Le dispositif décrit est une amélioration, en vue de son industrialisation, du brevet n 99 04 171 qui concerne un dispositif de coffrage perdu-ferrai ! ! aqe-autostabte destiné à la réalisation des murs en béton armé droits ou courbes. The device described is an improvement, with a view to its industrialization, of patent No. 99 04 171 which relates to a lost-iron formwork device! ! aqe-autostabte intended for the realization of straight or curved reinforced concrete walls.
L'adaptation principale est le mode d'assemblage des différents éléments entre eux. The main adaptation is the method of assembling the different elements together.
En effet, la difficulté de réalisation du dispositif du précédent brevet est la soudure des aciers en présence des feuilles de métal déployé galvanisé. Indeed, the difficulty in producing the device of the previous patent is the welding of steels in the presence of sheets of galvanized expanded metal.
L'idée principale est de réaliser une ossature métallique rigide soudée et, par la suite, de fixer les feuilles de métal déployé pliées par des aciers horizontaux traversant les plis des feuilles et coulissant entre des raidisseurs verticaux. The main idea is to make a rigid welded metal frame and, thereafter, to fix the sheets of expanded metal folded by horizontal steels crossing the folds of the sheets and sliding between vertical stiffeners.
Le pliage des feuilles de métal déployé permet un enrobage des aciers de 3 cm. The folding of the sheets of expanded metal allows a coating of the steels of 3 cm.
Les dessins annexés illustrent l'invention dans le cas des murs droits : La figure 1 représente en vue de face la composition du complexe de coffrage-ferraillage. The accompanying drawings illustrate the invention in the case of straight walls: Figure 1 shows a front view of the composition of the formwork-reinforcement complex.
La figure 2 représente en coupe verticale les différents éléments constitutifs. Figure 2 shows in vertical section the different constituent elements.
La figure 3 représente en coupe horizontale les différents éléments constitutifs. Figure 3 shows in horizontal section the different constituent elements.
En référence à ces dessins, le complexe est constitué d'une ossature métallique rigide (1) sur laquelle les feuilles de métal déployé pliées (7) sont fixées par les aciers (6) coulissant entre les raidisseurs (2) de l'ossature (1) et les plis des feuilles de métal déployé (7). With reference to these drawings, the complex consists of a rigid metal frame (1) on which the folded expanded metal sheets (7) are fixed by the steels (6) sliding between the stiffeners (2) of the frame ( 1) and the folds of the sheets of expanded metal (7).
L'ossature rigide (1) est constituée des raidisseurs (2) et des aciers (5) servant à l'écartement des raidisseurs (2) et à la rigidité de l'ossature (1). The rigid frame (1) consists of the stiffeners (2) and the steels (5) serving for the spacing of the stiffeners (2) and for the rigidity of the frame (1).
Les aciers (4) et (6) sont des aciers à haute adhérence pour béton armé et ils constituent le ferraillage du mur. Steels (4) and (6) are steels with high adhesion for reinforced concrete and they constitute the reinforcement of the wall.
Les raidisseurs (2) sont constitués des aciers (3) et (4) soudés entre eux formant des poutres treillis et ils équilibrent les efforts de poussée du béton lors du coulage. The stiffeners (2) consist of steels (3) and (4) welded together forming lattice beams and they balance the thrust forces of the concrete during pouring.
Les feuilles de métal déployé (7) servent de coffrage perdu et de support d'enduit. The expanded metal sheets (7) serve as lost formwork and plaster support.
Les plis des feuilles de métal déployé permettent d'assurer un enrobage régulier des aciers (4) et (6). The folds of the sheets of expanded metal ensure regular coating of the steels (4) and (6).
Dans le cas de murs courbes, les aciers filants (5) et (6) seront cintrés à la forme désirée avant assemblage des autres éléments. In the case of curved walls, the spinning steels (5) and (6) will be bent to the desired shape before assembly of the other elements.
La fixation en pied est assurée par des platines soudées à l'ossature ou bien à l'aide de planches de coffrage clouées sur le sol. Fixing at the foot is ensured by plates welded to the frame or using formwork boards nailed to the ground.
A titre d'exemple, pour une vitesse de bétonnage de l'ordre de 2.5 m/h et pour un mur de 2.5 m de haut, les aciers pourront être : aciers (3) : acier recuit ou FeE24 diamètre 4 mm aciers (4) : acier HA FeE 500 diamètre 6 mm aciers (5) : acier HA FeE 500 diamètre 10 mm aciers (6) : acier HA FeE 500 diamètre 6 mm For example, for a concreting speed of around 2.5 m / h and for a wall 2.5 m high, the steels could be: steels (3): annealed steel or FeE24 diameter 4 mm steels (4 ): HA FeE 500 steel diameter 6 mm steels (5): HA FeE 500 steel diameter 10 mm steels (6): HA FeE 500 steel diameter 6 mm

écartement entre aciers (4) : 20 cm écartement entre aciers (6) : 20 cm écartement entre raidisseurs (2) : 20 cm nombre d'aciers (5) sur la hauteur : 4 de chaque côté feuilles de métal déployé de l'ordre de 1,30 kg/m2 nombre de feuilles par panneaux : 8 unités de 0,60 x 2,50 compte tenu de ces éléments le poids d'un panneau standard de 1,20 long x 2,50 haut serait de l'ordre de 40 kg L'avantage de ce procédé est le suivant : Les panneaux pourraient être assemblés en atelier suivant les dimensions des ouvrages à exécuter. Ils seraient amenés à pied d'oeuvre par camions et il ne resterait qu'à réaliser l'assemblage des ossatures. spacing between steels (4): 20 cm spacing between steels (6): 20 cm spacing between stiffeners (2): 20 cm number of steels (5) on the height: 4 on each side sheets of expanded metal of the order of 1.30 kg / m2 number of sheets per panel: 8 units of 0.60 x 2.50 taking into account these elements the weight of a standard panel of 1.20 long x 2.50 high would be around of 40 kg The advantage of this process is as follows: The panels could be assembled in the workshop according to the dimensions of the works to be executed. They would be brought to work by trucks and it would only be necessary to assemble the frames.
Il pourrait alors être mis en oeuvre par deux personnes sans engin de levage particulier. La mise en oeuvre du béton se ferait alors au camion pompe en une seule intervention lorsque tous les ouvrages seraient coffrés ferraillés. It could then be used by two people without any particular lifting device. The concrete installation would then be done with the pump truck in a single intervention when all the structures were shuttered.
Les enduits de finition seraient exécutés manuellement ou à la machine à projeter avec un enduit monocouche côté extérieur ou un enduit plâtre pour les murs intérieurs.The finishing plasters would be executed manually or in a spraying machine with a monolayer plaster on the exterior side or a plaster plaster for the interior walls.
