Description

.Panneau composite pour le recouvrement d'une surface plane et procédé pour sa fabrication . Composite panel for covering a flat surface and method for its manufacture
Dans la demande de brevet suisse No.251/81 on décrit un panneau de recouvrement d'une surface plane, prévu principalement- pour recouvrir un toit plat. -Ce pan¬ neau comporte une plaque en ciment ou en béton armé par des fibres, des filaments, et/ou une armature rigide, et une plaque en un isolant rigide à structure cellulaire, les deux plaques étant imbriquées l'une dans l'autre. Bien que présentant d'importants avantages, ce panneau peut encore être amélioré pour mieux résister aux charges statiques et minimiser les conséquences des dilatations thermiques dues aux changements άe température. En effet, à cause des coefficients d'expansion thermique sensible¬ ment différents du ciment ou béton d'une part, et du matériau isolant de l'autre, les variations importantes t répétées de température auxquelles est soumis un toit conduisent dans les plaques intine ent liées à des tensions telles, que l'isolant se rompt d' abord en cer¬ tains endroits, puis s'effrite peu à peu par brisures successives réparties- dans tout son intérieur, et ceci en un temps relativement court. Pour éviter ces inconvénients, le panneau selon la présente invention et son procédé de fabrication sont définis comme il est dit aux revendications.In the Swiss patent application No. 251/81 a panel covering a flat surface is described, mainly intended to cover a flat roof. -This panel comprises a cement or reinforced concrete plate with fibers, filaments, and / or a rigid reinforcement, and a plate made of a rigid insulator with cellular structure, the two plates being nested one in the other. Although having significant advantages, this panel can be further improved to better resist static loads and minimize the consequences of thermal expansion due to temperature changes. In fact, because of the significantly different thermal expansion coefficients of the cement or concrete on the one hand, and of the insulating material on the other, the large repeated temperature variations t to which a roof is subjected lead to the intestinal plates. ent linked to tensions such that the insulator breaks first in certain places, then crumbles gradually by successive breaks distributed throughout its interior, and this in a relatively short time. To avoid these drawbacks, the panel according to the present invention and its manufacturing process are defined as stated in the claims.
Cette solution permet de limiter les contraintes auxquelles sont vsoumis à la fois le ciment ou béton, l'isolant et la liaison entre les deux. Une forme d'exécu¬ tion' consiste à déterminer dans l'isolant les lignes de. rupture en prévoyant sur la face du béton tournée vers l'isolant des nervures dont au moins certaines sont assez profondes pour amorcer une rupture préférentielle face à ces nervures. Celles-ci améliorent en même temps la cohésion entre la couche d'isolant et celle en ciment ou béton, ainsi que la résistance statique de cette dernière, qui forme ainsi un plafond à caisson, noyé dans l'isolant rigide. Cela permet de réduire sensible¬ ment l'épaisseur de la plaque portante en ciment ou béton pour une charge donnée, d'où économie de poids et de matériau. De façon moins évidente à priori, cette forme d'exécution résout dans une large mesure les problèmes dus aux variations de température en formant des zones de rupture prédéterminées de l'isolant, au droit des ' nervures. Celles-ci forment en même temps des imbrica¬ tions favorisant la liaison des plaques, qui peuvent ainsi être fixées réciproquement sans utiliser d'adhésif. Etant donné que les adhésifs usuels contiennent en général des produits comme le latex ou le bitume qui sont imperméables à la vapeur d'eau, il peut être avantageux pour certaines applications (comme les toits dits "inversés") de ne pas utiliser de couches adhesives afin de faciliter le passage de l'humidité. . .This solution makes it possible to limit the stresses to which v the cement or concrete, the insulation and the connection between the two are subjected. One form of exécu¬ tion 'includes determining the insulation lines. rupture by providing on the face of the concrete facing the insulation of the ribs, at least some of which are deep enough to initiate a preferential rupture in the face of these ribs. These at the same time improve the cohesion between the insulation layer and that of cement or concrete, as well as the static resistance of the latter, which thus forms a box ceiling, embedded in the rigid insulation. This allows the thickness of the cement or concrete bearing plate to be reduced significantly for a given load, thereby saving weight and material. In a less obvious way a priori, this embodiment largely solves the problems due to temperature variations by forming predetermined rupture zones of the insulation, in line with the 'ribs. These form at the same time imbrica¬ tions promoting the bonding of the plates, which can thus be fixed reciprocally without using adhesive. Since the usual adhesives generally contain products such as latex or bitumen which are impermeable to water vapor, it may be advantageous for certain applications (such as so-called "inverted" roofs) not to use adhesive layers to facilitate the passage of moisture. . .
Une variante consiste à terminer les nervures par un dièdre ayant de préférence un angle d'ouverture aigu, dont 1'arête vive provoque une amorce de rupture dans l'isolant. Il est également possible d'amorcer les lignes de rupture par des coupures - de préférence en forme de pointillé - dans l'isolant et face aux nervures, si celles- ci sont également prévues.A variant consists in terminating the ribs with a dihedral preferably having an acute opening angle, the sharp edge of which causes a breakthrough in the insulation. It is also possible to prime the lines rupture by cuts - preferably in the form of a dotted line - in the insulation and facing the ribs, if these are also provided.
Dans le panneau selon l'invention, les lignes de rupture prédéterminées de l'isolant réduisent sa tendance à se fissurer ailleurs, même après de nombreux cycles de température, ce qui évite l'effritement progressif bien connu et très dommageable de l'isolant des panneaux précédemment"connus. L'invention sera maintenant illustrée par une brève description de quelques variantes de réalisation et à l'aide du dessin, dans lequel la fig. 1 représente une section partielle d'un toit recouvert, la fig. 2 représente une vue en perspective de la partie portante d'un panneau composite, avant sa réunion avec la couche isolante, et la fig. 3 représente différents profils de nervu¬ res. Dans la coupe de la fig. 1 le chiffre 1 désigne la plaque en béton formant la surface à recouvrir, qui ici représente un toit. Celui-ci est recouvert d'une couche imperméable 2 en un composé de bitume _et de latex, produit largement commercialisé. Outre son imperméabilité, cette couche présente la particularité d'être suffisam¬ ment souple pour compenser les inégalités toujours présen¬ tes de la surface à recouvrir. De plus, la couche impermé¬ able 2 est auto-collante, et immobilise ainsi une couche de matériau isolant 4, qui lui est superposée, par rapport au toit 1. La couche thermiquement isolante 4 est formée par des plaques d'un isolant à structure cellulaire fermée ou ouverte, qui peut être du polystyrène extrudé ou expansé par exemple, ou un matériau similaire. Au-dessus de l'isolant 4 se trouve une couche de ciment compacté 5, renforcé par des fils 6 en matière organique ou autre, qui peuvent être soit formés de fibres torsadées soit de filaments monotoron, les fils eux-mêmes étant frisés ou non. Ils peuvent être, entre autre, en polypropylène, en polyester, en " e lar", etc Alternativement ou de façon supplémentaire, le ciment peut être renforcé par une armature rigide 7, soit métallique soit en l'un des matériaux précédents (représentée en points-tirets) , et qui s'étendra de préférence jusqu'à l'intérieur de nervu¬ res 8 fixant mécaniquement la couche de ciment 5 à l'iso¬ lant 4. Pour améliorer encore cette fixation, une exécu¬ tion préférée prévoit un armement du panneau par des barres d'ancrage rigides noyées^partiellement dans le ciment, et partiellement dans l'isolant. Ces barres d'ancrage peuvent être constituées par les barres d'arme- ment usuelles du ciment ou béton, qui dépasseron 'de celui-ci sur sa face tournée vers l'isolant. Dans la fig.l, une barre d'ancrage 10 joint différentes nervures 8,9 à travers l'isolant 4, mais bien d'autres formes de barres d'armement communes aux deux plaques sont évidemment possibles.In the panel according to the invention, the predetermined breaking lines of the insulation reduce its tendency to crack elsewhere, even after numerous temperature cycles, which prevents the well-known and very damaging progressive erosion of the insulation of the panels previously "known. the invention will now be illustrated by a brief description of a few embodiments and the drawing, wherein fig. 1 shows a partial section of a roof covered, fig. 2 shows a perspective view of the bearing part of a composite panel, before it meets the insulating layer, and Fig. 3 represents different profiles of ribs In the section of Fig. 1 the number 1 designates the concrete plate forming the surface to be covered, which here represents a roof, which is covered with an impermeable layer 2 of a compound of bitumen and latex, a product that is widely marketed. he has the particularity of being sufficiently flexible to compensate for the inequalities still present in the surface to be covered. In addition, the waterproof layer 2 is self-adhesive, and thus immobilizes a layer of insulating material 4, which is superimposed on it, relative to the roof 1. The thermally insulating layer 4 is formed by plates of an insulator with closed or open cell structure, which can be extruded or expanded polystyrene for example, or a similar material. Above the insulation 4 is a layer of compacted cement 5, reinforced by threads 6 of organic or other material, which can be either formed of twisted fibers or of single-strand filaments, the threads themselves being crimped or not . They can be, among other things, polypropylene, polyester, "e lar", etc. Alternatively or additionally, the cement can be reinforced by a rigid reinforcement 7, either metallic or one of the preceding materials (shown in dots), and which will preferably extend to the interior of ribs 8 resetting mechanically the cement layer 5 to the insulation 4. To further improve this fixing, a preferred embodiment provides a cocking of the panel by rigid anchor bars embedded ^ partly in cement, and partly in the insulation. These anchoring bars can be constituted by the usual ment armaments bars cement or concrete which dépasseron 'thereof on its side facing the insulator. In fig.l, an anchor bar 10 joins different ribs 8, 9 through the insulation 4, but many other forms of armament bars common to the two plates are obviously possible.
La profondeur des nervures 8 est suffisante pour" déterminer à leur aplomb des zones Z de rupture préféren¬ tielles de l'isolant. Un choix judicieux de l'espacement de ces nervures, dites ici "nervures longues" permet de prévenir la formation de fissures en d'autres endroits, même après des cycles de température répétés et avec des coefficients de dilatation thermique très différents pour le ciment et le matériau isolant à structure cellulaire. Si les charges statiques l'exigent, on pourra prévoir d'autres nervures 11, dites "nervures courtes", d'une hau¬ teur inférieure et qui de ce fait renforcent le panneau sans déterminer de zones de ruptures équivalentes à cellesThe depth of the ribs 8 is sufficient to "determine at their height zones Z of preferential rupture of the insulation. A judicious choice of the spacing of these ribs, here called" long ribs "makes it possible to prevent the formation of cracks in other places, even after repeated temperature cycles and with very different coefficients of thermal expansion for the cement and the insulating material with cellular structure. If the static loads require it, other ribs may be provided 11, called "short ribs", of a lower height and which therefore reinforce the panel without determining break zones equivalent to those

des nervures longues. Il est évidemment avantageux de pré¬ voir deux groupes (8a,8b) de nervures orthogonales les unes aux autres, de manière que la couche en ciment forme un plafond à caissons comme il est montré en perspective à la fig. 2. Ce plafond est noyé dans l'isolant, et il est loisible à la fabrication d'utiliser l'une ou l'autre de • ces couches comme un moule perdu pour y couler, respective¬ ment pour y expanser l'autre. A cet effet il peut être avantageux de prévoir des nervures extérieures 9 plus grandes que les autres, ou plus exactement de même profon¬ deur que la couche isolante ainsi qu'il est montré à la figure 1 mais non à la figure 2.long ribs. It is obviously advantageous to pre¬ see two groups (8a, 8b) of ribs orthogonal to each other, so that the cement layer forms a coffered ceiling as shown in perspective in FIG. 2. This ceiling is embedded in the insulation, and it is permissible during manufacture to use one or the other of these • layers as a lost mold to flow therein, respectively to expand the other therein. To this end, it may be advantageous to provide external ribs 9 which are larger than the others, or more exactly the same depth as the insulating layer, as shown in FIG. 1 but not in FIG. 2.
La figure 3 montre un choix de quelques profils utilisables pour déterminer des lignes de ruptures, en sus de la nervure longue 8 déjà décrite à la figure 2. Evidem¬ ment ces différents profils, montrés ici dans une seule figure, ne seront "pas nécessairement utilisés simultané- • ment dans un même panneau. Les nervures 14 et 15 ont un profil en escalier dont la largeur diminue vers leur • - extrémité, ce qui permet de former des profils relative¬ ment hauts, avec un poids de ciment réduit. Les profils 16 et 17 se terminent en un dièdre à angle aigu qui induit une amorce de rupture même lorsque la nervure ne s'enfonce pas très profondément dans l'isolant. La rupture peut égale ment être amorcée par une coupure 18 dans l'isolant, pratiquée face à une nervure et -fOr ant par exemple un pointillé dans la direction normale au dessin.FIG. 3 shows a choice of a few profiles which can be used to determine break lines, in addition to the long rib 8 already described in FIG. 2. Obviously, these different profiles, shown here in a single figure, will not necessarily be " used simultaneously • in the same panel. The ribs 14 and 15 have a stepped profile whose width decreases towards their • - end, which makes it possible to form relatively high profiles, with a reduced weight of cement. profiles 16 and 17 terminate in an acute angle dihedral which induces a rupture initiation even when the rib does not sink very deeply into the insulation. The rupture can also be initiated by a cut 18 in the insulation, practiced in front of a rib and -For for example a dotted line in the direction normal to the drawing.
La référence 20, finalement, indique une position préférée pour des barres rigides d'armement, à proximité du bord libre des nervures longues, et parallèlement à celui-ci.Finally, the reference 20 indicates a preferred position for rigid cocking bars, close to and parallel to the free edge of the long ribs.
