Abstract
Description
La présente invention est relative à un procédé pour renforcer les silos métalliques. The present invention relates to a method for reinforcing metal silos.
On sait qu'un silo métallique est constitué, dans sa forme la plus simple, par quatre panneaux assemblés, deux à deux, par soudage sur des poteaux d'angle ou entre eux. We know that a metal silo is made up, in its simplest form, by four panels assembled, two by two, by welding on corner posts or between them.
Chaque panneau est obtenu par pliage de tôles et assemblages de façon à ce que ledit panneau présente une section ondulée dont les ondulations sont disposées horizontalement. Each panel is obtained by folding sheets and assemblies so that said panel has a corrugated section whose corrugations are arranged horizontally.
Lorsque le silo est plein, les pressions qui s'exercent sur les parois sont très importantes et, lorsque deux cellules sont accolées et présentent une cloison commune, on a pu constater que même les poteaux communs pouvaient être déformés. When the silo is full, the pressures exerted on the walls are very great and, when two cells are joined and have a common partition, it has been observed that even the common posts could be deformed.
La présente invention propose un procédé simple permettant de renforcer de tels silos. The present invention provides a simple method for reinforcing such silos.
Le procédé de l'invention consiste à fixer un fer plat dans chacun des angles du silo, ledit fer plat étant soudé, par exemple, sur le sommet des ondulations de deux panneaux adjacents. The method of the invention consists in fixing a flat iron in each of the corners of the silo, said flat iron being welded, for example, on the top of the corrugations of two adjacent panels.
De cette façon, on renforce les parois par réduction de portée et on améliore les "encastrements" c'est-à-dire la jonction entre les panneaux et les poteaux. In this way, the walls are strengthened by reducing the range and the "embedding" is improved, that is to say the junction between the panels and the posts.
Le fer plat forme avec les parois du silo un canal vertical, présentant des ouvertures latérales, pouvant être raccordé à sa base à un canal de vidange. Ce canal forme donc un tube de vidange laminaire permettant de supprimer les dispositifs connus utilisés jusqu'ici. En ce qui concerne les tubes de vidange laminaire on pourra se reporter utilement au brevet français publié sous le numéro 2600860. The flat iron forms with the walls of the silo a vertical channel, having lateral openings, which can be connected at its base to a drainage channel. This channel therefore forms a laminar drain tube making it possible to eliminate the known devices used up to now. With regard to the laminar drain tubes, reference may usefully be made to the French patent published under the number 2600860.
II ressort des explications ci-dessous que le fer plat, objet du procédé, permet de remplir deux fonctions qui jusqu'à présent n'avaient aucun lien entre elles. It emerges from the explanations below that the flat iron, object of the process, makes it possible to fulfill two functions which hitherto had no link between them.
L'invention sera mieux comprise par la description qui va suivre faite en se référant aux dessins annexés, à titre d'exemple indicatif seulement, sur lesquels
-la figure 1 est la vue de dessus d'un silo conforme à l'invention:
-la figure 2 est une vue partielle, en perspective, montrant l'angle interne d'un silo;
-la figure 3 est une vue en coupe, partielle et à plus grande échelle, effectuée selon la ligne 111-111 de la figure 1;
-la figure 4 est la vue de dessus de la figure 3.The invention will be better understood from the description which follows, given with reference to the accompanying drawings, by way of indicative example only, in which
FIG. 1 is the top view of a silo according to the invention:
FIG. 2 is a partial perspective view showing the internal angle of a silo;
FIG 3 is a sectional view, partial and on a larger scale, taken along line 111-111 of Figure 1;
FIG. 4 is the top view of FIG. 3.
En se reportant aux dessins et selon un mode de réalisation, on voit que le silo est constitué par l'assemblage, sur des poteaux d'angle 1 ,de quatre panneaux métalliques 2
De la façon connue, chaque panneau est constitué, dans sa forme la plus simple, par une tôle pliée de façon à présenter des ondulations horizontales à section trapézoïdale.Referring to the drawings and according to one embodiment, it can be seen that the silo is constituted by the assembly, on corner posts 1, of four metal panels 2
In known manner, each panel is constituted, in its simplest form, by a sheet folded so as to have horizontal corrugations with trapezoidal section.
Le procédé de l'invention consiste à fixer dans chacun des angles du silo un fer plat 3, ou analogue. De préférence les bords verticaux du fer 3 sont soudés sur les sommets 2a des ondulations des panneaux. Comme cela ressort des dessins et lorsque le silo présente une base carrée, chaque fer 3 forme un angle de 45" avec chacun des panneaux sur lequel il est fixé. The method of the invention consists in fixing in each of the angles of the silo a flat iron 3, or the like. Preferably the vertical edges of the iron 3 are welded to the vertices 2a of the corrugations of the panels. As is apparent from the drawings and when the silo has a square base, each iron 3 forms an angle of 45 "with each of the panels on which it is fixed.
Le fer 3 forme, en coopération avec deux panneaux adjacents, un canal 4, à section triangulaire, présentant des ouvertures latérales 5. The iron 3 forms, in cooperation with two adjacent panels, a channel 4, of triangular section, having lateral openings 5.
Un tel canal, s'il est raccordé à la base du silo à une canalisation d'évacuation, peut avantageusement être utilisé pour la vidange du silo selon la technique connue du tube de vidange laminaire. Such a channel, if it is connected at the base of the silo to an evacuation pipe, can advantageously be used for emptying the silo according to the known technique of the laminar emptying tube.
Le fer 3, outre sa fonction de renfort, permet donc de faire l'économie d'un tube de vidange laminaire tel que décrit, par exemple dans le brevet français publié sous le N" 2600860. The iron 3, in addition to its reinforcing function, therefore makes it possible to save on a laminar drain tube as described, for example in the French patent published under No. 2600860.
Selon une caractéristique de l'invention et pour assurer la reprise des efforts horizontaux, des goussets 6 de renfort sont fixés, de préférence par soudage, dans les creux des ondulations et disposés à l'extérieur des panneaux. According to a characteristic of the invention and to ensure the recovery of horizontal forces, reinforcing gussets 6 are fixed, preferably by welding, in the hollows of the corrugations and arranged outside the panels.
Selon une autre caractéristique de l'invention et pour assurer la reprise des efforts verticaux, notamment à la partie inférieure du silo, il est prévu de renforcer ie fer plat 3 , pour s'opposer à son flambage, au moyen de renforts verticaux 7. According to another characteristic of the invention and to ensure the recovery of vertical forces, in particular at the bottom of the silo, provision is made to reinforce ie flat iron 3, to oppose its buckling, by means of vertical reinforcements 7.
Selon un mode de réalisation, chaque renfort peut être constitué par un fer profilé, à section en L, soudé par l'extrémité de ses ailes contre le fer 3 disposé à l'intérieur du canal 4. According to one embodiment, each reinforcement can be constituted by a profiled iron, with an L-shaped section, welded by the end of its wings against the iron 3 placed inside the channel 4.
