The spindle is handled during dismounting of formwork after unlocking the spindle to bring a ground support plate (53) in contact with an inner face of the shaft.

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 de banches de coffrage de murs et de voiles, et a pour objet une banche pour le coffrage de murs ou de voiles munie d'un vérin de réglage de niveau.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 including wall formwork and walls, and has for object a formwork for the formwork of walls or sails equipped with a level adjustment cylinder.

Actuellement le coffrage de murs et de planchers est généralement effectué au moyen, respectivement, de banches et de tables de coffrage.Currently the formwork of walls and floors is usually carried out by means of, respectively, banches and formwork tables.

Ainsi, il existe divers types de banches permettant la réalisation de murs et qui sont généralement 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.Thus, there are various types of panels for the realization of walls and which are generally constituted by a formwork surface itself, by ground support means and verticality adjustment and by means of assembling adjacent banches between them.

Les moyens d'appui au sol et de réglage de la verticalité se présentent sous forme de vérins montés sur les raidisseurs de ces derniers. De tels vérins sont notamment connus par NL-A-8 105 300 et par IT-A-1 033 914 .The ground support and vertical adjustment means are in the form of jacks mounted on the stiffeners of the latter. Such cylinders are in particular known by NL-A-8 105 300 and by IT-A-1,033,914 .

Ces vérins connus, qui s'appuient sur le sol par l'intermédiaire d'une petite platine rapportée à ladite extrémité, permettent, certes, d'assurer correctement leur fonction de réglage de niveau des banches, mais sont peu ergonomique et donc difficiles, voire pénibles à manoeuvrer. En outre, du fait de leur positionnement dans la rive horizontale inférieure, la surface d'appui formée par leur platine d'appui est relativement faible, de sorte que la pression au sol de ces platines est très forte.These known cylinders, which rely on the ground via a small plate attached to said end, allow, certainly, to ensure their proper level adjustment function of the banks, but are poor ergonomic and therefore difficult, even difficult to maneuver. In addition, because of their positioning in the lower horizontal edge, the bearing surface formed by their support plate is relatively small, so that the ground pressure of these plates is very strong.

Enfin, le montage de ces vérins entre les raidisseurs nécessite qu'ils soient relativement courts, de sorte qu'ils ne présentent qu'une faible possibilité de rattrapage de dénivellation.Finally, the mounting of these cylinders between the stiffeners requires that they be relatively short, so that they have only a small possibility of catching up the slope.

La présente invention a pour but de pallier ces inconvénients en proposant une banche pour le coffrage de murs ou de voiles munie d'un vérin de réglage de niveau permettant un meilleur appui au sol et présentant une ergonomie améliorée.The present invention aims to overcome these disadvantages by providing a formwork for the formwork of walls or sails provided with a level adjustment cylinder for better ground support and having improved ergonomics.

A cet effet, la banche pour le coffrage de murs ou de voiles, qui est essentiellement pourvue d'une face coffrante et de raidisseurs horizontaux et munie d'un vérin de réglage de niveau monté hors de l'encombrement des raidisseurs horizontaux de la banche, caractérisée en ce que le vérin de réglage de niveau est monté dans le bord de la rive horizontale inférieure et s'étend sur une hauteur importante, à savoir correspondant à plusieurs niveaux de raidisseurs horizontaux, de sorte que sa manoeuvre puisse être effectuée à hauteur d'homme et en ce que ledit vérin de réglage de niveau est constitué par un fût tubulaire de fixation sur les raidisseurs horizontaux de la banche, par un élément télescopique tubulaire, monté libre en translation et fixe en rotation dans le fût tubulaire et pourvu d'une platine d'appui au sol et par une broche filetée, guidée en rotation et fixée en translation sur l'extrémité supérieure du fût tubulaire et coopérant avec un écrou solidaire de l'extrémité supérieure de l'élément télescopique tubulaire.For this purpose, the formwork for the formwork of walls or sails, which is essentially provided with a formwork face and horizontal stiffeners and provided with a leveling jack mounted out of the space of the horizontal stiffeners of the formwork , characterized in that the leveling ram is mounted in the edge of the lower horizontal edge and extends over a large height, namely corresponding to several levels of horizontal stiffeners, so that its maneuver can be performed at height. of man and in that said leveling jack is constituted by a tubular fixing shaft on the horizontal stiffeners of the box, by a tubular telescopic element, mounted free in translation and fixed in rotation in the tubular shaft and provided with a support plate on the ground and a threaded spindle, guided in rotation and fixed in translation on the upper end of the tubular shaft and cooperating with a frame or integral with the upper end of the tubular telescopic element.

L'invention sera mieux comprise, grâce à la description ci-après, qui se rapporte à un mode de réalisation préféré, donné à titre d'exemple non limitatif, et expliqué avec référence aux dessins schématiques annexé, dans lesquels :

  • la figure 1 est une vue partielle en élévation par l'arrière d'une banche équipée d'un vérin conforme à l'invention ;
  • la figure 2 est une vue en élévation latérale et en coupe de la banche suivant la figure 1, et
  • la figure 3 est une vue partielle arrachée, en perspective, des détails A et B du vérin.
The invention will be better understood, thanks to the following description, which relates to a preferred embodiment, given by way of non-limiting example, and explained with reference to the attached schematic drawings, in which:
  • the figure 1 is a partial view in elevation from the rear of a formwork equipped with a jack according to the invention;
  • the figure 2 is a side elevation and sectional view of the section following the figure 1 , and
  • the figure 3 is a partial view broken away, in perspective, details A and B of the cylinder.

Les figures 1 et 2 des dessins annexés représentent une banche 1 pour le coffrage de murs ou de voiles, qui est essentiellement pourvue d'une face coffrante 2 et de raidisseurs 3, ainsi que de moyens 4 d'assemblage des rives verticales et de vérins de réglage de niveau 5. Du fait que la banche 1 n'est représentée que partiellement, seul un vérin de réglage de niveau 5 est représenté.The figures 1 and 2 the accompanying drawings show a form 1 for the formwork of walls or veils, which is essentially provided with a formwork face 2 and stiffeners 3, and means 4 for assembling vertical edges and leveling actuators 5 Because the blank 1 is only partially shown, only a level 5 adjusting jack is shown.

Conformément à l'invention, le vérin de réglage de niveau 5 est monté hors de l'encombrement des raidisseurs horizontaux 3 de la banche 1, dans le bord de la rive horizontale inférieure 6 et s'étend sur une hauteur correspondant à plusieurs niveaux de raidisseurs horizontaux 3, de sorte que sa manoeuvre puisse être effectuée à hauteur d'homme. Comme le montre plus particulièrement la figure 3 des dessins annexés, le vérin de réglage de niveau 5 est avantageusement constitué par un fût tubulaire 51 de fixation sur les raidisseurs horizontaux 3 de la banche 1, par un élément télescopique tubulaire 52, monté libre en translation et fixe en rotation dans le fût tubulaire 51 et pourvu d'une platine d'appui au sol 53 et par une broche filetée 54, guidée en rotation et fixée en translation sur l'extrémité supérieure du fût tubulaire 51 et coopérant avec un écrou 55 solidaire de l'extrémité supérieure de l'élément télescopique tubulaire 52.In accordance with the invention, the leveling adjustment jack 5 is mounted outside the space occupied by the horizontal stiffeners 3 of the panel 1, in the edge of the lower horizontal strip 6 and extends over a height corresponding to several levels of horizontal stiffeners 3, so that its maneuver can be performed at man's height. As shown more particularly in figure 3 In the accompanying drawings, the level adjustment cylinder 5 is advantageously constituted by a tubular shaft 51 for fixing on the horizontal stiffeners 3 of the panel 1, by a tubular telescopic element 52, mounted free in translation and fixed in rotation in the tubular shaft. 51 and provided with a support plate on the ground 53 and by a threaded spindle 54, guided in rotation and fixed in translation on the upper end of the tubular shaft 51 and cooperating with a nut 55 secured to the upper end of the tubular telescopic element 52.

L'élément télescopique tubulaire 52 présente avantageusement une section extérieure correspondant, avec un léger jeu, à la section intérieure du fût tubulaire 51, ou est pourvu de moyens longitudinaux assurant son positionnement sans possibilité de rotation dans ledit fût tubulaire 51, l'écrou 55 étant préférentiellement de section identique à celle de l'élément télescopique tubulaire 52. De préférence, le fût tubulaire 51 est de section carrée. Une telle section carrée favorise une fixation efficace sur les raidisseurs horizontaux 3 de la banche 1 et est adaptée à une coopération naturelle de guidage avec un élément télescopique tubulaire 52 également de section carrée, sans mise en oeuvre de moyen annexe de guidage en translation et/ou de maintien en rotation.The tubular telescopic element 52 advantageously has an outer section corresponding, with a slight clearance, to the inner section of the tubular shaft 51, or is provided with longitudinal means ensuring its positioning without possibility of rotation in said tubular shaft 51, the nut 55 preferably being of identical section to that of the tubular telescopic element 52. Preferably, the tubular shaft 51 is of square section. Such a square section promotes effective fixing on the horizontal stiffeners 3 of the panel 1 and is adapted to a natural guide cooperation with a tubular telescopic element 52 also of square section, without implementation of ancillary means for guiding in translation and / or keeping in rotation.

Des moyens longitudinaux de positionnement peuvent être, par exemple, des nervures longitudinales diamétralement opposées disposées sur un élément télescopique tubulaire 52 de section circulaire et coopérant avec les coins du fût tubulaire carré 51.Longitudinal positioning means may be, for example, diametrically opposed longitudinal ribs disposed on a tubular telescopic element 52 of circular section and cooperating with the corners of the square tubular shaft 51.

La disposition du vérin 5, telle que décrite ci-dessus, permet d'obtenir un décalage de ce dernier par rapport à l'arrière de la face coffrante 2 de la banche 1 et ainsi de rapprocher son axe vertical de celui passant par le plan du centre de gravité de l'ensemble.The arrangement of the jack 5, as described above, makes it possible to obtain an offset of the latter with respect to the rear of the formwork face 2 of the block 1 and thus to bring its vertical axis closer to the one passing through the plane. the center of gravity of the whole.

La broche filetée 54 est guidée en rotation et fixée en translation sur l'extrémité supérieure du fût tubulaire 51 par l'intermédiaire d'un palier 56, fixé par soudage sur ladite extrémité supérieure et maintenant la broche filetée 54 en translation par coopération, d'une part, avec un épaulement 54' de cette dernière, s'appliquant sur sa face externe et, d'autre part, avec une bague rapportée 54" s'appliquant contre sa face interne.The threaded spindle 54 is guided in rotation and fixed in translation on the upper end of the tubular shaft 51 by means of a bearing 56, fixed by welding on said upper end and holding the threaded spindle 54 in translation by cooperation, on the one hand, with a shoulder 54 'of the latter, applying on its outer face and, on the other hand, with an insert ring 54 "pressing against its inner face.

L'écrou 55 est solidarisé avec l'extrémité supérieure de l'élément télescopique tubulaire 52 par soudage sur ladite extrémité supérieure. Il en résulte que lors d'un actionnement de la broche filetée 54, qui est fixée en translation dans le fût tubulaire 51, l'écrou 55 est forcément déplacé à l'intérieur dudit fût tubulaire 51 et entraîne dans son déplacement l'élément télescopique tubulaire 51.The nut 55 is secured to the upper end of the tubular telescopic member 52 by welding on said upper end. It follows that during an actuation of the threaded spindle 54, which is fixed in translation in the tubular shaft 51, the nut 55 is necessarily moved inside said tubular shaft 51 and causes in its displacement the telescopic element. tubular 51.

Ainsi, par actionnement de la broche filetée 54, il est possible de déplacer l'élément télescopique tubulaire 52 dans le sens d'une sortie en partie inférieure du fût tubulaire 51, pour déplacer la platine d'appui au sol 53 en vue d'un réglage de niveau de la banche 1, ou dans le sens d'une rentrée dans l'élément télescopique tubulaire 52 jusqu'à affleurement de la platine 51 avec le bord inférieur de la banche 1.Thus, by actuation of the threaded spindle 54, it is possible to move the tubular telescopic element 52 in the direction of an exit lower part of the tubular shaft 51, to move the support plate to the ground 53 for a level adjustment of the block 1, or in the direction of a re-entry into the tubular telescopic element 52 to outcrop of the plate 51 with the lower edge of the board 1.

Selon une caractéristique de l'invention, l'extrémité supérieure de la broche filetée 54 est pourvue, au-dessus de l'épaulement 54', d'un polygone de manoeuvre 54"' et, en prolongement de ce dernier, d'une poignée moletée 54"". Cette poignée moletée 54"" permet de réaliser la manoeuvre préalable destinée à amener la platine d'appui au sol 53 en contact avec ce dernier, de sorte que seul le réglage final de niveau de la banche 1 sera à effectuer au moyen du polygone de manoeuvre 54"'. Il en est de même en ce qui concerne la manoeuvre de la broche filetée 54 lors du démontage d'un coffrage après desserrage de ladite broche, pour ramener la platine d'appui au sol 53 en contact avec la face inférieure du fût tubulaire carré 51. Il en résulte que les manoeuvres préalables au réglage de niveau, ainsi que de rétraction de l'élément télescopique tubulaire 52 peuvent être effectuées simplement et rapidement de manière manuelle par un opérateur, donc sans mise en oeuvre fastidieuse d'une clé, cette dernière servant uniquement à la manoeuvre finale de réglage de niveau et au desserrage préalable lors d'un décoffrage.According to one characteristic of the invention, the upper end of the threaded spindle 54 is provided, above the shoulder 54 ', with a maneuvering polygon 54 "' and, in extension thereof, with a This knurled handle 54 "" makes it possible to carry out the preliminary operation intended to bring the support plate to the ground 53 in contact with the latter, so that only the final level adjustment of the blank 1 will be perform by means of the maneuvering polygon 54 "'. It is the same with regard to the operation of the threaded spindle 54 during disassembly of a form after loosening said spindle, to return the support plate to the ground 53 in contact with the underside of the square tubular shaft 51 As a result, the pre-leveling and retraction maneuvers of the tubular telescopic element 52 can be carried out simply and quickly manually by an operator, thus without the tedious implementation of a key, the latter used only for the final leveling maneuver and the preliminary loosening during stripping.

Du fait du montage du vérin 5 en dehors de l'encombrement des raidisseurs horizontaux 3, l'espace disponible derrière la face coffrante de la banche, sous la rive horizontale inférieure 6 est plus important et la platine d'appui au sol 53 peut présenter une plus grande surface d'appui au sol que les platines connues à ce jour.Due to the mounting of the cylinder 5 outside the space requirement of the horizontal stiffeners 3, the space available behind the formwork side of the panel, below the lower horizontal edge 6 is larger and the ground support plate 53 can present a larger ground support surface than the known plates to date.

En outre, du fait que le vérin 5 s'étend sur une hauteur importante, à savoir correspondant à plusieurs raidisseurs horizontaux 3, sa manoeuvre peut être effectuée à hauteur d'homme et est donc nettement moins pénible que celle des vérins actuels, dont l'organe de manoeuvre s'étend entre la rive inférieure 6 et le premier raidisseur horizontal. La longueur importante du vérin 5 permet, par ailleurs, d'effectuer d'importants rattrapages de dénivellation sans mise en oeuvre de moyens annexes, tels que des cales ou analogues.In addition, because the jack 5 extends over a large height, namely corresponding to several horizontal stiffeners 3, its maneuver can be performed at human height and is therefore much less painful than that of the current cylinders, which maneuvering member extends between the lower edge 6 and the first horizontal stiffener. The large length of the jack 5 also makes it possible to make significant leveling off of unevenness without the use of auxiliary means, such as wedges or the like.

Grâce à l'invention, il est possible de réaliser un vérin de réglage de niveau pour banche d'utilisation simple et rapide et parfaitement ergonomique.Thanks to the invention, it is possible to achieve a level adjustment jack for easy to use and fast and ergonomically perfect handle.

Bien entendu, l'invention n'est pas limitée au mode de réalisation décrit et représenté aux dessins annexés. Des modifications restent possibles, notamment du point de vue de la constitution des divers éléments ou par substitution d'équivalents techniques, sans sortir pour autant du domaine de protection de l'invention.Of course, the invention is not limited to the embodiment described and shown in the accompanying drawings. Modifications are possible, particularly from the point of view of the constitution of the various elements or by substitution of technical equivalents, without departing from the scope of protection of the invention.
