Description

La présente invention est relative à des plaques d'otturatlon, et plus particulièrement à des plaques de couverture conçues de façon à s ap- pliquer sur une embase scellée dans le béton, délimitant l'ouverture à obturer. Parmi les applications possibles de cette invention, on peut citer notamment la couverture de trous d'homme, de canalisations ou tranchées de tout type, par exemple : canalisations électriques, chambres téléphoniques pour les télécommunications, etc. The present invention relates to otturatlon plates, and more particularly to cover plates designed so as to be applied to a base sealed in concrete, delimiting the opening to be closed. Among the possible applications of this invention, there may be mentioned in particular the covering of manholes, pipes or trenches of any type, for example: electrical pipes, telephone rooms for telecommunications, etc.

On connaît de nombreux exemples de réalisation de plaques de cou verture d'orifices, notamment en vue des applications mentionnées ci-dessu
Le problème le plus difficile à résoudre est celui du positionnement de la plaque sur l'orifice, qui doit être facile à réaliser et suffisamment précis pour obtenir une cote constante de la plaque par rapport à embase sur laquelle elle repose, cette plaque devant être en outre au meme niveau que le sol. Par ailleurs, le positionnement de la plaque sur son embase doit assur un blocage de cette plaque s'opposant à tout déplacement de celle-ci par rap port à l'emba se.
Numerous examples are known of the production of cover plates for orifices, in particular with a view to the applications mentioned above.
The most difficult problem to solve is that of positioning the plate on the orifice, which must be easy to perform and precise enough to obtain a constant dimension of the plate relative to the base on which it rests, this plate having to be in in addition to the same level as the ground. Furthermore, the positioning of the plate on its base must ensure a blocking of this plate opposing any movement of the latter relative to the base.

Parmi les solutions actuellement connues, on peut citer, en parti culer - les plaques de couverture comportant uniquement des appuis horizontaux
De telles plaques présentent l'inconvénient de "boiter" par rapport à l'embase - les plaques de couverture dont les appuis sont constitués par des surface
présentant des pentes proches de la verticale. Ces plaques peuvent, sou
la charge, s'enfoncer dans le cadre qui les reçoit, et leur enlèvement
peut s'avérer difficile.
Among the solutions currently known, there may be mentioned, in part culer - the cover plates comprising only horizontal supports
Such plates have the disadvantage of "limping" relative to the base - the cover plates whose supports are constituted by surfaces
with slopes close to the vertical. These plates can, sou
load, sink into the frame that receives them, and remove them
can be difficult.

La présente invention se propose d'apporter une plaque de couverture essentiellement remarquable par la forme originale de ses appuis. Se lon cette invention, chacun des appuis de positionnement de la plaque pré
sente un profil à double géométrie, qui comprend : une pente droite, incline
de quelques degrés par rapport à la verticale, et une partie circulaire qui prolonge et termine ladite pente droite. Grâce à cette combinaison de géométries, on obtient un positionnement de la plaque sur ses appuis qui est à
la fois proche de la verticale (par la pente inclinée) et de l'horizontale (par
la pente circulaire).
The present invention proposes to provide a cover plate essentially remarkable for the original shape of its supports. According to this invention, each of the positioning supports of the pre plate
feels a double geometry profile, which includes: a straight slope, inclines
a few degrees from the vertical, and a circular part which extends and ends the said straight slope. Thanks to this combination of geometries, we obtain a positioning of the plate on its supports which is
both close to the vertical (by the inclined slope) and to the horizontal (by
the circular slope).

Selon une autre caractéristique de cette invention, ladite pente droite est inclinée d'un angle de l'ordre de 20C par rapport à la verticale. According to another characteristic of this invention, said straight slope is inclined at an angle of the order of 20C relative to the vertical.

D'autres caractéristiques et avantages de cette invention ressortiront de la description faite ci-après, en référence aux dessins annexés, qui en illustrent un exemple de réalisation dépourvu de tout caractère limitatif. Other characteristics and advantages of this invention will emerge from the description given below, with reference to the appended drawings, which illustrate an embodiment thereof devoid of any limiting character.

Sur ies dessins:
- la Figure 1 est une vue en coupe longitudinale dlune plaque de couverture selon l'invention, positionnée dans son cadre
- la Figure 2 est une vue en perspective d'une plaque de couverture selon l'invention;
- la Figure 3 représente, en perspective, une embase délimitant le cadre de l'orifice devant recevoir la plaque de couverture selon la Figure 2;eut
- les Figures 4 et 5 sont des vues partielles illustrant les formes des appuis de positionnement prévus dans le cadre.
On the drawings:
- Figure 1 is a longitudinal sectional view of a cover plate according to the invention, positioned in its frame
- Figure 2 is a perspective view of a cover plate according to the invention;
- Figure 3 shows, in perspective, a base defining the frame of the orifice to receive the cover plate according to Figure 2;
- Figures 4 and 5 are partial views illustrating the shapes of the positioning supports provided in the frame.

En se référant au dessin, on voit que les plaques de couverture 10 selon l'invention sont conçues de manière à venir se positionner, par encastrement, dans une embase 12, généralement scellée dans le béton, dont le cadre délimite l'orifice devant être obturé par les plaques 10. Ces plaques peuvent être réalisées de fonderie (acier moulé, fonte GS, fonte grise, tous alliages), ou par tout autre moyen (par exemple : mécano-soudure, béton armé ou béton moulé). Referring to the drawing, it can be seen that the cover plates 10 according to the invention are designed so as to be positioned, by embedding, in a base 12, generally sealed in concrete, the frame of which delimits the orifice to be closed by plates 10. These plates can be made of foundry (cast steel, cast iron GS, gray cast iron, all alloys), or by any other means (for example: mechanical welding, reinforced concrete or molded concrete).

Selon l'invention, la plaque 10 se caractérise par la forme originale de ses quatre appuis, tels que 14, 14', 14" (Fig. 2). Le profil de chaque appui (Fig. 1) présente une double géométrie - d'une part, une pente droite P, inclinée d'un angle < par rapport à la
verticale, par exemple de l'ordre de 20" - d'autre part, une partie circulaire R, qui prolonge et termine la partie P.
According to the invention, the plate 10 is characterized by the original shape of its four supports, such as 14, 14 ', 14 "(Fig. 2). The profile of each support (Fig. 1) has a double geometry - d on the one hand, a straight slope P, inclined at an angle <with respect to the
vertical, for example of the order of 20 "- on the other hand, a circular part R, which extends and ends the part P.

Bien entendu, le cadre 10 de l'embase comporte des appuis 16, 16t de forme correspondante à celle des appuis de la plaque de couverture 10, pour réaliser l'emboftement (Fig. 1). La forme de ces appuis 16, 161 est visible sur les Figures 4 et 5. Of course, the frame 10 of the base has supports 16, 16t of shape corresponding to that of the supports of the cover plate 10, to make the socket (Fig. 1). The shape of these supports 16, 161 is visible in Figures 4 and 5.

Grâce à l'invention, on obtient un appui des plaques 10 sur le cadre qui évite tout boitement, chaque plaque venant naturellement se centrer dans la pente des appuis. Thanks to the invention, one obtains a support of the plates 10 on the frame which prevents any limping, each plate naturally coming to center in the slope of the supports.

Comme on 11a précisé ci-dessus, la combinaison de géométries du profil de chaque appui (pente P + rayon de la partie circulaire R) permet d'obtenir un positionnement de la plaque dans son embase qui est proche de la verticale (pente P), et également proche de l'horizontale (rayon R), sans toutefois atteindre ces deux plans (vertical et horizontal), ce qui évite aux plaques de se bloquer dans l'embase 12 ou de boiter par rapport aux appuis. As 11a specified above, the combination of geometries of the profile of each support (slope P + radius of the circular part R) makes it possible to obtain a positioning of the plate in its base which is close to the vertical (slope P) , and also close to the horizontal (radius R), without however reaching these two planes (vertical and horizontal), which prevents the plates from jamming in the base 12 or limping with respect to the supports.

On obtient ainsi une plaque qui est positionnée et maintenue dans son cadre dans trois directions 1 - horizontalement, par le blocage latéral réalisé par les pentes P des appuis 2 - verticalement, par le blocage en hauteur obtenu par les rayons R des appui 3 - à l'encontre des déplacements en bascule (mouvement intermédiaire entre
le plan vertical et le plan horizontal), par le blocage obtenu par la combi
naison des géométries pente P + rayon R.
A plate is thus obtained which is positioned and held in its frame in three directions 1 - horizontally, by the lateral blocking produced by the slopes P of the supports 2 - vertically, by the height blocking obtained by the radii R of the supports 3 - to against rocking movements (intermediate movement between
the vertical plane and the horizontal plane), by the blocking obtained by the combi
origin of the slope P + radius R geometries

Parmi les avantages apportés par l'invention, on peut citer notamment - un excellent blocage latéral (voir ci-dessus), permettant cependant un dé
montage vertical facile, ce qui n'est pas le cas avec des plaques de type
connu, comportant des appuis constitués uniquement de pentes très proches
de la verticale, pour éviter tout déplacement en bascule des plaques par
rapport au cadre de l'embase - un positionnement précis en hauteur, grâce au rayon R des appuis, permet
tant une régularité de forme de la plaque par rapport au cadre et au niveau
du sol - un parfait silence de fonctionnement, les plaques ne pouvant pas se déplacer
dans leur embase sous l'effet d'une charge, par exemple lors du passage
d'un véhicule.
Among the advantages brought by the invention, one can quote in particular - an excellent lateral blocking (see above), allowing however a dice
easy vertical mounting, which is not the case with type plates
known, including supports consisting only of very close slopes
from the vertical, to avoid any tilting of the plates by
compared to the base frame - precise positioning in height, thanks to the radius R of the supports, allows
both regularity of shape of the plate with respect to the frame and the level
from the ground - perfect operating silence, the plates cannot move
in their base under the effect of a load, for example during the passage
of a vehicle.

I1 demeure bien entendu que cette invention n'est pas limitée à l'exemple de réalisation, ni aux divers exemples d'application mentionnés ou décrits ici, mais qu'elle en englobe toutes les variantes  It remains to be understood that this invention is not limited to the exemplary embodiment, nor to the various examples of application mentioned or described here, but that it encompasses all variants thereof.
