DESCRIPTION

SHELTER PANELING SYSTEM S-788/G

OBJECT OF THE INVENTION

The present invention refers to the paneling system by which the panels that define the S-788/G shelter are configured and the way these panels are joined, providing it with high tensile strength and withstanding extreme environmental conditions.

TECHNICAL PROBLEM TO SOLVE AND BACKGROUND OF THE INVENTION

As a reference to the current state of the art, it should be noted that there is currently a wide variety of types of shelters based on containers, tanks or wagons that are mainly composed of a rigid structure that is not removable or deployable. These shelters are usually standardized or categorized according to their size, geometry, composition of materials that form them or according to the purpose for which they have been configured.

One of these shelters commonly known in the market is the so-called "Shelter 788/G” which is very widespread in the market since it is widely used by security and rescue teams or members as well as by military groups around the world.

This container element or shelter shelter S-788/G can range from a simple structure of profiles and enclosures to complex watertight shelters, with hermetic gates, ventilation systems, or electronic equipment inside that allow work to be carried out for military or rescue purposes. .

One of the main advantages of this type of shelter container elements is the possibility of being transported by light vehicles, especially by vans or trucks, which allows these shelters to be placed in any place accessible by this type of transport. In fact, the design and configuration of the S-788/G shelter are intended to fit the load carrier of a truck or van.

On the other hand, a common way of transporting the vehicle with the S-788/G shelter already installed is by lifting it with a helicopter, which affects the resistance that the enclosure panels of the S-788/G shelter itself must withstand in yes, since They are normally only considered to withstand environmental conditions and are not oversized to support the weight of the vehicle on which they are mounted.

The present invention comes to solve these problems that were not resolved in the present state of the art by disclosing a panel used in the S-788/G shelter that is not only focused on withstanding adverse environmental conditions, but also a high load structural.

DESCRIPTION OF THE INVENTION

In order to achieve the objectives and avoid the drawbacks mentioned above, the present invention describes a paneling system for the S-788/G shelter. The system comprises side panels (1), a roof panel (2) and a floor panel (3) and the form of connection between them.

On the one hand, the panels are shaped in such a way that they comprise two aluminum sheets, a tubular structure joined to the two aluminum sheets, a central core that fills the space between the two aluminum sheets, and a wooden strip attached to a of aluminum sheets.

The wooden strip has the function of breaking the thermal bridge of the panel.

On the other hand, the joint between two adjacent panels comprises an exterior perimeter corner, an interior perimeter corner, and a sealing putty along the edges of the exterior perimeter corners to the panels to waterproof the interior of the shelter.

Keep in mind that the corner pieces are attached to the panels along the entire length by means of rivets. To prevent the waterproofing of the corners to the panels from failing, the rivets incorporate a crown of sealing putty (9) and thus also achieve waterproofing through this joint.

The tubular structure is joined to the two aluminum sheets by gluing with a two-component epoxy structural adhesive, in order to avoid delamination.

The sealing putty is preferably polyurethane mastic.

The central core is preferably made of self-extinguishing polyurethane without absorbing water or water vapor and is configured to withstand high thermal shocks without undergoing deformation.

The ceiling panel preferably comprises a non-slip surface, comprising a mixture of paint with quartz sand.

The roof panel may also comprise a reinforcing plate for reinforcing the structure of the roof panel.

The ceiling panel can also include non-slip strips made of tear-shaped sheet metal that make up a corridor.

DESCRIPTION OF A PREFERRED EMBODIMENT OF THE INVENTION

The panels (1, 2, 3) that form the shelter of the present invention configure both the side panels (1), including both the front panel and the rear panel, the roof panel (2), the floor panel (3 ) and even doors. A representation can be seen in Figure 3.

Figure 5 represents a section of a panel (1, 2, 3) where it can be seen that the panels (1, 2, 3) have a sandwich-type configuration with a total thickness of 53 mm and are made up of the following elements:

- two aluminum sheets (10), preferably 1.5 mm thick;

- a tubular structure (4), located between the two aluminum sheets (10) and glued to them with a two-component epoxy structural adhesive, preventing delaminations. The gluing is done by press with hot plates. This system prevents the formation of air bubbles, allowing the shelter to be transported by air in non-pressurized cabins. The tubular structure (4), for its part, is not uniform but varies depending on the position it occupies in the shelter;

- a central core (11) of self-extinguishing polyurethane, located between the two aluminum sheets (10) and covering the tubular structure (4), with insignificant absorption of water or water vapour, capable of withstanding high thermal shocks without suffering deformations or degradation of its characteristics; and

- a wooden strip (12), on the outside of the shelter, between the tubular structure (4) and the aluminum sheet (10) intended to be located outside, in order to break the thermal bridge and achieve a global heat transfer coefficient less than or equal to 1.7 W/0C.m2.

Additionally, the system for configuring the complete paneling uses profiles or perimeter corners (13, 14) to carry out the union between two adjacent panels (1, 2, 3) and thus form the enclosure and the formation of the shelter. The corners (13, 14) join the panels both internally and externally, so they differ in internal perimeter corners (13) and external perimeter corners (14). Figure 6 represents corner pieces (13, 14) coupled to join two side panels (1).

The panels (1, 2, 3) are basically the same, except for the roof panel (2). It must be taken into account that the roof of the shelter is a surface that is widely used in operations, so that it is used by a user as a base on which to carry out activities. In this way, in addition to being configured in the usual way, like a side panel (1), the roof panel (2) of the shelter has a series of additional structural components that provide it with the additional rigidity it needs for other situations. where extra effort is required. Figure 4 shows a view of a ceiling panel (2).

The first of these additional structural components is a reinforcement plate (5), made of aluminum alloy, with the aim of protecting this area from possible blows during the shelter's lifting and transport operations.

Additionally, the outer surface of the roof panel (2) incorporates non-slip surfaces (6) to prevent possible slips or falls when accessing the roof. These non-slip surfaces (6) are painted with a mixture of quartz sand paint.

In addition, a preferred option is that the ceiling panel (2) also incorporates an operating corridor, that is, a corridor formed by different non-slip strips (7) made of tear plate. These bands (7) are riveted to the roof panel (2) of the shelter, forming the aforementioned operating corridor, which is also a security one, since its objective is to protect the rest of the roof of the shelter. The need to incorporate an operating corridor is due to the fact that the panels (1, 2, 3) are made of aluminum and have limited resistance. In this way, the roof panel (2) is provided with more adherence and resistance to user operations on the roof of the shelter.

Both the side panels (1) and the roof panel (2) of the shelter incorporate a series of “C” rails (8) in the interior area, so called due to their configuration, intended to fasten the interior equipment. These "C" rails (8) also provide additional structural rigidity to the panels (1, 2, 3). Figure 7 represents a section of a "C" rail (8).

In addition to the requirements to ensure watertightness, the shelter has another series of requirements in terms of environmental characteristics, such as, especially, in terms of resistance to attack by corrosion, by the formation of mold and by a saline environment, so that the different components that can be affected incorporate appropriate treatments.

On the other hand, in order to achieve the impermeability of the shelter, the assembly of the panels (1,2, 3) is carried out as described below:

- Initially, the panels (1, 2, 3) of the shelter are built separately, that is, the four side panels (1), including the front and rear panels, the roof panel (2) and the floor panel ( 3).

- Subsequently, all of them are assembled together using the perimeter corners (13, 14) that join adjacent panels (1, 2, 3) along the entire perimeter line of union.

- Once the panels (1, 2, 3) have been assembled with the perimeter corners (13, 14), all these elements are joined by means of stable, watertight, blind-headed alloy rivets, of the TB 4x9 type .4 and TB 4x7.9.

- Once the joining process of the panels (1, 2, 3) with the perimeter corners (13, 14) by the riveting procedure is finished, a sealing putty (9) is applied along each and every one of the edges that make up the shelter at the junction of the panels with the outer perimeter corners (14).

To proceed to seal the panels (1, 2, 3) with the outer perimeter corners (14), the sealing putty (9) that is applied is preferably polyurethane mastic, a one-component polyurethane putty that cures quickly on contact with the humidity of the atmosphere, forming a hard and elastic sealant used for sealing both joints.

In the same way, the rivets, which are also required to be watertight and with blind heads in order to prevent and ensure the watertightness of the shelter against rain and wading (waterproofing), before placing them and being riveted, They are also impregnated with the sealing putty (9), in order to avoid, with full guarantees, the entry of water or humidity through that hole. In this case it is also preferred that the sealing mastic (9) be polyurethane mastic.

Once the polyurethane mastic is added, the product expands on each edge or groove where there is a possibility of water or humidity entering, achieving a high level of watertightness of the shelter against rain and wading.

On the other hand, to guarantee that the absence of water ingress occurs throughout the useful life of the shelter, the following measures are adopted, differentiated according to the joining elements.

First, the joints in the side panels (1) are considered. The non-ingress of water between the side panel (1) and the outer perimeter corners (14) is guaranteed by sealing with polyurethane mastic capable of guaranteeing its perfect function in situations of extreme operation.

Second, the joints in the roof panel (2) are considered. To ensure that water does not penetrate the roof panel (2), a system has been created that prevents water from stagnating both on the roof surface and on the side panels, between the sandwich panel and the outer perimeter corners (14 ) the joint is sealed with the sealing mastic (9), a polyurethane-based material being preferred and, in particular, polyurethane mastic.

Thirdly, the rivets are considered, which are configured with a crown of the same polyurethane mastic around its head, which prevents the penetration of water once coupled. In addition, the rivets are blind-headed as mentioned above.

Finally, it is also necessary to take into account the openings of doors, gates, energy and signal panels and other elements in contact with the outside. In these cases, to guarantee the non-ingress of water, suitable environmental gaskets are used.

Finally, it must be considered that the present invention should not be limited to the embodiment described here. Other configurations can be made by those skilled in the art in view of the present description. Accordingly, the scope of the invention is defined by the following claims.
