Description
On sait qu'il est difficile d'assembler rapidement et avec précision sur les chantiers des panneaux appelés banches servant à faire des moules où le béton est coulé. We know that it is difficult to quickly and precisely assemble panels on worksites called formwork used to make molds where concrete is poured.
Les difficultés proviennent du fait que les banches sont souvent très lourdes et qu'il faut manipuler ces panneaux avec des engins de levage pour les juxtaposer deux à deux. Naturellement la juxtaposition avant assemblage est déjà difficile à réaliser car les banches suspendues à un engin de levage ne restent pas immobiles. L'assemblage se fait dans la plupart des cas soit par boulons, soit pas broches à clavette et on comprend qu'il est souvent difficile de mettre en alignement les trous pratiqués dans les embouts, c'est-à-dire les bords des banches redressés à angle droit, d'autant plus que le diamètre des trous ne permet par de jeu. The difficulties arise from the fact that the forms are often very heavy and that these panels have to be handled with lifting devices in order to juxtapose them two by two. Naturally the juxtaposition before assembly is already difficult to achieve because the forms suspended from a lifting machine do not remain stationary. The assembly is done in most cases either by bolts or not key pins and we understand that it is often difficult to align the holes in the end pieces, that is to say the edges of the formwork straightened at right angles, especially since the diameter of the holes does not allow any play.
D'ailleurs il y a encore un autre inconvénient que présentent les boulons ou les broches à clavettes. Le filetage des boulons est détérioré rapidement par le béton et pour enfoncer les clavettes et les enlever il faut frapper énergiquement avec un marteau, ce qui détériore encore plus les clavettes et les broches. De plus ces accessoires se perdent rapidement sur les chantiers. Besides, there is yet another drawback which the bolts or the key pins have. The threads of the bolts are quickly deteriorated by the concrete and to drive in the keys and remove them, you have to strike hard with a hammer, which further deteriorates the keys and pins. In addition, these accessories are quickly lost on construction sites.
Le but de l'invention est de réaliser un dispositif qui remédie totalement à tous ces inconvénients. The object of the invention is to provide a device which completely remedies all these drawbacks.
A cet effet l'invention a pour objet un dispositif d'accouplement de banches et analogues caractérisé en ce qu'il est constitué essentiellement d'une part par deux embases d'entrée et de sortie. solidarisées avec les embouts de deux banches à accoupler, chaque embase présentant un forage conique en prolongement l'un de l'autre, et d'autre part par un élément conique mâle prolongé par une vis pourvue d'une tête à oeil, élément mâle qui tient alignées de façon parfaite les deux embases qprès son introduction dans celles-ci, cet élément présentant des moyens de blocage, tandis que l'embase de sortie présente des trous pouvant coincider avec ceux de la tête à oeil pour recevoir une broche à clavette. To this end the invention relates to a formwork coupling device and the like characterized in that it consists essentially on the one hand by two inlet and outlet bases. secured to the end caps of two rods to be coupled, each base having a conical bore in extension of one another, and on the other hand by a male conical element extended by a screw provided with an eye head, male element which keeps the two bases perfectly aligned after its introduction therein, this element having locking means, while the outlet base has holes which can coincide with those of the eye head for receiving a key pin .
Ce dispositif d'accouplement peut, en outre, présenter une ou plusieurs des caractéristiques suivantes. This coupling device can also have one or more of the following characteristics.

e - les moyens de blocage de l'élément mâle dans les forages coniques sont constitués par des trous dans l'élément mâle placés et dimensionnés pour recevoir une broche permettant d'effectuer le serrage jusqu'au blocage. e - the means for blocking the male element in the conical boreholes consist of holes in the male element placed and dimensioned to receive a pin enabling tightening to be carried out until blocking.
g - lesdits moyens de blocage sont constitués par un six pans sur l'élément mâle. g - said blocking means consist of a hexagon on the male element.
Afin de mieux faire comprendre l'invention on en décrira ci-dessous un mode de réalisation en se référant aux dessins annexés, dans lesquels

Le dispositif d'accouplement comprend essentiellement après fixation, par exemple par soudage, sur les embouts 1 et 2 de deux banches 3 et 4, deux embases 5, 7 et un élément conique mâle 11. The coupling device essentially comprises, after fixing, for example by welding, to the end pieces 1 and 2 of two forms 3 and 4, two bases 5, 7 and a male conical element 11.
L'embase 5 a été fixée sur l'embout 1 et l'embase de sortie 7 sur l'embout 2. L'embase 5 présente un forage conique 6 et l'embase 7 un forage conique 8. I1 faut noter que l'orifice d'entrée du forage 6 a un diamètre relativement important. L'embase d'entrée 5 présente une gorge circulaire 9, tandis que sur l'embase de sortie 7 ont été pratiqués des trous 10 diamètralement opposés. The base 5 has been fixed on the end piece 1 and the outlet base 7 on the end piece 2. The base 5 has a conical bore 6 and the base 7 a conical bore 8. It should be noted that the borehole inlet 6 has a relatively large diameter. The inlet base 5 has a circular groove 9, while on the outlet base 7 are holes 10 diametrically opposite.
Les deux embases représentées sur les figures I et 2 sont réunies après rapprochement (Fig. 3) par un élément male 11. Celui-ci comporte une partie conique 12 filetée intérieurement précédée par une partie cylindrique 13. La partie conique est dimensionnée pour s'adapter, après enfoncement dans les forages 6 et 8, au profil de ces derniers, et le forage 6 est suffisamment grand pour laisser un jeu très important à la partie conique 12 de l'élément 11. Enfin l'élé- ment 11 présente une gorge circulaire 14, une série de trous 15 diamétralement opposés deux à deux pour recevoir une broche de commande, non représentée et un trou 16 qui servira à placer une clavette de retenue 17 (Fig. 1) commeon le verra plus loin. The two bases shown in Figures I and 2 are joined after approximation (Fig. 3) by a male element 11. This comprises a conical part 12 internally threaded preceded by a cylindrical part 13. The conical part is sized to s' adapt, after being inserted into the holes 6 and 8, to the profile of the latter, and the hole 6 is large enough to leave a very large clearance to the conical part 12 of the element 11. Finally, the element 11 has a circular groove 14, a series of holes 15 diametrically opposite two by two to receive a control pin, not shown and a hole 16 which will serve to place a retaining key 17 (Fig. 1) as will be seen later.
Le filetage intérieur de la partie conique 12 coopère avec une vis 18 pourvue d'une tête à oeil 19 de sorte que sa partie conique 12 est prolongée par cette tête à oeil comme on le voit sur la Fig. 3. Une broche à clavette 20 est prévue pour être introduite dans les trous 10 de l'embase de sortie et le fors 21 de la tête à oeil après qu'ils ont été alignés, une goupille mecanindus 22 sur la broche 20 empêchant qu'elle se détache du dispositif et se perde. The internal thread of the conical part 12 cooperates with a screw 18 provided with an eye head 19 so that its conical part 12 is extended by this eye head as seen in FIG. 3. A key pin 20 is provided to be introduced into the holes 10 of the outlet base and the fors 21 of the eye head after they have been aligned, a mechanical pin 22 on the pin 20 preventing that it detaches from the device and gets lost.
D'autre part l'élément 11 est aussi pourvu de moyens pourqu'il ne se détache pas du dispositif. Ces moyens sont constitués par un ressort en spirale 23 dont la spirale extrême 24 est conformée pour embrasser la gorge circulaire
9 de l'embase d'entrée 5 tandis que la spirale extrême 25, plus petite, est conformée pour embrasser la gorge circulaire 14 de l'élément conique 11.On the other hand the element 11 is also provided with means so that it does not detach from the device. These means are constituted by a spiral spring 23, the extreme spiral 24 of which is shaped to embrace the circular groove
9 of the inlet base 5 while the smaller end spiral 25 is shaped to embrace the circular groove 14 of the conical element 11.
Les figures 3 et 4 montrent le dispositif en position de service après introduction de l'élément conique dans les forages coniques qui avaient été alignés approximativement au préalable. Avant l'introduction dans l'embase, la visl8 (Fig. 2) avait été vissée dans le filetage intérieur de la partie conique 12. Elle est maintenue par mesure de sécurité, par la clavette 17 (Fig. 1) insérée en passant par le trou 16 de l'élément 11 dans le forage 16a de la vis 18. Après l'introduction de l'élément 11 dans les forages le blocage de l'ensemble est effectué en tournant jusqu'au blocage l'élément 11 au moyen d'une broche, non représentée, insérée dans les trous 15.
De l'autre côté du dispositif, derrière l'embout 2, le dispositif est retenu par la broche à clavette 14 insérée dans les trous 10 de l'embase 7 après alignement du forage 21 de la tête à oeil 19 avec eux.La sécurité du blocage est donc absolue.Figures 3 and 4 show the device in the service position after introduction of the conical element in the conical holes which had been aligned approximately beforehand. Before insertion into the base, the screw 18 (Fig. 2) had been screwed into the internal thread of the conical part 12. It is held for safety, by the key 17 (Fig. 1) inserted passing through the hole 16 of the element 11 in the drilling 16a of the screw 18. After the introduction of the element 11 in the boreholes the blocking of the assembly is carried out by turning until the blocking of the element 11 by means of 'a pin, not shown, inserted in the holes 15.
On the other side of the device, behind the end piece 2, the device is retained by the key pin 14 inserted in the holes 10 of the base 7 after alignment of the bore 21 of the eye head 19 with them. blocking is therefore absolute.
D'autre part, après démontage l'élément mâle 11 reste attaché à l'embout de banche 5 par le ressort 23, comme on le voit sur la Fig. 5, et la broche à clavette reste attachée à l'embout de banche 7 grâce à la goupille mecanindus 22. On the other hand, after dismantling the male element 11 remains attached to the end piece 5 by the spring 23, as seen in FIG. 5, and the key pin remains attached to the end piece 7 thanks to the mecanindus pin 22.
Les avantages du dispositif selon l'invention sont extrêmement importants. The advantages of the device according to the invention are extremely important.
Le fait que les forages dans les embases sont coniques permet l'introduction aisée de l'élément mâl-e avec un jeu considérable, l'élément mâle alignant ensuite automatiquement les deux parties coniques. L'introduction de l'élément mâle est donc immédiate et ne présente aucune difficulté. The fact that the holes in the bases are conical allows easy insertion of the male element with considerable play, the male element then automatically aligning the two conical parts. The introduction of the male element is therefore immediate and presents no difficulty.
Jusqu'ici le fait que les trous étaient cylindriques apportait des difficultés très importantes pour introduire les broches d'alignement ou les boulons. Heretofore, the fact that the holes were cylindrical has brought great difficulty in introducing the alignment pins or bolts.
En outre le fait que la broche à clavette soit imperdable et que l'élément conique reste attaché à sa banche est sur les chantiers un avantage considérable que lton n'avait pas obtenu jusqu'ici. In addition, the fact that the key pin is captive and that the conical element remains attached to its form is on construction sites a considerable advantage that lton had not obtained so far.
Il va de soi que le dispositif d'accouplement de banches suivant l'invention peut être utilisé pour accoupler des tôles, profilés et autres éléments analogues. It goes without saying that the formwork coupling device according to the invention can be used to couple sheets, profiles and other similar elements.
