Description
Actuellement les réservoirs, silos, tours, ouvrages similaires, sont réalisés traditionnellement en coffrage bois ou métallique en coffrage bois ou métallique, ce qui est long et onéreux et problématiques du fait que l'on ne trouve de moins en moins de main d'oeuvre qualifiée tels que ferrailleurs et coffreurs. Currently tanks, silos, towers, similar works, are traditionally made in wood or metal formwork in wood or metal formwork, which is long and expensive and problematic because we find less and less labor qualified such as scrap dealers and formworkers.
II existe bien un procédé de préfabrication de réservoirs, silos, tours, ouvrages similaires Brevet FR 2685931 qui consiste à édifier les dits ouvrages, dont les réservoirs cylindriques couverts par coupole (2) et ceinture (3) encastrées sur la partie haute de la parois de la cuve à l'aide d'éléments préfabriqués juxtaposés (1i) et ou superposés (1s) s'assemblant par boulonnage pour la cuve et la coupole mais la ceinture (3) et le dôme supérieur (4) sont coffrés, ferraillés et coulés en place, opération se revtant complexe et fort onéreuse et demandant beaucoup de main d'oeuvre spécialisée (coffreur et ferrailleur) et de plus du fait que les nouvelles recommandations professionnelles prévoient la coupole (2) et les parois de la cuve (1) indépendantes c'est-à-dire que la coupole ceinture doit pouvoir se déplacer indépendamment de la paroi de la cuve ce qui a pour effet de rendre le procédé précité caduque. There is indeed a process for the prefabrication of tanks, silos, towers, similar works Patent FR 2685931 which consists of building said works, including cylindrical tanks covered by cupola (2) and belt (3) embedded on the upper part of the walls of the tank using juxtaposed (1i) and or superimposed (1s) prefabricated elements which are bolted together for the tank and the dome but the belt (3) and the upper dome (4) are shuttered, reinforced and cast in place, operation being complex and very expensive and requiring a lot of specialized labor (formwork and scrap metal) and moreover the fact that the new professional recommendations provide for the dome (2) and the walls of the tank (1) independent, that is to say that the belt dome must be able to move independently of the wall of the tank, which has the effect of rendering the aforementioned process obsolete.
Le but de l'invention est donc de présenter un procédé permettant de construire selon les règles de l'art, très économiquement et dans des délais très courts et pallier le manque crucial de main-d'oeuvre spécialisée telle que l'emploi de coffreurs et ferrailleurs par préfabrication intégrale c'est-à-dire en intégrant la ceinture (3) de la coupole dans les secteurs de coupole (2) et en préfabricant la calotte sphérique (4) afin de faire reposer ces secteurs sur son becquet (31) en partie haute, 1'ensemble prenant appui sur la tour échafaudage (5) la partie basse de ces secteurs reposant sur la partie haute des parois de la cuve (1) et le montage de ces éléments se faisant suivant la méthode opératoire suivante :
. Après terrassements coulage du béton de propreté (a) qui doit présenter une planéité sans défaut.The object of the invention is therefore to present a process making it possible to build according to the rules of the art, very economically and in a very short time and to compensate for the crucial lack of specialized labor such as the use of formworkers and scrap dealers by integral prefabrication, that is to say by integrating the belt (3) of the dome in the dome sectors (2) and by prefabricating the spherical cap (4) in order to rest these sectors on its spoiler (31 ) in the upper part, the assembly bearing on the scaffolding tower (5), the lower part of these sectors resting on the upper part of the walls of the tank (1) and the mounting of these elements using the following operating method:
. After earthworks pour clean concrete (a) which must have a flawless flatness.
Mise en place à la grue des composants de parois 1s, 1i réglés et maintenus en position par des étais tirants-poussants télescopiques. Placement of wall components 1s, 1i adjusted with the crane and held in position by telescopic struts.
Coulage à l'aide d'une matière béton ou autre des vides (8) verticaux et éventuellement selon la hauteur du réservoir des vides (8) horizontaux. Pouring using a concrete material or other vertical voids (8) and possibly depending on the height of the tank of horizontal voids (8).
Ferraillage et coulage du fond de cuve (6)
Montage de l'échafaudage central intérieur (5) de soutien.Reinforcement and casting of the tank bottom (6)
Installation of the internal central scaffolding (5) for support.
'Mise en place à la grue de la calotte (4) des secteurs (2) coulage des joints de ceinture (3), secteurs (2) et calotte (4). 'Crane (4) installation of sectors (2) pouring of belt seals (3), sectors (2) and cap (4).
'montage de la tour échafaudage (5) après durcissement du béton et enlèvement. 'erection of the scaffolding tower (5) after hardening of the concrete and removal.
Mise éventuelle des composants en état de précontrainte par traction des câbles prévus à cet effet dans les gaines (7). Possible placing of the components in a prestressed state by pulling the cables provided for this purpose in the sheaths (7).
'Mise en eau de l'ouvrage et épreuve hydraulique. 'Water filling of the structure and hydraulic test.
A noter qu'il peut tre placé dans les joints becquets-béton pour parfaire l'étanchéité du vide (8) à la laitance du béton des joints faible diamètre en PVC ou aire (17)
L'invention apportant ainsi un gain de temps d'exécution important et une économie substantielle.Note that it can be placed in the spoiler-concrete joints to perfect the tightness of the vacuum (8) to the milt of the concrete of the small diameter PVC joints or area (17)
The invention thus bringing a significant saving in execution time and a substantial saving.

be thicker in the joint area than in the so-called parts
current
The spoilers on the outside of the components (li), HsL. juxtaposed
may include a hatch (48) intended to flow the material
in order to reduce the fall height of the latter in a vacuum (8)
In the case where the elements are planar they assemble at an angle, when it is a question of building a polygonal wall, the self-spoiler formwork is of unequal length or the formwork (12)
died either in deformable or rigid matter and in two
three rotating parts on one or two hinges "as shown
in Figures 4k, 41 4i 4j which are horizontal sections of the vertical joints between Danneaux.

-L'assemblage des éléments juxtaposés de secteur de coupole (2) se fait selon les secteurs de la mme manière que précédemment ; à noter que dans ce cas les joints de becquets supérieurs sont supprimés ; quant à la ceinture intégrée (5) son assemblage se fait comme pour les composants de la paroi (1), l'extrémité des secteurs (2) reposant sur la calotte (4) sur les becquets (32) qu'elle comporte.-The assembly of the juxtaposed elements of the dome sector (2) is done according to the sectors in the same manner as previously; note that in this case the upper spoiler seals are removed; as for the integrated belt (5) its assembly is done as for the components of the wall (1), the end of the sectors (2) resting on the cap (4) on the spoilers (32) which it comprises.
-Le béton d'assemblage des éléments superposés peut également tre mis en place depuis les orifices (32) ; il est possible de supprimer les becquets (27) des éléments inférieurs en prévoyant de loin en loin des armatures (20) de section adéquate pour maintenir l'élément supérieur en équilibre sur l'élément inférieur et à coffrer le vide 8) côté parements par des coffrages comportant des orifices (32) pour couler ou injecter le béton. Des plots (19) émergeant d'un élément peuvent tre prévus.The assembly concrete of the superimposed elements can also be placed from the orifices (32); it is possible to remove the spoilers (27) of the lower elements by providing, from time to time, reinforcements (20) of adequate section to keep the upper element in balance on the lower element and to form the vacuum 8) on the facing side by forms having holes (32) for pouring or injecting concrete. Studs (19) emerging from an element can be provided.
-Des parois verticales préfabriquées en forme d'arc de cercle dont les courbures internes et externes peuvent tre égales ou différentes sont telles que les chants des éléments pourvus de becquets (13) tantôt internes (13) tantôt externes (14) se juxtaposent en créant un vide (8) dans lequel viennent se croiser les armatures des chants des dits éléments (1) et qui reçoit le béton de clavage dont l'épaisseur est sensiblement égale à celle de la paroi.-Prefabricated vertical walls in the shape of an arc of a circle whose internal and external curvatures can be equal or different are such that the edges of the elements provided with spoilers (13) sometimes internal (13) sometimes external (14) are juxtaposed creating a void (8) in which the reinforcements of the edges of the said elements (1) intersect and which receives the concrete of keying whose thickness is substantially equal to that of the wall.
-Au lieu d'intégrer la ceinture (3) il est intégré que son coffrage perdu aux différents secteurs pour alléger les composants secteurs-ceinture.-Instead of integrating the belt (3) it is integrated that its formwork lost to the different sectors to lighten the sector-belt components.
-Dans le cas de coupole dont la flèche est très faible ou voire nulle, la calotte sphérique (4) dans ce cas est posée sur un poteau fixe dont la partie inférieure fait corps avec le fond de cuve (6).-In the case of a dome whose deflection is very weak or even zero, the spherical cap (4) in this case is placed on a fixed post whose lower part is integral with the tank bottom (6).
-les composants de paroi en contacts avec la base (0) soit à leur base comportent une amorce de fond de cuve (70) avec des aciers en attentes (42) ou sans amorce mais avec toutefois des aciers en attentes.the wall components in contact with the base (0), either at their base, include a tank bottom primer (70) with waiting steel (42) or without primer but with waiting steel, however.
-Les becquets internes ou externes des éléments de paroi sont supprimés et remplacés par des becquets amovibles en béton armé ou autre.-The internal or external spoilers of the wall elements are eliminated and replaced by removable spoilers in reinforced concrete or other.
