Description

       

  La présente invention a trait à un dispositif de jonction de sections de colonne, comprenant deux éléments terminaux agencés pour couplage mutuel. L'invention est principalement caractérisée en ce qu'au moins deuxorganes de couplage sont présents entre lesdits éléments terminaux, un desdits organes de couplage consistant en une tête de serrage ayant une extension radiale plus petite que celle des éléments terminaux et comportant des surfaces de prise et l'autre desdits organes de couplage consistant en un manchon de serrage entourant ladite tête de serrage de manière périphérique et ayant des surfaces de prise correspondantes, de manière qu'une rotation relative de ces organes, sur une partie d'un tour, autour de l'axe de la colonne, couple entre eux les éléments terminaux et forme un joint rigide.

  
Ce dispositif facilite grandement la jonction des sections de colonne. Lesdites surfaces de prise de la tête de serrage et/ou manchon de serrage forment un angle convenable avec un plan radial des éléments terminaux ou de la colonne. Dans ce dispositif, le bord interne du manchon de serrage, faisant face à la tête de serrage, a sensiblement la même forme que le bord externe de la tête, par suite de quoi, le dispositif est simplifié et sa fabrication est moins coûteuse. Dans une réalisation convenable de l'invention, la tête de serrage est reliée fixement à un élément terminal et le manchon de serrage est relié fixement à l'autre élément terminal de manière qu'en faisant tourner un des éléments terminaux sur une petite partie d'un tour autour de l'axe de la colonne, les éléments terminaux soient reliés et serrés entre eux.

  
Le dispositif de jonction selon l'invention peut être modifié dans les détails de bien des manières. Quelques réalisations de l'invention vont être décrites en se référant aux dessins annexés.

  The present invention relates to a device for joining column sections, comprising two terminal elements arranged for mutual coupling. The invention is mainly characterized in that at least two coupling members are present between said end elements, one of said coupling members consisting of a clamping head having a radial extension smaller than that of the end elements and having engagement surfaces and the other of said coupling members consisting of a clamping sleeve surrounding said clamping head peripherally and having corresponding engaging surfaces, so that relative rotation of these members, over part of a turn, around of the column axis, couples the terminal elements together and forms a rigid joint.

  
This device greatly facilitates the junction of the column sections. Said gripping surfaces of the clamping head and / or clamping sleeve form a suitable angle with a radial plane of the end elements or of the column. In this device, the inner edge of the clamping sleeve, facing the clamping head, has substantially the same shape as the outer edge of the head, as a result, the device is simplified and its manufacture is less expensive. In a suitable embodiment of the invention, the clamping head is fixedly connected to one end element and the clamping sleeve is fixedly connected to the other end element so that by rotating one of the end elements on a small part of the 'one turn around the axis of the column, the terminal elements are connected and clamped together.

  
The junction device according to the invention can be modified in detail in many ways. Some embodiments of the invention will be described with reference to the accompanying drawings.

Figure 3 is a side elevation of the terminal member having the fixed clamp head. Figure 4 is an end view of the latter clamping element.

 <EMI ID = 8.1>

  
whereby, the clamping sleeve and the clamping head can be cut from the same workpiece in a single operation, without loss of material; after the corners of the part 9 have received the draft, they are then fixedly united to their respective end elements. The slanted engagement surfaces 10 of the clamping head forming a suitable angle with a radial plane may instead be provided on the flange 6 or on this flange and on the clamping head.
