Description

The invention relates to field fortifications for the protection, work and leisure of personnel. Such a construction can be used in the engineering equipment of the areas of the location of troops, rear command posts, medical posts and field hospitals, as well as for the construction of short-term temporary work and residential premises in areas of natural disasters and technological disasters.

A known construction of a mobile structure (analogue, French application No. 2486123 of 1982, IPC Е04Н 11/121), consisting of modular elements of racks and panels, assembled among themselves by sequentially increasing the volume of premises.

The disadvantages of this design are the large mass of modular elements of racks and panels, the significant complexity of the assembly of the structure, as well as its low protective properties.

A known construction of a transportable structure - a dormitory (prototype, FRG application No. 3508188 from 1986, IPC Е04Н 1/12), consisting of the core of the main building, corresponding to the dimensions of the container, in which to create the necessary additional area and increase the internal space, one side wall can move outward and communicate with other end walls folded in the form of an “accordion”, and to increase the volume, additional panels of floor and ceiling elements are provided.

The disadvantage of this design is the significant complexity of deployment from transport to operational position and vice versa, due to the large mass of wall elements, floor and ceiling panels forming additional (auxiliary) rooms.

The objective of the proposed technical device is to reduce labor costs when deploying (curtailing) the structure, reducing the time to prepare it for operation, increasing the protective properties and ensuring large capacity.

This is achieved by the fact that in the folding fortification structure the skeleton is made in the form of a mobile container with two protective and hermetic doors and built-in entrance platforms, which is reinforced at the ends by two hinged pivoting panels and two pairs of folding hingedly attached to increase the protective properties. to the sides of the upper panels, while to increase the usable area to its middle part, hinged support frames are pivotally fixed, creating a joint in the working position but with rotary and folding panels two side auxiliary rooms.

The essence of the proposed invention is illustrated by drawings: figure 1 shows a General view of a folding fortification; figure 2, 3 respectively show the plan of the structure when folded and in the unfolded position; 4, 5 show, respectively, a longitudinal section of the structure when folded and a cross section in the expanded position; figure 6 - node laying in the transport position of the rotary and folding panels; in Fig.7 - the connection node between the rotary and folding panels when installing a fortification with increased usable area.

The claimed fortification structure (Fig. 1) contains a skeleton made in the form of a container 1, with two protective and hermetic doors 2 and built-in entrance tambours 3. The container for enhancing the protective properties is reinforced externally, at the ends, by two articulated panels 4, and on top of the coating - by two pairs of folding top panels 5. which are hingedly connected to each other and with the sides 5. To increase the usable area, the supporting frames 6 with mounting clips 7 and locking bolts are hinged to the middle part of the sides 8, creating together with the front and upper panels 4, 5 two side auxiliary rooms 9. For the convenience of operation and creating comfort in the building, elements of internal equipment (tables, chairs, hanging bunks, etc.) and life support systems (lighting, ventilation) are provided in advance , heating and power supply), and also additional protective and hermetic doors 2 are installed on the end panels 4.

The fortification in the folded position (Fig. 1) can be operated on the surface of the earth or installed in a foundation pit and bunded with soil to increase its protective properties with the equipment of inputs from local materials. Transportation of the structure to a new place of operation or to a warehouse for its storage is carried out by a KamAZ car or other means of transport. To carry out loading and unloading and installation and dismantling works, the structure has corresponding mounting loops 10.

The construction and operation of a fortification with an increased usable area can be carried out on the surface of the earth or in a pit with its protective-masking layer dipping in the following sequence. First, a flat platform with dimensions of 7 × 7 m is prepared on the surface of the earth or in the pit, on the middle part of which a construction package is installed using a truck crane. Then manually hinged end panels 4 and support frames 6 are manually retracted (opened) to the working position (Fig. 3). After that, with the help of a truck crane, the upper folding panels 5 are installed on them (Fig. 5). The panels are fastened to each other and with the supporting frames 6 by means of mounting clips 7, special grips from the corners 11 and locking bolts 8. After assembling the skeleton of the structure, immediately before it is dipped with soil, ventilation and smoke pipes are installed with protective devices, connectors are connected to each other elements of life support systems, communication lines and external energy supply are laid. The floor in the auxiliary rooms 9 is arranged from a reinforced film material or linoleum 12.

Folding the structure into transport position and removing it from the pit is carried out in the reverse order. Communication lines and external power supply are being rolled up, life support systems are disconnected, rolled floor material and soil debris are being removed. After that, the locking bolts, ventilation and chimneys are removed. When the structure is located on the surface of the earth with the help of a truck crane, the upper folding panels 5 are removed and placed in the transport position (Fig. 6). At the same time, the articulated end panels 4 and support frames 6 are manually transferred to the transport position, which are then fixed to the container with locking bolts 8. When the structure is located in the foundation pit, the end panels 4 and support frames 6 are transferred to the transport position after removing it from the foundation pit and installing it on the surface of the earth. The structure folded into the package is transported to a new construction site or to its storage area.

Increasing the longitudinal and lateral stability of the deployed structure, in order to increase its useful area, is achieved by placing articulated support frames 6 (Figs. 3, 4) on both sides of the container 1 with adjusting clips 7 and lock bolts 8. In addition, to increase the strength and the rigidity of the structure of such a structure, the upper folding panels 5, when installed on the end panels 4, are mutually supported and connected to each other by means of corner grips 11 (Fig. 7). Improving the security of the structure is ensured by placing it in a pit with a protective-camouflage soil bunding with a thickness of 30 to 50 cm. In this case, to prevent the bottom of the panels 4, 5 from deflection from spreading with their soil, they are pinched in it to a depth of 15-20 cm (Fig. 5 ), and in special conditions, if necessary, can be additionally fixed from the inside with anchor stakes.

The possibility of early installation inside the container 1 of the necessary set of internal, technological (special) equipment and spare parts improves usability and ease of use, significantly reduces the time of assembly or disassembly of the fortification structure.

According to the results of theoretical studies and calculations, it was found that the proposed technical solution allows to simplify the construction of the structure, reduce its weight due to the use of support frames and the use of a floor made of lightweight roll material, reduce the deployment time from transport to operational and vice versa due to limited use locking bolted joints, to increase the convenience of transporting the structure, folded in a package, and to improve operating conditions both when folded and in the expanded position.

The advantage of the proposed design over the known analogues is the lower mass, cost and deployment time (coagulation) of the structure by about 10-15%. This design of the structure provides comfortable conditions for work and rest in it with sharp changes in the temperature of the outside air due to the presence of a heat-insulating layer in its design and the possibility of the safe use of any heating and lighting equipment.

The readiness of the invention for implementation is characterized by the development of technical proposals for the design of a folding fortification.

The materials of the proposed technical device are planned to be used when performing research and development work "Transform" to create transformable military fortifications of variable volume.
