Description

L'invention concerne les prédalles en béton qui sont préfabriquées sur un site de production pour être transportées sur un chantier de construction d'un bâtiment avant d'y être installées. De telles prédalles sont destinées à recevoir sur leurs faces supérieures du béton formant une dalle de compression de façon à constituer, conjointement avec cette dalle de compression un plancher. ARRIERE PLAN DE L'INVENTION De telles prédalles sont avantageusement fabri- quées en béton précontraint de manière à être suffisamment légères pour être transportables, et suffisamment résistantes pour supporter le poids de la dalle de compression coulée sur chantier.The invention relates to concrete slabs which are prefabricated on a production site to be transported to a construction site of a building before being installed there. Such slabs are intended to receive on their upper faces concrete forming a compression slab so as to constitute, together with the slab compression a floor. BACKGROUND OF THE INVENTION Such pre-slabs are advantageously made of prestressed concrete so as to be light enough to be transportable, and sufficiently strong to support the weight of the cast-on-site compression slab.

Sur un chantier de construction d'un bâtiment, la réalisation d'un plancher en utilisant de telles prédalles consiste dans un premier temps à installer un ensemble de prédalles en appui sur des murs de refend ou des poutres du bâtiment, de manière à couvrir toute la sur- face du plancher à réaliser. Une fois que ces prédalles sont installées, des opérateurs placent sur la face supérieure qu'elles délimitent, un ensemble de ferraillages pour former les armatures de la dalle de compression à couler.On a construction site of a building, the realization of a floor using such pre-slabs consists first of all in installing a set of slabs resting on the walls of slits or beams of the building, so as to cover any the surface of the floor to be made. Once these slabs are installed, operators place on the upper face they delimit, a set of reinforcement to form the reinforcements of the compression slab to flow.

Le coffrage de la dalle de compression à couler a ainsi un fond constitué par la face supérieure des pré-dalles, et un rebord périphérique qui est formé en partie par les murs entourant le plancher à construire, et en partie par des éléments additionnels en bois ou autre que les opérateurs ajoutent le long des bords libres corres- pondant par exemple à des balcons du bâtiment. Le coulage du béton de la dalle de compression est ainsi réalisé directement sur les prédalles. En pratique, la mise en oeuvre de prédalles pour bâtir les plan- chers d'un bâtiment permet de gagner un temps considéra- ble sur la construction de ce bâtiment. OBJET DE L'INVENTION Le but de l'invention est de proposer une structure de prédalle permettant de réduire encore le temps de construction d'un bâtiment. RESUME DE L'INVENTION A cet effet, l'invention a pour objet une prédalle destinée à supporter le béton d'une dalle de compression pour constituer conjointement avec cette dalle de compression le plancher d'un bâtiment, cette prédalle comportant un corps en béton et au moins une embase de fixation ancrée dans un bord du corps en béton, cette embase de fixation étant destinée à recevoir un élément de retenue se solidarisant rigidement à cette em- base par emboîtement afin de dépasser de la face supé- rieure du corps de prédalle pour constituer une portion de coffrage perdu du béton de la dalle de compression. Avec cette solution, le rebord périphérique du coffrage de la dalle de compression peut être très rapi- dement mis en oeuvre dans les régions correspondant à un bord libre du plancher à fabriquer : il n'est plus nécessaire aux opérateurs de confectionner un rebord de coffrage avec des éléments en bois ou autre, il leur suffit d'emboîter dans les embases de fixation des éléments de retenue de type becquets ou analogues prévus à cet effet. L'invention concerne également un système compre- nant une prédalle telle que définie ci-dessus, et au moins un élément de retenue ayant une forme de becquet. L'invention concerne également un système compre- nant une prédalle telle que définie ci-dessus, et au moins un élément de retenue formant becquet ainsi que isolant thermique. BREVE DESCRIPTION DES FIGURES La figure 1 montre une portion de prédalle pour- vue conformément à l'invention d'une embase de fixation et d'un élément venant se fixer à cette embase ; La figure 2 montre schématiquement en coupe transversale une structure de bâtiment construit avec la prédalle selon l'invention ; La figure 3 montre en perspective un élément de retenue sous forme de becquet destiné à être solidarisé à une embase de fixation d'une prédalle selon l'invention ; La figure 4 montre en perspective un élément de retenue formant à la fois becquet et isolant et qui est destiné à être solidarisé à une embase de fixation d'une prédalle selon l'invention ; La figure 5 est une vue en perspective d'un élé- ment de retenue formant à la fois becquet isolant et organe structurel qui est destiné à être solidarisé à une embase de fixation d'une prédalle selon l'invention. DESCRIPTION DETAILLEE DE L'INVENTION L'idée à la base de l'invention est de simplifier la mise en oeuvre du coffrage de la dalle de compression. Ceci est obtenu en prévoyant des embases de fixation au niveau du bord périphérique délimité par l'ensemble des prédalles sur lesquelles doit être coulée la dalle de compression. Des becquets dépassant vers le haut peuvent ainsi être solidarisés à ces embases de fixation pour constituer tout ou partie du rebord périphérique du cof- frage de la dalle de compression. La prédalle selon l'invention qui est repérée par 1 dans la figure 1 comporte un corps en béton précontraint 2 comprenant des câbles de précontrainte 3 orientés longitudinalement et parallèlement les uns aux autres. Dans l'exemple de la figure 1, l'un des bords longitudinaux de cette prédalle est équipé d'une embase de fixation 4 qui est rigidement solidarisée au corps en béton 2 en étant ancrée dans celui-ci. Cette embase comporte une portion inférieure d'ancrage, repérée par 6, qui est enrobée dans le béton du corps de prédalle 2, et elle comporte une portion supérieure de fixation 7 qui dépasse de la face supérieure 8 du corps de prédalle 2 et qui est destinée à recevoir un élément complémentaire qui est ici un élément de rete- nue en forme de becquet repéré par 9 dans l'exemple de la figure 1. L'embase est constituée par exemple par une pièce en matière plastique, en tôle ou encore en béton, et elle peut être solidarisée au corps de prédalle par des élé- ments de fixation de type vis ou autre, ou bien par sur- moulage durant la fabrication de ce corps de prédalle. Dans ce cas, l'embase est installée dans le moule de fabrication du corps de prédalle en étant positionnée le long des rives de ce moule, et elle est le cas échéant maintenue en position par des organes de maintien exter- nes. Une fois que le béton a été coulé et a terminé de prendre, l'embase qui comporte avantageusement des reliefs à sa face en contact avec le béton du corps de pré- dalle, est alors rigidement solidarisée au corps de pré- dalle pour former avec celui-ci un tout rigide. L'invention permet ainsi de couler une dalle de compression sur un ensemble de prédalles qui n'est pas bordé de murs ou cloisons sur tout son pourtour au moment du coulage, comme par exemple dans l'architecture de construction de la figure 2. Cette construction correspond à celle d'un bâti- ment à plusieurs étages dont les différents planchers sont portés par les deux murs de pignon et par différents murs de refend intérieurs du bâtiment, mais dans lequel les murs longitudinaux externes sont des murs rideaux, montés après le coulage des planchers. Pour construire ce bâtiment, on a installé un en- semble de prédalles précontraintes 11-15 contiguës et jointives qui sont portées par différents murs de refend intérieurs tels que le mur 17, et par les murs de pignon qui ne sont pas représentés. Chaque prédalle possédant un bord longitudinal longeant le mur rideau à installer en dernier lieu, comme la prédalle 11, est une prédalle selon l'invention c'est- à-dire pourvue le long de son bord longitudinal externe d'une série d'embases de fixation non visibles dans la figure 2. Conformément à l'invention, des éléments de rete- nue sous forme de becquets 18 sont fixés au bord longitu- dinal externe de la prédalle 11 pour constituer une portion du rebord périphérique du coffrage de la dalle de compression 19 à couler. Ainsi, comme visible dans la figure 2, le coffrage de la dalle de compression 19 a un fond qui correspond à la face supérieure des prédalles, et un rebord périphérique qui est délimité par les murs de pignon non visibles, par le mur 17', et par différents éléments de retenue 18 rapportés sur les embases de fixation.The formwork of the compression slab to be cast thus has a bottom formed by the upper face of the pre-slabs, and a peripheral rim which is formed in part by the walls surrounding the floor to be built, and partly by additional wooden elements. or other than the operators add along the free edges corre- sponding for example to the balconies of the building. The concrete pouring of the compression slab is thus carried out directly on the slabs. In practice, the use of slabs to build the floors of a building saves considerable time on the construction of this building. OBJECT OF THE INVENTION The object of the invention is to provide a predalle structure to further reduce the construction time of a building. SUMMARY OF THE INVENTION To this end, the subject of the invention is a slab intended to support the concrete of a compression slab to constitute together with this slab of compression the floor of a building, this slab comprising a concrete body. and at least one anchoring base anchored in an edge of the concrete body, this fastening base being intended to receive a retaining element rigidly fastened to this base by interlocking in order to protrude from the upper face of the body of the body. prefabricated to constitute a portion of lost formwork of the concrete of the compression slab. With this solution, the peripheral edge of the formwork of the compression slab can be used very quickly in the regions corresponding to a free edge of the floor to be manufactured: it is no longer necessary for operators to make a formwork rim. with elements of wood or other, they simply need to fit into the mounting bases of the spoil-type retaining elements or the like provided for this purpose. The invention also relates to a system comprising a predalle as defined above, and at least one retaining element having a spoiler shape. The invention also relates to a system comprising a predalle as defined above, and at least one spoiler retaining element as well as thermal insulation. BRIEF DESCRIPTION OF THE FIGURES FIG. 1 shows a portion of a predalle designed according to the invention for a fixing base and an element that is fixed to this base; Figure 2 shows schematically in cross section a building structure constructed with the predalle according to the invention; Figure 3 shows in perspective a retaining element in the form of spoiler intended to be secured to a mounting base of a predalle according to the invention; Figure 4 shows in perspective a retaining member forming both spoiler and insulator and which is intended to be secured to a mounting base of a predalle according to the invention; Figure 5 is a perspective view of a retaining element forming both an insulating spoiler and structural member which is intended to be secured to a mounting base of a predalle according to the invention. DETAILED DESCRIPTION OF THE INVENTION The idea underlying the invention is to simplify the implementation of the formwork of the compression slab. This is achieved by providing mounting bases at the peripheral edge defined by all the predalles on which the compression slab is to be cast. Upwardly protruding spoilers can thus be secured to these mounting bases to form all or part of the peripheral rim of the coffering of the compression slab. The predalle according to the invention, which is indicated by 1 in FIG. 1, comprises a prestressed concrete body 2 comprising prestressing cables 3 oriented longitudinally and parallel to one another. In the example of Figure 1, one of the longitudinal edges of this predalle is equipped with a mounting base 4 which is rigidly secured to the concrete body 2 being anchored therein. This base comprises a lower anchoring portion, marked by 6, which is embedded in the concrete of the pre-slab body 2, and it comprises an upper fixing portion 7 which protrudes from the upper face 8 of the pre-slab body 2 and which is intended to receive a complementary element which is here a spoiler-shaped retaining element marked by 9 in the example of FIG. 1. The base is constituted for example by a piece of plastic material, sheet metal or even concrete, and it can be secured to the pre-slab body by fastening elements of the screw or other type, or by over-molding during the manufacture of this pre-slab body. In this case, the base is installed in the mold of the pre-slab body being positioned along the edges of this mold, and it is optionally held in position by external holding members. Once the concrete has been poured and finished, the base which advantageously has reliefs on its face in contact with the concrete of the pre-slab body, is then rigidly secured to the pre-slab body to form with this one a rigid whole. The invention thus makes it possible to cast a compression slab on a set of slabs which is not bordered by walls or partitions all around its periphery at the time of pouring, as for example in the construction architecture of FIG. The construction corresponds to that of a multi-storey building, the floors of which are supported by the two gable walls and by various interior walls of the building, but in which the external longitudinal walls are curtain walls, mounted after the pouring floors. To construct this building, a set of contiguous and contiguous prestressed slabs 11-15 have been installed which are carried by different interior slit walls such as the wall 17, and by the gable walls which are not shown. Each predalle having a longitudinal edge along the curtain wall to be installed last, as the predalle 11, is a predalle according to the invention that is to say provided along its outer longitudinal edge of a series of bases 2. In accordance with the invention, retaining elements in the form of spoilers 18 are attached to the outer longitudinal edge of the pre-slab 11 to form a portion of the peripheral rim of the formwork of the slab. of compression 19 to flow. Thus, as can be seen in FIG. 2, the formwork of the compression slab 19 has a bottom that corresponds to the upper face of the slabs, and a peripheral rim which is delimited by the non-visible sprocket walls, by the wall 17 ', and by different retaining elements 18 reported on the mounting bases.

Le montage du plancher du second étage est réali- sé de la même manière, en installant l'ensemble des pré-dalles 11,-15' et en fixant les becquets 18' au bord longitudinal externe de la prédalle 11', de manière à procéder au coulage de la dalle de compression 19' du deuxième étage. Le mur rideau qui est installé après fabrication des différents planchers, comporte plusieurs tronçons 2121'' qui sont raccordés les uns aux autres par l'intermédiaire d'un becquet 18, 18'.The mounting of the floor of the second floor is carried out in the same way, by installing all the pre-slabs 11, -15 'and fixing the spoilers 18' to the outer longitudinal edge of the slab 11 ', so as to proceed to pour the compression slab 19 'of the second stage. The curtain wall which is installed after manufacture of the different floors, comprises several sections 2121 '' which are connected to each other via a spoiler 18, 18 '.

A cet effet, dans l'exemple de construction de la figure 2, les éléments de retenue 18 et 18' constituent, outre des becquets de coffrage des dalles de compression 19 et 19', des éléments thermiquement isolants. Leur pouvoir d'isolation thermique permet de casser le pont ther- mique formé par l'interface du plancher avec le mur exté- rieur en rideau, de manière à réduire les déperditions thermiques du bâtiment. Comme illustré aux figures 3 à 5, différents élé- ments de retenue peuvent être fixés à l'embase 4. Dans l'exemple de la figure 3, l'élément de retenue est un simple becquet 9, constituant une paroi verticale constituant un rebord de hauteur relativement importante s'élevant au dessus de la face supérieure de la prédalle lorsqu'il est en place.For this purpose, in the embodiment of Figure 2, the retaining elements 18 and 18 'constitute, in addition to formwork spoil compression slabs 19 and 19', thermally insulating elements. Their thermal insulating power makes it possible to break the thermal bridge formed by the interface of the floor with the external curtain wall, so as to reduce the thermal losses of the building. As illustrated in FIGS. 3 to 5, various retaining elements can be fixed to the base 4. In the example of FIG. 3, the retaining element is a simple spoiler 9 constituting a vertical wall constituting a rim. relatively high height rising above the upper face of the predalle when in place.

Ce béquet 9 a une forme générale de plaque dont la portion inférieure est pourvue d'une fente, repérée par 22, s'étendant longitudinalement et débouchant vers le bas du becquet, et grâce à laquelle ce becquet vient s'emboîter sur la portion supérieure 7 de l'embase de fixation 4 pour se fixer rigidement à celle-ci par emboî- tement et/ou encliquetage. L'élément de retenue 23 de la figure 4 constitue quant à lui à la fois un becquet et un isolant thermique. Il comporte une structure de base 24 identique au becquet 9, et par laquelle il se fixe en s'emboîtant à l'embase 4, mais en outre un matériau isolant 26 est rapporté sur la face externe de la structure de base 24 de manière à lui conférer les fonctionnalités supplémentaires d'isolant thermique.This spoiler 9 has a general shape of plate whose lower portion is provided with a slot, marked by 22, extending longitudinally and opening towards the bottom of the spoiler, and thanks to which this spoiler comes to fit on the upper portion 7 of the mounting base 4 to rigidly attach to it by interlocking and / or snap-fastening. The retaining element 23 of Figure 4 is both a spoiler and a thermal insulator. It comprises a basic structure 24 identical to the spoiler 9, and by which it is fixed by fitting to the base 4, but in addition an insulating material 26 is attached to the outer face of the base structure 24 so as to give it the extra features of thermal insulation.

L'élément 27 qui est représenté à la figure 5 constitue également un élément isolant comme l'élément 23 de la figure 4, mais il constitue en outre un organe structurel par lequel la chape de compression peut être solidarisée rigidement à un élément de mur externe struc- turel. Comme visible dans cette figure 5, cet élément 27 comporte une structure 28 de même section que le becquet 9 et par lequel il se fixe à l'embase de fixation selon l'invention, ainsi qu'un matériau isolant 29 rapporté à la face externe de sa structure 28. Mais cet élément 27 comporte en outre différents éléments de ferraillage 31 qui traversent sa structure 28 ainsi que le matériau isolant 29, de sorte qu'ils constituent des fers dépassant des deux côtés du corps de cet élément 27.The element 27 which is represented in FIG. 5 also constitutes an insulating element like the element 23 of FIG. 4, but it also constitutes a structural member by means of which the compression cap may be rigidly attached to an external wall element. structural. As can be seen in this FIG. 5, this element 27 comprises a structure 28 of the same section as the spoiler 9 and by which it attaches to the attachment base according to the invention, as well as an insulating material 29 attached to the external face its structure 28. But this element 27 further comprises different elements of reinforcement 31 which pass through its structure 28 as well as the insulating material 29, so that they constitute irons protruding from both sides of the body of this element 27.

En pratique après coulage du béton de la dalle de compression, les fers dépassant vers l'intérieur sont enrobés, de sorte qu'ils sont rigidement solidarisés à cette dalle de béton. La portion de ces fers qui dépasse de l'autre côté de l'élément 27 peut alors à son tour être noyée dans un élément de béton externe tel qu'un mur externe, ce qui permet de lier rigidement la dalle de compression du plancher à un élément de béton externe.In practice after pouring the concrete of the compression slab, the irons protruding inwards are coated, so that they are rigidly secured to the concrete slab. The portion of these irons that protrude from the other side of the element 27 can then in turn be embedded in an external concrete element such as an external wall, which makes it possible to rigidly bind the compression slab of the floor to an external concrete element.
