Description

       

   <EMI ID=1.1>  l'assemblage en coin de profilés métalliques, plus généralement.. en alliage léger, spécialement dans le domaine de la menuiserie 

  
 <EMI ID=2.1> 

  
Le but essentiel de l'invention est de réaliser de  tels assemblages en coin à l'invervention d'un minimum de  pièces constitutives avec un maximum d'efficacité dans le 

  
 <EMI ID=3.1> 

  
tématiquement entre eux toute solution de continuité. 

  
Une autre caractéristique de-la présente invention  se trouve également dans le fait que, non seulement un tel -  serrage correct est assuré pendant la confection de l'assembla-.  ge en coin, nais également qu'en raison des conditions dans  lesquelles cet assemblage est réalisé, la sollicitation perma-  nente de3 profilés adjacents est maintenue en raison d'une  .résistance systématique opposée à toute tentative de séparation  ou de glissement entre les profilés constitutifs d'un coin.

de jonction*

  
Lesdits perfectionnements peuvent être complétés  par un très léger décalage entre, respectivement, les trous  prévus dans les profilés et les trous correspondants prévus 

  
dans l'équerre de jonction, d'une telle manière que l'axe'des  premiers accuse un léger retard tandis que l'axe des seconds accuse, ipso facto, une légère avance telle que, par l'opération de rivetage, on crée une tension de blocage complémentaire entre les différents éléments adjacents.

  
 <EMI ID=8.1> 

  
blages en coin selon l'invention se trouve dans le fait que les rivets seront, de préférence, mis en oeuvre dans un ordre tel que soient tout d'abord mis en oeuvre les deux rivets les plus éloignés dudit sommet. On favorise ainsi successivement le serrage énergique, respectivement dans le sommet intérieur

  
et dans le sommet extérieur, des ailes ou parois des deux profilés à assembler. 

  
On pourra évidemment adapter ces perfectionnements

  
à tout genre d'applications au prorata de la forme et des dimensions des éléments constitutifs des assemblages à réaliser.. 

  
A simple titre d'exemple, sans caractère limitatif, des réalisations sont décrites ci-après en se référant aux  dessins annexés dans lesquels:  la figure 1 représente aussi sommairement que possi-ble un assemblage en coin appliquant les perfectionnements  selon l'invention; la figure 2 représente, à échelle agrandie, la par- <EMI ID=9.1>  la figure 3'représente à échelle agrandie la partie <EMI ID=10.1>

 <EMI ID = 2.1>

  
The essential aim of the invention is to produce such wedge assemblies with the invervention of a minimum of constituent parts with maximum efficiency in the

Another feature of the present invention is also found in the fact that not only such correct tightening is ensured during the making of the assembly. corner, but also that due to the conditions in which this assembly is carried out, the permanent stress of 3 adjacent profiles is maintained due to a systematic resistance opposed to any attempt at separation or sliding between the constituent profiles from a corner.

Said improvements may be completed by a very slight offset between, respectively, the holes provided in the profiles and the corresponding holes provided.

  
in the junction square, in such a way that the axis of the first shows a slight delay while the axis of the second shows, ipso facto, a slight advance such that, by the riveting operation, we create a complementary blocking voltage between the different adjacent elements.

  
 <EMI ID = 8.1>

  
Wedge according to the invention lies in the fact that the rivets will preferably be implemented in an order such that the two rivets furthest from said crown are first implemented. This successively promotes energetic tightening, respectively in the inner top

  
and in the outer top, the wings or walls of the two sections to be assembled.

  
We can obviously adapt these improvements

  
to all kinds of applications in proportion to the shape and dimensions of the constituent elements of the assemblies to be made.

  
By way of example, without limitation, embodiments are described below with reference to the accompanying drawings in which: Figure 1 shows as summarily as possible a corner assembly applying the improvements according to the invention; FIG. 2 represents, on an enlarged scale, the par- <EMI ID = 9.1> FIG. 3 represents on an enlarged scale the part <EMI ID = 10.1>
