Description

       

   <Desc/Clms Page number 1> 
 



   L'invention est relative à des perfectionnements apportés aux étais constitués par deux ou plusieurs tubes coulissant l'un dans l'autre qui sont maintenus dans une position déterminée par un dispositif de blo- cage, lesdits étais étant employés notamment pour assurer le support des coffrages, principalement dans la confection des planchers en béton armé ou non, par engagement sous des poutres ou traverses en bois. 



   Selon l'invention, on monte sur la plaque d'assise supérieure de l'étai une console, de longueur importante de préférence, pouvant éven- tuellement être munie de rallonges, fixée sur ladite plaque par simple emboîtement en oblique de celle-ci dans un ajourage de forme appropriée de la console et redressement du montant de l'étai   à   la verticale, des portées conjuguées et des saillies en forme de crochet faisant corps avec la console assurant le verrouillage de la solidarisation de cette dernière avec la tête de   l'étai.   



   L'invention sera mieux comprise en regard du dessin annexé dont la figure unique montre en perspective un mode de réalisation d'une console,   à   placer par exemple comme soutien direct du coffrage d'un plancher l'étai étant montré assemblé avec elle, en traits mixtes. 



   Ainsi que représenté, une console % de forme allongée, est conformée de façon à présenter une surface plane d'appui rectangulaire 1 pourvue à ses deux extrémités d'un retour d'équerre 2, 2a, montée sur deux parties extrêmes triangulaires 3, 3a et une partie médiane rectangulaire 4. 



   Cette partie médiane comporte un ajourage rectangulaire 1 de longueur légèrement supérieure à la longueur de la plaque   d'assise 2   supérieure de l'étai E. et un second   ajourage   parallèle au premier et de même longueur; la hauteur de ce dernier correspond à l'épaisseur de la plaque avec un certain jeu, et celle du premier est supérieure à cette épaisseur. 



  Les deux traverses délimitant les ajourages présentent dans l'axe de la console deux demi-cercles 7,8 en saillies opposées. Enfin, la console est pourvue en saillie dansle plan de sa face d'appui d'une pièce en forme de crochet 9. 



   La partie supérieure de   1'étai [   est présentée obliquement de façon à introduire sa plaque   d'assise ±   en biais dans   l'ajourage   formant une fenêtre de hauteur appropriée pour permettre cette introduction. En redressant alors le montant de l'étai E à la verticale et en l'avançant jusqu'à ce que sa plaque vienne se loger contre sa traverse supérieure 1 de la console, on assure l'emboîtement de cette pièce P, qui est maintenue par le crochet 9, tandis que le montant tubulaire de l'étai se trouve appliqué dans les deux saillies conjuguées opposées 7 et 8. 



   Pour empêcher le crochet 9 de la console ± de se dégager de la plaque d'assise P, ce qui pourrait donner facilement lieu à des accidents par la chute subite de la console, il est indiqué de prévoir sur cette dernière une éclisse 10 qui, lorsque la console occupe sa place sur la plaque d'assise de l'étai de la manière représentée au dessin, sera pivotée vers le haut, c'est-à-dire pressée contre la face inférieure de la plaque   d'as-     sise L   de sorte que celle-ci est maintenue invariablement fixe entre l'éclisse 10 et la traverse supérieure 1. 



   Pour enlever la console de l'étai, l'éclisse 10 est rabattue dans sa position de départ. 



   Le mode d'assemblage, ci-dessus décrit, de la console avec l'étai est particulièrement facile à réaliser et il n'exige aucun organe de. fixation séparé, que l'on risque de perdre. 



   L'étai pourvu de sa console peut être utilisé pour de nombreuses applications, d'autant que la console peut être munie de rallonges. Il est particulièrement indiqué pour remplacer les éléments de soutien des planches en bois ou métalliques d'un coffrage, ce qui est un avantage économique certain.

   Bien entendu, l'on pourra modifier la forme de la console en conservant les ajourages ou pièces en saillie prévues pour le montage de la console sur l'élément supérieur de l'étai. 



    REVENDICATIONS.   



   1 - Perfectionnement aux étais à tubes coulissants maintenus dans une position relative déterminée l'un par rapport à l'autre par un dispositif de blocage, caractérisé en ce que sur la plaque d'assise supérieure de l'étai est montée une console, de longueur importante de préférence, pouvant éventuellement être munie de rallonges, fixée sur ladite plaque par simple emboîtement en oblique de celle-ci dans un ajourage de fôrme appropriée de la console et redressement du montant de   l'étai   à la verticale, des portées conjuguées et des saillies en forme de crochet faisant corps avec la console assurant le verrouillage de la solidarisation de cette dernière avec la tête de l'étai.



   <Desc / Clms Page number 1>
 



   The invention relates to improvements made to the props constituted by two or more tubes sliding one inside the other which are maintained in a position determined by a locking device, said props being used in particular to provide support for the supports. formwork, mainly in the manufacture of reinforced concrete floors or not, by engagement under beams or wooden sleepers.



   According to the invention, a bracket is mounted on the upper base plate of the forestay, preferably of considerable length, which can optionally be provided with extensions, fixed to said plate by simply fitting it obliquely into the latter. an appropriately shaped cutout of the console and straightening of the strut upright vertically, conjugate spans and hook-shaped projections integral with the console ensuring the locking of the attachment of the latter with the head of the prop.



   The invention will be better understood with reference to the appended drawing, the single figure of which shows in perspective an embodiment of a bracket, to be placed for example as direct support for the formwork of a floor, the prop being shown assembled with it, in mixed lines.



   As shown, a console% of elongated shape, is shaped so as to present a flat rectangular support surface 1 provided at its two ends with a right-angle return 2, 2a, mounted on two triangular end parts 3, 3a and a rectangular middle part 4.



   This middle part has a rectangular cutout 1 of length slightly greater than the length of the upper base plate 2 of the strut E. and a second cutout parallel to the first and of the same length; the height of the latter corresponds to the thickness of the plate with a certain clearance, and that of the former is greater than this thickness.



  The two crossbars delimiting the openings have in the axis of the console two semi-circles 7.8 in opposite projections. Finally, the console is provided projecting in the plane of its bearing face with a hook-shaped part 9.



   The upper part of the prop [is presented obliquely so as to introduce its seat plate ± at an angle in the cutout forming a window of suitable height to allow this introduction. By then straightening the upright of the stay E vertically and by advancing it until its plate comes to rest against its upper cross member 1 of the console, it ensures the interlocking of this part P, which is maintained by the hook 9, while the tubular upright of the forestay is applied in the two opposing mating projections 7 and 8.



   To prevent the hook 9 of the console ± from coming free from the base plate P, which could easily give rise to accidents by the sudden drop of the console, it is advisable to provide on the latter a splint 10 which, when the console occupies its place on the seat plate of the forestay as shown in the drawing, will be pivoted upwards, i.e. pressed against the underside of the seat plate L so that the latter is invariably kept fixed between the fishplate 10 and the upper cross member 1.



   To remove the console from the forestay, the splint 10 is folded back to its starting position.



   The method of assembly, described above, of the console with the stay is particularly easy to achieve and it does not require any device. separate fixing, which one risks losing.



   The prop fitted with its console can be used for many applications, especially as the console can be fitted with extensions. It is particularly suitable for replacing the supporting elements of the wooden or metal boards of a formwork, which is a definite economic advantage.

 <Desc / Clms Page number 2>

 



   Of course, the shape of the console can be modified while retaining the cutouts or projecting parts provided for mounting the console on the upper element of the forestay.



    CLAIMS.
