Abstract

A method of manufacturing shuttering such as: sheetings and tunnel frameworks, used in building. These shutterings are composed of rectangular or square profile tubes (2, 3, 6, 7) forming a frame intended to receive a slewable and convertible shuttering face (4). The most advantageous applications for this shuttering are a tunnel framework, readily adaptable to the various floor bearing surfaces, and a basis for stabilising sheetings. <IMAGE>

Description

La présente invention concerne un procédé de fabrication et de construction de coffrage outil utile dans le bâtiment et les travaux publics. Il s'applique en général à tous les coffrages et en particulier, à la fabrication d'un outil de coffrage pour le procédé de construction du type coffrage tunnel, permettant rappelons le ici, de coffrer en même temps les murs et les planchers d'une construction.Elle s'applique également pour construire des banches qui servent à coffrer les murs ou tout autre ouvrage d'une construction.The present invention relates to a method of manufacturing and constructing tool formwork useful in building and public works. It applies in general to all formwork and in particular to the manufacture of a formwork tool for the construction process of the tunnel formwork type, allowing it to be recalled here, to form the walls and floors of It is also applicable for constructing formwork which is used to form the walls or any other work of a construction.

Dans les procédés de coffrage tunnel connus, le panneau coffrant vertical est assemblé à 90° avec le panneau coffrant horizontal.Un tel dispositif limite l'emploi du coffrage tunnel à l'exécution d'ouvrage, planchers et murs formant à leur intersection un angle droit.En général les peaux coffantes sont en tale, donc ils sont fabriqués en usine avec des cotes précises formant ainsi des panneaux standards qu'il faut combiner pour construire des ouvrages donnés.Si l'ouvrage comporte des particularités, il est nécessaire de fabriquer des panneaux spéciaux propres à l'ouvrage, panneaux qui ne seront plus employables du fait de leurs dimensions particulières.Les peaux coffrantes en tôle sont fragiles, en cas de détoriation, il est nécessaire de changer le panneau complet.Pour les coffrages tunnels connus à ce jour,-il est obligatoire en cas de transfert d'un chantier à un autre, de démonter et de remonter le coffrage.Il faut également, si les portées du plancher sont différentes, et c'est souvent le cas, changer les panneaux horizontaux.Ces différentes opérations entraînent des frais importants qui ne peuvent être amortis que sur des chantiers conséquents.L'emploi des faces coffrantes en tôle exige que l'ouvrage à construire ne comporte aucune saillie.L'entretien des coffrages métalliques nécessite un personnel qualifié de formation différente que celle des boiseurs qui l'utilisent, d'où des frais de gestion élevés.In known tunnel shuttering methods, the vertical shuttering panel is assembled at 90 ° with the horizontal shuttering panel. Such a device limits the use of tunnel shuttering when carrying out work, floors and walls forming an angle at their intersection. In general, the skins are in the form, so they are manufactured in the factory with precise dimensions, thus forming standard panels which must be combined to build given works. If the work has characteristics, it is necessary to manufacture special panels specific to the structure, panels which will no longer be usable due to their particular dimensions. Sheet metal formwork skins are fragile, in the event of detoriation, it is necessary to change the complete panel. this day, it is compulsory in the event of transfer from one site to another, to dismantle and reassemble the formwork. It is also necessary, if the spans of the floor are different, and it is so If necessary, change the horizontal panels. These different operations entail significant costs which can only be amortized on substantial sites. The use of sheet metal shuttering faces requires that the structure to be built has no protrusions. metal formwork requires qualified personnel with different training than that of the woodworkers who use it, resulting in high management costs.

Le système de coffrage selon l'invention, permet- d'éviter certains de ces inconvénients.Ce coffrage outil du type tunnel conforme à la présente invention peut être transporté d'un chantier à un autre sans être démonté.En effet, la largeur d'encombrement d'une demi coquille au repos est de 1,50 mètre.Le bras articulé permet avec le même outil de coffrer des planchers de différentes portées, en adaptant seulement la face coffrante en contreplaqué et son support situé au-dessus du bras de liaison.The formwork system according to the invention makes it possible to avoid some of these drawbacks. This tunnel-type tool formwork in accordance with the present invention can be transported from one site to another without being dismantled. Indeed, the width d footprint of a half shell at rest is 1.50 meters. The articulated arm allows with the same tool to form floors of different spans, by adapting only the plywood formwork face and its support located above the arm of liaison.

Le principe de coffrage conforme à l'invention est une ossature de contreventement assemblée en elle-même à angle droit, soutenant des supports amovibles de face coffrante.Ce système permet de régler la verticalité et l'horizontabilité des faces coffrantes.Ce principe laisse envisa- ger un emploi plus vaste du matériel et donc, un meilleur amortissement.The formwork principle according to the invention is a bracing frame assembled in itself at a right angle, supporting sup removable ports system coffrante.Ce face to adjust the vertical and horizontabilité coffrantes.Ce principle of sides leaves envisa- g st a wider use of the equipment and therefore, better damping.

Le coffrage outil de l'invention prévoit une peau coffrante en contreplaqué fixé sur une ossature en bois, elle-même fixée sur son support métallique.Cette solution offre plusieurs avantages appréciables.Le bois est le matériau noble du boiseur.Il en connaît les caractéristiques et la mise en oeuvre.En cas de détoriation de la peau coffrante, son utilisateur peut immédiatement faire la réparation, voire même changer la plaque endommagée.Elle permet également de s'adapter à l'ouvrage à construire.The tool formwork of the invention provides a plywood formwork skin fixed on a wooden frame, itself fixed on its metal support. This solution offers several appreciable advantages. Wood is the noble material of the woodworker. He knows its characteristics and the implementation. In the event of detoriation of the formwork skin, its user can immediately make the repair, or even change the damaged plate. It also makes it possible to adapt to the work to be built.

Ce coffrage outil est constitué de tubes structuraux profilés, assemblés entre eux par boulons et écrous.A tout moment, une pièce peut-être changée aisément par son utilisateur.Il est à signaler que ce coffrage démonté est d'un volume réduit, ce qui est appréciable, en particulier pour l'exportation.This tool formwork is made up of profiled structural tubes, assembled together by bolts and nuts. At any time, a part can be easily changed by its user. It should be noted that this disassembled formwork is of reduced volume, which is appreciable, especially for export.

La souplesse de ce syqtème de coffrage tant pour le coffrage tunnel que pour les banches, et en général pour tous les coffrages, contribuera à diminuer le prix de revient d'une construction.The flexibility of this formwork system for both tunnel formwork and formwork, and in general for all formwork, will help to reduce the cost price of a construction.

La figure 1 représente une vue verticale de face d'un demi tunnel droit composé lui-même de plusieurs éléments de charpente supportant un complexe d'habillage.Chaque élément de charpente comprend deux poteaux verticaux de contreventement 6.Un poteau horizontal support de face coffrante 3 est assemblé par un goujon fileté 82 avec les deux poteaux verticaux 2 supports de face coffrante et par un autre goujon fileté 82 avec les 2 poteaux verticaux de contreventement.Une poutre horizontale de liaison 7 est assemblée à angle droit avec les poteaux verticaux de contreventement 6 par l'intermédiaire d'une plaque de renfort 9.FIG. 1 represents a vertical front view of a straight half-tunnel itself composed of several structural elements supporting a cladding complex. Each structural element comprises two vertical bracing posts 6. A horizontal support pole for formwork face 3 is assembled by a threaded stud 82 with the two vertical posts 2 formwork face supports and by another threaded stud 82 with the 2 vertical bracing posts. A horizontal connecting beam 7 is assembled at right angles to the vertical bracing posts 6 by means of a reinforcing plate 9.

La poutre de liaison 7 est assemblée aux poteaux supports verticaux de face coffrante 2 au moyen d'un goujon 82.Le poteau horizontal 3 support de face coffrante reçoit à son extrémité un bras support horizontal de face coffrante 4.Le poteau support horizontal de face coffrante 3 et ce dernier bras 4 sont liés entre eux par un goujon 82.The connecting beam 7 is assembled to the vertical support posts of the formwork face 2 by means of a stud 82.The horizontal post 3 support of the formwork face receives at its end a horizontal support arm of the formwork face 4.The horizontal support post of the face shuttering 3 and this last arm 4 are linked together by a stud 82.

Cet assemblage constitue l'élément de charpente formant la base du coffrage outil destiné à supporter les faces coffrantes.This assembly constitutes the frame element forming the base of the tool formwork intended to support the formwork faces.

Dans un exemple de revendication, les poteaux de contreventement sont formés par des tubes structuraux profilés carrés de 60 X 60 X 3,20 mm.La poutre de liaison horizontale 7 est formée d'un profilé carré de 80 X 80 X 320 mm.Les poteaux support de face coffrante verticaux 2 sont des tubes profilés structuraux de 100 X 80 X 5.Le poteau support horizontal de face coffrante 3 est constitué par un tube profilé rectangulaire de 180 X 80 X 5. Le bras de liaison horizontal est un tube profilé rectangulaire de 180 X 80 X 5.In an example of a claim, the bracing posts are formed by structural square tubes of 60 X 60 X 3.20 mm square. The horizontal connecting beam 7 is formed by a square profile of 80 X 80 X 320 mm. vertical formwork support posts 2 are structural profile tubes of 100 X 80 X 5.The horizontal formwork support post 3 is constituted by a rectangular profile tube of 180 X 80 X 5. The horizontal connecting arm is a profile tube rectangular 180 X 80 X 5.

Des accessoires viennent compléter l'élément de charpente constituant la base du coffrage outil décrit ci-dessus.Pour la manoeuvre du bras de liaison horizontal, il a été conçu soit un système par treuil 15 AVec poulie 17, dont le câble 16 actionne un tube 14 de diamètre 40 X 49 dont la base coulisse sur un guide 13, soit le tube 14 remplacé par un vérin hydraulique à double effet à commande manuelle ou à commande électrique. Le tube 14 peut-être remplacé par un étai métallique tirant ou poussant afin d'affiner le réglage des bras.On a déjà remplacé le treuil 15, 16, 17 par un vérin à double effet qui commande le bras 14.Ca vérin est parallèle au tube 13.Les différents poteaux verticaux supports de face coffrante, sont reliés entre eux, en partie basse par un fer 1 UPN de 100 X 50 X 6 servant de raidisseur bas.En partie haute ils le sont par un fer 12 UPN de 80 X 45 X 6 faisant office de raidisseur haut.Les poteaux de contreventement 6 sont reliés entre eux par des planches de 200 X 40 mm formant ainsi un caisson à outils renforcé par un potelet 8. Sur le raidisseur bas 1 et au pied des poteaux de contreventement 6 sont disposés des boulons 10 de diamètre 26 X 34 faisant office de vérin à vis pour permettre le réglage en altitude et en aplomb de l'ensemble coffrant.Un fer cornière 11 de 150 X 150 X 15 mm de 100 de largeur permet l'assemblage du poteau de support vertical 2 sur le raidisseur bas 1. Le bras de liaison horizontal 4 support de face coffrante, est percé de trous 21 afin de permettre l'assemblage entre les demi tunnels droite et gauche.Ces éléments de charpente une fois montés reçoivent des bois 19 de section 80 X 80 mm de support de face coffrante.Ensuite l'ensemble est habillé par un contreplaqué ou latté plastifié de 15 à 20 mm d'épaisseur 20.Les bois 19 et la peau 20 peuvent être remplacés par une tôle de 3 mm d'épaisseur et des fers omégas en renfort.A l'angle de la peau verticale et de la peau horizontale, la peau verticale s'arrête au nu fini du plancher et le panneau horizontal vient s'arrêter contre 22.Sur le dessus on posera un fer plat filant de 50 X 2 mm laissant un léger défoncé dans le béton.Ce défoncé est facilement rebouchable après décoffrage.Le demi tunnel ainsi formé sera assemblé avec l'autre paroi coffrante de l'autre côté du mur à construire par des tiges filetées 23. Au droit de ces tiges de serrage, on mettra en place sur plaque de renfort 24.11 est à noter que le bras 4 sera habillé jusqu'à son extrémité par les bois 19 et plus 5 cm par la face coffrante 20.Le bras 5 sera habillé depuis l'habillage du bras 4 jusqu'au demi tunnel.Au coffrage on met d'abord le bras 4 en place.Le bras 5 vient s'emboiter sur le 4.Accessories complete the frame element constituting the base of the tool formwork described above. For the operation of the horizontal link arm, it was designed either a winch system 15 With pulley 17, the cable 16 of which actuates a tube 14 with a diameter of 40 X 49, the base of which slides on a guide 13, that is to say the tube 14 replaced by a double-acting hydraulic cylinder with manual control or electric control. The tube 14 can be replaced by a metal stay pulling or pushing in order to refine the adjustment of the arms. We have already replaced the winch 15, 16, 17 by a double-acting cylinder which controls the arm 14. This cylinder is parallel to the tube 13.The various vertical support posts face formwork, are connected together, in the lower part by a 1 UPN iron of 100 X 50 X 6 serving as a low stiffener. In the upper part they are connected by a 12 UPN iron of 80 X 45 X 6 acting as a high stiffener. bracing posts 6 are connected together by planks of 200 X 40 mm thus forming a tool box reinforced by a post 8. On the bottom stiffener 1 and at the foot of the bracing posts 6 are arranged bolts 10 of diameter 26 X 34 acting as a screw jack to allow the height and vertical adjustment of the shuttering assembly. An angle iron 11 of 150 X 150 X 15 mm of 100 width allows the assembly of the vertical support post 2 on the stiffener bottom 1. The horizontal link arm 4 supporting the shuttering face, is pierced with holes 21 in order to allow the assembly between the right and left half tunnels. These frame elements once assembled receive wood 19 of section 80 X 80 mm of formwork face support. Then the whole is ha billed by a plastic-coated plywood or blockboard 15 to 20 mm thick 20. Wood 19 and skin 20 can be replaced by a sheet 3 mm thick and omega irons as reinforcement. vertical and horizontal skin, the vertical skin stops at the finished nude of the floor and the horizontal panel comes to stop against 22. On the top we will put a flat iron wire of 50 X 2 mm leaving a slight smash in the concrete . This knockout is easily reclosable after formwork removal. The half tunnel thus formed will be assembled with the other shuttering wall on the other side of the wall to be constructed by threaded rods 23. reinforcement plate 24.11 should be noted that the arm 4 will be dressed up to its end by the woods 19 and more 5 cm by the shuttering face 20.The arm 5 will be dressed from the dressing of the arm 4 to the half tunnel. In formwork, arm 4 is first put in place. Arm 5 comes to fit on 4.

La figure 2 est une coupe horizontale de dessus de la partie inférieure d'un élément de charpente pour demi tunnel.On remarquera le système d'ossature constitué par les deux poteaux de contreventement 6, les deux poteaux de support vertical 2.0n peut voir ainsi les vérins de réglage 10, les roues pivotantes 48 et en particulier une aile de la cornière égale 11 d'assemblage entre le support vertical 2 et le raidisseur bas 1.Figure 2 is a horizontal section from above of the lower part of a frame element for a half tunnel. Note the framework system constituted by the two bracing posts 6, the two vertical support posts 2.0n can see thus the adjustment jacks 10, the pivoting wheels 48 and in particular a wing of the equal angle 11 of assembly between the vertical support 2 and the bottom stiffener 1.

La figure 3 est une coupe horizontale, vue de dessus du même élément de charpente montrant le principe du treuil.Un tube soudé sur la pièce tenant le bras 14 coulissa de bas en haut ou de bas en haut sur le guide 13.FIG 3 is a horizontal sectional view of the same structural element showing the principle treuil.Un tube welded on the workpiece holding arms 14 slid from bottom to top or from bottom to top on the g u ide 13.

La figure 4 est une coupe horizontale vue de dessous d'un élément de charpente habillée.Figure 4 is a horizontal section seen from below of a dressed structural element.

La figure 5 montre la réunion du bras de liaison horizontale droite 4 et du bras de liaison horizontale gauche 5.FIG. 5 shows the union of the right horizontal link arm 4 and the left horizontal link arm 5.

La figure 6 montre une vue de dessus d'un bras de liaison horizontale droite 4 avec à son extrémité droite le système permettant l'assemblage sur le support horizontal 3.Ce sont deux fers cornières de 180 X 80 X6 soudés sur le bras de liaison 4 et venant de chaque côté de la poutre 3.Figure 6 shows a top view of a straight horizontal link arm 4 with at its right end the system allowing the assembly on the horizontal support 3.These are two angle irons of 180 X 80 X6 welded on the link arm 4 and coming from each side of the beam 3.

Sur la figure 7 sont dessinés deux demi tunnels assemblés en position de coffrage avant bétonnage.On remarquera le mariage des bras de liaison horizontaux droite 4 etgauche 5 avec le trou 21 dans lequel un goujon assurera la maintien des deux bras.Pour fixer les idées, sur le dessin, la portée du plancher est de 4,00 mètres et la hauteur du mur est de 2,50 mètres.Il est à noter que les trous 21 au nombre de deux dans le bras 4 et deux dans le bras 5 ont des diamètres différents par ordre décroissant afin de mettre en place un goujon ayant la forme conique qui assurera la blocage ou le déblocage automatique des deux bras.In Figure 7, two half tunnels are drawn together in the formwork position before concreting. Note the marriage of the right 4 and left 5 horizontal link arms with the hole 21 in which a stud will hold the two arms. To fix the ideas, in the drawing, the span of the floor is 4.00 meters and the height of the wall is 2.50 meters. It should be noted that the holes 21 two in number in arm 4 and two in arm 5 have different diameters in decreasing order in order to set up a stud having the conical shape which will ensure the automatic locking or unlocking of the two arms.

Sur la figure 8 sont représentés par les deux demi tunnels après bétonnage des murs 26 et planchers 25.L'outil est en position de décoffrage.Les bras de liaison horizontaux droite 4 et gauche 5 sont désacouplés.In FIG. 8 are represented by the two half tunnels after concreting of the walls 26 and floors 25. The tool is in the formwork release position. The right horizontal link arms 4 and left 5 are uncoupled.

La figure 9 est une coupe sur le bras de liaison horizontale gauch e 5 formé de deux fers cornières inégaux 180 X 80 X 6 mm.Figure 9 is a section on the left horizontal link arm e 5 formed of two unequal angle irons 180 X 80 X 6 mm.

La figure 10 est une vue de dessous d'un bras de liaison horizontale gauche 5 avec les fers plats liaisonnant par soudure les deux fers cornières.Figure 10 is a bottom view of a left horizontal link arm 5 with the flat bars bonding by welding the two angle irons.

Sur la figure 11 est représenté les mêmes demi tunnels que sur les figures 7 et 8 mais avec des murs inclinés.Les pièces de charpente sont les mêmes, avec seulement déplacement de l'assemblage de la poutre 3 sur le poteau 6 et un seul bras de liaison 5.In Figure 11 is shown the same half tunnels as in Figures 7 and 8 but with inclined walls. The structural parts are the same, with only displacement of the assembly of the beam 3 on the post 6 and a single arm 5.

Sur la figure 12, c'est toujours le même matériel pour exécuter un plancher à double pente avec des murs verticaux.On a cependant ajouté au matériel une rehausse sur les pieds de contreventement 6.Les bois 19 sont entaillés 28 pour permettre le passage des bras de liaison horizontal 4 et 5.Deux trous seront percés afin d'assurer le maintien en position des bras.In figure 12, it is always the same material to execute a double slope floor with vertical walls. However, we added to the material an extension on the bracing feet 6. The woods 19 are notched 28 to allow the passage of the horizontal link arms 4 and 5. Two holes will be drilled to keep the arms in position.

La figure 13 montre le dispositif retenu pour mettre en place une rehausse 27 sur un pied de contreventement 6 par des cornières 27 égales 60 X 60 X 10 mm.Figure 13 shows the device used to set up a riser 27 on a bracing foot 6 by angles 27 equal 60 X 60 X 10 mm.

La figure 14 est une coupe sur une rehausse 27 mise en place sur un pied de contreventement 6.Figure 14 is a section on an extension 27 placed on a bracing foot 6.

Les figures 15 et 16 montrent toujours le même coffrage outil pour exécuter deux murs de hauteur différente avec un plancher avec une seule pente.Pour obtenir ce résultat, on mettra en place une rehausse 29 sur les poteaux de support vertical 2 et une rehausse 27 sur le poteau de contreventement 6.0n remarquera sur la figure XVI la jonction à 90° du poteau de contreventement 6 avec le bras de contreventement horizontal 7.0n notera également l'angle variable entre les poteaux de support vertical 2 et les poutres horizontales 3.Figures 15 and 16 always show the same tool formwork to execute two walls of different height with a floor with a single slope. To obtain this result, we will put in place an extension 29 on the vertical support posts 2 and an extension 27 on the bracing post 6.0n will note in Figure XVI the 90 ° junction of the bracing post 6 with the horizontal bracing arm 7.0n will also note the variable angle between the vertical support posts 2 and the horizontal beams 3.

La figure 17 nous définit la fixation des bois 19 sur les poteaux de support vertical 2.Cette fixation est assurée par un boulon 30 à tête fraisée de 25 mm de longueur et de diamètre 10 mm.FIG. 17 defines the fixing of the woods 19 to the vertical support posts 2. This fixing is ensured by a bolt 30 with a countersunk head 25 mm in length and 10 mm in diameter.

La figure 18 nous montre la fixation du bois 19 sur une poutre de support horizontal 3.C'est un boulon 31 à tête fraisée de 300 mm de longueur et de diamètre 10 mm qui assure le maintien du bois.Figure 18 shows us the fixing of the wood 19 on a horizontal support beam 3. It is a bolt 31 with a countersunk head 300 mm long and 10 mm in diameter which maintains the wood.

La figure 19 nous montre l'assemblage vu de dessus d'un demi tunnel droit et d'une demi coquille gauche, non habillée par la peau coffrante. Portée du plancher 4,00 mètres, longueur des demi coquilles 3,00 mètres. On remarque l'axe 34, de positionnement des éléments de charpente tous les 1,25 mètres.On voit clairement l'assemblage des bras de liaison horizontaux 4 et 5.Figure 19 shows us the assembly seen from above of a right half tunnel and a left half shell, not covered by the formwork skin. Reach from the floor 4.00 meters, length of the half shells 3.00 meters. Note the axis 34, for positioning the structural elements every 1.25 meters. We can clearly see the assembly of the horizontal link arms 4 and 5.

La figure 20 est une vue schématique de dessus des différents types d'assemblages des éléments de charpente entre eux suivant les portées du plancher .Figure 20 is a schematic top view of the different types of assemblies of the frame members together according to the spans of the floor.

En lisant de bas en haut :

  • a) deux poutres 3 = portée minimun 2,80
  • b) deux poutres 3, plus un bras 5 = portée variable de 2,80 à 3,40 m
  • c) deux poutres 3, plus un bras 4 et 5 = portée minimum 3,80 m
  • d) deux poutres 3 plus un bras 4 et 5 = portée variable de 3,80 à 4,30 m
  • e) deux poutres 3 plus un bras 32 et un 33 = portée minimum de 4,80 m
  • f) deux poutres 3 plus un bras 32 et un 33 = portée variable de 4,80 à 6m. Nous rappelons que la poutre 3 est un tube profilé rectangulaire de 180 X 80 X 5 de 1,30 de longueur.Le bras de liaison 4 ou 5 est d'une longueur de 1,00 m.
Reading from bottom to top:
  • a) two beams 3 = minimum span 2.80
  • b) two beams 3, plus one arm 5 = variable span from 2.80 to 3.40 m
  • c) two beams 3, plus one arm 4 and 5 = minimum span 3.80 m
  • d) two beams 3 plus an arm 4 and 5 = variable span from 3.80 to 4.30 m
  • e) two beams 3 plus an arm 32 and a 33 = minimum span of 4.80 m
  • f) two beams 3 plus an arm 32 and a 33 = variable span from 4.80 to 6m. We remind you that beam 3 is a rectangular profile tube 180 X 80 X 5 with a length of 1.30. The connecting arm 4 or 5 is a length of 1.00 m.

Le bras de liaison horizontale droite est constitué par un tube profilé rectangulaire 180 X 80 X 5 de 2,00 m de longueur.The straight horizontal link arm consists of a rectangular profile tube 180 X 80 X 5 with a length of 2.00 m.

Le bras de liaison horizontale gauche 33 est constitué par deux fers cornières de 180 X 80 X 6 de 2,00 m de longueur.The left horizontal link arm 33 is constituted by two angle irons of 180 X 80 X 6 with a length of 2.00 m.

Ces schémas de principe mettent en évidence la souplesse de cet outil de coffrage.On peut en utilisant le même matériel de base, coffrer des planchers de portées variables de 2,80 m à 6,00 m, en changeant simplement les bras de liaison horizontale 4 et 5, ou 32 et 33, et évidemment la peau coffrante disposée sur ces bras.Ce travail peut être exécuté par des boiseurs sans l'aide de spécialistes et avec le minimum de frais.These schematic diagrams highlight the flexibility of this formwork tool. Using the same basic material, we can form floors with variable spans from 2.80 m to 6.00 m, by simply changing the link arms horizontal 4 and 5, or 32 and 33, and obviously the formwork skin placed on these arms. This work can be carried out by woodworkers without the help of specialists and with the minimum cost.

La figure 21 nous montre le même principe de bras adapté sur un cof- frage outil de conception différente de la présente invention constitué par des omégas 36 et un côté en face coffrante 35.0n mettra d'abord en place un fer cornière à ailes inégales 37 de 100 X 80 mm en bout de la peau coffrante.Le bras de liaison horizontale droite 38 est constitué par un tube de 100 X 100 X 3,2.Ce bras est fixé sur la partie coffrante par un support 44 et par un fer plat 39 en renfort soudé sur les omégas. Pour le bras de liaison horizontale gauche 42 constitué par deux fers cornières à ailes égales de 100 X 100 X 12 mm, on retrouve un support 43 soudé sur un fer plat en renfort 39, lui-même soudé sur les omégas 36.Sur ces deux bras, on disposera des bois 41, de 80 mm de largeur par 100 mm de hauteur, sur lesquels on clouera la peau coffrante 40, c'est à dire un contreplaqué de 20mm d'épaisseur.Ce dispositif peut être mis en place quelque soit la disposition des omégas.Les renforts à disposer sur le coffrage existant ne sont pas limitatifs.Figure 21 shows the principle of a suitable arm cof- fra ge different design tool of the present invention consists of omega 36 and a side facing formwork 35.0n will first establish an angle iron unequal wings 37 of 100 X 80 mm at the end of the formwork skin. The straight horizontal link arm 38 is constituted by a tube of 100 X 100 X 3.2. This arm is fixed to the formwork part by a support 44 and by an iron. flat 39 in reinforcement welded on the omegas. For the left horizontal link arm 42 consisting of two angle irons with equal wings of 100 X 100 X 12 mm, there is a support 43 welded on a flat iron as reinforcement 39, itself welded on the omegas 36 . arms, we will have wood 41, 80 mm wide by 100 mm high, on which we will nail the formwork skin 40, that is to say a plywood 20mm thick.This device can be put in place whatever the provision of omegas. The reinforcements to be placed on the existing formwork are not limiting.

La figure 22 est une coupe vue de face des deux bras de liaison horizontale, assemblés entre eux, adaptés sur un principe de coffrage différent de celui de la présente invention.Figure 22 is a sectional front view of the two horizontal link arms, assembled together, adapted on a formwork principle different from that of the present invention.

La figure 23 est une vue de côté du bras de liaison gauche adapté sur un coffrage métallique différent du coffrage de la présente invention.Figure 23 is a side view of the left link arm fitted on a metal formwork different from the formwork of the present invention.

La figure 24 est une vue de côté du bras de liaison horizontal droite adapté sur un coffrage métallique différent du principe de coffrage de la présente invention.Figure 24 is a side view of the right horizontal link arm adapted on a metal formwork different from the formwork principle of the present invention.

La figure 25 est une vue de dessus des supports 43 pour le bras de liaison 42 avec le fer en renfort 39 à souder sur les omégas.FIG. 25 is a top view of the supports 43 for the link arm 42 with the reinforcing iron 39 to be welded on the omegas.

La figure 27 nous montre vu de dessus, le principe de coffrage de la présente invention, avec les deux demi tunnels droit et gauche. Le demi tunnel de droite présente un décrochement dans la partie coffran- te du plancher et un décrochement dans le mur en fond de tunnel. Ces deux demi coquilles sont équipées pour coffrer en plus des murs latéraux, un mur transversal.Figure 27 shows us seen from above, the formwork principle of the present invention, with the two half-tunnels right and left. The half right tunnel has a recess in the floor part coffran- you and a recess in the wall of tunnel bottom. These two half shells are equipped to form in addition to the side walls, a transverse wall.

La figure 28 présente une possibilité de modifier la face coffrante horizontale pour obtenir un motif décoratif en plafond.Le platelage en bois 46 supportera la face coffrante 20.Une pièce en bois 45 complètera l'ensemble.Figure 28 presents a possibility of modifying the horizontal formwork face to obtain a decorative pattern on the ceiling. The wooden decking 46 will support the formwork face 20.A wooden piece 45 will complete the assembly.

La figure 29 représente la même possibilité de modifier la face coffrante mais pour une face coffrante verticale, avec un bois en renfort47o Figure 29 represents the same possibility of modifying the formwork face but for a vertical formwork face, with a reinforcing wood47 o

La figure 30 nous montre la position des roues pivotantes 48 adapté sur un élément de charpente 6 et 2 du coffrage outil.Les roues pivotantes offrent l'avantage de pouvoir déplacer un demi tunnel dans tous les sens, en particulier pour échapper aux trous laissés en réservation dans les planchers.Figure 30 shows us the position of the swivel wheels 48 fitted on a frame element 6 and 2 of the tool formwork. The swivel wheels offer the advantage of being able to move a half tunnel in all directions, in particular to escape the holes left in reservation in the floors.

La figure 31 représente la même banche que la figure 33, mais au repos sur une aire de stockage.La banche est stabilisée par une inclinaison à 60°.Cette stabilisation est rendue possible du fait que le pied 83 est amovible.La mise en place du pied 83, soit en position de stabilisation, soit en position de travail se fait par l'intermédiaire d'un vérin 52 à double effet.Sur les banches connues à ce jour, la stabilisation se fait par la mise en place d'étais ou de lest.Le fer plat 58 boulonné sur les deux poteaux de contreventement 49 limite la course du pied 83.Figure 31 shows the same form as Figure 33, but at rest on a storage area. The form is stabilized by an inclination at 60 °. This stabilization is made possible by the fact that the foot 83 is removable. of the foot 83, either in the stabilization position or in the working position is carried out by means of a double-acting jack 52. On the formwork known to date, the stabilization is carried out by the installation of stays or ballast. The flat iron 58 bolted to the two bracing posts 49 limits the stroke of the foot 83.

La figure 32 représente la même banche que sur la figure 33, mais avec une face coffrante inclinée.Pour obtenir cette performance, on a simplement remplacé la poutre horizontale 49 par la poutre 53.La poutre 53 permet de régler l'inclinaison de la face coffrante.Figure 32 shows the same form as in Figure 33, but with an inclined formwork face. To obtain this performance, the horizontal beam 49 is simply replaced by the beam 53. The beam 53 allows the inclination of the face to be adjusted. shuttering.

La figure 33 nous montre toujours le même principe pour créer un coffrage.Il s'agit ici d'une banche de 2,50 m de hauteur pour coffrer des murs en béton.Nous retrouvons le fer raidisseur 1 au bas, sur lequel viennent s'assembler les poteaux support vertical 2.Ces supports recevront le bois 19 et l'habillage 20.A l'arrière, à 625 mm nous retrouvons deux poteaux de contreventement 49.Ces poteaux sont des tubes structuraux profilés carrés de 80 X 80 X 3,20 mm.Ils sont assemblés à angle droit avec la poutre de contreventement horizontal 50, section 100 X 80 X 5, et la poutre 49 de dimensions 80 X 80 X 3,2 mm.La charpente de cette banche est raidie au pied par le fer UPN 1 et à son sommet par un fer plat 51. Suivant la hauteur de banche, on pourra ajouter d'autres raidisseurs complémentaires.Remarquons les vérins 10, permettant de régler l'altitude et l'aplomb de la banche.Ces banches sont équipées sur toute leur longueur d'un platelage 55, formé par des planches d'échaffaudage de 40 mm d'épaisseur et des planches 54 de 27 mm d'épaisseur formant le garde-corps de protection et raidisseur.La poutre de contreventement 50 est assemblée au poteau 2, par un goujon et au poteau de contreventement 49 par un boulon et écrou et deux fers plats 57 donnant exactement un angle à 90°.Le sommet de la face coffrante est coiffé sur toute sa longueur par un triangle rectangle 56, permettant de mettre en oeuvre le béton plus rapidement.Sur les banches connues à ce jour, le sommet de la ban- che s'arrête de niveau, pour mettre le béton en oeuvre, on doit verser celui-ci entre les faces coffrantes des deux banches.Le système de la présente invention permet un coulage plus rapide du béton puisque les triangles rectangles forment un avaloir au sommet du mur à construire.Figure 33 always shows us the same principle to create a formwork. This is a 2.50 m high form for formwork of concrete walls. We find the stiffening iron 1 at the bottom, on which s '' assemble the vertical support posts 2.These supports will receive the wood 19 and the cladding 20. At the rear, at 625 mm we find two bracing posts 49. These posts are square profiled structural tubes of 80 X 80 X 3 , 20 mm.They are assembled at right angles to the horizontal bracing beam 50, section 100 X 80 X 5, and the beam 49 of dimensions 80 X 80 X 3.2 mm. The frame of this form is stiffened at the foot by the UPN 1 iron and at its top by a flat iron 51. Depending on the height of the formwork, other complementary stiffeners can be added. Note the jacks 10, used to adjust the altitude and the plumb of the formwork. are equipped over their entire length g u eur of a deck 55, formed by scaffolding planks 40 mm thick and planks 54 27 mm thick forming the protective railing and stiffener. The bracing beam 50 is assembled to the post 2, by a stud and to the bracing post 49 by a bolt and nut and two flat irons 57 giving exactly a 90 ° angle. The top of the formwork face is capped over its entire length by a right triangle 56, allowing implement the concrete more rapidement.Sur the wall forms known to date, the top of the Ban-ations stops level to put the concrete into effect, must pay thereof between the formwork faces of the two formwork The system of the present invention allows faster pouring of the concrete since the right triangles form a drain at the top of the wall to be built.

Sur la figure 34 est dessiné l'avaloir placé au sommet d'une banche. Cet avaloir est composé de trois parties réalisées en tôle de 4 mm d'épaisseur environ, filantes sur la longueur de la banche.Pour le montage de cet avaloir, on pose la première partie 62 sur le bois 19.Ensui- te on pose le deuxième élément 63.Ces deux éléments sont fixés par une vis 61 dans le bois 19.Avant de poser le troisième élément 64 on dispose un tasseau filant en bois 65, dans l'élément 63.Ce troisième élément 64 et le deuxième 63 sont fixés ensemble par une vis 61 sur le bois 65.Les trous 59 et 60 sont des trous oblonds.In Figure 34 is drawn the drain placed at the top of a branch. This drain is composed of three parts made of sheet metal of 4 mm thickness, falling along the length of the banche.Pour Mount a g e of this hood, it raises the first portion 62 of the timber 19.Ensui- t e is placed the second two elements 63.Ces member are fixed by a v is 61 in the timber 19.Avant ask the third element 64 is arranged a bracket spinning timber 65, the third element 64 and 63.Ce element the second 63 are fixed together by a screw 61 on the wood 65. The holes 59 and 60 are oblong holes.

La figure 35 est une vue en élévation d'une banche, côté pied de contreventement vertical 49.On reconnaît les planches 54 formant le garde-corps sur la passerelle de travail.Le fer plat 58 limiteur de course du pied stabilisateur 83 est fixé par boulons sur les deux poteaux de con- treventemebt 49.Remarquons le goujon 66 permettant la manoeuvre du pied stabilisateur 83.Figure 35 is an elevational view of a panel, vertical bracing foot side 49. We recognize the boards 54 forming the railing on the working bridge. The flat iron 58 stroke limiter of the stabilizing foot 83 is fixed by bolts on both con- t poles r eventemebt 49.Remarquons the stud 66 to enable the operation of the stabilizer 83 foot.

La figure 36 est une vue en élévation de la face intérieure d'une banche, mettant en valeur un principe de charpente.On remarquera la face coffrante 20 clouée.sur les bois de support 19.La poutre de contre- ventement 50 est placée entre les deux poteaux 2 et les deux poteaux 49, tandisque la poutre 49 est placée entre les deux poteaux 2 et se fixe sur le c8té intérieur des poteaux de contreventement 49, par un fer plat soudé à son extrémité, laissant ainsi un vide pour le pied stabilisateur 83 lorsque la banche est verticale.Figure 36 is an elevational view of the inner side of a formwork, highlighting a block charpente.On notice the front shuttering 20 clouée.sur the supporting wood 19.La beam cross ve ntly 50 is placed between the two posts 2 and the two posts 49, t a ndisque the beam 49 is placed between the two posts 2 and is fixed on the inner side of the bracing posts 49, by a flat iron welded at its end, thus leaving a vacuum for the stabilizing foot 83 when the form is vertical.

La figure 37 nous montre une vue de dessus, en coupe, du principe d'assemblage de deux coffrages banche ou coffrage tunnel.Nous avons à chaque extrémité d'un coffrage, un fer plat 67 allant de bas en haut sur toute la longueur.Entre ce fer plat 67 et le poteau support vertical 2, on mettra en place un tube carré de 100 X 100 X 3,2 mm servant de renfort du fer 67.Entre ce poteau de jonction 68 et la face coffrante 20, on mettra un bois de 80 X 80, 69 servantégalement de renfort.Les deux banches seront liaisonnées entre elles par un boulon et écrou mis en place dans les trous 70 prévus à cet effet.Il est à remarquer sur le dessin que les fers plats, sur le dessin du bas passent dans la face coffrante, alors que sur le dessin du haut, ils s'arrêtent contre la face coffrante.Figure 37 shows a top view, in section, of the principle of assembling two formwork formwork or tunnel formwork. We have at each end of a formwork, a flat iron 67 going from bottom to top on the entire length. Between this flat iron 67 and the vertical support post 2, we will put in place a square tube of 100 X 100 X 3.2 mm serving as reinforcement for the iron 67. Between this junction post 68 and the formwork face 20 , we will put a wood of 80 X 80, 69 also serving as reinforcement. The two forms will be linked together by a bolt and nut put in place in the holes 70 provided for this purpose. It should be noted in the drawing that the flat irons , in the bottom drawing pass into the form face, while in the top drawing, they stop against the form face.

La figure 38 est une vue en élévation d'un côté d'une banche.On remarquera les trous 70, permettant par boulonnage d'assembler deux banches entre elles.Le repère 71 est un guide d'assemblage.Figure 38 is an elevational view of one side of a panel. Note the holes 70, allowing bolting to assemble two forms between them. The reference 71 is an assembly guide.

Sur la figure 39 est dessiné un guide d'assemblage, à gauche la partie femelle 72, à droite la partie mâle 73.Ces deux pièces sont usinées. La pièce mâle 73 est un cône à tête arrondie, fixé sur la tôle 47 et 58 par un boulon.L'intérieur de la pièce femelle 72, épouse le volume du cône 73.Elle n'est pas fermée à son extrémité gauche, laissant un trou. La base 84 de cette pièce est carrée.L'espace libre à chaque angle du carré permet la fixation de la pièce sur les fers 67 et 68.Ce dispositif facilite l'assemblage de deux banches par auto guidage.In FIG. 39 is drawn an assembly guide, on the left the female part 72, on the right the male part 73. These two parts are machined. The male part 73 is a cone with a rounded head, fixed to the sheet metal 47 and 58 by a bolt. The interior of the female part 72 follows the volume of the cone 73. It is not closed at its left end, leaving a hole. The base 84 of this part is square. The free space at each corner of the square allows the part to be fixed on the irons 67 and 68. This device facilitates the assembly of two forms by self-guiding.

Sur la figure 40 sont dessinées les différentes possibilités de coffrage avec le matériel de la présente invention.Les coffrages repérés 74 à 77, sont des éléments standards de 2,50 m de hauteur et largeur dans l'ordre croissant desdits repères : 1,25 m, 1,50m , 2,50 m et 5 mètres. Liste non limitative.Ces banches trouveront principalement leur emploi dans le bâtiment.La hanche 78 est de 5,00 m ou 6,00 m de hauteur, avec les mêmes cotes de largeur que les précédentes dessinées.Ces coffrages 78 seront principalement employés dans les Travaux Publics.Avec le principe de fabrication de coffrage de la présente invention, on peut réaliser des coffrages avec le sommet incliné 79 et 80.Il est à noter que le matériel ayant servi à fabriquer une deces banches est récupérable après usage, pour construire d'autres coffrages.C'est une économie importante que les coffrages actuellement connus ne permettent pas.In FIG. 40 are shown the different possibilities of formwork with the material of the present invention. The formworks marked 74 to 77, are standard elements 2.50 m high and wide in ascending order of said references: 1.25 m, 1.50m, 2.50m and 5m. Nonlimiting list.These forms will mainly find their use in the building.The hip 78 is 5.00 m or 6.00 m in height, with the same width dimensions as the previous drawings.These 78 forms will be mainly used in Public works. With the formwork manufacturing principle of the present invention, we can make formwork with the inclined top 79 and 80. It should be noted that the material used to make these forms is recoverable after use, to build 'other formwork. This is a significant saving that currently known formwork does not allow.

La figure 41 est une coupe sur un coffrage des voiles extérieurs. Les poteaux de support vertical 2 sont doublés par un poteau 81, constitué d'un tube profilé rectangulaire 100 X 80 X 5.Ce système permet d'ex- acuter des ouvrages décoratifs en béton, au sommet d'un mur, en même temps que l'on coule ledit mur.Dans les coffrages de banches connues à ce jour, il faut exécuter premièrement le mur, deuxièmement l'élément décoratif.Pour fixer les idées, la figure 41 représente un coffrage permettant d'exécuter un mur, avec en saillie, une corniche.Il est à noter que le même matériel permet également de coffrer un mur droit sur toute sa hauteur, en modifiant seulement la peau coffrante.Figure 41 is a section on a formwork of the outer walls. The vertical support posts 2 are lined with a post 81, made up of a rectangular profiled tube 100 X 80 X 5. This system makes it possible to execute decorative concrete works, at the top of a wall, at the same time that the said wall is poured. In the formwork formwork known to date, it is necessary to first execute the wall, secondly the element d écoratif.Pour fix ideas, Figure 41 shows a formwork for performing a wall with projecting a corniche.Il be noted that the same equipment also allows for shuttering a right wall over its entire height by altering only the shuttering skin.

La figure 42 représente le coffrage d'un muret avec une partie saillante par exemple, garde-corps avec en partie supérieure une jardinière ou en acrotère.Ce dessin montre principalement la souplesse du système de coffrage décrit ci-avant.Les poteaux et les poutres composant la charpente pour coffrage, conformément à la présente invention, permettent de réaliser une multitude de types de coffrages.Ce matériel étant récupérable, transformable à volonté, apporte à ces utilisateurs du Bâtiment ou des Travaux Publics, une rentabilité certaine du matériel.En particulier, le coffrage du type tunnel du fait desa mobilité et de sa propriété de pouvoir s'adapter rapidement à différentes portées de planchers, apportera un gain de temps, également une importante économie dans le prix de revient des ouvrages de Bâtiment ou de Travaux Publics.Figure 42 represents the formwork of a low wall with a projecting part for example, railing with in the upper part a planter or in parapet. This drawing mainly shows the flexibility of the formwork system described above. The posts and the beams composing the framework for formwork, in accordance with the present invention, make it possible to produce a multitude of types of formwork. This material being recoverable, transformable at will, provides these users of Building or Public Works, a certain profitability of the material. , tunnel type formwork due to its mobility and its property of being able to adapt quickly to different spans of floors, will save time, also a significant saving in the cost price of construction or public works.
