Abstract

The insulating floor joist is made from two insulating halves (2) fixed with adhesive to either side of a central supporting member (1) which can be of concrete, metal profile or folded strip, or natural or reconstituted timber. The insulating halves have tongues (4) which meet beneath the supporting member and are joined by a connector (5), and they are fitted to the supporting member by the application of pressure from both sides.

Description

Le domaine de 11 invention est celui des planchers nervurés en béton comportant des entrevous en matériaux légers servant de coffrages perdus,mais dont l'utilité est surtout d'augmenter fortement la résistance thermique de ces ouvrages,destinés en majorité à l'habitation.The field of the invention is that of ribbed concrete floors comprising interjoists made of light materials serving as lost formwork, but the utility of which is above all to greatly increase the thermal resistance of these works, intended mainly for housing.

La présente invention a pour résultat de perfectionner le proçédé de fabrication des solives isolantes autoporteuses décrites par le Brevet français 84I9570.Cette fabrication s'effectue actuellement de la manière suivante
Après avoir disposé une armature appropriée dans l'évidement central filant de la solive isolante reposant sur un plan de travail horizontal, on remplit cet évidement avec un béton fin de consistance très plastique;après la prise de ce béton, la solive isolante,parcequ'elle adhère au béton armé,est devenue autoporteuse et constitue alors un élément de construction fini,transportable et prêt à être mis en oeuvre avec les entrevous isolants qui complètent ce système de plancher.The present invention results in perfecting the process for manufacturing self-supporting insulating joists described by French Patent 84I9570. This manufacturing is currently carried out as follows
After having arranged an appropriate reinforcement in the central recess threading the insulating joist resting on a horizontal work plan, we fill this recess with a fine concrete of very plastic consistency; after the setting of this concrete, the insulating joist, because it adheres to reinforced concrete, has become self-supporting and then constitutes a finished construction element, transportable and ready to be used with the insulating interjoists which complete this floor system.

Ce proçédé de fabrication qui vient d'être sommairement décrit présente cependant quelques inconvénients
Premièrement, de néçessiter une main d'oeuvre spéçialisée et de qualité,le remplissage de l'évidement central filant comme la mise en place correcte du béton étant difiçilement mécanisables,compte tenu des relativement faibles volumes à traiter, et de la gêne occasionnée par la présence des armatures transversales.This manufacturing process which has just been briefly described, however, has some drawbacks
First, to require a specialized and quality workforce, the filling of the spinning central recess as the correct placement of the concrete being difficult to mechanize, taking into account the relatively small volumes to be treated, and the discomfort caused by the presence of transverse reinforcement.

Ensuite,à moins de disposer d'une installation de traitement thermique du béton, ou d'un stock permanent de solives fabriquées à l'avance,leur délai de livraison est d'environ une semaine,dans des conditions climatiques favorables.Then, unless you have a heat treatment facility for concrete, or a permanent stock of joists made in advance, their delivery time is around a week, in favorable weather conditions.

Ces inconvénients,auxquels la présente invention permet de remèdier, constituent une entrave au développement de ce système de plancher isolant issu du Brevet déja çité.Le perfectionnement apporté par la présente invention consiste à simplifier avantageusement la fabrication des solives isolantes autoporteuses en la réduisant à un assemblage collé de composants industriels finis. Cet assemblage collé solidarise en effet les deux composants de la solive isolante autoporteuse, soit
D'une part,le composant porteur,qui est de préférence une poutrelle préfabriquée en béton au profil en forme de T renversé comportant une armature pour béton armé ou pour béton précontraint,ou encore une combinaison de ces techniques.These drawbacks, to which the present invention makes it possible to remedy, constitute an obstacle to the development of this insulating floor system resulting from the already patented. The improvement brought by the present invention consists in advantageously simplifying the manufacture of the self-supporting insulating joists by reducing it to a bonded assembly of finished industrial components. This bonded assembly indeed secures the two components of the self-supporting insulating joist, i.e.
On the one hand, the load-bearing component, which is preferably a prefabricated concrete beam with an inverted T-shaped profile comprising a reinforcement for reinforced concrete or for prestressed concrete, or a combination of these techniques.

D'autre part,le composant isolant,qui est la solive à profil trapèzoidal décrite par le Brevet français 8419570,solive qui est,de façon nouvelle et selon l'invention,partagée dans sa longueur en deux parties,de préférence par son axe vertical de symétrie pour former ainsi deux demi-solives isolantes,droites et gauches; à leur base,ces demi-solives isolantes peuvent présenter un dispositif d'assemblage et de liaison de préférence à tenon et mortaise. Sans sortir du cadre de la présente invention,ce composant porteur peut être réalisé en métal ou en bois naturel ou reconstitué, ces matériaux étant utilisés séparément ou ensemble. On the other hand, the insulating component, which is the joist with trapezoidal profile described by French patent 8419570, joist which is, in a new way and according to the invention, divided in its length into two parts, preferably by its vertical axis. of symmetry to thus form two insulating half-joists, right and left; at their base, these insulating half-joists may have an assembly and connection device, preferably with a tenon and mortise. Without departing from the scope of the present invention, this supporting component can be made of metal or natural or reconstituted wood, these materials being used separately or together.

Selon un mode préférentiel de réalisation de 1' invention,l1 assemblage et la solidarisation des composants isolants et porteurs s'effectue ainsi
La première opération consiste à enduire de colle,par un moyen apnroprié,toutes les parties devant être solidarisées.According to a preferred embodiment of the invention, the assembly and joining of the insulating and supporting components is thus carried out
The first operation consists in coating with glue, by an appropriate means, all the parts to be joined.

La seconde consiste à plaçer,de préférence à l'horizontale le composant porteur sur deux appuis d'extrèmités situés à un niveau un peu supérieur à celui du plan de travail,qui lui est parallèle;sur ce même plan de travail sont disposées longitudinalement et de chaque côté du composant porteur,qu'elles encadrent,une demisolive isolante droite et une demi-solive isolante gauche.The second consists in placing, preferably horizontally, the carrier component on two end supports located at a level slightly higher than that of the work surface, which is parallel to it; on this same work surface are arranged longitudinally and on each side of the load-bearing component, which they frame, a right insulating half-joist and a left insulating half-joist.

La troisième et dernière opération consiste à exerçer une poussée,de préférence mécanique ,horizontale et bi-latérale sur les demi-solives isolantes, poussée qui aura pour effet de les rapprocher du composant porteur,en les faisant glisser sur le plan de travail, jusqu'à une énergique mise en contact de toutes les parties, préalablement enduites de colle. La pression ayant obtenu 1' assemblage des composants sera maintenue par un dispositif de serrage approprié durant le temps néçe ssaire à la prise de la colle utilisée.The third and last operation consists in exerting a push, preferably mechanical, horizontal and bi-lateral on the insulating half-joists, push which will have the effect of bringing them closer to the load-bearing component, by sliding them on the work surface, until '' to an energetic bringing into contact of all the parts, previously coated with glue. The pressure having obtained the assembly of the components will be maintained by an appropriate clamping device during the time necessary for the setting of the adhesive used.

La figure I représente en coupe le composant porteur (I),plaçé sur ses appuis d'extrèmités (non représentés par simplification), il est encadre par les deux demisolives isolantes (2) disposées en attente à sa droite et à sa gauche sur le plan de travail (7),lequel est un peu inférieur au niveau de la sous-façe du composant porteur (I) pour ménager un passage suffisant,au cours de 1' opération d'assemblage aux languettes d'isolation (4)situées à la base de chaque demi-solive isolante(2).Figure I shows in section the carrier component (I), placed on its end supports (not shown for simplification), it is framed by the two insulating demisolives (2) arranged waiting on its right and left on the work surface (7), which is slightly lower than the level of the under-face of the carrier component (I) to provide sufficient passage, during the assembly operation to the insulation tabs (4) located at the base of each insulating half-joist (2).

La figure 2 représente,toujours en coupe, le résultat obtenu par le proçédé de fabrication à caractère nouveau et selon l'invention Elle montre le composant porteur (I),solidaire des deux demi-solives isolantes (2) reconstituant ainsi,dans son prinçipe comme dans ses fonctions mécaniques et thermiques,la solive isolante autoporteuse selon le Brevet français 84I9570. Figure 2 shows, still in section, the result obtained by the manufacturing process of a new nature and according to the invention It shows the carrier component (I), integral with the two insulating half-joists (2) thus reconstituting, in its principle as in its mechanical and thermal functions, the self-supporting insulating joist according to French patent 84I9570.

Cette meme figure 2 montre également,matérialisée par des flèches,la direction des toussées ayant opéré l'assemblage et la solidarisation par collage des composants; elle montre enfin comment les languettes d'isolation (4) peuvent comporter un dispositif de liaison (5) qui renforçe la cohésion de ces éléments.This same FIG. 2 also shows, materialized by arrows, the direction of the coughs having operated the assembly and the joining by gluing of the components; it finally shows how the insulation tabs (4) can include a connecting device (5) which strengthens the cohesion of these elements.

La présente invention offre en plus l'avantage d'une grande souplesse d'application.Elle permet en effet de décomposer l'élaboration des solives isolantes autoporteuses en trois phases opérationnelles distinctes,dont l'intérêt est qu'il est possible,sans inconvénients,de les effectuer en des lieux et à des moments diffa rents.La première phase est la production de tous les éléments du plancher que décrit le Brevet français 84I9570,à savoir la solive isolante trapèzoidale et l'entrevous également isolant et trapèzoidal qui lui est complémentaire,çité içi pour mémoire car il n'est aucunement conçerné par le nouveau proçédé de fabrication, qui ne vise que les solives isolantes autoporteuses du plancher. The present invention also offers the advantage of great application flexibility, which makes it possible to break down the production of self-supporting insulating joists into three distinct operational phases, the advantage of which is that it is possible without disadvantages , to carry them out in different places and at different times. The first phase is the production of all the floor elements described in French Patent 84I9570, namely the trapezoidal insulating joist and the equally insulating and trapezoidal interjoist complementary, here mentioned for the record because it is in no way understood by the new manufacturing process, which only targets the self-supporting insulating joists of the floor.

La seconde phase est la fabrication des composants porteurs des solives,tels que définis par le présent texte,et dont la fonction est de rendre ces solives isolantes également autoporteuses;ces composants porteurs ont un encombrement latéral réduit et une masse métrique modérée,caractéristiques autorisant leur transport sur d'assez grandes distances sans trop alourdir leur coût final. Ceçi va permet firme à une seule unité de production d'alimenter plusieurs sites d'assemblage,m & me situés dans des régions économiques différentes.The second phase is the manufacture of the load-bearing components of the joists, as defined by the present text, and whose function is to make these insulating joists also self-supporting; these load-bearing components have a reduced lateral size and a moderate metric mass, characteristics allowing their transport over fairly large distances without increasing the final cost too much. This will allow a single production unit to supply several assembly sites, even located in different economic regions.

La troisième phase opérationnelle est l'assemblage solidarisant par collage les composants constituant la solive isolante autoporteuse;par cette dernière opération on obtient de façon nouvelle un élément de construction immédiatement utilisable,en assoçiation avec les entrevous isolants du système de plancher.The third operational phase is the assembly joining by gluing the components constituting the self-supporting insulating joist; by this last operation we obtain in a new way an immediately usable construction element, in association with the insulating interjoists of the floor system.

L'efficaçité de cet assemblage collé est au moins égale à celle obtenue,selon le proçédé actuellement utilisé,par la simple adhérence d'un béton très plastique coulé sur l'isolant.The efficiency of this bonded assembly is at least equal to that obtained, according to the method currently used, by the simple adhesion of a very plastic concrete poured onto the insulation.

Le site,ou atelier d'assemblage sera avantageusement installé à proximité de l'usine productrice des composants isolants du système,pour réduire le plus possible le coût de transport de ceux-çi,très légers mais aussi très volumineux.The site, or assembly workshop, will advantageously be installed near the factory producing the insulating components of the system, to reduce as much as possible the cost of transporting these, very light but also very bulky.

Le proçédé de fabrication selon la présente invention offre les avantages économi- quels énumérés çi-après premièrement,la simplification des taches,ramenées à assembler par collage deux composants industriels finis. Deuxièmement,la réduction de l'inçidence main-d'oeu vue, le travail à l'atelier d'assemblage se bornant à des manutentions,et à la conduite d'un matériel mécanique simple et aisément automatisable Troisièmement,le proçédé selon l'invention permet de satisfaire les demandes dans un délai de quelques heures,alors qu'actuellement,sans traitement thermique du béton et sans stock constitué à l'avance,ce délai est de huit à dix jours. Quatrièmement on allège les frais de contrôle qualitatif,déja effectué en amont,sur tous les composants de la solive isolante autoporteuse,qui sont des produits industriels finis,et entièrement définis dans leurs dimensions et leurs performances. Enfin et cinquièmement, le site d'assemblage,exploitant du plancher isolant,peut élargir notablement son aire de diffusion commerçiale,car la modification du proçédé de fabrication selon 1' invention aura généré une réduction de ses coûts de revient autorisant, sans alourdir son prix de vente aux entreprises,à livrer tous les éléments du plancher isolant à une plus grande distance du site d'assemblage. The manufacturing process according to the present invention offers the economic advantages listed below, firstly, the simplification of the tasks, reduced to joining by gluing two finished industrial components. Secondly, the reduction in the incidence of labor seen, work in the assembly workshop being limited to handling, and to the operation of simple mechanical equipment which is easily automated Thirdly, the process according to invention allows requests to be satisfied within a few hours, while currently, without heat treatment of the concrete and without stock built up in advance, this period is eight to ten days. Fourthly, the costs of quality control, already carried out upstream, are reduced on all the components of the self-supporting insulating joist, which are finished industrial products, and fully defined in their dimensions and performance. Finally and fifthly, the assembly site, exploiting insulating floors, can significantly expand its commercial distribution area, because the modification of the manufacturing process according to the invention will have generated a reduction in its authorizing costs, without increasing its price sale to companies, to deliver all the elements of the insulating floor at a greater distance from the assembly site.
