DALLE ISOLANTE
Les bâtiments d'habitation ou de bureau sont aujourd'hui soumis a des normes d'isolement thermique sévéres. De plus, particulièrement pour les maisons individueZZes, les entreprises de construction demandent à utiliser des éléments dits manuportables, c'est-à-dire manutentionnables à la main. Enfin, iZ existe des normes concernant la surcharge que doit pouvoir supporter chaque métre carré de pZancher.INSULATING SLAB
Residential and office buildings are today subject to strict thermal insulation standards. In addition, particularly for individual houses, construction companies require the use of elements that are said to be portable, that is to say, which can be handled by hand. Finally, iZ exists standards concerning the overload that must be able to support each square meter of pZancher.
La présente innovation concerne une daZZe isoZante, formée d'éléments manuportables, en forme de poutres pZates sur
ZesqueZZes est couZée la daZZe. La résistance à la surcharge apparaît en deux étapes.The present innovation relates to an isoZante daZZe, formed of movable elements, in the form of pZates beams on
ZesqueZZes is laid down the daZZe. Overload resistance occurs in two stages.
. Au moment où les poutres plates sont juxtaposées, eZZes
forment un plancher qui peut supporter le poids d'un homme
et Ze poids de la chappe de béton qui doit être coulée,
sur toute la surface qui constituera la daZZe isoZante. Les
poutres plates juxtaposées forment ainsi un coffrage perdu.. When the flat beams are juxtaposed, eZZes
form a floor that can support the weight of a man
and Ze weight of the concrete screed to be poured,
over the entire surface which will constitute the isoZante daZZe. The
juxtaposed flat beams thus form a lost formwork.
. Une fois que la chappe de béton a durci, eZZe coopére avec
les poutres pZates pour former un ensemble capable de
supporter les surcharges normalisées.. Once the concrete screed has hardened, eZZe cooperates with
pZates beams to form an assembly capable of
withstand normalized overloads.
Les poutres plates sont formées d'une tôZe pliée, teZZe qu'indiquée en 3 sur la figure 1. La forme en double U Zui donne une rigidité qui Zui permet de supporter Ze poids de la dalle en béton, qui sera coulée en 1 sur la figure 1.The flat beams are formed from a folded sheet, teZZe as indicated in 3 in FIG. 1. The shape in double U Zui gives a rigidity which Zui allows to support Ze weight of the concrete slab, which will be poured in 1 on Figure 1.
L'intérieur du profiZ de la tôZe est rempli d'un bloc de mousse telle que le polystyréne, qui assure deux fonctions : . d'une part, eZZe donne à l'ensemble la capacité d'isolation
requise par les normes, . d'autre part, étant collé sur la tôle 3, elle évite le
flambement de celle-ci sous les efforts dûs au poids de la
chappe, puis, ultérieurement, de la surcharge normaZisée.The inside of the sheet profiZ is filled with a block of foam such as polystyrene, which performs two functions:. on the one hand, eZZe gives the assembly the insulation capacity
required by standards,. on the other hand, being glued to the sheet 3, it avoids the
buckling of the latter under the forces due to the weight of the
chappe, then, later, of the normalized overload.
Une fois la chappe coulée, les efforts de compression sont encaissés par la chappe, et les efforts de traction par la tôZe. Pour que ces deux éléments puissent coopérer, ils doivent être Ziés par un élément qui transmet les efforts tranchants dus au poids de la surcharge. Les flancs verticaux de la tôle, dont le bord supérieur est noyé,dans la chappe, effectuent
cette transmission. Once the chappe has been poured, the compressive forces are collected by the chappe, and the tensile forces by the sheet. In order for these two elements to cooperate, they must be Zied by an element which transmits the cutting forces due to the weight of the overload. The vertical sides of the sheet, whose upper edge is embedded, in the chappe, carry out
this transmission.
Ce flanc de tôZe présente Z'inconvénient de transmettre la chaleur entre la chappe de béton et la surface inférieure des poutres pZates. Sauf précaution spéciale, cette transmission ne permet pas de tenir les normes d'isolation thermique. This sheet metal side has the drawback of transmitting heat between the concrete screed and the lower surface of the pZate beams. Unless special precautions are taken, this transmission does not meet thermal insulation standards.
Pour atteindre ces normes d'isolation, Ze flanc est percé de trous indiqués en 5 sur la figure 1. L'intervaZZe 6 entre ces trous doit être trés Zimité, la Zargeur des intervalles étant de l'ordre de 5 % de la largeur des trous.To reach these insulation standards, the flank is pierced with holes indicated at 5 in FIG. 1. The intervaZZe 6 between these holes must be very limited, the width of the intervals being of the order of 5% of the width of the holes.
Des intervalles aussi réduits mettraient en cause la bonne transmission des efforts tranchants entre la chappe de béton et la tôZe inférieure, si une précaution particulière n'était pas prise : la partie la pZus réduite de l'intervalle est placée à l'endroit de la fibre neutre de Z'ensembie formé par la chappe de béton et la tôZe. Lorsque Z'on s'écarte de la fibre neutre,
Z'intervaZZe s'élargit, de façon à ce que la quantité de métaZ présente soit toujours suffisante pour encaisser les efforts tranchants.Such reduced intervals would jeopardize the good transmission of the shear forces between the concrete screed and the lower sheet, if no particular precaution was taken: the smallest part of the interval is placed at the location of the neutral Z'ensembie fiber formed by the concrete screed and the sheet. When we move away from the neutral fiber,
Z'intervaZZe widens, so that the quantity of metaZ present is always sufficient to absorb the shearing forces.
Un dimentionnement indicatif consiste à donner aux poutres plates une Zargeur de 60 cm dans la partie haute, et 30 cm dans la partie inférieure, une épaisseur de 10 cm sur les aiZes Latérites et de 20 cm au centre. La tôle peut avoir 0,7 mm d'épaisseur et être pliée et découpée en continu. La chappe de béton peut présenter une épaisseur de 5 cm. Dans ces conditions, la fibre neutre de l'ensemble se trouve à 0,6 cm saus Ze béton.An indicative dimensioning consists in giving the flat beams a width of 60 cm in the upper part, and 30 cm in the lower part, a thickness of 10 cm on the laterites and 20 cm in the center. The sheet can be 0.7 mm thick and can be bent and cut continuously. The concrete screed may have a thickness of 5 cm. Under these conditions, the neutral fiber of the assembly is 0.6 cm apart from concrete.
Les trous 5 sont en forme de demi ellipse, avec une partie dans la chappe de béton, de façon à ce que Ze béton qui s engage dans la partie supérieure 4 de ces trous fournisse un bon ancrage de la tôZe dans Ze béton.The holes 5 are in the form of a half ellipse, with a part in the concrete screed, so that Ze concrete which engages in the upper part 4 of these holes provides good anchoring of the sheet in Ze concrete.
Le prix de ces poutr-es doit rester très faible. Dans ce but iZ est opportun de constituer le bloc de mousse indiqué en 2 sur la figure 1 par découpage d'un grand bZoc, qui, dans l'état actueZ de l'art, a généralement les dimensions 1,2 m X 0,5 m X 5 métrez. Les formes d'imbrication indiquées sur la figure 2 permettent d'obtenir le bloc de mousse par découpage d'un grand bloc sans chute. The price of these beams must remain very low. For this purpose iZ is appropriate to constitute the foam block indicated at 2 in FIG. 1 by cutting out a large bZoc, which, in the state of the art, generally has the dimensions 1.2 m X 0, 5 m X 5 meter. The nesting forms shown in Figure 2 allow to obtain the foam block by cutting a large block without falling.
