Definitions
- the general principle is as follows: two vertical forms are kept apart by a system of tie rods, which is subsequently embedded in the filling material constituting the wall; the two forms when they are each made of insulating materials allow to realize the internal and external insulation of the wall; of course, depending on the case, the two forms may not be insulating if the need for insulation does not exist, or even only one of the two internal or external forms may be insulating depending on whether the insulation is necessary respectively for the indoors or outdoors.
- the forms are made of kinds of large hollow bricks whose side walls are insulating or not, or even insulating on one side and non-insulating on the other; in fact, the bricks are fitted vertically into each other, and the wall material is poured into the hollow parts of the bricks.
- the inventor has not proposed specific means to facilitate the continuous pouring of a wall between two walls held together by lost formwork elements.
- the second is that the use of common concrete (the most frequent) in the device according to PATURLE, favors the swelling of the formwork, and very often its bursting.
- each of the parts constituting the spacers require a specific dimension, which makes it necessary to manufacture expensive sets of complete molds.
- the invention provides a device for assembling formwork (2) fig. 2 used in lost formwork and imagined mainly as a function of its capacity to allow continuous filling, as easy as it is complete, of the space between the forms, these being composed, in the widest application of the invention, high density expanded polystyrene insulating building materials or other special hard foams, or non-insulating materials.
- These forms are thick rectangular panels, preferably flat stackable on edge.
- This device consists essentially of vertical U's (1) fig.1 equal, arranged consecutively to each other at regular spaces, and whose slides (a) fig.1 wings, perpendicular to the planes of the U, trapped in opposite grooves against undercut (3) fig.2 provided vertically in the thickness of the forms on their internal faces, are clipped symmetrically on horizontal honeycomb inserts (6) fig.3 integrated at mid-thickness in the edge upper horizontal (4) fig.2 of the underlying panel, and in the same action in the lower horizontal edge (5) fig.2 of the overlying panel thanks to the arrangement on each penetrated edge, of grooves (7) Fig. 2, female imprints of the penetrating section of the insert, so that the insert (6) once put in place, is completely trapped between the edges (4) and (5) kept contiguous and secured.
- the slides (a) of the wings of the same U (1) penetrate vertically after sliding in the above-mentioned undercut grooves (3) of the forms, so that these are kept in constant spacing and materialize between them a volume to be filled for the purpose of building a monolithic wall by continuous casting.
- the consecutive horizontal alveoal inserts (6) connecting between two forms are standards of the same length, which can be cut if necessary, and which consist in their most practical configuration, of two long vertical flats (8) fig .3 of length (L) kept parallel to each other by short vertical flats also (9) fig.
- the symmetrical housings (17) and (17 ') consist of two preferably identical compartments (11) and (12) fig. 3 for (17) and (11') and (12 ') fig. 3 for (17 '); the housings (17) and (17 ') are located one (17) at the upper edge and the other (17') at the lower edge of the internal lateral face of the insert (6) so that the height (h) of each housing preferably corresponds to one third of the total height (H) of the lateral face of the insert.
- the two symmetrical compartments (11) and (11 ') (respective housings (17) and (17')) situated against the wall of the insert (6) are intended, for the compartment (11 ') to be received by clipping the upper part of the slide (a) of the wing of a U (1) previously incorporated by vertical sliding in the undercut groove (3) fig. 2 of the underlying panel, and for the compartment (11) to receive by clipping the lower part of the slide (a) of the wing of a U previously incorporated by sliding in the undercut groove (in alignment of the first) of the overhanging branch.
- Both are clipped by means of a set of two vertical spring hooks (10) fig.1 arranged back to back vertically at each end of the slide (a) of the wing of a U ; these hooks are designed to resemble each other elastically by manual pressure exerted to make them penetrate the vertical compartments (11) and (11 '), and at the end of the stroke, relax horizontally to return to the position initial and clip symmetrically on the edges (16) fig.4 opposite compartments.
- These two spring hooks (10) and the compartments (11) and (11 ') in which they are then incorporated constitute a stable integral assembly, insofar as the thickness of the hooks corresponds by slight defect to the width of the compartments ( 11) and (11 ').
- the U (1) in a vertical position, located in a perpendicular plane between the two forms in which they are incorporated in symmetrical undercut grooves (3), are secured to these forms thanks to the compartments (11) and ( 11 ') of the internal face of these, along the inserts (6) consecutive arranged horizontally and embedded at mid-height in the edges in contact with these two consecutive vertical forms.
- the wings of U (1) fixed in the undercut grooves (3) of the forms and clipped into the vertical lateral housings (17) and (17 ') of the inserts (6) locking two successive forms by their horizontal edges (4) and (5) in contact make it possible to obtain a solid assembly, in order to flow continuously between the forms any originally fluid material (or practically), specifically intended for the construction of a wall, knowing that only will be embedded in the casting, as lost formwork elements, the volumes corresponding to the bases (14) fig.
- the bracing can be improved by nesting the ends (19) and (19 ') fig. 1 of the vertical parts of the wings of U, perpendicular to the forms and remaining outside these forms, (these ends (19) and (19 ') can moreover be arranged in reduction of section (r)), in cavities (20) and (20 ') fig. 1 of the same volume by slight excess as these ends and provided symmetrically perpendicular to these in the thickness of the edge of the base (14) of the U.
- the formwork before pouring, in addition to the fact that its internal elements represent a negligible volume between the forms, constitutes a set of undeniable rigidity and robustness by the fact that its structure as much longitudinal (along the inserts) that vertical (in the plane of the U) has all the attributes necessary for a perfect connection and overall compactness, while avoiding all of the drawbacks listed in the analysis of the PATURLE patent, presenting a technique from which we now deduce that it is very distant and much less efficient than that proposed by the invention.
- the entire device presented in the invention allows very high forms (practically up to the height of a storey), provided that the U and the inserts used are of sufficient robustness, which is technically feasible insofar as it is as much for the U as for the inserts, parts generally injected from originally hard materials, the rigidity resulting therefrom being able to be further optimized by the conformation of said parts as well as by various appropriate ribs.
- the device could very well use U in the base of construction (at the level of the floors) for a better seat, then H vertically nested in the U.
- an indexable angulator (21) consisting, as shown in Figures 5 and 6, of two preferably equal plates (x) and (y) secured in vertical hinge (v), each of the plates vertically integrating at its end an element (z) identical in all points to the wing portion of U comprising the slide (a), the two clipping systems each consisting of two vertical spring hooks (10) arranged back to back vertically at each end of the slide (a) and the bar (13) in the form of a flat parallelepiped secured to the upper part of the wing.
- the angulator can then be indexed to materialize, by the adequate opening of the hinge (v), the desired internal angle at the vertical junction of two formwork after the two elements (z) of the angulator have been placed in the undercut grooves and the inserts of each of the two forms, one of the forms and its integrated insert having been previously sawn vertically at a cutting angle equivalent to the angle which is to be obtained at the junction of said formwork.
- the angulation of a wall implies the internal angulation of the two external formwork of the wall and the equivalent internal angulation of the two internal formwork of the wall, constituting the lost formwork of said wall.

Description
On connaît depuis quelques années un certain nombre de systèmes constructifs utilisant des coffrages perdus; tous ces dispositifs s'adressent en général à des applications de maçonnerie isolante.We have known for a few years a number of constructive systems using lost formwork; all these devices are generally intended for insulating masonry applications.
Le principe général est le suivant: deux banches verticales sont maintenues écartées par un système de tirants, lequel est noyé par la suite dans le matériau de remplissage constituant le mur; les deux banches lorsqu'elles sont chacune constituées de matériaux isolants permettent de réaliser l'isolation interne et externe du mur; bien entendu, selon le cas, les deux banches peuvent ne pas être isolantes si le besoin d'isolation n'existe pas, ou encore une seule des deux banches intérieure ou extérieure peut être isolante selon que l'isolation est nécessaire respectivement à l'intérieur ou à l'extérieur.The general principle is as follows: two vertical forms are kept apart by a system of tie rods, which is subsequently embedded in the filling material constituting the wall; the two forms when they are each made of insulating materials allow to realize the internal and external insulation of the wall; of course, depending on the case, the two forms may not be insulating if the need for insulation does not exist, or even only one of the two internal or external forms may be insulating depending on whether the insulation is necessary respectively for the indoors or outdoors.
D'autres dispositifs existent: dans les uns, les banches sont constituées de sortes de grosses briques creuses dont les parois latérales sont isolantes ou non, voire isolante sur une face et non isolante de l'autre; par le fait, les briques sont emboîtées verticalement les unes dans les autres, et le matériau du mur est coulé dans les parties creuses des briques.Other devices exist: in some, the forms are made of kinds of large hollow bricks whose side walls are insulating or not, or even insulating on one side and non-insulating on the other; in fact, the bricks are fitted vertically into each other, and the wall material is poured into the hollow parts of the bricks.
Aujourd'hui, la construction a nettement opté pour le concept de banches verticales maintenues parallèles par des tirants de très faible section, permettant la réalisation d'un coulage en continu afin d'obtenir un mur monolithique.Today, construction has clearly opted for the concept of vertical forms kept parallel by tie rods of very small section, allowing the realization of a continuous casting in order to obtain a monolithic wall.
Un certain nombre de brevets connus et exploités dans le bâtiment ont mis en oeuvre des dispositifs tendant vers le résultat que l'invention se propose d'obtenir.A certain number of known and exploited patents in the building industry have implemented devices tending towards the result which the invention proposes to obtain.
Les brevets que nous allons citer ci-dessous sont à l'analyse très lointains de l'objet de l'invention bien que globalement destinés à la réalisation de coffrages dits perdus.The patents which we are going to cite below are very distant from the subject of the invention although generally intended for the production of so-called lost formwork.
Il s'agit principalement du brevet GB N° 1589113 (ASTL) qui protège des écarteurs de banches en profilés de section en I, ces écarteurs n'ayant pas pour destination de maintenir les banches parallèles afin de couler du béton entre elles, mais de les maintenir parallèles en vue de faire passer entre elles les réseaux d'eau, d'électricité et diverses câbleries utiles à la construction. La configuration des montages proposés par le brevet ASTL n'autoriserait pas le coulage du béton en continu, en raison de l'impossibilité de remplissage total qui résulte du montage des écarteurs sur les banches; il faut noter que le brevet ASTL concerne plus précisément des constructions de structures de bois.This is mainly GB patent No. 1589113 (ASTL) which protects form spacers in I-section profiles, these spacers not intended to keep the formwork parallel in order to pour concrete between them, but to keep them parallel in order to pass between them the water, electricity and various cables useful for construction. The configuration of the assemblies proposed by the ASTL patent would not allow the pouring of the concrete continuously, because of the impossibility of total filling which results from the mounting of the spacers on the formwork; it should be noted that the ASTL patent relates more precisely to wooden structure constructions.
Le brevet US N° 3562991 (KUSTUSCH) revendique en fait un dispositif de coffrage dont le but principal est d'emprisonner verticalement des tubes ou carrés de forte section susceptibles d'autoriser le passage de tous conduits.US Patent No. 3562991 (KUSTUSCH) claims in fact a formwork device whose main purpose is to vertically trap tubes or squares of large section likely to authorize the passage of all conduits.
Son inventeur n'a pas proposé de moyens spécifiques pour faciliter le coulage en continu d'un mur entre deux parois maintenues entre elles par des éléments de coffrage perdu.The inventor has not proposed specific means to facilitate the continuous pouring of a wall between two walls held together by lost formwork elements.
Tel n'est pas le cas du brevet français PATURLE dans lequel les inventeurs OTT et JALABERT utilisent des éléments de coffrage perdu à l'intérieur d'un dispositif plutôt complexe dont le but est bien de maintenir verticalement parallèles deux banches isolantes ou non, afin de couler en continu entre elles un matériau spécifique de construction de mur, mais présentant plusieurs inconvénients dont certains majeurs.This is not the case with the French PATURLE patent in which the inventors OTT and JALABERT use formwork elements lost inside a rather complex device, the aim of which is to keep two insulating panels, or not, vertically parallel, in order to to continuously flow between them a specific wall construction material, but having several drawbacks, some of them major.
Le premier est que trop souvent, la mise en place des armatures est très compliquée du fait de la gêne occasionnée par le volet d'écartement, obligatoirement à verrouiller manuellement préalablement à la mise en place de ces armatures.The first is that too often, the installation of the frames is very complicated due to the discomfort caused by the spacer flap, necessarily to be locked manually before the establishment of these frames.
Cela est particulièrement dérangeant pour l'édification des premiers rangs, et occasionne en outre une perte de temps considérable.This is particularly disturbing for the construction of the front rows, and also causes a considerable loss of time.
Le second est que l'utilisation de béton courant (la plus fréquente) dans le dispositif selon PATURLE, favorise le gonflement du coffrage, et très souvent son éclatement.The second is that the use of common concrete (the most frequent) in the device according to PATURLE, favors the swelling of the formwork, and very often its bursting.
Le troisième est que dans le système PATURLE, pour la réalisation de murs de différentes épaisseurs, chacune des pièces constituant les écarteurs (y compris les équerres d'angle) requièrent une dimension spécifique, ce qui rend nécessaire la fabrication onéreuse de jeux complets de moules d'injection - dans la mesure où le système PATURLE (comme celui de l'invention) met en oeuvre des éléments moulés de matière plastique -.The third is that in the PATURLE system, for the production of walls of different thicknesses, each of the parts constituting the spacers (including the angle brackets) require a specific dimension, which makes it necessary to manufacture expensive sets of complete molds. injection - insofar as the PATURLE system (like that of the invention) implements molded plastic elements -.
La description qui va suivre des moyens mis en oeuvre par l'invention pourra clairement démontrer ses différences fondamentales d'avec le brevet PATURLE.The following description of the means used by the invention will clearly demonstrate its fundamental differences from the PATURLE patent.
L'invention propose un dispositif d'assemblage de banches (2) fig. 2 utilisé en coffrage perdu et imaginé principalement en fonction de sa capacité à permettre un remplissage en continu aussi facile que complet de l'espace compris entre les banches, celles-ci étant composées, dans l'application la plus large de l'invention, de matériaux de construction isolants de type polystyrène expansé haute densité ou autres mousses dures spéciales, ou de matériaux non isolants.The invention provides a device for assembling formwork (2) fig. 2 used in lost formwork and imagined mainly as a function of its capacity to allow continuous filling, as easy as it is complete, of the space between the forms, these being composed, in the widest application of the invention, high density expanded polystyrene insulating building materials or other special hard foams, or non-insulating materials.
Ces banches sont des panneaux rectangulaires épais de préférence plans empilables sur chant.These forms are thick rectangular panels, preferably flat stackable on edge.
Ce dispositif consiste essentiellement en des U verticaux (1) fig.1 égaux, disposés consécutivement les uns aux autres à espaces réguliers, et dont les glissières (a) fig.1 des ailes, perpendiculaires aux plans des U, prisonnières dans des gorges opposées à contre dépouille (3) fig.2 prévues verticalement dans l'épaisseur des banches sur leurs faces internes, sont clipées en symétrie sur des inserts alvéoalaires horizontaux (6) fig.3 intégrés à mi-épaisseur dans le chant horizontal supérieur (4) fig.2 du panneau sous-jacent, et dans la même action dans le chant horizontal inférieur (5) fig.2 du panneau sus-jacent grâce à l'aménagement sur chaque chant pénétré, de gorges (7) fig.2, empreintes femelles de la section pénétrante de l'insert, de telle sorte que l'insert (6) une fois mis en place, soit complètement emprisonné entre les chants (4) et (5) maintenus contigus et solidarisés.This device consists essentially of vertical U's (1) fig.1 equal, arranged consecutively to each other at regular spaces, and whose slides (a) fig.1 wings, perpendicular to the planes of the U, trapped in opposite grooves against undercut (3) fig.2 provided vertically in the thickness of the forms on their internal faces, are clipped symmetrically on horizontal honeycomb inserts (6) fig.3 integrated at mid-thickness in the edge upper horizontal (4) fig.2 of the underlying panel, and in the same action in the lower horizontal edge (5) fig.2 of the overlying panel thanks to the arrangement on each penetrated edge, of grooves (7) Fig. 2, female imprints of the penetrating section of the insert, so that the insert (6) once put in place, is completely trapped between the edges (4) and (5) kept contiguous and secured.
Les glissières (a) des ailes d'un même U (1) pénètrent verticalement après glissement dans les gorges à contre dépouille (3) précitées des banches, de telle sorte que celles-ci soient maintenues en espacement constant et matérialisent entre elles un volume à combler dans le but de la construction d'un mur monolithique par coulage continu.The slides (a) of the wings of the same U (1) penetrate vertically after sliding in the above-mentioned undercut grooves (3) of the forms, so that these are kept in constant spacing and materialize between them a volume to be filled for the purpose of building a monolithic wall by continuous casting.
Les inserts alvéoalaires horizontaux consécutifs (6) de liaison entre deux banches sont des standards de même longueur, que l'on peut couper le cas échéant, et qui sont constitués dans leur configuration la plus pratique, de deux méplats longs verticaux (8) fig.3 de longueur (L) maintenus parallèles entre eux par des méplats courts verticaux aussi (9) fig.3 de longueur (l) et égaux entre eux, disposés à intervalles réguliers le long et entre les méplats longs, de telle façon que le volume d'un insert (6) s'inscrive dans un parallélépipède ayant pour longueur la longueur (L) d'un méplat long (8), pour largeur la longueur (l) d'un méplat court (9) et pour hauteur la largeur (H) d'un méplat long (ou d'un méplat court) (8) ou (9), encore qu'il ne soit pas prépondérant que les méplats longs et les méplats courts aient la même hauteur (H) pour jouer le rôle technique qui leur est dévolu.The consecutive horizontal alveoal inserts (6) connecting between two forms are standards of the same length, which can be cut if necessary, and which consist in their most practical configuration, of two long vertical flats (8) fig .3 of length (L) kept parallel to each other by short vertical flats also (9) fig. 3 of length (l) and equal to each other, arranged at regular intervals along and between the long flats, so that the volume of an insert (6) is inscribed in a parallelepiped having for length the length (L) of a long flat (8), for width the length (l) of a short flat (9) and for height the width (H) of a long flat (or a short flat) (8) or (9), although it is not preponderant that the long flat and the short flat have the same height (H) to play the technical role assigned to them.
Afin que les accrochages des glissières (a) des ailes des U (1) faisant fonction de rails puissent être effectués facilement dans les inserts horizontaux (6), ceux-ci sont munis latéralement sur leur face interne de logements verticaux parallélépipédiques (17) et (17') fig.3 centrés en symétrie et en bout de chacun des méplats courts (9) de l'insert (6), définissant les alvéoles de celui-ci perpendiculairement aux méplats longs (8), de telle façon qu'après emprisonnement de l'insert entre les banches, ces logements restent à l'extérieur des banches sur les faces internes de celles-ci (2) fig.2.So that the hooking of the slides (a) of the wings of the U (1) acting as rails can be carried out easily in the horizontal inserts (6), these are provided laterally on their internal face with parallelepipedal vertical housings (17) and (17 ') fig. 3 centered in symmetry and at the end of each of the short flats (9) of the insert (6), defining the cells of the latter perpendicular to the long flats (8), so that after imprisonment of the insert between the forms, these housings remain outside the forms on the internal faces of the latter (2) fig.2.
Les logements (17) et (17') symétriques entre eux se composent de deux compartiments préférentiellement identiques (11) et (12) fig.3 pour (17) et (11') et (12') fig.3 pour (17'); les logements (17) et (17') sont situés l'un (17) au bord supérieur et l'autre (17') au bord inférieur de la face latérale interne de l'insert (6) de telle façon que la hauteur (h) de chaque logement corresponde préférentiellement au tiers de la hauteur totale (H) de la face latérale de l'insert.The symmetrical housings (17) and (17 ') consist of two preferably identical compartments (11) and (12) fig. 3 for (17) and (11') and (12 ') fig. 3 for (17 '); the housings (17) and (17 ') are located one (17) at the upper edge and the other (17') at the lower edge of the internal lateral face of the insert (6) so that the height (h) of each housing preferably corresponds to one third of the total height (H) of the lateral face of the insert.
Les deux compartiments symétriques (11) et (11') (des logements respectifs (17) et (17')) situés contre la paroi de l'insert (6) sont destinés, pour le compartiment (11') à recevoir en clipage la partie supérieure de la glissière (a) de l'aile d'un U (1) préalablement incorporée par glissement vertical dans la gorge à contre dépouille (3) fig. 2 de la banche sous-jacente, et pour le compartiment (11) à recevoir en clipage la partie inférieure de la glissière (a) de l'aile d'un U préalablement incorporée par glissement dans la gorge à contre dépouille (en alignement de la première) de la banche sus-jacente.The two symmetrical compartments (11) and (11 ') (respective housings (17) and (17')) situated against the wall of the insert (6) are intended, for the compartment (11 ') to be received by clipping the upper part of the slide (a) of the wing of a U (1) previously incorporated by vertical sliding in the undercut groove (3) fig. 2 of the underlying panel, and for the compartment (11) to receive by clipping the lower part of the slide (a) of the wing of a U previously incorporated by sliding in the undercut groove (in alignment of the first) of the overhanging branch.
L'un et l'autre clipage sont réalisés par le moyen d'un ensemble de deux crochets ressorts verticaux (10) fig.1 disposés dos à dos verticalement à chaque bout de la glissière (a) de l'aile d'un U; ces crochets sont étudiés pour se rapprocher élastiquement l'un de l'autre par la pression manuelle exercée pour les faire pénétrer dans les compartiments verticaux (11) et (11'), et en bout de course, se détendre horizontalement pour revenir en position initiale et se cliper symétriquement sur les rebords (16) fig.4 opposés des compartiments. Ces deux crochets ressorts (10) et les compartiments (11) et (11') dans lesquels ils se trouvent alors incorporés constituent un ensemble solidarisé stable, dans la mesure où l'épaisseur des crochets correspond par léger défaut à la largeur des compartiments (11) et (11').Both are clipped by means of a set of two vertical spring hooks (10) fig.1 arranged back to back vertically at each end of the slide (a) of the wing of a U ; these hooks are designed to resemble each other elastically by manual pressure exerted to make them penetrate the vertical compartments (11) and (11 '), and at the end of the stroke, relax horizontally to return to the position initial and clip symmetrically on the edges (16) fig.4 opposite compartments. These two spring hooks (10) and the compartments (11) and (11 ') in which they are then incorporated constitute a stable integral assembly, insofar as the thickness of the hooks corresponds by slight defect to the width of the compartments ( 11) and (11 ').
Ainsi, les U (1) en position verticale, situés dans un plan perpendiculaire entre les deux banches dans lesquelles ils sont incorporés dans des gorges à contre dépouille (3) symétriques, se trouvent solidarisés avec ces banches grâce aux compartiments (11) et (11') de la face interne de celles-ci, le long des inserts (6) consécutifs disposés horizontalement et noyés à mi-hauteur dans les chants en contact de ces deux banches verticales consécutives.Thus, the U (1) in a vertical position, located in a perpendicular plane between the two forms in which they are incorporated in symmetrical undercut grooves (3), are secured to these forms thanks to the compartments (11) and ( 11 ') of the internal face of these, along the inserts (6) consecutive arranged horizontally and embedded at mid-height in the edges in contact with these two consecutive vertical forms.
Afin d'obtenir un contreventement efficace de l'assemblage déjà clipé qui vient d'être décrit, il a été prévu, solidarisé de la partie supérieure d'une aile de U et en symétrie théorique de la partie glissière (a) de cette aile de U par rapport au plan des deux crochets ressorts (10) un parallélépipède plat (13) fig. 1, dont la hauteur utile, équivalente ici à trois fois la hauteur (h) d'un compartiment, pour correspondre en fait à la hauteur totale (H) de l'insert, permet son introduction en enfilade dans les deux compartiments symétriques externes (12) et (12') superposés et préférentiellement identiques aux compartiments (11) et (11') comme il a été dit. Le calage obtenu de cette manière contemporainement au clipage permet d'obtenir la meilleure robustesse possible de l'assemblage clipé précité, selon la figure 4.In order to obtain an effective bracing of the already clipped assembly which has just been described, provision has been made, secured to the upper part of a U-shaped wing and in theoretical symmetry of the slide part (a) of this wing. of U relative to the plane of the two spring hooks (10) a flat parallelepiped (13) fig. 1, whose useful height, here equivalent to three times the height (h) of a compartment, to correspond in fact to the total height (H) of the insert, allows its introduction in a row in the two external symmetrical compartments ( 12) and (12 ') superimposed and preferably identical to the compartments (11) and (11') as has been said. The setting obtained in this way contemporaneously with the clipping makes it possible to obtain the best possible robustness of the aforementioned clipped assembly, according to FIG. 4.
Ainsi, les ailes de U (1) fixées dans les gorges à contre dépouille (3) des banches et clipées dans les logements verticaux (17) et (17') latéraux internes des inserts (6) verrouillant deux banches successives par leurs chants horizontaux (4) et (5) en contact, permettent d'obtenir un montage solide, afin de couler en continu entre les banches tout matériau originellement fluide (ou pratiquement), spécifiquement destiné à la construction d'un mur, en sachant que seuls seront noyés dans la coulée, en tant qu'éléments de coffrage perdu, les volumes correspondant aux bases (14) fig. 1 des U et aux portions des ailes de U externes aux banches, ce qui représente un volume dérisoire d'éléments noyés par rapport au volume du matériau à couler, d'autant plus que l'épaisseur des profils des U peut être réduite à une très faible dimension compte tenu de la très grande rigidité autorisée par la compacité du montage dans le concept de l'invention.Thus, the wings of U (1) fixed in the undercut grooves (3) of the forms and clipped into the vertical lateral housings (17) and (17 ') of the inserts (6) locking two successive forms by their horizontal edges (4) and (5) in contact, make it possible to obtain a solid assembly, in order to flow continuously between the forms any originally fluid material (or practically), specifically intended for the construction of a wall, knowing that only will be embedded in the casting, as lost formwork elements, the volumes corresponding to the bases (14) fig. 1 of the U and to the portions of the wings of U external to the formwork, which represents a paltry volume of embedded elements relative to the volume of the material to be poured, all the more since the thickness of the profiles of the U can be reduced to a very small dimension given the very high rigidity allowed by the compactness of the assembly in the concept of the invention.
Au surplus, le contreventement peut être amélioré par l'emboîtement des extrémités (19) et (19') fig. 1 des parties verticales des ailes de U, perpendiculaires aux banches et restant à l'extérieur de ces banches, (ces extrémités (19) et (19') pouvant d'ailleurs être aménagées en réduction de section (r)), dans des cavités (20) et (20') fig.1 de même volume par léger excès que ces extrémités et prévues symétriquement à l'aplomb de celles-ci dans l'épaisseur du chant de la base (14) du U.Furthermore, the bracing can be improved by nesting the ends (19) and (19 ') fig. 1 of the vertical parts of the wings of U, perpendicular to the forms and remaining outside these forms, (these ends (19) and (19 ') can moreover be arranged in reduction of section (r)), in cavities (20) and (20 ') fig. 1 of the same volume by slight excess as these ends and provided symmetrically perpendicular to these in the thickness of the edge of the base (14) of the U.
L'assemblage des extrémités (19) et (19') dans les cavités (20) et (20') s'opère simultanément au clipage des crochets (10) ainsi qu'à l'enfilage de la barrette (13), et s'effectue ainsi dans un plan perpendiculaire à eux, ce qui permet d'obtenir un contreventement efficace.The assembly of the ends (19) and (19 ') in the cavities (20) and (20') takes place simultaneously with the clipping of the hooks (10) as well as with the threading of the bar (13), and thus takes place in a plane perpendicular to them, which makes it possible to obtain effective bracing.
Pour renforcer encore s'il en était besoin la rigidité d'un plan vertical de U consécutifs une fois clipés dans les compartiments correspondants des inserts, il a été aménagé au centre des bases (14) des U des compartiments centraux creux (15) fig.1 préférentiellement parallélépipèdiques destinés à recevoir verticalement en enfilade des fers préférentiellement plats (18) fig.4 de liaison.To further strengthen if necessary the rigidity of a vertical plane of consecutive U once clipped into the corresponding compartments of the inserts, it has been fitted in the center of the bases (14) of the U of the hollow central compartments (15) fig .1 preferentially parallelepipedic intended to receive vertically in a row preferentially flat irons (18) fig.4 of connection.
De cette manière, le coffrage, avant coulage, outre le fait que ses éléments internes représentent un volume négligeable entre les banches, constitue un ensemble d'une rigidité et d'une robustesse incontestables par le fait que sa structure autant longitudinale (le long des inserts) que verticale (dans le plan des U) présente tous les attributs nécessaires à une parfaite solidarisation et compacité d'ensemble, et ce en évitant la totalité des inconvénients énumérés dans l'analyse du brevet PATURLE, présentant une technique dont on déduit maintenant qu'elle est très éloignée et beaucoup moins performante que celle proposée par l'invention.In this way, the formwork, before pouring, in addition to the fact that its internal elements represent a negligible volume between the forms, constitutes a set of undeniable rigidity and robustness by the fact that its structure as much longitudinal (along the inserts) that vertical (in the plane of the U) has all the attributes necessary for a perfect connection and overall compactness, while avoiding all of the drawbacks listed in the analysis of the PATURLE patent, presenting a technique from which we now deduce that it is very distant and much less efficient than that proposed by the invention.
Pour terminer, l'ensemble du dispositif présenté dans l'invention permet la réalisation de banches très hautes (pratiquement jusqu'à la hauteur d'un étage), pour autant que les U et les inserts utilisés soient de robustesse suffisante, ce qui est techniquement réalisable dans la mesure où il s'agit autant pour les U que pour les inserts, de pièces généralement injectées à partir de matériaux originellement durs, la rigidité en résultant pouvant être encore optimisée par la conformation desdites pièces ainsi que par différents nervurages appropriés.Finally, the entire device presented in the invention allows very high forms (practically up to the height of a storey), provided that the U and the inserts used are of sufficient robustness, which is technically feasible insofar as it is as much for the U as for the inserts, parts generally injected from originally hard materials, the rigidity resulting therefrom being able to be further optimized by the conformation of said parts as well as by various appropriate ribs.
L'objectif de la meilleure résistance des matériaux pourrait aussi rendre pertinent que la portion de base (14) de U (entre les cavités (20) et (20') elles-mêmes fonctionnellement inamovibles), incluant le compartiment creux (15), puisse être remontée, toujours horizontalement, à un niveau nécessaire (le U devenant en quelque sorte un H) en restant parfaitement dans l'intégralité du moyen de l'invention.The objective of better resistance of materials could also make it relevant that the portion base (14) of U (between the cavities (20) and (20 ') themselves functionally irremovable), including the hollow compartment (15), can be raised, still horizontally, to a necessary level (the U becoming somehow an H) remaining perfectly in the entirety of the means of the invention.
Ainsi, le dispositif pourrait très bien utiliser des U en base de construction (au niveau des planchers) pour une meilleure assise, puis des H verticalement emboîtés dans les U.Thus, the device could very well use U in the base of construction (at the level of the floors) for a better seat, then H vertically nested in the U.
Dans le cadre de l'invention, il restera régulièrement à résoudre le problème du coffrage au niveau des angles de murs; pour cela, on utilisera un angulateur indexable (21) constitué, comme le montrent les figures 5 et 6, de deux plateaux préférentiellement égaux (x) et (y) solidarisés en charnière verticale (v), chacun des plateaux intégrant verticalement à son extrémité un élément (z) identique en tous points à la portion d'aile de U comprenant la glissière (a), les deux systèmes de clipage constitués chacun de deux crochets ressorts verticaux (10) disposés dos à dos verticalement à chaque bout de la glissière (a) et la barrette (13) en forme de parallélépipède plat solidarisée de la partie supérieure de l'aile.Within the framework of the invention, it will regularly remain to solve the problem of formwork at the angles of walls; for this, we will use an indexable angulator (21) consisting, as shown in Figures 5 and 6, of two preferably equal plates (x) and (y) secured in vertical hinge (v), each of the plates vertically integrating at its end an element (z) identical in all points to the wing portion of U comprising the slide (a), the two clipping systems each consisting of two vertical spring hooks (10) arranged back to back vertically at each end of the slide (a) and the bar (13) in the form of a flat parallelepiped secured to the upper part of the wing.
Sur les figures 5 et 6, il a été utilisé à dessein les signes de référence (a), (10) et (13) en correspondance avec ceux d'une aile d'un U (fig. 1).In FIGS. 5 and 6, the reference signs (a), (10) and (13) have been used on purpose in correspondence with those of a wing of a U (fig. 1).
Ainsi, l'angulateur peut être alors indexé pour matérialiser, par l'ouverture adéquate de la charnière (v), l'angle interne désiré à la jonction verticale de deux banches après que les deux éléments (z) de l'angulateur aient été mis en place dans les gorges à contre dépouille et les inserts de chacune des deux banches, l'une des banches et son insert intégré ayant été préalablement sciés verticalement selon un angle de coupe équivalent à l'angle que l'on veut obtenir à la jonction desdites banches.Thus, the angulator can then be indexed to materialize, by the adequate opening of the hinge (v), the desired internal angle at the vertical junction of two formwork after the two elements (z) of the angulator have been placed in the undercut grooves and the inserts of each of the two forms, one of the forms and its integrated insert having been previously sawn vertically at a cutting angle equivalent to the angle which is to be obtained at the junction of said formwork.
L'angulation d'un mur implique l'angulation interne des deux banches externes du mur et l'angulation interne équivalente des deux banches internes du mur, constituant le coffrage perdu dudit mur.The angulation of a wall implies the internal angulation of the two external formwork of the wall and the equivalent internal angulation of the two internal formwork of the wall, constituting the lost formwork of said wall.
