TENT FOR TEMPORARY ACCOMMODATION OF PEOPLE IN FIELD Russian patent published in 2018 - IPC E04H15/34 E04B1/82 G10K11/16 

FIELD: satisfaction of human vital requirements.

SUBSTANCE: invention relates to the design of frame tents for temporary accommodation of people and/or temporary storage of materials and equipment in the field. Tent contains a fabric awning that forms the roof, side walls and end walls with an entrance opening, the floor and the internal collapsible frame of several sections, each of which consists of racks and connecting arcs with side branches, the sections are connected by longitudinal posts that are fixed in the lateral branches of the connecting arcs, and the lower posts of the frame are inserted with their lower ends into the slots made in the floor of the tent for fixing the frame, the lower ends of the frame sections are additionally connected by locking longitudinal and transverse links, with windows and/or air vents located on the walls of the tent, and in the roof there is a hole for the chimney, as the material of the fabric awning material is used, which includes an intermediate layer of plain weave polyester fabric and a double-sided polyvinyl chloride coating, for accommodation of people 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 multilayer structure in the form of two layers: sound-reflecting layer adjacent to a rigid wall, and sound-absorbing layer adjacent to a perforated wall, layer of sound reflecting material is made with complex profile, composed of evenly distributed hollow tetrahedrons, and rockwool-based mineral wool, or URSA-type mineral wool, is used as a sound-absorbing material or basalt cotton wool of P-75 type, or glass wool with a fiberglass cladding or foamed polymer, the surface of fibrous sound absorbers is treated with special porous paints that let in air, or is covered with breathable fabrics or non-woven materials, while a material based on aluminum-containing alloys is used as a sound-reflecting material, followed by 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: improving the performance properties of a tent for people accommodation in winter conditions with high noise levels, for example, on temporary airfields to evacuate the population affected by flooding during spring floods.
