Description

  

  Assemblage d'angle pour construction comprenant deux parois perpendiculaires    Certaines constructions légères isothermes sont  réalisées au moyen d'éléments composites appelés  couramment sandwiches. Ces éléments sont consti  tués<B>de</B> trois couches planes collées les unes sur les  autres<B>:</B> une couche centrale, assez épaisse en un  matériau léger, par exemple une résine synthétique  cellulaire, et sur chaque face de cette couche, une  feuille mince, plus dure et plus résistante. Les, deux  faces du sandwich peuvent être identiques ou diffé  rentes. L'épaisseur de la couche intermédiaire est  généralement comprise entre 20 et 200 mm.  



  Un tel élément sera appelé plus simplement par  la suite<B> </B> un sandwich      .     



  Dans une construction comprenant des sandwi  ches, les différents éléments de chaque sandwich tra  vaillent de façons différentes pour participer<B>à</B> la  solidité de la construction. En particulier dans la  couche intermédiaire qui est légère, il est intéressant  que les, efforts soient répartis dans la masse d'une  façon aussi homogène que possible.  



  Les efforts ne pouvant être appliqués qu'aux<B>élé-</B>  ments extérieurs du sandwich, ces éléments répartis  sent les efforts dans la couche intermédiaire qui les  transmet d'une face<B>à</B> l'autre.  



  Dans une construction comprenant un assemblage  de deux sandwiches, l'ensemble peut être soumis<B>à</B>  des efforts<B>de</B> résistance aux déformations et l'on a  trouvé que la couche intermédiaire n'était pas tou  jours suffisante pour assurer la transmission et la  répartition des efforts entre les deux parois extérieu  res des sandwiches quand les deux sandwiches sont  raccordés suivant un angle, en particulier<B>à</B> la liaison  d'une paroi verticale avec une paroi horizontale, par  exemple au raccordement de la paroi verticale avec  le plancher, dans un véhicule routier ou ferroviaire.

      La présente invention a pour objet un assemblage  d'angle pour construction comprenant deux parois  perpendiculaires notamment le plancher et la paroi  verticale d'un véhicule isotherme, les deux parois  étant des sandwiches, c'est-à-dire constituées     d!une     couche en matériau rigide et léger, d'une épaisseur  comprise entre 20 et     200mm,    revêtue sur ses deux  faces de revêtements durs et rigides, les revêtements  internes des parois perpendiculaires étant fixés l'un  <B>à</B> l'autre, et les revêtements.

   externes étant aussi fixés  l'un<B>à</B> l'autre, caractérisé par le fait que les revête  ments internes et externes sont reliés l'un<B>à</B> l'autre  par trois entretoises parallèles<B>à</B> l'arête de l'angle,  une entretoise étant placée le long de     Parête        elle-          même    et deux autres entretoises étant placées cha  cune dans une des parois perpendiculaires,<B>à</B> une  distance<B>de</B> l'arête comprise entre une et quatre fois  l'épaisseur de la couche intermédiaire en matériau  rigide et léger.  



  Une forme d'exécution de l'objet de la présente  invention va maintenant être décrite,<B>à</B> titre     d7exem-          ple,    en regard du dessin ci-joint qui représente en  coupe, la liaison de la paroi verticale     d#un    camion  isotherme avec le plancher. La paroi verticale du  camion est constituée par un sandwich<B>1</B> et la paroi  horizontale par un sandwich 2. Ces sandwiches com  portent des couches internes ou âmes<B>3</B> et 4 en un  matériau léger et isolant     thermiquement,    par exemple  en     polychlorure    de vinyle cellulaire.

   Ces âmes sont  garnies sur leurs deux faces par des feuilles dures  et résistantes<B>5, 6, 7, 8.</B> Ces feuilles, peuvent être de  toute nature appropriée suivant l'usage du camion:  aluminium, contreplaqué, résine synthétique renfor  cée ou non par des fibres. Elles peuvent être toutes  identiques, ou peuvent être différentes selon les qua  lités recherchées pour le plancher, pour les parois  internes, ou les parois externes. Les deux sandwiches      <B>1</B> et 2 peuvent avoir la même épaisseur ou des épais  seurs différentes. L'épaisseur<B>de</B> l'âme peut être ici,  pour les deux sandwiches     d#environ   <B>80</B> mm.  



  Les parois internes entre elles et les parois exter  nes entre elles sont raccordées     angulairement    d'une  manière classique. Les parois<B>5</B> et<B>7</B> sont fixées, cha  cune, par des rivets<B>9</B> et<B>10 à</B> une cornière<B>11.</B> Cette  cornière<B>11</B> assure la liaison entre les deux parois<B>5</B>  et<B>7</B> et renforce la structure. Les parois<B>6</B> et<B>8</B> sont  aussi fixées, chacune par des rivets 12 et<B>13 à</B> une  cornière 14, qui assure la liaison entre les deux parois  <B>6</B> et<B>8</B> et renforce également la structure. La struc  ture     estencore    renforcée par un élément plat<B>15</B> qui  court tout<B>le</B> long de la ligne de jonction et qui est  appliqué contre la paroi<B>8</B> pour la raidir dans sa  partie inférieure.

   Cet élément plat<B>15</B> peut être en  métal, en bois ou en matière synthétique.  



  On place des liaisons rigides ou entretoises entre  les parois<B>5</B> et<B>6</B> d'une part, et<B>7</B> et<B>8</B> d'autre part,<B>à</B>  la jonction elle-même c'est-à-dire suivant l'arête de  l'angle qu'elles forment et<B>à</B> une certaine distance de  la jonction, ces liaisons s'étendant d'une manière con  tinue, parallèlement<B>à</B> la jonction. Ces liaisons peu  vent être constituées par un profilé en matière résis  tante et isolante.     Etant    donné l'utilisation de la cons  truction, ce profilé sera aussi peu conducteur de la  chaleur que possible.<B>Il</B> sera par exemple en une  résine synthétique comme un polyester.  



  Un profilé<B>16</B> relie la paroi interne<B>à</B> la paroi  externe dans les régions où ces parois forment un  angle; il peut être, fixé par exemple<B>à</B> la paroi<B>5</B> et  en même temps<B>à</B> la cornière<B>11</B> par le rivet<B>9</B> et  être rivé sur la paroi<B>6 à</B> l'autre extrémité. Tel que  représenté sur le dessin, un des côtés du profilé<B>16</B>  forme le prolongement de la surface interne de la  paroi<B>7, à</B> laquelle il est relié par l'intermédiaire de  la cornière<B>11.</B>  



  Un profilé<B>17</B> relie<B>le-,</B> deux parois<B>5</B> et<B>6</B> au  moyen de rivets par exemple. Il peut être placé<B>à</B>  environ     300mm.    de l'arête de la cornière 14.    D'une manière analogue, un autre profilé<B>18</B> en  polyester relie les deux parois<B>7</B> et<B>8</B> et est placé<B>à</B>  environ 200 mm. de     Farête    de la cornière 14.  



  Ces trois profilés<B>16, 17</B> et<B>18</B> s'étendent     paral-          lùlement   <B>à</B> la cornière 14.  



  Des essais comparatifs ont montré que la résis  tance d'un assemblage d'angle ainsi renforcé était  supérieure d'une proportion importante et imprévi  sible a priori, par rapport<B>à</B> un assemblage du même  genre ne comportant pas, les profilés de renforcement.



  Corner assembly for construction comprising two perpendicular walls Certain light isothermal constructions are made using composite elements commonly called sandwiches. These elements are made up of <B> </B> three flat layers glued on top of each other <B>: </B> a central layer, quite thick in a light material, for example a cellular synthetic resin, and on each side of this layer, a thin sheet, harder and more resistant. The two sides of the sandwich may be identical or different. The thickness of the intermediate layer is generally between 20 and 200 mm.



  Such an element will hereinafter be called more simply <B> </B> a sandwich.



  In a construction including sandwiches, the different elements of each sandwich work in different ways to contribute <B> to </B> the strength of the construction. In particular in the intermediate layer which is light, it is advantageous that the forces are distributed throughout the mass as homogeneously as possible.



  As the forces can only be applied to the exterior <B> elements </B> of the sandwich, these distributed elements feel the forces in the intermediate layer which transmits them from one face <B> to </B> the other.



  In a construction comprising an assembly of two sandwiches, the assembly can be subjected <B> to </B> forces <B> of </B> resistance to deformation and it has been found that the intermediate layer was not not always sufficient to ensure the transmission and distribution of the forces between the two exterior walls of the sandwiches when the two sandwiches are connected at an angle, in particular <B> to </B> the connection of a vertical wall with a horizontal wall, for example at the connection of the vertical wall with the floor, in a road or rail vehicle.

      The present invention relates to a corner assembly for construction comprising two perpendicular walls, in particular the floor and the vertical wall of an isothermal vehicle, the two walls being sandwiches, that is to say made up of a layer in rigid and light material, with a thickness of between 20 and 200mm, coated on both sides with hard and rigid coatings, the internal coatings of the perpendicular walls being fixed one <B> to </B> the other, and coatings.

   external being also fixed one <B> to </B> the other, characterized in that the internal and external coverings are connected one <B> to </B> the other by three parallel spacers <B> at </B> the edge of the angle, a spacer being placed along the edge itself and two other braces being placed each in one of the perpendicular walls, <B> at </B> a distance <B> from </B> the edge between one and four times the thickness of the intermediate layer in rigid and light material.



  An embodiment of the object of the present invention will now be described, <B> by </B> by way of example, with reference to the attached drawing which represents in section, the connection of the vertical wall of the invention. #an insulated truck with the floor. The vertical wall of the truck is made up of a sandwich <B> 1 </B> and the horizontal wall of a sandwich 2. These sandwiches have internal layers or cores <B> 3 </B> and 4 in a light material. and thermally insulating, for example cellular polyvinyl chloride.

   These cores are lined on both sides with hard and resistant sheets <B> 5, 6, 7, 8. </B> These sheets can be of any suitable nature depending on the use of the truck: aluminum, plywood, resin synthetic reinforced or not by fibers. They can all be identical, or can be different depending on the desired qualities for the floor, for the internal walls, or the external walls. The two sandwiches <B> 1 </B> and 2 can have the same thickness or different thicknesses. The <B> core </B> thickness can be here, for both sandwiches around <B> 80 </B> mm.



  The internal walls between them and the external walls between them are angularly connected in a conventional manner. The walls <B> 5 </B> and <B> 7 </B> are each fixed by rivets <B> 9 </B> and <B> 10 to </B> an angle <B > 11. </B> This angle <B> 11 </B> ensures the connection between the two walls <B> 5 </B> and <B> 7 </B> and reinforces the structure. The walls <B> 6 </B> and <B> 8 </B> are also fixed, each by rivets 12 and <B> 13 to </B> an angle 14, which provides the connection between the two walls <B> 6 </B> and <B> 8 </B> and also strengthens the structure. The structure is further reinforced by a flat element <B> 15 </B> which runs all <B> the </B> along the junction line and which is applied against the wall <B> 8 </B> for stiffen it in its lower part.

   This flat <B> 15 </B> element can be made of metal, wood or synthetic material.



  Rigid connections or spacers are placed between the walls <B> 5 </B> and <B> 6 </B> on the one hand, and <B> 7 </B> and <B> 8 </B> on the other hand, <B> at </B> the junction itself, that is to say according to the edge of the angle that they form and <B> at </B> a certain distance of the junction, these links extending in a continuous fashion, parallel <B> to </B> the junction. These connections may be formed by a section of resistant and insulating material. Given the use of the construction, this profile will be as little heat conductor as possible. <B> It </B> will for example be made of a synthetic resin such as a polyester.



  A profile <B> 16 </B> connects the internal wall <B> to </B> the external wall in the regions where these walls form an angle; it can be, for example, fixed <B> to </B> the wall <B> 5 </B> and at the same time <B> to </B> the angle bar <B> 11 </B> by the rivet <B> 9 </B> and be riveted to the wall <B> 6 at </B> the other end. As shown in the drawing, one of the sides of the profile <B> 16 </B> forms the extension of the internal surface of the wall <B> 7, to which it is connected by means of the angle <B> 11. </B>



  A profile <B> 17 </B> connects <B> le-, </B> two walls <B> 5 </B> and <B> 6 </B> by means of rivets for example. It can be placed <B> at </B> around 300mm. of the edge of the angle 14. In a similar manner, another section <B> 18 </B> in polyester connects the two walls <B> 7 </B> and <B> 8 </B> and is placed <B> at </B> approximately 200 mm. of the edge of the angle 14.



  These three profiles <B> 16, 17 </B> and <B> 18 </B> extend parallel <B> to </B> the angle 14.



  Comparative tests have shown that the strength of a corner assembly thus reinforced was greater by a significant proportion and a priori unpredictable, compared to <B> </B> an assembly of the same type not comprising, the reinforcement profiles.
