Abstract

The subject of the present invention is permanent formwork for building load-bearing partitions and walls which has the distinctive feature of comprising : a panel 1 made of expanded plastic having parallel foldings, as well as two wire nettings 4, 5 associated with the opposite sides of the panel 1 and connected together by transverse bracing elements 6 which pass through the said panel 1.

Description

La présente invention a pour objet un coffrage perdu pour la réalisation de cloisons et de murs portants ayant des caractéristiques d'isolation thermique et acoustique. The present invention relates to a lost formwork for the production of partitions and load-bearing walls having thermal and acoustic insulation characteristics.

Le but technique de la présente invention est de réaliser un coffrage du type susmentionné ayant un prix de revient économique et un poids réduit pour pouvoir être mis en oeuvre avec facilité tout en garantissant un degré élevé d'isolation thermique et acoustique. The technical aim of the present invention is to produce a formwork of the aforementioned type having an economic cost price and a reduced weight so that it can be implemented with ease while guaranteeing a high degree of thermal and acoustic insulation.

Ce but est atteint par le coffrage selon la présente invention, caractérisé par le fait qu'il comprend un panneau, de préférence en matière plastique expansée, présentant des plissements parallèles et doté de deux treillages métalliques associés aux faces opposées du panneau et reliés entre eux par des éléments transversaux qui traversent ce même panneau. This object is achieved by the formwork according to the present invention, characterized in that it comprises a panel, preferably of expanded plastic material, having parallel folds and provided with two metal trellises associated with the opposite faces of the panel and interconnected by transverse elements which cross this same panel.

D'autres caractéristiques de la présente invention ressortiront plus clairement de la description qui va suivre, donnée ici en regard des dessins annexés sur lesquels
- La figure 1 est une vue en perspective d'une partie d'un coffrage pour la réalisation d'une cloison,
- La figure 2 est une vue en perspective d'une partie d'un double coffrage pour la réalisation d'un mur portant,
- La figure 3 montre un mode d'emploi pratique du coffrage de la figure 2.
Other characteristics of the present invention will emerge more clearly from the description which follows, given here with reference to the appended drawings in which
FIG. 1 is a perspective view of part of a formwork for producing a partition,
FIG. 2 is a perspective view of part of a double formwork for producing a bearing wall,
- Figure 3 shows a practical manual of the formwork of Figure 2.

Conformément à la figure 1, le coffrage comprend un panneau 1 en matière plastique expansé, ayant des propriétés d'isolation thermique et acoustique. In accordance with FIG. 1, the formwork comprises a panel 1 made of expanded plastic, having thermal and acoustic insulation properties.

Le panneau 1 présente des plissements sous forme d'ondulations dont les creux sont désignés avec la référence 2 et les sommets avec la référence 3. La mise en oeuvre du panneau 1 s'effectue de manière à ce que les plissements soient verticaux. The panel 1 has folds in the form of undulations, the hollows of which are designated with the reference 2 and the vertices with the reference 3. The implementation of the panel 1 takes place so that the folds are vertical.

En contact tangentiel avec les sommets 3 des ondulations des deux côtés opposés du panneau 1 sont disposés deux treillages métalliques 4, 5 reliés entre eux par des éléments transversaux 6 qui traversent le panneau 1.  In tangential contact with the vertices 3 of the undulations on the two opposite sides of the panel 1 are arranged two metal trellises 4, 5 connected together by transverse elements 6 which pass through the panel 1.

Les treillages 4, 5 sont, par exemple, du type électro-soudé et ils sont constitués par des fers 7 et 8 soudés orthogonalement entre eux de manière à donner lieu à des mailles carrées. The trellises 4, 5 are, for example, of the electro-welded type and they consist of irons 7 and 8 welded orthogonally to each other so as to give rise to square meshes.

La distance entre les fers 7 qui s'étendent parallèlement aux ondulations du panneau est égale à la distance entre les sommets 3 de ces mêmes ondulations. Les treillages sont appliqués sur le panneau de manière à ce que les fers 7 soient positionnés en face des creux 2 et de préférence sur le plan médian de ces mêmes creux.  The distance between the irons 7 which extend parallel to the undulations of the panel is equal to the distance between the vertices 3 of these same undulations. The trellises are applied to the panel so that the bars 7 are positioned opposite the recesses 2 and preferably on the median plane of these same recesses.

La surface ondulée du panneau 1 permet un ancrage stable de l'enduit ou crépi 9 qui peut envelopper complètement les fers verticaux 7. The corrugated surface of the panel 1 allows a stable anchoring of the plaster or plaster 9 which can completely envelop the vertical bars 7.

Grâce à cette solution, on obtient un mur dont le panneau intermédiaire constitue une efficace barrière thermique et acoustique. Thanks to this solution, a wall is obtained, the intermediate panel of which constitutes an effective thermal and acoustic barrier.

Outre que pour la réalisation de cloisons, le coffrage selon l'invention peut être également utilisé comme double coffrage pour la réalisation de murs portants. Besides that for the production of partitions, the formwork according to the invention can also be used as double formwork for the production of load-bearing walls.

Dans ce cas (voir figure 2), on prévoit deux coffrages analogues à ceux qui sont décrits à la figure 1, maintenus à une distance réciproque définie par des éléments d'entretoisement 10 de manière à former un espace intermédiaire 11 apte à accueillir une coulée de béton sans avoir recours à des planches ou autre genre d'armatures. In this case (see FIG. 2), two formworks similar to those described in FIG. 1 are provided, maintained at a reciprocal distance defined by bracing elements 10 so as to form an intermediate space 11 capable of accommodating a casting. of concrete without using planks or any other kind of reinforcement.

Les treillages intérieurs collaborent avec le béton, dans lequel ils restent complètement noyés en donnant lieu à une coulée de béton armé d'une grande portance et résistance aux poussées horizontale et aux éventuelles actions sismiques. The internal trellises work with the concrete, in which they remain completely submerged, giving rise to a pouring of reinforced concrete with great lift and resistance to horizontal thrusts and possible seismic actions.

En même temps, ce double coffrage constitue un double écran thermique et acoustique pour toute la construction, ce qui s avère particulièrement avantageux car les murs portants sont normalement périmétraux. At the same time, this double formwork constitutes a double thermal and acoustic screen for the entire construction, which is particularly advantageous since the load-bearing walls are normally perimeter.

Le grand pouvoir isolant du coffrage se manifeste également en phase d'exécution de la coulée, car le béton se trouve protégé contre tout réchauffement excessif dû au rayonnement du soleil, ou contre le gel lorsque la température descend en-dessous de zéro. The great insulating power of the formwork also manifests itself during the casting phase, because the concrete is protected against excessive heating due to the sun's rays, or against freezing when the temperature drops below zero.

En chantier, l'espace intermédiaire 11 pourra varier selon les désirs en fonction de l'épaisseur des coulées. De même, la section des fers qui constituent l'armature de la coulée, c'est-à-dire les treillages intérieurs, pourra être augmentée par rapport à celle des treillages extérieurs en fonction des charges. On site, the intermediate space 11 may vary as desired depending on the thickness of the flows. Likewise, the section of irons which constitute the reinforcement of the casting, that is to say the internal trellises, may be increased compared to that of the external trellises as a function of the loads.

Par ailleurs, dans l'espace intermédiaire 11 on pourra loger les installations électriques, thermiques et hydrauliques qui pourront trouver place dans des goulottes facilement réalisables sur le panneau isolant. Furthermore, in the intermediate space 11 it will be possible to house the electrical, thermal and hydraulic installations which may find a place in troughs which can easily be produced on the insulating panel.

La continuité de la coulée de béton entre un coffrage et 11 autre est assurée par des ronds 12 horizontaux associés aux éléments d'entretoisement 10. The continuity of the concrete pouring between a formwork and 11 other is ensured by horizontal rounds 12 associated with the bracing elements 10.

Le coffrage qui vient d'être décrit peut être adapté avec une extrême facilité aux différentes exigences constructives. La figure 3 montre quelques unes de ces possibilités pour la réalisation de parapets 13 et de linteaux 14 pour fenêtres.  The formwork which has just been described can be adapted with extreme ease to the various constructive requirements. Figure 3 shows some of these possibilities for making parapets 13 and lintels 14 for windows.

Les angles pourront être obtenus en raccourcissant le coffrage intérieur d'une valeur égale à l'épaisseur du mur. The angles can be obtained by shortening the interior formwork by a value equal to the thickness of the wall.

Les planchers s'appuient sur les coffrages et ils sont soutenus pendant l'exécution de la coulée.  The floors rest on the formwork and are supported during the execution of the casting.
