La présente invention concerne un procédé constructif de coffraqe perdu -The present invention relates to a constructive process for lost coffraqe -

autostable pour réaliser des murs en béton armé. freestanding to make reinforced concrete walls.
Le coffrage des murs en béton armé est traditionnellement réalisé au moyen de banches en bois ou en métal. Ceci n'est pas bien adapté à la réalisation de petits ouvrages comme les villas et ne permet pas d'être utilisé de façon systématique en The formwork of reinforced concrete walls is traditionally carried out using wooden or metal formwork. This is not well suited to the realization of small works like villas and does not allow to be used systematically in
en remplacemnt des blocs en agglomérés. in replacement of blocks in agglomerates.
Néanmoins la réglementation parasismique oblige l'incorporation de raidisseurs et de chaînages en béton armé en nombre important. Ce qui, dans le cas de murs en However, the seismic regulation requires the incorporation of stiffeners and reinforced concrete chaining in large numbers. Which, in the case of walls in
agglomérés, nécessite des coffrages bois effectués sur place à la demande. agglomerated, requires wooden formwork made on site on request.
Le procédé constructif décrit permet de simplifier l'exécution des murs en béton armé en remplaçant les banches d'une part et le ferraillage d'autre part par un complexe de The construction process described makes it possible to simplify the execution of reinforced concrete walls by replacing the formwork on the one hand and the reinforcement on the other hand by a complex of
coffrage perdu - ferraillage autostable "prêt à couler" manuportable. lost formwork - self-supporting "ready to pour" reinforcement that can be moved.
Les dessins annexés illustrent l'invention: The accompanying drawings illustrate the invention:
La figure 1 représente vue de face la composition du complexe de coffrage-ferraillage. 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 various constituent elements.
La figure 3 représente en coupe horizontale les différents éléments constitutifs. Figure 3 shows in horizontal section the various constituent elements.
La figure 4 représente en coupe horizontale un montant et sa platine de fixation. Figure 4 shows in horizontal section an amount and its mounting plate.
En référence à ces dessins, le complexe est constitué d'une ossature autostable (1) constituée de montants (2) pour le maintien en pied par des chevilles(10), de raidisseurs (3) reliant les deux maillages soudés de fers à béton (4) servant d'armatures pour le béton à mettre en oeuvre et servant aussi de support aux feuilles de métal déployé (5) With reference to these drawings, the complex consists of a freestanding frame (1) consisting of uprights (2) for holding the foot by dowels (10), stiffeners (3) connecting the two welded meshes of concrete irons (4) serving as reinforcements for the concrete to be used and also serving as support for the sheets of expanded metal (5)
utilisé en coffrage perdu et en support d'enduit de parement. used in lost formwork and in support of facing plaster.
Les montants (2) permettent de maintenir la verticalité de l'ossature et d'éviter le The uprights (2) allow to maintain the verticality of the frame and avoid the
soulèvement de l'ossature (1) lors du coulage du béton. lifting of the framework (1) when pouring the concrete.
Les montants (2) sont équipés de platines de fixation métalliques (9) soudées qui The uprights (2) are fitted with welded metal fixing plates (9) which
débordent de l'ossature (1) afin de la fixer sur la dalle basse par des chevilles (10). protrude from the frame (1) in order to fix it on the lower slab by dowels (10).
Les raidisseurs (3) sont constitués de fer à béton (8) formant des poutres treillis qui The stiffeners (3) consist of concrete iron (8) forming lattice beams which
maintiennent les aciers filants (6) par soudure. hold the spinning steels (6) by welding.
Les maillages de fers à béton (4) sont constitués des fers (6) et (7) soudés entre eux The concrete reinforcement meshes (4) consist of the irons (6) and (7) welded together
de manière à constituer l'armature du voile béton armé à réaliser. so as to constitute the reinforcement of the reinforced concrete veil to be produced.
Les maillages (4) servent aussi à transmettre les efforts dus à la poussée du béton frais sur les feuilles (5) jusqu'aux raidisseurs (3) qui équilibrent les efforts excercés par le The meshes (4) also serve to transmit the forces due to the thrust of the fresh concrete on the sheets (5) to the stiffeners (3) which balance the forces exerted by the
béton sur les coffrages opposés réalisés par les feuilles de métal déployé (5). concrete on the opposite forms made by the sheets of expanded metal (5).
A titre d'exemple, pour une vitesse de bétonnage de l'ordre de 2.5 m/h et pour un mur de 2.6 m de haut (hauteur courante), les aciers pourront être: aciers (6): acier HA FeE 500 diamètre 6 mm aciers (7): acier HA FeE 500 diamètre 3 mm aciers (8): acier HA FeE 500 diamètre 4.5 mm -2 - écartement entre aciers(6): 10 cm écartement entre aciers(7): 5 cm écartement entre raidiseurs (3): 20 cm métal déployé en rouleau ou plaques de l'ordre de 1 kg/m2 la face compte tenu de ces éléments le poids d'un panneau standard de 2.10 long x 2.60 haut serait de l'ordre de 80 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 For example, for a concreting speed of the order of 2.5 m / h and for a wall 2.6 m high (running height), the steels could be: steels (6): HA FeE 500 steel, diameter 6 mm steels (7): HA FeE 500 steel diameter 3 mm steels (8): HA FeE 500 steel diameter 4.5 mm -2 - distance between steels (6): 10 cm distance between steels (7): 5 cm distance between stiffeners ( 3): 20 cm expanded metal in roll or plates of the order of 1 kg / m2 the face taking into account these elements the weight of a standard panel of 2.10 long x 2.60 high would be of the order of 80 kg 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 there would be

Il pourrait alors être mis en oeuvre par deux ou trois personnes sans engin de levage particulier. La mise en oeuvre du béton se ferait alors au camion pompe en une seule It could then be used by two or three people without any particular lifting device. The concrete installation would then be done by the pump truck in a single

Nota: Les montants (2) sont soudés aux raidisseurs (3). Note: The uprights (2) are welded to the stiffeners (3).
