Abstract

The beam has a hollow web formed of a rigid element made of composite fiber material and thermohardenable resin. The rigid element is made by continuous filamentary rolling in a machine. Three axles are joined to the element to set the element in a mold.

Description

1 La présente invention concerne une poutre en I rigide dont l'âme creuseThe present invention relates to a rigid I-beam whose hollow core

représente un élément continu en composite fibre et résine thermodurcissable réalisé par enroulement filamentaire Cette invention est une amélioration du brevet français 0402951. L'âme de cette nouvelle technique est composée d'un seul élément continu contrairement au précédent brevet composé de plusieurs éléments .la différence est une économie de 40% sur la fourniture . Les membrures sont en bois comme la plupart des poutres en I sur le marché . Un gros avantage la fabrication industrielle del'âme se Fait en continue sur une machine -0 spéciale d'enroulement filamentaire. les applications sont nombreuses utilisation de poutres dans le bâtiment, poteaux, structure aéronautique et spatiale . La description qui suit est un exemple de fabrication industrielle. La figure 1 représente l'élément continu de l'âme sans les membrures.  This invention is an improvement of the French patent 0402951. The core of this new technique is composed of a single continuous element in contrast to the previous patent composed of several elements. is a saving of 40% on the supply. The frames are made of wood like most I-beams on the market. A big advantage is the industrial manufacturing of the soul is done continuously on a special filament winding machine. the applications are many use of beams in the building, poles, aeronautical and spatial structure. The following description is an example of industrial manufacture. Figure 1 shows the continuous element of the core without the ribs.

15 La figure 2 représente l'ensemble : enroulement filamentaire et dépose avec une machine 3 axes , dans un moule prévu à cet effet. La figure 3 représente la poutre en I avec ses membrures en bois. au préalable l'âme en composite est passé à l'étuvage.. La liaison bois ùcomposite est réalisé par collage. 2 o Tous les travaux qui suivent ne différent pas des finitions pour produits Thermodurcissable.FIG. 2 shows the assembly: filament winding and removal with a 3-axis machine, in a mold provided for this purpose. Figure 3 shows the I-beam with its wooden chords. before the composite core is passed to steaming .. The composite wood connection is made by gluing. 2 o All the following work does not differ from the finishes for Thermosetting products.
