Description

La présente invention concerne un élément de construction, notamment en béton, destiné à réaliser des murs de soutènement.The present invention relates to a building element, in particular concrete, for producing retaining walls.

Un tel élément de construction et des murs de soutènement réalisés par la superposition de plusieurs rangées de tels éléments ont été décrits dans la demande de brevet français 2 845 404 au nom du présent déposant.Such a construction element and retaining walls made by the superposition of several rows of such elements have been described in the French patent application. 2,845,404 on behalf of the present applicant.

Dans la réalisation décrite dans cette demande de brevet, chaque élément de construction est destiné à coopérer en superposition avec au moins un élément de construction similaire.In the embodiment described in this patent application, each building element is intended to cooperate in superposition with at least one similar building element.

Chaque élément comporte une face de dessus, une face de dessous, une face avant et une face arrière et au moins deux alvéoles de section allongée débouchant sur la face de dessus et sur la face de dessous, ces deux alvéoles étant alignées sensiblement parallèlement à la face arrière.Each element comprises a top face, a bottom face, a front face and a rear face and at least two elongated section cavities opening on the top face and the bottom face, these two cells being aligned substantially parallel to the back side.

Chaque élément de construction comporte sur sa face de dessous deux crans en saillie pouvant s'engager sensiblement sans jeu dans des alvéoles débouchant sur la face de dessus d'un élément inférieur.Each building element has on its underside two projecting notches that can engage substantially without play in cells opening on the top face of a lower element.

L'emboîtement ainsi créé permet de solidariser les deux éléments et de les décaler l'un par rapport à l'autre dans le sens de leur longueur ainsi que dans le sens transversal.The nesting thus created makes it possible to secure the two elements and to shift them relative to each other in the direction of their length as well as in the transverse direction.

On peut ainsi réaliser un mur présentant une certaine inclinaison par rapport à la verticale pour épouser et soutenir un talus de terre.It is thus possible to make a wall having a certain inclination relative to the vertical to marry and support a bank of land.

Cependant, l'emboîtement réalisé par deux crans et deux alvéoles impose un alignement parfaitement rectiligne des éléments d'une rangée et ne permet pas de réaliser un mur de soutènement présentant une certaine courbure. Aucun pivot relatif entre les éléments n'est possible par absence de jeu.However, the interlocking made by two notches and two cells imposes a perfectly straight alignment of the elements of a row and does not allow to make a retaining wall having a certain curvature. No relative pivot between the elements is possible by lack of play.

Le but de la présente invention est de créer des éléments de construction du genre précité qui permettent de réaliser un mur de soutènement pouvant présenter une certaine courbure, tout en étant suffisamment calés les uns par rapport aux autres pour assurer la stabilité du mur.The object of the present invention is to create construction elements of the aforementioned kind which make it possible to make a retaining wall that can have a certain curvature, while being sufficiently wedged relative to each other to ensure the stability of the wall.

Suivant l'invention, l'élément de construction destiné à coopérer en superposition avec au moins un élément de construction similaire, chacun des éléments comportant une face de dessus, une face de dessous, une face avant et une face arrière et au moins deux alvéoles de section allongée débouchant sur la face de dessus et sur la face de dessous, ces deux alvéoles étant alignées sensiblement parallèlement à la face arrière, est caractérisé en ce que ledit élément de construction comporte, sur sa face de dessous et dans une zone centrale de celle-ci, une partie en saillie pouvant s'engager avec jeu dans l'une desdites alvéoles de section allongée.According to the invention, the construction element intended to cooperate in superposition with at least one similar element of construction, each of the elements comprising a top face, a bottom face, a front face and a rear face and at least two cells of elongate section opening on the top face and on the bottom face, these two cells being aligned substantially parallel to the rear face, is characterized in that said construction element comprises, on its underside and in a central zone thereof, a protruding portion engageable with play in one of said recesses of elongate section.

L'emboîtement avec jeu de ladite partie en saillie de l'un des éléments dans une alvéole de l'autre élément permet une rotation relative qui permet de placer côte à côte deux éléments formant entre eux un certain angle et ainsi de réaliser un mur de soutènement présentant une certaine courbure.The interlocking play of said projecting portion of one of the elements in a cell of the other element allows a relative rotation which makes it possible to place side by side two elements forming between them a certain angle and thus to make a wall of supporting with a certain curvature.

De plus, étant donné que la partie en saillie est située dans une zone centrale et que les alvéoles sont situées près de la face arrière de l'élément, lorsque les deux éléments sont superposés, ceux-ci sont décalés dans une direction perpendiculaire à leur longueur.In addition, since the projecting portion is located in a central zone and the cells are located near the rear face of the element, when the two elements are superimposed, they are offset in a direction perpendicular to their axis. length.

On peut ainsi réaliser, après superposition de plusieurs rangées d'éléments, un mur qui, non seulement présente une certaine courbure, mais présente également l'inclinaison souhaitée.It is thus possible, after superposition of several rows of elements, a wall which not only has a certain curvature, but also has the desired inclination.

Selon une version préférée de l'invention, la face de dessous dudit élément comprend une première nervure en saillie qui s'étend parallèlement à la face arrière de l'élément le long du bord intérieur de l'une des alvéoles allongées.According to a preferred version of the invention, the underside of said element comprises a first projecting rib which extends parallel to the rear face of the element along the inner edge of one of the elongated cells.

De préférence également, la face de dessous dudit élément comprend une seconde nervure en saillie qui s'étend dans le prolongement d'une partie de la face arrière de l'élément.Also preferably, the underside of said element comprises a second projecting rib which extends in the extension of a portion of the rear face of the element.

Ainsi, lorsque deux éléments similaires sont superposés, la partie en saillie de la face de dessous de l'élément supérieur est engagée avec jeu dans l'une des alvéoles allongées de l'élément inférieur et la première nervure de l'élément supérieur s'étend le long du bord supérieur de la face arrière de l'élément inférieur, en recouvrant une partie de la longueur dudit bord.Thus, when two similar elements are superimposed, the projecting portion of the bottom face of the upper element is engaged playfully in one of the elongated cells of the lower element and the first rib of the upper element s' extends along the upper edge of the rear face of the lower member, covering a portion of the length of said edge.

La nervure ci-dessus forme ainsi une butée pour le bord correspondant de l'élément inférieur, contribuant au calage des deux éléments dans la direction transversale.The rib above and forms a stop for the corresponding edge of the lower element, contributing to the wedging of the two elements in the transverse direction.

De préférence également, le jeu compris entre ladite partie en saillie et les faces longitudinales de ladite alvéole est tel qu'il permet une certaine rotation entre ces deux éléments, qui est limitée par la butée formée entre ladite première nervure et ledit bord supérieur.Also preferably, the clearance between said projecting portion and the longitudinal faces of said cell is such that it allows a certain rotation between these two elements, which is limited by the stop formed between said first rib and said upper edge.

Suivant d'autres possibilités :

  • un côté raccordant la face arrière à la face avant présente une zone en retrait à proximité de la face arrière
  • l'autre côté raccordant la face arrière à la face avant présente une zone complémentaire à proximité de la face arrière de sorte que la zone de retrait et la zone complémentaire d'éléments juxtaposés s'imbriquent
  • la zone en retrait et la zone complémentaire sont formées par des angles droits dont un côté est parallèle à la face arrière pour réaliser des virages à angle droit.
Next to other possibilities:
  • a side connecting the rear face to the front face has a recessed area near the rear face
  • the other side connecting the rear face to the front face has a complementary zone near the rear face so that the withdrawal zone and the complementary zone of juxtaposed elements interlock
  • the recessed area and the complementary area are formed by right angles one side of which is parallel to the rear face for making right angle turns.

Les figures annexées représentent des éléments de construction destinés à coopérer en superposition chacun avec au moins un élément de construction similaire.The appended figures represent construction elements intended to cooperate in superposition each with at least one similar element of construction.

Chacun des éléments comporte une face de dessus 1, une face de dessous 2, une face avant 3 et une face arrière 4 et des alvéoles dont deux alvéoles 5, 6 de section allongée débouchant sur la face de dessus 1 et sur la face de dessous 2. Ces deux alvéoles allongées 5, 6 sont alignées sensiblement parallèlement à la face arrière 4.Each of the elements comprises a top face 1, a bottom face 2, a front face 3 and a rear face 4 and cells whose two recesses 5, 6 of elongate section opening on the top face 1 and on the underside 2. These two elongated cells 5, 6 are aligned substantially parallel to the rear face 4.

Conformément à l'invention, chaque élément de construction comporte (voir figures 2 et 3), sur sa face de dessous 2 et dans une zone centrale de celle-ci, une partie en saillie 7, par exemple de section rectangulaire, pouvant s'engager avec jeu dans l'une desdites alvéoles 5, 6 de section allongée, comme montré par la figure 5.According to the invention, each construction element comprises (see Figures 2 and 3 ), on its underside 2 and in a central region thereof, a protruding portion 7, for example of rectangular section, engageable with play in one of said recesses 5, 6 of elongated section, as shown by the figure 5 .

Les figures 3 et 4 montrent en outre que la face de dessous 2 d'un élément de construction comprend une première nervure 8 en saillie qui s'étend parallèlement à la face arrière 4 de l'élément le long du bord longitudinal intérieur 5a de l'une 5 des alvéoles allongées.The Figures 3 and 4 further show that the underside 2 of an element of The construction comprises a first protruding rib 8 which extends parallel to the rear face 4 of the element along the inner longitudinal edge 5a of one of the elongate cells.

La face de dessous 2 de l'élément comprend en outre une seconde nervure 9 en saillie qui s'étend dans le prolongement d'une partie de la face arrière 4 de l'élément.The underside 2 of the element further comprises a second projecting rib 9 which extends in the extension of a portion of the rear face 4 of the element.

Chacune des nervures 8, 9 s'étend à partir de l'une des extrémités de l'élément jusqu'à un point situé au-delà du milieu de l'élément.Each of the ribs 8, 9 extends from one end of the element to a point beyond the middle of the element.

La hauteur des nervures 8, 9 est égale à la hauteur de la partie en saillie 7, de sorte que lorsque la face de dessous 2 repose sur un sol plan, les nervures 8, 9 et la partie en saillie 7 prennent simultanément appui sur ce sol en assurant sa stabilité et son ancrage au sol lorsque celui-ci est meuble.The height of the ribs 8, 9 is equal to the height of the projecting portion 7, so that when the bottom face 2 rests on a plane ground, the ribs 8, 9 and the projecting portion 7 simultaneously bear on this ground, ensuring its stability and anchoring to the ground when it is loose.

Sur la figure 5, les nervures 8, 9 et la partie en saillie 7 sont représentées hachurées pour montrer qu'elles sont en saillie.On the figure 5 , the ribs 8, 9 and the projecting portion 7 are shown hatched to show that they are projecting.

Comme montré par la figure 5, lorsque deux éléments similaires A, B sont superposés, la partie en saillie 7 de la face de dessous 2 de l'élément supérieur A est engagée avec jeu dans l'une 6 des alvéoles allongées de l'élément inférieur B et la première nervure de l'élément supérieur A s'étend le long du bord supérieur de la face arrière 4 de l'élément inférieur B, en recouvrant une partie de la longueur de ce bord.As shown by figure 5 when two similar elements A, B are superimposed, the protruding part 7 of the bottom face 2 of the upper element A is engaged with play in one of the elongated cells of the lower element B and the first rib of the upper member A extends along the upper edge of the rear face 4 of the lower member B, covering a portion of the length of this edge.

Le jeu compris entre la partie en saillie 7 et les faces longitudinales 6a, 6b de l'alvéole 6 est tel qu'il permet une certaine rotation entre les deux éléments A, B.The clearance between the projecting portion 7 and the longitudinal faces 6a, 6b of the cell 6 is such that it allows a certain rotation between the two elements A, B.

Cette rotation est limitée par la butée formée entre ladite première nervure 8 de l'élément 4 et le bord supérieur de la face arrière 4 de l'élément B.This rotation is limited by the stop formed between said first rib 8 of the element 4 and the upper edge of the rear face 4 of the element B.

Les lignes pointillées L1 et L2 représentées sur la figure 5 symbolisent les positions angulaires extrêmes que peut prendre l'élément B par rapport à l'élément A.The dotted lines L 1 and L 2 represented on the figure 5 symbolize the extreme angular positions that element B can take with respect to element A.

Les figures 3 à 5 montrent d'autre part que la partie en saillie 7 est formée sur la face de dessous d'une paroi 10 séparant deux grandes alvéoles 11, 12 distinctes des deux alvéoles allongées 5, 6.The Figures 3 to 5 show on the other hand that the projecting portion 7 is formed on the underside of a wall 10 separating two large cells 11, 12 distinct from the two elongated cells 5, 6.

Par ailleurs, les figures 1 et 5 montrent que la face arrière 4 de chaque élément est raccordée à la face avant 3, de chaque côté, par une face 13, 14 de section circulaire qui est convexe d'un côté et concave de l'autre, de façon à pouvoir s'emboîter avec une face complémentaire d'un élément voisin, comme indiqué sur la figure 5.Moreover, figures 1 and 5 show that the rear face 4 of each element is connected to the front face 3, on each side, by a face 13, 14 of circular section which is convex on one side and concave on the other, so as to be able to fit with a complementary face of a neighboring element, as indicated on the figure 5 .

Le rayon de ces faces 13, 14 de section circulaire est tel qu'il permet de disposer deux éléments voisins suivant un certain angle pour réaliser un mur de soutènement présentant une certaine courbure.The radius of these faces 13, 14 of circular section is such that it allows to have two adjacent elements at a certain angle to make a retaining wall having a certain curvature.

Les figures 1 et 5 montrent une partie de mur de soutènement dans lequel les rangées sont décalées l'une par rapport à l'autre d'une longueur qui est réglable selon la longueur de l'alvéole 6 dans laquelle est engagée la partie en saillie 7.The figures 1 and 5 show a part of retaining wall in which the rows are offset relative to each other by a length which is adjustable along the length of the cell 6 in which is engaged the projecting portion 7.

Cependant, en règle générale, le décalage est d'une demi-longueur d'élément.However, as a rule, the offset is half a length of element.

Pour tenir compte de ce décalage, le mur de soutènement peut comporter, aux extrémités de certaines rangées, des demi-éléments dont la structure correspond sensiblement à la découpe d'un élément standard tel que représenté sur les figures 2 et 3 suivant un plan perpendiculaire à la longueur d'un élément et passant par le milieu d'une partie en saillie 7. De tels demi-éléments sont représentés sur les figures 6 à 11.To take account of this offset, the retaining wall may comprise, at the ends of certain rows, half-elements whose structure corresponds substantially to the cutout of a standard element as shown in FIGS. Figures 2 and 3 in a plane perpendicular to the length of an element and passing through the middle of a projecting portion 7. Such half-elements are represented on the Figures 6 to 11 .

Ces éléments ne comportent que deux alvéoles 6, 12 et la saillie 7a a une longueur égale à la moitié de celle de l'élément standard.These elements comprise only two cells 6, 12 and the projection 7a has a length equal to half that of the standard element.

Les nervures 9a et 8a sont également présentes mais leur longueur est plus réduite.The ribs 9a and 8a are also present but their length is shorter.

Le demi-élément représenté sur les figures 6, 7 et 8 est un demi-élément de gauche, adapté pour être placé à l'extrémité d'une rangée de gauche.The half-element represented on the Figures 6, 7 and 8 is a half-left element, adapted to be placed at the end of a left row.

Le demi-élément représenté sur les figures 9, 10 et 11 est un demi-élément de droite, adapté pour être placé à l'extrémité d'une rangée de droite.The half-element represented on the Figures 9, 10 and 11 is a half-line element, adapted to be placed at the end of a right-hand row.

La saillie 7a et les nervures 8a et 9a des demi-éléments ci-dessus présentent les mêmes fonctions que la saillie 7 et les nervures 8 et 9 des éléments standards représentés sur les figures 1 à 5. Ces demi-éléments évitent d'avoir à couper en deux un élément standard.The projection 7a and the ribs 8a and 9a of the half-elements above have the same functions as the projection 7 and the ribs 8 and 9 of the standard elements represented on the Figures 1 to 5 . These half-elements avoid having to cut in half a standard element.

L'élément de construction que l'on vient de décrire présente tous les avantages de celui décrit dans la demande de brevet FR 2 845 404 et offre en plus la possibilité de réaliser des murs de soutènement courbes.The construction element that has just been described has all the advantages of that described in the patent application. FR 2,845,404 and offers in addition the possibility of making curved retaining walls.

Suivant une possibilité additionnelle, l'élément de l'invention permet des virages à angle droit tels ceux illustrés aux figures 12 et 13.According to an additional possibility, the element of the invention allows right-angle turns such as those illustrated in FIGS. figures 12 and 13 .

A cet effet, les éléments comportent avantageusement en complément des faces convexes et concaves 13, 14, une zone en retrait 15 et une zone complémentaire 16 sur leurs côtés 17, 18. Ces zones 15, 16 sont situées à proximité de la face arrière 4 si bien qu'elles permettent la formation d'angles entre éléments à ce niveau.For this purpose, the elements advantageously comprise, in addition to convex and concave faces 13, 14, a recessed zone 15 and a complementary zone 16 on their sides 17, 18. These zones 15, 16 are located near the rear face 4 so that they allow the formation of angles between elements at this level.

Comme illustré, les zones 15, 16 sont avantageusement en angles droits relativement à la face arrière 4 pour former, en coopération de deux éléments juxtaposés, un virage à 90°. La nature de cette imbrication offre en outre une résistance élevée et un blocage vertical parfait, sans vide entre éléments.As illustrated, the zones 15, 16 are advantageously at right angles to the rear face 4 to form, in cooperation with two juxtaposed elements, a 90 ° turn. The nature of this nesting also offers high strength and a perfect vertical lock, without void between elements.
