Description

La présente invention se rapporte à un procédé de construction d'une paroi formée d'une succession de formats juxtaposés de feuilles de tôle tendues sur une ossature ou une charpente, ainsi qu'à la paroi et au conteneur ou à l'enveloppe ainsi obtenus.The present invention relates to a method of constructing a wall formed of a succession of juxtaposed formats of sheet metal sheets stretched on a frame or a frame, as well as the wall and to the container or envelope as well obtained.

Les silos placés à l'intérieur des bâtiments sont fréquemment réalisés à partir d'une charpente ou d'une ossature procurant la forme générale du silo, charpente sur laquelle est monté un habillage en feuilles de tôle.Silos placed inside buildings are frequently made from a frame or a frame providing the general shape of the silo, frame on which is mounted a covering in sheet metal sheets.

L'habillage du silo constitue la paroi intérieure proprement dite de celui-ci, en contact direct avec la matière ou les produits stockés. En général, cet habillage est fixé sur l'ossature ou la charpente par des moyens conventionnels tels que vis, rivets ou autres, sachant que la face intérieure de l'habillage doit être la plus lisse possible. Dans ce mode de construction, il s'avère également nécessaire de prévoir aux endroits les plus exposés aux chocs ou dans les zones de grand intervalle entre deux éléments d'ossature successifs, des renforts locaux latéraux et longitudinaux sous la forme de longerons raidisseurs.The covering of the silo constitutes the wall interior proper of it, in contact direct with the material or products stored. In general, this covering is fixed on the framework or the frame by conventional means such as screws, rivets or the like, knowing that the inside of the covering must be as smooth as possible. In this method of construction, it is also necessary provide in places most exposed to shocks or in areas of large interval between two elements successive framework, local lateral reinforcements and longitudinal in the form of stiffening beams.

Ces modes traditionnels antérieurs de construction présentent de nombreux inconvénients notamment du point de vue constructif, et impliquent une intervention prépondérante de main d'oeuvre dans l'édification du silo, intervention alourdie par la pose de rigidificateurs latéraux ou longitudinaux.These earlier traditional fashions of construction have many drawbacks especially constructively, and involve a preponderant intervention of manpower in the construction of the silo, an intervention weighed down by the installation of lateral or longitudinal stiffeners.

On connaít par ailleurs par la publication du brevet français n° 2 658 171 au nom du déposant, un silo à enveloppe suspendue. Ce silo est constitué par une succession de formats de tôle accrochés par leurs bords supérieurs sur les éléments longitudinaux de l'ossature, et montés à recouvrement les uns sur les autres par leurs parties inférieures à la manière de tuiles ou de feuilles de bardage.We also know by the publication of French Patent No. 2,658,171 in the name of the applicant, a suspended envelope silo. This silo is made up of a succession of sheet metal formats hung by their upper edges on the longitudinal elements of the framework, and mounted overlapping one on the others by their lower parts in the manner of siding tiles or sheets.

Ce type de silo, par les gains de main d'oeuvre qu'il permet de réaliser, représente déjà une amélioration par rapport aux silos traditionnels. En effet, il suffit de poser à recouvrement les formats de tôle dont les bords supérieurs ont été préalablement conformés pour s'accrocher sur les éléments d'ossature. Il en résulte une pose simple et rapide pouvant être confiée à une main d'oeuvre peu qualifiée.This type of silo, by hand gains of work that it allows to realize, already represents a improvement over traditional elevators. In Indeed, it is enough to lay overlapping the formats of sheet metal whose upper edges have been previously shaped to hang on the frame elements. This results in a simple and rapid installation which can be entrusted to unskilled labor.

Ce type de silo peut néanmoins être encore amélioré dans certains de ses aspects constructifs.This type of silo can still be improved in some of its constructive aspects.

L'un de ces aspects concerne les bords des feuilles de tôle qui constituent des discontinuités de la surface intérieure du silo par des arêtes transversales. Les produits abrités dans le silo, directement en contact avec ces discontinuités, peuvent selon leur nature, s'endommager ou éventuellement être retenus par ces arêtes ou au voisinage de celles-ci. Ces discontinuités de la face intérieure du silo présentent également l'inconvénient de marquer les produits stockés lorsque ceux-ci sont réalisés en un matériau souple suffisamment déformable. Ce problème survient ainsi fréquemment lors du stockage par exemple de bouteilles en matière plastique qui, pour au moins une partie d'entre elles, ressortent souvent du silo marquées de stries ou de raies inesthétiques résultant de leur contact et friction avec les bords des feuilles de tôle. Cet inconvénient représentant un défaut d'aspect pour les consommateurs est jugé suffisamment sérieux pour que ce type de silo ne soit pas retenu par certains producteurs de boissons vendues dans des bouteilles en matière plastique transparente.One of these aspects concerns the edges of the sheet metal sheets which constitute discontinuities of the inside surface of the silo by edges transverse. The products housed in the silo, directly in contact with these discontinuities, can depending on their nature, being damaged or possibly being retained by these edges or in the vicinity thereof. These discontinuities on the inside of the silo also have the disadvantage of marking the products stored when these are made in one flexible material sufficiently deformable. This problem thus occurs frequently during storage for example plastic bottles which, for at least some of them often come out of the silo marked with unsightly streaks or lines resulting from their contact and friction with the edges of the leaves of sheet metal. This drawback representing a defect consumer-friendly enough serious so that this type of silo is not retained by certain producers of beverages sold in transparent plastic bottles.

Le second aspect se rapporte à la possible formation de passages linéaires entre deux formats de tôle successifs se recouvrant, et plus généralement à l'étanchéité de tels assemblages constructifs qui s'avère fréquemment insuffisante en raison des nombreuses possibilités d'entrée d'air et de poussières. Ainsi, ce type de silo s'avère inapproprié au stockage de matières en vrac, notamment de matières alimentaires.The second aspect relates to the possible formation of linear passages between two formats of successive sheets overlapping, and more generally at the watertightness of such constructive assemblies which is frequently insufficient due to numerous possibilities for air intake and dust. So, this type of silo turns out to be inappropriate storage of bulk materials, especially materials food.

La présente invention a pour but de remédier à ces inconvénients et propose à cet effet un procédé pour la constitution d'une paroi montée sur une charpente ou une ossature, par exemple la paroi d'un conteneur silo ou plus généralement l'enveloppe d'un volume quelconque à partir de la juxtaposition de formats successifs de feuilles de tôle.The object of the present invention is to remedy to these drawbacks and proposes a method for this purpose for the constitution of a wall mounted on a frame or framework, for example the wall of a silo container or more generally the envelope of a any volume from the juxtaposition of successive formats of sheet metal sheets.

L'invention concerne toutes les parois réalisées en feuilles de tôle notamment en tôle d'acier inoxydable, en matière plastique ou autre matière ou matériau. On peut citer à cet effet les parois de séparation, les parois de porte, les parois de protection et les parois d'isolation, mais aussi des parois de toit, des parois non planes, des habillages, bardages, blindages ou autres couvertures ou protections.The invention relates to all walls made of sheet metal, in particular sheet steel stainless, plastic or other material or material. We can cite for this purpose the walls of partition, the door walls, the walls of protection and insulation walls, but also roof walls, non-planar walls, claddings, siding, shielding or other coverings or protections.

Conformément au présent procédé, et selon sa caractéristique principale, on conforme par pliage les bords longitudinaux de chaque feuille de tôle selon un profil de réception et de calage, on réalise au moment de la confection de la charpente un canal rectiligne de réception des bords longitudinaux de chaque feuille, et on forme dans ce canal, de part et d'autre de celui-ci et à intervalles longitudinaux sur toute la longueur des feuilles, des zones de maintien sur lesquelles les deux bords longitudinaux en regard de deux feuilles adjacentes sont forcés latéralement l'un contre l'autre par des moyens de poussée, apportant une tension latérale aux feuilles de tôle, ces moyens de poussée se rétractant entre une position active de maintien des feuilles, et une position effacée inopérante dans laquelle lesdits bords des feuilles ne sont plus jointifs. On prévoit également en cas de nécessité des moyens procurant une tension longitudinale.In accordance with the present process, and according to its main characteristic, we conform by folding the longitudinal edges of each sheet of sheet metal according to a reception and setting profile, we realize at the moment of the construction of the frame a straight channel of receiving the longitudinal edges of each sheet, and we form in this channel, on both sides of it and at longitudinal intervals along the entire length sheets, support zones on which the two longitudinal edges opposite two sheets adjacent are forced laterally against each other by pushing means, bringing tension lateral to the sheet metal sheets, these thrust means retracting between an active position for maintaining leaves, and a cleared position inoperative in which said edges of the sheets are no longer joined. Provision is also made where necessary for means providing longitudinal tension.

La présente invention se rapporte aussi à une paroi ou une enveloppe extérieure obtenue par la mise en oeuvre du procédé ci-dessus, paroi ou enveloppe constituée de formats juxtaposés de feuilles de tôle habillant une ossature ou une charpente formée d'éléments horizontaux ou verticaux assemblés entre eux, caractérisée en ce que les bords longitudinaux de chaque feuille de tôle sont conformés en structures réceptrices et de calage, en ce que l'ossature présente des canaux rectilignes de réception des bords longitudinaux en regard de deux feuilles adjacentes, les canaux de réception comportant des zones de maintien par appui latéral l'un contre l'autre des deux bords en regard sous l'effet de moyens antagonistes et effaçables de poussée, et en ce que les bords longitudinaux sont forcés et plaqués latéralement l'un contre l'autre par ces moyens.The present invention also relates to a wall or an outer envelope obtained by placing using the above process, wall or envelope made up of formats juxtaposed with sheet metal sheets covering a framework or a formed frame horizontal or vertical elements assembled between them, characterized in that the longitudinal edges of each sheet of sheet metal is shaped into structures receiving and wedging, in that the framework has straight channels for receiving edges longitudinal facing two adjacent sheets, the reception channels comprising zones of support by lateral support one against the other of the two opposite edges under the effect of antagonistic means and erasable by push, and in that the edges longitudinal are forced and laterally plated one against the other by these means.

Des moyens de tension longitudinale sont en outre prévus pour les tôles fines.Longitudinal tensioning means are in additionally provided for thin sheets.

La présente invention se rapporte également à un objet ou un produit plus élaboré ou étendu comme par exemple un silo et plus généralement un conteneur, un abri, un bâtiment ou autres réalisations mettant en oeuvre une ossature et une couverture.The present invention also relates to a more elaborate or extended object or product such as example a silo and more generally a container, a shelter, building or other construction frame and cover.

Selon un de ses avantages, la présente invention permet d'éviter la présence de bords transversaux notamment en saillie de la surface intérieure du silo, et donc les risques correspondants de retenue et de marquage des produits contenus dans le silo.According to one of its advantages, the present invention avoids the presence of edges transverse in particular projecting from the surface inside the silo, and therefore the corresponding risks of restraint and marking of the products contained in the silo.

D'autres avantages sont à mentionner :

  • la tôle n'est ni percée ni interrompue brusquement. La jonction des bords s'effectue dans le même plan que celui de la tôle ;
  • l'absence totale de joints évite la contamination bactériologique ;
  • dans le cas d'un silo, l'étanchéité relative permet de viser de nombreuses applications, notamment les silos pressurisés ;
  • l'étanchéité relative peut être renforcée par des bords longitudinaux à formes encastrables simples ou multiples ;
  • la tension latérale permanente de la tôle associée le cas échéant à une tension longitudinale assure une rigidité suffisante et par conséquent la possibilité d'utiliser des feuilles de tôle de moindre épaisseur et d'éviter l'emploi de rigidificateurs rapportés, soudés par points ou vissés ;
Other advantages are worth mentioning:
  • the sheet is neither pierced nor abruptly interrupted. The edges are joined in the same plane as that of the sheet metal;
  • the total absence of joints avoids bacteriological contamination;
  • in the case of a silo, the relative tightness makes it possible to target numerous applications, in particular pressurized silos;
  • the relative tightness can be reinforced by longitudinal edges with simple or multiple recessed shapes;
  • the permanent lateral tension of the sheet associated with a longitudinal tension if necessary ensures sufficient rigidity and therefore the possibility of using sheets of thin sheet metal and avoiding the use of added stiffeners, spot welded or screwed ;

Mais l'invention trouve toute sa valeur dans la réduction notable du coût de la main d'oeuvre nécessaire à l'édification d'une paroi, d'une enveloppe ou d'un ensemble formé à base de parois par exemple mais non limitativement d'un silo de par la durée réduite de montage et la possibilité d'employer une main d'oeuvre non qualifiée.But the invention finds its full value in significant reduction in the cost of labor necessary for the construction of a wall, an envelope or a set formed from walls for example but not limited to a silo by duration reduced mounting and the possibility of using a unskilled labor.

Elle permet également d'améliorer sensiblement l'étanchéité à l'air des ensembles constructifs ainsi constitués en évitant le chevauchement des formats de feuilles de tôle.It also improves substantially airtightness of the assemblies thus constituted by avoiding the overlapping sheet metal sheet formats.

La présente invention se rapporte de façon générale à un silo formé à partir de feuilles de tôle juxtaposées et immobilisées sur une ossature ou une charpente extérieure et à son procédé de construction. Pour mieux faire comprendre cette invention, on décrira d'abord la constitution d'une paroi et cette paroi à face intérieure lisse à partir d'une ossature extérieure et de feuilles de tôle montées juxtaposées et immobilisées par pincement sur cette ossature en plusieurs endroits sur toute leur hauteur avec tension latérale complétée au besoin par une tension longitudinale.The present invention relates so general to a silo formed from sheet metal sheets juxtaposed and immobilized on a frame or exterior frame and its construction process. To better understand this invention, we will describe first the constitution of a wall and this wall to smooth inside from a frame exterior and sheet metal sheets mounted juxtaposed and immobilized by pinching on this frame in several places over their entire height with tension lateral supplemented if necessary by tension longitudinal.

On débutera la description par celle d'une paroi de base ou élémentaire non finie en hauteur. Il est évident que cette paroi élémentaire se répétera latéralement pour constituer la surface latérale du silo et sa couverture.We will start the description with that of a base or elementary wall not finished in height. he is obvious that this elementary wall will repeat itself laterally to form the lateral surface of the silo and its cover.

Une ossature destinée par exemple à constituer la charpente 1 d'un silo ou autre volume fermé de stockage est construite à partir de longerons tels que 2 et 3 et de profilés verticaux ou poteaux d'ossature tels que 4 solidarisés entre eux par soudage ou assemblés par des moyens mécaniques.A framework intended for example for constitute the frame 1 of a silo or other volume closed storage is constructed from spars such as 2 and 3 and vertical profiles or posts of framework such as 4 joined together by welding or assembled by mechanical means.

Ces profilés assemblés servent de support à des formats adjacents de feuilles de tôle juxtaposées 5, 6 en général de grande longueur.These assembled profiles are used to support adjacent formats of juxtaposed sheet metal sheets 5, 6 generally very long.

Sont prévus dans l'ossature à intervalles horizontaux déterminés par la largeur de la tôle, des canaux rectilignes verticaux de réception tels que 7 (figure 4) et dans ces canaux, à intervalles verticaux, fonction de la rigidité à obtenir, des zones transversales de maintien telles que 8 de deux feuilles de tôle adjacentes 5,6. Dans ces zones de l'ossature, deux feuilles de tôle adjacentes 5,6 présentant des bords longitudinaux homologues 9,10 sont appliquées l'une contre l'autre par lesdits bords longitudinaux disposés en regard, et maintenues dans cette position un bord plaqué contre l'autre par des forces opposées provenant de moyens antagonistes transversaux mobiles de poussée 11, 12.Are provided in the frame at intervals horizontal determined by the width of the sheet, vertical straight receiving channels such as 7 (Figure 4) and in these channels, at vertical intervals, depending on the stiffness to be obtained, the zones holding crosses such as 8 of two sheets of adjacent sheets 5.6. In these areas of the framework, two adjacent sheets of sheet 5.6 having homologous longitudinal edges 9.10 are applied one against the other by said longitudinal edges arranged opposite, and held in this position one edge pressed against the other by opposing forces from mobile transverse antagonistic means thrust 11, 12.

A cet effet, les bords longitudinaux 9 et 10 en regard de deux feuilles de tôle adjacentes sont profilés selon des formes réceptrices homologues et juxtaposées 13 et 14 qui permettront leur calage-immobilisation par les moyens de poussée 11 et 12 agissant en rappel antagoniste de poussée.For this purpose, the longitudinal edges 9 and 10 next to two adjacent sheets of sheet metal are shaped according to homologous receiving shapes and juxtaposed 13 and 14 which will allow their setting-immobilization by the pushing means 11 and 12 acting as an antagonistic pushback.

Ces bords longitudinaux 9,10 peuvent être conformés de différentes façons comme on le verra en détail ultérieurement. Pour la variante d'exécution préférée de l'invention, ces formes réceptrices 13 et 14 se présentent sous la forme d'ailes longitudinales telles que 15 formées chacune d'un plan d'appui 16 obtenu par pliage d'équerre du bord de la feuille suivi d'un retour de calage 17 obtenu également par pliage d'équerre, mais perpendiculairement au plan d'appui.These longitudinal edges 9,10 can be conformed in different ways as we will see in detail later. For the variant preferred of the invention, these receptor forms 13 and 14 are in the form of longitudinal wings such as 15 each formed of a support plane 16 obtained by square bending of the edge of the sheet followed a timing return 17 also obtained by folding square, but perpendicular to the support plane.

Ces bords longitudinaux convenablement conformés coopèrent dans chaque zone transversale de maintien 8 avec les moyens de poussée 11 et 12 réalisés selon la variante préférée sous la forme de moyens d'immobilisation effaçables par exemple par rétraction et montés en rappel de poussée vers la forme réceptrice 13 ou 14 qui entoure leur extrémité frontale.These longitudinal edges suitably conformed cooperate in each transverse area of holding 8 with the pushing means 11 and 12 produced according to the preferred variant in the form of means erasable immobilizers for example by retraction and mounted as a push back to the receiving form 13 or 14 which surrounds their front end.

Il existe au niveau de chaque zone transversale de maintien 8 de deux bords longitudinaux 9 et 10 à rendre jointifs par appui-pincement, deux pièces mobiles de maintien 18 et 19 des moyens de poussée 11 et 12 montés en rappel élastique de poussée l'un vers l'autre. There are at the level of each zone transverse holding 8 of two longitudinal edges 9 and 10 to be joined by pinch support, two moving parts 18 and 19 for holding means thrust 11 and 12 mounted in elastic thrust return towards each other.

Plus particulièrement, ces zones de maintien 8 sont prévues dans et le long de chaque canal vertical de réception dont le fond est délimité par un profilé vertical 4. Ce canal 7 forme un logement pour les deux bords longitudinaux 9 et 10 en regard de deux feuilles adjacentes 5 et 6. Les zones transversales de maintien 8 sont prévues à intervalles verticaux et sont équipées chacune d'un des deux moyens de poussée 11 ou 12 sous la forme de deux verrous disposés en regard l'un de l'autre dont les pièces mobiles 18 et 19 remplissant la fonction de pênes effaçables, sont montées en rappel de poussée l'une vers l'autre pour forcer les plans d'appui 16 des deux bords longitudinaux adjacents en contact l'un contre l'autre et procurer ainsi une étanchéité minimale relative.More particularly, these holding zones 8 are provided in and along each vertical channel reception whose bottom is delimited by a profile vertical 4. This channel 7 forms a housing for both longitudinal edges 9 and 10 opposite two sheets adjacent 5 and 6. The transverse holding zones 8 are provided at vertical intervals and are equipped each of one of the two pushing means 11 or 12 under the shape of two locks arranged opposite one of the other whose moving parts 18 and 19 filling the function of erasable bolts, are mounted as a reminder of pushed towards each other to force plans support 16 of the two adjacent longitudinal edges at contact one against the other and thus provide a relative minimum tightness.

La figure 10 illustre par des flèches le passage de l'air entre les bords jointifs permettant ainsi de réaliser les sorties d'air nécessaires dans le cas d'un conteneur, par exemple, un silo pressurisé.Figure 10 illustrates with arrows the air passage between the contiguous edges allowing thus achieving the necessary air outlets in the case of a container, for example, a pressurized silo.

Cette étanchéité relative peut être améliorée en conformant les plans d'appui 16 selon des formes complémentaires par poinçonnage, profilage ou toute autre technique de déformation du métal à chaud ou à froid. Il peut s'agir de formes complémentaires en "U" (figure 14) en "V" (figure 15) ou en "C" couché simple (figure 16) ou double (figure 17) ou autre forme adaptée par simplification ou duplication ou multiplication des formes indiquées ou toute autre forme appropriée.This relative tightness can be improved conforming the support planes 16 according to shapes complementary by punching, profiling or any other hot or hot metal deformation technique cold. They can be complementary "U" shapes (figure 14) in "V" (figure 15) or in "C" lying single (figure 16) or double (figure 17) or other form adapted by simplification or duplication or multiplication of the indicated forms or any other appropriate form.

Dans la réalisation représentée, les pièces mobiles de maintien 18,19 jouent chacune le rôle d'un pêne de verrou sans blocage de mouvement.In the illustrated embodiment, the pieces 18.19 holding mobiles each play the role of a latch bolt without movement blocking.

Chaque pêne constituant une pièce mobile 18 ou 19 est, par exemple, de forme générale parallélépipédique avec un front avant de poussée 20 de différentes formes, par exemple droit et plat avec ou sans décrochement 21 ou biseauté 22 ou avec un méplat 23 par exemple central ou toute autre forme adaptée comme représenté sur les figures de 11 à 13. La face arrière de ces pièces de poussée est prolongée par une queue 24 sous la forme d'une tige sur laquelle est enfilé un ressort hélicoïdal 25 bloqué d'un côté par le front arrière 26 du pêne et de l'autre par une patte de fixation-maintien 27 fixée au corps du longeron adjacent 2 ou 3 d'ossature. La patte de maintien 27 est traversante pour la tige 24 qui dépasse de son passage, même en position complètement sortie du pêne. La course du pêne est de préférence limitée en état d'extension du ressort par une butée latérale (non représentée).Each bolt constituting a moving part 18 or 19 is, for example, of general shape parallelepipedic with a front of push 20 of different shapes, for example straight and flat with or without recess 21 or beveled 22 or with a flat 23 for example central or any other suitable form as shown in Figures 11 to 13. The face rear of these thrust pieces is extended by a tail 24 in the form of a rod on which is threaded a coil spring 25 blocked on one side by the rear edge 26 of the bolt and of the other by a lug fixing-holding 27 fixed to the body of the spar adjacent 2 or 3 framework. The retaining tab 27 is through for the rod 24 which protrudes from its passage, even in the fully extended position. The race of the bolt is preferably limited in the extended state of the spring by a lateral stop (not shown).

Conformément à la variante représentée, chaque pêne est guidé en translation par trois parois adjacentes successives du longeron adjacent 2,3 d'ossature délimitant avec le profilé vertical adjacent une ouverture 28 pour la sortie du pêne.According to the variant shown, each bolt is guided in translation by three walls successive adjacent adjacent beam 2,3 of framing delimiting with the adjacent vertical profile an opening 28 for the exit of the bolt.

Bien entendu, d'autres particularités constructives à la portée de l'homme du métier peuvent être imaginées pour les moyens de poussée, pour le pêne, pour son logement pour la réalisation de l'ouverture 28 de passage ou pour la confection des zones de maintien.Of course, other peculiarities within the reach of those skilled in the art can be imagined for the means of thrust, for the bolt, for its housing for the realization of opening 28 for passage or for making holding zones.

La figure 9 montre schématiquement par des flèches et lignes en traits brisés le léger bombé 29 des tôles lorsqu'elles ne sont pas tendues latéralement, c'est-à-dire quand les bords longitudinaux adjacents 9 et 10 ne sont pas jointifs. Cette figure montre également la possible intromission d'une canule 30 de nettoyage entre les deux bords préalablement écartés à l'aide d'un outil 31 par exemple à extrémité plate 32 (figure 8).Figure 9 shows schematically by arrows and broken lines dashed light 29 sheets when they are not stretched laterally, i.e. when the edges adjacent longitudinal 9 and 10 are not contiguous. This figure also shows the possible intromission a cleaning cannula 30 between the two edges previously removed using a tool 31 by example with flat end 32 (FIG. 8).

Le procédé de montage d'une paroi ou analogue consiste d'une part à former et à conformer des bords longitudinaux dans un format de tôle sous forme de feuilles 5,6 dont la longueur est préférentiellement la hauteur de l'objet final et d'autre part à construire une ossature ou une charpente 1 à partir de longerons 2,3 et de profilés verticaux 4 en ménageant à intervalles longitudinaux et transversaux des zones de maintien 8 le long des canaux de réception 7 formant un logement pour les bords longitudinaux 9,10 des feuilles de tôle, zones de maintien 8 dans lesquelles les bords en regard des feuilles de tôle sont appliqués l'un contre l'autre par des forces contraires d'appui dirigées l'une et l'autre vers le plan d'appui du bord correspondant et l'une vers l'autre par des moyens de poussée 11,12.The method of mounting a wall or the like on the one hand consists of forming and shaping edges longitudinal in sheet metal format as sheets 5,6 whose length is preferably the height of the final object and secondly to build a frame or a frame 1 from longitudinal members 2,3 and vertical sections 4, while providing longitudinal and transverse intervals of the zones of holding 8 along the reception channels 7 forming a space for the longitudinal edges 9.10 of the sheets sheet metal, holding zones 8 in which the edges next to the sheet metal sheets are applied one against each other by opposing support forces both directed towards the edge support plane corresponding and to each other by means of thrust 11.12.

Selon la variante préférée, ces forces sont des forces élastiques de rappel dans une position de contact-poussée des bords longitudinaux 9,10 de chaque feuille de tôle 5,6 l'un contre l'autre.According to the preferred variant, these forces are elastic restoring forces in a position of push-contact of the longitudinal edges 9.10 of each sheet metal 5.6 against each other.

Plus particulièrement, on conforme les bords longitudinaux 9,10 de la feuille de tôle par pliage d'équerre selon un plan d'appui 16 suivi d'un retour 17 de calage également par pliage d'équerre. Cette forme réceptrice est montée sur chaque pièce mobile 18,19 des moyens de poussée 11,12, on monte ensuite de la même façon la forme réceptrice adjacente sur la pièce mobile opposée. Ces forces élastiques contraires poussent les pièces mobiles l'une contre l'autre en appuyant par l'arrière sur les bords adjacents des feuilles de tôle 5,6.More particularly, we conform the edges 9.10 longitudinal sheets of sheet metal by folding square according to a support plane 16 followed by a return 17 also for wedging by square bending. This shape receiver is mounted on each moving part 18.19 of pushing means 11,12, then ascended by the same way the adjacent receiving shape on the moving part opposite. These opposite elastic forces push the moving parts against each other by pressing the back on the adjacent edges of the sheet metal sheets 5.6.

Le maintien transversal de chaque feuille de tôle est assuré ainsi par appui-pincement d'un bord 9 sur l'autre 10 à intervalles réguliers ou non, sur toute sa longueur, mais suffisamment rapprochés pour obtenir par une tension latérale l'effet de maintien et de rigidification recherché.The transverse maintenance of each sheet of sheet metal is ensured thus by pinch-support of an edge 9 on the other 10 at regular intervals or not, on its entire length, but close enough to obtain by a lateral tension the holding effect and stiffening sought.

En cas de besoin, on engendre par des moyens spécifiques non représentés une force de traction qui procure une tension longitudinale qui, associée à la tension latérale, permet de conférer aux tôles minces la rigidité nécessaire. If necessary, we generate by means specific not shown a tensile force which provides longitudinal tension which, associated with lateral tension, allows to give thin sheets the necessary rigidity.

Cette technique permet d'utiliser des feuilles de tôle plus minces car la tension latérale provenant des efforts de poussée dans les zones de maintien procure une rigidité suffisante pour le maintien du contenu par exemple d'un silo ou résister à toute autre poussée sur une paroi en utilisation normale.This technique allows the use of thinner sheet metal because the lateral tension from pushing efforts in areas of support provides sufficient rigidity for the content maintenance for example of a silo or resist any other thrust on a wall in use normal.

Il faut mentionner de plus, l'extraordinaire rapidité et facilité de montage, mais aussi de déboítement ou de déchaussement des bords des feuilles de tôle. Il suffit d'insérer un instrument ou un outil 31 à l'extrémité plate 32 ou une tige plate, ou l'extrémité d'un tournevis dans l'étroite fente existant entre deux feuilles successives 5,6 pour, après un quart de tour, arriver à écarter suffisamment les bords jointifs pour ensuite passer le bec ou la buse de pulvérisation, d'aspersion ou de diffusion 30 d'un appareil de nettoyage et/ou de désinfection.We must also mention, the extraordinary speed and ease of assembly, but also dislocation or loosening of the edges of the leaves of sheet metal. Just insert an instrument or tool 31 at the flat end 32 or a flat rod, or the end of a screwdriver in the narrow slot existing between two successive sheets 5.6 for, after a quarter turn, manage to spread enough the contiguous edges to then pass the beak or the spray, sprinkler or diffusion nozzle 30 a cleaning and / or disinfection device.

Le procédé selon l'invention confère une rapidité exceptionnelle de montage-démontage d'une paroi ou analogue pouvant être exécuté par un personnel non qualifié. Le coût total de la main d'oeuvre pour l'édification d'une paroi ou analogue est ramené à un montant beaucoup plus faible en réduisant le taux horaire et la durée totale nécessaire au montage.The method according to the invention gives a exceptional speed of assembly-disassembly of a wall or the like capable of being executed by personnel non qualified. The total cost of labor for the construction of a wall or the like is reduced to a much lower amount by reducing the rate hours and the total time required for assembly.

On décrira maintenant plus particulièrement un conteneur du type silo constituant un exemple type d'application de l'invention en se référant aux figures 18, 19 et 20.We will now describe more particularly a silo type container constituting a typical example of application of the invention with reference to the figures 18, 19 and 20.

Comme on peut le constater sur ces figures, le silo présente une surface latérale 33 qui est constituée de parois longitudinales 34 et de parois transversales 35 formées chacune d'une succession latérale en juxtaposition de feuilles de tôle dont les bords longitudinaux sont conformés selon les formes indiquées ci-dessus.As can be seen in these figures, the silo has a lateral surface 33 which is made up of longitudinal walls 34 and walls 35 transverse each formed of a succession side in juxtaposition of sheet metal sheets whose longitudinal edges are shaped according to the shapes indicated above.

Ces feuilles sont juxtaposées et assemblées entre elles contre les poteaux d'ossature ou de charpente par calage-immobilisation et appui-pincement d'un bord sur l'autre à l'aide des moyens de poussée 11 et 12 antagonistes formant deux verrous opposés.These sheets are juxtaposed and assembled between them against the studs of framework or frame by wedging-immobilization and pinch support from one edge to the other using the pushing means 11 and 12 antagonists forming two opposite locks.

Ces feuilles de tôle sont réunies entre elles aux angles par l'intermédiaire de poteaux d'angle tels que 36.These sheet metal sheets are joined together at the corners by means of corner posts such than 36.

Cette constitution est celle courante des parois formant la surface latérale 33, mais aussi la constitution du fond 37 et de structure supérieure de couverture 38 que l'on examinera maintenant.This constitution is the current one for walls forming the lateral surface 33, but also the constitution of the bottom 37 and upper structure of cover 38 which we will now examine.

La structure supérieure de couverture 38 est représentée en détail sur la figure 19.The upper cover structure 38 is shown in detail in Figure 19.

Elle est formée d'un réseau 39 de longerons supérieurs 40 et de traverses supérieures 41 formant une armature horizontale sur laquelle est montée en sous face la juxtaposition de feuilles de tôle à bords longitudinaux pliés maintenues par les verrous prévus pour les parois de surface latérale. Ce réseau 39 est raccordé à la partie supérieure des parois 34 et 35 de surface latérale de la façon suivante. Le chant supérieur 42 de chaque paroi de surface latérale est formé par la succession des faces supérieures des profilés horizontaux et des extrémités des poteaux d'ossature délimitant entre eux les canaux de réception 7. Les chants supérieurs 42 des parois longitudinales 34 de surface latérale sont fermés par un profilé en tube plat 43 disposé à plat formant également une bordure mécanique et de propreté. Ce profilé de bordure 43 est solidarisé au longeron supérieur 40 adjacent de la structure supérieure de couverture 38 apparaissant sur les figures 18 et 19.It is made up of a network 39 of spars upper 40 and upper sleepers 41 forming a horizontal frame on which is mounted in underside the juxtaposition of sheet metal sheets with edges longitudinal folds held by the provided latches for side surface walls. This network 39 is connected to the upper part of the walls 34 and 35 of lateral surface as follows. Singing upper 42 of each side surface wall is formed by the succession of the upper faces of horizontal profiles and ends of posts frame delimiting between them the reception channels 7. The upper edges 42 of the longitudinal walls 34 of lateral surface are closed by a profile in flat tube 43 arranged flat also forming a mechanical and cleanliness border. This border profile 43 is secured to the adjacent upper beam 40 of the upper cover structure 38 appearing in Figures 18 and 19.

Le raccordement de jonction à l'arête de deux parois consécutives de surface latérale est réalisé conformément à la figure 21 autour d'un poteau d'angle 36 flanqué sur chacune de ses surfaces latérales côté intérieur par des profilés verticaux tubulaires d'appui 44 et 45 dont la longueur, posés à plat, est inférieure aux côtés du poteau d'angle 36 de façon à ménager chacun un espace 46 adapté pour l'appui-calage du bord longitudinal 9 ou 10 de chaque feuille de tôle d'extrémité de paroi latérale. Cette structure est symétrique par rapport au poteau d'angle 36.The junction connection at the edge of two consecutive side surface walls is realized as shown in figure 21 around a corner post 36 flanked on each of its side side surfaces inside by vertical tubular support profiles 44 and 45 whose length, laid flat, is less alongside the corner post 36 so as to spare each a space 46 adapted for the bracing support of the edge longitudinal 9 or 10 of each sheet side wall end. This structure is symmetrical about the corner post 36.

Le fond 37 du silo présente une paroi horizontale 47 ou inclinée 48. Les jonctions de raccordement de ce fond s'effectuent de façon différente selon qu'il s'agit d'un fond horizontal (figure 22) ou d'un fond incliné (figure 23).The bottom 37 of the silo has a wall horizontal 47 or inclined 48. The junctions of connection of this bottom is done so different depending on whether it is a horizontal background (Figure 22) or an inclined bottom (Figure 23).

Dans le cas d'un fond à paroi horizontale 47, le raccordement du fond 37 avec un profilé de la bordure inférieure 49 s'effectue de façon identique au raccordement avec le poteau d'angle 36 avec pincement du bord inférieur de la feuille verticale adjacente par le bord longitudinal 9,10 de la feuille de fond contre le profilé de bordure.In the case of a bottom with a horizontal wall 47, the connection of the bottom 37 with a profile of the lower border 49 is carried out identically to connection with corner post 36 with pinch from the lower edge of the adjacent vertical sheet by the longitudinal edge 9.10 of the backsheet against the edge profile.

Un profilé tubulaire 45 ménage un espace 46 comme dans le cas du raccordement sur poteau d'angle 36.A tubular profile 45 saves space 46 as in the case of connection on corner post 36.

Le raccordement dans le cas d'un fond incliné 48 s'effectue de façon plus complexe. La bordure inférieure 49 est réalisée par deux profilés 50 et 51 formant une section en L renversé. La paroi 48 du fond incliné vient se caler en biais contre le profilé vertical 51 de la bordure inférieure 49 à l'aide d'un support annexe d'extrémité 52 du type cornière à angle ouvert solidarisé au profilé de bordure 49 de la paroi de fond. Les feuilles de tôle de la paroi latérale adjacente et de la paroi inclinée 48 de fond viennent en contact d'étanchéité par leurs extrémités. On remarque par exemple pour la feuille de la paroi latérale une extrémité 53 pliée en équerre et pour la feuille de la paroi de fond une extrémité en saillie de porte-à-faux.The connection in the case of an inclined bottom 48 is more complex. The border lower 49 is produced by two sections 50 and 51 forming an inverted L-shaped section. The rear wall 48 inclined is wedged against the profile vertical 51 of the lower border 49 using a annex end support 52 of the angle angle type open secured to the edge profile 49 of the wall background. Sheet metal sheets of the side wall adjacent and from the inclined bottom wall 48 come in sealing contact by their ends. We note for example for the wall sheet lateral one end 53 folded square and for the sheet of the bottom wall one end protruding from cantilevered.

On a décrit ci-dessus un conteneur du type silo, de forme conventionnelle à fond horizontal ou incliné. Il est bien entendu que diverses autres formes et autres types de conteneurs sont possibles en utilisant la même technique de construction et de constitution.We have described above a container of the type silo, of conventional shape with horizontal bottom or inclined. It is understood that various other forms and other types of containers are possible in using the same construction technique and constitution.

A titre additionnel, mais uniquement en cas de besoin impératif, l'invention prévoit un moyen supplémentaire permettant de créer une tension longitudinale des feuilles de tôle. Ce besoin est ressenti plus particulièrement dans le cas de tôles plus fines.Additionally, but only in the event of imperative need, the invention provides a means additional to create tension sheet metal sheets. This need is felt more particularly in the case of sheets thinner.

Ce moyen d'établissement d'une force permanente de tension longitudinale peut se concrétiser sous différentes formes de réalisation.This means of establishing a force longitudinal tension can materialize in different embodiments.

Cette mise en tension ou rigidification existe dans le cas d'une paroi de séparation 54 du silo représentée sur la figure 20. Cette paroi de séparation 54 est formée par la succession latérale de plusieurs feuilles de tôle 55,56 à bords longitudinaux 57,58 pliés et imbriqués l'un dans l'autre de façon à former un logement longitudinal vertical plat 59 occupé par une âme ou une fourrure métallique 60 sous forme d'un fer plat remplissant la fonction de raidisseur ou de rigidificateur.This tensioning or stiffening exists in the case of a partition wall 54 of the silo shown in Figure 20. This partition wall 54 is formed by the lateral succession of several sheet metal sheets 55.56 with longitudinal edges 57.58 folded and nested one inside the other so as to form a flat vertical longitudinal housing 59 occupied by a soul or a metallic fur 60 in the form of a flat iron performing the function of stiffener or stiffener.

Chaque raidisseur 60 provoque la mise en tension de la feuille de tôle par un moyen de traction. Ce moyen de traction peut être réalisé par exemple sous la forme de tiges filetées de traction 61 qui traversent chacune un support de liaison 62 réunissant à intervalles les deux poutres 63 et 64 d'un longeron transversal disposé au-dessus de la cloison transversale de séparation 54. L'extrémité inférieure de chaque tige filetée est solidarisée à l'extrémité supérieure de chaque raidisseur 60. Sur le corps de la tige filetée est prévu un ensemble écrou-rondelle 65 qui prend appui sur la face supérieure du support transversal de liaison 62 traversé par la tige filetée 61 pour donner naissance à un effort vertical de mise en tension réglable par la position de l'écrou.Each stiffener 60 causes the setting tension of the sheet metal sheet by means of traction. This traction means can be produced for example under the form of threaded pull rods 61 which each pass through a connecting support 62 bringing together at intervals the two beams 63 and 64 of a beam transverse arranged above the partition dividing cross 54. The lower end of each threaded rod is secured at the end upper of each stiffener 60. On the body of the threaded rod is provided with a nut-washer assembly 65 which is supported on the upper face of the support transverse link 62 crossed by the threaded rod 61 to give birth to a vertical effort of setting tension adjustable by the position of the nut.

Cette tension se transmet à la feuille de tôle adjacente car chaque raidisseur 60 est immobilisé par rapport à celle-ci au moyen de deux boulons ou vis 66,67 à extrémité fraisée.This tension is transmitted to the sheet of adjacent sheet because each stiffener 60 is immobilized relative to it by means of two bolts or screws 66.67 with milled end.

Ce moyen de mise en tension associé à chaque raidisseur 60 est représenté dans le cas d'une paroi de séparation 54. Il est bien entendu qu'il peut être utilisé également pour les parois longitudinales 34 et transversales 35 de surface latérale du silo.This means of tensioning associated with each stiffener 60 is shown in the case of a wall of separation 54. It is understood that it can be also used for the longitudinal walls 34 and transverse 35 of lateral surface of the silo.

Le raccordement de la cloison de séparation 54 avec la surface latérale s'effectue de la façon suivante.The connection of the partition wall 54 with the side surface is done in the way next.

Les bords longitudinaux des feuilles de tôle d'extrémité sont repliés et maintenus au niveau d'une jonction d'assemblage 68 de la surface latérale. La surépaisseur représentée par le pli rabattu 69 du bord vertical de la feuille 55 vient se loger entre deux poteaux d'ossature 4 disposés en regard. La feuille de tôle d'extrémité 55 de la paroi de séparation 54 passe entre les deux bords longitudinaux opposés 9 et 10 de deux feuilles de tôle voisines de surface latérale et se trouve maintenue par pincement-immobilisation entre ces bords suite aux forces antagonistes provenant des moyens de poussée. Le maintien de la paroi est amélioré par la présence d'une bordure inférieure oblique 70 formée de deux profilés tubulaires parallèles 71 et 72 entre lesquels la tôle se trouve pincée par des moyens de rapprochement et de serrage par exemple des boulons (non représentés).Longitudinal edges of sheet metal sheets ends are folded and held at a level joining junction 68 of the lateral surface. The extra thickness represented by the folded fold 69 of the edge vertical of the sheet 55 is housed between two framework posts 4 arranged facing each other. The sheet of end plate 55 of the partition wall 54 pass between the two opposite longitudinal edges 9 and 10 of two adjacent sheet metal sheets of lateral surface and is held by pinch-immobilization between these edges following the antagonistic forces coming from means of pushing. Wall retention is improved by the presence of an oblique lower border 70 formed of two parallel tubular sections 71 and 72 between which the sheet is pinched by means for tightening and tightening, for example bolts (not shown).

Le procédé de constitution et d'édification d'un silo selon l'invention consiste d'une part à construire à partir de longerons horizontaux 2,3 et de poteaux d'ossature 4 une ossature ou une charpente extérieure 1 en respectant les distances entre les extrémités des longerons horizontaux pour créer des canaux de réception 7 destinés à former un logement pour les bords longitudinaux 9,10 des feuilles de tôle et d'autre part à poser les verrous des moyens de poussée 11 et 12 et à mettre en place les feuilles de tôle. La longueur de celles-ci est choisie au moins égale à la hauteur des parois de surface latérale.The constitution and edification process of a silo according to the invention consists on the one hand in build from horizontal beams 2,3 and frame posts 4 a frame or a frame outside 1 respecting the distances between ends of the horizontal beams to create receiving channels 7 intended to form a housing for the longitudinal edges 9.10 of the sheet metal sheets and on the other hand to put the locks on the means of push 11 and 12 and to put up the sheets of sheet metal. The length of these is chosen at least equal to the height of the side surface walls.

On effectue ensuite les raccordements au niveau des poteaux d'angle 36 et les raccordements inférieurs entre les parois de surface latérale et la paroi de fond.Then we make the connections to the level of corner posts 36 and connections between the side surface walls and the back wall.

S'il est souhaité une structure supérieure de couverture, on procède à la pose de la bordure périmétrique supérieure par un profilé tubulaire plat au-dessus du chant supérieur 42 des parois latérales longitudinales 34. On construit ensuite la structure supérieure de couverture 38 de la même façon que les parois de surface latérale et on y pose les feuilles de tôle puis on les immobilise en utilisant les verrous de poussée.If a higher structure of cover, we proceed with the installation of the border upper perimeter by a flat tubular profile above the upper edge 42 of the side walls 34. We then build the structure cover 38 in the same way as the side surface walls and put the sheets of sheet metal then they are immobilized using the locks thrust.

Au besoin, on monte une cloison de séparation 54 sans poteaux verticaux, mais en utilisant des raidisseurs 60 reliés à un longeron supérieur 63,64 par un moyen de mise en tension des feuilles de tôle.If necessary, install a partition 54 without vertical posts, but using stiffeners 60 connected to an upper beam 63.64 by a means of tensioning the sheet metal sheets.

En ce qui concerne les feuilles de tôle, on conforme les bords longitudinaux 9,10 de celles-ci par pliage d'équerre selon un plan d'appui 16 suivi d'un retour 17 de calage également par pliage d'équerre. Cette forme réceptrice est montée sur chaque pièce mobile 18,19 des verrous, on monte ensuite de la même façon la forme réceptrice adjacente sur la pièce mobile opposée. Ces forces élastiques contraires poussent les pièces mobiles l'une contre l'autre en appuyant par l'arrière sur les bords adjacents des feuilles de tôle 5,6.Regarding sheet metal sheets, we conforms to the longitudinal edges 9.10 of these by square folding according to a support plane 16 followed by a back 17 also wedging by folding angle. This receiving form is mounted on each piece mobile 18.19 locks, then mounted in the same way way the adjacent receiving shape on the moving part opposite. These opposite elastic forces push the moving parts against each other by pressing the back on the adjacent edges of the sheet metal sheets 5.6.

Le maintien transversal de chaque feuille de tôle est assuré ainsi par appui-pincement d'un bord 9 sur l'autre 10 à intervalles réguliers ou non, sur toute sa longueur, mais suffisamment rapprochés pour obtenir par une tension latérale l'effet de maintien et de rigidification recherché.The transverse maintenance of each sheet of sheet metal is ensured thus by pinch-support of an edge 9 on the other 10 at regular intervals or not, on its entire length, but close enough to obtain by a lateral tension the holding effect and stiffening sought.

Comme indiqué, en cas de besoin, on engendre par des moyens spécifiques dont un exemple appliqué à une cloison de séparation a été représenté une force de traction procurant une tension longitudinale qui, associée à la tension latérale, permet de conférer aux tôles minces la rigidité nécessaire.As indicated, if necessary, we generate by specific means including an example applied to a partition was shown a force of traction providing longitudinal tension which, associated with lateral tension, allows to give thin sheets the necessary rigidity.

Cette technique permet d'utiliser des feuilles de tôle plus minces car la tension latérale provenant des efforts de poussée des verrous dans les zones de maintien procure une rigidité suffisante pour le maintien du contenu du silo.This technique allows the use of thinner sheet metal because the lateral tension from the pushing efforts of the locks in the holding zones provides sufficient rigidity to maintaining the content of the silo.

Il faut mentionner de plus, l'extraordinaire rapidité et facilité de montage des verrous aux emplacements prévus sur les éléments de charpente ou d'ossature extérieure mais aussi la simplicité de pose des feuilles de tôle. Le démontage ou la dépose s'avèrent tout aussi simples et rapides. Pour procéder au déboítement ou au déchaussement des bords des feuilles de tôle, il suffit d'insérer un instrument ou un outil 31 à extrémité plate 32 ou une tige plate, ou l'extrémité d'un tournevis ou tout autre instrument ou élément convenable dans l'étroite fente existant entre deux feuilles successives 5,6 pour, après un quart de tour, arriver à écarter suffisamment les bords jointifs pour ensuite passer le bec ou la buse de pulvérisation, d'aspersion ou de diffusion 30 d'un appareil de nettoyage et/ou de désinfection.We must also mention, the extraordinary quick and easy assembly of locks locations provided on the structural elements or of external framework but also the simplicity of installation sheet metal sheets. Disassembly or removal are just as simple and fast. To proceed to the dislocation or to loosening of the edges of the sheet metal sheets, just insert an instrument or a tool 31 with a flat end 32 or a flat rod, or the end of a screwdriver or any other instrument or suitable element in the narrow slot between two successive sheets 5,6 for, after a quarter of turn, manage to spread the contiguous edges sufficiently to then pass the spray nozzle or nozzle, spray or diffusion device 30 cleaning and / or disinfection.

Le procédé selon l'invention confère une rapidité exceptionnelle de montage-démontage d'un silo pouvant être exécuté par un personnel non qualifié. Le coût total de la main d'oeuvre pour l'édification et le montage du silo est notablement réduit par le gain en durée et l'utilisation possible d'un personnel non qualifié. The method according to the invention gives a exceptional speed of assembly-disassembly of a silo can be performed by unqualified personnel. The total cost of labor for building and assembly of the silo is significantly reduced by the gain in duration and possible use of non-staff qualified.

Par ailleurs, l'assistance technique au montage peut se limiter à une notice bien détaillée.In addition, technical assistance to mounting may be limited to a very detailed notice.
