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.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.

ARRIERE PLAN DE L'INVENTIONBACKGROUND OF THE INVENTION

De telles prédalles sont avantageusement fabriquées 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.Such 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 compression slab cast on site.

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 surface du plancher à réaliser.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.

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.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 prédalles, 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 correspondant par exemple à des balcons du bâtiment.The formwork of the compression slab to be poured thus has a bottom formed by the upper face of the slabs, and a peripheral rim which is formed in part by the walls surrounding the floor to be built, and partly by additional elements of wood or other that the operators add along the free edges corresponding for example to balconies of the building.

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 planchers d'un bâtiment permet de gagner un temps considé-rable sur la construction de ce bâtiment.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 a considerable amount of time on the construction of this building.

L'art antérieur est notamment illustré par le document DE 20 2004 001685 U1 .The prior art is particularly illustrated by the document DE 20 2004 001685 U1 .

Le document FR 2 910 033 décrit une prédalle selon le préambule de la revendication 1.The document FR 2 910 033 describes a predalle according to the preamble of claim 1.

OBJET DE L'INVENTIONOBJECT OF THE INVENTION

Le but de l'invention est de proposer une structure de prédalle permettant de réduire encore le temps de construction d'un bâtiment.The object of the invention is to provide a predalle structure to further reduce the construction time of a building.

RESUME DE L'INVENTIONSUMMARY OF THE INVENTION

A cet effet, l'invention a pour objet une prédalle selon la revendication 1.For this purpose, the subject of the invention is a slab according to claim 1.

Avec cette solution, le rebord périphérique du coffrage de la dalle de compression peut être très rapidement 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.With this solution, the peripheral edge of the formwork of the compression slab can be very quickly implemented 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 wooden or other, they just need to fit into the mounting bases of the spoil-type retention elements or the like provided for this purpose.

DESCRIPTION DETAILLEE DE L'INVENTIONDETAILED DESCRIPTION OF THE 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 coffrage de la dalle de compression.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 formwork of the compression slab.

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.The predalle according to the invention which is marked by 1 in the figure 1 comprises a prestressed concrete body 2 comprising prestressing cables 3 oriented longitudinally and parallel to each other. In the example of the 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.

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 retenue en forme de becquet repéré par 9 dans l'exemple de la figure 1.This base comprises a lower anchoring portion, marked by 6, which is embedded in the concrete 2, and it has 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 the figure 1 .

L'embase est constituée par une pièce en matière plastique, en tôle ou encore en béton, et elle peut être solidarisée au corps de prédalle par des éléments de fixation de type vis ou autre, ou bien par surmoulage 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 externes.The base consists of a piece of plastic material, sheet metal or concrete, and it can be secured to the pre-slab body by fastening elements of the screw type or otherwise, or by overmoulding during the manufacture of this body of floor plate. 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.

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 prédalle, est alors rigidement solidarisée au corps de prédalle pour former avec celui-ci un tout rigide.Once the concrete has been poured and finished taking, 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 it a all rigid.

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.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 the slab. figure 2 .

Cette construction correspond à celle d'un bâtiment 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.This construction corresponds to that of a multi-storey building, the floors of which are supported by the two gable walls and by different interior walls of the building, but in which the external longitudinal walls are curtain walls, mounted after casting. floors.

Pour construire ce bâtiment, on a installé un ensemble 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.To build this building, a set of adjoining contiguous and contiguous prestressed slabs 1115 are installed, which are supported by different slitting walls. interiors such as the wall 17, and by the gable walls that are not shown.

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.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 fasteners not visible in the figure 2 .

Conformément à l'invention, des éléments de retenue sous forme de becquets 18 sont fixés au bord longitudinal 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.According to 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 flange of the formwork of the compression slab 19 to be cast. So, as visible in the figure 2 , the formwork of the compression slab 19 has a bottom which corresponds to the upper face of the slabs, and a peripheral rim which is delimited by the not visible sprocket walls, by the wall 17 ', and by various retaining elements 18 on the mounting bases.

Le montage du plancher du second étage est réalisé de la même manière, en installant l'ensemble des prédalles 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.The mounting of the floor of the second floor is carried out in the same manner, by installing all the slabs 11'-15 'and fixing the spoilers 18' to the outer longitudinal edge of the slab 11 ', so as to proceed with the casting of the compression slab 19 'of the second stage.

Le mur rideau qui est installé après fabrication des différents planchers, comporte plusieurs tronçons 21-21" qui sont raccordés les uns aux autres par l'intermédiaire d'un becquet 18, 18'.The curtain wall which is installed after manufacture of the different floors, comprises several sections 21-21 "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 thermique formé par l'interface du plancher avec le mur extérieur en rideau, de manière à réduire les déperditions thermiques du bâtiment.For this purpose, in the construction example of the figure 2 , the retaining elements 18 and 18 'constitute, in addition to formwork spoilers of the compression slabs 19 and 19', thermally insulating elements. Their thermal insulation capacity makes it possible to break the thermal bridge formed by the interface of the floor with the external wall in curtain, so as to reduce thermal losses of the building.

Comme illustré aux figures 3 à 5, différents éléments 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.As illustrated in Figures 3 to 5 different holding elements may be attached to the base 4. In the example of the figure 3 , the retaining element is a simple spoiler 9 constituting a vertical wall constituting a relatively high rim of 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 emboîtement et/ou encliquetage.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.

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.The retainer 23 of the figure 4 for its part 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 structurel.Element 27 which is represented at figure 5 also constitutes an insulating element as element 23 of the figure 4 , but it also constitutes a structural member by which the compression cap can be rigidly secured to a structural external wall element.

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.As visible in this figure 5 this element 27 has a structure 28 of the same section as the spoiler 9 and by which it is fixed to the base of attachment according to the invention, and an insulating material 29 attached to the outer face of its structure 28. But this element 27 further comprises various 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.
