Description

La présente invention porte sur les déflecteurs de protection de pieds de structure pour lesquels le présent inventeur a déjà déposé une première demande de brevet le 06 mars 2013 sous le n° de publication FR 3002 927 , qui est l'état de la technique le plus proche de l'objet de la revendication 1, et n° d'enregistrement national FR 13 00492 , et dont la description de la ci-présente nouvelle demande de brevet en constitue un « perfectionnement ».The present invention relates to structure foot protection deflectors for which the present inventor has already filed a first patent application on March 6, 2013 under the publication number FR 3002 927 , which is the state of the art closest to the subject matter of claim 1, and national registration number FR 13 00492 , and of which the description of the present new patent application constitutes an "improvement" thereof.

Le domaine technique de l'invention est la construction de structures tels que, suivant l'application principale de l'invention, les réservoirs de stockage.The technical field of the invention is the construction of structures such as, according to the main application of the invention, storage tanks.

Les réservoirs de stockage ou plus communément appelés « bacs » sont généralement utilisés pour stocker des produits tel que le pétrole et ces dérivés; des acides, de l'eau, etc....Storage tanks or more commonly called "tanks" are generally used to store products such as oil and its derivatives; acids, water, etc.

Les réservoirs de stockage sont généralement construits en acier carbone et sont sujets à des corrosions externes situées en pied de bac (voir figure 2), aux droits des soudures d'angles de liaison de la virole inférieure (14) et de la bordure annulaire, sous la tôle marginale (15).Storage tanks are generally made of carbon steel and are subject to external corrosion located at the bottom of the tank (see figure 2 ), to the rights of the connection fillet welds of the lower shroud (14) and of the annular edge, under the marginal plate (15).

L'ensemble du bac est posé, sur une galette constituée de couches multiples, un remblai (22) compacté recouvert d'une membrane étanche (20), qui elle-même est recouverte d'un sable bitumineux (21), l'ensemble est entouré d'un anneau béton (23), voire posé sur une galette béton complète ou peut encore être installé sur la cuvette de rétention bétonnée.The entire tank is placed on a slab consisting of multiple layers, a compacted backfill (22) covered with a waterproof membrane (20), which itself is covered with bituminous sand (21), the whole is surrounded by a concrete ring (23), even placed on a complete concrete slab or can still be installed on the concrete retention basin.

Enfin, repose sur cet ensemble support, les tôles de fond du réservoir soudées aux tôles marginales et viroles du réservoir qui permettent de contenir le produit à l'intérieur du bac.Finally, rests on this support assembly, the bottom plates of the tank welded to the marginal plates and shells of the tank which make it possible to contain the product inside the tank.

Ces réservoirs peuvent mesurés en France jusqu'à quatre-vingt-dix mètres de diamètre et d'une hauteur pouvant atteindre une vingtaine de mètres.These reservoirs can be measured in France up to ninety meters in diameter and a height of up to twenty meters.

Les réservoirs en acier inoxydable ne sont pas corrodables mais leurs supports béton peuvent également être endommagés et, sont par conséquent concernés par le matériel présentement désigné. Ils sont également sujets aux fatigues citées ci-dessous.Stainless steel tanks are not corrodible but their concrete supports can also be damaged and are therefore covered by the material presently designated. They are also subject to the fatigues mentioned below.

D'autres éléments sont à prendre en considération concernant les pertes de confinement d'un bac de stockage. Les cycles de chargements/déchargements qui sont des facteurs de fragilisation des liaisons soudées. Ces fragilisations peuvent aboutir à la rupture du fond de bac et ainsi générer une fuite décelable par l'extérieur du réservoir.Other elements are to be taken into consideration concerning the losses of containment of a storage tank. The loading/unloading cycles which are factors of embrittlement of the welded connections. These embrittlements can lead to the rupture of the bottom of the tank and thus generate a detectable leak from the outside of the tank.

Il peut exister à ce jour des déflecteurs fixes qui servent à dévier les eaux de pluies ou encore l'eau d'incendie, lors des tests en réel, effectués par les pompiers et par conséquent, de protéger les structures.There may currently exist fixed deflectors which are used to deflect rainwater or even fire water, during real tests, carried out by firefighters and therefore to protect structures.

Les constructeurs de bacs n'intègrent pas en général la pose de déflecteur sur les pieds de bacs qui se trouve être un accessoire et non pas un élément structurel de bac.Bin manufacturers do not generally include the installation of a deflector on the feet of the bins, which happens to be an accessory and not a structural element of the bin.

Seuls les services qualité, corrosion, inspection, recommandent la mise en place de cette protection, afin de préserver l'intégrité du bac.Only the quality, corrosion and inspection departments recommend the installation of this protection, in order to preserve the integrity of the tank.

Le domaine d'utilisation principal du déflecteur, appelé communément «bavette», se situe sur l'ensemble des réservoirs de stockage, quelques soient leurs utilisations ou la qualité du produit stocké.The main field of use of the deflector, commonly called "flap", is on all storage tanks, whatever their uses or the quality of the stored product.

L'utilisation de cette protection ne se limite pas au stockage pétrolier mais à toutes structures nécessitant le besoin du maintien de l'intégrité.The use of this protection is not limited to oil storage but to all structures requiring the need to maintain integrity.

La plupart des réservoirs ne sont pas équipés de déflecteur, d'autres sont équipés mais d'une manière définitive par des tôles en acier fixes, soudées sur les premières viroles au pied du bac, ce qui empêche tous contrôles automatisés en dessous du déflecteur et ne facilite pas l'examen visuel du pied de structure.Most of the tanks are not equipped with a deflector, others are equipped but permanently with fixed steel sheets, welded to the first rings at the bottom of the tank, which prevents any automated checks below the deflector and does not facilitate the visual examination of the foot of the structure.

L'installation de ces protections est très contraignante et, est réalisée généralement lors de la construction du bac ou bien lors des visites décennales ou encore lors d'arrêt d'opportunité, permettant ainsi le soudage des supports du déflecteur.The installation of these protections is very constraining and is generally carried out during the construction of the tank or during the ten-year inspections or even during stoppages of opportunity, thus allowing the welding of the supports of the deflector.

En effet, aucun travail« à chaud», par soudage en exemple, ne doit être réalisé pendant l'utilisation d'un bac de stockage.Indeed, no “hot” work, by welding for example, must be carried out during the use of a storage tank.

D'autres méthodes de protection, autre que la bavette soudée, sont proposées telles l'application d'un revêtement bitumineux avec un support aluminium ou encore des revêtements époxy, ou même voire des recommandations de codes de construction, proposant la pose d'un déflecteur en bordure de tôle marginale mais, toutes ces propositions ne permettent pas l'inspection des zones sujettes aux dégradations et, et ne peut aboutir à des constatations d'une éventuelle fuite provenant du fond de bac.Other methods of protection, other than the welded flap, are proposed such as the application of a bituminous coating with an aluminum support or even epoxy coatings, or even even building code recommendations, proposing the installation of a deflector on the edge of the marginal plate, but all these proposals do not allow the inspection of the areas subject to damage and, and cannot lead to findings of a possible leak from the bottom of the tank.

En effet, les conditions minimales d'installation de ces déflecteurs doivent respecter les besoins suivants :

  • protéger le pied de bac en évitant la migration de l'eau de pluie sous la tôle marginale.
  • permettre l'inspection et contrôles du pied de bac.
  • laisser une ventilation naturelle suffisante à l'assèchement de la zone.
In fact, the minimum installation conditions for these deflectors must meet the following requirements:
  • protect the foot of the tank by preventing the migration of rainwater under the marginal sheet.
  • allow inspection and checks of the foot of the tank.
  • allow sufficient natural ventilation to dry out the area.

Un pied de réservoir qui se dégrade par corrosion augmente le risque d'ouverture du bac et quel que soit le produit stocké, peut causer des dommages matériels et humains et, engendrer des pertes financières importantes.A tank foot that deteriorates through corrosion increases the risk of the tank opening and, regardless of the product stored, can cause material and human damage and cause significant financial losses.

Le premier problème est qu'une fuite en fond de bac, sur les soudures des tôles de fond et des tôles de fond elles-mêmes ou encore, aux droits des soudures d'angles de liaison de la virole inférieure et des tôles marginales, peut être occultée par l'application d'un revêtement extérieur.The first problem is that a leak at the bottom of the tank, on the welds of the bottom plates and the bottom plates themselves or even, in line with the fillet welds connecting the lower shell and the marginal plates, can concealed by the application of an exterior coating.

Il n'y a pas non plus de système d'investigation fiable à 100%, telle l'émission acoustique, pour s'affranchir de l'état de l'intégrité du fond de bac. En effet, les résultats sont souvent faussés par la présence de paraffine dans le fond de bac, dans le cas d'un stockage d'hydrocarbure.Nor is there a 100% reliable investigation system, such as acoustic emission, to overcome the state of integrity of the bottom of the tank. Indeed, the results are often falsified by the presence of paraffin in the bottom of the tank, in the case of hydrocarbon storage.

Toutes les propositions et tests réalisés actuellement ne répondent pas aux conditions minimales recommandées pour permettre la réalisation des visites inspections, tout en préservant l'intégrité de l'équipement protégé.All the proposals and tests currently carried out do not meet the minimum conditions recommended to allow inspection visits to be carried out, while preserving the integrity of the protected equipment.

Le deuxième problème est que pour les bacs équipés de déflecteurs soudés, les interventions ne permettent que des actions de maintenance et d'entretien mais pas de remplacement de matériel pendant la période d'utilisation en production.The second problem is that for tanks equipped with welded deflectors, the interventions only allow maintenance and upkeep actions but no replacement of equipment during the period of use in production.

Le seul moyen d'intervention pour des gros travaux de remplacement ou réparation travaux à chaud est lors d'une période d'arrêt de production ou de visite décennale réglementaire.The only means of intervention for major work of replacement or repair of hot work is during a period of production stoppage or a regulatory ten-year visit.

Pour les bacs non équipés de déflecteurs, le problème qui se présente est la pose de ces protections, bac en service. Impossible d'installer un déflecteur par soudage. L'issue de cette situation est l'application d'un revêtement mais qui reste inadapté car il masque de possibles fuites provenant du dessous du fond de bac.

  • De plus malgré les réponses apportées aux problèmes ci-dessus par l'invention initiale protégée par le brevet précédent du même inventeur et dont la présente nouvelle demande de brevet est un perfectionnement, il persiste d'autres problèmes rencontrés sur cette invention initiale et qui sont : l'absence de véritable fixation du déflecteur car les bras de maintien ne sont fixés à la paroi que par des aimants et les bras d'appui ne font que s'y appuyer par simple contact
  • la faiblesse de l'effort du plaquage de joint sur la robe/paroi du réservoir, car le joint est plaqué sur cette paroi par le simple fait de la mise en place de la tôle de protection et du maintien de celle-ci par les aimants ;
  • la force d'aimantation est difficilement prévisible d'une part suivant l'état de la tôle du réservoir et d'autre part suivant les charges appliquées sur la tôle de protection et qui dépendent :
    • des pays dans lesquels est installé le matériel, suivant les conditions météorologiques locales comme la pluie diluvienne, la neige, le gel, le sable, le vent ... ;
    • de la densité des produits utilisés tels que pour les tests incendie ;
    • des risques de décrochage des aimants par choc lors des interventions de maintenance ou de visites programmées ;
  • l'inclinaison initiale du déflecteur multiplie le nombre d'obstacles rencontrés lors du montage. Il en découle, une multiplication du travail à effectuer et des risques d'infiltration, découpe, pose et raccordements de joints d'étanchéité.
For tanks not equipped with deflectors, the problem that arises is the installation of these protections, tank in service. Impossible to install a deflector by welding. The outcome of this situation is the application of a coating but which remains unsuitable because it masks possible leaks from below the bottom of the tank.
  • Moreover, despite the answers provided to the above problems by the initial invention protected by the previous patent of the same inventor and of which the present new patent application is an improvement, there persist other problems encountered on this initial invention and which are : the absence of real fixing of the deflector because the holding arms are only fixed to the wall by magnets and the support arms only press against it by simple contact
  • the low effort of pressing the seal against the shell/wall of the tank, because the seal is pressed against this wall by the simple fact of the installation of the protective sheet and its maintenance by the magnets ;
  • the magnetization force is difficult to predict on the one hand depending on the state of the tank sheet and on the other hand depending on the loads applied to the protective sheet and which depend on:
    • countries in which the equipment is installed, depending on local weather conditions such as torrential rain, snow, frost, sand, wind, etc.;
    • the density of the products used, such as for fire tests;
    • risks of the magnets detaching by shock during maintenance operations or scheduled visits;
  • the initial inclination of the deflector multiplies the number of obstacles encountered during assembly. This results in a multiplication of the work to be done and the risks of infiltration, cutting, installation and connections of seals.

Au vu des difficultés rencontrées, citées au précédent brevet, pour installer ou réparer par soudage les protections de tôles marginales, pendant l'utilisation des bacs et, du manque d'efficacité ou de l'occultation occasionnés par la présence de revêtements de pieds de structures (et qui ont été résolus par celui-ci) et, de ceux cités ci-dessus à la nouvelle demande de brevet de perfectionnement.In view of the difficulties encountered, cited in the previous patent, to install or repair by welding the protections of the marginal plates, during the use of the trays and, of the lack of efficiency or the concealment caused by the presence of coatings of the feet of structures (and which have been solved by it) and, from those cited above to the new patent application for improvement.

Une solution aux problèmes posés est la pose d'un déflecteur, pour protéger les pieds de paroi métallique de structure reposant sur une dalle support (telle qu'en béton) ou semelle d'appui, des infiltrations liquides, comportant :

  • au moins une tôle de protection, inclinée vers le bas en s'éloignant de la dite paroi quand le déflecteur est en position opérationnelle ;
  • au moins un joint d'étanchéité souple fixé le long du bord supérieur, quand le déflecteur est en position opérationnelle, de cette tôle inclinée et apte à venir en contact étanche contre la dite paroi de structure dont il épouse la forme ;
  • au moins un bras de maintien de la tôle à laquelle une de ses extrémités est fixée vers le dit bord supérieur de la dite tôle et l'autre extrémité dite distale, est apte à se solidariser à un élément de ladite structure, tel que la paroi de celle-ci d'une manière réversible et à en être désolidarisée, rendant le déflecteur démontable et, tel que suivant la présente invention:
  • le dit bras de maintien est un bras de plaquage de la tôle, apte à faire appuyer le joint d'étanchéité du bord supérieur de celle-ci contre la paroi de la structure quand le déflecteur est en position opérationnelle, et ce dernier comporte en outre :
  • au moins un support disposé vers le bord inférieur de la tôle quand celle-ci est installée autour de la structure à protéger (c'est-à-dire quand le déflecteur est en position opérationnelle), et séparable en au moins deux parties aptes à rendre le déflecteur démontable, dont l'une supérieure est fixée par-dessous la tôle et l'autre inférieure à la dalle support de la paroi de structure ou encore, à la semelle de renfort de tout accessoire de cette structure tel qu'une porte de nettoyage.
A solution to the problems posed is the installation of a deflector, to protect the feet of the metal wall of a structure resting on a support slab (such as concrete) or bearing sole, from liquid infiltration, comprising:
  • at least one protective sheet, inclined downwards away from said wall when the deflector is in the operational position;
  • at least one flexible seal fixed along the upper edge, when the deflector is in the operational position, of this inclined sheet and capable of coming into leaktight contact against the said structural wall whose shape it matches;
  • at least one arm for holding the sheet to which one of its ends is fixed towards said upper edge of said sheet and the other so-called distal end, is able to be secured to an element of said structure, such as the wall thereof in a reversible manner and to be detached from it, making the deflector removable and, as according to the present invention:
  • the said retaining arm is an arm for pressing the sheet metal, capable of pressing the sealing gasket of the upper edge of the latter against the wall of the structure when the deflector is in the operational position, and the latter further comprises :
  • at least one support arranged towards the lower edge of the sheet when the latter is installed around the structure to be protected (that is to say when the deflector is in the operational position), and separable into at least two parts capable of make the deflector removable, one upper one of which is fixed underneath the sheet metal and the other lower to the support slab of the wall of the structure or even to the reinforcement plate of any accessory of this structure such as a door of cleaning.

Suivant des modes préférentiels de réalisation de l'invention, deux solutions sont alors possibles pour la réalisation de ce bras de plaquage suivant d'une part l'état de l'anneau ou de la galette en béton, sur lequel s'appuie la structure dont on veut protéger le pied de paroi, ainsi que de la qualité de l'état de surface et de la nature du matériau de cette paroi de la structure, et d'autre part soit suivant la possibilité de pré fabriquer les tôles du déflecteur pour qu'elles soient adaptées à la structure concernée (par exemple par prise de gabarit) soit d'avoir à s'adapter sur place à cette structure lors de la pose du déflecteur :

  • la première solution, surtout intéressante quand l'anneau de béton est dégradé en pied de paroi de la structure et/ou que la paroi du réservoir permet de s'y fixer d'une manière réversible et non invasive pour la paroi et/ou quand on doit s'adapter sur place à celle-ci, est que le bras le bras de maintien (5), qui est donc suivant l'invention un bras de plaquage, de la tôle (1) est situé au-dessus de celle-ci, appuie sur elle par le dessus quand le déflecteur est en position opérationnelle et comporte à son extrémité distale au moins un moyen de fixation réversible et non invasive pour la paroi, comme un aimant ou une ventouse, apte à se solidariser, magnétiquement ou par effet d'aspiration ou autre, à la paroi ;
  • la deuxième solution, surtout intéressante quand l'anneau en béton est en bon état et que l'on peut préfabriquer la tôle du déflecteur pour qu'elle soit adaptée à la structure (ce qui est le cas par exemple des structures neuves) est que le bras de maintien, qui est donc suivant l'invention un bras de plaquage situé au-dessous de cette tôle de protection et séparable en au moins deux parties (l'une supérieure est fixée par-dessous la tôle et l'autre inférieure à la dalle support de la paroi de structure ou encore, à la semelle de renfort de tout accessoire de cette structure), les extrémités deux dites parties se faisant face étant aptes à se « clipser » entre elles par appui de l'une contre l'autre et déplacement de l'une dans l'autre (voir un exemple ci-aprés de cette définition du clipsage et comme représenté sur la figure 10) lors de la mise en place du déflecteur et à se maintenir solidaires entre elles malgré leur mise en traction par la réaction du joint qui se trouve comprimé lors de leur clipsage, mais ces extrémités deux dites parties se faisant face étant aptes à être déclipsées et donc désolidarisées par une mise en traction supérieure.
According to preferred embodiments of the invention, two solutions are then possible for the production of this pressing arm following on the one hand the state of the ring or of the concrete slab, on which the structure rests. which one wants to protect the foot of the wall, as well as the quality of the surface state and the nature of the material of this wall of the structure, and on the other hand either according to the possibility of pre-manufacturing the deflector sheets for that they are adapted to the structure concerned (for example by taking a template) or that they have to be adapted on site to this structure when installing the deflector:
  • the first solution, especially interesting when the concrete ring is degraded at the foot of the wall of the structure and/or when the wall of the tank allows fixing to it in a reversible and non-invasive way for the wall and/or when must be adapted on site to it, is that the arm the holding arm (5), which is therefore according to the invention a plating arm, of the sheet (1) is located above that- ci, presses on it from above when the deflector is in the operational position and comprises at its distal end at least one reversible and non-invasive fixing means for the wall, such as a magnet or a suction cup, capable of being secured, magnetically or by suction or other effect at the wall;
  • the second solution, which is especially interesting when the concrete ring is in good condition and the deflector plate can be prefabricated so that it is adapted to the structure (which is the case for new structures, for example) is that the holding arm, which is therefore according to the invention a pressing arm located below this protective sheet and separable into at least two parts (one upper is fixed below the sheet and the other lower the support slab of the wall of the structure or even to the reinforcement sole of any accessory of this structure), the ends of the two said parts facing each other being able to "clip" together by pressing one against the another and moving from one to the other (see an example below of this definition of clipping and as represented on the figure 10 ) during the installation of the deflector and to maintain solidarity with each other despite their traction by the reaction of the joint which is compressed during their clipping, but these ends two said parts facing each other being able to be unclipped and therefore separated by a higher traction.

Par ailleurs quel que soit le mode de réalisation retenu du bras de plaquage, suivant les deux solutions ci-dessus, et suivant des modes particuliers de réalisation de l'invention :

  • la tôle de déflecteur, quand celle-ci est en position opérationnelle, a une inclinaison permettant un écoulement de liquide sans retenue et une résistance à la charge verticale du liquide ;
  • le déflecteur suivant l'invention comporte un rebord vertical, le long du bord inférieur de la dite tôle inclinée quand le déflecteur est en position opérationnelle ;
  • un ensemble déflecteur est constitué de plusieurs éléments déflecteurs, ayant les caractéristiques ci-dessus, tous indépendants les uns des autres mais aptes à être positionnés les uns à la suite des autres d'une manière continue autour et contre les pieds de la paroi de la structure pour en protéger toute la périphérie ;
  • l'ensemble déflecteur est constitué d'éléments déflecteurs comportant au moins, le long d'un de ses bords latéraux, des éléments de couverture et aptes à venir recouvrir l'espace vide jusqu'à l'élément adjacent.
  • tant les supports, disposés vers le bord inférieur de la tôle, que les bras de plaquage, disposés vers son bord supérieur, peuvent être réglables pour être aptes à régler et ajuster la hauteur de la tôle inclinée de protection par rapport à la dalle ou l'anneau en béton, et maintenir d'une part cette tôle en appui sur la paroi de la structure à protéger et d'autre part en position inclinée suivant l'angle voulu.
Moreover, regardless of the chosen embodiment of the pressing arm, according to the two solutions above, and according to particular embodiments of the invention:
  • the baffle sheet, when in the operational position, has an inclination allowing unrestricted liquid flow and resistance to the vertical load of the liquid;
  • the deflector according to the invention comprises a vertical rim, along the lower edge of said inclined sheet when the deflector is in the operational position;
  • a deflector assembly consists of several deflector elements, having the above characteristics, all independent of each other but capable of being positioned one after the other in a continuous manner around and against the feet of the wall of the structure to protect the entire periphery;
  • the deflector assembly is made up of deflector elements comprising at least, along one of its lateral edges, covering elements and capable of coming to cover the empty space up to the adjacent element.
  • both the supports, arranged towards the lower edge of the sheet, and the pressing arms, arranged towards its upper edge, can be adjustable so as to be able to regulate and adjust the height of the inclined protective sheet relative to the slab or the 'concrete ring, and maintain on the one hand this sheet resting on the wall of the structure to be protected and on the other hand in an inclined position at the desired angle.

L'invention est donc comme dans la précédente demande de brevet, la pose d'un déflecteur démontable, qui désigne dans la présente description soit un élément déflecteur soit un ensemble déflecteur composé de plusieurs éléments déflecteurs, et tel que précisé ci-après.The invention is therefore, as in the previous patent application, the installation of a removable deflector, which designates in the present description either a deflector element or a deflector assembly composed of several deflector elements, and as specified below.

L'innovation étant le fait que la protection soit démontable et, qu'il ne soit donc pas nécessaire d'arrêter la production d'un bac pour la pose de la protection et également, les perfectionnements apportés tels que décrits ci-après et qui permettent :

  • dans le cas de bras de plaquage situés au-dessus de la tôle de protection et que l'on peut désolidariser, magnétiquement ou autre, de la paroi grâce à des aimants ou autres moyens de fixation réversible et non invasif pour la paroi:
    • la position des aimants, ou autres moyens, articulés qui se trouvent en ce cas au-dessus de la tôle de protection, ce qui donne un accès plus aisé à la manipulation de ceux-ci ;
    • les aimants (ou autres moyens de fixation réversibles) n'ont plus la même fonction que dans le brevet précédent. Ils ne servent plus de supports pour le maintien en hauteur de la tôle de protection mais, permettent désormais de maintenir la tôle et son joint d'étanchéité plaqués à la structure à étancher ;
    • le bras de maintien comporte un ridoir apte à régler la pression à exercer pour le plaquage du joint d'étanchéité ;
    • le bras de maintien est articulé à ses deux extrémités par des axes insérés dans des embouts permettant une rotation de l'ensemble afin de permettre de désunir l'aimant (ou autres moyens de fixation réversibles) de la paroi de la structure ;
    • les ridoirs servent également de poignées pour les montage/démontage des tôles de protection ;
  • dans le cas de bras de plaquage situés au-dessous de la tôle et désolidarisables par déclipssage de ces deux parties:
    • la simplification de fabrication qui en permet l'industrialisation (par exemple, la tôle de déflecteur peut être en ce cas réalisée par emboutissage en un seul tenant, et il n'y a pas d'élément rattaché à cette tôle hormis le joint d'étanchéité et la fixation des bras et supports),
    • la rapidité de la mise en oeuvre lors du montage / démontage des éléments tout en assurant l'étanchéité dans les zones constitués de multiples angles comme les côtés des portes de nettoyage,
    • dans cette solution tous les points particuliers, tels que piquages, portes de nettoyage, escaliers, etc.., peuvent être protégés soit suivant les descriptions enseignées ci-après soit de préférence pour une diminution des coûts, par des protections fixes, posées sur supports, recouvertes d'un produit d'étanchéité et qui n'empêchent pas de faire les contrôles manuels ou visuels par le côté de ces éléments fixes,
    • il ne reste alors, une fois les points particuliers protégés, qu'à placer les sections amovibles "standards" définies ci-dessus et telles que représentées sur la figure 10,
    • la standardisation des dimensions des tôles de déflecteur permet, en termes de dimensions et de poids, l'optimisation des chargements lors des transports,
    • le rendement réalisé par l'emboutissage des tôles standardisées donne une réactivité importante à une commande,
    • et donc comme plus c'est simple, plus c'est rapide aussi à monter, et plus cela diminue le coût d'ensemble de la protection, et plus c'est commercialisable,
    • Quel que soit la solution choisie pour la réalisation des bras de plaquage
      • la mise en place de supports réglables, fixés à l'anneau ou dalle béton ou encore à la semelle de renfort de la porte de nettoyage, tels que par une colle adaptée ou vissés, permet d'absorber les charges extérieures, sans désolidariser de plus, comme dans le cas de bras de plaquage fixés à la paroi de la structure au-dessus de la tôle de protection, des aimants (ou autres moyens de fixation réversibles) de la structure à protéger ;
      • les supports des déflecteurs, pouvant même être réglables suivant trois axes, sont aptes à ajuster l'espace vertical ou horizontal entre les déflecteurs dans leurs positions opérationnelles, ces axes de réglages sont :
        • l'axe de la glissière latérale de la pièce (partie arrondie) dans un guide ;
        • l'axe du coulissement en hauteur de la pièce sur un coulisseau ;
        • l'axe du coulissement en translation du coulisseau sur la base.
      • la position des supports permet de bloquer le pied du déflecteur et ainsi, donne la possibilité d'augmenter la charge exercée sur le déflecteur et par conséquent, augmente le plaquage du joint sur la paroi et améliore donc l'étanchéité de la zone à protéger lors des intempéries ou des tests incendie.
The innovation being the fact that the protection is removable and, therefore, it is not necessary to stop the production of a tray for the installation of the protection and also, the improvements made as described below and which allow:
  • in the case of pressing arms located above the protective sheet and which can be separated, magnetically or otherwise, from the wall using magnets or other means of reversible and non-invasive fixing for the wall:
    • the position of the magnets, or other means, articulated which are in this case above the protective sheet, which gives easier access to the manipulation thereof;
    • the magnets (or other reversible fastening means) no longer have the same function as in the previous patent. They no longer serve as supports for maintaining the height of the protective sheet but now make it possible to keep the sheet and its gasket plated against the structure to be sealed;
    • the holding arm comprises a turnbuckle capable of adjusting the pressure to be exerted for pressing the seal;
    • the holding arm is articulated at its two ends by axes inserted in end pieces allowing rotation of the assembly in order to allow the magnet (or other reversible fixing means) to be separated from the wall of the structure;
    • the turnbuckles also serve as handles for mounting/removing the protective plates;
  • in the case of pressing arms located below the sheet and which can be separated by unclipping these two parts:
    • the simplification of manufacture which allows industrialization (for example, the deflector sheet can in this case be produced by stamping in one piece, and there is no element attached to this sheet except the seal of sealing and fixing of arms and supports),
    • the speed of the implementation during the assembly / disassembly of the elements while ensuring the sealing in the zones made up of multiple angles such as the sides of the cleaning doors,
    • in this solution all the particular points, such as tappings, cleaning doors, stairs, etc., can be protected either according to the descriptions taught below or preferably for a reduction in costs, by fixed protections, placed on supports , covered with a sealing product and which do not prevent manual or visual checks from the side of these fixed elements,
    • all that remains is, once the particular points have been protected, to place the "standard" removable sections defined above and as represented on the figure 10 ,
    • the standardization of the dimensions of the deflector plates allows, in terms of dimensions and weight, the optimization of the loads during transport,
    • the yield achieved by the stamping of standardized sheets provides significant responsiveness to an order,
    • and therefore as the simpler it is, the faster it is also to mount, and the more it reduces the overall cost of protection, and the more it is marketable,
    • Whatever the solution chosen for the production of the pressing arms
      • the installation of adjustable supports, fixed to the ring or concrete slab or even to the reinforcement plate of the cleaning door, such as by a suitable glue or screwed, makes it possible to absorb the external loads, without further separating , as in the case of pressing arms fixed to the wall of the structure above the protective sheet, magnets (or other reversible fixing means) of the structure to be protected;
      • the deflector supports, which can even be adjustable along three axes, are able to adjust the vertical or horizontal space between the deflectors in their operational positions, these adjustment axes are:
        • the axis of the side slide of the part (rounded part) in a guide;
        • the axis of sliding in height of the part on a slider;
        • the axis of sliding in translation of the slider on the base.
      • the position of the supports makes it possible to block the foot of the deflector and thus gives the possibility of increasing the load exerted on the deflector and consequently increases the plating of the gasket on the wall and therefore improves the sealing of the area to be protected during weather or fire tests.

Chaque élément déflecteur (fig. 3 ref.1a 1b) qui constitue l'ensemble déflecteur comporte au moins, le long d'un de ses bords latéraux, des éléments de couverture (fig.4ref. 7) et (fig.4 ref.8) aptes à venir recouvrir l'espace vide jusqu'à l'élément adjacent.Each deflector element ( fig. 3 ref.1a 1b) which constitutes the deflector assembly comprises at least, along one of its lateral edges, cover elements ( fig.4 ref. 7) and ( fig.4 ref.8) capable of covering the empty space up to the adjacent element.

Le déflecteur (fig.1 et 10 ref.1) est constitué principalement, d'une tôle de protection formée sur deux faces.The deflector ( fig.1 and 10 ref.1) mainly consists of a protective sheet formed on two sides.

Les faces sont à deux positions angulaires. Une face inclinée à 15° minimum (fig.1 et 10 ref. 1), et d'une révolution adaptée au rayon du réservoir et, d'un profilé anti-goutte avec rebord vertical en partie basse (fig.1 et 10 ref. 3), limitant d'écoulement vers le sol ou caniveau (fig.2 ref.26).The faces are at two angular positions. A face inclined at 15° minimum ( fig.1 and 10 ref. 1), and a revolution adapted to the radius of the tank and, an anti-drip profile with vertical edge in the lower part ( fig.1 and 10 ref. 3), restricting flow towards the ground or gutter ( fig.2 ref.26).

L'inclinaison de 15° minimum du déflecteur (fig.1 et 10 ref.1) permet d'éviter et de passer sous la majeure partie des éléments fixés au réservoir de stockage, escalier, piquages, etc...The minimum 15° inclination of the deflector ( fig.1 and 10 ref.1) makes it possible to avoid and pass under most of the elements fixed to the storage tank, stairs, taps, etc...

Néanmoins, la forme et la pente des déflecteurs peuvent être modifiées suivant les obstacles rencontrés tels que, la porte de nettoyage (fig.3 ref.27) ou encore à la présence de tôles de renforts (fig.3 ref.10 11) soudées à la paroi (14) du réservoir et, de tout autres éléments existants sur site.Nevertheless, the shape and slope of the deflectors can be modified according to the obstacles encountered such as the cleaning door ( fig.3 ref.27) or the presence of reinforcement plates ( fig.3 ref.10 11) welded to the wall (14) of the tank and any other existing elements on site.

Comme indiqué ci-dessus, des obstacles peuvent gêner la mise en place des déflecteurs, les tôles de déflecteurs (1) sont alors découpées et la pose de joint en nitrile peut assurer, l'étanchéité de ces zones particulières.As indicated above, obstacles can hinder the installation of the deflectors, the deflector plates (1) are then cut out and the installation of a nitrile seal can ensure the tightness of these particular areas.

Suivant la première solution du mode de réalisation du bras de plaquage suivant l'invention et comme représenté sur les figures 1 et 2, ce bras de placage est situé au-dessus de la tôle de protection du déflecteur, et cette tôle inclinée (1) est équipée de ce bras de maintien/placage (fig.2 ref.5) (visible en arrière-plan) servant en premier lieu au maintien du déflecteur (1) dans sa position opérationnelle et, en second lieu au réglage de la pression nécessaire à la bonne application du joint (fig.1 ref.2) sur la paroi (14) du réservoir.According to the first solution of the embodiment of the pressing arm according to the invention and as shown in the figure 1 and 2 , this cladding arm is located above the protective sheet of the deflector, and this inclined sheet (1) is equipped with this holding/cladding arm ( fig.2 ref.5) (visible in the background) serving primarily to hold the deflector (1) in its operational position and, secondly, to adjust the pressure necessary for the correct application of the seal ( fig.1 ref.2) on the wall (14) of the tank.

Le bras de maintien est articulé à ses deux extrémités par des axes (fig.1 ref.31a 31b) insérés dans des embouts (fig.1 ref.37 38) permettant une rotation de l'ensemble afin de désunir l'aimant (ou autre moyen de fixation réversible) (fig.1 ref.12) à la paroi magnétique (14).The holding arm is articulated at its two ends by axes ( fig.1 ref.31a 31b) inserted in end caps ( fig.1 ref.37 38) allowing rotation of the assembly in order to disunite the magnet (or other reversible fixing means) ( fig.1 ref.12) to the magnetic wall (14).

Les embouts du bras de maintien sont sur sa partie inférieure et côté déflecteur, boulonné (fig.1 ref.35a 41a) et sur sa partie supérieure, équipé de l'aimant (ou autres moyens de fixation réversible) (fig.1 ref.12)The ends of the holding arm are on its lower part and on the deflector side, bolted ( fig.1 ref.35a 41a) and on its upper part, equipped with the magnet (or other means of reversible fixing) ( fig.1 ref.12)

L'ensemble des éléments constituant le bras de maintien est rattaché au ridoir (fig.1 ref.29) par des chapes (fig.1 ref.39a 39b), qui permet d'effectuer un réglage par rotation du ridoir afin d'obtenir une bonne application du joint (fig.1 ref.2).All of the elements making up the retaining arm are attached to the turnbuckle ( fig.1 ref.29) by clevises ( fig.1 ref.39a 39b), which allows adjustment by rotation of the turnbuckle in order to obtain a good application of the joint ( fig.1 ref.2).

Le ridoir (fig.1 ref.29) est l'élément qui permet d'affiner l'application du joint (fig.1 ref.2) sur la paroi (14), par vissage/dévissage.The turnbuckle ( fig.1 ref.29) is the element which makes it possible to refine the application of the joint ( fig.1 ref.2) on the wall (14), by screwing/unscrewing.

La dernière utilisation de ces bras de maintien (5) est pour la manipulation des déflecteurs lors de leur installation, ces bras peuvent avoir la fonction de poignées de transport.The last use of these holding arms (5) is for handling the deflectors during their installation, these arms can have the function of carrying handles.

Les bras de maintien (5) sont situés au-dessus du déflecteur (1), quand le déflecteur est en position opérationnelle, et sont aptes à venir en contact contre la paroi (14) au-dessus du joint d'étanchéité (fig.1 ref.2) par une rotation sur son axe (fig.1 ref.31b).The holding arms (5) are located above the deflector (1), when the deflector is in the operational position, and are capable of coming into contact against the wall (14) above the seal ( fig.1 ref.2) by a rotation on its axis ( fig.1 ref.31b).

Le déflecteur destiné à une paroi métallique (14) de structure est tel que, au moins le bras de maintien (fig.2 ref.5) comporte à son extrémité distale au moins un aimant (ou autre moyen de fixation réversible) (12) apte à se solidariser magnétiquement à la paroi (14).The deflector intended for a metallic structural wall (14) is such that at least the holding arm ( fig.2 ref.5) comprises at its distal end at least one magnet (or other reversible fixing means) (12) able to be magnetically attached to the wall (14).

Suivant la deuxième solution du mode de réalisation du bras de plaquage suivant l'invention, comme représenté sur la figure 10, le bras de plaquage (5) est situé au-dessous de la tôle de protection : il est séparable en au moins deux parties, l'une supérieure (45) étant fixée (46) par-dessous la tôle (1), tel que par vissage, et l'autre inférieure dont l'extrémité distale est fixée à la dalle support de la paroi de structure ou à un support de base (34e) (tel que par soudure comme représenté sur la figure 10), ou encore, à la semelle de renfort de tout accessoire de cette structure.According to the second solution of the embodiment of the pressing arm according to the invention, as shown in the figure 10 , the pressing arm (5) is located below the protective sheet: it is separable into at least two parts, the upper one (45) being fixed (46) below the sheet (1), such only by screwing, and the other lower one, the distal end of which is fixed to the support slab of the structural wall or to a base support (34e) (such as by welding as shown in the figure 10 ), or again, to the reinforcement sole of any accessory of this structure.

Et dans cette deuxième solution, les extrémités (45a,45b) des deux dites parties se faisant face sont aptes à se « clipser » entre elles (45a,45b) par appui de l'une contre l'autre et déplacement de l'une dans l'autre lors de la mise en place du déflecteur et à se maintenir solidaires entre elles malgré leur mise en traction par la réaction du joint qui se trouve comprimé lors de leur clipsage, mais ces extrémités (45a,45b) des deux dites parties se faisant face étant aptes à être déclipsées et donc désolidarisées par une mise en traction de force supérieure.And in this second solution, the ends (45a, 45b) of the two said parts facing each other are able to "clip" together (45a, 45b) by pressing one against the other and moving one in the other during the installation of the deflector and to remain integral with each other despite their traction by the reaction of the joint which is compressed during their clipping, but these ends (45a, 45b) of the two said parts facing each other being able to be unclipped and therefore separated by a higher force traction.

Un exemple de réalisation de ces parties clipsables est représentée d'une manière schématique sur la figure 10 où l'une (45a), située du côté de la partie supérieure (45) du bras de placage (5), a son extrémité en forme d'anneau partiellement ouvert et apte à s'ouvrir un peu plus élastiquement pour recevoir l'extrémité de l'autre (45b), située du coté de la partie inférieure du bras (5) et qui est en forme de cylindre se logeant alors dans le dit anneau et s'y trouvant bloqué par l'effet de refermeture de celui-ci en arrière du cylindre ; dans d'autres modes de réalisation, ces formes en cylindre et en anneau partiellement ouvert peuvent être inversées, l'extrémité de la partie supérieure (45a) pouvant être en forme de cylindre et celle de la partie inférieure (45b) en forme d'anneau partiellement ouvert.An embodiment of these clip-on parts is represented schematically on the figure 10 where one (45a), located on the side of the upper part (45) of the pressing arm (5), has its end in the form of a partially open ring and capable of opening a little more elastically to receive the end of the other (45b), located on the side of the lower part of the arm (5) and which is in the form of a cylinder then being housed in the said ring and being blocked there by the closing effect of the latter ci behind the cylinder; in other embodiments, these cylindrical and partially open ring shapes can be reversed, the end of the upper part (45a) being able to be shaped like a cylinder and that of the lower part (45b) being shaped like a partially open ring.

Afin de rendre les déflecteurs transportables, l'ensemble du déflecteur est découpé en sections de longueur adaptée à un transport humain aisé évitant ainsi l'intervention d'engins dans la cuvette du réservoir.In order to make the deflectors transportable, the entire deflector is cut into sections of length suitable for easy human transport, thus avoiding the intervention of machinery in the tank bowl.

La matière du déflecteur est en acier inoxydable, aluminium ou encore en tôles galvanisées ou autre, suivant les demandes du client.The material of the deflector is in stainless steel, aluminum or even in galvanized or other sheets, according to the customer's requests.

Les tôles du déflecteur suivant l'invention comportent un rebord vertical (3), le long du bord inférieur des dites tôles inclinées quand le déflecteur est en position opérationnelle : ce rebord peut être soit un joint dit profilé anti-goutte (3, 3a, 3b suivant les fig. 1,4 et 5), ou un simple pliage de la tôle (1) elle-même (suivant la fig.10).The plates of the deflector according to the invention comprise a vertical rim (3), along the lower edge of the said inclined plates when the deflector is in the operational position: this rim can be either a joint called an anti-drip profile (3, 3a, 3b according to fig. 1 , 4 and 5 ), or a simple bending of the sheet (1) itself (depending on the fig.10 ).

Les éléments posés sur un bac ou dans une cuvette de bac ne doivent pas être un des trois éléments du triangle du feu.The elements placed on a tank or in a tank basin must not be one of the three elements of the fire triangle.

L'étanchéité entre le déflecteur et la paroi du réservoir (fig.1 et 10 ref.14) s'effectue à l'aide d'un joint en nitrile (fig.1 et 10 ref.2) ou autre matière adaptée à l'environnement, inséré dans un profilé cintré (fig.1 ref.4) qui lui-même est emboité dans la tôle (1) du déflecteur.The seal between the deflector and the tank wall ( fig.1 and 10 ref.14) is carried out using a nitrile seal ( fig.1 and 10 ref.2) or other material adapted to the environment, inserted in a curved profile ( fig.1 ref.4) which itself is fitted into the sheet (1) of the deflector.

L'étanchéité entre le déflecteur et la paroi de la porte de nettoyage (fig.3 ref.27), en exemple et quand on veut utiliser aussi un élément de déflecteur démontable, garde le même principe de mise en place que celui cité ci-dessus mais, en utilisant des profils de joints et de rails (profilés) de formes et de dimensions différentes (fig.5b ref.1a 1c).The seal between the deflector and the wall of the cleaning door ( fig.3 ref.27), as an example and when you also want to use a removable deflector element, keeps the same principle of installation as that mentioned above but, by using profiles of joints and rails (profiles) of shapes and of different sizes (fig.5b ref.1a 1c).

Chaque élément de l'ensemble déflecteur qui le constitue comporte une tôle (fig.3 ref.7) (fig.4 7) (fig.5 ref.7 détail B) et un joint de recouvrement (fig.4 ref.8) (fig.5 ref.8 détail B) le long d'un de ses bords latéraux et apte à venir recouvrir un élément adjacent.Each element of the deflector assembly which constitutes it comprises a plate ( fig.3 ref.7) ( fig.4 7 ) ( fig.5 ref.7 detail B) and a cover joint ( fig.4 ref.8) ( fig.5 ref.8 detail B) along one of its side edges and capable of covering an adjacent element.

Une tôle de recouvrement (fig.4 ref.7) est soudée sur la tôle de protection (fig.4 ref.1a) permettant ainsi de combler et protéger la zone vide entre les tôles de protections (fig.4 ref.1a et 1b).A cover plate ( fig.4 ref.7) is welded to the protection plate ( fig.4 ref.1a) thus making it possible to fill and protect the empty zone between the protective sheets ( fig.4 ref.1a and 1b).

Un joint (8) de recouvrement, selon (fig. 4 et 5), assurent l'étanchéité entre deux éléments déflecteurs en position opérationnelle.A joint (8) covering, according to ( fig. 4 and 5 ), seal between two deflector elements in the operational position.

Les supports réglables (fig.2 ref.6) (fig.9a ref.6) sont d'une part, fixés (fig. 7 ref.32) aux déflecteurs tels que par soudage ou vissage/boulonnage et d'autre part, fixés à l'anneau béton (fig. 2 ref.23) soit par collage, soit par vissage ou fixés sur la semelle de renfort en acier (fig.9a ref.9) de la porte de nettoyage par collage, suivant l'emplacement où est installé le support et suivant les recommandations du client.The adjustable brackets ( fig.2 ref.6) ( fig.9a ref.6) are, on the one hand, fixed ( fig. 7 ref.32) to the deflectors such as by welding or screwing/bolting and on the other hand, fixed to the concrete ring ( fig. 2 ref.23) either by gluing, or by screwing or fixed on the steel reinforcement plate ( fig.9a ref.9) of the cleaning door by gluing, depending on the location where the support is installed and according to the customer's recommendations.

Quatre pièces constituent le support réglable modèle 34a en exemple (fig.6, 7, 8) :

  • La base du support, un profilé en Té (fig.8 ref.34a) fixé sur l'anneau béton (23) ou la semelle de renfort de la porte de nettoyage (fig.9a ref.9), soit par une colle adaptée soit par une fixation vissée.
  • Un coulisseau (fig.8 ref.13) permettant un déplacement en translation du support. Deux vis (fig.8 ref.35d, e) traversant la base du support par les rainures, maintiennent la pièce en position d'utilisation.
  • Un guide coulissant (fig.8 ref.33), munis de trous oblongs, permet de régler la hauteur du déflecteur afin d'ajuster les éléments de protection les uns aux autres.
  • Une tôle pliée (fig.8 ref.32) soudée sous la tôle (1) du déflecteur, l'extrémité inférieure arrondie de cet élément est pincée dans le guide cité ci-dessus et permet de maintenir en position le déflecteur après réglage et serrage de la boulonnerie (fig.8 ref.35b,c,d,e,f,g,h) et (fig.8 ref.41b,c,d,e,f).
Four pieces make up the Model 34a Adjustable Stand as an example ( fig.6, 7 , 8 ):
  • The base of the support, a T-profile ( fig.8 ref.34a) fixed to the concrete ring (23) or the reinforcement plate of the cleaning door ( fig.9a ref.9), either by a suitable glue or by a screwed fixing.
  • A slider ( fig.8 ref.13) allowing a translational movement of the support. Two screws ( fig.8 ref.35d, e) crossing the base of the support by the grooves, maintain the part in the position of use.
  • A sliding guide ( fig.8 ref.33), fitted with oblong holes, allows the height of the deflector to be adjusted in order to adjust the protective elements to each other.
  • A bent sheet ( fig.8 ref.32) welded under the sheet metal (1) of the deflector, the rounded lower end of this element is pinched in the guide mentioned above and makes it possible to maintain position the deflector after adjusting and tightening the bolts ( fig.8 ref.35b,c,d,e,f,g,h) and ( fig.8 ref.41b,c,d,e,f).

Plusieurs types de supports peuvent être utilisés pour fixés les tôles de déflecteurs.Several types of brackets can be used to fix the deflector sheets.

En exemple sur le schéma (fig. 6) :

  • Support de base (34a) - ensemble fixé par le dessus de l'anneau béton (23) ou semelle de renfort (9).
  • Support de base (34b) - ensemble fixé par la ceinture de l'anneau béton (23).
  • Support de base (34c) - ensemble collé par le dessus et la ceinture de l'anneau béton (23).
  • Support de base (34d) - ensemble fixé par des vis (fig.6 35k, m) sur la tôle marginale (15) et maintenu par une autre vis (fig.6 35j) sur la ceinture de l'anneau béton (23).
As an example in the diagram ( fig. 6 ):
  • Base support (34a) - assembly fixed by the top of the concrete ring (23) or reinforcement sole (9).
  • Base support (34b) - assembly fixed by the belt of the concrete ring (23).
  • Base support (34c) - assembly glued by the top and the belt of the concrete ring (23).
  • Base support (34d) - set fixed by screws ( fig.6 35k, m) on the marginal plate (15) and held by another screw ( fig.6 35j) on the belt of the concrete ring (23).

Les supports des éléments déflecteurs désignés ci-dessus (6), doivent permettre d'effectuer un réglage sur trois axes, afin d'ajuster l'espace vertical ou horizontal entre les éléments déflecteurs dans leurs positions opérationnelles.The supports of the deflector elements designated above (6), must allow adjustment on three axes, in order to adjust the vertical or horizontal space between the deflector elements in their operational positions.

Suivant le mode de réalisation de la figure 10, un seul support de base (34e) peut être fixé sur l'anneau béton (23) (tel que par vissage sur le côté de cet anneau (23) comme représenté sur cette figure 10) et supporter à la fois les extrémités distales des parties inférieures du support (6) de tôle (1) de protection et du bras de maintien/placage (5) de cette tôle (1), les parties supérieures (45,45') de ce support (6) de tôle (1) et du bras (5) étant fixées (46,46') par vissage/boulonnage/rivetage (ou autre moyen) sur le dessous de la tôle (1) inclinée de protection ; les supports (6) de tôle (1) peuvent être réglables comme dans les modes de réalisation décrits et représentés dans les fig. 1, 7 et 8, ou clipsables (45a',45b') comme représenté sur la fig.10 et suivant les mêmes caractéristiques que décrites pour le clipsage des extrémités (45a,45b) des deux parties séparables du bras de placage (5) décrites précédemment.According to the embodiment of the figure 10 , a single base support (34e) can be fixed to the concrete ring (23) (such as by screwing onto the side of this ring (23) as shown in this figure 10 ) and support both the distal ends of the lower parts of the support (6) of the protective sheet (1) and of the holding/placing arm (5) of this sheet (1), the upper parts (45,45') of this support (6) of sheet (1) and of the arm (5) being fixed (46,46') by screwing/bolting/riveting (or other means) on the underside of the sheet (1) inclined for protection; the sheet (1) supports (6) can be adjustable as in the embodiments described and shown in the fig. 1 , 7 and 8 , or clip-on (45a', 45b') as shown in the fig.10 and according to the same characteristics as described for the clipping of the ends (45a, 45b) of the two separable parts of the plating arm (5) described above.

Pour standardiser la fabrication de ces pièces clipsables et donc la simplifier, les parties supérieures (45,45') respectivement des supports (6) et des bras (5) peuvent être identiques et fixées sous des pièces intermédiaires solidaires du dessous de la tôle (1) de protection, ces pièces (non représentées dans l'exemple de la figure 10) étant de hauteurs différentes pour compenser la différence de hauteurs entre les bras (5), plus hauts, et les supports (6), plus bas, afin que les parties inférieures de ces bras et de ces supports soient elles aussi identiques.To standardize the manufacture of these clip-on parts and therefore simplify it, the upper parts (45,45') respectively of the supports (6) and the arms (5) can be identical and fixed under intermediate parts integral with the underside of the sheet ( 1) protection, these parts (not shown in the example of the figure 10 ) being of different heights to compensate for the difference in height between the arms (5), higher, and the supports (6), lower, so that the lower parts of these arms and these supports are also identical.

Les variantes de fabrication et de montages sont multiples.There are many manufacturing and assembly variants.

Les déflecteurs peuvent être utilisés sur toutes structures nécessitant une protection et un maintien d'intégrité.The deflectors can be used on all structures requiring protection and maintenance of integrity.

Les matériaux utilisés pour la réalisation des éléments de déflecteur (1) peuvent être du zinc, du plexiglas ou un plastique si le risque au feu n'est pas avéré et suivant les conditions d'utilisation.The materials used for making the deflector elements (1) can be zinc, Plexiglas or plastic if the fire risk is not proven and depending on the conditions of use.

La variante peut être faite sur les épaisseurs des matériaux utilisés, leurs poids et leurs coûts.The variant can be made on the thicknesses of the materials used, their weights and their costs.

Les joints d'étanchéité peuvent être réalisés avec tout produit souple et extrudable afin d'épouser la zone à étancher et faciliter l'insertion de celui-ci dans un profilé support.The seals can be made with any flexible and extrudable product in order to match the area to be sealed and facilitate its insertion into a support section.

Les aimants peuvent être de formes variables, en fer à cheval, cylindriques ou parallélépipédiques, voire d'une forme prédéfinie à la commande et peuvent servir autant pour les bras de maintien que pour les supports.The magnets can be of variable shapes, horseshoe, cylindrical or parallelepipedal, or even of a predefined shape when ordering and can be used both for the holding arms and for the supports.

Les fixations aux parois amagnétiques peuvent être réalisées avec des ventouses ou encore des platines collées, ou fixées par tout autre moyen de fixation réversible, aux parois de la structure suivant la nature du support sur lequel le déflecteur doit être installé.The fixings to the non-magnetic walls can be made with suction cups or glued plates, or fixed by any other reversible fixing means, to the walls of the structure depending on the nature of the support on which the deflector must be installed.

Le premier intérêt de cette protection est le fait que celle-ci soit démontable mais aussi, de par ce fait, puisse permettre le passage de matériel de contrôle sur la structure tels que :

  • Mesures d'épaisseurs des viroles par robots. Ces robots sont équipés de chenilles magnétiques qui permettent leurs déplacements du pied de bac jusqu'à la dernière virole supérieure ;
  • Mesures des pertes d'épaisseurs des tôles marginales effectuées par un robot se déplaçant horizontalement sur le pied de bac ;
  • Mesures d'épaisseurs standards par contrôle ultrasons, effectuées manuellement par des techniciens équipés de palpeurs ultrasons ;
  • Le contrôle ACFM Alternative Current Field Measurement consistant à contrôler la qualité des soudures externes (fig.1 18) de liaison, de la première virole basse de l'enveloppe du bac avec la tôle marginale.
The first advantage of this protection is the fact that it is removable but also, therefore, can allow the passage of control equipment on the structure such as:
  • Shell thickness measurements by robots. These robots are equipped with magnetic caterpillars which allow them to move from the foot of the tank to the last upper ring;
  • Measurements of the loss of thickness of the marginal plates carried out by a robot moving horizontally on the foot of the tank;
  • Standard thickness measurements by ultrasonic control, carried out manually by technicians equipped with ultrasonic probes;
  • The ACFM Alternative Current Field Measurement control consisting in controlling the quality of external welds ( fig.1 18) for connecting the first lower ferrule of the tank casing with the marginal plate.

Certains de ces contrôles sont effectués lors de visites triennales et d'autres décennales. Néanmoins, le besoin primordial reste la possibilité d'effectuer l'inspection visuelle du pied de bac (fig.1 ref.19) qui elle, peut se faire à tout moment, autant que nécessaire suivant les législations en vigueur.Some of these checks are carried out during inspections every three years and others ten years. Nevertheless, the essential need remains the possibility of carrying out the visual inspection of the foot of the tank ( fig.1 ref.19) which can be done at any time, as far as necessary according to the legislation in force.
