Abstract

Adjacent sheetings comprising, on their right-hand and left-hand ends, sections 4 shaped at their centre so as to define a space for allowing the placing of two parts 7 and 10 which are drilled with frustoconical holes 8, 11 constituting a female cone, then a slot 25 open at the lower portion of the parts 7, 10 and in the sections 4 allows the easy passage of a threaded rod 17 having at its free end a male truncated cone 18 prolonged by a manoeuvring square 19.

Description

On utilise très souvent, pour la coulée de murs en béton, des banches qui sont assemblées entre elles par un dispositif d'assemblage servant également à les aligner de façon à ce que celles-ci forment un plan aussi précis que possible afin d'obtenir une coulée correcte et, de ce fait, un mur en béton d'épaisseur constante. Very often, for the pouring of concrete walls, formwork which is joined together by an assembly device also serving to align them so that these form a plane as precise as possible in order to obtain correct pouring and, therefore, a concrete wall of constant thickness.

On connais déjà des dispositifs qui visent à assembler des banches contiguës, dispositif tendant àassurer également le centrage de ces banches en utilisant, d'une part, des paliers cylindriques et coniques percés dans des pièces de jonction fixées sur les ailes formant raidisseurs de banches et, d'autre part, des verrous en partie filetés avec des goupilles non récupérables formant point d'arrêt pour la parie conique mâle bloquée par vissage dans les ouvertures cylindriques et coniques des pièces de jonction solidaires des ailes formant raidisseurs des banches. There are already known devices which aim to assemble adjoining formwork, a device tending to also ensure the centering of these formwork using, on the one hand, cylindrical and conical bearings drilled in junction pieces fixed on the wings forming formwork stiffeners and , on the other hand, partially threaded locks with non-recoverable pins forming a stopping point for the conical male bet blocked by screwing in the cylindrical and conical openings of junction pieces integral with the wings forming stiffeners of the formwork.

Certaines banches nécessitent également en plus de dispositifs de verrouillage des pattes et des colliers disposés sur les raidisseurs contigus en alternance afin d'aligner les banches entre elles puis de relier ces banches par des verrous qui ne sont pas récupérables ou qui sont très souvent sans liaison directe avec la banche d'où, au moment du démontage, de grandes pertes d'organes de jonction. Some forms also require in addition to locking devices of the legs and collars arranged on the adjacent stiffeners alternately in order to align the forms between them and then to connect these forms by latches which are not recoverable or which are very often without connection direct with the panel from which, at the time of disassembly, great losses of junction members.

Tous ces dispositifs sont donc imparfaits es, si on y ajoute la nécessité de pièces traversantes maintenant la distance requise entre les banches placées de part et d'autre du mur après avoir ferraillé correctement, on est donc amené à utiliser
a) beaucoup de pièces plus ou moins parfaites ou eout au moins se détériorant très rapidement.
All these devices are therefore imperfect es, if we add the need for through pieces maintaining the required distance between the forms placed on either side of the wall after having correctly scrapped, we are therefore led to use
a) a lot of more or less perfect pieces or at least deteriorating very quickly.

b) pour la mise en place de cet ensemble des personnels hautement qualifiés et donc coûteux. b) for the establishment of this set of highly qualified and therefore costly personnel.

La présente invention remédie à ces inconvénients en utilisant un dispositif d'assemblage inamovible très résistant et pouvant être utilisé par du personnel non qualifié.  The present invention overcomes these drawbacks by using a very resistant, non-removable assembly device which can be used by unqualified personnel.

Conformément à l'invention, le dispositif est consti- tué par des banches adjacentes comportant sur leurs extrémités droite ee gauche des profilés conformés en leur cen tre pour délimiter un espace pour permettre la mise en place de deux pièces percées de trous tronconiques constituant un cône femelle, puis une fenêtre ouverte à la partie inférieure des pièces es dans les profilés permet le passage aisé d'une sige filets présentant à son extrémité libre un tronc de cône mâle prolongé par un carré de manoeuvre , la tige filetée coopérant avec un canal taraudé percé dans la base d'une pièce en U articulée sur un axe d'une patte fixée sur le profilé de gauche de chaque banche afin de permettre, par pivotement de la pièce en U à travers la fenêtre, la mise en place du tronc de cône de cote légèrement inférieure aux cotes du trou tronconi- que afin de réaliser, en utilisant un dispositif de fixa ilion haut et un dispositif de fixation bas, une liaison facile à manoeuvrer et permettant un alignement correct des deux banches adjacentes assemblées de manière contiguë. According to the invention, the device is constituted by adjacent forms having on their right and left ends profiles shaped in their center to delimit a space to allow the installation of two parts pierced with frustoconical holes constituting a cone female, then a window open at the bottom of the parts is in the profiles allows the easy passage of a threaded seat having at its free end a male truncated cone extended by a maneuvering square, the threaded rod cooperating with a threaded channel drilled in the base of a U-shaped piece articulated on an axis of a lug fixed on the left profile of each form to allow, by pivoting the U-shaped piece through the window, the establishment of the trunk of cone with a dimension slightly lower than the dimensions of the frustoconical hole in order to achieve, by using a high fixing device and a low fixing device, an easy-to-maneuver connection allowing an al correct igniting of the two adjacent formwork assembled in a contiguous manner.

Diverses autres caractéristiques de l'invention ressortent d'ailleurs de la description détaillée qui suit. Various other characteristics of the invention will also emerge from the detailed description which follows.

Une forme de réalisation de l'objet de l'invention est représentée, à titre d'exemple non limitatif, au dessein annexé. An embodiment of the object of the invention is shown, by way of nonlimiting example, in the appended drawing.

La fig. 1 est une coupe en plan montrant la jonction de deux banches contiguës. Fig. 1 is a plan section showing the junction of two adjoining forms.

La fig. 2 est une coupe suivant la ligne II-II de la fig. 1.  Fig. 2 is a section along line II-II of FIG. 1.

La fig. 3 est une vue de face suivant la flèche FIII de la fig. 2. Fig. 3 is a front view along arrow FIII of FIG. 2.

La fig. 4 est une coupe analogue à la fig. 2 dans une autre position de fonctionnement. Fig. 4 is a section similar to FIG. 2 in another operating position.

A la fig. 1, on a représenté deux parties de banches adjacentes 1, 2 raidies par des profilés verticaux 3 sensi blement en U.  In fig. 1, two parts of adjacent forms 1, 2 are shown stiffened by vertical sections 3 substantially in a U shape.

Des profilés 4 sensiblement en I sont fixés par leurs pieds 4a sur le bord la, 2a des banches 1, 2. Ces profilés verticaux 4 comportent en leur milieu une déformation lon gitudinale 5 qui forme, lorsque deux banches sont voisines, un espace 6. Finalement, les profilés 4 se terminent par des parties redressées 4b. Profiles 4 substantially in I are fixed by their feet 4a to the edge 1a, 2a of the forms 1, 2. These vertical profiles 4 comprise in their middle a longitudinal deformation 5 which forms, when two forms are adjacent, a space 6. Finally, the sections 4 end in straightened parts 4b.

Les extrémités droites des banches portent, fixées par soudure , sur les profilés 4 des pièces 7 de forme sensiblement parallélépipèdique rectangle percées en leur centre d'un trou tronconique 8 (Fig. 2). De même, les profilés 4 des parties gauches des banches, qui doivent donc venir sur les profilés 4 de la banche adjacente, comportens des pièces 10 percées en leur centre d'un trou tronconique 11 de plus petit diamètre que le trou 8 de la pièce 7. Les profilés 4 gauches portent également une pat- se 12 maintenant un axe 13 sur lequel peut pivoter une pièce 14 en U dont la base 15 est percée d'un canal taraudé 16 destiné à recevoir une tige filetée 17 d'une certaine longueur qui se termine à son extrémité 17a (voir fig.4) par un tronc de cône 18 et un carré 19 percé de deux trous ortogonaux 20, 21.De plus, les deux profilés 4 sont percés, sous les pièces 7 et 10, d'une fenêtre 25 permettant le passage aisé de la tige filetée 17 prolongée par le tronc de cane 18 et le carré 19. The straight ends of the forms bear, fixed by welding, on the profiles 4 of the parts 7 of substantially rectangular parallelepiped shape pierced in their center with a frustoconical hole 8 (Fig. 2). Likewise, the sections 4 of the left-hand parts of the forms, which must therefore come onto the sections 4 of the adjacent form, include parts 10 pierced in their center with a frustoconical hole 11 of smaller diameter than the hole 8 in the part 7. The left-hand profiles 4 also carry a strap 12 holding an axis 13 on which a U-shaped part 14 can pivot, the base 15 of which is pierced by a tapped channel 16 intended to receive a threaded rod 17 of a certain length which ends at its end 17a (see fig. 4) with a truncated cone 18 and a square 19 pierced with two orthogonal holes 20, 21. Furthermore, the two sections 4 are pierced, under the parts 7 and 10, d a window 25 allowing the easy passage of the threaded rod 17 extended by the cane trunk 18 and the square 19.

Le dispositif d'assemblage formant verrou auto-aligneur fonctionne de la façon suivante. The assembly device forming a self-aligning lock operates as follows.

Lorsque les deux banches (voir fig. 4) sont alignées sensiblement dans leur prolongemens , la tige 17 considérée est amenée de la position représentée i la fig. 4 à la position représentée à la fig. 2. When the two forms (see fig. 4) are aligned substantially in their extension, the rod 17 considered is brought from the position shown in fig. 4 in the position shown in FIG. 2.

On visse, soit à l'aide du carré 19, soit à l'aide d'un des trous 20, 21, la tige filetée 17 dans le canal taraudé 16 de la base 15 de la pièce 14 en U afin que le tronc de cône 18 pénètre dans les trous tronconiques 8 et 11 des pièces 7 et 10 en assurant ainsi le resserrage des profilés 4 les uns contre les autres deux à deux (fig.l) et en même temps un alignement correct des deux banches contiguës l'une par rapport à l'autre. Ceci est rendu possible du fait que le tronc de cône femelle 8, 11 est légè remuent plus évasé que le tronc de cone mâle 18. We screw, either using the square 19, or using one of the holes 20, 21, the threaded rod 17 in the threaded channel 16 of the base 15 of the U-shaped part 14 so that the trunk of cone 18 penetrates into the frustoconical holes 8 and 11 of the parts 7 and 10 thereby ensuring the tightening of the profiles 4 against each other two by two (fig.l) and at the same time a correct alignment of the two adjoining forms compared to each other. This is made possible by the fact that the female cone trunk 8, 11 is slightly stirred more flared than the male cone trunk 18.

Lorsqu'on se trouve en fin de vissage, il se produit un très bon blocage, et comme ces dispositifs sont au moins au nombre de deux par extrémité des banches l'un en haut l'autre en bas, les banches sont placées dans un même plan avec le minimum de différences d'affleurements entre elles. When you are at the end of the screwing, there is a very good blocking, and as these devices are at least two in number per end of the formwork, one at the top the other at the bottom, the forms are placed in a same shot with the minimum of outcrop differences between them.

I1 vient d'être décris le montage du dispositif, le démontage s'effectuant par une manipulation inverse. I1 has just been described the assembly of the device, disassembly being effected by reverse manipulation.

Ainsi, la conjugaison de cônes échancrés et à surface intérieure non alignée avant serrage, avec conire-cônes amovibles et insérables dans les cônes échancrés, consti- tue un système auto-aligneur inamovible original. Thus, the combination of scalloped cones and non-aligned interior surface before tightening, with cone-cones removable and insertable into the scalloped cones, constitutes an original non-removable self-aligning system.

Bien entendu, de l'autre côté de la zone de coffrage sont placées d'autres banches B10 (voir fig. 1), banches montées de la même façon que les précédentes et reliées à ces dernières par des pièces raidissantes d'une manière connue en soi.  Of course, on the other side of the formwork area are placed other formwork B10 (see fig. 1), formwork mounted in the same way as the previous ones and connected to the latter by stiffening parts in a known manner in itself.
