Abstract
Description
L'étaiement de tranchées par des panneaux métalliques de grande surface est d'un usage tout à fait courant et de nombreuses réalisations existent sur le marché. The shoring of trenches with large metal panels is a very common use and many achievements exist on the market.
La présente invention se propose d'apporter des améliorations dans la résistance
et une plus grande facilité de réalisation de ces panneaux.The present invention proposes to provide improvements in strength
and greater ease of making these panels.
Dans l'art antérieur, de nombreux panneaux sont réalisés avec des profilés en C placés horizontalement, empilés les uns sur les autres et soudés ensemble par soudure en continu.In the prior art, many panels are produced with C profiles placed horizontally, stacked on each other and welded together by continuous welding.
Dans d'autres brevets, Krings par exemple, il est déjà fait appel à la soudure par points toutefois, les diverses techniques préconisées montrent que le pro
blème n'est pas résolu avec simplicité, car on retient toujours l'idée d'un cadre, dont la dimension sera variable sur lequel sera soudée une tôle externe, notamment par points.In other patents, Krings for example, spot welding is already used, however, the various techniques recommended show that the pro
problem is not solved with simplicity, because we always retain the idea of a frame, the dimension of which will be variable on which will be welded an external sheet, in particular by points.
Dans la présente invention, une seule pièce sera fabriquée en grande série.In the present invention, a single piece will be mass produced.
La planche unlque montre une vue perspective en extrémité d'un panneau où sont apparents l'empilage des u et le passage du renfort vertical.The plank unlque shows a perspective view at the end of a panel where the stacking of the u and the passage of the vertical reinforcement are visible.
Il s'agit d'une tôle profilée en forme de u dont chaque aile a la particularité de présenter un étranglement proche de l'âme, étranglement dont la dimension correspond à celle de l'épaisseur des ailes du U. It is a u-shaped profiled sheet, each wing of which has the distinction of having a constriction close to the core, a constriction whose dimension corresponds to that of the thickness of the wings of the U.
Ainsi, les U pourront s'emboîter les uns après les autres: les ailes du U 1 seront placées dans l'étranglement 2 si bien que les ailes 1 sont rigoureusement dans le même plan que les ailes 3.Thus, the U can fit together one after the other: the wings of the U 1 will be placed in the constriction 2 so that the wings 1 are strictly in the same plane as the wings 3.
Sur le plan de la résistance, la surépaisseur entre 1 et 2 sera très bénéfi
que, y compris en renforcement contre les chocs.In terms of strength, the extra thickness between 1 and 2 will be very beneficial
that, including reinforcement against shocks.
L'espace laissé entre les ailes du u est suffisant pour que la soudure continue externe par apport utilisée dans l'art antérieur puisse avantageusement être remplacée par des soudures continues à la molette ou par points. Dans ce dernier cas non étanche, la corrosion sera évitée par injection de résine à expanser ou choix de métaux pourvus d'orlgine d'une protection anti-corrosion. The space left between the wings of the u is sufficient for the external continuous weld by contribution used in the prior art to be advantageously replaced by continuous welds with the thumb wheel or by spots. In the latter non-waterproof case, corrosion will be avoided by injection of foaming resin or choice of metals provided with an anti-corrosion protection.
Une autre méthode avantageuse pour souder ensemble deux U 8 et 9 sera une soudure par point d'un seul côté avec apport de métal ; lors de la fusion et à l'aide de ce métal d'apport 10 les deux tôles se souderont l'une à l'autre comme le montre la figure 3.Another advantageous method for welding two U 8 and 9 together will be a spot weld on one side with the addition of metal; during the melting and using this filler metal 10 the two sheets will weld to each other as shown in FIG. 3.
Cet empilage de U avec les superpositions des tôles en 1 et 2 est même très favorable pour un collage par des réslnes, expansées par exemple, appropriées.This stacking of U with the superpositions of the sheets at 1 and 2 is even very favorable for bonding by means of suitable, expanded, for example.
S'il est nécessaire de renforcer verticalement ces panneaux par leur intérieur, ce sera facile à réaliser en incorporant des tubes 7 comme cela est déjà connu.If it is necessary to vertically reinforce these panels from their interior, this will be easy to achieve by incorporating tubes 7 as is already known.
L'âme du U sera perforée d'autant de trous que l'on aura choisi de faire passer de tubes. En dernier effet, les tubes plus les u forment un panneau très rigide, mais très léger.The core of the U will be perforated with as many holes as we have chosen to pass tubes. Finally, the tubes plus the u form a very rigid, but very light panel.
Dans le blindage de tranchée, la finition du haut du panneau a une extrème importance notamment contre les choes. L'étranglement du u sera alors utilisé pour y placer une tôle profilée 4 de forme correspondante.In the trench armor, the finish of the top of the panel is extremely important especially against the choes. The throat of the u will then be used to place a profiled sheet 4 of corresponding shape.
Le bas du panneau pourra être terminé par un tranchant ou tout simplement par un profilé de fermeture 6.The bottom of the panel can be finished with a cutting edge or simply with a closing profile 6.
Le panneau sera terminé latéralement de manière connue en soi.The panel will be finished laterally in a manner known per se.
L'une des faces pourra recevoir, fixée par tout moyen connu en soi, les montant verticaux d'étaiement (non représenté). One of the faces can receive, fixed by any means known per se, the vertical shoring amounts (not shown).
