Abstract
Description
La présente invention est relative à un dispositif de protection des poteaux de clôture. Dans le domaine de I 'agriculture et plus particulièrement de l'élevage, on s utilise des poteaux métalliques. Ces poteaux sont protégés de la corrosion ambiante par un traitement de galvanisation. Généralement, les poteaux doivent être démontables, pour permettre aux engins agricoles de pénétrer dans l'enclos. A cet effet, on noie dans un bloc de béton un fourreau dans lequel on peut engager le poteau qui peut, ensuite, être facilement enlevé. The present invention relates to a device for protecting the fence posts. In the field of agriculture and more particularly livestock farming, metal poles are used. These posts are protected from ambient corrosion by galvanizing treatment. Generally, the posts must be removable, to allow agricultural machinery to enter the enclosure. For this purpose, a sleeve is embedded in a concrete block in which the post can be engaged, which can then be easily removed.
La partie supérieure du fourreau arase sensiblement le niveau du sol pour 15 ne pas faire obstacle au passage des engins. The upper part of the sheath substantially level the ground so as not to hinder the passage of the machines.
L'expérience a montré que la protection des poteaux contre la corrosion était insuffisante lorsque ceux-ci étaient utilisés pour former un enclos comportant une couche importante de paille qui se transformait, rapidement, en 20 un fumier particulièrement corrosif. Experience has shown that column protection against corrosion is insufficient when used to form a pen with a large layer of straw which rapidly turns into a particularly corrosive manure.
Le dispositif de l'invention, qui remédie à cet inconvénient, se caractérise par un fourreau, susceptible de s'étendre hors du sol, et dont la partie inférieure s'emmanche dans celle supérieure du fourreau usuel, noyé dans le sol et modifié 25 en conséquence. The device of the invention, which overcomes this disadvantage, is characterized by a sheath, likely to extend out of the ground, and whose lower part engages in the top of the usual sheath, embedded in the ground and modified 25 Consequently.
Selon l'invention, la partie supérieure du fourreau, usuel, est élargie pour permettre l'emmanchement de la partie inférieure d'un autre fourreau, réalisé en 10 une matière plastique inerte, qui s'étend hors du sol sur une hauteur suffisante pour protéger le poteau métallique. According to the invention, the upper part of the usual sheath is widened to allow the fitting of the lower part of another sheath, made of an inert plastic material, which extends out of the ground to a height sufficient to protect the metal pole.
Un avantage de la présente invention réside dans le fait que le même fourreau peut être utilisé soit, en position inférieure, comme organe de guidage du poteau, soit, en position supérieure, comme organe de protection. De cette façon, la fabrication et le stockage sont simplifiés. An advantage of the present invention lies in the fact that the same sleeve can be used either, in the lower position, as a guide member of the pole, or, in the upper position, as a protective member. In this way, manufacturing and storage are simplified.
La présente invention sera mieux comprise par la description qui va suivre 10 faite en se référant au dessin annexé, à titre d'exemple indicatif seulement, sur lequel : The present invention will be better understood from the following description with reference to the accompanying drawing, by way of indicative example only, in which:
-la figure 1 est une vue en coupe verticale d'un fourreau conforme à l'invention ; - la figure 2 est une vue en coupe verticale montrant la mise en oeuvre du dispositif de l'invention ; FIG 1 is a vertical sectional view of a sheath according to the invention; - Figure 2 is a vertical sectional view showing the implementation of the device of the invention;
- la figure 3 est une vue en coupe verticale d'un manchon permettant 20 d'optimiser le résultat obtenu par le dispositif de l'invention. - Figure 3 is a vertical sectional view of a sleeve for optimizing the result obtained by the device of the invention.
En se reportant à la figure 1, on voit que le fourreau 1, se présente sous la forme d'un fourreau tubulaire dont la section correspond, au jeu près, à celle du poteau métallique P. Selon l'invention, la partie supérieure du fourreau 1 présente un élargissement 2 dont le diamètre interne correspond, au jeu près, à celui externe dudit fourreau. 15 25 En se reportant à la figure 2, on voit que le fourreau 1 a est noyé, de la façon usuelle dans un bloc de béton et arase, sensiblement, le sol S. Referring to FIG. 1, it can be seen that the sheath 1 is in the form of a tubular sheath whose section corresponds, with play, to that of the metal post P. According to the invention, the upper part of the sheath 1 has a widening 2 whose inner diameter corresponds, with clearance, to the outer one of said sheath. With reference to FIG. 2, it can be seen that the sheath 1a is embedded, in the usual way, in a concrete block and arase substantially the ground S.
Selon l'invention, on emmanche sur le fourreau 1 a un second fourreau 1 b 5 qui s'étend hors du sol sur une certaine hauteur et l'on engage dans ceux-ci le poteau P usuel. According to the invention, a second sheath 1b 5 is slid over the sheath 1a which extends out of the ground over a certain height and the conventional post is engaged therein.
Avantageusement, les deux fourreaux 1 a et 1 b sont identiques, mais ils pourraient être différents. Advantageously, the two sleeves 1a and 1b are identical, but they could be different.
Chaque fourreau est réalisé à partir d'une matière plastique moulée et pour faciliter le démoulage, celui-ci présente une légère conicité selon son axe longitudinal. Celle-ci est avantageusement utilisée au niveau de l'emmanchement des deux fourreaux pour assurer une bonne étanchéité. Each sheath is made from a molded plastic material and to facilitate demolding, it has a slight taper along its longitudinal axis. This is advantageously used at the fitting of the two sleeves to ensure a good seal.
Ainsi, le diamètre dl de l'extrémité inférieure du fourreau est égal à celui d2 mesuré à une hauteur h de la base de l'élargissement 2, le diamètre inférieur dudit élargissement à sa base étant inférieur à d2 en raison de la conicité précitée. Thus, the diameter d1 of the lower end of the sleeve is equal to that d2 measured at a height h of the base of the enlargement 2, the lower diameter of said enlargement at its base being less than d2 because of the aforementioned conicity.
Normalement, un espace annulaire subsiste entre le poteau P et la partie supérieure du fourreau 1 b. Normally, an annular space remains between the pole P and the upper part of the sheath 1b.
Selon l'invention, cet espace est, avantageusement, obturé par une bague 25 épaulée 3 qui se loge, avec un léger coincement dû à la conicité, entre le poteau et la périphérie interne de l'élargissement 2. Naturellement, le dispositif peut-être utilisé sans bague 10 15 20 De préférence, cette bague est réalisée dans la même matière que celle dont est formée les fourreaux. According to the invention, this space is advantageously closed off by a shoulder ring 3 which is housed, with a slight wedging due to the conicity, between the post and the inner periphery of the enlargement 2. Naturally, the device can This ring is preferably made of the same material as the sleeves are formed.
