Fire-resistant partitioning element suitable and intended to form a fire separation wall or a fire door leaf installed in a building or a building, leaf or separation wall formed by such an element and fire door comprising at least one such leaf.
[0001 ] (La présente invention concerne le domaine de la protection incendie dans les bâtiments ou les édifices et a pour objet un élément de cloisonnement coupe-feu apte et destiné à former une paroi de séparation coupe-feu ou un battant de porte coupe-feu installé(e) dans un bâtiment ou un édifice. Elle a également pour objet un battant de porte coupe-feu ou une paroi de séparation formé(e) par un tel élément de cloisonnement et une porte coupe-feu comprenant au moins un tel battant. (The present invention relates to the field of fire protection in buildings or buildings and relates to a fire partition element suitable and intended to form a fire separation wall or a shutter door leaf fire installed in a building or edifice.It also relates to a fire door leaf or a partition wall formed by such a partitioning element and a fire door comprising at least one such flying.
[0002] On entendra dans la présente demande par paroi de séparation toute division portante ou non portante séparant deux espaces tels qu’une cloison, un mur, un plancher ou un plafond. [0002] In the present application, the term “separation wall” will be understood to mean any load-bearing or non-load-bearing division separating two spaces such as a partition, a wall, a floor or a ceiling.
[0003] Dans les bâtiments ou les édifices, les éléments de cloisonnement coupe-feu, tels que les parois de séparation ou les portes coupe-feu, permettent de cloisonner le feu pendant une durée temporaire pour lutter contre la propagation d’un incendie et de protéger les matériels et les personnes présentes contre la propagation des flammes, des fumées et/ou des gaz toxiques. [0003] In buildings or buildings, the fire-resistant partitioning elements, such as partition walls or fire doors, allow the fire to be partitioned for a temporary period to fight against the spread of a fire and protect equipment and people present against the spread of flames, smoke and / or toxic gases.
[0004] Une porte coupe-feu peut être simple ou à plusieurs battants et comprend généralement un dormant, également connu sous le nom de cadre dormant, châssis, huisserie ou chambranle, monté rigidement dans une ouverture pratiquée dans une division portante ou non portante et au moins un battant, également connu sous le nom de vantail, maintenu dans/sur le dormant de manière pivotante ou coulissante et des joints d’étanchéité entre le dormant et le ou les battants. [0004] A fire door can be simple or with several leaves and generally comprises a frame, also known as a frame, frame, frame or jamb, rigidly mounted in an opening in a supporting or non-supporting division and at least one leaf, also known as the leaf, held in / on the frame in a pivoting or sliding manner and seals between the frame and the leaf (s).
[0005] Un élément de cloisonnement coupe-feu, plus particulièrement un battant de porte coupe-feu, comprend généralement une coque de protection formée de deux demi-coques assemblées l’une à l’autre en définissant intérieurement un espace interne de remplissage contenant un remplissage coupe-feu comprenant un ou plusieurs matériaux isolants. La coque de protection comprend deux côtés opposés comportant chacun une face externe susceptible, à l’état monté de la porte ou de la paroi de séparation dans un bâtiment ou un édifice, d’être exposée à un incendie se déclenchant dans l’espace correspondant. La coque de protection, habituellement métallique et généralement rigide, usuellement en acier, a pour fonction de protéger le remplissage contre des impacts, chocs, frottements ou dégradations auxquels elle pourrait éventuellement être soumise. Une telle coque de protection peut également former au moins en partie une ossature. A fire partition element, more particularly a fire door leaf, generally comprises a protective shell formed of two half-shells assembled to each other by internally defining an internal filling space containing a fire-resistant filling comprising one or more insulating materials. The protective shell has two sides opposites each comprising an external face capable, in the mounted state of the door or of the partition wall in a building or an edifice, of being exposed to a fire breaking out in the corresponding space. The protective shell, usually metallic and generally rigid, usually made of steel, has the function of protecting the filling against impacts, shocks, friction or damage to which it could possibly be subjected. Such a protective shell can also form at least in part a framework.
[0006] Chaque élément de cloisonnement coupe-feu présente un degré de tenue au feu qui varie en fonction de la nature et l’épaisseur du remplissage. [0006] Each fire-rated partitioning element has a degree of fire resistance which varies depending on the nature and thickness of the filling.
[0007] Toutefois, si les éléments de cloisonnements coupe-feu actuels, plus particulièrement les battants coupe-feu actuels, permettent de répondre aux normes actuelles, ils nécessitent pour les fabricants d’ajuster, à la fabrication, l’épaisseur de la structure de remplissage en fonction du degré coupe-feu souhaité par le client. Pour ce faire, le fabricant doit disposer de matériaux de remplissage coupe-feu et de coques de protection de différentes épaisseurs, ce qui augmente d’autant le coût de la fabrication et du prix de revient des éléments de cloisonnement. [0007] However, if the current fire partition elements, more particularly the current fire doors, make it possible to meet current standards, they require manufacturers to adjust, during manufacture, the thickness of the structure filling according to the fire protection degree desired by the customer. To do this, the manufacturer must have fire-resistant fillers and protective shells of different thicknesses available, which further increases the cost of manufacture and the cost price of the partitioning elements.
[0008] Pour tenter de répondre à ce problème et minimiser les coûts de fabrication, certains fabricants réalisent un ou plusieurs renfoncements dans les faces exposées de la coque de protection en retrait de leur pourtour où la température, en cas d’exposition à des flammes ou gaz chauds, est la plus élevée et où se font généralement les mesures de température pour vérifier la tenue au feu de l’élément de cloisonnement. Ces renfoncements permettent de maintenir l’épaisseur nécessaire de la structure de remplissage au niveau du pourtour et de réduire l’épaisseur de la structure de remplissage au niveau des reliefs créés par les renfoncements dans l’espace interne de remplissage, ce qui économise d’autant de la matière ou du matériau coupe-feu de la structure de remplissage. In an attempt to respond to this problem and minimize manufacturing costs, some manufacturers make one or more recesses in the exposed faces of the protective shell set back from their periphery where the temperature, in the event of exposure to flames or hot gases, is the highest and where the temperature measurements are usually taken to check the fire resistance of the partitioning element. These recesses make it possible to maintain the necessary thickness of the filling structure at the periphery and reduce the thickness of the filling structure at the level of the reliefs created by the recesses in the internal filling space, which saves on as much of the material or the fire-resistant material of the infill structure.
[0009] Toutefois, ces reliefs nécessitent une adaptation de la forme de la structure de remplissage qui complexifie d’autant les opérations de fabrication de l’élément de cloisonnement et ne permet pas de minimiser suffisamment ses coûts de fabrication. [0010] La présente invention a pour but de pallier ces inconvénients en proposant un élément de cloisonnement coupe-feu apte et destiné à former une paroi de séparation ou un battant de porte coupe-feu installé(e) dans un bâtiment ou un édifice, permettant au fabricant de modifier le degré coupe-feu, c’est-à-dire de la tenue au feu de l’élément de cloisonnement, selon les besoins du client, avec un coût réduit, tout en permettant, le cas échéant, une adaptation rapide et simple de la structure de remplissage aux éventuels reliefs s’étendant dans l’espace interne de la coque de protection en vue de minimiser davantage son coût de fabrication. [0009] However, these reliefs require an adaptation of the shape of the filling structure which makes the manufacturing operations of the partitioning element all the more complex and does not make it possible to sufficiently minimize its manufacturing costs. The object of the present invention is to alleviate these drawbacks by providing a fireproof partitioning element capable of and intended to form a partition wall or a fire door leaf installed in a building or a building, allowing the manufacturer to modify the fire resistance degree, that is to say the fire resistance of the partitioning element, according to the customer's needs, with a reduced cost, while allowing, if necessary, a rapid and simple adaptation of the filling structure to any reliefs extending into the internal space of the protective shell with a view to further minimizing its manufacturing cost.

[0024] On entendra plus particulièrement par substances extinctrices : des substances qui peuvent être capables de produire, lors de ladite élévation de température, notamment et par exemple, au moins l’un des effets suivants : [0024] The term “extinguishing substances” will be understood more particularly: substances which may be capable of producing, during said temperature rise, in particular and for example, at least one of the following effects:
[0025] - effet d’absorption de la chaleur, [0025] - heat absorption effect,
[0026] - effet de refroidissement. [0026] - cooling effect.
[0027] De préférence, la ou au moins l’une des substance(s) extinctrice(s) peut consister en de l’eau, de préférence sous une forme liquide, gazeuse telle que de la vapeur d’eau ou solide (glace). Preferably, the or at least one of the extinguishing substance (s) may consist of water, preferably in a liquid, gaseous form such as water vapor or solid (ice ).
[0028] Le produit fonctionnel 3 peut consister préférentiellement en de la colle, de préférence de la colle réfractaire, plus préférentiellement une colle réfractaire à base de silicate, par exemple de la colle réfractaire commercialisée sous la référence « F0142 » par la société Tremco lllbruck SAS, France. The functional product 3 may preferably consist of glue, preferably refractory glue, more preferably a silicate-based refractory glue, for example refractory glue marketed under the reference "F0142" by the company Tremco Illbruck SAS, France.
[0029] Le seuil de température peut être compris de préférence entre 80 et 160 degrés Celsius. [0029] The temperature threshold can preferably be between 80 and 160 degrees Celsius.
[0030] De préférence, le produit fonctionnel 3, tel que de la colle, en vue de permettre son application, peut se présenter sous une forme ou consistance liquide, gélatineuse, pâteuse ou thixotrope. Il peut être appliqué, en une ou plusieurs couches, sur la surface concernée, par exemple par étalement ou pulvérisation grâce à tout moyen tel que, par exemple, un pinceau, une spatule, un pistolet de pulvérisation ou par « gravité ». Preferably, the functional product 3, such as glue, in order to allow its application, may be in a liquid, gelatinous, pasty or thixotropic form or consistency. It can be applied, in one or more layers, to the surface in question, for example by spreading or spraying using any means such as, for example, a brush, a spatula, a spray gun or by “gravity”.
[0031] Toujours conformément à la présente invention, le produit fonctionnel 3 recouvre au moins une partie desdites surfaces interne 10 et externe 40. De préférence ladite partie peut s’étendre parallèlement ou essentiellement parallèlement aux faces exposées 10a, 10b. Still in accordance with the present invention, the functional product 3 covers at least a part of said inner 10 and outer 40 surfaces. Preferably said part can extend parallel or essentially parallel to the exposed faces 10a, 10b.
[0032] De préférence, le ou chaque bloc souple isolant 4 peut être apte à absorber la substance extinctrice, le cas échéant l’eau sous l’une des formes précitées, produite ou libérée par ledit produit fonctionnel 3.

Preferably, the or each flexible insulating block 4 may be able to absorb the extinguishing substance, where appropriate water in one of the aforementioned forms, produced or released by said functional product 3. In addition, the functional product 3 can preferably be a product capable of causing an endothermic reaction, during said temperature rise, to produce or release the extinguishing substance.
[0034] Le ou chaque bloc souple isolant 4 peut consister de préférence en de la laine minérale ou autre matière permettant de limiter la convection et/ou le rayonnement, c’est-à-dire l’élévation de température lorsque l’élément de cloisonnement est exposé aux flammes et/ou aux gaz chauds. En outre la laine minérale permet une bonne absorption de la substance extinctrice telle que de l’eau produite ou libérée par le produit fonctionnel 3 en cas d’élévation de température atteignant ou au-delà de la température seuil, ce qui favorise davantage la tenue au feu. The or each flexible insulating block 4 may preferably consist of mineral wool or other material to limit convection and / or radiation, that is to say the temperature rise when the element of partition is exposed to flames and / or hot gases. In addition, mineral wool allows good absorption of the extinguishing substance such as water produced or released by the functional product 3 in the event of a temperature rise reaching or beyond the threshold temperature, which further favors the resistance. fire.
[0035] Dans une forme de réalisation préférentielle de la coque de protection 1 , comme on peut le voir sur les figures annexées, celle-ci peut comporter deux face internes opposées 1 1 a, 1 1 b, à savoir une première face interne 1 1 a formant la face interne de l’un de ses côtés opposés et une deuxième face interne 1 1 b formant la face interne de l’autre côté opposé, lesdites première et deuxième faces internes 1 1 a, 1 1 b formant une partie de la surface interne 10 de la coque de protection 1 et/ou le ou chaque bloc souple isolant 4 peut comporter deux faces externes 4a, 4b opposées et parallèles auxdites faces internes 1 1 a, 1 1 b, à savoir une première face externe 4a et une deuxième face externe 4b. In a preferred embodiment of the protective shell 1, as can be seen in the appended figures, the latter may have two opposite internal faces 1 1 a, 1 1 b, namely a first internal face 1 1 a forming the inner face of one of its opposite sides and a second inner face 1 1 b forming the inner face of the other opposite side, said first and second inner faces 1 1 a, 1 1 b forming part of the internal surface 10 of the protective shell 1 and / or the or each flexible insulating block 4 may comprise two external faces 4a, 4b opposite and parallel to said internal faces 1 1 a, 1 1 b, namely a first external face 4a and a second external face 4b.
[0036] En outre, le produit fonctionnel 3 peut être appliqué en s’étendant, sur une ou plusieurs couche(s) superposée(s), sur au moins l’une des deux faces internes 1 1 a, 1 1 b opposées de la coque de protection 1 (figures 1 , 2, 4, 5, 6 et 7) et/ou sur au moins l’une des deux faces externes 4a, 4b du ou de chaque bloc souple isolant (4) en étant en contact avec l’une desdites faces internes 1 1 a, 1 1 b (figure 1 ) ou, non représenté sur les figures annexées, à proximité immédiate de cette dernière. In addition, the functional product 3 can be applied by extending, on one or more layer (s) superimposed (s), on at least one of the two internal faces 1 1 a, 1 1 b opposite of the protective shell 1 (Figures 1, 2, 4, 5, 6 and 7) and / or on at least one of the two outer faces 4a, 4b of the or each flexible insulating block (4) while being in contact with one of said internal faces 11a, 11b (Figure 1) or, not shown in the accompanying figures, in close proximity to the latter.
[0037] On comprendra que le contact, ou la proximité immédiate, du produit fonctionnel 3 avec la surface interne 10 de la coque de protection 1 , notamment avec au moins l’une desdites faces internes de ses côtés opposés 1 a, 1 b comportant les faces exposée 10a, 10b, permet un refroidissement plus efficace de la coque de protection 1 en cas d’exposition desdites faces exposées 10a, 10b aux gaz chauds et/ou aux flammes. It will be understood that the contact, or the immediate proximity, of the functional product 3 with the internal surface 10 of the protective shell 1, in particular with at least one of said internal faces of its opposite sides 1 a, 1 b comprising the exposed faces 10a, 10b, allows more efficient cooling of the protective shell 1 in the event of exposure of said exposed faces 10a, 10b to hot gases and / or flames.
[0038] Dans une forme de réalisation préférentielle, la constitution de la coque de protection 1 , celle-ci peut être constituée par l’assemblage entre elles de deux demi-coques 1 a, 1 b, à savoir une première demi-coque 1 a et une deuxième demi-coque 1 b (toutes les figures annexées), de préférence par un assemblage par emboîtement l’une dans l’autre. De préférence, les deux demi-coques 1 a, 1 b présentent une forme sensiblement identique. De préférence, chaque demi- coque 1 a, 1 b peut présenter une section transversale en U. En outre, les dimensions de la deuxième demi-coque 1 b peuvent être prévues pour être inférieures à celles de la première demi-coque 1a de sorte à permettre l’assemblage par emboîtement de la deuxième demi-coque 1 b dans la première demi-coque 1 a (figures 2, 4, 5, 6 et 7). Chaque demi-coque 1 a, 1 b peut comprendre des renforts 8 qui peuvent s’étendre, comme on peut le voir sur la figure 6, dans l’espace interne de la demi-coque 1 a, 1 b correspondante. In a preferred embodiment, the constitution of the protective shell 1, the latter can be constituted by the assembly between them of two half-shells 1 a, 1 b, namely a first half-shell 1 a and a second half-shell 1 b (all the appended figures), preferably by an assembly by fitting one into the other. Preferably, the two half-shells 1 a, 1 b have a substantially identical shape. Preferably, each half-shell 1 a, 1 b may have a U-shaped cross section. In addition, the dimensions of the second half-shell 1 b may be designed to be smaller than those of the first half-shell 1 a so to allow the assembly by fitting of the second half-shell 1b in the first half-shell 1a (Figures 2, 4, 5, 6 and 7). Each half-shell 1 a, 1 b can include reinforcements 8 which can extend, as can be seen in Figure 6, into the internal space of the corresponding half-shell 1 a, 1 b.
[0039] La présente invention peut prévoir d’autres formes d’assemblage, par exemple par rivetage ou vissage. [0039] The present invention may provide other forms of assembly, for example by riveting or screwing.
[0040] La première demi-coque 1 a peut comporter la première face interne 1 1a et la deuxième demi-coque 1 b peut comporter la deuxième face interne 1 1 b (toutes les figures annexées). The first half-shell 1 a may include the first internal face 1 1a and the second half-shell 1 b may include the second internal face 1 1 b (all the accompanying figures).
[0041 ] En fonction de l’application souhaitée, c’est-à-dire selon que l’un des côtés seulement ou les deux côtés opposés 1 a, 1 b de la coque de protection 1 est/sont susceptible(s) d’être exposé(s) à des gaz chauds et/ou des flammes, le produit fonctionnel 3 peut être appliqué, sur une ou plusieurs couche(s) superposée(s) soit sur l’une des faces internes 1 1a, 1 1 b et/ou sur l’une des faces externes 4a, 4b du ou de chaque bloc souple isolant 4, soit sur les deux faces internes 1 1 a, 1 1 b et/ou sur les deux faces externes du ou d’au moins l’un des blocs souples isolant 4. Depending on the desired application, that is to say depending on whether one of the sides only or the two opposite sides 1 a, 1 b of the protective shell 1 is / are likely (s) d 'be exposed to hot gases and / or flames, the functional product 3 can be applied, on one or more superimposed layer (s) or on one of the internal faces 1 1a, 1 1 b and / or on one of the outer faces 4a, 4b of the or each flexible insulating block 4, either on the two inner faces 1 1 a, 1 1 b and / or on the two outer faces of the or at least l one of the flexible insulating blocks 4.
[0042] Si on se réfère aux figures 1 , 2, 4, 5, 6 et 7, on peut voir que le produit fonctionnel 3 peut être appliqué, sur une ou plusieurs couche(s) superposée(s), sur la première face interne 1 1 a et sur la deuxième face interne 1 1 b de la coque de protection 1 de sorte à permettre une protection des deux côtés opposées en cas d’exposition aux gaz chauds et/ou aux flammes d’un côté ou de l’autre de l’élément de cloisonnement 1. If we refer to Figures 1, 2, 4, 5, 6 and 7, we can see that the functional product 3 can be applied, on one or more layer (s) superimposed (s), on the first face internal 1 1 a and on the second internal face 1 1 b of the protective shell 1 so as to allow protection of the two opposite sides in exposure to hot gases and / or flames on either side of the partition 1.
[0043] Si on se réfère à la figure 3, on peut voir que le même effet peut être obtenu en appliquant le produit fonctionnel 3, sur une ou plusieurs couche(s) superposée(s), sur la première face externe 4a et sur la deuxième face externe 4b du ou de chaque bloc souple isolant 4 (figure 3), la structure de remplissage étant configurée pour que le produit 3, à l’état assemblé des demi-coques 1 a, 1 b, soit en contact avec la ou les face(s) interne(s) 10a, 10b ou à proximité immédiate de ces dernières. If we refer to Figure 3, we can see that the same effect can be obtained by applying the functional product 3, on one or more layer (s) superimposed (s), on the first outer face 4a and on the second external face 4b of the or each insulating flexible block 4 (FIG. 3), the filling structure being configured so that the product 3, in the assembled state of the half-shells 1 a, 1 b, is in contact with the or the inner face (s) 10a, 10b or in the immediate vicinity thereof.
[0044] Dans une forme de réalisation non représentée, la ou au moins l’une des couches de produit fonctionnel 3 peut s’étendre entre deux blocs souples isolants 4 adjacents ou superposés. De préférence, la couche de produit fonctionnel 3 peut alors être en contact avec les faces externes correspondantes des deux blocs souples isolants 4. In an embodiment not shown, the or at least one of the layers of functional product 3 may extend between two flexible insulating blocks 4 adjacent or superimposed. Preferably, the functional product layer 3 can then be in contact with the corresponding external faces of the two flexible insulating blocks 4.
[0045] De préférence, comme on peut le voir sur les figures 1 , 2, 3, 4, 5, 6 et 7, le ou chaque bloc souple isolant 4 peut présenter, à l’état non déformé, une forme globalement parallélépipédique rectangle ou tout autre forme permettant une bonne adaptation du bloc souple isolant 4 à l’espace interne de remplissage 2 et en vue d’assurer la protection coupe-feu la plus efficace. Preferably, as can be seen in Figures 1, 2, 3, 4, 5, 6 and 7, the or each flexible insulating block 4 may have, in the undeformed state, a generally rectangular parallelepiped shape or any other shape allowing a good adaptation of the flexible insulating block 4 to the internal filling space 2 and with a view to ensuring the most effective fire protection.
[0046] Si on se réfère aux figures 1 , 2, 3, 4 et 7, on peut voir, dans une première forme de réalisation du nombre de bloc souples isolant 4, que la structure de remplissage 3, 4 peut comprendre un unique bloc souple isolant 4 apte et destiné à occuper (figures 1 et 3) ou occupant (figures 2 et 7) tout ou partiellement ou quasiment tout le volume de l’espace intérieur de remplissage 10 incluant le produit fonctionnel 3 (figures 1 , 2, 3, 7). Dans une forme particulière du bloc souple isolant 4, comme on peut le voir sur la figure 4, celui-ci peut occuper sensiblement la moitié dudit volume. If we refer to Figures 1, 2, 3, 4 and 7, we can see, in a first embodiment of the number of flexible insulating block 4, that the filling structure 3, 4 can include a single block flexible insulating material 4 suitable and intended to occupy (Figures 1 and 3) or occupant (Figures 2 and 7) all or partially or almost the entire volume of the interior filling space 10 including the functional product 3 (Figures 1, 2, 3 , 7). In a particular form of the flexible insulating block 4, as can be seen in FIG. 4, the latter can occupy substantially half of said volume.
[0047] Dans une deuxième forme de réalisation du nombre de bloc souples isolant 4, que la structure de remplissage 3, 4 peut comprendre deux blocs souples isolant 4 superposés ou, comme représenté sur les figures 5 et 6, disposés côte à côte, en étant en contact l’un avec l’autre ou, comme on peut le voir sur ladite figure 6, en laissant un espace entre eux, tout en occupant tout ou partiellement ou quasiment tout le volume de l’espace intérieur de remplissage 10 incluant le produit fonctionnel 3. L’espace laissé entre les deux blocs souples isolant 4 peut être occupé ou défini par un renfort 8, par exemple en forme de paroi, pouvant s’étendre, par exemple depuis l’une des faces internes 1 1 a, 1 1 b, sensiblement perpendiculairement à ses côtés opposés 1 a, 1 b comportant les faces exposées 10a, 10b. On comprend par la disposition, non représentée sur les figures annexées, relative aux deux blocs souples isolant superposés, deux blocs souples isolant dont l’un est situé entre l’autre bloc souple isolant et l’un des deux côtés opposés de la coque de protection 1 . In a second embodiment of the number of flexible insulating block 4, that the filling structure 3, 4 may include two flexible insulating blocks 4 superimposed or, as shown in Figures 5 and 6, arranged side by side, in being in contact with each other or, as can be seen in said figure 6, leaving a space between them, while occupying all or partially or almost the entire volume of the interior filling space 10 including the functional product 3. The space left between the two flexible insulating blocks 4 can be occupied or defined by a reinforcement 8, for example in the form of a wall, which can extend , for example from one of the internal faces 1 1 a, 1 1 b, substantially perpendicular to its opposite sides 1 a, 1 b comprising the exposed faces 10a, 10b. The arrangement, not shown in the appended figures, relating to the two superimposed flexible insulating blocks is understood to mean two flexible insulating blocks, one of which is located between the other flexible insulating block and one of the two opposite sides of the shell. protection 1.
[0048] Si on se réfère maintenant à la figure 7, on peut voir que la coque de protection 1 peut comprendre au moins un renfoncement 5a, 5b pratiqué dans au moins l’une de ses deux faces exposées 11a, 11 b en retrait du pourtour desdites faces exposées 1 1 a, 1 1 b, de préférence dans leur partie médiane ou centrale. Le ou chaque renfoncement externe 5a, 5b s’étend dans l’espace interne de remplissage 2 en créant au moins une cavité 6a, 6b et au moins un relief 7a, 7b dans la surface interne 10, le cas échéant dans la première ou la deuxième face interne 1 1 a, 1 1 b. En outre, la ou au moins l’une desdites cavités 6a, 6b peut être remplie de produit fonctionnel 3 et le produit fonctionnel 3 peut être avantageusement prévu pour ne pas recouvrir le ou chaque relief 7a, 7b ou de le ou les recouvrir uniquement sur une très faible épaisseur, voire une épaisseur quasi nulle ou superflue. Un tel renfoncement 5a, 5b permet ainsi de réduire et d’économiser une quantité substantielle de produit fonctionnel 3 au niveau du ou de chaque relief 7a, 7b s’étendant dans l’espace interne de remplissage en occupant une partie de son volume, tout en maintenant l’épaisseur de produit fonctionnel 3 nécessaire au niveau du pourtour desdites faces exposées 10a, 10b où la température est la plus élevée en cas d’exposition à des flammes ou des gaz chauds. If we now refer to Figure 7, we can see that the protective shell 1 can include at least one recess 5a, 5b made in at least one of its two exposed faces 11a, 11b set back from the periphery of said exposed faces 1 1 a, 1 1 b, preferably in their middle or central part. The or each external recess 5a, 5b extends into the internal filling space 2 by creating at least one cavity 6a, 6b and at least one relief 7a, 7b in the internal surface 10, where appropriate in the first or the first. second internal face 1 1 a, 1 1 b. In addition, the or at least one of said cavities 6a, 6b can be filled with functional product 3 and functional product 3 can be advantageously provided so as not to cover the or each relief 7a, 7b or to cover it or them only on a very small thickness, or even an almost zero or superfluous thickness. Such a recess 5a, 5b thus makes it possible to reduce and save a substantial amount of functional product 3 at the level of the or each relief 7a, 7b extending into the internal filling space while occupying a part of its volume, while by maintaining the thickness of functional product 3 necessary at the level of the periphery of said exposed faces 10a, 10b where the temperature is highest in the event of exposure to flames or hot gases.
[0049] Ainsi, le fabricant, qui veut ajuster le degré coupe-feu de la structure de remplissage 4, selon la présente invention, peut utiliser des bloc(s) souple(s) isolant standards, c’est à dire d’épaisseur constante ou quasi constante, quel que soit la demande d’épaisseur souhaitée de la structure de remplissage 4 et, pour faire varier l’épaisseur, peut ajuster simplement l’épaisseur de la ou des couches de produit fonctionnel 3. En outre, le ou chaque bloc souple isolant 4, par nature déformable, peut-être, si nécessaire, déformé ou comprimé pour s’adapter naturellement, le cas échéant lors de l’assemblage des deux demi-coques 1 a, 1 b, à l’épaisseur de l’espace interne de remplissage 2 défini par la coque de protection utilisée et incluant l’épaisseur désirée de produit fonctionnel 3. Thus, the manufacturer, who wants to adjust the fireproof degree of the filling structure 4, according to the present invention, can use standard flexible block (s) insulating, that is to say of thickness constant or almost constant, regardless of the desired thickness demand of the filling structure 4 and, to vary the thickness, can simply adjust the thickness of the layer or layers of functional product 3. In addition, the or each flexible insulating block 4, by nature deformable, perhaps, if necessary, deformed or compressed to adapt naturally, if necessary during the assembly of the two half-shells 1 a, 1 b, to the thickness of the defined internal filling space 2 by the protective shell used and including the desired thickness of functional product 3.
[0050] La présente invention a également pour objet un battant de porte coupe-feu ou paroi de séparation, non représentés, ledit battant ou ladite paroi de séparation comprenant deux faces externes opposées susceptibles, à l’état installé dans un bâtiment ou édifice, d’être exposé à un feu se déclarant d’un côté ou de l’autre de la porte. The present invention also relates to a fire door leaf or partition wall, not shown, said leaf or said partition wall comprising two opposite external faces likely, in the state installed in a building or building, being exposed to a fire breaking out on either side of the door.
[0051] Conformément à la présente invention, ledit battant ou ladite paroi de séparation est formé(e) à partir d’un élément de cloisonnement tel que défini selon la présente invention et les faces exposées 10a, 10b dudit élément de cloisonnement forment respectivement les faces exposées dudit battant ou de ladite paroi de séparation. According to the present invention, said leaf or said partition wall is formed from a partition element as defined according to the present invention and the exposed faces 10a, 10b of said partition element respectively form the exposed faces of said leaf or said partition wall.
[0052] La présente invention a encore pour objet une porte coupe-feu comprenant au moins un battant et un cadre dormant monté rigidement ou apte et destiné à être monté rigidement dans une ouverture pratiquée dans une paroi telle qu’un mur, un plancher ou un plafond dans un bâtiment ou édifice, ledit battant étant monté dans ou sur ledit dormant, le cas échéant par l’intermédiaire d’un dispositif de liaison tel que des paumelles. The present invention also relates to a fire door comprising at least one leaf and a fixed frame mounted rigidly or suitable and intended to be mounted rigidly in an opening made in a wall such as a wall, a floor or a ceiling in a building or edifice, said leaf being mounted in or on said frame, where appropriate by means of a connecting device such as hinges.
[0053] Dans une telle porte coupe-feu, le ou chaque battant consiste en un battant tel que défini précédemment. In such a fire door, the or each leaf consists of a leaf as defined above.
[0054] Bien entendu, l'invention n'est pas limitée au(x) mode(s) de réalisation décrit(s) et représenté(s) aux dessins annexés. Des modifications restent possibles, notamment du point de vue de la constitution des divers éléments ou par substitution d'équivalents techniques, sans sortir pour autant du domaine de protection de l'invention. Of course, the invention is not limited to the embodiment (s) described and shown in the accompanying drawings. Modifications remain possible, in particular from the point of view of the constitution of the various elements or by substitution of technical equivalents, without thereby departing from the scope of protection of the invention.
