabric awning that forms the roof, side walls and end walls with an opening for entry, the floor and the internal collapsible frame of several sections, each of which consists of racks and connecting arches with lateral branches, and sections are connected by longitudinal racks which are fixed in lateral branches of connecting arcs, and the bottom frame stands are inserted with bottom ends into slots made in the floor of the tent for fixing the frame, while the lower ends of the frame sections are connected additionally by fixing longitudinal and transverse connections, with windows and/or ventilation holes arranged on the walls of the tent, and in the roof there is a hole for the chimney, the material that reflects infrared radiation and contains a textile base, a metallized and microporous membrane layers is used as the material of the fabric awning, polyester textile material with water-repellent impregnation is used as the textile base, the metallized layer is represented by titanium nitride, and the microporous membrane layer is made of thermoplastic polyurethane resin and is placed between the textile base and the metallized layer, while titanium nitride is deposited on the microporous membrane layer at the atomic-molecular level in the amount of 1–2 g/m, and the textile base contains a camouflage pattern, while for accommodation in winter conditions with a high noise level, the fabric awning of the tent is warmed outside by a layer of heat and sound insulation covering consisting of rigid and perforated surfaces, between which there is a multi-layer sound-absorbing structure in the form of a rigid and perforated walls, between which there are two layers: sound-reflecting layer adjacent to the rigid wall and sound-absorbing layer adjacent to the perforated wall, the layer of sound-reflecting material is made of a complex profile consisting of uniformly distributed hollow tetrahedra, and mineral wool on a basalt basis is used as a sound-absorbing material, or mineral wool, or basalt wool, or glass wool with a glass fiber cladding, or foamed polymer, the surface of fibrous absorbers is treated with special porous paints that let the air, or is covered with air-permeable fabrics or non-woven materials, the material based on aluminum-containing alloys is used as the sound-reflecting material with their further filling with titanium hydride or air, and the sound-reflecting layer adjacent to the rigid wall is made with perforation of sound-reflecting material of a complex profile consisting of uniformly distributed hollow tetrahedra,that allow reflecting sound waves falling in all directions, the perforation on the sound-reflecting layer is performed by analogy with the orifice holes, which are the mouth of Helmholtz resonators, the capacity of which is determined by the volume of the sound-reflecting layer and the rigid wall of the sound-absorbing element adjacent to it.EFFECT: technical result is an increase in performance properties and the provision of a normal accommodation microclimate.1 cl, 5 dwg
