Abstract

The shuttering is made from a series of adjacent rock wool panels (l1, l2) with anchoring elements (E1, E'1, E2, E'2) for reinforcing mesh (T) on one side and metal reinforcing sheets (1) on the other. The metal sheets, made from galvanised steel, have raised sides (3, 4) and turned-over horizontal edges (7) that engage with slots in the rock wool panels. The base of each metal sheet has lengthwise stiffening ribs, while its turned-over edges have V-section locking ribs (30).

Description

La présente invention concerne un coffrage isolant pour la construction de parois en béton, telles qu'un plancher, une toiture ou un mur de bâtiment.The present invention relates to an insulating form for the construction of concrete walls, such as a floor, a roof or a building wall.

Ces éléments de bâtiments peuvent notamment être utilisés pour la construction d'habitations, d'hôtels, d'hôpitaux, de bâtiments industriels ou de parkings, sans pour autant y être limités.These building elements can be used in particular for the construction of houses, hotels, hospitals, industrial buildings or car parks, without being limited thereto.

Il est connu, notamment par EP 0 427 596 , de réaliser un coffrage pour plancher en béton comprenant une multiplicité de panneaux de laine de roche mutuellement juxtaposés munis d'éléments d'ancrage faisant saillie sur leur face supérieure, et reposant par leur face inférieure sur une table de coffrage constituée de panneaux de bois. Une dalle de béton est coulée sur les panneaux isolants en noyant les éléments d'ancrage pour solidariser les panneaux isolants au béton après durcissement. La table de coffrage est ensuite retirée.He is known, particularly by EP 0 427 596 , to realize a concrete floor formwork comprising a multiplicity of mutually juxtaposed rock wool panels provided with anchoring elements projecting from their upper face, and resting by their underside on a formwork table made of wood panels . A concrete slab is poured on the insulating panels by embedding the anchoring elements to secure the insulating panels to concrete after hardening. The formwork table is then removed.

La fabrication, le transport, le montage, le démontage et le nettoyage de la table de coffrage sont des opérations coûteuses. De plus la face inférieure des panneaux de laine de roche, apparente sur le plancher fini, est peu esthétique.The manufacture, transport, assembly, disassembly and cleaning of the formwork table are expensive operations. In addition, the underside of rockwool panels, which is visible on the finished floor, is not very aesthetic.

EP 1 215 346 décrit un plancher comprenant notamment une succession de profilés métalliques emboîtés les uns dans les autres et garnis chacun de blocs d'isolant, l'isolation thermique étant complétée par une lame d'air entre le fond du profilé et le bloc d'isolant. Un treillis métallique est fixé sur les profilés, et une dalle de béton est coulée sur l'ensemble. L'isolant est séparé du béton par la lame d'air et c'est le profilé métallique qui est ancré au béton, créant ainsi des ponts thermiques néfastes à l'isolation thermique du plancher. EP 1 215 346 describes a floor including in particular a succession of metal profiles nested in each other and each lined with insulation blocks, the thermal insulation being completed by an air gap between the bottom of the profile and the insulation block. A wire mesh is fixed on the profiles, and a concrete slab is poured on the whole. The insulation is separated from the concrete by the air gap and it is the metal profile that is anchored to the concrete, creating thermal bridges harmful to the thermal insulation of the floor.

Le plancher décrit dans EP 1 215 346 peut constituer en particulier un plancher collaborant, c'est-à-dire un plancher dans lequel le coffrage reste à demeure et lui apporte, une fois construit, les propriétés mécaniques en traction et flexion de ses composants en métal, tels que de l'acier galvanisé ou non.The floor described in EP 1 215 346 may in particular constitute a collaborating floor, that is to say a floor in which the formwork remains permanently and brings him, once built, the mechanical properties in traction and bending of its metal components, such as galvanized steel or not.

Le but de la présente invention est donc de mettre à disposition un profilé, un panneau isolant et un coffrage intégrant ceux-ci, remédiant aux inconvénients des systèmes de l'art antérieur et permettant en particulier de construire des parois en béton sans créer de ponts thermiques.The purpose of the present invention is therefore to provide a profile, an insulating panel and a formwork incorporating them, overcoming the drawbacks of the systems of the prior art and allowing in particular to build concrete walls without creating bridges thermal.

À cet effet, un premier objet de la présente invention est constitué par un coffrage pour paroi en béton comprenant une multiplicité de panneaux de matière isolante mutuellement juxtaposés munis d'éléments d'ancrage faisant saillie sur une première face principale, et un support de coffrage rigide recouvrant la face principale opposée des panneaux, formé par des profilés métalliques définissant chacun le fond et les deux côtés d'un canal qui est rempli par au moins un panneau isolant, l'épaisseur de ce dernier étant supérieure à la hauteur du profilé, les profilés étant mutuellement positionnés côte à côte par la coopération de rebords formés sur les deux côtés du canal et logés dans des évidements en forme d'encoches d'une largeur appropriée (dans la direction de l'épaisseur des panneaux) ménagés dans un flanc des panneaux isolants.For this purpose, a first object of the present invention is constituted by a formwork for a concrete wall comprising a plurality of juxtaposed insulating material panels provided with anchoring elements projecting from a first main face, and a formwork support rigid covering the opposite main face of the panels, formed by metal profiles each defining the bottom and the two sides of a channel which is filled by at least one insulating panel, the thickness of the latter being greater than the height of the profile, the profiles being mutually positioned side by side by the cooperation of flanges formed on both sides of the channel and housed in slot-shaped recesses of appropriate width (in the direction of the thickness of the panels) formed in a flank insulating panels.

  • Les premier et second rebords s'étendent sensiblement parallèlement au plan de la plage centrale.
  • Les moyens de positionnement mutuel comprennent un retour faisant suite au premier rebord, tourné à l'opposé de la seconde aile et formant avec le premier rebord un logement dans lequel s'insère le second rebord du profilé voisin.
  • Les moyens de positionnement mutuel comprennent des profils s'interpénétrant, notamment en V, formés sur le premier rebord d'un profilé et sur le second rebord du profilé voisin.
  • Pour réaliser un plancher en béton reposant sur des poutres horizontales parallèles, les deux extrémités de chaque profilé s'appuient directement ou indirectement sur deux poutres voisines respectivement.

Un second objet de l'invention est constitué par un module pour la réalisation d'un coffrage pour paroi en béton, comprenant un profilé et au moins un panneau isolant tels que définis plus haut, le canal du profilé étant rempli par le ou les panneaux isolants et un rebord du profilé étant logé dans les évidements en forme d'encoches.A second object of the invention is constituted by a module for producing a formwork for a concrete wall, comprising a profile and at least one insulating panel as defined above, the channel of the profile being filled by the panel or panels insulators and a flange of the profile being housed in the recesses in the form of notches.

L'invention à encore pour objets un profilé métallique et un panneau isolant propres à faire partie du coffrage susmentionné.The invention still further objects a metal profile and an insulating panel suitable to be part of the formwork mentioned above.

Un tel panneau isolant présente dans un de ses flancs un évidement longitudinal en forme d'encoche, le flanc opposé étant sensiblement plat ou présentant lui aussi un évidement longitudinal en forme d'encoche.Such an insulating panel has in one of its flanks a longitudinal recess in the form of a notch, the opposite flank being substantially flat or also having a longitudinal slot-shaped recess.

D'autres caractéristiques et avantages de l'invention apparaîtront à la lecture de la description qui va suivre, donnée uniquement à titre d'exemple et faite en se référant aux dessins annexés sur lesquels :

  • la figure 1 est une vue en coupe d'un profilé selon l'invention,
  • la figure 2 est une vue en perspective d'un plancher en béton selon l'invention, en cours de réalisation,
  • la figure 3 est une vue schématique en coupe d'un plancher en béton selon l'invention.
Other features and advantages of the invention will appear on reading the description which follows, given solely by way of example and with reference to the appended drawings in which:
  • FIG. 1 is a sectional view of a section according to the invention,
  • FIG. 2 is a perspective view of a concrete floor according to the invention, in progress,
  • Figure 3 is a schematic sectional view of a concrete floor according to the invention.

Comme on peut le voir sur la figure 1, le profilé 1 selon l'invention comprend une plage centrale 2 sensiblement plane et deux ailes 3 et 4 s'étendant sensiblement perpendiculairement au plan de la plage centrale 2, celle-ci et les ailes 3 et 4 formant respectivement le fond et les côtés d'un canal. La plage centrale 2 est par exemple munie de nervures longitudinales 5, 5' et 5' ' ayant des effets raidisseur et esthétique.As can be seen in FIG. 1, the profile 1 according to the invention comprises a substantially planar central zone 2 and two wings 3 and 4 extending substantially perpendicular to the plane of the central zone 2, the latter and the wings 3 and 4 respectively forming the bottom and the sides of a channel. The central area 2 is for example provided with longitudinal ribs 5, 5 'and 5' 'having stiffening and aesthetic effects.

Dans un mode de réalisation non représenté, la plage centrale 2 est munie de perforations destinées à favoriser l'action d'absorption acoustique de l'isolant. L'épaisseur du profilé 1 est choisie de manière à préserver sa rigidité malgré la présence des perforations, celles-ci étant en outre de préférence disposées sur une partie seulement de la plage centrale 2, notamment sur certaines des bandes longitudinales définies par les nervures 5, 5' et 5".In an embodiment not shown, the central area 2 is provided with perforations intended to promote the acoustic absorption action of the insulation. The thickness of the section 1 is chosen so as to preserve its rigidity despite the presence of the perforations, these being moreover preferably disposed on only part of the central zone 2, in particular on some of the longitudinal bands defined by the ribs 5. , 5 'and 5 ".

Une première aile 3 du profilé 1 présente une hauteur inférieure à la largeur du profilé 1 et se raccorde à son extrémité à un premier rebord 6 s'étendant sensiblement selon un plan parallèle au plan de la plage centrale 2, et tourné en direction de la seconde aile 4. Un coude relie le premier rebord 6 à un retour 7 tourné à l'opposé de la seconde aile 4, plus éloigné du plan de la plage centrale 2 que le premier rebord 6. Le retour 7 est représenté comme étant parallèle au rebord 6, mais, selon une variante avantageuse, il forme avec ce dernier un angle aigu d'environ 15° par exemple.A first flange 3 of the profile 1 has a height less than the width of the profile 1 and is connected at its end to a first rim 6 extending substantially in a plane parallel to the plane of the central strip 2, and turned towards the second wing 4. An elbow connects the first flange 6 to a return 7 turned away from the second flange 4, further from the plane of the central area 2 than the first flange 6. The return 7 is shown as being parallel to the flange 6, but, according to an advantageous variant, it forms with the latter an acute angle of about 15 ° for example.

Sensiblement à mi-largeur, et entre l'extrémité du retour 7 et l'aile 3 dans la direction de la largeur de la plage centrale 2, le rebord 6 est plié selon un profil en V 8 dont la pointe est orientée vers le bas.At substantially mid-width, and between the end of the return 7 and the flange 3 in the width direction of the central area 2, the flange 6 is folded according to a V-shaped profile 8 whose tip is directed downwards. .

À l'autre extrémité de la plage centrale 2, la seconde âme 4 se raccorde à son extrémité à un second rebord 9 s'étendant sensiblement selon un plan parallèle au plan de la plage centrale 2, et tourné à l'opposé de la première aile 3. Le rebord 9 comporte un profil en V 10 identique à celui du premier rebord.At the other end of the central zone 2, the second core 4 is connected at its end to a second flange 9 extending substantially in a plane parallel to the plane of the central zone 2, and turned away from the first one. wing 3. The flange 9 has a V-shaped profile 10 identical to that of the first flange.

Le profilé 1 est métallique et de préférence réalisé en acier galvanisé, ce qui permet d'apporter une bonne résistance à la corrosion à l'ensemble. En outre, la face extérieure qui restera apparente présente ainsi un aspect esthétique, ne nécessitant pas obligatoirement de décoration supplémentaire, en fonction de l'usage final de la paroi.The profile 1 is metallic and preferably made of galvanized steel, which makes it possible to provide good corrosion resistance to the assembly. In addition, the outer face which will remain apparent thus has an aesthetic appearance, not necessarily requiring additional decoration, depending on the final use of the wall.

On peut voir sur la figure 2 la façon d'utiliser les profilés selon l'invention pour réaliser un coffrage selon l'invention, puis une paroi en béton selon l'invention, comme un plancher tel que représenté en figure 3.FIG. 2 shows how to use the profiles according to the invention to produce a formwork according to the invention, and then a concrete wall according to the invention, such as a floor as shown in FIG.

On voit sur la figure 2 un premier profilé 1 identique à celui décrit en figure 1, ainsi qu'un profilé 20 identique au profilé 1 et comportant notamment une seconde aile 24 et un second rebord 29 identiques à l'aile 4 et au rebord 9.FIG. 2 shows a first profile 1 identical to that described in FIG. 1, as well as a profile 20 identical to profile 1 and comprising in particular a second flange 24 and a second flange 29 identical to flange 4 and flange 9. .

On introduit tout d'abord un premier panneau de matière isolante I1 à l'intérieur du profilé 1, la hauteur (l'épaisseur) du panneau I1 étant supérieure à la hauteur du premier profilé 1. En outre, un des flancs du panneau I1 a été préalablement entaillé horizontalement à hauteur du premier rebord 6. Le panneau I1 est placé dans le profilé 1 de sorte que le premier rebord 6 du profilé 1 soit entièrement inséré dans l'entaille du panneau I1. Le flanc opposé peut être sensiblement plan, ou présenter une entaille semblable de manière à permettre l'insertion du panneau dans le profilé indifféremment dans un sens ou dans l'autre. Plusieurs panneaux tels que I1 peuvent être alignés de manière jointive sur la longueur du profilé 1, en fonction des longueurs respectives du profilé et des panneaux.Firstly, a first insulating material panel I1 is introduced inside the section 1, the height (the thickness) of the panel I1 being greater than the height of the first profile 1. In addition, one of the sides of the panel I1 has been cut horizontally at the height of the first 6. The panel I1 is placed in the profile 1 so that the first edge 6 of the profile 1 is fully inserted into the notch of the panel I1. The opposite flank may be substantially flat, or have a similar notch so as to allow the insertion of the panel in the section indifferently in one direction or the other. Several panels such as I1 may be aligned in a contiguous manner along the length of the profile 1, depending on the respective lengths of the profile and the panels.

On procède de façon identique avec le second profilé 20 que l'on garnit d'un ou plusieurs panneaux de matière isolante 12. On répète l'opération avec autant de profilés identiques aux profilés 1 et 20 que nécessaire.The same procedure is carried out with the second section 20 which is filled with one or more panels of insulating material 12. The operation is repeated with as many profiles as the profiles 1 and 20 as necessary.

Les panneaux I1 et I2 peuvent être tous panneaux isolants rigides tels que définis dans (à compléter), notamment des panneaux en laine minérale telle que laine de roche ou laine de verre, ou des panneaux en matière plastique cellulaire telle que polystyrène ou polyuréthanne. De façon plus particulière, ils peuvent être en laine de roche dont la masse volumique n'est pas uniforme dans l'épaisseur des panneaux et est plus élevée dans une zone adjacente à leur face supérieure, tournée à l'opposé des plages centrales 2, 22, que sur le reste de leur épaisseur.The panels I1 and I2 can be any rigid insulating panels as defined in (to be completed), including mineral wool panels such as rock wool or glass wool, or panels of cellular plastic such as polystyrene or polyurethane. More particularly, they may be stone wool whose density is not uniform in the thickness of the panels and is higher in an area adjacent to their upper face, facing away from the central areas 2, 22, only on the rest of their thickness.

Les panneaux I1 et I2 comportent sur leur face supérieure des éléments d'ancrage E1, E1', E2, E2' intégrés. Ces éléments d'ancrage sont, par exemple, constitués de ressorts métalliques en spirale. La quantité des éléments d'ancrage dépend de différents paramètres dont la largeur des panneaux I1 et 12.The panels I1 and I2 have on their upper face integrated anchoring elements E1, E1 ', E2, E2'. These anchoring elements are, for example, made of spiral metal springs. The quantity of the anchoring elements depends on various parameters including the width of the panels I1 and 12.

On procède ensuite à l'assemblage des profilés 1 et 20 comme suit. Le second rebord 29 du second profilé 20 est inséré obliquement dans le dièdre aigu formé par le premier rebord 6 et le retour 7 du premier profilé 1, puis on fait pivoter le profilé 20 de manière à amener le rebord 29 en appui sur le rebord 6. Les ailes et les rebords sont dimensionnés de telle sorte que les profils en V 8 et 30 des rebords 6 et 29 des profilés 1 et 20 s'imbriquent l'un dans l'autre tandis que les ailes 3 et 24 sont mutuellement accolées et que les plages centrales 2 et 22 s'étendent sensiblement dans le même plan. Les profils en V 8 et 30 coopèrent alors pour bloquer tout mouvement de translation relatif des profilés 1, 20 dans un plan parallèle à celui des plages centrales 2 et 22, tandis que le rebord 29 est immobilisé perpendiculairement à ce plan dans le logement formé par le rebord 6 et le retour 7.The profiles 1 and 20 are then assembled as follows. The second flange 29 of the second profile 20 is inserted obliquely into the acute dihedral formed by the first flange 6 and the return 7 of the first section 1, then the profile 20 is rotated so as to bring the flange 29 resting on the flange 6 The wings and flanges are dimensioned so that the V-shaped profiles 8 and 30 of the flanges 6 and 29 of the profiles 1 and 20 fit into one another while the flanges 3 and 24 are mutually contiguous and that the central beaches 2 and 22 extend substantially in the same plane. The V-shaped profiles 8 and 30 then cooperate to block any relative translational movement of the sections 1, 20 in a plane parallel to that of the central areas 2 and 22, while the flange 29 is immobilized perpendicularly to this plane in the housing formed by flange 6 and return 7.

On voit que les panneaux de laine de roche I1 et I2 forment alors une couche continue au-dessus des profilés 1 et 20, supprimant ainsi toute possibilité de création de ponts thermiques.It is seen that the rock wool panels I1 and I2 then form a continuous layer above the sections 1 and 20, thus eliminating any possibility of creating thermal bridges.

Pour terminer la réalisation de la paroi en béton, on place ensuite un treillis métallique T sur des cales d'épaisseur non représentées, avantageusement en matière plastique, qui peuvent être solidaires des éléments d'ancrage E1, E1', E2, E2', comme décrit dans FR 2 624 154 A , ou indépendantes de ceux-ci, ces cales d'épaisseur reposant sur les panneaux I1 et I2 et maintenant le treillis écarté des éléments d'ancrage et à une distance d'environ 3 cm de la surface des panneaux. Ces cales sont de préférence de grande longueur pour répartir le poids des personnes qui circulent sur le treillis pendant les manipulations et éviter ainsi de détériorer la surface des panneaux I1, I2. On coule ensuite la dalle de béton sur l'ensemble. La fonction des éléments d'ancrage E1, E1', E2, E2' est de permettre une liaison solide entre le béton et les panneaux I1 et I2.To complete the construction of the concrete wall, a metal mesh T is then placed on unrepresented shims, advantageously made of plastics material, which can be integral with the anchoring elements E1, E1 ', E2, E2'. as described in FR 2 624 154 A , or independent thereof, these shims resting on the panels I1 and I2 and now the lattice spaced apart from the anchoring elements and at a distance of about 3 cm from the surface of the panels. These wedges are preferably of great length to distribute the weight of people who circulate on the mesh during handling and thus avoid damaging the surface of the panels I1, I2. Then pour the concrete slab on the whole. The function of the anchoring elements E1, E1 ', E2, E2' is to allow a solid connection between the concrete and the panels I1 and I2.

On peut voir en figure 3 la structure obtenue en coupe, après coulée du béton B, dans le cas de la réalisation d'un plancher isolant.We can see in Figure 3 the structure obtained in section, after casting concrete B, in the case of the realization of an insulating floor.

De même que le coffrage de plancher classique selon EP 0 427 596 , le coffrage métallique selon l'invention repose avant coulée du béton sur des appuis tels que des étais qui seront retirés après durcissement, le coffrage étant alors suspendu à la dalle de béton grâce aux éléments d'ancrage. Toutefois, l'invention permet de réduire le nombre de ces étais, conduisant à une économie supplémentaire. Il suffit ainsi de disposer 3 étais entre deux poutres du plancher distantes de 6 mètres, alors que 6 à 10 étais doivent être alignés sur la même distance dans la technique existante. Le nombre d'étais est encore diminué, soit 1 étai pour un écartement de 6 mètres, lorsque les deux extrémités de chaque profilé s'appuient respectivement sur deux poutres voisines, soit directement, soit indirectement par exemple par l'intermédiaire de cornières fixées aux poutres.As well as the classic floor formwork according to EP 0 427 596 , the metal formwork according to the invention rests before pouring concrete on supports such as props that will be removed after hardening, the formwork then being suspended from the concrete slab through the anchoring elements. However, the invention makes it possible to reduce the number of these struts, leading to an additional saving. It suffices to have 3 stays between two beams of the floor 6 meters apart, while 6 to 10 struts must be aligned at the same distance in the existing technique. The number of struts is further decreased, 1 strut for one spacing of 6 meters, when the two ends of each section respectively rely on two adjacent beams, either directly or indirectly, for example by means of brackets fixed to the beams.

Il est possible si nécessaire de renforcer la liaison entre le béton et les profilés du coffrage selon l'invention en fixant sur ces profilés, par exemple par vissage, des tirants métalliques faisant saillie au-delà des panneaux isolants et noyés dans le béton sur une partie de l'épaisseur de celui-ci, sans affecter de manière notable l'isolation thermique.It is possible, if necessary, to reinforce the connection between the concrete and the sections of the formwork according to the invention by fastening on these sections, for example by screwing, metal tie rods protruding beyond the insulating panels and embedded in the concrete on a surface. part of the thickness thereof, without significantly affecting the thermal insulation.
