Description

Dans le domaine du bâtiment et des travaux publics, il est largement 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 widely 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.

C'est ainsi que le US-A-3 562991, le FR-A-2 328 814 et le GB-A-1 589 113 (ce document décrivant un système constructif selon le préambule de la revendication 1 ) décrivent des systèmes constructifs dans lesquels des panneaux sont assemblés deux par deux en position écartée parallèlement l'un à l'autre, sont alignés pour former des rangées horizontales et sont superposés verticalement. Avec de tels systèmes, il est possible de réaliser des coffrages dans lesquels est coulé le béton constituant le corps d'un mur; et ces murs présentent de bons coefficients d'isolation thermique, sous réserve que les panneaux soient préfabriqués en un matériau isolant.Thus, US-A-3 562991, FR-A-2 328 814 and GB-A-1 589 113 (this document describing a constructive system according to the preamble of claim 1) describe constructive systems in which of the panels are assembled two by two in a spaced position parallel to each other, are aligned to form horizontal rows and are superimposed vertically. With such systems, it is possible to produce forms in which the concrete constituting the body of a wall is poured; and these walls have good thermal insulation coefficients, provided that the panels are prefabricated in an insulating material.

Il s'avère toutefois que dans ces systèmes constructifs, le montage du coffrage au moyen des panneaux n'est pas commode, car il nécessite l'utilisation de nombreuses pièces de liaison dont certaines sont en forme d'échelles horizontales et d'échelles verticales. Le plus souvent, ces échelles sont indépendantes, ce qui complique le montage. Dans d'autres cas, comme dans le GB-A-1 589 113, les échelles horizontales et celles verticales sont pré- assemblées, mais il s'agit alors là de véritables charpentes qui sont lourdes et encombrantes et dont le stockage et le transport entraînent des difficultés et une augmentation du coût final de la construction.However, it turns out that in these constructive systems, the assembly of the formwork by means of the panels is not convenient, because it requires the use of numerous connecting pieces, some of which are in the form of horizontal and vertical scales. . Most often, these scales are independent, which complicates assembly. In other cases, as in GB-A-1 589 113, the horizontal and vertical ladders are pre-assembled, but these are real frames which are heavy and bulky and whose storage and transport lead to difficulties and an increase in the final cost of construction.

L'invention remédie à ces inconvénients. Elle a pour objet un système constructif qui est du dernier type rappelé, dans lequel des panneaux isolants ou non sont associés à des échelles horizontales déterminant l'écartement des panneaux et reliées à des échelles verticales servant d'éléments raidisseurs, mais dans le système conforme à l'invention, les échelles ont un agencement tel que le coffrage est facile à monter et présente une rigidité et une tenue grâce auxquelles il devient possible de construire en une seule phase des murs de grande hauteur.The invention overcomes these drawbacks. It relates to a constructive system which is of the last type mentioned, in which insulating panels or not are associated with horizontal scales determining the spacing of the panels and connected to vertical scales serving as stiffening elements, but in the compliant system In the invention, the ladders have an arrangement such that the formwork is easy to assemble and has a rigidity and a strength thanks to which it becomes possible to build in a single phase walls of great height.

Conformément à l'invention, chaque échelle horizontale est plus large que l'échelle verticale à laquelle elle est associée, est placée au-dessus de cette dernière et prend appui sur la face supérieure d'un panneau ou d'une rangée de panneaux, alors que l'échelle verticale qui lui est reliée est logée entre deux rangées de panneaux opposés qu'elle maintient chaque échelle étant formée par au moins deux longerons et par deux traverses, la traverse inférieure de l'échelle verticale comporte des moyens pour son accrochage à des moyens complémentaires prévus sur la traverse correspondante de l'échelle horizontale sous-jacente, et les deux longerons de chaque échelle horizontale ont une section en T couché et se logent par leur aile horizontale dans une zone en retrait de la face inférieure des panneaux et pénètrent par leurs ailes verticales supérieure et inférieure dans des rainures aménagées dans les faces inférieure et supérieure des panneaux; et la face supérieure de chaque panneau présente des plots entre lesquels passent les traverses de chaque échelle horizontale supérieure.In accordance with the invention, each horizontal scale is wider than the vertical scale with which it is associated, is placed above the latter and is supported on the upper face of a panel or a row of panels, while the vertical ladder which is connected to it is housed between two rows of opposite panels which it maintains each ladder being formed by at least two longitudinal members and by two crosspieces, the lower crossmember of the vertical ladder comprises means for its attachment to additional means provided on the corresponding cross member of the underlying horizontal ladder, and the two side members of each horizontal ladder have a coated T-section and are housed by their horizontal wing in an area set back from the underside of the panels and penetrate by their upper and lower vertical wings into grooves provided in the lower and upper faces of the panels; and the upper face of each panel has studs between which pass the crosspieces of each upper horizontal scale.

Suivant une forme de réalisation, chaque échelle horizontale et chaque échelle verticale sont indépendantes, mais comportent des moyens de liaison l'une à l'autre.According to one embodiment, each horizontal scale and each vertical scale are independent, but comprise means of connection to each other.

Dans une autre forme plus avantageuse d'execution, chaque échelle verticale est articulée au niveau de l'une de ses traverses à la traverse correspondante d'une échelle supérieure horizontale.In another more advantageous form of execution, each vertical scale is articulated at one of its crosspieces to the corresponding crosspiece of a horizontal top scale.

Suivant une autre caractéristique de ce système constructif, les traverses de chaque échelle horizontale comportent des encoches ouvertes vers le haut et servant de logements aux fers d'armature du mur qui sont bloqués au fond de ces encoches par la traverse inférieure de l'échelle verticale située au-dessus.According to another characteristic of this construction system, the crosspieces of each horizontal ladder have notches open upwards and serving as housings for the reinforcing bars of the wall which are blocked at the bottom of these notches by the lower crosspiece of the vertical ladder located above.

Le dessin schématique annexé représente, à titre d'exemple non limitatif, une forme d'exécution de ce système constructif:

  • Figure 1 est une vue en perspective d'une portion de coffrage dans une zone destinée à constituer une portion de mur;
  • Figures 2 et 3 sont, à plus grande échelle, des vues partielles en perspective montrant respectivement la face supérieure et la face inférieure d'un panneau;
  • Figure 4 est une vue en perspective d'un ensemble de rigidification entrant dans la constitution de ce coffrage, représenté en position de stockage ou de transport;
  • Figure 5 en est une vue en perspective en position d'utilisation, avant mise en place dans le coffrage;
  • Figure 6 est, à plus grande échelle, une vue en coupe suivant 6 - 6 de figure 5.
  • La figure 1 représente un coffrage destiné à la construction d'un mur. Ce coffrage est de type "perdu" en ce sens qu'il demeure définitivement attenant au mur après sa construction. Il est constitué par des panneaux (1) et par une pluralité d'ensembles de rigidification (16).
The appended schematic drawing represents, by way of nonlimiting example, an embodiment of this constructive system:
  • Figure 1 is a perspective view of a portion of formwork in an area intended to constitute a portion of wall;
  • Figures 2 and 3 are, on a larger scale, partial perspective views showing respectively the upper face and the lower face of a panel;
  • Figure 4 is a perspective view of a stiffening assembly forming part of this formwork, shown in the storage or transport position;
  • Figure 5 is a perspective view in the position of use, before placement in the formwork;
  • Figure 6 is, on a larger scale, a sectional view along 6 - 6 of Figure 5.
  • Figure 1 shows a formwork for the construction of a wall. This formwork is of the "lost" type in the sense that it remains permanently attached to the wall after its construction. It consists of panels (1) and a plurality of stiffening assemblies (16).

Les panneaux de coffrage (1) sont constitués en une matière isolante de résistance appropriée à la nature du matériau coulé pour la réalisation du mur. Cette matière de préférence de haute densité peut être par exemple du polystyrène expansé, de la mousse de polystyrène extrudée, de la mousse de polyuréthane, de la mousse phénolique.... Dans la masse du panneau (1) peut être prévue une armature 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 à claire voie, par exemple panneau de contre plaqué ou de bois compressé, fibre de verre, grillage, treillis soudé, tissu synthétique....The formwork panels (1) are made of an insulating material of resistance appropriate to the nature of the material poured for the realization of the wall. This preferably high-density material may for example be expanded polystyrene, extruded polystyrene foam, polyurethane foam, phenolic foam, etc. In the mass of the panel (1), a framework may be provided. by a resistant soul. This core can be produced by increasing the molecular density of the insulating material, or by interposing a solid or clear sheet, for example plywood or compressed wood panel, fiber glass, mesh, welded mesh, synthetic fabric ....

Les ensembles de rigidification (16) coopérant avec les panneaux (1) sont assimilables à des échelles respectivement horizontale (20) et verticale (21) qui ont chacune une forme de cadre rectangulaire constitué par deux longerons et par deux traverses.The stiffening assemblies (16) cooperating with the panels (1) can be likened to respectively horizontal (20) and vertical (21) scales which each have the shape of a rectangular frame constituted by two longitudinal members and by two crosspieces.

Pour l'échelle horizontale (20), les longerons sont désignés par (22) et les traverses sont désignées par (23); et pour l'échelle verticale (21), les longerons sont désignés par (24) et les traverses par (25). Ces deux échelles (20) et (21) présentent la particularité d'être articulées l'une à l'autre au niveau d'une traverse (23) de l'une et d'une traverse (25) de l'autre.For the horizontal ladder (20), the side members are designated by (22) and the cross members are designated by (23); and for the vertical ladder (21), the side members are designated by (24) and the cross members by (25). These two scales (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.

Cette articulation peut être réalisée de façon quelconque. Que que soit son agencement, elle permet à l'échelle (21) dont la largeur est inférieure à celle de l'échelle (20) d'être incluse dans cette dernière, comme le montre la figure 4, ou d'occuper une position perpendiculaire à elle, comme le montre la figure 5. 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) de l'échelle (21) vient, en même temps qu'elle s'accroche à la traverse (18, 23) d'une échelle (20) située en dessous, verrouiller les armatures métalliques (23c) positionnées dans les encoches (23b) des traverses (23).This articulation can be carried out in any way. Whatever its arrangement, it allows the ladder (21) whose width is less than that of the ladder (20) to be included in the latter, as shown in Figure 4, or to occupy a position perpendicular to it, as shown in Figure 5. 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 crossmember (25) of the ladder (21) comes, at the same time as it hooks to the crossmember (18, 23) of a ladder (20) located below, to lock the metal reinforcements (23c) positioned in the notches (23b) of the crosspieces (23).

Les longerons (22) de l'échelle (20) qui est utilisée en position horizontale ont une section, 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 panneaux (1). Pour qu'une bonne liaison soit réalisée entre les panneaux (1), leurs faces supérieures présentent des plots (28) qui pénètrent dans des creux (29) situés sur leurs faces inférieures.The side members (22) of the ladder (20) which is used in the horizontal position have a section, in a coated T, in order to be housed by their horizontal wing (22a) in a recessed area (26) on the underside of the plates (1) and penetrate through their upper (22b) and lower (22c) wings into grooves (27) provided in the lower and upper faces of the panels (1). For a good connection to be made between the panels (1), their upper faces have studs (28) which penetrate into recesses (29) located on their lower faces.

Quant à l'échelle verticale (21) de chaque ensemble de rigidification (16), elle présente une largeur inférieure afin de pouvoir se loger dans l'espace délimité par les panneaux (1). Ses longerons (24) ont par exemple une section en L ou en U, et la traverse extrême (25) de chaque échelle (21) comporte deux zones (30) qui sont aménagées en forme de crochets ou de clips, et sont destinées à coopérer avec deux zones décrochées (31) aménagées dans la traverse (23) de l'échelle horizontale sous-jacente (20).As for the vertical scale (21) of each stiffening assembly (16), it has a smaller width in order to be able to be accommodated in the space delimited by the panels (1). Its longitudinal members (24) have for example an L or U section, and the end crosspiece (25) of each ladder (21) comprises two zones (30) which are arranged in the form of hooks or clips, and are intended to cooperate with two off-hook zones (31) arranged in the crosspiece (23) of the underlying horizontal ladder (20).

En raison de leur agencement, les ensembles de rigidification (16) permettent, en combinaison avec des éléments de base (15) visibles à la figure 1, et avec les panneaux (1), de réaliser un coffrage perdu dans lequel les panneaux (1) auront, sur toute la hauteur du coffrage, un écartement déterminé par les éléments (15) et par 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 panneaux (1) et en raison, d'autre part du verrouillage de la totalité des ensembles (16), des panneaux (1) et des armatures (23c) les uns par rapport aux autres grâce à la coopération de l'échelle verticale (21) de chaque ensemble de rigidification (16) avec une échelle horizontale (20) qui en est solidaire, mais est aussi solidaire de deux panneaux opposés.Due to their arrangement, the stiffening assemblies (16) allow, in combination with basic elements (15) visible in Figure 1, and with the panels (1), to produce a lost formwork in which the panels (1 ) will have, over the entire height of the formwork, a spacing determined by the elements (15) and by the assemblies (16), and in which these assemblies (16) will bring the necessary rigidity to the formwork, due to a part of the good connection of the assemblies (16) with the panels (1) and due, on the other hand, to the locking of all of the assemblies (16), of the panels (1) and of the frames (23c) with respect to each other thanks to to the cooperation of the vertical ladder (21) of each stiffening assembly (16) with a horizontal ladder (20) which is integral with it, but is also integral with two opposite panels.
