Abstract

The invention relates to an anti-intrusion wall for protecting the access to a building or part of a building from attacks caused by different means, such as an assault rifle, rotary cutting tools, or explosives. Said wall comprises a plurality of superimposed layers consisting of different materials, especially a fabric consisting of woven filaments for decelerating the degradation caused by rotary cutting tools. The wall also comprises composite panels consisting of a foam core and two outer skins. The judicious combination of the layers considerably increases the amount of time required for the destruction thereof.

Description

« Paroi anti-intrusion »  "Anti-intrusion wall"
Domaine technique Technical area
La présente invention concerne une paroi de sécurité anti-intrusion. The present invention relates to an anti-intrusion security wall.
Ce type de paroi peut être mis en œuvre dans le cadre de sécurisation, notamment dans des établissements comme des banques, des musées, etc. This type of wall can be implemented in the context of security, especially in institutions such as banks, museums, etc.
Etat de la technique antérieure State of the art
On connaît différents dispositifs de sécurité visant à protéger des bâtiments à encontre d'intrusions indésirables. Ces dispositifs sont dits « de dissuasion » car la protection qu'ils fournissent est relative dans le temps et consiste essentiellement à freiner les détériorations afin de bénéficier d'un meilleur délai pour l'intervention des autorités. Various security devices are known to protect buildings against unwanted intrusions. These devices are called "deterrents" because the protection they provide is relative in time and essentially consists of curbing the deteriorations in order to benefit from a better delay for the intervention of the authorities.
Un premier type de paroi de sécurité anti-intrusion, réalisé en béton ou en béton armé, présente l'inconvénient d'être effritable sous l'effet de chocs et de chaleur. Pour être suffisamment protecteur, ce type de paroi doit disposer d'une épaisseur conséquente, ce qui peut s'avérer encombrant et surtout créer une charge supplémentaire sur les fondations de bâtiments qui ne sont pas initialement dimensionnées pour , en particulier si les parois de sécurité doivent être situées à un étage. Ainsi, ajouter des parois de sécurité nécessiterait de renforcer les fondations ou à l'extrême de reconstruire un nouveau bâtiment, ce qui, dans les deux cas, nécessite un budget conséquent. Un second type de paroi de sécurité anti-intrusion, réalisé en métal présente l'inconvénient d'être facilement et rapidement dégradé à l'aide d'outils tels qu'une disqueuse. Ce type de paroi est également lourd et entraîne sur le bâtiment et ses fondations des conséquences similaires à celles engendrées par les parois en béton. A first type of anti-intrusion security wall, made of concrete or reinforced concrete, has the disadvantage of being crumbly under the effect of shock and heat. To be sufficiently protective, this type of wall must have a substantial thickness, which can be cumbersome and especially create an additional load on the foundations of buildings that are not initially sized for, especially if the walls of security must be located on one floor. Thus, adding security walls would require strengthening the foundations or at the extreme of rebuilding a new building, which in both cases requires a substantial budget. A second type of anti-intrusion security wall, made of metal has the disadvantage of being easily and quickly degraded using tools such as a grinder. This type of wall is also heavy and causes the building and its foundations to have consequences similar to those caused by concrete walls.
Il existe des dispositifs antibalistiques constitués d'empilement de couches de différentes ténacités, décrits par exemple dans le WO 2012/150169. Ces parois sont toutefois facilement dégradables avec des outils de découpe, en particulier lorsqu'elles sont fixées sur des murs ou des cloisons. De la même façon, il existe des dispositifs de protection contre l'impact des ondes à forte énergie, constitués d'une superposition de plusieurs couches de , comme décrit dans le WO 2012/128253. Ces dispositifs présentent l'inconvénient similaire aux dispositifs antibalistiques d'être facilement dégradés par des outils de découpe. Anti-ballistic devices consist of stacking layers of different tenacity, described for example in WO 2012/150169. These walls, however, are easily degradable with cutting tools, especially when they are attached to walls or partitions. In the same way, there are protection devices against the impact of high energy waves, consisting of a superposition of several layers of, as described in WO 2012/128253. These devices have the disadvantage similar to antiballistic devices to be easily degraded by cutting tools.
La plupart des parois existantes sont dégradables par l'action d'un outil rotatif de pénétration approprié, tel qu'une perceuse ou une disqueuse. Most existing walls are degradable by the action of a suitable penetrating rotary tool, such as a drill or a grinder.
Le but de la présente invention est de proposer un dispositif remédiant en tout ou partie aux problèmes précédents. The object of the present invention is to provide a device that overcomes all or part of the above problems.
Exposé de l'invention Presentation of the invention
Selon un premier aspect de l'invention, la paroi anti-intrusion comporte une couche de freinage capable de suffisamment freiner un outil rotatif de pénétration pour rendre ce dernier au moins partiellement inopérant. Cette couche est placée derrière une couche d'habillage externe située du côté du risque d'agression. Par outil rotatif de pénétration, on désigne par exemple une perceuse ou une disqueuse. Il a été trouvé qu'une telle couche pourrait être réalisée relativement légère ou même particulièrement légère tout en offrant une résistance nouvelle aux agresseurs et surprenante pour ceux-ci. Une telle paroi peut être utilisée pour sécuriser des lieux pouvant potentiellement être la cible d'attaque, comme un musée, une banque, etc. Elle est idéalement conçue pour résister à des attaq ues notamment par perceuse, d isq ueuse, fusil d 'assaut, lance flamme, explosif, masse,... According to a first aspect of the invention, the anti-intrusion wall comprises a braking layer capable of sufficiently braking a rotary penetration tool to make the latter at least partially inoperative. This layer is placed behind an outer dressing layer on the side of the risk of aggression. For rotary tool penetration, for example means a drill or a grinder. It has been found that such a layer could be made relatively light or even particularly light while offering a new resistance to the aggressors and surprising for them. Such a wall can be used to secure places that could potentially be the target of attack, such as a museum, bank, etc. It is ideally designed to withstand attacks including drill, dice, assault rifle, flamethrower, explosive, mass, ...
Avantageusement, la couche de freinage comprend des filaments q ui par leur nature et leur agencement s'accrochent autour des parties rotatives des outils rotatifs lors d 'une tentative de dég radation . Les filaments entremêlés aux parties rotatives des outils exercent des efforts supplémentaires sur les moteurs des outils, d iminuant leurs capacités ou entraînant des d isfonctionnements. Ainsi, les outils dont la partie rotative est entremêlée ne sont plus en mesure de dég rader la paroi . Les filaments forment la couche de freinage d 'un seul tenant, ce q ui rend d 'autant plus d ifficile et dél icat le dégagement d 'un outil dont la partie rotative est entremêlée dans les filaments q ui ne s'arrachent pas de la couche de freinage. De préférence, les filaments ont une ténacité comprise entre environ 50 cN/tex et environ 350 cN/tex. Advantageously, the braking layer comprises filaments which, by their nature and their arrangement, hang around the rotating parts of the rotary tools during an attempt to disintegrate. The filaments intermingled with the rotating parts of the tools exert additional efforts on the tool motors, imminent their capabilities or causing malfunctions. Thus, the tools whose rotating part is intermingled are no longer able to dislodge the wall. The filaments form the braking layer in one piece, which makes it all the more difficult and difficult to disengage a tool whose rotating part is intermingled in the filaments which do not pull away from the braking layer. Preferably, the filaments have a toughness of from about 50 cN / tex to about 350 cN / tex.
De préférence les filaments ont un allongement à la rupture compris entre environ 3% et environ 6% . Preferably, the filaments have an elongation at break of from about 3% to about 6%.
Avantageusement, le titrage de la couche de freinage est compris entre environ 300 dtex et environ 3300 dtex. Advantageously, the titration of the braking layer is between about 300 dtex and about 3300 dtex.
De préférence, les filaments sont des filaments continus de façon à s'emmêler dans les outils rotatifs et nuire au dégagement des outils. Preferably, the filaments are continuous filaments so as to become entangled in the rotating tools and to hinder the release of the tools.
Avantageusement, les filaments sont en aramide, polyester insaturé ou polyéthylène ; ces matériaux présentant sensiblement les caractéristiq ues précédentes. Advantageously, the filaments are aramid, unsaturated polyester or polyethylene; these materials having substantially the preceding characteristics.
Avantageusement, la couche de freinage est un textile à trois d imensions, en particulier un tissu à trois d imensions. La combinaison des caractéristiq ues citées précédemment est particulièrement efficace contre les agressions par des outils rotatifs. Selon un mode de réalisation avantageux, le duitage de ladite couche de freinage est compris entre environ 30 duites/cm et environ 150 duites/cm. La couche de freinage est typiquement souple et dispose de liberté de mouvement. Ceci rend plus difficile les dégradations de la couche d'habillage externe à l'aide d'outils tels qu'un pied de biche puisque la couche de freinage ne présente pas de surface d'appui suffisamment rigide pour que le pied de biche fasse levier. De plus les extrémités d'un tel outil s'emmêlent dans les filaments, rendant son usage plus difficile. Advantageously, the braking layer is a textile with three dimensions, in particular a fabric with three dimensions. The combination of the features mentioned above is particularly effective against aggression by rotary tools. According to an advantageous embodiment, the debiting of said braking layer is between about 30 picks / cm and about 150 picks / cm. The braking layer is typically flexible and has freedom of movement. This makes it more difficult to degrade the external covering layer by means of tools such as a crowbar since the braking layer does not have a support surface that is rigid enough for the crowbar to pry . In addition, the ends of such a tool get entangled in the filaments, making its use more difficult.
L'épaisseur de la couche de freinage est de préférence comprise entre environ 1mm et environ 5mm. De préférence, la paroi comprend au moins un panneau composite interne, de type sandwich avec une âme en mousse entre deux peaux. Ces panneaux assurent la tenue de la paroi et l'absorption des ondes de chocs causées par des explosifs ou des agressions à la masse. Les peaux solidifient les panneaux et peuvent être réalisées en aramide, verre ou carbone. The thickness of the braking layer is preferably between about 1 mm and about 5 mm. Preferably, the wall comprises at least one internal sandwich-type composite panel with a foam core between two skins. These panels ensure the holding of the wall and the absorption of shock waves caused by explosives or damage to the ground. The skins solidify the panels and can be made of aramid, glass or carbon.
Avantageusement, les deux peaux sont reliées entre elles par des ponts résistant à la traction. Ces ponts donnent une bonne résistance à l'arrachement des peaux, ce qui assure une protection à l'âme en cas de dégradation, notamment tentative d'arrachage et de grattage. Advantageously, the two skins are interconnected by tensile bridges. These bridges give good resistance to the tearing of the skins, which provides protection to the soul in case of degradation, including attempted tearing and scraping.
Avantageusement, l'épaisseur d'un panneau est comprise entre environ 15 mm et environ 40 mm. En cas de découpage à l'aide d'un outil rotatif, l'épaisseur est adaptée pour que la partie rotative de l'outil traverse la couche et s'emmêle dans la couche de freinage située directement derrière, rendant de ce fait l'outil inopérant selon des effets similaires à ceux précédemment cités. Advantageously, the thickness of a panel is between about 15 mm and about 40 mm. In case of cutting with a rotary tool, the thickness is adapted so that the rotating part of the tool passes through the layer and gets tangled in the braking layer directly behind, thereby making it inoperative tool with effects similar to those previously mentioned.
Idéalement, l'au moins une couche de freinage comprend au moins deux couches, et la paroi comprend au moins un panneau, et l'au moins un panneau comprend un panneau séparant les deux couches de freinage, de façon à augmenter la résistance aux agressions. Cette alternance combine avantageusement les propriétés de chaque type de couche afin d'obtenir une paroi résistante aux agressions par les outils décrits précédemment pendant des durées sensiblement égales à trente minutes. Ideally, the at least one braking layer comprises at least two layers, and the wall comprises at least one panel, and the at least one panel includes a panel separating the two layers of braking, so as to increase the resistance to aggression. This alternation advantageously combines the properties of each type of layer to obtain a wall resistant to attack by the tools described above for periods of time substantially equal to thirty minutes.
Selon un mode de réalisation avantageux, l'au moins une couche et l'au moins un panneau sont fixés l'un à l'autre indépendamment de l'habillage externe et peuvent par exemple être fixés ensemble par des moyens mécaniques localisés tels que des boulons traversant. Les fixations sont agencées de façon à laisser suffisamment de libertés aux couches de freinage afin de favoriser l'interaction des filaments dans les outils rotatifs. According to an advantageous embodiment, the at least one layer and the at least one panel are fixed to each other independently of the external covering and may for example be fastened together by localized mechanical means such as through bolts. The fasteners are arranged so as to leave enough freedom for the braking layers to promote the interaction of the filaments in the rotary tools.
Avantageusement, les moyens de fixation contribuent à définir l'épaisseur de la couche de freinage à une valeur choisie suffisamment grande pour favoriser l'interaction des filaments avec les outils rotatifs. Advantageously, the fastening means contribute to defining the thickness of the braking layer at a value chosen large enough to promote the interaction of the filaments with the rotary tools.
Selon un mode de réalisation avantageux, l'habillage externe dissimule les moyens de fixation de l'au moins une couche et de l'au moins un panneau. According to an advantageous embodiment, the outer covering conceals the fastening means of the at least one layer and the at least one panel.
Avantageusement, l'habillage externe est fixé par collage à la couche de freinage sous-jacente afin de posséder un aspect homogène sans système de fixation apparente, comme des boulons par exemple, qui peuvent présenter des faiblesses. Advantageously, the outer covering is fixed by gluing to the underlying braking layer to have a homogeneous appearance without apparent fastening system, such as bolts for example, which may have weaknesses.
De préférence, des jointures entre les éléments constitutifs de l'habillage externe sont décalées par rapport à des jointures sous-jacentes des couches internes afin de limiter une dégradation causée par un outil pouvant ouvrir une brèche, tel un pied de biche. Preferably, joints between the components of the outer covering are offset from underlying joints of the inner layers to limit degradation caused by a breakable tool, such as a crowbar.
Avantageusement, la paroi est constituée de deux couches de freinage séparées par un panneau sensiblement rigide et situées entre l'habillage externe et un habillage interne, de façon à augmenter la résistance aux agressions. L'habillage interne peut être un panneau essentiellement identique au panneau intercalé entre les deux couches de freinage. Avantageusement, la masse surfacique de la paroi est comprise entre environ 25 kg/m2 et environ 35 kg/m2. Elle peut ainsi être mise en place facilement sans ajouter au bâtiment et à son infrastructure une charge exceptionnelle nécessitant des renforcements coûteux et délicats à mettre en œuvre. Advantageously, the wall consists of two braking layers separated by a substantially rigid panel and located between the outer covering and an internal lining, so as to increase the resistance to attack. The inner lining may be a substantially identical panel panel intercalated between the two layers of braking. Advantageously, the surface density of the wall is between about 25 kg / m 2 and about 35 kg / m 2 . It can thus be easily installed without adding to the building and its infrastructure an exceptional load requiring expensive and delicate reinforcements to implement.
Idéalement, l'épaisseur de ladite paroi est comprise entre environ 70 mm et environ 90 mm. Ideally, the thickness of said wall is between about 70 mm and about 90 mm.
Selon un mode de réalisation avantageux, l'habillage externe est un blindage antibalistique offrant une protection face aux agressions aux armes à feux (fusils d'assaut, bazooka,...). According to an advantageous embodiment, the external covering is an anti-ballistic armor providing protection against assault with firearms (assault rifles, bazooka, etc.).

De préférence, la couche souple est placée entre la couche d'habillage externe et un panneau composite, en particulier de type sandwich, de préférence avec des ponts reliant les deux peaux du panneau sandwich, ou avec des fibres partant des peaux et implantées dans l'âme du panneau sans nécessairement rejoindre l'autre peau. Suivant un troisième aspect, l'invention concerne une paroi anti-intrusion comprenant une couche d'habillage externe, présentant de préférence tout ou partie des particularités énoncées ci-dessus à son sujet, placée du côté exposé aux agressions et formée de plaques assemblées entre elles selon des jointures qui sont décalés par rapport à des jointures entre éléments modulaires composant la paroi du côté de la couche d'habillage externe qui est opposé au risque d'agression, ces éléments modulaires ayant chacun tout ou partie des particularités présentées plus haut concernant au moins une couche de freinage d'outil rotatif, une couche souple derrière la couche de garnissage et/ou un panneau composite, notamment de type sandwich.

Description des figures et modes de réalisation Description of the Figures and Embodiments
D'autres particularités et avantages de l'invention apparaîtront à la lecture de la description détaillée de mises en œuvre et de modes de réalisation nullement limitatifs, et des dessins annexés où : Other features and advantages of the invention will appear on reading the detailed description of implementations and non-limiting embodiments, and the accompanying drawings in which:
- la figure 1 illustre un détail d'une vue en coupe de la paroi selon un mode de réalisation, et FIG. 1 illustrates a detail of a sectional view of the wall according to one embodiment, and
- la figure 2 présente l'agencement des différentes couches, notamment le décalage des jointures entre les couches internes et l'habillage externe.  - Figure 2 shows the arrangement of the different layers, including the offset of the joints between the inner layers and the outer shell.
Ces modes de réalisation n'étant nullement limitatifs, on pourra notamment imaginer des variantes de l'invention ne comprenant qu'une sélection de caractéristiques décrites par la suite isolées des autres caractéristiques décrites, si cette sélection de caractéristiques est suffisante pour conférer un avantage technique ou pour différencier l'invention par rapport à l'état de la technique antérieur. Dans un mode de réalisation représenté aux figures 1 et 2, la paroi de sécurité 1 protège une zone 30 à l'égard d'agressions et d'intrusions provenant de l'extérieur 4. These embodiments being in no way limiting, it will be possible to imagine variants of the invention comprising only a selection of characteristics subsequently described isolated from the other characteristics described, if this selection of features is sufficient to confer a technical advantage or to differentiate the invention from the state of the prior art. In an embodiment shown in FIGS. 1 and 2, the security wall 1 protects an area 30 with respect to external aggressions and intrusions 4.
La paroi de sécurité 1 selon l'invention comporte une couche de freinage 2, placée derrière une couche d'habillage externe 3, qui est du côté exposé au risque d'agression 4. La couche de freinage 2 est capable de suffisamment freiner un outil rotatif de pénétration pour rendre ce dernier au moins partiellement inopérant. Par outil rotatif de pénétration, on désigne par exemple une perceuse ou une disqueuse. Le temps nécessaire pour détruire une paroi 1 conforme à l'exemple présenté est supérieur à 30 minutes. The safety wall 1 according to the invention comprises a braking layer 2, placed behind an outer cladding layer 3, which is on the side exposed to the risk of aggression 4. The braking layer 2 is capable of sufficiently braking a tool rotary penetration to make the latter at least partially inoperative. For rotary tool penetration, for example means a drill or a grinder. The time required to destroy a wall 1 according to the example presented is greater than 30 minutes.
La couche de freinage 2 comprend des filaments 5 qui par leur nature et leur agencement s'accrochent autour des outils rotatifs de pénétration en cas d 'intrusion, sans se libérer de la couche de freinage 2. En s'accrochant aux parties rotatives des outils, les filaments 5 entremêlés ou entortillés exercent des efforts supplémentaires sur les moteurs des outils et d im inuent leurs capacités ou entraînent des d isfonctionnement. Ainsi, les outils ne sont plus en mesure de dég rader la paroi 1. Les filaments 5 forment la couche de freinage 2 d 'un seul tenant, ce q ui rend d 'autant plus difficile et dél icat le dégagement d 'un outil dont la partie rotative est entremêlée dans les filaments 5 q ui restent sol idaires de la couche de freinage 2 g râce à leur long ueur et leur ténacité. Autrement d it, les filaments par leur long ueur et leur d isposition peuvent, une fois en prise avec l'outil, être tirés sur une certaine long ueur pour s'entortil ler avec l'outil, puis ensuite résister à ce mouvement par leur liaison avec la couche, et sans se rompre g râce à leur ténacité suffisante. Les filaments 5 ont une ténacité comprise entre environ 50 cN/tex et environ 350 cN/tex afin d 'être à la fois flexibles et résistants. The braking layer 2 comprises filaments 5 which, by their nature and their arrangement, hang around the rotating penetration tools in case In attaching to the rotating parts of the tools, the entangled or entangled filaments 5 exert additional forces on the tool motors and impart their capabilities or cause malfunctions. . Thus, the tools are no longer able to disengage the wall 1. The filaments 5 form the braking layer 2 in one piece, which makes it all the more difficult and difficult the release of a tool whose the rotating part is intermingled in the filaments 5 which remain solids of the braking layer 2 due to their length and toughness. Otherwise, the filaments by their length and their position can, once in engagement with the tool, be pulled over a certain length of time to become wedged with the tool, and then resist this movement by their bond with the layer, and without breaking due to their sufficient tenacity. The filaments have a toughness of from about 50 cN / tex to about 350 cN / tex in order to be both flexible and resistant.
Les filaments 5 ont un allongement à la rupture compris entre environ 3% et environ 6% . The filaments 5 have an elongation at break of from about 3% to about 6%.
Les filaments 5 ont un titrage compris entre environ 300 dtex et 3300 dtex. The filaments 5 have a titration of between about 300 dtex and 3300 dtex.
Les filaments 5 sont des filaments continus de façon à s'emmêler dans les outils rotatifs tout en restant solidaires de la couche de freinage 2. The filaments 5 are continuous filaments so as to become entangled in the rotary tools while remaining integral with the braking layer 2.
Les filaments 5 sont en aramide. The filaments 5 are aramid.
Le d uitage de lad ite couche de freinage 2 est compris entre environ 30 d uites/cm et environ 150 duites/cm . The diameter of the braking layer 2 is between about 30 d / cm and about 150 / cm.
La couche de freinage 2 est un textile tissé selon u n motif organisé à trois d imensions. La couche de freinage 2 est composée desdits filaments et d 'air, elle est extensible et compressible. La densité de la couche de freinage 2 est telle que les filaments 5 sont suffisamment libres pour ne pas être contraints contre les outils rotatifs, ce qui participe à empêcher le découpage ou l'arrachement des filaments 5, et permet l'entortillage et l'entremêlage. L'agencement des filaments est tel qu'au repos les filaments sont sinueux, ce qui leur donne une réserve de longueur pour être tirés par l'outil rotatif avant de commencer à freiner l'outil rotatif. The braking layer 2 is a fabric woven in an organized pattern with three dimensions. The braking layer 2 is composed of said filaments and air, it is extensible and compressible. The density of the braking layer 2 is such that the filaments 5 are free enough not to be forced against the rotating tools, which helps to prevent the cutting or tearing of the filaments 5, and allows the twisting and intermingling. The arrangement of the filaments is such that at rest the filaments are sinuous, which gives them a reserve of length to be pulled by the rotary tool before starting to brake the rotary tool.
La combinaison des caractéristiques des filaments 5 et de la formation de la couche de freinage 2 décrites précédemment nuit aux agressions par des outils rotatifs. The combination of the characteristics of the filaments 5 and the formation of the braking layer 2 described above harms the aggressions by rotary tools.
La couche de freinage 2 constitue en même temps une couche souple, compressible dans le sens de l'épaisseur. Une couche ayant une telle souplesse et placée derrière l'habillage externe 3 relativement rigide rend plus difficile les dégradations de l'habillage externe 3 à l'aide d'outils tels un pied de biche puisqu'elle ne constitue pas une surface d'appui suffisamment ferme pour exercer un levier de type pied de biche qu'un agresseur utiliserait pour arracher l'habillage externe. L'épaisseur de la couche de freinage 2 lorsqu'elle est installée est environ égale à 3mm . The braking layer 2 is at the same time a flexible layer, compressible in the direction of the thickness. A layer having such flexibility and placed behind the relatively rigid outer covering 3 makes it more difficult to degrade the outer covering 3 by means of tools such as a crowbar since it does not constitute a bearing surface. firm enough to exert a crowbar lever that an aggressor would use to tear out the outer covering. The thickness of the braking layer 2 when installed is approximately equal to 3mm.
Selon l'invention, la paroi 1 comprend deux panneaux composites internes 6 et 7, de type sandwich avec une âme en mousse 9 entre deux peaux 10. Ces panneaux 6 et 7 assurent la tenue de la paroi 1 et l'absorption des ondes de chocs causées par des explosifs ou des agressions à la masse. Les peaux 10 solidifient les panneaux et sont de préférence constituées de tissages de fibres d'aramide. Selon l'invention, les deux peaux 10 d'un panneau 6 sont reliées entre elles par des ponts 11 résistant à la traction . Ces ponts 11 donnent une bonne résistance à l'arrachement des peaux 10, ce qui assure une solidité structurelle aux panneaux composites 6. Dans l'exemple, les ponts 11 sont réalisés par repiquage des fibres constituant les peaux 10. L'épaisseur d'un panneau 6 est environ égale à 20mm. En cas de découpage à l'aide d'un outil rotatif, cette épaisseur est adaptée pour que la partie rotative de l'outil traverse l'épaisseur du panneau 6 et s'emmêle dans les filaments 5 de la couche de freinage 8 suivante. According to the invention, the wall 1 comprises two internal composite panels 6 and 7, of sandwich type with a foam core 9 between two skins 10. These panels 6 and 7 ensure the holding of the wall 1 and the absorption of the waves of shocks caused by explosives or mass attacks. The skins 10 solidify the panels and are preferably made of weaves of aramid fibers. According to the invention, the two skins 10 of a panel 6 are interconnected by bridges 11 resistant to traction. These bridges 11 give good resistance to tearing of the skins 10, which provides structural strength to the composite panels 6. In the example, the bridges 11 are made by subculture of the fibers constituting the skins 10. The thickness of a panel 6 is approximately equal to 20mm. In case of cutting with a rotary tool, this thickness is adapted so that the rotating part of the tool passes through the thickness of the panel 6 and is entangled in the filaments 5 of the next braking layer 8.
Selon l'invention, la paroi comprend cinq couches, l'habillage externe antibalistique 3, recouvrant les couches internes 20 comprenant successivement une première couche de freinage 2, un premier panneau sandwich 6, une deuxième couche de freinage 8 et un deuxième panneau sandwich 7, celui-ci correspondant à l'habillage interne. Il a été trouvé qu'une paroi ainsi conçue pouvait résister jusqu'à trente minutes à une tentative d'intrusion par des personnes bien équipées. Les couches internes 20 sont fixées ensemble indépendamment de l'habillage externe 3 par des boulons 12 traversants. Ces boulons 12 sont disposés horizontalement à la partie supérieure des couches internes 20 afin de laisser des degrés de libertés aux couches de freinage 2 et 8 et favoriser l'entremêlement des filaments 5 dans les outils rotatifs. Les boulons 12 sont équidistants d'environ lm. According to the invention, the wall comprises five layers, the anti-ballistic outer covering 3 covering the inner layers 20 successively comprising a first braking layer 2, a first sandwich panel 6, a second braking layer 8 and a second sandwich panel 7 , this one corresponding to the internal dressing. It was found that a wall thus designed could withstand up to thirty minutes an intrusion attempt by well-equipped people. The inner layers 20 are fixed together independently of the outer skin 3 by bolts 12 through. These bolts 12 are arranged horizontally at the top of the inner layers 20 to allow degrees of freedom to the braking layers 2 and 8 and to promote the intermingling of the filaments 5 in the rotary tools. The bolts 12 are equidistant from about 1m.
Les boulons 12 contribuent à définir l'épaisseur des couches de freinage 2 et 8 à une valeur choisie suffisamment grande pour favoriser l'interaction des filaments 5 avec un outil rotatif de pénétration . The bolts 12 contribute to defining the thickness of the braking layers 2 and 8 at a value chosen large enough to promote the interaction of the filaments 5 with a rotary penetration tool.
L'habillage externe 3 est fixé par collage à la première couche de freinage 2 afin de présenter un aspect homogène et dissimuler les boulons 12 de fixation des couches internes 20. Les jointures 13 entre les éléments constitutifs de l'habillage externe 3 sont décalées par rapport aux jointures 14 sous-jacentes des couches internes 20 afin qu'une attaque de la paroi au niveau d'une jointure 13 ne donne pas directement accès à une jointure 14 et ne permette pas de savoir où se trouve une jointure 14. Dans l'exemple, les jointures 13 et 14 sont verticales. La masse surfacique de la paroi 1 est sensiblement égale à 30kg/m2. La paroi 1 peut ainsi être installée facilement sans que cela surcharge le bâtiment et/ou sa structure, donc sans nécessiter des renforcements coûteux et délicats à mettre en œuvre. The external covering 3 is fixed by gluing to the first braking layer 2 in order to have a homogeneous appearance and to conceal the bolts 12 for fixing the inner layers 20. The seams 13 between the elements constituting the outer covering 3 are offset by relative to the underlying joints 14 of the inner layers 20 so that an attack of the wall at a seam 13 does not give direct access to a seam 14 and does not allow to know where is a seam 14. In the for example, the seams 13 and 14 are vertical. The density of the wall 1 is substantially equal to 30 kg / m 2 . The wall 1 can thus be installed easily without overloading the building and / or its structure, thus without requiring expensive and delicate reinforcements to implement.
L'épaisseur de la paroi 1 est sensiblement égale à 80mm. The thickness of the wall 1 is substantially equal to 80 mm.
L'habillage externe 3 est un blindage antibalistique offrant une protection face aux agressions aux armes à feux (fusils d'assaut, bazooka,...). The external cladding 3 is an anti-ballistic armor offering protection against assault with firearms (assault rifles, bazooka, ...).
L'ensemble des matériaux constituant la paroi 1 subit un traitement ignifugeant. La mise en place de la paroi 1 s'effectue en plusieurs étapes : All materials constituting the wall 1 undergoes fireproofing treatment. The installation of the wall 1 is carried out in several stages:
Premièrement, les couches internes 20 sont fixées sur un mur existant ou des rails par un dispositif de boulons 12. Ensuite, la couche d'habillage antibalistique 3 est collée sur la surface externe des couches internes 20 de façon à ce que les jointures 14 des couches internes 20 et les jointures 13 de la couche d'habillage antibalistique 3 soient décalées.  Firstly, the inner layers 20 are fixed on an existing wall or rails by a bolt device 12. Next, the anti-ballistic coating layer 3 is adhered to the outer surface of the inner layers 20 so that the joints 14 of the inner layers 20 and the joints 13 of the antiballistic coating layer 3 are shifted.
