Description

The utility model relates to tent structures intended for temporary accommodation of people in field, including extreme, conditions. It can also be used for organizing pre-fabricated hospitals, command posts, utility rooms, field canteens, shelters for equipment and machinery, and performing other functions during emergency rescue operations in the event of natural disasters, catastrophes, and for other purposes.

Tents having an inflatable frame, the so-called pneumoframe tent, are known. An example is the design of the tent of the NGO "Module" [information can be found on the Internet at: http://www.pnevmomodul.ru/pnevmokarkas/]. The tent is an arched type inflatable structure. The pneumatic module of the tent has the following main elements: pneumoframe, casing, inflatable doors, bottom. The single-circuit pneumoframe is made of rubberized fabric on both sides and consists of arches connected in a single structure. The tent has an outer casing, which is made of rubberized fabric, and an inner casing, which is made of nylon. The air space between the outer and inner cladding creates thermal protection of the internal volume of the pneumatic module. The casing provides through holes for the supply of warm air from the heating and ventilation units and openings for the input of electric cables. Pneumatic doors, which are located on the end faces of the pneumatic module, as well as the frame, have external and internal casing, and are made of the same materials as the casing of the module itself. The bottom (glued floor) is made of waterproof rubberized fabric. The tent also has an insulated floor made of rubberized waterproof fabric and sections of the insulating layer of foam polymer glued to it. Tents of this design have sufficiently high thermal insulation properties, but during operation it is necessary to periodically pump air to maintain the required volume between the skin. In addition, they are not reliable enough, because in case of possible violation of the seals (destruction of the seams, puncture of the shell), the air goes outside, parts of the tent are blown away and it settles.

Known solutions aimed at improving the design of the pneumatic frame of the tent. So in the patent of the Russian Federation No. 2182811, publ. 05/27/2002 the pneumoframe tent has a removable tent with an external canopy, inner lining (insulation), an internal canopy, also has a floor and an inflatable frame. An additional pneumatic drainage is installed inside the inflatable frame to remove residual air, made in the form of perforated hoses communicating with each other through adapters and connected to the air inlet / outlet fitting. The presence of a pneumatic drainage system increases usability, as It allows to significantly reduce the process of folding the pneumoframe tent after operation, since pneumatic drainage helps to remove residual air. However, this design, as described above, does not increase the reliability of the tent with mechanical damage to the frame elements.

As a prototype, the design of the tent, described in the USSR AS No. 1118339, publ. 10/15/1984, in which the inflatable cage is made sectional and consists of interconnected individual elements: air arches, pneumatic struts, upper and lower struts (longitudinal beams - runs), an inflatable sectioned floor and an upper waterproof coating. Each section has its own air panel for inflation. Such a tent has increased reliability, because sections are isolated from each other and damage to one of the sections will not lead to subsidence of the entire frame. However, the sections have different internal volumes, which excludes the possibility of their simultaneous inflation from a single discharge system. Each section should be inflated and, accordingly, deflated separately. Thus, the prototype design is unacceptable for the quick erection and dismantling of a large-volume tent, designed to accommodate (accommodate) several people or to shelter equipment and machinery. In addition, the tent does not provide thermal insulation of the outer cover.

The utility model is based on the task of expanding the arsenal of funds and creating a structure of a sufficiently voluminous tent with a pneumoframe, which has increased reliability. The achieved complex technical result is the exclusion of the possibility of deflating the entire frame when a separate element is damaged, and ensuring the possibility of simultaneous inflation (and blowing) of all sections of the frame. An additional result is an increase in the thermal insulation properties of the tent.

The problem is solved by changing the design.

The inventive tent has a sectional pneumoframe, floor and tent, forming a roof, side walls and end walls with an opening for entry. It differs from the prototype in that the pneumoframe is made sectional with a dual-circuit inflation system with sequential alternation of sections of the contours in the direction along the axis of the tent. Each section consists of a cylinder of the transverse arch with rafters and supporting posts, to which longitudinally oriented cylinders are attached, forming runs. In the context of this application, the term “cylinders” is used to mean shells that, when inflated with air, form cylindrical shapes, and the construction term “run” is used in the meaning of “longitudinal element”, “horizontally located longitudinal beam”. The cylinders forming the runs of the adjacent sections are separated from each other by blank partitions to prevent air from entering from sections of one inflation circuit into sections of another circuit. Neighboring sections of one circuit are interconnected by tubes passing in longitudinally oriented cylinders of a section of another circuit located between them. These tubes are fixed in the annular partitions between the sections, and these annular partitions have axial openings for air to pass through the tubes.

In a preferred embodiment, the tent has an external tent and isothermal insulation. As a material of isothermal insulation, a multilayer material is used, including a synthetic winterizer layer and a layer of aluminum metallized polypropylene film, enclosed between the outer layers made of a polyester fabric, the layers being interconnected using hot-melt adhesive, applied by dots or in separate strips to the surfaces to be joined.

If necessary, the tent may have an additional sunshade, mounted above the outer tent with a gap equal to the diameter of the pneumocylinders located between them.

The insulated floor, in a preferred embodiment, is made of a foamed polymeric material, for example, polyethylene foam, packaged in a waterproof polypropylene fabric.

In order to better demonstrate the distinctive features of the utility model, as an example, not having any restrictive nature, the preferred embodiment is described below. An example implementation is illustrated by the figures of the drawings, which show:

FIG. 1 is a diagram of a pneumoframework,

FIG. 2 - tent with an additional sun awning, which can also be used as a camouflage.

-образную конструкцию с перегибом на коньке палатки. У баллонов торцевых арок имеются односторонние поперечные ответвления, то есть

-образная конструкция. Продольно ориентированные баллоны 7 закрыты на торцах, то есть, образованы глухие перегородки 8 между баллонами смежных секций. Таким образом, пневмокаркас образован цельными баллонами, образующими арки, а его прогоны (продольные балки) составлены из коротких продольных баллонов секций, то есть, прогоны выполнены составными и имеют внутренние перегородки.In FIG. 1 is designated: 1, 2, 3, 4 - sections of the pneumatic frame (1, 3 - sections of the first air circuit, 2, 4 - sections of the second circuit), 5 - cylinders of the transverse arch, 6 - rafters of the transverse arch. To simplify the perception, the diagram does not show the ridge run and support legs. The cylinders 5 of the transverse arches are made of PVC material and are longitudinally oriented cylinders 7, which, when assembled, form the girders, are tightly attached to them (for example, by heat sealing or with glue). Thus, each section has a structure based on a cylinder that forms a transverse arch, and transverse branches (fragments of runs) depart from it in opposite directions, that is, the section has

-shaped design with an inflection on the ridge of the tent. Cylinders of end arches have one-sided transverse branches, i.e.

-shaped design. The longitudinally oriented cylinders 7 are closed at the ends, that is, blind partitions 8 are formed between the cylinders of adjacent sections. Thus, the pneumoframe is formed by integral cylinders forming arches, and its runs (longitudinal beams) are composed of short longitudinal section cylinders, that is, the runs are made integral and have internal partitions.

The connection between the cylinders of one circuit is made using tubes 9. These tubes 9, connecting adjacent sections of one circuit (in Fig. 1, sections 1 and 3), pass in longitudinally oriented cylinders of the section of the other circuit, which is located between them (section 2). The tubes 9 are coaxially covered by a cylindrical shell of longitudinally oriented cylinders of section 2, belonging to the same run, cylinders of one "tier"). For air to pass through the tubes, part of the partitions, namely, partitions 10, has the shape of a flat ring with an axial hole, and the ends of the tubes 9 are fixed on these partitions 10.

The boost system is double-circuit. In FIG. 1 is also indicated: position 11 is the blow-off valve of the sections of the primary circuit and, accordingly, 12 is the air flow of the blow-in sections of the primary circuit (dashed arrows), 13 is the valve of the blow-in sections of the primary circuit (14) is the air flow of the blow-in sections of the secondary circuit (arrows of the solid line) .

The pneumoframe is made as follows. First, partitions are glued into the shells forming the fragments of the girders: blind (8) and with axial holes (10) according to the scheme. Then, the ends of the tubes 9 are glued into the partitions 10 with holes, after which the connecting shells with an unclosed arch are assembled, and then the arch is closed.

The construction of the tent as a whole is shown in FIG. 2.

The outer awning 15, which is the top layer of the multilayer awning, is mounted on top of the air frame and is made of a material traditionally used for these purposes, for example, PVC material, and does not have sewn seams (all seams are formed by thermo or high-frequency welding).

The internal isothermal insulation 16 is attached from below to the air frame using belts with half rings and has the ability to adjust the tension, as well as the ability to remove it for processing from contamination.

The waterproof floor 17 of the tent is also made of PVC material, and has an anti-flood board along the perimeter. The insulated floor 18, located under the waterproof floor 17, is made of foamed polymer (polyethylene foam), packaged in a waterproof polypropylene fabric. This floor is more environmentally friendly than rubber, while it has high thermal insulation properties, and does not require talcum powder pouring, unlike rubber, during storage. In the case of manufacturing a pneumocarcass with a lower band around the perimeter, you can not use the anti-flooding board.

The tent has an inflatable door, in the manufacture of which two-layer material “Airdek” was used, the sufficient rigidity of which allows you to preserve the shape of the door during operation [for information, see the Internet at http://activerest.com.ua/materials/]. The tent has windows equipped with blinds, inserts made of carbon fiber plastic or plexiglass, or blinds made of transparent PVC material and mosquito nets, has inputs for heat-pumping equipment and electrical wiring.

The thermal insulation properties of the tent are ensured through the use of a multilayer material for the manufacture of internal isothermal insulation. The material has four layers. The inner layers are represented by sintepon, usually used in the clothing industry as a heater, and aluminum metallized polypropylene film. An example is the BOPP film (BOPP), which is widely used in industry [information can be found on the Internet at http://www.daymondpack.ru/matall_bopp.html]. The function of this film is to reflect infrared radiation. The outer layers (top and bottom) of the insulation material are made of a tightly woven polyester fabric, they are reinforcing and do not support bacteriological substances, which is important when operating in the field. In this case, the layers forming the internal isothermal insulation are interconnected using hot-melt adhesive, applied by dots or stripes to the surfaces to be connected. Powder hot melt adhesive used in the clothing industry can be used. Such a combination of layers allows them to be securely fixed to each other and ensures the formation of additional air gaps, which increases the thermal insulation properties of the isothermal material as a whole.

For tents intended for use in countries with hot climates, it is advisable to use an additional sunshade 19. It is made of PVC material, or of lightweight material “polyoxford” (polyester fabric from thick threads). The optional sunshade 19 may have perforations that increase the wind resistance of the tent.

This awning 19 is fixed with stretch marks on additional pneumocylinders 20 located on the outer tent 15 of the tent. An additional air gap, the thickness of which is determined by the diameters of the air cylinders 20, further increases the thermal insulation properties of the tent. Awning 19 can fulfill the function of camouflage when drawing on it the appropriate terrain pattern. The outdoor awning and the optional sunshade are secured with stakes and stretch marks.

When the tent air frame is inflated, air is supplied to both circuits simultaneously, which allows you to set up a large volume tent (for example, a mobile hospital) quite quickly. Moreover, thanks to the blind partitions 8, air does not flow from sections of one circuit into sections of another. The frame is also blown out simultaneously by pumping air.

In the case of mechanical damage to one of the cylinders, the air leaves it outside, but at the same time the pressure is redistributed in the circuit elements due to the tubes 9, and air enters the damaged cylinder from other cylinders of this circuit. Deflation of a damaged cylinder slows down, cylinders of this circuit slowly deflate, and the tent begins to sag. At the same time, cylinders of another circuit, alternating with damaged cylinders, remain inflated and provide “survivability” of the tent until the fault is eliminated.

Isothermal insulation of the claimed utility model is made of materials widely used in industry. For its manufacture, the use of special equipment and special expensive technologies is not required. Tests of the material showed its high heat-insulating ability, namely, the thermal conductivity of this material is 0.04 W / m · K. The high heat-insulating properties of the applied four-layer material, the ability to reflect infrared radiation of an aluminum metallized polymer film, combined with the thermal insulation properties of the pneumatic frame itself, make it possible to use the tent in harsh climatic conditions. The tents made according to the utility model have the following characteristics:

Climatic conditions of use: - outdoor temperature, ° C -40 / + 50 - wind speed up to 25 m / s (without dust), or up to 20 m / s with dust saturation up to 5 g / m3. - atmospheric pressure corresponding to an altitude of 0-3000 m - relative air humidity up to 99%, at a temperature of plus 25 C ° - snow load up to 25 kg / m ²

The air temperature inside the tent when using external heaters, not lower than + 23 ° C.

Floor temperature + 10 ° C when using floor insulation and an outdoor temperature of -50 ° C.
