Abstract

L'invention concerne un dispositif permettant le liaisonnement rapide des plaques de polyéthylène destinées à assurer la protection des canalisations enterrées. Ce dispositif est constitué de « 2 vis » avec leurs écrous et de 2 barrettes de liaison dans le cas des plaques posées bout à bout. Ce dispositif constitué constitué de 2 vis avec écrous permet le liaisonnement des 2 plaques superposées. Cet ensemble lorsqu'il est mis en place et verrouillé sur les plaques de polyéthylène assure non seulement la continuité de la protection mais également une résistance importante à l'ensemble ainsi constitué.The invention relates to a device for rapid bonding of polyethylene sheets intended to ensure the protection of buried pipes. This device consists of "2 screws" with their nuts and 2 connecting bars in the case of plates laid end to end. This device consisting of 2 screws with nuts allows the bonding of the two superimposed plates. This set when it is set up and locked on the polyethylene plates ensures not only the continuity of the protection but also a significant resistance to the assembly thus formed.

Description

- DISPOSITIF DE LIAISONNEMENT DE PLAQUES DE POLYETHYLENE L'invention concerne un dispositif de liaisonnement de plaques de polyéthylène destiné à assurer la protection des canalisations enterrées. Lors de la pose des plaques de polyéthylène en tranchée, il s'avère nécessaire de liaisonner ces plaques entre-elles afin d'assurer une protection mécanique continue au dessus de la canalisation de transport de fluide. Ces protections sont placées entre 30 et 50 centimètres au dessus de la canalisation. L'engin de terrassement qui réalise une fouille dans le sol atteindra ces plaques et ne pourra accrocher la canalisation sans détériorer l'ensemble des plaques liaisonnées entre-elles. The invention relates to a device for bonding polyethylene sheets intended to ensure the protection of buried pipelines. When laying the polyethylene plates in trench, it is necessary to bond these plates together to provide continuous mechanical protection above the fluid transport line. These protections are placed between 30 and 50 centimeters above the pipe. The earth-moving machine which carries out a search in the ground will reach these plates and will not be able to hang the pipe without damaging all the plates bonded together.

Le but de l'invention est de fournir un liaisonnement assurant la continuité de la protection et une résistance mécanique suffisante permettant lors du soulèvement de cette protection par une pelle mécanique de ne pas se rompre et ainsi d'éviter un accrochage de la conduite enterrée. Le dispositif de fixation est composé de six éléments : - Deux « vis » (fig.1) - Deux « écrous » (fig.2) - Deux barrettes percées (fig.3) Montage de l'ensemble : 1. Insérer les deux vis dans une barrette jusqu'à ce que la partie inférieure de la tête vienne en appui sur la barrette. La partie conique permet un blocage en rotation des vis (fig.4) 2. Ensuite insérer côté inférieur la plaque la vis côté filetage de telle sorte que la partie conique bloque la barrette en position (fig.5). 3. Poser la plaque percée, la vis extérieure entrant dans le percement. Les deux plaques sont juxtaposées (fig.6). 4. Poser la barrette supérieure et bloquer l'ensemble à l'aide de deux écrous en serrant manuellement l'ensemble, deux tours suffisent (fig.7) grâce au filetage à pas rapide. 5. Plaques de 1.25 de large - 2 dispositifs de liaisonnement (fig.8) Plaques de 1.50 de large - 3 dispositifs de liaisonnement. (fig.8) Plaques de 1.80 et 2 m de large - 4 dispositifs de liaisonnement. (fig.9) 6. Résultat des différents essais (fig.10). L'invention a pour but de permettre toutes les possibilités d'assemblages de plaques de protection, soit bout à bout, soit superposées soit pour assurer la pose en courbes avec un décalage des trous de fixation sur les plaques (fig.11 - fig.12 - fig.13). Cette invention permet également de fixer les dispositifs de la détection par la même opération et assure donc un gain de temps lors de la pose de tous ces ensembles (fig.14). Ainsi l'invention permet d'une façon simple sans outillage particulier, d'assembler ou de désassembler les plaques de protection mécanique. Les éléments composant cette invention sont facilement échangeables ; le stockage est très facile et chaque pièce est indépendante. L'ensemble des pièces de l'invention est fabriqué par moulage par injection de polypropylène. - 10/15 - ESSAIS SOCOTEC DU 28 JUIN 2010 ETABLIS ET VISES PAR Mr HOAREAU Yves Contenu de la vérification Assistance aux essais de traction sur des pièces de liaison en matière polyamide Visserie et plaques. Détermination de la valeur de rupture The object of the invention is to provide a bonding ensuring the continuity of the protection and sufficient mechanical strength for the lifting of this protection by a mechanical shovel not to break and thus to avoid snagging of the buried pipe. The fixing device is composed of six elements: - Two "screws" (fig.1) - Two "nuts" (fig.2) - Two pierced bars (fig.3) Assembly of the assembly: 1. Insert the two screw in a bar until the lower part of the head comes to rest on the bar. The conical part allows locking in rotation of the screws (fig.4). 2. Then insert the lower side of the plate the screw on the thread side so that the conical part blocks the bar in position (fig.5). 3. Install the pierced plate, the external screw entering the hole. The two plates are juxtaposed (fig.6). 4. Fit the upper bar and secure the assembly with two nuts by hand tightening the assembly, two turns are sufficient (fig.7) thanks to the fast pitch thread. 5. 1.25 wide plates - 2 bonding devices (fig.8) 1.50 wide plates - 3 bonding devices. (fig.8) Plates 1.80 and 2 m wide - 4 binding devices. (fig.9) 6. Result of the different tests (fig.10). The invention aims to allow all possibilities of assembling protection plates, either end to end or superimposed or to ensure the laying in curves with a shift of the fixing holes on the plates (fig.11 - fig. 12 - fig.13). This invention also makes it possible to fix the detection devices by the same operation and thus saves time during the installation of all these assemblies (FIG. 14). Thus the invention allows a simple way without special tools, to assemble or disassemble the mechanical protection plates. The elements composing this invention are easily exchangeable; storage is very easy and each piece is independent. All the parts of the invention are manufactured by polypropylene injection molding. - 10/15 - SOCOTEC TESTS OF JUNE 28, 2010 ESTABLISHED AND SCORED BY Mr HOAREAU Yves Content of the verification Assistance in tensile tests on polyamide connecting pieces Fasteners and plates.
