Abstract

The firm support for heavy loads on the ground, such as cars and wood stores, has a picket which is cylindrical or square in shape and galvanized and having a galvanized cap which is retained in place to prevent loosening during emplacement. The pickets can be driven in using sliding weight of many kilos. The pickets are cut off at ground level to form the supporting surface.

Description

   Appui économique en terrain meuble pour modules préfabriqués Des charges moyennement lourdes ( < 300 kg par M2) sont régulièrement entreposées sur du terrain résistant par temps chaud et sec qui devient meuble, voir très tendre par temps de pluie ou se déforme après le dégel. C'est le cas pour l'entreposage de bois, de véhicules, de fûts, de stocks ou de modules préfabriqués. 



  La solution consiste le plus souvent à construire une fondation périphériques suffisamment profonde pour dépasser la barrière de gel (80 cm) et de poser dessus des hourdis ou des poutrelles ou encore une dalle épaisse armée. Lorsque le stock a entreposer offre lui-même une surface auto portante cette construction peut se résumer à la construction de longrines ou d'un certain nombre de plots. Ces plots sont construits par terrassement, pose d'un béton maigre et élévation en béton ou en maçonnerie. 



  Ces constructions sont particulièrement onéreuses surtout lorsqu'il s'agit d'appuis provisoires pour une durée de un mois à deux ans par exemple. Ce surcoût grève la valeur du stock entreposé. Une dalle coûte environ 100 Euros par M2 et un plots 80 Euros (valeur en 2.001). Il faut généralement un plot par 5 à 10 M2. 



  Le brevet consiste à remplacer les plots par des piquets galvanisés foncés à refus, surmontés d'une coiffe permettant de recevoir des blocs d'appuis ou des longrines si la marchandise à stocker n'a pas sa propre assise portante. 



  Pour déposer des troncs d'arbre par exemple, il suffit d'un piquet par ¯10 M2, de poser des pièces de bois transversalement sur ces piquets et ensuite les troncs sur ces traverses. 



  Les shelters ou modules préfabriqués les plus répandus font 6M10 (20 pieds) x 2M44 (8 pieds) au sol. En plaçant 3 piquets sur chaque long côtés, soit 6 piquets, il suffit de placer 6 blocs en bois ou en béton et poser l'unité dessus. A raison de 300 Kg par M2, la charge sur un piquet est de 750 Kg. Si un piquet devait s'enfoncer relativement plus, il suffirait de lever cet appuis au cric et d'ajuster une cale. 



  Un piquet revient environ à 10 Euros. Pour cette unité de 6M10 x 2M44 il faut donc 60 Euros (la moitié en fourniture et l'autre moitié en main   d'oeuvre).   Une dalle de 18M2 aurait coûté 1. 800 Euros et six plots en maçonnerie 480 Euros. La solution avec le brevet est donc 8 à 30 fois moins onéreuse. 



  On peut reprocher à la solution par piquet la difficulté d'enfonçage du piquet et son instabilité latérale éventuelle. Le brevet apporte aussi une solution pour l'enfonçage avec une masse coulissante. Quant à la stabilité latérale, elle est généralement peu dangereuse en entreposage temporaire et au plus il faudra augmenter 

 <Desc/Clms Page number 2> 

 proportionnellement le nombre de piquets. Au lieu d'un piquet par 10 M2, on en placera 1 par 3 M2 (ce qui est le cas retenu pour l'unité de 6M10 x 2M44). 



  Un piquet carré au lieu de rond donne une meilleure stabilité latérale. 



  Lors du placement sur grande surface, les piquets intérieurs au périmètre extérieur seront le plus souvent à l'abri de l'eau et du gel ce qui renforcera la stabilité de l'ensemble. 



  Les piquets peuvent être provisoires, il est alors plus facile de prendre des piquets cylindriques. Pour retirer un piquet, il faut le pincer dans un serre joint placer horizontalement et le faire tourner pour supprimer l'adhérence verticale. Le piquet sort ensuite facilement en continuant de tourner, même pour les piquets carrés.

   Economic support in loose ground for prefabricated modules Medium heavy loads (<300 kg per M2) are regularly stored on resistant ground in hot and dry weather which becomes loose, even very tender in rainy weather or deforms after thawing. This is the case for the storage of wood, vehicles, barrels, stocks or prefabricated modules.



  The solution most often consists in building a peripheral foundation deep enough to exceed the frost barrier (80 cm) and to lay on it slabs or beams or a thick reinforced slab. When the stock to be stored itself offers a self-supporting surface, this construction can be summarized as the construction of stringers or a certain number of studs. These studs are built by earthworks, laying of lean concrete and elevation in concrete or masonry.



  These constructions are particularly expensive especially when it comes to temporary supports for a period of one month to two years for example. This additional cost strikes the value of the stock stored. A slab costs around 100 Euros per M2 and a stud 80 Euros (value in 2.001). It generally requires a pad per 5 to 10 M2.



  The patent consists of replacing the studs with dark galvanized refusal stakes, surmounted by a cover making it possible to receive support blocks or sills if the goods to be stored do not have its own bearing seat.



  To deposit tree trunks for example, all you need is one stake per ¯10 M2, to place pieces of wood transversely on these posts and then the trunks on these crosspieces.



  The most common shelters or prefabricated modules are 6M10 (20 feet) x 2M44 (8 feet) on the ground. By placing 3 stakes on each long side, i.e. 6 stakes, just place 6 wooden or concrete blocks and place the unit on it. At a rate of 300 Kg per M2, the load on a stake is 750 Kg. If a stake were to sink relatively more, it would suffice to lift this support with the jack and adjust a wedge.



  A stake costs around 10 Euros. For this 6M10 x 2M44 unit, you therefore need 60 Euros (half for supplies and the other half for labor). An 18M2 slab would have cost 1,800 Euros and six masonry studs 480 Euros. The solution with the patent is therefore 8 to 30 times less expensive.



  One can criticize the solution by stake for the difficulty of sinking the stake and its possible lateral instability. The patent also provides a solution for sinking with a sliding mass. As for lateral stability, it is generally not very dangerous in temporary storage and at most it will be necessary to increase

 <Desc / Clms Page number 2>

 proportionally the number of stakes. Instead of a stake per 10 M2, we will place 1 per 3 M2 (which is the case retained for the unit of 6M10 x 2M44).



  A square stake instead of a round one gives better lateral stability.



  When placing on a large surface, the interior stakes at the outer perimeter will most often be protected from water and frost, which will strengthen the stability of the assembly.



  The stakes can be temporary, so it is easier to take cylindrical stakes. To remove a stake, you have to pinch it in a joint clamp, place it horizontally and rotate it to remove the vertical grip. The stake then comes out easily, continuing to turn, even for square posts.
