Description

La présente invention concerne le domaine de l'industrie du bâtiment et des travaux publics, en particulier le domaine de la fabrication de matériels de chantiers et notamment des banches pour la réalisation de murs ou de voiles, et a pour objet un dispositif d'assemblage des rives verticales de telles banches.The present invention relates to the field of the construction industry and public works, in particular the field of the manufacture of construction site materials and in particular the panels for the production of walls or sails, and relates to an assembly device vertical banks of such banches.

Actuellement, le coffrage de murs est généralement effectué au moyen de banches qui sont constituées par une surface de coffrage proprement dite, par des moyens d'appui au sol et de réglage de la verticalité et par des moyens d'assemblage de banches voisines entre elles, ces banches étant pourvues, en outre, de dispositifs annexes de sécurité, tels que des plateformes de circulation, les divers éléments constitutifs étant assemblés par l'intermédiaire de boulons ou de broches.Currently, the wall formwork is generally carried out by means of panels which are constituted by a formwork surface proper, by ground support means and verticality adjustment and by means of assembling adjoining banches them , these panels being further provided with additional safety devices, such as traffic platforms, the various components being assembled by means of bolts or pins.

Les faces coffrantes des banches et tables connues sont réalisées, soit en une tôle soudée sur l'infrastructure de support et d'étaiement, soit en panneaux contreplaqués vissés sur ladite infrastructure. De telles banches sont notamment décrites dans FR-A-2 470 220 et FR-A-2 598 453 . Il a également été proposé, dans des réalisations récentes, d'équiper les banches de faces coffrantes en matériau composite stratifié ou pultrudé (voir EP-A1 413 696 ).The formwork faces of known panels and tables are made either of a welded sheet on the support and shoring infrastructure, or of plywood panels screwed onto said infrastructure. Such banches are described in particular in FR-A-2,470,220 and FR-A-2,598,453 . It has also been proposed, in recent achievements, to equip the panels with formwork faces made of laminated or pultruded composite material (see FIG. EP-A1 413 696 ).

Ces banches connues permettent, généralement, de remplir correctement leur fonction, à savoir de coffrage de murs ou analogues présentant un bon état de surface et leurs dispositifs annexes de réglage et d'assemblage, ainsi que de sécurité remplissent également leur rôle de manière satisfaisante.These known panels allow, generally, to properly perform their function, namely formwork walls or the like having a good surface and their ancillary devices for adjustment and assembly, as well as safety also perform their role satisfactorily.

Ainsi, les moyens d'assemblage des banches entre elles, en particulier des rives verticales permettent, par mise en oeuvre d'ensembles vis-écrous à manchon de centrage tronconique, l'obtention d'un bon affleurement des faces coffrantes et un serrage correct des rives entre elles.Thus, the means for assembling the panels together, in particular vertical edges, by means of screw-nut assemblies with a frustoconical centering sleeve, make it possible to obtain a good flush of the formwork faces and a correct clamping. shores between them.

Cependant, la mise en oeuvre de tels ensembles à centrage conique et à serrage par vis et écrous, connus notamment par FR-A-2 470 220 , présente l'inconvénient d'une trop grande rigidité du centrage conique, de sorte que le positionnement préalable de banches voisines doit être effectué avec une précision de positionnement relativement grande, ce qui entraîne des pertes de temps correspondantes. En outre, un centrage conique est souvent relativement fragile et les ensembles vis et écrous mis en oeuvre présentent un pas relativement faible, à savoir de l'ordre de 5 millimètres, ce qui entraîne des temps de manoeuvre plus long, le vissage de l'ensemble s'effectuant relativement lentement.However, the implementation of such conical centering assemblies and clamping by screws and nuts, known in particular by FR-A-2,470,220 , has the disadvantage of too much stiffness conical centering, so that the prior positioning of neighboring banches must be performed with a relatively high positioning accuracy, resulting in corresponding time losses. In addition, a conical centering is often relatively fragile and screw and nut assemblies used have a relatively small pitch, namely of the order of 5 millimeters, which results in longer operating times, the screwing of the together relatively slowly.

La présente invention a pour but de pallier ces inconvénients en proposant un dispositif d'assemblage des rives verticales de banches permettant d'effectuer de manière sûre et rapide un assemblage de banches voisines avec un alignement et un affleurement parfait entre lesdites banches.The present invention aims to overcome these drawbacks by proposing a device for assembling the vertical banks of docks to perform safely and quickly an assembly of neighboring banquettes with alignment and a perfect outcrop between said dams.

A cet effet, le dispositif d'assemblage des rives verticales de banches entre elles, qui est essentiellement constitué par des paires de boîtiers mâle et femelle insérés chacun en opposition dans une rive verticale de deux banches accolées par lesdites rives verticales et comportant respectivement une vis et un écrou, la vis coopérant avec une douille de guidage correspondante du boîtier et avec un moyen de retenue de la vis en position de non utilisation, tandis que l'écrou est maintenu en position de non utilisation dans le boîtier par l'intermédiaire d'un moyen de retenue, est caractérisé en ce que les ensembles vis-écrou de chaque paire de boîtiers se présentent sous forme de moyens de liaison à centrage et à guidage cylindriques, la vis étant constituée par une broche, filetée à une extrémité, sur laquelle est prévu un manchon étagé de précentrage et de centrage et qui est prolongée, du côté du manchon étagé opposé au filetage, par un moyen de manoeuvre.For this purpose, the device for assembling the vertical banks of panels between them, which consists essentially of pairs of male and female housings each inserted in opposition in a vertical bank of two banks joined by said vertical banks and respectively comprising a screw and a nut, the screw cooperating with a corresponding guide bushing of the housing and with a means for retaining the screw in the non-use position, while the nut is held in the non-use position in the housing via a retaining means is characterized in that the screw-nut assemblies of each pair of housings are in the form of cylindrical centering and guiding connection means, the screw being constituted by a pin, threaded at one end, on which is provided a stepped sleeve pre-centering and centering and which is extended, on the opposite side of the stepped sleeve to the thread, by a means of my noeuvre.

Conformément à l'invention, les ensembles vis 21-écrou 31 de chaque paire de boîtiers 2 et 3 se présentent sous forme de moyens de liaison à centrage et à guidage cylindriques, la vis 21 étant avantageusement constituée par une broche 21', filetée à une extrémité, sur laquelle est prévu un manchon étagé de précentrage et de centrage 21", et qui est prolongée, du côté du manchon étagé 21" opposé au filetage, par un moyen de manoeuvre 21"'.According to the invention, the screw 21-nut 31 assemblies of each pair of housings 2 and 3 are in the form of cylindrical centering and guide connection means, the screw 21 being advantageously constituted by a pin 21 ', threaded at one end, on which is provided a stepped sleeve pre-centering and centering 21 ", and which is extended, on the side of the stepped sleeve 21" opposite the thread, by an operating means 21 "'.

De préférence, la deuxième partie 211" comporte plusieurs méplats 2111" répartis à intervalles réguliers sur sa périphérie et, notamment, trois méplats 2111 ". De tels méplats sont destinés à réaliser un dégagement automatique du béton pouvant s'être infiltré dans le dispositif d'assemblage des rives, lors du coulage du béton entre les banches.The stepped pre-centering and centering sleeve 21 "is advantageously integral with the pin 21 'and is subdivided respectively into a first portion 210" of diameter slightly greater than that of the end threaded portion 21' and a second portion 211 " of greater diameter than that of the first portion 210 "connected to the first portion 210" by a chamfer having at least one flat 2111 "and provided at its end opposite the first portion 210" of a shoulder 2112 ", this second portion 211 "being intended to cooperate with the corresponding guide bushing 22 of the housing 2 of the screw 21. Preferably, the second portion 211" has several flats 2111 "distributed at regular intervals on its periphery and, in particular, three flats 2111 ". Such flats are intended to achieve an automatic release of concrete that may have infiltrated into the assembly device of the banks, during the pouring of concrete between the panels.

Le moyen de manoeuvre 21"', prolongeant la broche 21' du côté du manchon étagé 21" opposé au filetage, est reliée audit côté du manchon étagé 21" par l'intermédiaire d'un palier 210', prolongeant l'épaulement 2112", de plus faible diamètre que ce dernier et de dimension plus faible que celle du moyen de manoeuvre 21"', ce palier 210' étant destiné à la réception, à rotation libre, d'une patte de liaison 5 coopérant avec le moyen de retenue 23 de la vis 21.The operating means 21 "', extending the pin 21' on the side of the stepped sleeve 21" opposite to the thread, is connected to the said side of the stepped sleeve 21 "via a bearing 210 ', extending the shoulder 2112" , of smaller diameter than the latter and of smaller dimension than that of the operating means 21 "', this bearing 210' being intended for the receiving, free rotation, a connecting lug 5 cooperating with the retaining means 23 of the screw 21.

Ce moyen 23 de retenue de la vis 21 se présente avantageusement sous forme d'un axe longitudinal, s'étendant sensiblement parallèlement à l'axe de la vis 21 en position de service et sur lequel la patte de liaison 5 est guidée en translation. Ainsi, la vis 21 peut être déplacée en translation par rapport à la rive de la banche 1 ou 1' qu'elle équipe, tout en pouvant être mise en rotation autour de son axe longitudinal.This means 23 for retaining the screw 21 is advantageously in the form of a longitudinal axis, extending substantially parallel to the axis of the screw 21 in the operating position and on which the connecting lug 5 is guided in translation. Thus, the screw 21 can be displaced in translation relative to the side of the panel 1 or 1 'that it equips, while being able to be rotated about its longitudinal axis.

L'axe longitudinal formant le moyen de retenue 23 de la vis 21 est préférentiellement constitué par une tige métallique montée à une extrémité dans le bord correspondant du boîtier 2 et maintenue à son autre extrémité dans une platine 6 solidaire de l'infrastructure de la banche 1 ou 1', le montage de cet axe pouvant être réalisé par mise en oeuvre de bagues de maintien ou analogues ou encore d'un moyen de blocage par vissage. En effet, cet axe peut, par exemple, être inséré à une extrémité dans un perçage correspondant du boîtier 2 et son maintien en translation peut être assuré par mise en oeuvre de bagues de maintien du type circlips ou analogues, ou encore d'un dispositif de blocage de l'axe, solidarisé avec la platine 6.The longitudinal axis forming the retaining means 23 of the screw 21 is preferably constituted by a metal rod mounted at one end in the corresponding edge of the housing 2 and held at its other end in a plate 6 integral with the infrastructure of the form 1 or 1 ', the mounting of this axis can be achieved by implementation of retaining rings or the like or a locking means by screwing. Indeed, this axis can, for example, be inserted at one end into a corresponding bore of the housing 2 and its translation retention can be ensured by implementation retaining rings of the circlip or similar type, or a device locking the shaft, secured to the plate 6.

Le moyen de manoeuvre 21'" se présente préférentiellement sous forme d'un polygone de manoeuvre, emboîté avec coopération de forme sur un embout polygonal 211"', prévu au centre du palier 210', et fixé à cet embout polygonal 211"' par l'intermédiaire d'une goupille 211"". Un tel montage du moyen de manoeuvre 21'" permet une dissociation des éléments fonctionnels de la vis 21 entre les parties ayant des fonctions d'assemblage de précision et les parties servant uniquement à la manoeuvre et au maintien de la vis.The operating means 21 '' is preferably in the form of a maneuvering polygon, fitted with shape cooperation on a polygonal bit 211 "', provided in the center of the bearing 210', and fixed to this polygonal end piece 211" 'by by means of a pin 211 "" Such an assembly of the operating means 21 '"allows a dissociation of the functional elements of the screw 21 between the parts having precision assembly functions and the parts serving only for the maneuver and maintaining the screw.

En effet, la broche filetée 21' et le manchon étagé 21" peuvent ainsi être réalisés en un acier noble ou ayant subi un traitement de surface particulier en vue de l'amélioration du coefficient de frottement et/ou des caractéristiques mécaniques, ainsi que de résistance à la corrosion, alors que le moyen de manoeuvre 21'" et le moyen de retenue 23 peuvent être réalisés en un acier de moindre coût.Indeed, the threaded spindle 21 'and the stepped sleeve 21 "can thus be made of a noble steel or having undergone a particular surface treatment with a view to improving the coefficient of friction and / or the mechanical characteristics, as well as resistance to corrosion, while the operating means 21 '"and the retaining means 23 can be made of a lower cost steel.

Selon une autre caractéristique de l'invention, le polygone de manoeuvre 21'" peut avantageusement être pourvu à son extrémité distale d'une poignée de manoeuvre 21"". Une telle poignée de manoeuvre 21"" permet de réaliser un premier serrage de la vis 21 dans l'écrou 31 et notamment l'approche et l'introduction initiale de la vis 21, en favorisant sa préhension et sa manoeuvre manuelle.According to another characteristic of the invention, the maneuvering polygon 21 "may advantageously be provided at its distal end with an operating handle 21". Such a maneuvering handle 21 "" makes it possible to perform a first tightening of the screw 21 in the nut 31 and in particular the approach and the initial introduction of the screw 21, by promoting its grip and its manual operation.

La figure 4 des dessins annexés représente une variante de réalisation de l'invention, dans laquelle le manchon étagé de précentrage et de centrage 21" est avantageusement solidaire de la broche 21' en translation et libre en rotation. Afin de permettre une meilleure compréhension de la description de ce mode de réalisation, les mêmes éléments fonctionnels de la broche 21' et du manchon étagé de précentrage et de centrage 21" de la vis 21 sont désignés par les mêmes références augmentées de 10000.FIG. 4 of the accompanying drawings shows an alternative embodiment of the invention, in which the staggered precentering and centering sleeve 21 "is advantageously secured to the spindle 21 'in translation and free to rotate in order to allow a better understanding of the description of this embodiment, the same functional elements of the pin 21 'and stepped sleeve pre-centering and centering 21 "of the screw 21 are designated by the same references increased by 10000.

Comme le montre la figure 4 des dessins annexés, le manchon étagé de précentrage et de centrage 21" est subdivisé respectivement en une première partie 10210" de diamètre légèrement supérieur à celui de la partie filetée d'extrémité 21' et en une deuxième partie 10211", de diamètre supérieur à celui de la première partie 10210", reliée à la première partie 10210" par un chanfrein, comportant au moins un méplat 12111" et pourvue à son extrémité opposée à la première partie 10210" d'un épaulement 12112", cette deuxième partie 10211" étant destinée à coopérer avec la douille de guidage correspondante 22 du boîtier 2 de la vis 21. De préférence, la deuxième partie 10211" comporte plusieurs méplats 12111" répartis à intervalles réguliers sur sa périphérie et, notamment, trois méplats 12111". De tels méplats sont destinés à réaliser un dégagement automatique du béton pouvant s'être infiltré dans le dispositif d'assemblage des rives, lors du coulage du béton entre les banches.As shown in FIG. 4 of the accompanying drawings, the preassembled centering and centering sleeve 21 "is subdivided respectively into a first portion 10210" of diameter slightly greater than that of the end threaded portion 21 'and a second portion 10211 "of greater diameter than that of the first portion 10210" connected to the first portion 10210 "by a bevel, having at least one flattened portion 12111" and provided at its opposite end to the first portion 10210 "of a shoulder 12112" , this second portion 10211 "being intended to cooperate with the corresponding guide bushing 22 of the housing 2 of the screw 21. Preferably, the second portion 10211" comprises several flats 12111 "distributed at regular intervals on its periphery and, in particular, three flats 12111 ". Such flats are intended to achieve an automatic release of concrete that may have infiltrated into the assembly device of the banks, during the pouring of concrete between the panels.

Par ailleurs, du côté sortant du manchon étagé de précentrage et de centrage 21", opposé au filetage, la broche 21' peut avantageusement être pourvue d'un moyen de manoeuvre 21"' sous forme d'un polygone de manoeuvre 21"', ce dernier étant éventuellement muni à son extrémité distale d'une poignée de manoeuvre 21"". Le polygone de manoeuvre 21"', muni ou non d'une poignée de manoeuvre 21"", peut être d'une seule pièce avec la broche filetée 21' ou être rapporté sur cette dernière par l'intermédiaire d'un montage à emboîtement et à goupille tel que celui décrit en regard du mode de réalisation suivant les figures 1 à 3 des dessins annexés.On the other hand, on the outgoing side of the stepped pre-centering and centering sleeve 21 ", opposite to the threading, the spindle 21 'can advantageously be provided with an operating means 21" in the form of a maneuvering polygon 21 "'. the latter possibly being provided at its distal end with a maneuvering handle 21 ". The operating polygon 21" ', provided or not with an operating handle 21 "", can be in one piece with the spindle threaded 21 'or be attached thereto via an interlocking fitting and pin such as that described with respect to the embodiment according to Figures 1 to 3 of the accompanying drawings.

Le maintien du manchon étagé de précentrage et de centrage 21" sur la broche 21' est assuré par prévision d'une partie épaulée 10210' d'appui de l'épaulement 12112", au droit du polygone de manoeuvre 21'" et par une bague de maintien 4 coopérant avec une gorge circulaire 10211' prévue à l'extrémité de la partie filetée de la broche 21', la distance entre la partie épaulée 10210' et la bague de maintien 4 coopérant avec la gorge annulaire 10211" étant légèrement supérieure à la longueur du manchon étagé 21 ". Ainsi, le manchon étagé présente un léger degré de liberté en translation permettant d'assurer un fonctionnement parfait de la vis 21.Maintaining the stepped pre-centering and centering sleeve 21 "on the pin 21 'is provided by providing a shouldered shoulder portion 10210' of the shoulder 12112", at the right of the maneuvering polygon 21 '"and by a holding ring 4 cooperating with a circular groove 10211 'provided at the end of the threaded portion of the pin 21', the distance between the shoulder portion 10210 'and the holding ring 4 cooperating with the annular groove 10211 "being slightly greater than the length of the stepped sleeve 21 ". Thus, the stepped sleeve has a slight degree of freedom in translation to ensure perfect operation of the screw 21.

En outre, la partie épaulée 10210" de l'épaulement 12112" forme un palier de réception, à rotation libre, d'une patte de liaison 5 coopérant avec le moyen de retenue 23 de la vis 21. Ce moyen 23 de retenue de la vis 21 est avantageusement identique à celui décrit à propos du mode de réalisation selon les figures 1 à 3 et n'est pas décrit plus en détail.In addition, the shouldered portion 10210 "of the shoulder 12112" forms a receiving bearing, free rotation, a connecting lug 5 cooperating with the retaining means 23 of the screw 21. This means 23 for retaining the screw 21 is advantageously identical to that described with regard to the embodiment according to FIGS. 1 to 3 and is not described in more detail.

L'écrou 31 est un écrou flottant interchangeable présentant une partie taraudée 311, ayant une face 311' d'appui contre un manchon de guidage 3' du boîtier 3, et une partie de maintien en rotation et de guidage en translation 312 coopérant avec le moyen de retenue 33 dudit boîtier 3, la jonction entre la partie taraudée 311 et la partie de maintien en rotation et de guidage en translation 312 étant réalisée sous forme d'un épaulement 3111. Le manchon de guidage 3' du boîtier 3 présente un diamètre ajusté à celui de la première partie 210" ou 10210" du manchon étagé de précentrage et de centrage 21 ". Ainsi, lors d'un assemblage du dispositif, la première partie 210" ou 10210" du manchon étagé de précentrage et de centrage 21" de la partie filetée de la broche 21' coopère avec le manchon de guidage 3' du boîtier 3.The nut 31 is an interchangeable floating nut having a threaded portion 311, having a face 311 'bearing against a guide sleeve 3' of the housing 3, and a portion for maintaining rotation and translational guide 312 cooperating with the retaining means 33 of said housing 3, the junction between the threaded portion 311 and the rotational and translational guiding portion 312 being in the form of a shoulder 3111. The guide sleeve 3 'of the housing 3 has a diameter adjusted to that of the first portion 210 "or 10210" of the pre-centering and centering step sleeve 21 ". Thus, during assembly of the device, the first part 210" or 10210 "of the stepped pre-centering and centering sleeve 21 "Of the threaded portion of the pin 21 'cooperates with the guide sleeve 3' of the housing 3.

Selon une caractéristique de l'invention, le moyen de retenue 33 dudit boîtier 3, coopérant avec la partie de maintien en rotation et de guidage en translation 312 de l'écrou 31, est sous forme d'une platine munie d'un évidement de section oblongue 3121 logeant ladite partie de maintien en rotation et de guidage en translation 312, avec liberté de déplacement en translation par rapport à l'axe longitudinal de l'écrou 31, ainsi que suivant l'axe de l'évidement de section oblongue 3121.According to one characteristic of the invention, the retaining means 33 of said housing 3, cooperating with the part for keeping in rotation and guiding in translation 312 of the nut 31, is in the form of a plate provided with a recess of oblong section 3121 housing said portion for maintaining rotation and translational guide 312, with freedom of displacement in translation relative to the longitudinal axis of the nut 31, as well as along the axis of the recess of oblong section 3121 .

La partie de maintien en rotation et de guidage en translation 312 de l'écrou 31 se présente préférentiellement sous forme d'une douille prolongeant la partie taraudée 311 et présentant deux méplats parallèles 312', dont l'écartement est légèrement inférieur à la largeur de l'évidement de section oblongue 3121 de la platine formant le moyen de retenue 33 du boîtier 3. Ainsi, l'écrou 31 est maintenu en rotation, tout en présentant une liberté de déplacement verticalement par rapport à l'axe du manchon de guidage 3' du boîtier 3 et en direction de ce manchon 3'.The portion for maintaining rotation and guiding in translation 312 of the nut 31 is preferentially in the form of a sleeve extending the tapped portion 311 and having two parallel flats 312 ', whose spacing is slightly less than the width of the oblong section recess 3121 of the plate forming the retaining means 33 of the casing 3. Thus, the nut 31 is kept in rotation, while presenting a freedom of movement vertically relative to the axis of the guide sleeve 3 'of the housing 3 and towards the sleeve 3'.

Par ailleurs, la platine formant le moyen de retenue 33 est maintenue dans le boîtier 3 de l'écrou 31, d'une part, par mise en butée, par la face extérieure de son bord correspondant, contre un rebord 7 perpendiculaire à la face arrière de la peau coffrante de la banche et, d'autre part, par appui du bord opposé contre un verrou amovible 8 fixé dans le boîtier 3. La distance entre la face de la platine formant le moyen de retenue 33 et le manchon de guidage 3' du boîtier 3 est supérieure à la longueur de la partie taraudée 311, de préférence de quelques millimètres. Ainsi, le degré de liberté de l'écrou 31 en translation par rapport à son axe longitudinal est assuré en toute circonstance, tout en évitant que l'écrou 31 puisse sortir du boîtier 3, en position de non utilisation.Furthermore, the plate forming the retaining means 33 is held in the casing 3 of the nut 31, on the one hand, by abutment, by the outer face of its corresponding edge, against a flange 7 perpendicular to the face rear of the skin forming formwork and, secondly, by pressing the opposite edge against a removable lock 8 fixed in the housing 3. The distance between the face of the plate forming the retaining means 33 and the guide sleeve 3 'of the housing 3 is greater than the length of the threaded portion 311, preferably a few millimeters. Thus, the degree of freedom of the nut 31 in translation relative to its longitudinal axis is ensured in all circumstances, while avoiding that the nut 31 can leave the housing 3 in the non-use position.

Le verrou amovible 8 se présente, de préférence, sous forme d'une barrette pourvue à une extrémité d'une tête élargie et coopérant sur deux côtés horizontaux opposés du boîtier 3, près du bord opposé à celui correspondant au rebord 7 perpendiculaire à la face arrière de la peau coffrante, avec des ouvertures de section correspondante prévues dans lesdits côtés horizontaux, son maintien en position de service étant assuré par l'intermédiaire d'une goupille traversant l'extrémité opposée à la tête élargie et s'appuyant sur la face externe du côté horizontal correspondant.The removable latch 8 is preferably in the form of a bar provided at one end of an enlarged head and cooperating on two opposite horizontal sides of the housing 3, near the edge opposite that corresponding to the flange 7 perpendicular to the face. rear of the skin formwork, with openings of corresponding section provided in said horizontal sides, its holding in the operating position being provided by means of a pin through the end opposite the enlarged head and resting on the face external side of the corresponding horizontal side.

Ainsi, il est possible de monter facilement et rapidement l'écrou 31 dans le boîtier 3 et d'assurer son maintien en position de non utilisation en évitant tout risque de perte de l'écrou.Thus, it is possible to easily and quickly mount the nut 31 in the housing 3 and ensure its maintenance in the non-use position by avoiding any risk of loss of the nut.

En outre, selon une autre caractéristique de l'invention, l'écrou 31 peut être réalisé en un acier noble ou ayant subi un traitement de surface particulier en vue de l'amélioration du coefficient de frottement et/ou des caractéristiques mécaniques, ainsi que de résistance à la corrosion, alors que les autres éléments du boîtier 3 peuvent être réalisés en un acier de moindre coût.In addition, according to another characteristic of the invention, the nut 31 may be made of a noble steel or having undergone a particular surface treatment for the purpose of improving the coefficient of friction and / or the mechanical characteristics, as well as resistance to corrosion, while the other elements of the housing 3 can be made of a lower cost steel.

Conformément à une autre caractéristique de l'invention, le filetage de l'extrémité filetée de la broche 21' constitutive de la vis 21 et le taraudage de la partie taraudée 311 de l'écrou 31 sont avantageusement réalisés sous forme de filetage et taraudage à pas rapides autonettoyants. Ces filetage et taraudage sont sous forme de filets ronds, dont les sommets ont été aplatis par usinage. Ainsi, ces filetage et taraudage coopèrent entre eux uniquement par leur flanc tout en laissant subsister des fonds de filet vides, de sorte que les impuretés dû au coulage du béton peuvent éventuellement se déposer dans ces fonds de filet et être facilement éliminées après démontage, tout en évitant de produire un grippage de l'assemblage vissé. En effet, si des impuretés se déposent sur l'ensemble de la surface des filets, le début de la manoeuvre de dévissage d'une vis aura pour conséquence immédiate de déplacer par gravité ces impuretés vers le fond des filets, dans lequel elles pourront se déposer sans risquer un grippage.According to another characteristic of the invention, the threading of the threaded end of the pin 21 'constituting the screw 21 and the tapping of the threaded portion 311 of the nut 31 are advantageously made in the form of threading and internal threading. not fast self-cleaning. These threads and tapping are in the form of round threads, whose tops have been flattened by machining. Thus, these threads and tapping cooperate with each other only by their side while leaving net funds empty, so that the impurities due to the pouring of the concrete can possibly be deposited in these net funds and be easily removed after disassembly, while avoiding to produce seizure of the screwed connection. Indeed, if impurities are deposited on the entire surface of the nets, the beginning of the unscrewing operation of a screw will have the immediate consequence of moving by gravity these impurities to the bottom of the nets, in which they can deposit without risk of seizure.

Lors d'un assemblage des rives de deux banches voisines, la vis 21 d'un boîtier 2 est mise sensiblement en prolongement de l'écrou 31 d'un boîtier 3 (figures 1 et 2), puis la broche 21' est introduite par son extrémité filetée, après passage à travers la douille de guidage correspondante 22 du boîtier 2 et le manchon du guidage 3' du boîtier 3, dans la partie taraudée 311 de l'écrou 31 du boîtier 3. Lors de cette première opération, qui est effectuée par manoeuvre de la vis 21 au moyen de sa poignée de manoeuvre 21"", la vis 21 réalise un premier alignement avec l'écrou 31 en bénéficiant d'un large degré de liberté dans toutes les directions, la vis 21 n'étant pas encore guidée axialement, si ce n'est très grossièrement dans le manchon 3' du boîtier 3 et dans la douille de guidage 22 du boîtier 2.When assembling the banks of two adjoining banks, the screw 21 of a housing 2 is substantially in extension of the nut 31 of a housing 3 (Figures 1 and 2), then the pin 21 'is introduced by its threaded end, after passing through the corresponding guide sleeve 22 of the housing 2 and the sleeve of the guide 3 'of the housing 3, in the threaded portion 311 of the nut 31 of the housing 3. During this first operation, which is performed by maneuvering the screw 21 by means of its operating handle 21 "", the screw 21 makes a first alignment with the nut 31 enjoying a large degree of freedom in all directions, the screw 21 being not yet axially guided, if not very coarsely in the sleeve 3 'of the housing 3 and in the guide bushing 22 of the housing 2.

Par vissage de la vis 21 dans l'écrou 31, la vis 21 se déplace en direction de l'écrou 31 en étant guidée sur l'axe longitudinal formant le moyen de retenue 23 au moyen de la patte de liaison 5, de sorte que ledit écrou 31 est attiré contre le manchon de guidage 3' du boîtier 3 par sa face d'appui 311', et la première partie 210" ou 10210" du manchon étagé de précentrage et de centrage 21" de la vis 21 pénètre d'abord dans la douille de guidage 22 du boîtier 2, puis dans le manchon de guidage 3' du boîtier 3 de l'écrou 31. Cette dernière pénétration a pour effet de réaliser un alignement axial entre l'écrou 31 et la vis 21. Cependant, il subsiste une certaine liberté de déviation de l'axe de l'ensemble du dispositif d'assemblage, tant que la deuxième partie 211" ou 10211" du manchon étagé de précentrage et de centrage 21" de la vis 21 n'a pas pénétré dans la douille de guidage 22 du boîtier 2.By screwing the screw 21 in the nut 31, the screw 21 moves towards the nut 31 while being guided on the longitudinal axis forming the retaining means 23 by means of the connecting lug 5, so that said nut 31 is drawn against the guide sleeve 3 'of the housing 3 by its bearing face 311', and the first portion 210 "or 10210" of the stepped pre-centering and centering sleeve 21 "of the screw 21 penetrates first in the guide sleeve 22 of the housing 2, then in the guide sleeve 3 'of the housing 3 of the nut 31. The latter penetration has the effect of achieving an axial alignment between the nut 31 and the screw 21. However, there remains a certain freedom of deviation from the axis of the assembly assembly assembly, as long as the second portion 211 "or 10211" of the stepped pre-centering and centering sleeve 21 "of the screw 21 does not penetrated into the guide sleeve 22 of the housing 2.

Lors du vissage final de la vis 21 dans l'écrou 31, par action sur son polygone de manoeuvre 21"', cette deuxième partie 211" ou 10211" pénètre alors dans la douille de guidage 22, dont la section est ajustée à celle de cette deuxième partie, de sorte que l'axe du boîtier 2 comportant la vis 21 est exactement aligné avec celui du boîtier 3 de logement de l'écrou 31 et que le centrage définitif est réalisé. Il s'ensuit que les rives des banches 1, 1' portant les boîtiers 2 et 3 présentent un alignement parfait de la face de leur peau coffrante.When final screwing of the screw 21 in the nut 31, by action on its maneuvering polygon 21 "', this second portion 211" or 10211 "then enters the guide sleeve 22, whose section is adjusted to that of this second part, so that the axis of the housing 2 comprising the screw 21 is exactly aligned with that of the housing 3 housing the nut 31 and that the final centering is achieved. It follows that the banks of the panels 1, 1 'carrying the casings 2 and 3 have a perfect alignment of the face of their skin formante.

Lors du serrage final de la vis 21 dans l'écrou 31, la manoeuvre de la vis est maintenue relativement aisée, dans les deux modes de réalisation, soit du fait de la prévision de la partie filetée 21' de la broche et du manchon étagé de précentrage et de centrage 21" en un matériau traité ou noble favorisant le glissement (figures 1 à 3), soit par le fait que le manchon étagé de précentrage et de centrage 21" est monté libre en rotation sur la broche 21' (figure 4), de sorte que l'emmanchement de ce manchon 21" dans les guides correspondants s'effectue sans nuire à la possibilité de rotation de ladite broche 21'. En outre, du fait du léger jeu longitudinal entre le manchon 21" et la broche 21' prévu dans le mode de réalisation suivant la figure 4, un serrage de rapprochement définitif des rives 1, 1' peut être assuré dans tous les cas.When final tightening of the screw 21 in the nut 31, the operation of the screw is kept relatively easy, in both embodiments, either because of the prediction of the threaded portion 21 'of the spindle and the stepped sleeve 21 "pre-centering and centering in a treated or noble material promoting sliding (Figures 1 to 3), or in that the precentering and centering step sleeve 21" is rotatably mounted on the pin 21 '(FIG. 4), so that the fit of this sleeve 21 "in the corresponding guides is effected without impairing the possibility of rotation of said pin 21 'Furthermore, because of the slight longitudinal clearance between the sleeve 21" and the pin 21 'provided in the embodiment according to Figure 4, a final approximation clamping edges 1, 1' can be assured in all cases.

Pour les ensembles vis et écrou mettant en oeuvre des éléments selon les figures 1 à 3, le démontage initial, correspondant au desserrage de la partie filetée, s'effectue de manière simple et aisée, tout grippage étant évité du fait du traitement de surface de ces éléments.For screw and nut assemblies employing elements according to FIGS. 1 to 3, the initial disassembly, corresponding to the loosening of the threaded part, is carried out in a simple and easy manner, any seizure being avoided because of the surface treatment of these elements.

Lors du démontage d'un dispositif selon la figure 4, la manoeuvre de la vis au moyen du polygone de manoeuvre 21'" a pour effet, dans un premier temps, de déplacer d'abord légèrement la broche 21' dans le manchon étagé de précentrage et de centrage 21". Pendant ce très court mouvement de déplacement de la broche 21', il se produit simultanément un dégrippage des filetages de la vis 21 et de l'écrou 31. Ensuite, du fait de l'ajustement du manchon étagé 21" respectivement dans le manchon de guidage 3' du boîtier 3 et dans la douille de guidage 22 du boîtier 2, qui a pour conséquence une certaine résistance au glissement dudit manchon dans ces parties de guidage, l'écrou 31 est déplacé en direction de la platine formant la partie de maintien en rotation et de guidage en translation 312 de l'écrou 31, de sorte que la face 311' d'appui contre le manchon de guidage 3' du boîtier 3 de sa partie taraudée 311 est décollée dudit manchon de guidage 3' et que ledit écrou 31 s'appuie, à l'extrémité des deux méplats parallèles 312' de la douille prolongeant la partie taraudée 311 contre ladite platine, sous les bords de l'évidement de section oblongue 3121 logeant ladite partie de maintien en rotation et de guidage en translation 312 de l'écrou 31.When disassembling a device according to Figure 4, the operation of the screw by means of the operating polygon 21 '' has the effect, at first, first slightly move the pin 21 'in the stepped sleeve of pre-centering and centering 21 ". During this very short movement of the spindle 21 ', simultaneously the threads of the screw 21 and the nut 31 are released. Then, because of the adjustment of the stepped sleeve 21 "respectively in the sleeve of 3 'guiding of the housing 3 and in the guide sleeve 22 of the housing 2, which results in a certain resistance to sliding of said sleeve in these guide parts, the nut 31 is moved in the direction of the plate forming the holding portion rotating and guiding in translation 312 of the nut 31, so that the face 311 'bearing against the guide sleeve 3' of the housing 3 of its threaded portion 311 is detached from said guide sleeve 3 'and that said nut 31 rests, at the end of the two parallel flats 312 'of the sleeve extending the threaded portion 311 against said plate, under the edges of the oblong section recess 3121 housing said portion for holding in rotation and guiding tra nslation 312 of the nut 31.

Une poursuite du dévissage de la vis 21 a alors pour effet de provoquer le déplacement de la vis en direction opposée à l'écrou 31 et ainsi d'entraîner, du fait de la liaison de la broche 21' avec le manchon étagé 21", ledit manchon étagé 21" et de l'arracher hors de ses guidages respectifs dans le manchon de guidage 3' du boîtier 3 et dans la douille de guidage 22 du boîtier 2.
