Description
Profilé de construction pour châssis d'armoire électrique
L'invention porte sur un profilé de construction pour châssis d'armoire, notamment d'armoire électrique, destiné à former un montant vertical du châssis.Construction profile for electrical cabinet chassis
The invention relates to a construction profile for a cabinet chassis, in particular an electrical cabinet, intended to form a vertical upright of the chassis.
Un tel profilé est connu du document
FR 2 682 257. La figure 1 représente en perspective ce profilé connu 1' qui est creux.Such a profile is known from the document
FR 2 682 257. Figure 1 shows in perspective this known profile 1 'which is hollow.
Dans la construction électrique, il est courant d'installer les équipements et les appareillages dans des armoires électriques. In electrical construction, it is common to install equipment and devices in electrical cabinets.
Ces armoires sont souvent réalisées à l'aide de profilés métalliques tel que celui de la figure 1 formant une charpente sur laquelle on fixe les équipements et appareillages. These cabinets are often produced using metal profiles such as that of FIG. 1 forming a frame on which the equipment and apparatus are fixed.
On vient par la suite poser des panneaux et des portes autour de cette charpente. We then come and put panels and doors around this frame.
Le but de l'invention est de perfectionner la structure des profilés connus comme celui du document
FR 2 682 257 de manière à satisfaire les conditions suivantes
- rigidité du profilé tout en utilisant une quantité de matière réduite ;
- possibilité de réaliser des jonctions facilement assemblables avec des traverses horizontales joignant les angles de l'armoire, tout en garantissant une rigidité de la charpente ;
- possibilité d'offir des plans de poses permettant de fixer aisément les supports d'équipements et d'appareillages
- possibilité d'utiliser un pilier unique commun à plusieurs structures adjacentes ;
- possibilité de réaliser ce profilé en tôle prérevêtue, poinçonnée, cisaillée et pliée, sans arrête coupante pouvant blesser un utilisateur.The object of the invention is to improve the structure of the profiles known as that of the document
FR 2 682 257 so as to satisfy the following conditions
- stiffness of the profile while using a reduced amount of material;
- possibility of making easily assembled junctions with horizontal crosspieces joining the corners of the cabinet, while ensuring rigidity of the frame;
- possibility of offering poses plans allowing to easily fix the supports of equipment and apparatuses
- possibility of using a single pillar common to several adjacent structures;
- possibility of making this profile in pre-coated sheet metal, punched, sheared and folded, without a cutting edge which could injure a user.
A cet effet, l'invention a pour objet un profilé de construction pour châssis d'armoire, caractérisé en ce que le profilé présente une section en forme de losange ayant des angles prolongés chacun par une aile. To this end, the invention relates to a construction profile for cabinet chassis, characterized in that the profile has a diamond-shaped section having angles each extended by a wing.
Un tel profilé creux ou non répond à toutes les exigences énumérées précédemment. Such a hollow profile or not meets all the requirements listed above.
L'invention est maintenant décrite en détail cidessous en référence aux dessins. The invention is now described in detail below with reference to the drawings.
La figure 1 est une vue schématique en perspective d'un profilé creux connu. Figure 1 is a schematic perspective view of a known hollow section.
La figure 2 est une vue en coupe transversale du profilé selon l'invention. Figure 2 is a cross-sectional view of the profile according to the invention.
La figure 3 est une vue de dessus en coupe d'une partie d'une armoire dont les montants du châssis sont formés par un profilé selon l'invention. Figure 3 is a top view in section of a part of a cabinet whose frame amounts are formed by a profile according to the invention.
Sur la figure 2, le profilé 1, par exemple métallique, présente en section transversale par rapport à son axe longitudinal, un noyau central 2 évidé ou non de forme losangique, aux angles duquel se trouvent quatre ailes 3. In FIG. 2, the section 1, for example metallic, has in cross section with respect to its longitudinal axis, a central core 2, hollow or not, of diamond shape, at the angles of which are four wings 3.
Cette section a approximativement la forme d'une étoile à quatre branches dont deux branches adjacentes s'étendent perpendiculairement l'une par rapport à l'autre. This section is roughly in the shape of a four-pointed star, two adjacent branches of which extend perpendicularly to each other.
La présence de quatre ailes 3 et l'utilisation d'une structure fermée apporte suffisamment de rigidité aussi bien en torsion qu'en flexion pour permettre la réalisation de ce profilé en tôle d'épaisseur réduite jusqu'à 1 mm lorsqu'il s'agit de supporter des charges conventionnelles. The presence of four wings 3 and the use of a closed structure provides sufficient rigidity both in torsion and in bending to allow the realization of this sheet metal profile of reduced thickness up to 1 mm when it acts to support conventional loads.
Comme visible sur la figure 2, la structure fermée du profilé est facilement réalisable par pliage bord à bord en 8 d'une tôle. As shown in Figure 2, the closed structure of the profile is easily achievable by folding edge to edge in 8 of a sheet.
Deux traverses horizontales peuvent facilement être assemblées à angle droit sur le profilé 1 comme visible sur la figure 3 pour former une partie de charpente d'armoire. Two horizontal crosspieces can easily be assembled at right angles to the profile 1 as visible in FIG. 3 to form a part of the frame of the cabinet.
Chaque traverse peut être solidarisée à deux ailes du profilé, mais une amélioration peut être apportée en plaçant une seule vis 15 commune à deux traverses 10, 10"' dans un plan joignant le meilleur des deux côtés du noyau du profilé. Each cross can be secured to two wings of the profile, but an improvement can be made by placing a single screw 15 common to two cross 10, 10 "'in a plane joining the best on both sides of the core of the profile.
L'écrasement du profilé lors du serrage de cette vis est empêché dans ce cas par le remplissage du centre du noyau au moyen d'une petite pièce métallique 16 (un cylindre) positionnée au niveau de la vis. The crushing of the profile when tightening this screw is prevented in this case by filling the center of the core by means of a small metal part 16 (a cylinder) positioned at the level of the screw.
Cette pièce 16 peut être munie d'un anneau (non représenté), qui permet l'élinguage de l'armoire. This part 16 can be provided with a ring (not shown), which allows the slinging of the cabinet.
Les ailes 3 sont poinçonnées de façon régulière en 5 sur toute la longueur du profilé afin d'y fixer les supports d'appareillages et d'équipements ainsi que les plastrons frontaux. The wings 3 are punched in a regular fashion at 5 over the entire length of the profile in order to fix the supports for apparatus and equipment there as well as the front plates.
Comme visible sur la figure 3, la forme symétrique totale de la section du profilé permet de recevoir trois traverses horizontales de même niveau 10, 10', 10" afin d'étendre la structure en utilisant un pilier commun à plusieurs charpentes. Ce profilé permet d'obtenir un avantage économique et un gain de surface au sol. As shown in Figure 3, the total symmetrical shape of the section of the profile allows to receive three horizontal crosspieces of the same level 10, 10 ', 10 "in order to extend the structure using a common pillar with several frames. This profile allows to obtain an economic advantage and a gain in floor space.
Le profilé peut être réalisé à l'aide d'une seule plaque de tôle pliée de façon telle à obtenir une structure entièrement fermée. On évite ainsi la présence d'arrêtes de cisaillement à l'extérieur du profilé. The profile can be produced using a single sheet metal plate folded so as to obtain a fully closed structure. This avoids the presence of shear stops outside the profile.
