Description

-I- L'invention concerne une structure de puits en matière plastique,-I- The invention relates to a plastic well structure,

comprenant un logement qui possède à la partie inférieure un fond d'appui, et à la partie supérieure une ouverture d'accès, de même qu'un couvercle pour fermer l'ouverture d'accès, le logement  comprising a housing which has a support bottom at the bottom, and an access opening at the top, as well as a cover for closing the access opening, the housing

étant renforcé au moyen d'au moins une nervure circonférentielle.  being reinforced by means of at least one circumferential rib.

Une telle structure de puits est connue de WO-A-9748859. La structure de puits est destinée à être encastrée dans le sous-sol, de façon que l'ouverture d'accès avec couvercle  Such a well structure is known from WO-A-9748859. The well structure is intended to be embedded in the basement, so that the access opening with cover

vienne se placer dans le plan du pavage.  come and place yourself in the plane of the paving.

Selon le lieu d'implantation, la structure de puits peut être exposée à des charges plus ou moins grandes, en particulier des charges provenant de la circulation. L'objectif de  Depending on the location, the well structure may be exposed to more or less large loads, in particular loads from traffic. The objective of

l'invention est de fournir une structure de puits résistant mieux à de telles charges.  the invention is to provide a well structure which better withstands such loads.

Cet objectif est atteint en ce que le logement possède aussi des nervures de soutènement s'étendant entre le fond d'appui et l'ouverture d'accès, et coupant ou croisant  This objective is achieved in that the housing also has support ribs extending between the support base and the access opening, and cutting or crossing

les nervures circonférentielles.the circumferential ribs.

La combinaison des nervures circonférentielles et des nervures verticales fournit une résistance à ce point élevée, que même le matériau plastique ne cède pas et est capable de supporter les charges de la circulation. En particulier, les nervures de soutènement peuvent former un ensemble avec le logement, et, de préférence, elles font saillie vers l'extérieur, en offrant une coupe transversale en forme de V. Les nervures de soutènement peuvent s'étendre entre un appui pour le couvercle s'étendant autour de l'ouverture d'accès, et le fond. En raison de la solidité requise, le fond  The combination of the circumferential ribs and the vertical ribs provides such a high resistance, that even the plastic material does not yield and is able to support the traffic loads. In particular, the retaining ribs can form an assembly with the housing, and, preferably, they project outwards, offering a V-shaped cross section. The retaining ribs can extend between a support for the cover extending around the access opening, and the bottom. Due to the required strength, the bottom

peut posséder un panneau bombé vers l'extérieur.  may have a curved panel to the outside.

Le couvercle peut présenter un panneau bombé vers l'extérieur, entouré d'un bord  The cover may have an outwardly curved panel, surrounded by an edge

d'appui, qui peut s'appuyer sur le logement, autour de l'ouverture d'accès de celui-ci.  support, which can be supported on the housing, around the access opening thereof.

Dans une forme d'exécution particulièrement robuste, le couvercle est à double paroi, et possède un panneau extérieur de même qu'un panneau intérieur bombés vers l'extérieur. Le panneau bombé intérieur s'étend jusque dans l'ouverture d'accès du logement. Les deux panneaux bombés du couvercle sont rattachés réciproquement dans la partie qui se trouve à l'intérieur du bord d'appui. La liaison entre les panneaux bombés du couvercle peut être réalisée de différentes façons, par exemple au moyen de cloisons. On préférera une forme d'exécution, dans laquelle le panneau bombé intérieur a au moins une saillie creuse qui s'étend jusqu'au panneau bombé extérieur. Les saillies peuvent être  In a particularly robust embodiment, the cover is double walled, and has an outer panel as well as an inner panel curved outward. The interior curved panel extends into the access opening of the housing. The two curved panels of the cover are reciprocally attached in the part which is inside the support edge. The connection between the curved panels of the cover can be achieved in different ways, for example by means of partitions. An embodiment is preferred, in which the inner curved panel has at least one hollow projection which extends to the outer curved panel. The protrusions can be

coniques, la pointe du cône étant rattachée au panneau bombé extérieur.  conical, the tip of the cone being attached to the curved exterior panel.

La figure 6 montre une vue en plan, partiellement en coupe, de la pièce de  Figure 6 shows a plan view, partially in section, of the part

rehaussement de la figure 5.enhancement of Figure 5.

Le logement I de la structure de puits selon l'invention, représenté dans la figure 1, possède à sa base un fond d'appui 2 et à la partie supérieure une ouverture d'accès 3,  The housing I of the well structure according to the invention, shown in FIG. 1, has at its base a support bottom 2 and at the upper part an access opening 3,

entourée d'un appui 4 pour le couvercle 5 (voir figures 3 et 4).  surrounded by a support 4 for the cover 5 (see Figures 3 and 4).

Le logement possède au moins une nervure 6 s'étendant en direction circonférentielle, fournissant de la stabilité à la paroi en matière plastique du logement I.  The housing has at least one rib 6 extending in the circumferential direction, providing stability to the plastic wall of the housing I.

Une telle nervure circonférentielle 6 stabilisante, se trouve également autour du fond 2.  Such a stabilizing circumferential rib 6 is also found around the bottom 2.

Comme représenté à la figure 1, le fond 2 possède un panneau bombé vers l'extérieur, qui peut soutenir le logement 1 de façon stable, par exemple dans une terre  As shown in Figure 1, the bottom 2 has an outwardly curved panel, which can support the housing 1 stably, for example in a ground

sablonneuse.sandy.

Le logement possède en outre des embouts de raccordement 8, sur lesquels des  The housing also has connection end pieces 8, on which

conduites (non représentées) peuvent être raccordées.  pipes (not shown) can be connected.

Selon l'invention, des nervures verticales de soutènement 9 sont prévues, faisant saillie vers l'extérieur par rapport à la paroi 10 du logement.

ont la forme d'un V en coupe transversale, et possèdent des sections plates 11,12.  have the shape of a V in cross section, and have flat sections 11,12.

Les nervures verticales de soutènement 9 s'étendent entre le fond 2 et le bord d'appui 4, de façon à assurer une bonne transmission au sous-sol des forces exercées sur le couvercle. Tel que représenté aux figures 3 et 4, le couvercle possède un panneau 13 bombé vers l'extérieur et à l'intérieur, un panneau 14 bombé vers l'extérieur. Le panneau bombé extérieur 13 est entouré d'un bord d'appui 15 circonférentiel qui, à son tour, est posé sur l'appui 4 (représenté partiellement) du logement I. - 3 - Le panneau bombé intérieur 14 s'étend jusque dans la paroi 10 du logement, et est  The vertical retaining ribs 9 extend between the bottom 2 and the support edge 4, so as to ensure good transmission to the basement of the forces exerted on the cover. As shown in Figures 3 and 4, the cover has a panel 13 curved outwards and inside, a panel 14 curved outwards. The outer curved panel 13 is surrounded by a circumferential support edge 15 which, in turn, is placed on the support 4 (partially shown) of the housing I. - 3 - The inner curved panel 14 extends as far as the wall 10 of the housing, and is

entouré d'un anneau 16, qui s'adapte avec un certain jeu dans cette paroi 10.  surrounded by a ring 16, which fits with a certain clearance in this wall 10.

Au moyen de saillies coniques 17, qui sont constituées sous la forme d'un ensemble dans le panneau bombé intérieur 14, les deux panneaux 13, 14 sont rattachés solidement l'un à l'autre. Le module de rehaussement représenté aux figures 5 et 6 possède aussi un appui 4 pour un couvercle, des nervures circonférentielles 6, de même que des nervures verticales  By means of conical projections 17, which are formed as an assembly in the inner curved panel 14, the two panels 13, 14 are securely attached to each other. The raising module shown in Figures 5 and 6 also has a support 4 for a cover, circumferential ribs 6, as well as vertical ribs
