Description

La présente invention a trait à la réalisation de caveaux funéraires à partir d'éléments modulaires de construction fabriqués hors du chantier pour être assemblés sur place. Elle concerne plus particulièrement un dispositif de coffrage de ces éléments de construction.The present invention relates to the production of burial vaults from modular construction elements manufactured outside the site to be assembled on site. It relates more particularly to a formwork device for these construction elements.

Le mode classique de construction d'un caveau funéraire in situ, dont nous ne rappellerons pas les nombreux inconvénients de coût et de fiabilité, a été abandonné ces dernières années au profit des caveaux funéraires préfabriqués à partir d'éléments produits hors du chantier et assemblés sur place. Ce nouveau mode de construction offre de nombreux avantages et notamment :

  • - un prix de revient réduit car la fabrication de ces éléments est particulièrement indiquée pour une production en série ;
  • - une rapidité accrue d'installation du caveau préfabriqué dans la fosse funéraire appropriée, grâce à la diminution de main d'oeuvre exigée sur le chantier qui se limite maintenant aux travaux d'assemblage et de jonction des éléments entre eux.
The classic method of building a funeral vault in situ, the many drawbacks of cost and reliability of which we will not recall, has been abandoned in recent years in favor of prefabricated funeral vaults from elements produced outside the site and assembled on the spot. This new construction method offers many advantages, in particular:
  • - a reduced cost price because the manufacture of these elements is particularly suitable for mass production;
  • - an increased speed of installation of the prefabricated vault in the appropriate funeral grave, thanks to the reduction in labor required on the site which is now limited to the assembly and joining of the elements between them.

Selon ce mode de construction, les brevets français n°2.362.261 et n°2.426.786 décrivent des caveaux funéraires préfabriqués à partir de cadres horizontaux interposés entre les jeux de panneaux de cases superposées et dont les côtés sont pourvus de conformations d'assemblage assurant la jonction et le maintien par emboîtement des panneaux latéraux.According to this method of construction, French patents No. 2,362,261 and No. 2,426,786 describe prefabricated burial vaults from horizontal frames interposed between the sets of panels of stacked boxes and whose sides are provided with assembly conformations ensuring the junction and the interlocking of the side panels.

Toutefois, la production de ces panneaux procède encore des techniques classiques de coffrage, ce qui constitue un obstacle à la généralisation de ce mode de construction, en raison notamment des coûts générés par ces techniques.However, the production of these panels still proceeds from conventional formwork techniques, which constitutes an obstacle to the generalization of this method of construction, in particular because of the costs generated by these techniques.

La demanderesse a ainsi imaginé un dispositif pour la production d'éléments modulaires monoblocs lesquels, bien que destinés plus particulièrement à la réalisation de caveaux funéraires, peuvent également être utilisés pour la construction de réservoirs, grâce à la bonne étanchéité assurée à l'ensemble de la réalisation. Ces constructions sont obtenues notamment par la superposition des éléments modulaires qui, adoptant la forme de parallélépipèdes ouverts à l'un au moins de leurs plans de base, sont remarquables en ce que la paroi latérale desdits éléments, dessinée par les quatre faces fermées du parallélépipède, est plus épaisse à sa partie haute qu'à sa partie basse.The Applicant has thus imagined a device for the production of one-piece modular elements which, although intended more particularly for the production of burial vaults, can also be used for the construction of reservoirs, thanks to the good sealing provided to the assembly of the achievement. These constructions are obtained in particular by the superposition of modular elements which, adopting the form of parallelepipeds open to at least one of their base planes, are remarkable in that the side wall of said elements, drawn by the four closed faces of the parallelepiped, is thicker at its top than at its bottom.

Afin de mieux comprendre l'invention, nous donnons ci-après quelques définitions des différentes parties constitutives de la paroi latérale du parallélépipède. Ainsi :

  • - les faces sont les quatre parties solides de la paroi et sont délimitées par les quatre côtés du parallélépipède,
  • - les surfaces sont les côtés les plus larges des faces et sont situées à l'intérieur ou à l'extérieur du parallélépipède,
  • - les chants sont les côtés les plus étroits des faces, entre les surfaces intérieure et extérieure, et sont situés en haut (chant supérieur) et en bas (chant inférieur) de la paroi latérale.
In order to better understand the invention, we give below some definitions of the various constituent parts of the side wall of the parallelepiped. So :
  • - the faces are the four solid parts of the wall and are delimited by the four sides of the parallelepiped,
  • - the surfaces are the widest sides of the faces and are located inside or outside the parallelepiped,
  • - the edges are the narrowest sides of the faces, between the interior and exterior surfaces, and are located at the top (top edge) and bottom (bottom edge) of the side wall.

La paroi latérale du parallélépipède est donc constituée de quatre faces délimitées chacune par deux surfaces intérieure et extérieure et deux chants inférieur et supérieur.The side wall of the parallelepiped therefore consists of four faces each delimited by two interior and exterior surfaces and two lower and upper edges.

Les deux plans de base, généralement ouverts, sont, quant à eux, délimités par les deux chants inférieur et supérieur de la paroi latérale.The two generally open base planes are delimited by the two upper and lower edges of the side wall.

Ces différences d'épaisseur entre le haut et le bas de la paroi latérale de l'élément modulaire de construction, objet de la présente invention, définissent ainsi une largeur plus importante pour le chant supérieur que pour le chant inférieur, Il en résulte que le chant supérieur comporte une largeur située vers l'extérieur et servant d'assise au chant inférieur de l'élément modulaire superposé, et une largeur située vers l'intérieur et délimitant un rebord périphérique interne sur lequel peut être déposée une cloison horizontale de séparation.These thickness differences between the top and the bottom of the side wall of the modular building element, object of the present invention, thus define a greater width for the upper edge than for the lower edge. It follows that the upper edge has a width located towards the outside and serving as a seat for the lower edge of the superimposed modular element, and a width located towards the inside and delimiting an internal peripheral rim on which a horizontal partition can be deposited.

L'invention a ainsi pour objet un dispositif pour la préfabrication en série de tels éléments modulaires de construction. A cet effet, ce dispositif est constitué :

  • - d'un châssis sur lequel est fixé un panneau horizontal rectangulaire,
  • - de quatre panneaux verticaux articulés sur les quatre côtés du panneau horizontal,
  • - de moyens pour mouvoir lesdits panneaux verticaux,
  • - d'une matrice adoptant la forme d'une pyramide à section rectangulaire et tronquée selon un plan parallèle au plan de base inférieur, ladite matrice étant portée par le panneau horizontal et entourée par les quatre panneaux verticaux articulés,
  • - et enfin, de moyens pour permettre la rotation sur lui-même de ce dispositif.
The invention thus relates to a device for the prefabrication in series of such modular building elements. To this end, this device consists of:
  • - a frame on which is fixed a rectangular horizontal panel,
  • - four vertical panels hinged on the four sides of the horizontal panel,
  • - means for moving said vertical panels,
  • a matrix adopting the shape of a pyramid with rectangular section and truncated along a plane parallel to the lower base plane, said matrix being carried by the horizontal panel and surrounded by the four articulated vertical panels,
  • - And finally, means to allow the rotation on itself of this device.

Le panneau horizontal a notamment pour rôle de supporter les autres organes du dispositif. La matrice pyramidale est dessinée de manière à donner l'empreinte des surfaces intérieures de la paroi latérale du parallélépipède, et les panneaux verticaux, qui donnent l'empreinte des surfaces extérieures de ladite paroi, sont articulés afin d'autoriser le décoffrage du béton qui a fait prise.The role of the horizontal panel is in particular to support the other organs of the device. The pyramidal matrix is designed so as to give the imprint of the interior surfaces of the side wall of the parallelepiped, and the vertical panels, which give the imprint of the exterior surfaces of said wall, are articulated in order to allow the formwork to be removed from the concrete which has taken hold.

L'invention sera mieux comprise et ses caractéristiques et ses avantages apparaîtront plus clairement à la lecture de ce qui sera dit ci-après. L'exposé qui suit fait référence aux dessins annexés qui montrent respectivement :

  • - à la figure 1, une vue en perspective, partiellement écorchée, d'un caveau funéraire composé de deux éléments monoblocs de construction obtenus avec le dispositif de l'invention ;
  • - à la figure 2, une vue en perspective, partiellement écorchée, du dispositif permettant de produire les éléments de la figure 1.
The invention will be better understood and its characteristics and advantages will appear more clearly on reading what will be said below. The following description refers to the accompanying drawings which show respectively:
  • - In Figure 1, a perspective view, partially broken away, of a funeral vault composed of two monoblock construction elements obtained with the device of the invention;
  • - in Figure 2, a perspective view, partially broken away, of the device for producing the elements of Figure 1.

Il a en effet été jugé préférable, pour une meilleure exposition de l'invention, de décrire en premier lieu un exemple de réalisation d'un caveau funéraire avec des éléments obtenus en mettant en oeuvre le dispositif de coffrage de l'invention avant de s'attacher à ce dernier.It was indeed considered preferable, for a better exposure of the invention, to first describe an example of an embodiment of a funerary vault with elements obtained by implementing the formwork device of the invention before s 'attach to the latter.

Le caveau représenté sur le dessin de la figure 1, destiné à être enseveli dans une fosse funéraire où il sera recouvert d'une pierre tombale, comporte deux éléments modulaires de construction I et II constituant : le premier, le fond du caveau, et le second, un étage de ce dernier sur lequel reposera la pierre tombale. Ces éléments 1 et Il adoptent chacun la forme d'un parallélépipède constitué d'une part, d'une paroi latérale 1 fermée par quatre faces et dont les contours sont délimités par deux surfaces, intérieure et extérieure, respectivement 1' et 1", et par deux chants, inférieur et supérieur, respectivement 1a et 1b, et, d'autre part, de deux plans de base, bas 2a et haut 2b, circonscrits respectivement par les contours intérieurs des deux chants 1a et 1b. Dans l'élément I, constituant le fond du caveau, le plan de base bas 2a est fermé et le plan de base haut 2b est ouvert alors que dans l'élément Il, les deux plans de base sont ouverts.The vault represented on the drawing of figure 1, intended to be buried in a funeral grave where it will be covered with a tombstone, comprises two modular elements of construction I and II constituting: the first, the bottom of the vault, and the second, a floor of the latter on which the tombstone will rest. These elements 1 and II each take the form of a parallelepiped consisting on the one hand, of a side wall 1 closed by four faces and the contours of which are delimited by two surfaces, interior and exterior, respectively 1 ′ and 1 ", and by two edges, lower and upper, respectively 1a and 1b, and, on the other hand, of two basic planes, bottom 2a and top 2b, circumscribed respectively by the interior contours of the two edges 1a and 1b. I, constituting the bottom of the vault, the bottom base plane 2a is closed and the top base plane 2b is open while in element II, the two base planes are open.

On observera que la surface extérieure 1" de la paroi 1 de l'élément modulaire II est perpendiculaire aux plans de base et que la surface intérieure 1' est inclinée et forme un angle aigu avec le plan de base inférieur 2a. Il s'ensuit que le chant supérieur 1b est plus large que le chant inférieur 1a. Ce dernier peut ainsi reposer aisément sur le chant supérieur 1b de l'élément sous-jacent (l'élément I), tout en dégageant sur le chant 1b un rebord périphérique interne qui est surmonté d'un épaulement 1'b. Ce dernier définit un support périphérique interne sur lequel peut reposer une cloison horizontale de séparation et donne également la possibilité de parachever l'étanchéité du scellement assurant la jonction entre le chant supérieur 1b de l'élément 1 et le chant inférieur 1a de l'élément 11. Il est utile de préciser que, lorsque le caveau funéraire préfabriqué possède plusieurs étages, la disposition perpendiculaire aux plans de base 2a et 2b des surfaces extérieures 1" des éléments Il autorise une superposition de ces derniers qui sont façonnés de manière identique et sont assemblés l'un sur l'autre selon le même mode que celui décrit ci-dessus. Cette disposition donne également un aspect extérieur régulier au caveau, notamment sur sa hauteur surmontant celle de l'élément de fond 1.It will be observed that the outer surface 1 "of the wall 1 of the modular element II is perpendicular to the base planes and that the inner surface 1 'is inclined and forms an acute angle with the lower base plane 2a. It follows that the upper edge 1b is wider than the lower edge 1a. The latter can thus easily rest on the upper edge 1b of the underlying element (element I), while releasing on the edge 1b an internal peripheral rim which is surmounted by a shoulder 1'b. This defines an internal peripheral support on which a horizontal partition can rest and also gives the possibility of complete the sealing of the seal ensuring the junction between the upper edge 1b of the element 1 and the lower edge 1a of the element 11. It is useful to specify that, when the prefabricated funeral vault has several floors, the arrangement perpendicular to the basic planes 2a and 2b of the external surfaces 1 "of the elements It allows a superposition of the latter which are shaped identically and are assembled one on the other according to the same mode as that described above. This arrangement gives also a regular external appearance to the cellar, in particular on its height surmounting that of the bottom element 1.

Le dispositif, illustré à la figure 2 et référencé 10 dans son ensemble, permet de produire en une seule opération des éléments du genre de ceux qui viennent d'être décrits, en maintenant, dans des volumes donnant l'empreinte desdits éléments, la masse de béton jusqu'à sa prise complète.The device, illustrated in FIG. 2 and referenced 10 as a whole, makes it possible to produce, in a single operation, elements of the kind of those which have just been described, while maintaining, in volumes giving the imprint of said elements, the mass concrete until completely set.

Suivant l'invention, ce dispositif 10, communément appelé dispositif de coffrage, comprend un châssis support formé de quatre longerons 11 en 1 disposés deux à deux parallèles entre eux et de part et d'autre des plans médians dudit dispositif. Sur ce châssis est fixé un panneau horizontal 12, de forme rectangulaire, sur les arêtes duquel sont montés articulés (flèche à double sens A) quatre panneaux verticaux 13a, 13b, 13c et 13d.According to the invention, this device 10, commonly known as a shuttering device, comprises a support frame formed by four longitudinal members 11 in 1 arranged two by two parallel to each other and on either side of the median planes of said device. On this chassis is fixed a horizontal panel 12, of rectangular shape, on the edges of which are articulated (two-way arrow A) four vertical panels 13a, 13b, 13c and 13d.

L'expansion angulaire (flèche A) de ces panneaux articulés 13a, 13b, 13c, 13d, est assurée pour chacun de ces derniers par deux vérins 15a, 16a... 15d, 16d respectivement, qui sont, d'une part, calés entre les extrémités des longerons du châssis support et les surfaces extérieures desdits panneaux et, d'autre part, reliés à une centrale de commande manuelle non représentée.The angular expansion (arrow A) of these articulated panels 13a, 13b, 13c, 13d, is ensured for each of these by two jacks 15a, 16a ... 15d, 16d respectively, which are, on the one hand, wedged between the ends of the longitudinal members of the support frame and the exterior surfaces of said panels and, on the other hand, connected to a manual control unit not shown.

Selon une caractéristique préférée de réalisation de l'invention destinée à corriger les jeux d'articulation, ces vérins 15, 16 ont leur corps monté pivotant (flèches à double sens P) sur un jambage dressé sur les extrémités des longerons 11 et leur tête montée articulée (flèches à double sens V) sur la hauteur des panneaux 13.According to a preferred characteristic of embodiment of the invention intended to correct the articulation games, these jacks 15, 16 have their body pivotally mounted (two-way arrows P) on a leg erected on the ends of the side members 11 and their head mounted articulated (two-way arrows V) on the height of the panels 13.

Au centre du panneau 12 et entourée par les panneaux verticaux 13a à 13 d, est installée une matrice 14 adoptant la forme d'une pyramide à base rectangulaire, tronquée selon un pian parallèle au plan de base. La matrice 14 a pour rôle de donner l'empreinte des surfaces intérieures des parois latérales 1 des éléments I et II, et les panneaux articulés 13a à 13d celui de donner l'empreinte des surfaces extérieures 1".At the center of the panel 12 and surrounded by the vertical panels 13a to 13 d, is installed a matrix 14 adopting the shape of a pyramid with rectangular base, truncated according to a plane parallel to the base plane. The role of the matrix 14 is to give the imprint of the interior surfaces of the side walls 1 of elements I and II, and the articulated panels 13a to 13d that of giving the imprint of the exterior surfaces 1 ".

Pour l'opération de coffrage d'un élément modulaire d'étage II par le dispositif 10, et sous l'effet des développements des têtes de vérins 15, 16, les panneaux 13a, 13b, 13c, 13d sont dressés perpendiculairement entre eux et au plan du panneau horizontal 12 et sont consolidés dans cette position par des systèmes de clavetage 17. Pour l'opération de décoffrage, il suffit de déclaveter les panneaux et de faire rétracter les têtes des vérins 15, 16 pour que les panneaux 13a à 13d s'écartent vers l'extérieur, dégageant ainsi les surfaces extérieures 1" de la paroi 1. A l'aide d'un appareil de levage classique, l'élément 11 est soulevé par son chant supérieur 1b muni à cet effet d'anneaux de préhension (non représentés sur le dessin de la figure 1 et qui seront noyés dans la masse de scellement lors de l'assemblage), de sorte que cet élément est dégagé de la matrice 14 et du panneau horizontal 12, décoffrant ainsi les surfaces intérieures 1' et le chant inférieur 1a de la paroi 1.For the shuttering operation of a modular stage element II by the device 10, and under the effect of the developments of the heads of jacks 15, 16, the panels 13a, 13b, 13c, 13d are erected perpendicularly to each other and to the plane of the horizontal panel 12 and are consolidated in this position by keying systems 17. For the formwork removal operation, it is sufficient to unclip the panels and to retract the heads of the jacks 15, 16 so that the panels 13a to 13d move outward, thereby freeing up the surfaces external 1 "of the wall 1. Using a conventional lifting device, the element 11 is lifted by its upper edge 1b provided for this purpose with gripping rings (not shown in the drawing of FIG. 1 and which will be embedded in the sealing mass during assembly), so that this element is released from the matrix 14 and from the horizontal panel 12, thus removing the interior surfaces 1 ′ and the lower edge 1a of the wall 1.

Pour l'opération de coffrage d'un élément modulaire de fond I, par le dispositif 10, les panneaux 13a, 13b, 13c, 13d sont dressés quant à eux selon des plans sensiblement parallèles aux plans trapézoïdaux de la matrice 14 et sont également consolidés dans cette position par les systèmes de clavetage 17. Il est utile cependant d'ajouter que, dans cette opération, le plan de base supérieur de la matrice pyramidale 14 est recouvert d'une épaisseur de béton égale à la hauteur séparant la partie supérieure des panneaux 13a à 13d du plan de base de la matrice. Cette épaisseur de béton constitue ainsi le fond (plan de base inférieur fermé 2a) de l'élément 1.For the formwork operation of a modular bottom element I, by the device 10, the panels 13a, 13b, 13c, 13d are erected in turn according to planes substantially parallel to the trapezoidal planes of the matrix 14 and are also consolidated in this position by the keying systems 17. It is useful however to add that, in this operation, the upper base plane of the pyramidal matrix 14 is covered with a thickness of concrete equal to the height separating the upper part of the panels 13a to 13d of the base plane of the matrix. This thickness of concrete thus constitutes the bottom (closed lower base plane 2a) of the element 1.

Pour l'opération de décoffrage, l'ensemble du dispositif 10 est soulevé par un appareil de levage, ceci grâce à un support 18 en forme d'étrier équipé d'un crochet de préhension 18a, étrier dont les deux branches supportent un axe 19 disposé dans le plan médian longitudinal du dispositif et autour duquel le susdit châssis est monté en libre rotation (flèches à double sens R). Une fois soulevé, le dispositif retenant l'élément 1, ayant fait prise, pivote d'un demi-tour autour de son axe 19 et est reposé sur le sol. Les panneaux 13 sont alors écartés par l'action des vérins 15, 16, décoffrant ainsi les surfaces extérieures 1" de la paroi 1. L'ensemble du dispositif 10 est à nouveau soulevé pour dégager la matrice 14 et le panneau 12, décoffrant ainsi les surfaces intérieures 1' et le plan de base fermé 2a de l'élément 1. Ce dernier pourra ensuite être transposé à un autre endroit en le soulevant par son chant supérieur 1b qui sera équipé des mêmes anneaux de préhension que celui de l'élément Il.For the formwork removal operation, the entire device 10 is lifted by a lifting device, this thanks to a support 18 in the form of a stirrup equipped with a gripping hook 18a, stirrup of which the two branches support an axis 19 disposed in the longitudinal median plane of the device and around which the aforesaid chassis is mounted in free rotation (two-way arrows R). Once raised, the device retaining the element 1, having taken hold, pivots by a half-turn around its axis 19 and is rested on the ground. The panels 13 are then separated by the action of the jacks 15, 16, thus removing the external surfaces 1 "from the wall 1. The whole of the device 10 is again lifted to release the matrix 14 and the panel 12, thus removing the the interior surfaces 1 'and the closed base plane 2a of the element 1. The latter can then be transposed to another place by lifting it by its upper edge 1b which will be equipped with the same gripping rings as that of the element He.

L'épaulement périphérique 1'b garnissant le chant supérieur 1b des deux éléments monoblocs I et Il est obtenu à l'aide d'une empreinte amovible non représentée et adoptant la forme d'un cadre rectangulaire muni de poignées. Cette empreinte est solidaire du panneau horizontal 12 et du plan de base inférieur de la matrice pyramidale 14 pour l'élément de fond I alors qu'elle est déposée sur la masse de béton coulée et autour du plan de base supérieur de la matrice 14 pour l'élément Il. Les dimensions du cadre de cette empreinte sont telles que son épaisseur est égale à la hauteur de l'épaulement 1'b et sa largeur égale à celle du chant supérieur 1b laissée libre par le susdit épaulement.The peripheral shoulder 1'b lining the upper edge 1b of the two monoblock elements I and It is obtained using a removable imprint not shown and adopting the shape of a rectangular frame provided with handles. This imprint is integral with the horizontal panel 12 and the lower base plane of the pyramidal matrix 14 for the bottom element I while it is deposited on the mass of poured concrete and around the upper base plane of the matrix 14 for the element It. The dimensions of the frame this imprint are such that its thickness is equal to the height of the shoulder 1'b and its width equal to that of the upper edge 1b left free by the above shoulder.

D'autres améliorations, perfectionnements, modifications pourront être apportés par les hommes de métier à l'exemple de réalisation ci-dessus décrit et représenté sans pour autant sortir du cadre de l'invention.Other improvements, improvements, modifications may be made by those skilled in the art to the embodiment described above and shown without departing from the scope of the invention.

Ainsi, par exemple, la partie du panneau 12 située sous la matrice pyramidale (creuse de préférence) pourra être ouverte pour autoriser un étuvage de cette dernière, ce qui aura pour conséquence immédiate d'accélérer les temps de prise du béton.Thus, for example, the part of the panel 12 located under the pyramidal matrix (preferably hollow) can be opened to allow baking of the latter, which will have the immediate consequence of accelerating the setting times of the concrete.
