Description
Plaque ondulée utilisable dans la construction
La présente invention concerne une plaque ondulée utilisable dans la construction.Corrugated plate usable in construction
The present invention relates to a corrugated plate usable in construction.
Les plaques actuellement utilisées dans la construction sont de type renforcé au moyen de fibres de matériau dispersées dans le mortier matriciel. Le matériau desdites fibres est sélectionné parmi un ou plusieurs des éléments suivants: la cellulose, le polyéthylène, le polyacrylonitrile, le polyvinylalcool. The plates currently used in construction are of the reinforced type by means of material fibers dispersed in the matrix mortar. The material of said fibers is selected from one or more of the following: cellulose, polyethylene, polyacrylonitrile, polyvinyl alcohol.
De telles fibres sont utilisées de préférence à des fibres d'amiante plus classiques, qui, cependant, d'après l'expérience, se sont révélées nuisibles et donc défendues, malgré les caractéristiques de résistance mécanique élevée conférées par l'amiante auxdites plaques, leur coût modéré et leur facilité d'utilisation. Such fibers are used in preference to more conventional asbestos fibers, which, however, according to experience, have proved to be harmful and therefore defended, despite the characteristics of high mechanical strength conferred by asbestos on said plates, their moderate cost and ease of use.
C'est pourquoi il se pose le problème de réaliser des plaques qui, sans être nuisibles, présentent toutefois des caractéristiques de résistances et de coût analogues à celles des fibres en amiante. This is why the problem arises of producing plates which, without being harmful, nevertheless have characteristics of resistance and cost similar to those of asbestos fibers.
Pour des raisons économiques, les utilisateurs tendent à exploiter le plus possible les caractéristiques de résistance des plaques, en écartant le plus possible les appuis sur lesquels sont posés les plaques. For economic reasons, users tend to exploit the strength characteristics of the plates as much as possible, by avoiding as much support as possible on which the plates are placed.
C'est pourquoi, pour une raison quelconque, lorsqu'une plaque est plus fragile que les autres ou lorsque les sollicitations accidentelles sont trop élevées, une rupture imprévue peut apparaître, qui, dans certains cas, peut provoquer de sérieux problèmes. This is why, for some reason, when one plate is more fragile than the others or when the accidental stresses are too high, an unforeseen rupture can appear, which, in certain cases, can cause serious problems.
Le but de la présente invention est de surmonter l'inconvénient de la moindre résistance, ainsi que celui de la fragilité, de manière économiquement avantageuse, et donc de réaliser une plaque en ciment renforcé qui offre des caractéristiques mécaniques et de garantie, du point de vue de l'empêchement des accidents du travail, à des coûts relativement réduits. The object of the present invention is to overcome the disadvantage of lower resistance, as well as that of brittleness, economically advantageously, and therefore to produce a reinforced cement plate which offers mechanical and guarantee characteristics, from the point of in view of the prevention of accidents at work, at relatively reduced costs.
Ces buts sont atteints par une plaque selon la revendication 1. These objects are achieved by a plate according to claim 1.
La plaque ondulée utilisable dans la construction, du type renforcé au moyen de fibres, permet d'obtenir le meilleur compromis de résistance et d'économie, en particulier pour la combinaison particulière des éléments qui la composent. The corrugated plate usable in construction, of the type reinforced with fibers, makes it possible to obtain the best compromise of resistance and economy, in particular for the particular combination of the elements which compose it.
L'invention est illustrée à titre d'exemple uniquement, mais non-limitatif, sur les tables de dessins annexées. The invention is illustrated by way of example only, but not limitation, on the accompanying drawing tables.
La figure 1 est une vue en coupe d'une plaque de
l'invention, selon une première forme de
réalisation; la figure 2 est une vue en coupe d'une plaque de
l'invention, selon une deuxième forme de
réalisation; la figure 3 est une vue en perpective d'une plaque de
l'invention, selon une troisième forme de
réalisation.Figure 1 is a sectional view of a plate of
the invention, according to a first form of
production; Figure 2 is a sectional view of a plate
the invention, according to a second form of
production; Figure 3 is a perspective view of a plate of
the invention, according to a third form of
production.
En se référant aux figures précitées, en particulier à la figure 1, la plaque selon l'invention, généralement désignée par le numéro de préférence 1, est de type ondulé et présente, au moins en correspondance des pointes 2 destinées à être tournées vers le bas, un ruban 3 ou bande ou support rectiligne, disposé dans la direction longitudinale de la plaque. Referring to the aforementioned figures, in particular to Figure 1, the plate according to the invention, generally designated by the number of preference 1, is of wavy type and has, at least in correspondence with the points 2 intended to be turned towards the bottom, a ribbon 3 or strip or rectilinear support, arranged in the longitudinal direction of the plate.
Cette bande est de préférence réalisée en matériau synthétique. This strip is preferably made of synthetic material.
Des fibres constituées des matériaux qui suivent et présents selon les quantités qui suivent, exprimées en pourcentage, sont disposées dans le mortier matriciel: - fibres de cellulose ou de polyéthylène: 1 à 5 %, - fibres de polyacrylonitrile ou de polyvinylalcool: 1 à 6 t. Fibers made up of the following materials and present in the following quantities, expressed as a percentage, are placed in the matrix mortar: - cellulose or polyethylene fibers: 1 to 5%, - polyacrylonitrile or polyvinyl alcohol fibers: 1 to 6 t.
Les pourcentages de ciment inertes et d'éventuels additifs sont ceux qui sont usuellement prévus pour les mortiers matriciels des plaques connues. The percentages of inert cement and of possible additives are those which are usually provided for matrix mortars of known plates.
A titre indicatif, la plaque selon la figure 1 présente un pas "p" doté d'une valeur comprise entre 177 et 146 mm, une amplitude "a" comprise entre 51 et 48 mm et une épaisseur "S" comprise entre 6 et 7 mm. As an indication, the plate according to Figure 1 has a pitch "p" with a value between 177 and 146 mm, an amplitude "a" between 51 and 48 mm and a thickness "S" between 6 and 7 mm.
Les plaques illustrées sur les figures 1 et 2 peuvent toutes deux être réalisées de manière incurvée ou bien incurvée dans la direction perpendiculaire à l'axe des ondulations. The plates illustrated in FIGS. 1 and 2 can both be produced in a curved manner or else curved in the direction perpendicular to the axis of the corrugations.
L'une de ces plaques est précisément une plaque présentant des sections identiques à celle illustrée sur la figure 1 et est illustrée sur la figure 2, dans laquelle elle est désignée par le numéro de référence 1B. One of these plates is precisely a plate having sections identical to that illustrated in FIG. 1 and is illustrated in FIG. 2, in which it is designated by the reference number 1B.
Le rayon d'incurvation présente une valeur comprise de façon indicative entre 2,5 et 20 m, en vue de satisfaire aux exigences constructives communes. The radius of curvature has an indicative value between 2.5 and 20 m, in order to satisfy common construction requirements.
Etant donné que ces plaques sont incurvées après la fabrication et avant d'avoir réalisé le durcissement complet, leur résistance subit une diminution, qui est cependant rendue pour le moins sans conséquence par les rubans 3B. Since these plates are curved after manufacture and before having achieved complete hardening, their resistance undergoes a decrease, which is however rendered at the very least without consequence by the ribbons 3B.
La présence des rubans 3B permet aux plaques d'être ainsi mises en fonctionnement avec des lumières entre les appuis, par rapport aux plaques rectilignes, ce qui donne lieu à des avantages lors de l'utilisation. The presence of 3B ribbons allows the plates to be thus operated with lights between the supports, relative to the rectilinear plates, which gives rise to advantages during use.
Dans tous les cas cités, les bandes ou rubans 3 à 3B sont constitués de polypropylène et, pour augmenter la prise par rapport au mortier matriciel, comprennent une surface rugueuse ou, par unité de longueur, des trous traversants dans le sens de l'épaisseur. In all the cases mentioned, the strips or tapes 3 to 3B are made of polypropylene and, to increase the setting with respect to the matrix mortar, include a rough surface or, per unit of length, through holes in the thickness direction .
D'autres formes de réalisation des plaques 1 à 1B peuvent proposer de remplacer les rubans 3 à 3B par des films constitués de fils d'acier, ou bien constitués de fibres ou de filaments de carbone étirés, ou bien de verre résistant aux bases. Other embodiments of the plates 1 to 1B can propose replacing the ribbons 3 to 3B by films made of steel wires, or else made of drawn carbon fibers or filaments, or else of glass resistant to the bases.
Les caractéristiques mécaniques de ces fils, c'est-àdire la résistance à la traction et le module élastique, sont analogues à celles de l'acier. The mechanical characteristics of these wires, that is to say the tensile strength and the elastic modulus, are similar to those of steel.
Cependant, parmi tous les fils précités, les fils constitués de fibres ou de filaments de carbone étirés sont en réalité plus appropriés. However, among all the abovementioned yarns, yarns made up of drawn carbon fibers or filaments are actually more suitable.
Les fils sont prévus en un nombre et avec un diamètre tels que leur section resistance complexe égale au moins la résistance du ruban. The wires are provided in a number and with a diameter such that their complex resistance section equals at least the resistance of the ribbon.
