Abstract

The beam (1) has a section (10) formed with a composite material. Electric drivers are integrated within the material in form of multiple conducting inserts (20). The section comprises a pre-profiled part formed by pultrusion for placing housings for the inserts. The pre-profiled part is covered with plastic or composite insulation to ensure fire protection. The inserts are placed in a symmetrical way in the section. The composite material is carried out by mixture of inorganic fibers of reinforcements, and a thermoplastic matrix is obtained by reactive way. An independent claim is also included for a method for manufacturing an electrified beam.

Description

Poutre électrifiée. La présente invention concerne une nouvelle utilisation des profilés composites réalisés par pultrusion pour fabriquer des poutres électrifiées.Electrified beam. The present invention relates to a new use of composite profiles made by pultrusion to manufacture electrified beams.

L'idée est de profiter des propriétés isolantes et structurelles des profilés composites réalisés par pultrusion pour fabriquer des poutres à vocation structurelle, non corrosives et pouvant être intrinsèquement électrifiées.The idea is to take advantage of the insulating and structural properties of composite profiles made by pultrusion to make non-corrosive structural purpose beams that can be intrinsically electrified.

Les applications couvrent tous des systèmes devant assurer à la fois une fonction mécanique et une fonction d'électrification, principalement en extérieur où il existe également un besoin de résistance à la corrosion. L'intégration des conducteurs électriques au sein 15 du profilé composite résout également un problème d'étanchéité rencontré dans des systèmes électriques installés en extérieur ou en environnement potentiellement humide. L'invention peut être vue comme une poutre 20 (élément destiné à porter des charges) électrifiée, ou aussi comme un câble électrique rigide et autoporteur. Les systèmes existants sont un mixte d'un matériau qui assure la mécanique mais qui est électriquement conducteur (acier ou aluminium) et d'une isolation 25 plastique. Ces systèmes sont très difficilement utilisables en extérieur ou milieux humide car l'étanchéité de tels systèmes est très délicate et onéreuse dans la mesure ou ces systèmes présentent nécessairement des zones ouvertes 30 permettant d'accéder aux éléments conducteurs sans percer le matériaux porteur conducteur.The applications all cover systems that must provide both a mechanical function and an electrification function, mainly outdoors where there is also a need for corrosion resistance. The integration of the electrical conductors within the composite profile also solves a sealing problem encountered in electrical systems installed outdoors or in a potentially humid environment. The invention can be seen as a beam (element for carrying loads) electrified, or also as a rigid and self-supporting electric cable. Existing systems are a combination of a material that provides mechanical but electrically conductive (steel or aluminum) and plastic insulation. These systems are very difficult to use outdoors or wet environments because the sealing of such systems is very delicate and expensive insofar as these systems necessarily have open areas 30 to access the conductive elements without drilling the conductive carrier material.
