Description
ELEMENT D'ASSEMBLAGE D'ANGLE POUR COFFRAGE ET COFFRAGE AINSI OBTENU ANGLE ASSEMBLING MEMBER FOR FORMWORK AND FORMWORK THUS OBTAINED
La présente invention concerne un coffrage destiné à la réalisation de réservations de portes ou fenêtres dans un mur, à obtenir par coulage de béton sur place ou préfabriqué. Un tel coffrage est dans ce cas de forme quadrangulaire et constitué de quatre panneaux formant deux montants verticaux et deux traverses horizontales .The present invention relates to a formwork for the realization of reservations of doors or windows in a wall, to be obtained by pouring concrete on site or prefabricated. Such a formwork is in this case of quadrangular shape and consists of four panels forming two vertical uprights and two horizontal crosspieces.
Bien entendu, il pourra s'agir de coffrages destinés à la réalisation de réservations de toutes autres formes, triangulaire par exemple.Of course, it may be formwork for the realization of reservations of all other forms, triangular for example.
Il pourra également s'agir de réservations pour obtenir des trémies dans un plancher.It may also be reservations to get hoppers in a floor.
De tels coffrages sont de manière connue constitués par des panneaux de dimensions correspondantes à celles de la réservation, reliés entre eux à leurs extrémités par l'intermédiaire d'éléments d'assemblage d'angle.Such forms are in known manner constituted by panels of dimensions corresponding to those of the reservation, interconnected at their ends by means of corner connecting elements.
Ce type de coffrage dit également « mannequin » en terme de métier est généralement réalisé à l'aide de planches de bois dont il faut couper les extrémités selon un premier plan donnant l'angle de raccordement selon la figure géométrique à réaliser, et selon un second plan donnant aux dits panneaux une obliquité ou fruit, par rapport au plan du mur à réaliser. Ceci a pour but de faciliter le décoffrage après séchage du béton coulé, sinon difficile du fait de son adhérence sur les planches.
On comprend les difficultés qu' il y a à couper les planches selon deux angles avec précision, sauf à investir dans des machines de coupe onéreuses, nécessitant de toutes façons une main d' œuvre compétente pour leur utilisation.This type of formwork also known as "dummy" in terms of trade is usually made using wooden boards whose ends must be cut in a first plane giving the connection angle according to the geometric figure to be made, and according to a second plan giving the said panels an obliquity or fruit, compared to the plane of the wall to achieve. This is to facilitate the stripping after drying of the cast concrete, otherwise difficult because of its adherence to the boards. We understand the difficulties of cutting boards from two angles with precision, except to invest in expensive cutting machines, requiring in any case a manpower competent for their use.
Un autre inconvénient de ces coffrages traditionnels réside dans le fait qu' ils doivent être réalisés en atelier et transportés ensuite sur le chantier. Ceci induit des frais de transport importants de part l'encombrement, mais aussi de part le poids, du fait que le matériau utilisé est le bois et que l'humidité qu'il risque d'absorber augmentera son poids et de plus provoquera la déformation du coffrage ou « mannequin » avant sa mise en place.Another disadvantage of these traditional forms is that they must be made in the workshop and then transported to the site. This entails significant transport costs due to the size, but also because of the weight, because the material used is wood and the moisture that it will absorb will increase its weight and moreover will cause the deformation formwork or "dummy" before it is put in place.
Une autre difficulté réside dans l'assemblage des panneaux entre eux par l'intermédiaire d'une pièce d'angle qui, s'il s'effectue par simple collage, n'est pas sécurisé et s'il s'effectue par tenon-mortaise est compliqué et une fois de plus onéreux.Another difficulty lies in the assembly of the panels together by means of a corner piece which, if it is done simply by gluing, is not secured and if it is made by tenon- mortise is complicated and once again expensive.
Il a déjà été proposé de résoudre une partie des problèmes précités notamment celui de la coupe des panneaux, en s' affranchissant de celle-ci par l'utilisation d'un dispositif d'angle mécanique également compliqué et onéreux nécessitant la mise en œuvre d'une pluralité de pièces à fabriquer et à assembler selon certains réglages. II a donc été recherché par la présente invention de résoudre tout à la fois les difficultés précitées, liées à la découpe des
angles, à l'assemblage des éléments entre eux, à l'utilisation du bois.It has already been proposed to solve some of the aforementioned problems including the cutting of panels, by avoiding it by the use of a mechanical angle device also complicated and expensive requiring the implementation of a plurality of parts to manufacture and assemble according to certain settings. It has therefore been sought by the present invention to solve at the same time the aforementioned difficulties related to the cutting of angles, when assembling the elements together, to the use of wood.
A cet effet, l'invention concerne un coffrage dit « mannequin » destiné à la réalisation de réservations notamment pour portes ou fenêtres dans un mur, à obtenir par coulage de béton sur place ou préfabriqué, et constitués par des panneaux de dimensions correspondantes à celles de la réservation, reliés entre eux à leurs extrémités par l'intermédiaire d'éléments d'assemblage d'angle, caractérisé en ce que chacun de ces derniers est constitué par une pièce monobloc présentant deux branches de section quadrangulaire, formant entre elles un premier angle correspondant à celui de deux panneaux adjacents à assembler et un second angle correspondant à une obliquité ou fruit à donner à ces panneaux par rapport aux plan du mur, de manière à obtenir une pente et faciliter ainsi le décoffrage ultérieur du « mannequin ». Un premier avantage procuré par l'invention réside dans le fait que les extrémités de l'élément d'angle étant perpendiculaires aux côtés longitudinaux de ses branches, la découpe des extrémités des panneaux pourra toujours être effectuée à angle droit selon un plan longitudinal et selon un plan transversal, quelque soit l'angle d'ouverture, le fruit étant donné automatiquement par l'élément d'angle lors de l'assemblage.For this purpose, the invention relates to a so-called "dummy" formwork intended for the realization of reservations, in particular for doors or windows in a wall, to be obtained by casting concrete on site or prefabricated, and constituted by panels of dimensions corresponding to those of the reservation, interconnected at their ends by means of corner joining elements, characterized in that each of these is constituted by a single piece having two branches of quadrangular section, forming between them a first angle corresponding to that of two adjacent panels to assemble and a second angle corresponding to an obliquity or fruit to give to these panels relative to the plane of the wall, so as to obtain a slope and thus facilitate the subsequent stripping of the "manikin". A first advantage provided by the invention lies in the fact that the ends of the corner element being perpendicular to the longitudinal sides of its branches, the cutting of the ends of the panels can always be performed at right angles along a longitudinal plane and according to a transverse plane, whatever the angle of opening, the fruit being automatically given by the corner element during assembly.
La présente invention concerne également les caractéristiques qui ressortiront au cours de la description qui va suivre, et qui devront être
considérées isolément ou selon toutes leurs combinaisons techniques possibles.The present invention also relates to the features which will emerge during the following description, which should be considered in isolation or in all their possible technical combinations.

La figure 4 est une vue schématique simplifiée du détail A selon la figure 2 après assemblage de deux panneaux avec un élément d'angle, figure sur laquelle est représentée fictivement " en pointillés les mêmes éléments assemblés avec un élément d'angle ne donnant pas l'obliquité ou fruit, pour une meilleure compréhension de l'invention. Le coffrage 1, dit « mannequin », globalement désigné sur la figure 1, est constitué par des panneaux 2, 3, 4, 5 de dimensions correspondantes à celles de la réservation, reliés entre eux à leurs extrémités par l'intermédiaire d'éléments d'assemblage d'angle 6, 7, 8, 9.Figure 4 is a simplified schematic view of detail A according to Figure 2 after assembly of two panels with a corner element, Figure there is shown fictitiously "dotted like elements assembled with a corner element is not giving the or obliquity or fruit, for a better understanding of the invention The formwork 1, called "manikin", generally designated in Figure 1, consists of panels 2, 3, 4, 5 of dimensions corresponding to those of the reservation interconnected at their ends by means of corner connecting elements 6, 7, 8, 9.
Selon l'invention, chacun de ces derniers est constitué par une pièce monobloc présentant deux
branches 10, 11 de section quadrangulaire, formant entre elles un premier angle αl correspondant à celui de deux panneaux adjacents 2, 3 - 3, 4 - 4, 5 - 5, 2 à assembler et un second angle α4 ou α5 correspondant à une obliquité ou fruit à donner à ces panneaux par rapport au plan du mur, de manière à obtenir une pente et faciliter ainsi le décoffrage ultérieur du « mannequin » 1.According to the invention, each of these is constituted by a one-piece piece having two branches 10, 11 of quadrangular section, forming between them a first angle α1 corresponding to that of two adjacent panels 2, 3 - 3, 4 - 4, 5 - 5, 2 to be assembled and a second angle α4 or α5 corresponding to an obliquity or fruit to give to these panels in relation to the plane of the wall, so as to obtain a slope and thus facilitate the subsequent dismantling of the "manikin" 1.
Comme le montrent bien les figures 2, 3 et 4, les branches 10, 11 de chacun des éléments d'angleAs shown in FIGS. 2, 3 and 4, the branches 10, 11 of each of the corner elements
6, 7, 8, 9 comportent deux plans droits d'extrémité6, 7, 8, 9 have two end planes
12, 13 sur lesquels sont rapportées, par l'intermédiaire de moyens de liaison, les extrémités 14, 15 de deux panneaux adjacents 2, 3 - 3, 4 - 4, 5 - 5, 2 coupés à angle droit et prenant automatiquement du fruit lors du montage sur l'élément d'angle 6, 7, 8, 9.12, 13 to which are reported, via connecting means, the ends 14, 15 of two adjacent panels 2, 3 - 3, 4 - 4, 5 - 5, 2 cut at right angles and taking automatically fruit when mounting on the corner element 6, 7, 8, 9.
Préférentiellement mais non limitativement, les moyens de liaison entre les deux plans droits d'extrémité 12, 13 de chaque élément d'angle 6, 7, 8, 9 et les extrémités à angle droit 12, 13 de deux panneaux adjacents 2, 3 - 3, 4 - 4, 5 - 5, 2 sont constitués par des zones d'emboîtement complémentaires 16, 17 - 16A - 17A réalisées de part et d'autre de chacune des extrémités 12, 13 des branches 10, 11 de chacun des éléments d'angle 6, 7, 8, 9 et des extrémités 14, 15 des panneaux correspondants 2, 3, 4, 5.Preferably, but not exclusively, the connection means between the two right end planes 12, 13 of each corner element 6, 7, 8, 9 and the right-angle ends 12, 13 of two adjacent panels 2, 3 - 3, 4 - 4, 5 - 5, 2 are constituted by complementary interlocking zones 16, 17 - 16A - 17A formed on either side of each of the ends 12, 13 of the branches 10, 11 of each of the elements 6, 7, 8, 9 and the ends 14, 15 of the corresponding panels 2, 3, 4, 5.
Comme particulièrement bien visible sur les figures 2 et 3, les zones d'emboîtement 16, 17 -As particularly clearly visible in FIGS. 2 and 3, the interlocking zones 16, 17 -
16A, 17A sont du type mâle-femelle et constituées d'une part par des plots cubiques,
parallélépipédiques ou cylindriques, réalisés aux extrémités 12, 13 des branches 10, 11 des éléments d'angle 6, 7, 8, 9, et d'autre part par des logements correspondants en forme et en nombre, réalisés aux extrémités 14, 15 des panneaux 2, 3, 4, 5 à assembler.16A, 17A are of the male-female type and formed on the one hand by cubic studs, parallelepipedic or cylindrical, made at the ends 12, 13 of the branches 10, 11 of the corner elements 6, 7, 8, 9, and secondly by corresponding housings in shape and in number, made at the ends 14, 15 of the panels 2, 3, 4, 5 to be assembled.
Bien entendu, les zones d'emboîtement pourraient être renforcées par collage ou soudage, mais il sera préféré l'emboîtement libre de manière à permettre le démontage et la récupération des éléments, de manière à les rendre réutilisables ultérieurement .Of course, the interlocking zones could be reinforced by gluing or welding, but it will be preferred the free interlocking so as to allow the dismantling and recovery of the elements, so as to make them reusable later.
Préférentiellement, les logements constituant les zones d'emboîtement femelles 17, 17A des panneaux 2, 3, 4, 5 sont formés par les extrémités même des canaux d'une structure alvéolaire d'un profilé en matière plastique, à partir duquel sont prélevés, par découpe à angle droit, lesdits panneaux 2, 3, 4, 5, selon la longueur souhaitée - Ceci présente l'avantage majeur de pouvoir obtenir des profilés de longueur non limitée, et de les équiper ensuite à la demande. De plus, non seulement l'économie réalisable, sont obtenus des panneaux légers, pouvant être montés sur place, facilitant donc le transport.Preferably, the housings constituting the female interlocking areas 17, 17A of the panels 2, 3, 4, 5 are formed by the very ends of the channels of a honeycomb structure of a plastic profile, from which are taken, by cutting at right angles, said panels 2, 3, 4, 5, according to the desired length - This has the major advantage of being able to obtain profiles of unlimited length, and then equip them on demand. In addition, not only the economy achievable, are obtained lightweight panels, can be mounted on site, facilitating transport.
C'est ainsi que les panneaux pourront être réalisés en polychlorure de vinyle ou polyuréthane haute densité, et les pièces d'angle, par exemple, d'un matériau plus résistant. Selon le présent mode de réalisation, le profilé à partir duquel sont prélevés les panneaux 2, 3, 4, 5 à une section en T dont la branche
horizontale est constituée d'une pluralité de canaux de section quadrangulaire, et dont sa branche verticale est formée d'une pluralité de canaux également de section quadrangulaire, mais en nombre inférieur.Thus, the panels may be made of high density polyvinyl chloride or polyurethane, and the corner pieces, for example, of a more resistant material. According to the present embodiment, the section from which are taken the panels 2, 3, 4, 5 to a T-section whose branch horizontal consists of a plurality of channels of quadrangular section, and whose vertical branch is formed of a plurality of channels also quadrangular section, but in lower number.
Les figures montrent des profilés présentant une ligne de quatre canaux et une ligne adjacente de deux canaux.The figures show profiles having a line of four channels and an adjacent line of two channels.
Bien entendu, cette disposition pourrait être modifiée.Of course, this provision could be modified.
En tout état de cause, les extrémités des pièces d' angle comportent des éléments d'encastrement mâle selon une même disposition.In any case, the ends of the corner pieces comprise male recess elements in the same arrangement.
Selon une autre caractéristique de l' invention, le profilé en T définissant les panneaux 2, 3, 4, 5 ainsi que les éléments d'angle 6, 7, 8, 9 déterminent des épaulements latéraux longitudinaux 18 formant un cadre interne, après assemblage, destinés à recevoir des panneaux complémentaires constituant une ossature de renfort du coffrage ainsi obtenu.According to another characteristic of the invention, the T-section defining the panels 2, 3, 4, 5 as well as the corner elements 6, 7, 8, 9 determine longitudinal lateral shoulders 18 forming an internal frame, after assembly. , intended to receive complementary panels constituting a formwork reinforcement frame thus obtained.
La figure 4 montre particulièrement bien l'intérêt de l'invention, en ce sens qu'elle représente en pointillés, comme déjà évoqué, la position des panneaux 2 et 3, sans pièce d'angle selon l'invention.FIG. 4 shows particularly well the interest of the invention, in that it represents in dashed lines, as already mentioned, the position of the panels 2 and 3, without corner pieces according to the invention.
C'est ainsi que l'angle α3 serait constitué en fait par l'angle α2, c'est-à-dire un angle droit, si la pièce d'angle 6 ne donnait pas le fruit α4 et α5, la pièce d'angle 6 présentant par ailleurs à sa partie supérieure des angles αl à angle droit.
Thus the angle α3 would be constituted in fact by the angle α2, that is to say a right angle, if the corner piece 6 did not give the fruit α4 and α5, the piece of angle 6 also having at its upper part angles αl at right angles.
