Abstract

The shutter has a mould base (1) formed by a plate having a top horizontal edge (4), a vertical plane top part (5) and a plane bottom part (6) inclined to the masonry (7) and extended by a return (8) lip in the same plane. Two identical lateral flanges or brackets (3) slide between an L-shaped top shutter box and the mould base. The brackets have an extension curved to form a notch (11) to hold and guide the mould base and a second extension curved to form a guide notch for the box.

Description

La présente invention concerne un coffrage pour la réalisation du côté intérieur des appuis de baie en béton. The present invention relates to a formwork for the production of the interior side of the concrete bay supports.

Le but de l'invention est de proposer un dispositif de coffrage facile à mettre en oeuvre et permettant de réaliser rapidement des appuis de baie conformes aux DTU 36.1 et à la norme NF B 23 305 et autorisant donc la pose de la menuiserie après l'exécution de l'appui de la fenêtre. The object of the invention is to propose a formwork device which is easy to implement and which makes it possible to quickly produce bay supports conforming to DTU 36.1 and to standard NF B 23 305 and therefore authorizing the installation of the joinery after the window sill execution.

A cet effet, l'invention a pour objet un coffrage pour côté intérieur d'appui de baie, caractérisé en ce qu'il est constitué d'un fond de moule formé d'une plaque comportant un rebord supérieur horizontal, une partie supérieure plane verticale et une partie inférieure plane inclinée vers la macçoonerie et prolongée par un retour situé dans le plan de ladite partie supérieure, d'un coffre regingot et de deux joues latérales identiques susceptibles de coulisser entre le fond du moule et le coffre regingot, le contour des joues correspondant sensiblement dans sa partie utile à la section de l'appui de baie dépassant la façade intérieure de la maçonnerie. To this end, the invention relates to a formwork for the inner side of the rack support, characterized in that it consists of a mold base formed by a plate having a horizontal upper rim, a flat upper part. vertical and a flat lower part inclined towards the masonry and extended by a return located in the plane of said upper part, of a gingham chest and of two identical side cheeks capable of sliding between the bottom of the mold and the gingham chest, the outline cheeks corresponding substantially in its useful part to the section of the bay support projecting beyond the interior facade of the masonry.

La mise en place d'un tel coffrage est très rapide puisqu'il suffit de positionner le fond de moule muni de ses joues et du coffre regingot au droit de la partie inférieure de l'ouverture pratiquée dans la maçonnerie en ménageant 3 cm supplémentaires de chaque côté pour faire les retours de regingot. The installation of such a formwork is very fast since it suffices to position the mold base provided with its cheeks and the gum box in line with the lower part of the opening made in the masonry, leaving an additional 3 cm of each side to make the gum returns.

Après serrage du coffrage contre la maçonnerie à l'aide par exemple de serre-joint prenant appui contre la partie supérieure verticale et le retour inférieur du fond de moule, on peut aussitôt couler le béton. La largeur du fond de moule et du coffre regingot correspond bien entendu aux dimensions normalisées des baies. After tightening the formwork against the masonry using for example a clamp pressing against the vertical upper part and the lower return of the mold base, the concrete can be poured immediately. The width of the bottom of the mold and the regingot trunk of course corresponds to the standardized dimensions of the bays.

D'autres caractéristiques et avantages ressortiront de la description qui va suivre d'un mode de réalisation du dispositif de l'invention, description donnée à titre d'exemple uniquement et en regard du dessin annexé sur lequel
- Fig. 1 représente une vue en élévation d'un coffrage
selon l'invention;
- Fig. 2 représente une vue en coupe suivant la ligne II-II
du coffrage de la Fig. 1
- Fig. 3 représente une vue de côté agrandie d'une joue du
coffrage, et
- Fig. 4 représente une section transversale du fond de
moule et du coffre regingot du dispositif de la Fig. 1.
Other characteristics and advantages will emerge from the description which follows of an embodiment of the device of the invention, description given by way of example only and with reference to the appended drawing in which
- Fig. 1 shows an elevation view of a formwork
according to the invention;
- Fig. 2 shows a sectional view along line II-II
of the formwork of FIG. 1
- Fig. 3 shows an enlarged side view of a cheek of the
formwork, and
- Fig. 4 shows a cross section of the bottom of
mold and trunk of the device of FIG. 1.

Le coffrage représenté (côté intérieur) sur la
Fig. 1 comprend un fond de moule 1, un coffre regingot 2 et deux joues latérales identiques 3.
The formwork shown (interior side) on the
Fig. 1 includes a mold base 1, a gingham trunk 2 and two identical side cheeks 3.

Le fond de moule 1 est formé par exemple d'une tble métallique pliée dont la longueur est sensiblement supérieure à la plus grande largeur de baie normalisée. The mold base 1 is formed, for example, of a folded metal plate whose length is substantially greater than the largest standardized bay width.

Ce fond de moule 1 dont la section transversale agrandie est représentée à la Fig. 4, comporte un rebord 4 horizontal tourné vers l'intérieur de la construction, une paroi supérieure plane verticale 5 et une paroi inférieure plane 6 inclinée vers la façade intérieure (symbolisée en 7 sur le dessin) et prolongée par un retour plan vertical 8 dans le plan de la partie 5. This mold base 1, the enlarged cross section of which is shown in FIG. 4, has a horizontal rim 4 facing towards the inside of the construction, a vertical flat upper wall 5 and a flat lower wall 6 inclined towards the internal facade (symbolized at 7 in the drawing) and extended by a vertical flat return 8 in the plan of part 5.

Le coffre regingot 2 a une section en L et est maintenu en place par les joues 3. Celles-ci ont une forme générale correspondant à la section (symbolisée en 9 sur la
Fig. 4) de l'appui de baie dépassant la façade intérieure 7 de la maçonnerie.
The regingot chest 2 has an L-shaped section and is held in place by the cheeks 3. These have a general shape corresponding to the section (symbolized at 9 on the
Fig. 4) the bay support projecting beyond the interior facade 7 of the masonry.

Afin de permettre le coulissement des joues 3 le long du fond de moule 1, les joues 3 comportent à leur partie supérieure un prolongement 10 recourbé vers le bas de manière à épouser le rebord 4, le prolongement 10 définissant une encoche 11 dans laquelle s'engage le rebord 4. In order to allow the cheeks 3 to slide along the bottom of the mold 1, the cheeks 3 have at their upper part an extension 10 bent downwards so as to match the rim 4, the extension 10 defining a notch 11 in which s engage edge 4.

De même, les joues 3 sont munies, côté maçonnerie, d'un prolongement 12 vers le haut définissant une encoche 13 dans laquelle s'engage partiellement l'aile horizontale du coffre regingot 2. Likewise, the cheeks 3 are provided, on the masonry side, with an upward extension 12 defining a notch 13 in which partially engages the horizontal wing of the thimble chest 2.

Les largeurs des encoches il et 13 sont sensiblement supérieures aux épaisseurs du rebord 4 et du coffre regingot 2 afin que les joues 3 puissent coulisser librement. The widths of the notches 11 and 13 are substantially greater than the thicknesses of the rim 4 and of the thimble trunk 2 so that the cheeks 3 can slide freely.

Les joues 3 sont par exemple réalisées en aluminium et ont une épaisseur de l'ordre de 15 mm. The cheeks 3 are for example made of aluminum and have a thickness of the order of 15 mm.

La mise en place d'un tel coffrage est tres rapide.  The installation of such formwork is very fast.

Les joues 3 qui coulissent librement le long du fond de moule 1 et du coffre regingot 2, sont positionnées facilement en regard des parois verticales et de l'ouverture de baie ménagée dans la maçonnerie en ménageant 3 cmf supplémentaires de chaque côté pour faire les retours de regingot. The cheeks 3 which slide freely along the bottom of the mold 1 and of the thimble chest 2, are easily positioned opposite the vertical walls and the opening of the opening in the masonry, leaving an additional 3 cmf on each side to return gum.

Il est à noter que le coffre regingot 2 peut être mis en place une fois les joues 3 positionnées.It should be noted that the trunk boot 2 can be put in place once the cheeks 3 positioned.

Les éléments du coffrage sont maintenus en place à l'aide de serre-joint symbolisés en 14 sur la Fig. 2 et prenant appui sur des cales 15 appliquées contre la face verticale 5 et le rebord 8 du fond de moule. The elements of the formwork are held in place using clamps symbolized at 14 in FIG. 2 and bearing on shims 15 applied against the vertical face 5 and the flange 8 of the mold base.

Il est préférable, pour des questions de tenue de l'ensemble, que les joues 3 aient une certaine épaisseur, du fait qu'elles sont en contact par leur tranche avec le fond de moule 1 et la maçonnerie 7 et qu'elles sont prises en sandwich et coincées entre eux. It is preferable, for reasons of holding the assembly, that the cheeks 3 have a certain thickness, because they are in contact by their edge with the mold base 1 and the masonry 7 and that they are taken sandwiched and wedged together.

Une fois le béton mis en place et sec, le coffrage s'enlève tout aussi facilement. Once the concrete is set and dry, the formwork can be removed just as easily.

Le coffre regingot 2 est d'abord retiré environ 2 heures après coulage du béton, puis sont exécutés les retours de regingot. Le lendemain l'ensemble fond de moule-joue peut être enlevé. The regingot 2 trunk is first removed approximately 2 hours after pouring the concrete, then the regingot returns are executed. The next day the bottom mold-cheek can be removed.

La forme et les dimensions des joues 3 et du fond de moule 1 peuvent bien entendu varier dans de larges mesures suivant les types de baies. The shape and dimensions of the cheeks 3 and of the mold base 1 can of course vary within wide limits depending on the types of berries.

Enfin, l'invention n'est évidemment pas limitée au mode de réalisation représenté et décrit ci-dessus mais en couvre au contraire toutes les variantes, notamment celles concernant les moyens assurant le coulissage guidé des joues le long du fond de moule et du coffre regingot.  Finally, the invention is obviously not limited to the embodiment shown and described above, but on the contrary covers all the variants, in particular those concerning the means ensuring the guided sliding of the cheeks along the bottom of the mold and of the trunk. gum.
