Description

La présente invention concerne un dispositif mécanique per- mettant de maintenir en place un caillebotis métallique sur un profilé. The present invention relates to a mechanical device allowing a metal grating to be held in place on a profile.

La fixation de ces caillebotis est traditionnellement ef- fectuée par une plaquette métallique, une vis à métaux, une bride métallique et un écrou. Le caillebotis étant posé à plat sur ses supports, le montage des éléments de la fixation requiert le travail de deux opérateurs. L'un, placé sous le caillebotis t présente en place la bride et l'écrou. L'autre, placé au-dessus du caillebotis pose la plaquette et lia vis et effectue le serrage de la dite vis. Cette méthode entrains un coût élévé de la main- d'oeuvre. The fixing of these gratings is traditionally carried out by a metal plate, a machine screw, a metal flange and a nut. The grating being laid flat on its supports, the assembly of the fastening elements requires the work of two operators. One, placed under the grating t has the flange and the nut in place. The other, placed above the grating, places the plate and the screw and tightens the said screw. This method entails a high cost of labor.

Le dispositif selon l'invention permet de remédier à cet inconvénient. En effet, l'assemblage des éléments de la fixation sur le caillebotis s'effectue avant la pose de celui-ci sur ses supports et, le caillebotis étant en place sur les poutrelles, un seul opérateur travaillant au-dessus est nécessaire pour serrer la vis. The device according to the invention overcomes this drawback. Indeed, the assembly of the elements of the fixing on the grating is carried out before the installation of this one on its supports and, the grating being in place on the beams, a single operator working above is necessary to tighten the screw.

Les figures I, 2, 3s 4, 5 représentent un dispositif selon l'invention. Figures I, 2, 3s 4, 5 show a device according to the invention.

Les figures 6, 7, 8 9 représentent une variante de ce diepositif. Figures 6, 7, 8 9 show a variant of this diepositif.

La fixation représentée sur les figures 1, 2, 3, 49 5 se compose d'une plaquette métallique (I) posée sur le caillebotis(2). The fixing shown in Figures 1, 2, 3, 49 5 consists of a metal plate (I) placed on the grating (2).

Une via à métaux (3) traversant la plaquette QI) et le caille- botis (2) vient se visser dans une bride métallique taraudée (4) placée sous le caillebotis (2) qui est en appui sur la poutrelle(5)0
Le caillebotis (2) étant posé à plat, par exemple sur des tréteaux, l'utilisateur effectue l'assemblage sur celui-ci de la plaquette (I), de la bride taraudée (4) et de la vis (3) qu'il engage de quelques filets seulement afin que la bride (4) pende au bout de la vis (3); Il s'assure visuellement du bon sens des extremites avant (a, fit 3) et arrière (b, fig 3) de la bride , puis pose le caillebotis (2) sur son support (5) on veillant à ce que la bride (4) soit parallèle à la poutrelle (5).La dernière opéra- tion consiste à serrer la vis (3). A metal via (3) passing through the QI plate) and the grating (2) is screwed into a threaded metal flange (4) placed under the grating (2) which is supported on the beam (5) 0
The grating (2) being laid flat, for example on trestles, the user performs the assembly on the latter of the plate (I), the threaded flange (4) and the screw (3) that it engages only a few threads so that the flange (4) hangs from the end of the screw (3); He visually checks the common sense of the front (a, fit 3) and rear (b, fig 3) ends of the flange, then places the grating (2) on its support (5), making sure that the flange ( 4) or parallel to the beam (5). The last operation consists in tightening the screw (3).

Dès que l'on serre. la vis (3), celle-ci entra@ne en rotation dans le sens des aiguilles d'une montre la bride (4). Cette bride (4), dès le premier quart de tour de la vis (3) voit son extrémité avant (a, fig 3) s'engager sous l'ail. de la poutrelle(5) tandis que l'extrémité arrière (b, fig 3) vient s'appuyer contre la patte verticale de la plaquette (I) ce qui l'arrête on rota@@on.  As soon as we squeeze. the screw (3), the latter rotates in a clockwise direction the flange (4). This flange (4), from the first quarter turn of the screw (3) sees its front end (a, fig 3) engage under the garlic. of the beam (5) while the rear end (b, fig 3) bears against the vertical tab of the plate (I) which stops it on rota @@ on.

Ensuite, lors da vissage la bride (4) monte; sa partie arrière (b, fig 3) s'emboîtant et prenant appui sur deux barres portantes du caillebotis (2), le maintien de l'ensemble caillebotis (2), plaquette (I), bride (4) et profilé (5) est assuré.Then, when screwing the flange (4) goes up; its rear part (b, fig 3) interlocking and bearing on two supporting bars of the grating (2), maintaining the grating assembly (2), plate (I), flange (4) and profile (5) is assured.

Sur la bride (4) la position du trou taraudé permet une juste répartition de la masse de celle-ci de chaque côté de l'axe de la vis (3). On the flange (4) the position of the tapped hole allows a fair distribution of its mass on each side of the axis of the screw (3).

Une variante de ce dispositif selon les figures 6, 7g 8, 9 permet la fixation d'un caillebotis en tôle pliée. Au montage, l'arrêt on rotation de la bride (4) est assuré par une languette métallique verticale (c, fig 9) fixée sur cette bride qui vient en contact avec l'aile du profilé (5). La languette en question peut-être fixée sur la bride (4) par soudure.  A variant of this device according to Figures 6, 7g 8, 9 allows the fixing of a grating in folded sheet. During assembly, the flange (4) is stopped on rotation by a vertical metal tongue (c, fig 9) fixed on this flange which comes into contact with the wing of the profile (5). The tab in question may be fixed to the flange (4) by welding.

Le dispositif selon l'invention est destiné à la fixation de caillebotis utilisés dans les batiments industriels et les ouvrages de génie civil. The device according to the invention is intended for fixing gratings used in industrial buildings and civil engineering works.

La plaquette (I, fig 2) est réalisée en tale d'acier. Elle est constituée en son milieu d'une partie plane percée d'un trou destiné à recevoir une vis à métaux (3). Afin de noyer la tête de cette vis, deux rebords de forme demi-ronde ont été créés. Leur seconde fonction est d'assurer l'appui de la plaquette on chevau- chant deux barres portantes du caillebotis (2). L'un de ces rebords est prolongé verticalement vers le bas et comporte dans sa partie inférieure une échancrure rectangulaire destinée à recevoir la bride (4) avant sa rotation d'un quart de tour.Cette échancrure est bordée par une languette qui, lors du serrage de la vis (3) arrête la bride (4) après une rotation d'un quart de tour. The plate (I, fig 2) is made of steel sheet. It consists in the middle of a flat part pierced with a hole intended to receive a machine screw (3). In order to drown the head of this screw, two half-round edges were created. Their second function is to ensure the support of the plate by overlapping two supporting bars of the grating (2). One of these edges is extended vertically downwards and has in its lower part a rectangular notch intended to receive the flange (4) before its rotation by a quarter of a turn. This notch is bordered by a tongue which, when tightening the screw (3) stops the flange (4) after a quarter-turn rotation.

La vis à métaux (3) peut-etre une vis à te cylindrique fendue, une vis à tête cylindrique six pans creux ou une vis à tête hexagonale.  The machine screw (3) may be a slotted pan head screw, a hexagon socket head cap screw or a hexagonal head screw.

La bride (4 fig 3) est réalisée en fer plat. Elle comporte une partie plane percée en son milieu d'un trou taraudé destine à recevoir la vis à métaux (3). S6n extrémité arrière (b fig 3) est recourbée à l'équerre, vers le haut d'une hauteur sensiblement égale à l'épaisseur de l'aile du profilé (5). De part sa forme, cette extrémité (b fig 3) assure deux fonctions ; un positionnement de la bride (4) sur le caillebotis (2) grâce à deux facette. The flange (4 fig 3) is made of flat iron. It comprises a flat part pierced in the middle of a tapped hole intended to receive the machine screw (3). S6n rear end (b fig 3) is bent at right angles, upwards by a height substantially equal to the thickness of the wing of the profile (5). Due to its shape, this end (b fig 3) performs two functions; positioning of the flange (4) on the grating (2) thanks to two facets.

En variante la bride (4 fig 9) est constituée d'une partie centrale plane percée d'un trou taraudé destiné à recevoir une vis à métaux (3). Cette partie centrale est prolongée vers l'arrière (b fig 9) d'une partie verticale montante terminée par un retour à l'horizontale dans un plan parallèle à la partie centrale. As a variant, the flange (4 fig 9) consists of a flat central part pierced with a tapped hole intended to receive a machine screw (3). This central part is extended towards the rear (b fig 9) by a vertical rising part ending in a return to the horizontal in a plane parallel to the central part.

Vers l'avant (a fig 9), la partie centrale se prolonge d'une partie verticale descendante se terminant par un retour à l'horizontale parallèle à la partie centrale.Towards the front (a fig 9), the central part is extended by a vertical descending part ending in a return to the horizontal parallel to the central part.

La bride (4), dans sa partie avant (a fig 9) descendante comporte une languette métallique verticale soudée débordant sur le côté de la bride et présentant un pli vers l'avant. Au contact de l'aile du profilé (5) cette languette assure l'arrêt en rotation de la bride (4). The downward flange (4), in its front part (a fig 9) has a welded vertical metal tongue extending over the side of the flange and having a fold towards the front. In contact with the wing of the profile (5) this tab ensures the rotation stop of the flange (4).

La hauteur entre les 2 ailes dé la bride (4) correspond sensiblement à l'épaisseur du caillebotis (2) et de l'aile du profilé (5).  The height between the 2 wings of the flange (4) corresponds substantially to the thickness of the grating (2) and the wing of the profile (5).
