Description

The utility model relates to military fortifications for the protection of personnel, command posts and medical posts during fortification equipment of positions and areas of the troops.

The LKTS lightweight frame and fabric structure is known as an analogue (“Manual on Military Engineering for the Soviet Army”, Military Publishing House 1983, pp. 83-87), consisting of the core of the main building, protective-hermetic and draft inputs, assembled from ring frame elements and shells made of reinforced film material.

The disadvantages of this device are the design complexity, the complexity of the construction and extraction, high cost and low operational characteristics of the structure.

Known collapsible structure LKS-2 prototype (Manual "Military fortifications", Military Publishing House 1984, p. 187-193), consisting of the core of the main building and the entrance with a protective and hermetic hatch, assembled from the ring elements of the frame and shell from reinforced film material.

The disadvantages of this device are the complexity of the design and the technology of its manufacture, a large mass of the kit, high cost and low operational characteristics of the structure.

The objective of the proposed technical device is to simplify the design and technology of its manufacture, increase reliability, reduce the weight of the kit and its cost, improve transport and operational characteristics.

The solution to this problem is achieved by the fact that in the proposed structure, the entrance with a protective and hermetic hatch is made at the end of the main room, and the ring frame elements are made with a telescopic lock and stopper for reliable fastening of the reinforced film sheath by means of pockets sewn to it from the inside and eyelets installed along the edges of the longitudinal sides, at the same time, a packing cover is attached to the end face of the shell together with the protective and hermetic hatch, which forms the entrance vestibule in the expanded position.

The essence of the proposed utility model is illustrated by drawings, which depict: in Fig.1 - shows a General view of a light frame-fabric structure in the expanded position; Figures 2 and 3 show longitudinal and transverse sections, respectively; figure 4 - shows the structure in packaged form; figure 5 shows the annular element of the frame; Fig.6 is a bottom view of the panel of the main room from a reinforced film sheath with sewn pockets for ring elements and mounted grommets along the edges of the longitudinal sides; in Fig.7 - shows a variant of connecting two or three sets of structures with each other for the end rings with a partition device in the form of a curtain.

The claimed lightweight frame-fabric construction, consisting of the skeleton of the main room 1 and entrance 2 with a protective and hermetic hatch 3, assembled from the ring elements of the frame 4, and a shell 5 of reinforced film material, characterized in that it has an entrance 2 with a protective and hermetic the hatch 3 is made at the end of the main room 1 (Fig. 1, 2), and the ring elements of the frame 4 are made with a telescopic lock 6 and a stopper 7 (Fig. 3, 5) for reliable fastening of the reinforced film sheath 5 by means of pockets 8 sewn to it from the inside and the cage ov 9, installed along the edges of the longitudinal sides (6, 7), while to the end of the shell 5, together with a protective and hermetic hatch 3, a packaging cover 10 is attached, forming in the expanded position of the entrance vestibule 11 with the outer ring element 12 (figure 1 , four).

For ease of operation, hanging bunks-tables 13 and folding chairs 14 (FIG. 2) are installed inside the structure. To increase the protective properties, the structure is erected in a pit or in the folds of the terrain (in ravines, pits, etc.) and bunded with soil. In this case, the longitudinal stability of the structure is achieved by pinching the ring elements with soil, attaching to the blind end of the anchor plate 15, and installing from each end two brackets 16 with anchors 17 (figure 2).

In the transport position, the structure is folded into a compact package (figure 4). To do this, first, hanging bunks 13 and chairs 14 are folded inside and suspended in a vertical position. After that, the structure is folded “accordion” into a bag and pulled onto it as a packing cover 10 of the entrance platform 11 with the telescopic lock disconnected 6. After laying in the package of anchor guy wires 16 with anchors 17 and anchor plate 15, the telescopic lock of the outer ring element 12 is fixed with a stopper 7 and is additionally pulled together in four places by packing belts 18.

The package is transported (figure 4) by a calculation of 4 (3) people for the packing belts 18 or directly for the protective and hermetic hatch 3. The structure is transported by any type of transport, including airplanes and helicopters, with the possibility of delivery to the combat area by parachute.

To deploy the structure to the operational position (Figs. 1, 2, 4), first remove the packing belts 18 and disconnect the telescopic lock 6 of the outer ring element 12. Then the package is pulled out at the ends, an entrance vestibule 11 is made from the packing case 10, the telescopic lock bis is connected using anchor braces 16 with anchors 17 and anchor panels 15, the structure is fixed in the unfolded position in the pit for subsequent soil debris.

The manufacturing technology of the structure allows the possibility of organizing mass production in a small enterprise without difficulty using purchased materials and products. To do this, prepare:

- the panel of the main room 1 of reinforced film material with sewn pockets 8 and installed grommets 9 (Fig.6);

- a blind end face of an ellipsoidal shape with an anchor plate 15;

- packing case 10 (entrance vestibule 11) with a pocket 8 for the outer ring 12;

- ring elements of the frame 4 with a telescopic lock 6 and a stopper 7;

- a protective and hermetic hatch of entrance 3 with a set of bolts 18 for fastening to the end ring of the shell;

- anchor guyings 16 with anchors 17.

For the manufacture of a reinforced film sheath of a structure, first a blind end is sewn to the main room panel 1, and then a packing cover 10 (entrance vestibule 11) is sewn to the opposite end. To assemble the structure, first with the help of an open lock 6, annular elements 4 are inserted into the pockets 8, scrolling them inside the shell, and the telescopic assembly together with the grommets is fixed with a stopper 7. Then, with the help of the bolts 19, a protective and hermetic hatch 3 is connected to the end ring 3. After that attach anchor brackets 16 with anchors 17 to the upper part of the end rings 17. The fabricated structure is folded into a bag (Fig. 4) and delivered to the troops. Deployment or collapse of the structure is carried out by calculation of 4 people in 6-8 minutes. The dismantling of the structure in the troops is carried out only if it is necessary to repair it.

The proposed design of a light frame-fabric structure provides the convenience of its use as a single universal tool for the protection of personnel, control points and medical points. If it is necessary to significantly increase the usable area, especially for control centers and medical centers, two or three sets of structures can be connected to each other by means of fastening the end rings one after the other (Fig. 7) by means of a telescopic lock 6 and a stopper 7. When one, a common entrance (exit) in the blind end of the first structure, a passage is formed, closed by a curtain from the anchor plate, and on its end ring an outer ring 12 of the entrance vestibule is fixed using a telescopic lock 6 and 11 of the second structure. When two entrances are installed, the main and the spare, two sets of structures are connected by ends. In this case, the completely deaf end is removed in the second set, and in the first they arrange (cut out) the passage, which is closed by a curtain from the anchor plate. The advantage of such a structure is the presence of two protective and hermetic inputs (outputs).

The readiness of the proposed technical device for pilot testing is confirmed by the presence of drawings and a list of materials of domestic production suitable for the manufacture of a working sample of a light frame-fabric structure.

Theoretical studies and calculations have confirmed that the proposed construction according to the main criterion for assessing "application efficiency - cost" has indicators that are approximately 20-30% higher compared to existing analogues.

The main advantage of the proposed structure over the known analogues is its simplified design, due to the arrangement of the main room in the form of a cylinder with an entrance at one of the ends; combining the packing case with the entrance vestibule, making the reinforced shell with pockets sewn from the inside to securely fix the ring elements arranged with a telescopic lock and stopper. Such a technical solution provides:

- simplification of manufacturing technology;

- improving the reliability of the design;

- minimum time for curtailing and deployment of the structure;

- the possibility of a significant increase in usable area in a twin version;

- minimum weight and size parameters in the transport position;

- cost reduction;

- high operational performance.

The optimal dimensions of a light frame and fabric structure in the operational position (4.0 × 1.4 × 1.6 m), a minimum weight (up to 100 kg) and folded dimensions (1.7 × 0.65 m) ensure its convenience use in the army, including in parachute and other special units.
