Vehfculo blindado que comprende un tabique cortafuegos.Armored vehicle comprising a firewall partition.
[0001] El campo tecnico de la invencion es el de los vehfculos blindados que comprenden una carrocerfa dentro de la cual se habilitan un compartimento del motor y un habitaculo.[0001] The technical field of the invention is that of armored vehicles comprising a body within which an engine compartment and a room are enabled.
[0002] Habitualmente se preve en tales vehfculos un tabique cortafuegos que permite separar el habitaculo del compartimento del motor.[0002] A firewall is usually provided in such vehicles that allows the room to be separated from the engine compartment.
[0003] Este tabique cortafuegos se extiende asf transversalmente entre dos paredes laterales de la carrocerfa del vehfculo y se extiende tambien verticalmente entre una pared superior y un suelo de la carrocerfa.[0003] This firewall is thus transversely extended between two side walls of the vehicle body and also extends vertically between an upper wall and a floor of the body.
[0004] El tabique cortafuegos tiene como objetivo asegurar una proteccion del habitaculo frente al ruido de la motorizacion.[0004] The firewall is intended to ensure a protection of the room against engine noise.
Este tabique asegura tambien una proteccion termica y permite particularmente proteger el equipo del vehfculo contra incendios potenciales que pudieran declararse a nivel del grupo motopropulsor.This partition also ensures thermal protection and allows the vehicle's equipment to be protected against potential fires that could be declared at the level of the power unit.
[0005] Las patentes FR2864563, CH345567 y US 4693320 describen un tabique cortafuegos conocido.[0005] Patents FR2864563, CH345567 and US 4693320 describe a known firewall partition.
[0006] Los tabiques conocidos tienen la mayorfa de las veces al menos una chapa plana que separa el compartimento del motor y el habitaculo.[0006] The known partitions have most of the times at least one flat plate that separates the engine compartment and the interior.
[0007] Hoy en dfa se intenta aligerar los vehfculos blindados y a la vez mantener un buen nivel de proteccion de la tripulacion contra las minas.[0007] Today, attempts are made to lighten armored vehicles and at the same time maintain a good level of protection of the crew against mines.
Una solucion tradicional consiste en reforzar la proteccion del habitaculo y disminuir la proteccion de las otras partes del vehfculo, en particular la del compartimento del motor.A traditional solution is to strengthen the protection of the room and reduce the protection of other parts of the vehicle, in particular that of the engine compartment.
[0008] Entonces, se presenta el problema de asegurar a nivel del tabique cortafuegos otra funcion que es la proteccion del habitaculo frente a la onda de choque generada por la explosion de una mina bajo el compartimento del motor.[0008] Then, the problem arises of securing at the level of the firewall partition another function that is the protection of the room against the shock wave generated by the explosion of a mine under the engine compartment.
[0009] En efecto, al reducirse la proteccion del compartimento del motor, una parte de la onda de choque generada por la detonacion de una mina se desarrollara en el interior de este compartimento y tendra que ser contenida por el tabique cortafuegos para que no penetre en el habitaculo.[0009] Indeed, when the protection of the engine compartment is reduced, a part of the shock wave generated by the detonation of a mine will develop inside this compartment and will have to be contained by the fire partition so that it does not penetrate In the room.
[0010] Esto lleva a la realizacion de un tabique cortafuegos con un grosor reforzado y, por lo tanto, con una masa aumentada.[0010] This leads to the realization of a firewall with a reinforced thickness and, therefore, with an increased mass.
Ademas, las soldaduras de fijacion del tabique cortafuegos sobre las paredes laterales tambien deben ser reforzadas.In addition, the welding seals of the firewall partition on the side walls must also be reinforced.
[0011] La invencion tiene como objetivo proponer un vehfculo en el cual la proteccion del habitaculo por el tabique cortafuegos es reforzada frente a la onda de choque de las minas sin imponer, no obstante, un aumento del peso de este tabique.[0011] The aim of the invention is to propose a vehicle in which the protection of the room by the fire partition is reinforced against the shock wave of the mines without imposing, however, an increase in the weight of this partition.
[0012] De este modo, la invencion tiene como objeto un vehfculo blindado que comprende una carrocerfa dentro de la cual se habilitan un compartimento del motor y un habitaculo separados el uno del otro por un tabique cortafuegos que se extiende transversalmente entre dos paredes laterales de la carrocerfa del vehfculo y verticalmente entre una pared superior y un suelo de la carrocerfa, vehfculo caracterizado por el hecho de que el tabique cortafuegos esta fijado y asf en apoyo, directa o indirectamente, sobre las paredes laterales por medio de cordones de soldadura y presenta un perfil abovedado cuya convexidad esta orientada hacia el compartimento del motor.[0012] Thus, the invention has as its object an armored vehicle comprising a body within which an engine compartment and a room separated from each other are enabled by a fire partition that extends transversely between two side walls of the vehicle body and vertically between an upper wall and a floor of the body, a vehicle characterized by the fact that the firewall is fixed and thus supporting, directly or indirectly, on the side walls by means of welding cords and presents a vaulted profile whose convexity is oriented towards the engine compartment.
[0013] Segun una forma de realizacion, el tabique cortafuegos tiene un perfil abovedado que se extiende de una pared lateral a otra.[0013] According to one embodiment, the firewall has a vaulted profile that extends from one side wall to another.
[0014] Segun otra forma de realizacion, el tabique cortafuegos incluye una parte central que tiene un perfil abovedado y que se prolonga en ambas partes de la parte central mediante alas planas.[0014] According to another embodiment, the fire partition includes a central part that has a domed profile and is extended in both parts of the central part by means of flat wings.
[0015] Las alas planas podran ser orientadas en la prolongacion de los extremos de la parte central abovedada.[0015] The flat wings may be oriented in the extension of the ends of the domed central part.
[0016] Las alas planas podran estar formadas por placas distintas fijadas a la parte central.[0016] The flat wings may be formed by different plates fixed to the central part.
[0017] Segun otra forma de realizacion, el tabique esta conectado a cada pared mediante un cajon unido mediante soldadura mecanica a una de las paredes laterales.[0017] According to another embodiment, the partition is connected to each wall by a drawer connected by mechanical welding to one of the side walls.
[0018] El vehfculo blindado segun la invencion puede contener una torreta giratoria que esta fijada al nivel de la[0018] The armored vehicle according to the invention may contain a rotating turret that is fixed at the level of the

[0019] El tabique podra ser fijado a la pared superior de la carrocerfa mediante juntas soldadas.[0019] The partition may be fixed to the upper wall of the body by welded joints.
[0020] El tabique podra alojarse en una ranura de la pared superior.[0020] The partition may be housed in a groove in the upper wall.
[0021] El tabique podra estar unido al suelo por medio de un zocalo de apoyo que se fija al suelo y al cual el tabique esta conectado mediante una union cizallable, estando el borde inferior del tabique distanciado del propio suelo.[0021] The partition may be attached to the ground by means of a support socket that is fixed to the ground and to which the partition is connected by a shear joint, the bottom edge of the partition being separated from the floor itself.
[0022] La invencion se comprendera mejor con la lectura de la descripcion siguiente de modos particulares de realizacion, descripcion hecha en referencia a los dibujos anexos y en los cuales:[0022] The invention will be better understood by reading the following description of particular embodiments, description made in reference to the attached drawings and in which:

[0023] En referencia a las figuras 1 y 2, un vehfculo blindado 1 comprende una carrocerfa 2 dentro de la cual se[0023] Referring to Figures 1 and 2, an armored vehicle 1 comprises a body 2 within which

cortafuegos 5.firewall 5.
[0024] Se ha representado en el habitaculo 4 asientos 6 que estan suspendidos de una pared superior 2c (o techo) de la carrocerfa 2.[0024] 4 seats 6 that are suspended from an upper wall 2c (or roof) of the body 2 have been shown in the room.
Tambien se ha representado de manera esquematica en el compartimento del motor 3 un grupo motopropulsor 7 que esta conectado a los medios de movilidad del vehfculo, aquf ruedas 8.Also shown in a schematic manner in the engine compartment 3 is a power unit 7 which is connected to the means of mobility of the vehicle, here wheels 8.
[0025] El tabique cortafuegos 5 se extiende transversalmente entre dos paredes laterales 2a y 2b de la carrocerfa 2 del vehfculo (figura 1) y verticalmente entre la pared superior 2c y un suelo 2d de la carrocerfa.[0025] The fire partition 5 extends transversely between two side walls 2a and 2b of the vehicle body 2 (Figure 1) and vertically between the upper wall 2c and a floor 2d of the body.
Se fija a las diferentes paredes a traves de cordones de soldadura 9.It is fixed to the different walls through weld seams 9.
[0026] Este vehfculo blindado es un vehfculo segun el estado de la tecnica anterior en el cual el tabique cortafuegos 5 esta formado por una placa plana.[0026] This armored vehicle is a vehicle according to the prior art in which the firewall 5 is formed by a flat plate.
[0027] Las figuras 3 y 4 muestran un vehfculo segun una primera forma de realizacion de la invencion.[0027] Figures 3 and 4 show a vehicle according to a first embodiment of the invention.
[0028] Este vehfculo solo difiere del precedente por la forma del tabique cortafuegos 5.[0028] This vehicle differs only from the preceding one by the shape of the fire partition 5.
[0029] Este tabique presenta aquf un perfil abovedado cuya convexidad esta orientada hacia el compartimento del motor 3 y que se extiende de una pared lateral 2a a la otra pared lateral 2b.[0029] This partition presents here a domed profile whose convexity is oriented towards the engine compartment 3 and which extends from a side wall 2a to the other side wall 2b.
[0030] El tabique 5 tiene por lo tanto una cara concava 5a que esta orientada hacia el lado del habitaculo 4 y una cara convexa 5b que esta orientada hacia el compartimento del motor 3.[0030] The partition 5 therefore has a concave face 5a that is oriented towards the side of the room 4 and a convex face 5b that is oriented towards the engine compartment 3.
[0031] El tabique se extiende verticalmente entre la pared superior 2c y el suelo 2d de la carrocerfa.[0031] The partition extends vertically between the upper wall 2c and the floor 2d of the body.
El tabique 5 tambien esta fijado ahf a las diferentes paredes a traves de cordones de soldadura 9.The partition 5 is also fixed there to the different walls through weld seams 9.
[0032] En caso de aparicion de una onda de choque dentro del compartimento del motor 3, onda de choque debida a la explosion de una mina bajo el suelo del compartimento del motor, la forma abovedada del tabique 5 tiene como consecuencia repartir el esfuerzo F axial que resulta de la presion desarrollada dentro del compartimento del motor 3 en esfuerzos F1 y F2 que son tangentes al perfil del tabique 5 al nivel de los bordes laterales de este tabique (bordes en contacto con las paredes laterales 2a y 2b).[0032] In the event of the occurrence of a shock wave inside the engine compartment 3, a shock wave due to the explosion of a mine under the floor of the engine compartment, the vaulted shape of the partition 5 results in the distribution of effort F axial resulting from the pressure developed within the engine compartment 3 in forces F1 and F2 that are tangent to the profile of the partition 5 at the level of the side edges of this partition (edges in contact with the side walls 2a and 2b).
[0033] Al estar el tabique 5 situado en apoyo directamente sobre las paredes laterales 2a, 2b, estos esfuerzos F1 y[0033] Since the partition 5 is located directly on the side walls 2a, 2b, these forces F1 and

F2 son recogidos en parte por las paredes 2a y 2b de la carrocerfa (esfuerzos transversales Fit y F2t).F2 are collected in part by the walls 2a and 2b of the body (transverse forces Fit and F2t).
Los esfuerzos axiales (Fia y F2a) a los que se someten las soldaduras 9 se ven por lo tanto reducidos.The axial stresses (Fia and F2a) to which the welds 9 are subjected are therefore reduced.
[0034] Asf, es por lo tanto posible definir un tabique cortafuegos 5 cuya resistencia mecanica es acrecentada sin que la masa de dicho tabique aumente.[0034] Thus, it is therefore possible to define a fire partition 5 whose mechanical resistance is increased without the mass of said partition increasing.
Es igualmente posible disminuir el grosor del suelo al nivel del compartimento del motor del vehfculo, el tabique cortafuegos 5 asegurando entonces la proteccion del habitaculo 3.It is also possible to reduce the thickness of the floor to the level of the engine compartment of the vehicle, the fire partition 5 then ensuring the protection of the room 3.
El tabique cortafuegos podra ser realizado de acero o de aluminio en funcion de los esfuerzos mecanicos que tenga que resistir.The firewall may be made of steel or aluminum depending on the mechanical stresses that it has to resist.
[0035] Se puede, con un perfil de tabique de seccion circular tal y como esta representado, reducir la masa del tabique alrededor de un 30% con respecto a un tabique plano como se representa en las figuras 1 y 2, aun teniendo una resistencia equivalente a la onda de choque de una mina.[0035] It is possible, with a circular sectional partition profile as shown, to reduce the mass of the partition by about 30% with respect to a flat partition as shown in Figures 1 and 2, even having a resistance equivalent to the shock wave of a mine.
[0036] En el ejemplo representado, el grosor E del tabique 5 es practicamente constante.[0036] In the example shown, the thickness E of the partition 5 is practically constant.
Es claramente posible realizar un tabique cortafuegos 5 cuyo grosor no es constante, por ejemplo un tabique cuyo grosor es creciente entre sus bordes de extremo en contacto con las paredes 2a y 2b y su parte central.It is clearly possible to make a fire partition 5 whose thickness is not constant, for example a partition whose thickness is increasing between its end edges in contact with the walls 2a and 2b and its central part.
Esta solucion es sin embargo menos interesante.This solution is however less interesting.
[0037] El perfil abovedado del tabique 5 es aquf circular en seccion.[0037] The domed profile of partition 5 is here circular in section.
[0038] Es por supuesto posible adoptar para el tabique un perfil que no es circular en seccion, por ejemplo un perfil de seccion elfptica, o un perfil abovedado al nivel de una parte central y prolongado a traves de alas planas en apoyo sobre las paredes laterales.[0038] It is of course possible to adopt for the partition a profile that is not circular in section, for example an elliptical section profile, or a domed profile at the level of a central part and extended through flat wings supporting on the walls lateral.
Una forma de realizacion asf sera descrita despues en referencia a la figura 7.An embodiment will be described later in reference to Figure 7.
[0039] Concretamente, el experto en la materia definira mediante calculo las formas y grosores del tabique cortafuegos 5 en funcion del esfuerzo F maximo al cual el tabique debe resistir y los esfuerzos maximos Fia y F2a que pueden soportar las soldaduras.[0039] Specifically, the person skilled in the art will define by calculation the shapes and thicknesses of the fire partition 5 in function of the maximum effort F to which the partition must resist and the maximum stresses Fia and F2a that the welds can withstand.
[0040] Las figuras 5 y 6 muestran un vehfculo segun otra forma de realizacion de la invencion.[0040] Figures 5 and 6 show a vehicle according to another embodiment of the invention.
[0041] Este vehfculo blindado incluye una torreta pivotante 10 que lleva una arma 11.[0041] This armored vehicle includes a pivoting turret 10 carrying a weapon 11.
La torreta 10 se fija a nivel de la pared superior 2c de la carrocerfa sobre un cojinete circular 12.The turret 10 is fixed at the level of the upper wall 2c of the body on a circular bearing 12.
Solo la rodadura circular 12 esta representada en la figura 5.Only the circular race 12 is shown in figure 5.
Gracias al cojinete 12, la torreta puede girar con respecto a la carrocerfa 2 del vehfculo alrededor de un eje vertical 14.Thanks to the bearing 12, the turret can rotate with respect to the body 2 of the vehicle about a vertical axis 14.
[0042] La torreta 10 lleva una cesta de torreta 13 que esta dispuesta en el habitaculo 4.[0042] Turret 10 carries a turret basket 13 which is arranged in room 4.
[0043] La cesta de torreta 13 se une en rotacion a la torreta 10.[0043] Turret basket 13 is rotatably attached to turret 10.
Esta cesta rodea de una manera tradicional un centro de control del tiro del arma 11 (no representado).This basket traditionally surrounds a gun control center of the gun 11 (not shown).
[0044] Siguiendo esta forma de realizacion, el tabique cortafuegos 5 incluye una parte central que tiene un perfil abovedado y que incluye una cara concava 5a que rodea una parte de la cesta de torreta 13 y una cara convexa 5b dispuesta en el compartimento del motor 3.[0044] Following this embodiment, the fire partition 5 includes a central part that has a domed profile and that includes a concave face 5a that surrounds a part of the turret basket 13 and a convex face 5b arranged in the engine compartment 3.
[0045] El tabique cortafuegos esta conectado a cada pared lateral 2a, 2b por medio de un cajon soldado mecanicamente 15a,15b que esta unido a una de las paredes laterales 2a o 2b.[0045] The fire partition is connected to each side wall 2a, 2b by means of a mechanically welded drawer 15a, 15b which is connected to one of the side walls 2a or 2b.
[0046] Cada cajon soldado mecanicamente 15a,15b esta formado por placas de acero o de aluminio.[0046] Each mechanically welded drawer 15a, 15b consists of steel or aluminum plates.
La estructura de cada cajon esta definida para poder resistir a los esfuerzos F1 y F2 que le seran transmitidos por el tabique 5 como continuacion de la aparicion de una presion en el compartimento del motor 3.The structure of each drawer is defined to be able to resist the forces F1 and F2 that will be transmitted to it by the partition 5 as a continuation of the appearance of a pressure in the engine compartment 3.
[0047] Los cajones 15a y 15b estan igualmente unidos a la parte central del tabique 5 mediante cordones de soldadura 9.[0047] The drawers 15a and 15b are also connected to the central part of the partition 5 by welding cords 9.
Finalmente, los cajones 15a y 15b tambien estan conectados a otros cajones 16a y 16b que se extienden longitudinalmente a las largo de las paredes 2a y 2b del vehfculo.Finally, the drawers 15a and 15b are also connected to other drawers 16a and 16b that extend longitudinally along the walls 2a and 2b of the vehicle.
Estos ultimos cajones son por ejemplo los cajones que cubren las desviaciones de las ruedas 8.These last drawers are for example the drawers that cover the deviations of the wheels 8.
[0048] Como se ve en la figura 5, el perfil en seccion de la parte central del tabique cortafuegos 5 es elfptico.[0048] As seen in Figure 5, the sectional profile of the central part of the firewall 5 is elliptical.
El tabique 5 se encuentra en apoyo sobre las paredes laterales 2a, 2b, de manera indirecta, mediante los cajones 15a y 15b.The partition 5 is supported on the side walls 2a, 2b, indirectly, by means of the drawers 15a and 15b.
[0049] Los puntos de apoyo del tabique 5 sobre los cajones 15a y 15b se situan detras del plano geometrico del eje mayor de esta elipsis.[0049] The support points of the partition 5 on the drawers 15a and 15b are located behind the geometric plane of the major axis of this ellipsis.

Asf, como en la forma de realizacion precedente, la forma abovedada de la parte central del tabique 5 repartira un esfuerzo F axial, resultante de una presion desarrollada dentro del compartimento del motor 3, en esfuerzos F1 y F2 que son tangentes al perfil de la parte central del tabique 5 a nivel de sus bordes de extremo en contacto con los cajones 15a y 15b.Thus, as in the previous embodiment, the vaulted shape of the central part of the partition 5 will distribute an axial force F, resulting from a pressure developed within the engine compartment 3, in forces F1 and F2 that are tangent to the profile of the central part of the partition 5 at the level of its end edges in contact with the drawers 15a and 15b.
[0050] Estos esfuerzos F1 y F2 son recogidos en parte por las paredes 2a y 2b de la carrocerfa a traves de los cajones 15a y 15b.[0050] These efforts F1 and F2 are collected in part by the walls 2a and 2b of the body through the drawers 15a and 15b.
[0051] Los esfuerzos axiales (F1a y F2a) a los que se someten las soldaduras 9 que conectan los cajones 15a, 15b a la carrocerfa 2 son por lo tanto reducidos.[0051] The axial forces (F1a and F2a) to which the welds 9 that connect the drawers 15a, 15b to the body 2 are subjected are therefore reduced.
Ademas, la estructura tabicada de los cajones 15a, 15b permite obtener una resistencia mecanica suficiente con placas de grosor relativamente reducido para realizar los cajones.In addition, the partitioned structure of the drawers 15a, 15b makes it possible to obtain sufficient mechanical strength with plates of relatively reduced thickness to make the drawers.
[0052] Ahf ademas se podra definir un tabique 5 con un grosor no constante o bien un tabique que asocia una parte central concava, de seccion circular o elfptica, prolongada a cada lado mediante alas planas que prolongan la parte central.[0052] In addition, it is possible to define a partition 5 with a non-constant thickness or a partition that associates a concave central part, of circular or elliptical section, extended on each side by means of flat wings that extend the central part.
[0053] Como ejemplo se ha representado asf en la figura 7 un tabique 5 en seccion siguiendo un plano horizontal.[0053] As an example, a partition 5 in section following a horizontal plane has been represented in FIG.
[0054] Este tabique incluye una parte central que tiene un perfil abovedado que comprende una cara convexa 5b dispuesta en el compartimento del motor 3 y una cara concava 5a que rodea parcialmente el cojinete circular 12, por lo tanto la cesta de torreta no es visible en esta figura.[0054] This partition includes a central part having a vaulted profile comprising a convex face 5b disposed in the engine compartment 3 and a concave face 5a partially surrounding the circular bearing 12, therefore the turret basket is not visible in this figure.
[0055] La parte central se prolonga en ambas partes mediante alas planas 5c y 5d que estan fijadas a las paredes laterales 2a y 2b a traves de cordones de soldadura 9.[0055] The central part is extended in both parts by flat wings 5c and 5d that are fixed to the side walls 2a and 2b through weld seams 9.
[0056] En esta forma de realizacion, las alas planas 5c y 5d estan formadas de una sola pieza con la parte central abovedada y estan apoyadas sobre las paredes laterales 2a y 2b.[0056] In this embodiment, the flat wings 5c and 5d are formed in one piece with the domed central part and are supported on the side walls 2a and 2b.
[0057] La parte central tiene aquf una seccion elfptica.[0057] The central part here has an elliptical section.
[0058] Dicho tabique cortafuegos abovedado puede ser facilmente obtenido por plegado (rodaje o tronzado sobre prensa plegadora) de una chapa de acero o de aluminio.[0058] Said vaulted fire partition can be easily obtained by folding (rolling or parting on a folding press) of a sheet of steel or aluminum.
[0059] Otras variantes son posibles sin salir del campo de la invencion.[0059] Other variants are possible without leaving the field of the invention.
Se han descrito previamente tabiques cortafuegos formados por una sola placa abovedada (prolongada o no mediante alas planas).Firewall partitions formed by a single vaulted plate (prolonged or not by means of flat wings) have been previously described.
Es igualmente posible definir un tabique cortafuegos abovedado que comprende varias paredes paralelas las unas a las otras.It is also possible to define a domed firewall partition that comprises several walls parallel to each other.
Este tipo de disposicion permite prever diferentes capas de materiales aislantes termicos o acusticos.This type of arrangement allows to provide different layers of thermal or acoustic insulating materials.
Este tipo de disposicion se describe en la patente FR2864563.This type of arrangement is described in patent FR2864563.
[0060] Con el fin de mejorar la resistencia del tabique 5 a los efectos de una onda de choque de mina, se podra, como se muestra en la figura 8a, alojar el borde superior del tabique 5 en una ranura 17 habilitada en la pared superior 2c.[0060] In order to improve the resistance of the partition 5 to the effects of a mine shock wave, it will be possible, as shown in Figure 8a, to accommodate the upper edge of the partition 5 in a groove 17 enabled in the wall upper 2c.
La ranura tendra por supuesto una forma curva adaptada a la curvatura del tabique 5.The groove will of course have a curved shape adapted to the curvature of the partition 5.
[0061] La pared superior 2c podra estar formada por dos partes 2c1 y 2c2 que comprenden cada una una semiranura 17.[0061] The upper wall 2c may be formed by two parts 2c1 and 2c2 each comprising a semi-groove 17.
Un cordon de soldadura 9 asegurara el enlace de las dos partes del techo 2c y del tabique 5.A welding bead 9 will ensure the connection of the two parts of the roof 2c and the partition 5.
[0062] La ranura 17 procura al tabique 5 un apoyo balfstico.[0062] Slot 17 provides partition 5 with a ballistic support.
Las soldaduras 9 resisten entonces mas facilmente a los esfuerzos F desplegados en el momento de la aparicion de una onda de choque en el compartimento del motor 3.The welds 9 then more easily resist the stresses F deployed at the time of the appearance of a shock wave in the engine compartment 3.
[0063] Segun una forma de realizacion representada en la figura 8b, el tabique 5 se puede unir al suelo 2d por medio de un zocalo de apoyo 18 que esta el mismo fijado al suelo por un cordon de soldadura 9.[0063] According to an embodiment represented in Figure 8b, the partition 5 can be joined to the floor 2d by means of a support socket 18 which is the same fixed to the ground by a welding bead 9.
El tabique 5 esta unido al zocalo 18 mediante una union cizallable (otro cordon de soldadura 9').The partition 5 is connected to the socket 18 by means of a shear joint (another weld bead 9 ').
El borde inferior 19 del tabique 5 esta ademas a una distancia D del propio suelo 2d.The lower edge 19 of the partition 5 is also at a distance D from the floor 2d itself.
Con una estructura asf, una deformacion del suelo 2d (como continuacion, por ejemplo, a la detonacion de una mina bajo el suelo) no impacta en el borde inferior del tabique 5.With such a structure, a deformation of the ground 2d (as a continuation, for example, upon detonation of a mine under the ground) does not impact on the lower edge of the partition 5.
[0064] El tabique se desliza a lo largo del zocalo 18 despues del cizallamiento de la soldadura 9'.[0064] The partition slides along the socket 18 after the shear of the weld 9 '.
Se resalta ademas que el tabique 5 se encuentra en apoyo balfstico contra el zocalo 18.It is also pointed out that partition 5 is in baltic support against socket 18.
Los esfuerzos F que se ejercen sobre el tabique 5 como continuacion de la aparicion de una presion en el compartimento del motor 3 son por lo tanto recogidos por el zocalo 18.The forces F that are exerted on the partition 5 as a continuation of the appearance of a pressure in the engine compartment 3 are therefore picked up by the socket 18.
Este modo de union entre un tabique y un suelo se describe en la solicitud de la patente FR2966231 a la cual se podra referir.This mode of union between a partition and a floor is described in the patent application FR2966231 to which it may refer.
