Description
L'objet de la présente invention concerne un cintre susceptible d'adaptation à des profilés très divers d'un intrados ou plan de soutènement, c'est-à-dire essentiellement universel, pour son application dans tout type de travaux de génie civil qui aurait besoin de tout type de silhouette et doté d'un système de réglage très simple et commode à manier. Le cintre qui est proposé est de plus récupérable afin de le réutiliser ultérieure, pour construire des arcs, des voûtes et d'autres profilés assimilés ou contours divers, aussi bien en sens horizontal qu'en sens vertical.The object of the present invention relates to a hanger capable of adapting to very diverse profiles of a pressure surface or retaining plane, that is to say essentially universal, for its application in any type of civil engineering work which would need any type of silhouette and equipped with a very simple and convenient adjustment system to handle. The hanger which is proposed is more recoverable in order to reuse it later, to build arches, vaults and other assimilated profiles or various contours, both horizontally and vertically.
Les cintres connus jusqu'à présent consistent, en général, en des charpentes provisoires en bois ou métalliques sur lesquelles on construit les arcs et les voûtes durant la construction, présentant une couche d'extrados sur laquelle s'appuie l'intrados de la structure courbée durant la phase de construction ou de restauration.The hangers known up to now consist, in general, of temporary wooden or metallic frames on which arches and arches are built during construction, having a layer of upper surface on which the lower surface of the structure is supported. bent during the construction or restoration phase.
On connaît par le brevet EP-A-0404802 une structure constituée par un cintre pour construire des arcs et des voûtes ou ferme réutilisable, à montage variable apte pour être employée comme structure mobile ou fixe, notamment pour la mise en oeuvre d'arcs de maçonnerie et de béton et pour des applications de restauration comprenant une succession d'éléments modulaires de barre plats ayant la forme de "Y", articulés à un élément de formation en lame s'adaptant à l'intrados, dont les éléments en "Y" sont reliés entre eux par les noeuds supérieurs à des assises de support en équerre et articulés à la partie inférieure par des barres ayant une extrémité accrochée en pivotement comme charnière (voir figure 17) et avec une portion longitudinale destinée à être accrochée dans une glissière d'un élément en "Y" contigu.EP-A-0404802 discloses a structure constituted by a hanger for constructing arches and arches or reusable truss, with variable mounting suitable for being used as a mobile or fixed structure, in particular for the implementation of arches of masonry and concrete and for restoration applications comprising a succession of modular flat bar elements having the shape of "Y", articulated to a blade forming element adapting to the lower surface, including the elements in "Y "are interconnected by the upper nodes to angled support seats and articulated at the lower part by bars having one end pivotally hung as a hinge (see FIG. 17) and with a longitudinal portion intended to be hung in a slide a contiguous "Y" element.
Ladite ferme est essentiellement prévue pour s'adapter à un profilé d'un arc ou voûte, et une fois en position fixer lesdites glissières en rendant la structure rigide.Said truss is essentially designed to adapt to a profile of an arch or arch, and once in the fix position said slides by making the structure rigid.
L'ajustage ou réglage au chantier de la ferme du brevet EP-A-0404802 est compliqué car il exige que l'on libère (en dévissant des écrous), déplace et revisse lesdites barres coulissantes. De plus, cette structure est très complexe car elle comporte de nombreux noeuds d'articulation et un grand nombre de pièces, et pour la raidir il faut intervenir sur un grand nombre d'éléments de fixation (écrous) à manipulation délicate, notamment au chantier et par des ouvriers non spécialisés. De plus, en général il n'est pas faisable de raidir la structure, et la conformation d'un certain profil avant son montage au chantier, car les réglages éventuels ultérieurs sont compliqués, ce qui limite en forte mesure ses prestations.The adjustment or adjustment on the farm site of patent EP-A-0404802 is complicated because it requires that one frees (by unscrewing nuts), displaces and re-screws said sliding bars. In addition, this structure is very complex because it has many knots of articulation and a large number of parts, and to stiffen it it is necessary to intervene on a large number of fasteners (nuts) with delicate handling, in particular on site. and by unskilled workers. In addition, in general it is not feasible to stiffen the structure, and the conformation of a certain profile before its assembly on site, because the possible subsequent adjustments are complicated, which greatly limits its performance.
Le cintre selon cette invention propose une structure ayant des composants et un montage beaucoup plus simple et commode, susceptible de s'adapter à n'importe quel profilé d'arc, de voûte ou de pont et également applicable à des parements verticaux (jardins, bordures, etc.) qui est principalement caractérisé en ce qu'il comporte une suite de membres susceptibles d'agir en modelant à volonté une tôle à laquelle sont solidaires constitutifs du plan d'intrados ou délimiteur de coffrage et obligeant ladite tôle à adopter n'importe quelle silhouette désirée. Ainsi, le cintre selon cette invention peut se configurer avant son installation au chantier avec une adaptation parfaite ou bien être modelé au profilé de l'intrados ou plan à soutenir et ce avec des coûts de fabrication et d'installation très abordables, en accroissant le rendement, la versatilité et la sûreté de travail. Par ailleurs, il faut remarquer que les moyens de réglage pour régler le profilé de ladite tôle à une certaine silhouette sont faciles à manier, pouvant être manipulés pratiquement sans outils et, notamment, sans qu'il ne faille de personnel spécialisé.The hanger according to this invention provides a structure having components and a much simpler and more convenient mounting, capable of adapting to any arc, arch or bridge profile and also applicable to vertical facing (gardens, borders, etc.) which is mainly characterized in that it comprises a series of members capable of acting by modeling at will a sheet to which are integral constituting the lower surface or formwork delimiter and forcing said sheet to adopt n no matter what silhouette you want. Thus, the hanger according to this invention can be configured before its installation on the site with a perfect adaptation or else be shaped to the profile of the lower surface or plane to be supported and this with very affordable manufacturing and installation costs, increasing the performance, versatility and safety at work. Furthermore, it should be noted that the adjustment means for adjusting the profile of said sheet to a certain silhouette are easy to handle, being able to be handled practically without tools and, in particular, without the need for specialized personnel.
Comme détaille la revendication 1, le cintre selon l'invention comprend une tôle métallique rectangulaire, allongée, comme une bande, à grosseur susceptible de se cambrer et une largeur adaptée à l'étendue de l'intrados ou plan à soutenir, à laquelle sont fermement reliés, en diverses zones transversales de cette tôle, une pluralité de membres rigides, modeleurs, chacun étant relié au membre antérieur et postérieur de la série par des éléments tendeurs correspondants, co-alignés avec le développement longitudinal de la tôle. Ainsi, l'ensemble de ces membres modeleurs et éléments tendeurs donne lieu à une structure articulée dans laquelle en variant l'angle relatif de ces membres modeleurs, par l'application d'une certaine rotation à ces éléments tendeurs, on fournit un effort de modelage de la tôle, en rapprochant son profilé jusqu'à l'accommoder avec le contour, silhouette ou cambrure de l'intrados ou plan de soutènement à façonner.As detailed in
D'autres caractéristiques et avantages de l'invention seront bien compris dans la description suivante.Other characteristics and advantages of the invention will be well understood in the following description.
Afin de rendre plus facile l'explication suivante, deux feuilles de dessins sont annexées à la présente description dans lesquelles on a représenté un cas pratique de mise en oeuvre de l'appareil préconisé, qui n'est cité qu'à titre d'exemple non limitatif de la portée de cette invention.In order to make the following explanation easier, two sheets of drawings are annexed to the present description in which a practical case of implementation of the recommended device has been shown, which is only cited by way of example. not limiting the scope of this invention.
Dans ces dessins:In these drawings:
La figure 1 illustre une vue en perspective d'un cintre modelable, construit selon l'invention, en appréciant les possibilités pratiquement illimitées qu'elle offre de construire au moyen de celle-ci, n'importe quel profil d'appui pour un arc, une voûte ou un autre plan délimitant une construction.Figure 1 illustrates a perspective view of a modelable hanger, constructed according to the invention, appreciating the practically limitless possibilities which it offers to construct by means of it, any support profile for an arch , a vault or another plan delimiting a construction.
La figure 2 correspond à un détail élargi montrant un secteur dudit cintre en élévation latérale, qui montre l'interrelation entre deux membres modeleurs, fermement fixés à une tôle, par des barres tendeuses.Figure 2 corresponds to an enlarged detail showing a sector of said hanger in side elevation, which shows the interrelation between two modeling members, firmly fixed to a sheet metal, by tensioning bars.
La figure 3 est une section réalisée à travers le plan de coupe III - III de la figure 2. On a montré à cette figure l'union d'un étai de soutènement à un des membres modeleurs, légèrement modifié, pour y fixer une fourchette.FIG. 3 is a section made through the section plane III - III of FIG. 2. This figure has shown the union of a support prop to one of the modeler members, slightly modified, to fix a fork.
Dans la figure 4 on a illustré, schématiquement, un possible exemple de montage du cintre préconisé pour soutenir un arc durant sa construction ou restauration.In FIG. 4, a diagrammatic illustration of a possible mounting of the hanger recommended for supporting an arc during its construction or restoration has been illustrated.
Finalement les figures 5 et 6 illustrent un système alternatif pour le raccordement longitudinal de deux cintres avec le but de couvrir une plus vaste étendue d'arc.Finally Figures 5 and 6 illustrate an alternative system for the longitudinal connection of two hangers with the aim of covering a larger area of arc.
Conformément à ces figures, le cintre construit selon les principes de cette invention comporte une tôle métallique (1) rectangulaire, allongée, comme une bande, par exemple en acier inoxydable, ayant une grosseur susceptible de se cambrer (valeurs de 1,5 mm à 2 mm pour la plupart des applications courantes), et largeur adaptée à l'étendue de l'intrados ou plan à soutenir, à laquelle sont fermement reliés, en diverses zones transversales de ladite tôle (1), une pluralité de membres modeleurs (2), perpendiculaires à sa surface inférieure, chacun d'eux étant relié au membre antérieur et postérieur de la série par des éléments tendeurs correspondants, co-alignés au développement longitudinal de la tôle, constitués par des barres (3) ayant une portion centrale (3a) qui comporte des moyens pour leur manipulation en rotation (par exemple une configuration polygonale affectant cette portion centrale (3a), susceptible d'accouplement avec une clé et avantageusement munie d'orifices (6) transversaux, traversant pour l'agencement à travers eux de tiges pour rendre sa rotation plus aisé) et deux portions d'extrémité (3b, 3c) filetées respectivement à droite et à gauche à l'une ou l'autre des extrémités qui restent fixées en les vissant à l'intérieur de pièces (4, 5) libres en rotation autour d'un axe transversal à la tôle, tel que l'on voit dans la figure 3. Lesdites pièces (4, 5), avantageusement cylindriques sont pourvues d'un alésage diamétral (4a, 5a) fileté à l'intérieur pour y recevoir fixées en les vissant lesdites extrémités (3a, 3b) de deux barres consécutives tendeuses, pour chaque membre modeleur (2), tout cela conformément aux dessins des figures 1 et 2.In accordance with these figures, the hanger constructed according to the principles of this invention comprises a metal sheet (1) rectangular, elongated, like a strip, for example made of stainless steel, having a size capable of arching (values of 1.5 mm to 2 mm for most common applications), and width adapted to the extent of the pressure surface or plane to be supported, to which are firmly connected, in various transverse zones of said sheet (1), a plurality of modeling members (2 ), perpendicular to its lower surface, each of them being connected to the front and rear member of the series by corresponding tensioning elements, co-aligned with the longitudinal development of the sheet, constituted by bars (3) having a central portion ( 3a) which comprises means for their manipulation in rotation (for example a polygonal configuration affecting this central portion (3a), capable of coupling with a key and advantageously m united of transverse orifices (6), traversing for the arrangement through them of rods to make its rotation easier) and two end portions (3b, 3c) threaded respectively to the right and to the left at one or the other of the ends which remain fixed by screwing them inside parts (4, 5) which are free to rotate about an axis transverse to the sheet, as seen in FIG. 3. Said parts (4, 5), advantageously cylindrical, are provided with a diametral bore (4a, 5a) threaded inside to receive fixed therein by screwing said ends (3a, 3b) of two consecutive tensioning bars, for each modeler member (2), all this in accordance with the drawings of Figures 1 and 2.
Dans la figure 1, on voit que l'ensemble desdits membres modeleurs (2) et éléments tendeurs (3) constituent une structure articulée, ayant tous ses éléments dûment reliés avec raideur. Cela fait possible d'entraîner, par variation de l'angle relatif de ces membres modeleurs (2), lorsqu'on rapproche ou éloigne les parties de ceux-ci reliées entre elles par les éléments tendeurs (3) (en faisant tourner ces éléments dans un sens ou un autre) un effort de modelage à la tôle (1), en façonnant ou en modelant son profilé jusqu'à l'accommoder à la silhouette ou cambrure d'un intrados ou plan de soutènement à façonner.In Figure 1, we see that all of said members modelers (2) and tensioning elements (3) constitute an articulated structure, having all its elements duly connected with stiffness. This makes it possible to cause, by variation of the relative angle of these modeling members (2), when the parts thereof are connected or moved away from one another by the tensioning elements (3) (by rotating these elements in one direction or another) a modeling effort on the sheet (1), by shaping or by modeling its profile until it accommodates the silhouette or arch of a lower surface or support plane to be shaped.
Tel que l'on voit dans la figure 1, les membres modeleurs (2) sont agencés équidistants et alignés, centrés le long de la surface inférieure de ladite tôle (1) à laquelle ils sont fermement reliés de façon perpendiculaire.As seen in Figure 1, the modeling members (2) are arranged equidistant and aligned, centered along the lower surface of said sheet (1) to which they are firmly connected perpendicularly.
Dans la mise en oeuvre de l'exemple des dessins (voir notamment les figures 2 et 3) les membres modeleurs (2) ont été obtenus en pliant une tôle métallique qui façonne une partie inférieure en "U" (2a) entre les branches de laquelle sont montés en rotation, entre des orifices appropriés se faisant face, lesdites pièces (4, 5) tournantes, cylindriques, placés à deux niveaux différenciés. Une de ces pièces (4) possède des têtes (4b) qui dépassent à travers ces orifices et sont rivetées à l'extérieur sur la tôle, tandis que la deuxième pièce (5) reste simplement retenue en libre rotation entre les deux bras de la portion en "U" (2a), pour simplifier la construction. Comme montre la figure 3, les bras de ce "U" sont prolongés en deux branches (7, 8) divergentes, ayant une inclinaison plus ou moins grande selon la largeur de la tôle (1), dont les branches se terminent de pattes (7a, 8a), coudées, qui sont fermement reliées à la surface inférieure de cette tôle (1), avantageusement dans une zone à proximité de son bord, de sorte que ces pattes sont agencées transversalement au développement longitudinal de la tôle (1), pour dûment l'affecter, lorsque les membres (2) sont sollicités en inclinaison.In the implementation of the example of the drawings (see in particular Figures 2 and 3) the modeling members (2) were obtained by bending a metal sheet which shapes a lower part in "U" (2a) between the branches of which are rotatably mounted, between suitable orifices facing each other, said rotating cylindrical parts (4, 5), placed at two differentiated levels. One of these parts (4) has heads (4b) which protrude through these orifices and are riveted on the outside on the sheet, while the second part (5) simply remains retained in free rotation between the two arms of the "U" portion (2a), to simplify construction. As shown in Figure 3, the arms of this "U" are extended into two divergent branches (7, 8), having a greater or lesser inclination depending on the width of the sheet (1), the branches of which terminate in legs ( 7a, 8a), bent, which are firmly connected to the lower surface of this sheet (1), advantageously in an area close to its edge, so that these tabs are arranged transversely to the longitudinal development of the sheet (1), to duly affect it, when the members (2) are biased.
Afin de rendre la liaison des membres modeleurs (2) à la tôle (1), lesdites pattes (7a, 8a) présentent une protubérance pour leur liaison à la surface inférieure de la tôle (1), par soudure par résistance.In order to make the connection of the modeling members (2) to the sheet (1), said legs (7a, 8a) have a protrusion for their connection to the lower surface of the sheet (1), by resistance welding.
Par ailleurs et afin d'accroître la force des membres modeleurs, on a prévu des nervures raidissantes à ces branches divergentes (7, 8), obtenus dans une mise en oeuvre préférée par emboutissage (9) vers l'intérieur qui s'étend vers lesdites pattes (7a, 8a), en y donnant lieu à des gradins latéraux, aux deux côtés de cet emboutissage, qui forment des fentes (10) par rapport au plan de la tôle (1). Les fentes (10) peuvent agir comme des éléments auxiliaires pour le cas d'un raccordement longitudinal éventuel de deux de ces cintres, dans ce cas les bords d'une des tôles d'un des cintres emboîterait dans les fentes (10) d'extrémité de l'autre tôle (1) du deuxième cintre.Furthermore and in order to increase the strength of the modeling members, stiffening ribs have been provided for these divergent branches (7, 8), obtained in a preferred implementation by stamping (9) inwards which extends towards said tabs (7a, 8a), giving rise to lateral steps there, on both sides of this stamping, which form slots (10) relative to the plane of the sheet (1). The slots (10) can act as auxiliary elements in the case of a possible longitudinal connection of two of these hangers, in this case the edges of one of the sheets of one of the hangers would fit into the slots (10) of end of the other sheet (1) of the second hanger.
