Description

The invention relates to the construction and / or fortification and can be used in the external and internal fences of the territories of construction sites, road construction and repair sites, industrial enterprises, public places and other territories that require mainly temporary localization, and also as the simplest engineering structures of field fortification .

Known barrier element for the separation of traffic flows, made of rubber and having an elongated base, a groove is made on one end of the base, a mating protrusion on the other end, forming a connection of the barrier elements to each other, holes for mounting fasteners are made in the element, the shape grooves and protrusions are selected such that they form a swivel joint [description of the utility model to the patent of the Russian Federation No. 80169 dated 08/22/2008, IPC E01F 15/02, publ. 01/27/2009]. The task to be solved is the creation of new road marking elements. The technical result is an increase in the possible curvature of the bending of the separation barrier for marking the routes on the corners.

The disadvantages of this barrier element - a road marking element made of polymer - are its highly specialized purpose and difficulties associated with storage, reuse and the need for regular rejection of elements subjected to minimal mechanical stress or temperature changes.

A temporary construction fence is known, including a set of adjacent frame guarding load-bearing elements installed on the foundation, while it is provided with a support placed on the inside of the wall-bearing load-bearing elements and made in the form of an inclined angular brace, reinforced to the foundation and the load-bearing supporting element. Bearing elements can be installed with a technological gap [description of the utility model to the patent of the Russian Federation No. 38807 of 03/26/2004, IPC E04H 17/14, publ. 07/10/2004].

A disadvantage of the known construction fence is the need to equip a special foundation, which makes its use for other purposes, for example, as a field fortification, problematic due to the unacceptably low speed of construction.

A temporary construction fence is known, including a guarding element resting on a slab and linking their inclined brace, while the base plate is loaded with soil removed during excavation of the pit [description of the utility model to RF patent No. 107251 of 03.23.2011, IPC E04H 17/14, publ. . 08/10/2011]. Massive fencing reduces the amplitude of vibrations transmitted to existing buildings when piling in a construction pit, at the same time serves as an anti-noise barrier and allows us to save usable area when storing soil.

This technical solution has the disadvantages of the previous one.

Known block road separation barrier, comprising a housing made of plastic in the form of a hollow tank with upper and lower bases, with end walls and longitudinal walls located at an angle to the lower base, the housing having a cavity open from the bottom, with the upper base and each of the end and the longitudinal walls of the casing are made in the form of double panels with a gap between the latter, and the lower base is made in the form of a strip connecting the open ends of the corresponding double panels around the perimeter of the casing. In addition, one of the end walls of the casing has a latch located under it, made in the form of a boss, and the other end wall of the casing has a through hole to allow the installation of a latch of a nearby unit in it during the assembly of the road dividing barrier; each of the outer panels of the longitudinal walls has a number of reinforcing elements located at a distance from each other, and the road dividing barrier block is made possible to fill with liquid [utility model description to RF patent No. 68529 of 06/19/2007, IPC E01F 15/00, publ. . November 27, 2007]. EFFECT: provision during storage of the possibility of compact stacking of road separation barrier blocks in a stack.

The solution to the issue of laying blocks for storage and transportation is far from complete, because thick bilayer walls partially solve this problem. The reuse of blocks has not been taken into account, since the use of water for weighting requires high costs for its filling and release and drying after using the blocks for their intended purpose. In addition, the barrier based on these blocks is inoperative at low temperatures. And even when using more advanced materials, these products can be used exclusively for the declared purpose.

Known modular modular barrier for fences and signs, containing two separate parts, namely a vertical front part with two protrusions located in its lower region, forming two legs, and the rear part forming one Central leg and located obliquely relative to the front part, the front and the rear parts are connected to each other with the possibility of separation, while one of these parts has on its upper cross member corresponding to its edge, pivotally connected to the other part, a transverse groove d for a tongue-and-groove connection with corresponding protrusions extending from the upper edge of the other part, moreover, in the cross-sections of both parts, vertical holes are arranged opposite each other for the passage of the corresponding fixing fingers for connecting the individual parts of the modular barrier, the front part of which is mainly rectangular in shape with the lower protrusions forming these legs, and the rear part has the shape of an inverted isosceles trapezoid and its lower end forms a third leg, with each of the parts made of plastic and has on its surface a mesh structure with large openings for air passage [description of the invention to the patent of the Russian Federation No. 2371539 from 04.05.2005, IPC E01F 13/02, publ. 10/27/2009]. The task to be solved is the creation of a light and durable barrier made exclusively of plastic, which can be used both indoors and outdoors; having optimal stability, easily stacked when not in use, easily connected to other modules or barriers when creating fences or placing signs; having a flat vertical surface facing the pedestrian zone with information or advertising placed on it and not creating obstacles to the passage of air.

The disadvantage of a modular barrier is its precast openwork design. This limits its use, determined by pronounced decorative properties. It should also be noted the relative complexity of manufacturing the module, the complexity of mounting the barrier as a whole and the low speed of erection. In the process of dismantling the barrier and modules, many of the same type of details appear, which can lead to injury, a decrease in decorative properties and the dismantling of the structure.

A typical folding fortification structure is known, which consists of the core of the main room, made in the form of a mobile container with protective and hermetic doors and built-in tambours, reinforced at the ends and from above by pivoting panels, while to increase the usable area, hinged support frames are pivotally attached to its middle part, creating in the working position, together with the rotary and folding panels, two side auxiliary rooms [description of the invention to the patent of the Russian Federation No. 2469155 dated 12/26/2008, IPC EV0434, publ. . 12/10/2012]. The problem to be solved is the reduction of labor costs during the deployment (curtailing) of the structure, the reduction of the time for preparing it for operation, the improvement of protective properties and the provision of large capacity.

With all the advantages of the structure, it cannot be used for the operational localization of extended sections of the terrain. This is prevented by the large dimensions of the structure — it occupies a whole truck body — and the insufficient efficiency of its deployment and, to some extent, curtailment. Thus, the main disadvantage of this fortification is the inability to solve operational and tactical tasks in combat planning.

Known collapsible design of engineering structures, including reinforced concrete modular elements in the form of panels joined together by means of grooves and protrusions included in them with the possibility of changing the angle between the panels and fixing it with fixing nodes made in the form of splined joints, the mating parts of which are placed on protrusions and grooves in planes perpendicular to the surface of the panel, with each module on the one hand in the joint zone made with two protrusions formed by an angular cut and centrally a groove located between the protrusions, and on the other hand, an angular cutout located diagonally to the angular cutout of the opposite side, and a groove made symmetrically to the protrusion of the opposite side, while the grooves of the mating joints are made with a mounting gap equal to the height of the side face of the slot [invention to the RF patent No. 2016777 dated 05/12/1992, IPC5 Е04В 1/343, publ. July 15, 1994]. The problem to be solved is the expansion of the space-planning capabilities of structures while improving the manufacturability of the assembly.

Despite the fact that the engineering structure is versatile (it can also be used to build an extended fence), its use as a fortification has limitations associated with insufficient compactness in disassembled form, using significant resources for transportation to the construction site and with low speed of construction, for example, in conditions of possible shelling of the territory where it is supposed to be installed. As for dismantling, such structures, as a rule, are not reused, but are subject to further use or final disposal.

The problem solved by the inventions of the group, and the technical result achieved, are to create a universal fence, of almost unlimited length, made on the basis of a universal fence module, simple in design, compact during storage and transportation, possessing, in addition, the geometric required for a simple fortification (external type and form) and strength characteristics, as well as a significant reduction in the time for its construction and reduction of time for its dismantling , including with the possibility of subsequent operational construction in a new place.

To solve the problem and achieve the claimed technical result in the fencing module, characterized by the presence of a spatially curved continuous thin-walled case of a wedge-shaped cross-section, made with the possibility of joining one another during storage and / or transportation, and in its upper part the body includes a jumper between the walls and a section provided with a longitudinal guide groove, and the lower parts of the walls are provided with outward-facing flanges.

Besides:

- provided with a longitudinal guide groove section of the housing is made on the outside of the jumper;

- at least one edge of the jumper is made a fragment of the groove, passing into a longitudinal guide groove;

- the module is made of metal;

- the walls of the body are made with vertically oriented corrugations;

- the housing is equipped with an additional jumper of an arched convex shape, connecting the lateral ends of the walls on one of the sides;

- at least one wall of the housing includes at least one through hole;

- the edges of the walls of the housing and / or the edges of their flanges include through holes made with the possibility of placing them in the locking elements.

Also, to solve the problem and achieve the claimed technical result in the enclosure, characterized by the presence of interconnected unit modules as described above, which are preferably overlapped and connected by means of articulated rods, one end of the rods is mounted on one unit module and the other is located in the longitudinal the groove of the neighboring unit module with the possibility of displacement from one extreme position to another.

Besides:

- articulated rod includes at least one spherical head;

- the individual modules are additionally fixed relative to each other and / or the base surface on which they are installed by means of fixing elements located in the holes on the edges of the walls of the housing and / or on the edges of their outward flanges.

A known method of construction and dismantling of engineering structures [see RF patents No. 2016177 and No. 2469155]. The erection of structures consists in the sequential assembly of structural elements with the predominant use of manual labor. Dismantling of structures consists in reproducing the construction process in the reverse order.

And although the structural features of the structures can significantly reduce the time of their construction and accordingly reduce labor costs, in some cases, for example, with a sharp change in weather conditions (heat, cold, including frost, long rains, etc.), when insurmountable circumstances forces (fires, floods, unauthorized natural phenomena of public life, spreading epidemics, military operations, etc.) - the speed of construction is unacceptably low.

For the dismantling of well-known and any other structures that have not changed their physical nature, less stringent requirements are imposed in comparison with the requirements for their construction, because it is possible to wait for favorable conditions for work, however, even in this case, the dismantling time should be seriously reduced.

Also, the problem solved by the group’s inventions and the technical result achieved regarding the construction and dismantling of the aforementioned fencing based on universal unit modules are to significantly reduce the time required to deliver them to the installation site and erect the fencing, as well as reduce the time for dismantling it, including with the possibility of subsequent operational construction in a new place.

To this end, in the method of erecting the fence, characterized by the sequential installation of the previously mentioned unit modules of the fence, with its outward flanges on the lower parts of the walls on the base surface, and before installation, the unit modules of the fence sequentially enter one another and are connected in series with each other with the possibility of a subsequent fixed relative displacements by means of longitudinal guide grooves on one unit modules and interacting with them to form kinematic pairs of articulated rods mounted on adjacent adjacent unit modules, while the fencing modules are placed on a mobile platform and deployed with their outward flanges in the direction of its movement at an angle of no more than 90 °, and the sequential installation of single modules is carried out by dumping outward flanges to the base surface of at least the first of them. Besides:

- the angle α of the turn of the outward flanges of the fence modules to the base of the mobile platform is preferably calculated by the formula:

α = 90 ° -arctg (h / a),

where h is the height of the module fencing;

a - the length of the module fencing;

- a protective coating with antifriction properties is preliminarily applied to rubbing and contact surfaces;

- unit modules are fixed relative to each other and / or the base surface motionless.

In addition, in the method of dismantling the fence erected by the previously mentioned method, characterized by sequential removal from the base surface of the individual modules of the fence and their placement on a mobile platform with the entry of one into the other, while the unit modules are sequentially fixed relative to each other by means of longitudinal grooves on one unit modules and the articulated rods interacting with them, mounted on adjacent unit modules, by turning the base of each module towards two the mobile platform is reduced to an angle of not more than 90 °.

Besides:

- during the removal of single modules, at least a portion of the rubbing and contact surfaces is coated with a protective coating with antifriction properties;

- the dismantled fence is placed on a mobile platform with a turn of the bases of the individual modules at an angle of not more than 90 ° in the direction opposite to the direction of their removal.

The fencing module 1 includes a spatially curved solid thin-walled, preferably metal casing 2, wedge-shaped, for example, Λ-shaped cross-section, made with the possibility of joining one another during storage and / or transportation, and in its upper part, the housing 2 includes a jumper 3 between walls 4 and 5 and provided with a longitudinal guide groove 6, as a rule, a rectilinear section 7, and the lower parts of the walls 4 and 5 are equipped with outwardly directed flanges 8.

The definition of the term "thin-walled" is an engineering or building structure, the hallmark of which is a very small wall thickness compared to their dimensions. For reference: thin-walled structures include shells, domes, roofs, fences, screens, dividing walls, special profiles, etc.

Equipped with a longitudinal guide groove 6, a section 7 of the housing 2 is made on the outside of the jumper 3, and at least one edge of the jumper 3 is made a fragment of the groove 6 ', turning into a longitudinal guide groove 6.

The walls 4 and 5 of the housing 2 can be made with vertically oriented corrugations 9, while at least one of the walls 4 or 5 of the housing 2 includes at least one through hole such as a loophole 10 or a hole 11, and the edges of the walls 4 or 5 of the housing 2 and / or the edges of their outwardly extending flanges 8 include through holes 12 configured to accommodate a variety of fixing elements (not shown conditionally) such as pins, axles, crutches, threaded rods, bolts, screws, rivets, etc.

In addition, the housing 2 can be equipped with an additional jumper 13 of an arched (curved in radius) convex shape connecting the side ends of the walls 4 and 5 on one side.

The guard includes unit modules 1 interconnected in a chain, which are preferably overlapped and connected by means of articulated rods 14, one end of which is fixed to one unit module 1, and the other is located in the longitudinal groove 6 of the adjacent unit module G with the possibility of displacement from one extreme position to another. The hinge rod 14 includes at least one spherical head 15.

The unit modules 1 are additionally fixed relative to each other and / or the base surface 16, on which they are installed by means of fixing elements (as mentioned above, not shown conditionally) such as pins, axles, crutches, threaded rods, bolts, screws, rivets, etc., placed in the holes 12 at the edges of the walls 4 and / or 5 of the housing 2 and / or at the edges of their flanges 8.

The method of erection (installation) of the fence includes the sequential installation of the previously described individual modules 1 of the fence with its outwardly directed flanges 8 (so-called bases - the same position. 8) on the lower parts of the walls 4 and 5 on the base surface 16, and before installation, single modules 1 fencing sequentially enter one into another and sequentially connected to each other with the possibility of subsequent fixed relative movement by means of longitudinal guide grooves 6 on one unit modules 1 and interact interacting with them with the formation of kinematic pairs of articulated rods 14 mounted on adjacent adjacent unit modules, while the fence modules 1 are placed on a mobile platform 17 and unfold their outward flanges (bases) 8 in the direction of its movement by an angle of not more than 90 °, and the sequential installation of single modules 1 is carried out by dumping outwardly flanging 8 (base) on the base surface 16 of at least the first of them.

As mentioned above, the longitudinal guide grooves 6 of the individual modules 1 are made located on the outside of the walls 4 and 5 of their bodies 2 of the outer side of the jumpers 3.

The turning angle α of the outward-facing flanges 8 of the guard modules 1 to the base of the mobile platform 17 is preferably calculated by the formula:

α = 90 ° -arctg (h / a),

where h is the height of the module fencing;

and - the length of the module fencing.

On the rubbing and contact surfaces of the unit modules included in the enclosure 1, a protective coating with antifriction properties, for example, a lubricant, is preliminarily applied.

The unit modules 1 of the erected fence are fixedly fixed relative to each other and / or the base surface 16 of the above-mentioned locking elements.

The method of dismantling the fences erected in the above-cited way is carried out in the reverse order and consists in sequentially removing from the base surface 16 individual fencing modules 1 and placing them on the mobile platform 17 with one into the other, while the individual modules 1 sequentially fixing relocate relative to each other by longitudinal grooves 6 on one unit modules 1 and interacting articulated rods 14, mounted on adjacent unit modules, by smoothly turning outward flanges 8 of each module towards the movement of the mobile platform 17 at an angle β of not more than 90 ° until they are in full contact.

During the removal of single modules 1, at least a portion of the rubbing and contact surfaces is coated with a protective coating with antifriction properties.

Dismantled (disassembled) fencing is placed on a mobile platform 17 with a turn of outwardly flanging 8 unit modules by an angle α of not more than 90 ° in the direction opposite to the direction of their removal.

Let us analyze the essential features of inventions.

The use in the design of module 1 of a spatially curved solid, preferably metal, thin-walled casing 2 of a wedge-shaped, predominantly Λ-shaped symmetric or asymmetric cross-sectional shape allows for maximum compactness when mating one to another (or one to another) during storage and / or transportation. By the symmetry or asymmetry of the Λ-shaped cross section of the thin-walled body 2, it should be understood the same or different angles of inclination of the walls 4 and 5 of the body 2 relative to the vertical axis (plane) passing through its profile section. In the first case, the vertical axis (plane) in some cases can be considered the axis (plane) of symmetry of module 1.

In its upper part, the housing 2 includes a jumper 3 between the walls 4 and 5, which allows, if necessary, to use at least three conventionally dimensioned, connected, for example, by welding parts instead of one oversized and difficult to bend, which qualifies the design as more technological. The supply of the housing 2 in its upper part from the side of the jumper 3 with a special outwardly directed portion 7 with a longitudinal guide groove 6 (as a rule, straight), including fragmentary sections of 6 ′ entering the jumper 3, provides the possibility of subsequent combination of a number of individual modules 1 into the enclosure according to the principle of a flexible chain - using intermediate parts (articulated rods 14 with spherical 15 and / or cylindrical 18 heads) that provide articulation with the required number of degrees of freedom, including if using special carriages with rolling and sliding bearings (not shown conditionally), but, in addition, such an extra- or large-sized “chain” can be compactly packed with its modules 1 in one another (or one on another) during storage and / or transportation.

The lower parts of the walls 4 and 5 of the unit module 1 are equipped with outwardly directed flanges 8, which serve as its base. Since module 1 can be installed on any surface, it may require the necessary bearing area so that it does not sink under the action of its own, sometimes impressive gravity, which is typical of a steel structure, for example, in soft soil. In addition, it may be necessary to fix the module 1 stationary on the surface, which can be easily done by installing fasteners, such as crutches (not shown conditionally), in the corresponding holes 12 of the flanges 8.

In the case of overall walls 4 and 5, to maintain their rigidity, the strength properties of the material from which they are made may not be sufficient. To eliminate this drawback, the thin walls 4 and 5 of the housing 2 are performed with vertically oriented corrugations 9.

To further improve the strength properties of both a single module 1 and the fence, on its basis, the housing 2 is equipped with an additional jumper 13 of an arcuate (i.e., with curved radius sections) convex (protruding not inside but outside) connecting the side ends walls 4 and 5 on one side. An additional jumper 13 can be made either in the form of a strip, a bar, a profile, etc., or in the form of a body-stamped part calibrating almost the entire profile section of a single module 1 — it all depends on its dimensions — and provides a number of advantages . An additional jumper 13 calibrates the shape of the end face of a single module 1, which is very important for large-sized products from sheet materials. It performs the function of a chamfer when docking with the previous module 1. It fixes the assembled fence in the transverse direction more reliably than the recommended (preferred) overlap of modules 1 against each other. When storing single modules 1 in the form of a vertically standing “tower”, an additional jumper 13 does not allow the walls 4 and 5 of the lower modules to move apart under the action of the gravity of the modules 1 located at the top, while their bulge outward does not prevent the assembly of the modules 1 on top of each other. The overall stability of such a design increases. It is also possible to position the lower boundary of the additional jumper 13 at a level corresponding to the position of a single module 1 before erecting the fence, then the turn of the modules 1 until the additional jumpers 13 come in contact with the base 19 of the mobile platform 17 will allow you to visually monitor compliance with the installation of the fence.

It should be noted that in some cases, additional jumpers 13 due to their design or location may interfere with the movement of people inside the fence or constrain it.

The advantage of manufacturing single modules 1 of metal is that, depending on the conditions of their application and operation, you can choose, for example, titanium, steel or any other alloys. In some cases, modules 1 will be lighter, in others heavier (for example, a steel module measuring 2.5 × 2.5 m and a wall thickness of 4 and 5 - 5 mm will weigh about 500 kg), and fences based on them will for example, lightweight, massive, viscous, durable, heat-conducting, corrosion-resistant, etc. or combine several properties at once.

Already in this form, a single module 1 can be used as an independent product - mini-barriers. Docking (so far without the use of articulated rods 14 and, as a rule, manual) of two or more single modules 1 and their subsequent fixation using a variety of fasteners allows to obtain a more complete and extended fence.

In the case of specialization of fences based on this module 1 as a fortification, walls 4 and 5 of module 1 can be equipped with holes such as loopholes 10 and / or through (through both walls 4 and 5) or one-way (through one wall - or 4, or 5) manhole 11.

The edges of the walls 4 and 5 of the housing 1, like the edges of their outwardly extending flanges 8, can include through holes 12 configured to accommodate various locking elements. This will allow the modules 1 to be fixedly fixed relative to each other, which will make unauthorized dismantling of the fence difficult or allow the fence to more successfully resist the effects of external forces, such as pressure from wind, water, animals, people, tangential impacts of cars, etc.

When forming fencing from interconnected unit modules 1, the latter are preferably overlapped, but this is possible only on a specially prepared even base, avoiding turns, for example, on an area in a settlement, etc. Of course, if the base surface is rugged terrain, then the overlap will be conditional - complete for some modules 1 and partial (only with one wall 4 or 5 or only with the top of case 2) for others. The full or partial overlap of the unit modules 1 is ensured automatically during the installation of the fence due to the correctly selected length of the articulated rods 14, one end of which is fixed to one unit module 1, and the other is located in the longitudinal groove 6 of the adjacent unit module 1 ′ with the possibility of displacement from one extreme position to another. Of course, the thrusts 14 with spherical heads 15 would be the most acceptable constructively, but this will require high precision manufacturing of both the thrusts 14 themselves and the longitudinal grooves 6 (6 ′) for their displacement in modules 1, as well as the organization of special locks for inserting into longitudinal grooves 6 (6 ′). It has been experimentally established that rods 14 with cylindrical heads 18 require less manufacturing precision, locks are not necessary for them to be inserted into grooves 6 (6 ′), and they also provide the necessary rotation of modules 1 relative to each other (the so-called rounding of the fence), which ideally allows you to close the fence and thus localize a limited area.

Due to the presence of rods 14, the fence is a single assembly unit both in the erected state and in the form assembled for storage or transportation.

The unit modules 1 of the erected fence can be additionally fixed relative to each other and / or the base surface 16, on which they are installed by means of fixing elements placed in the holes 12 at the edges of the walls 4 and 5 of the housing 2 and / or at the edges of their outward flanges 8. Fixing carried out regardless of the presence of additional jumpers 13 between the walls 4 and 5 of the housing 2. It should be noted that the holes can be made "in place" - regardless of the degree of overlap of the walls 4 and 5 of the housing 2 and the detected gap falling regular holes 12 with each other, using portable drilling equipment. Thus, the fence becomes non-separable and acquires additional strength properties, which make it an obstacle to a greater extent than just an erected unfixed fence.

A feature of the method of erection (installation) of the fence is that the fence is long (hundreds and thousands of meters) and literally minutes are allotted for its installation. To ensure this, before installing single fencing modules on the base surface, they are preliminarily prepared for installation, for which modules 1 are successively inserted into one another (one on another) and at the same time they connect one module 1 to another (subsequent module 1 ′) using hinged rods 14, thus forming kinematic pairs with the necessary number of degrees of freedom necessary for the maximum possible copying of the terrain (one should not take into account the impossibility of copying a depression, for example, m of radius of radius of module 1, the length of which is, for example, 2.5 m, and the impossibility and inexpediency of enclosing a circle, for example, a lone tree or a private house).

In the assembled (prepared for erection) form, the individual fencing modules 1 are placed on a mobile platform 17, for example, on a KamAZ truck, and are deployed with their outward flanges 8 in the direction of its movement at an angle from 0 ° to 90 °, which corresponds in shape to upright "tower" to the "tower" lying on its side. However, it is preferable to withstand the angle:

α = 90 ° -arctg (h / a),

where h and a respectively the height and length of the module fencing.

Physically, this looks like a perpendicular arrangement of the conditional diagonal of each unit module 1 to the base 19 of the mobile platform 17 (not shown due to obviousness). Modules 1 are interconnected by articulated rods 14 of minimum length. In the assembled, most compact form, the fence can be quickly delivered to the desired geographical point. The sequential installation of single modules 1 from the mobile platform 17 to the base surface 16 is carried out by dumping with little effort, as a rule, by means of mechanization of at least the first or several first modules 1 with their outward flanges (bases) 8 on the base surface 16 , and the remaining modules 1 will automatically slide after the first - one after another. Thus, a conditionally rectilinear fence, for example, 1 km long at a mobile platform speed of 30 km / h, will be erected on average in two minutes with a small one. For a slightly longer time, with a fence of this length, you can fence off a site with a diameter of about 310 m

It should be noted that the fence can be erected in several stages. For example, the fence is placed on several machines and, after the construction of one section, it is connected (due to quick-release articulated rods 14 with heads 15 or 18, for example, on cotter pins) with the next set of the fence located on the second mobile platform 17, which after the connection is operatively throws out "another section of the fence, etc. If necessary, a special service fixes the fence on the base surface 16, and its unit modules 1 - between themselves, or vice versa, the fixation, as mentioned above, can be done despite the presence of additional jumpers 13 between the walls 4 and 5 of the housing 2.

As for the angle of inclination of the flanges 8 to the base 19 of the mobile platform 17 in the region of 0 °, which corresponds to the shape of a vertically standing “tower”, in this case the number of modules 1 in the enclosure is sharply limited, the structural stability is reduced, especially in the initial state, and for installation (erection) of the fence will require a special device such as a vertically movable elongated slice of a special profile, the lowering speed of which will be synchronized with the speed of the platform 17. Also It is advisable to increase the length of the articulated rods 14. In addition, considerable efforts will be required to simultaneously shift the first modules 1 using mechanical means.

As for the angle of inclination of the flanges 8 to the base 19 of the mobile platform 17 in the region of 90 °, which corresponds to the shape of the “tower” lying on its side, this is the most compact in height, stable and roomy view of the future fence. A feature of the design of its modules 1 will be an increased length of the fragment of the groove 6 ', at least on one edge of the jumper 3, which will contribute to a decrease in the strength characteristics of the structure (or uneven strength), and to some extent the increased length of the articulated rod 14, which is necessary for unhindered passage of the “diagonal” of module 1 through the perpendicular to the base 19 of the mobile platform 17. This is a kind of forced payment for the possibility of reorienting the bases of modules 1 (outward flanges 8) to a maximum angle of 90 - translation from transport to working position. This translation is carried out by means of mechanization.

Given the specifics of the first storage, and then the erection of the fence, guarantees are required for the operability of a large-sized structure and the minimization of friction forces of parts. For this, at least on the characteristic rubbing and contact surfaces, a protective coating with antifriction properties is preliminarily applied. The simplest and most affordable form of such a coating is grease.

Depending on the expected operating time of the fence and the need to resist external forces, individual modules 1 can be fixed relative to each other and / or the base surface 16, which will be the result of the construction of the structure in its private form of implementation, and the structure itself will be a fundamental, almost monolithic structure . As a result, you can get the maximum possible positive effect from the use of this technical solution.

The dismantling of the fence erected by the previously mentioned method is carried out in the reverse order of the construction of the fence - unit modules 1 sequentially, starting from the last installed, are removed from the base surface 16 and re-placed on the mobile platform 17 with one in the other. Of course, previously fixed relative to each other and / or the base surface 16, the modules 1 are released from the locking elements. After that, the unit modules 1 are successively fixed relative to each other by means of longitudinal grooves 6 (6 ′) on the same unit modules and the articulated link rods 14 attached to the adjacent unit modules 1, by smoothly turning the outward flanges 8 of each module 1 towards the movement the mobile platform 17 at an angle of no more than 90 ° - until the moment of smooth docking with the previously removed module 1. The dismantled (disassembled) guard is placed on the mobile platform with the final turn outward flanges (bases) of 8 unit modules 1 at a fixed angle of not more than 90 ° in the direction opposite to the direction of their removal. Experience has shown that dismantling a fence duplicates its construction to the exact opposite. For this reason, it will be most optimal to place the removed single modules 1 on the mobile platform 17 at an angle α, corresponding to the perpendicular arrangement of their conditional diagonals to the base 19 of the mobile platform 17. This eliminates spurious movements of the modules 1, and therefore minimizes dismantling efforts.

During the removal of single modules 1, a part of the rubbing and contact surfaces is coated with a protective coating with antifriction properties, for example, grease. This achieves a significant reduction in the friction forces during assembly (as well as subsequent installation) and ensures the conservation of the assembled fence for the entire period of its possible storage.

Dismantling the fence requires more time and considerable effort compared to its construction. However, the use of special means of mechanization can make the dismantling speed quite acceptable, especially since the dismantling speed (time for dismantling) is practically not regulated, with the exception of cases of repeated construction of the fence in a new place.

It should be noted that in some cases the fence cannot be dismantled. This can happen, for example, due to its mechanical damage, thermal deformations, etc., incompatible with the further implementation of the fence of its functional purpose. In this case, the fence is disposed of.

Examples of the use of inventions.

Example 1. The general case.

The fencing module 1 is a maximally unified, typical spatially curved solid, thin-walled metal structure of a wedge-shaped cross-section made according to the first invention of the group.

This module 1 is already ready for use for its intended purpose - it is already the minimum unit of any fence (for example, for organizing a catwalk), and several adjacent unit modules 1, interconnected, for example, with fasteners, are already quite serious a barrier.

However, the main scope of single modules 1 is the organization of prefabricated long fences made according to the second invention of the group. For this, the unit modules 1 are connected together by articulated rods 14, one end of which is able to move in a special longitudinal groove 6, made in the upper part of each adjacent module 1 ′. The most appropriate assembly of the individual modules 1 among themselves by means of articulated rods 14 is carried out in a production environment. In this case, for consumers, it is possible to prepare in advance standardized, for example, by weight or along the length of the future fence, blocks of single modules 1.

Thus, it becomes possible to fold the interconnected modules 1 compactly for storage and / or transportation - you get a super- or just a quick-erectable fence such as a chain, which can subsequently be easily and quickly deployed on the ground.

During storage, the fence can take the form of a vertically standing "tower" to the "tower" lying on its side. The fence should be stored on a special pallet or directly on the mobile platform 17.

To prepare the fence for installation, the individual modules 1 assembled in the “tower” are deployed (or they have already been deployed) with their flanges 8 in the direction of movement of the mobile platform 17 at an angle α, which ensures the sequential removal (sliding) of the individual modules 1 - one after the other. The angle α depends on the length of the articulated rods 14, which should ensure the transition of the conditional diagonal of each unit module 1 through the perpendicular to the base 19 of the mobile platform. With a minimum length of articulated rods 14, the angle α is selected according to the formula given in the present description. It should be noted that in some specially stipulated cases, the angle α can be obtained by turning the modules 1 before the additional jumpers 13 contact between the walls 4 and 5 of the buildings 2 with the base 19 of the mobile platform 17.

Expanded modules are locked for transport.

Upon receipt of instructions for installation of the fence, one or more mobile platforms 17 are advanced to the place of construction, which can be either prepared or unprepared. The preparation may include at least an elementary removal of irregularities in the direction of installation or be a finished area, road, track, etc.

Upon arrival at the beginning of the installation of the fence, the mobile platform 17 is in its original position. Modules 1 are removed from the transport lock. Manually or by means of mechanization, the first unit module 1 is shifted towards the beginning of the installation until it comes into contact with a surface, for example, earth. In this case, the second module 1 ′ will also shift towards the installation side. At a certain moment, the first modules 1 will begin to pull the next one, etc., while the previously installed modules 1 (1 ′) will take their position, which when installed on a flat or convex surface will correspond to their guaranteed overlap or conditional overlap - if copying troughs. If there are additional jumpers 13 between the walls 4 and 5 of the housing 2 of individual modules 1, they will undergo a guaranteed transformation (better and more reliable assembly) into a full fencing.

Depending on the purpose of the installation of the fence, its individual modules 1 can be fixed (fixed) immovably with each other (for example, using fasteners or making one-piece joints) and / or with soil (for example, with clasped or wrapped crutches). A similar result can be obtained by installing the weights on the outwardly flanging 8 lower parts of the walls 4 and 5, for example, concrete blocks.

After the erection of the fence located on the mobile platform 17, you can continue its further installation, for which the last module 1 of the erected fence is connected to the first module 1 of the second row installed on the same mobile platform 17 of the modules 1, or to the first module 1 of the next mobile platform 17 , which replaced the previous one. And so on until the fence is of the required length.

Upon fulfillment by the fence of its purpose, it may be dismantled for disposal or dismantled for subsequent construction. For this, the modules 1 of the fence are freed from the fixing elements, if any have been installed (also destroy welded joints). The mobile platform 17 drives up to the last in the row (by the order of installation) unit module 1 backwards. Using standard means of mechanization, the free end of the “first” module 1 is now torn off the ground and loaded onto the platform 17, which starts moving towards dismantling. Unit modules 1 are forced to sequentially slide relative to each other in the reverse order of the construction process. Grease is applied to the characteristic friction surfaces. Thus, the unit modules 1 connected in a chain are positioned on the base 19 of the platform 17 until a whole series is filled. If necessary, part of the unit modules 1 can be discarded. The remaining modules 1 are again put together in a circuit and the dismantling process continues. The last row module 1 is freed from the articulated link 14 connecting it to the next module 1. In the same way, as far as possible, the filling of the second row of modules 1 on the platform 17 is started. As the mobile platform 17 is filled, it moves off and another platform 17 fits in its place .It also takes away rejected unit modules 1.

When dismantling the guard for disposal, individual modules 1 are freed from the articulated rods 14 and stacked on a platform arbitrarily with a preferred stacking one into another and taken away for processing.

Example 2

When installing this fence according to Example 1 along the highway, it becomes noticeable to reduce the noise level outside the fence. This is facilitated by the double walls of modules 4 and 5 1. There is also a more intensive neutralization of exhaust gases due to their forced swirling by a moving traffic stream.

In the case of prolonged use of such a fence, its individual modules 1 are fixed motionless relative to each other and the ground.

Example 3

When using this fence according to Example 1 for the organization of repair work on the freeway, sections for repair and detour are allocated and, if necessary, marked with markers. A mobile platform 17 with a fence prepared for construction arrives at the repair site and begins to install, for example, the first row of the fence in accordance with the marking markers, reproducing all the technological bends around the repaired area. After installing the first row of fencing of the required length, the modules 1 remaining on the platform 17 are disconnected (the corresponding articulated rod 14 is removed). The platform 17 moves to the installation site of the second row of fencing, which is carried out in a similar way.

Unit modules 1 of both rows are fixed motionless between themselves and relative to the ground. Temporary road markings are applied to the roadway. After the organization of traffic, repair (or restoration) work begins.

Example 4

After the operational installation of this fence according to Example 1 along forest tracts (boundaries of settlements) and grass stand in case of fire of the last wall of 4 or 5 individual modules 1 of the fence, heat shock (flow) will take over and the air gap between walls 4 and 5 will protrude as a reliable thermal insulation layer. As a result, the fire will stop and the fire situation of the fenced forest (settlement) will be under reliable control.

It should be noted that during the enclosure it is necessary to leave specially equipped technological breaks so that at least part of the animals cut off by the fire can escape, while the end sections of modules 1 must be closed for unwanted animals to enter the enclosure. As for passing through technological gaps in the enclosure of flames, they can be extinguished by conventional fire extinguishing means.

Example 5

After the installation of this fence according to Example 1 around a burning peat bog on a previously prepared base (i.e., if possible all irregularities have been removed), individual modules 1 are fixed with a load. Between the first and last unit modules 1 leave a technological gap, which has the ability to be tightly closed.

Carbon dioxide, which is known to be heavier than air, is fed into the cavity of the obtained funnel. Gas fills the funnel and begins to penetrate into the cavity with burning peat, displacing the remaining oxygen from there. Thus, the fire stops. Of course, some of the carbon dioxide will leak through the gaps between the unit modules 1 and the irregularities of the insufficiently prepared base (if these irregularities have not been eliminated separately), but these losses can be neglected.

Example 6

With the operational installation of this fence according to Example 1 along a river floodplain in places with an unstable water level, they are reliably fixed on a previously prepared base, loaded, for example, with concrete blocks and fastened together by each other, the fence modules 1 can withstand water pressure. A certain amount of liquid penetrating into the gaps can be collected in a special cavity, from where it can be easily pumped out using, for example, high-performance axial pumps.

Example 7 - the simplest fortification.

After the operational installation of this fence according to Example 1 around a place occupied by terrorists or destructive elements, double walls 4 and 5 installed at an angle to each other can change the trajectory of flying bullets or significantly extinguish their energy. Due to the decent height of the fence - enough 2-2.5 m - it becomes impossible to aiming stones and other objects, including incendiary mixtures. An angled frontal (with respect to undesirable subjects) wall 4 or 5 of the fence, especially with traces of lubrication on the surface, is a serious obstacle to a single overcoming. It should be noted that on top of the fence you can lay tools that make it difficult to overcome or make it impossible to overcome, such as barbed wire, special tape, etc.

The space between the walls 4 and 5 of the individual modules 1 of the fence can be used to organize inconspicuous movements along its perimeter. In this case, it is appropriate to equip the walls 4 and 5 of the unit modules 1 with openings such as manholes 11 and loopholes 10. This will allow more successfully solving operational and tactical tasks.

Thus, the localization of the dangerous territory will make it possible to more successfully resolve the issues of suppressing unauthorized actions of undesirable entities and their neutralization.

Example 8

Similar to Example 7, adjusted for the use of the erected fence as a stationary demarcation line.

Example 9

The use of one or several unit modules 1 connected to each other and to the ground for organizing fashion shows in characteristic places, such as checkpoints, entrances to the territory of stadiums, landscape territories, etc.

In all of the above cases, the fences are easily dismantled for removal from the place of use for further storage or disposal.

The present examples are not exhaustive to illustrate the uses (or applications) of the inventions. In the same way, technically quite complex devices are presented in the drawings somewhat arbitrarily. For this reason, the features of the invention can be implemented in other versions while maintaining the essence of the above technical solutions.

As a result of the use of the inventions, a fence of virtually unlimited length was created, made on the basis of a universal fence module, simple in design, compact during storage and transportation, possessing, in addition, the tactical and technical characteristics necessary for a simple fortification structure. At the same time, the time for the delivery of the fence to the installation site and its construction was significantly reduced and the time for its dismantling, including the possibility of subsequent operational construction at the new location, was significantly reduced.
