Description

"Système constructif utilisant des coffrages perdus""Constructive system using lost formwork"

Dans le domaine du bâtiment et des travaux publics, il est connu d'utiliser des coffrages perdus délimitant un volume dans lequel est coulé le béton constitutif d'un mur. Il est connu aussi de réaliser ces coffrages en matériau isolant, afin que le mur finalement obtenu présente des caractéristiques isolantes.In the field of building and public works, it is known to use lost formwork delimiting a volume in which the concrete constituting a wall is poured. It is also known to produce these forms in insulating material, so that the wall finally obtained has insulating characteristics.

Ces coffrages perdus peuvent être divisés en deux catégories : ceux constitués par des éléments plans et ceux constitués par des blocs creux parallélépipèdiques.These lost forms can be divided into two categories: those made up of planar elements and those made up of hollow rectangular blocks.

Ceux du premier type n'ont pas une grande plage d'utilisation, car leurs dimensions déterminent celles de la construction leur utilisation est en outre complexe, car elle nécessite l'emploi d'étriers de liaison difficiles à mettre en place ; et ils ne permettent pas une isolation suffisante, notamment aux extrémités des murs.Those of the first type do not have a wide range of use, since their dimensions determine those of the construction, their use is also complex, because it requires the use of connection stirrups which are difficult to install; and they do not allow sufficient insulation, especially at the ends of the walls.

Ceux du deuxième type qui n'obligent qu'à superposer des blocs de coffrage parallélépipèdiques en les décalant d'une rangée à l'autre sont d'une utilisation plus simple ; ces blocs s'adaptent à des plans architecturaux variés. Ils présentent toutefois quelques graves inconvénients, à savoir notamment :

  • - Le mur banché comporte des liaisons en matière isolante qui, en cas de feu, fondent et laissent apparaître, dans le mur en béton, des "conduits" horizontaux de fort diamètre qui risquent de provoquer des appels d'air et ainsi transmettre le feu entre les parois ;
  • - Les angles sont affaiblis par le fait qu'au niveau de chaque rangée de blocs il y a discontinuité dans le plan horizontal entre le béton constituant un mur et. le béton constituant le mur adjacent, la continuité n'étant respectée que dans le plan vertical ;
  • - Le volume des blocs rend le prix de leur transport prohibitif, car le rapport volume/poids est élevé. Le rayon d'utilisation par rapport au lieu de production est donc nécessairement réduit.
Those of the second type which only require superimposing parallelepipedal formwork blocks by shifting them from one row to another are easier to use; these blocks adapt to various architectural plans. However, they have some serious drawbacks, namely:
  • - The shuttered wall has connections made of insulating material which, in the event of fire, melts and lets appear, in the concrete wall, horizontal "ducts" of large diameter which are likely to cause air calls and thus transmit the fire. between the walls;
  • - The angles are weakened by the fact that at the level of each row of blocks there is discontinuity in the horizontal plane between the concrete constituting a wall and. the concrete constituting the adjacent wall, continuity being respected only in the vertical plane;
  • - The volume of the blocks makes the price of their transport prohibitive, because the volume / weight ratio is high. The radius of use in relation to the place of production is therefore necessarily reduced.

L'invention vise à conserver les avantages de ces deux types de coffrages, mais à en supprimer les inconvénients. Elle a pour objet un système constructif constitué en combinaison par des plaques jouant le rôle de banches, par des échelles horizontales déterminant l'écartement de ces plaques et dont les unes positionnent les plaques sur le sol et les autres positionnent les plaques les unes sur les autres, et par des échelles verticales servant d'éléments raidisseurs entre les plaques.The invention aims to retain the advantages of these two types of formwork, but to eliminate the drawbacks. It relates to a constructive system constituted in combination by plates playing the role of formwork, by horizontal scales determining the spacing of these plates and some of which position the plates on the ground and the others position the plates one on the others, and by vertical scales serving as stiffening elements between the plates.

Les plaques de coffrage (1) constituées en matière isolante sont réalisées en matériau de résistance appropriée à la nature de la matière coulée. Ce matériau de préférence de haute densité peut être par exemple du polystyrène expansé, de la mousse de polystyrène extrudée, de la mousse de polyuréthane, ou formo-phénolique...The formwork plates (1) made of insulating material are made of material of resistance appropriate to the nature of the material being cast. This preferably high-density material may for example be expanded polystyrene, extruded polystyrene foam, polyurethane foam, or formo-phenolic ...

Dans la masse de la plaque (1) peut être prévue une armature (2) constituée par une âme résistante. Cette âme peut être réalisée par augmentation de la densité moléculaire du matériau isolant, ou par interposition d'une feuille pleine ou a claire voie, par exemple : panneau de contre plaqué ou de bois compressé, fibre de verre, grillage, treillis soudé, tissu synthétique... De cette armature (2) sont solidaires des tubes (3) qui font corps avec la plaque (1) et débouchent sur ses faces supérieure et inférieure. Ces tubes peuvent être constitués en n'importe quelle matière : métal, matière plastique, fibre de verre... sous réserve de présenter une rigidité suffisante pour permettre la liaison des plaques par les organes prévus dans ce but.In the mass of the plate (1) can be provided a frame (2) constituted by a resistant core. This core can be produced by increasing the molecular density of the insulating material, or by interposing a solid sheet or a clear track, for example: plywood or compressed wood panel, fiberglass, mesh, welded mesh, fabric synthetic ... From this frame (2) are integral tubes (3) which are integral with the plate (1) and open on its upper and lower faces. These tubes can be made of any material: metal, plastic, fiberglass ... provided that they have sufficient rigidity to allow the plates to be connected by the means provided for this purpose.

Ces organes sont constitués par des échelles horizontales (4) formées de deux longerons (5) et de traverses (6) ; les longerons (5) portent des doigts (7) coopérant avec les tubes (3) des plaques (1). Ces échelles déterminent l'écartement des plaques (1). Celles de base sont posées et fixées sur le sol ; les autres sont placées sur le bord supérieur de chaque rangée de plaques, et servent au positionnement de la rangée supérieure.These members consist of horizontal ladders (4) formed by two side members (5) and crosspieces (6); the side members (5) carry fingers (7) cooperating with the tubes (3) of the plates (1). These scales determine the spacing of the plates (1). Those of base are posed and fixed on the ground; the others are placed on the upper edge of each row of plates, and are used for positioning the upper row.

Chaque plaque (1) comporte, en outre, sur sa face intérieure, des rainures verticales (8) parallèles entre elles et régulièrement réparties. Elles sont destinées à servir de logements les unes ou les autres :

  • - soit à des plaques d'extrémité (9) permettant la fermeture latérale du coffrage délimité par les plaques (1),
  • - soit à des échelles verticales (10) constituées par des longerons (11) pénétrant dans les rainures (8) et par des traverses (12). Les traverses (12) présentent des encoches (12a) qui, débouchant dans leur face supérieure. sont destinées au positionnement des éléments d'armature métallique (12b) du béton. à une distance constante des plaques de coffrage, comme montré à la figure 1. Ces échelles dont la hauteur peut être quelconque s'étendent sur plusieurs rangées de plaques et jouent le rôle d'éléments raidisseurs pour le coffrage. Ces échelles verticales (10) peuvent en fait, comme le montre la figure 2, être utilisées en échelles horizontales entre deux rangées de plaques (1).
Each plate (1) further comprises, on its inner face, vertical grooves (8) parallel to each other and regularly distributed. They are intended to serve as accommodation one or the other:
  • - either to end plates (9) allowing the lateral closure of the formwork delimited by the plates (1),
  • - Either on vertical scales (10) constituted by longitudinal members (11) penetrating into the grooves (8) and by crosspieces (12). The crosspieces (12) have notches (12a) which, opening in their upper face. are intended for positioning the metal reinforcement elements (12b) of the concrete. at a constant distance from formwork plates, as shown in Figure 1. These ladders, the height of which can be arbitrary, extend over several rows of plates and act as stiffening elements for the formwork. These vertical scales (10) can in fact, as shown in Figure 2, be used in horizontal scales between two rows of plates (1).

D'autres accessoires sont prévus, notamment pour la liaison des plaques (1) dans les angles du coffrage. Il s'agit d'équerres (13) dont les deux branches comportent des doigts (14) pénétrant dans les tubes raidisseurs (3) de ces plaques.Other accessories are provided, in particular for connecting the plates (1) in the corners of the formwork. These are brackets (13), the two branches of which have fingers (14) penetrating into the stiffening tubes (3) of these plates.

Comme cela a été ci-dessus décrit en référence aux figures 1 à 7, le coffrage nécessite pour son montage et son utilisation l'emploi de diverses échelles ayant des rôles spécifiques. Dans le cas de la variante d'exécution représentée aux figures 8 à 21, une forme particulière est donnée aux échelles. Les unes (15) - figure 10 - servent d'écarteurs de base, et les autres (16) - figures 8 et 9 - servent d'éléments de rigidification.As has been described above with reference to Figures 1 to 7, the formwork requires for its assembly and use the use of various scales having specific roles. In the case of the alternative embodiment shown in Figures 8 to 21, a particular form is given to the scales. Some (15) - Figure 10 - serve as basic spacers, and others (16) - Figures 8 and 9 - serve as stiffening elements.

Les écarteurs de base (15) sont constitués par deux longerons (17) et par deux traverses (18). Les longerons (17) ont une section en forme d'équerre grâce à laquelle, par leur aile horizontale (17a), ils peuvent être fixés sur la dalle servant de sol et, par leur aile verticale (17b). ils pénètrent dans des rainures longitudinales aménagées dans la face inférieure des plaques (I). Quant aux traverses (18) de chaque élément de base (15) elles présentent chacune deux zones (19) décrochées vers le haut, et ce à proximité de leurs deux extrémités.The base spacers (15) consist of two side members (17) and two cross members (18). The longitudinal members (17) have a cross-section in shape with which, by their horizontal wing (17a), they can be fixed to the slab serving as the floor and, by their vertical wing (17b). they penetrate into longitudinal grooves arranged in the underside of the plates (I). As for the crosspieces (18) of each base element (15), they each have two zones (19) which are hooked upwards, and this near their two ends.

Chaque traverse (18) présente en outre des parties (I8a) faisant saillie de son bord supérieur, au nombre de deux dans la forme d'exécution représentée au dessin. Dans chaque partie (18a) est ménagée une encoche (18b) destinée au logement d'un élément d'armature métallique. Cette encoche est asymétrique et limitée latéralement par un bord sensiblement vertical du côté le plus proche d'une plaque et de son autre côté par un bord incliné permettant quel que soit le diamètre des éléments d'armature, leur positionnement à distance constante des plaques de coffrage.Each crosspiece (18) further has parts (I8a) projecting from its upper edge, two in number in the embodiment shown in the drawing. In each part (18a) is provided a notch (18b) for housing a metal frame member. This notch is asymmetrical and limited laterally by a substantially vertical edge on the side closest to a plate and on the other side by an inclined edge allowing whatever the diameter of the reinforcing elements, their positioning at constant distance from the plates. formwork.

Pour les autres échelles (16), chacune est constituée par deux cadres désignés de façon générale, respectivement par (20) et par (21). Chacun est formé par deux longerons et par deux traverses. Pour le cadre (20), les longerons sont désignés par (22) et les traverses sont désignées par (23) ; et pour le cadre (21) les longerons sont désignés par (24) et les traverses par (25). Ces deux cadres (20) et (21) présentent la particularité d'être articulés l'un à l'autre au niveau d'une traverse (23) de l'un et d'une traverse (25) de l'autre.For the other scales (16), each consists of two frames generally designated, respectively (20) and (21). Each is formed by two beams and two crosspieces. For the frame (20), the side members are designated by (22) and the cross members are designated by (23); and for the frame (21) the side members are designated by (24) and the cross members by (25). These two frames (20) and (21) have the particularity of being articulated to each other at the level of a crosspiece (23) of one and of a crosspiece (25) of the other.

Chaque traverse (23) présente des parties en saillie (23a) dans lesquelles sont ménagées des encoches (23b) correspondant aux parties en saillie et encoches'(18a) et (18b) des éléments de base (15).Each crosspiece (23) has projecting parts (23a) in which are provided notches (23b) corresponding to the projecting parts and notches' (18a) and (18b) of the basic elements (15).

Cette articulation peut être réalisée de façon quelconque. Quel que soit son agencement, elle permet au cadre (21) dont la largeur est inférieure à celle du cadre (20) d'être inclus dans le cadre (20) comme le montre la figure 8, ou d'occuper une position perpendiculaire à lui comme le montre la figure 9. La première position est celle de repos, c'est-à-dire de stockage ou de transport ; la seconde position est celle d'utilisation. Dans cette position, la traverse (25) du cadre (21) vient, en même temps qu'elle s'accroche à la traverse (18,23) d'un cadre (15,20) situé en-dessous, verrouiller les armatures métalliques (23c) positionnées dans les encoches (18b.23b) des traverses (18,23).This articulation can be carried out in any way. Whatever its arrangement, it allows the frame (21) whose width is less than that of the frame (20) to be included in the frame (20) as shown in Figure 8, or to occupy a position perpendicular to him as shown in Figure 9. The first position is that of rest, that is to say, storage or transport; the second position is that of use. In this position, the crosspiece (25) of the frame (21) comes, at the same time as it hooks to the crosspiece (18,23) of a frame (15,20) located below, lock the frames metal (23c) positioned in the notches (18b.23b) of the sleepers (18,23).

Les longerons (22) du cadre (20) qui est utilisé en position horizontale ont une section, par exemple en T couché. afin de se loger par leur aile horizontale (22a) dans une zone en retrait (26) de la face inférieure des plaques (1) et de pénétrer par leur aile supérieure (22b) et inférieure (22c) dans des rainures (27) aménagées dans les faces inférieure et supérieure des plaques (1). Pour qu'une bonne liaison soit réalisée entre les plaques (1) leurs faces supérieures présentent des plots (28) qui pénètrent dans des creux (29) situés sur leurs faces inférieures.The longitudinal members (22) of the frame (20) which is used in the horizontal position have a section, for example in coated T. in order to be housed by their horizontal wing (22a) in a recessed area (26) of the underside of the plates (1) and to penetrate by their upper (22b) and lower (22c) wings into grooves (27) provided in the lower and upper faces of the plates (1). For a good connection to be made between the plates (1) their upper faces have studs (28) which penetrate into recesses (29) located on their lower faces.

Quant au cadre (21) de chaque ensemble (16), il présente une largeur inférieure afin de pouvoir se loger dans l'espace délimité par les plaques (1) ; ses longerons (24) ont par exemple une section en L ou en U. et la traverse extrême (25) de chaque cadre (21) comporte deux zones (30) qui sont aménagées en forme de crochets ou de clips et sont destinées à coopérer avec les deux zones décrochées (19) de la traverse correspondante (1S) de l'élément ou écarteur de base (15), et à servir au positionnement en butée des armatures horizontales.As for the frame (21) of each assembly (16), it has a smaller width in order to be able to be accommodated in the space delimited by the plates (1); its side members (24) have for example an L or U section. and the end crosspiece (25) of each frame (21) comprises two zones (30) which are arranged in the form of hooks or clips and are intended to cooperate with the two off-hook zones (19) of the corresponding crosspiece (1S) of the base element or spacer (15), and to be used for positioning the horizontal reinforcements in abutment.

Il est toutefois à remarquer, et cela est essentiel, que les traverses (23) du cadre (20) présentent, elles aussi, deux zones décrochées (31) identiques à celles (19) des éléments de base (15). Grâce à cet agencement, chaque ensemble (16) peut donc, par son cadre (21) coopérer soit avec un élément de base (15), soit avec un ensemble (16) situé plus haut.It should be noted, however, and this is essential, that the crosspieces (23) of the frame (20) also have two off-hook zones (31) identical to those (19) of the base elements (15). Thanks to this arrangement, each assembly (16) can therefore, by its frame (21) cooperate either with a base element (15), or with an assembly (16) located higher.

En raison de leur agencement, les ensembles (16) permettent, en combinaison avec les éléments de base (15) et avec les plaques (1), de réaliser un coffrage perdu dans lequel des plaques auront, sur toute la hauteur du coffrage, un écartement déterminé par les éléments (15) et les ensembles (16) et dans lequel ces ensembles (16) apporteront au coffrage la rigidité nécessaire, en raison d'une part, de la bonne liaison des ensembles (16) avec les plaques (1) et en raison, d'autre part, du verrouillage de la totalité des ensembles, des plaques et des armatures les uns par rapport aux autres, grâce à la coopération du cadre vertical (21) de chaque ensemble (16) avec un cadre horizontal (20) solidaire d'une plaque (1).Due to their arrangement, the assemblies (16) make it possible, in combination with the basic elements (15) and with the plates (1), to produce a lost formwork in which plates will have, over the entire height of the formwork, a spacing determined by the elements (15) and the assemblies (16) and in which these assemblies (16) will provide the formwork with the necessary rigidity, due on the one hand, to the good connection of the assemblies (16) with the plates (1 ) and due, on the other hand, to the locking of all of the assemblies, of the plates and of the reinforcements with respect to each other, thanks to the cooperation of the vertical frame (21) of each assembly (16) with a horizontal frame (20) secured to a plate (1).

Les cadres inférieurs (21) des ensembles (16) présentent, par ailleurs, pour avantage de permettre facilement la construction des linteaux.The lower frames (21) of the assemblies (16) have, moreover, the advantage of easily allowing the construction of the lintels.

Comme le montrent les figures 16 et 17 des panneaux de fermeture (32) peuvent en effet être posés sur des éléments (33) identiques aux éléments de base (15), lesquels éléments (33) présentent des traverses avec lesquelles viennent en prise les crochets aménagés sur la traverse inférieure des cadres (21) qui font partie des ensembles 5 (16) solidaires des plaques (I). Les panneaux de fermeture (32) peuvent comporter des saillies (34) présentant des encoches (35) pour permettre le positionnement d'armatures de ferraillage du linteau.As shown in Figures 16 and 17 closure panels (32) can indeed be placed on elements (33) identical to the base elements (15), which elements (33) have crosspieces with which the hooks engage arranged on the lower cross member of the frames (21) which form part of the assemblies 5 (16) integral with the plates (I). The closure panels (32) may include projections (34) having notches (35) to allow the positioning of lintel reinforcement frames.

Les extrémités du coffrage au niveau d'ouvertures telles que fenêtres et portes sont fermées à l'aide de plaques (36), de structure 0 identique à celle des plaques (I). Comme montré aux figures 18 et 19, la plaque (36) est conformée de façon à posséder une partie (37) s'emboîtant entre deux plaques latérales (1) et une partie (38) en débord de celle-ci. Cette partie présente un prolongement latéral (39) destiné à recouvrir l'extrémité de l'une des plaques latérales (1). L'autre bord 5 de la plaque (3S) délimite avec l'extrémité de l'autre plaque latérale une feuillure (40) destinée au montage de l'huisserie devant équiper l'ouverture considérée. Afin de permettre une variation en vue du réglage de la largeur du tableau de cette ouverture, les plaques de fermeture (36) peuvent être plus ou moins enfoncées entre les plaques latérales (1).The ends of the formwork at the level of openings such as windows and doors are closed using plates (36), of structure 0 identical to that of the plates (I). As shown in Figures 18 and 19, the plate (36) is shaped so as to have a part (37) which fits between two side plates (1) and a part (38) projecting therefrom. This part has a lateral extension (39) intended to cover the end of one of the side plates (1). The other edge 5 of the plate (3S) delimits with the end of the other side plate a rebate (40) intended for mounting the frame to equip the opening considered. To allow variation for adjustment of the width of the table of this opening, the closure plates (36) can be more or less pressed between the side plates (1).

A cet effet, dans les parois supérieure et inférieure des plaques (36) sont ménagées plusieurs rainures longitudinales parallèles (41) permettant l'engagement des traverses (18,23) des cadres (13,20). En fonction de la position des traverses (18,23) dans les rainures (41) , la partie (37) de la plaque (36) est plus ou moins enfoncée dans le coffrage. La figure 20 représente une plaque (36) à trois rainures (41), dans les rainures intermédiaires de laquelle sont engagées les traverses (18,23). Afin de permettre le réglage de la position d'une plaque (36), il convient d'adapter l'épaisseur de son aile (39), par enlèvement de matière, sur le chantier, ce qui est facilité par le ménagement de rainures latérales et verticales (42) indiquant les lignes de découpe.For this purpose, in the upper and lower walls of the plates (36) are formed several parallel longitudinal grooves (41) allowing the engagement of the crosspieces (18,23) of the frames (13,20). Depending on the position of the crosspieces (18,23) in the grooves (41), the part (37) of the plate (36) is more or less pressed into the formwork. Figure 20 shows a plate (36) with three grooves (41), in the intermediate grooves of which are engaged the crosspieces (18,23). In order to allow the adjustment of the position of a plate (36), it is advisable to adapt the thickness of its wing (39), by removal of material, on the site, which is facilitated by the provision of lateral grooves and vertical (42) indicating the cutting lines.

La figure 21 du dessin représente un angle de coffrage dans lequel les plaques de coffrage sont tenues par des pièces (45) de structure en échelle, ayant une forme en L. Les éléments (44), (45) correspondant aux longerons sont en forme de L et sont entretoisés par des traverses (46) avec ménagement dans l'angle d'un passage pour une armature verticale d'angle (47).Figure 21 of the drawing shows a formwork angle in which the formwork plates are held by parts (45) of ladder structure, having an L shape. The elements (44), (45) corresponding to the side members are in shape of L and are braced by crosspieces (46) with care in the angle of a passage for a vertical angle frame (47).
